JP 2005-31841 A

  In the conventional traffic management device as described above, when the passerby tries to pass the ticket gate with an accompanying item such as a baby carriage, the passerby precedes the passerby before the main body reads the ticket. In some cases, an accompanying person may be erroneously detected as a passerby and cannot pass smoothly. This problem is not limited to automatic ticket gates, and also occurs when traffic management is performed at the entrance of a bicycle parking lot, for example.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a traffic management device that can make a passerby accompanied by an accompanying person more smoothly.

  The traffic management device according to the present invention detects a passer-by who is going to pass through the gate without inputting authentication information, being arranged at a distance from each other along the passer-by direction of the passer-by on the gate side of the input means. A plurality of passer detection sensors, a recognition sensor unit for recognizing whether or not the passer is accompanied by an accompaniment before the passer reaches the position of the passer detection sensor, and a passer by The memory means storing the accompaniment recognition information, which is the output of the recognition sensor unit when accompanied, and the passer-by means the accompaniment based on the output of the recognition sensor unit and the accompaniment recognition information of the memory means. If the recognition means recognizes whether or not the passerby is accompanied by an accompaniment, the accompaniment that precedes the passer is prevented from being erroneously detected as a passerby. In order to And a passerby detecting sensor control means for switching the sensor.

  According to the pass management apparatus of the present invention, the recognition means recognizes whether or not the passer is accompanied by an accompaniment based on the output of the recognition sensor unit and the accompanying object recognition information of the memory means, and detects the passer-by. The sensor control means is a passerby that is effective in order to prevent a passerby from being erroneously detected as a passerby when the recognizer recognizes that the passerby is accompanied by an attendant. Since the detection sensor is switched, it is possible to reduce the possibility that an accompaniment will be erroneously detected as a passerby when the passerby tries to pass through the gate with an accompaniment. Can be.

The best mode for carrying out the present invention will be described below with reference to the drawings.
Embodiment 1 FIG.
1 is a block diagram showing a traffic management apparatus according to Embodiment 1 of the present invention. FIG. 2 is a top view showing the main part of FIG. In FIG. 1, a traffic management device main body 1 is installed at a gate where traffic of a passerby is managed. The traffic management apparatus body 1 includes an input unit 2, an authentication unit 3, a gate door control unit 4, a memory unit 5, first to fifth passer detection sensors 6a to 6e, a passer detection sensor control unit 7, and a recognition unit 8. Is included. Note that the authentication unit 3, the gate door control unit 4, the passer detection sensor control unit 7, and the recognition unit 8 are based on an information storage unit (RAM and ROM) for storing information such as a program and the information in the information storage unit. And a processing unit (CPU) that performs arithmetic processing.

  The input means 2 is used for inputting authentication information by a passerby. As the input means 2, a card reader or the like that reads an ID number as authentication information from an ID card carried by the user is used. That is, the authentication information input operation by the passerby is an operation for causing the card reader to read the ID number. The authentication information input by the input unit 2 is input to the authentication unit 3.

  The gate door control means 4 controls opening and closing of a gate door (not shown) that restricts passage of passers-by. The memory means 5 stores authentication information that is permitted to pass, and passerby recognition information, accompanying object recognition information, and separation distance information, which will be described in detail later. If the authentication means 3 collates the authentication information input by the input means 2 with the authentication information of the memory means 5 and determines that the information that matches the input authentication information is stored in the memory means 5, A permission signal is input to the door control means 4. The gate door control means 4 opens the gate door according to the input of the permission signal and permits the passerby to pass. In addition, when the authentication unit 3 determines that the one that matches the input authentication information is not stored in the memory unit 5, the authentication unit 3 inputs a prohibition signal to the gate door control unit 4. The gate door control means 4 closes the gate door according to the input of the prohibition signal and prohibits the passerby from passing.

  The first to fifth passer-by detection sensors 6a to 6e are arranged at a distance from each other along the passer's pass direction on the gate side of the input unit 2. The first to fifth passer-by detection sensors 6a to 6e detect passers who want to pass through the gate without inputting authentication information. The operations of the first to fifth passer-by detection sensors 6a to 6e are controlled by the passer-by detection sensor control means 7. The passer-by detection sensor control means 7 normally validates only the first passer-by detection sensor 6a that is the closest to the passer-by. If the passerby is detected by any of the first to fifth passer detection sensors 6a to 6e that are validated before the verification of the authentication information, the authentication unit 3 causes the gate door control unit 4 to A prohibition signal is input to prohibit passers-by.

  Here, on the floor in front of the gate, for example, a recognition sensor for recognizing whether a passerby is accompanied by a companion such as a bicycle before reaching the position of the passer detection sensors 6a to 6e. Part 9 is installed. Although only one representative is shown in FIG. 2, the recognition sensor unit 9 includes a plurality of pressure sensors 10 arranged in a matrix. Specifically, each pressure sensor 10 is disposed at the intersection of each line parallel to the X coordinate axis and each line parallel to the Y coordinate axis shown in FIG. In other words, being arranged in a matrix means that a plurality of columns are arranged vertically and horizontally. When a passerby passes on the recognition sensor unit 9, the pressure sensor 10 in the sole region 11 of the passerby is turned on. Similarly, when the bicycle passes on the recognition sensor unit 9 accompanied by a passerby, the pressure sensor 10 in the tire ground contact area 12 of the bicycle is turned on.

  The passer-by identification information stored in the memory means 5 includes, for example, the area (the sole area and its shape) of the pressure sensor 10 that is turned on by the passer's sole for each type of footwear such as athletic shoes or high heels. Show. In addition, the accompaniment recognition information stored in the memory means 5 includes, for each type of an accompaniment such as a bicycle or a baby carriage, a region of the pressure sensor 10 that is turned on by the tire contact of the accompaniment (the tire contact area and their contact area). Interval).

  The recognition unit 8 obtains the pressure detection position in the XY coordinate system in the matrix based on the output of each pressure sensor 10. The recognizing means 8 determines the presence or absence of a passer based on the output of each pressure sensor 10 and the passerby recognition information and the accompanying object recognition information in the memory means 5. Here, when the passer-by passes on the recognition sensor unit 9, only the passer-by passes, when the passer-by passes while pushing an accompanying item such as a bicycle, and when the passer-by passes an accompaniment such as a bicycle. There is a case of passing on a thing. That is, the recognition means 8 recognizes that there is a passer if the output of each pressure sensor 10 corresponds to at least passer-by identification information and accompanying object recognition information.

  Further, when recognizing means 8 recognizes that there is a passerby, it determines whether or not the passerby is accompanied by a companion. When it is determined that the output of each pressure sensor 10 corresponds only to the passer-by identification information, the recognizing unit 8 recognizes that the passer-by is not accompanied by an accompanying person, and the passer-by detection signal is passed to the passer-by detection sensor control unit 7. input. When the passer detection sensor control means 7 detects the passer detection signal from the recognition means 8, the normal control of the first to fifth passer detection sensors 6a to 6e, that is, only the first passer detection sensor 6a. Valid.

  On the other hand, the recognizing means 8 recognizes that the passer is accompanied when the output of each pressure sensor 10 corresponds to both the passer-by identification information and the accompanying object recognition information, and when the output corresponds to only the accompanying object recognition information. Recognize that something is accompanied. That is, the recognizing unit 8 recognizes whether or not the passerby is accompanied by an accompaniment, based on the output of the recognition sensor unit 9 and the accompaniment recognition information of the memory unit 5. When the recognizing means 8 recognizes that the passerby is accompanied by an accompaniment, the recognizing means 8 obtains the preceding amount of the accompaniment with respect to the passerby based on the output of each pressure sensor 10 and the distance information of the memory means 5. Specifically, the separation distance information of the memory means 5 indicates the separation distance between the front wheel (grounding position) of the accompanying object and the tip position for each accompanying object type. Note that this separation distance is a generally estimated separation distance. Based on the output of each pressure sensor 10, the recognizing means 8 obtains a separation distance in the direction of travel (the X-axis direction in FIG. 2) between the foot of the passerby who is stepping forward and the front wheel of the accompanying object. And the recognition means 8 calculates | requires the preceding amount of the accompanying object with respect to a passerby by adding the separation information of the recognized accompanying object to the calculated separation distance.

  The recognizing means 8 obtains the preceding amount of the accompaniment with respect to the passerby, and then inputs the accompanying object detection signal together with the preceding amount to the passer-by detection sensor control means 7. The passer-by detection sensor control unit 7 switches the first to fifth passer-by detection sensors 6a to 6e to be valid based on the preceding amount when the preceding amount and the accompanying object detection signal from the recognition unit 8 are detected. In other words, the passer-by detection sensor control means 7 prevents the passersby detection sensors 6a to 6e from erroneously detecting the accompanying accompaniment as a passer-by in accordance with the preceding amount of the companion. The effective sensor is determined from the second to fifth passer detection sensors 6b to 6e behind the passer detection sensor 6a.

  Next, the operation will be described. FIG. 3 is a flowchart showing a traffic management operation performed by the traffic management device body 1 of FIG. In the drawing, when the power of the traffic management device main body 1 and the recognition sensor unit 9 is turned on, the passer-by is determined based on the output of each pressure sensor 10 and the passer-by identification information and the accompanying object recognition information in the memory means 5. Whether or not there is is recognized by the recognition means 8 (step S1).

  At this time, when it is recognized that there is a passerby, it is recognized by the recognition means 8 whether or not the passer is accompanied by an accompaniment (step S2). A passer detection signal is input to the passer detection sensor control means 7 from 8, and only the first passer detection sensor 6a is validated by the passer detection sensor control means 7 in response to the input of the passer detection signal. (Step S3).

  On the other hand, when it is recognized that the passerby is accompanied by an accompaniment, the recognition unit 8 obtains the preceding amount of the accompaniment with respect to the passer based on the output of each pressure sensor 10 and the distance information of the memory unit 5. At the same time (step S4), the preceding amount and the accompanying object detection signal are input from the recognizing means 8 to the passer detection sensor control means 7, and the preceding amount and the accompanying object detection signal are input in advance according to the input of the preceding amount and the accompanying object detection signal. The sensor to be activated is switched to any one of the second to fifth passer-by detection sensors 6b to 6e so that the accompanying companion is not erroneously detected as a passer-by (step S5).

  Next, verification of the authentication information input by the input unit 2 is performed by the authentication unit 3 (step S6), and it is determined that authentication information that matches the input authentication information is stored in the memory unit 5. In this case, the permission signal is input to the gate door control means 4, and the gate door is opened (step S7). Next, based on the outputs of the passer detection sensors 6a to 6e that are validated, it is determined by the authentication means 3 whether or not the pass of the gate by the passer is completed (step S8), and the pass is completed. When it is determined that the gate door is closed (step S9), this traffic management operation is terminated. This operation is repeatedly performed when the power of the traffic management device main body 1 and the recognition sensor unit 9 is turned on.

  On the other hand, when it is determined that the authentication information that matches the input authentication information is not stored in the memory means 5, a prohibition signal is input to the gate door control means 4, and the gate door is kept closed. This traffic management operation is terminated.

  In such a traffic management device, the recognition means 8 recognizes whether or not the passer is accompanied by an accompaniment based on the output of the recognition sensor unit 9 and the accompaniment recognition information of the memory means 5. The detection sensor control means 7 is effective in order to prevent an accompaniment that precedes the passer from being erroneously detected as a passer when the passer is recognized as accompanied by an accompaniment. Since the passer detection sensors 6a to 6e to be switched are switched, the possibility that the passerby is erroneously detected as a passer when the passer tries to pass through the gate with the companion can be reduced. Traffic can be made smoother.

  The recognition sensor unit 9 includes a plurality of pressure sensors 10 installed in a matrix on the floor in front of the gate, and the accompanying object recognition information indicates an area of the pressure sensor 10 that is turned on by the tire grounding of the accompanying object. Therefore, it is possible to more reliably recognize that the passerby is accompanied by an accompaniment, and more reliably reduce the possibility that the accompaniment is erroneously detected as a passerby.

  When the recognition means 8 determines that the passerby is accompanied by an accompaniment, the recognition means 8 obtains the preceding amount of the accompaniment for the passerby based on the output of each pressure sensor 10 and the separation distance information of the memory means 5, Since the person detection sensor control means 7 determines the passer-by detection sensors 6a to 6e to be effective based on the preceding amount of the companion obtained by the recognizing means 8, it is more appropriate according to the preceding amount of the companion. The passerby detection sensors 6a to 6e can be made effective, and the possibility that the accompaniment is erroneously detected as a passerby can be reduced more reliably, and the passerby with the accompaniment can be made smoother. it can.

When a passerby and an accompanying person pass on the recognition sensor unit 9, the pressure detection position by the sole of the passerby is intermittently moved, whereas the pressure detection position by the tire ground contact of the accompanying person is continuously. Moving. That is, the passer-by identification information stored in the memory means 5 of the second embodiment includes information indicating intermittent movement of the pressure detection position, and the accompanying object recognition information indicates continuous movement of the pressure detection position. Contains information to indicate. The recognition sensor unit 9 recognizes a passerby when the output of each pressure sensor 10 indicates intermittent movement of the pressure detection position. Further, the recognition sensor unit 9 recognizes an accompanying object when the output of each pressure sensor 10 includes a continuous movement of the pressure detection position. Other configurations are the same as those in the first embodiment.
