Abstract:The command and control equipment composition is complicated, including many types of equipment. At present, the use and management of these equipment is mainly based on manual records. There are problems such as inaccurate records, large subjective factors, and many omissions. It is difficult to provide effective data support for equipment maintenance and guarantee. In response to these problems, the accusation equipment usage recording system based on power monitoring data is proposed. The system hardware is mainly composed of current sensor, single-chip controller and serial communication interface, and the software design is completed based on the CodeWarrior software development environment, which realizes the control of the Freescale single-chip controller ATD module and SCI module, and completes the data collection and transmission. Developed GUI interface based on MATLAB, completed data processing and status display function of sub-device. The system can complete the use record management of the entire complex equipment through a simple current acquisition and pattern matching process. Compared with the traditional method, the circuit design is simple, the status monitoring data is small, and the original working environment of the equipment will not be destroyed.
