DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
1 to 4 show the present invention applied to an exit gate device. 1 and 2, an exit gate device (passenger counting device) 1 is provided in a part of an exit passage when an attendee exits in a facility such as an amusement park, for example, and is in a parallel state. It is composed of a plurality of gate bodies 2A, 2B, 2C provided. Each gate main body 2A, 2B, 2C is a passage having a predetermined width, and constitutes a measuring unit 3 through which a person passes. In the figure, an arrow A indicates a predetermined direction in which a passer-by passes through the measurement unit 3.
[0013]
On the side surface of the gate body 2A, there are a flapper 4 that opens and closes, four stay detection sensors (entrance detection sensors) 5 located upstream in the passage direction, and four passage detection sensors 6 located downstream in the passage direction. Is provided. The stay detection sensor 5 and the passage detection sensor 6 together with a corresponding sensor (not shown) provided on the side surface of the gate body 2B facing the gate body 2A, detects passage of a passerby by transmitting and receiving light. is there. Further, the control unit 7 shown in FIG. 3 is provided inside the gate body 2A, and the control unit 7 includes a counting unit 7a that performs counting based on the detection results of the stay detection sensor 5 and the passage detection sensor 6. ing.
[0014]
The flapper 4 rotates in the directions of arrows P1 and P2 about the axis O. When the measurement unit 3 is opened, the tip of the flapper 4 is positioned at P1, and when the measurement unit 3 is closed, the tip of the flapper 4 is positioned at P2. The stay detection sensor 5 detects a passerby who has entered the exit gate device 1 in the direction of the arrow A, and outputs a detection result to the counting unit 7a. The passage detection sensor 6 detects the exit gate device 1 with the arrow A. A passerby passing in the direction is detected, and the detection result is output to the counting unit 7a.
[0015]
A warning indicator lamp 8 is provided at the upper part of the gate body 2A, and an alarm buzzer 9 and a reset button 10 shown in FIG. 3 are provided inside the gate body 2A. The warning indicator lamp 8 is lit to notify the surroundings when a passerby is detected by mistake, and the alarm buzzer 9 emits an alarm sound when a passerby is detected by mistake. It emits and informs the surroundings. The reset button 10 is a means for returning the number of persons regarded as staying to the initial value when the counting unit 7a erroneously counts the number of persons regarded as staying.
[0016]
As shown in FIG. 3, the control unit 7 opens the flapper 4 based on the detection result of the stay detection sensor 5, and closes the flapper 4 based on the detection result of the passage detection sensor 6. When the staying detection sensor 5 detects a person, the counting part 7a of the control part 7 increases the number of persons regarded as staying based on the output by one and detects the passage of the person by the passage detection sensor 5. In addition, the number of persons considered to stay in the measuring unit 3 is reduced by one, and the number of persons considered to have passed is increased by one.
[0017]
Further, when the passage detection sensor 5 and the stay detection sensor 6 detect an unauthorized intruder in the measurement unit 3, the control unit 7 causes the alarm buzzer 9 to sound a warning sound based on the output, and a warning indicator light 8 has a function of lighting up. Further, the control unit 7 has a function of returning the number of persons regarded as staying to the initial value by operating the reset button 10.
[0018]
Next, the implementation of the passing number counting device of the exit gate device 1 having the above configuration will be described.
In the flowchart, N is a variable of the number of persons considered to be staying, M is a variable of the number of persons considered to have passed, and Nmax is an arbitrarily given upper limit value of the number of persons considered to be staying. In the initial state, N and M are set to 0, and an arbitrary value is given to Nmax.
[0019]
When a passer enters the measuring unit 3 of the exit gate device 1, the stay detection sensor 5 performs detection (step 101). Based on the output of the stay detection sensor 5, the counting unit 7a increases the number of persons considered to be staying by one. That is, in the flowchart, 1 is added to N (step 102). In addition, the control unit 7 opens the flapper 4 so that it can pass.
Subsequently, it is determined whether or not the number of persons regarded as staying exceeds an upper limit value of the number of persons regarded as staying arbitrarily (step 103). That is, in the flowchart, if N does not exceed Nmax, the process proceeds to step 104, and if N exceeds Nmax, it is determined that the stay detection sensor 5 has erroneously detected walking back and forth or mischief, N is returned to the initial value 0 (step 108), and the routine proceeds to step 107.
[0020]
When the passerby passes through the measurement unit 3 and the passage detection sensor 6 performs detection (step 104), the counting unit 7a determines whether or not the number of persons regarded as staying is added based on the output. (Step 105). If the number of persons deemed to be staying is added, the number of persons deemed to be staying is subtracted by one, and the number of persons deemed to have passed is added by one (step 106). In addition, the control unit 7 closes the flapper 4 so that the measurement unit 3 cannot pass.
[0021]
When the passerby enters the exit gate device 3 from the reverse direction, the passage detection sensor 6 performs detection and outputs the detection result to the counting unit 7a. However, the counting unit 7a is stagnant. Since there is no number of people considered, do not increase the number of people considered to have passed. That is, in the flowchart, since there is no stay detection (step 101), the process proceeds to step 104, but since there is a passage detection, the process proceeds to step 105. However, since the number N of persons considered to be staying is not added, the process proceeds to step 107 to prevent the number of persons regarded as having passed through from being increased by mistake, and to turn on the warning indicator lamp 8 and alarm. The buzzer 9 emits a warning sound to inform the surroundings of the presence of unauthorized intruders.
[0022]
In addition, when the number of persons deemed to have stayed due to mischief or the like has been increased, the counting unit 7a stays counted when the upper limit value of the number of persons considered to be staying is exceeded. Since the number of people considered to be returned to the initial value, the number of people deemed to have passed is not increased by mistake. That is, in the flowchart, since there is a stay detection (step 101), the process proceeds to step 103. However, since N exceeds the upper limit value Nmax (step 103), the process proceeds to step 108, where N = 0, the process proceeds to step 107, and the number of persons considered to have passed is prevented from being erroneously increased.
[0023]
Furthermore, when a passerby walks back and forth or mischief in the exit gate device 1, the stay detection sensor 5 detects, and based on the output, the number of persons considered to be staying in the counting unit 7a is increased. Operates the reset button 10 to set N = 0, thereby preventing an erroneous increase in the number of persons considered to have passed.
[0024]
As described above, in the present embodiment, the stay detection sensor 5 is provided, and the number of persons considered to be staying in addition to the number of persons considered to have passed through the counting unit 7a is also calculated, and thus is considered to have passed. The number of people can be counted accurately. In addition, when the passer-by walks or mischief in the exit gate device 1 and adds the number of people that the stay detection sensor 5 detects and stays, the reset button 10 is operated. The number of people deemed to have remained from the outside can be reset to the initial value, and the number of people deemed to have passed can be prevented from being increased by mistake. Can do.
[0025]
The counting unit 7a sets an upper limit value of the number of people considered to be staying, so that when the number of people considered to be staying has reached the upper limit value due to walkers walking around or mischief, etc. However, it is possible to return the number of people considered to be staying to the initial value, so it is possible to prevent the number of people considered to have passed by mistake, and to accurately count the number of people deemed to have passed. Can do.
[0026]
In the present embodiment, the case where the present invention is applied to the exit gate device 1 has been described. However, the present invention is not limited to this. Is possible.
In the present embodiment, the four installations of the stay detection sensor 5 and the passage detection sensor 6 are for the purpose of further improving the detection accuracy, and are not limited thereto.
[0027]
In the present embodiment, the reset button 10 is used as a method for returning the number of persons regarded as staying to the initial value. However, the present invention is not limited to this. For example, using the four stay detection sensors 5 to detect the direction of travel in reverse, that is, when the passerby walks back and forth, the counting unit 7a sets the number of persons regarded as staying to the initial value. You may return. In addition, even if the counting unit 7a sets a time for passing between the stay detection sensor 5 and the traffic detection sensor 6, even if the stay detection sensor 5 is detected, the passage detection sensor 6 does not detect within the set time. If so, the number of persons considered to be staying may be returned to the initial value.
[0028]
In the exit gate device 1 described above, an entrance detection sensor may be provided below the gate body 2A, and the flapper 4 may be opened based on the output.
[0029]

Further, based on the output of the passage detection sensor, the number of persons regarded as staying is reduced by one, the number of persons regarded as passing is increased by one, and the increased counting result is output. As a result, in order to increase the number of people who are considered to have passed by the two outputs of the approach detection sensor and the passage detection sensor, it is possible to prevent the number of people considered to have passed through from being increased by mistake. Can be counted.
[0030]
According to the second aspect of the present invention, an upper limit is set for the number of persons regarded as staying in the measurement unit, and when the number of persons regarded as staying exceeds a predetermined number, the control unit Since the number of persons regarded as staying is returned to the initial value and the number of persons regarded as passing is prevented from being increased by mistake, the number of persons regarded as passing can be accurately counted.
