Introduction To the Main Transmission Methods of Electronic Remote Water Meters
To solve the problem that traditional mechanical water meter information islands cannot realize large-scale meter reading, many water companies have begun to try to use electronic remote water meters with data remote transmission function. The remote meter reading system mainly introduces the data of electronic remote water meters. transfer method.
At present, there are two main transmission methods for electronic remote water meters. One is a wireless remote transmission scheme based on a wireless remote water meter, and the other is a wired remote transmission scheme based on a wired remote water meter.
We usually know that the bus meter reading method is to transmit various data on a bus. The bus system has the advantages of simple lines, easy wiring, easy construction, low cost, strong anti-interference, and strong reliability. The available bus control systems are centralized meter reading system and centralized meter reading valve control system. Different schemes can be selected according to actual needs to completely realize the goals of remote meter reading, remote diagnosis, remote control, stepped water price, and prepayment.
The wireless remote control water meter is a real-time online data transmission through the wireless communication module, with a remote control operation system. Each water meter is equipped with a wireless signal receiving and sending unit control, and the water data is transmitted through the wireless signal and the terminal of the control concentrator. The wireless remote water meter can also realize functions such as remote meter reading, alarm prompt, remote diagnosis, remote monitoring, stepped water price, prepayment, etc. Its advantages are that no wiring is required, and the construction is simple. The disadvantages are the cost is high, and the wireless signal transmission distance will be affected by the surrounding buildings.
