Design and Implementation of Wireless Gas Meter Reading System Based on Spread Spectrum Communication

Abstract

Aiming at the problem that the residential residentials structure is complicated and the building density leads to the difficulty of meter reading system of wireless gas meter reading system, the reliability of ad hoc network is high and the power consumption is high. A new scheme of Wireless meter reading system used low-power MCU STM8L052 and spread spectrum communication chip SX1278 are proposed. Gas meters, repeaters and data concentrators through the spread spectrum communication transmission of data and instructions, data concentrator and gas management system through the GPRS network for real-time communication. The practical application show that the reliability of the wireless ad hoc network gas meter is high and the reliability of the network is poor.
