利用Windows提供的多窗口技术和通信事件,以及利用具有串行通信能力的智能化仪器,运用面向对象的程序设计方法,设计出相应的数据采集软件,并应用Windows环境下程序之间的数据交换技术,把数据实时采集与管理熔为一体,并赋予数据采集、监控和管理不同的窗口,实现数据采集与管理同步执行,操作直观方便。为了实现主计算机与多台智能化仪器的通信,首先须设计通信控制器,它相当于多路转换开关,按一定的优先级别响应仪器数据传输申请,建立与主机的传输通路;其次应当定义简单的实用的通信协议,并为主机、通信控制器和仪器编写响应的通信程序。
Utilizing the multi-window technologies and communication events provided by Windows, and using intelligent instruments with serial communication capabilities, the object-oriented programming method is used to design the corresponding data acquisition software and the data exchange between programs in Windows environment Technology, the data collection and management of real-time melting as one, and to give data collection, monitoring and management of different windows, data acquisition and management of synchronous implementation, intuitive and convenient operation. In order to achieve the main computer and multiple intelligent instrument communication, we must first design communication controller, which is equivalent to the multiplexer, according to a certain priority response instrument data transmission application, and the host to establish the transmission path; followed should be defined simple The practical communication protocol, and for the host, communication controller and instrument prepared response communication procedures.
