It develops a wireless sensor network for mining belt conveyor transportion process monitoring and controlling system based on Zigbee. This system establishes a low cost,self-organizationand low power consumption for large belt conveyor process monitoring of wireless sensor network. Based on Chipcon CC2530 Radio-on-Chip for Mobile and TI company DSP microprocessor chips TMS320LF2406A,it realizes the information transmission between mining belt machine sensor and sensor,and underground monitoring information transmission between the RACES. The wireless sensor networks with convenient expand can avoid the traditional cable way set point decorate difficulty,and have low system maintenance cost. This method can be applied on other conditions in the mining and related industries.
It proposes an efficient XML data encoding scheme based on bit pattern to solve the problem such as lower space efficiency and complex processing.This encoding scheme has the characters of dictionary order,certainty and compression to meet the requirements of efficient XML encoding scheme.It identifies the level of encoding algorithm and develops the code generation algorithm for static parsing and dynamic updating.
由于带式输送机运输原煤路线长、生产环节多、工艺复杂、运输量不均衡,造成生产线用人多、频繁停车等弊病,如不能实时对皮带控制系统中发生的故障进行处理,将导致皮带运输系统不能正常运行,直接影响煤矿生产和威胁井下人员的安全。本文设计出一种运行安全可靠,高效率,高技术水平的皮带机电控系统,系统利用32位ARM微处理器LPC2132为控制器,结合了ARM微处理器的高性能低功耗的特点,设计了集控制、保护于一体,具有数字化、操作便捷、响应速度快、处理能力强、抗干扰能力强、可靠性和稳定性好的特点。
Coal mine security monitoring system is important guarantee for efficient production of coal mine.The terrible envieonment of coal mine,the wide distribution of weak current equipment and large energe consumption,especially high-frequency devices will bring interference signal to system.Thereby increasing anti-jamming capability of mine monitoring system is most fundamental development path of China coal mine safe production.
