The invention relates to a remote communication type electric measurement apparatus and a communication board thereof. The communication board of the remote communication type electric measurement apparatus is designed on a circuit board inside the communication type electric measurement apparatus. The communication board is connected with an MCU chip on the circuit board through a serial port and is controlled by the MCU chip on the circuit board; the communication board acquires a working power source through a power source chip on the circuit board; the communication board is provided with a card slot used for accommodating and reading a nano-SIM type communication card and a reading circuit coupled to the card slot.
Description
technical field [0001] The present invention relates to smart grid technology, more specifically, the present invention relates to a communication board for remote communication electrical measurement equipment (for example, in the form of GPRS / 3G communication protocol), which is used to improve the manufacturing structure and installation method of electrical measurement equipment , which in a preferred example further relates to a remote-readable electricity measuring device, such as a prepaid electricity meter. Background technique [0002] With the continuous updating of scientific and technological means, the performance and manufacturing process of electrical measuring equipment have also improved, and in order to pursue higher performance and greater expansion space, the circuit board design of the equipment requires smaller size and larger installation space. While increasing the functionality and speed of operation of these parts in most cases, a major factor in t...
