Abstract

The invention discloses a wireless remote meter reading method, a system and a device thereof. The method provided by the embodiment of the invention comprises that the reported electric meter data is received and then converted into signals transmitted in a 3G network; PS domain is adopted as a passage for transmitting the signals and the signals are transmitted to a major station by the 3G network. The embodiment of the invention also discloses a wireless remote meter reading device which comprises a receiving module for receiving the reported electric meter data, a conversion module for converting the received electric meter data by the receiving module into the signals transmitted in the 3G network, a transmission module which transmits the signals in the PS domain by the 3G network to the major station. The method of the embodiment of the invention has good network guarantee, low operation cost and comparatively high data transmission speed but no distance and space limit.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, system and device for wireless remote meter reading. Background technique [0002] At present, there are many technologies for meter reading in China, such as manual meter reading, RS485, infrared and power line carrier. Among them, RS485 and infrared meter reading technologies are relatively mature and widely used, while power line carrier meter reading can only be used in a small area. RS485 meter reading requires wiring and can only be implemented in a small area (less than 1000 meters); infrared meter reading requires manual on-site meter reading; due to the influence of technology and the objective conditions of the domestic power grid, there are still many technical problems in power line carrier meter reading; [0003] The GPRS power remote meter reading system consists of the power distribution center located in the power bureau and the meter data collec...
