How does the electronic remote water meter LoRa transmit data remotely?
With the gradual development of my country's water supply measurement business, the types of water supply measurement instruments are also constantly enriched. Electronic remote water meters are one of the mainstream products in the water meter industry today. Because there are many types of electronic remote water meters, here we take LoRa as an example. , to explain to you how the table realizes data remote transmission.
Electronic remote water meter LoRa realizes data remote transmission mainly followed by two layers of communication. The downlink communication mainly uploads the water meter data to the concentrator, and the uplink communication mainly uploads the data from the concentrator to the server.
Downlink communication: It is a wireless communication method between the wireless remote meter and the concentrator, using a frequency range of 470-510Mhz (other frequencies can also be customized), and the transmission power is less than or equal to 50mW to communicate data wirelessly. The system can form up to 4-level routing transmission modes according to the actual network relationship to adapt to the ever-changing actual needs of users.
Uplink communication: It is the data communication between the concentrator and the main station. The data concentrator adopts a unified uplink communication protocol and adopts a modular design. It can use a variety of data transmission methods with the main station data acquisition server, and can flexibly use Ethernet according to the user's actual situation. network or GPRS/3G/4G access network.
The above is our introduction to the remote transmission method of electronic remote water meter LoRa data. If you need more information, please feel free to contact us.
