- the lower limit of the allowable range is set to zero, and all speed patterns below the upper limit are selected.
- step ST54 speed pattern determination means
- the traveling time W ij—k corresponding to each speed pattern selected in step ST53 is compared with each other, and the speed pattern that minimizes it is selected. .
- the operating efficiency of the elevator can be increased by selecting the speed pattern that minimizes the moving time within the allowable range of the temperature rise.
- the present embodiment also has the following effects. If a high-speed pattern and a low-speed pattern exist in the speed pattern, the conventional example always selects the low-speed pattern when switching to the overload suppression operation. This is because, in general, when comparing a low-speed pattern with a high-speed pattern, the low-speed pattern tends to have a lower temperature value instead of a longer moving time. On the other hand, a high-speed speed pattern has a shorter moving time, so that the total drive input amount is small, and as a result, the temperature value may be kept low. This is particularly noticeable when the travel distance is long. In the conventional example, a low speed pattern is selected even in such a case, but in the present invention, a high speed pattern is selected. Therefore, it is possible to switch the speed pattern appropriately, and it is possible to operate the vehicle while suppressing the temperature rise without unnecessarily lowering the operation efficiency.
- step ST54 the following can be performed.
- the speed for minimizing the evaluation function having the temperature T j and the moving time W ij-k corresponding to each speed pattern Select a degree pattern.

- a speed / ° turn with a short moving time is selected, and when a is made smaller than b, a speed pattern with a small temperature rise is selected.
- this evaluation function can be adjusted according to the time zone and the result of the temperature detector. For example, when the detection value of the temperature detector 3 is close to the allowable upper limit, the evaluation function is adjusted to lower the temperature, and when the temperature margin is large, the evaluation function is adjusted to decrease the moving time. Temperature and operating efficiency can be adjusted according to the time of day. Also, an evaluation function may be set so as to suppress the temperature rise before the time when the number of passengers increases, such as when going to work, and the evaluation function may be set to increase the operation efficiency when going to work. This ft can be expected to reduce congestion and reduce waiting time.
- the combination of the car load and the movement distance is set for all possible values of the ft. It may be reduced by putting together similar elements. As a result, the capacity of the data table is reduced, and the storage capacity of main controller 1 can be reduced.
- the selection of the operation pattern in step ST51 selects the one closest to the gyro load and the moving distance calculated in step ST21.

This is represented, for example, as time-series data as shown in FIG. Note that other configurations are the same as those in FIG. 1, and therefore, reference is made to FIG. 1 and description thereof is omitted here.
- Figure 6 shows the number of passengers (or the number of activations) of the elevator every hour from midnight to the next day's temple as statistical data. Therefore, the time interval is one day. One day is an example, and it is set as appropriate. Such statistical data can be created by summing up elevator operation data. Also, in offices and condominiums, statistical data is often in a fixed form, so it is possible to have only two types of data, one for holidays and one for weekdays.
- main controller 1 has a plurality of (in the figure, q (q is an arbitrary value of 1 or more)) operation mode data tables 20 as shown in FIG.
- a speed pattern (acceleration / deceleration ⁇ *, jerk *, maximum car speed V *) is set for the moving distance L * of the chin and the car load H *. Is set so that the capacity of the electric motor 4 can be used efficiently. For example, when the car load is balanced with the counterweight 7, high acceleration / deceleration, high jerk, and high maximum speed are set, and where the travel distance is long, the maximum speed of the power rod is set large. When the moving distance is short, the acceleration / deceleration is set to be large.
- the operation mode is set according to the elevator's transportation capacity.For example, operation mode 1 is set to high maximum speed, high acceleration / deceleration, and high jerk, and operation mode 2 is 80% of operation mode 1.

- the current time t An appropriate time period from the time zone in which is included is set as the evaluation time section, and the number of passengers (or the number of activations) during that time is arranged in time series. For example, if the current time is 0 o'clock and the evaluation time interval is 3 hours,
- step ST92 candidate extracting means
- step ST93 prediction calculation means
- the column Among the listed combinations the temperature state of the equipment is calculated from the time-series data corresponding to the drive input amount. This is calculated in the same manner as in step ST24 described in the first embodiment.
- step ST94 permissible range confirmation means
- all the combinations of the operation modes in which the temperature state calculated in step ST93 is within the permissible range are selected as candidates. This is performed in the same manner as in step ST53 of the second embodiment.
- step ST95 operation mode determining means
- an operation mode in which the average waiting time (or average traveling time) of the passenger is the smallest among the candidates is determined. This is determined as follows. Assuming that m candidates are selected in step ST94, the time series data of the average waiting time (or the average travel time) corresponding to each of the candidates is ⁇ wa1, wb1, wc1 ⁇ , ' ⁇ , If ⁇ Wam, wbm, wcm ⁇ and "T", the operation mode is determined to be the one with the smallest value among the values Jk (1 ⁇ k ⁇ m) calculated by the following equation 5. :
- J k (P a * wa k + P b * wb k + P c * wc k) / (P a + Pb + P c)
- Operation mode setting is completed when 1 ⁇ ⁇ m or more (step ST96).
- the operation mode is set periodically according to the above steps.
- the time interval for setting this operation mode can be set arbitrarily, but the shorter the time, the higher the temperature estimation accuracy. However, do not make it too short because the amount of calculation increases. For example
- the car speed, acceleration / deceleration, and jerk are selected from the correspondence table in Fig. 7 according to the car load and travel distance, and the elevator is operated.
- the average waiting time or the average traveling time of the passenger within the allowable temperature of the equipment is reduced according to the time zone. Since the operation pattern is appropriately switched, it is possible to operate with high operation efficiency within a range that does not exceed the drivability limit of the component devices.
- the effect is large because the dispersion of statistical data is reduced.
- an operation mode that minimizes the waiting time is selected, reducing passenger frustration.
- the operation pattern is selected so that the waiting time or travel time is reduced in the time section to be evaluated, the total operation efficiency increases.
- the temperature state is estimated using the drive input amount of a predetermined component, but the temperature rise of the predetermined component is calculated in advance for the drive input amount. Or, by using a method such as calculating the temperature rise of the specified components for the number of startups and the number of passengers based on tests with actual equipment, etc., without using the drive input amount, the specified configuration
- the temperature state can be estimated using the temperature rise of the equipment. In this case, the description of the drive input amount in the above description is replaced with the temperature rise amount. This makes it possible to use a cheaper computer.
- the amount of calculation when updating the operation mode can be reduced.
- the operation mode is set at time t0.
- the evaluation time interval is set to 3 units, and time t 0, t
- the operation modes A, B, and C are set by the method of the present embodiment in each time unit separated by 1, t2, and t3. Assuming that the operation mode update section is set to one unit, the update work is performed at time t1, and the time section t1 to t2, t
- Operation modes of 2 to t3 and t3 to t4 are set.
- the operation mode B between times t1 and t2 and the operation mode C between times t2 and t3 selected in the previous update in step ST92 are not changed.
- Operation mode from time t3 to t4 And extract time-series data from the combinations that can take only data.
- the reason for this is that the operation mode B between times t1 and t2 and the operation mode C between times t2 and t3 selected during the previous update satisfy the temperature tolerance while waiting time or This is because the choice was made to reduce the travel time, so even if it was selected without using this method at the time of this update, it is highly likely that it would be selected.
- the number of combinations of time-series data can be reduced. In this example, the number is reduced from nine to three.
- step ST92 If the temperature state calculated from these candidates does not fall within the allowable range, the process returns to step ST92, and the operation mode B between times t1 and t2 and the operation mode B between times t2 and t3 It is only necessary to create a prospect that changes the operation mode C.
- the evaluation time interval when creating the time series data of the operation mode is longer than the update time for resetting the operation mode, when resetting, only the newly added time is used.
- the calculation time can be reduced by using the combinations as candidates.
