Embodiment 1

[0080] Embodiment 1: Among the bayonet capture devices in the group, there are devices without vehicle passing records.

[0081] First judge whether the bayonet capture device without vehicle passing record has other bayonet capture devices in the same group. Enter the next step of judgment;

[0082] Judging whether other bayonet capture devices in the same group have passing vehicle information, if there is none, then determine that the group of devices is a missing bayonet capture device, otherwise enter the next step of judgment;

[0083] If other bayonet capture devices in the same group have passing vehicle information, judge whether the passing information of other bayonet capture devices contains the vehicle license plate (the license plate corresponding to DevA) where the track recording device is located, and if not, judge that the group of devices is missing The bayonet capture device.

[0084] It is easy to understand that if the group of bayonet capture devices d...

Embodiment 2

[0087] Embodiment 2. All bayonet capture devices in the group of bayonet capture devices have vehicle passing records.

[0088] If the group of bayonet capture devices has passing vehicle information, and there is no passing record in the passing vehicle information that is consistent with the license plate of the vehicle where the track recording device is located, then it is judged that the group of devices is a missing bayonet capture device.

[0089] It should be noted that there is certain uncertainty in the recognition of the license plate by the passing record, that is, there may be a wrong license plate recognition. Whether the recognition of the license plate is accurate is usually judged according to the confidence level. If the confidence level is high, the judgment is accurate, and if the confidence level is low, there may be misrecognition.

[0090] Therefore, the method of the embodiment also includes the steps when judging the status category of the group of mon...

Abstract

The invention discloses an operation detection method and device for front-end monitoring device based on track information. The method comprises that track information of a track recording device in a specific statistic period is extracted from track information reported by the track recording device on a vehicle; effective front-end monitoring devices in the specific range in the surrounding of the track corresponding to the extracted track information is searched; the effective front-end monitoring devices are grouped according the specific range, and vehicle passing records of each group of the front-end monitoring devices in the vehicle passing period are searched from the track recording devices; and the group of front-end monitoring device is determined. The operation detection device comprises a track information extraction module, a front-end device searching module, a grouping module, a vehicle passing record query module and a determination module. According to the method and device, the front-end monitoring device with faults can be discovered by a user conveniently, so that maintenance is carried out timely, and reliable operation of the device is ensured.

Description

technical field [0001] The invention belongs to the technical field of traffic monitoring, and in particular relates to a method and a device for performing operation and maintenance detection of monitoring front-end equipment based on trajectory information. Background technique [0002] The bayonet electric police system in traffic management adopts advanced photoelectric technology, image processing technology, and pattern recognition technology to take pictures of every passing car, and automatically recognize the license plate of the vehicle. Information data are stored in the server database. [0003] The use of the bayonet electric police system is very meaningful for road construction. It can quickly capture accident vehicles, illegal vehicles, blacklisted vehicles, etc., and conduct uninterrupted automatic monitoring of the composition of road vehicles, traffic distribution, and violations throughout the year. Records, providing important basic and operational data...
