The remote control unit is used to drive the gate system to operate, and the monitoring system is used to monitor the opening and closing status of the gate system. The gate system includes:

[0025] A door pile 1, wherein a plurality of door piles 1 are arranged horizontally and centrally symmetrically, a closed door 4 is slidably interlaced and connected in the middle of the door pile 1, and a door opening motor 2 for controlling the sliding of the closed door 4 is arranged at the bottom of the door pile 1;

[0026] Specifically, a communication control module and a drive module are provided inside the door opening motor 2. The communication control module is used to communicate with the remote control unit, and the communication control module is used to control the on and off of the drive module. The drive module is used to drive the output end of the door opening motor 2.

[0027] It should be noted that the remote control unit is usually set as a remote controller, which is internally provided with a signal transceiver. After sending a drive control instruction to the communication control module of the door opening motor 2, the communication control module performs on-off control of the drive module circuit, so that the output end of the door opening motor 2 can be rotated and controlled. The remote control is mainly used to operate the door opening and closing and stopping of the door opener. There are four buttons on the controller: door opening control button, door closing control button, stop button and lock button. The function range of the remote control is ≤200m;

[0028] In this solution, the door opening motor 2 is composed of a high-strength aluminum alloy housing, a high-quality single-phase motor, an overrunning friction clutch, a worm gear reducer and a gear clutch. The working parameters of the door opening motor 2 are voltage 220V / 50HZAC, motor power 550W, starting power supply 3A, and motor speed 12m / min.

[0029] Specifically, the monitoring system includes a support pile 6 , and a camera 601 and an antenna are arranged on the top of the support pile 6 . The camera 601 is used to photograph the opening and closing status of the closed door 4 , and the antenna is used to transmit the photographing information of the camera 601 .

[0030] It should be noted that the camera 601 used in this solution can be connected to the network and the mobile phone through an antenna, so that the mobile phone or iPad can visually control the door.

[0031] Specifically, a tooth plate 402 is provided at the bottom end of the closed door 4 , and a driving gear 201 is provided at the output end of the door opening motor 2 , and the outer wall of the driving gear 201 is meshed with the tooth side of the tooth plate 402 .

[0032] Specifically, a placement groove 101 is provided on the top inner wall where the door pile 1 and the closed door 4 are inserted, a support slide groove 102 is provided in the middle of the door pile 1 and through the back, a limiting slider 401 is fixedly connected to the top of the closed door 4, and the top of the limiting slider 401 is slidably inserted and connected in the placement groove 101. Through the cooperation between the limiting slider 401 and the placement groove 101, the closed door 4 can slide stably in the horizontal direction. At the same time, sufficient space for the limiting slider 401 to move upward is reserved at the top of the placement groove 101 to realize the lifting adjustment of the closed door 4, and a supporting slide plate 403 is fixedly connected to the back of the closed door 4, and the supporting slide plate 403 is slidably inserted and connected in the supporting slide groove 102.

[0033] Furthermore, a lifting mechanism for lifting and supporting the slide plate 403 is provided on the back of the gate pile 1, and the lifting mechanism includes:

[0034] The control lever 7 is horizontally and longitudinally rotated to be inserted into the back of the gate pile 1. A cam plate 701 is sleeved on the middle of the control lever 7. The cam plate 701 adjusts the lifting height of the support slide plate 403 through the two ends at the farthest distance.

[0035] The control knob 702 is sleeved on one end of the back of the control rod 7, and a locking plug 703 is fixedly connected to the side of the front of the control knob 702. Two positioning holes 103 are vertically symmetrically provided in the middle of the back of the door pile 1, and the locking plug 703 is slidably inserted into and connected with one of the positioning holes 103.

[0036] Furthermore, the inner walls of the top and bottom ends of the control knob 702 and the control rod 7 are provided with limiting grooves, and the top and bottom ends of the control rod 7 are fixedly connected with blocking sliders 704, and the blocking slider 704 is slidably inserted and connected in the limiting groove, and a supporting spring 705 is arranged in the limiting groove.

[0037] It should be noted that the lifting mechanism is provided so that when the gate control power is out or the gate equipment fails, and the remote control of the gate opening / closing by remote control or mobile phone / IPad fails, the lifting mechanism will change the remote control opening / closing function of the gate to manual opening and closing of the gate.

[0038] During the actual operation process, when it is necessary to switch to the manual operation mode, it is necessary to first pull the control knob 702 in the direction away from the door pile 1 until the locking block 703 is moved out of the positioning hole 103, and then rotate the control knob 702 to 180°. At this time, the control knob 702 drives the control rod 7 through the blocking slider 704 to make the cam plate 701 rotate 180°, so that the end of the cam plate 701 farthest from the control rod 7 will be vertically upward and lift the support slide plate 403. At this time, the engagement between the driving gear 201 and the tooth plate 402 is disconnected, and the closed door 4 can be slid open and closed.

[0039] An indicator 3, which is arranged on the top of the door pile 1 and is used to indicate the open or closed state of the closed door 4;

[0040] It should be noted that when the gate is closed, the indicator 3 displays a red light, and the door opener needs to use the remote control to open the two gates to a safe position within ≤200m, and the gate indicator mechanism displays a white light.
