Embodiment Construction
[0030] The following will describe in detail a fault indicator collision prevention method and fault indicator based on networking communication provided by the present invention with reference to the accompanying drawings. This embodiment is implemented on the premise of the technical solution of the present invention, and the detailed However, the scope of protection of the present invention is not limited to the following examples, and those skilled in the art can modify and modify them within the scope of not changing the spirit and content of the present invention.
[0031] The invention provides an anti-collision method and a fault indicator for a fault indicator based on networking communication. The concentrator selects an idle frequency point as a solidified frequency point and performs a frequency point conflict self-check after the solidified frequency point, so as to avoid multiple sets of equipment. When running at the same time, the channel collision of radio freq...

The invention discloses a fault indicator anti-collision method and a fault indicator based on networking communication. When multiple sets of fault indicators are networked, the concentrators of different fault indicators perform networking communication. The collector and the corresponding concentrator carry out networking communication, wherein, when the concentrator performs networking communication, the working frequency is determined by the following steps: searching for the frequency to be used; broadcasting the networking data packet; according to the response situation, determine Whether the frequency to be used is free, until the working frequency is found or all the frequencies in the preset frequency list are searched. The invention can avoid the collision of radio frequency channels, ensure the reliable operation of multiple sets of fault indicators, and greatly improve the efficiency of full inspection and production debugging of the fault indicators.
Description
technical field [0001] The invention relates to the field of electric power, in particular to a fault indicator anti-collision method and a fault indicator based on networking communication. Background technique [0002] For a long time, the operation monitoring method of the distribution network is relatively simple, mainly using FTU or DTU line monitoring equipment, which can monitor the operation of the distribution network, but the cost is high, and it is not suitable for large-scale installation and use, especially in remote mountainous areas, such as in C Class, D, E power supply area. It is also necessary to install line monitoring equipment in these power supply areas to improve the operation and management standards of the distribution network. Therefore, the use of line monitoring fault indicators has become the current trend to solve this problem, which can effectively improve the operation reliability of the distribution network. [0003] The fault indicator is ...
