ajst-2168	Chen, Jilong; Chen, Yuling	Design and Implementation of Single-phase Electrical Analyzer	2022	2	.pdf	application/pdf	1331	64	55	2. System Scheme Design This system is mainly composed of single chip microcomputer control module, measurement module, display module, communication module, power module, the following respectively demonstrate the selection of these modules. 2.1. Comparison and selection of main control chip schemes Scheme 1: using STC89C51 single chip microcomputer STC89C51 is a kind of microcontroller, has the characteristics of low power consumption, high performance, with system programmable (ISP) characteristics, and then with PC control program can download the user's program code to the MCU internal, and the speed is fast, but STC89C51 has only one serial port, does not meet the requirements of sending and receiving two serial ports.	cache/ajst-2168.pdf	txt/ajst-2168.txt
