[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0020] See also Figures 1 to 4In this embodiment, an infrared sensing intelligent access control device is provided, including a shell 1 and an infrared sensing probe 2. A control template 11 is installed on the front end surface of the shell 1, and the infrared sensing probe 2 is embedded on the front end surface of the shell 1. A card holder 12 is arranged on the outer end of the infrared sensing probe 2. A transparent hard film 13 is installed in the card holder 12 by a card connection. The transparent hard film 13 is closely attached to the front end surface of the infrared sensing probe 2. The left and right side walls of the shell 1 are symmetrically provided with fixing grooves. An alarm 14 is arranged in the fixing groove. The alarm 14 is electrically connected to the control template 11. An ultrasonic sensor 17 is arranged below the infrared sensing probe 2. When working, A PLC program is written in the control template 11 to control the operation of each device. When someone approaches, the ultrasonic sensor 17 senses a signal and controls the infrared sensing probe 2 to change from a standby state to a working state, thereby effectively saving power and avoiding overheating due to long-term work. Personnel can scan the infrared sensing probe 2 with a magnetic card to open the door. The surface of the infrared sensing probe 2 is protected from dust by a transparent hard film 13 to avoid poor recognition effect caused by scratching the surface of the infrared sensing probe 2 due to long-term work. When personnel make multiple recognition errors, an alarm 14 is used to sound an alarm to avoid theft.

[0021] The front end surface of the control template 11 is sequentially arranged with an infrared sensing module 18 , an ultrasonic sensing module 15 and an alarm module 16 .

[0022] A fan 19 is installed on the upper end surface of the shell 1, and an air inlet is installed at the bottom of the fan 19. A temperature sensor 21 is installed at the bottom of the shell 1. The temperature sensor 21 is electrically connected to the fan 19. When working, the temperature sensor 21 senses the internal temperature of the shell 1. When the temperature rises, the inside of the shell 1 is cooled by the fan 19 to prevent the internal circuit from burning.

[0023] The front end surface of the housing 1 is symmetrically embedded with an air outlet net 22 . When the fan 19 is started during operation, the wind is discharged through the air outlet net 22 .

[0024] A baffle 23 is arranged in front of the air outlet net 22, and the baffle 23 is rotatably connected to the front end face of the shell 1 through a pin shaft. The front end face of the shell 1 is symmetrically provided with circular grooves, and a limit spring 24 is installed in the circular groove. The other end of the limit spring 24 is installed on the rear end face of the baffle 23. When working, the baffle 23 seals and protects the air outlet net 22 to prevent external dust from entering. When the fan 19 is working, the internal wind force opens the baffle 23, so that the wind is discharged through the air outlet net 22.

[0025] The front end surface of the baffle 23 is installed with a first magnet 25, and the front end surface of the housing 1 is installed with an inclined frame 26. The inner end of the inclined frame 26 is made of magnetic material. When the fan 19 is working, the baffle 23 rotates and moves, and is attracted and fixed to the bottom of the inclined frame 26 by the first magnet 25, thereby limiting and fixing the baffle 23 to ensure stability during air outlet operation.

[0026] During specific operation, a PLC program is written in the control template 11 to control the operation of each device. When someone approaches, a signal is sensed by the ultrasonic sensor 17, and the infrared sensing probe 2 is controlled to change from standby state to working state, thereby effectively saving electricity and avoiding overheating due to long-term work. People can scan the infrared sensing probe 2 with a magnetic card to open the door. The surface of the infrared sensing probe 2 is protected from dust by a transparent hard film 13 to avoid poor recognition effect caused by scratching the surface of the infrared sensing probe 2 due to long-term work. When people make multiple recognition errors, a sound alarm is issued by the alarm 14 to avoid theft.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
