【摘要】：随着全球工业的迅速发展，缓冲器作为安全保护装置已被广泛运用于起重设备当中。它能减少生产事故的发生，保证生产人员的安全。但是，，长期高强度的对缓冲器进行机械碰撞，容易使缓冲器老化磨损，并出现缓冲器被撞击后复位异常的情况，严重影响其缓冲能力。而人工检测缓冲器的复位情况工序繁琐、效率低下。为此，探索研制一套自动检测监控系统代替人工手段检测非常有现实意义。本文针对起重机缓冲器复位距离的检测要求而展开，设计出一套基于ZigBee无线网络技术的缓冲器检测系统。具体而言，通过对现有起重机缓冲器故障检测方法进行分析和对比研究，选出缓冲器复位距离为检测对象，并选用HC-SR04超声波测距传感器模块+DS18B20温度传感器模块实时精确的测量缓冲器动作后的复位距离。然后进一步分析无线传感器网络技术的基本原理，并通过比较几种时兴的无线技术，选出成本低、功耗小、传输质量高的ZigBee无线通信技术作为本文的无线应用方案。其中，无线射频芯片选用TI公司的CC2530芯片作为ZigBee无线通信模块的硬件解决方案，并具体设计了无线通信模块CC2530的应用电路及无线通信模块与上位机、微控制器的接口电路。此外，本文在详细分析了ZigBee协议栈的体系结构及工作流程的基础上，设计出一套缓冲器检测组网程序。最终实现对起重机液压缓冲器的实时检测监控。最后，对全文进行了总结，指出了本系统的还存在的问题，对下一步的研究工作进行了展望。
[Abstract]:With the rapid development of global industry, buffer, as a safety protection device, has been widely used in lifting equipment. It can reduce the occurrence of production accidents and ensure the safety of production personnel. The mechanical impact on the buffer with high strength for a long time is easy to cause aging and wear of the buffer and abnormal reset after the bumper is struck. The reset process of manual detection buffer is tedious and inefficient. Therefore, it is of great practical significance to explore the development of an automatic detection and monitoring system instead of manual detection. Aiming at the requirements of crane buffer reset distance detection, this paper designs a buffer detection system based on ZigBee wireless network technology. Through the analysis and comparison of the existing crane buffer fault detection methods, the buffer reset distance is selected as the detection object. And select HC-SR04 ultrasonic ranging sensor module. The DS18B20 temperature sensor module can accurately measure the reset distance after buffer operation in real time. Then the basic principle of wireless sensor network technology is further analyzed. By comparing several popular wireless technologies, ZigBee wireless communication technology with low cost, low power consumption and high transmission quality is selected as the wireless application scheme of this paper. The CC2530 chip of TI company is chosen as the hardware solution of ZigBee wireless communication module. The application circuit of wireless communication module CC2530 and the interface circuit of wireless communication module with host computer and microcontroller are designed. Based on the detailed analysis of the architecture and workflow of the ZigBee protocol stack, this paper designs a set of buffer detection and networking program, and finally realizes the real-time detection and monitoring of the hydraulic buffer of the crane. Finally, the paper summarizes the full text, points out the existing problems of the system, and looks forward to the next research work.
