Transmission time sequence monitoring method and device for sensor data

Abstract

The embodiment of the invention discloses a transmission time sequence monitoring method and device for sensor data. The method comprises the steps that time information corresponding to each piece ofcollected sensor data is obtained, and the time information is calibrated time information when the sensor data passes through a preset transmission node in a data collection system in the data collection process; based on the time information corresponding to each piece of sensor data, and a preset time range, whether data transmission between every two predetermined transmission nodes is abnormal or not is determined, wherein the preset time range comprises a preset transmission time range required by data transmission between every two preset transmission nodes and / or a preset sensor sampling period, so as to monitor the data acquisition process and position in time to obtain a specific abnormal position.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular to a method and device for monitoring the timing sequence of sensor data transmission. Background technique [0002] In related technologies, the data collection system uses the map collection vehicle to collect data, generally as follows: the map collection vehicle obtains sensor data through the installed sensors; and transmits the obtained sensor data to the data collection system through various transmission protocols The acquisition device; the acquisition device receives the sensor data transmitted by the map acquisition vehicle through its receiving node; and processes the received sensor data through its data processing node to obtain the processed sensor data; furthermore, through its data publishing node, it will The collected data is distributed to subscribers to realize the collection of sensor data, wherein the collected data includes: sensor data and / ...

AI Technical Summary

Problems solved by technology

In the above data collection process, due to the existence of many nodes, it is easy to cause delay and blockage of the collected data, and the occurrence of the above situation will affect the quality of the collected data

[0003] In order to ensure the quality of the collected data, it is very important to monitor the data collection process and locate the location of the abnormality in time, but the monitoring of the data collection process has not yet been realized
