System Design of Serial Port Communication between 51 Single-chip Microcomputer and PC

摘要：

The serial asynchronous communication is an efficiency data transfer method. In this paper downward machines use the MCS89C52 single chip microcomputer as the core unit device to design a data acquisition from the Electronic Balance DT20K. The upward machines software which adopt the multithread technique and the serial communication mechanism technique can control the data acquisition device effectively, provide a multiform observation about the data, overlook or see it in detail, and store the data automatically in database. The system makes the data acquisition and the system control more convenient and efficiency. The system works steady and has a good real time performance, so it can be applied widely.
