Description

STM 32-based ammeter Technical Field The application relates to the technical field of power equipment, in particular to an electric meter based on STM 32. Background The intelligent ammeter is used as basic equipment for collecting electric energy data, plays a very critical role in the construction of a smart power grid, and an ammeter based on STM32 is a type of electric energy meter which utilizes an STM32 series Microcontroller (MCU) as a core control unit to realize functions of electric energy metering, data collection, processing, display, communication and the like, processes collected current and voltage data, calculates electric energy consumption (such as kilowatt hours) and displays the electric energy consumption through an LCD display screen. The utility model discloses a patent of publication number CN214669243U, its specifically disclose an ammeter cabinet convenient to change ammeter, be provided with ammeter mount pad in this ammeter cabinet, it includes the bottom plate, is provided with the boss on the bottom plate, and the upper end of boss is provided with the electrically conductive inserted pillar that is used for being connected with the ammeter for the installation and the change of ammeter are simple and convenient, and at the in-process of installation and change, need not to cut off user's power, can not bring inconvenience to user's life. In the above-mentioned patent, this ammeter is through setting up multiunit ammeter installation department for but quick assembly disassembly when the ammeter is installed, but owing to be provided with multiunit bolt hole on the mount pad, still need to fix a position the through-hole that corresponds on the ammeter with the bolt hole when the ammeter is installed and just can install, but owing to current circuit case inner space is less, make the use space of the mounting tool that uses always, such as screwdriver, spanner etc. compressed, the staff when the operation, the instrument very easily interferes with other parts in the circuit case, result in the instrument unable normal effort or the operation direction is restricted, further increased the degree of difficulty and the complexity of installation, so it is necessary to provide a can quick assembly and disassembly based on STM32 ammeter and solve above-mentioned problem. It should be noted that the above information disclosed in this background section is only for understanding the background of the inventive concept and, therefore, it may contain information that does not constitute prior art.
