Embodiment Construction

[0015] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0016] The most critical idea of ​​the present invention is: through the distributed architecture, that is, the paired arrangement of the same functional service boards, the rail train controller has hot backup redundancy technology, is easy to maintain, and is safe and reliable.

[0017] see figure 1 , a rail train controller, including a backplane 10, a business board 20 and a power board 30.

[0018] The backplane 10 is provided with a circuit 11 designed by PCB (Printed Circuit Board, printed circuit board, made by electronic printing, which is a support for electronic components and a carrier for electrical connection) and connected through the circuit 11. slot 12. The service boards 20 are arranged in pairs, and the same pair of se...

Abstract

The invention discloses a rail train controller which comprises a rear panel, business boards and a power panel, wherein a circuit designed through PCB wiring and slots connected through the circuit are formed in the rear panel; the business boards are arranged in pairs, and the same pair of business boards has the same function so as to be used for hot standby redundancy; the power panel is provided with two paths of identical independent power circuits to be used for switching any one power supply with failure to another one during failure; the business boards and the power panel are inserted into the slots; and the two independent power circuits on the power panel are respectively used for supplying power to two business boards in the same pair of business boards. The rail train controller disclosed by the invention has the beneficial effects that the business boards with identical functions can be arranged in pairs in the rail train controller and are used for cooperative operations, and when any one of the pair of business boards fails, the control power can be timely switched to the other business board, so that operation of the whole system is not influenced, and a phenomenon that unpredictable results are caused by single-point failure is avoided.

Description

technical field [0001] The invention relates to the field of train control systems, in particular to rail train controllers. Background technique [0002] The train control system has gone through the development process from ground artificial signal to ATC (Automatic Train Control, automatic train control system, including automatic train protection ATP, automatic train operation ATO, automatic train monitoring ATS). To build a Chinese brand, digital ATC that integrates 3C technology (3C is Communication, Computer and Control, 3C technology is communication technology, computer technology and control technology) will be the mainstream of development. At present, the control components of locomotives, especially rail trains, are mainly composed of mechanical contact relays. After the ATC sends a control command, the control function of the controlled object is realized through a logic circuit composed of several relays. There are many problems such as bad, expensive and dif...
