Long-distance logistics freight vehicles 4G on-board wireless video surveillanceLong-distance logistics freight vehicles 4G on-board wireless video surveillanceSystem overview Long-distance freight car are prone to loss or damage to the goods along the way, the driver irregularities such as events, although many vehicles currently installed the GPS positioning system, can realize the function of the vehicle navigation and scheduling, but unable to video of the whole process of safety accident in the loss of or damage to the goods, such as case can't find the real reason.In addition, for logistics company's customer is very concerned about the goods shipping status, such as whether the goods is in what position, served in a timely manner, and when, etc., and should know these information, usually only through telephone enquiry or network access to information about, and logistics companies are struggling to cope with the customer about the goods to and quality of goods.As for the damage and loss of goods in transit, disputes over goods compensation often occur between logistics companies, customers and insurance companies due to the inability to provide evidence to distinguish the responsibility of the event. By installing on-board monitoring system on freight vehicles, the above problems encountered by logistics enterprises can be effectively solved.Compared with the current widely used GPS system, the vehicle monitoring system can not only track and record the geographical location of the vehicle, but also monitor and video the whole process of cargo transportation and loading and unloading, so as to prevent the loss of goods, but also can be used as evidence to distinguish the responsibility when the goods are damaged.With the help of GPRS/CDMA/EDGE wireless monitoring system, managers and customers can know the geographical location and transportation status of goods in real time through computers or mobile phones, so as to provide customers with better services and improve the competitiveness of logistics enterprises. Demand Analysis According to the requirements of users, make the following demand analysis: The analog video signal of the camera is changed into digital signal by the car host and transmitted to the video service center platform through 4G network;Monitoring management center personnel authorized by the center management server, can display the map, vehicle location, real-time image;
Design Principles 1, advanced in line with high starting point, high standard requirements, adopting international advanced 4 g video compression technology, computer network technology, communication technology, automatic control technology and management technology, and select the current has the international advanced level and the commercialization of the mature product, satisfy the digital application of the wireless video monitoring system and remote network management needs. In the design, we focus on the practical needs of the wireless video surveillance system application and emphasize the practicality of the system. Therefore, from the hardware platform and application software selection of the system, we ensure that the system has good comprehensive performance, and the system should have high efficiency. With the continuous expansion of the application scope of the 4G wireless video surveillance system, the construction scope will be gradually expanded and gradually built. Therefore, the system structure, capacity and processing capacity must have strong scalability, and the upgrade of the selected equipment products and application software should be strongly guaranteed. 4, the reliability of the system construction and put into use, will become the relevant administrative department of the daily work of indispensable tools, system paralyzed the consequences will be unimaginable, so the system must be stable run continuously, on the premise of single equipment is stable, reliable operation, focusing on fault tolerance design of the integrated system, thus ensuring the stability of the whole system. 5, security the system according to the needs of users, provide a variety of security measures and means to prevent various ways of illegal intrusion and confidential information leakage (including lightning protection, wind sand rain and moisture, anti-theft, etc.). The 4G wireless video surveillance system should ensure the coordination, stable operation, smooth information exchange among each work unit, and a certain fault tolerance and destruction resistance;At the same time, the use of international popular network video surveillance technology, products in line with international and domestic relevant industrial standards. 7, ease of use and maintainability in order to make the system built, can be easily used and managed.In the design, the priority should be given to the ease of use of the system, which should be easy to use, simple and easy to learn, easy to maintain;The key equipment in the system should have the functions of self-check and automatic recovery, power off protection, automatic alarm or isolation.
系統(tǒng)配置和技術(shù)要求
The system uses the international standard H.264 encoding method for image compression, storage and transmission. The system supports video traffic management commands to coordinate the network transmission requests of different users. Perfect user management mechanism can set password security authentication and operation rights for users, and only the personnel with relevant rights can enter the system and perform monitoring operations; The use of the monitoring system does not affect the normal operation of the monitored equipment;The monitoring system has high stability and reliability;The monitoring system can diagnose its own faults and automatically recover data disorder and communication fault. The system has a strong fault-tolerant ability, the system will not crash when the operation error, the system adopts an integrated structure, local errors will not affect the overall operation.The monitoring system has reserved ports for the convenience of system expansion.
中央智能調(diào)度監(jiān)控管理系統(tǒng)軟件
Each monitoring computer only needs a PC to install the car monitoring client software can realize network monitoring;A server must be added to the monitoring center for image forwarding and storage, and client software must be installed on the PC of relevant leaders for browsing and recording. Product Introduction: The video surveillance management software is the core of the network video surveillance management system. It takes high quality, high efficiency centralized, distributed network management as the architecture.Based on the network transmission of multimedia information, such as video, audio, and data, it performs real-time monitoring, video storage, and emergency warning for users.The car vision protection monitoring client software works closely with 4G car video recorder, making it possible for users to implement large-scale remote monitoring.The design idea of DVR plus network video server, which completely replaces the traditional security system, and the solution of sustainable update, may provide long-term investment protection for users. |
