A multi-acquisition front-end bus management method and device

Abstract

The invention provides a multi-acquisition front-end bus management method and device. The method comprises the following steps of using a read-write rear end to send the control timestamp informationto all acquisition front ends on a bus in a mode of only receiving and not transmitting, wherein the control timestamp information at least comprises a gating time slice sequence and a gating time slice length corresponding to the acquisition front ends; sequentially driving the corresponding acquisition front ends to open interfaces connected with a bus for communication according to the gatingtime slice sequence, and within the corresponding gating time slice length, enabling the read-write rear ends to interact with the corresponding acquisition front ends to realize radio frequency identification. According to the present invention, the normal radio frequency identification of multiple acquisition front ends under the same bus can be achieved, and the function of multi-area identification of roadside parking and the like is effectively achieved.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification, in particular to a multi-acquisition front-side bus management method and device. Background technique [0002] With the development of science and technology, especially the blessing of vehicle recognition technology, the current management of parking automation is in urgent need of technological transformation, so as to reduce manual intervention, improve parking efficiency, and realize effective management of roadside parking and other scenarios. In Chinese patent 201721696103.1 RFID reader-writer and roadside parking management system based on multi-area identification, it describes a technical solution that can install acquisition front-ends in multiple areas, and uniformly realize identification management by a read-write back-end. Such as figure 1 As shown, multiple acquisition front-ends 20 communicate with the read-write back-end 10 through the bus, and the bus-ba...

Problems solved by technology

[0004] The purpose of the present invention is to provide a multi-acquisition front-end bus management method and device, which solves the technical problem in the prior art that the multi-acquisition front-end in the same bus interacts with the read-write back-end at the same time and causes conflicts, and cannot normally realize radio frequency identification.
