Abstract

According to the underground pipe gallery personnel positioning method, the characteristic that the fisheye lens has a wide viewing angle is utilized, and the fisheye lens and the camera sets arrangedat intervals are driven in cooperation with the rotation selecting mechanism, so that the number of shooting dead corners is small, all corners in an underground pipe gallery can be clearly shot, andthe overall positioning accuracy is improved. Moreover, the face recognition is used for replacing each person for positioning, and the body contour is used for the person recognition, so as to improve the overall recognition accuracy. Besides, in order to avoid the situation that the violation alarm acts continuously and interferes with field personnel due to wrong identification of the processor, the personnel can also carry out verification through the identity verification unit, and after identity verification is passed, the violation alarm stops acting.

Description

technical field

[0001] The invention relates to the technical field of comprehensive utility corridors, in particular to a personnel positioning method for underground utility corridors. Background technique

[0002] The underground pipe corridor is a major project to improve the overall carrying capacity of the city and meet the needs of the people's livelihood. It is mainly to build a space under the road to centrally manage and set up drinking water pipes, cables, communication cables, gas pipes, sewage pipes and other pipelines. In the future, the maintenance and installation of various pipelines will become more organized and convenient, which will greatly help to improve the overall image of the city.

[0003] Since the setting of the underground pipe gallery must be arranged in accordance with the above-ground buildings, it has the characteristics of narrow, long and rugged. Therefore, when personnel work in the underground pipe gallery, how to effectively grasp the p...

Embodiment approach

[0089] (1) First of all, due to the large area of ​​the underground pipe gallery, it is very likely that personnel will get lost when working in the underground pipe gallery. In order to effectively avoid problems such as getting lost, the present invention uses the aforementioned positioning function and cooperates with indicating signs to guide Insiders leave. For this reason, the creation of the present invention can be further implemented as follows: a plurality of electronic indication signs 5 are arranged at intervals in the underground corridor, and when the personnel send a lost message through the communication unit 6, the lost message preferably contains the purpose According to the lost information and the personnel positioning data, the processor 2 controls the action of each electronic route indication sign 5, such as controlling the action of the electronic route indication sign 5 between the personnel positioning place and the destination, so as to The person is...
