This product is a brand new wired-to-wireless wireless acquisition terminal developed by our company for users. This product is connected to the electronic sampling module of each meter through signal lines such as RS485 and TTL. It is designed with LoRa wireless spread spectrum modulation technology. , Effectively guarantee the problem of ultra-long distance transmission of small data volumes in complex environments. The collection terminal has the function of reporting regularly every 6 hours to ensure the real-time nature of the user's meter data in daily life. A multi-user LoRa acquisition terminal can carry up to 16 meters, wireless transmission distance can reach more than 3km, built-in high-capacity lithium battery, no need to match external power supply, solving wiring problems and low construction costs.
Wake up wirelessly
The collection terminal can wake up remotely and wirelessly, and respond to the processing instructions of the upper computer in real time.
Single copy function
The acquisition terminal can be compatible with pulse, photoelectric, Hall and other sampling methods to achieve high-precision measurement.
The acquisition terminal is always in a sleep state, and the module can upload a real-time data by triggering a reserved reed switch once.
Automatic table lookup
The acquisition terminal can automatically find the table by command, and save the address of the found table.
Add table address
The collection terminal can increase the table address by command.
Delete table address
The collection terminal can delete the table address by command.
Quick meter reading (only applicable to multi-user wireless handsets)
The handset first issues a command to start a fast meter reading. The multi-user acquisition terminal that receives the command first reads the data at the meter reading end. After completing the internal storage, wait for the upstream meter reading command. It will automatically exit the quick meter reading command; if the reading of the connected meter is completed, it will exit automatically.
