[Abstract]:In view of the characteristics of complex mine wiring and difficult maintenance, combined with the current ZigBee wireless sensor network technology, this paper proposes a design scheme of mine gas monitoring system based on ZigBee technology. First of all, consult a large number of coal mine safety references, understand the current mine safety monitoring deficiencies in China, according to the system function needs and performance indicators, combined with ZigBee wireless sensor network technology, The overall design scheme of underground gas monitoring system based on ZigBee technology is put forward. The hardware of the system is selected and the appropriate ZigBee protocol stack is selected. Secondly, according to the overall design of the system, the hardware circuit of the gas monitoring system is designed in detail. This includes three parts: the first part is the hardware design of the monitoring node, including the design of the interface circuit between the microcontroller and the RF, the interface circuit of the sensor interface circuit and the LCD LCD module interface circuit, the circuit design of the power supply module. The circuit design of acoustooptic alarm module and the interface circuit of downloading and debugging JTAG program. The second part is the hardware design of receiving node, which mainly includes peripheral circuit design of CC2430 RF chip, serial communication circuit design. Key interface circuit design LED state indication circuit design, extended interface circuit design; the third part is node PCB design and hardware production. Thirdly, according to the working principle of the hardware circuit, the software interface driver is written. It mainly includes monitoring node sending data driver, sensor module collecting data driver, LCD module displaying driver, power voltage detecting and low power processing driver, receiving node receiving data driver. PC serial communication driver. Then the software and hardware of the system are comprehensively debugged and the debugging results show that the designed software and hardware system can collect data correctly. Finally, a monitoring software based on Delphi is designed, which can be used to intuitively observe and analyze the data collected and sent by monitoring nodes. The creation of Delphi database, the creation of database table structure and the technology of database access are introduced. The user login management, monitoring object management, data real-time monitoring and data query are realized by using Delphi integrated development environment. Data processing and data output and other functions. After running debugging, all functions can receive and process data correctly.
