Intelligent Control System of Train Door Logic Based on Intelligent Control Unit

Abstract

An embodiment of the present invention provides a train door logic intelligent control system based on an intelligent control unit, including: a first intelligent control unit located in a selected vehicle, a second intelligent control unit located in other vehicles, and a door controller located in each vehicle After the first intelligent control unit obtains the door control operation information, it outputs the corresponding door control instruction through the corresponding door control instruction output port; the corresponding door control instruction input port of the first intelligent control unit and the second intelligent control unit receives After the door control instruction, drive the corresponding door controller control port to control the door controller of the vehicle to execute the door control instruction. The logic intelligent control system of the train door based on the intelligent control unit provided by the embodiment of the present invention solves the problems of complex logical control circuit of relays of EMUs, abnormal adhesion of contacts, and burning of circuit boards by using a non-contact control system; At the same time, the cost is saved, the circuit is simplified, and the maintenance efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a train door logic intelligent control system based on an intelligent control unit. Background technique [0002] In the EMU door logic control circuit, due to the large number of relays involved, the risk of a single point failure leading to the failure of the entire system is increased. At the same time, due to the large number of involved doors, the vehicle penetration cable structure is more complicated. At present, if it is necessary to modify the logic control of the car door, it is necessary to carry out circuit modification on the basis of the original circuit. This modification may involve the discarding and remanufacturing of the circuit board or the modification of the external wiring. Secondly, for the current structure of vehicle logic control, all printed circuit boards have the risk of burning, and the protection to avoid burning is all concentrated on th...

Problems solved by technology

[0002] In the EMU door logic control circuit, due to the large number of relays involved, the risk of a single point of failure leading to the failure of the entire system is increased. At the same time, due to the large number of involved doors, the vehicle penetration cable structure is more complicated

At present, if it is necessary to carry out the transformation of the door logic control, it is necessary to carry out circuit transformation on the basis of the original circuit. This transformation may involve the discarding and remanufacturing of the circuit board or the modification of the external wiring.

Secondly, for the current structure of vehicle logic control, all printed circuit boards have the risk of burning, and the protection to avoid burning is all concentrated on the side of the circuit breaker. If there is a problem and the circuit breaker trips, there will be a In the case of large-area logic control circuit failure, it is too expensive to protect each circuit with the current technology
