Problems solved by technology

The metal casings of cameras, infrared lamps, white light lamps, microwave radar speedometers and lighting search lights on the left and right sides of the read-write antenna will reflect radio frequency energy, weaken the total energy of the original radio frequency field strength, and greatly reduce the reading and writing distance. It is a device that violates the basic principle of UHF wireless transmission; in addition, the reflection of electromagnetic waves by the metal shell also changes the radiation direction of the original electromagnetic field, which actually fails to achieve the purpose of electromagnetic field forward emission
Finally, the external radio frequency identification part of the device only has a read-write antenna and is not integrated into an all-in-one reader. There will be loss or delay in the radio frequency signal communication link, and therefore it cannot be a complete radio frequency identification read-write Audit system

specific Embodiment 1

[0022] The first embodiment is that the all-in-one machine 10 is in a storage state. At this time, the supporting and telescopic folding arm 20 is reduced to the minimum and shortest form, and the universal rotating device 30 will adjust the parameters such as the direction, angle, position, level, and pitch angle of the all-in-one machine 10, so that it returns to the storage state, and the vehicle returns to the most stable state. Good aerodynamic properties.

specific Embodiment 2

[0023] In the second specific embodiment, the all-in-one machine 10 is in an extended state. At this time, the supporting and telescopic folding arm 20 relies on electric power, hydraulic drive or manual drive to raise upwards or shrink downwards. The mode of work of support and telescopic folding arm 20 is not limited, can be sleeve type ( figure 1 The case shown in), crank arm type, scissor type, spiral type, chain type, screw lift type, etc. At the same time, the all-in-one machine 10 can be adjusted in all directions through the universal rotating device 30 connected to the top of the telescopic folding arm 20. A universal rotating device can also be installed at the bottom of the telescopic folding arm to adjust the overall direction including the telescopic folding arm 20 and the all-in-one machine 10 .

specific Embodiment 3

[0024] Specific embodiment three, if the device needs to be equipped with cameras and other equipment, a horizontal bracket can be added on the top of the telescopic folding arm 20 and the universal rotating device 30 to form a "T" shape, and the integrated machine 10 and cameras and other equipment are placed at both ends of the horizontal support to form a physical and visual balance.

[0025] When the all-in-one machine 10 works in the extended state, it faces the vehicle to be tested to read and write the information in the electronic license plate label, and transmits it to the vehicle-mounted computer terminal and the peripheral device 50 through the data line connected thereto. The vehicle-mounted computer and the peripheral device 50 can If necessary, publish relevant information on the computer screen, or send this information to the background through wireless transmission means. Among them, when used in combination with a video recognition camera for vehicle or fixe...

Abstract

The invention provides a radio frequency identification reader-writer and antenna vehicle-mounted device. A radio frequency identification reader-writer and an antenna for transportation can be mounted on a police law enforcement vehicle and can be stored or stretched out; meanwhile, the stretching heights, the horizontal directions, the vertical directions and the pitch angles of the radio frequency identification reader-writer and the antenna can be adjusted according to requirements, so that the vehicle becomes a movable electronic number plate system read-write base station. The actual use feasibility and convenience of the vehicle-mounted device, the reader-writer and the antenna and the aerodynamic characteristics required for the vehicle-mounted device, the reader-writer and the antenna in the traveling process of an automobile are fully considered. The vehicle is a modern traffic enforcement vehicle which is small in occupied space and high in resource utilization rate. The radio frequency identification reader-writer and antenna vehicle-mounted device is mainly composed of a radio frequency identification reader-writer and reader-writer antenna integrated machine, a telescopic supporting folding arm, a universal rotating device, a controller, a vehicle-mounted computer terminal and a peripheral.

Description

technical field [0001] The invention relates to the field of vehicle-mounted special equipment in the transportation industry, in particular to a method of installing and fixing a radio frequency identification (RFID) reader and antenna for transportation on a vehicle, and thereby making the vehicle a mobile reading and writing base station for electronic license plates . Background technique [0002] In recent years, the National Safe City, Skynet Project, and Smart City have continued to make efforts. In response to the country's call for building a smart city, electronic license plate technology, as a branch of the Internet of Things industry, is combined with cloud computing to generate traffic big data, urban Big data is one of the hottest development directions at present. Car-related social activities have become the foundation of modern social and economic activities, people's livelihood development and urban construction. More and more city governments and traffic ...
