Vehicle identification system and method

Abstract

The invention relates to a vehicle identification system and method. The system comprises a vehicle-mounted extension unit connected with a master unit; the mater unit is connected with a PC machine; and the PC machine is connected with a net-connected computer of a traffic management department by a wireless public network. An identification management control master unit consists of an ultrasonic transmitter and an information processor, wherein the ultrasonic transmitter and the information processor are connected. Besides, a top hollow cylinder is also arranged; and the bottom of the top hollow cylinder is connected with a bottom hollow cylinder. With the method and system, a defect that the correctness and the storage operation of the storage device for storing information of a license plate number and a vehicle type as well as the flow and cost are affected by the time delay due to a long conveying line and data transmission incompatibility of a plurality of media for data transmission in the prior art can be overcome. Therefore, particle impurities removing and cooling of an information processor of the identification management control master unit can be realized; and thus the information processor of the identification management control master unit can be in a normal heat adjusting environment for long time.

Description

technical field [0001] The invention belongs to the technical field of vehicle identification, and in particular relates to a vehicle identification system and method. Background technique [0002] Vehicle identification system with electronic ID card mode. It consists of three parts: vehicle-mounted extension unit, identification management control host part, and electronic ID card issuance and management part of the transportation department. The vehicle-mounted extension part consists of an electronic ID card that can store information such as vehicle model and vehicle number, a short-distance radio frequency transceiver, an ultrasonic receiver, an RFID reader, and equipment with functions such as displaying information and calling for emergency help. And send out a signal with a special frequency, and respond with the host. The identification management control host is composed of an ultrasonic transmitter connected to an information processor. The host assigns a fixe...

Problems solved by technology

[0004] With the widespread use of information collection systems for vehicle numbers, models, traffic and costs, this has greatly improved the information monitoring level of vehicle numbers, models, traffic and costs. In addition, vehicle numbers, models and traffic The collection of information on fees and charges has already become popular in the case of remote communication. The storage of vehicle number, model, flow and fee information is placed in the networked computer of the traffic control department, but with the vehicle number, model and flow With the increasing frequency of information collection and expenses, the amount of information data on vehicle numbers, models, traffic and expenses is increasing, while the existing information storage for vehicle numbers, models, traffic and expenses The networked computers of the traffic control department often have a delay in the delivery time due to the distance of the transmission line, and the incompatibility of some data transmission media in data transmission, all of which affect the vehicle number, model, traffic and cost. The correctness of the storage device of information and the operation of the storage have adverse consequences

[0005] The host is an important part of the vehicle identification system, which can realize the very important task of the vehicle identification system, but the particulate impurities in the environment often stick to the wall of the information processor of the identification management control host, causing damage to the information processor , and will also lead to the formation of communication with the ultrasonic transmitters connected to it, and even endanger them so that they cannot cooperate with each other normally; in addition, a large amount of particulate impurities stuck to the information processor of the identification management control host will also affect the identification management control host The cooling of the information processor is disturbed, so that the information processor of the identification management control host will always run under the condition that a large amount of heat cannot be removed, and the information processor of the identification management control host will be damaged, so it is necessary to let the identification management control host The information processor of the management control host realizes the removal of particulate impurities and cooling, so that the information processor of the identification management control host can maintain a normal heat regulation environment
