摘 要

随着我国社会经济持续四十多年的蓬勃发展,社会对物流运输业务的需求量飞速上升,物流行业成为朝阳产业并取得了长足发展。经济的发展,使社会上出现了大量物资与人员运输需求,以往个体户单打独斗的单车运力运输模式不再满足社会需求,需要拥有一定规模的物流运输车队进行调运物资。在单车运输逐渐向物流运输车队运输转变的过程中,物流运输车队模式具有的规模性、集约性、高效性、信息化管理等优点日益突出,越来越受到大型物流企业的青睐。为了保障物流运输车队在行驶和作业过程中的交通安全,必然需要物流运输车辆之间及时的信息沟通,只有确保信息的正确传达,才能使整个物流运输车队获得及时的路况信息、安全提示、调度指令等信息,以便驾驶员能够及时收到信息,及时调整车辆,从而保障物流运输车队安全高效的完成调运物资的过程。传统的车辆交互信息手段存在诸多不足之处,如通信范围小、传输时效性差、协同效率低、交互性差等,难以保证物流运输车队的安全行驶和高效运作。

运用车载自组织网路技术在物流运输车队内组建链接网络,可实现物流运输车辆终端与物流运输车辆终端之间数据的传输。物流运输车辆间发送和接受数据,这些数据能够为所有物流运输车队驾驶员提供更多的道路车辆安全信息,为驾驶员驾驶决策提供可靠依据。由此可以预知,在车联网条件下实现车队的实时交互,能使行驶过程中的车队更加安全高效。

设计物流运输车队实时交互系统软件,需要考虑软件的使用对象以及应用的环境。

物流运输车队实时交互系统软件的使用对象就是物流运输车辆,该系统的目的是使物流运输车辆能够在道路上安全行驶。物流运输车队通常在道路是成队列的方式行进,在车队中除了第一辆领航的车辆是以巡航模式行驶外,其他车辆需要控制距离和车速跟随前方的车辆。在实际过程中会有出现掉队和有其他车辆混入车队中,还有物流运输车队前方发现发生交通事故需要躲避,以及物流运输车队内有车辆出现故障发出紧急报警信号的情况出现。这就需要获取车队内所有车辆的位置、速度以及感知到路况信息,为驾驶员提供更加全面的道路安全信息,辅助驾驶员做出正确的操作。

本设计使用的编程开发软件是Visual Basic,利用该软件编写的物流运输车队实时交互系统拥有五大功能,主要实现物流运输车队各项参数的查询,控制以及相关车辆的信息交互。具体功能(1)设置;(2)趋势图;(3)工具;(4)媒体;(5)车载互联。设置功能可以选择网络与端口,保证物流运输车辆的网络互联;趋势图功能将车速等信息直接转化为折线图显示在车载显示器上;工具能够实现日历时间查看,网络搜索以及日程提醒功能;媒体功能可以播放本地音乐;车载互联能够显示周围车辆的速度距离雷达图。

该软件主要通过实时交互物流运输车队的信息,并自动化的显示,可以简洁地显示出物流运输车队车辆的各项参数,同时与网络进行实时消息的对接,部分参数可由人为进行选择控制,更加准确的提供数据显示。

实时交互系统有助于整合物流运输车队的道路安全信息,为驾驶员提供更加全面的道路安全信息,降低途中风险,有助于提高运输整体的安全性,保障物流运输系统高效运行。

Real-time interactive system of logistics and transportation fleet for traffic safety

ABSTRACT

With the rapid development of China's social economy for more than 40 years, the demand for logistics and transportation business is rising rapidly, and the logistics industry has become a sunrise industry and made great progress. With the development of economy, a large number of materials and personnel transportation needs have appeared in the society. In the past, the single-vehicle transportation mode of self-employed people no longer meets the needs of the society, so a certain scale logistics transportation fleet is needed to transport materials. In the process of gradual transformation from single transport to logistics transport fleet, the model of logistics transport fleet has the advantages of scale, intensiveness, high efficiency and information management, which are increasingly favored by large logistics enterprises. In order to ensure the logistics shipping team to travel and work in the process of traffic safety, must need timely information communication between logistics transportation vehicles, only make sure to convey the information correctly, can make whole logistics convoys to obtain the traffic information in time, safety tips, dispatching command, such as information, so that drivers can receive information in a timely manner, timely adjustment of vehicles, to ensure safe and efficient logistics team to complete the process of dispatching goods. Traditional vehicle interactive information means have many shortcomings, such as small communication range, poor transmission timeliness, low coordination efficiency, poor interaction, etc., which are difficult to ensure the safe driving and efficient operation of logistics transport fleet.

By using the vehicle-mounted self-organizing network technology to set up a link network within the logistics transport vehicle team, the data transmission between the logistics transport vehicle terminal and the logistics transport vehicle terminal can be realized. The data sent and received between logistics transport vehicles can provide more road vehicle safety information for drivers of all logistics transport vehicles and provide reliable basis for drivers' driving decisions. It can be predicted that real-time interaction of the fleet under the condition of Internet of vehicles can make the fleet more safe and efficient in the process of driving.

To design the real-time interactive system software of logistics transportation fleet, the users and the application environment of the software should be considered.

The real time interactive system software of logistics transport fleet is used for the logistics transport vehicle. The purpose of the system is to make the logistics transport vehicle can drive safely on the road. A logistics transport fleet usually travels in a queue on the road. In the fleet, except for the first pilot vehicle driving in cruise mode, other vehicles need to control the distance and speed to follow the vehicle ahead. In the actual process, there will be straggling and other vehicles mixed into the fleet, as well as the occurrence of traffic accidents in front of the logistics transport fleet that need to be avoided, as well as the occurrence of emergency alarm signals for the breakdown of vehicles in the logistics transport fleet. Therefore, it is necessary to obtain the position, speed and perceived road condition information of all vehicles in the fleet, so as to provide more comprehensive road safety information for drivers and assist them to make correct operations.

This design uses the programming development software is Visual Basic, the use of the software prepared by the logistics transport fleet real-time interactive system has five functions, mainly to achieve the logistics transport fleet parameters of the query, control and related vehicle information interaction. Specific functions (1) Settings; (2) trend chart; (3) tools; (4) media; (5) vehicle-mounted interconnection. The setting function can choose the network and port to ensure the interconnection of logistics transport vehicles; The trend chart function directly converts information such as speed into line chart and displays it on the on-board display. Tools to achieve the calendar time view, web search and calendar reminder function; Media function can play local music; Vehicle-mounted interconnection can display the speed and distance radar map of surrounding vehicles.

This software mainly through the real-time interactive logistics transport team information, and automatic display, can be concise to show the logistics transport team vehicle parameters, at the same time with the network real-time message docking, part of the parameters can be controlled by artificial selection, more accurate data display.
