[Abstract]:At present, communication technology, electronic information technology and industrial control technology are developing rapidly. In order to protect the people's personal safety in the dangerous and complex environment of large engineering machinery operation, more and more wireless remote control devices appear in the production line. But at the same time, the maintenance of industrial equipment and the positive fault diagnosis are positive. In the face of more and more challenges, it is necessary to have a detailed grasp of their real time status so as to find out the problems in time and help to establish the operation and maintenance scheme. Based on the vehicle intelligent monitoring system based on Mesh network, this paper designs and implements a handheld monitoring unit, with a good HMI man-machine interface, and can not cover the signal of the base station under the mine. In the area, the vehicle carries on the real-time state information monitoring, the locomotive history record collection, the emergency control locomotive and the important control quantity configuration and the sending and other tasks. It solves the problem that the vehicle state monitoring can not be carried out in the underground signal blind area. The handheld monitoring unit uses the LPC1768 core control chip. The user is based on the menu page on the screen. The task instruction is to be performed by the communication protocol group. The C02128 communication chip transmits the data transparently to the target device. After receiving the reply, the handheld monitoring unit is extracted and displayed on the specified location of the LCD screen to complete the design of information acquisition and communication control tasks. Meanwhile, the handheld monitoring unit has the off-line number. According to the import function, the collected locomotive data can be imported into the upper computer monitoring software through the RS-232 interface. This paper first introduces the research background, the domestic and foreign research status and the expected research goals. Secondly, the whole architecture and the main functions of the vehicle intelligent monitoring system based on Mesh network are described in detail, and the wireless Mesh network and A are also introduced. D-Hoc network is introduced, and then from the hardware of the whole system, the design of Flash, EEprom storage, power supply, key switch machine and RS232 interface are designed, and then the modules of data storage, menu structure, task event management, transmission and communication mode and whole process are designed for the software platform; and then according to the handheld monitoring unit Function requirements, design communication protocol, HMI human-computer interface and upper function software processing logic respectively. Finally, the whole subsystem is tested and result analysis. The actual test results show that the HMI man-machine interface design is clean and reasonable, the page switch runs fluently, and the functions of information collection, instruction, and data upload are realized with the communication protocol. To achieve the desired design goals.
