Elevator control device Technical field

TECHNICAL FIELD The present invention relates to an elevator control device that performs a control operation in response to weather changes such as lightning strikes, strong winds, and rain and snow in an elevator for outdoor observation.

Background art

Normal elevators have a car inside the building, so they are not directly affected by weather changes. However, for example, if a building is struck by lightning, the lightning current then flows into the hoistway, which breaks down the electrical system of the elevator control system and shuts out passengers in the car. There is a thing. In addition, when the building shakes due to strong winds, the car swings with it, which may cause anxiety to the passengers in the car.

Conventionally, in order to solve such problems, for example, by detecting the approach of lightning with a lightning detection sensor, the emergency stop of the car to the nearest floor when approaching lightning, and the closing of passengers The accident was prevented. In addition, by detecting a strong wind by a strong wind detection sensor, the influence of the strong wind is avoided by performing control operations such as deceleration operation, intermediate floor waiting or suspension according to the strong wind level at that time. Was.

In recent years, with the diversification of customer needs, elevators for outdoor observation have been developed. The outdoor observation elevator is an elevator in which the car is installed outside, and passengers can enjoy the outdoor scenery while the car is moving up and down. But this way The problem with outdoor elevators for outdoor observation is that the car itself is located outdoors, so it is directly affected by weather changes.

That is, for example, if there is a lightning strike, there is a possibility of going straight to the car. This not only poses a danger to passengers, but can also damage equipment due to direct lightning strikes. In addition, when the wind is strong, the car may shake greatly, causing ropes to get entangled or the car to be damaged by hitting the car. Therefore, continuing normal operation when there is a large amount of descent involves danger.

In this way, the elevator for outdoor observation has a direct effect on the car itself, unlike ordinary elevators, so it is necessary to control the traffic taking this point into account. However, hitherto, no consideration has been given to the possibility of lightning strikes directly on a car exposed outdoors or the danger of being directly affected by strong winds.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First Embodiment)

FIG. 1 is a diagram showing the configuration of an elevator for outdoor observation to which the elevator control device of the present invention is applied. 1 in the figure is a car,

2 is a hoisting machine, 3 is a main rope, 4 is a counterweight, 5 is a car control device, 6 is a display device in the car, and 7 is an analysis device in the car.

The elevator for outdoor observation has a car 1 installed outside the building. Car 1 moves up and down between the landing floors from the top floor to the bottom floor of the building. In addition, a specific floor of each landing floor is prepared as an evacuation floor 8. This evacuation floor 8 is provided on the top floor, for example, as shown in Figure 2. The evacuation floor 8 is covered from the outside and exists as a service floor that can avoid direct hits such as lightning.

Here, the elevator control device 11 is installed together with the hoisting machine 2 in the machine room 10 further up on the top floor of the building. (Main microcomputer device) 110, I / O device 111, and priority order table 112 are provided. The CPU 110 controls the entire elevator and, by reading a program, executes a predetermined process in accordance with the procedure described in the program. For example, when a landing power s from a landing force is applied, the CPU 110 drives the hoisting machine 2 via the inverter (motor driving device) 12 and puts the car 1 on its own. Move to the floor where the call was made.

The input / output device 1 1 1 performs input / output processing of various signals. Each device including the display device 14 of the monitoring room 13 is connected to the input / output device 111. In addition, a weather information detecting device 15, an earthquake sensor 16, and a fire sensor 17 are connected to the input / output device 111.

The priority order table 1 1 2 is a table in which the priorities of various control operations are specified. The priority order table 112 will be described later in detail with reference to FIG.

The weather information detection device 15 is a device for detecting a weather condition. The weather information detection device 15 includes a lightning detection device 15a, a strong wind detection device 15b, and a rainfall snow detection device 15c.

The lightning detection device 15a includes, for example, a lightning sensor. When the approach of lightning is detected, the lightning detection device 15a sends a lightning warning level signal S1 or a lightning warning level signal S2 according to the approaching distance of the lightning at that time. Output to The strong wind detection device 15b includes, for example, an anemometer. When the strong wind detection device 15b detects the wind speed near the elevation of the car 1, the strong wind detection device 15b generates the first strong wind level signal S3 or the second strong wind level signal S4 according to the wind speed level at that time. Output to elevator control device 1 1 You. The rainfall snow detector 15c is, for example, a rain gauge. For snow, the snow is returned to the water by a heater, for example, and converted into rainfall. The rain / snow detector 15c outputs a rain / snow operation level signal S5 to the elevator controller 11 when it detects a snowfall of the first level or more. In addition, this rainfall snow detection device 15c outputs the flooded level signal S6 to the elevator when the rainfall snowfall of the first level or more, such as the pit 9 shown in Fig. 2 is flooded, is detected. Output to controller 1 1.

Further, the earthquake detector 16 detects an earthquake that has occurred around the building and outputs an earthquake detection signal to the elevator controller 11. The fire detector 17 detects a fire in the building and outputs a fire detection signal to the elevator controller 11.

In such a configuration, in the first embodiment, by detecting the approach of the lightning using the lightning detection device 15a provided in the weather information detection device 15, the distant lightning and the near lightning are detected. It is characterized by performing two-stage control operation with lightning. A distant lightning is a lightning cloud that occurs between 15 km and 30 km and approaches the vicinity within 30 to 60 minutes. Proximity lightning is a lightning cloud in which a thundercloud is generated at a close distance and may fall within 10 to 20 minutes.

FIG. 3 is a flowchart showing a detonation control operation process of the elevator control device 11 according to the first embodiment of the present invention.

During the operation of the elevator, if the approach of a thundercloud is detected by the lightning detection device 15a provided in the weather information detection device 15, the weather information detection device 15 is transmitted via the input / output device 111. Elebei It outputs a signal indicating that lightning is approaching the data controller 11 (step All). Specifically, the approach range of the thundercloud and the magnetic field strength in the sky are set in advance in the lightning detector 15a. The weather information detection device 15 compares the set value with the lightning detection value to determine whether the current lightning state is a distant lightning or a close lightning. It outputs a lightning warning level signal S 1 for distant lightning, and a lightning warning level signal S 2 for near lightning.

Here, when the lightning warning level signal S 1 is input (No in step A 12), the elevator control device 11 displays the display device 14 installed in the monitoring room 13. Display a lightning warning and an alarm buzzer or voice message as needed

(Step A13). This notifies the operation manager that lightning is approaching. Control operation performed at such a lightning warning level is referred to as “fire control operation 1”.

On the other hand, if the signal input from the lightning detection device 15a to the elevator control device 11 is the lightning alarm level signal S2 (Yes in step A12), a lightning strike near the building concerned there is a possibility. In such a case, the elevator control device 11 notifies the passengers in the car 1 of the suspension of the operation due to the approach of lightning by using the display device 6 and the announcement device 7 or the like. Together, urge passengers to get off

(Step A14). Subsequently, the elevator control device 11 checks the traveling state of the car 1 (step A15). If the car 1 is stopped (No in step A15), the elevator control device 11 stops at the landing floor, that is, the evacuation floor 8, where the possibility of direct lightning strike is the lowest. To determine whether they are A16). When the car 1 is stopped on the evacuation floor 8 (No in step A16), the elevator control device 11 stops the operation at the evacuation floor 8 and waits (step A). 1 8).

If car 1 is stopped on a floor other than the evacuation floor 8 (Yes in step A16), elevator controller 11 cancels the destination call at that time. After moving car 1 to the safe evacuation floor 8 and waiting there (step A 19), there is a possibility that passengers may still be in car 1. For this reason, the display device 6 and the announcement device 7 are used to notify the user of service interruption and to encourage passengers to get off.

If the car 1 is traveling (Yes in step A15), the elevator control device 11 determines whether the car 1 is traveling in the direction of the evacuation floor 8 or not. Is determined (step A17). If the car 1 is traveling in the direction of the evacuation floor 8 (Yes in step A17), the elevator controller 11 cancels the call to the floor on the way to the evacuation floor 8. And move car 1 to evacuation floor 8. At this time, since there is a possibility that passengers may be in car 1, use a display device 6 or an announcement device 7 to indicate that the passengers in car 1 will stop operating to approach lightning. To notify passengers to get off. After a certain period of time, the door of car 1 is closed to stop the operation (step A21). If the car 1 is running in the opposite direction to the evacuation floor 8 (No in step A17), the elevator control unit 11 arrives at the first destination floor. Doors open after the floor, indicating that passengers in car 1 will stop operating due to approaching lightning. And notify the passengers using a traffic device 7 to urge the passengers to get off. After that, the call is canceled, and car 1 is returned to the evacuation floor 8 for operation. After landing on the evacuation floor 8, close the door for a certain period of time after opening the door, and suspend operation (Step A20).

There is a possibility that passengers may be in car 1 even while driving back to evacuation floor 8. Then, the passengers of car 1 are notified again of the suspension of the operation due to the approach of lightning using the display device 6 and the announcement device 7 to urge the passengers to get off. After opening the landing door on evacuation floor 8, close the car door a certain time later and suspend operation. Control operation performed at such a lightning warning level is called “priming control operation 2”.

This “Rapid Control Operation 2” monitors the condition of lightning while car 1 is waiting at the evacuation floor 8. For example, if the lightning warning level signal S2 or the lightning warning level signal S1 is released (for example, Yes in step A23) after the thundercloud leaves, if it is not detected again within a certain time ( In step A23, No), the operation returns to normal operation (step A24).

In this way, when the approach of lightning is detected in the outdoor observation elevator, if there is no possibility of a lightning strike nearby and there is only a thundercloud approaching (during distant lightning), the elevator will be operated. Notify the administrator and warn them. On the other hand, if there is a possibility of lightning nearby (when there is a nearby lightning), the car 1 exposed outdoors is moved directly to the evacuation floor 8, which is the service floor that is least affected by lightning. As a result, it is possible to secure the safety of passengers when lightning approaches, and to prevent damage to equipment due to lightning. (Second embodiment)

Next, a second embodiment of the present invention will be described.

In the second embodiment, in the configuration of FIG. 1 described above, the wind speed is detected by using the wind speed detection device 15 b provided in the weather information detection device 15, whereby the value of the wind speed at that time is obtained. It is characterized in that a two-stage control operation is performed according to the conditions. Figure 4 shows the processing operation.

FIG. 4 is a flowchart showing a strong wind control operation process of the elevator control device 11 according to the second embodiment of the present invention.

During elevator operation, the wind speed near the elevation of the car 1 is detected by the wind speed detection device 15b provided in the weather information detection device 15 (step B11). This wind speed detector 1

5 If the wind speed detected by b is less than A (m / s) (No in step B12), the elevator control device 11 will reach the rated speed a (m / min). To perform normal operation (Step B 1

3). The rated speed a is, for example, 360 mZ min.

Here, when the wind speed detector 15b detects the wind speed A (m / s) or more (Yes in step B12), the weather information detector 15 is connected to the input / output device 1 A strong wind detection signal is output to elevator control unit 11 via 11. In this case, wind speed detector

In 15b, several strong wind detection levels can be set. In this embodiment, two levels of strong wind detection levels are set. When the wind speed is equal to or higher than the wind speed A (m / s) and lower than the wind speed B (m / s) (No in step B14), the meteorological information detection device 15 outputs the first strong wind level signal S3. Output to elevator controller 1 1. wind speed In the case of B (m / s) (Yes in step Bl4), the meteorological information detection device 15 outputs the second strong wind level signal S4 to the elevator control device 11 I do. Specifically, wind speed A is 15 m / s and wind speed B is 20 m / s.

When the first strong wind level signal S 3 is input to the elevator control device 11, the elevator control device 11 changes from the rated speed a (m / min) to the preset speed b (m / min). Decelerate and continue operation (Step B15). The speed b is, for example, 1/2 of the specified speed a, and specifically, 180 mZmin. In this case, when the first strong wind level signal S 3 is detected, if the car 1 is stopped, the car is switched to the above-mentioned speed b from the point of operation in response to the next call, and the operation is started. . When the first strong wind level signal S 3 is detected and the car 1 is running, the rated speed a before the input of the first strong wind level signal S 3 is reached until the current destination floor. Keep the vehicle running. Then, after reaching the target floor, the system switches to speed b and starts operation when answering the next call. Such a control operation performed at the first strong wind level is referred to as “strong wind control operation 1”.

Also, when the wind speed detecting device 15b detects a wind speed B or more and the second strong wind level signal S4 is input to the elevator control device 11, the elevator control device 11 Is moved to the evacuation floor 8, which is the service floor with the least impact of strong winds (Step B16). In this case, when the second strong wind level signal S4 is input and the car 1 is on the service floor where the car 1 is on the floor, the service is stopped by the display device 6 or the announcement device 7. Squared After informing the customer and opening the door for a certain period of time, take the evacuation floor 8 and move the car 1.

Also, there is a possibility that passengers are riding in car 1 while moving to evacuation floor 8. Therefore, the landing door is opened on the evacuation floor and the service stop is notified again by the display device 6 and the announcement device 7. After prompting the passengers to get off, the door is closed after a certain period of time to stop driving. (Step B17). Such a control operation performed at the second strong wind level is referred to as “strong wind control operation 2”.

Even when the operation is suspended due to “strong wind control operation 2”, the elevator control device 11 monitors the signal from the wind speed detection device 15 b (step B 18). If the wind speed falls below B within a certain period of time (for example, 10 minutes), and the second strong wind level signal S4 is released (No in Step B19). ), The elevator controller 11 resumes the operation of the car 1 at the speed b from the evacuation floor 8 (step B20). In this case, if the wind speed continues to be equal to or higher than A and lower than B (No in step B21 → B22), the operation at speed b is continued.

On the other hand, when the wind speed becomes B or more (Yes in step B22), the processing returns to the processing from step B16 above, and the "strong wind control operation" is performed again.

2 ”, operation to evacuation floor 8 is performed. If the wind speed A or more is not detected within the fixed time in the above step B21, the operation returns to the normal operation at the rated speed a (step B2).

3).

In this way, when the strong wind level exceeding a certain set value is detected in the outdoor observation elevator, the speed becomes lower than normal. By decelerating and continuing driving, it is possible to suppress the swing of the car 1 during traveling and to prevent the passengers from feeling uneasy. In addition, it is possible that the car 1, rope 3, and the counterweight 4 that are exposed outdoors may be damaged by strong winds and entangled with other equipment. Therefore, when a wind speed at a level higher than the above-mentioned strong wind level is detected, the car 1 is moved to the evacuation floor 8 which is a service floor where the influence of the strong wind is less. As a result, passenger safety can be ensured, and equipment damage due to strong winds can be prevented.

(Third embodiment)

Next, a third embodiment of the present invention will be described.

In the third embodiment, in the configuration of FIG. 1 described above, the amount of rainfall and snow is detected by using the rainfall snowfall detection device 15 c provided in the weather information detection device 15, and at that time, It is characterized by performing traffic control operation according to the amount of rainfall and snowfall. Figure 5 shows the processing operation.

FIG. 5 is a flowchart showing a rainfall and snowfall control operation process of the elevator control device 11 according to the third embodiment of the present invention. The weather information detection device 15 is provided during the elevator operation. The amount of rainfall snow is detected by the rainfall snow detector 15c (step C11). The rain / snow detector 15c is, for example, a rain / snow gauge for measuring the amount of rainfall. Snow is converted back to water by a heater and converted as rainfall. When a rainfall snowfall of a predetermined first level or more (for example, 1 Omm / h) is detected (Ye in step C11) s) The rain / snow operation level signal S5 is output from the rain / snow detector 15c. By inputting the rain / snow operation level signal S5 via the input / output device 111, the elevator control device 11 establishes the evacuation floor 8, which is the service floor with the least influence of rain / snow. Switch to return operation (home landing operation) as the standard floor (Step C12). Performing the return operation according to the amount of rainfall and snow is called "rainfall snow control operation".

In this “rain and snow control operation”, the car 1 is parked at the evacuation floor 8, and when there is a call from the car or the landing, the car 1 operates as usual and responds to the call. After operation, wait at the retreat evacuation floor 8. If there is no call from the car or platform, keep waiting at the evacuation floor 8 to prevent car 1 from getting wet.

In addition, even during the “rainfall and snow control operation”, the rainfall is continuously monitored by the rainfall and snow detection device 15c. If a rainfall of the first level or more is detected again within a certain time (for example, 10 minutes) (No in step C13), the elevator controller 11 Will extend “rainfall and snow control operation”. On the other hand, if the rainfall at or above the first level is not detected after the lapse of the predetermined time (Yes in step C13), the operation returns to the normal operation (step C14).

When a large amount of rain or snow falls and the rainfall reaches a second level or more that causes the pit 9 to be flooded (Yes in step C15), the flooding level is detected by the rainfall and snow detector 15c. The signal S 6 is output to the elevator controller 11. As a result, The elevator control device 11 lowers the passenger on the nearest floor, evacuates the car 1 to the evacuation floor 8, and then puts the vehicle in an operation stop state (step C16).

As described above, when a certain amount of rainfall or snowfall is detected in the outdoor observation elevator, operation is performed with the evacuation floor 8 as the reference floor, and a call from the car or platform must not occur. For example, waiting at the evacuation floor 8 can prevent the car 1 from being exposed to rain. Also, when the pit section 9 reaches a rainfall level at which there is a possibility of flooding, the passengers are lowered and the car 1 is evacuated to the evacuation floor 8 to ensure the safety of the passengers and This prevents damage to the equipment due to flooding.

(Fourth embodiment)

Next, a fourth embodiment of the present invention will be described.

In the first to third embodiments, each one of the lightning detection device 15a, the wind speed detection device 15b, and the rainfall snow detection device 15c provided in the weather information detection device 15 is used. Although the control operation in this case has been described, it is also possible to perform the control operation suitable for the current weather environment by using these detectors 15a to 15c. In addition, it is possible to control the operation by adding an earthquake detector 16 and a fire detector 17 installed separately from the weather observation.

In the following, in the configuration of Fig. 1 above, the lightning detection device 15a, wind speed detection device 15b, rainfall snow detection device 15c, earthquake sensor 20 and lightning detection device 15a provided in the weather information detection device 15 Control operation based on various weather information and earthquake and fire information using fire detector 17 The case of performing is described.

As described above, the control operations using the lightning detection device 15a include “lightning control operation 1” (a lightning warning is issued to the operation manager to continue operation) and “lightning control operation 2”. (The car 1 is evacuated to the evacuation floor 8 and operation is suspended.) In addition, as the control operation using the wind speed detector 15b, “strong wind control operation 1” (operating at a reduced speed) and “strong wind control operation 2” (car 1 retreats to evacuation floor 8). To avoid operation suspension). In addition, as a control operation using the rain / snow detector 15c, there is “rain / snow control operation” (home-landing operation using the evacuation floor 8 as a reference floor).

Apart from these weather control operations, there are “earthquake control operation” using earthquake detectors 20 and “fire control operation” using fire detectors 17. The priority order table 111 stores the priorities of these control operations. Figure 6 shows an example.

FIG. 6 is a diagram showing a configuration of the priority order table 1 12 of the elevator control device 11 in the fourth embodiment of the present invention. The priority is determined in the order of "earthquake control operation", "fire control operation", "fire control operation 2", "strong wind control operation 2", and "rainfall snow control operation". “Raise control operation 1” and “strong wind control operation 1” are control operations for which no priority is assigned. Regarding these two control operations, information indicating whether or not the control operations having the above-mentioned priorities can be simultaneously executed is added. In the figure, “〇” indicates that simultaneous execution is possible, and “X” indicates that simultaneous execution is not possible. In the priority order table 1 12 of such a configuration, when an earthquake occurs, “earthquake control operation” has the highest priority. In “Earthquake control operation”, the use of elevators is prohibited when an earthquake occurs (call cancellation). In addition, according to the seismic intensity level detected by the seismic sensor 20, emergency stop at the spot and stop to the nearest floor are performed to secure the safety of passengers in the car 1. Subsequently, “fire control operation” is executed. In the “fire control operation”, when a fire is detected by the fire detector 17, the driver pulls back to the floor that is most suitable for evacuation of the passengers in the car 1.

`` Raise control operation 2 '' and `` strong wind control operation 2 '' are operations in which the car 1 is moved to the evacuation floor 8 with the least effect and the service is suspended, so giving priority to rescue or getting off the passengers This is a priority following “earthquake control operation” and “fire control operation”. “Driving during rainfall and snowfall” is the operation with the lowest priority because the car 1 performs normal service with the evacuation floor 8 where the car 1 is not exposed to rain as a reference floor.

In addition, “Raise control operation 1” and “Strong wind control operation 1” are performed simultaneously with other control operations to continue the operation itself.

In this way, control operations related to meteorology and control operations for earthquakes and fires are combined and executed according to priority. As a result, safe operation can be realized in the outdoor observation elevator where the car 1 is exposed outdoors.

In the first to third embodiments, information on weather such as lightning, wind, and rain and snow is individually detected by a dedicated detection device 15a. ~ 15c. As another embodiment, for example, by using the Internet, information about weather such as lightning, wind, rain, and snow may be acquired from a specific server that provides a weather service. This can be realized by installing a terminal device for accessing the above specific server via the Internet and connecting the terminal device to the elevator control device 11. .
