Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security operation control system for preventing crime in an elevator car.

When the doors close, the elevator car becomes a closed room, causing a crime that violates female passengers. In order to protect passengers from this crime, it has been proposed to provide a crime prevention driving mode selection device in the car and operate the car for crime prevention. In this crime prevention driving mode, driving that forcibly stops the car on each floor and opens the door, or restricts the number of passengers who can get into the car to one person, does not respond to the hall call in the middle, and goes straight to the destination floor Done. This crime-prevention driving may be limited to nighttime when crimes are concentrated, but depending on the building, security-driving may be required even during daytime.

The present invention relates to an improvement in such a security operation control system.

2. Description of the Related Art In a conventional security operation control system, a security operation mode selection device is installed in a car and used by female passengers as needed. However, in addition to the inconvenience of having to install special extra equipment in the car,
There was also an inconvenience that use by mischief other than female passengers could not be ruled out.

Problem to be Solved by the Invention An object of the present invention is to provide an elevator security operation control device which guarantees that only a specific passenger selects a security operation mode without setting a security operation mode selection device. It is in.

Means for Solving the Problems The crime prevention operation control device for an elevator of the present invention that achieves the above-mentioned object is provided with a security operation control signal from a normal operation mode in response to a crime prevention operation request signal from a specific car button pressed in a predetermined order. Operation mode switching means for switching the operation mode to the operation mode is provided so that only the passengers informed of the predetermined order can switch to the security operation mode and use the elevator when desired.

Embodiment FIG. 1 shows an embodiment of the present invention. In the figure, 1 is a car button for each floor, 2 is a security request determination circuit, 3 is a secret number determination circuit, 4 is a car position detection device, 5 is a destination registration circuit, and 6 is a timer. The number determination circuit 3 constitutes the operation mode switching circuit 7.

In this embodiment, the secret number is now 4.3.2, and the passenger wants to get into the car on the third floor and go to the fifth floor. It is a crime prevention time zone, and the passenger operates in a crime prevention mode (for example, a driving mode in which the passenger goes straight to the destination floor without responding to a call on the middle floor).
You want to.

Then, when you press the car button on the third floor, signal C is generated,
This is applied to one input of the AND and NAND circuits associated with the car button. An output signal from the timer 6 is applied to another input of the AND circuit and the NAND circuit. The car position detector also generates a signal from terminal 3 which indicates that the car is stopped on the third floor and is applied to the remaining inputs of the AND and NAND circuits. The signal from the output terminal of the AND circuit is applied to a secret number judgment circuit 3, and this circuit is in a secret number judgment preparation state. The passenger then enters the car button indicating the memorized secret number, for example, 4.3.2.
When the signal is pressed, the signals d, c and b are added to the secret number judging circuit. When it is judged that this is a predetermined secret number, the judging circuit 3 generates a signal and switches to the security operation mode. Next, when the passenger presses the car button 5 of the destination floor, a signal e is generated and sent to the destination registration circuit 5 to register the destination floor. The car reaches the destination floor without stopping on the middle floor. If it is not during the security time zone, if you do not press the car button of the same floor number as the boarding floor, or if you do not press the car button corresponding to the secret number, it will not be switched to the crime prevention mode, and normal operation is not performed. Becomes

Instead of the wired logic circuit of the embodiment, programmed elevator control can be used in an elevator control system that performs management control by a computer. FIG. 2 shows a flowchart in that case.

As is clear from the above, according to the present invention, it is not necessary to install the security operation mode selection device, and only the passengers who need the security operation mode are limited, and the operation mode is changed to the security operation mode when the passengers need it. Can be switched. Rather than installing special equipment in the car, the elevator button control system using a computer uses the car button, so that it can be dealt with only by software.

Claims (2)

(57) [Claims] 1. A crime prevention request determination circuit for disabling normal operation in response to a signal from a car button on a floor on which a passenger has boarded and a car position signal from a car position detection device, and connected to the security request determination circuit. When a specific car button is selected and pressed, a secret number judging circuit for judging whether or not the order of pressing the car buttons is a predetermined order is provided. The method is characterized in that the vehicle is switched to a crime prevention mode in which the passenger is selected in response to a signal from the secret number determination circuit indicating that the order is the order, and is prohibited from responding to a hall call other than the registered destination floor. Security operation control device for elevators. 2. The security operation of an elevator according to claim 1, wherein the security request determination circuit includes a timer for setting a security time zone, and the security request determination circuit is enabled only in the security time zone set by the timer. Control device.
