Problems solved by technology

Most of the power meters used are single-type pointer meters or digital display meters. A single meter can only display one operating parameter or multiple operating parameters of a loop. When there are many feeder loops, it is necessary to install multiple meters. The quantity is large, and the project construction cost is high; the parameter setting or interface switching of the existing instruments need to be realized through the operation buttons, and the operation is not intuitive enough
Moreover, the existing instruments do not have monitoring and communication functions or only use communication lines to communicate, with single functions and low intelligence level

Embodiment

[0022] The power supply of the processing control module 4 provides 24V or 5V DC power supply for each module of the instrument. The voltage dividing circuit 8 and the current sensor 9 of the parameter acquisition module 5 convert the primary voltage of different circuits of the power transmission and distribution equipment and the secondary current signal of the current transformer 9 into appropriate signals, and input them to the electric energy metering chip 10 for A / D Conversion, the converted parameters are output to the SPI data bus according to the SPI timing for MCU processor A to read. At the same time, the switch state detected by the photoelectric isolation circuit 6 and the temperature information of the detection point collected by the temperature sensor 7 are transmitted to the MCU processor A in real time; the MCU processor A uploads the collected and processed signal to the MCU of the processing control module 4 for processing through the RS485 bus Device B. T...

Abstract

The invention relates to a power meter and discloses an intensive type touch screen intelligent power meter. The intensive type touch screen intelligent power meter has the measurement, display and communication functions of an existing meter, and also has the intensive display, wireless communication, remote monitor and other functions of a touch screen. According to the adopted technical scheme, the intensive type touch screen intelligent power meter comprises a machine case, a plurality of parameter collection modules are installed inside or outside the machine case, the parameter collection modules are connected to a processing control module through wires or RS485 communication lines, and the processing control module is connected to a touch screen display module and a communication module through wires. The power meter has the RS485 communication function and has the GSM communication function additionally, the temperature and switching state detection display function is additionally provided for the meter, the monitoring capacity of power transmission and distribution devices by users is increased, workloads of operators and maintainers are reduced, and intelligent standard of power transmission and distribution devices is improved.

Description

technical field [0001] The invention belongs to the technical field of instruments and meters, and relates to an electric power meter, in particular to an intensive touch-screen intelligent power meter. Background technique [0002] At present, in order to measure and display the operating parameters of power transmission and distribution equipment in the power system, power meters are installed on the power transmission and distribution equipment. Most of the power meters used are single pointer meters or digital display meters. A single meter can only display one operating parameter or multiple operating parameters of a loop. When there are many feeder circuits, multiple meters need to be installed. The quantity is large, and the project construction cost is high; the parameter setting or interface switching of the existing instruments need to be realized by operating buttons, and the operation is not intuitive enough. And the existing instrument has no monitoring and com...
