Research and Development of the Remote I/O Data Acquisition System Based on Embedded ARM Platform

With the rapid development of the field of industrial process control and the fast popularization of embedded ARM processor, it has been a trend that ARM processor can substitute the single-chip to realize data acquisition and control. A new kind of remote I/O data acquisition system based on embedded ARM platform has been researched and developed in this paper, whose hardware platform use 32-bit embedded ARM microprocessor. This system can measure all kinds of electrical and thermal parameters such as voltage, current, temperature. The measured data can be displayed on LCD of the system, and at the same time can be transmitted through RS485 to remote System.
Proposed system:
The Proposed system involves the RS485 Protocol to communicate the data. The data is retrieved from the sensor and forwarded to a microcontroller. The ARM Processor establishes a RS485 protocol to a system in order to maintain the database.
