The near-field intelligent meter reading system based on Bluetooth — Broadband carrier

At present, there are many problems in infrared technology of the near-field smart meter reading, such as being easily interfered by light, low transmission rate, long meter reading time, short operating distance and so on. To above issues, this paper presents a technical scheme of field meter reading based on Bluetooth technology and broadband carrier instead of infrared technology, and designs an improved algorithm for communication scheduling based on message queue process, and proposes a protocol layer improvement scheme for 645 protocol (Multifunctional energy meter communication protocol) forwarding object-oriented communication protocol. Then this article designs a simple mobile phone APP (Application) for near-field communication test. Finally, the program has been demonstrated, tested, and simulated, and the ideal effect is achieved. It plays a certain role in improving the environment of near-field meter reading.
