JPS6318284A - Entry/departure managing apparatus for off-limit zone - Google Patents

Abstract

PURPOSE:To assure the managing of entry and departure for an off-limit zone with a compact apparatus, by altering the on-going direction of one gate according to a entry/departure signal. CONSTITUTION:A rotary bar 1 is connected to a gate 2 and turns freely in the on-going direction with the action of a gate driving section 3. The on-going direction is determined according to an indication from a gate on-going direction indicator 4 to disable the reversion. An entry data input unit 5 an a departure data input unit 6 are linked to the gate on-going direction indicator 4 and the gate on-going direction is selected according to the input of an entry data and a departure data by a personal identification card to be indicated to the gate driving section 3. Furthermore, the gate on-going direction indicator 4 is connected to a computer 8 through an interface 7 and input the entry data and the departure data of the personal identification card to the computer 8 to perform a decision on the qualification of entering and leaving persons and a sorting and recording of the data.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a device for controlling access to restricted areas such as radiation facilities, and is particularly suitable for controlling access to restricted areas with a compact device. Regarding access control devices.

[Conventional technology]

Conventional devices include RADIOISOTOPES, 35
, 80-83 (1986), entry and exit restrictions (gates) are performed by raising and lowering bars. However, no consideration is given to ensuring secure entry/exit control, and no consideration is given to making the device more compact.

[Problem that the invention seeks to solve]

In the above conventional technology, the bar is moved up and down by entry/exit signals, but the direction of movement of the bar is not restricted in any way, so unqualified persons can be allowed to enter the area by exit signals, resulting in insufficient access control. there were. Furthermore, if a rotating bar or the like that can restrict the direction of travel is used, two gates will be required, one for entry and one for mountain range, resulting in the problem of increased installation space.

An object of the present invention is to provide a restricted area access control device that is compact and capable of reliably controlling access to a restricted area.

[Means for solving problems]

The above object is achieved by changing the direction of movement of one gate by an in/out signal.

[Effect]

The direction of movement at the gate is determined by the entry/exit signals, so
The outgoing signal cannot enter the area, and two gates are not required.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG. 1 is a rotation bar, 2 is a gate body, 3 is a gate drive unit, 4 is a gate direction indicator, 5 is an entry data input device, 6 is a departure data input device, 7 is an interface, and 8 is a computer.One rotation The bar 1 is connected to the gate 2, and is rotatable in the traveling direction by the action of the gate drive section 3.

The traveling direction is determined by the instruction from the gate traveling direction indicator 4, and reversal is not possible. An entry data input device 5 and a departure data input device 6 are connected to the gate movement direction indicator 4, which selects the gate movement direction in response to the input of the entry data and the departure data, and sends the data to the gate drive unit 3. It is meant to give instructions. Furthermore, the gate progress direction indicator 4 is connected to a computer 8 via an interface 7, and entry data and departure data are input into the computer 8, so that qualifications of people leaving the area can be determined, data can be organized, and records can be made. It has become. Furthermore, the computer 8 is connected to the gate drive unit 3 via the interface 7, and the gate drive unit 3 operates according to instructions from the computer 8. Those who wish to enter the restricted area must register in advance and present a personal identification card (hereinafter referred to as I
(referred to as a D card). When entering the area, this ID card is set in the entry data input device 5. Entry data is sent to the computer 8 through the gate direction indicator 4 and interface 7. The gate movement direction indicator 4 instructs the gate drive unit 3 to rotate the rotary bar 1 in the direction of entry into the restricted area by inputting the entry data. On the other hand, the computer 8 checks the entry data, and if the registration, entry permission period, etc. are appropriate, an instruction to enable driving is sent to the gate drive section 3 via the interface 7.

The rotating bar 1 can be rotated only in the direction of entering the restricted area, and the person entering the restricted area enters the restricted area via this. On the other hand, when leaving the restricted area, the ID card is set in the castle leaving data input device 6.

Using the same procedure as when entering the area, turn the gate direction indicator 4 so that the rotating direction of the rotating bar 1 is in the direction of exiting from the restricted area.
instructions from. After checking the castle departure data by the computer 8, a drive-ready instruction is sent, allowing the vehicle to go to the castle. When entering and leaving the castle, the rotary bar 1 only rotates in the direction of travel for one person, so no one other than the person who has set the ID card can enter the area.

According to this embodiment, since the advancing direction of the gate is determined in accordance with entry and departure, it is possible to prevent unqualified persons from leaving the castle, such as when other people leave the castle during the entrance procedure.

7-Also, the gate direction indicator 4 allows one rotation bar'
- Since the direction of rotation of the -'n can be changed freely, it has the effect of reducing the installation space by serving as both an entry and exit gate.

〔Effect of the invention〕

According to the present invention, since the gate can be used for both entry and exit, the device can be made more compact. Furthermore, since the direction of movement of the gate is determined in accordance with entry and departure, there is an effect that output to the restricted area can be managed reliably.
