The sensing controller 14 determines whether there is a pedestrian at the entrance according to the sensing signals output from the two FMCW microwave sensors 13 disposed at the entrance, and determines whether the pedestrian moving direction at the entrance is directly close to the entrance, directly away from the entrance, or simply passes in front of the entrance. In this manner, the induction controller 14 can output different control signals to adjust the state of the power plant 16 based on different determinations.
Please refer to fig. 3, which is a block diagram of an FMCW microwave sensor according to a first embodiment of the present invention.

Please refer to fig. 4, which is a block diagram of a single chip according to a first embodiment of the present invention. As shown in the figure, in the present embodiment, the single chip microcomputer 130 includes a DA output unit 1300, an AD conversion unit 1301, a digital filter unit 1302, a digital signal processing unit 1303 and an output unit 1304, wherein the DA output unit 1300 is electrically connected to the frequency modulation circuit 131, the AD conversion unit 1301 is electrically connected to the amplifier 136, and is electrically connected to the output unit 1304 through the digital filter unit 1302, the digital signal processing unit 1303, and the output unit 1304 is electrically connected to the output module 137.
The operation of the FMCW microwave sensor 13 is described in detail below, with reference to fig. 3 and 4. In this embodiment, the DA output unit 1300 in the single chip microcomputer 130 is configured to control the frequency modulation circuit 131 to continuously generate a modulation signal, the frequency modulation circuit 131 continuously transmits the modulation signal to the frequency modulation interface of the FMCW radar transceiver 132, and when the FMCW radar transceiver 132 receives the modulation signal, the FMCW radar transceiver transmits a high-frequency electromagnetic wave with a certain bandwidth and a continuous frequency sweep in a radiation manner through the transmitting antenna 133 according to the modulation signal, wherein the frequency of the modulation signal determines the frequency sweep speed, and the higher the frequency of the modulation signal, the faster the frequency sweep speed.
Further, when the transmission electromagnetic wave radiated from the transmission antenna 133 encounters an obstacle to generate a reflected electromagnetic wave, the reception antenna 134 continuously receives the reflected electromagnetic wave and transmits the reflected electromagnetic wave to the FMCW radar transceiver 132. The FMCW radar transceiver 132 has a mixer, and the FMCW radar transceiver 132 inputs the received reflected electromagnetic wave and the electromagnetic wave being transmitted by the transmitting antenna 133 into the mixer, so that the frequency difference between the reflected electromagnetic wave received by the FMCW radar transceiver 132 and the electromagnetic wave being transmitted by the transmitting antenna 133 exists because the transmitted electromagnetic wave is a linear frequency-swept electromagnetic wave, and thus, the mixer can generate an intermediate frequency signal.
Furthermore, the FMCW radar transceiver 132 transmits the intermediate frequency signal to the filter 135, the filter 135 filters the intermediate frequency signal to filter out the low frequency signal and other interference signals contained in the intermediate frequency signal to obtain an effective signal, the filter 135 transmits the filtered intermediate frequency signal to the amplifier 136, and the amplifier 136 amplifies the filtered intermediate frequency signal, so that the amplitude of the useful high frequency signal in the intermediate frequency signal is enhanced, thereby being more beneficial to the acquisition and analysis of the single chip microcomputer 130.
Further, the amplifier 136 transmits the amplified intermediate frequency signal to the AD conversion unit 1301 of the single chip microcomputer 130, the AD conversion unit 1301 performs analog-to-digital conversion on the amplified intermediate frequency signal to generate a corresponding digital signal, and the digital filtering unit 1302 performs filtering processing on the digital signal to filter jitter and other noise in the digital signal, such as sampling.
Further, the digital filtering unit 1302 transmits the filtered digital signal to the digital signal processing unit 1303, and the digital signal processing unit 1303 performs a series of algorithm analyses on the digital signal, in the algorithm analyses, the digital signal processing unit 1303 adopts the frequency spectrum and the phase spectrum of the digital signal by the FFT algorithm, each frequency point of the frequency spectrum of the digital signal corresponds to information of obstacles at different distances, the obstacle corresponding to the lower frequency point is closer to the FMCW microwave inductor 13, and the obstacle corresponding to the higher frequency point is farther from the FMCW microwave inductor 13. The digital signal processing unit 1303 generates a sensing signal corresponding to the digital signal, and transmits the sensing signal to the sensing controller 14 through the output unit 1304 and the output module 137 in sequence. It should be noted that the FMCW microwave sensor 13 will use a completely stationary object as a background environment, and does not consider the distance information of a moving pedestrian or object.
Thus, the sensing controller 14 can obtain the distance from the pedestrian or the moving object to the FMCW microwave sensor 13 through the sensing signal continuously output by each FMCW microwave sensor 13 arranged at the entrance, and further judge whether the pedestrian or the moving object is close to or far away from the FMCW microwave sensor 13 through the change of the distance, and the sensing signal continuously output by the two FMCW microwave sensors 13 can further determine whether the moving direction of the pedestrian or the moving object is directly close to the entrance, directly far away from the entrance or only passes through the front of the entrance, and further correspondingly output a control signal, so as to adjust the running state of the microwave-sensing energy-saving handrail elevator 1. For example, referring to fig. 5, fig. 5 is a schematic radiation diagram of an FMCW microwave sensor according to a first embodiment of the present invention, as shown in the figure, when the pedestrian moves from the left side to the right side in the figure in compliance with the direction A, the distance between the pedestrian and the two FMCW microwave sensors 13 changes from far to near and then from near to far, however, before the pedestrian begins to get away from the FMCW microwave sensor 13 on the right side in the figure, the distance between the pedestrian and the FMCW microwave sensor 13 on the left side in the figure changes from far to near and then from near to far, meanwhile, the distance change of the pedestrian and the FMCW microwave inductor 13 positioned at the right side on the figure is continuously close, in the case where the pedestrian starts to get away from the FMCW microwave sensor 13 located on the right side in the figure and the distance change of the pedestrian from the two FMCW microwave sensors 13 is continuously kept away, the sensing controller 14 judges that the pedestrian passes before the entrance. If the sensing controller 14 determines that the distance between the pedestrian moving continuously and the two FMCW microwave sensors 13 changes from far to near, it determines that the moving direction of the pedestrian is directly close to the entrance. If the sensing controller 14 determines that the pedestrian moving continuously has a distance variation from both the FMCW microwave sensors 13 from near to far, it determines that the moving direction of the pedestrian is directly away from the entrance.
The following describes how the induction controller 14 of the present embodiment outputs a corresponding control signal according to different determinations to adjust the operating state of the power plant 16. When the induction controller 14 of the microwave induction energy-saving escalator 1 in the running state judges that the time of no pedestrian at the exit is accumulated to a certain time limit, the induction controller outputs a first control signal to the main controller 15, and the main controller 15 controls the power equipment 16 to stop running according to the first control signal so as to save energy.
When the induction controller 14 of the microwave induction energy-saving escalator 1 in the stopped state judges that a pedestrian is directly approaching the entrance, and the distance from the pedestrian to the FMCW microwave inductor 13 reaches a first distance threshold value for triggering operation, or the pedestrian passes through the front of the entrance, and the distance from the pedestrian to the FMCW microwave inductor 13 reaches a second distance threshold value for triggering operation, the induction controller outputs a second control signal to the master controller 15, the master controller 15 controls the power equipment 16 to start to operate according to the second control signal, the power equipment 16 drives the operation ladder 10 and the armrest 12 to rotate, wherein the first distance threshold value is greater than the second distance threshold value, so as to reduce the probability of mistakenly triggering the power equipment 16 to operate, and further reduce energy waste.
When the induction controller 14 of the microwave-induced energy-saving escalator 1 in the stopped state judges that a pedestrian directly approaches the entrance without reaching the first distance threshold value for triggering operation and is further away from the entrance, and the pedestrian passes from the front of the entrance without reaching the second distance threshold value for triggering operation, the induction controller does not output a control signal to the master controller 15, and the power equipment 16 continuously keeps the stopped state.
When the induction controller 14 of the microwave induction energy-saving handrail elevator 1 in the running state judges that a pedestrian directly approaches the entrance and reaches the first distance threshold value for triggering the running and a pedestrian passes in front of the entrance and reaches the second distance threshold value for triggering the running, the induction controller does not output a control signal to the main controller 15, and the power equipment 16 continuously keeps running.
Referring to fig. 6, fig. 6 is a schematic diagram of an inductive controller according to a first embodiment of the present invention. As shown in the figure, the induction controller 14 of the microwave induction energy-saving escalator 1 of the present embodiment has two distance control buttons 140, the first distance threshold for triggering the operation of the power equipment 16 can be adjusted by one distance control button 140, and the second threshold can be fixedly set to be half of the first distance threshold by one distance control button 140, so that the distance for triggering the operation of the microwave induction energy-saving escalator 1 can be reasonably adjusted according to actual requirements.
Preferably, the induction controller 14 of the microwave-induced energy-saving escalator 1 of the present embodiment further includes a display module 141, and the display module 141 is configured to display the current trigger distance threshold, in the present embodiment, the display module 141 displays the current trigger distance threshold in real time by using a display nixie tube, so as to conveniently and correctly adjust the distance for triggering the microwave-induced energy-saving escalator 1 to run.
It should be noted that the independent structures of the operation ladder 10, the baffle 11, the handrail 12, the power equipment 16 and the main controller 15 of the microwave induction energy-saving handrail elevator 1 and the connection structure therebetween are the prior art, and are not described herein again.
Please refer to fig. 7, which is a block diagram of a microwave induction energy-saving escalator according to a second embodiment of the present invention. The microwave induction energy-saving escalator 1 of the present embodiment is of a bidirectional operation type, and has four FMCW microwave inductors 13, each FMCW microwave inductor 13 is electrically connected to an induction controller 14, and two FMCW microwave inductors 13 are respectively disposed at two entrances and exits of the microwave induction energy-saving escalator 1. When the running direction of the microwave-induced energy-saving escalator 1 is from bottom to top in the figure, the entrance located at the lower part on the figure is an entrance, the entrance located at the upper part on the figure is an exit, pedestrians enter from the lower part and leave from the upper part, and conversely, when the running direction of the microwave-induced energy-saving escalator 1 is from top to bottom in the figure, the entrance located at the upper part on the figure is an entrance, the entrance located at the lower part on the figure is an exit, pedestrians enter from the upper part and leave from the lower part. Thus, the induction controller 14 can judge whether there is a pedestrian at the entrance according to the sensing signals output by the two FMCW microwave inductors 13 arranged at the exit, judge whether the pedestrian at the entrance moves in a direction directly close to the entrance, away from the entrance or only pass through the entrance from the front, judge whether there is a pedestrian at the exit according to the sensing signals output by the two FMCW microwave inductors 13 arranged at the exit, judge whether the pedestrian at the exit moves in a direction directly close to the exit, away from the exit or only pass through the exit from the front, and then send out corresponding control signals according to different judgments, and adjust the operating state of the microwave induction energy-saving handrail elevator 1.
The following describes how the induction controller 14 of the present embodiment outputs a corresponding control signal according to different determinations to adjust the state of the power plant 16. When the induction controller 14 of the microwave induction energy-saving escalator 1 in the running state judges that no pedestrian exists at the exit and the entrance, the induction controller outputs a third control signal to the main controller 15, and the main controller 15 controls the power equipment 16 to stop running according to the third control signal, so as to save energy.
When the induction controller 14 of the microwave induction energy-saving escalator 1 in the running state judges that a pedestrian directly approaches to the entrance and reaches the first distance threshold value of the trigger running, and when the pedestrian passes through the entrance from the front and reaches the second distance threshold value of the trigger running, or the induction controller 14 judges that no pedestrian appears at the entrance, and the exit has a pedestrian directly approaches and reaches the first distance threshold value of the trigger running, and when the pedestrian passes through the exit from the front and reaches the second distance threshold value of the trigger running, the control signal is not output to the master controller 15, the power equipment 16 continuously keeps the original running state, the running direction of the microwave induction energy-saving escalator 1 is not changed, the frequent change of the running direction is avoided, and the disorder of the order is caused.
When the induction controller 14 of the microwave induction energy-saving escalator 1 in a stopped state judges that a pedestrian directly approaches one of the two entrances and the distance from the pedestrian to the FMCW microwave inductor 13 reaches a first distance threshold value for triggering operation and no pedestrian directly approaches the other entrance or the pedestrian directly approaches the other entrance and the distance from the pedestrian to the FMCW microwave inductor 13 does not reach a first distance threshold value for triggering operation, or the pedestrian passes through the other entrance from the front of the other entrance and the distance from the pedestrian to the FMCW microwave inductor 13 does not reach a second distance threshold value for triggering operation, the other entrance outputs a fourth control signal to the master controller 15, the master controller 15 controls the power equipment 16 to start to operate according to the fourth control signal, drives the operation ladder 10 and the armrest 12 to rotate, and the direction in which the microwave induction energy-saving escalator 1 starts to operate meets the riding requirement of the pedestrian for triggering operation, namely, the entrance and the exit of the two entrances and exits of the microwave induction energy-saving escalator 1, which are close to the pedestrian running under triggering, are entrances, and the other entrance and the exit are exits.
Similarly, when the induction controller 14 of the microwave-induced energy-saving escalator 1 in a stopped state determines that a pedestrian passes in front of one of the two entrances, and the distance between the pedestrian and the FMCW microwave inductor 13 reaches a second distance threshold value for triggering operation, and no pedestrian at the other entrance is directly close to the other entrance, or the pedestrian at the other entrance is directly close to the FMCW microwave sensor 13 but the distance from the pedestrian to the FMCW microwave sensor 13 does not reach the first distance threshold value for triggering the operation, or the pedestrian passes in front of the other entrance and the distance from the pedestrian to the FMCW microwave sensor 13 does not reach the second distance threshold value for triggering the operation, the induction controller 14 also outputs a fourth control signal to the main controller 15, and the main controller 15 controls the power device 16 to start operating according to the fourth control signal, so as to drive the operation ladder 10 and the handrail 12 to rotate, and the direction of the microwave induction energy-saving escalator 1 starting to run meets the riding requirement of the pedestrian triggering to run.
Thus, when the microwave-induced energy-saving escalator 1 of the present embodiment is in a stop state, as long as any two FMCW microwave inductors 13 disposed at two entrances and exits sense that a pedestrian approaches, and when the distance between the pedestrian and the FMCW microwave inductors 13 reaches the first distance threshold or the second distance threshold that triggers the operation, the induction controller 14 outputs the fourth control signal, and then controls the power device 16 to operate through the master controller 15, and drives the operation ladder 10 and the handrail 12 to operate in the direction that meets the requirement of the pedestrian, so that the microwave-induced energy-saving escalator 1 of the present embodiment can flexibly automatically adjust the operation direction according to the requirement of the pedestrian, and has higher practicability.
