Description

Technical Field

[0001] The present invention relates to the technical field of electronic identification, in particular to an electronic identification device for a construction site. Background Art

[0002] A construction site is a place where construction projects are being developed and civil engineering projects are being carried out. Its scope is often enclosed by fences, wire mesh or walls. In order to improve the safety of construction work, construction workers usually need to set up corresponding electronic identification equipment to electronically identify construction workers before entering the construction site, including face recognition, reflective clothing and helmet wearing, to prevent non-staff from entering the construction site and ensure that staff entering the construction site take corresponding safety protection measures.

[0003] At present, electronic identification devices used in construction sites are usually installed on the gates. Face recognition is performed by the electronic identification devices installed on the gates. However, such electronic identification devices are usually installed in a fixed manner and lack adjustment functions. Although recognition can be performed, there are problems of recognition limitations.

[0004] For example, (1) when the worker is too tall or too short, it is not convenient for identification work. The overall identification work requires the worker to cooperate with the identification instrument, and the identification instrument cannot cooperate according to the situation of different workers;

[0005] (2) It is not easy to identify the helmets on tall people. In addition, workers like to wear towels on their heads for sun protection. The presence of towels can easily cause errors in helmet identification, thereby affecting the accuracy of helmet identification. Summary of the invention

[0006] 1. Technical issues to be resolved

[0007] In view of the deficiencies in the prior art, the present invention provides an electronic identification device for construction sites. The upward and downward movement of the protective frame can drive the electronic identification group connected thereto to be adjusted up and down, thereby meeting the electronic identification work at different heights. Moreover, when the connecting frame moves to the top and its sliding rod moves to the horizontal groove at the top, the connecting frame as a whole will be in an inclined state, and then the protective frame can drive the electronic identification group to be tilted and adjusted, thereby facilitating the identification of workers wearing safety helmets. The height adjustment and angle adjustment are effectively linked and combined, and there is no need to set up an additional electric drive source for driving, thereby meeting the electronic identification work in different ranges. The functionality and comprehensiveness of the electronic equipment are improved, and the problem that the existing electronic identification equipment lacks the adjustment function, so that errors and recognition errors are prone to occur during face recognition and safety helmet wearing recognition, is solved.

The electronic identification group 5 adopts an instrument used in the prior art to identify the face, reflective clothing and helmet wearing of the staff, specifically including a camera;

[0050] Through the setting of the transmission component 9, the driving force for the up and down movement of the protective frame 4 is transmitted to the opening and closing component 7 and the protective component 8, so that the opening and closing component 7 automatically opens and closes the gate and the protective component 8 automatically performs the protective work, and the driving force for large-scale detection is fully utilized, which reduces the use of the electric driving source of the electronic identification equipment and improves the energy-saving and environmental protection performance of the equipment.

[0056] The transmission plate 91 is fixedly connected to the bottom of the sliding block 36 so that when the sliding block 36 moves up and down, the transmission plate 91 can be driven up and down synchronously. Through the up and down movement of the transmission plate 91, not only can the opening and closing component 7 be driven by the first transmission member to form an automatic gate opening operation, but also the protection component 8 can be driven by the second transmission member to form an automatic protection operation.

In conjunction with the continuous upward movement of the transmission plate 91, the driving gear 94 can be driven to rotate by the plurality of tooth blocks 95, and then the transmission rod 92 can be rotated, thereby fully utilizing the up and down scanning driving force without the need for an additional electric driving source for driving, thereby improving the energy saving and environmental protection of the electronic identification equipment.

[0063] Embodiment 2: Based on embodiment 1, the difference is that;

[0064] See attached Figure 5 The protection component 8 includes a movable shaft 81 rotatably connected to the inside of the control frame 2, one end of the movable shaft 81 extends to the front of the control frame 2, one end of the movable shaft 81 is fixedly connected to a blocking frame 82, and a torsion spring 83 is fixedly connected between the inner wall of the control frame 2 and the outer surface of the movable shaft 81;

[0065] The movable shaft 81 drives the blocking frame 82 to rotate 90 degrees, thereby protecting the identification area. It is not only convenient for the rear row to distance itself from the rear row personnel, improving its electronic identification effect, but also preventing the rear row personnel from interfering with the personnel in the identification area, and preventing the rear row personnel from following, making full use of the up and down scanning driving force, further improving the energy saving and environmental protection and identification performance of the electronic identification device;
