Detailed Description
The following describes in detail the embodiments of the present disclosure with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.
FIG. 1 is a flow chart illustrating a secondary device cooperation based anti-misoperation method applied to a secondary device cooperation based anti-misoperation system, according to an exemplary embodiment, the system comprising: the system comprises an anti-misoperation logic base, an information forwarding point table, an anti-misoperation host, a background host, primary equipment and secondary equipment, wherein the background host is connected with all the primary equipment and the secondary equipment on site, the anti-misoperation host is connected with the background host, the information forwarding point table is located in the background host, and the anti-misoperation logic base is located in the anti-misoperation host.
In step 101, status information of the primary device and the secondary device is collected by the background host, and the status information is sent to the error-preventing host in the form of an information forwarding point table.
For example, in general, in view of a dangerous environment of a substation, it is necessary to determine whether there is an erroneous operation before operating secondary equipment in the substation, and at this time, it is necessary to use a background host and an error prevention host. The background host is used for collecting the state information of the primary equipment and the secondary equipment and transmitting the state information to the error-preventing host in the form of an information forwarding point table. The error prevention host is arranged at an office place far away from the transformer substation, and an error prevention logic library is prestored in the error prevention host and is used for judging whether misoperation exists in the secondary equipment according to the state information.
For example, the information transfer point table may be represented by table 1:
TABLE 1
In step 102, during the simulation replay process of the secondary device by the anti-misoperation host, checking whether misoperation exists during the simulation replay process according to the state information and a preset anti-misoperation logic database.
The error-proof logic library also comprises interval analog quantity and interval alarm message of the secondary equipment.
The error prevention logic library is used for judging the state information of the secondary equipment according to preset error prevention logic, and determining whether misoperation exists in the operation process.
Further, the secondary device is a measurement and control device, and the checking of whether misoperation exists in the simulation replay process according to the state information and a preset anti-misoperation logic database includes: determining the number and the use state of each breaker in the measurement and control device and the number and the use state of each switch in the measurement and control device; and checking whether misoperation exists in the simulation replay process or not through a preset misoperation prevention logic database according to the number and the use state of each breaker and the number and the use state of each switch.
For example, if the secondary device is a measurement and control device, checking whether misoperation exists according to the use states of the circuit breakers and the switches in the secondary device acquired by the background host, wherein the secondary device comprises a plurality of circuit breakers and switches, so that the numbers of the circuit breakers and the switches also need to be determined.
Checking whether misoperation exists in the simulation replay process through a preset misoperation prevention logic database so as to determine whether to trigger alarm information of the secondary equipment or perform logic locking on the secondary equipment. When the functional pressing plate tries to withdraw, corresponding locking logic is popped up, and withdrawal prohibition operation is displayed.
Still further, the secondary device is a double-set protection device, and the checking of whether misoperation exists in the simulation replay process according to the state information and a preset anti-misoperation logic database includes: determining state information of primary equipment, and judging whether the double-set protection device exits according to the error prevention logic if the primary equipment is in an operation state; if the first set of protection devices are in the process of exiting operation, logically locking the exiting operation of the second set of protection devices to prohibit the exiting operation of the second set of protection devices; and if the withdrawal operation of the first set of protection devices is completed, performing simulated billing on the withdrawal operation of the second set of protection devices.
For example, during a double set protection operation, only one set of protection is allowed to exit when the device is running at a time, and the second set is prohibited from exiting when one set is exiting. And performing exit operation billing on the first set of line protection. In the process of analog billing, a popup prompt is provided that the operation can lead to single-set main protection operation of line protection, so that operators are reminded, the current interval is operation equipment, and the result of the analog operation can lead to a certain risk.
In addition, in the process of exiting operation of the second set of protection devices, acquiring state information of the first set of protection devices at intervals of a preset time period through the background host, and judging whether the first set of protection devices are in an operating state or not through the error prevention host; if the first set of protection devices are detected to be in the running state, the exit operation of the second set of protection devices is logically locked so as to inhibit the exit operation of the second set of protection devices.
The method further comprises the steps of: during the exit operation process of the second set of protection device, acquiring state information of the first set of protection device by the background host at intervals of a preset time period, and judging whether the first set of protection device is in an abnormal operation state or a device alarm state by the error prevention host; if the first set of protection devices are detected to be in abnormal operation or device alarm state, the exit operation of the second set of protection devices is logically locked so as to inhibit the exit operation of the second set of protection devices.
Illustratively, after the first set of protection invoices are completed, the second set of protection is subjected to an exit operation of the simulated invoices. The logical lock between the built-in double protection will prohibit the exit operation of the second protection. The system patrols and examines the first set of protection device, and if the function of the protection device is not complete or an abnormal signal exists, the system locks the exit operation of the second set of protection. Meanwhile, the system automatically patrols and examines the primary equipment at the interval, finds that the primary equipment is in an operation state, patrols and examines the line protection again, and after finding that the operation is carried out, the interval loses the protection operation, so that the second set of protection exit operation is blocked.
In step 103, if it is determined that there is a malfunction, the operation authority of the secondary device is closed by the malfunction prevention host.
In step 104, if there is no misoperation, the operation authority of the secondary equipment is opened through the error prevention host computer, and an operation ticket is sent to an operator.
In addition, the following examples are also made for the implementation of the functions of the error-proof host in the embodiment of the present invention:
as shown in fig. 2, after entering the software main interface, the device directories in the substation may be displayed, where the interval selection may be completed. Clicking a starting task menu after logging in the system, and clicking a starting task, so as to enter an invoicing page.
As shown in fig. 3, in the interval page, a directory of line interval devices in the substation is displayed, and the interface can complete the selection of the devices in the interval, so that the selected interval and the selected devices are accurate when secondary tickets are transmitted to the system.
As shown in fig. 4, the interface is simulated in the spaced platen state and operation. In the interface, accurate simulation operation can be carried out on the interval hard pressing plate, the soft pressing plate and the outlet pressing plate, and system operation ticket checking is completed. The device can conduct billing simulation previewing on primary equipment, can conduct billing simulation previewing on secondary equipment, and can conduct mixed previewing on the primary equipment and the secondary equipment.
As shown in fig. 5, when the simulation operation is performed on the hard pressing plate, the soft pressing plate and the outlet pressing plate at the interval in the interface, the logic verification is completed, the system operation ticket is completed, when the system monitoring device has an abnormal signal, the logic judgment is performed, the related pressing plate is locked for operation, and when the equipment operates normally, the system completes the control operation of each state of the equipment according to the logic judgment.
