Abstract

PROBLEM TO BE SOLVED: To limit use of an elevator so as to improve safety by registering calls by a call registering device for an elevator traveling along a plurality of floors and judgment of voiceprint of passengers. SOLUTION: Whether or not there is input to a voiceprint analyzing device is checked (step 10). In the case of the presence of input, coincidence with the data of a data base with voice print registered is checked (step 20). In the case of coincidence, call registration is performed (step 30), and normal operation is performed (step 70). In the case of discordance, the presence of an unauthorized intruder in a building is displayed on a supervisory panel to give an alarm (step 40). The stop of an elevator on the floor operated by the intruder is inhibited, and in the case of a car call for this floor being registered, this registration is immediately canceled (step 50). In addition, whether or not there is abnormality in the building is checked (step 60). In the case of no abnormality, normal operation is performed, and in the case of abnormality, the elevator is stopped (step 80). Safety can thereby be improved.

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 device, a special key or a magnetic card can be used to limit passengers to a specific person to ensure safety in an elevator or a building.

[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 a large-scale building, hotel, apartment, etc., the number of types of keys and cards has increased, and the number of people carrying it has been large, which has been inconvenient for people inside and outside the building to always carry.

An object of the present invention is to provide a system capable of restricting the use of an elevator and improving safety by the voiceprint of a passenger's voice.

[0006]

[Means for Solving the Problems] As a means for analyzing / determining the voice of a passenger, there is a voiceprint analysis device used by police or the like for investigating the criminal or for identifying the criminal.

This device is incorporated in a call registration device in a hall or a car, and the result of voice analysis is input to a control device and collated, thereby limiting passengers and ensuring security of an elevator or a building.

[0008]

[Operation] With the voiceprint analysis device directly connected to the call registration device,
Security that restricts passengers by inputting / analyzing passenger's voice, inputting the voiceprint data into the control unit, checking the registered voiceprint data, and registering the call when they match The system becomes possible.

[0009]

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 voiceprint analysis device and 2 is an elevator machine controller. From the voiceprint analysis device 1, a data signal obtained by voiceprint analysis of the input voice is output to the machine control device 2.

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

(1) First, in step 10, it is checked whether or not there is an input to the voiceprint analysis device. If not, the input is continuously checked. If there is an input, the next processing (step 20) ).

(2) Next, in step 20, it is checked whether or not the voiceprint matches the data in the registered database. If they match, the call is registered (step 30).
Then, the normal operation (step 70) is performed. If they do not match, the process moves to the next process (step 40).

(3) At step 40, the presence of an unauthorized intruder in the building is displayed on the monitor panel and an alarm buzzer sounds.

(4) In step 50, 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 60, the manager checks whether there is an abnormality in the building. If there is no abnormality, key operation in the manager's room restores normal operation, and if there is an abnormality, the elevator is stopped (step 80).

According to the embodiment of the present invention, since the voiceprint is analyzed by the input of the voice to check the passengers, 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, it is possible to analyze voiceprints by inputting a voice, check passengers, and limit passengers, thereby improving safety of the elevator and the entire building.
