(III) cleaning Process
In-process of 1 adjustment position of above-mentioned wireless camera, the horizon bar reciprocates, horizon bar and piston rod 5 are articulated through connecting rod 7, piston rod 5 makes progress or downstream in step, because the round platform form of dead lever 6 for the inversion of big-end-up, piston rod 5 is along the bar hole motion in-process, piston rod 5 exposes the partial length increase of water storage box or reduces, connecting rod 7 moves right or left simultaneously, thereby piston rod 5 pulls or promotes piston 4, and then piston 4 compresses right water storage box or left water storage box 2, if piston 4 compresses left water storage box 2, then 2 water pressure increase of left water storage box, pressure valve 9 is opened, the water of left water storage box 2 passes through shower nozzle 8, spray to wireless camera 1 on.
In the piston rod 5 along bar hole motion process, because connecting rod 7 moves to the right or left, connecting rod 7 drives horizontal pole 11 and slider 12 synchronous right or left movement, this moment, pulley 13 moves along the spout on slider 12, thereby stretch or compress first spring 15 through vertical pole 14, vertical pole 14 drives right-angle pole 16 and moves up or move down simultaneously, consequently, the cleaning brush is synchronous upwards or move down, the cleaning brush contacts with wireless camera 1, thereby the cleaning brush cleans the spot of wireless camera 1, because the cleaning brush is formed by Polycarbonate (PC) material preparation, the PC material has high transparency and tasteless odorless, harmless to the human body, accord with the characteristics of health and safety, so the accuracy influence that the cleaning brush discerned the people face to wireless camera 1 is little.
(IV) identification Process
When the wireless camera 1 is over against the face, the face recognition technology is used for recognizing the face, if the face appearing in the video area is successfully matched with the face stored in a face library in advance, namely the face recognition is successful, a trigger signal after the successful matching is sent to a gateway through an internal wireless network, a control command is sent to a specified routing node or a terminal node through a Zigbee network, a corresponding access control device is driven, and the access control is opened; if the face recognition fails, a warning prompt tone is sent out at the monitoring end according to the trigger signal which is unsuccessfully matched, monitoring personnel sense that external personnel visit according to the prompt tone, and whether the access control is opened for the monitoring personnel can be judged through remote conversation with the monitoring personnel through a 4G or WIFI network or according to a monitoring picture. If the person can enter the system, the entrance guard is opened, and if the person is found to be suspicious, the person can be set up with a defense in advance.
Wherein, wireless camera 1 downstream in-process, under the effect of compressed third spring 3, piston 4 level moves right for 5 spherical cap ends of piston rod offset with the bar hole all the time.
Example two
The security access control system of the second embodiment only lies in with the security access control system difference of implementing the first: the welding of retaining box top has the case of intaking that the opening faces up, carries out bottom of the case portion left side and is equipped with the delivery port, and the delivery port has set firmly the filter screen, and the filter screen is used for filtering the impurity of rainwater, makes impurity unable entering shower nozzle 8 to lead to shower nozzle 8 to block up, the left side of retaining box is equipped with the water inlet, and the water inlet just to just through the pipe connection with the delivery port, and the water inlet articulates there is the baffle, and the baffle is located 2 inboards of left retaining box, and the baffle is used for sealing.
The specific implementation process is as follows:
when raining, rainwater is stored through the water inlet tank, when clear water in the left water storage tank 2 is reduced, namely the left water storage tank 2 is not filled with clear water, the water inlet is opposite to the water outlet, the partition plate is flushed by the clear water under the action of gravity of the water, the torsion spring is bent, the water in the water inlet tank enters the left water storage tank 2, and after water supplement of the left water storage tank 2 is completed, the partition plate resets under the action of the torsion spring, namely the water inlet is sealed by the partition plate.
