Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an elevator operation control device during a power outage or a disaster such as a fire or an earthquake.

[Conventional technology]

Fig. 2 is a circuit diagram showing a conventional elevator operation control device.
) is applied. Reference numeral 1 denotes a door opening relay, which is energized when closing the elevator car door. 1a is its normally open contact, and 2 is a relay that is energized when the elevator is running (not shown). normally open contact, 3
4 is a door open detection contact that is closed when the elevator car door is opened; 4 is a door closing timed relay that is energized after a predetermined time period after the elevator car door is opened; 4a; is its normally open contact.

Next, the operation will be explained. Elevator yj111!
If a fire breaks out during an elevator, the elevator will stop normal service for safety reasons and the elevator will be forced to return to the evacuation floor. When the elevator stops at the evacuation floor, the door open detection contact 3 is closed in order to open the car door. As a result, a loop of power line L1 - door open detection contact 3 - door closing time relay 4 - power line L2 is formed, so that p door closing time relay 4 is energized, and when a predetermined time period elapses, Contact 4m is closed. When the contact 4a is closed, a loop is formed between the power line L1, the contact 4a, the door closing relay 1, and the power line L3, thereby energizing the door closing relay 1, which closes the elevator car door. will be closed. That is, when a predetermined time period elapses after the elevator car stops at an evacuation floor and the elevator car door opens, the elevator closes the car door regardless of whether there are passengers in the car.

[Problem that the invention seeks to solve]

Conventional elevator operation control devices return to the evacuation floor and close the elevator door after a predetermined period of time has elapsed after opening the elevator door, regardless of whether there are passengers or not. Even if a person collapses inside an elevator car, he or she will not be rescued and will remain trapped inside the elevator car. Tip 9: When the elevator door is closed, people from the outside cannot see that there are people inside the elevator, and as a result, the passengers inside the elevator cannot be rescued.

This invention was made to solve this problem, and when the car returns to the evacuation floor in the event of a disaster, it is possible to display externally whether or not there are passengers in the elevator car, and also to display the presence or absence of passengers in the elevator car. To obtain an operating device for an elevator that keeps the door of the elevator open even when the car stops at an evacuation floor when there are passengers.

[Means for solving problems]

The elevator operating device according to the present invention detects the load of passengers in the elevator car when the elevator stops at an evacuation floor in the event of a disaster, and closes the elevator door when there is a load in the corner of the elevator. It is intended to be left open.

[Effect]

In this invention, when an elevator stops at an evacuation floor in the event of a disaster, the load inside the elevator car is detected, and when the load is detected, the elevator door is left open without closing. Rescue operations for passengers inside the vehicle can be facilitated and ensured.

[Embodiments of the invention]

FIG. 1 shows a circuit opening showing an embodiment of an elevator operation control system according to the present invention, and the same parts as in FIG. 2 are indicated using the same symbols. In FIG. 5a to 5C are disaster detection contacts of a relay (not shown) that is energized in the event of a disaster such as a fire, 5a is a normally closed contact, 5b and 5C are normally open contacts, 6a, 6
b is the contact located on the evacuation floor, 6m is the normally closed contact,
6b is a normally open contact, 7a and 7b are car self-load detection contacts that detect the load in the elevator car, 7a is a normally closed contact that is opened when there is a load, and 7b is a normally closed contact that is closed when there is a load. The normally open contact 8 is a display device that displays to the outside that there are passengers in the elevator car even after a predetermined time period has elapsed when the elevator car stops at an evacuation floor in the event of a disaster.

Next, the operation of the elevator operation control device according to the present invention configured as described above will be explained. In the event of a disaster, the elevator car stops at the evacuation floor.

If there are still passengers in the elevator car even after a predetermined period of time has elapsed since the car door was opened, the car own load detection contact 7a constituting the load detection means is opened.

Along with this, the disaster detection contact 5a and the contact 6a as a car position detection means for detecting the car stop to the evacuation floor are also open, so even if the normally open contact 4a is closed, the relay l is energized. The elevator car door remains open - On the other hand, the car self-load detection contact 7b constituting the load detection means
, a car position contact 6b as a car position detection means for detecting the car position on the evacuation floor, and a disaster detection contact 5C for detecting a disaster.
Since the normally open contact 4b of the door closing time relay is closed, the power supply line L, - normally open contact 7b...normally open contact 6b - normally open contact 5C - normally open contact 4b - display device 8- The loop of the power supply line L8 drives the display device 8 to display to the outside that there are passengers in the car.

〔Effect of the invention〕

As described above, according to the present invention, when an elevator stops at an evacuation floor during a disaster, the presence or absence of passengers in the car is detected, and if there are passengers in the car, the door of the car is left open. If there are still passengers in the car after a predetermined time has elapsed, the system is configured to display a message outside the car, so even if a passenger falls inside the car due to a fire, etc., and is covered in smoke, they will not be left behind. This has the effect of making it easier to rescue passengers inside the car from the outside.
