Electric motor coach gate control external circuit with two-side gate opening and closing control function

Abstract

The invention discloses an electric motor coach gate control external circuit with the two-side gate opening and closing control function. The electric motor coach gate control external circuit comprises a driver controller, a gate control circuit, a gate controller, an end switching gate control circuit, a zero-speed signal unit and a coach gate safety loop wire. The driver controller is connected with the gate control circuit through a key switch in series, the gate control circuit is connected with the gate controller and provides opening and closing signals for the gate controller, the end switching gate control circuit is connected with the gate controller and provides input signals for switches of coach gates on the two sides, the gate controller is interlocked with the zero-speed signal unit, the coach gate safety loop wire is interlocked with a traction circuit, and the end switching gate control circuit can have the manual end switching function. The electric motor coach gate control external circuit has the advantages that the gate control circuit is interlocked with a key of the driver controller, so that the safe operating level is increased; the gate controller is interlocked with the zero-speed signal unit, and the coach gate safety loop wire is built, so that personal safety of passengers can be guaranteed, the coach gates on the two sides of a coach can be simultaneously opened, manual end switching of the coach is achieved, and flexibility and variety of end switching of the coach and operating efficiency of the coach are improved.

[0002] As an important means of rail transportation in modern times, electric passenger cars have increasingly become a solution to traffic congestion in major cities, and transporting passengers to their destinations safely and smoothly has become its main task. At present, in the design of electric passenger cars, the door control circuit It is one of the most important links related to driving safety. During operation, the safe and effective control of the door is one of the important factors to ensure the large passenger capacity of the electric bus. The failure of the door control of the bus can lead to the delay of the running time of the vehicle. , more seriously, can directly threaten the lives of passengers, therefore, it is particularly important to design a safe and reliable door control circuit

[0003] At this stage, the control of the passenger car door is that after the electric passenger car is parked stably, the driver manually or through the signal system equipment sends the door open enable signal of the left door or the right door to the door controller, and then sends the door opener to the door controller. The command signal for opening the left door or opening the right door can only send out one door opening enable signal, that is, within the same time period, only the left door or the right door can be opened, and it is impossible to open both doors at the same time; In the case of ATP (Automatic Train Protection) protection, although the products of some signal equipment suppliers can force two door opening signals by pressing the "forced door opening" button, when the driver gives a After the door opening and closing command, the door opening enable signal of the unopened side will be canceled, and the simultaneous opening of both doors cannot be realized.
