Problems solved by technology

Finally, this method makes it possible to detect failures up to electromagnets by comparing the read state with the commanded state, but rarely detects failures of contactors and therefore lacks reliability

Embodiment Construction

[0040] As an example, figure 1 A device for dynamically controlling the safe adjustment of the binary switching states of at least one electrical switching system (12) integrated into an automation device (1), said switching system (12) being driven by means of a drive circuit (13) at least an actuator (2). The equipment includes:

[0041] - a command module (11a) which in particular commands the state of the electrical switching system by means of a state command (15),

[0042] - a reading device (14) capable of reading the switching state of the electrical switching system (12) and transmitting to the control module (11b) a control signal (Sc ),

[0043] It is characterized in that the reading device (14) is arranged downstream of the electrical switching system (12) and is connected to the drive circuit (13) of the actuator (2). In particular, said connection enabling reading (16) may comprise at least one transformer as isolation means and an opto-isolator as read mean...

Abstract

The invention relates to a method and a device for dynamically controlling the secure adjustment of a binary switching state of at least one electric switching system built into an automatically functioning apparatus used in the field of guided vehicles, said switching system driving at least one actuator by means of a driving circuit. The device includes: a control module controlling the state of the electric switching system, and a reading device capable of reading the switching state of the electric switching system and of transmitting a control signal related to the read switching state to a monitoring module. The device is characterised in that the reading device is provided downstream from the electric switching system and is coupled to the driving circuit of the actuator, thereby providing the automatically functioning apparatus with enhanced reliability and maintainability.

Description

technical field [0001] The invention relates to a method according to the preambles of claims 1 and 10 for dynamically controlling a safe (ie more robust) adjustment of the (eg open or closed) binary switch state of at least one electrical switching system and equipment. [0002] In particular, the invention relates to the reliability and maintainability of electrical switching systems integrated into automation equipment in the field of guided vehicles, for example in the field of railways, by means of the delivery of separate switching off of the switches of the switching system. A circuit de pilotage of a state-dependent digital output to drive at least one actuator. Background technique [0003] In particular, the term "guide vehicle" refers to public transport means, such as buses, trolleybuses, trams, subways, trains or train units, etc., for which safety aspects are of great importance. This safety aspect is particularly relevant for the correct functioning of autom...
