What is a smart area user identifier?

The low-voltage transformer load station user identification instrument (hereinafter referred to as "intelligent station user identification instrument") produced by our company is a patented product developed based on zero-crossing power line communication technology. This product consists of a transmitter host and a handheld terminal. Users use transmitters to send phase information and equipment number information to the distribution network at the low voltage side of the substation, and hand-held terminals can accurately receive phase information and equipment number information within the power supply radius of the substation.

This product is a new generation of high-reliability identification tool, which fully meets the needs of user identification and differentiated attribute identification in the station area. This product is based on the patented technology of power frequency zero-crossing communication, with strong anti-interference ability, strong point-to-point communication ability and long communication distance.

This product is mainly used in distribution network survey, distribution network contracting, power consumption inspection, production scheduling, operation and maintenance and other fields.

The functional features of this product are:

1. The instrument adopts aluminum alloy portable integrated box design, which has good mechanical properties and corrosion resistance. The whole machine is light in weight, and the terminal can be placed in the main box, which is very suitable for carrying and using in the field.

2. Both the terminal and the host adopt large-screen dot-matrix liquid crystal display, both of which are displayed in simplified Chinese, with intuitive operation and background light, which is convenient for use in dark places.

3. The configuration of the terminal and the host is flexible, there is no binding relationship, and there is no need to reset when configuring. Through the keyboard, the host number can be changed flexibly, and the user identification of power supply areas of multiple distribution transformers under complex conditions can be realized.

4. The host has real power protection function. When the 220V power supply is connected to 380V by mistake, the instrument will automatically cut off the circuit quickly to protect the safety of the instrument and operators.

5. The terminal has countdown prompt function and voice prompt when waiting (after receiving the signal), which is very convenient for users to use.

6. Compared with the products based on FSK carrier communication technology, this product has the characteristics of high signal-to-noise ratio, strong signal and accurate information identification. Compared with similar products, it has the characteristics of fast identification speed, no * * * high voltage crosstalk, * * * cable trench crosstalk and * * * zero line crosstalk, intuitive display and simple operation.
