A control circuit and reducer control box of a tw-2 hump system reducer

Abstract

The invention belongs to the technical field of rail transit, and particularly relates to a control circuit of a TW-2 hump system speed reducer and a speed reducer control box. The control circuit comprises a first control circuit and a second control circuit, and the first control circuit is connected with a front-stage speed reducer and a back-stage speed reducer and used for controlling the front-stage speed reducer and the back-stage speed reducer to execute braking or relieving action; and the second control circuit is connected with the front-stage speed reducer, the back-stage speed reducer and the first control circuit and is used as a control loop of the front-stage speed reducer and the back-stage speed reducer so as to realize double control of the speed reducers. The speed reducer control box is installed on an indoor relay combination, the four operations of foreground braking, background braking, foreground relieving and background relieving of a speed reducer are controlled in a centralized mode, meanwhile, negative electricity generated when the speed reducer works is led into a control loop line, and double-break of a power source in the control process is achieved.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to a control circuit of a TW-2 hump system reducer and a reducer control box. Background technique [0002] TW-2 hump automatic control system (referred to as TW-2 system) is an equipment for automatic hump field to realize the automatic control of hump slipping into the road and vehicle speed regulation. The hump vehicle reducer is used as the main control device for automatic speed control of the TW-2 system. Through the "braking" and "relief" control functions of the vehicle reducer, the hook car can reach the target calculation exit speed when leaving the reducer. When the hook car is unloaded from the hump, ensure that the hook car maintains a reasonable distance between the hook car and the car in the unloading area, that is, the hook car is safely connected with the stop car at a speed of 5km / h or less in the shunting line or synchronized with the stop car ...

AI Technical Summary

Problems solved by technology

When implemented on site, the relay occupies a large space, engineering wiring is required between the relay combinations, the construction workload is large, and it is not convenient for on-site maintenance. At the same time, the drive output of the microcomputer is a single-side output, and it is impossible to realize double-break of the power supply in case of failure.
