Description

technical field [0001] The invention relates to the technical field of radio frequency acquisition equipment, in particular to a multi-channel coverage radio video acquisition equipment and method. Background technique [0002] Radio Frequency Identification (RFID) technology is a wireless communication technology that can identify specific targets and read and write related data through radio signals without establishing mechanical or optical contact between the identification system and specific targets. RFID technology is used in many industries, such as attaching a tag to a car in production, so that the factory can track the progress of the car on the production line, the warehouse can track the whereabouts of medicines, and the RFID identification card can make employees Can enter locked building parts, and the radio frequency transponder on the car can also be used to collect toll roads and parking fees; at present, the proportion of non-motorized vehicles such as two...

Problems solved by technology

RFID technology is used in many industries, such as attaching a tag to a car in production, so that the factory can track the progress of the car on the production line, the warehouse can track the whereabouts of medicines, and the RFID identification card can make employees Can enter locked building parts, and the radio frequency transponder on the car can also be used to collect toll roads and parking fees; at present, the proportion of non-motorized vehicles such as two-wheeled electric vehicles and motorcycles in the city is increasing , there are more and more illegal driving behaviors when passing traffic lights, such as running red lights, occupying motor vehicle lanes, occupying sidewalks, etc., causing frequent traffic accidents in traffic-intensive areas. Motor vehicles and non-motor vehicles require multiple devices to be used separately, the cost is high and the weighing capacity of the pole frame is also high, which affects the large-scale promotion of RFID readers
