Abstract

PURPOSE:To decide it by the own will of a waiting passenger at an elevator hall whether or not an elevator cage is to answer to an elevator hall call when an elevator cage is in a state being approximately full of passengers. CONSTITUTION:It is displayed on an elevator hall by a loading state display unit 3 whether or not the number of passengers in an elevator cage satisfies a given condition. When the number of the passengers in the elevator cage satisfies a given condition, a command to temporarily block an answer to a registered elevator hall call is transmitted from the elevator hall side by means of a raising elevator hall call blocking button 6 and a lowering elevator hall call blocking button 7.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator operating system, and more particularly to an elevator operating system that can perform efficient operation control depending on the number of passengers in a car.

0002

2. Description of the Related Art Conventionally, passenger elevators have been equipped with load detectors to prevent passengers from boarding the elevator car with a load exceeding a specified load. Then, when this load detector operates and generates an output (when the total weight of passengers in the car reaches 80% or more of the specified maximum load, the load detector operates differentially and generates an output), it is determined that the car is full. However, the car is prevented from responding to the hall call, and direct operation is performed to the next registered car call floor or reference floor.

However, in such operation control,
There are the following problems. For example, if you respond to a hall call when the total weight of passengers in the car is one or two people short of full capacity, there are many passengers waiting on the floor where the hall call was received, and the elevator car becomes crowded. If it is determined that not everyone will be able to board the elevator car, no one may board the elevator car. In this case, the elevator car will respond to the next hall call, but if no one gets into the elevator car at that floor, and in the same way as above, the elevator car will respond to the next hall call. do. If such operating conditions continue and unnecessary stops are repeated one after another, the amount of passengers transported will decrease compared to the ratio of the number of stops, the operating efficiency of the elevator will decrease, and as a result, the burden on users will be reduced. Service deteriorates.

[0004] Therefore, in order to correct this problem,
An elevator operating device disclosed in Japanese Patent Application Laid-Open No. 61-140478 has been proposed. This is a conventional load detector (which detects when the total weight of passengers in the elevator car is 80% or more of the car's specified maximum carrying load) and a second load detector (which detects when the total weight of passengers in the elevator car is 80% or more of the car's specified maximum load). This is a combination of conditions in which the total weight of passengers in the car is 70% or more of the specified maximum carrying load), and a condition in which the car is 1 to 2 people short of full capacity (the total weight of the passengers in the car is 70% or more of the specified maximum carrying load). % or more 80%
Under these conditions, if the car load status does not change even after responding to a hall call once, the system prevents the car from responding to the next hall call, Direct operation is performed to the car call floor or standard floor.

[0005]

[Problem to be Solved by the Invention] However, in the conventional elevator operating system as disclosed in the above publication, the load condition inside the car does not change even if the car responds once to a hall call under predetermined conditions. In this case, there is one in the elevator car.
Even though there was room for about two people to board, the next call to the boarding area was not answered. In other words, the passengers were passing through the hall where the hall was called, regardless of the intentions of the passengers waiting at the hall. Therefore, even if the car is nearly full due to an emergency, waiting passengers who wish to board the elevator car will not be able to board the elevator car, and the next elevator will respond to this hall call. Customers had to wait for a long time to arrive at the train station, and the service for passengers waiting at the boarding station had deteriorated.

[0006] Therefore, the present invention provides an elevator operation system in which, when the elevator car is nearly full, the passengers waiting at the elevator hall can decide whether or not to make the elevator car respond to a hall call. The purpose is to provide equipment.

[0007]

[Means for Solving the Problems] An elevator operating device according to the present invention includes a loading status display means for displaying the status of the number of passengers in the car at an elevator hall, and a registered number of passengers according to the loading status in the car. The elevator hall includes a hall call response blocking means that can temporarily prevent a response to a hall call from the elevator hall.

[0008]

[Function] In the elevator operating system of the present invention, the state of the number of passengers in the car can be known from the elevator landing via the loading status display means, and the number of passengers in the car can be known from the elevator landing by the landing call response blocking means. This function can temporarily prevent responses to registered hall calls depending on the loading status, so if the car is nearly full, the elevator car can be stopped from boarding to prevent boarding. can be passed through without having to respond to a hall call.

[0009]

[Examples] Examples of the present invention will be described below.

FIG. 1 is a front view showing an elevator landing equipped with an elevator operating device according to an embodiment of the present invention.

In FIG. 1, reference numeral 1 denotes a landing door of an elevator landing, 2 an operation status display that displays the running direction of the elevator and the position of the elevator to waiting passengers at the elevator landing, and 3
A loading status indicator that displays a state in which the total weight of passengers in the car is close to full (Figure 1 shows a case where the total weight of passengers in the car is 60% or more and less than 80% of the specified maximum loading load for the car); 4 is an ascending hall call button for calling a hall in the ascending direction; 5 is a descending hall call button for calling a hall in the descending direction; and 6 is the total weight of the passengers in the elevator car during ascending operation that satisfies the above predetermined conditions. button 7 is registered when the total weight of passengers in the elevator car during descending operation satisfies the above predetermined conditions. This button is for temporarily blocking a response to a descending hall call.

[0012] In an elevator hall having this configuration, when a passenger boards an elevator car that has just arrived at the first floor and the total weight of the passengers in the car reaches 70% of the car's specified maximum carrying load, the loading state is changed. Display 3 lights up. In this case, when the ascending hall call button 4 is pressed on the third floor, an ascending hall call response blocking button 6, which can temporarily prevent a response to a registered hall call, is activated.

[0013] Next, regarding elevators that service the 1st to 5th floors, where such operating operations are performed, 3.
The response operation and blocking operation for a hall call in the ascending direction of the floor will be explained. FIG. 2 is a circuit diagram showing a circuit that temporarily prevents an elevator operating system from responding to a hall call according to an embodiment of the present invention.

In FIG. 2, P and N are power supplies, 3A is an ascending hall call button for calling the ascending direction of the third floor, and 3
B is an ascending hall call response blocking button for temporarily blocking a response to a hall call in the ascending direction of the 3rd floor, and 2F to 4F are the contacts of the relay that detects that the elevator car is on the 2nd to 4th floor. 2F and 4F are normally open contacts, and 3F is a normally closed contact. 30 is an ascending hall call registration detection relay that detects the registration of a hall call in the ascending direction of the third floor, and 30a, 30
b is its normally open contact, 31 is an ascending hall call response prevention command relay that gives a command to temporarily block the response to a hall call in the ascending direction on the third floor, 31a and 31c are its normally open contacts, and 31b is a normally open contact. It is a closed contact. 21a and 41a are normally open contacts of a relay that gives a command to temporarily block a response to a hall call in the ascending direction on the 2nd and 4th floors, respectively, and 32 detects a position one floor ahead of the actual position of the elevator car. 32a is a normally open contact, 33 is a stop command relay that gives a stop command in response to a landing call in the ascending direction on the 3rd floor, 33a is a normally open contact, and 33b is a It is a normally closed contact. 34 is a loading state detection relay that detects that the elevator car is on the 4th floor in the ascending direction with passengers carrying 60% or more and less than 80% of the car's specified maximum carrying load; 34a is its normally closed contact, 40a, 4
0b is a normally open contact for running, 50a and 50b are normally open contacts for detecting the ascending direction, 60a and 60b are normally open contacts for detecting that passengers in the car are 60% or more and less than 80% of the maximum carrying load specified by the car. 70 means that the passengers in the car are 7 of the maximum carrying load specified by the car.
80 is a normally closed contact for detecting 0% or more, and 80 is a normally closed contact for detecting that the passenger in the car is 80% or more of the maximum carrying load specified by the car. Reference numeral 85 indicates an operation measuring device that measures the number of operations of each normally open contact 21a, 31c, and 41a for 2 minutes, and 90 indicates an operation measuring device 85.
This is an output relay that is energized when the number of operations measured by is equal to or greater than a predetermined value (for example, 5 times), 90a is a normally open contact, and 90b is a normally closed contact.

Next, the operation of the elevator operating system having this circuit configuration will be explained. For example, if there is a landing call in the ascending direction on the 3rd floor, and the elevator car is 5th from the 1st floor.
Assume that the car leaves for the floor with 70% of the car's specified maximum carrying load. In such a state, the loading status indicator 3 that displays the number of passengers in the car lights up, so a passenger who is waiting for the elevator car to arrive by pressing the ascending hall call button 4 on the third floor will know that the car is full. You can know in advance that the situation is close. If the waiting passengers on the third floor are to refrain from boarding this elevator car, press the ascending hall call response prevention button 6.
By pressing , service for the third floor hall call is canceled and the elevator car passes through the third floor elevator hall.

[0016]Here, the details of the operation for preventing a response to an ascending hall call on the third floor will be described. When the third floor ascending hall call response prevention button 6 is pressed, the ascending hall call response prevention button 3B closes. At this time, the number of passengers in the car is 70% of the maximum carrying load specified by the car, so the normally open contact 60a is closed, and P
- Ascending hall call response prevention command relay 31 that prevents a response to a hall call in the ascending direction of the third floor is activated by the circuit of - ascending hall call response prevention button 3B - normally open contact 60a - ascending hall call response prevention command relay 31-N. It becomes a self-holding state. When the elevator car arrives from the 1st floor to the 2nd floor, the normally open contact 2F
closes. Also, since the normally open contact 40a for running and the normally open contact 50a for detecting the upward direction are both closed, P-
The circuit of normally open contact 2F - normally open contact 40a - normally open contact 50a - 1st floor advanced position command relay 32 -N energizes the 1st floor advanced position command relay 32 , and the normally open contact 32
a closes. Therefore, the normally open contacts 32a, 30b and the normally closed contacts 80, 90b are both closed, but the normally closed contact 31b is open, so the stop command relay 33 is energized in response to a hall call in the ascending direction on the third floor. First, it is possible to prevent a response to a hall call in the ascending direction on the third floor by operating a hall button.

On the other hand, the elevator car passes the 3rd floor and reaches the 4th floor.
When arriving at the floor, the normally open contact 4F closes, and the normally open contact 50b for detecting the ascending direction and the normally open contact 60b for detecting 60% or more and less than 80% of the specified maximum carrying load of the car are also closed.
The loading state detection relay 34 is activated. As the loading state detection relay 34 is energized, the normally closed contact 34a opens, so the ascending hall call response prevention command relay 31 is deenergized, and the response inhibition command for the third floor ascending hall call is released. Then, the normally closed contact 31b closes due to the deenergization of the ascending hall call response prevention command relay 31. Therefore, even if the elevator car returns to the second floor in the ascending direction, if the ascending hall call response prevention button 3B is not pressed again, the P-normally open contact 32
a - Normally open contact 30b - Normally closed contact 80 - Normally closed contact 90b -
Since the stop command relay 33 is not energized by the normally closed contact 31b-stop command relay 33-N circuit, the elevator will stop at the third floor in response to a stop command in response to a hall call in the ascending direction of the third floor.

[0018] When the elevator car becomes full (80% or more of the car's specified maximum carrying load), the normally closed contact 80 opens and the stop command relay 33 is activated even if a hall call for the third floor in the ascending direction is registered. Since it is not energized, the elevator automatically passes the third floor hall call without responding.

Further, the ascending hall call response prevention button 6 and the descending hall call response prevention button 7, which temporarily prevent responses to hall calls, are also installed on other floors, and the number of times these buttons are operated is A predetermined time (
When the number of times the button is operated within a period of, for example, two minutes, exceeds a predetermined value (for example, five times), the output relay 90 is energized. By energizing the output relay 90, the normally closed contact 90b opens and the normally open contact 90a closes, so that the normal full passage condition is automatically reduced from 80% to 70% of the specified maximum load in the car.

As described above, the elevator operating system of the present embodiment includes a loading status indicator which is a loading status display means for displaying on the elevator hall whether or not the number of passengers in the elevator car satisfies a predetermined condition. 3, a landing call response blocking means capable of giving a command from the elevator landing side to temporarily block responses to registered hall calls when the number of passengers in the car satisfies a predetermined condition; An ascending hall call response prevention button 6 and a descending hall call response prevention button 7;
When a command to temporarily block a response to a hall call in the ascending or descending direction is issued a predetermined number of times (for example, 5 times) or more within a predetermined period of time (for example, 2 minutes), the It is equipped with an operation measuring device 85 and an output relay 90, which are passage condition switching means for appropriately switching the car load condition, which is a passage condition for a call, according to the ascending direction and the descending direction.

That is, the elevator operation system of the present embodiment displays the total weight of the passengers in the car at the elevator hall using the loading status display 3, and also displays the total weight of the passengers in the car under a predetermined condition (for example, the specified car load). 50% or more of the elevator landing), even if there is a hall call, by operating the ascending hall call response prevention button 6 or the descending hall call response prevention button 7, the elevator will be returned from the elevator hall to that hall call. A command can be issued to prevent the response. Furthermore, when the number of operations in response to the command to prevent a response to a hall call within a predetermined time period exceeds a predetermined value, the load condition in the car for passing the car with full passengers is reduced.

[0022] Therefore, the number of passengers in the car can be confirmed from the elevator landing, and if it is better to postpone boarding because the car is nearly full, the waiting passengers can check the number of passengers from the elevator landing at their own discretion. Responses to hall calls can be temporarily blocked, and unnecessary stops of the elevator can be prevented. Furthermore, when such an operation to prevent a response to a hall call is made more than a predetermined number of times within a predetermined period of time, the conditions for a full passage are automatically switched. Therefore, when the elevator car is nearly full, the waiting passengers at the elevator hall can decide on their own will whether or not to have the elevator car respond to a hall call. When the elevator car stops and no one gets on the elevator car, the elevator car passes without stopping, eliminating unnecessary stops.As a result, efficient elevator operation can be maintained, and the elevator car passes through the elevator car without stopping. services for users will be improved. In particular, in this embodiment, if the ascending hall call response prevention button 6 and the descending hall call response prevention button 7 are pressed frequently, the condition for passing through the hall is switched to low load, so that the elevator passes through the hall concerned. Even without pressing the ascending hall call response prevention button 6 and the descending hall call response prevention button 7, response to the elevator hall call can be temporarily inhibited, and the burden on passengers waiting in the hall is reduced.

By the way, in the above embodiment, when the elevator car is nearly full, a case will be explained in which the waiting passengers at the elevator hall decide on their own will whether or not to have the elevator car respond to a hall call. However, even if the elevator car is not crowded and there is enough room to board, if you want to avoid sharing a ride with others, such as when a woman returns home alone late at night, you can change the elevator passage conditions. It can be applied simply by making changes, and can also contribute to crime prevention measures.

[0024]

As explained above, the elevator operation system of the present invention includes a loading status display means and a hall call response blocking means, and the number of passengers in the car is displayed from the elevator hall via the loading status display means. In addition, it is possible to temporarily prevent responses to registered hall calls depending on the loading status in the car using the hall call response blocking means from the elevator hall, thereby preventing the car from being nearly full. In such cases, the elevator car can be allowed to pass without responding to the hall call in order to refrain from boarding the elevator car. Customers can make their own decisions, eliminating unnecessary stops,
Efficient elevator operation can be maintained, and services for elevator users can be improved.
