Abstract

The invention provides a rail transit signal acquisition system, which relates to the technical field of rail transit signal control. The system includes controllers, power modules, a level signal acquisition module, output detection modules, a power controller, and a dynamic driver. The system specifically includes a first controller, a second controller, a first power module, a second power module, a first output detection module and a second output detection module. The level signal acquisition module includes a level input acquisition circuit, a level pulse acquisition circuit and a differential pulse acquisition circuit. The power modules are respectively connected with the controllers and the output detection modules. The controllers are respectively connected with the output detection modules, and are connected with the power controller. The two controllers are connected by a double-interface RAM. The power controller is connected with the dynamic driver. By using the technicalscheme, the technical problems of poor applicability and low reliability in the prior art are alleviated, the applicability of a rail transit output signal control system is enhanced, and the reliability is improved.

Description

technical field [0001] The invention relates to the technical field of rail traffic signal control, in particular to a rail traffic signal acquisition system. Background technique [0002] At present, my country's rail transit industry is developing rapidly. According to the latest statistics, 22 cities across the country have opened subways, with a total operating mileage of 2,764 kilometers. At present, 39 cities have been approved for subway construction, with a total planned mileage of more than 7,300 kilometers. In 2020, it is expected that more than 50 cities will be approved to build subways, the operating mileage of urban rail transit will reach about 6,000 kilometers, and the new investment is expected to exceed 2.4 trillion yuan. [0003] At present, the signaling system in rail transit is the "brain" of rail transit operation, responsible for organizing the normal operation of the entire rail transit and ensuring the safety of operation. At the same time, the sig...
