Embodiment Construction
[0021] Hengjun Railway Signal Star full-electronic computer interlocking system (HJ-RSSE) main-standby switching module is an auxiliary module of the control system, which is used to complete the status display of the two interlocking systems and the manual control of the two-system switching functions.
[0022] figure 1 It is a structural diagram of a dual-system switching system for an interlocking machine. The module includes a master and a slave, that is, two ARMs. ARM1 and ARM2 receive data from four serial ports at the same time, and send data from the serial ports COM1, COM2, COM3, and COM4. The data is analyzed, and the output signal lights up the corresponding indicator light. At the same time, the two ARMs collect the state of the switching button. If the switching command is collected, the host will send the switching command to the two interlocking systems after the two ARMs are consistent.

The invention relates to an interlocking machine double-system switching system and a control method thereof. The interlocking machine double-system switching system comprises a power supply module, adouble-system switching board, a main / standby switching module, a communication module, a switching module, a lighting module and a watchdog module, the switching module comprises a switching buttonand an optocoupler, and a host sends a switching command to an interlocking machine double-system to realize manual switching of the interlocking machine double-system; the lighting module comprises an indicating lamp, an optical coupler and a relay. The indicating lamp receives the state data of the interlocking machine double-system through the host and a slave so as to light the indicating lampin the corresponding state. The control method adopts a combined fault safety principle and a redundancy principle. The state of the switching button is collected through the host and the slave, theswitching command is sent, the function of manually switching the interlocking machine double-system is achieved, the real-time monitoring of the state of the interlocking machine double-system is achieved, and the current states of the two systems are displayed in the panel indicating lamp.
Description
technical field [0001] The invention relates to a switching device, in particular to a dual-system switching system and control method of an interlocking machine. Background technique [0002] In recent years, the automatic control technology of railway stations has developed rapidly, and the core components such as interlocking computing computer, interlocking software logic and driving execution circuit that constitute the control system have been greatly developed and improved. On the basis of actively introducing foreign advanced technology, the domestic railway industry is gradually moving towards the direction of localization. At the same time, the Ministry of Railways has gradually increased the requirements on the safety, reliability, availability and maintainability of the computer interlocking system, and clearly put forward the requirement that the safety integrity level of the computer interlocking system should reach SIL4. SIL (Safety Integrity Level) safety in...
