Further, in step 1), when the centralized control system and the intelligent anti-misoperation host of the master station perform simulated and previewed anti-misoperation verification on all operation items in the one-key sequential control operation command, and the autonomous verification result obtained by the centralized control system and the verification result of the intelligent anti-misoperation host are correct, the master station issues the one-key sequential control operation command to the one-key sequential control operation host of the transformer substation.
The information interaction under the master station mode further comprises information interaction between the centralized control system and the intelligent error-preventing host before the master station issues the one-key sequential control operation instruction, and the centralized control system can obtain a final verification result through the double-set verification process of the centralized control system and the intelligent error-preventing host and the information interaction process between the intelligent error-preventing host and the centralized control system, so that the verification result is more reliable.

After the one-key sequential control operation instruction is finished (wherein a mark for finishing the operation instruction can be that the intelligent anti-misoperation host confirms that the equipment is successfully shifted), the station anti-misoperation host is locked to release the unique operation right of the equipment, so that the equipment can be controlled by other equipment which needs to be controlled after the one-key sequential control operation.
Further, in step 3), when the method for obtaining the single step operation instruction is the single step operation instruction execution command directly issued by the centralized control system of the master station, the single step operation instruction execution command is issued by the shutdown of the data communication network.
The method also comprises the information interaction process between the centralized control system and the data communication network shutdown in the master station mode, namely, a sequence control module of the centralized control system of the master station transmits an objectified operation instruction in the original remote control channel and compares the objectified operation instruction with the remote control instruction of the data communication network shutdown to realize the remote control instruction intercommunication between the centralized control system and the data communication network shutdown; the centralized control system sequence module acquires the objectified query instruction through the original data transmission channel so as to realize real-time data intercommunication between the centralized control system and the data network shutdown, and further realize information interaction between the centralized control system and the data communication network shutdown.

Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent.
The embodiment of the method for key sequential control information interaction of the centralized control station monitoring system comprises the following steps:
in order to meet the technical requirements of one-key sequential control, the method for one-key sequential control information interaction in the embodiment not only has information interaction of a centralized control station end, operation and maintenance Ban Duan and a transformer substation end, but also comprises information interaction of the transformer substation end and information interaction in a master station mode, wherein the information interaction of the transformer substation end is divided into information interaction between a one-key sequential control host of the transformer substation and an intelligent error prevention host, information interaction between the one-key sequential control host of the transformer substation and spacer layer equipment, information interaction between the one-key sequential control host of the transformer substation and auxiliary equipment monitoring system and information interaction between a centralized control station (operation and maintenance) and a transformer substation; the information interaction flow in the master station mode is divided into information interaction of the centralized control system and the intelligent anti-misoperation host, information interaction of the intelligent anti-misoperation host and the station end anti-misoperation host, information interaction of the centralized control system and the intelligent gateway machine and information interaction of the centralized control system and the video master station, so that the information interaction flow is more complete by the method of one-key sequential control information interaction.
The one-key sequential control process mainly comprises the steps that a master station sends a one-key sequential control instruction to a substation end, and a one-key sequential control host at the substation end receives the one-key sequential control instruction and then performs corresponding control operation according to one-key sequential control logic, and the one-key sequential control information interaction method in the embodiment comprises the following steps:
1) In the master station mode, when one-key sequential control is needed, information interaction is firstly carried out between a centralized control system of the master station and the intelligent error prevention host computer so as to carry out error prevention verification on all operation items of the one-key sequential control;
as shown in fig. 6, after the centralized control system initiates information interaction, the intelligent anti-misoperation host machine performs simulation previewing according to the previewing instruction sent by the centralized control system, the whole process anti-misoperation checking is performed on the operation ticket during simulation previewing, the checking result is returned to the centralized control system, meanwhile, the centralized control system also performs the whole operation project to obtain an anti-misoperation checking result of the centralized control system through the SCADA anti-misoperation checking process, and the centralized control system phase the anti-misoperation checking result of the centralized control system with the checking result returned by the intelligent anti-misoperation host machine, so that the total previewing anti-misoperation checking result is obtained. The method of the embodiment can enable the centralized control system to obtain a final verification result through the double-set verification process of the centralized control system and the intelligent error-preventing host machine and the information interaction process between the intelligent error-preventing host machine and the centralized control system, and the verification result is more reliable.
2) When the master station performs error-proof verification on all operation items of one-key sequential control and the obtained error-proof verification results are consistent, a one-key sequential control operation instruction is issued to a transformer substation end;
the operation and maintenance work of the centralized control station initiates information interaction with the one-key sequential control host computer at the transformer station end through a dispatching data network and a data network shutdown of a safety I area at the transformer station end, and the information interaction between the master station and the transformer station end is divided into a distributed control mode and a comprehensive control mode according to related network safety requirements, and corresponding interaction modes exist between the centralized control station (operation and maintenance work) and the transformer station in the two modes.
In the distributed control mode, the centralized control station (operation maintenance class) end one-key sequential control workstation performs one-key sequential control in a step-by-step mode, and the operation of the one-key sequential control workstation comprises the steps of operation ticket calling, operation ticket previewing, operation ticket executing and the like, as shown in fig. 4, and is an information interaction process between a specific centralized control system and a one-key sequential control host in the distributed control mode; the integrated control mode performs one-key sequential control operation in a merging mode, and only comprises operation ticket execution, as shown in fig. 5, and is an information interaction process between a specific centralized control system and a one-key sequential control host in the integrated control mode.
3) When the one-key sequential control host receives a one-key sequential control operation instruction issued by the master station, the one-key sequential control host of the transformer substation generates an operation ticket and performs operation ticket previewing;
and in the comprehensive control mode, the substation performs identity authentication and matches with a typical ticket after receiving a command for issuing an operation ticket threshold value so as to generate the operation ticket. Based on different control modes, after the operation ticket is generated by the transformer substation, the transformer substation performs operation ticket previewing, as shown in fig. 1, which is a process of performing operation ticket previewing by the one-key sequential control host and the intelligent anti-misoperation host in the embodiment: when the replay is simulated, the intelligent anti-misoperation host machine performs operation ticket whole process anti-misoperation checking according to the replay instruction, the result is returned to the one-key sequential control host machine, meanwhile, the one-key sequential control host machine performs built-in anti-misoperation checking on all operation items through the sequential control host machine to obtain a built-in anti-misoperation checking result, and the one-key sequential control host machine performs the built-in anti-misoperation checking result and the received anti-misoperation checking result returned by the intelligent anti-misoperation host machine to obtain a final total replay anti-misoperation checking result. The error-proof verification of the simulation replay process in this embodiment is based on the double error-proof verification process of the verification of the error-proof verification host and the autonomous verification of the one-key sequential control host, so that the obtained verification result is more reliable.
4) And after the operation ticket previewing is finished, an instruction execution stage of one-key sequential control operation is carried out.
The command execution stage of the one-key sequential control host machine for one-key sequential control operation is realized through information interaction between the one-key sequential control host machine and the spacer layer equipment, and as shown in fig. 2, the one-key sequential control host machine of the transformer substation initiates information interaction in the command execution stage, the spacer layer equipment issues an operation command, equipment operation is completed, and the state after equipment displacement is returned to complete information interaction.
In the comprehensive control mode, the one-key sequential control host machine performs intelligent error prevention verification before each operation item is executed, as shown in fig. 1, when the operation instruction is executed, the intelligent error prevention host machine performs single-step error prevention verification on the control instruction sent by the one-key sequential control, and returns a verification result to the one-key sequential control host machine, namely, during the execution process of the operation instruction, the one-key sequential control host machine and the intelligent error prevention host machine perform error prevention double verification, the verification can be continuously executed, and otherwise, error information is returned.
In the distributed control mode, because the distributed control instruction is distributed and sent by the centralized control system of the master station, each operation item of the distributed operation is issued by the centralized control system of the master station, so in the distributed control mode, an error proofing process is performed based on the centralized control system, as shown in fig. 6, when the operation instruction is executed, the intelligent error proofing host machine also performs single-step error proofing check according to the control instruction sent by the centralized control system and returns to the centralized control system, namely, in the operation instruction process, the centralized control system and the intelligent error proofing host machine perform error proofing double check, and if the check is inconsistent, the operation is terminated and error information is prompted. And in the error proofing process, the intelligent error proofing system and the station end error proofing system also perform an information interaction process, as shown in fig. 7, after the intelligent error proofing system receives an error proofing request sent by the centralized control system, a remote control unlocking command is sent to the station end error proofing host, if unlocking is successful, a success message is returned to the intelligent error proofing host, failure information is returned if the unlocking is unsuccessful, at the moment, the intelligent error proofing host obtains the unique operation right of the equipment, then the centralized control station executes sequential control operation, after the intelligent error proofing host confirms that equipment displacement is successful, a remote control locking command is sent to the station end error proofing host, after the station end error proofing host is successful in locking, a locking success message is returned to the intelligent error proofing host, and after the intelligent error proofing host receives the locking success message, the unique operation right of the equipment is released. When the centralized control system issues instructions, the centralized control system and the data communication gateway also perform an information interaction process, as shown in fig. 8, a sequence control module of the centralized control system issues an objectified operation instruction on an original remote control channel, and compares the objectified operation instruction with a remote control instruction of the data communication network shutdown, so as to realize the intercommunication with the remote control instruction of the data communication network shutdown; and the centralized control system sequence module acquires the objectified query instruction through the original data transmission channel, so that real-time data intercommunication between the data network and the shutdown is realized. And the information interaction between the centralized control system and the shutdown of the data communication network is realized through the two points.
In addition, in the instruction execution stage of the one-key sequential control operation, the method further obtains the video system discrimination result of the single project process through the information interaction between the one-key sequential control host computer of the transformer substation and the auxiliary equipment monitoring system, as shown in fig. 3, the information interaction between the one-key sequential control initiation and the auxiliary equipment of the transformer substation is carried out, when the one-key sequential control is carried out, each operation project needs to send a linkage signal to the auxiliary monitoring system before execution, and the auxiliary monitoring system triggers the image acquisition equipment to link accordingly and forwards the video image recognition result to the one-key sequential control host computer as required. In this embodiment, after the verification is successful, the operation items of the single-step operation instruction are required, and the auxiliary equipment monitoring system can obtain a video image by triggering the linkage of the image acquisition equipment and can identify the video image to obtain a video image identification result so as to reflect the equipment state of the corresponding equipment.
In order to ensure the normal operation of the one-key sequential control and enable the one-key sequential control operation to meet the one-key sequential control technical requirement, as shown in fig. 9, in the whole process of the one-key sequential control, the video master station can display corresponding equipment operation videos according to linkage information and return image identification results to the centralized control system, so that information interaction between the centralized control system and the video master station is realized.
In the method, in the one-key sequential control process, a control command is transmitted to a transformer substation end through a master station, and the transformer substation end transmits process data executed by the command to the master station, so that the information interaction process between the master station and the transformer substation end is realized, and in the transformer substation end, the one-key sequential control process is realized through the information interaction process between a one-key sequential control host and an intelligent error prevention host as well as between the one-key sequential control host and a spacer layer device, namely, the method avoids the condition that the existing one-key sequential control technology is only the information interaction process of a single centralized control station end, operation and maintenance Ban Duan and the transformer substation end, but the information interaction process between the existing ends is realized, and the one-key sequential control is realized through the information interaction process between each device of the specific transformer substation end, so that the method accords with the current one-key sequential control technology requirements. In the method, the error-proof verification of the simulated replay process is based on the double error-proof verification processes of the verification of the error-proof verification host and the autonomous verification of the one-key sequential control host, so that the obtained verification result is more reliable. Compared with the prior one-key sequential control technology, the information interaction of the monitoring host, the spacer layer, the operation and maintenance class, the error prevention system and the auxiliary equipment monitoring system is only carried out, and the information interaction flow in the master station mode comprises information interaction of the centralized control system and the intelligent error prevention host, information interaction of the intelligent error prevention host and the station end error prevention host, information interaction of the centralized control system and the intelligent gateway machine and information interaction of the centralized control system and the video master station. The previous one-key sequential control is not interacted with the centralized control system, and the information interaction of the centralized control station end, the operation and maintenance Ban Duan and the transformer substation end penetrates through the whole one-key sequential control process under the new technical requirement of the one-key sequential control technology master station mode, so that the method of the invention meets the new technical requirement.
