Problems solved by technology

[0003] In many complex and diverse landforms, mountains, plateaus, plains, valleys, deserts, and Gobi are surrounded by mountains and mountains. Mountains, deserts, and Gobi areas are affected by the signal coverage of the three major telecom operators, and some power grid power lines communicate within the area. The signal is poor, so that the distribution network equipment installed on the line cannot communicate with the master station
[0004] At present, there are many applications of wireless ad hoc networks in power systems, but most of them are focused on image transmission, individual inspections, etc., with high costs and high power consumption, making it difficult to locate faults in distribution networks that are widely distributed and difficult to obtain energy. Promote the application in the system

Abstract

The invention discloses a power distribution network micro-power consumption wireless information transmission device, which comprises a mainboard, a communication circuit board and an antenna, and is characterized in that the mainboard is in a wake-up state every T time, releases self wake-up information after each wake-up, and enters a dormant state immediately when no data needing to be transmitted is received within delta time after the wake-up information is sent; when holding data needing to be transmitted, the mainboard is in an awakening state for T + delta time, and when other awakening equipment is found in the period, the held data is transmitted to the equipment; a power supply, a main controller, a memory and a communication interface are loaded on the main board; the RS485 interface, the RS422/RS232 interface and the optical fiber interface are respectively connected with the main controller, and the memory is connected with the main controller; a radio frequency circuit and a radio frequency transceiver module are loaded on the communication circuit board. The device can solve the offline problem of distribution network automation equipment caused by communication problems, has the characteristics of low cost, easiness in installation, flexibility and the like, and has remarkable advantages compared with the traditional communication technology.

Description

technical field [0001] The invention relates to the technical field of signal transmission devices, in particular to a micro-power consumption wireless information transmission device of a power distribution network. Background technique [0002] The 10kV distribution network fault automatic location system is the main means of online detection of the current distribution network. Through the application of the 10kV distribution network fault automatic location system, the online detection and perception of the 10kV distribution network is well solved. The abnormal situation of the power grid is sensed, and the fault handling of the distribution network is upgraded from passive to active, realizing a qualitative change and solving the problem of rapid response service to the current society's demand for high-quality power. [0003] In many complex and diverse landforms, mountains, plateaus, plains, river valleys, deserts, and Gobi are surrounded by mountains and mountains. T...
