In preferred embodiment of the present utility model, provide a kind of coking automatic control system emulating instrument dial plate, comprise insulation card,Valve module, coke drum module, pipeline module, valve module, coke drum module are communicated with control system respectively, valve mouldThe instruction of piece, coke drum module receiving control system, and by state Hui Xun to control system, insulation card on install simulationPipeline and valve, the simulation pipe-line system of composition coking production flow process; Valve module comprises that valve, valve circuit module showShow control panel and valve circuit, actuation time and the characteristic of valve circuit to valve simulated control, and valve circuit module is aobviousShow that control panel is for showing the state of valve and valve manually being controlled, valve circuit module shows that control panel comprises valveStatus bar, button, the aperture state of valve is indicated by valve state bar, by the switch of the manual control simulation valve of buttonOperation; Coke drum module comprises coke drum circuit module display panel and coke drum circuit, and coke drum circuit is used for simulating coke drumProduction status, coke drum circuit module display panel for show the coke drum that coke drum circuit simulates pressure, temperature,Material state. Pipeline module comprises upstream line, the downstream line of valve, the pipeline light-emitting diode display part of valve, pipeline LEDDisplay device is used to indicate in the downstream line of upstream line, valve of valve and has or not media flow. The upstream line of valve,Between the downstream line of valve and valve, be communicated with by gate circuit respectively. Valve circuit, coke drum circuit pass through respectively ModbusBus is connected with control system. Wherein, valve state bar is valve light-emitting diode display part. As shown in Figure 1, (1) forControlled valve, the red LED indicator lamp that valve state bar only uses the left side 2. with the green LED indicator lamp on the right 3.. RedUnder the condition that 2. LED light allows to close in control system, will not stop flicker, alert can be carried out " pass " behaviourDo, " pass " key on now can pushing button closes operation, and valve will be carried out and close action. When valve is in complete shut-down shapeWhen state, red LED indicator lamp, 2. by Chang Liang, represents valve contract fully. If 3. green LED indicator lamp is permitted in control systemUnder the condition of being permitted out, will not stop flicker, alert can be carried out " opening " operation, now can push button and 5. go up" opening " key open operation, work is started in execution by valve. When valve is during in full-gear, green LED indicator lamp 3.By Chang Liang, represent valve contract fully. Can set the switch time of valve according to actual valve door switch ratio. (2) for toolHave the valve of regulation, 4. valve light-emitting diode display part is made up of 10 LED lamps, is used for showing valve opening, many oneLED lamp is lighted and is represented that the aperture of valve increases by 10%, red LED indicator lamp 2. with green LED indicator lamp 3. with 1) in switchValve is the same, is used for prompt switch operation. Its operation logic is with 1) described in, difference is to be come by 10 LED lampsDynamically show its aperture. It in Fig. 1, is 6. pipeline circuit interface.
Wherein, in the time having media flow in the downstream line of the upstream line of valve, valve, light pipeline corresponding on its pipelineLight-emitting diode display part. This function is to connect power supply by gate control circuit to realize, its principle as shown in Figure 5: onPlay pipe road and downstream line are connected on a valve by electric interfaces, if upstream line inside has been full of medium,This segment pipe module will obtain power supply, thereby light the pipeline light-emitting diode display part that pipeline section is corresponding. If valve is in closing shapeState, the gate circuit that connects upstream line, downstream line power supply will cut off, thereby make the downstream line must not electricity, thus point notThe pipeline light-emitting diode display part that bright pipeline section is corresponding, be used for simulation do not have medium to be left to this pipeline. In the time of valve open, valve electricityRoad control gate circuit is opened, the power supply of downstream line and the power connection of upstream line, obtain electric after, downstream line is lighted, mouldAfter plan valve open, the MEDIA FLOW of upstream is led to this technical process of downstream line. When selecting according to the type of valve and quantityAfter corresponding valve circuit, just can arrange coking automatic control system emulation instrument according to the PID figure of delayed coking systemThe layout of dish. Each valve and coke drum module are fixed on the basal plane of insulation card, by pipeline module by each valve and pipeRoad annex couples together according to the layout of PID figure, just can realize the hardware components of emulating instrument dial plate.
According to " a kind of automatic operation system for delayed coking coke chamber " (patent No.: ZL200720085318.X) propose fromThe safety control function of moving operation, realizes the simulation to valve control by software. The implementation process of this software is as follows: instituteSome intelligent nodes, comprise that each valve, coke drum and intelligent valve annex (as temperature, pressure display instrument table) pass throughModBus bus is connected, and complement is opened up in its connection can be as shown in Figure 7. Whole system forms the ModBus of an one master and multiple slavesNetwork. Master controller (hereinafter to be referred as host node) completes the chain control function of whole control system as the host node of system,This master controller can be mixed corresponding control software with a PC and be realized in emulation instrument panel system, also can lead toCrossing a PLC programmes to realize. Each valve and intelligent pipeline annex are as from node, and each intelligence distributes one from nodeIndividual from plane No., so that communicate with host node. Respectively want to respond control instruction and the inquiry that host node sends from nodeInstruction. Control instruction comprises: allow from node open operation, allow from node close operation, permission from node action (can open,Also can close); Query statement is for inquiring about the state from node. From node response control instruction, on panel, point out: asAllow out operation, open the flicker of prompting LED lamp, now operator can press " opening " key, to simulate out valve operation, due toMain controller is only given to permit and is opened authority, do not give to permit to close authority, thus now if operator presses " pass " key, valve would not also be carried outClose operation. Same if permit pass control instruction, only relevant valve operation effectively, is driven valve and is operated by invalid, to ensure safety.The circuit module of simulation valve, coke drum, pipeline meter uses Modbus bus to be connected in circuit logic, by embeddedRealize the communication between each module in the Modbus of circuit module inside agreement, RS485 circuit is as the thing of ModBus agreementReason layer.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, andAll these improvement and conversion all should belong to the protection domain of the utility model claims.
