Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a method for determining data abnormality of a telemechanical device according to an embodiment of the present invention, where the method is applicable to determining data transmission conditions between a master station of a scheduling center and telemechanical devices of a power station and a substation, and the method can be executed by a telemechanical device data abnormality determining device, and specifically includes the following steps:
and 110, collecting a multi-frame initial message returned by the telecontrol equipment, wherein the telecontrol equipment is arranged in a power plant or a transformer substation and is used for realizing the collection, measurement and monitoring of the operation data of the power equipment of the power plant or the transformer substation.
In this embodiment, the remote control refers to the application of remote communication technology to monitor and control the remote operating device, so as to implement various functions such as remote measurement, remote signal, remote control and remote adjustment. In the automated implementation of electric power systems, telemechanical control techniques play a crucial role. The specific telemechanical control is realized mainly by a master station arranged in a dispatching center and power stations and substations arranged in power stations and transformer substations through a data acquisition technology, a channel coding technology and a communication transmission technology. The telecontrol equipment converts the operating conditions (including on-off states, operating parameters of the equipment and the like) of each power plant, power supply station and transformer substation into a signal form convenient for transmission, adds a protection measure to prevent external interference in the transmission process, and transmits the signal form to the dispatching center through a special information channel after modulation. The main station of the dispatching center is subjected to inverse modulation, and is restored to be signals corresponding to the working conditions of a power plant, a power supply station and a transformer substation, and then the signals are displayed for monitoring by dispatching personnel. Some control commands of the dispatching personnel can also be transmitted to remote power plants, power stations and substations through similar processes to drive controlled objects.
Secondly, due to the characteristics of power production, information exchange among power plants, substations and dispatch centers can only be realized through channels. And the information transfer can only be in a serial manner. Therefore, in order to identify, receive and process the transmitted information after reaching the other party, strict specifications are made on the format of the transmitted information, which is one of the contents of the telecontrol protocol. These specifications include whether the mode of transmission is synchronous or asynchronous, frame sync words, interference-free measures, bit sync mode, frame structure, information transmission process. The common protocol in the power industry is the IEC protocol, which mainly includes the IEC-101/102/103/104 protocol, and in the process of transmitting information, data is encoded into messages according to the convention of the IEC protocol, and the messages are transmitted to each other in the form of a message, and each message is a frame.
In this embodiment, the provided method for judging data abnormality of a telecontrol device is mainly applied to a master station of a scheduling center, where the collecting of a multi-frame initial message returned by the telecontrol device refers to a message returned by the telecontrol device in response to an instruction of the master station received at the master station, and it should be noted that in the collecting process, a continuous message should be collected as the initial message in this embodiment, so as to avoid an error phenomenon caused by missing part of the message in the collecting process.
Optionally, the collection of the message may be to receive the message returned by the remote equipment in real time, or to directly collect the message sent by the remote equipment at the remote equipment end, or to read the message received by the host within a certain time period, which is not further limited herein as long as the message required in this embodiment can be obtained. In addition, in order to ensure real-time judgment of data transmitted by the telecontrol equipment, a real-time acquisition and analysis mode can be adopted to obtain the message.
Step 120, determining the initial type of the initial message.
The messages transmitted among the power plant, the substation and the dispatching center have various different types, and are respectively used for information transmission under different conditions, so that the information transmission of different types is realized. For example: the messages can be divided into correct messages and error messages according to the correctness of the messages; according to the action of the message, the method can be divided into an initialization message, a time synchronization message, a total calling message, a remote control message, a remote signaling message, a remote measuring message and a remote pulse message.
In this embodiment, the initial type of the initial packet is determined, that is, the correctness and other action types of the initial packet are determined. The specific confirmation method can determine according to the characteristic values in different types of initial messages, for example, determine the correctness of the initial message through frame check in the message, determine whether the message is an error message, and further determine which type of the initial message is an initialization message, a time synchronization message, a total call message, a remote control message, a remote communication message, a remote measurement message, or a remote pulse message according to the type identification bits of the non-error message, thereby confirming the initial type of the initial message.
And step 130, acquiring the characteristics which are matched with the initial type of the multi-frame initial message and have continuity.
In the present embodiment, the initial packets exist as a plurality of consecutive frames, where the initial types of some consecutive initial packets may be the same, and the continuous characteristic mentioned in the present embodiment that matches the initial type of the multi-frame initial packet means the number of initial packets and the initial type characteristic that occur consecutively in the consecutive multi-frame initial packets and have the same initial type. In other words, it is necessary to find initial packets with the same continuous initial types from consecutive multi-frame initial packets, and obtain the initial types and the continuous number corresponding to the initial packets.
And 140, if the characteristics are consistent with the preset target type, judging that the data returned by the telecontrol equipment is abnormal.
In this embodiment, the preset target type refers to a type corresponding to an initial packet of data exception returned by the telecontrol apparatus. That is, when the initial message of the type continuously appears, the data returned by the telecontrol equipment is abnormal, and the communication abnormality between the telecontrol equipment and the master station is represented. In other words, when the initial message corresponding to the target type continuously appears, the communication between the telecontrol equipment and the master station is abnormal, the telecontrol equipment is in a false online state, and the data returned by the telecontrol equipment is abnormal.
In the method for judging the data abnormality of the telemechanical equipment provided by the embodiment, continuous multiframe initial messages returned by a master station of a telemechanical equipment response scheduling center set by a power plant or a transformer substation are collected, then the initial types corresponding to the initial messages are determined, the characteristic of representing the continuity of the initial types of the continuous multiframe initial messages is obtained, the initial messages can be rapidly classified, the initial messages with the same continuous initial types in the initial messages are selected, and therefore the data analysis amount is effectively reduced; compared with the mode of manually analyzing and judging the result after the initial message is analyzed manually, the workload of monitoring personnel can be effectively reduced, then the collected initial message can be analyzed more timely to judge whether the data returned by the telecontrol equipment is abnormal, and further the monitoring personnel can be assisted to monitor the running states of the telecontrol equipment and the main station.
Example two
A second embodiment of the present invention provides another method for determining data abnormality of a telecontrol apparatus, fig. 2 is a flowchart of the method for determining data abnormality of a telecontrol apparatus according to the second embodiment of the present invention, which is further detailed based on the first embodiment, and describes a data processing process in detail, as shown in fig. 2, the method includes:
step 201, sending a query message to the telecontrol equipment in a polling manner.
The telecontrol equipment is arranged in a power plant or a transformer substation and used for realizing the operation data acquisition, measurement and monitoring of power equipment of the power plant or the transformer substation.
Step 202, receiving an initial message returned by the telecontrol equipment responding to the query message.
In this embodiment, the master station of the scheduling center sends the query message to the telecontrol equipment installed in the power plant, the power supply station, and the substation in a polling manner, and the telecontrol equipment installed in each power plant, power supply station, and substation will respond to the query message and return to the initial message required in the method for determining the abnormal data of the telecontrol equipment described in this embodiment after receiving the query message sent by the master station.
In other embodiments, the query message may be sent in other manners, or a message generated in the normal working process of the master station and the telecontrol equipment may be directly collected as a required initial message. The key point in this embodiment is the acquisition of the initial packet, and the specific acquisition manner is a common technique in the art and will not be described herein.
Step 203, obtaining a type identifier from the initial message, where the type identifier is used to indicate an initial type of the initial message.
The data in the message are arranged according to a certain frame structure, and a common protocol in the power industry is an IEC (international electrotechnical commission) protocol which mainly comprises an IEC-101/102/103/104 protocol, so that the initial type to which the initial type belongs can be judged from the data corresponding to the type identification bits in the message, and the message is further divided into different initial types according to the types represented by different type identifications. Furthermore, the correctness of the initial message can be judged through the frame checksum bits, and the error message is marked as an error type.
In a specific embodiment, step 203 comprises:
step 2031, obtain the initial frame checksum from the message tail of the initial message.
The frame checksum is a value set for judging whether the message is affected by external influence and has changed its value or abnormal phenomena such as frame loss and frame break, and can be used for judging whether the message is correct or not. For example, in the IEC-101/104 specification, a one-byte frame checksum bit is provided at the end of a message, and its value represents the frame checksum, i.e., the sum of the data calculated at the sender of the message except for itself.
Step 2032, calculating the check value of the initial message, where the check value is the sum of the initial message excluding the initial frame checksum.
In this embodiment, the frame checksum bits are summed with other data except for the frame checksum bits themselves, so that the same rule needs to be followed for calculation when calculating the checksum value, and the calculation manner of the check value is different from that of the frame checksum, so that the calculated checksum value is not comparable to the frame checksum, and whether the packet is damaged cannot be correctly determined.
Step 2033, comparing the initial frame checksum with the check value;
when the checksum of the initial frame is not equal to the check value, performing step 2034;
when the initial frame checksum and the check value are equal, step 2035 is performed;
step 2034, judging the initial type of the initial message as an error message;
step 2035, obtain the type identifier from the header of the initial packet.
In this embodiment, when the obtained initial frame checksum is not equal to the calculated check value, it represents that the message may be affected by external influences to change its own value or change the value set by abnormal phenomena such as frame loss and frame break, i.e. there is a possibility of data error in the corresponding initial message. At this time, the corresponding initial message is defined as an error message to mark the error initial message.
And when the obtained initial frame checksum is equal to the calculated check value, the data of the message is correct, the message is effective, and at the moment, the message header of the initial message is read, and the type identifier in the message header is read, so that the initial type of the message is obtained.
Step 204, intercepting the specified number of continuous initial messages as target message segments.
The specified number may be selected according to actual situations, for example, continuous 10 or 20 frames of initial messages are selected as the target segments required by this embodiment.
Step 205, comparing the number of initial messages with the initial type of error messages with a preset numerical value;
if the number is greater than or equal to the value, go to step 209.
In step 205, the number of initial type bit error messages in the intercepted specified number of initial messages needs to be obtained, and then the obtained number is compared with a preset numerical value, so as to determine whether the number of error messages in the intercepted specified number of initial messages exceeds the number in a normal working state, and further determine whether data returned by the telecontrol equipment is normal.
In other embodiments, the proportion of the error messages in the intercepted specified number of initial messages may be calculated, and then compared with the maximum proportion of the error messages in the normal working state, so as to determine whether the data returned by the telecontrol equipment is abnormal.
And step 206, arbitrarily intercepting at least two continuous initial messages as target message segments.
In this embodiment, the intercepting manner for the initial packet in step 206 is similar to the intercepting manner in step 204, and specifically, the intercepting manner in step 204 may be referred to. The message intercepting length in step 206 may be determined according to the number of the same initial type that is commonly found when the data returned by the telecontrol equipment is abnormal, for example, when two identical initial types representing faults are continuously returned, the communication between the telecontrol equipment and the master station is in an abnormal state, and at this time, the word intercepting length in step 206 may be set to two bits, that is, two continuous initial messages are intercepted as the target message segment. In addition, it should be understood that the two consecutive initial messages illustrated herein are only for illustration, and in other embodiments, the two consecutive initial messages may have interception lengths of three, four, five, and the like.
And step 207, when the initial types of the target segments are the same, taking the initial types of the target segments as characteristics.
The function in step 207 is to determine whether the initial types of the initial messages in the single target segment are the same, and if the initial types of the initial messages are the same, it means that the initial types of the initial messages in the specified length of the intercept are the same.
Step 208, comparing the characteristics with preset target types;
when the feature is the same as the target type, go to step 209;
when the feature is not the same as the target type, go to step 210;
and step 209, judging that the data returned by the telecontrol equipment is abnormal.
And step 210, judging that the data returned by the telecontrol equipment is normal.
When the initial type of the initial message in the target message segment is the same and is the same as the preset target type, it indicates that the data returned by the telecontrol equipment is abnormal, and the data returned by the telecontrol equipment has long-continuity data with the same initial type, which indicates that the telecontrol equipment may be in a state of no data or returning false data. In other words, the master station queries data from the telecontrol equipment during the normal operation of the telecontrol equipment, the data returned by the telecontrol equipment does not have initial messages with the same continuous target type exceeding a certain length under normal conditions, and when the initial messages occur, the telecontrol equipment is in a state of no data or false data return. In this embodiment, whether the initial packet of the target type that should not continuously appear continuously appears is determined mainly based on the determination of the continuity of the initial type of the received initial packet and by comparing the initial packet with the preset target type, that is, whether the data of the remote device is abnormal is determined.
In this embodiment, the correctness of the initial message is verified first, so as to determine the error message in the initial message, and whether the telecontrol equipment data is abnormal is determined by the proportion of the error message, so that the telecontrol equipment data abnormal form with a large number of error messages can be eliminated, and the subsequent calculation amount is effectively reduced. Then, the initial type corresponding to the initial message is determined, then, the initial messages with the same initial type within the specified length are screened out as the characteristic of the abnormal data of the telecontrol equipment provided in the embodiment, and finally, the initial messages are compared with the preset target type to judge whether the initial messages with the same continuous length and the initial types are normal or not.
