FIELD OF THE INVENTION This invention relates to elevator door controls.

[0002]

2. Description of the Related Art Elevators, which are vertical transportation means, are increasing year by year. The contents of the buildings to be installed are various, such as hotels, department stores, condominiums, offices and buildings. In addition, it is the current situation that the buildings themselves are becoming taller due to land conditions, and under such circumstances, almost all elevators are installed in buildings on the 4th and 5th floors and above. In terms of usage of buildings, the number of so-called multi-tenant buildings that have multiple offices and shops in the same building is increasing, and the buildings are becoming more intelligent and multi-purpose. ing. In the case of these buildings, the elevator usage status, that is, the number of passengers getting on and off the car is different for each floor depending on each floor, time zone, setting of events, etc. Generally, the elevator automatically closes when the floor door opens on the destination floor in response to a call (hall call or basket call), and passengers get on and off the car, so the door opens for a certain fixed time, and then the door It is supposed to close. Depending on the passengers getting on and off the door, the door opening time for this fixed time may be short.Therefore, the door opening button provided on the operation panel in the car is operated to maintain the door opening operation and the door opening extension button to open the door. I was lengthening the time.

As described above, due to the multipurpose use of buildings, the number of passengers getting on and off the elevator on each floor naturally varies depending on conditions such as time zone and event contents. Particularly in elevators such as department stores, due to the floors and times when passengers get on and off, there is a considerable amount of strain.

However, in general, the opening time of the elevator door is the time when a call is answered by a general customer and the call response by a wheelchair user of an elevator with wheelchair specifications (a landing call and a basket call can be registered only for wheelchair users). Although there is a difference in the door opening time from time to time, the door is usually opened and closed by a preset time. Therefore, for example, when the passengers in the car get off at the same floor all at once from the full state of the car, or on the contrary when many passengers board from the same floor, the set door open time is almost too short. .
In such a case, it is necessary for the passenger to continue operating the door opening button in the car, or to keep operating the mechanical door safety or the like to keep the door open.

[0005]

[Problems to be Solved by the Invention] In office buildings, department stores, etc., passengers use elevators differently for each floor. Also, in multi-purpose buildings, the number of people getting on and off is naturally different depending on the presence or absence of events and the end time during the event.

However, in general, the door opening / closing time is always open / closed at a fixed time regardless of the user's getting on / off status on each floor or the number of call registrations on that floor.
Depending on the boarding / alighting status, you may have to keep the door open by operating the door open button or door safety on the operation panel inside the car, and this operation is always necessary for floors with a lot of boarding / alighting. , It was very annoying to the user. Therefore, it is an object of the present invention to provide an elevator door control device capable of changing the door opening time control for each elevator stop floor.

[0007]

In order to achieve the above object, the present invention provides a car call for each floor in an elevator adapted to serve a customer in response to a call registered in a car and a hall. In addition, a call registration counter that counts the number of hall call registrations, a load change amount detection control unit that detects the change amount of passengers when the car responds to the target floor, and a car landing door opening for each floor. Door opening average time setting control unit that calculates the average value of the door opening time at the time, a door open counter that counts the number of times the door opening switch provided on the operation panel in the car is operated, and a call registration counter from the call registration counter Value, load change amount detection signal from the load change amount detection control unit, door open average time data from the door open average time setting control unit, and door open from the door open counter Providing door control device for an elevator having a door opening time command control unit for automatically setting the door open time at each floor, based on either data or all data of count value. Further, the call registration count value, the load change amount detection signal, the door opening average time data, and the door open count value are weighted and calculated according to their respective importance, and the door opening time on each floor is automatically calculated. Provided is an elevator door control device configured to be set.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a functional block diagram showing a schematic configuration of an elevator door control device of the present invention, which includes an in-car load detection device 1, a car call, a hall call registration button input device 2, an elevator in-car operation panel 3, and a micro. Processor 4 (hereinafter MP
It is called U). The operation panel 3 in the basket has a door opening control setting switch 31 for selecting the door opening time setting control from normal setting or automatic setting method, a door opening switch 32 for instructing the opening of the elevator door, etc. It is configured with a destination floor setting switch that commands the floor, a door closing switch that commands the closing of the door, and the like. The load detection device 1 is installed above or below a car, and detects the load inside the car, that is, the load of passengers. When the elevator car responds to a call and gets on the floor, the minimum load and the door open The load condition at the time of closing and restarting is instructed to the load change amount detection control unit 41 of each floor in the MPU 4, and as a result, the load change amount of each floor is stored each time the floor is landed.

The car call hall call registration button input device 2 inputs the signals of the car call registration button for instructing the destination floor on the in-car operation panel 3 and the hall call registration button provided in each hall, and the MPU 4 described above is input. The input signal is input to the call registration counter 42 for each floor, and the number of call registrations for each floor is stored.
Further, the door opening time counter 43 on each floor in the MPU 4 always counts the door opening time at the time of landing, and the count is sampled for a certain period of time and each floor data is input to the door opening average time setting control unit 44. .

Here, the average door opening time on each floor is calculated based on the input data. Then, the input signal of the door opening switch 32 in the car operation panel 3 is input to the door opening counter 45 on each floor of the MPU 4, and the number of door opening operations by the door opening button is counted. And the load change amount detection signal from each floor load change amount detection control unit 41, the count value from the call registration counter 42 of each floor, the door opening average time data of each floor from the door floor average time setting control unit 44 of each floor, and Each of the count values from the door open counter 45 is input to the door open command weight value calculation control unit 46.
The door open command weight value calculation control unit 46 puts a weight on each input data. For example, regarding the setting of the door opening time in the input data, the highly important data is the detection signal of the load change amount, and the change amount is weighted with a deviation amount of 1, 3, 5 with respect to a certain specified value. If the door opening average time set value is set as the next most important data, the deviation amount of that data is also weighted with 1, 2 and 3 with respect to the preset standard value of the standard door opening time. To do. Similarly, other call registration count values and door open count values are also weighted, and door open command weight values for each floor are calculated from weight value calculation formulas determined from the respective weight values. The calculation result is transferred to the door opening time command control unit 47, the door opening time of each floor is determined, and the optimum door opening time for the floor is automatically set by this.

Next, the operation of the elevator door control device configured as described above will be described. First, the MP of Figure 1
In U4, the door opening control setting switch 31 is switched to the automatic side while the main control program is being executed, and when the flag is detected, the process first proceeds to the load data setting control subroutine of FIG. In order to set the load data index first, the old load detection data is cleared (step S11: each step is hereinafter abbreviated as "S"). Similarly, clear register A (S1
2) Clear the B register (S13).

Next, the elevator car starts decelerating and the door opening start state is checked (S14, S15) (this subroutine will be described in the first floor landing mode). When the door open start is detected in S15, the data of the minimum load amount that changes at the present time is A
Data is transferred to the register and stored in memory (S16). Next, for the call response, when the operation command is turned on (S17), the current realistic load amount data is transferred to the B register and stored (S18). Then, the load detection counter is incremented by 1 (S1
9) In order to compare the data in the A register with the data in the B register, a subtraction process is performed (S20). With this, the amount of change in load from when the car is on the floor and when the car is open to when it is restarted is monitored, and the passenger's entry / exit situation is estimated.

Next, every time the first floor is landed, the average value of the amount of change in the load is taken and this data is transferred to the D register (S2
1). Then, a load detection counter value arbitrarily set after S21 (this counter value is an arbitrarily set count value for calculating the average value of the load change amounts at the time of landing on a certain floor. Check the data from 30 times) Check from 30 or more (S22). If the count value is less than 30, the processing routine from S12 to S21 is repeated. Therefore, when the count value is 30 or more, the load detection counter is once cleared (S23). Then, the average value data of the load change amounts stored in the D register is checked (S24), and if the data value is 5 or more, the load data index 5 is set. If the load data index is 3 or more and less than 5, the load data index is set to 3, and if the load data index is 1 or more and less than 3, the load data index is set to 1.

Next, FIG. 3 shows a door opening time confirmation control subroutine for setting a door opening time data index. First, the landing door open command counter, the A register, and the B register are cleared (S25 to S27). Then, it is checked whether the basket has landed and a door opening command is output (S28). If the door open command is ON
If so, counting of the door opening time starts from this point.

Next, an operation command is issued every time the call is answered and the door is closed. At the time when the operation command is turned on (S29), counting is stopped (S30). This count is not a count of the door opening time of a fixed time according to the control command, but the time from the actual opening of the door to the door opening command to the door closing is counted. Then, the door opening time count data for opening and closing the door is transferred to the A register and stored (S31).
After the memory, the landing door open command counter is incremented by 1 (S3
2) Every time 1 is added, the average value of the door opening time for each floor is calculated, and this data is transferred to the B register and stored in the B register (S33).

Next, it is checked whether the above-mentioned landing door open command counter is 30 or more, and if it is less than that, the processes of S28 to S33 are repeated. Therefore, if the count value is 30 or more (S34), the landing door open command counter is temporarily cleared (S34).
35). Then, the average value data of the door opening time stored in the B register is checked, and if the data value is 3 or more, the door opening time data index 3 is set (S3
6). If it is 2 or more and less than 3, the door opening time data index is set to 2 (S37), and if it is 1 or less, the door opening time data index 1 is set (S38).

Next, FIG. 4 shows a call input count control subroutine for setting the call input count data index. First, as initialization, a call input counter and a call input count timer, which is a count time timer for counting the number of times of call input for a certain period of time, counts timers (S39, S40). Next, the state of hall call registration on each floor is checked (this description takes the first floor as an example) (S41). If 1F hold call registration is ON, the 1F call input counter is incremented by 1 (S42). After the 1F hall call registration is OFF or the 1F call input counter 1 is incremented, the state of the 1F car call registration is checked (S43).

Similar to the above hall call registration, when the car call registration is ON, the 1F call input counter is incremented by 1 (S4
Four). Here, it is checked whether the 1F call input count value is 15 or more (S45). That is, it is detected whether or not the registration of the hall call and the basket call on the first floor from the start of the call input count timer of S40 is operated for 15 times or more. If the 1F call input count value is 15 or more, the counter is once cleared (S46), and the call input count timer data is checked. As a result of the count timer data (S45), the elapsed time until the call input counter reaches 15 is confirmed, and if it is 5 minutes or less (S47), the call input count data index 0.5 is set. Similarly, 0.3 is set as the call input count data index if the time is 10 minutes or less and 0.1 if the time is 15 minutes or less (S50). As a result, a certain number of call inputs is set, and the usage status of the floor is monitored according to how long the number of call inputs is made.

Next, in FIG. 5, each load data index set by the load data index setting subroutine of FIG. 2, the door opening time data index setting subroutine of FIG. 3 and the call input count data index setting subroutine of FIG. The door opening time setting main routine for finally setting the door opening / closing time of each floor from the values of the door opening time data index and the call input count data index is shown.

First, as initialization, the data register and the E, F, G, H, and J registers are cleared. Next, the door opening control setting switch 31 provided on the operation panel 3 in the basket
When turns ON, the index is set in each subroutine. Therefore, the data is transferred to the data register. The load data index is transferred to the E register, the door opening time data index is transferred to the F register, and the call input count data index is transferred to the G register. And take the product in each register,
First, the product of the data of the E register and the data of the F register, that is, the load data index and the door opening time data index is obtained, and the calculation result is transferred to the H register. Next, the product of the data of the H register and the G register, that is, the call input count data exponent is obtained, and the result is transferred to the J register. When the calculation result obtained by the product of each data index is 5 or more, the change in the load during landing is large and the door opening time is long. The result is that the number of call registrations is high, and the door-open time is set to 15 seconds. Similarly, the door opening time is set to 10 seconds and 5 seconds, respectively, according to the calculation result of the mutual indexes.

[0022]

As described above, according to the present invention, it is possible to estimate the user's boarding / alighting situation by the change in the load at the stop floor of the elevator, and to count the number of hall call registrations and car call registrations on each floor.
Then, the average time of the door opening time when the landing door is opened is calculated, the usage status of each stop floor is judged, and the door open time setting can be automatically changed for each stop floor, which is the optimum door opening service for users. Can be provided.
