FIG. 3 shows an example of processing for the traffic control gate device 1, but the gate opening / closing processing control unit 6 includes FIG.
Needless to say, the processing function of the traffic control gate device 2 is also provided as shown in FIG.

When the operation of the apparatus is started by turning on the power, it is first determined whether the mode is the automatic mode or the manual mode (S
T1) In the automatic mode, a predetermined process is executed according to a program.

Now, when a pedestrian is passing in the direction of entry of the traffic control gate device 1, the sensor elements 3a and 3b are turned on to output a sensor pulse signal. Here, the gate opening / closing processing control unit 6 takes in the sensor pulse signals output from the sensor elements 3a and 3b (ST2).

Here, the gate opening / closing processing control section 6 includes 3a
When the sensor pulse signals are received in the order of 3b, it is determined that the pedestrian is heading in the entry direction of the traffic control gate device 1 (ST3, entry direction determination means 11), and the counting means 12a counts up by +1 (ST3).

a and 4b are turned on, and their sensor pulse signals are introduced into the gate opening / closing processing control section 6. Here, when receiving the sensor pulse signals in the order of 4b → 4a (ST6), the gate opening / closing processing control unit 6 determines that the vehicle is heading for the traffic control gate device 1 (ST7, exit direction determining means 13). The counting means 12b counts up by +1 (ST8, incoming traffic coefficient coefficient means 14). However, when the sensor pulse signals are received in the order of 4a → 4b, it is determined that the pedestrian is moving away from the traffic control gate device 1 and the counting means 12
b is not counted up by +1 (ST9).

When it is determined in step ST1 that the automatic mode is set, the two counting means 12a, 12a
The count values CNT1 and CNT2 representing the number of passers b are taken in, and the difference X = CNT1−CNT2 of these count values is taken out (ST11, the in / out traffic amount difference calculation means 15), and the count value difference X is positive or negative. It is determined whether or not the duration t of the direction exceeds a predetermined time t1 (ST1).

When the continuation time t does not continue for the predetermined time t1 or more, for example, when the direction changes from the positive direction to the negative direction, the timer time t is set to reset t = 0 (ST14).

As described above, for example, when the continuation time t of the count value difference X in the positive direction continues for a predetermined time t1 or more,
Any of the numerical ranges A1 to
Am (m: an arbitrary natural number, A1>A2>...> Am) is determined (ST15 ₁ , ST15 ₂ ,

Let passersby pass. At this time, for example, an intense check function different from the check function of the traffic control gate device 1 is provided, and when this check function is cleared, the traffic control gate device 2 can pass.

The same processing is performed for passers-by in the outgoing direction, and the passengers exit the area. Therefore, according to the configuration of the above embodiment, the traffic management gate devices 1 and 2
Are provided with two sets of sensor elements at predetermined intervals along the traffic direction on the entry side and the departure direction side of the vehicle, and sensors 3, 4, and 5 for determining the direction of travel are provided. Since the direction of passage of the pedestrian is determined from the output state of the ON operation in chronological order, the direction of passage of the pedestrian can be reliably determined using a very simple configuration.

Also, the number of passers-in in the incoming direction and the number of passers-out in the outgoing direction are measured, and the traffic control gate device 1 is automatically determined based on the difference in the number of passers in the incoming and outgoing directions. 2, the number of entrance gates on the entrance side and the number of exit gates on the exit side are determined, and the entrance gate plates 1a,.
a,.. and the outgoing direction gate plates 1b,..., 2b,... can be greatly reduced, and the burden of monitoring by the observer can be greatly reduced. Even if the number of pedestrians increases, it can respond sufficiently.

In addition, when a pedestrian passes through the toll gate, two or more traffic control gate devices 1 and 2 are installed so that different check functions, for example, checking of the entrance-side traffic control gate device 1 are relatively simple. If a check function is provided to make the check of the traffic control gate devices 2,... Stricter as the vehicle enters the building, strict management of passers-by can be performed.

In the above embodiment, when the duration t of the count value difference X continues for a predetermined time t1 or more, the entry direction of the passage gate is determined based on the count value difference X and a plurality of predetermined numerical ranges. And the number of traffic gates in the outgoing direction is determined. If, for example, the difference in the amount of incoming and outgoing traffic is calculated at an appropriate time period, especially the duration t of the count value difference X continues for a predetermined time t1 or more. There is no need to determine whether or not. (Other Embodiment 1) FIG. 4 is a block diagram showing another embodiment of the traffic control gate switching control device according to the present invention.

In another embodiment, in addition to the function shown in FIG. 1, the passage of each passage gate is made uniform in consideration of the frequency of use of the gate. Specifically, traffic management gate apparatus 1, each passage gates 1 _1, 1 _2, the ingress direction gate plate 1a for each ..., but out direction gate plate 1b and the gate opening and closing drive unit 1c is provided, and each Passage gate 1

[0039] Also with respect to traffic management gate device 2, gate opening and closing detector 2d, ... Gate Open counting means 36 ₁ for counting a gate open signal, ..., and 36 _n, these gates open counting means 36 _1, ..., 36 _n Are arranged in ascending order of the count value, and the sort values corresponding to the rearranged traffic gates 11 ₁ , 12 ₂ ,... Are input / output gate number determination means 27 ₁ , 27 _2. , ... is introduced.

Since the functions of the other components in FIGS. 4 and 5 are the same as those in FIGS. 1 and 2, the description of these components will be omitted. Next, the operation of the above device will be described with reference to FIG.

When the operation of the apparatus is started by turning on the power, first, it is determined whether the mode is the automatic mode or the manual mode (S
T21) If in the automatic mode, predetermined processing is executed according to the program.

At this time, the pedestrian enters the traffic control gate device 1
, The sensor elements 3a and 3b are turned on in time series to output a sensor pulse signal. Here, the gate opening / closing processing control unit 6 includes the sensor elements 3a and 3b.
Captures the sensor pulse signal output from (ST2
2).

Here, the gate opening / closing processing control unit 6 includes 3a
→ When the sensor pulse signals are received in the order of 3b, it is determined that the vehicle is heading for the traffic control gate device 1 (ST23),
The number-of-passing-passengers counting means 12 counts up by +1 (ST24). However, when the sensor pulse signals are received in the order of 3b → 3a, it is determined that the pedestrian is moving away from the traffic control gate device 1 and the incoming traffic number counting means 1 is determined.
2 is not counted up by +1 (ST25).

On the other hand, when a passerby passes between the traffic control gate device 1 and the traffic control gate device 2, the sensor element 4
a and 4b are turned on, and their sensor pulse signals are introduced into the gate opening / closing processing control section 6. Here, when receiving the sensor pulse signal in the order of 4b → 4a (ST26), the gate opening / closing processing control unit 6 determines that the vehicle is heading for the traffic management gate device 1 (ST27), and counts the number of people passing in the leaving area. The means 14 is counted up by +1 (ST28). However, on the contrary, when the sensor pulse signals are received in the order of 4a → 4b, it is determined that the pedestrian is moving away from the traffic control gate device 1, and the counting means 14 does not count up by +1 (ST29).

Therefore, when it is determined in step ST21 that the automatic mode is set, the two counting means 12, 14
Are taken in, and the difference (direction) X = CNT1-CNT2 of these count values is taken out (S
T31), it is determined whether or not the duration t of the count value difference X in the positive or negative direction continues for a predetermined time t1 or more (ST32, ST33). While the count value difference X continues in the positive direction or the negative direction, the time timer counts up every certain time. Conversely, when the count value difference X does not continue for a predetermined time t1 or more, for example, When the direction changes to the negative direction, the timer time t is set to reset t = 0 (ST34).

As described above, for example, when the continuous time t of the count value difference X in the positive direction continues for a predetermined time t1 or more,
Any of the numerical ranges A1 to
Am (m: an arbitrary natural number, A1>A2>...> Am) is determined (ST35 ₁ , ST35 ₂ ,
...), the determination result input and the gate number deciding unit 17 _1, 3
7 ₂ , ...

At this time, the input / output gate number determining means 17 ₁ ,
17 ₂ ,..., The count values corresponding to the traffic gates 1 ₁ , 1 ₂ ,... Rearranged in ascending order of the count value are input from the sort processing means 32, so that the traffic management gate device 1 based on the determination result. relative number Ingress direction and outgoing direction of traffic gates, sorting means passing gate 1 ₁ in descending order from the smallest count value of 32, 1 _2, ... are selected, traffic management gate device corresponding passage gate 1 of 1 The gate opening / closing drive units 1c,... Of ₁ , 1, ₂ ,.

It is to be noted that the traffic management gate device 1 is provided with a simple check function, the traffic management gate device 2 is provided with an intense check function, and the passer is allowed to pass as in the above embodiment.

[0049] Therefore, according to the configuration of the above-described embodiment, in addition to the same effects of FIGS. 1-3, each passage gates 1 _1, 1 _2, ..., 2 _1, 2 _2, ... of examine the traffic amount, the toll gate ₁ 1, 1 _2, ..., 2 _1, 2 _2, the passage gates ₁ 1 ... ascending order of traffic volume of 1 _2, ..., 2
_Since the gate opening / closing drive sections 1c,... Corresponding to ₁ , 2, ₂ ,... Are controlled to be opened, the frequency of use of gate opening / closing can be made uniform, so that maintainability can be improved and troubles such as failures can be reduced.

(Other Embodiment 2) The above embodiment is
In each case, optical sensors were used as the traffic direction determination sensors 3 to 5. However, two sets of weight sensors were installed on the entrance and exit roads of the traffic control gate devices 1 and 2 so that when a pedestrian passed. It may be possible to determine the entry direction or the exit direction with respect to the traffic control gate devices 1 and 2 from the time-series weight detection signal obtained from the weight sensor.

Also, as shown in FIG. 7, a passer carries a wireless ID card 41 in place of the optical sensor which is a sensor for judging the direction of travel, and is used to enter the traffic management gate device 1 when traveling in the direction of traffic and the traffic management. If a weak radio wave ID signal transmitted from the wireless type ID card 41 is received by the ID processing controller 42 when the vehicle passes through the gate device 1 in the outbound direction, the signal is converted into a pulse signal and introduced into the gate opening / closing control unit 6. 3. According to the processing sequence similar to that of FIG. 6, switching control of the traffic gates and uniform use of the traffic gates can be achieved.

As can be said for all the above-mentioned embodiments, one of the entrance gate plate and the exit gate plate has no lock, and the passerby manually opens the non-lock gate plate to open the pass gate. When entering, the traffic control may be such that the gate plate without lock is closed, and then, when the verification result is OK, the other gate plate is unlocked and automatically opened.
