【摘要】 介绍了Win2 0 0 0环境下利用Delphi和VB的通讯控件MSComm编写通讯软件 ,进行MSComm控件的属性设置和通讯端口初始化 ,通过MSComm控件的事件驱动方法及库函数MSComm .input()、MSComm .output()进行串口的捕捉和读写 ,实现温度巡检仪与PC机的串行通讯 ,并利用Delphi编制主控界面以实现通讯软件的智能化。实践证明该通讯软件传输数据准确、人机界面友好、使用方便更多还原

【Abstract】 The serial communication software between temperature data loggers and computer is introduced,which is realized with Delphi and VB’s communication widget MSComm under Win2000.The communication port’s initialization,serial port catching and read-writing which realized by the event-driven method of MSComm are described in detail. The intelligence of the software is realized by the main controlling interface programmed with Delphi.The practice proves that it is a convenient communication software which has friendly human computer interface and veracious data transmitting.更多还原
