The emergence of LoRa wireless remote transmission smart water meters has effectively reduced the trouble and secondary economic loss caused by traditional home meter reading to water utilities and users. LoRa water meters are gradually adapting to the growing demand for high-end commercial and residential applications. Water meters installed indoors or underground surpass outdoor energy consumption meters!
(1) LoRa wireless remote transmission intelligent water meter is composed of wireless communication module and basic water meter. It uses dry water meter or wet water meter as the measurement base water meter, and is equipped with tap water measurement device data with remote transmission output measurement function. Receive meter reading instructions from the wireless meter reading master device to transmit data, and have functions such as measurement, calculation, storage, diagnosis and wireless remote transmission.
The measuring method of LoRa wireless remote intelligent water meter is oboe detection method. This method effectively avoids errors caused by electromagnetic interference and pulse jitter.
(2) Communication method of LoRa wireless remote intelligent water meter: its communication module is usually in a sleep state, wakes up once every second for a short time, and listens to wireless instructions during this period. If so, activate the receive function to receive data. If not, continue to sleep. This method greatly reduces the average power consumption of the module and effectively extends the battery life. The water company only needs to install wireless remote transmission smart water meters like ordinary water meters. The meter reader only needs to run background software in the office to copy water meter data and remote control valves throughout the city, and the remote meter reading system automatically reads the meter reading every day. Once, grasp the current and historical data of the water meter for each household in real time. Districts with concentrated water meters are best suited for this remote meter reading method.
The emergence of LoRa wireless remote intelligent water meters will undoubtedly bring us closer to the beautiful era of "smart cities". Making "technology change our lives" is not only advertising, but also practical convenience and comfort in our lives!
