The invention provides a multi-collection front-end bus management method and device, wherein the method comprises the following steps: the read-write backend sends control time stamp information to all the collection front-ends in the mode of only receiving and not sending on the bus, so that the The control time stamp information at least includes the gated time slice sequence and the gated time slice length where the corresponding collection front end is located; according to the gated time slice sequence, the corresponding collection front end is driven to open the interface connecting the bus communication in turn, and within the corresponding gate time slice length , the reading and writing back-end interacts with the corresponding acquisition front-end to realize radio frequency identification. The invention can realize the normal radio frequency identification of multiple acquisition front ends under the same bus, and effectively realize the function of multi-area identification such as roadside parking.
Description
technical field [0001] The invention relates to the technical field of radio frequency identification, and in particular, to a method and device for managing a multi-collection front-side bus. Background technique [0002] With the advancement of science and technology, especially the blessing of vehicle recognition technology, the current management of parking automation is in urgent need of technical transformation, so as to reduce manual intervention, improve parking efficiency, and achieve effective management of on-street parking and other scenarios. In Chinese Patent No. 201721696103.1, a multi-area identification-based RFID reader and roadside parking management system, a technical solution is described that can install acquisition front-ends in multiple areas, and a read-write back-end can implement unified identification management. like figure 1 As shown, a plurality of acquisition front-ends 20 are connected to the read-write back-end 10 through a bus for communi...
