Abstract

PURPOSE:To improve elevator operating efficiency by starting a door to close and let a basket go as giving guidance to passengers awaiting at a boarding place to get in the basket, at the time when the total weight of the passengers in the basket reaches a certain set value less than the rated pay load. CONSTITUTION:When a signal from a load detecting device 5 reaches a set value before all passengers waiting at a boarding place get in a basket 2, an operation control portion 1 outputs a signal to a guidance device 7 and also a door closing signal to a door motor control device 3. These signals cause the guidance device 7 to give door closing guidance to the passengers waiting at the boarding place and the door to start closing. When a door safety device turns on while the door is closing, the door opens and closes again. By the door making a complete close, the operation control portion 1 lets an elevator to start moving in response to the basket 2 call from a basket control panel 6. Thus elevator operation efficiency can be improved.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to an elevator control device.

(Conventional technology) Conventionally, when waiting passengers at a landing boarded the car, if the total weight of the passengers in the car exceeded the rated load, a buzzer etc. would sound to notify that the car was full, and the car would be boarded. However, after the passengers were returned to the platform and the total weight of the passengers in the car fell below the rated load, the doors were closed and operation started.
Due to the wasted time, operating efficiency was reduced.

(Problem to be solved by the invention) When waiting passengers board the elevator car and the car becomes full, the buzzer etc. is currently used to notify the car that the car is full. However, there was wasted time when passengers had to return to the platform, reducing the high rate of operation.

An object of the present invention is to solve the above-mentioned problems by closing the door while providing guidance to passengers waiting at the landing who are about to board the car when the total weight of the passengers in the car reaches a certain set value below the rated carrying capacity. An object of the present invention is to provide an elevator control device aimed at increasing the operating efficiency of an elevator by starting the car and starting the car.

[Structure of the Invention] (Means for Solving the Problems) The present invention detects the total weight of passengers in the car using a load detection device, and when the weight reaches a certain set value below the rated carrying load, the load detection device detects the total weight of passengers in the car. This is an elevator control device that guides passengers waiting at a landing to board the elevator, starts closing the door, and causes the car to depart.

(Function) When a waiting passenger gets into the car at the elevator landing, and the load detection device inputs to the control panel that the total weight of the passengers in the car has reached a certain set value that is less than the rated load, the control panel will It outputs door closing guidance and door opening commands, provides door closing guidance to passengers waiting at the landing, starts closing the door, and when the door is completely closed, the car departs.

(Example) The configuration of an example based on the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram of an elevator system according to an embodiment. 1 is an elevator operation control section. 2 is an elevator car, and the car is provided with a door motor control section 3, a door motor 4, an in-car load detection device 5, an in-car operation panel 6, and the like. Further, the landing area is provided with a landing call button 7 and a landing guidance device 8.

The operation of the elevator control device having the above-described configuration will be explained using FIG. 1 and FIG. 2. When a landing call is registered by the landing call button 7, the car responds to the call, arrives at the floor where the landing call was made, and closes the door in response to a door close command output from the operation control unit 1 to the door control unit 3. Open.

When a waiting passenger at the platform gets into the car, the signal outputted from the load detection device 5 to the operation control section 1 increases by the number of passengers.

The operation control unit 1 outputs a door close signal to the door control unit 3 when all the waiting passengers are able to get on the car, and when the door is completely closed, the car responds to the call registered by the car operation panel 6 and closes the car. let them depart.

However, if the signal from the load detection device 5 reaches the set value before all the passengers waiting at the platform board the car, the operation control unit 1
outputs a signal to the guide device 7 and also outputs a door close signal to the door motor control device 3.

Based on the signal, the guidance device 7 guides the passengers waiting at the landing to close the door.
The door begins to close. The door safety device is turned on while the door is closed.
If this happens, open the door and close it again.

When the door closing is completed, the operation control section 1 responds to the car call from the car operation panel 6, and the elevator departs.

As another example, when the output of the load detection device 5 reaches a set value and the door starts to close, the safety of the passengers getting into the car can be ensured by slowing down the speed at which the door is closed than the normal speed.

Also, although this configuration diagram was drawn based on one elevator, the same effect can be obtained when multiple elevators are group-controlled.

[Effects of the Invention] Before the load inside the car reaches the rated load in the elevator, the elevator door starts closing while guiding the waiting passengers at the landing, and the car departs in response to the car call. It is possible to improve driving efficiency by eliminating wasted time such as having to return to the platform because the passengers are full.
