[0033] See also Figure 1 An embodiment of the present invention provides an electric power Internet of Things control system, which includes: a plurality of sensing units 100, which are configured at an electric power site and connected to electric power equipment (not shown) at the electric power site, wherein a wireless connection relationship is established between the plurality of sensing units 100, and the sensing units 100 are used to obtain environmental sensing data of the corresponding electric power site and obtain electrical monitoring data of the corresponding electric power equipment; at least one convergence unit 200, each convergence unit 200 is electrically connected to at least one sensing unit 100, and is used to receive and forward the environmental sensing data and the electrical monitoring data; an access unit 300, and the access unit 300 is electrically connected to the convergence unit 200, and is used to receive the environmental sensing data and the electrical monitoring data, and send the environmental sensing data and the electrical monitoring data to a power main control center 400.

[0034] In one possible implementation, a power Internet of Things control system based on a mesh structure is adopted, by configuring a sensing unit 100 for each power device, and using the sensing unit 100 to sense the environment near the power device and obtain corresponding environmental sensing data, as well as to sense the operating status of the power device and obtain corresponding electrical monitoring data. After obtaining the above data, the above data is uploaded to the corresponding aggregation unit 200 by wireless transmission.

[0035] See for example Figure 2In an embodiment of the utility model, the perception unit 100 includes a data sensing module 110, a first wireless communication module 120, and a channel listening module 130: the data sensing module 110 is used to obtain environmental perception data of the power site and electrical monitoring data of the corresponding power equipment; the channel listening module 130 is used to listen to the communication channel of the convergence unit 200 and generate channel listening information; the first wireless communication module 120 is electrically connected to the adjacent perception unit 100 or the corresponding convergence unit 200, and is used to perform corresponding data sending operations according to the channel listening information.

[0036] See also Figure 3 In an embodiment of the utility model, the data sensing module 110 includes a first sensing module 111 and a second sensing module 112. The first sensing module 111 is used to obtain environmental perception data of the power site, and the second sensing module 112 is used to obtain electrical monitoring data of the corresponding power equipment.

[0037] Preferably, the first sensing module 111 includes a temperature sensor, a humidity sensor, an air pressure sensor, and a wind sensor; the second sensing module 112 includes a current sensor and a voltage sensor.

[0038] In the specific implementation process, the perception unit 100 includes a data sensing module 110 composed of a first sensing module 111 and a second sensing module 112. Through the data sensing module 110, the environment of the power equipment configured on site can be perceived and corresponding environmental perception data can be obtained. For example, the environmental perception data includes but is not limited to temperature data, humidity data, air pressure data, wind direction data, and wind force data, etc., as well as the operating status of the power equipment can be perceived and corresponding electrical monitoring data can be obtained. For example, the electrical monitoring data includes but is not limited to voltage data, current data, etc.

[0039] After acquiring the above data, the data sending operation is not performed immediately on the above data. Instead, the communication channel of the aggregation unit 200 is listened to through the channel listening module 130 in the perception unit 100, and corresponding channel listening information is generated. For example, the channel listening information is that the channel is busy or the channel is idle. The first wireless communication module 120 sends the above sensed data based on the above channel listening information. For example, when the channel listening information is that the channel is idle, the first wireless communication module 120 sends the above sensed data, specifically, to the adjacent perception unit 100 or the corresponding aggregation unit 200.

[0040] In one possible implementation, the first wireless communication module 120 in the perception unit 100 is composed of a first wireless communication submodule 121 based on long-range wireless communication (for example, a 4G or 5G communication module) and a second wireless communication submodule 122 based on short-range wireless communication (for example, a Bluetooth, WIFI, Zigebee module). In the actual data transmission process, wireless communication with the aggregation unit 200 is preferentially performed through the first wireless communication submodule 121 to send the sensed data to the aggregation unit 200. In another embodiment, the first wireless communication submodule 121 cannot perform reliable wireless communication with the corresponding aggregation unit 200, so the perception unit 100 automatically communicates wirelessly with the adjacent perception unit 100 through the second wireless communication submodule 122, and sends the sensed data to the aggregation unit 200 or further to other adjacent perception units 100 through the adjacent perception unit 100 to achieve reliable transmission of the sensed data.

[0041] See also Figure 4 In an embodiment of the utility model, the convergence unit 200 includes a second wireless communication module 210, a data merging module 220, a data caching module 230, an I / O module 240 and a debugging module 250. The second wireless communication module 210 is electrically connected to the first wireless communication module 120, and is used to receive the environmental perception data and the electrical monitoring data from the first wireless communication module 120; the data merging module 220 is connected to the second wireless communication module 210, and is used to perform a data merging operation on the received environmental perception data and the electrical monitoring data to generate merged environmental perception data and electrical monitoring data; the data caching module 230 is connected to the data merging module 220, and is used to perform a data caching operation on the merged environmental perception data and electrical monitoring data; the second wireless communication module 210 is also used to forward the merged environmental perception data and electrical monitoring data to the access unit 300.

[0042] Preferably, the access unit is any one of an RTU (Remote Terminal Unit), a DTU (Distribution Terminal Unit), an FTU (Feeder Terminal Unit) and a TTU (Transformer Terminal Unit).

[0043] In a possible implementation, the aggregation unit 200 receives the above-mentioned environmental perception data and electrical monitoring data from the connected multiple perception units 100. Specifically, the second wireless communication module 210 communicates wirelessly with the first wireless communication module 120 to receive the above-mentioned environmental perception data and electrical monitoring data. Since the upload time and upload quantity of the above-mentioned data are uncertain, in order to improve the data transmission efficiency, after receiving the above-mentioned data, the above-mentioned data is further merged by the data merging module 220. For example, all environmental perception data and electrical monitoring data received within a period of time are packaged into merged environmental perception data and electrical monitoring data, and then cached in the data cache module 230. At this time, the second wireless communication module 210 forwards the cached merged environmental perception data and electrical monitoring data to the access unit 300 at one time to improve the data transmission efficiency.

[0044] The optional implementation modes of the embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the embodiments of the present invention are not limited to the specific details in the above implementation modes. Within the technical concept of the embodiments of the present invention, various simple modifications can be made to the technical scheme of the embodiments of the present invention, and these simple modifications all belong to the protection scope of the embodiments of the present invention.

[0045] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the embodiments of the present invention will not further describe various possible combinations.

[0046] In addition, various implementation modes of the embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the embodiments of the present invention, they should also be regarded as the contents disclosed by the embodiments of the present invention.
