Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an improvement in an elevator management device equipped with a statistical device.

[Prior art]

In recent years, an elevator has been proposed, for example, in Japanese Patent Laid-Open No. 58-22274, to install a statistical device in an elevator, to collect statistics on the number of passengers on each floor for each time period, and to manage cars in groups based on the statistical results. There is.

However, elevator traffic is clearly different between holidays such as Sundays and holidays and weekdays. Additionally, depending on the building, there are days when traffic is so heavy that it cannot be called a holiday or a weekday, such as Saturday when the building is closed. In order to make statistics on these separately, a large storage capacity for statistics is required. Furthermore, when statistics are made on traffic that appears only once a week, it becomes difficult for the statistics themselves to have stable values.

[Overview of the invention]

This invention improves the above-mentioned problem, and by estimating the traffic volume on a half-day day from the statistical results of weekdays and holidays, it is possible to appropriately manage car operation without collecting statistics on a half-day day. It is an object of the present invention to provide an elevator management device that does the following.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 7.

This embodiment is constructed as shown in FIG.

That is, the traffic volume on weekdays is measured by the measuring means 2 and the traffic volume on holidays is measured by the measuring means 3 from the output of the landing button 1 on each floor. Based on these traffic volumes and the output of the clock 4, the half hour daily traffic volume estimating device 5 calculates the traffic volume for each time period for each floor, calculates the half hour daily traffic volume using the statistical results of weekdays in the morning, In the afternoon, estimates are made using statistical results for holidays. Based on this estimation result, the car allocation means 6 controls car allocation, and the hoisting motor 8
drive the car.

FIG. 2 is a block circuit diagram of the embodiment of FIG. 1.

In the figure, reference numeral 11 denotes a car control device (only one unit is shown) which is composed of a microcomputer (hereinafter referred to as a microcomputer), as shown in, for example, Japanese Patent Laid-Open No. 51-53354, and a central processing unit (hereinafter referred to as a CPU). )
11A, a storage device 11 consisting of a read-only memory (hereinafter referred to as ROM) in which programs and fixed value data are stored and a readable/writeable memory (hereinafter referred to as RAM) in which data such as calculation results is temporarily stored;
B, a transmission device 11C that transmits and receives data, and a conversion device 11D that is connected to the drive control device 7 and converts input and output signal levels. 12 is also composed of a microcomputer, and similarly includes a CPU 12A, a storage device 12B, transmission devices 12C and 12D, a conversion device 12E connected to the hall button 1, and a clock 4.
The group management device 13 is also composed of a microcomputer and is a statistical device having a CPU 13A, a storage device 13B, and a transmission device 13C.

Next, the operation of this embodiment will be explained using the operation flowcharts shown in FIGS. 3 to 7. Note that FIGS. 3 to 5 are based on programs stored in the ROM of the storage device 13B, and FIGS. 6 and 7 are based on programs stored in the ROM of the storage device 12B.

FIG. 3 shows a program that is executed when an interrupt occurs in the CPU 13A of the statistical device 13 at regular intervals. For example, if a 20 millisecond interrupt occurs, the statistics device 13 will cause the group management device 1 to
Sends and receives data to and from the second CPU 12A. The data to be transmitted at this time includes elevator traffic parameters estimated by the statistical device 13 (e.g., car call occurrence rate, predicted value of number of passengers, etc.), and the data to be received includes elevator traffic parameters detected by the group management device 12. There are quantities (for example, number of passengers, number of people getting off the train, etc.). In step 22, the storage device 13B is
Based on the calendar information stored in the ROM, it is determined whether the day is a weekday. If it is a weekday, it is determined in step 23 whether elevator traffic has occurred. If traffic is occurring, step 24 searches for a time zone that includes the current time. In step 25, the traffic volume received from the group management device 12 is added to the statistics of the floor where the traffic occurred during the time period. Step 2
If it is determined in step 3 that no traffic is occurring, subsequent steps 24 and 25 are not executed. If step 2
If it is determined in step 2 that it is not a weekday, it is determined in step 26 whether it is a holiday, and if it is a holiday, steps 27 to 2
In step 9, the amount of traffic that has occurred is added as in the case of weekdays. If it is determined in step 26 that it is not a holiday (half-day), subsequent steps 27 to 29 are not executed. In this way, traffic volume on weekdays and holidays can be
Storage device 13B divided by time zone, floor and direction
stored in RAM.

FIG. 4 is a program for creating elevator traffic parameters.

In step 31, it is determined whether it is the start time of the time slot (the end time of the previous time slot), and if the start time has been reached, it is determined in step 32 whether or not it is a weekday. If it is a weekday, in step 33 the weekday traffic volume stored in the previous time slot is loaded into the CPU 13A in preparation for measuring the traffic volume in the new time slot. For example, a new statistical value (estimated traffic value) is created by weighted averaging the measured traffic volume in the previous time period and the statistical value up to that point. If it is not a weekday, step 34
Determine whether it is a holiday, and if it is a holiday, proceed to step 35.
The holiday traffic volume stored in the previous time period is taken in, and the data is updated using the same procedure as step 33.
In step 36, the statistical value of traffic volume in the time period including the current time is extracted, and based on this, in step 37, elevator traffic parameters are created. These parameters include predicted values such as the car call occurrence rate for each floor direction and the number of passengers for each floor direction. If it is determined in step 31 that it is not the start time of the time period, and if it is determined in step 34 that it is not a holiday (a half-day), steps 32 to 35 are not executed, and in step 36 the traffic volume statistics up to the previous day are calculated. The values are extracted and traffic parameters are created in step 37.

FIG. 5 shows an extraction program for elevator traffic data.

In step 41, it is determined whether it is a weekday, and if it is a weekday, statistical data for the weekday is extracted in step 42. In step 43, it is determined whether it is a half-day, and if it is a half-day, it is determined in step 44 whether it is morning, and if it is morning (including noon), statistical data for weekdays is extracted in step 45. If it is in the afternoon, the statistical data for the holiday is extracted in step 46. If it is determined in step 43 that it is not a half-day (a holiday), statistical data for the holiday is extracted in step 47. In this way, weekday data is used in the morning of a half-day, and holiday data is used in the afternoon of a half-don day.

FIG. 6 is a program showing a procedure for allocating cars to hall calls in the group management device 12.
In addition to allocating cars to hall calls, the group management device 12 performs various processes such as registering and canceling hall calls, distributing cars to standby, etc., but only the assignment of hall calls will be described here.

In step 51, it is determined whether a hall call has occurred, and if a hall call has occurred, in step 52, the evaluation value of each car for that call is calculated. Statistical results are used during this process, and for this part
This is explained in detail in the figure. Next, in step 53, the car with the lowest evaluation value is assigned to the hall call.
In step 54, the assignment signal is sent to the car control device 11 via the transmission devices 12C and 11C.

FIG. 7 shows details of step 52, which is calculated for each car.

First, in step 52A, the time required to respond to the generated hall call, that is, the expected arrival time TYJ, is determined from the current car position and car direction.
Various methods are used for this purpose, but in general, starting from the current car position, the floor travel time is added in order, and if that floor is the floor where the car is scheduled to stop, then
A method of adding a stop time is also adopted. Next, in step 52B, in order to consider the influence on other hall calls by responding to the hall call that is currently assigned and the hall call that has occurred, set the variable CF representing the floor to 1, and set the variable CF representing the floor to 1. The degree EIKYO, which represents the size of , is initially set to zero. Step 52
At step C, it is determined whether floor CF is the top floor or not. If it is not the top floor, it is determined in step 52D whether a hall call is assigned to that floor. If a hall call is assigned, in step 52E, the influence degree EIKYO is set to the direction of the hall call on the floor CF of the time period k that includes that time.
Add the UD statistical value YF _k (CF, UD). this is,
It is a statistical measure of the amount of traffic generated by responding to this hall call.The larger this value is, the more susceptible it is to the influence of car calls.The influence degree EIKYO is increased, and the generated hall call is This makes it difficult to allocate to this basket. and,
Advance one floor CF in step 52F. If it is determined in step 52D that there is no hall call assignment, step 5
2E is not executed, and the step CF is advanced by one in step 52F. After that, return to step 52C, and step 52C-5
Repeat 2F. If the floor CF is determined to be the top floor in step 52C, the degree of influence is determined in step 52G.
Evaluation value by adding estimated arrival time TYJ to EIKYO
Processing ends as HYOKA.

Note that since elevator traffic is very rare in the afternoons of holidays and half-day days, the influence degree EIKYO may be approximated to zero.

〔Effect of the invention〕

As described above, in this invention, the traffic volume of elevator cars is statistically calculated for weekdays and holidays, and the statistical results of weekdays are used in the morning of half-day days, and the statistical results of holidays are used in the afternoon. Appropriate car operation management can be performed without collecting statistics, and storage capacity can be saved by half a day.
