Motor controller for track traffic platform gate

Abstract

The invention relates to a motor controller for a track traffic platform gate. The motor controller comprises a power supply part, a digital signal processing part, an electric current sampling part, a motor driving part, a relay output part, an external control signal input part and a data storage display part; the power supply part is used for respectively supplying electric currents of needed voltages to the digital signal processing part, the electric current sampling part, the motor driving part, the relay output part and the data storage display part; the electric current sampling part, the motor driving part, the relay output part, the external control signal input part and the data storage display part are respectively connected with the digital signal processing part through electrical signals; the motor driving part is also connected with a motor through an electric wire; and the relay output part is also connected with an upper computer through the electrical signals. The motor controller has the advantages of safety, reliability, strong driving capability, wide application, accurate control, stable running, low cost and the like.

Description

technical field [0001] The invention relates to a motor controller, in particular to a motor controller for a rail transit platform door. Background technique [0002] At present, the average daily passenger flow of Shanghai rail transit has reached 6 million passengers. After the rail transit skeleton network is completed, the average daily passenger flow will exceed 10 million passengers. The huge passenger flow has also brought prominent safety hazards. For example, due to congestion, passengers fall off the platform while waiting for the train, passengers enter the track section to pick up objects, passengers fall into the track section due to competition for seats or rushing to time, etc. In response to this situation, it has become a top priority to install rail transit platform doors to properly isolate passengers from trains and track areas, and to prevent casualties. [0003] The main technical difficulties in implementation are: [0004] 1. Automatically adapt to...

[0007] 4. In the final door closing stage, the kinetic energy within the last 100mm stroke range of each movable door is less than or equal to 1J, that is, the door must be closed with a very light force, and the door must be closed reliably. The two form a contradiction, and the 1J The kinetic energy and the running speed of the door also form a contradiction
