The first dual microwave module 1110 is configured to emit an electromagnetic wave to a first sensing region, and simultaneously receive an electromagnetic wave reflected from the first sensing region, and respectively output a first doppler signal and a second doppler signal according to the emitted electromagnetic wave and the reflected electromagnetic wave, the first amplifier 1111 and the first filter 1113 respectively perform signal amplification processing and filtering processing on the first doppler signal, the second amplifier 1112 and the second filter 1114 respectively perform signal amplification processing and filtering processing on the second doppler signal, and the first single chip 1115 receives the first doppler signal and the second doppler signal respectively subjected to signal amplification processing and filtering processing, and outputs a first sensing signal according to the first doppler signal and the second doppler signal.

Specifically, the first microwave sensor 111 of the present embodiment is installed outside the door of the automatic door 1, and the first dual microwave module 1110 has a first transmitting antenna, a first receiving antenna, a first mixer and a second mixer, wherein the first mixer and the second mixer are electrically connected to the first amplifier 111 and the second amplifier 1112, respectively, when the first microwave sensor 111 is installed, a first sensing region is formed outside the door, the first transmitting antenna and the first receiving antenna sense the characteristics of the operation signal in the first sensing region, the first transmitting antenna can continuously transmit an electromagnetic wave to radiate the first sensing region, and simultaneously, the first receiving antenna receives the reflected electromagnetic wave reflected by the first sensing region.

In other words, when the moving direction of the moving object in the first sensing region is away from the door 1, the phase of the first doppler signal output by the first microwave sensor 111 is advanced by 90 ° with respect to the phase of the second doppler signal, and when the moving direction of the first sensing region is close to the door 1, the phase of the first doppler signal output by the first microwave sensor 111 is delayed by 90 ° with respect to the phase of the second doppler signal.

In this embodiment, the first single-chip microcomputer 1114 has a first a/D converter.

The first single chip microcomputer 1115 can calculate the phase difference between the first digital signal and the second digital signal, and the amplitude and frequency of the first digital signal and the second digital signal. By comparing the phase difference between the first digital signal and the second digital signal, the first single chip microcomputer 1115 can determine whether the moving body in the first detection region is close to the automatic door 1 or far from the automatic door 1, the magnitude of the amplitude of the movement of the moving body can be determined by the first single chip microcomputer 1115 through the amplitude of the first digital signal or the second digital signal, and the moving speed of the moving body and the distance between the moving body and the automatic door can be determined by the first single chip microcomputer 1115 through the frequency of the first digital signal or the second digital signal.

The driving mechanism 103 in this embodiment has a motor and a transmission mechanism, wherein a driving circuit of the motor receives a door opening signal and triggers the motor to operate after receiving the door opening signal, and the motor drives the movable door 1022 to move through the transmission mechanism. The specific structure of the door frame 101, the connection structure between the door frame 101 and the door 102, the specific structure of the driving mechanism 103, the connection structure between the driving mechanism 103 and the door frame 101, and the connection structure between the driving mechanism 103 and the movable door 1022 are all the prior art, and are not described herein again.

Of course, if the first mcu 1115 determines that the moving object in the first sensing region is far away from the automatic door 1, even if the motion amplitude reaches the door opening amplitude threshold, the speed reaches the door opening speed threshold, or the distance from the automatic door 1 reaches the door opening distance threshold, the first mcu 1114 does not output the first sensing signal. Therefore, the moving body which passes through the automatic door 1 from the door and enters the first sensing area can be prevented from triggering the automatic door 1 to open again, and the energy consumption of the automatic door 1 is reduced.

Please refer to fig. 4, which is a block diagram of a second microwave sensor according to a first embodiment of the present invention.

The second dual-element microwave module 1120 has the same structure as the first dual-element microwave module 1110, that is, has a second transmitting antenna, a second receiving antenna, a third mixer and a fourth mixer, wherein the third mixer and the fourth mixer are electrically connected to the third amplifier 1121 and the fourth amplifier 1122, respectively. The second transmitting antenna is configured to transmit an electromagnetic wave to the second sensing region, the second receiving antenna receives an electromagnetic wave reflected from the second sensing region, the second dual microwave module 1120 simultaneously inputs the electromagnetic wave transmitted by the second transmitting antenna and the reflected electromagnetic wave received by the second receiving antenna into a third mixer and a fourth mixer, the third mixer outputs a third doppler signal according to the electromagnetic wave and the reflected electromagnetic wave input thereto, the fourth mixer outputs a fourth doppler signal according to the electromagnetic wave and the reflected electromagnetic wave input thereto, and amplitudes and frequencies of the third doppler signal and the fourth doppler signal are equal. The third amplifier 1121 and the third filter 1123 respectively amplify and filter the third doppler signal, the fourth amplifier 1122 and the fourth filter 1124 respectively amplify and filter the fourth doppler signal, and the second single-chip microcomputer 1125 receives the third doppler signal and the fourth doppler signal, which are amplified and filtered, and outputs the second sensing signal according to the third doppler signal and the fourth doppler signal.

Specifically, the second one-chip microcomputer 1125 has a second a/D converter and a second memory, and the second a/D converter performs analog-to-digital conversion on the third doppler signal and the fourth doppler signal and converts the third doppler signal and the fourth doppler signal into a third digital signal and a fourth digital signal, respectively, which is the same as the first one-chip microcomputer 1115. The second single-chip microcomputer 1125 calculates the moving direction, the moving speed, the moving amplitude of the moving body and the distance between the moving body and the automatic door 1 in the second sensing region according to the phase difference, the frequency and the amplitude of the third digital signal and the fourth digital signal, and then compares the obtained moving speed, the moving amplitude and the distance between the moving body and the automatic door 1 with the door opening speed threshold, the door opening amplitude threshold and the door opening distance threshold preset in the second memory, and if the second single-chip microcomputer 1125 judges that the moving body is close to the automatic door 1, and the moving amplitude of the moving body reaches the door opening amplitude threshold, the speed reaches the door opening speed threshold, or the distance between the moving body and the automatic door 1 reaches the door opening distance threshold, the second single-chip microcomputer 1125 outputs a second sensing signal. The second single chip microcomputer 1125 determines that the moving object in the second sensing region is far away from the automatic door 1, even if the motion amplitude reaches the door opening amplitude threshold value, the speed reaches the door opening speed threshold value, or the distance between the moving object and the automatic door 1 reaches the door opening distance threshold value, the second single chip microcomputer 1125 does not output the second sensing signal, so that the moving object passing through the automatic door 1 from the outside of the door and entering the second sensing region is prevented from triggering the automatic door 1 to open again, and the energy consumption of the automatic door 1 is reduced.

The control host 110 has a timer, when the control host 110 receives the first sensing signal or the second sensing signal and opens the automatic door 1 through the driving mechanism 103, the internal timer starts timing, when the time for opening the automatic door 1 reaches the door closing threshold, and the control host 110 does not receive the first sensing signal or the second sensing signal again within the time for opening the automatic door 1, it outputs the door closing signal, and the driving mechanism 103 receives the door closing signal and operates according to the door closing signal to drive the movable door 1022 to move, and close the automatic door 1.

The second microwave sensor 112 of this embodiment further has a wireless receiver 1127, and the wireless receiver 1127 is electrically connected to the second single-chip microcomputer 1125. Specifically, the wireless receiver 1127 includes a third receiving antenna and a decoder, and the decoder is respectively in telecommunication connection with the third receiving antenna and the second single chip 1125. The third receiving antenna receives a remote control signal transmitted by the remote controller, the remote control signal is an electromagnetic wave, and the third receiving antenna can convert the received electromagnetic wave into an electric signal and output the electric signal converted by the electromagnetic wave. The decoder receives the electric signal converted by the electromagnetic wave and decodes the electric signal converted by the electromagnetic wave to obtain a fifth digital signal, wherein the fifth digital signal comprises an ID code, a rolling code, an encryption code and an instruction code. The second memory of the second single-chip microcomputer 1125 also pre-stores a decoding signal, where the decoding signal includes an ID code, a rolling code, and an encryption code, when the second single-chip microcomputer 1125 receives a fifth digital signal, the second single-chip microcomputer 1125 compares the ID code, the rolling code, and the encryption code of the fifth digital signal with the ID code, the rolling code, and the encryption code of the decoding signal, respectively, and analyzes the comparison, if the ID code, the rolling code, and the encryption code of the fifth digital signal are different from the ID code, the rolling code, and the encryption code of the decoding signal, the second single-chip microcomputer 1125 determines that the instruction code of the fifth digital signal is invalid, and if the ID code, the rolling code, and the encryption code of the fifth digital signal are the same as the ID code, the rolling code, and the encryption code of the decoding signal, the second single-chip microcomputer 1125 determines that the instruction code of the fifth digital signal is valid, and the. Specifically, the second single chip microcomputer 1125 outputs a fifth digital signal through the second output module 1126, and the control host 110 receives the fifth digital signal and adjusts the operation mode of the automatic door 1 according to the fifth digital signal.

The operation mode of the automatic door 1 of this embodiment includes a normally open mode, a normally closed mode, an automatic mode, an indoor unidirectional sensing mode and an outdoor unidirectional sensing mode, different mode keys of the remote controller are pressed, the remote controller transmits corresponding remote control signals, and after the different remote control signals are converted and decoded, the instruction codes of the fifth digital signals are also different, so that the second single chip 1125 can determine that the user needs to switch the operation mode of the automatic door 1 to any one of the normally open mode, the normally closed mode, the automatic mode, the indoor unidirectional sensing mode and the outdoor unidirectional sensing mode.

When the second single-chip microcomputer 1125 switches the operation mode of the automatic door 1 to the normally open mode according to the instruction code of the fifth digital signal, the control host 110 determines that the automatic door 1 is currently in the normally open mode according to the instruction code of the fifth digital signal, and correspondingly outputs a door opening signal, the driving mechanism 103 drives the movable door leaf 1022 to move according to the door opening signal, so that the automatic door 1 is opened, and meanwhile, the timer does not count time, so as to keep the automatic door 1 in the open state.

When the second single-chip microcomputer 1125 switches the operation mode of the automatic door 1 to the normally-closed mode according to the instruction code of the fifth digital signal, the control host 110 determines that the automatic door 1 is currently in the normally-closed mode according to the instruction code of the fifth digital signal, and correspondingly outputs a door-closing signal, the driving mechanism 103 drives the movable door leaf 1022 to move according to the door-closing signal, so that the automatic door 1 is closed, and meanwhile, the second microwave sensor 112 stops outputting the first sensing signal or the second sensing signal to the control host 110, so as to keep the automatic door 1 in the closed state.

When the second single-chip microcomputer 1125 switches the operation mode of the automatic door 1 to the automatic mode according to the instruction code of the fifth digital signal, it directly outputs the first sensing signal when it receives the first sensing signal, or it directly outputs the second sensing signal when it determines that there is a moving object in the second sensing region that needs to open the door, the control host 110 outputs the door opening signal according to the first sensing signal or the second sensing signal, the driving mechanism 103 operates according to the door opening signal to drive the movable door 1022 to move, so that the automatic door 1 is opened. When the automatic door 1 is opened, the timer starts to time, the time reaches the door closing threshold, and the control host 110 does not receive the first sensing signal or the second sensing signal again within the time period when the automatic door 1 is opened, and outputs a door closing signal, and the driving mechanism 103 receives the door closing signal, and operates according to the door closing signal to drive the movable door leaf 1022 to move, so that the automatic door 1 is closed.

When the second single-chip microcomputer 1125 switches the operation mode of the automatic door 1 to the indoor unidirectional induction mode according to the instruction code of the fifth digital signal, if it receives the first sensing signal, it does not output the first sensing signal, the automatic door 1 keeps the closed state, if it determines that there is a moving object in the second sensing region that needs to open the door, it directly outputs the second sensing signal, the control host 110 outputs the door opening signal according to the second sensing signal, and the driving mechanism 103 drives the movable door 1022 to move, so as to open the automatic door 1. When the automatic door 1 is opened, the timer of the control host 110 starts timing, and reaches the door closing threshold when the timing is finished, and the control host 110 outputs a door closing signal when the second sensing signal is not received again within the time period when the automatic door 1 is opened, the control host 110 outputs the door closing signal, and the driving mechanism 103 operates according to the door closing signal and drives the movable door leaf 1022 to move, so as to close the automatic door 1. Thus, the indoor unidirectional induction function of the automatic door 1 can be realized, and the influence of outdoor moving bodies can be avoided.

When the second single-chip microcomputer 1125 switches the operation mode of the automatic door 1 to the outdoor unidirectional induction mode according to the instruction code of the fifth digital signal, if it receives the first sensing signal, it directly outputs the first sensing signal, the control host 110 outputs the door opening signal according to the first sensing signal, and the driving mechanism 103 operates according to the door opening signal and drives the movable door 1022 to move, so as to open the automatic door 1. When the automatic door 1 is opened, the timer of the main control unit 110 starts timing, and when the timing reaches the door closing threshold, and the main control unit 110 does not receive the second sensing signal again within the time period when the automatic door 1 is opened, outputs a door closing signal, the main control unit 110 outputs the door closing signal, and the driving mechanism 103 operates according to the door closing signal and drives the movable door leaf 1022 to move, thereby closing the automatic door 1. If it is determined that there is a moving object in the second sensing region that needs to open the door, it does not output the second sensing signal, and the automatic door 1 remains closed. Thus, the outdoor one-way induction function of the automatic door 1 can be realized, and the influence of indoor moving bodies can be avoided.

In the present embodiment, since the second microwave sensor 112 is disposed on the outer surface of the door frame 101 of the automatic door 1 facing the indoor, the remote control signal can be received by the wireless receiver 1127 after penetrating through the housing of the second microwave sensor 112, the remote control signal does not need to penetrate through the door frame 101 made of metal, the requirement for the frequency of the remote control signal is low, the transmitting power of the remote controller is prevented from being high, and the power consumption is fast.

Referring to fig. 2, 3 and 4, the first microwave sensor 111 of the present embodiment further includes a first indication device 1117, the second microwave sensor 112 further includes a second indication device 1128, the first indication device 1117 is electrically connected to the first single-chip microcomputer 1115, the second indication device 1128 is electrically connected to the second single-chip microcomputer 1125, and the first indication device 1117 and the second indication device 1128 are respectively configured to send indication signals to the outside and the inside of the door to indicate an operation mode of the automatic door. Specifically, when the second mcu 1125 outputs the fifth digital signal to the second output module 1126, the first mcu 1115 and the second pointing device 1128 of the first sensor 111 simultaneously output the fifth digital signal, and the first mcu 1114 outputs the received fifth digital signal to the first pointing device 1117. The first indicating device 1117 and the second indicating device 1128 are respectively provided with an indicating lamp, and when the first indicating device 1117 and the second indicating device 1128 receive the fifth digital signal, the first indicating device 1117 and the second indicating device 1128 can respectively send out corresponding indicating signals through the indicating lamps according to valid command codes contained in the fifth digital signal. The operation modes of the automatic door 1 of the present embodiment include a normally open mode, a normally closed mode, an automatic mode, an indoor unidirectional sensing mode, and an outdoor unidirectional sensing mode, and the indicator light indicates different operation modes of the automatic door 1 by a color of the light, a flicker, or different states of the light. For example, when the automatic door 1 is in the normally open mode, the indicator lights of the first indicator device 1117 and the second indicator device 1128 are normally on, and the lights are green; when the automatic door 1 is in the normally-closed mode, the indicator lights of the first indicator 1117 and the second indicator 1128 are normally on, and the lights are red; when the automatic door 1 is in the automatic mode, the indicator lights of the first indicator 1117 and the second indicator 1128 are normally on, and the lights are blue; when the automatic door 1 is in the indoor unidirectional induction mode, the indicator light of the indicating device 12 is turned on in the form of a breathing light, and the light is green; when the automatic door 1 is in the outdoor one-way sensing mode, the indicator lights of the first and second indicator devices 1117 and 1128 are turned on in the form of breathing lights, and the lights are blue. Thus, the user can obtain feedback through the light states of the first indicating device 1117 and the second indicating device 1128 to know whether the automatic door 1 is successfully switched and the operation mode of the automatic door 1 in time.

Further, the automatic door 1 of the present embodiment further includes a locking mechanism 12, and the locking mechanism 12 is disposed in the groove of the door frame 101 and electrically connected to the control host 110. When the control host 110 determines that the automatic door 1 is currently in the normally-closed mode according to the valid command code included in the fifth digital signal, it sends a locking command to the locking mechanism 12 after the control driving mechanism 103 completes the door-closing event, and the locking mechanism 12 locks the closed movable door 1022.

When the up-lock key of the remote controller is pressed, the second one-chip microcomputer 1125 determines that the user needs to close the automatic door 1 according to the valid command code of the fifth digital signal corresponding to the remote control signal, outputs a close control signal, the control host 110 receives the close control signal and outputs a close signal according to the close control signal, and the driving mechanism 103 closes the automatic door 1 according to the close signal. Meanwhile, the control host 110 controls the locking mechanism 12 to lock the closed movable door leaf 1022 after the control driving mechanism 103 completes the door closing event.

Similarly, when the unlock key of the remote controller is pressed, the second single chip microcomputer 1125 determines that the user needs to open the automatic door 1 according to the valid command code of the fifth digital signal corresponding to the remote control signal, outputs an unlock control signal, and the control host 110 receives the unlock control signal and unlocks the locking mechanism 12 according to the unlock control signal, so that the movable door leaf 1022 can move. Meanwhile, the control host 110 also outputs a door opening signal, and the driving mechanism 103 drives the movable door 1022 to move according to the door opening signal, so that the automatic door 1 is opened. The specific structure of the locking mechanism 12, the connection structure between the locking mechanism 12 and the driving mechanism 103, and the door frame 101 of the locking mechanism 12, and their working principles are all the prior art, and are not described herein again.

Please refer to fig. 5 and 6, which are block diagrams of an automatic door and an anti-pinch device according to a second embodiment of the present invention. As shown in the drawings, the automatic door 1 of the first embodiment further has an anti-pinch device 13, the anti-pinch device 13 is disposed on the door frame 101 and electrically connected to the second microwave sensor 112 and the power module respectively, wherein the power module provides a working power to the anti-pinch device 13.

When the second microwave sensor 112 outputs the first sensing signal, the second sensing signal or the unlocking control signal, it also outputs a start signal, the anti-pinch device 13 receives the start signal and starts to operate according to the start signal, the camera module 131 of the operating anti-pinch device 13 collects image information of a third area and converts the collected image information into a corresponding sixth digital signal to be output, the processor 132 receives the sixth digital signal and outputs a third sensing signal through the third output module 133 according to the sixth digital signal, the second microwave sensor 112 receives the third sensing signal and outputs a brake signal according to the third sensing signal, the control host receives the brake signal and controls the driving mechanism 103 to brake and reverse according to the brake signal, and the movable door 1022 is kept open.

When the image processor 132 determines that no moving object remains in the third sensing region, it stops outputting the third sensing signal and stops operating to reduce power consumption. Meanwhile, when the control host 110 does not receive the braking signal again and the timing of the timer reaches the door closing threshold, the control host 110 outputs a door closing signal, and the driving mechanism 103 drives the movable door 1022 to move, so as to close the automatic door 1. Of course, the image processor 132 may also perform the contrast analysis by using a "frame difference method" or other methods that can effectively process and analyze the image and obtain the corresponding analysis result.

Further, if the image processor 132 determines that no moving object stays in the third sensing region for a period of time, the image processor 132 deletes the image contrast signal in the memory and stores the received sixth digital signal as a new image contrast signal in the third memory, so that the image contrast signal can be continuously updated, and the contrast analysis of the image processor 132 is more reliable.

Furthermore, the anti-jamming device 13 further includes an alarm 134, the alarm 134 is electrically connected to the image processor 132, and the alarm 134 is configured to send an alarm signal to warn the moving object staying in the third sensing region to leave. Specifically, when the image processor 132 determines that the time for the moving object to stay in the third sensing region reaches the warning time threshold, it outputs a warning control signal, and the warning indicator 134 receives the warning control signal and sends a warning signal according to the warning control signal. In the present embodiment, the alarm 134 is a buzzer that sounds to warn that the moving object staying in the third sensing region moves away after receiving the alarm control signal. Of course, the alarm 134 may be other alarm devices capable of sending out voice broadcast.

In other words, when a key fingerprint is entered, an authentication fingerprint needs to be entered first to obtain the authority to enter the fingerprint key. Then when a fingerprint is input through the fingerprint module 142, the fingerprint module 142 converts the input fingerprint into a numerical code and outputs the numerical code, the third single chip microcomputer 141 receives the input fingerprint and converts the input fingerprint into the numerical code, and compares the numerical code converted from the input fingerprint with the key fingerprint and the verification fingerprint stored in the fourth memory, if the comparison result is that the input fingerprint is the same as the verification fingerprint or the key fingerprint, the third single chip microcomputer 141 outputs an unlocking signal, the second single chip microcomputer 1125 receives the unlocking signal and outputs an unlocking control signal according to the unlocking signal, so that the control host 110 controls the locking mechanism 12 to unlock, and at the same time, the driving mechanism 103 is controlled to drive the movable door leaf 1022 to move, and the automatic door 1 is opened. In addition, when the input fingerprint is the same as the verification fingerprint, the user also obtains the authority of inputting the key fingerprint. If the comparison result is that the input fingerprint is not matched with the verification fingerprint and the key fingerprint, the third single chip microcomputer 141 does not output an unlocking signal, and the automatic door 1 is kept in a locked state and a closed state.

Specifically, when the fingerprint device 14 according to the present embodiment is shipped, the password can be entered through the plurality of numeric keys, and the third one-chip microcomputer 141 stores the password received for the first time as the verification password in the fourth memory. When the input keyboard 144 keys in the password again, the third single chip microcomputer 141 compares the received password with the verification password, if the comparison result is that the received password is the same as the verification password, the third single chip microcomputer 1125 outputs an unlocking signal to enable the second single chip microcomputer 1125 to output an unlocking control signal, so that the host computer 110 is controlled to control the locking mechanism 12 to unlock, and meanwhile, the driving mechanism 103 is controlled to drive the movable door leaf 1022 to move, so that the automatic door 1 is opened, if the comparison result is that the received password is not the same as the verification password, the third single chip microcomputer 141 does not output the unlocking signal, and the automatic door 1 keeps the locking and closing states.

And the factory recovery key is directly pressed down under the state that the authority for modifying the verification fingerprint and the verification password is not obtained, and the third singlechip 141 does not perform feedback. Therefore, the key fingerprint input, the verification fingerprint modification and the verification password need to acquire the authentication authority formed by the verification fingerprint, so that the fingerprint device 14 of the embodiment has higher security guarantee.

Further, the input keyboard 144 further has a close/lock key, when the close/lock key is pressed, the input keyboard 144 outputs a close/lock signal, the third mcu 141 receives the close/lock signal and outputs a lock signal according to the close/lock signal, the second mcu 1125 receives the lock signal and outputs a close control signal according to the lock signal, and the control host 110 outputs a close signal according to the close control signal to control the driving mechanism 103 to drive the movable door 1022 to move, so as to close the automatic door 1.
