Problems solved by technology

[0003] However, the function of the electronic door plate in this invention patent is not yet perfect, and it is impossible to know and accurately judge whether the person near the electronic door plate is passing by or entering or leaving the door. In order to make up for this function, it is proposed to use the door status sensor to assist the electronic door plate Perfect its function
However, the result of using another door status sensor is to bring additional costs, such as equipment costs, installation costs, maintenance costs, etc.

Embodiment 1

[0049] Embodiment 1, with reference to attached Figure 1-3 , the present embodiment mainly introduces the hardware structural part of the electronic door plate of the present invention: an electronic door plate, including a house plate logo, a microcontroller module 1, a human body sensing module 2 for sensing people appearing inside and outside the door, and a distance measuring module , when the human body sensing module 2 is triggered, the microcontroller module 1 controls the ranging module to start working and measure the distance; the ranging module includes the first ranging module 3 and the second ranging module 4, and the first ranging module 3 probes the direction Facing the door, detecting the distance from the surface of the human body; the second ranging module 4 is arranged at the bottom of the main body of the electronic door plate and the direction of the probe faces inward, detecting the distance from the surface of the door. In this embodiment, the human bod...

Embodiment 2

[0055] Embodiment 2, with reference to attached Figure 4-9 , this embodiment mainly introduces the program flow part of the electronic door plate of the present invention, a method for detecting the height and direction of entry and exit of a person, comprising the following steps:

[0056] S101 acquires the trigger sensing signal of the pyroelectric infrared module;

[0057] S102 The current round of data collection starts, and the ultrasonic ranging module for detecting the distance from the surface of the human body and the laser ranging module for detecting the distance to the surface of the door are turned on;

[0058] S103 collects data every preset period to form a data stream, and collects data every 30 ms in this embodiment;

[0059] S104 judges whether the pyroelectric infrared module has no induction, the ultrasonic data is the ground background value, and the duration of the laser data without change meets the respective preset time at the same time, and if so, e...

Abstract

The invention relates to an electronic doorplate comprising a doorplate identifier, a microcontroller module, a human body sensing module and a distance measuring module. When the human body sensing module is triggered, the microcontroller module controls the distance measuring module to start working and measure distance. The human body sensing module can sense people inside and outside of a door. The distance measuring module comprises a first distance measuring module and a second distance measuring module. The first distance measuring module has a probe facing the direction outside the door, detects a distance to the surface of the human body. The second distance measuring module has a probe facing the direction inside the door and detects the distance to the surface of the door. The electronic doorplate can simultaneously detect the distance between the door and the surface of the human body and the distance between the door and the door surface, thereby determining whether a person passes by the door or enters the door on the basis of detecting the height of the person, and determining going direction of the person and the open / close state of the door.

Description

technical field [0001] The invention relates to the technical field of house personnel management, in particular to an electronic door plate and a method for detecting the height and direction of entry and exit of personnel. Background technique [0002] The applicant applied for an invention patent on 2016-11-02: an electronic door plate and house personnel management system, application number: 2016109494468, which mentioned an electronic door plate that can collect the height of people entering and leaving the door and their entry and exit The direction and time can be used to obtain the work and rest rules of the relevant personnel living in the house, so as to effectively manage the personnel. [0003] However, the function of the electronic door plate in this invention patent is not yet perfect, and it is impossible to know and accurately judge whether the person near the electronic door plate is passing by or entering or leaving the door. In order to make up for this ...
