1. Project background
In order to effectively safeguard the interests of various investment owners and resolve the path ambiguity, path identification is gradually transitioning from probability identification to precise identification. Among the precise identification technology, RFID technology has great advantages and development space compared with other methods, and it is the trend and direction of future path identification system development.
The Zhejiang Ambiguity Path Recognition System was developed in this informationized and networked environment, which is in line with the development trend of the toll system. The second phase of the project plans to build a basically complete path identification system for account splitting, using precise RFID path methods.
In order to cooperate with Zhejiang’s ambiguity construction, ZTE has developed a composite toll card OBU, a roadside identification station RSU, and a composite reader/writer ODU, and launched a full line of products to support Zhejiang’s ambiguity construction. Compatibility with Phase I was fully considered in the system design. At present, the construction of the project has entered the final stage. All three devices have passed strict stress tests. The overall road network runs smoothly, reaching and exceeding the owner’s expected goal.
2. The overall framework of the system
The ambiguous path identification system is composed of the roadside identification station subsystem, the road section center monitoring and management subsystem, and the management center monitoring and management subsystem. The roadside marking station subsystem completes the function of writing the path information of the on-board unit carried by the vehicle, including: roadside marking unit, desktop unit, composite pass composition; roadside marking station subsystem; road section sub-center monitoring management subsystem can monitor The status of the roadside marking station subsystem, and forwarding the control instructions issued by the management center subsystem to the roadside marking station; besides communicating with the road section sub-centers, the management center monitoring management subsystem can also use the mobile communication network to directly communicate with the road. The side identification station communicates, monitors the state of the roadside identification station subsystem, and sends control commands to it. In addition, the management center splits and settles tolls according to the actual driving path of the vehicle, and completes the functions of information inquiry and instruction sending.
3. Program features
Double wake-up mechanism, high system identification success rate
The system adopts the dual wakeup mode of wakeup on entry and wakeup on the road. Under the condition of ensuring low power consumption, the identification success rate is improved.
Strict security mechanism to ensure reliable and safe transactions
The system adopts strict safety control mechanism. Strict encryption and decryption algorithms are used at the entrance to ensure safe transactions. In addition, under the existing design framework, the composite pass card can implement a soft encryption module on the software, and data verification operations are added during the data interaction process.
With status monitoring, it is convenient for remote maintenance and management
The system provides carrier-class network management functions. The roadside marking station has good network support capabilities, and can be conveniently configured and networked through network management tools. Through the network configuration software on the server or local command line debugging tools, all roadside identification stations in the network can be configured and managed, remote version management, PSAM management, business diagnosis, alarm management, and remote version upgrade of the device is supported.
Adapt to a wide temperature, support complex application environment
The equipment uses industrial-grade components to ensure high sensitivity and high reliability in a wide temperature range from -20°C to 65°C.
7×24 hours of continuous operation throughout the year
ZTE’s equipment has passed the global professional technical index certification in terms of reliability and stability, and has passed EMC testing, environmental adaptability testing, national vibration testing, and international CE certification. The system adopts an embedded operating platform with higher stability and safety to ensure stable operation 7×24 hours throughout the year.
Perfect after-sales service guarantee system
The customer service system of ZTE Corporation is responsible for the pre-sales, in-sales and after-sales services of the company’s products, and is committed to continuously improving the quality assurance construction of the service system, and has formed a distinctive service method. ZTE has set up 33 offices in China, which are fully responsible for the engineering maintenance and technical consultation of ZTE products. All service organizations have been connected to the company’s headquarters LAN, which can provide customers with high-quality services quickly and accurately.
