Such faults in the field of power transmission and distribution are of large social extent, often power outages around areas of several square kilometers, and are long, often requiring at least several hours, and seriously requiring several days, to be resolved. Therefore, the development and application of real-time temperature monitoring in the field are particularly important for controlling the occurrence and the diffusion of faults by attracting attention of relevant personnel early and effectively intervening in advance.

Referring to fig. 3, fig. 3 is a flowchart of a remote communication temperature measurement processing method based on a high-voltage ring main unit according to the present invention, where the remote communication temperature measurement processing method includes the following steps:

step S310, acquiring a temperature monitoring instruction for the high-voltage ring main unit; the temperature monitoring instruction is used for indicating a target front-end acquisition node which is indicated by the central control node to execute temperature information acquisition at present, and the target front-end acquisition node is one of the front-end acquisition nodes.

In this embodiment, when a maintainer at the side of the central control node needs to process temperature information of a certain high-voltage ring main unit, the maintainer at the side of the central control node may determine a front-end acquisition node corresponding to the high-voltage ring main unit as a target front-end acquisition node among the plurality of front-end acquisition nodes in a manner of manual confirmation, and input node information of the target front-end acquisition node to the central control node, so that the central control node executes the remote communication temperature measurement processing method provided by the present invention according to the temperature information acquired by the target front-end acquisition node.

Step S320, according to the temperature monitoring instruction, a control end data storage container is locally established in the central control node, and a container establishing instruction is sent to the target front-end acquisition node; the container creating instruction is used for instructing the target front-end acquisition node to create an acquisition-end data storage container locally at the target front-end acquisition node.

Step S330, when the creation of both the control end data saving container and the acquisition end data saving container is completed, a data interaction link and an interaction security key between the control end data saving container and the acquisition end data saving container are established.

In this embodiment, when the target front-end collection node completes creating the collection-end data saving container, the target front-end collection node may send a confirmation message to the central control node to feed back that creating of the collection-end data saving container is completed.

Correspondingly, when the central control node receives the confirmation information, the central control node confirms that the creation of the data saving container of the acquisition terminal is completed, and then the central control node establishes a data interaction link and an interaction security key between the data saving container of the control terminal and the data saving container of the acquisition terminal, wherein the data interaction link is used for data transmission between the data saving container of the control terminal and the data saving container of the acquisition terminal, and the interaction security key is used for security encryption when data transmission is performed between the data saving container of the control terminal and the data saving container of the acquisition terminal.

Step S340, acquiring temperature information with the target front-end acquisition node through the data interaction link and the interaction security key, and calculating a temperature change condition between the temperature data locally recorded by the central control node and the temperature data acquired by the target front-end acquisition node based on the acquired temperature data.

In this embodiment, after the data interaction link is constructed, the central control node may acquire temperature information through the data interaction link and the target front-end acquisition node, and process the acquired temperature data based on the calculation capability of the central control node, so as to calculate a temperature change condition between the temperature data locally recorded by the central control node and the temperature data acquired by the target front-end acquisition node. The temperature data locally recorded by the central control node may be historical data sent by the target front-end collection node, and the temperature change condition may be used to indicate a working state of the high-voltage ring main unit corresponding to the target front-end collection node; if the temperature change condition is large, for example, exceeds a set threshold range, the high-voltage ring main unit corresponding to the target front-end acquisition node is represented to be abnormal in work, for example, abnormal in temperature; and if the temperature change condition is within a set threshold range, representing that the high-voltage ring main unit corresponding to the target front-end acquisition node works normally.

Therefore, based on the above scheme provided by the present invention, after the central control node obtains the temperature monitoring instruction, by responding to the temperature monitoring instruction, locally creating a control end data saving container at the central control node, and after locally creating an acquisition end data saving container at the target front end acquisition node by the target front end acquisition node, constructing a data interaction link and an interaction security key between the service end data saving container and the acquisition end data saving container, so as to perform temperature information acquisition with the target front end acquisition node through the data interaction link and the interaction security key, and further obtain the temperature change condition of the high voltage ring main unit corresponding to the target front end acquisition node; compared with the prior art, the temperature change condition of each high-voltage ring main unit can be monitored in the monitoring system of the large-scale high-voltage ring main units respectively, the mutual pollution of data among different high-voltage ring main units is avoided, and the accuracy is improved.

In this embodiment, in order to accurately calculate a temperature change between the temperature data locally recorded by the central control node and the temperature data collected by the target front-end collection node, when the central control node executes step S340, the central control node may exchange a data record summary of the temperature data stored in the central control node and the target front-end collection node through the data interaction link; the data record abstract comprises the data packet size of first temperature data locally stored by the central control node and the data packet size of second temperature data acquired by the target front-end acquisition node; then, comparing the size of the data packet of the second temperature data with the size of the data packet of the first temperature data to determine a node data acquisition mode corresponding to the target front-end acquisition node; and then, according to the data interaction link, the control end data storage container and the interaction security key, adopting data processing contents corresponding to the current node data acquisition mode of the target front end acquisition node, preprocessing temperature information with the target front end acquisition node, and calculating the temperature change condition between the temperature data locally recorded by the central control node and the temperature data acquired by the target front end acquisition node based on the preprocessed temperature data. Therefore, different processing can be performed on the temperature data under different scenes based on different node data acquisition modes, and the accuracy of data processing is improved.

In this embodiment, when determining the node data acquisition mode of the target front-end acquisition node, the central control node may first calculate a relative ratio between a size of a data packet of the second temperature data and a size of a data packet of the first temperature data of the central control node; when the relative ratio does not exceed a preset ratio threshold, determining that a node data acquisition mode of the target front-end acquisition node is an asynchronous data acquisition mode; and when the relative ratio exceeds the preset ratio threshold, determining that the node data acquisition mode of the target front-end acquisition node is a synchronous data acquisition mode. In this embodiment, the asynchronous data collection model may refer to collection at a set time step interval, and the synchronous data collection mode may refer to collection that is continuous in time sequence.

In addition, based on the determined node data acquisition mode, the central control node adopts data processing contents corresponding to the node data acquisition mode in which the target front-end acquisition node is currently located according to the data interaction link, the control-end data storage container and the interaction security key, the temperature information is preprocessed with the target front-end acquisition node, and when the temperature change condition between the temperature data locally recorded by the central control node and the temperature data acquired by the target front-end acquisition node is calculated based on the preprocessed temperature data, the node data acquisition mode of the target front-end acquisition node can be firstly selected, screening out a target temperature data set used for carrying out temperature information processing with the central control node from all temperature data acquired by the target front-end acquisition node, and determining the data processing content of the target temperature data set; then, according to the data processing content and the interactive security key, the first temperature data and the second temperature data of the target temperature data set are preprocessed through the data interactive link and the control end data storage container, and the temperature change condition between the temperature data locally recorded by the central control node and the temperature data acquired by the target front end acquisition node is calculated based on the preprocessed temperature data.

For example, in this embodiment, in order to perform data processing in combination with different node data acquisition modes, in the process that the central control node screens out a target temperature data set for performing temperature information processing with the central control node from all temperature data acquired by the target front-end acquisition node according to the node data acquisition mode of the target front-end acquisition node and determines data processing contents of the target temperature data set, when the node data acquisition mode of the target front-end acquisition node is an asynchronous data acquisition mode, all temperature data acquired in the asynchronous data acquisition mode are used as the target temperature data set for performing temperature information acquisition with the central control node, and the data processing contents of the target temperature data set are determined to be cross-interval processing; when the node data acquisition mode of the target front-end acquisition node is a synchronous data acquisition mode, screening out a preset number of temperature data from all temperature data acquired in the synchronous data acquisition mode to serve as a target temperature data set, and determining the data processing content of the target temperature data set to be sequential processing; when the node data acquisition mode of the target front-end acquisition node comprises the asynchronous data acquisition mode and the synchronous data acquisition mode, screening out a preset number of temperature data from all temperature data acquired in the synchronous data acquisition mode, taking the preset number of temperature data and all temperature data acquired in the asynchronous data acquisition mode as the target temperature data set, and determining the data processing content of the target temperature data set as fusion processing; the fusion processing is to perform cross interval processing on the temperature data acquired in the asynchronous data acquisition mode, and perform sequential processing on the temperature data acquired in the synchronous data acquisition mode after the cross interval processing is completed.
