Abstract

The present invention refers to a system for the remote reactivation and monitoring of an electronic cabinet intended to control the operation of trains. This system prevents a technician from coming to the electronic cabinet for reactivating the same in a manual form, since the system may be reactivated at distance by a computer, which reduces the reactivation time. In addition, the system allows the operation of the voltage sources to be monitored in real time as well as the passivation signal from the electronic cabinet, with which it is possible to know if the passivation signal was originated by a malfunction of the voltage sources, this enabling the technician to repair the fault.

Description

SYSTEM FOR REMOTE REACTIVATION AND MONITORING OF THE CABINET ELECTRICAL CONTROLLING THE TRAIN OPERATION Field of the Invention The present invention is located in the field of systems useful for reactivating and monitoring devices or equipment located at great distances or in places of difficult access. Particularly, this invention refers to a system for remote reactivation and monitoring of the electrical cabinet that controls the operation of trains.

Background of the Invention The SACEM Automatic Piloting System of the Collective Transport System aims to increase safety in the movement of trains, authorizing their departure only when they meet all the necessary safety conditions for driving, in addition to providing an automatic train driving mode in its route using the equipment and devices of the Fixed Installations and the Rolling Stock.

Additionally, the Automatic Pilot system maintains the constant speed of the train regardless of the number of passengers on board, in addition to providing a smooth and precise braking at the normal point of stop of the stations and the signaling located in the interstations. All this respecting the speed and safety limits that Signaling provides throughout the entire STC network.

For this reason it is very important that the SACEM Automatic Pilot system always receives reliable signals from the devices that provide information during its operation, since otherwise the SACEM Automatic Pilot system could base its decision making on incorrect information. that could cause a malfunction in the running of the trains or even cause an accident.

Physically, the Automatic Pilot system is made up of two voltage sources and a set of electronic cards, where the logical operations and the signal processing to the Fixed Installations are carried out, in order to send the control signals to the Rolling Stock. for its correct operation and operation.

Said electronic boards of the SACEM Automatic Pilot system are located inside an "electrical cabinet" or "electrical cabinet" which has a protection signal called "Automatic Pilot Locker Passivation Signal", which prevents the cards of the SACEM Automatic Pilot system perform any function each time this signal is present. This protection system is activated when the cabinet detects a malfunction in the acquisition of data or a low voltage of the voltage sources that supply the cabinet, which is considered one of the main failures of the electrical cabinet.

Once the "Automatic Pilot Locker Passivation" signal is activated, a technician must move from its Permanence to the electrical cabinet to determine the cause of the failure and perform the corresponding repairs. It is worth mentioning that the technician's transfer time can be from 20 minutes to 1 hour and 30 minutes, depending on how far away the electric cabinet is from the activation of the "Automatic Pilot Cabinet Passivation" signal. . The technician usually reassembles the electrical cabinet by manually activating the on / off switch to the off position for a few seconds, then returning it to the on position and thus reactivating the SACEM Automatic Pilot system. This only works when the system detects an abnormal or out of range signal acquisition routine, so if any voltage source is damaged or out of voltage range the technician will necessarily have to replace the damaged source so that the cabinet returns to work correctly.

Summary of the Invention Given the above, an objective of the present invention is to provide a system for remote reactivation and monitoring of the electrical cabinet that controls the operation of trains, which reduces the time of reactivation by allowing it to be done remotely, preventing a technician from having to go to the electrical cabinet and perform this operation manually.

A further objective of the present invention is to provide a system for remote reactivation and monitoring of the electrical cabinet that controls the operation of trains, which facilitates its repair by allowing remote monitoring of the voltage sources that feed the cabinet, determining if these are find in correct operation.

Brief Description of the Figures of the Invention Figure 1 refers to the components that interact in the system for remote reactivation and monitoring of the electrical cabinet that controls the operation of trains.

Detailed description of the invention The elements that interact in the system for the remote reactivation and monitoring of the electrical cabinet (1) that controls the operation of trains, are explained below: An electrical cabinet (1) or also called "electrical cabinet", which controls the operation of trains. Said closet is formed by a metal box that serves as a structure to fix various electical elements inside it. Said electrical cabinet (1) is located inside the technical room, which can be located on the platform or between two stations. It is worth mentioning that there is an electrical cabinet (1) for every two stations.

- - Two voltage sources (2) which provide the electrical for the fixed elements inside the electrical cabinet (1) to work.

A set of electronic boards for automatic train piloting (3), which are fixed inside the electrical cabinet. Said electronic cards contain the program and the electrical components that make possible the operation of the automatic train piloting system (SACEM).

An on / off switch (4), which is fixed to the inside of the electrical cabinet (1) and serves to turn it on or off.

A digital remote reactivation and monitoring card (5), which contains the program and the electrical components that make possible the operation of the remote reactivation system and monitoring of the electrical cabinet (1). This card has the following voltage inputs: 1. Supply voltage of the circuit 12 VDC 2. 56 VDC voltage source 3. 72 VDC voltage source 4. Passivation signal 24 VDC 5. Supply voltage of the electrical cabinet (220 VAC) It also has a voltage output to send the reactivation signal to the on / off switch (4) of the - - electrical cabinet (1). This output is called "relay" and provides a voltage of 12 VDC for the activation of said switch. This digital remote reactivation and monitoring card (5) is fixed to the back of the cabinet.

A computer equipment (6), which can be any computer equipment connected to the internal network of the meter (intranet), which serves to monitor and send reactivation signals through a graphical interface. Where you can know in real time if a passivation signal has been generated from the electrical cabinet. Said computer equipment (6) can be located in any place where there is an intranet connection, such as an office or a monitoring center.

The aforementioned elements are connected to each other by means of cables as indicated in figure 1.

The system for remote reactivation and monitoring of the electrical cabinet (1) that controls the operation of trains, allows to monitor in real time the "passivation of electrical cabinet" signal and the state in which the voltage sources are located (2) that feed him.

The "electrical cabinet passivation" signal or "standby" is a protection signal of the electrical cabinet (1) which prevents all the electronic cards in its interior from performing any function, among which is the digital card of automatic train piloting (3). This protection system is activated when the electrical cabinet (1) detects a malfunction of the voltage sources (2) or when the microprocessor of the digital card of the automatic pilot system (3) becomes saturated with operations. In addition, the malfunction of said voltage sources is one of the main causes by which the passivation signal originates.

The electrical cabinet passivation signal is detected by the digital remote reactivation and monitoring card (5). Said information is transmitted from said card to the computer equipment (6), where said information is displayed to the technician by means of a graphical interface, informing the latter in real time if the passivation is activated or deactivated.

The operating status of the voltage sources (2) is also detected in the same way by the digital remote reactivation and monitoring card (5). Said information is also transmitted from said card to the computer equipment (6), where said information is displayed to the technician through a graphical interface, informing the latter in real time if one or both sources are in operation.

Based on the information provided by the computer equipment (6), the technician can make the decision to send a "reactivation of the closet" signal, which is transmitted from the computer equipment (6) to the digital reactivation card remote control and monitoring (5), which in turn sends a signal to the on / off switch (4) that causes it to turn off and turn on electronically, which causes a "reset" of the electrical cabinet (1).
