The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. It should be noted that in the device five-prevention control method provided in the embodiments of fig. 2 to fig. 4 of the present application, an execution main body is the measurement and control device 102, and may also be a device five-prevention control device, and the device five-prevention control device may be a part or all of the measurement and control device 102 through software, hardware, or a combination of software and hardware. In the following method embodiments, the following method embodiments are described by taking the example that the execution main body is the measurement and control device 102.

In an embodiment, as shown in fig. 2, a device five-prevention control method is provided, which relates to a specific process in which a measurement and control device performs five-prevention logic rule calculation on a target device according to a received device selection command, so as to execute a corresponding operation, and includes the following steps:

s201, determining target equipment according to a received equipment selection command, and acquiring a five-prevention logic rule of the target equipment; the equipment selection instruction is used for indicating the measurement and control equipment to carry out control operation on the target equipment; the five-prevention logic rule is used for representing the logic relation between the state of the target device and the states of other devices.

The device selection command refers to an instruction for determining that the target device performs remote control operation, and may carry information such as a target device number and a target device address, and the device selection command may be sent to the measurement and control device by a terminal or sent to the measurement and control device by a monitoring platform. The target device refers to a device to be remotely controlled to operate, and in general, in a five-prevention system, the target device is a primary device, such as a knife switch, a circuit breaker, and the like. The five-prevention logic rule refers to the state logic relationship between primary devices in a five-prevention system, the device state of one device may have a logic relationship with the device states of a plurality of other devices, and one device corresponds to one five-prevention logic rule for representing the logic relationship between the device and the other devices.

In this embodiment, the measurement and control device may receive a device selection command sent by the terminal or the monitoring platform through its own communication module, and determine the target device of the current control operation according to a device number or a device address in the device selection command, where the device number or the device address may be represented by a character string such as a number or a letter, and the device address may also be represented by a coordinate manner. For example, the device selection command may carry information with a device number of 001, the measurement and control device may determine the target device a according to the device number 001, at this time, the measurement and control device may obtain a five-prevention logic rule corresponding to the target device a from a logic relationship database of the measurement and control device through a five-prevention rule configuration management module of the measurement and control device itself, where the five-prevention logic rule of the target device a may be represented as "a & & B | | C", and the relationship may be understood as a relationship that a device state of the device a and a device state of the device B are in a logical and relationship, and meanwhile, the device state of the device B and the device state of the device C are in a logical or relationship, it should be noted that the device a, the device B, and the device C may belong to the same interval loop or may not belong to the same interval loop, which is not limited in this embodiment.

S202, if the five-prevention logic rule comprises other interval loop devices outside the control range of the measurement and control device, sending a cross-interval five-prevention logic calculation request to the monitoring platform according to a device selection instruction; and the cross-interval five-prevention logic calculation request is used for indicating the monitoring platform to determine the control state of the target equipment according to the equipment states of the equipment in other interval loops.

When the five-prevention logic calculation corresponding to the target device is performed, the device states of all devices involved in the five-prevention logic rule need to be acquired. The monitoring platform can collect, monitor and control all the devices of the interval loops in the transformer substation, and one measurement and control device is only responsible for collecting, monitoring and controlling the devices of one interval loop in a control range, namely the measurement and control device of the interval loop a does not have the device for collecting, monitoring and controlling the interval loop b or other interval loops. If the five-prevention logic rule corresponding to the target device includes devices outside the control range of the current measurement and control device, the measurement and control device has no authority to acquire the device states of other interval loops, namely, the measurement and control device cannot perform cross-interval five-prevention logic calculation, and at the moment, the measurement and control device can selectively send a cross-interval five-prevention logic calculation request to the monitoring platform.

In this embodiment, in one of the cases, for example, the five-prevention logic rule of the target device a is "a & & B | | C", the device B and/or the device C and the target device a do not belong to the same interval loop, that is, the device B and/or the device C do not belong to the control range of the current measurement and control device, at this time, the measurement and control device may invoke its own communication module to send a cross-interval five-prevention logic calculation request to the monitoring platform, where the cross-interval five-prevention logic calculation request may be in the form of a GOOSE message, and the cross-interval five-prevention logic calculation request may carry information such as a device number of the target device, a device address of the target device, and the like, so that the monitoring platform obtains the five-prevention logic rule corresponding to the target device according to the device information of each device in the five-prevention logic rule, thereby obtaining the device state corresponding to each device, and completing the five-prevention logic calculation corresponding to the target device to obtain the control state of the target device, which is not limited in this embodiment.

And S203, receiving a request response returned by the monitoring platform.

The request response is a response which is sent by the monitoring platform and is aimed at the cross-interval five-prevention logic calculation request, the request response can be a receiving response or a refusing response, and the request response can be judged to be a receiving response or a refusing response by judging whether the monitoring platform carries the control state of the corresponding target equipment after the five-prevention logic calculation is carried out; the request response can also be judged as a receiving response or a refusing response by judging the request identification in the request response.

In this embodiment, the measurement and control device may receive, through the communication module, a request response of the cross-interval five-prevention logic calculation request sent by the monitoring platform, where one of the two situations exists is that the measurement and control device receives the request response without carrying a control state of the corresponding target device after the monitoring platform performs the five-prevention logic calculation, or a request identifier in the received request response is a reject response, for example, the request identifier is FALSE; in another case, the request response received by the measurement and control device carries the control state of the corresponding target device after the monitoring platform performs the five-prevention logic calculation, or a request identifier in the received request response is a received response, for example, the request identifier is TRUE, which is not limited in this embodiment.

And S204, if the request response comprises the control state of the target equipment, executing corresponding operation on the equipment according to the control state of the target equipment.

Wherein, the control state of the target device means that the target device is allowed to be controlled or the target device is not allowed to be controlled.

In this embodiment, if a request response received by the measurement and control device carries a control state of the target device, it indicates that the monitoring platform has responded and completed cross-interval five-prevention logic calculation sent by the current measurement and control device, at this time, the measurement and control device may execute corresponding operations on the device according to the control state of the target device, for example, if the control state of the target device is control disallowance, that is, lock control, and the control operation of the current measurement and control device on the target device fails, at this time, the measurement and control device may return to execute a received device selection command, and determine the target device according to the received device selection command. If the control state of the target equipment is allowed to be controlled, the measurement and control equipment can receive an execution command of the target equipment, which is sent by a terminal or a monitoring platform, wherein the execution command can be that the target equipment is turned on or turned off, and the measurement and control equipment carries out control operation of the target equipment according to the execution command; or, the measurement and control device performs corresponding control operation on the target device according to the execution information in the received device selection command, which is not limited in this embodiment.

In the device five-prevention control method, the measurement and control device determines the target device according to the received device selection command, and obtains a five-prevention logic rule of the target device for representing the logic relationship between the state of the target device and the states of other devices, if the five-prevention logic rule includes devices of other interval loops outside the control range of the measurement and control device, the measurement and control device sends a cross-interval five-prevention logic calculation request to the monitoring platform according to the device selection command to indicate the monitoring platform to determine the control state of the target device according to the device states of the devices of other interval loops, so that the measurement and control device receives a request response returned by the monitoring platform, and if the request response includes the control state of the target device, the measurement and control device executes corresponding operation on the device according to the control state of the target device. According to the method, the measurement and control equipment sends the cross-interval five-prevention logic calculation request to the monitoring platform, so that the transverse cross-interval five-prevention logic calculation can be completed in the monitoring platform, equipment information and equipment five-prevention logic rules of other transverse interval loops are not required to be configured in the current measurement and control equipment, and the measurement and control equipment is only configured with the equipment information and the equipment five-prevention logic rules of the current interval loops and cannot be influenced by other interval loops which are reconstructed or expanded when a transformer substation is reconstructed and expanded.

In another case, all the devices in the five-prevention logic rule corresponding to the target device, which is acquired by the measurement and control device, are in the interval loop of the target device a, in an embodiment, as shown in fig. 3, the method further includes:

s301, if the five-prevention logic rule does not include other interval loop devices outside the control range of the measurement and control device, performing current interval five-prevention logic calculation on the target device according to the five-prevention logic rule to obtain the control state of the target device.

The device not including other interval loops outside the control range of the measurement and control device in the five-prevention logic rule means that all devices in the five-prevention logic rule corresponding to the target device a are in the control range of the current measurement and control device, that is, the interval loops of all the devices are consistent with the interval loops of the target device a.

In this embodiment, the measurement and control device has the right to acquire, monitor, and control the devices in the current interval loop, that is, the measurement and control device may obtain the real-time states of all the devices in the five-prevention logic rule, so that the current interval five-prevention logic calculation of the target device a may be performed according to the real-time states of all the devices and the five-prevention logic rule, and a calculation result corresponding to the control state of the target device a is obtained.

And S302, executing corresponding operation on the equipment according to the control state of the target equipment.

In this embodiment, if the control state of the target device is allowed to be controlled, at this time, the measurement and control device may perform the control operation of the target device by receiving an execution command of the target device sent by the terminal or the monitoring platform, where the execution command may be that the target device is turned on or that the target device is turned off, and the measurement and control device performs the control operation of the target device according to the execution command; or, the measurement and control device performs corresponding control operation on the target device according to the execution information in the received device selection command, which is not limited in this embodiment.

In the embodiment, the measurement and control equipment only needs to carry out five-prevention logic calculation and remote control on the equipment in the control range, so that the calculation resource is saved, and the interaction and control safety of the longitudinal equipment is enhanced.

Specifically, in an embodiment, as shown in fig. 4, the performing, according to the five-prevention logic rule, the current interval five-prevention logic calculation on the target device to obtain the control state of the target device includes:

s401, obtaining the device state of each device in the five-prevention logic rule.

The five-prevention logic rule is a logic relationship between the device state of the target device a and the device states of other devices, and for the primary device in this embodiment, the device state at least includes two states, namely, a device on state and a device off state.

In this embodiment, the measurement and control device collects real-time state information corresponding to all devices in the five-prevention logic rule according to device information, such as device numbers and device addresses, of the devices included in the five-prevention logic rule. Preferably, the state identifier of the device on may be set to be 1, the state identifier of the device off may be set to be 0, and the measurement and control device may store the acquired state identifiers of all the devices in a memory thereof for performing five-prevention logic calculation, which is not limited in this embodiment.

S402, performing five-prevention logic calculation according to the five-prevention logic rule and the equipment state of each equipment to obtain the control state of the target equipment.

In this embodiment, as illustrated in the same example above, the five-prevention logic rule corresponding to the target device a may be "a & & B | | C", the device state of the target device a acquired by the measurement and control device is device on, the corresponding state identifier thereof is 1, the acquired device state of the device B is device off, the corresponding state identifier thereof is 0, the device state of the device C is device on, the corresponding state identifier thereof is 1, at this time, the state identifier of each device is substituted into the five-prevention logic rule, that is, "1 & &0| | 1", and the calculation result of the five-prevention logic rule is 1, and preferably, the measurement and control device may set that when the calculation result of the five-prevention logic rule is 1, the control state of the target device a is allowed to be controlled; on the contrary, when the five-prevention logic rule calculation result is 0, the control state of the target device a is not allowed to be controlled; optionally, the five-prevention logic rule calculation result may also be represented by a character "TRUE" or "FALSE", and when the five-prevention logic rule calculation result is "TRUE", the control state of the target device a is allowed to be controlled; on the contrary, when the result of the five-prevention logic rule calculation is "FALSE", the control state of the target device a is not allowed to be controlled, which is not limited in this embodiment.

In this embodiment, the measurement and control device completes the five-prevention logic calculation and the remote control of the target device by acquiring the device state of the device within the control range, and only performs the five-prevention logic calculation and the remote control of the device within the control range, thereby saving the calculation resources to a certain extent.

After the measurement and control device obtains the control state of the target device, since the control state of the target device may have a plurality of situations, in an embodiment, the performing corresponding operations on the device according to the control state of the target device includes:

if the control state of the target equipment is a first value, returning to execute the step of receiving the equipment selection command, and determining the target equipment according to the received equipment selection command; the first value indicates that the target device is in a non-control state.

The first value refers to a state that the target device is not allowed to be controlled, and the first value may be a number or a character, for example, the first value may be represented by "0" or "FALSE".

In this embodiment, for example, the control state of the target device acquired by the measurement and control device is "0" or "FALSE", which indicates that the current target device is not allowed to be controlled to execute any operation, at this time, the measurement and control device interrupts the current operation, re-receives the device selection command, determines the target device according to the received device selection command, and performs the next device control operation, which is not limited in this embodiment.

The second value refers to a state that the target device is allowed to be controlled, and the second value may be a number or a character, for example, the second value may be represented by "1" or "TRUE".

In this embodiment, exemplarily, the control state of the target device acquired by the measurement and control device is "1" or "TRUE", which indicates that the current target device is allowed to be controlled for remote operation, at this time, the measurement and control device may receive an execution command of the target device sent by the terminal or the monitoring platform, where the execution command may be to turn on or turn off the target device, and the measurement and control device performs a control operation of the target device according to the execution command; or, the device selection command received by the measurement and control device carries execution information, and the measurement and control device may perform corresponding control operation on the target device according to the execution information, which is not limited in this embodiment.

In this embodiment, the measurement and control device needs to determine whether the target device is allowed to be remotely controlled according to the five-prevention logic rule of the target device, and performs corresponding operation according to the control state obtained by calculation of the five-prevention logic rule, thereby avoiding misoperation on the target device.

When the measurement and control equipment receives a request response of the cross-interval five-prevention logic rule calculation request sent by the monitoring platform, another situation may exist, and in one embodiment, the method further includes:

In this embodiment, the request response received by the measurement and control device does not include the control state of the target device, and preferably, the request identifier of the request response may be FALSE, at this time, it may be considered that the monitoring platform cannot process the current cross-interval five-prevention logic calculation request, that is, the monitoring platform may be processing cross-interval five-prevention logic calculation requests of other measurement and control devices, or is in a busy stage, the measurement and control device cannot complete the current control operation of the target device, return to execute the received device selection command, and determine the target device according to the received device selection command, and perform the next device control operation, which is not limited in this embodiment.

In this embodiment, when the measurement and control device determines that the obtained request response does not include the control state of the target device, the current device control operation may be interrupted, and the current device control resource is released, so that the next device control operation is performed, and the device control efficiency of the measurement and control device is improved.
