Abstract
The utility model provides a novel automatic door sensor comprising a brightness sensing module, an infrared LED display module and an image collection module, which are connected with a central processing unit (CPU). The brightness sensing module transmits environmental brightness information to the CPU; the CPU analyzes the brightness data and determines whether the infrared LED display module needs to be enabled; and then the CPU collects image data through the image collection module, extracts effective data through processing and generates a door-opening signal or maintains a normally-open state. The novel automatic door sensor integrally improves the safety and flexibility of a whole automatic sensing door.
Description
[technical field]
The utility model relates to a kind of automatically-controlled door sensor structure, particularly a kind of sensor structure of responding to automatically-controlled door.
[background technology]
In induction automatically-controlled door field, inductor is serving as most crucial role in control system, the development of modern science and technology, the function of inductor has been proposed to more requirement, required the inductor can perception, also should possess recognition capability simultaneously, that is, can as the eyes, have " eyesight ".
In the prior art, the inductor that induction door is used has two large classes: one, infrared inductor; Two, microwave sensor.Wherein infrared inductor has two kinds: active type infrared induction device, passive type infrared inductor.Microwave sensor, utilizes Doppler's principle to do, and it can only detect mobile object.Active type infrared induction device, has certain requirement to installation environment, because it can be subject to the interference of thermal source, light source etc.Passive type infrared inductor, penetration power is poor, and the infrared radiation of human body is easily blocked, and when environment temperature and human body temperature approach, sensitivity meeting obviously declines.Therefore, above-described existing various inductors, in fact all cannot really allow the ability of sensing apparatus standby " eyes ".
In existing patent documentation, about the improvement patent of automatically-controlled door inductor, have the utility model patent of earlier application, proposed camera to be contained in the technical scheme on inductor, its architectural feature just allows camera participate in data acquisition and then sends data to outer DVR of joining.But structurally, do not allow the image acquisition units in inductor be connected with control system, and become a functional organization of whole induction automatic door control system, do not have and allow sensing apparatus for eyes, be i.e. the technical characterictic of " eyesight ".
[summary of the invention]
In order to solve the problems of the technologies described above, fundamental purpose of the present utility model will allow induction door clearly know for Whom and open the door exactly, and it clearly sees people or object by image collecting module, while arriving induction region, gives one of induction door " enabling signal ".In the time of in object rests on induction door moving region, allow " enabling signal " often to have, allow like this induction door keep door opening state, preventing from closing the door clips to people and causes security incident.
The utility model is achieved through the following technical solutions:
A kind of automatically-controlled door inductor of the utility model, comprise brightness impression module, central processing unit (CPU), infrared LED display module, image capture module, driver module is electrically connected with power supply processing module respectively, it is characterized in that: also comprise brightness impression module, infrared LED display module, image capture module is connected with central processing unit (CPU), through brightness impression module, ambient brightness information is passed to " CPU ", " CPU " analyzes brightness data, judge whether to open infrared LED display module, central processing unit (CPU) draws after image analysis data by image capture module, drive driver module, pass on the instruction of " opening the door " or " often opening " to induction door control system.
Wherein, described image capture module can comprise a camera or image collection chip.
Wherein, described driver module comprises a relay
Wherein, described instruction comprises enabling signal
Wherein, described instruction also comprises and often opens signal

[embodiment]
Below in conjunction with accompanying drawing, further illustrate structure of the present utility model, advantage and object.
Fig. 1 is the location diagram of inductor 10 described in the utility model and induction door controller 18
As described in Figure 1, the hub location of inductor 10 in whole induction door control system, its effect is equivalent to the sense organ of whole induction door controller 18.
Fig. 2 is the functional block diagram of the utility model novel inductor specific embodiment
As shown in Figure 2, the utility model comprises brightness impression module, central processing unit (CPU), infrared LED display module, image capture module is electrically connected with power supply processing module respectively, brightness impression module is connected with central processing unit (CPU), also comprise that a driver module and infrared LED display module are connected with central processing unit (CPU), image capture module is connected with central processing unit (CPU), through brightness impression module, ambient brightness information is passed to central processing unit " CPU ", central processing unit " CPU " is analyzed brightness data, judge whether to open infrared LED display module, central processing unit (CPU) draws after image analysis data by image capture module, drive driver module, move instruction is to controller, wherein, instruction comprises " opening the door " signal and " often opening " signal.
Fig. 3 is the electrical structure schematic diagram of the concrete embodiment of the utility model automatically-controlled door inductor
As shown in Figure 3, in specific embodiments, described power supply processing module 11 is obtained 12V/24V power supply by dispatch from foreign news agency.
Described image capture module can comprise a camera 131, also can comprise an image collection chip (the present embodiment wouldn't illustrate).Described driver module can comprise a relay 161.
Wherein, described image capture module, if adopt image collection chip while specifically implementing, does not limit for chip model, imaging pixel etc.As direct employing camera 131, camera lens model, line number,
Pixels etc. do not limit.
As shown in Figure 3, the utility model comprises power supply processing module 11, brightness impression device 121, camera 131, central processing unit (CPU), infrared LED display module 15, relay 161 and induction door controller 18.
Wherein, camera 131 is connected with power supply processing module 11, and camera 131 is connected with central processing unit (CPU).
First, by brightness impression device 121, ambient brightness information is passed to central processing unit (CPU), central processing unit (CPU) is analyzed brightness data accordingly, judges whether to open infrared LED display module 15.Then, by camera 131 acquisition of image data, through central processing unit (CPU), carry out view data processing, extract active data, and analyze, finally judge whether to drive relay 161, pass on instruction to controller 18.As described in Figure 2, the instruction in Fig. 3 comprises enabling signal and Chang Kai signal.
In specific embodiments, described " opening the door " signal, refers to the of short duration action of opening the door, and after people or object leave, a door body closes automatically; Described " often opening " signal, refers to door opening state according to system requirements, and the people or the object that for inductor, perceive continue for some time door opening state.Like this, just avoided induction door to open the door too quickly closing the door crushing people.
