Definitions
- Method and device for controlling a setting of a switching state of an electrical switching system related to the guide of guided vehicles are described.
- the present invention relates to a method and a device for dynamically controlling a secure, ie safer, setting of a binary switching state, for example open or closed, of at least one electrical switching system, according to the preambles of claims 1 and 10.
- the invention relates to the reliability and maintainability of electrical switching systems integrated with automation equipment related to the field of guided vehicles (for example, the railway domain), said electrical switching system driving at least an actuator by means of a control circuit delivering an on / off output relating to the respectively open or closed switching state of the switching system.
- guided vehicles refers in particular to means of public transport such as buses, trolleybuses, trams, subways, trains or train units, etc., for which the security aspect is very important.
- This safety aspect is particularly related to the proper functioning of automation equipment internal or external to the vehicle.
- Examples of internal and external automatic control equipment are the automatic closing of the doors of a train and, respectively, the control of switching of a subway.
- vehicle and / or the movement of other vehicles for example, obstruction of other vehicles due to a technical failure of the automation equipment).
- the switching system is in an open state while it is controlled in a closed state
- the switching system is in a closed state when it is controlled in an open state.
- the electromechanical relay is a particular electrical switching system, consisting mainly of an electromagnet for mechanical contact by displacement of a moving part called the contactor, an upstream electrical circuit and a downstream electrical circuit.
- the contactor is provided with a main contact and an auxiliary contact, the main contact serving to control the actuator and the auxiliary contact to read the state of the relay.
- this method only applies to the particular case of electromechanical relays and is not applicable, for example, to a static relay, for which an auxiliary contact is no longer possible.
- a major disadvantage of this method is that it only works if the auxiliary contact is in the same state as the main contact, which is not always the case with an ordinary relay, especially during a failure bonding type, and therefore requires the use of special relays with integral and non-overlapping contacts, one of which is used to control the actuator, and the other is looped back to the control module.
- the method does not cover with certainty glue failures.
- this method makes it possible, by comparing the state read with the commanded state, to detect faults up to the electromagnet, but very rarely makes it possible to detect a failure of the contactor, hence a lack of reliability.
- An object of the present invention is to propose a reliable dynamic control method for the secure setting of a binary open or closed switching state of at least one electrical switching system integrated with automation equipment related to the field of vehicles guided and driving at least one actuator, in order to secure the switching system and to improve the reliability and maintainability of the automation equipment.

- the method according to the invention is characterized in that the reading is performed by coupling the control circuit with at least one transformer as an isolation component.
- the transformer can advantageously be miniaturized in order to occupy a small space in the automation equipment and moreover, it guarantees a good electrical insulation so as not to disturb the operation of the actuator and not to alter the electrical characteristics of the all or nothing output.
- the transformer may advantageously provide a power supply allowing an optocoupling reading to the control circuit.
- the optocoupling takes place only when the switching system is closed, thus allowing the transmission of a control signal correlated to the closed state of the switching system to the control module.
- the optocoupling does not take place, allowing the transmission of a read signal correlated to the open state of the switching system.
- the optocoupling thus guarantees the transmission of two different control signals depending on whether the switching system is open or closed.
- the binary characteristic of the state of the switching system is thus retranscribed in the control signal via the optocoupling.
- the method according to the invention is further characterized in that the reading is performed by current measurement or impedance measurement via the transformer.
- the reading and the electrical insulation are performed by a single component, the transformer, which not only saves space, but also costs.
- the method according to the invention is also characterized in particular by the fact that said control module is able to compare the controlled state with the read state and to signal a divergence between the read state and the commanded state, said divergence being the characteristic of a probable failure.

This may be for example the remote control by a train of the correct routing of a channel, but also, a remote transmission of information concerning the opening / closing of doors, the transmission of said information can for example, to be linked to a vehicle start-up condition.
- a remote control of the control and control modules makes it possible to exchange information concerning the switching state of the switching system.

- Another advantage of using an optocoupler is to be able to isolate, from a galvanic point of view, an electronics linked to the reading device of an electronics linked to the control circuit.
- the transformer can be advantageously used to deliver a signal adapted to the reading of the switching state by current measurement or by impedance measurement.
- the transformer is not only used as a galvanic insulator, but also as a switch state reader, ensuring, by its dual function of insulating component and reading component, a small space requirement of the automation equipment .
- the device is characterized in that the control module comprises a state comparator comparing the state controlled to read state able to signal and transmit information relating to a divergence between the commanded state and the read status.
- This comparison between the commanded state and the actually executed state ie the read state
- control module comprises an intelligent circuit, such as, for example and non-exhaustively, a microprocessor, an FPGA component (ie an array of programmable gates In situ or Field Programmable Gate Array in English), or else an ASIC (ie a specialized integrated circuit or Application-Specific Integrated Circuit in English), it is then possible to multiplex the signals coming out of several (at least two) reading devices and to have a single comparator, this to save space and allow a small footprint by reducing the number of comparators.
