LCD wireless meter reading module WE1

system introduction

System composition: HAC-WE low-power wireless meter reading module, HAC-nLS low-power micro base station, HAC-RHU-E handheld, and meter reading system.

· The HAC-WE low-power wireless meter reading module sends data every half an hour, and the meter reading system reads 48 times and 240 sets of data a day. The 3.6Ah capacity lithium battery has a service life of more than 10 years.

· HAC-nLS micro base station is powered by solar energy + lithium battery, no external power supply is required, installation and maintenance are simple, and one micro base station manages 200 meters.

· HAC-RHU-E handheld is used for supplementary meter reading, mobile meter reading, and on-site terminal parameter setting.

· The HAC-WE meter reading application platform can be deployed on the cloud platform, the application platform is rich in functions, and the big data can be used for leakage analysis.

Features

1) Report data every 2h.

2) Provide multi-channel, effectively improve system capacity.

3) Time division + frequency division communication mode, automatically synchronizing the communication time unit, which can completely avoid data collision.

4) It integrates functions such as acquisition, metering, valve control, wireless communication, soft clock, ultra-low power consumption, power management, and anti-magnetic attack.

　· Support single and double pulse measurement, also can choose direct reading measurement method, fixed measurement method before leaving the factory．

　· Power management function, detect the transmission status or control valve voltage and report．

　· Magnetic attack detection function, generate an alarm sign when a malicious magnetic attack is detected．

　· Support power-off storage function, after the module is powered off, there is no need to re-initialize the metering value．

　· Support valve control, the valve can be controlled by sending commands from micro base station, etc.

　· Support wireless remote parameter setting.

　· Support power-off closing valve, power-on valve opening function．

　· LCD display time, alarm information, measurement data．

5) Use the key trigger to trigger the data to be reported on the table side or the table side to automatically bubble up to report the data.

6) Standard spring antenna, flexible circuit board antenna or other metal antenna can also be customized according to user products.

7) Soldering Farad capacitors as standard.

8) By default, use 4 dry batteries, 6V power supply.
