[Abstract]:In view of the common fault characteristics of the rocker arm of shearer, an on-line monitoring and warning system for the safety of the rocker arm of shearer based on STC single chip computer is developed in this paper. In this system, the data acquisition, data transmission, data storage, data display and safety warning of the key components of the rocker arm of the shearer are realized by means of multi-channel signal acquisition technology, bus communication technology and so on. The system is mainly composed of three parts: hardware test system based on STC single chip computer, software programming of lower computer and management of industrial upper computer. The whole test system includes: main control chip, multi-channel data acquisition module, data storage module, analog-to-digital conversion module, serial communication module, thermocouple cold end compensation module. The power module. STC single-chip computer is installed on the rocker arm of the shearer in a modular manner. Each module contains a plurality of sensor analog interfaces and its data conversion. The data are converted and processed one by one after the multi-channel analog switching. The data storage unit stores the data collected and processed by single chip computer, records the change of temperature in the specific position of the rocker arm of the shearer at a specific time, and provides the monitoring data for the safety and early warning function of the monitoring system. The data collected by the front-end module is transmitted to the upper computer touch screen through RS485 communication for real-time display and fault analysis. The software programming of lower computer mainly includes A / D conversion, data processing, fault detection, serial communication and so on. The upper computer of this system adopts touch screen based on MCGS configuration software, including sensor calibration module, data display module, history data module, curve query module, early warning parameter setting module and alarm module. The touch screen realizes the serial communication with the lower computer according to the Modbus communication protocol. In this paper, the hardware circuit design and debugging of the monitoring system, the software programming and debugging of the lower computer, the interface design and data processing of the industrial touch screen of the upper computer are completed. This monitoring system has realized the user's function request to this system.
