Description
Technical field
The utility model belongs to the electronic communication field, relates to a kind of safe examination system, is specifically related to a kind of subway safety check row bag monitoring synchro system.
Background technology
The subway volume of the flow of passengers is big, and personnel's row bag is complicated, and especially in peak time, two kinds of situation can appear in the subway safe examination system:
1, the numerous stacks of row bag are difficult for the actual row bag of identification when the safety check image is found suspicious contraband or dangerous material.
2, security check passage exit handbag is hasty, wrong taking or intentional theft phenomenon occur.
Two types of existing safe examination system technical points: 1) adopt safety check row bag image and monitoring image to store separately, row bag safety check image is stored in the screening machine, and monitoring image is stored in the DVR.Because screening machine and DVR time are also asynchronous, therefore two kinds of images are not strict synchronism, and are relatively more inconvenient on the enquiry of historical data yet.2) adopt video frequency collection card, the rig camera image is captured or gathered in real time, be stored in simultaneously in the industrial computer hard disk of screening machine with safety check row bag image.Increased the workload of former screening machine software systems so greatly; Cause destabilizing factor, for example: if candid photograph can be missed some monitoring details, if real-time acquisition monitoring image; Hard disk should be stored a large amount of safety check row bag images; Store the real-time monitor video data of greater amount again, must realize simultaneously covering and wipe renewal, existing hard-disk capacity commonly used and performance are difficult to satisfy the demand.
The utility model content
The shortcoming of prior art in view of the above, the purpose of the utility model are to provide a kind of subway safety check row bag monitoring synchro system, show with the monitoring image synchronization of data and store in order to realize row bag view data.
For realizing above-mentioned purpose and other relevant purposes, the utility model provides a kind of subway safety check row bag monitoring synchro system.
A kind of subway safety check row bag monitoring synchro system, said subway safety check row bag monitoring synchro system comprises: rig camera, screening machine, VGA transducer, AV change BNC connector, screening machine display, DVR; Said rig camera is arranged at the channel entrance and the outlet of screening machine; Said rig camera is communicated by letter with said DVR through the BNC video line and is linked to each other; The VGA output of the industrial computer video card of said screening machine links to each other with the VGA input of said VGA transducer, and the AV output of said VGA transducer changes BNC connector with said AV and links to each other; Said AV commentaries on classics BNC connector is communicated by letter with DVR through the BNC line and is linked to each other; The VGA output of said VGA transducer is communicated by letter with the screening machine display and is linked to each other.
As a kind of preferred version of the utility model, said subway safety check row bag monitoring synchro system also comprises a display, and said display is communicated by letter with said DVR and linked to each other.
As the another kind of preferred version of the utility model, said subway safety check row bag monitoring synchro system also comprises a monitoring support, and said monitoring stent support connects said rig camera.
As stated, the described subway safety check of the utility model row bag monitoring synchro system has following beneficial effect:
1, convenient accurate data query.When searching historical data, can inquire historical monitoring image and synchronous safety check image simultaneously, all scenario of entire field is all had record, greatly make things convenient for inquiry in DVR the inside; Like the finer correction data of checking of need, can search more accurate row bag safety check original image according to the time;
2, system stability.After adopting the monitoring of the described subway safety check of the utility model row bag to be synchronously, original safe examination system did not change, and the DVR storage system is quite ripe, can realize the storage update of mass data.
