Problems solved by technology

Therefore, the accuracy of infrared probe temperature measurement is not high.
In addition, the infrared probe cannot approach the heat source of the human body step by step, effectively judging the real intention of people walking, resulting in the abnormal opening of the infrared sensor automatic door

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the drawings and embodiments:

[0016] Such as figure 1 As shown, the present invention includes a door cushion layer 1, a double-layer hard board 2, a pressure-sensitive film 3, a Bluetooth transmitting module 4, a control processor 5, and a power source 6. The door cushion layer 1 is embedded with a double-layer hard Board 2. Three pressure-sensitive films 3 parallel to the door wall are sandwiched between the double-layer hard boards 2, and the side wall of one end of the door cushion layer 1 is equipped with a Bluetooth sending module 4, a control processor 5 and a power source 6;

[0017] Such as figure 2 As shown, the three pressure-sensitive films 3 are connected in series with corresponding resistors and then connected in parallel to the power supply 6 to form a piezoelectric module circuit. The output ends of the three pressure-sensitive films 3 are connected to the control processor 5 through...

Abstract

The invention discloses a pressure induction door mat used for controlling a door to be opened and closed. The pressure induction door mat comprises door mat cushions, double-layer hard boards, three pressure-sensitive thin films, a Bluetooth sending module, a control processor and a power supply; each double-layer hard board is embedded into the corresponding door mat cushion; the three pressure-sensitive thin films arranged side by side along a door wall are sandwiched between the double-layer hard boards; the Bluetooth sending module, the control processor and the power supply are arranged in the side wall of one side of the door mat cushions; after being separately connected with corresponding resistors in series, the three pressure-sensitive thin films are connected to the power supply in parallel; output ends of the three pressure-sensitive thin films are connected with the control processor through an A / D (analog / digital) converter; a signal is sent to a Bluetooth receiving module for automatic doors by the control processor through the Bluetooth sending module. The pressure induction door mat disclosed by the invention has the advantages that accurate control over the automatic doors is realized, and abnormal opening and closing of the automatic doors is avoided.

Description

Technical field [0001] The invention relates to a daily necessities, in particular to a pressure-sensitive door mat for controlling the opening and closing of a door. Background technique [0002] At present, automatic doors use pyroelectric infrared probes. After receiving the weak infrared signal from the human body, the pyroelectric infrared probe amplifies the infrared signal through an amplifier circuit, and then drives the DC relay to control the work of the bidirectional motor, so that people can approach the door. It opens automatically when the door is opened, and closes when the door is far away. [0003] Infrared probe temperature measurement is to estimate the temperature of an object by measuring infrared radiation. When the ambient temperature is close to the temperature of the human body, the detection sensitivity is significantly reduced, sometimes causing short-term failure. In addition, infrared radiation is not only a function of temperature, but also a function...
