Problems solved by technology

The common point of these three control methods is that the drive circuit performs the braking or release operation of the parking device through the relay in the tail signal building, and the control drive line is too long; the detection signals are also sent to the tail signal building through cables for collection. Requires a large number of cables, while increasing construction difficulty and workload

Embodiment Construction

[0020] The present invention will be further described below in conjunction with drawings and embodiments.

[0021] Such as figure 1 , The new hydraulic controllable parking device control system consists of 3 parts: the relay room of the tail signal building, the duty room of the tail signal building and the field control equipment. They all work in a dual-machine redundant mode and carry out long-distance communication through CAN bus.

[0022] The relay room of the tail signal building includes a monitoring machine and a 48-way switching value acquisition board. The monitoring machine is only used to monitor relevant information such as the status of the on-site parking device, the position of the tail switch, the status of the signal machine, and the idle track; the 48-way switching value acquisition board (ie The lower computer in the relay room) determines the status of the original equipment on the site by collecting the status of the relay-related nodes in the relay ro...

Abstract

A novel parker control system based on a CAN bus consists of three parts: a tail signal building relay room, a tail signal building duty room and field control equipment which all operate in a dual-machine redundancy mode and which carries out long distance communication through the CAN bus. The control system overcomes the shortcoming that an existing control system has a long control driving line, saves a lot of cables, reduces the construction difficulty and the workload, has good real-time performance, fast speed, and high reliability, fully satisfies the communication requirement of a marshalling yard tail parker online monitoring system, and is worth promoting and using.

Description

[0001] Technical field [0002] The invention relates to a novel parking device control system based on CAN bus, which is suitable for the mechanical field. Background technique [0003] For a long time, the anti-slip tools at the tail of the hump have mainly used iron shoes as the main shunting equipment. Iron shoes, as a simple speed regulation and anti-slip equipment, were indeed suitable for my country's national conditions and road conditions at the time of the development of the hump. During the anti-skidding operation using iron shoes at the tail of the hump, the operation status of the shunting locomotive was observed through manual contact, and the manual guarantee of "putting shoes" and "removing shoes" was not only labor-intensive and the working environment was harsh, but also The low labor efficiency directly affects the further improvement of the hump tail marshalling ability. What's more serious is that shunting accidents caused by "missing release" and "missin...
