Abstract

The invention relates to a direct current electric transmission line state detection communication system, which comprises a solar panel and a case, wherein the lower part of the solar panel is provided with a support frame, the support frame is fixedly arranged on a rod tower, the case is in a tube shape, two ends of the case are respectively provided with an upper end cover and a lower end cover, a Zigbee communication module and a GPRS (general packet radio service) communication module are respectively arranged above the upper end cover, a circuit board is arranged in the case, a MCU (micro controller unit) module, a RS232 communication module and a power supply module are respectively arranged on the circuit board, all modules are respectively connected through conducting wires, the power supply module is connected with the solar panel through a conducting wire, a connecting block is respectively arranged on the outer surface of two ends of the case, a fixing belt is arranged on each connecting bolt, and two ends of the fixing belt are connected through a connecting device. The system has the advantages that detection data of each state detecting device in each stage of rod tower can be received and integrated, and in addition, the sorted detection data can be filed and sent back to an information receiving center in a remote way; the solar energy is utilized for electricity supply, the environment is protected, and the cost can also be saved; and the system is firmly fixed on the rod tower, the fixing position can be freely regulated, the dismounting and the mounting are convenient, and the cost is low.

Description

technical field [0001] The invention relates to a state detection communication device for an overhead power transmission line, in particular to a state detection communication system for a direct current transmission line. Background technique [0002] DC high-voltage transmission technology is currently the most advanced long-distance transmission technology. Using DC transmission, the transmission capacity is large, the transmission distance is long, and the power and energy loss of power transmission is small. However, the construction cost of DC transmission lines is high, so in the actual operation process must be Ensure the safe operation of DC transmission lines. In order to achieve the purpose of safe operation of DC transmission lines, many state monitoring systems are often added to the lines, and reliable communication between systems is particularly important. However, in the existing direct current transmission line, the device for realizing communication bet...
