    AUTONOMOUS SIGNALING AND EMERGENCY DEVICE AND SYSTEM WITH WIRELESS DATA TRANSMISSION CAPACITY, AND ASSOCIATED PROCEDURE
    FIELD OF THE INVENTION
    The present invention is framed in the field of signaling and warning technologies in emergency situations. More specifically, the object of the invention relates to multimodal and / or multichannel signaling devices configured with wireless connectivity, with the aim of facilitating their maintenance or technical revision in the place where they are installed.
    The present invention has preferential application in the field of signaling in buildings and surfaces, alarm systems, risk and accident prevention, and emergency management. However, the device object of the invention is also valid for other multimodal signaling applications (for example, traffic, signage, advertising, etc.) that can benefit from maintenance and / or remote review processes and their capacity of energy autonomy.
    BACKGROUND OF THE INVENTION
    At present, various signaling and emergency systems based on visual, sound or haptic (tactile) media are known. Such systems usually combine non-electronic signaling means, such as for example printed signs or Braille signage, and electronic signaling means, such as LED lighting ("Light EmiUing Diode"), public address, buzzers, etc. These electronic means also require power supplies to keep their functionalities active, usually being possible to connect to the mains, batteries, solar power sources, etc.
    In the case of electronic signaling systems, interconnected networks of signaling devices are also known, the management of which is supervised by a remote control means, equipped with adequate hardware and software to monitor the operating status of said devices, as well. as to detect possible breakdowns or their maintenance status. However, establishing a network of devices of this type is technically complex and also requires a specific technical infrastructure, adapted to the location where said network is installed (for example, a shopping center, official or office buildings, hospitals, etc. .). The alternative to network facilities is, traditionally, the installation of the devices autonomously, whose maintenance requires the periodic inspection of each of them manually. This consumes, in the case of large installation areas (for example, industrial complexes, department stores, etc.), a large amount of time and resources. The manual control also implies a greater risk of human error during the collection of review data of the individual equipment.
    As a possible solution to this technical problem, US patent application US 2014/0340222 A1 refers to emergency signaling devices (also referred to as "first response" devices), intended to be integrated into a network emergency system preferably arranged in buildings Such devices may include a plurality of sensors equipped with means for collecting dalas from their surroundings (for example, the presence of smoke in case of fire) and deploying, in case of emergency, light and acoustic signaling means.
    Regarding the inspection or maintenance services of the emergency system, US 2014/0340222 A1 describes that, through processing means included in different nodes of the device network, it is possible to record the operating parameters of the same, with the desired periodicity. In case of error or inspection need, the system can generate maintenance alarm signals and send them to the network, for example in the form of email or SMS ("Short Messaging Service").
    For its part, US patent application US 2014/0253328 A 1 refers to a hazard warning device, which can operate independently or in combination with security cameras, and that allows to detect situations of risk or emergency and that It also includes means of communication to provide dynamic hazard warnings and related specific information. More specifically, the embodiments described in US 2014/0253328 A1 are intended to provide audible signaling or visual hazard warnings. As an example, said device can be used to provide an exit route for a building during an emergency, facilitate disaster recovery and rescue operations, or in the field of security.
    Although the previous examples illustrate, respectively, different proposals for networked or individual signaling devices with wireless data transmission capacity for maintenance, all of them depend, ultimately, on an electrical network or battery outlet for operation. . This makes them less reliable in case of power failure, or as time passes and it approaches the end of the life of the batteries used.
    As an alternative to these systems, Spanish patent application ES 2442067 A 1 discloses an intelligent emergency signaling system intended for use in tunnels, comprising a wireless network of devices with meshed topology and fed through an electrical supply system autonomous based on long-lasting batteries. The system is independent of the rest of the devices installed in a tunnel, not interfering with its behavior, and incorporates control, signaling and router devices, generating messages comprising several sensitive, visual, sound, and tactile channels.
    Although these devices can operate for extended periods of time without their batteries running out, they still lack a genuine autonomous energy management capability, which is automatically configured according to the circumstances, without the need for external control. This is, in this area, very desirable for application to facilities such as department stores (where there may be the order of hundreds of devices), since it allows you to optimize your inspection and maintenance processes, without having to resort to expensive computer networks to carry out the same, and without relying on power to the mains or batteries, requiring them to maintain more frequency and complexity.
    In addition, it is also necessary, in the aforementioned technical field, to improve the effective range of the signaling systems used, so that their signals reach as many reception points as possible (for example, customers of a department store, assistants to a show, etc.), thus improving the efficiency of these systems, and therefore also the safety of its users.
    The present invention is aimed at solving the aforementioned needs, by means of a novel autonomous signaling and emergency device with wireless data transmission capability, which resolves the limitations of known systems.

    In another preferred embodiment of the invention, the process module comprises means for conditioning the voltage levels with respect to the connections with the power module and with the signaling module.
    A second object of the present invention relates to an autonomous signaling and emergency system with wireless data transmission capability, comprising two or more devices according to any of the embodiments described herein. Preferably, at least two of said devices are
    they find interconnected forming a network. Also, the system may comprise,additionally, one or more computing means connected wirelessly toSignaling devicesIn a preferred embodiment of the system of the invention, the computing meansThey comprise a mobile phone, a tablet device, and / or a computer.
    A third object of the present invention relates to a signaling and emergency procedure with wireless data transmission capability, which makes use of a device according to any of the embodiments described herein, and which comprises performing the following steps by the process module:
    - The energy level in the secondary energy accumulator sub-module is periodically monitored and, when it reaches a first predetermined value, called the upper threshold, it will activate the energy conditioning sub-module to transfer the energy from said accumulator sub-module of secondary energy to the primary energy accumulator sub-module, until the energy level of said secondary accumulator sub-module drops to a second predetermined value, referred to as a lower threshold.
    - The tasks to be performed by the signaling module are segmented into a plurality of sub-tasks, so that the energy required for its performance is also segmented and where, between sub-task and sub-task, the process module It works in a low power mode, waiting until you have enough power to execute the next sub-task.
    Within the scope of the present invention, the expression "comprises" is to be interpreted, when applied to the relationship between a main element with respect to other secondary elements, such as that said main element includes or contains said secondary elements, but without exclusion of others additional items
    As described, the invention thus involves a novel signaling device specially designed to indicate locations of interest or emergency within a building, such as the locations of emergency exits, stairs, elevators, fire extinguisher installation points. or hoses, etc. As one of its main advantages, the device of the invention has wireless connection means for receiving or sending information to one or more remote terminals. Said terminals may be commercial devices for generic use (for example, mobile devices such as smartphone, tablet, laptop, etc.), or other equipment of specific design, which have wireless connectivity with the signaling device of the invention.
    Thus, the device of the invention can generate unique signaling and emergency messages, to transmit signaling, emergency, alarm, etc. information to the terminals. This allows to extend the radius of action of the device not only to those who are in visual or audible contact with the device itself, but also to the radio reception of the mobile terminals in the vicinity of the same.
    The content of the messages sent by the device is preferably transmitted through several communication channels, with different "humanreadable" (interpretable by human beings) and / or "machine to machine" (device to device messages) encodings. In particular, at least one of these channels will transmit the messages via wireless communication, to the electronic terminals in the vicinity of the signal.
    As described, constructively the device will preferably be energetically autonomous (it can capture the necessary energy from the environment -electricity, light, temperature, etc.-) so that it can always remain operational. For this, it will have for example bias recharge batteries, photovoltaic power supplies, or equivalent means, managed by the power module and the processor for the optimization of its performance and useful life.
    The proposed invention makes it possible to extend, thanks to the issuance of messages through its communications channel and its energy management modules, the concept of traditional signaling, improving the capabilities of known devices in at least three aspects:
    1) Improvement of the signaling service: the content of the messages generated, specifically the content of the signal (for example "emergency exit") and its position (for example "fourth floor"), allows an electronic device to read the message (for example a mobile phone) provide information accessible to users (for example, a blind person who cannot see the broadcast signals).
    2) Improvement of the life and performance of the device: the processor module and the power module of the device allow to efficiently manage the periods of activity and rest of the device, making its useful life increase substantially compared to known devices , giving it greater autonomy. This allows reducing the frequency of replacement or revision of its power supplies.
    3) Improvement of the maintenance service: the content of the message, specifically its identification, location and instant of installation, allows technical personnel to perform the scheduled maintenance procedures more efficiently (for example, checking that the signaling is in accordance with the evacuation plans of the building). Thanks to the communication channel of the device, the device can wirelessly send control records to the review staff, which speeds up and improves maintenance procedures.

    Detailed description of the invention
    A detailed description of the invention, referring to a preferred embodiment thereof based on Figures 1-3 of this document, is set forth below.
    As shown in Figure 1, the present invention relates to a device that essentially comprises three functional modules connected to each other:
    10 Signaling module (1): Includes one or more channels (2, 3, 4) equipped with visual, auditory and / or haptic signaling means. The visual channel (2) can comprise, for example, text and / or images with information (for example "emergency exit"), as well as elements of indication or light signaling, such as illuminated text, flickering signals, bursts, signaling visible in the dark, etc. For its part, the
    The auditory channel (3) may include any sound signaling means, such as public address, reproduction of pre-recorded messages, etc. Finally, the haptic channel (4) can comprise text or overwritten shapes in a superscript, such as Braille text.
    The signaling module (1) additionally comprises a communication channel
    (5) equipped with wireless data transmission and reception means, said means being able to comprise communication in the infrared, radio frequency bands (for example according to the Bluetooth standard, WiFi, etc.) and / or ultrasound. The main function of
    communications channel (5) is to provide connectivity to the device, so that it can communicate remotely with other devices such as mobile terminals, tablets or other equipment configured with transmission / reception means for this purpose. Thus, the communication channel (5) can transmit alert or emergency messages to said equipment, so that it is not necessary to be in the vicinity of the device to receive information from the visual (2), auditory (3) and / or haptic (4), but it arrives directly to the teams involved. Also, the communications channel (5) serves as a means of auditing the operation of the device during its review and maintenance procedures. In this way, the technical personnel can receive, when they move around the vicinity of the device, messages that include, for example, the device identifier, a report of incidents or events, location data, time since installation and last revision, occurrence of breakdowns, etc. This eliminates most visual inspection tasks during maintenance, which greatly simplifies review times when a location has a large number of signaling devices (such as department stores, or industrial plants).
    Also, in a preferred embodiment of the invention, the signaling module (1) comprises one or more sensors for detecting smoke, fire or chemical agents.
    Power module l6l: This module (see Figures 1 and 2) is responsible for providing power to the other components of the device, through various elements that also optimize the management of the energy provided. Said elements preferably comprise:
    A sub-module for collecting energy (7) from the environment, comprising one or more transducers (8) depending on the energy available in the environment of the device (for example, photovoltaic, thermal, kinetic, etc.). This energy is transferred to the device for its accumulation and subsequent use, during the performance of the signaling and communications functions by the signaling module (1).
    A secondary energy accumulator sub-module (9), connected to the collection sub-module (7), intended to accumulate the energy generated by the transducers
    (8) for later use by the different components of the device. Preferably, said secondary accumulator sub-module (9) will be a low loss element by self-discharge, and will not require a high energy storage capacity of the order of hundreds of microfarads. Typically, it will comprise a capacitor, a supercapacitor or an electrochemical capacitor (pseudocapacitor), such as an aluminum or tantalum condenser, or a graphene or niobium based supercapacitor.
    An energy conditioning sub-module (10), connected to the secondary accumulator sub-module (9) that acts as a means of controlling and regulating the energy level of said sub-module (10). Preferably, the conditioner (10) comprises an energy multiplexer (11) configured to transfer energy from the secondary accumulator sub-module (9), to a primary energy accumulator sub module (12) (see below).
    A primary energy accumulator sub-module (12), connected to the power conditioning sub-module (10), and equipped with energy accumulation means of a capacity greater than that of the secondary energy accumulator sub-module (9). Typically, the primary accumulator sub-module (12) comprises a capacitor, a supercapacitor, an electrochemical capacitor, a thin film battery, a flexible battery or a rechargeable battery, for example a lithium battery.
    Preferably, the sub-modules (7, 9, 10, 12) included in the power module (6) will be integrated into the device by means of embedded components, flexible and adaptable to the size of the signaling module (1), so that they do not imply a substantial increase in the volume of said module (1).
    Process module (13): This module (Figures 1 and 2) is connected to the power module (6) (specifically, to the secondary (9) and main accumulator sub-modules (12) and to the conditioning sub-module ( 10) energy), and is also connected to the signaling module (1). It comprises, thus, electronics configured to measure the energy levels of the secondary (9) and main (12) accumulator sub-modules, to control the operation of the conditioning sub-module (10) during the load transfer between the two, and to manage the efficient transfer of energy from the power module (6) to the signaling module (1), and to the process module itself (13).
    The process module (13) preferably comprises integrated electronic components of specific purpose, or discrete components configured to perform the multiplexing operations of the energy sources, accumulators and loads, defined according to one or more pre-programmed sequences. Depending on the components selected as the power source in the power module (6), as well as the specific electronics of the accumulator sub-modules (9, 12) and the process module (13), it is also possible, in a further embodiment of the invention, that the multiplexer
    (11) also comprises means for conditioning the voltage levels with respect to the connections with said elements.
    As mentioned, a second object of the invention also relates to an autonomous signaling and emergency system with wireless data transmission capability, comprising two or more devices according to any of the embodiments described herein where, preferably, said devices are interconnected forming a network. Said network may additionally include one or more computing means connected wirelessly to the signaling devices of the invention, wherein said means may comprise, for example, a mobile phone, a tablet device, a computer and similar equipment, provided that they are provided with the corresponding connection capacity.
    Finally, a third object of the invention relates to a signaling and emergency procedure with wireless data transmission capability, which makes use of a device or system according to any of the examples described herein, and where its main stages are control and execute by the process module (13), sending operating instructions to the rest of the components to which it is connected.
    A preferred embodiment of said process is described schematically in Figure 3. It shows how the process module (13) periodically monitors the energy level in the secondary energy accumulator sub-module (9) and, when it reaches a first predetermined value, referred to as the upper threshold, it will activate the energy conditioning sub-module (10) (for example, through the energy multiplexer (11 ») to transfer the energy from said energy accumulator sub-module (9) secondary to the primary energy accumulator sub-module (12), until the energy level of said secondary accumulator sub-module (9)
    go down to a second predetermined value, called as lower threshold.
    Thus, the described procedure is based on segmenting the tasks to be performed by the signaling module (1) into sub-tasks, such that the required energy 5 is also segmented and, consequently, is optimized. Between sub-task and sub-task, the process module (13) will work in low-power mode, waiting until there is enough power to execute the next sub-task. This has a great advantage, since the amount of energy to accumulate is, therefore, smaller, which results in lower volume and cost of electronics, as well as smaller module size.
    10 power supply (6) (for example, it would imply less surface area of the photovoltaic panel to be used).
    In addition, since the energy used in the execution of each sub-task is stored in a capacitor that is discharged to a minimum operating value, the total power required to execute the operation of the device will be lower. This is due to the fact that the a priori decrease in performance caused by segmentation due to the need to store information between sub-tasks in memory is compensated by the increase in performance due to the module's low consumption processes of process (1 3). Said module will thus execute the functions that are possible according to the energy accumulated in the secondary energy accumulator sub-module (9),
    20 as long as it exceeds the predetermined lower threshold value.
