Embodiment
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
In order to overcome the problem that in prior art, VCU reliability is low, the utility model embodiment provides a kind of redundancy control system.The schematic diagram of the redundancy control system that Fig. 2 provides for the utility model one embodiment, this redundancy control system can be VCU, and as shown in Figure 2, this redundancy control system comprises: primary processor 201, standby processor 202 and redundant manipulator 203; Wherein, this redundant manipulator 203 is electrically connected with primary processor 201 and standby processor 202 respectively; This redundant manipulator 203, for the running status according to primary processor 201 and standby processor 202, controls the switching between primary processor 201 and standby processor 202.
Particularly, the principle of work of the switching that redundant manipulator 203 controls between primary processor 201 and standby processor 202 is: redundant manipulator 203 is connected by parallel bus with primary processor 201 and standby processor 202 respectively, be responsible for redundant manipulator 203 and monitor primary processor 201 and standby processor 202, and control the operational mode of primary processor 201 and standby processor 202: after redundancy control system powers on, primary processor 201 and standby processor 202 start rear random delay a period of time (2 to 5 seconds) and export useful signal afterwards, this useful signal is effective for representing signal high level, this useful signal is: CPUOK, the processor exporting CPUOK signal is at first primary processor 201, after redundant manipulator 203 receives this signal, redundant manipulator 203 exports run signal to primary processor 201, start to perform Train Control function after primary processor 201 receives run signal, certainly, the standby processor 202 not receiving run signal is in hot standby state.When primary processor 201 breaks down, or when primary processor 201 fail self-test causes initiatively abandoning state of activation, its useful signal step-down, so redundant manipulator 203 exports run signal to the standby processor 202 of hot standby state, makes it become state of activation.Finally, redundant manipulator 203 makes to only have a processor to be in state of activation, and then improves the reliability of redundancy control system.
Further, in prior art, primary processor is connected by MVB with standby processor, and because MVB communication cycle is set to 32ms usually, add that bus is shaken, its determination time is set to level second usually, cannot meet higher control overflow.And the utility model embodiment can realize primary processor by increasing redundant manipulator and switch fast for the Millisecond between processor, improve the switching efficiency of redundancy control system.Meanwhile, when primary processor breaks down, because house dog exists, may constantly restart and initialization, the communication of interference MVB.And standby processor also cannot forbid the work of primary processor.Redundant manipulator in the utility model embodiment then can control constantly restarting and initialization of primary processor, and can control primary processor and quit work.Ensure the reliability of redundancy control system.
A kind of optional manner, above-mentioned redundancy control system also comprises storer; The schematic diagram of the redundancy control system that Fig. 3 provides for another embodiment of the utility model, as shown in Figure 3, this redundancy control system comprises: primary processor 301, standby processor 302, redundant manipulator 303 and storer 304, wherein primary processor 301, standby processor 302, redundant manipulator 303 and above-mentioned primary processor 201, consistent for processor 202, redundant manipulator 203 function, does not repeat them here.This storer 304 is electrically connected with redundant manipulator 303; Storer 304 is for storing the data of primary processor 301 and standby processor 302.
Another kind of optional manner, Fig. 4 is the utility model schematic diagram of redundancy control system of providing of an embodiment again, as shown in Figure 4, this redundancy control system comprises: primary processor 401, standby processor 402, redundant manipulator 403 and storer 404, wherein primary processor 401, standby processor 402, redundant manipulator 403 and above-mentioned primary processor 201, consistent for processor 202, redundant manipulator 203 function, does not repeat them here.This storer 404 is electrically connected with primary processor 401 and standby processor 402 respectively; Storer 404 is for storing the data of primary processor 401 and standby processor 402.
Above-mentioned storer can as the sharing data area of primary processor and standby processor, synchronous for control signal, ensures the continuity that controls after redundancy switches to export and consistance.Primary processor and standby processor access storer by parallel bus, and the synchronous control data of needs is write this storer, and when there is redundancy switching, the standby processor after switching reads synchrodata from storer, can realize control synchronization.
It should be noted that, above-mentioned parallel bus can be (VersaModuleEurocard is called for short VME) bus, and usual primary processor and standby processor are arranged in same cabinet, adopt same backboard and power supply.Described redundant manipulator is the controller based on field programmable gate array (Field-ProgrammableGateArray is called for short FPGA); Described storer is static RAM (StaticRandomAccessMemory, SRAM).
Further, above-mentioned redundant manipulator comprises alarm module; Described alarm module be used for when described primary processor and described standby processor running status all exception time send alarm signal.Thus improve the reliability of redundancy control system.
