基于STM32的智能WiFi万用表设计

Design of intelligent WiFi multimeter based on STM32

针对传统万用表自动化水平低、操作不便等问题,该文设计了一款智能WiFi万用表,不仅具有普通万用表测量电阻、电压、电流的功能,而且还具有自动切换量程、记忆存储、远程监控等功能。文中详细阐述了系统各个模块的硬件电路,给出了软件系统流程图,并对实物进行了测试。与传统数字万用表相比,提高了测试效率。该表使用方便、体积小、造价低,具有广泛的应用前景。

In view of problem of the traditional multimeter low automation,inconvenient operation,this paper designed a intelligent WiFi multimeter. It not only has ordinary multimeter＇s function to measure the resistance,voltage,current,but also has the automatic switching range,memory storage,remote monitoring function. This paper expounds the system each module of hardware circuit,then present the flowchart of software system,and a test was carried on. Compared with the traditional digital multimeter,the intelligent WiFi multimeter improve the testing efficiency,convent to measurement and observation. It is convenient to use,and has small volume and low cost,so it has wide application prospect.
