[Abstract]:With the rapid development of science and technology, mechanical equipment is becoming more and more large and complicated. To be able to grasp the field operation status of mechanical equipment at any time, anywhere, and to detect and evaluate the current operating state of the equipment has become the focus of attention of various industries. Based on the traditional measurement and control system, the remote monitoring system is developed by combining the current information processing technology and wireless communication technology. It overcomes the need of the traditional measurement and control system to set up wired transmission lines. It is easy to be restricted by complex terrain and harsh field conditions, and its mobility is poor. The mobile terminal equipment of remote monitoring system adopts Linux operating system with embedded ARM as the core, which greatly improves the performance of the system, reduces the power consumption of the system, and realizes the intelligent control of the system. Wireless communication technology is used to transmit the data collected in the field, and the data can be interacted with the remote data center in real time and reliably. This paper designs and implements a new kind of mobile terminal equipment of remote monitoring system. The mobile terminal is based on S3C2440 microprocessor based on ARM920T kernel and embedded Linux operating system. On this basis, the functions of identity identification and wireless communication are added. Identification is realized by UHF radio frequency identification module. The reader recognizes the electronic tag and reads and writes radio frequency signals to complete the identification work. Wireless communication is realized through WIFI wireless network. In the process of data communication, WIFI is connected to remote data center and data is exchanged. In this paper, the necessity of the application of embedded mobile terminal based on Linux in remote monitoring system is studied and analyzed from the theoretical point of view. According to the actual requirements, the overall system scheme based on radio frequency identification (RFID) and wireless communication is designed. Then the hardware part and the software part of the mobile terminal system are described. Finally, the hardware and software test platform of the mobile terminal is built to test the function modules of identity identification and wireless communication, respectively, to verify the feasibility of the design.
