Problems solved by technology
There are two defects in the communication method adopted by the existing CMA: First, when natural disasters such as earthquakes and floods occur, resulting in a power outage of the public network base station or a synchronization failure of the microwave directional antenna, the CMA will lose communication with the main station, and the main station cannot Normal monitoring of the status information of the transmission line; second, the existing CMA only has the function of data format conversion and forwarding, and the fault discrimination function is at the master station
This communication method has higher requirements on channel bandwidth and quality, and will generate higher public network fees

The invention discloses a power transmission line on-line monitoring device and monitoring method. The power transmission line on-line monitoring device is connected with a plurality of state monitoring devices. The power transmission line on-line monitoring method comprises the following steps that a control module obtains detection data of state monitoring equipment, carries out edge calculation processing on the detection data, and transmits a processing result of the detection data to a remote master station in a wired or wireless manner. By acquiring the detection data of the plurality of sets of state detection equipment and carrying out edge calculation processing on the detection data, the detection information of the equipment in the fault state or the alarm state is uploaded to the remote master station, so that the data transmission quantity and the requirement on the communication bandwidth are reduced, and the communication cost and the operation and maintenance cost are reduced.
Description
technical field [0001] The invention relates to the technical field of power equipment monitoring, in particular to an on-line monitoring device and method for power transmission lines. Background technique [0002] The transmission line online monitoring system uses sensors to collect and analyze graphics, images, videos and industrial measurement data (tower tilt, micro weather, insulators, infrared temperature measurement, external force damage prevention, etc.) and automatic alarm, system network topology such as figure 1 shown. The condition monitoring device (CMD) of the local tower collects data and transmits it to the condition monitoring agent (CMA) of the local tower through the local data collection network (local datacollocation network, LDCN). The CMA of each tower passes the data The remote communication network (data remote transmission network, DRTN) transmits the monitoring data to the monitoring master station. The communication model of the monitoring s...
