BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security device for an elevator.

[0002]

2. Description of the Related Art Residential apartments are becoming more and more high-rise due to poor housing conditions, and an elevator system is indispensable in such apartments. On the other hand, due to the recent deterioration in security, crimes in such high-rise apartments, especially for residents returning home late at night, may cause suspicious persons to enter the elevator together and perform robbery or violence. The need for security measures in elevators has been increasing.

[0003]

However, to prevent crimes in the elevator, a monitor camera for photographing the inside of the elevator has been used for the purpose of preventing crime in the elevator. In this case, a television monitor is monitored. It would be useless for crime prevention without humans.However, if security guards who monitor the monitor television at midnight in an apartment house increase the financial burden on residents, there are only a few problems in which buildings are installed. Was.

[0004] As a relatively simple security measure, in the case of late-night driving, measures are taken to stop at each floor so that the suspicious individual does not get on the elevator together for a long time. Even if it stopped, there was little problem that other people were waiting there, and it was not enough security measures.

[0005] The present invention has been made in view of such a conventional problem, and if the suspicious person rides in the elevator car, the elevator cannot be operated. It is an object of the present invention to provide an elevator security device having a high security effect by preventing entry from a floor.

[0006]

According to a first aspect of the present invention, there is provided an elevator security apparatus, wherein a security code input means, a security code data storage means for registering a security code of each elevator user, and a security code input are provided. The security code input by the means is compared with the security code data registered in the security code data storage means, and when a matching security code is found, the elevator responds to the hall call on the floor where the security code is input. Code collating means, passenger number registering means for inputting the number of passengers, passenger number detecting means for detecting the number of passengers in the elevator car,
Number of passengers comparing means for comparing the number of passengers input by the number of passengers registration means with the number of passengers detected by the number of passengers detecting means,
Only when the number of people comparing means outputs a coincidence signal, the elevator operation means for performing a direct operation to the corresponding destination floor in response to the car call is provided.

According to a second aspect of the present invention, in the elevator security device of the first aspect, the number of occupants is determined by pattern recognition from an image photographed by a monitor camera installed in the elevator car, as the occupant number detecting means. It uses a recognition device.

According to a third aspect of the present invention, there is provided the elevator security device of the first aspect, wherein an arithmetic unit for calculating the number of occupants from a load detection signal of a load detector in the elevator car is used as the occupant detection means. is there.

[0009]

In the elevator security device according to the first aspect of the present invention,
For example, when returning home at midnight, a hall call is made from the elevator hall on the entrance floor. In such a case, the user of the building enters his / her personal identification code into the personal identification code input means. To enter. With this, the security code collation means collates the inputted security code with the security code data registered in the security code storage means, and automatically finds a hall call from the entrance floor if matching data can be found, Call the elevator to the entrance floor.

[0010] When the elevator arrives at the elevator hall on the floor where the hall was called, the user enters the number of persons to be boarded by the number of passengers registering means and gets into the elevator car. Is registered by the car call registration means. Then, the number of occupants detecting means detects the number of persons getting into the elevator car, and the number of occupants comparing means compares the number of occupants inputted by the number of occupants registering means with the number of persons detected by the occupant number detecting means. Only when the means outputs the coincidence signal, the elevator operating means responds to the car call and performs the direct operation of the elevator to the corresponding destination floor.

In this way, first, the suspicious person cannot use the elevator freely by the secret code given only to the user of the building, and furthermore, when the legitimate user gets on the elevator, If they get in together, they will not start the elevator because the number of people will not match, prevent them from moving in the elevator car together with suspicious persons, and prevent crimes in closed rooms inside the elevator car. prevent.

According to the second aspect of the present invention, the number of occupants in the elevator car can be accurately determined by using a pattern recognition device that determines the number of occupants by pattern recognition from an image captured by a monitor camera installed in the elevator car. Detect and enhance crime prevention effects.

According to the third aspect of the present invention, the number of occupants in the elevator car is accurately detected by using a calculator for calculating the number of occupants from the load detection signal from the load detector in the elevator car, and the security effect is reduced. Enhance.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a circuit block diagram of a common embodiment of the first and second aspects of the invention. In the drawing, reference numeral 1 denotes a hall call operation panel installed in an elevator hall on each floor, and 2 denotes an elevator on that floor. Hall call button to call, 3
A security code / passenger number registration button for registering a security code assigned to each resident in advance, and for registering the number of people entering the elevator.

4 is an elevator car, 5 is a passenger detection device for detecting the number of passengers having the configuration shown in FIG. 2, 6 is an opening / closing operation of an elevator door from inside the car,
This is an in-car operation panel for performing operations such as registering the destination floor.

Reference numeral 7 denotes a microcomputer, and the hall call operation panel 1 and the car operation panel 6 described above.
And an elevator control device for exchanging various signals with these devices and controlling the operation of the elevator. The elevator control device 7 includes a comparing unit 8, a password collating unit 9, The personal identification number data storage unit 10 in which personal identification number data assigned to each regular resident (which may be house unit or personal unit) living in this building is registered, and operation control of the elevator is performed. An operation control unit 11 includes a door control unit 12 that controls opening and closing of an elevator door.

Reference numeral 13 denotes a user registration device, which newly registers a password of a resident of the building or registers a change of the password in the password data storage unit 10.

As shown in FIG. 2, the above-mentioned occupant detection apparatus 5 includes a monitor camera 14 for photographing the inside of the elevator car 4, and an image processing unit 15 for converting a video signal photographed by the monitor camera 14 into a digital signal. , Image processing unit 1
5, a pattern storage unit 17 in which various patterns of the shape of a human head are registered, and a pattern extracted by the pattern extraction unit 16 in various types in the parameter storage unit 17. And a pattern recognition unit 18 for recognizing a pattern supposed to be a human head, and a person counting unit 19 for counting the number of patterns recognized by the pattern recognition unit 18. The count result of the number counting section 19 is input to the comparing section 8 of the elevator control device 7.

Next, the operation of the elevator security device having the above configuration will be described. This security device can always operate its function in buildings where strict security is required, but in ordinary buildings, it is necessary to manually set the time zone at night, when there is a high risk of crime, or manually manage the timer. Automatically make the function work under. Here, the description will be continued on the assumption that the security function of the present invention is working in a normal building at midnight, for example, from 9:00 pm to 6:00 am.

Based on the flowchart shown in FIG. 3, when a regular resident arriving at the building tries to go up from the entrance hall on the first floor to the floor which is his / her living floor, for example, the eighth floor by using an elevator, Hall operation panel 1 at the entrance hall
And the hall call button 2 is pressed, a hall call signal 20 is sent to the comparison unit 8 of the elevator control device 7, and the operation of the flowchart in FIG. 3 is started.

When an authorized user inputs his / her personal identification number with the personal identification number / passenger registration button 3 (step S1), the personal identification number signal 21 is sent to the personal identification number collating part 9 of the elevator control device 7, Here, the password is collated with the password data registered in the password data storage unit 10 (step S2). If the passwords do not match, the elevator does not respond to the hall call and continues to wait until a proper password is input. However, if the passwords match, the password collating unit 9 outputs a driving command to the operation control unit 11, and the operation control unit 11 supplies a driving control signal 22 to the elevator car 4 to respond to the hall call, and When the elevator car 4 arrives at the entrance floor, the door control unit 12 opens the elevator door, and the resident can get on the elevator car 4 (step S3).

Before getting into the elevator car 4, the resident operates the password / number-of-passengers registration button 3 again to input the number-of-people-to-be-ridden signal 23 to the comparing section 8, and gets into the elevator car (step S4). , S5).

The resident who gets into the elevator car 4 inputs a car call registration signal 24 to the comparison section 8 by pressing a car call button of his / her destination floor, usually a living floor, by the in-car operation panel 6 (step S6). ).

Then, the comparing section 8 receives the passenger number detection signal 25 in the elevator car from the passenger number detection device 5 (step S7), compares the passenger number detection value with the passenger number registration value, and if there is a match, drives. An operation command is given to the control unit 11, and the operation control unit 11 performs a direct operation to the car call registration floor, and when it arrives at the car call registration floor, opens the door and lowers the passenger, and then responds to another hall call. (Steps S8 to S10).

However, in the case where the suspicious person enters the same elevator car 4 after being forcibly registered by the regular resident as having only one rider, but in step S8, the number of riders is detected. Since the value is different from the number of registered passengers and becomes “2”, the comparison unit 8 does not give an operation command to the operation control unit 11 and the door control unit 12, stops the elevator car 4 at the entrance floor, and outputs a door control signal. 26 keeps the door open, preventing suspicious individuals from entering the elevator car with legitimate residents and moving between floors.

As described above, in the elevator security device of this embodiment, the legitimate resident inputs the personal identification number registered for himself and the number of passengers, and the collation of the personal identification number is established, and If the number of passengers does not match, we do not drive with the door of the elevator car open, so the suspicious person is hiding behind the scenes and the regular resident can get into the same elevator immediately after getting into the elevator car To avoid committing a crime.

The present invention is not limited to the above-described embodiment. In particular, the number-of-passengers detecting device 5 in the elevator car 4 may be configured as shown in FIG.
In other words, elevator car 4 and car frame 2 supporting it
7, a load detector 28 for detecting the load of a person riding on the elevator car 4 is provided.
A / D converter 29 converts the load detection signal from
Then, the load value is calculated by the load calculation unit 30, and further, in the number conversion unit 31, the average load per person (for example, 55 k) is calculated from the load value obtained in the load calculation unit 30.
It is also possible to determine the number of passengers in the car by dividing the load value detected by (g is an average load per person), and to output the number of passengers to the comparison unit 8 of the elevator control device 7. Although the calculated number of passengers based on this load detection often does not provide a very precise value, the number of people who use it late at night is usually one person, and the possibility of crimes in elevators is almost always one person. In the case of a single-seater, if it becomes twice as large as a two-seater, the load value will be twice as different, so it can be easily determined. An apparatus for detecting the number of occupants by detecting the load can be employed.

Further, as a occupant detection device, a piezoelectric sheet for outputting a current proportional to the pressure received is provided on almost the entire floor of the elevator car 4, and the magnitude of the current is converted into the number of occupants. It can also be.

In the above embodiment, the security device functioning at midnight has been described. However, the security device may be operated at all times. In addition, since the possibility of a crime is actually high for a hall call from the entrance floor that can be used by anyone, in the above embodiment, the response operation to the hall call from the entrance floor has been described. If it is necessary to improve the security, the same function can be applied to a hall call from any floor where the elevator stops.

[0030]

As described above, according to the first aspect of the present invention,
When a hall call is made from an elevator hall on a certain floor, if the user of the building inputs his / her own personal identification code by means of the personal identification code input means, the personal identification code input by the personal identification code verification means Is compared with the personal identification code data registered in the personal identification code storage means.If matching data can be found, the hall call is registered. Enter the number of people you are trying to get into by entering the number of passengers by means of the passenger number registration means, board the elevator car, and register your destination floor by means of the car call registration means, and the means for detecting the number of passengers will enter the elevator car. The number of occupants detected by the number of occupants input by the occupant number registration means is detected by the occupant number comparing means. Compared with the number of persons to be detected, only when this number comparison means outputs a coincidence signal, the elevator operating means responds to the car call and performs the elevator direct operation to the corresponding destination floor. The security code, which can only be given by the user of the elevator, prevents the suspicious person from using the elevator freely.Furthermore, when a regular user enters the elevator, By not starting the elevator because it does not match, it is possible to prevent moving in the elevator car with a suspicious person beforehand, and to prevent the occurrence of crime in closed rooms inside the elevator car. Can be prevented.

According to the second aspect of the present invention, since the pattern recognition device is used to determine the number of occupants by pattern recognition from an image captured by a monitor camera installed in the elevator car, the number of occupants in the elevator car is used. Can be accurately detected, and the crime prevention effect can be enhanced.

According to the third aspect of the present invention, since the arithmetic unit for determining the number of occupants from the load detection signal from the load detector in the elevator car is used, the number of occupants in the elevator car can be accurately detected. Security effect can be enhanced.
