基于RS232的温度测量系统研究 一 引言 温度是一种最基本的环境参数，人民的生活与环境的温度息息相关，在工业生产过程中需要实时测量温度，在农业生产中也离不开温度的测量，因此研究温度的测量方法和装置具有重要的意义。本文介绍了一种基于RS232串口的数字温度传感器测温系统。 -RS232-based temperature measurement system 1 is a basic introduction to the temperature of the environmental parameters, the lives of the people and the environment temperature is closely related to the production process in the industrial needs of real-time measurement of temperature, in agricultural production can not be separated from the temperature measurement, The study of temperature measurement methods and devices is of great significance. This article describes an approach based on RS232 serial port of the digital temperature sensor temperature measurement system.

AB通讯程序不需要更改可以直接使用，RSLinx必须有授权否则无法通讯。 如果被挂起来可以考虑放到线程里面运行比较稳定，具体使用如有不清楚的可以打电话给我，后面有Delphi版和C版都不需要更改只要将PLC变量填入指定数组就可以读出和写入数据，Delphi版和C版相对复杂点但稳定性可移植性比较强适合做大程序 -The AB communication procedure does not need to change may use directly, otherwise RSLinx must have the authorization to be unable the communication.if is hung may consider that puts moves to the thread inside is quite stable, the concrete use like has not clearly may telephone to give me, behind has the Delphi version and the C version does not need to change, so long as fills in the PLC variable assigns the array to be possible to read out and the write data, Delphi version and C version relatively complex spot, but the stable probability is quite strong suitably to make big procedure
