The technical scheme of the utility model is explained in detail below with the attached drawings:

as shown in figure 1, the face recognition device for the time-interval one-way traffic gate comprises a recognition module 1, wherein a camera is arranged on the recognition module 1, and a display screen is further arranged and used for shooting a face image and displaying prompt information. The shot image is transmitted to a background server through a network, recognition matching is completed by using a face recognition algorithm, and the result is transmitted back to a gate end to control the gate to be opened and closed. The face recognition process and the gate control are common knowledge in the field, are not innovative in the patent, and are not described in detail.

The difference of this equipment lies in: as shown in fig. 1 and 2, the gate machine further comprises a support rod 2 mounted on the body 3 of the gate machine in a rotating connection mode, and a bearing can be arranged at the rotating connection position to reduce friction resistance or can be matched with a sliding shaft hole. The identification module 1 is mounted on a support bar 2.

The equipment also comprises a rotary driving device for driving the supporting rod 2 to rotate and a control device for controlling the action of the rotary driving device.

In this embodiment, the rotation driving device is an air valve actuator 4 with a steering angle of 90 degrees, and an output shaft of the rotation driving device drives the support rod 2 to rotate through a transmission mechanism. The air valve actuator 4 is relatively common in the market, and is provided with a zero line connecting end 4-1, a first live line connecting end 4-2 and a second live line connecting end 4-3 as shown in fig. 3. When the first live wire connecting end 4-2 is electrified, the actuator rotates 90 degrees in the forward direction, and when the second live wire connecting end 4-3 is electrified, the actuator rotates 90 degrees in the reverse direction.

As shown in fig. 2, the transmission mechanism includes a first gear 5 mounted on the output shaft of the damper actuator 4 and a second gear 6 connected to the support rod 2, the first gear 5 is engaged with the second gear 6, and the number of teeth of the first gear 5 is twice that of the second gear 6.
