1. General Descriptions



Model DIN-BOX-168 box (hereafter referred as Tbox) is a multifunction metering solution composed of Meter Box, Measurement & Control Unit (MCU), Data Concentrator (DC) and User Interface Unit (UIU). Each Tbox can access the farend servers via GPRS, so that the administrators can remotely operate Tboxes and read all the meters' energy consumption information. It can help utility companies to largely improve the management efficiency of their power grids, and reduce the management cost. For users, UIUs installed in their homes could achieve energy consumption data from box via RS485 communication, and display to users, so that it is not only convenient for them to read data, but also avoid disruption of energy measurement. Thus, this is a complete metering box solution which combines measurement, use and management of energy.

The box is composed of PC (polycarbonate) cover and ABS base, with performance of reliable insulation, high strength, good flaming resistance, anticorrosion, antiaging and lifetime of over 10 years. It could be widely used in housing construction or civil power grids transformation, with features of multiple combinations of different metering units, easy installation, hidden cable connection and safe operation.

2.3. Operation Principles

A single set of meter box is made of 1 Box, 12 MCUs, 1 DC and 12 UIUs. The box supplies power to the MCUs, DC and UIUs. The MCUs are used for energy measurement, the UIUs for display of energy and electrical parameters, while the DC for reading & transmitting data from MCUs and communicating with the Server. Communication between MCUs and DC is by RS485, between UIUs and DC is by RS485, while between DC and Master Station System is by GPRS.





When the administrators need to read the meter data, below steps should be taken:

1) The administrators send data reading command from the browser interface;

2) The Server will receive the command and send to the DC via GPRS communication;

3) The DC transmits the command to the MCUs and collects the data;

4) The DC sends the data to the browser interface;

5) The data will be saved in the database during this process.





Users can input some codes on the UIUs' keyboards to check and view their energy consumption data. The displayed data are stored in the UIUs, and the DC will keep sending and upgrading the latest energy consumption data to the UIUs.
