Intelligent electricity consumption information acquisition terminal is a device that collects electricity consumption information at each information collection point to achieve data management, two-way transmission of data, and forwarding or execution of control commands, referred to as the acquisition terminal. Electrical information acquisition terminals are classified according to application sites. It can be divided into special transformer acquisition terminal, centralized meter reading terminal, distributed energy monitoring terminal and other types. (1) special transformer collection terminal. The special transformer acquisition terminal is a device that collects the electricity information of the special transformer user, which can collect the energy meter data, monitor the working condition of the energy metering equipment and the power quality of the power supply, and monitor the customer's electricity load and energy, and manage and transmit the collected data bidirectional. (2) concentrated meter reading terminal. The centralized meter reading terminal is a device that collects the electricity information of low-voltage users, including a concentrator and a collector. The concentrator refers to the device that collects the data of each collector or energy meter, processes and stores it, and can exchange data with the main station or handheld device. The collector is a device used to collect energy information of multiple or single energy meters and exchange data with the concentrator. (3) the distributed energy monitoring terminal. The distributed energy monitoring terminal is a device that monitors and controls the user-side distributed energy system connected to the public power grid, which can collect information and monitor power quality of two-way energy metering equipment, and can accept the command of the master station to control the distributed energy system's access to the public power grid.
electric energy data acquisition terminal (Electric energy Data Acquisition terminal) is a device for the acquisition of electricity information at each information collection point, referred to as the acquisition terminal. The device can realize the collection, data management, two-way transmission of data, and forwarding or execution of control commands of the energy meter. Electricity information acquisition terminals are divided into specialized acquisition terminals, centralized meter reading terminals (including concentrators, collectors), distributed energy monitoring terminals and other types according to the application site.
