The advent of LoRa wireless remote transmission smart water meters has effectively alleviated the troubles and secondary economic losses caused to the water department and users by the traditional meter reading charges. Gradually adapted to the current demand for more and more high-end commercial and residential applications. Realized a leap from the original installation of water meters indoors or underground to outdoor metering of energy consumption meters!
(1)The basic composition of LoRa wireless remote intelligent water meter: It is composed of wireless communication module and base meter. A dry or wet water meter is used as the measurement base meter, and a tap water measuring device with remote transmission and output measurement data is installed. Receive the meter reading instruction of the wireless meter reading master device to transmit data. With measurement, calculation, storage, diagnosis, wireless remote transmission and other functions.
The measuring method of LoRa wireless remote transmission intelligent water meter adopts double reed pipe detection method. Effectively avoid errors caused by electromagnetic interference and pulse jitter.
(2) Communication method of LoRa wireless remote intelligent water meter: its communication module is usually in sleep state. Wake up every second for a short period of time during which to listen for wireless instructions. If so, start the receiving function to receive data; if not, continue to enter the sleep state. This method greatly reduces the average power consumption of the module and effectively extends the battery life. The water company only needs to install the wireless remote transmission smart water meter like an ordinary meter. Meter readers only need to operate the background software in the office to capture water meter data and remote control valves throughout the city, and the remote meter reading system automatically reads the meter once a day. Real-time grasp of the current data and historical data of each household's water meters, the residential water meter concentrated area is most suitable for this remote meter reading method.
The emergence of LoRa wireless remote transmission intelligent water meters will undoubtedly bring us closer to the beautiful era of "smart cities" and allow "technology to change our lives".
