The face recognition unit 110 may be a terminal device with a camera, and may be connected to the face database, and is configured to match with resources in the face database after recognizing a face, and if matching is successful, determine that the passer has a passing right.
The position of the main control unit 150 in fig. 1 may be a virtual position, and since it may be a microcontroller or the like disposed inside the express door, it may be disposed at a corresponding main control board or other position. The main control unit 150 may be a processor having a memory capability and an arithmetic capability, and may also be a microcontroller or the like disposed on the main control circuit board. The main control unit can be connected with other units, performs corresponding information processing, and sends out a control instruction for response.
The gate unit 120 is connected to the main control unit 150, and configured to turn on or turn off a gate according to a control signal sent by the main control unit 150.
Specifically, the main control unit 150 may control the gate through the received control signal, and if a low level control signal is received, it is determined that the gate is kept in a door closing state, and if a high level control signal is received, the gate is controlled to be opened, and at this time, a passerby may be allowed to pass through.
Light curtain correlation is the main mode that the fast door that leads to carries out state detection in the passageway, if need improve the interior detection precision of passageway, improve the precision that the trail detected, then just need increase the position of light curtain correlation, two sets of light curtain correlation about well high-end floodgate machine can set up usually, every group probably has 20 to and above infrared position, the principle of infrared correlation is the transmission and the receipt of light, floodgate machine passageway side-mounting infrared emission lamp, the infrared receiving lamp is installed to the opposite side of passageway, the infrared light of emission lamp transmission shines and receives the lamp pearl, receive lamp pearl output high level and give control chip, shelter from infrared light when personnel are current, after the light can not be received to the receiving lamp, output low level gives control chip, control chip passes through the level height, can know whether there is personnel in the passageway at current.
However, the current problem is that the application environment of the express door is complex, and may be an indoor environment or an outdoor door opening, and after the number of infrared points is increased, it is difficult to avoid the occurrence of a probabilistic fault at some points during the use process. The abnormal operation of the quick-acting door can be caused by the fault of the device, and the alarm can be generated due to the environmental factors of the light refraction, the abnormal irradiation and the like caused by raindrops. The main control unit (which can be a main control chip) mistakenly judges that a person is in the passage, the gate machine can give an alarm immediately, and the action of switching the gate machine is avoided, so that the passing efficiency is seriously influenced. Especially, in the environments of office buildings, dormitories and the like at morning peaks or evening peaks, serious people congestion can be caused, and the user experience is very poor.
The light curtain opposite-emitting unit 130 includes an emitting end and a receiving end, where the emitting end and the receiving end are respectively disposed on two sides of the fast passing door and have corresponding numbers, for example, there are 20 emitting ends and 20 receiving ends, or there are 40 emitting ends and 40 receiving ends. The more the number of the transmitting ends and the receiving ends is, the more accurate the judgment of the passing person is.
The main control unit 150 is connected to the light curtain correlation unit 130, and is further configured to identify whether a shielding signal exists;
the object detection unit 160 is configured to perform object detection under the condition that the light curtain correlation unit 130 detects that the shielding signal exists.
The main control unit 150 is configured to determine whether an obstructing object exists according to an object detection result.
Under the condition that the light curtain correlation unit 130 detects that the shielding signal exists, the detection process of the object detection unit can be added to determine whether the shielding object exists. If the pedestrian exists, the pedestrian can be determined to exist, the gate machine can not be opened, and the pedestrian in front can be prevented from being impacted and injured in the process of opening the gate.
In this embodiment, optionally, the main control unit 150 is further configured to:
and controlling the gate to normally work under the condition that the object detection unit 160 determines that no shielding object exists.
If the light curtain correlation unit 130 detects that there is a blocking signal and it is determined that there is no blocking object in the object detection unit 160, it may be determined that there is an abnormality in the transmitting end or the receiving end of the light curtain correlation unit 130, and it may be determined that the gate may normally operate, such as being turned on or turned off, by ignoring the blocking signal. Through the arrangement, the situation that the fast-passing door cannot work correctly due to the abnormal work of the light curtain opposite-emitting unit can be avoided.
In this scheme, optionally, the object detection unit 160 adopts an ultrasonic radar detection device or a millimeter wave radar detection device.
The working principle of the ultrasonic radar is that the distance is measured and calculated by the time difference between the time when the ultrasonic wave is sent out by the ultrasonic wave transmitting device and the time when the ultrasonic wave is received by the receiver. At present, the working frequency of the common probe is three types of 40kHz,48kHz and 58 kHz. Generally, the higher the frequency, the higher the sensitivity, but the smaller the detection angle in the horizontal and vertical directions, so a 40kHz probe is generally used. The ultrasonic radar is waterproof and dustproof, and even if a small amount of silt is shielded, the influence is avoided. The detection range is between 0.1 and 3 meters.
The millimeter wave radar operates in the millimeter wave band. Usually, the millimeter wave refers to the frequency band of 30 to 300GHz (the wavelength is 1 to 10 mm). The wavelength of the millimeter wave is between the centimeter wave and the light wave, so the millimeter wave has the advantages of microwave guidance and photoelectric guidance. Compared with the centimeter wave seeker, the millimeter wave seeker has the characteristics of small volume, light weight and high spatial resolution. Compared with optical probes such as infrared, laser and television, the millimeter wave probe has strong capability of penetrating fog, smoke and dust. In addition, the anti-interference and anti-stealth capabilities of the millimeter wave seeker are also superior to those of other microwave seekers.
In this embodiment, optionally, the object detecting unit 160 is disposed at a height between 30 cm and 80 cm from the ground.
The gate can detect pedestrians with various heights only at the height, and can be arranged on the inner sides of the frames on the two sides of the gate only without independently arranging a hardware structure, so that the installation is simplified.
The alarm unit 140 is configured to perform gate alarm when the main control unit determines that a blocking object exists.
It can be understood that the alarm unit can give an alarm in the forms of sound, light and the like, so that the working personnel can find the existing abnormal conditions in time and properly handle the abnormal conditions, and the passing barriers to the pedestrians are avoided.

and if the fact that the movement of the barrier between the transmitting end and the receiving end of the light curtain correlation unit meets the passing rule of the pedestrian is detected, determining that the detected person passes through.
The pedestrian passing rule can be the number of the shielded light paths or the moving speed of the shielding signal, and if the position of each light path is known, the speed of the pedestrian can be determined according to the time of shielding the light paths by shielding objects. If the light path is blocked by a certain amount and/or the moving speed meets a preset range, the existence of the passer is determined, and the passing time of the passer can be determined. And can determine when the passers-by have all passed the gate location.
On the basis of the above technical solutions, optionally, the main control unit 150 is further configured to:
in case the object detection unit 160 determines that there is no obstructing object, the failing light curtain point location is determined.
For example, in the case where there is a low level signal that is always a level signal transmitted from one or more receiving terminals, it is possible to determine that the transmitting terminal or the receiving terminal at that position is failed, and determine the potential of the failure. Through the arrangement, repair information can be generated according to the failed potential, so that a maintenance object can be determined quickly and accurately according to the repair information.
On the basis of the above technical solution, optionally, the main control unit 150 is further configured to:
and reporting the failure light curtain point location to a background.

As shown in fig. 3, after the face recognition terminal detects a face, permission determination is performed, if no permission exists, an unregistered gate is prompted not to open a door, if permission exists, determination is performed in a gate channel, and if light curtain correlation is continuously shielded, whether an object exists in a true channel is determined through a channel radar. If the radar judges that the object exists, the gate gives an alarm, the intrusion is considered, and if the radar judges that the object does not exist, the light curtain is considered to be triggered by the opposite emission error or damaged.
Specifically, when the main control unit recognizes that the light curtain is blocked, the actual time length of the light curtain being blocked is about 10ms, so that the main control unit recognizes that the blocking is actually a short-time continuous blocking. This has the advantage that false identifications caused by problems with beam emission or momentary occlusion of other objects can be avoided.
At the moment, the shielded point position is shielded, the gate normally opens the door, if the light curtain correlation is not shielded, the gate normally opens the door as well, after the door is opened, the light curtain correlation is used for judging the passing personnel, after the light curtain is shielded in sequence, the gate is closed when the personnel pass, and the passing is finished; if the light curtain is not shielded all the time after the door is opened, judging that the person brushes the face and does not pass after a certain time, and closing the door if the door is closed overtime; if the light curtain is continuously shielded, the personnel are considered not to come out after entering the channel, and overtime alarm is carried out after a certain time.
Through the mutual cooperation between two sets of equipment, effectively guaranteed precision and validity that the floodgate machine judged, reduce false triggering and wrong report police, improve the reliability of using.
