Switchyard discrete control system

Abstract

The invention relates to switchyard control, in particular to a switchyard discrete control system. The switchyard discrete control system comprises turnout modules, speed reducer modules and a peak point module. Each turnout module corresponds to a set of turnouts, drives a turnout point switch, collects switch indications, further collects track circuits of a turnout section and front and rear turnout adjacent sections and collects / drives front and rear turnout adjacent shunting signal machines. Each speed reducer module is composed of an outdoor processor and a corresponding interface sub-module; an outdoor control module comprises the turnout modules, the speed reducer modules and the peak point module. According to the control system, the engineering building cost and maintenance cost of the switchyard discrete control system are reduced, the technical threshold and mounting, use and maintenance technical thresholds of switchyard control are reduced, more switchyards are benefited, the standard outdoor control module can serve as an independent product matched with execution equipment to be independently manufactured and sold, and the system integrated environment is optimized.

Description

technical field [0001] The invention relates to a shunting yard control, in particular to a shunting yard discrete control system. Background technique [0002] Yard specifically refers to the railway yard / station where shunting operations are the main body. Shunting refers to the driving operations caused by the inversion, transfer, disintegration, marshalling, loading and unloading of trucks or (and) passenger cars between different lines within a depot / station. The characteristic of shunting operation is that it is commanded by shunting signals or hand signals, and the running speed is relatively low. Special shunting locomotives are often used as traction power. The shunting route needs to support efficient and flexible forward and backward return operations due to the frequent shuttles between different routes to pick up and deliver vehicles. Shunting yards include flat shunting yards and hump shunting yards, which are commonly found in marshalling yards, station frei...

AI Technical Summary

Problems solved by technology

[0006] 1. The number of cables used is large, and the construction and installation costs of laying cables are high

[0007] 2. The signals of devices such as axle counting, radar, length measurement, and weight measurement are weak, and they are susceptible to electromagnetic interference during long-distance transmission, which affects the accuracy of signal acquisition, which in turn affects control accuracy and performance

[0008] 3. A large number of connecting cables with radioactive layout is the weakest link of lightning intrusion, and it is easy to be damaged by lightning induction and damage indoor and outdoor electronic and electrical devices

[0013] 3. Without exception, all control hosts and control units of various station interlocks are concentrated indoors, and are connected to various switch machines, track circuits, signal machines, etc. that are several kilometers away from the site through cable solid circuit lines. The quantity of use is large, and the construction and installation costs of laying cables are high

[0014] 4. The concentration of control units and interlocking equipment forms a large number of remote and radial connection cables, which are the weakest link of lightning intrusion, and are easily damaged by lightning induction and indoor and outdoor electrical equipment

[0015] 5. Some turnouts of special lines connecting yards / stations are far away from the signal building beyond the limit range of centralized control equipment and cannot be included in centralized control

[0017] Since a large number of on-site control and acquisition devices are transported hundreds of meters away from the indoor centralized control equipment and connected by long cables, there are some shortcomings and deficiencies

[0018] 1. The system is limited to the railway car depots used in the marshalling yard

[0019] 2. The number of cables used is large, and the construction and installation costs of laying cables are high

[0020] 3. A large number of radioactive connecting cables are the weak link of lightning intrusion, which is easy to be damaged by lightning induction and damage indoor and outdoor electronic / electrical devices
