Summary of the invention
The object of the invention exactly in order to overcome the defective that above-mentioned prior art exists, provides a kind of reliable rail traffic platform shield door central redundancy control system.
To achieve these goals; The present invention has adopted following technical scheme: the central redundancy control system of a kind of rail traffic platform shield door; Be connected by communication with field apparatus, comprise main central controller, subsequent use central controller, primary input output device, subsequent use input-output device, master network module and backup network module; Main central controller links to each other with the backup network module communication with the master network module respectively with subsequent use central controller, and is connected by communication with primary input output device and subsequent use input-output device respectively through master network module and backup network module; The primary input output device links to each other with field apparatus respectively with subsequent use input-output device, links to each other through the synchronizing cable both-way communication between main central controller and the subsequent use central controller.
The Hardware configuration of described primary input output device and subsequent use input-output device is identical and network is identical, with redundancy right form configuration and operation.
The Hardware configuration of described subsequent use central controller and main central controller is identical and transmit input/output signal in the same manner.
Described main central controller and subsequent use central controller are worked simultaneously, and in normal operation, main central controller works in the foreground, the operation of output main control signal control system, and subsequent use central controller works in the backstage.
Described main central controller and subsequent use central controller can be reset through the hardware toggle switch.
Described master network module and backup network module real-time online, subsequent use each other.
The central redundancy control system of rail traffic platform shield door of the present invention is formed central controller AM/BAMs active redundancies technology simultaneously with two central controllers; Form activation or non-activation active redundancy technology with two input-output device.Two mixed-media network modules mixed-media redundancies, two power module redundancies are uploaded the interface module redundancy for two.Can be at central controller, input-output device, power module, mixed-media network modules mixed-media uploads that interface module is single to go wrong or during fault, and the system that can guarantee can normal and stable operation, has improved the reliability of system.
Description of drawings
Fig. 1 is the structured flowchart of the central redundancy control system of rail traffic platform shield door of the present invention.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
Referring to Fig. 1; The central redundancy control system of rail traffic platform shield door of the present invention; Be connected by communication with field apparatus 1, comprise main central controller 2, subsequent use central controller 3, primary input output device 4, subsequent use input-output device 5, master network module 6 and backup network module 7.Main central controller 2 is connected by communication with master network module 6 and backup network module 7 respectively with subsequent use central controller 3, and is connected by communication with primary input output device 4 and subsequent use input-output device 5 respectively through master network module 6 and backup network module 7; Primary input output device 4 links to each other with field apparatus 1 respectively with subsequent use input-output device 5, links to each other through synchronizing cable 8 both-way communications between main central controller 2 and the subsequent use central controller 3.Main central controller 2 and subsequent use central controller 3 also are connected with mixed-media network modules mixed- media 9,10 respectively, and link to each other with comprehensively monitoring interface 13,14 through network 11,12 respectively.Shown in the figure the 15, the 16th, be the power module that main central controller 2 and subsequent use central controller 3 provide power supply, subsequent use each other.
System constitutes from the Hardware configuration to the network and " redundancy " control theory is deferred in software control etc. all the time, and the fault of any one parts or network all can not influence the normal ON/OFF of on-the-spot shield door.The redundant principle of concrete each several part is following:
Main central controller receives data through network communication from the primary input output device; These data are carried out the logical process union; Produce main central controller controls signal according to result, transfer data to output of primary input output device and comprehensively monitoring interface through network communication.
Subsequent use central controller and main central controller Hardware configuration are identical and transmit input/output signal in the same manner.These two central controllers are through redundant clock, data, the user program of the synchronous central controller of optical fiber synchronously simultaneously; And the self-check program through central controller detects main central controller fault, mistake, unusual in each scanning process; If being checked through main central controller goes wrong, redundant system just can automatically switch to subsequent use central controller work.
In order to ensure not having the switching of impact, the exchange of rapid and reliable data; The same user program of two central controller automatic receptions, data block, procedural image content, inside information (like timer, counter, bit memory) or the like guarantee that two sub-cells all are latest update all the time.
Two cover central controller AM/BAMs are worked simultaneously; Under the state of operate as normal; Main central controller works in the foreground; The operation of output main control signal control system, subsequent use central controller works in the backstage, and main central controller, subsequent use central controller can be reset through the hardware toggle switch.
The primary input output device is identical with subsequent use input-output device Hardware configuration and network is identical, and it is redundant right to form through hardware configuration.In normal operation; Activate the work of primary input output device by central controller; There are bad passage or entire equipment passage to damage or make mistakes when central controller detects this input-output device, just stop this equipment work and activate subsequent use input-output device simultaneously and work on by central controller.
Field apparatus links to each other with primary input output device network through redundant communication interface, carries out swap data.Port of field apparatus communication in normal operation and primary input output device swap data; Another port is in running background.When a port broke down, put into operation automatically in the another port and 2 swap datas are exported in primary input.
Two ports of field apparatus can be reset the master-slave redundancy mode through the hardware toggle switch.
Central control system is carried out communication through the network interface and the comprehensively monitoring of redundancy.Main interface carries out swap data under the normal condition, and spare interface is in running background.When main interface breaks down, the automatic and comprehensively monitoring generation real time data exchange of spare interface.Active and standby interface can carry out redundancy setting through software.
Central controller power supply power module redundant configuration, when the main power source module fault, standby power supply is still worked, and the mains power failure signal is in time diagnosed and sent to subsequent use central control system, with the safeguards system reliability service.
Central controller, power module and mixed-media network modules mixed-media are all supported online insertion and removal, realize not shutting down online the maintenance.Safeguards system is reliable, safe operation.
The switch door and the safety interlocking system of redundant closed-loop type are set, guarantee the screen door reliability service.
