    DESCRIPTION
    Device and procedure for monitoring and control in telescopic lighting towers Technical sector
    The present invention relates to the field of means for controlling the conditions of installation, operation and assurance of structural safety and prevention of overturning in telescopic lighting towers, preferably transportable.
    The fundamental object of the invention is to develop a monitoring and control device and procedure that allows automatic adjustment of the height of the mast and the height and pressure on the support elements of the base in a telescopic tower, so as to minimize the risk of overturning and the maximum deployment of the mast is allowed.
    Background of the invention
    At present, the need for lighting or supplementary lighting, makes the use of autonomous lighting towers in numerous environments, from construction sites to public events, is widely extended. Given the functionality of these devices, most of them consist of a mast of greater or lesser length, typically telescopic, which is deployed to place the light source as high as possible and thus illuminate a larger surface.
    The safe use of a telescopic lighting tower requires ensuring structural safety and the prevention of overturning in all conditions of use of the tower.
    In the design phase of a telescopic lighting tower, it must be ensured that the tower complies with current regulations regarding structural safety and rollover prevention.
    However, although a good design of the telescopic tower is made, structural safety and the prevention of tipping can be compromised by the installation conditions of the tower base, the mast deployment conditions and other factors external to the installation of the base itself.
    Some of these factors related to the installation of the telescopic tower, directly determine the structural safety and / or the moment of overturning.
    Direct factors
    Mechanical factors of the different parts of a telescopic lighting tower
    • Horizontality of the base elements of the telescopic lighting tower and homogeneous load distribution in the support elements of the telescopic tower,
    • Mast extension level
    • Orientation of the luminaires that determine the effective surface facing the wind in certain operating conditions.
    • Degradation of the quality or resistance of structural elements of the tower.
    Site constraints
    • Terrain characteristics, such as resistance and others
    • Presence of obstacles in the field that hinder its good installation
    • Sloping or sloping terrain
    • Presence of objects or obstacles that compromise the extension of the mast
    On the other hand, other external factors may indirectly condition the structural safety and / or cause the structure to overturn during the tower's use phase.
    Indirect factors
    Environmental factors, wind, rain, ice;
    Conditions of use and handling of the tower, impacts, blows, etc.
    The surface facing the wind
    On this basis, solutions that define the essential structure or intend to incorporate complementary functions have been protected

    Thus, the GB2491421 patent describes a mobile light tower comprising a base unit that includes an extensible mast adapted to move between a retracted position and an extended position, including a controller and a wind speed sensor, the controller being adapted to lower the extendable mast to an intermediate position, between the retracted position and the extended position, when the wind speed sensor determines that a predetermined wind speed is exceeded.
    Another solution is presented in the patent AU2010100828 in which a solar lighting tower comprising a retractable mast is described; a wind speed detector that acts for the retraction of the mast when the wind speed exceeds a predetermined threshold, also including GPS detection means and a high voltage proximity warning system.
    The use of wind meters as a means to ensure the stability of a mast, would not serve to detect other conditions that led to the collapse of the tower, such as blows of machinery, landslide, vibrations of the ground due to explosions or machinery or mechanical failures of the own tower.

    The procedure for monitoring and controlling the device in telescopic towers, for the automatic control of the conditions of installation, operation and assurance of structural safety and rollover prevention, comprises the following phases:
    Initialization Phase 1
    Phase 2 monitoring and control of the installation of the tower base.
    Phase 3 monitoring and control of the deployment of the telescopic mast.
    Phase 4 monitoring and control of the operating conditions of the telescopic lighting tower In phase 1, initialization
    Firstly, the monitoring and control device is installed in the telescopic lighting tower: installing at least one lower sensor module, at least one upper sensor module and an electronic control module in the telescopic lighting tower, connecting directly to the electronic control module, through the output connections for
    • act on the support elements of the base of the telescopic lighting tower
    • act on the mast extension mechanism
    • act on the mast retraction mechanism
    • act on the luminaire orientation mechanism
    • act on the visual or acoustic aids of indication to the user
    • act on other towers or alarm outputs for elements external to the system described.
    Next, the device is connected to the sensor modules (lower sensor module and upper sensor module) and the connection between them is checked
    • The signal adaptation mode of the electronic control module foresees adapting the analog or digital data transmitted to the process logic. wired by standard or dedicated protocols or wirelessly by standard or dedicated protocols, by one or more modules lower sensor, upper sensor or any other integrated in the telescopic lighting tower.
    Subsequently, the following thresholds are checked
    • Base warning threshold
    • Critical base threshold
    • Mast warning threshold
    • Critical mast threshold
    Finally, through the processing mode of the electronic control module, the calculation of the indicators and levels that will be used in the following phases of the procedure is initialized
    • Balance indicator of the base, it is an indicator proportional to the horizontality of the base and the distribution of loads between the support elements. This indicator is calculated from the monitoring signals of the lower sensor module.
    • Mast balance indicator, is an indicator proportional to the relative position of the upper end of the mast relative to the reference position of the base and is calculated from the signals of the measurement sensors integrated in the upper sensor module and the Pressure sensor signals integrated in the lower sensor module.
    • Level of current extension of the mast, determined by the signals of the height sensor, of the upper sensor module, directly or by calculation and defines the height of the mast end at each moment.
    • Level of safe extension of the mast, determined taking into account the values of the Balance indicator of the base, of the Balance indicator of the mast, calculated at any time, the signals of the distance sensor, the height sensor and any other sensor relevant that defines the extension of the mast for its safe operation.

    or the distance from the base of the telescopic lighting tower, to the nearest object on the projected mast extension path,
    or the maximum length of the mast according to design and
    or the maximum level of user defined mast extension.
    • Maximum level of extension of the mast, is the maximum level of extension in the phase of monitoring and control of the deployment of the mast, for which a balance indicator of the mast below the warning threshold of the mast is obtained.
    Phase 2 monitoring and control of the installation of the base of the telescopic lighting tower.
    It starts when the start button (20) is activated or when the device is powered and certain signals are received in the lower sensor module (3), typically contact or force signals, through the pressure sensors (31 ).
    The electronic control module (6) calculates the balance indicator of the base (1) from the signals of the lower sensor module (3).
    The balance indicator is proportional to the horizontality of the base and the distribution of loads between the support elements. Therefore, it is assumed that if any of the support elements of the telescopic lighting tower is not in contact with the ground, an indicator value greater than the basic critical threshold will be obtained.
    The base equilibrium indicator is compared with the predefined base thresholds in terms of structural safety and prevention against rollover, base warning threshold and critical base threshold, activating one of the following action strategies, depending on the result said comparison:
    • Validation of the correct installation of the base and calibration of the lower sensor module
    o If the base balance indicator is lower than the base warning threshold, it is considered that the installation of the base of the telescopic lighting tower is correct in terms of structural safety and prevention against overturning.
    o The device calibrates the lower sensor module in that position to be considered as the reference position of the base installation.
    o The process can continue with the next phase of the procedure, activating internally the signal ‘Correct base installation’
    • Assistance for the correct installation of the base
    o If the base balance indicator is equal to or greater than the base warning threshold, it is considered that the installation of the base (1) of the telescopic lighting tower does not meet the minimum requirements of structural safety and prevention from the moment of overturn.
    o The device defines the strategy of action in the support elements of the tower base for proper installation, activating the outputs for the support element of the tower base (61) and / or the acoustic or visual outputs ( 65).
    o This action strategy allows to reduce significantly the time necessary for the correct installation of the base since it assists the operator in charge of the installation during the process.
    o Through the processing mode, the calculation of the base equilibrium indicator is repeated iteratively, compared with the warning and critical thresholds of the base, definition of action strategy, until the correct conditions of the installation of the installation are met. tower base.
    In this phase the effects affecting the stability and the correct installation of the base of the telescopic lighting tower are taken into consideration. It is very possible that, in addition to the wind, other conditions

    weather conditions (rain, hail, snow and / or ice formation) or other factors that affect the condition of the ground where the lighting telescopic tower is put into operation may have an effect on the stability of the base of the tower and make the tuning of the telescopic tower of unstable lighting.
    The same magnitude of an external cause may affect the stability of a telescopic tower differently, depending on the design and installation characteristics.
    For example, the same wind speed may compromise stability in a tower that is too high or not properly installed, while the same magnitude may not affect the stability of a tower with the base properly seated and with a different luminaire orientation.
    Traffic and / or nearby activity can also cause vibrations and affect the correct installation of the lighting tower: for example, in a mine, trucks passing near a lighting tower.
    Phase 3 monitoring and control of the deployment of the telescopic mast.
    It starts when the signal ‘Correct base installation’ is activated, receiving and processing the monitoring signals of the upper sensor module and the lower sensor module.
    The device activates the actuation signals of the mast extension mechanism and / or acoustic visual aids, for the extension of the mast, limited to the permissible extension level, calculating the following values
    • the existence of objects in the projected mast extension path,
    • maximum extension length according to design and
    • the maximum user-defined extension level.
    The detection of objects is made from the inputs of the distance sensors. The calculation is updated continuously as the telescopic mast extension is advanced.
    During the mast extension process, the processing mode receives the signals from the upper sensor module and lower sensor module and calculates the balance indicator of the mast at the current mast extension level.
    The mast balance indicator is compared with the predefined mast thresholds in terms of structural safety and prevention against overturning (mast warning threshold and critical mast threshold) activating one of the following action strategies, depending on the result of said comparison:
    • Maximum extension of the mast guaranteeing compliance with safety conditions
    o If the mast balance indicator is below the mast warning threshold and the current mast extension level is below the permissible mast extension level, the device calculates the level of the safe mast extension, understood as the level of extension closer to the level of permissible extension of the mast that ensures compliance with the minimum requirements of structural safety and prevention of the moment of overturning and that is lower than the level of permissible extension of the mast.
    o The permissible mast extension level is calculated as the minimum value of the distance to the nearest object in the mast extension path, the maximum length of the mast according to the design and the maximum extent of the user defined mast . The fact that the distance to the nearest object in the trajectory of the mast is considered in the calculation of the permissible extension level of the mast greatly increases the safety in the process of extension of the mast.
    o The device activates the actuation signals on the mast extension mechanism and / or the visual or acoustic aids for the mast extension.
    o This action strategy allows to reduce significantly the time necessary for the correct deployment of the mast since it assists the operator in charge of the installation during the process.
    o Once the current mast extension level has been modified, the process is restarted by calculating the balance indicator of the mast.

    • Validation of the correct deployment of the mast and definition of the maximum level of extension of the mast
    o If the mast balance indicator is below the mast warning threshold and the current mast extension level is equal to the permissible mast extension level, the current mast extension level is considered correct in terms of structural safety and prevention of the overturning moment, the current level of mast extension is defined as the maximum level of mast extension.
    o The process continues with the next phase of the procedure and activates the ‘Correct mast deployment’ signal.
    • Retraction of the mast to the maximum extension level that ensures compliance with safety conditions
    o If the mast balance indicator is higher than the warning threshold of the mast and below the critical threshold of the mast, it is considered that the current level of mast extension does not meet the minimum requirements in terms of structural safety and prevention of the timing of I overturn.
    o The device calculates the level of safe extension of the mast, understood as the level of extension closest to the current level of extension that ensures compliance with the minimum requirements of structural safety and prevention of the moment of overturning and that is lower than the current level of mast extension and to the permissible mast extension level.
    o This reaction by retracting the mast until a functional and safe mode of operation is found, maintaining stability, maximizes the availability of the lighting service even in adverse conditions.
    o The extension of the mast is modified manually or automatically by means of the mast retraction mechanism (63) so that the extension of the mast is equal to the level of safe extension of the mast. Once the current mast extension level has been modified, the process is restarted by calculating the mast balance indicator at the current mast extension level.
    • Activation of the security alarm status and modification of the installation conditions of the base to maximum security and stability conditions
    o If the balance indicator of the mast is higher than the critical threshold of the mast, it is considered that the current level of extension of the mast carries a critical risk in relation to structural safety and the risk of momentum of the structure overturning. The device activates the security alarm status. the following outputs are activated:
    o The extension of the mast is manually or automatically modified by activating the actuation signals on the retraction mechanism and / or the visual or acoustic outputs so that the extension of the mast is zero, that is the mast is fully retracted .
    o The installation conditions of the base are manually or automatically modified by activating the performance signals on the support elements and / or the visual or acoustic outputs so that the base is in a safe position.
    o The orientation mechanism of the luminaires is modified to minimize the surface facing the wind and to mechanically protect the luminaires. For this, the device activates the actuation signals on the orientation mechanism of the luminaires and / or the visual or acoustic outputs, leaving the luminaires in a safe position.
    o The device is reactivated only when the start button signal is reactivated (20)
    From the point of view of the operation and lighting service, the proposed device and procedure maximizes the availability of the lighting service even in adverse conditions which constitutes an important advantage, due to the fact that in the automatic height adjustment procedure of the mast and of adjustment of the height and pressure on the support elements, the device always seeks to maximize the deployment of the mast in stable operating conditions of the tower.

    In the mast extension process, the permissible extension level is limited taking into account not only design criteria and operation requirement but also depending on the detection of objects in the mast extension path, since, if in the The location of the telescopic tower detects the presence of high voltage cables or other objects such as roofs, articulated arms or elements of machinery located in the surroundings of the tower, the device would detect the presence of this object in the path and, consequently, the extension of the mast so as to avoid a possible collision.
    Phase 4 of monitoring and control of the operating conditions of the telescopic lighting tower
    It starts if the signal ‘Correct base installation’ and the signal ‘Correct mast installation’ are active,
    During the period of use of a telescopic tower, there may be various factors that directly or indirectly affect the structural safety and overturning of the telescopic tower. Therefore, modification of the tower's operating conditions may be necessary.
    The electronic control module continuously receives and processes the signals from the lower sensor module and the upper sensor module for the calculation of the base balance indicator and the mast balance indicator.
    Depending on the result of the comparison of the base balance indicator with its corresponding thresholds and the mast indicator with its corresponding thresholds, one of the following action strategies is activated:
    • Validation of the tower's operating conditions and continuation with monitoring and control
    o If the base balance indicator is lower than the base warning threshold and the mast balance indicator is lower than the mast warning threshold, and the current mast extension level is equal to the maximum extension level of the mast mast, the monitoring and control of the operating conditions of the telescopic lighting tower is continued
    • Maximum extension of the mast guaranteeing compliance with safety conditions
    o If the base balance indicator is lower than the base warning threshold and the mast balance indicator is lower than the mast warning threshold, and the current mast extension level is lower than the maximum extension level of the mast mast, the device calculates the level of safe extension of the mast, understood as the level of extension closest to the maximum level of extension of the mast that ensures compliance with the minimum requirements of structural safety and prevention of the moment of overturning and that is less than permissible level of mast extension.
    o The permissible mast extension level is calculated as the minimum value of the distance to the nearest object in the mast extension path, the maximum length of the mast according to the design and the maximum extent of the user defined mast . The fact that the distance to the nearest object in the trajectory of the mast in the calculation is continuously considered significantly increases the safety in the process of monitoring and controlling the operating conditions of the tower.
    o The device activates the actuation signals on the mast extension mechanism and / or the visual or acoustic aids, for the extension of the telescopic mast, continuing with the monitoring and control of the operating conditions of the tower.
    • Modification of the tower's operating conditions to ensure safe operation of the tower mast
    o If the base balance indicator is lower than the base warning threshold and the mast balance indicator is higher than the mast warning threshold and lower than the critical mast threshold,
    o Firstly, the device defines the action strategy in the support elements of the tower base to indirectly influence the correct installation of the mast. The device activates the outputs for the base support elements and / or the acoustic or visual outputs.

    Advantages of the invention
    The device and procedure of monitoring and control in telescopic lighting towers that is recommended, provides multiple advantages over those currently used, it is noteworthy that with its application the collapse of a lighting tower is avoided, by ensuring the stability of the telescopic tower and not simply act on external causes that could affect stability.
    The incorporation of the device in the telescopic lighting towers object of the invention makes it possible to react by retracting the mast until a functional and safe mode of operation is found, maintaining stability, detecting other conditions that propitiate the collapse of the tower, such as blows machinery, landslide, ground vibrations due to explosions or machinery or mechanical failures of the telescopic tower itself. Since the device reacts actively, it is able to extend the mast again until the permissible extension level is found, once the compromising stability conditions have ceased
    Another advantage, as a consequence of the previous one, is the stability of the telescopic tower that is obtained with the implantation of the device, being possible to maintain a stable position in adverse weather conditions, such as rain, hail, snow and / or ice formation
    Another important advantage is that the stability of the telescopic tower is ensured through an electronic module, in constant communication with at least one lower sensor module, positioned at the base of the telescopic tower and at least one upper sensor module, positioned on the mast, automatically maintaining the equilibrium levels of the base and permissible extension of the mast, depending on the environmental conditions, the physical characteristics of the terrain, the level of inclination or slope of the terrain as well as the conditions of use and handling of the tower, impacts, blows , etc.
    As an added advantage, it can be said that the electronic control module incorporates a signal adaptation mode and a processing mode in which the predefined thresholds or thresholds are included, acting directly on the support elements of the base, retraction mechanisms and mast extension, luminaire orientation and visual or acoustic aids.
    Additionally, the device maximizes the availability of the lighting service even in adverse conditions, due to the fact that in the procedure of automatic adjustment of the mast height and adjustment of the height and pressure on the support elements of the base, the device always seeks to maximize the deployment of the mast in stable operating conditions of the tower.
    As an important advantage, it should be noted that the monitoring and control procedure of the device makes it possible to significantly reduce the time necessary for the correct installation and deployment of the telescopic tower since it assists the operator in charge of the installation during the process.
    In the same sense, it is worth highlighting the advantage that the device monitoring and control procedure significantly increases the safety in the mast extension process since it limits the permissible extension level taking into account not only design criteria and operation requirement but also depending on the detection of objects in the mast extension path.
    Finally and also related to safety, it can be added as an advantage that in the monitoring and control procedure of the device the safety alarm status is activated in case of detecting critical conditions in the mast and / or in the base, proceeding to the absolute retraction of the mast and the modification of the conditions of installation of the base to conditions of maximum security and stability.
