Description

  The present invention relates to a taxi operation support system, and more particularly to a taxi operation support system characterized by prevention of driver's inadvertent mistakes during taxi operation, reduction of operation burden, and fraud prevention.

  Taxi drivers operate while paying attention to the performance of various operations as well as safe driving, but they make mistakes and feel burdened due to momentary relaxation, fatigue at night, and daily physical condition. There are still things to do.

  A specific example that is likely to cause mistakes is forgetting to press the actual vehicle (rental) button (hereinafter simply referred to as the “actual vehicle button”) of the taxi meter installed in the taxi. It is necessary to press the actual vehicle button whenever a passenger is loaded from an empty state, but sometimes it is accidentally forgotten. In this case, the original fare cannot be charged to the passengers and the driver will pay for it, or the taxi company may be damaged. Also, in some large commercial facilities and station premises, there is a rule that you do not rent without pressing the actual car button until you go to the public road because there is a distance until it goes to the public road because it is large, when you go on the public road It is easy to forget to press the actual vehicle button to be pressed.

  In other cases, when waiting for passengers waiting in a line at a taxi stand in a station or the like, they may not be aware that the previous taxi has moved forward, and may be urged to move forward in the subsequent taxi horn. If there are a lot of passengers in line, even if the line moves forward and stops, it is a short time so you will not notice that the previous taxi has advanced, but if there are few passengers, you will be forced to stop for a long time, Often, when doing other tasks, such as filling in a diary, you may not notice that the taxi just moved forward. It is also a burden to do other tasks such as filling in the operation diary while paying attention to the progress of the taxi just before.

  Furthermore, in other cases, it is a forgotten passenger. If there is something left behind, the passengers check with the taxi company, and the taxi company places a heavy burden on both the management of things left behind. For this reason, in order to prevent passengers from forgetting things, the driver always asks for confirmation when getting off the vehicle, or actually looks back at the rear seat from the driver's seat to check for missing items. The current situation is that you will not get lost because you get off the road, fall into the blind spot at the corner of the floor, or are dark and invisible at night.

  Furthermore, there is a fraudulent act in which a driver wears a fee without operating the taximeter correctly. For example, even if the passenger is on the road, run the taxi meter empty, and when you arrive at the destination, ask the passenger, “I accidentally forgot to press the actual car button. How much does it always come?” It is said that the passengers do not have a problem because they charge it cheaper than the usual amount. As described above, there are cases where a driver alone commits an illegal act, and there are cases where the driver and passengers conspire to carry out such an illegal act.

  Therefore, various inventions and devices have been made for preventing such mistakes, assisting operations, and preventing fraud. For example, in the prior art relating to prevention of forgetting to press a real car (rental) button of a taxi meter, there is a taxi meter alerting device disclosed in Japanese Utility Model Laid-Open No. 02-70269 (Patent Document 1). This device prevents the driver from forgetting to press the actual vehicle (renting) button by prompting the driver to start renting by emitting light or sound by a sensor that detects passengers. The sensors for detecting passengers are optical sensors, far-infrared sensors, etc., which are arranged above and below the boarding position, and pressure sensors are arranged inside the seat. It is described in. In addition, there was no particular discovery in the prior art relating to prevention of forgetting to press the actual vehicle (rental) button when entering a public road from a large-scale commercial facility or station.

  Further, in the prior art related to the detection of advance of the vehicle immediately before waiting for customers waiting in parallel at the taxi stand, there is a start confirmation system for the vehicle immediately before the actual Japanese Utility Model Publication No. 01-93157 (Patent Document 2). . This system is equipped with a distance sensor (ultrasonic transmitter and receiver) that measures the distance from the immediately preceding vehicle that is in tandem and is in a paused state on the front bumper of the vehicle, and the measured value by the distance sensor is set or stopped. An alarm is activated when the measured value immediately after is exceeded to inform the driver of the previous vehicle. The sensors that measure the distance are an ultrasonic transmitter and a receiver (see line 13 on page 3). The reflected wave reflected by the rear of the vehicle just before being sent from the transmitter is received by the receiver and transmitted. The distance is measured by calculating the time difference from reception to reception. (See page 3, line 18 to page 4, line 8) In addition to the ultrasonic wave, the gazette may use laser light, infrared light, visible light, microwave, or the like. Page 6 lines 7 to 10.

  Further, in the prior art related to the prevention of things left behind by passengers, there is a method and apparatus for preventing things left in the car disclosed in Japanese Patent Application Laid-Open No. 2006-338535 (Patent Document 3). This device can tell passengers that there is something left behind when they get off, and a different image difference area occupies the entire image area compared to the reference image stored in advance by the camera for in-vehicle shooting. Based on the ratio, the presence or absence of forgotten items is detected and notified by the passenger or driver. (See paragraph number 0005 etc. of the publication)

  Furthermore, as a prior art for preventing an illegal act due to an illegal operation of a taxi meter, there is a taxi meter disclosed in Japanese Patent Application Laid-Open No. 2001-22969 (Patent Document 4). This taximeter displays the pre-discount amount and the post-discount fare adjacent to each other in order to prevent fraudulent acts such as charging a pre-discount fare where the discounted fare should be applied. It is designed to make passengers easier to understand, to prevent fraud and to protect passengers. (See summary and paragraph numbers 0003-0006 of the publication)

  Japanese Utility Model Publication No. 02-70269   Japanese Utility Model Publication No. 01-93157   JP 2006-338535 A   Japanese Patent Laid-Open No. 2001-22969

  In the taximeter warning device of Patent Document 1, if the sensor that detects the passenger's boarding is an optical sensor, it is difficult to deal with different brightness such as daytime, nighttime, fine weather and cloudy sky, and the passenger is accurately identified. It may not be detected. In the case of a far-infrared sensor, it may not be possible to detect the far-infrared ray of the human body depending on the passenger's clothing, and the passenger cannot be accurately detected. In the case of a pressure sensor, the passenger may not be detected accurately depending on the weight of the passenger, the seating position, and the like. Each sensor has a problem about accurately and reliably detecting passengers.

  In the vehicle start confirmation system of Patent Document 2, the distance measuring sensor uses ultrasonic waves, laser beams, infrared rays, visible rays, microwaves, etc., and a transmitter and a receiver are attached to the front bumper. The general technique for measuring the distance by receiving the reflected wave reflected by the rear part of the vehicle immediately before being sent from the transmitter at the receiver and calculating the time difference from transmission to reception is only described. There was also the annoyance that the transmitter and the receiver had to be individually attached by routing the wiring to the front bumper outside the vehicle.

  In the in-car lost object prevention method and apparatus of Patent Document 3, the presence or absence of forgotten objects is detected by comparison with a reference image stored in advance using a camera for in-vehicle shooting. Similarly, it is extremely difficult to determine the reference image due to the difference in brightness such as daytime or nighttime, sunny weather or cloudy weather, or when shadows such as sunlight or streetlights are inserted into the car, causing shadows such as pillars. At the same time, the possibility of misjudgment of the presence or absence of forgotten items was extremely high.

  In the taxi meter of Patent Document 4, fraudulent acts such as simply displaying the pre-discount amount and post-discount fare adjacently on the taxi meter to clarify the fare, and where the discounted fare should be applied, claiming the pre-discount fare It is only intended to make it difficult to perform fraudulent acts, such as charging a fare without pressing the actual taxi button on the taxi meter even if a passenger with a large taxi company rides, and preventing illegal acts. It was not.

  As described above, the problems of the prior art described in Patent Documents 1 to 4 have been described, all of which prevent forgetting to press the actual vehicle button of the taxi meter, detect the advance of the vehicle immediately before waiting for passengers, prevent passengers from being left behind, simply cab It is a technology to solve each single problem such as fraud prevention by displaying the pre-discount amount and the post-discount fare adjacent to the meter, preventing driver accidental mistakes during taxi operation, reducing the burden of operation, fraud It was not a comprehensive system to prevent actions.

FIG. 1 is a diagram showing a state where a taxi operation support system is mounted on a taxi, and FIG. 2 is a block diagram of the taxi operation support system. First, the overall equipment configuration of the taxi operation support system of the present invention will be described with reference to FIGS. The taxi operation support system of the present invention is connected to the main body (1) and outputs an alarm when signals such as inter-vehicle sensors, human body sensors, monitor cameras, taxi meters, and vehicle speeds meet certain conditions. It provides support for comprehensive taxi operation to prevent driver accidental mistakes during taxi operation, reduce the burden of operation, and prevent fraudulent activity by issuing or displaying on a car navigation monitor.

  As shown in FIG. 1, the taxi operation support system includes a main body (1) mounted in a space under a seat and various types of sensors and taxi meters connected to the main body (1). On the main body (1), the inter-vehicle sensor (2) attached to the front window (inside the taxi) of the taxi toward the front of the vehicle, and attached to the rear seat near the taxi center console or under the change tray. Human body sensor (3), monitor camera (4) attached to the ceiling of the taxi vehicle so that the rear seat and floor can be photographed, OBD2 connector (5) provided in advance in the taxi vehicle, taxi provided in advance in the taxi Connected to the meter (6), from the inter-vehicle sensor (2), an inter-vehicle signal that detects that the immediately preceding taxi has advanced, and from the human body sensor (3), a human body signal that detects the presence or absence of passengers, a monitor camera (4 ) From the NTSC video signal to monitor the rear seats and floor, and from the OBD2 connector (5) A vehicle speed signal to detect the degree, from the taxi meter (6), unladen button taximeter (6a), the actual vehicle button (6b), which button of payment button (6c) are obtained whether the button signal has been pressed. In addition, a car navigation system (7) is connected to display captured images of the rear seat and floor of the monitor camera (4), and an alarm is generated in the main body (1) when the signals meet certain conditions. The monitor image of the rear seat and the floor is displayed on the monitor of the car navigation (7).

  As shown in the block diagram of FIG. 2, the main body (1) includes a control circuit (1a), an informing unit (1b), and a recording unit (1c). The control circuit (1a) has a signal input unit (1d). , A CAN communication unit (1e), a button position determination unit (1f), and a CPU (1g). An inter-vehicle sensor (2), a human body sensor (3), and a monitor camera (4) are connected to the signal input unit (1d), and an OBD2 connector (5) is connected to the CAN communication unit (1e) to determine the button position. A taximeter (6) is connected to the section (1f), and a car navigation (7) is connected to the CPU (1g). The configuration of the block diagram of FIG. 2 shows an example for easily explaining the taxi operation support system, and the block configuration is not particularly limited, and may be another block configuration.

The inter-vehicle sensor (2) will be described.
FIG. 3 is a block diagram of circuits of the inter-vehicle sensor (2) and the human body sensor (3). The inter-vehicle sensor (2) is connected to the signal input unit (1d) of the main body (1), and is configured by arranging a microwave circuit including a microwave transmission / reception circuit and a transmission path of 10.525 GHz on a substrate. It is a microwave Doppler sensor composed of a module (2a) and a control circuit (2b). As shown in FIG. 1, it is attached to the front window (inside of the taxi) of the taxi toward the front of the vehicle, detects that the taxi just before the train stops in parallel, and outputs a detection signal to the control circuit (2b). . The control circuit (2b) is composed of an amplifier circuit, a digital signal processor, and a band-pass filter, and has a Doppler frequency corresponding to the operation speed of the detection signal detected by the Doppler module (2a) immediately preceding the taxi in the column stop. It detects and monitors, and outputs a detection signal to the signal input part (1d) of the main body (1). The block diagram of the inter-vehicle sensor (2) and the human body sensor (3) in FIG. 3 represents an example of a circuit for monitoring the movement of the immediately preceding vehicle and the detection of the human body. The configuration is not particularly limited, and another block configuration may be used.

The human body sensor (3) will be described.
The human body sensor (3) is connected to the signal input unit (1d) of the main body (1) and is composed of a microwave transmission / reception circuit of 10.525 GHz and a transmission line, like the above-mentioned inter-vehicle sensor (2). A microwave Doppler sensor composed of a Doppler module (3a) and a control circuit (3b) configured by arranging a circuit on a substrate, as shown in FIG. 1, near the center console of a taxi or under a change tray. It is mounted towards the rear seat. A human body movement, respiration, and heartbeat are detected and a detection signal is output to the control circuit (3b). In detecting the human body, since a plurality of detection signals of body movement, breathing, and heartbeat are used, the human body can be reliably detected. The control circuit (3b) is composed of an amplifier circuit, a digital signal processor, and a band pass filter, and detects and monitors the Doppler frequency corresponding to the movement speed of the human body, the breathing, and the heartbeat detected by the Doppler module (3a). The detection signal is output to the signal input unit (1d) of the main body (1).

  FIG. 4 is a waveform diagram showing the detection state of the human body of the human body sensor (3), and is a waveform diagram of body motion, respiration, and heartbeat detected by the human body sensor (3). Further, as shown in FIG. 4, each waveform appears when a passenger gets on, and the presence or absence of a human body is detected by disappearing each waveform when getting off.

  The graph showing the body movement in the upper part of FIG. 4 shows time on the X axis and the level of movement (more or less) on the Y axis. The larger the vertical amplitude on the Y axis, the more active the movement, and the smaller the lower the axis, the gentler the movement. In addition, it can be determined that there is a human body at the stage where the waveform of body movement appears, that is, the passenger has boarded, and if the waveform of body movement disappears in the middle, it indicates that there is no body movement, no human body, That is, it is determined that the passenger has got off the vehicle. Even if the body movement waveform disappears, if the later-described breathing and heartbeat are detected, it is determined that the passenger is on board, and in this case, it is generally determined that the patient is sleeping. Can do.

  The graph showing the respiration in the middle of FIG. 4 shows time on the X-axis and the level of breathing (deep and shallow) on the Y-axis. The larger the vertical amplitude on the Y axis, the deeper the breath and the smaller the shallower the breath, the shallower the breath. Further, it is determined that the longer the amplitude period of the waveform on the X-axis, the slower the breathing, and the shorter, the faster the breathing. In addition, it can be determined that there is a human body when the respiration waveform appears, that is, the passenger has boarded, and if the respiration waveform disappears in the middle, it indicates that there is no breathing, that is, there is no human body, that is, the passenger It is determined that the vehicle has got off. Furthermore, if the amplitude of the respiratory waveform disappears in the middle, it is determined that the passenger's breathing has stopped, and if the body movement is not detected and only the heartbeat is detected, the passenger is generally not sleeping. It can be determined that the patient is in breathing.

  The graph showing the heart rate in the lower part of FIG. 4 shows time on the X axis and the level of heart rate on the Y axis. It is determined that the longer the amplitude period of the waveform on the X-axis, the slower the heartbeat, and the shorter, the faster the heartbeat. Also, if the amplitude of the heartbeat waveform disappears halfway, it is determined that the passenger has stopped cardiac, and if body movement and breathing are not detected, either the person died, or he got off and the human body disappeared However, it is not necessary to provide a condition for determining whether the person has died or the human body has disappeared on the system.

  As described above, since the human body sensor (3) uses the microwave Doppler sensor and uses a plurality of detection signals of the body movement (passenger) of the human body (passenger), the body movement, the breathing, or the heartbeat, Even if it cannot be detected for some reason, if any detection signal is present, the human body can be reliably detected as a human body. Although it is possible to determine the physical condition of passengers from detection signals of body movement, breathing, and heartbeat, a taxi while traveling does not cause the passengers to move finely. Since movement may occur and it may be erroneously determined that there is body movement, further research is needed to reliably determine the physical condition of the passenger.

The monitor camera (4) will be described.
The monitor camera (4) is a monitor camera that outputs an NTSC video signal connected to the signal input unit (1d) of the main body (1), and monitors the entire rear seat and floor as shown in FIG. For example, it is attached in the vicinity of the center of the ceiling in order to confirm the forgotten items. In addition, specifications that can sufficiently monitor the rear seat and the floor with a light quantity equivalent to that of a room lamp even at night, such as a lens F value of 2.0, a pixel count of 310,000 pixels, and a wide viewing angle. Are preferably used. The video of the NTSC video signal output from the monitor camera (4) is displayed on the monitor of the car navigation (7) connected to the CPU (1g) of the main body (1) separately. The condition displayed on the monitor of the car navigation (7) is that the payment button (6c) of the taximeter (6) is pressed, and the condition is automatically switched from the map screen of the monitor of the car navigation (7). The image of the rear seat is clearly displayed regardless of daytime or nighttime, and the driver can surely check whether there is something left behind for the passenger.
