Some low-voltage equipment and high-voltage equipment belong to the same category, and have basically the same function in a circuit, but have different names, such as a low-voltage circuit breaker called an automatic switch and a disconnecting switch called a knife switch. Common low-voltage rubber cover switches, steel shell switches, change-over switches, contactors and the like belong to the class of load switches, and only some switches are added with some functions. For example, some transfer switches can switch power supplies, contactors are convenient for remote and automatic control, and the like.

The common message comprises 8583 messages formulated by Chinese Union of pay, each large bank and Union of pay carry out information transmission and follow the message, 64 fields are defined (each field is equivalent to a room and stores data such as price and name), support is extended to 128 fields, each field stores specific appointed content and format (can be searched on the internet), each industry also has self-defined messages, and a plurality of enterprises can also mutually appoint messages, the method includes the steps that character strings are established according to a message, a receiver analyzes an f character string according to rules to obtain transmitted information, the message is divided into a message header and a message body, the message header is a string of 16-system data, the message header is converted into a 2-system data to know which corresponding fields have data and which do not have data, 0 represents no, 1 represents a field, and for example, a string of message headers is 7B35. 0111101100111001 are omitted later, indicating 2345 fields have data, 6 do not, 78 do, 9, 10 fields do not, and so on. And then intercepting and then putting the intercepted data into an object according to the data length and the content of each field in the appointed document.

And S5, calculating the chopping time length by taking the automatic chopping time as the starting time, and controlling the communication to automatically recover and generate recovery reminding information when the chopping time length exceeds the preset recovery time length.

In one embodiment, the chopping time is calculated by a timer, when the timer reaches a preset time, a pulse signal can be generated, and after the server receives the pulse signal sent by the timer, the automatic recovery control of communication is carried out.

The automatic recovery of the communication can be realized by controlling a power supply main switch of the substation communication system, the power supply main switch controls the power supply of the whole substation communication system, and when the power supply main switch is closed, the whole substation communication system is powered on, so that the whole substation communication system is communicated for communication, and the communication is recovered. The power supply main switch adopts a remote control switch, after the server receives the pulse signal sent by the timer, the chopping time of the communication is shown to reach the preset time, at the moment, the remote control power supply main switch is closed to electrify the whole substation communication system, and the substation communication system is automatically recovered.

And S6, sending the recovery reminding information to the operation and maintenance terminal.

When the method is used, firstly, the initial measurement message information of the transformer substation communication system is obtained and analyzed, then the analyzed initial measurement message information is matched with the message rule, when the two can not be matched, the transformer substation communication system is indicated to have a fault, the communication is controlled to be automatically cut off and abnormal message reminding information is generated, the abnormal message reminding information is sent to an operation and maintenance terminal, so that the operation and maintenance personnel can know the fault, then, after the communication is cut off for a preset recovery time, the communication is controlled to be automatically recovered and recovery reminding information is generated, and finally, the recovery reminding information is sent to the operation and maintenance terminal, so that the operation and maintenance personnel do not need to spend a long time to drive a vehicle and rush to the site to complete simple communication cutting-off and recovery work, the method can automatically know that the transformer substation communication system has the fault and can solve the fault, and the operation and maintenance personnel can know the fault occurrence condition through the operation, therefore, the automatic chopping and recovery method of the intelligent substation communication system improves the speed of fault processing and reduces the consumption of manpower and material resources.

In an embodiment, a difference between this embodiment and the above embodiment is that, referring to fig. 2, step S1, acquiring and analyzing initial measurement message information of the substation communication system, specifically includes the following steps:

s101, acquiring initial test message information from a mirror image port of the switch.

The port mirroring function is to forward data traffic of one or more source ports to a certain designated port on a switch or a router to monitor the network, wherein the designated port is called a "mirroring port" or a "destination port", and the traffic of the network can be monitored and analyzed through the mirroring port without seriously affecting the normal throughput of the source ports. Therefore, the initial test message information can be obtained through the mirror image port of the switch.

In an embodiment, a difference between this embodiment and the above embodiment is that, referring to fig. 3, S2, the step of formulating the message rule in matching the analyzed initial measurement message information with the message rule includes:

s201, network equipment accessed to a network during normal operation of the transformer substation communication system is obtained.

The network equipment comprises primary equipment and secondary equipment. Primary equipment is electrical equipment that directly participates in the production, delivery and distribution of electrical energy. The secondary equipment monitors, controls and protects the working condition of the primary electrical equipment.

S202, acquiring a network protocol used by each network device for communication, wherein the same protocol needs to be acquired once.

I.e., all network protocols that traverse each network device, for any one protocol, if the rules for that protocol do not exist in the rule set, then the rules for that protocol are added to the rule set. A protocol may generate multiple rules based on different types of messages (e.g., different rules may be formulated for request messages and response messages). Each rule contains the following 4 aspects of features: port, address, message length, message content. If a certain aspect of the protocol cannot extract the features, the feature of the aspect is null, and if the message of the Mac layer protocol does not have the port number, the feature of the port is null. Wherein, the port refers to a port with a specific source or destination of the message; the address refers to that the destination address of the message of the broadcast protocol is in a specific range; the message length means that the message content has a fixed length or the length is within a certain range; the message content means that the values of some fields in the message content are fixed, and the fields are the characteristics of the message.

S203, referring to the established standards of respective protocols, and establishing one or more message rules for each protocol according to the port, address, length and content characteristics of the protocols.

These protocols are the protocols required for inter-device communication when routing.

When the method is used, the network equipment accessed to the network when the transformer substation communication system normally operates is firstly obtained, then the network protocol used by each network equipment for communication is obtained, the same protocol needs to be obtained once, then the formulation standard of each protocol is referred, one or more message rules are formulated for each protocol according to the port, address, length and content characteristics of the protocol, finally the message rules of common protocols are added, the added protocol is a general network protocol required by route discovery among equipment, the message rule of the transformer substation communication system in a normal operation state can be formulated, and therefore when the message information is not matched with the message rule, the fault of the transformer substation communication system can be known.

In one embodiment, referring to fig. 4, the difference between this embodiment and the above embodiment is that the method for automatically chopping and recovering the intelligent substation communication system further includes the following steps:

and S7, when the analyzed initial measurement message information cannot be matched with the message rule, marking the initial measurement message as an abnormal message.

When the analyzed initial measurement message information cannot be matched with the message rule, the substation communication system is not in a normal state at the moment, so that the message is an abnormal message, and the initial measurement message is marked as the abnormal message at the moment.

And S8, matching the abnormal message with the historical abnormal message in the abnormal message database.

The abnormal message database stores abnormal messages which are historically appeared.

When the abnormal message cannot be matched with the historical abnormal message in the abnormal message database, it indicates that the history of the abnormal message does not appear, and at this time, step S5 calculates the chopping time by using the automatic chopping time as the starting time, and after the chopping time reaches the preset recovery time and controls the automatic recovery of the communication and generates the recovery reminding information, the method further includes:

and S9, obtaining and analyzing retest message information after communication automatic recovery.

The method for acquiring and analyzing retest message information is the same as the method for initially measuring message information and analyzing the retest message information, the retest message information is acquired through a port mirror image function, the port mirror image function is used for forwarding data flow of one or more source ports to a certain specified port to realize network monitoring, the specified port is called as a mirror image port or a target port, and the network flow can be monitored and analyzed through the mirror image port under the condition that the normal throughput of the source ports is not seriously influenced. The mirror image function is used in the enterprise, network data in the enterprise can be well monitored and managed, and when the network fails, the fault can be quickly positioned.

And S10, matching the analyzed retest message information with the message rule.

The retest message information is obtained again after the automatic communication chopping and recovery, and the analyzed retest message information is matched with the message rule, so that whether the substation communication system with the fault is recovered to be normal or not after the automatic communication chopping and recovery can be known.

And S11, when the analyzed retest message information can be matched with the message rule, storing the abnormal message related to the retest message information into the abnormal message database.

When the analyzed retest message information can be matched with the message rule, the fault condition causing the abnormal message can be solved after the automatic communication chopping and recovery, at the moment, the abnormal message related to the retest message information is stored in the abnormal message database, when the abnormal message appears again, the communication is only required to be automatically chopped and recovered, and the retest is not required to be carried out again after the automatic communication chopping and recovery.

In practical use, when the analyzed initial measurement message information cannot be matched with the message rule, the substation communication system is not in a normal state, and the initial measurement message information is marked as an abnormal message. When the abnormal message can not be matched with the historical abnormal message in the abnormal message database, the abnormal message is described as an abnormal condition which has not occurred before, then after controlling the communication to automatically recover, the retest message information after the communication is automatically recovered is obtained again and analyzed, then matching the analyzed retest message information with the message rule, when the analyzed retest message information can be matched with the message rule, the abnormal message can be automatically recovered to the normal state through the automatic cutting and recovery of the communication, at the moment, the abnormal message is stored in the abnormal message database, when the same abnormal message appears again, only the automatic chopping and recovery of the communication are needed to be executed, and whether the abnormal message can be recovered to be normal after the automatic chopping and recovery of the communication is not needed to be detected again, so that the fault processing speed is improved.

In one embodiment, referring to fig. 5, the difference between this embodiment and the above embodiment is that the method for automatically chopping and recovering the intelligent substation communication system further includes the following steps:

and S12, generating difficult and complicated fault reminding information when the analyzed retest message information cannot be matched with the preset message rule.

When the analyzed retest message information cannot be matched with the preset message rule, the fault condition causing the abnormal message cannot be solved after the automatic communication chopping and recovery, and needs to be solved by operation and maintenance personnel, and a difficult fault reminding message is generated at the moment.

S13, sending the difficult and complicated fault reminding information to an operation and maintenance end so that the operation and maintenance personnel can rush to the site to solve the difficult and complicated fault.

After receiving the difficult and complicated fault reminding message through the operation and maintenance end, the operation and maintenance personnel can timely know that the problem which cannot be automatically chopped and restored through communication occurs, and at the moment, the operation and maintenance personnel can timely rush to the site to solve the fault.

In one embodiment, the difference between this embodiment and the above embodiment is that the method for automatically chopping and recovering the intelligent substation communication system further includes the following steps:

and S14, when the analyzed retest message information cannot be matched with the preset message rule, marking the retest message information as a difficult message.

When the analyzed retest message information cannot be matched with the preset message rule, the fault condition causing the abnormal message cannot be solved after the communication is automatically chopped and recovered, and the retest message information is marked as a difficult message.

S15, matching the difficult message with the historical difficult message in the difficult message library.

By the scheme, whether the same problematic messages appear before can be known.

And S16, when the difficult message is matched with the historical difficult message in the difficult message library, sending the difficult fault solution information associated with the historical difficult message to the operation and maintenance terminal.

When the problematic message is matched with the historical problematic message in the problematic message library, the same problematic message appears before, so that the situation that the problematic message is generated in the historical record at this time is possibly the same. For the problematic message which occurs once, the operation and maintenance personnel at that time have a solution when solving the problem at first, and at the moment, the operation and maintenance personnel send the problematic fault solution information associated with the historical problematic message to the operation and maintenance terminal, so that the operation and maintenance personnel at this time can check the solution adopted by solving the same problematic fault before through the operation and maintenance terminal, further, the problematic fault can be solved more quickly, and the problematic fault solving efficiency is improved.

When the method is used in practice, when the analyzed retest message information cannot be matched with the preset message rule, it is indicated that the abnormality represented by the abnormal message cannot be recovered to normal through automatic chopping and recovery of communication, at the moment, the retest message information is marked as a difficult message, then the difficult message is matched with the historical difficult message in the difficult message library, whether the same fault occurs before is judged, and when the difficult message is matched with the historical difficult message in the difficult message library, the difficult and complicated solution information related to the historical difficult and complicated message is sent to the operation and maintenance terminal, so that the operation and maintenance terminal can conveniently check the solution adopted for solving the same difficult and complicated fault before through the difficult and complicated solution information, further, the difficult and complicated fault can be solved more quickly, and the solution efficiency of the difficult and complicated fault is improved.

and S17, when the difficult message cannot be matched with the historical difficult message in the difficult message library, sending reminding information for reminding operation and maintenance personnel to input a difficult fault solution to the operation and maintenance terminal.

When the difficult message cannot be matched with the historical difficult message in the difficult message library, the fact that the difficult message which appears at this time does not appear in the history is shown, and related files are not stored in the difficult message library, so that reminding information for reminding operation and maintenance personnel to input a difficult and complicated fault solution is sent to an operation and maintenance end, and after the operation and maintenance personnel solve the fault which causes the difficult message, the operation and maintenance personnel can remember to enter the own solution in time through the operation and maintenance end, so that the maintenance can be facilitated when the same fault appears next time.

S18, receiving the solution information of the problematic fault corresponding to the problematic message and recorded by the operation and maintenance terminal.

The solution information of the problematic fault is the solution information adopted by the operation and maintenance personnel to solve the fault causing the problematic message.

S19, associating the problem message with the problem fault solution information which is recorded by the operation and maintenance terminal and corresponds to the problem message, and storing the associated problem message and the solution information into a problem message library.

Because the difficult message is correlated with the difficult fault solution information which is recorded by the operation and maintenance terminal and corresponds to the difficult message, when the same fault which causes the difficult message occurs again, the difficult fault solution information corresponding to the fault can be obtained, and therefore operation and maintenance personnel can improve the solution efficiency of the difficult fault.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the present invention.
