Design of Detection and Control of Oil mist Lubricating System

In order to well lubricate the industrial machine and decrease the consumption of lubricating oil, it is necessary to develop a system to monitor and control the density of oil mist. This paper introduces such a system based on LPC2214 of ARM7. The system can monitor 10 parameters, give an alarm to the status of factors which affect the quality of the oil mist and store the relative information into high capacity SD card through I2C bus and SPI bus. All the status information can be shown on LCD so that the operator can realize the system in real-time. System supplies input interface which can set some parameters and display other information on LCD, including history status information of system.
