[0002] In order to promote the transformation of the power grid to the goal of energy interconnection, sharing and mutual assistance, the concept of power Internet of Things is proposed.

[0051] Step 103: The power transmission monitoring data, the substation monitoring data and the cable monitoring data are analyzed using corresponding analytical models to obtain power transmission analytical data, substation analytical data and cable analytical data.

[0052] Step 104: According to the set IoT protocol transmission requirements, the power transmission analysis data, the substation analysis data and the cable analysis data are placed in a set general model, and the set general model is converted into standard data of the IoT model using the JSONObject tool class to obtain power transmission standard data, substation standard data and cable standard data.

[0053] Step 105: Determine the power transmission warning information of the power transmission monitoring data, the power transformation warning information of the power transformation monitoring data, and the cable warning information of the cable monitoring data by using a threshold judgment method.

[0054] Step 106: append the power transmission warning information to the power transmission specification data to generate power transmission data, append the substation warning information to the substation specification data to generate substation transmission data, append the cable warning information to the cable specification data to generate cable transmission data.

[0055] Step 107: Upload the power transmission data, the substation transmission data and the cable transmission data to the property management platform.

[0056] Wherein, step 101 specifically includes:

[0057] The TCP protocol is used to obtain the transmission monitoring data collected by the transmission status monitoring sensor on the target power grid; the TCP protocol is used to obtain the substation monitoring data collected by the substation status monitoring sensor on the target power grid; the TCP protocol is used to obtain the cable monitoring data collected by the cable status monitoring sensor on the target power grid.

[0058] Wherein, step 103 specifically includes:

[0059] The analysis model corresponding to the power transmission monitoring data is adopted to intercept the original hexadecimal power transmission message data of the power transmission monitoring data, and the tool class corresponding to the analysis model is adopted to perform base conversion on the original hexadecimal power transmission message data to obtain the power transmission analysis data.

[0060] The parsing model corresponding to the substation monitoring data is used to intercept the original hexadecimal substation message data of the substation monitoring data, and the tool class corresponding to the parsing model is used to convert the original hexadecimal substation message data to obtain the substation parsing data.

[0061] The original hexadecimal cable message data of the cable monitoring data is intercepted by using the parsing model corresponding to the cable monitoring data, and the original hexadecimal cable message data is converted into hexadecimal by using the tool class corresponding to the parsing model to obtain the cable parsing data.

[0062] Wherein, step 105 specifically includes:

[0063] It is determined whether the power transmission monitoring data, the substation monitoring data and the cable monitoring data exceed a set warning range to obtain a determination result.

[0064] Power transmission warning information, substation warning information and cable warning information are generated according to the judgment result.

It receives data from different monitoring sensors in a unified manner, performs early warning analysis according to thresholds and marks them uniformly. After conversion to a unified protocol that conforms to the IoT object model, it is uniformly reported to the platform layer and complies with the edge agent framework APP development specifications.

[0068] See also Figure 2 In practical applications, a specific implementation process of the above-mentioned unified protocol conversion and early warning analysis method based on edge agent is as follows:

[0069] Step 1: The power transmission, substation, and cable status monitoring sensors are connected to the edge agent's docker container through the TCP protocol. After the connection, the edge agent's docker container puts all device TCP connections into the connection pool for connection pool management, and puts the collection tasks into the task scheduling management, and regularly recalls sensor data through the TCP connection in the connection pool; at the same time, the protocol configuration management synchronizes the configured parsing model to the cache pool to implement cache management.

[0070] Step 2: After receiving the data, the task scheduler parses the data according to different parsing models in the cache pool, intercepts certain original hexadecimal message data, converts the data into different bases through a unified tool class, and obtains the corresponding parsed data results.

[0071] Step 3: Parse the results according to the IoT protocol transmission requirements, put the data into a common model, and use the JSONObject tool class to convert the common model into standard data of the IoT model.

[0072] Step 4: At this point, a threshold is used to determine whether each type of monitoring data exceeds the alarm / warning range, and the alarm / warning information is appended to the specification data.

[0073] Step 5: The unified standard data is then transmitted to the data transmission bus of the edge agent's Docker container through the MQTT protocol, and then sent to the property management platform through the unified interface of the edge agent's Docker container.

[0074] The edge agent-based unified protocol conversion and early warning analysis method of this specific example uniformly receives the data of power transmission, substation, and cable status monitoring sensors, parses different protocols according to the protocol type format issued by the protocol configuration module, and then converts the parsed results into standard data of the Internet of Things model in accordance with the Internet of Things protocol transmission requirements, and uniformly issues early warnings by pre-setting thresholds, and then transmits the unified standard data to the data transmission bus of the edge framework, and finally sends it to the property management platform through a unified interface.

[0075] The present invention has the following advantages: it solves the problem of difficulty in platform layer processing caused by inconsistent protocol outputs of various types of sensors; it solves the problem of misjudgment of warnings caused by the lack of unified warning specifications for sensors; and it improves the ability of the platform layer to conduct unified analysis and deep mining of data.

[0085] The threshold judgment module is used to determine the power transmission warning information of the power transmission monitoring data, the substation warning information of the substation monitoring data and the cable warning information of the cable monitoring data by means of threshold judgment.

[0086] The data appending module is used to append the power transmission warning information to the power transmission specification data to generate power transmission data, append the substation warning information to the substation specification data to generate substation transmission data, and append the cable warning information to the cable specification data to generate cable transmission data.
