Abstract

PURPOSE:To prevent an unpleasant feeling from occurring to passengers by calculating the number of passengers to get off to a specific floor when the cage of an elevator reaches an object floor, and setting an optimum door opening/closing time. CONSTITUTION:The number of passengers in a cage is calculated by the signal from a load detecting device 11, and reaching floor is calculated by the input signals from a reaching floor detecting device 4 and a floor detecting device 2, while the destination floor call number is calculated by the input signal from a call register button 21 respectively. And an optimum door opening time made into a data base beforehand depending on these data is called from a ROM 23, or an optimum door opening time is produced depending on the input signals and after it is stored in a RAM 24, it is called out to make into a new door opening time. As a result, by setting the door opening time longer than the door opening time depending on the sort of call, an optimum door opening time can be guaranteed to the passengers to get off. Consequently, no unpleasant feeling is given to the passengers without generating a trouble on service.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an improvement in an elevator door opening/closing control device.

(Prior Art) Conventionally, an elevator door opening/closing control device responds to a car call or a hall call, and when the elevator car arrives at the destination floor,
A door opening command is issued to open the door for a certain preset door opening time, and when the door opening time has elapsed, the door opening command is turned off and the door is closed. In this case, when setting the opening time of the two doors, the average The door opening time is set at a certain level, taking into account the boarding and alighting time of passengers.

However, in this type of elevator door opening/closing control device,
The door opened at the same time both when the car was crowded and when it was quiet, so there was no flexibility, and someone had to keep pushing the door open button during busy times.

For example, when the car is almost full and one destination is called
Naturally, there is a difference between a case in which only one passenger is called, and a case in which the car is sparse and the number of destination calls is appropriate for the number of passengers.
The time it takes to get off the train will vary.

(Problem to be Solved by the Invention) Conventionally, after the elevator reaches the destination floor, the doors are opened for a certain period of time set depending on the type of floor call. When getting off the train, the opening time for each door is too short, forcing passengers to press the door opening button, which deteriorates the service and gives them discomfort.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an elevator door opening/closing control device that improves service to customers and does not cause discomfort by providing a door opening time commensurate with the number of passengers getting off the train.

[Structure of the invention]

(Means for solving W, @) In order to achieve the above object, the present invention provides a call registration detection means for detecting whether or not there is a call registration for the landing floor after the elevator car lands on the destination floor. and the door inside the elevator car opened,
When a call registration is detected by a door opening time setting means in which a door opening time is set according to the type of call registration such as a car call or a hall call, and the call registration detection means, a door opening command is outputted and the door is opened. and door opening command means that turns off the door opening command and closes the door when a set time corresponding to the type of call registration at that time set in the door opening time setting means has elapsed, and how many passengers are in the elevator car. A load detection means for detecting the load and the number of destination floor calls detected by the call registration detection means in addition to the load detection means, and the load and the destination floor are recorded in advance or by a learning function after operation. The system is constructed to include means for creating data on the number of calls and the door opening time on the landing floor, using the database to determine the optimum door opening time, and setting it as the door opening time. .

(Function) Therefore, in an elevator door opening/closing control device having such a configuration, when an elevator car lands on a destination floor, it is detected whether there are many or few people getting off to that floor, and if there are many people, The system can provide an optimal door opening/closing time that is longer than the door opening/closing time depending on the type of call and allows all passengers to get off the train without difficulty, improving customer service and significantly reducing discomfort. can be reduced.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows, in block circuit form, an example of the configuration of an elevator door opening/closing control device according to the present invention.

In Fig. 1, 1 is a call registration device, and this call registration device 1 includes types of calls such as call, hall call, hall call for physically disabled, number of calls by type, floor where the call occurs, and direction of the call. It is for remembering. 2 is a floor detection device that detects the current position of the elevator; 3 is a direction selection device that determines the operating direction of the elevator; 4 is a landing detection device;
11 is a load detection device. This load detection device 11 is capable of detecting the load inside the car by detecting the expansion and contraction of vibration-proof rubber sandwiched between the elevator car frame and the floor surface. Further, 5 is a call registration device 1, a floor detection device 2. Direction selection device 32 This is a door opening/closing command generation device that generates a door opening/closing command to the door opening/closing device 10 based on signals output from the landing detection device 4 and the load detection device 11. This door opening/closing command generating device 5 includes a call registration detection section 61 a door opening time setting section 79 a door opening timer part 82 a door opening command section 9. It is composed of a load detection section 12.

Based on the output signals from the call registration device, the 19th floor floor detection device, and the direction selection device 3, the call registration detection section 6 issues a door opening command when there is a car call on the landing floor or a hall call that matches the direction of elevator operation. Since the door opening time setting section 7 outputs a call registration detection signal g to the call registration detection section 9 and outputs a signal corresponding to the type of call registration to the door opening time setting section 7, the door opening time setting section 7 receives the signal g sent from the call registration detection section 6. The time of the door opening timer 8 is set depending on the type of call registration.For example, if the call registration is only a car call, it is 3 seconds, if it is only a hall call, it is 5 seconds, and the timer exists for both car calls and hall calls. In the case of a call for a person with a physical disability, the time is set to 7 seconds, and in the case of a call for a physically handicapped person, the time is set to 10 seconds. The door opening command unit 9 has an implantation detection bag [4
When the landing detection signal d from the door and the call registration detection signal g from the call registration detection section 6 are input, the on command i is output to the door opening timer 8. It is turned on by command i and outputs a door open command to the door opening/closing device lO, and when the door is fully opened, a time count is started based on a full door open detection signal from a door fully open detection device (not shown).
After counting the time set by the door opening time setting section 7, the door opening command is turned off.

Note that although the door opening/closing button on the heel operation panel is not shown in the figure, if it is considered as a type of call registration, it can be treated as included in the call registration device 1.

Additionally, if the hall call button or the door opening button is pressed while the door opening timer 8 is counting the time, a new door opening time is set, and if it is longer than the remaining time of the door opening timer 8, the door opening timer 8 time settings are updated.

Furthermore, the load detection unit 12 receives the signal j from the load detection device 11.
is input, the approximate number of passengers in the car is calculated, and a load detection signal k is output. In this case, the number of passengers is calculated based on the weight of about 65 kg per person, so some error is expected. In addition, the learning unit 13 inputs the number of passengers from the load detection unit 12, the landing floor, type of call, and number of occurrences from the call registration detection unit 6, and also inputs the actual number of passengers based on the answer back signal from the door opening/closing bag [10]. The system inputs the data for the time the door was open, and creates the optimal door-opening time based on this input data. The database unit 14 classifies and stores the optimal door opening times created by the learning unit 13 according to the number of passengers (2), landing floor, call type, and number of occurrences thereof.

In addition to the door opening time setting for each type of call registration, the door opening time setting section 7 uses the optimum door opening time created by the learning section 13, the number of passengers input from the load detection section 12, and the call registration detection section. The door opening time is changed based on the landing floor, type of call, and number of occurrences input from the database section 14.

FIG. 2 shows an example of a configuration in which the functions of each hardware configuration shown in FIG. 1 are processed and implemented by software using a microcomputer. As shown in FIG. 2, signals from a call registration button 21 such as a call button, a hall call button, a call button for physically disabled persons, etc. are sent to an input buffer under the control of a central processing unit (CPU) 22 in a microcomputer 20. 25 and stored in a random access memory (RAM) 24. Floor detection device 2. Signals from the direction selection device 3, landing detection device 4, and load detection device 11 are also stored in the RAM 24. In addition, the door opening/closing device 1 is stored in the read-only memory (ROM) 23 on the condition that there is a call registration for this landing floor after the elevator has landed on the floor.
Data necessary for issuing a door opening command at 0, or outputting a door closing command to the door opening/closing device 10 if no passenger gets on the elevator within a certain period of time after the elevator has landed and the passenger gets off is stored. There is.

Next, the operation of the elevator door opening/closing control device configured as described above will be explained with reference to the flowcharts shown in FIGS. 3 and 4.

When the program is started, it first determines whether or not the elevator has landed on the floor. If it is determined that the elevator has landed on the floor, it determines whether the door is open or not. If the door is open, there is a hall call in the meantime. Determine whether or not. In addition, if the door is not open or there is a hall call while the door is open, it is determined whether there is a call for a physically disabled person, and if there is a call for a physically disabled person, the door opening time is e.g.
Set to 0 seconds. If it is determined in the above that there is no call for a physically handicapped person, it is determined whether there is a hall call or a car call or not, and if there are both a hall call and a car call, the door opening time is set to 7 seconds, for example. Then there was a hall call,
If there is no car call, the door opening time is set to, for example, 5 seconds, and if there is no hall call and there is a car call signal, the door opening time is set to, for example, 3 seconds. In this way, the new data indicating the door opening time set according to the type of call registration is compared with the old data, and if the new data is larger than the value of the old data, that data is rewritten and the new data replaces the old data. If it is smaller than the value, the data will not be rewritten. Then, when the door opening time is set, a door opening command is output, and after all the doors are opened, counting of the door opening time is started, and when the counting ends, the door opening command is turned off and the door is closed.

On the other hand, as mentioned above, if there is no hall call while the door is open, or if there is no hall call or car call, the door open time count starts after all doors are opened, and the door open command is then turned off and the door is closed according to the procedure described above. do.

Note that if the door open button or hall call button is pressed while counting the door open time, a new door open time is set, and the longer one compared to the remaining time currently being counted is set as the new count value.

In addition, in the flowchart of FIG. 4, the number of passengers per basket is calculated based on the signal from the load detection device 11, and the landing floor is determined based on the input signals from the landing detection device 4 and the floor detection device 2. The number of destination floor calls is calculated based on the input signal from 21, and based on these, the optimum door opening time stored in a database is called from the ROM 23, or
The learning function creates an optimal door opening time based on the input signal, stores it in the RAM 24, and then calls it and uses it as a new door opening timer.

As a result, if the door opening time is set to be longer than the door opening time for the above-mentioned call type, it is possible to guarantee the optimal door opening time for passengers getting off the train.

Further, an example of the database structure of the optimal door opening time is shown as a graph in FIG.

Here, the vertical axis shows the number of passengers, the horizontal axis shows the number of destination call registrations, and the time required for one passenger to get off the train is set to, for example, about 1 second. Additionally, this database has different set values for each floor. This is because the frequency of landing is different for each floor. For example, a floor with a lobby or parking lot has more people coming in and out than a floor with offices, tenants, or residences, so the door opening time is longer. There is a need to. The number of passengers per car and the number of destination calls used here are used to predict the number of people getting off the train at the landing floor.

It is desirable to use a learning function to learn this and create more accurate data.

Furthermore, various methods can be considered for the learning function, and a detailed explanation thereof will be omitted here.

It is also possible to apply the present invention to group control elevators.

〔Effect of the invention〕

As described above, according to the present invention, the optimal door opening time is provided based on the number of passengers in the elevator car, the number of registered destination floor calls, and the landing floor, so that all passengers can get off the elevator without difficulty.
Moreover, it is possible to provide an elevator door opening/closing control device that does not interfere with service and does not cause discomfort to customers.
