The Design And Implementation About Complex Equipment Simulation Monitoring Platform Based On ARM

Complex equipment as the core between the great powers of the game, it is also a backbone to a national equipment manufacturing. The research of complex equipment monitoring platform has a very important significance to ensure the safe operation of complex equipment and promote the development of the equipment manufacturing industry in our country.In recent years,with the development of advanced technology and its application in complex equipment,the performance of the complex equipment has been improved, but its complexity has increased a lot too, and produced a high failure rate, what’s more made a serious impact on the complex equipment working efficiency. Therefore, a simple and fully functional operation of the monitoring platform for the existing equipment manufacturing industry is particularly important, and the accuracy and real-time of information in the monitoring process is one of the important criteria to judge whether a monitoring platform is good or bad.Aiming at some shortcomings of previous monitoring platforms, according to the characteristics of monitoring platform for the accuracy of monitoring information and high real-time requirements, this paper designs a complex equipment simulation monitoring platform by using ARM processor which based on CAN bus technology. By taking ARM as the main controller and applied the bitwise arbitration mechanism of CAN bus to the design of the monitoring platform, using the characteristics of Linux system hardware and software can be cut out, the strong display function characteristics of qt-embedded, to design an economy and actual effect of complex equipment simulation monitoring platform. The simulation monitoring system consists of Linux kernel transplantation, the root filesystem production, qt-embedded application design, MCP2515 driver design under Linux and the design of hardware and software components about three node signal acquisition module.The hardware platform consists of Feiling OK2440 development board, three signal acquisition module node of which two STC89C52 microcontrollers as the node controller and a STC12C5A60S2 microcontroller as the other node controller. The three signal acquisition node module respectively transmits the analog signals, the digital signals and the switching signals to the main control platform via the CAN bus which are collected by different instructions from the main controller. According to different types of signal, the main controller carries out their own acceptance filter and shield processing. The monitoring platform will monitor the signal state information in real-time and accurately display the corresponding interface on the LCD.At the end of this paper. By using the complex equipment simulation monitoring platform to complete the simulation condition monitoring for pump vehicle, the experimental results show that the designed simulation of complex equipment monitoring platform can simulate the common information collection and display function of pump vehicle running state monitoring process, which is basically in accordance with the requirements of the paper.
