Abstract:The long-range control system is more and more popular based on the network technology. It has many kinds of form with different function. But most of the control systems are unable to totally replace the stability and real-time character of the inside communication of industry control. In order to explore the characteristic, function and future improve; we regard air conditioner as a platform and design the long-range control device based on Internet. The control device set up with real-time character operation characteristic on the basis of steady high-speed network, which is not only has varies control function, and control opening, stopping, such functions as the mode is switched over of PLC, but also can change the data into ocular pictures, make the overall of air conditioner control digitization and visual. Moreover the function of the WWW network is special, which can share information of system WEB and only use standard IE browser technology. And achieve the control shift able and Global. in this article, introduce the Principle structure, Characteristic of controllable strategy, application software and system safety of the system. And explain by pictures, form and flow chart.
