DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention measures the average time (hereinafter referred to as the average residence time) that a large number of visitors to a facility such as a department store or an exposition stay in the facility. It relates to a measuring device, and can measure an average residence time of a visitor at a specific time period from the start to the end of the entrance or at a specific time that can be substantially recognized as an instant. .

[0002]

2. Description of the Related Art As a measuring device capable of measuring the above average residence time without using human hands, there is, for example, a measuring device described in JP-B-61-7675. This is, as shown in FIG. 9, connected to an entrance / exit detection device (1) provided at the entrance of the facility, a processing device (2) for processing a detection signal from now on, and further connected to the processing device (2). Timer (4) and memory (3). Further, the above-mentioned exit / exit detector (1) includes an exit detector (11) for detecting an exit and an exit detector (12) for detecting an exit.

[0003] When entry / exit to a facility starts, every time an enter / exit person occurs, the enter / exit person detection device (1) detects this and outputs an entrance signal or exit signal. When the first entry signal is generated from the entrance / exit detection device (1), the time at this time (hereinafter, referred to as the entry time) is read from the timer (4) and the time is stored in the memory (3). Thereafter, each time an entry signal is generated, the time is stored in the memory (3) in the order of entry time.

When an exit signal is generated from the entrance / exit detection device (1), the time at which the signal is generated (hereinafter referred to as exit time) is read from the timer (4), and the exit signal corresponding to the exit signal is read. And the time difference ΔT from the entry time of the same-ranked visitor is calculated. Each time a leaving signal is generated, the time difference ΔT of the same-ranked entering / leaving person is calculated, and the time difference ΔT is sequentially accumulated. That is, the entry / exit times of the x-th entry / exiter are respectively (tx)
In the case of (Tx) and (Tx), when the n-th exiting person occurs, "Σ ((Tx)-(tx)): where x is 1 to n" is calculated. Further, the processing device (2) calculates “Σ ((Tx) − (tx)) / n”, thereby obtaining an average residence time, and displaying the average residence time on the display unit (5). .

[0005] However, in the above-mentioned conventional apparatus, the average residence time of all the visitors from the start of the entrance to the specific time is calculated and displayed. Limited average dwell time cannot be seized. If the true average residence time for each time zone is known, the correlation between the average residence time and the sales amount can be examined, and the average residence time can be used more effectively. There is inconvenience that it cannot be used effectively.

[0006] The invention of claim 1 is based on the invention that "an entrance signal is detected when a passer-by at the entrance of the facility is detected and there is a visitor, and an exit signal is sent when there is an exiter." Providing an entry / exit detection device (1) for output, and processing the signal from the entry / exit detection device (1) to measure the average residence time of the resident in the facility. " An object of the present invention is to make it possible to grasp an average residence time at a band or a time or a value close thereto.

[0007]

The technical means of the present invention for solving the above-mentioned problem will be described with reference to FIG. 1. The technical means of the present invention of claim 1 "stores the occurrence time of each entrance signal. Entry time storage means (16), a clock device (22) for measuring a unit time, and the number of occurrences of an exit signal per unit time which is reset each time the clock device (22) finishes measuring the unit time Number of exits measuring means (15) for counting the number of exits, and an entry time of an entry of the same rank as the exit corresponding to the exit signal is read from the entry time storage means (16), and a difference between these entry / exit times is read. Time difference calculating means for calculating (17)

Divided by the number of exits per unit time output by
3), and the output of the dividing means (23) is displayed on the display section (5).
To be displayed on the screen. "

[0008]

The operation of the above technical means will be described with reference to FIGS. As described above, the entrance / exit detection device (1) outputs an entrance signal and an exit signal each time an entrance / exit to the facility occurs, and each time an entrance signal occurs, that is, the time, that is, The entry time is stored in the entry time storage means (16). That is, as shown in FIG.
If there is a second ... visitor, the entrance time t1, t
Are sequentially stored in the entry time storage means (16).

Next, when an exit signal is generated from the entrance / exit detection device (1), the entry time ty of the entry having the same rank as the latest exit y of the exit is stored in the entry time storage means (16).
And the difference between these two times, that is, “individual residence time ΔTy = current time T−entrance time ty” is calculated by the time difference calculating means (17). Further, the calculated ΔTy is cumulatively calculated by the time difference accumulating means (18), whereby the total residence time ΣΔTy of all the persons who have left in the unit time (K) is calculated.

In the present invention, the total residence time per unit time ΣΔTy is calculated by performing the same processing as when the exiting person exits in the order of entry. Since the facility utilization per unit time is not different from the case of leaving randomly, there is no effect on the actual meaning of the residence time at all, assuming that the facilities exit in the order of entry.

Next, the clock device (22) is operated in the unit time (K).
Is completed, the time-out signal is output, and the total residence time ΣΔTy in the unit time output by the time difference accumulating means (18) at this time is calculated by the number of exits per unit time output by the number-of-exiters measuring means (15). The division means (23) executes an operation of dividing by the number of persons n. As a result, the average residence time (ΣΔTy) / n of the person who leaves the unit time is calculated, and this is displayed on the display unit (5). Further, the clock device (22) is reset, and starts measuring the average residence time (ΣΔTy) / n in the next unit time in the same manner as described above.

[0012]

The invention of claim 1 has the following unique effects. The time until the facility is closed is divided by the unit time set in the clock device (22), and the average residence time in the time zone can be measured for each unit time. You can know the average residence time closely related to the sales of department stores.

[0013]

Next, an embodiment of the first aspect of the present invention will be described with reference to the drawings. FIG. 4 shows the invention of claim 1 implemented in a commercial facility such as a department store, and the entrance and exit (B) to the shop (A) are detected at the ceiling of the entrance (B) through the entrance (B). First and second sensors (S1) and (S2)
An entrance / exit detection device (1) is provided. And the passer-by of the entrance (B) is an entrance / exit detection device (1).
When the vehicle crosses the first sensor (S1) → the second sensor (S2) in the order below, the entrance signal is output, and when the vehicle crosses the reverse order, the exit signal is output. It is configured.

The output of the entrance / exit detection device (1) is guided to an apparatus main body (21).
The entrance signal and the exit signal are processed by a microcomputer incorporated therein. Next, a program for processing the entrance / exit signal will be described based on a flowchart shown in FIG. In this embodiment, as shown in FIG. 6, the average residence time is calculated and displayed in units of 30 minutes. . First, the entry order (X) determined by counting the number of entrance signals from the time of opening the store (A) and the exit order similarly determined by counting the number of occurrences of exit signals from the opening of the store. (Y) are each initially set to "1" (see step (61) in the drawing).

[0015] Next, the number of exits (n) within the unit time, which is determined by counting the number of exiters passing through the entrance / exit (B) in the unit time, that is, the number of exit signals exiting from the entrance / exit detection device (1), is represented by " Initially set to "0". In addition, a start time (TZ) necessary for determining whether or not “30 minutes” as a unit time has elapsed is set to the current time T (see the step in the drawing (62)).

[0016] Next, the output of the entrance / exit detection device (1) is monitored, and if an entrance signal is generated from this, the current time T, that is, the entrance corresponding to the entrance signal, is obtained from a timer incorporated in the microcomputer. Admission time T
Is read. Then, the entry time T is stored in the entry time memory tx (see FIG. 6) corresponding to the entry order (X) of the visitor. In this embodiment, the entry time memory t composed of the entry time memory groups t1, t2,.
Is the entry time storage means (1) described in the technical means section.
6). Also, the value of the entry rank (X) is "1".
(See steps (63) to (65) in the drawing).

[0017] Next, after the start of the measurement of the unit time (start time (TZ) in the step (62) in the drawing)
Is set to the current time T) as “3” as a unit time.
It is determined whether "0 minute" has elapsed. That is, the current time T
Is not exceeded (start time (TZ) +30 minutes) (see step (66) in the drawing). If the time of 30 minutes has not elapsed, the process returns to the step (63) of the drawing code for confirming whether or not the entrance signal has been generated. still,
In this embodiment, the current time T is “start time (TZ)
The functional unit in the microcomputer that determines whether or not “+30 minutes” has not been exceeded corresponds to the timepiece device (22) described in the section of the technical means described above.

[0018] On the other hand, when the entrance / exit signal is not output from the entrance / exit detection device (1) when performing the other process,
The step (67) in the drawing for confirming whether or not the exit signal is output from the entrance / exit detection device (1) is executed. When the exit signal is detected, the entry time ty of the person having the same rank as the exit order y of the exit person corresponding to the exit signal is read from the entry time memory t in FIG. The time difference ΔT from the time T is calculated (see steps (67) and (68) in the drawings). still,
The functional unit in the microcomputer that calculates the time difference ΔT is a time difference calculating unit (1) described in the technical means described above.
Corresponds to 7). In addition, every time a leaving signal is generated, the time difference ΔT is accumulated, so that “accumulated time difference S = cumulative time difference S +
The calculation of “time difference ΔT”, the calculation of “n = n + 1” for calculating the number of exits within a unit time, and the calculation of “y = y” for calculating the total exit order (order from the opening of the store) of the final exiters
+1 "is performed ((69), (70)
Steps). In this embodiment, the functional unit in the microcomputer that executes the operation of “cumulative time difference S = cumulative time difference S + time difference ΔT” corresponds to the time difference accumulating means (18) described in the technical means described above. At the same time, a functional unit in the microcomputer which executes the calculation of the number of exits "n = n + 1" per unit time corresponds to the exit rank measuring means (25). Thereafter, the process proceeds to a step (66) of the drawing for judging whether or not 30 minutes have elapsed from the measurement of the unit time. If 30 minutes as a unit time have elapsed when the step of the drawing code (66) is executed, the value of the accumulated time difference S at that time is divided by the number n of exiting persons in the unit time. Thus, the operation of calculating the average residence time H in that time zone is executed, and the functional unit in the microcomputer that executes the operation is provided to the dividing means (23) described in the technical means section. Corresponding. Thereafter, the value of the average residence time H is displayed on the display unit (5), and the process returns to the operation of resetting the number n of exits within a unit time shown in FIG.

<< Regarding the Invention of Claim 2 >> The invention of claim 2 relates to an improved invention of the invention of claim 1. That is, according to the first aspect, the average staying time of the exiting unit in the unit time that has elapsed has been calculated, so that the average staying time in the next unit time cannot be sufficiently grasped. Therefore, when the sales amount or the like in the next unit time is predicted with the average residence time, a large error may occur in some cases. Another object of the present invention is to make it possible to estimate the average residence time in the next unit time.

The technical means according to the second aspect of the present invention for solving the above problem will be described with reference to FIG. 2. The technical means is as follows: "The last exiting person at the end of the unit time and a certain time before this. A leaving rate increase means (34) for calculating the leaving rate increase rate E by dividing the rank difference of the leaving persons by the fixed time.
And a visitor increase rate calculating means (35) for calculating an increase rate D of the visitors by dividing a difference between the ranks of the two visitors having the same rank as the two exiters and the difference in the entrance times of these visitors. And a correction coefficient for calculating the ratio between the two by dividing the increase rate D of the visitors calculated by the entrance increase rate calculation means (35) by the increase rate E of the exit persons calculated by the exit increase rate calculation means (34). A calculating means (36), and a product of the calculation result of the correction coefficient calculating means (36) and the calculation result of the dividing means (23) in claim 1 is displayed on a display section (5). " It is.

[0021]

[Operation and Effect] The operation and effect of the above technical means will be described with reference to FIGS. The calculation of the average residence time in the unit time at the end of the unit time by the dividing means (23) has been described in the operation of claim 1.
As can be seen from FIG. 3 in which the number-of-entries graph F and the number-of-exits graph G are cut out, points Oy and On representing the first and last exits per unit time and points indicating the visitors having the same rank as these. The area enclosed by Iy and Ih is the accumulated time difference S obtained by summing each staying time of the exiting person in the unit time, and a value obtained by dividing the accumulated time difference S by the number of exiting persons (y-h) in the unit time elapses. It becomes the average residence time H of the unit time.

As shown in the graphs F and G in FIG. 3 showing the number of entrances and exits, the final exit O at the end of the unit time.
The larger the rate of increase (dF / dt) of the number of visitors at the entry time ty of the same-ranked passenger Iy, the larger the horizontal distance between the number of visitors graph F and the number of exits graph G in the next unit time. The average residence time increases with the increase. That is, it can be estimated that the greater the gradient of the tangent line A in the figure, the longer the horizontal distance between the number-of-entry graph F and the number-of-exit graph G in the next unit time, and the average residence time proportional to the horizontal distance increases. .
Therefore, in order to determine the tendency of the visitors, the rate of increase in the number of visitors is calculated by the means for calculating the rate of increase in the number of visitors (35).

Further, as the rate of increase (dG / dt) of the number-of-leaves graph G at the end of the unit time (point Oy), the average residence time in the next unit time becomes shorter.
In other words, it can be predicted that the greater the gradient of the tangent line B in FIG. 3 is, the shorter the horizontal distance between the entering / leaving person graph F and the leaving number graph G in the next unit time is. Therefore, in order to determine the tendency of the exiting persons, the exit increasing rate calculation means (34) calculates the increase rate of the number of exiting persons.

Then, the entrance increase rate calculating means (35)
Is calculated by dividing the increase rate D of the number of visitors calculated by the above by the increase rate E of the number of exits calculated by the leaving rate calculating means (34) to calculate the change rate (D / E). )
Runs. Then, the rate of change (D / E) of the correction coefficient calculating means (36) indicates the change tendency of the residence time at the present time, and the (D / E) is calculated as the residence time (D / E) indicated by the output of the dividing means (23). The value multiplied by the elapsed time in the unit time elapsed, that is, the estimated value of the average residence time in the next unit time is displayed on the display unit (5). As a result, the average residence time in the next unit time can be predicted.

[0025]

Next, an embodiment of the second aspect of the present invention will be described with reference to the drawings. Also in the embodiment of the second aspect of the invention, the installation mode of each device is configured as shown in FIG. Also, as shown in FIG. 6, the unit time is set to 30 minutes, and the average residence time in the next unit time is calculated from the data of the visitors in the unit time.

For this reason, a processing program having the contents shown in the flowchart of FIG. 7 is stored in the microcomputer of the apparatus main body (21). Hereinafter, the processing operation of the apparatus of this embodiment will be described with reference to FIG. I do. When the processing operation is started, the entry rank (X) and the exit rank (y) are set to "1" in the same manner as in the embodiment of the above-described claim 1, and are used when calculating the increase rate E of the exiters. Set the initial exiting rank (h) to "0" (drawing code (82)
Steps). Then, for 30 minutes as a unit time, while performing substantially the same processing as the above-described claim 1,
After executing the step (89) in the drawing for calculating “cumulative time difference S = cumulative time difference S + time difference ΔT”, the exit time of the exiting person corresponding to the exit signal generated is stored in a specific memory Ty of the exit time memory T. Memorize (drawing code (9
See step 0)). Here, the specific memory Ty
Is a memory corresponding to the exit order of the last exited person counted after the store (A) is opened.

After a lapse of 30 minutes as a unit time, an operation for calculating an increase rate D of the visitors is performed in a step (92) in the drawing. That is, the difference between the leaving rank (y) at the time when the unit time has elapsed and the initial leaving rank (h) at the beginning of the unit time, that is, the number of leaving players in the unit time, is calculated. Entry time difference between the entry times (stored in the entry time memory t at the step of the drawing code (84)) of the two visitors of the exit order (y) and the initial exit order (h). -Initial entry time th "is obtained, and the former number of visitors is divided by the latter difference in entry time. That is, the rate of increase in the number of visitors D =
"(Leaving order (y) -initial leaving order (h)) / (entry time ty-initial entry time th)" is calculated.
Incidentally, the rate of increase D of the visitors is represented by a tangent line A (see FIG. 3) of the visitor graph (F) at the entry time ty of the same rank as the final leaving order (y) in the unit time. It is inclined. The functional unit in the microcomputer that calculates the entrance increase rate D corresponds to the entrance increase rate calculation means (35) described in the section of the technical means described above.

The exit time Ty of the final player and the exit time Th of the exiter in the initial exit rank (h) in the unit time.
From the exit time memory T. Then, the time difference and the ratio of the number of exits in the unit time described above, "(exit order (y) -initial exit order (h)) / (exit time memory Ty-initial exit time Th)" are calculated. , Thereby, the number G of exited persons when the last exited person exits the graph G
Is calculated as a slope of the tangent B (see FIG. 3) (see step (93) in the drawing). Then, in the same way as in the first embodiment, the ratio of the entrance increase rate D and the exit rate E, that is, "cumulative time difference S / number of exits n per unit time" calculated by the dividing means (23), that is, " Multiply by the rate of increase in entrance D / the rate of increase in exit E, and the value is displayed on the display unit (5) as the average residence time H per unit time. In this embodiment, the function corresponds to the entrance increase rate calculating means (35) described in the section of technical means or the technical means for calculating the exit rate E.
The functional unit in the microcomputer that executes the calculation of “increase in entrance rate D / increase in exit rate E” corresponds to the correction coefficient calculation means (36) described in the section of technical means. Thereby, the average residence time in the next unit time can be predicted and displayed.
