Then, when it is determined that the risk of damage is high, the car stop position that minimizes the risk of damage is calculated. Here, the damage risk is an index indicating the possibility of damage to the elevator from arbitrary time to the future. Therefore, the damage risk is calculated according to the predicted weather change at the location where the elevator is installed. As an example, it is calculated based on the weather information data of the elevator installation position at an arbitrary time and the predicted value of future weather information data of the elevator installation position based on the nearby weather information data. Also, the damage risk may be calculated using the degree of impact, or may be a value set in advance based on these. Furthermore, in the present embodiment, a car stop position at which the damage risk is equal to or less than a predetermined threshold value (damage risk reference value or damage risk reference value for specifying a retreat position) may be obtained. It should be noted that the arbitrary time is preferably the time when this processing is performed, that is, the present time.

The operation control command unit 35 also outputs a command for operating and controlling the car of the elevator 1 to the car stop position at which the damage risk determined by the determination processing unit 34 is minimized.

The nearby weather information data table 371 stores the weather information data of the nearby area shown in FIGS. That is, the wind speed W _x , wind direction D _x , amount of precipitation R _x , and atmospheric pressure P _x are stored for each neighboring area (e to nw).

Further, in this embodiment, each floor (1F to 10F) is used as the evacuation position candidate (j), but the middle of the floor may be used, and the evacuation position candidate (j) is not limited to the floor.

Also, the damage risk reference value table 376 stores the damage risk reference value C _L and the damage risk reference value C _Lj for specifying the evacuation position as described above. In this table, the damage risk reference value C _L and the damage risk reference value C _Lj for specifying the evacuation position are stored in one table, but they may be stored in separate tables.

Further, the damage risk table 377 for each evacuation position candidate stores C _oj (t) calculated for each evacuation position candidate of the elevator 1 for each evacuation position candidate. Although each floor (1F to 10F) is used as the evacuation position candidate (j) in this table as well, it is not limited to floors and may be used in the middle of the floor.

Next, the configuration of the center device 4 will be described. The center device 4 includes a communication processing section 41 , a weather information extraction processing section 42 and a storage section 43 . First, the communication processing unit 41 receives weather information data over a wide area such as the whole country from a weather information data service company (not shown) or the like via the communication line (A) 6 . Further, the communication processing unit 41 is connected to the information terminal 5 owned by the manager of the elevator 1, the information terminal 5 owned by the worker who performs the maintenance work, and the monitoring device 3 via the communication line (A) 6. . Then, change information of the operating state is received from the monitoring device 3 to the manager or the person in charge of maintenance of the elevator 1 .

The weather information extraction processing unit 42 extracts local weather information data stored in the storage unit 43 from wide-area weather information data received from a weather information data service company or the like, and stores the data in the storage unit 43 . Note that these weather information data include at least wind speed, wind direction, amount of precipitation, and atmospheric pressure.

The storage unit 43 stores installation position information of the elevator 1, information on the manager and maintenance personnel of the elevator 1, wide-area weather information data, and nearby weather information data received from the weather information data service company.

Next, the information terminal 5 will be described. The information terminal 5 includes an elevator manager information terminal 51 possessed or used by the manager of the elevator 1, and a maintenance worker information terminal 52 possessed or used by a maintenance worker. Each information terminal 5 is connected to the center device 4 via a communication line (B) 7, performs communication, and receives information transmitted from the monitoring device 3 via the center device 4 to the manager and maintenance personnel of the elevator 1. receive the change information of the operating state.

Note that each of the monitoring device 3, the center device 4, and the information terminal 5 is realized by a so-called computer. The functions and processes of each device are executed by an arithmetic device such as a CPU according to a program. In particular, in the monitoring device 3, 31 to 33 are interface units, 34 to 36 are programs and an arithmetic unit (CPU), and 37 can be realized by a storage medium.

Next, the processing procedure of the elevator control system according to this embodiment will be described using the flowchart shown in FIG.

First, the center device 4 periodically (for example, regularly) receives wide-area weather information data from a weather information data service company (not shown) via the communication line (A) 6 . Then, the data is stored in the storage section 43 of the center device 4 (step S201). The wide-area weather information data is weather information data provided by a weather information data service company, and may include weather information data for the area where the building 2 is located.

Next, in the weather information extraction processing unit 42, from the wide area weather information data, nearby weather information for the information indicating the installation position of the elevator 1 or the building 2 (hereinafter referred to as the installation position information of the elevator 1) stored in the storage unit 43 Extract data. Then, a process of storing the extracted weather information data in the storage unit 43 is performed (step S202).

Here, FIG. 3 is a schematic diagram showing a state in which the local weather information data is extracted from the wide-area weather information data collected by the center device 4. As shown in FIG.

Here, wide-area weather information data is a set of measurement points of a large number of weather information data, and at least one measurement point exists in each grid obtained by dividing a map into a mesh. Therefore, from the installation position information of the elevator 1, the measurement point of the weather information data closest to the installation position of the elevator 1, and the east, west, south, north, southeast, northeast, southwest, northwest (e, w, s, n, se, ne, sw, nw) are identified and extracted. That is, in FIG. 3, (1) wide area to (2) neighborhood are specified. Then, the weather information data in the vicinity of the elevator 1 and the building 2 and the surrounding area at the time of (2) measurement in the vicinity extracted by this operation can be extracted as the vicinity weather information data. As described above, in the present embodiment, the neighborhood uses the area of the adjacent measurement points, but it is sufficient if the area where the elevator 1 or the building 2 is installed is included in a more limited range than the wide area. . Furthermore, in this embodiment, the local weather information data is extracted from the wide area weather information data, but in step S201, the center device 4 may receive the local weather information data and use it.

Returning to FIG. 2 again, the processing procedure will be described from step S203. Next, the communication processing unit 41 of the center device 4 transmits the nearby weather information data to the monitoring device 3 of the elevator 1 . Then, the monitoring device 3 receives the local weather information data transmitted by the communication processing unit 31 (step S203). Also, in the monitoring device 3 , the local weather information data received in step S<b>203 is stored in the local weather information data table 371 of the storage unit 37 .

On the other hand, the monitoring device 3 periodically (for example, periodically) inputs the detected weather information data detected by the sensors of the anemometer 21, the wind vane 22, the rain gauge 23, and the barometer 24 of the building 2 to the input processing unit 33. to accept. Then, the monitoring device 3 stores the detected weather information data in the detected weather information data table 372 of the storage unit 37 (step S204).

Next, the judgment processing unit 34 of the monitoring device 3 uses the nearby weather information data stored in the nearby weather information data table 371 and the detected weather information data stored in the detected weather information data table 372 to determine the damage to the elevator 1 itself. A risk is calculated (step S205). A method of calculating this damage risk will be described with reference to FIGS.

FIG. 4 is a schematic diagram showing the degree of influence of future weather conditions at the location where the elevator 1 is installed, according to local weather information data set based on regional and geographical characteristics of the location where the elevator 1 is installed.

First, the local weather information data received by the monitoring device 3 and monitored by the monitoring device 3 includes wind speed W _x , wind direction D _x , amount of precipitation R _x , and atmospheric pressure P _x . Here, x is the measurement point located near the installation location of the elevator 1 as x = 0, and with this measurement point as the reference, the measurement points adjacent to the east, west, south, north, southeast, northeast, southwest, and northwest are As mentioned above, they are expressed as x=e, w, s, n, se, ne, sw, nw, respectively.

For example, if the area where Elevator 1 is installed is in an area where the weather changes from west to east over time, the current weather information data for the west side: point w will correspond to the future climate at the location where Elevator 1 is installed. considered to have the greatest impact. On the contrary, it is considered that the present meteorological data of the east side, the northeast side, and the southeast side, that is, the e point, the ne point, and the se point will have little influence on the future climate of the location where the elevator 1 is installed.

Therefore, the degree of influence of wind speed W _x , wind direction D _x , amount of rainfall R _x , and air pressure P _x at point x in the vicinity of elevator 1 installation position o at present (t) is A _Wx, , A _Dx , A _Rx , A, respectively. Expressed as _Px , the predicted value of the weather data at the installation position of the elevator 1 at (t+1) from now on can be calculated by the following Equations 1 to 4. A _Wx, , A _Dx , A _Rx , and A _Px are stored in the neighborhood influence table 373 as described above.
W' ₀ (t+1) = ΣA _Wx W _x (t) ... (Equation 1)
D' ₀ (t+1) = ΣA _Dx D _x (t) ... (Equation 2)
R' ₀ (t+1) = ΣA _Rx R _x (t) ... (Equation 3)
P' ₀ (t+1) = ΣA _Px P _x (t) ... (Formula 4)
FIG. 5 shows (a) the floor plan of the building 2 and (b) the wind direction installed in the building 2 and the weighting (correlation degree) of the damage risk of the elevator 1, which is set from the structural characteristics and architectural environment characteristics of the building 2 ) is a schematic diagram showing. Note that (b) shows the degree of correlation by taking the wind direction as an example among the wind speed, wind direction, amount of precipitation, and air pressure (weather information data).

First, the detected weather information data obtained from the anemometer 21, anemoscope 22, rain gauge 23, and barometer 24 provided in the building 2 are W, D, R, and P, respectively.

Depending on the building 2, rainwater may flood into the elevator 1 due to the structural characteristics of the building 2 and the characteristics of the building environment, even if the amount of rainfall and wind speed are the same, in the case of a certain wind direction. Fig. 5(a) shows a plan view of the building 2. The north side of the building 2 is a corridor, the elevator 1 is installed at the east end, and the elevator hall and the corridor are an open space. It is shown that. In this case, as shown in FIG. 5(b), if the north wind or the wind from the northeast is strong, rain will blow in. If there is a lot of rainfall and strong wind speed, there is a risk that water will flood the hoistway of the elevator 1 through the elevator hall. However, when the wind direction is south or southwest, almost no rain blows in even when there is a lot of rainfall, and the possibility of water flooding the hoistway of the elevator 1 is small.

Therefore, if the current (t) wind speed W, wind direction D, precipitation (rainfall) R, and air pressure P on the damage risk of elevator 1 are respectively B _W , B _D , B _R , and B _P , the current time is The damage risk C _o (t) of the elevator 1 at (t) can be calculated by Equation 5 below. These B _W , _BD , _BR , and _BP are stored in the detection impact level table 374 as described above.
C _o (t) = f(W(t), D(t), R(t), P(t), B _W , B _D , B _R, B _P ) (Formula 5)
As an example of Equation 5, Equation 6 may be used.

C _o (t)＝W(t)*B _W +D(t)*B _D +R(t)*B _R +P(t)*B _P ”…(Formula 6)
Furthermore, the damage risk C _o '(t+1) of the elevator 1 based on the predicted value of the weather data at the installation position of the elevator 1 from now (t+1) can be expressed by Equation (7).
C _o '(t+1) = f(W' ₀ (t+1), D' ₀ (t+1), R' ₀ (t+1), P' ₀ (t+1), B _W , B _D , B _R , B _P ) (Equation 7)
Therefore, the damage risk C t) can be calculated by Equation 8 using the coefficient α.
C(t)=α・C _o (t) + (1−α)・C _o '(t+1)
＝α・f(W(t), D(t), R(t), P(t), B _W , B _D , B _R , B _P )
+(1-α)・f(W' ₀ (t+1), D' ₀ (t+1), R' ₀ (t+1), P' ₀ (t+1), B _W , B _D , B _R , B _P )
(However, 0≤α≤1) …(Formula 8)
In this embodiment, the damage risk is calculated by the determination processing unit 34 of the elevator 1 by the above method. Note that this calculation is an example, and that method may be used.

With this, the description of step S205 is completed, and returning to FIG. 2, the processing procedure will be described from step S206. Next, the damage risk C(t) is compared with the damage risk reference value C _L stored in the damage risk reference value table 376 of the storage unit 37 (step S206). As a result of the comparison, when the damage risk C(t) is higher, the process proceeds to step S207, and when it is lower, the process returns to step S201.

Next, the determination processing unit 34 _{calculates the damage risk C oj (} t) for each evacuation position candidate of the car, that is, the damage risk C _ojj (t) for each evacuation position candidate, and causes the car of the elevator 1 to evacuate and stop. The floor is determined by the determination processing unit 34 (step S207).

Further, the determination processing unit 34 determines the retraction position (step S208). Thus, in this embodiment, the damage risk of the elevator 1 itself (entirely) is calculated in step S205, and then the damage risk for each evacuation position candidate is calculated in step S207. As a result, when the risk of damage to the elevator 1 as a whole is low and evacuation is unnecessary, it is possible to save the trouble of calculating the damage risk for each of the plurality of evacuation position candidates. However, the calculation in step S205 may be omitted, and the calculation of the damage risk for each evacuation position candidate in step S207 may be performed after step S204.

Further, in the present embodiment, the damage risk and the damage risk for each evacuation position candidate are calculated during control, but these may be specified using a condition table prepared in advance. In this case, it is desirable to provide this condition table in the storage unit 37 of the monitoring device 3 . In addition, the content is recorded in association with the nearby weather information data and the detected weather information data, the damage risk, and the damage risk for each evacuation position candidate. Also, as the condition table, the nearby weather information data, the detected weather information data, and the one specifying the evacuation position may be used. That is, the nearby weather information data table 371, the detected weather information data table 372, and steps S207 and S208 will be described below with reference to FIG. FIG. 6 schematically shows a damage risk calculation method for each evacuation candidate position.

As explained in FIG. 5, if the current (t) wind speed W, wind direction D, rainfall amount R, and air pressure P affect the damage risk of the elevator 1 as B _W , _BD , _BR , and _BP respectively, The damage risk C _o (t) of the elevator 1 at the current time (t) can be calculated using Equation 5 above.
C _o (t) = f(W(t), D(t), R(t), P(t), B _W , B _D , B _R, B _P ) (Formula 5)
Here, strictly speaking, each floor (each position) has a different damage risk. For example, as shown in Figure 5, when the wind blows in a certain direction, the risk of flooding from the hall on the top floor is the highest, but when the wind speed is not high and the amount of rainfall is large, flooding in the pit is at the highest risk. Therefore, in order to evacuate the car to a safe position, it is necessary to select the position with the lowest risk of damage from a plurality of candidates for the evacuation position.

Therefore, the degree of impact on the damage risk of the elevator 1 at the current (t) wind speed W, wind direction D, precipitation amount R, and pressure P candidate j (j = 1 to m) on the damage risk of the elevator 1 is B _Wj , B _Dj , B Assuming that _Rj and B _Pj , the damage risk C _oj (t) for each evacuation position candidate j at the current time (t) can be calculated by Equation 9 below. B _Wj , B _Dj , B _{Rj , and} B _Pj ) are stored in the evacuation position candidate influence table 375 as described above.
C _oj (t)=f(W(t), D(t), R(t), P(t), B _Wj , B _Dj , B _Rj, B _Pj ) (Formula 9)
This is calculated by the number of evacuation position candidates j (j=1 to m), and the evacuation position that has the minimum damage risk C _oj (t) for the elevator 1 with the minimum damage risk C _oj (t) for each evacuation position candidate is determined. (Step S208). The calculated damage risk by evacuation position candidate C _oj (t) is stored in the damage risk table by evacuation position candidate 377 (m=10 in the example of FIG. 9).

In steps S207 and S208 described above, the determination processing unit 34 calculates the damage risk C _oj (t) for each evacuation position candidate for each floor where the elevator 1 can be stopped. Then, the determination processing unit 34 specifies, as the evacuation position, the floor with the minimum damage risk _Comin (t) among the damage risks C _oj (t) for each evacuation position candidate for each floor on which rest is possible.

In steps S207 and S208, the calculation of the damage risk C _oj (t) for each evacuation position candidate may not be limited to floors. In other words, the calculation may be performed by using a position shifted from the floor as a candidate evacuation position as long as it is a position where the vehicle can rest. Alternatively, the evacuation position may be specified as a position where the damage risk C _oj (t) for each evacuation position candidate is equal to or less than a predetermined threshold. In this case, the damage risk reference value C _Lj or the damage risk reference value C _L for specifying the evacuation position stored in the damage risk reference value table 376 is used as the threshold value. Also, other values other than these may be used. As for other values, it is more desirable to ensure safety by using a value smaller than the damage risk reference value C _L . In addition, when the retreat position below the threshold cannot be identified, the position of the smallest damage risk C _oj (t) by retreat position candidate is identified as the retreat position.

Note that the damage risk C(t) for each evacuation candidate position may be calculated in order of proximity from the position of the elevator 1 . In this case, among the evacuation position candidates of the damage risk C _oj (t) for each evacuation position candidate that is equal to or less than the threshold, the evacuation position candidate closest to the current position is specified as the evacuation position.

With this, the description of steps S207 and S208 is completed, and the description returns to the flowchart of FIG. 2, and the processing procedure is described from step S209. The monitoring device 3 of the elevator 1 transmits the evacuation position determined by the determination processing section 34 to the operation control command section 35 . Then, the operation control command unit 35 transmits an evacuation operation command to the elevator control unit 11 via the communication processing unit 32 . This evacuation operation command includes the evacuation position identified in step S208. In accordance with this command, the elevator control unit 11 moves the car of the elevator 1 to the designated evacuation floor and suspends the operation of the elevator 1 . Then, the elevator control unit 11 causes the elevator display unit 12 to display that operation is suspended (step S209).

Next, the monitoring device 3 of the elevator 1 transmits to the center device 4 via the communication processing section 32 and the communication line (B) 7 that the operation of the elevator 1 has been suspended (step S210).

When the communication processing unit 41 of the center device 4 receives the information that the operation of the elevator 1 has been suspended, it extracts contact information from the information of the manager and maintenance personnel of the elevator 1 stored in advance in the storage unit 43. . The contact information includes information specifying the elevator manager information terminal 51 and maintenance worker information terminal 52, and the e-mail addresses of the elevator manager and maintenance workers. Then, the communication processing unit 41 transmits the information of the suspension of operation of the elevator 1 to the elevator manager information terminal 51 and the maintenance worker information terminal 52 via the communication line (B) 7 (step S211).

In the elevator control system of this example described above, the weather information data around the elevator 1 and the wind speed, wind direction, amount of precipitation, and air pressure in the building 2 where the elevator 1 is installed are used to determine if a storm such as a typhoon occurs. to a floor with a lower risk of damage. This low damage risk floor includes the lowest floor or location and the floor or location below the threshold. Therefore, damage to the elevator 1 can be prevented.

Furthermore, the monitoring device 3 can predict that the risk of damage to the elevator 1 is increasing based on the weather information data near the installation position of the elevator 1 obtained from the center device 4 . Further, based on weather information data obtained from an anemometer 21, a wind vane 22, a rain gauge 23, and a barometer 24 provided in the building 2 where the elevator 1 is installed, the elevator 1 is controlled to move to an appropriate evacuation position. It is possible to reduce the risk of damage.
