Abstract: After research of the application of Internet of Things (IOT) in industrial control field, according to the monitoring terminal problems that large volume,low-capacity and simple function, a miniaturized, high-capacity, strong real-time, multi-parameter M2M monitoring terminal was designed and implemented. The terminal designed a basic control module, and the default for different applications and options that could be equipped with modules and applied more broadly. It achieved dynamic configuration of network interfaces and improved the versatility of the terminal. Learning from the traditional mode of data acquisition, the paper devised a prioritization scheme of data acquisition and data transmission, and discussed optimization algorithm. The results of applications show that it is a noticeable improvement in the index of system overhead and data transmission.
