串口通信上位机界面，与下位机单片机通信，获取温度数据。-PC serial communication interface, and the next-bit single-chip machine communications, access to temperature data.

实现将单片机采集的温度值通过串口传输到上位机，此程序为上位机接收温度程序，将温度值描成曲线并显示，带有保存及打开历史记录功能。-To achieve the MCU collected temperature transferred to the host computer via serial port, this procedure for the host computer receives the temperature program, the temperature value Mi

污水厂读取上位机串口232的数据并保存在access数据库里，具体的数据可以根据上位机的变量来修改，可以做为学习用-Wastewater treatment plant to read the data of the host computer serial port 232 and stored in the database access to specific data can be modified based on the variables of the host computer,

包括串口通信的上位机程序。以及把上位机的数据存到access数据库和查询数据库内容的功能，同时还能把接收到的数据通过图形实时显示。-Including PC serial communication program. And the data stored in the host computer to access the database and query the contents of a database function, while the received data is dis
