| Abstract: | A kind of multichannel temperature monitoring system which is rather high in the ratio of performance and price and also makes full use of the features of PLC is introduced.Under the conditions that there is not any need to increase the analog input modular numbers,the channel function numbers of the system to handle temperatures are expanded from 4 to 48 channels or even more and constant temperature control is also achieved.The hardware composition of the system,the main functionalities of each part and the design process of the system software are discribed in key points. |
