The present invention relates to a smart multifunctional safety induction electric access control system, in particular to an electric access control technology that can be set up with a pedal-type sensing structure to ensure and improve the safety of users when entering and exiting an electric door.

According to the general store, the structure of the door is mostly an inductive electric door that is convenient for users to enter and exit. The specific structure of the conventional induction type electric door is shown in Figure 9. A human body infrared sensor 100 is installed on the inside and outside of the doorway. When a user stands in the sensing range near the inside and outside of the doorway, the human body infrared sensor The device 100 generates a human body sensing signal due to the human body and transmits it to the control unit. The control unit interprets it and outputs a door-opening control signal for driving the electric door 10 to open. After a preset period of time, the control unit determines whether it receives If there is a human body sensing signal, it will continue to output the door opening control signal; if not, it will output the door closing control signal for driving the electric door 10 to close.

Although the conventional induction electric door can achieve the function of automatic induction opening and closing of the electric door; however, most of the sensors on the market currently use infrared human sensors, so that there will be signal sensing dead corners, and it is easy to be interfered by signals. Sensing errors occur. In addition, the elderly and people with mobility impairments usually enter and exit the induction door because the door is opened for too short a time, which causes the closed door to be pinched; or collide with the electric door. Cause injury. Secondly, the conventional induction electric door does not have the function setting of the second sensing mechanism, so when moving things in and out of the electric induction door, often because the door is not open for long enough, the sensor must be turned off or used. The door piece is jammed, so that the electric induction door can be smoothly entered and exited. Not only that, when the general user enters and exits a convenience store, if the cash register in the store is next to the door, when the checkout and queue are crowded, it is easy to open and close the electric induction door, thus speeding up the damage of the electric door Therefore, how to develop an electric induction access control technology with a pedal-type sensing structure to ensure and improve the safety of the user when entering and exiting the electric door has become a technical issue that the related technical field is urgently trying to solve and challenge.
