Abstract

PURPOSE: To restrict use of elevator and enhance the safety by installing a retina sensor in a call registration device for hall calls and intra-car calls, and feeding the result from retina sensing and judgement to a control device. CONSTITUTION: When there is a retina entry from a retina sensor 1, a machine No. control device 2 checks if the given data is identical to the corresponding data piece in a database in which retinae are registered. If identical, the machine No. control device 2 registers the call and performs a normal operation. If not identical, a monitor board is informed of any trespasser having intruded into the building concerned, along with actuation of a buzzer, etc. The floor at which the trespasser has manipulated is skipped, and in case an intra-car call for the floor is registered, is canceled at one. The building manager checks if there is any abnormality within the building, and if not, he should restitute the operation from the monitor board, and if any abnormality, shunts down the electricity. Because passenger check is conducted by entry of retinae, a high safety is secured.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to elevator security systems.

[0002]

2. Description of the Related Art In a conventional apparatus, a passenger can be restricted to a specific person by using a special key or a magnetic card, and safety in an elevator or a building can be ensured (JP-A-2-282172).

[0003]

In the conventional device, a call is registered by being read by a switch or a magnetic reader combined with the key by a special tool such as a special key or a magnetic card. As a result, it was used as a crime prevention system for elevators and the entire building, limiting passengers.

However, in large-scale buildings, hotels, apartments, etc., the number of types of keys and cards has increased, and the number of people carrying them has also increased, which is inconvenient for people inside and outside the building to always carry. .

It is an object of the present invention to provide a system which can limit the use of elevators and improve safety.

[0006]

As a means for determining the passenger's retina, there is a retina detector for restricting entry into a specific room.

This device is incorporated in a call registration device in a hall or a car, and the result of retina determination is input to the control device to limit passengers and to secure the security of an elevator or a building.

[0008]

The security system for detecting the retina and restricting passengers is possible if the retina sensor directly connected to the call registration device determines whether the retinas match or does not match and inputs the call to the control device based on the match. Become.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a block diagram showing the overall construction of an embodiment of the present invention. Reference numeral 1 is a retina sensor, and 2 is an elevator machine controller. From the retina sensor 1, a signal that the input retina is detected as a licensed person is output to the machine control device 2.

Next, the operation of the elevator machine controller 2 in the embodiment of the present invention will be described with reference to the security operation flowchart of FIG.

(1) First, in step S10, it is checked whether there is an input from the retina sensor. If not, the input is continuously checked. If there is an input, the process proceeds to the next step S20.

(2) Next, in step S20, it is checked whether the retina matches the data in the registered database. If they match, the call is registered (step S30).
Then, normal operation (step S70) is performed. If they do not match, the process moves to the next process (step S40).

(3) In step S40, the presence of an unauthorized intruder in the building is displayed on the monitor panel and an alarm buzzer sounds.

(4) In step S50, the floor operated by the intruder is not stopped, and if the car call for that floor is registered, it is immediately canceled.

(5) In step S60, the manager checks whether there is an abnormality in the building. If there is no abnormality, the monitor panel is operated to return to normal operation. S80).

According to the embodiment of the present invention, since passengers are checked by inputting the retina, high safety can be secured. If there are unauthorized passengers, the elevator service floor can be restricted to prevent crime.

[0018]

According to the present invention, passengers can be checked and limited by inputting the retina, and the safety of the elevator and the entire building is increased.
