Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an elevator operating device used by physically handicapped people.

Conventionally, when the load in an elevator car reaches a predetermined value (full state), new passengers cannot board the elevator even if the car responds to a hall call. Therefore, signs are displayed at the boarding halls indicating that the boarding halls are full, and passengers are encouraged to pass through the boarding halls when they are called. This in-car load is usually detected by a detector installed in the car detecting the weight of people and objects in the car.

On the other hand, in recent years, people with physical disabilities who use wheelchairs (hereinafter referred to as "disabled people") are increasingly sharing elevators with the general public. In this case, since the wheelchair occupies a large floor space compared to its weight, even if the load detector determines that the car is not full and the car is stopped, it is often impossible to actually board the car. As a result, operational efficiency is reduced due to unnecessary car stops. Furthermore, when the traffic volume is slightly heavy, there is almost no opportunity for a disabled person using a wheelchair to board the car, resulting in severe inequity in service.

The present invention is intended to improve the above-mentioned problems, and aims to provide an operating device for an elevator for physically handicapped persons, which eliminates unnecessary stops of the car and improves services for wheelchair users.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In Figure 1, 1 is a landing with elevator entrances and exits for cars 1 to 3, 2 is a general landing button,
3 is a boarding button for people with disabilities, 4 is an alarm device such as a speaker and indicator light, 5 is a car in car No. 1, 6 is an operation panel in the general car, 7 is an operation panel in the car for people with disabilities, and 8 is installed in car 5. A load detector that detects the load inside the car,
9 is a transmission line that connects the car 5 and the machine room; 10 is a transmission line that connects the landing 1 and the machine room; 11 is a management device that is installed in the machine room and is composed of a small computer such as a microcomputer, a minicomputer, etc. As is well known, it is equipped with a central processing unit, a read-only memory, a readable/writable memory, an input/output conversion device, etc. 12 is a motor control device, 13 is a hoisting motor, 14 is a sheave of the hoist driven by the electric motor 13, 15 is a main rope, and 16 is a counterweight.

Note that there is one set of management devices 11 in total, and one set of control devices 1.
2. The electric motor 13, sheave 14, etc. are installed for each machine.

Next, the operation of this embodiment will be explained using FIGS. 2 and 3.

Now, the load setting value A% of the load detector 3 indicates the ratio to the full load, and corresponds to the weight when the room is almost full with general passengers and no wheelchairs are on board.

When a wheelchair user comes to the landing 1 and presses the handicapped hall button 3, the signal is transmitted to the management device 11 through the transmission line 10, and a dedicated hall call is registered as shown in step 20 by the calculation of the computer. be done. (The following operations are also based on computer calculations, but I will not describe each one as it would be complicated.) Here,
In step 21, the load setting value is changed from A% to B%. The value of B% corresponds to the weight when a wheelchair is on board and the vehicle is almost full of general passengers, and B% is a smaller value than A%.

Now, once the dedicated hall call is registered, step 22
The car that is expected to arrive at this call in the shortest time is provisionally assigned. Next, in step 23, the output of the load detector 8 is input to the management device 11 via the transmission line 9, and it is determined whether the load inside the car is below B%. If it is not below B%, the process returns to step 22. A car is temporarily assigned and the load on that car is determined. If there is a car with an in-car load of B% or less, it is permanently allocated to a registered dedicated call in step 24. Then, in step 25, this car is prohibited from being assigned to a hall call other than a dedicated call. The operations of steps 22, 24, and 25 are well known as operations of an assignment-based group control elevator. Assume that the car assigned in this manner is car 5 of car No. 1.

Now, from the management device 11 to the control device 1 of the first machine
2, and the electric motor 13 is driven.
That is, in step 26, the car 5 starts traveling toward the floor where the dedicated call is registered. During the process, it is determined in step 27 whether the car has stopped due to the car call registered on the car operation panels 6 and 7. If the car has stopped due to the car call, passengers can get on and off in step 28, and then in step 29 the load in the car can be stopped. Determine whether it is below B%. At this time, if the number of passengers increases and the load in the car is no more than B%, the management device 11 issues an output to the alarm device 4, and according to step 30, for example, "A person in a wheelchair is waiting on the 〇 floor. Therefore, if you are a member of the general public, please step down a little.'' will be broadcast (a sign may also be used). And the load inside the car is B%
Repeat this until you get the following. When the load in the car becomes less than B%, the car starts traveling again in step 26 toward the floor where the dedicated call has been registered.

When the car 5 arrives at the dedicated call registration floor in step 31, in step 22 the alarm device 4 broadcasts, for example, "Please give priority to those in wheelchairs." When the passenger gets on and off in step 33 and the dedicated car call is registered by the in-car operation panel 7, the car 5 starts running again in step 34 and heads to the floor specified by the dedicated car call. During this process, it is determined in step 35 whether a hall call has occurred, and if a hall call has occurred, it is determined in step 36 whether or not the car load is below B%. If the load in the car is below B%, the car stops at the floor according to step 37. After the passenger gets on and off, it is determined in step 38 whether the load in the car is below B%, and if it is not below B%, an instruction is given to get off the car as described above, and if it is below B%, repeat step 34. The vehicle starts running. Further, in the case of a car call, it is similarly determined in step 40, and if a car call has occurred, the process moves to step 37. If it is determined in step 36 that the car load is not less than B% (there is no room to ride in car 7), the car passes through the hall call in step 41 and arrives at the dedicated car call registration floor in step 42. The same applies when it is determined in step 35 that a hall call has not occurred, and when it is determined in step 40 that a car call has not occurred. Now, when the wheelchair is disembarked in step 43, all operations are completed.

As explained above, in this invention, when a dedicated car call or a dedicated hall call is registered in an elevator that prevents the car from stopping at a hall call when the car load reaches a set value, the above set value is changed. Since the value is changed to a value lower than , it is possible to prevent the car from stopping in vain and to prevent a significant deterioration in service for wheelchair users.
