Product ApplicationIntelligent wireless remote centralized meter reading has experienced many years of development. With the continuous improvement of core technology, it has got rid of the early doubts about the stability and reliability of the scheme. It has gradually established a good market acceptance in practical application at home and abroad. At the same time, facing various complex situations such as power consumption and construction problems, the wireless centralized meter reading scheme is better and more convenient. The countermeasures will gradually become the mainstream scheme in the future. Based on years of practical experience and advanced technology exploration, according to the requirements of power consumption, transmission distance and anti-interference of wireless meter reading, the most advanced LoRa spread spectrum modulation wireless transmission technology is adopted. At the same time, combined with years of application experience in water meter industry, a safe and reliable wireless communication is designed. The transmission protocol of meter reading has formed an intelligent LoRa wireless remote water meter system with high reliability, convenient system expansion, simple installation and maintenance, and high success rate of meter reading.

Main Features1.The system adopts the time division multiple access (TDMA) communication mode, and automatically synchronizes the communication time unit. Frequency hopping technology avoids co-frequency interference and improves the reliability of transmission. The adaptive algorithm of transmission rate and transmission distance effectively improves the system capacity.
2. Wireless remote water meter system integrates collection and measurement, bidirectional communication and meter reading control valve. The system includes wireless remote water meter, concentrator and meter reading system.
3. The system is suitable for remote meter reading and control of multi-storey, high-rise slab, tower, villa, apartment and other building structures.
4. The system is based on LoRa communication technology and adopts star network structure. The communication delay is small and the transmission distance is long and reliable.
5. Neighbouring cells can share concentrators, expand wireless transmission distance without using repeaters, reduce system costs and improve the success rate of meter reading. The concentrator can manage up to 5000 water meters.
6. Water meter has three working modes: LOP1, LOP2, LOP3, response time: 12s, 24h-12s, 24h; ER18505 battery life: more than 6 years, customers can switch any working mode by concentrator in the actual use process; automatic maintenance of valves every month.
7.Without complicated construction wiring and small amount of work, the concentrator and water meter form a star network, which is composed of GPRS and back-end server. The network structure is stable and reliable. At the same time, all water meters and concentrators adopt independent core technologies such as multi-frequency, multi-rate, anti-interference, etc. to avoid the problems of not being able to read meters and instability of reading meters, so as to make the system run stably for a long time and reduce the maintenance cost greatly in the later period.
8. Including metering, anti-magnetic attack, power supply voltage detection, metering value power-off storage function, valve in place switch status detection, control valve circuit, automatic dredging valve.
9. The concentrator stores 5000 pipelining data and 10-12-month frozen data.
10. Active reporting data mode: 24-hour active reporting of meter reading data.
