摘要
数据采集和控制软件系统采用串口通协议,实现了对4台蠕变实验机多点数据采集和数据的自动记录。遵循温度控制器的RS485通讯协议,软件系统可以自动调控蠕变高温炉的温度。通过OLE技术和人工代码,VB与Access、Excel无缝连接,将试验数据保存到Access数据库中。运行结果表明系统的软、硬件工作稳定,可靠性高,完全实现了蠕变实验机的温度自动控制和试验数据的自动记录。
Serial port communication protocol was introduced into the software system of data acquisition and control, multipoint data acquisition and data self-record of 4 creep testers were implemented. According to the RS485 communication protocol of the temperature controller, software system could autocontrol the temperature of the creep furnace. By means of the techniques of OLE and artificial code, the seamless integration among VB, Access and Excel were realized and the experimental results were saved into Access database. Operating results indicated that the hardware and software of the system are high reliability and stability, temperature auto-control and testing data self-record of the creep tester are completely achieved.
