Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a monitoring information data checking method based on a real-time message bus, which comprises the following steps as shown in figure 1:
firstly, establishing a message bus mapping channel between an automatic checking module of a main station end and a front application (the front application module is mainly used for data communication with a substation) of the main station end;
and monitoring the change condition of the message channel in real time. The bearer of the message bus is a message and consists of two parts: a message header and a message body. The message header mainly comprises the public information of each type of message, and the function completed by the message is analyzed from the information of the message header. The message header contains information such as the length of the message body, the message type, the event identifier, the domain, the state, the source task, the target task, the security code and the like. The message body is specific data information to be sent, and the message body defines respective data bodies for functions of different messages. The message header and the message body form a complete message.
The message bus mapping channel realizes information transmission in a publishing and subscribing mode, and realizes the message transmission between different nodes by a publisher of a message and a receiver of the message through a multicast or point-to-point technology. In the multicast mode, a message publisher publishes a message to each node in the same group, and a message agent of a receiving node transmits the message to the receiver through communication modes such as a shared memory and the like. The subscription and the publication of the message are interacted by adopting an M language structure mode, and M language is based on object-oriented data coding. In each message transmission, it contains type and structure information, so that the data volume of each transmission can be increased.
And step two, a data channel is established between the front application and the substation end for transmitting the monitoring information of the master station and the substation time, and the channel only carries out interactive transmission of the checking data and cannot cause interference to other functions of the system.
And step three, when monitoring and checking are carried out, the automatic checking module of the main station end sends a starting command to the front application through the message bus mapping channel, then the command is forwarded through the data channel to inform the sub-station to start monitoring information check and acceptance, the sub-station automatically triggers signals to be sent upwards according to the sequence of the check and acceptance point table, and the data sent upwards in the monitoring information comprises state quantity and analog quantity. The state quantities comprise state quantities including various signal quantities such as circuit breakers, isolating switches, grounding disconnecting switches, protection hard contact states, remote control switching signals, primary frequency modulation state signals and the like, and the analog quantities comprise data such as active power, reactive power, current, voltage, transformer gear, temperature, power grid frequency and the like of primary equipment (lines, transformers, buses, generators and the like).
And fourthly, starting to receive the preposed change message by the automatic checking module of the master station, and unpacking, converting and storing the received message data. For the processing of the state quantity, a one-bit binary number is usually used for representing, 1 represents closing (action/input), 0 represents opening (resetting/quitting), and for the double-bit remote signaling, the automatic judgment is carried out according to the states of the main remote signaling and the auxiliary remote signaling; the processing of the analog quantity comprises reasonability checking, filtering and null-shift processing.
And fifthly, the automatic checking module preferentially caches, intelligently sorts and checks the analyzed message data, compares the message data with a front check acceptance point table, and displays the comparison result in real time through an alarm interface. In the process of acceptance, error signals such as jitter signals, associated signals and the like generated by the substation easily interfere the process of acceptance, so that the signals need to be effectively screened and shielded to ensure the normal verification flow and logic of data. After receiving the analysis data, the monitoring information automatic checking module pushes the analysis data to a stack according to a first-in first-out principle to perform caching, and each piece of caching data is compared with adjacent signals according to a rule agreed in advance. In general, the substations transmit signals in strict order of point numbers, and if the point numbers are detected to be consistent in time but not continuous, the current signal is considered to be a false signal, and needs to be deleted from a buffer to filter out useless data. And checking the sorted and screened data with a preposed point table to check whether the number and the name of the point are consistent or not, and giving a prompt when the check result is inconsistent. The comparison rule of the state quantity is that the same point number needs to be checked twice continuously according to the way of first combination and then division; the analog quantity also needs to be checked twice, the first check value is the value corresponding to the point number, the second check value is the point number plus an offset, and the acceptance check is only calculated when the two checks are passed.
And finally, displaying the acceptance result in real time, evaluating and analyzing, and storing the acceptance result in a filing mode.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
