Tramcar positive line signal control system and control method thereof

Abstract

The invention provides a tramcar positive line signal control system and a control method thereof. The tramcar positive line signal control system comprises a control module with an interlocking logical judgment function and a controlled equipment unit connected with the control module by virtue of a communication interface, wherein the control module is respectively in communication connection with a dispatching control center and vehicle-mounted wireless equipment by virtue of communication interfaces. According to the control method, interlocking logical judgment is adopted for performing automatic control and manual control on a tramcar; the positive line signal control system is mainly used for finishing logical operation and logic control of a positive line interlocking system; furthermore, by virtue of cooperation of the dispatching control center and all the modules, the tramcar positive line signal control system has relatively perfect self-diagnostic capability, and has functions of detecting and alarming working conditions of equipment such as a route indicator and lever stand; display and alarm are performed on the control center by virtue of a wireless transmission system or an optical cable and remote fault diagnosis is implemented. The tramcar positive line signal control system can be used for improving the efficiency and safety of the tramcar in passing tracks and improving the operation automation level and the operation intellectualization level.

Description

technical field [0001] The invention relates to a tram main line signal control system and a control method thereof. Background technique [0002] With the continuous improvement of my country's urbanization level, the pressure on urban traffic is increasing, and rail transit plays an important role in the urban traffic system. However, the huge cost and long construction period of the light rail subway limit its development in small and medium-sized cities. Facing the current urgent transportation needs, modern trams with low cost and short construction period have been recognized by the city as a transportation mode with less energy consumption per unit, no pollution, and large transportation capacity. The revival of modern trams in Europe also reflects the excellent ability of trams to relieve urban traffic pressure. In my country, cities such as Tianjin, Dalian, and Shanghai already have tram lines in operation, and many small and medium-sized cities have actively inco...

AI Technical Summary

Problems solved by technology

[0004] Through comprehensive analysis, it can be seen that the key point of the above technology is to integrate the various control parts of the existing trams, to collect the data to the control center through the network connection control, and to complete the unified dispatching control through the control center; however, the reality of the tram The operation is very complicated, and the operating environment is also sudden. Simple data integration control cannot guarantee the safety and reliability of the tram

The defects of the above-mentioned technology are as follows: 1, the logic operation and logic control of the automatic interlocking system cannot be carried out to the tram, lack of relatively perfect self-diagnosis function, and no alarm function to sudden failure; 2, the control and logic control of the tram Scheduling lacks a complete and reasonable control scheme, especially when the tram runs to the turnout, simply relying on the remote control of the control center cannot guarantee the accurate and safe passage of the tram, which involves precise control of the turnout track, multiple trams Through the coordination of priority rights and the early warning and processing of failures, etc.; the above-mentioned patented technology obviously does not give a specific technical solution; 3. The above-mentioned monitoring information collection is not comprehensive, and the tram is different from the subway. Temperature and humidity, smog, access control and other environmental factors that can affect the normal operation of trams are obviously not involved in the above technologies; 4. The remote control and scheduling methods of the control center in the above technologies cannot be quickly and randomly switched from the manual driving mode of trams , which is very detrimental to the control and safety of the vehicle in emergencies
