Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a security operation system for elevators, and in particular, the present invention relates to a crime prevention system for elevators, and in particular, the present invention is directed to a security system for preventing elevators from invading other floors by passengers who are invited to the elevator. This invention relates to an elevator security operation system designed to prevent burglary by remote control from a room.

[Back forging of invention]

In conventional elevator operation control, there is no function that remotely prevents a specific person from getting off the passenger seat. For this reason, high-class condominiums or specific office buildings have a problem in that they cannot prevent uninvited passengers from using the elevators to enter specific floors of the building.

[Purpose of the invention]

It is an object of the present invention to solve the above-mentioned problems in the prior art, and to prevent uninvited passengers from using the elevator to intrude into the car by a monitoring device installed inside the car. Elevator systems that can prevent the above-mentioned intrusions by monitoring the elevators and forcing them to return to a specific floor while temporarily confining them inside the car and making them wait. The purpose is to provide a crime prevention driving method.

[Summary of the invention]

A feature of the present invention is that a TV camera and a microphone are installed in the passenger car.
A monitor TV and speakers are installed in the caretaker's room to monitor the inside of the car, and the caretaker can forcibly call the 9th passenger back to a specific floor by turning on the forced recall switch. The system is such that the opening of the door by operating the open button is disabled and the door is kept on standby at the specific floor until the manager next turns on the normal operation return switch.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG. 1 is a layout diagram of the car monitoring device, and FIG. 2 is a control circuit diagram. In FIG. 1, 1 is a car, 2i-j:
Tenbicamera 2.3 indicates a viewing board, 4 indicates a monitor television, 5 indicates a microphone, and 6 speakers.

Of these, the trembling camera 2 and microphone 5 are attached to the passenger seat 1, and the monitor television 4 and speaker 6 are installed in the manager's room. While the passenger car 1 is carrying passengers and servicing between floors, the manager monitors the condition of the passengers through the control panel 3, monitor television 4, and speaker 6. If the manager determines that the passenger is an uninvited passenger, the manager turns on the forced recall switch SWI in the Figure 2 control circuit.

In Figure 2, P and 'N are power supplies, A is a recall relay,
At-A4 is the contact point, B is the specific floor return relay, 100
is the door opening/closing relay, 1001 to ioo are its contacts, 1
01 is the door close relay, 1011 is its contact, 1021
'j Door opening relay, 102I is its contact. Further, SW2 indicates a normal operation return switch and an open button in the OP car. When the manager turns on the forced recall switch SW1, the P-8WI-A-N circuit is completed, the recall relay 8 heats up, and this relay A is energized. - Self-maintained by A-H circuit. On the other hand, the specific floor return relay B is activated on the path P A2 BN. As a result, if the passenger is driving in the opposite direction to the return to a specific floor, the passenger stops at the nearby floor and returns to the specific floor again without opening the door (this return operation circuit is developed by the present invention). (The specific circuit is omitted as it is not directly related to this.)

Passengers who are forced to return to a specific floor are P-As-
The door opening/closing relay 100 is energized through the path 100-N, and P

0t 1021 Door close relay 1 on route 101-N
01 remains energized, so passengers wait without opening the door. In this case, even if a passenger trapped in the car presses the open button OP in the car, the door opening/closing relay 100 will remain in the energized state of relay contact A3, so the door will open. Never.

If the manager determines that it is okay to remove the trapped passenger from the passenger seat, he or she will turn on the normal operation return switch SWZ. As a result, callback relay A is deenergized, and as relay A is deenergized, side door opening/closing relay 100 is deenergized. relay 10
0 de-energizes, the door closing relay 101 also de-energizes. On the other hand, how many times is the door opening relay 102 activated by the i-paths P-100, -101, -102-N? At this time, the doors of the cars waiting on the specific floor will be opened on the specific floor, and normal operation will then resume.

In this way, according to this embodiment, by turning on the manager's forced recall switch, passengers are not forcibly called back to a specific floor, such as the floor where the manager's room is located, and the door is opened. During the standby state, the door opening relay remains de-energized to make it impossible to open the door even if the open button is pressed inside the car. By installing a relay to restore normal operation, the doors will be opened on a specific floor where passengers are waiting.
A series of control operations are performed automatically.

〔Effect of the invention〕

As explained above, according to the present invention, passengers can be temporarily confined in the car, and normal operation can be resumed at an appropriate time determined by the manager.
It becomes possible to prevent uninvited passengers from attempting to use the elevator to enter a certain floor of a building by simply turning on a switch in the manager's room.
