Wireless valve control remote water meter

Wireless valve control remote water meter
Overview
 
The valve control function is added on the basis of the wireless remote water meter, which solves the problems of users maliciously defaulting on the water meter and charging difficulties, and realizes the remote real-time monitoring and remote valve switching and prepayment functions. The wireless module uses LoRa modulation technology to send and receive data wirelessly. It is a wireless remote transmission module with small size, low power consumption, strong performance and long transmission distance. The module's radio frequency chip is based on spread spectrum technology and has the characteristics of anti-interference and high reliability; it greatly surpasses the existing GFSK modulation module in terms of stability, anti-interference ability and receiving sensitivity.

characteristic
1. Using intermittent pulse and photoelectric sensor.
2. WOR electromagnetic wave wake-up technology, instantly wake up the water meter to make it in the communication state, and automatically restore the low power consumption state after the meter reading is completed.
3. Reasonable TDMA backoff algorithm to reduce the chance of data collision.
4. Adopt the latest nano-coating technology, no leakage electrode, good sealing performance, to ensure stable operation of the circuit board in a humid environment
5. The control function, with its own valve, can be switched on and off as needed to prevent malicious default of water charges.
6. Integrate with the host computer system to establish a remote automatic meter reading management system to truly realize meter reading and monitoring automation.
7. Charges support third-party WeChat, Alipay, and bank card payment.
8. The function of step water price can be realized.
