摘　　要：为满足数显转矩扳手通信接口体积小、功耗低的要求,设计一种基于CH341T芯片的USB串口通信电路。在VB环境下开发上位机软件,以STC12LE5410AD单片机为下位机对转矩进行测量,实现了数显转矩扳手与PC机的数据传输。实验结果表明,该通信接口电路结构简单、可靠好,尤其适合于便携式设备。In order to solve the problem that the communication interface of digital torque wrench required small volume and low power consumption, a USB serial communication circuit based on CH341T was designed. The principal computer software was developed in VB environment with STCI2LE5410AD SCM as slave computer to measure the torque, and the data transmission between digital torque wrench and PC computer was realized. Experiments showed that the communication interface circuit was simple and reliable, it was especially suitable for portable devices.
