Embodiment
Below in conjunction with accompanying drawing the present invention is done further explain.
Apparatus of the present invention structured flowchart such as Fig. 1～shown in Figure 5; Fig. 1 is apparatus of the present invention general structure block diagram, comprises land Master Control Center host computer 1, GPRS module 2, antenna 3, GPRS communication network 4, safety valve monolithic processor control device 5, electromagnetic relay 6, subsurface safety valve on-site control device 7, well mouth release valve on-site control device 8 and well cover safety valve on-site control device 9.
Wherein, Land Master Control Center host computer 1 is connected with a GPRS module; As shown in Figure 2; Land Master Control Center host computer 1 is common PC computing machine, is connected with the GPRS module through serial ports, and the TX end of computing machine, RX end and earth terminal GND are connected TX end, RX end and the earth terminal GND of a GPRS module respectively.
The safety valve monolithic processor control device is developed according to the oil field industrial production environment voluntarily, and port organization figure is as shown in Figure 3, comprises various communication interfaces; Wherein, 24+, 24-, 5V+, 5V-are power supply terminal, and PT, PR are RS-232 agreement terminal; RS-485+, RS-485-are RS-485 agreement terminal; CAN1, CAN2 are the CAN bus terminal, and G, G1 are ground terminal, and D01～D04, D11～D14 are the I/O port.
The safety valve monolithic processor control device is connected with the 2nd GPRS module through RS-232, and the PT port of safety valve monolithic processor control device, PR port, G1 port connect TX port, RX port and the earth terminal GND of the 2nd GPRS module respectively, and be as shown in Figure 4.
The safety valve monolithic processor control device is connected as shown in Figure 5 with electromagnetic relay; Output terminal D01～the D03 of safety valve monolithic processor control device connects the input end of first electromagnetic relay, second electromagnetic relay and the 3rd relay successively; The 24V+ power end of safety valve monolithic processor control device connects another input end of first electromagnetic relay, second electromagnetic relay and the 3rd relay respectively, and the output terminal of three electromagnetic relays connects subsurface safety valve CS 7, well mouth release valve CS 8, well cover safety valve CS 9 respectively.
Receive the control command of closed safe valve when the safety valve monolithic processor control device after, executive routine is given low level of each port of D01～D03; Just having electric current like this in the coil of electromagnetic relay passes through; Produce downward the suction-combining force, drive armature and move downward, so the upper and lower contact adhesive in the electromagnetic relay; Circuit is connected, and carries out shutoff operation; In the Next Command cycle, D01～D03 recovers high level, current vanishes in the coil; Armature is got back to original position under the effect of spring; Contact separation because electromagnetic relay and site safety valve CS are connected in parallel, therefore substitute site safety valve CS and carries out closing motion.
Fig. 6 is safety valve monolithic processor control device control safety valve closing flow path figure, owing to the ordinary production that is related to the oil gas well of closing of safety valve, is can not carry out control operation generally speaking therefore, has only and in case of emergency just opens this function.So we have taked the necessary precautionary measures for fear of maloperation, have only host computer continuous order safety valve monolithic processor control device that sends the closed safe valve for 3 times in 1 second just to think efficient in operation.
After the safety valve monolithic processor control device receives the control command that requires the closed safe valve that host computer sends; At first carry out the verification of data; According to safety valve shutdown command data protocol require each of check data, if mistake is then returned reading of data again, if do not have wrong then carry out the decoding of data; Described safety valve closing control order data agreement is as shown in Figure 7; This agreement comprises 7 fields in the present embodiment, be respectively prefix, safety valve monolithic processor control device address, command word 1, command word 2, state 1, state 2, verification and, the definition of each field is following:
Prefix: start field is 0x55;
Safety valve monolithic processor control device address: can independently be provided with, for example: 0x81;
Command word 1, command word 2: the order of closed safe valve, 0x01,0x01 close subsurface safety valve, and 0x04,0x04 are shut-in well cover safety valve, and 0x02,0x02 are safety valve on the shut-in well;
State 1, state 2: representative be the output state that the safety valve monolithic processor control device is inquired about corresponding relay;
Verification and: XOR from safety valve monolithic processor control device address to last byte of state 2 with.
Decoded data are judged; Closing well control command if not needs is then returned reading of data again, if the closing well control command that needs then makes the closing well data counter add 1; Reach 3 execution next-step operations in 1 second up to satisfying, otherwise return reading of data once more.If counter did not reach in 1 second 3 times then counter O reset.
When satisfying the closing well data counter in 1 second during to 3 condition, it is effective to the control command of safety valve that the safety valve monolithic processor control device is thought, just gives 0 mouthful of low level of corresponding D, carries out the operation of closed safe valve.
Timer is set makes the safety valve monolithic processor control device keep for the low level of D0 mouth 3 seconds; Level at this 3 seconds internal safety valve monolithic processor control device detection D0 mouths; If for low level then send acknowledge message prompting safety valve to host computer and successfully closed, otherwise detect again.
