Plate mills hydraulic system is made up of several hydraulic stations, lubrication stations and grease stations, these hydraulic stations and lubrication stations are distributed around the mills. Each hydraulic station possesses qualities of successive long working time, high reliability and signal complexity, and it can satisfy diverse demands of high grade pressure or temperature control, etc. This paper is based on these demands, assembling control missions of hydraulic and lubricating stations. Several PLC S7-300 were chosen to match the need of controlling mills hydraulic and lubricating system for a certain plate factory, and the HMI monitoring system for mill hydraulic and lubricating stations was developed by WINCC, which achieved central control and monitoring the hydraulic and lubricating system of plate mills.

Abstract. To improve the automation degree in special working environment which contains explosive gas. We develop a new type of temperature control hydraulic sensor basically on theory and lots of experiments. As the temperature reaches about 85°C，the motion part of the inductor will stretch to a certain length, and then it will push the adjusting rod. Simultaneously，the adjusting rod will overcome the elastic force of the spring and compel the spool valve to deform, and finally the control valve port will be open, it allows the control oil of the hydraulic system to pass. At last it reaches our destination that we can make the control of hydraulic circuit be realized.

As it is impossible to conduct real-time monitoring on slope condition of highways, a remote monitoring system has been specially designed. Making use of GPRS technology, Labview and solar power, the system has realized nobody monitor on slope anchor system, automatic collection of slope pressure and displacement data. It enjoys advantages such as high-accuracy, real-time monitoring and high-reliability. Among existing effective monitoring ways, massive man-power is needed for on-field work, but real-time monitoring is still left to be achieved.
