Problems solved by technology

[0005] However, if the wireless repeater RP is in the receiving state for a long time, its battery will be consumed too quickly, which will seriously shorten the service life of the battery. This requires the staff to regularly maintain and replace the wireless repeater RP, increasing the service life maintenance cost and usage cost

Abstract

The invention provides a data transmission method, device and system. The data transmission method comprises the steps of, by a relay, obtaining configuration information sent by an upper-end device,wherein the configuration information at least comprises a master-slave relationship among multiple vehicle detectors matched with the relay and a reception time bucket used for receiving event information sent by each vehicle detector; if the event information sent by a master vehicle detector is received in a first reception time bucket corresponding to the main vehicle detector based on the configuration information, waking up a second reception time bucket corresponding to a slave vehicle detector which is associated with the master vehicle detector so as to receive the event information sent by the slave vehicle detector in the second reception time bucket; sending the received event information to the upper-end device; and enabling the first reception time bucket of the master vehicle detector to be opened in real time, and determining whether to wake up the second reception time bucket based on the data received in the first reception time bucket. Through the way abovementioned,the accuracy and comprehensiveness of the received data can be guaranteed, the battery consumption can be saved, and the purpose of low power consumption is realized.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular, to a data transmission method, device and system with low power consumption. Background technique [0002] In the field of intelligent transportation, the use of buried wireless vehicle detectors to monitor traffic conditions in real time can provide real-time and accurate traffic condition information for traffic signals or monitoring platforms. [0003] In actual use, in order to provide more complete and comprehensive road condition information, in addition to laying out buried vehicle detectors near the stop line at the intersection, multiple detectors are usually placed in the road section upstream of the road (the upstream of the road is the entrance of the lane). Vehicle detectors to detect important parameters such as traffic flow, driving speed, and queue length in road sections that reflect road conditions. In order to increase the distance of wireless ...
