Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] The structure of the driver's controller of the present invention's own redundant function, as Figure 1 to Figure 5 As shown, it includes a reversing unit 2 , a traction braking unit 3 and a redundant unit 4 arranged on a mounting plate 1 .

[0025]The reversing unit 2 includes a reversing upper plate 5 arranged on the lower end surface of the mounting plate 1. The upper end surface of the reversing upper plate 5 is fixed with a reversing seat 6 protruding from the mounting plate 1 by fasteners. The rotating reversing handle 7, the lower end surface of the reversing upper plate 5 are fixed side by side by the fasteners on the reversing switch frame 8 and one end of the reversing fixed column 9, and the other ends of the reversing switch frame 8 and the reversing fixed column 9 pass through the fasteners The reversing lower plate 10 i...

Abstract

The invention discloses a driver controller with redundant functions, which comprises a reversing unit, a traction brake unit and a redundant unit arranged on a mounting plate. The redundant design adopts an independent mechanical interlock and transmission structure, which solves the problem of single redundant mode in the driver controller of rail transit rolling stock, and integrates the redundant signal output function and redundant signal switching function into the driver controller. The redundant design adopts an independent mechanical interlock and transmission structure, which avoids the potential risk of failure of the redundant function due to the use of a mechanical structure for the main and redundant functions, and realizes that the redundant function can be completed without cooperation with external components. I switch. The redundant switch operation interface and the redundant output operation interface are integrated into the redundant unit and combined into a redundant traction brake handle, which reduces the design space required to realize redundant functions.

Description

technical field [0001] The invention belongs to the technical field of low-voltage control electrical appliances for rail transit locomotives, and in particular relates to a driver controller with redundant functions. Background technique [0002] As the master electrical appliance in the control circuit, the driver controller of rail transit rolling stock is used to control the driving direction, traction and braking of electric locomotives, diesel locomotives, EMUs, urban light rail and subway vehicles. Components, whose reliability and emergency response capability directly affect the safety of operation, therefore, it is particularly important to carry out redundant design for the important and frequently used function in the driver controller, that is, the traction brake function. [0003] At present, the driver controllers used in rail transit rolling stock, the current status of the redundant design of the traction braking function is as follows: 1. Some driver contro...
