    System and method of checking brakes TECHNICAL SECTOR
    The present invention relates to a system and method of checking the brake of the different cars of a train or convoy. It is applicable in the railway and safety field.
    STATE OF THE TECHNIQUE
    Within the maintenance and prevention tasks in trains or railway convoys there is a need to check the different brakes of the wagons, usually pneumatic, to ensure proper braking. For this there is a protocol that includes data collection of the system pressure at critical points of each car and in different situations or scenarios. Two people are required to perform this task. One that will be in the cabin to operate the controls and another in the lower part of the train taking pressure at the critical points. This procedure is relatively long, and with complicated sound conditions for the person taking the pressure, as the train must be running. This implies health and safety problems, as well as a risk of poor communication between both people that invalidates the measures taken.
    BRIEF EXPLANATION OF THE INVENTION
    The invention consists of a system and a method of checking brakes, applicable to the different cars of a train, according to the claims.
    This system introduces substantial improvements with respect to the "manual" realization that was being carried out to date. In the first place it comprises a great improvement of the conditions for carrying out the test for the personnel that executes it. In addition, it allows analyzing at the same time all brake systems, so the final operating time is greatly reduced, as well as the time the train needs to be in operation, with the consequent energy savings.

    In addition, the coordination between the different units of the system by the wireless transmission ensures that there is no temporary lag, since all measurements are taken at the same time and in the same position of brake activation. This advantage is especially notable when performing the evaluation measurement of the rise and fall of pressure in the automatic brake line (TFA). Since the rise and fall is very fast (less than three seconds), a small lag in the measurement produces large errors. Another procedure that benefits from coordination is the measurement of times in the loading and unloading of the brake cylinders. In the manual method, the need to transmit the measurement moments orally (even by radio) reduced the reliability of the measurements.
    The coordination of measures also allows checking in parallel all the control points of each car, checking that the brake response is supportive and coherent.
    Finally, the electronic measurement can increase these, for example, by refreshing at 10 Hz.
    The brake check system is of the type applicable to trains or convoys of wagons, and comprises one or more capture units with two brake circuit pressure detectors attachable at the respective control points. The capture units will also have two wireless transmitters. The system also includes a management unit with a second wireless transmitter for receiving the measurements of the capture units and a memory for measuring the measurements, such as a computer connected to the management unit to perform the dump in real time .
    Preferably, the wireless transmitters have the function of repeaters to allow the correct reception of the signals of the furthest capture units, since in transport trains it may involve a distance of several hundred meters.
    In a preferred embodiment, the pressure detectors are pressure transducers.
    For its part, the brake check method takes advantage of the system mentioned and consists of the stages of:

    - Place one or more capture units with pressure detectors at the control points of the train or car.
    - Place the management unit in the cabin;
    - Establish wireless communication between the capture units and the management unit.
    - Perform the operations of the test protocol to practice.
    - Send in parallel the pressure measurements from each capture unit to the management unit that associates the measure with the operation performed.
    DESCRIPTION OF THE DRAWINGS
    For a better understanding of the invention, Figure 1 is included, where a basic scheme of a preferred embodiment example is shown.
    EMBODIMENTS OF THE INVENTION
    Next, an embodiment of the invention will be briefly described as an illustrative and non-limiting example thereof.
    The invention allows the performance of the task by a single person, who may be conveniently protected from sound hazards. For this, it uses wireless technology arranged in a series of capture units (1), usually with autonomous power supply to simplify installation. The capture units (1) will be arranged at each of the points (P) to be controlled and will emit their pressure reading. The capture units (1) will be installed at the beginning of the test, either in all or part of the cars and their number will depend on the points (P) measured, for example three in each car.
    The capture units (1) transmit their reading to a management unit (2) arranged in the train cabin, either odd or even, comprising a microprocessor or connected to a computer (3).
    A program or application on the computer (3) will indicate the tasks to be performed to carry out the test protocol and capture the readings received by the management unit (2) to detect any abnormal value (which can be previously defined according to the train characteristics). For this, it is preferred to carry out the application with

    a software like LabVIEW where a sequence of screens will be designed that will allow, along with a basic training, to perform the required tests. It is possible to arrange for the management unit (2) to give the appropriate commands to the cockpit controls if it admits this type of control. This avoids operator intervention, increasing reliability, as well as allowing the management unit (2) the exact moment at which each phase of the protocol begins.
    Each capture unit (1) will have a pressure detector (10) such as a pressure transducer, and a wireless transmitter (11) that sends the measurements to the management unit (2), together with an identification from the capture unit (1) and preferably the exact time (accuracy of up to tenths of a second or greater) and receive any order from the management unit (2). With a view to greater stability in taking readings using the 4-20 mA system, it is preferred to transform the reading into current. This current is transformed by an adapter into a voltage input that is what the X-Bee module (version 2.5) can read, which corresponds to the preferred wireless transmitter as it includes repeater functions that repeats the signals of the capture units (1 ) further away.
    The management unit (2) on the other hand comprises a display screen, which will generally be that of the computer itself (3), and a second wireless transmitter (21) similar to the previous ones although it will not need to perform the repeater functions. The management unit (2) or the computer (3) indicates to the operator the sequence of operations to be performed to carry out a brake protocol. In each of the operations carried out, the pressures reached and the time it takes to reach certain levels are automatically controlled. If all parameters are within the tolerances determined in each case, both in pressure and in time, the operations performed are given as correct and thus indicated to the operator.
    If all the operations included in the protocol have been indicated as correct, a protocol is automatically issued indicating the values obtained for pressure or time.
    In the event that the result of any step has been incorrect, the protocol is not performed and instead the operator is indicated the erroneous operations and the values that have not entered the established tolerance range, with this information they have to be regulated the teams that have not met the established values and once
    These adjusted and corrected deviations must pass the protocol tests in their entirety.
    The system can be complemented with a calibrator (not shown) formed by a pipe that comprises a socket for each capture unit (1) to be calibrated, a power outlet and a socket for a precision manometer, so that when feeding by the power outlet, the capture units (1) can be calibrated from the manometer reading.
    10 The method of operation consists of the stages of:
    - Place one or more capture units (1) at the control points (P) of the train or wagon.
    - Place the management unit (2) in the cabin.
    - Establish communication between the capture units (1) and the communication unit
    15 management (2)
    - Perform the operations in braking cab, brake release, etc. as dictated by the protocol of tests to practice.
    - Send in parallel the measurements from each capture unit (1) to the management unit (2) that associates the measure with the operation performed.
