基于物联网的港口设备监控与维护系统设计(任务书,开题报告,论文说明书16000字)
摘 要
我国经济的发展离不开港口的重要作用。科技的进步使港口不断朝着智能化、现代化、规模化的方向发展，港口设备也逐渐转向自动化、大型化、复杂化，吞吐量需求的迅猛增长和对港口功能升级的深层次要求导致港口业务很大程度上依赖大量现代化设备来完成货物中转。例如在港口码头的货物输送、尤其是散货装卸过程中通常依靠皮带输送机快速的将货物输送到指定位置。但是在港口发挥巨大作用的同时，港口设备在运作过程中也存在着许多隐患。据目前数据显示，我国很多港口设备都处于超期服役的状态，正如港口的皮带输送机在使用的过程中经常因为长时间高负荷运转,从而导致皮带输送机很容易出现故障,这严重影响了港口作业的执行效率。由此可见实时掌握港口设备的运行状态对提高港口的作业效率具有重要意义。
本设计便是基于物联网技术，针对港口皮带输送机常见的故障问题，来实现对港口设备皮带输送机实时状态的监测。系统中的各种传感器和保护开关为数据采集点，以STM32单片机为主控制芯片，结合无线WiFi技术，能够实时监测港口设备皮带输送机的运行状态，若设备发生故障，系统将及时报警停车，防止故障进一步扩大，确保设备和人员安全。设计中用到的各种传感器和保护开关由于其不便于仿真，所以用相应的模拟电路进行替代仿真。模拟电路分为开关量检测电路、比较量检测电路和模拟量检测电路。其中通信模块不能进行实时仿真，后面将会对其具体原理进行详细说明。 [资料来源：http://think58.com]

Abstract
The development of China's economy is inseparable from the important role of the port. The advancement of science and technology has made the port continue to develop in the direction of intelligence, modernization and scale. The port equipment has gradually turned to automation, large-scale and complicated. .The rapid growth in throughput demand and the deep requirements for port function upgrades have led the port business to rely heavily on a large number of modern equipment to complete the cargo transfer. For example, cargo handling at port terminals, especially bulk handling, often relies on belt conveyors to quickly transport goods to designated locations. However, while the port plays a huge role, there are also many hidden dangers in the operation of port equipment. At present, the data shows that many port equipments in China are in an extended service state. Just as the belt conveyors in the port are often used for long periods of high load during operation, the belt conveyors are prone to failure, this seriously affects the efficiency of port operations. It can be seen that real-time control of the operational status of port equipment is of great significance to improve the operational efficiency of the port.

This design is based on the Internet of Things technology, to achieve the real-time status of the port equipment belt conveyor for the common fault problems of the port belt conveyor. The various sensors and protection switches in the system are data collection points. The STM32 MCU is the main control chip. Combined with the wireless WiFi technology, it can monitor the running status of the belt conveyor of the port equipment in real time. If the equipment fails, the system will alarm and stop in time. Prevent further expansion of the fault and ensure the safety of equipment and personnel. The various sensors and protection switches used in the design are not easy to simulate, so the simulation is performed with the corresponding analog circuit. The analog circuit is divided into a switch quantity detection circuit, a comparison quantity detection circuit, and an analog quantity detection circuit. The communication module cannot perform real-time simulation, and the specific principles will be described in detail later. [资料来源：http://think58.com]
