【摘要】：近年来,物流领域发展迅猛,民用物流领域正逐步的正规化、体系化,相关的监测网络体系建设也日趋完善,但军事物流等特种物流领域由于保密等原因发展缓慢。根据相关的法规,特种军事物品运输的整个过程都需要监控,目前完备的监控体系较少,而人员的监控往往存在遗漏和不及时等问题,所以特种物流领域对于远程在线监测系统具有很大需求。本文针对军事危险品物流运输过程缺乏监控的现状,尤其是军事弹药物资运输中存在的安全隐患,研制出一套基于北斗的物流监测仪,根据军事物流的特点,本系统设计了物资信息记录、物资定位与路径监控、温度在线监测等功能。本文研制的基于北斗的物流监测仪主要由监测终端和监控平台两大部分构成。在监测终端的设计中,先对当前物流监测领域的关键技术进行了分析,包括卫星定位、温度监测和数据通信等,并从中选择最适合本系统的技术应用到监测终端。设计的监测终端硬件上主要由北斗定位UM220模块、SIM900A发送模块、MSP430单片机控制模块等构成,实现方式是先由MCU控制北斗定位模块采集位置信息,再由MCU控制温度传感器模块采集温度信息,最后MCU将采集到的数据通过GSM模块发送到手机端和监控平台。监控平台存在于服务器端,由通信系统、监控系统、数据系统构成。通信系统接收监控终端送入的数据,并实时显示。监控系统包括位置信息、地图信息、用户信息,可以随时调用并显示。数据系统包括Web技术和百度的API服务技术。监测终端和监控平台两大部分都设计完成后进行了室内测试和室外测试。在室内测试中先对终端的各个模块进行测试。首先对AD590测温模块进行测试,从结果来看,在0℃~100℃范围内其线性度达到0.996,可以用于温度监测。再对终端的UM220北斗定位模块进行测试,从结果来看其定位精度达到3m,可以对120km/h的车辆进行秒级追踪。最后对SIM900A通信模块进行测试,从结果来看该模块能有效发送数据到手机端和监控平台端。监测终端工作可靠。然后将监测终端与监控平台进行联合调试,从结果可以看到,物资信息、位置可以有效实现实时在线显示。最后将测试终端拿到室外进行测试,从结果可以看到,在监控平台上能有效实现物资的定位、路径、管理信息查看等功能。基本满足了特种物流监测系统的设计要求,可以用于特种物流的在线监测。
[Abstract]:In recent years, the field of logistics is developing rapidly, the field of civil logistics is gradually regularization, systematization, and the construction of related monitoring network system is becoming more and more perfect, but the military logistics and other special logistics fields are slow to develop due to the reasons of confidentiality and so on. According to the relevant laws and regulations, the whole process of transporting special military goods needs to be monitored. At present, there are fewer complete monitoring systems, and personnel monitoring often has problems such as missing and not timely. So there is a great demand for remote online monitoring system in the field of special logistics. In view of the lack of monitoring and control in the transportation of military dangerous goods, especially the hidden dangers in the transportation of military ammunition and materials, this paper develops a set of logistics monitor based on Beidou, which is based on the characteristics of military logistics. The system designed material information recording, material location and path monitoring, temperature online monitoring and other functions. The logistics monitor based on Beidou is mainly composed of two parts: monitoring terminal and monitoring platform. In the design of the monitoring terminal, the key technologies in the current logistics monitoring field are analyzed, including satellite positioning, temperature monitoring and data communication, and the most suitable technology for the system is selected to be applied to the monitoring terminal. The hardware of the monitoring terminal is mainly composed of SIM900A sending module and MSP430 single chip microcomputer control module, which is mainly composed of the Beidou positioning UM220 module. The realization way is that the MCU controls the Beidou positioning module to collect the position information. Then MCU controls the temperature sensor module to collect the temperature information. Finally, MCU sends the collected data to the mobile phone and the monitoring platform through the GSM module. Monitoring platform exists in the server, which is composed of communication system, monitoring system and data system. The communication system receives the data from the monitoring terminal and displays it in real time. Monitoring system includes location information, map information, user information, can be called and displayed at any time. Data system includes Web technology and API service technology of Baidu. After the design of monitoring terminal and monitoring platform are completed, indoor and outdoor tests are carried out. In the indoor test, each module of the terminal is first tested. Firstly, the AD590 temperature measurement module is tested, and the linearity of the module is 0.996 in the range of 0 鈩，
