Lora wireless prepaid token water meter has long transmission distance, low power consumption, small size, high reliability, convenient system expansion, simple installation and maintenance, and high meter reading success rate. The DDS5558 wireless remote water meter uses a high-performance, low-power LoRa wireless module.
Lora wireless prepaid token water meter, the DDS5558 wireless remote water meter uses a high-performance, low-power LoRa wireless module. Its special LoRa debugging method can greatly increase the communication distance, and at the same time, it can cooperate with advanced and efficient networking algorithms to realize complex environments by relaying neighboring nodes to each other. Long distance communication. The module can implement up to 9 relays. The communication distance is 10 times more than that of the ordinary point-to-point mode. Lora Wireless Prepaid Token Water Meter has the characteristics of small size, low power consumption, and strong anti-interference ability.
Low-power wireless meter reading system integrates metering, two-way communication and meter reading control valves. Lora Wireless Prepaid Token Water Meter has long transmission distance, low power consumption, small size, high reliability, convenient system expansion, simple installation and maintenance, and high meter reading success rate. The TDMA time division multiple access communication method automatically synchronizes communication time units. Using frequency hopping technology to avoid the same frequency interference and improve the reliability of transmission. The use of transmission rate and transmission distance adaptive algorithm to effectively improve system capacity.
