Design Of Electric Power Equipment Check Point Machine

Equipment check point is a field that is in board knowledge and used widely. It is based on production effect and reliable maintenance of equipment. By the check point, it is able to find defects of equipment and abnormal status, to take countermeasure timely, to eliminate breakdown. Electric power equipment check point has important significance for equipment normal running, reducing maintenance cost and improving utilization of equipment.At present, check point machine exists several defects in high price, inconvenience purchase and maintenance in home enterprise. Furthermore check point machine drop behind in technique. High performance ARM7 processor and real-time operating system μC/OS-II were adopted in the design of check point machine. In some aspects such as cost, performance, running stability and anti-jamming etc, it is superior to traditional check point machine, and becoming an important implement in equipment check point.Firstly, the latest development of check point machine is analysed, and hardware design of the system is introduced detailedly in this paper. LPC2214 processor is choosen as core of electric power equipment check point machine, and the schematic of hardware design is also described.Then the software design scheme of the system is given in this paper. uC/OS-II is choosen as operate system of check point machine, and some module programs arelisted.Next the pattern of temperature measurement module is selected, and the design of software and hardware is discussed detailedly.Finally, check point machine is tested. The anticipated requirement such as information identification, non-contact temperature measurement and high resolution graphics user interface is achieved in check point machine.
