Description

[Technical Field]

[0001] The present invention relates to a system for setting a waiting floor where an elevator car is to wait. [Background technology]

[0002] Elevators have designated waiting floors (park floors). A waiting floor is a floor where a car waits when not being called. The waiting floor is set from the viewpoint of elevator operating efficiency or safety in the event of a disaster. For example, in Patent Document 1, a waiting floor is set at a floor where long objects (wire ropes, etc.) that are displaced as the car moves during an earthquake are less likely to resonate with the shaking of the building.

[0011] According to the elevator waiting floor setting system of the present invention, it is possible to improve both the operating efficiency of the elevator and safety in the event of a disaster. [Brief explanation of the drawings]

[0012] [Figure 1] 1 is a schematic diagram illustrating a waiting floor setting system according to an embodiment; [Figure 2] FIG. 2 is a block diagram showing a control configuration of the control panel shown in FIG. [Figure 3] FIG. 2 is a block diagram showing a control configuration of the monitoring device shown in FIG. DETAILED DESCRIPTION OF THE INVENTION

[0013] An example of an embodiment of the present invention will be described in detail below. In the following description, specific shapes, materials, directions, numerical values, etc. are examples for facilitating understanding of the present invention, and can be appropriately changed according to the application, purpose, specifications, etc.

[0014] [Waiting floor setting system] The waiting floor setting system 10 will be described with reference to FIG.

[0015] The waiting floor setting system 10 is a system that sets a waiting floor at which the car 21 of the elevator 20 is to wait. As will be described in detail later, the waiting floor setting system 10 can improve both the operating efficiency of the elevator 20 and safety in the event of a disaster.

[0016] Here, the waiting floor is a floor where the car 21 waits when there is no call for the car 21. The waiting floor is set from the viewpoint of the operation efficiency of the elevator 20 and safety in the event of a disaster.

[0017] The waiting floor setting system 10 includes an elevator 20 having a car 21 that moves up and down in a hoistway 22 and a control panel 30 that causes the car 21 to wait at a waiting floor when there is no call for the car 21, and a monitoring device 40 that sets a waiting floor. In the waiting floor setting system 10, the control panel 30 and the monitoring device 40 are connected by a network 60.

[0018] [Elevator] Elevator 20 is installed in building 5. Building 5 in this embodiment is, for example, a complex building, with commercial facilities such as shops and restaurants located on the lower floors and offices such as offices and sales offices located on the upper floors. An observation deck is also provided on the top floor of building 5. However, building 5 of the present invention is not limited to complex buildings, and may be an office building, commercial building, etc.

[0019] The elevator 20 includes an elevator 20A that stops the car 21 at the entrance floor and lower floors of the building 5, an elevator 20B that stops the car 21 at the entrance floor and upper floors of the building 5, and an elevator 20C that stops the car 21 at the entrance floor and the top floor of the building 5. The entrance floor is the floor where the entrance and exit of the building 5 is located.

[0020] In the following, when a description is given that is common to the elevators 20A, 20B, and 20C, the elevators will be simply referred to as the elevator 20. Furthermore, common reference numerals will be used to denote devices that are common to the elevators 20A, 20B, and 20C.

[0021] The elevator 20 is a device that raises and lowers a car 21 in a hoistway 22 between landings on each floor. The car 21 picks up passengers and rises and falls according to the passengers' requests, stopping at the landings on each floor. The car 21 is hung from one end of a wire rope 23. A counterweight 24, whose weight is set so as to balance with the car 21, is hung from the other end of the wire rope 23. The car 21 and counterweight 24 are raised and lowered by an elevator 25 that uses an electric motor to rotate a pulley on which the wire rope 23 is hung.

[0022] [Control panel] The control panel 30 will be described with reference to FIG.

[0023] The control panel 30 controls each device of the elevator 20, such as the elevator 25. As described above, the control panel 30 causes the car 21 to wait at a waiting floor when there is no call for the car 21. The control panel 30 may be disposed in a machine room provided above the hoistway 22.

[0024] The control panel 30 is a computer including a CPU 31, a memory 32, and a wireless communication interface 33. The CPU 31, the memory 32, and the wireless communication interface 33 are connected by an internal bus 34. The wireless communication interface 33 is a wireless communication module that is connected to the network 60 and communicates with the monitoring device 40.

[0025] The CPU 31 is a processor that processes information. The memory 32 stores a control program 35 and control program data 36 for executing the control program 35. The CPU 31 executes the control program 35 stored in the memory 32 to realize various control operations.

[0026] The control program 35 causes the car 21 to wait at the waiting floor when there is no call for the car 21. The control program 35 is executed by the CPU 31. The control program data 36 temporarily stores data when the CPU 31 executes the control program 35, and also stores setting values ​​and the like required for executing the control program 35.

[0027] [Monitoring device] The monitoring device 40 will be described with reference to FIG.

[0028] The monitoring device 40 remotely monitors the plurality of elevators 20. As described above, the monitoring device 40 also sets waiting floors. The monitoring device 40 is installed in, for example, a management company that manages the elevators 20.

[0029] The monitoring device 40 is a computer including a CPU 41, which is a processor that processes information, a memory 42 that stores data, and a wireless communication interface 43. The CPU 41, the memory 42, and the wireless communication interface 43 are connected by an internal bus 44. The wireless communication interface 43 is a wireless communication module that is connected to a network 60 and that communicates with the control panel 30 of the elevator 20.

[0030] The memory 42 stores a processing program 45 and processing program data 46. The memory 42 may also store other programs and databases.

[0031] The processing program 45 sets, during a predetermined time period, a "damage avoidance floor" where elevator damage is less likely to occur in the event of an earthquake as a waiting floor. The processing program 45 is executed by the CPU 41. The processing program data 46 temporarily stores data when the CPU 41 executes the processing program 45, and also stores setting values ​​and the like required for executing the processing program 45.

[0032] More specifically, the processing program 45 sets the above-mentioned "damage avoidance floor" as the waiting floor during the predetermined time period, and sets the entrance floor as the waiting floor outside the predetermined time period.

[0033] As described above, the "floor where property damage can be avoided" is a floor where damage to elevator 20 can be minimized in the event of an earthquake. The "floor where property damage can be avoided" may be set based on the natural frequency of each piece of equipment in elevator 20, or may be set based on the swaying of car 21 during past earthquakes. The "floor where property damage can be avoided" may be different depending on building 5 in which elevator 20 is installed, or may be different depending on elevator 20.

[0034] In this embodiment, the predetermined time period is from 17:00 to 8:00 the following day. The predetermined time period can preferably be set by the customer. Here, the customer is the owner or manager of the building 5 in which the elevator 20 is installed.

[0035] In other words, during designated times when occupancy rates are low (from 17:00 to 8:00 the next day), the waiting floors are used as "damage avoidance floors" to improve safety in the event of an earthquake, and during times other than designated times when occupancy rates are high (from 8:00 to 17:00), the waiting floors are used as entrance floors to improve occupancy rates.

[0036] In this embodiment, the predetermined time period may be different for each of elevators 20A, 20B, and 20C. For example, for elevator 20A, the predetermined time period may be from 7:00 PM to 10:00 AM the following day, coinciding with the closing time of the commercial facility. For elevator 20B, the predetermined time period may be from 6:00 PM to 8:00 AM the following day, coinciding with the opening hours of the office. For elevator 20C, the predetermined time period may be from 4:00 PM to 10:00 AM the following day, coinciding with the non-opening hours of the observation deck. This makes it possible to achieve both improved operational efficiency and improved safety in the event of an earthquake, depending on the bank or elevator number of elevator 20.

[0037] [Another embodiment] The processing program 45 may set the predetermined time period based on the operation rate of the elevator 20. More specifically, the processing program 45 may calculate the operation rate of the elevator 20 for each hour, and set a time period that includes many hours with a low operation rate as the predetermined time period.

[0038] It should be noted that the present invention is not limited to the above-described embodiment and its modifications, and various changes and modifications are possible within the scope of the claims of this application. [Explanation of symbols]
