【摘要】：从古至今,仓库一直都是社会物资供应体系的核心组成部分,对物资的存储发挥着无可替代的作用,因此对仓库的维护和管理是十分有必要的。由于仓库普遍具有货物存储量大、通风不畅和地处偏僻的特点,所以防火、防潮和防盗一直都是仓库日常管理的重要内容。为了预防仓库货物遭受损失,人们通过监测有参考价值的仓库环境信息提前预判事故的发生。但是传统的仓库监测系统一般都是采用RS485或CAN总线传送数据,这些方法存在着成本较高、老化、布线不便、容易受雷击等问题,影响了其可靠性。针对上述问题,论文设计了基于ZigBee的仓库环境监测系统,该系统能够对仓库的温度、湿度和人员入侵信息进行感知,同时利用无线通信方式将信息传送到上位机以供管理人员判断参考。论文特别针对一些盗窃份子为躲避系统监测而故意破坏终端节点的现象设计了节点掉电判断程序,一旦节点断开网络,其它节点会同时报警,并将断开网络的节点号显示出来,管理人员通过系统能够第一时间得知事故发生位置从而做出及时处理。论文首先对ZigBee技术的概念与特点进行了简要介绍,阐述了网络结构和协议规范中每一层的职能作用与工作流程。然后提出了系统的整体设计方案,以设计方案为基础搭建硬件平台,同时对ZigBee节点进行了硬件设计。基于相关软件,论文对网络节点的掉电检测、温湿度采集、入侵报警和上位机界面等程序进行了设计。最后,对整个网络进行了测试,包括网络建立、协调器和终端节点的功能实现、上位机界面程序以及通信距离等测试。
[Abstract]:Since ancient times, the warehouse has been the core part of the social material supply system, which plays an irreplaceable role in the storage of materials, so it is very necessary for the maintenance and management of the warehouse. Because warehouses generally have the characteristics of large storage of goods, poor ventilation and remote location, fire prevention, moisture prevention and theft prevention have always been important contents of warehouse daily management. In order to prevent warehouse goods from losing, people prejudge the occurrence of accidents by monitoring the reference information of warehouse environment. However, the traditional warehouse monitoring system generally uses RS485 or CAN bus to transmit data. These methods have some problems such as high cost, aging, inconvenient wiring, easy to be struck by lightning, and so on, which affect their reliability. Aiming at the above problems, the paper designs a warehouse environment monitoring system based on ZigBee, which can perceive the temperature, humidity and human intrusion information of the warehouse. At the same time, wireless communication is used to transmit the information to the host computer for the manager to judge the reference. In this paper, a node power failure judgment program is designed to avoid system monitoring. Once the node disconnects the network, other nodes will alarm at the same time, and the node number of the disconnected network will be displayed. Through the system, managers can know the location of the accident and handle it in time. Firstly, the concept and characteristics of ZigBee technology are briefly introduced, and the function and workflow of each layer in the network structure and protocol specification are expounded. Then the whole design scheme of the system is proposed. The hardware platform is built on the basis of the design scheme. At the same time, the hardware design of the ZigBee node is carried out. Based on the related software, the paper designs the programs of network node power failure detection, temperature and humidity collection, intrusion alarm and upper computer interface. Finally, the whole network is tested, including network establishment, function realization of coordinator and terminal node, upper computer interface program and communication distance test.
