The management gate is closed and locked.

Further, the control means of the control gate controls the opening / closing speed of the control gate in proportion to the moving speed of the person and / or the load of the person. Further, the gate passage confirmation device confirms that a person has passed the management gate. further,
The lighting equipment and the voice device for guidance are turned on and / or announced when the moving speed of a person is a certain value or more.

[0008]

1 is a plan view of an access control system according to the present invention. A management gate 3 is provided at the entrance of the facility 5, and an entrance sensor 12 and a dynamometer 2 are arranged on the entrance side of the management gate 3. In addition, inside the facility 5, the passage sensor 4, the regular lighting 7, the emergency lighting 9, the ITV 11 for monitoring, and the audio device 1
3 and the like, and a regular lighting 6, an emergency lighting 8, an ITV 10 and the like are arranged around the facility 5. Note that the number of these regular lights, emergency lights, ITVs, audio devices, etc. may be appropriately increased or decreased according to the size and structure of the facility 5.

The entrance sensor 12 such as an infrared sensor detects the approach of the person 1 to the entrance of the facility 5, and the dynamometer 2 detects the entrance sensor 1
The load state of the person 1 who passed 2 is detected. Alternatively, a door may be used as the entrance sensor 12, and a person may be detected by manually opening the door. In the present invention, the emergency state of the person 1 is determined based on the load state of the person 1 detected by the dynamometer 2. Therefore, the feature is extracted from the load signal of the dynamometer 2 as shown in FIG.

In FIG. 2, the left and right direction of the load is X,
When the traveling direction is Y and the vertical direction is Z, A is the case where the person 1 walks at a normal speed, B is the case where the person is in a hurry, and C is the case.
Shows the case of running. When the ratio of the peak value K of each Z-direction load in the case of A, B, and C is calculated, it becomes KZA: KZB: KZC≈1: 2: 4. In addition, ZA, ZB, ZC, etc. attached to each K indicate load values of A, B, C in the Z direction, respectively. Similarly, the peak values of the Y-direction load and the X-direction load are KYA: KYB: KYC≈1: 2: 3 KXA: KXB: KXC≈1: 2: 8, respectively.

Further, the time width t during which the load is generated is A,
Among B and C, they are the same in the X, Y, and Z directions, and tA: tB: tC≈4: 2: 1. As described above, since there is a large difference between the peak value of each load and the time width, the normal walking method and the walking method in case of emergency are distinguished from each other.

The peak value of the above load for a person with a standard weight of 60 kg is approximately KZA = 700N, KZB = 1400N, KZC = 28.
00N KYA = 150N, KYB = 300N, KYC = 450
NKXA = 30N, KXB = 60N, KXC = 240N, and the time width is tA = 520 ms, tB = 260 ms, tC = 130 m.
Therefore, the load judgment standard for each direction is set and the peak value of the load in each direction is compared. Further, the same judgment standard is set for the time width.

For example, as the load determination reference value, KZo = 1600 to 2000N in the Z direction and KYo = in the Y direction.
300 to 350 N, KXo = 90 to 100 N in the X direction, and load peak values in the respective directions are KZo and KY.
When it exceeds O, KXo, etc., it is determined that the person has made an emergency drive.

Similarly, as the time width reference value, to = 25
When 0 to 200 msec is set and the time width measured by the dynamometer 2 is to or less, it is determined that there is an emergency drive.
In the above determination, (1) the load peak can be determined only in one of Z, Y, and X directions. (2) The judgment can be made by only one of the judgment of the load peak and the time width t (OR condition).

In particular, when the person 1 has a light weight such as a child, the above-mentioned load peak may cause an erroneous determination.
Erroneous judgment can be avoided by the time width judgment of the above (2). Therefore, in the present invention, it is also possible to judge the emergency situation based only on the above-mentioned time width. In this case, since the above-mentioned time width corresponds to the moving speed of a person, instead of the dynamometer 2, for example, an infrared speed detector or the like. Can be used.

Further, when the peak value K is K <Ko or the time width t is t> to, the control gate 3 is opened at a low normal speed to detect the passage of a person. After the passage is confirmed by the sensor 4, the management gate 3 is closed at a normal speed so as not to be locked. Also,
In the case of K ≧ Ko and t ≦ to, it is judged as an emergency state, the management gate 3 is “opened” at high speed, the passage sensor 4 confirms the passage, and the management gate 3 is quickly closed “closed”. Lock the "open / close" operation.

Further, in case of emergency driving, the emergency illumination lamps 8 and 9 are turned on, and at the same time, the ITV camera is switched to high image quality so that the emergency situation can be clearly recorded. Audio device 1
The reference numeral 3 outputs guidance to the accused person, a warning to the intruder, and other voice information according to the emergency. In addition, FIG.
Although omitted, the automatic notification device will automatically notify the authorities of the above emergency. Further, the telephone for reporting the emergency situation is also installed in the facility 5. FIG. 3 is a flow chart summarizing the operation of the access control system according to the present invention.

[0018]

The present invention has the following effects. (1) Judging whether or not the person is an evacuee in an emergency based on the movement speed and load change of the person. Since it is locked, the evacuees can be protected inside the facility. (2) The speed of the control gate can be increased according to the degree of urgency to promptly accommodate evacuees. (3) In the case of the emergency, the emergency lighting is turned on and, at the same time, the monitor ITV is switched to the high image quality side, so that the situation of the emergency can be clearly recorded. (4) It is possible to announce protection guidance to evacuees. (5) An automatic notification device can automatically notify the occurrence of an emergency.
