1Remote intelligent meter reading systemoverview

The measuring instruments of major water users in the water supply company are mostly installed in underground meter wells. Under the traditional meter reading method, the meter reader needs to carry a meter reading book with them and open the manhole cover, or even go down to the bottom of the well to read the meter. After completing all the meter reading work in the area, they will transfer the data to the toll collector and input it into the computer. This meter reading method not only has a long cycle and low efficiency, but also the accuracy of meter reading data is difficult to guarantee.

The mobile wireless meter reading system fully integrates 433MHz, Bluetooth wireless communication technology, and microcomputer information processing technology, allowing meter readers to read meters wirelessly with one click through the mobile APP without opening the manhole cover after arriving on site, avoiding the estimation, omission, and error of manual meter reading, and ensuring the accuracy of meter reading data.

2. Composition of Remote Intelligent Meter Reading System

The mobile wireless meter reading system mainly consists of four parts: meter reading management machine, mobile APP+433MHz/Bluetooth conversion module, 433M low-power measurement and control terminal, and measuring instrument.
Meter reading management machine: Install meter reading management system software to store, query, analyze, and process meter reading data.
◆ Mobile APP+433MHz/Bluetooth conversion module: One click access to multiple user meter data, and export it to the meter reading management machine via USB/WiFi.
433M low-power measurement and control terminal: automatically collects flow meter data inside the meter well and transmits it to the outside of the meter well through 433MHz RF signal.
Measurement instruments: electromagnetic flowmeter, ultrasonic flowmeter, pulse water meter, etc.

4. Characteristics and functions of remote intelligent meter reading system

◆ Avoid errors, omissions, and misunderstandings in meter reading, and ensure the accuracy of meter reading data.
Wireless meter reading without opening the manhole cover ensures the safety of meter readers and avoids accidents.
◆ Save manpower, greatly improve meter reading efficiency, and reduce the processes of copying, reviewing, and inputting.
Shorten the meter reading cycle and avoid the phenomenon of "bi monthly meter reading" and "multi monthly meter reading" caused by heavy workload.
The 433M low-power measurement and control terminal has extremely low power consumption and comes with 2 lithium batteries that can sustain operation for more than 2 years.
