Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a room entrance management device which is provided at a boundary between a specific area and another area in a building and manages room entrance to the specific area.

[0002]

[Prior Art]

 FIG. 6 shows a well-known entrance management device, which includes a door 1 provided between a specific area and a boundary between other areas, an electric lock 2 provided on the door 1, and an electric lock 2 provided near the door 1. It is composed of a card reader 4 for reading the card 3 distributed to a pre-registered person and a controller (not shown) for unlocking the electric lock 2 based on the reading result of the card reader 4.

[0003]

[Problems to be solved by the device]

 The conventional device reads the card of a person who has been registered in advance, and when the read result matches the registration number of the person who has been registered in advance, the electric lock can be unlocked and the door can be opened. Has become. However, since the electric lock is unlocked by reading the card, in the case of an abnormality such as a fire or an earthquake, it prevents smooth evacuation of people working in a specific area. In addition, when a rescue operation is performed from outside the specific area toward the specific area, inconvenience is likely to occur in the conventional device.

[0004]

[Means for Solving the Problems]

 This invention solves such a conventional problem by connecting the above-mentioned entrance control device with a so-called abnormality detector such as a fire detector or an earthquake detector, and unlocks the electric lock when an abnormality occurs. Configured to facilitate evacuation and rescue activities.

[0005]

[Action]

 When an abnormality is detected, the electric lock provided on the door is unlocked based on the abnormality detection signal.

【Example】

 Example 1. FIG. 1 shows an embodiment of the present invention, and 3 is a card such as an IC card or a magnetic card. A card reader 4 reads the contents recorded on the card. Although a contact type card and a card reader corresponding to the contact type card are illustrated here for convenience, it goes without saying that the IC card can be replaced with a contactless type card and a card reader corresponding thereto. Reference numeral 5 denotes a controller, and here, an OR gate 6 and a control circuit 7 which are functionally necessary are shown as constituent elements. Reference numeral 8 is a fire detector attached to a key point in a specific area, and its detection signal is given to one input end of the OR gate 6. Reference numeral 9 is an earthquake detector installed in the basement of the building or the like, which is a well-known P wave detector or S wave detector. The detection signal of this detector is given to another input terminal of the OR gate 6. In such a configuration, when a detection signal is generated from one or both of the two detectors other than the card 3 and is given to the control circuit 7 via the OR gate 6, the control circuit 7 generates an electric signal. A signal 10 for unlocking the lock 2 is generated, which unlocks the electric lock 2.

Example 2. FIG. 2 shows another embodiment of the present invention, in the case of an earthquake, the electric lock 2 is unlocked when the seismic intensity is equal to or higher than a preset seismic intensity level. Reference numeral 11 is an earthquake detection unit, 12 is a setting means for setting a predetermined seismic intensity scale, and 13 is a comparator for digitally comparing the detection signal detected by the detection unit with the seismic intensity scale set by the setting means 12, which has two inputs. If the values match, the controller 5 is given the same signal 14 as given from the card reader, and the electric lock is unlocked.

Example 3. 3 (a) and 3 (b) show another embodiment of the present invention, in which an indicator 15 is provided in the vicinity of the door 1 to prevent a person who passes through the door from unlocking the electric lock. In the same figure (b), the output 17 of the flicker signal generator 16 and the output 10 of the controller 5 are given to the AND gate 18, and the output is supplied via the current amplifier 19 to the display 15 It is designed to be blinked by giving it to. It should be noted that, for example, if the characters "unlocked" are written on the display device 15, the blinking makes the display easier.

Example 4. FIG. 4 shows still another embodiment of the present invention, in which a fire detector 8-1 to 8-n provided in a specific area for each floor is connected to a controller 5 in a multi-story building or the like. , Which is associated with the electric locks 2-1 to 2-n of the doors of the respective layers, and for example, when the detector 8-1 detects a fire, the electric lock 2-1 that is the most related is unlocked. That is, it enables people in a specific area on the first floor to evacuate. Reference numeral 20 is a circuit for processing the signals generated from the fire detectors arranged in each layer in the order of generation and giving each detection signal to the corresponding electric lock, for example, see Fig. 1 of Japanese Patent Publication No. 4812040. Can be referred to with reference to the circuit shown in FIG.

Example 5. FIG. 5 shows still another embodiment of the present invention, in which outputs 21-1 to 21-n from the controller 5 are given to the memories 23-1 to 23-n of the voice synthesis output device 22, respectively. The voice synthesis output signals 24-1 to 24-n stored in the above are given to the automatic broadcast control device 26 through the gate 25, and the speakers 27-1 to 27-n installed at the key points in the specific area. It was designed to be broadcast all at once. That is, in the case of the signal 21-1, the contents of the memory 23-1 are broadcast. Specifically, the fact that the electric lock 2-1 has been unlocked is broadcast. As the automatic broadcast control device, for example, the one described in Japanese Patent Publication No. 55-5901 can be exemplified.

[0011]

[Effect of the device]

 Since the present invention is configured as described above, it is effective for smoothly performing evacuation and guidance from a specific area and rescue operation to a specific area when an abnormality occurs.
