Embodiment 1.
FIG. 1 is a configuration diagram of an elevator system 1 according to the first embodiment.

The elevator system 1 includes an elevator 2. The elevator 2 is applied, for example, to a building having multiple floors. A hoistway 3 for the elevator 2 is provided in the building. The hoistway 3 is a long space in the vertical direction that spans multiple floors. A landing 4 adjacent to the hoistway 3 is provided on each floor of the building.

The elevator 2 includes a main rope 5, a car 6, and a control panel 7. The main rope 5 is a rope that supports the car 6 in the hoistway 3. The car 6 is a device that transports the load inside between multiple floors by traveling up and down the hoistway 3. The car 6 includes a scale 8. The scale 8 is a device that measures the load of the car 6. The car 6 travels up and down the hoistway 3 by being wound up or down through the main rope 5 by a hoist (not shown). The control panel 7 is a device that controls the operation of the elevator 2. The operation of the elevator 2 includes, for example, the travel of the car 6. The control panel 7 is arranged, for example, at the top or bottom of the hoistway 3. Alternatively, if a machine room for the elevator 2 is provided above the hoistway 3, the control panel 7 may be arranged in the machine room.

The elevator 2 is, for example, a baggage elevator 2 that transports baggage 9 in an up and down direction using a cage 6. In the elevator 2, the loading of baggage 9 into the cage 6 is performed by a transport vehicle 10 driven by a worker. The transport vehicle 10 is a vehicle that transports baggage 9, such as a forklift. In the elevator system 1, a different transport vehicle 10 may be used for each loading operation into the cage 6. In the elevator system 1, identification information that identifies the transport vehicle 10 is attached to each transport vehicle 10.

In the elevator 2, a first upper limit and a second upper limit are set in advance for the car 6. The first upper limit is the upper limit of the load weight of the car 6 when the car 6 is traveling. The second upper limit is the upper limit of the load weight of the car 6 when baggage 9 is loaded from the landing 4 onto the car 6. The second upper limit is set to be larger than the first upper limit so that a transport vehicle 10 carrying the baggage 9 can enter the car 6 when baggage 9 is loaded from the landing 4 onto the car 6. The first upper limit is, for example, the rated load capacity of the car 6. The second upper limit is, for example, a load weight that is 150% of the rated load capacity of the car 6. The elevator 2 is, for example, a C2 class loading elevator 2.

The elevator system 1 includes a monitoring device 11. The monitoring device 11 is a device that performs remote monitoring of the elevator 2. The monitoring device 11 acquires information such as the status of the elevator 2 from, for example, the control panel 7. The monitoring device 11 provides the acquired information about the elevator 2 to, for example, the manager of the elevator 2, via a network 12. The network 12 is, for example, a communications network such as the Internet or a telephone line network.

The elevator system 1 includes a support system 13. The support system 13 is a system that supports the loading of baggage 9 into the car 6 of the elevator 2. The support system 13 includes a transmission device 14, a wireless terminal 15, a display device 16, and a support device 17.

The transmitting device 14 is a device that transmits a wireless signal. The transmitting device 14 is, for example, a wireless beacon. The transmitting device 14 is arranged, for example, at the platform 4. The transmitting device 14 may also be arranged in the car 6. The transmitting device 14 may also be arranged in both the platform 4 and the car 6.

The wireless terminal 15 is a terminal device having a wireless communication function. The wireless terminal 15 is, for example, a wireless tag that transmits and receives wireless signals, or an information terminal such as a smartphone equipped with a wireless communication function. The wireless terminal 15 is attached to the transport vehicle 10, for example. The wireless terminal 15 may be carried by a worker who drives the transport vehicle 10 during loading work. In this way, the wireless terminal 15 moves together with the transport vehicle 10. The wireless terminal 15 stores the identification information of the transport vehicle 10 that moves together. The identification information of the transport vehicle 10 may be written in advance in the wireless terminal 15, or may be input into the wireless terminal 15 by a worker before loading work, etc.

The display device 16 is a device that displays the input information. The display device 16 is, for example, a liquid crystal display. The display device 16 is disposed, for example, inside the car 6. The display device 16 is disposed, for example, on the wall surface of the car 6 on the side farther from the landing 4 so that it is easily visible to the worker operating the transport vehicle 10.

The support device 17 is a device that performs information processing in the support system 13. The support device 17 is connected to the network 12. The support device 17 is, for example, a server computer. The support device 17 is, for example, placed outside the building to which the elevator 2 is applied. Alternatively, the support device 17 may be placed in the building to which the elevator 2 is applied. The support device 17 may be configured with a single piece of hardware, or may be configured with multiple pieces of hardware. The support device 17 may be a virtual machine on a cloud service. The support device 17 includes a memory unit 18, a calculation unit 19, and an output unit 20.

The memory unit 18 is a part that stores information. The weight of the transport vehicle 10 is stored in the memory unit 18. The memory unit 18 stores the weight of the transport vehicle 10 in association with the identification information of the transport vehicle 10.

The calculation unit 19 is a part that performs calculations of information. The calculation unit 19 calculates a first loading rate and a second loading rate. The first loading rate is the ratio of the load weight of the luggage 9 loaded when the cage 6 is traveling to a first upper limit. The second loading rate is the ratio of the load weight of the luggage 9 and the transport vehicle 10 when the luggage 9 is loaded into the cage 6 to a second upper limit. Here, when a worker rides in the traveling cage 6 as a cargo handler, the weight of the worker may be included in the weight of the luggage 9.

The output unit 20 is a part that outputs the information calculated by the calculation unit 19 to the display device 16. The output unit 20 outputs the information to cause the display device 16 to display the information.

Next, an example of loading luggage 9 in the elevator system 1 will be described. In this example, a worker rides in the car 6 together with the luggage 9 as a luggage handler and travels from the departure floor to the destination floor.

First, the worker registers the weight of the transport vehicle 10 to be used for the loading operation in the memory unit 18. Note that if the weight of the transport vehicle 10 is already registered in the memory unit 18, the procedure of registering the weight may be omitted. At the departure floor, the worker gets into the transport vehicle 10 that is not transporting baggage 9 and drives the transport vehicle 10. The worker drives the transport vehicle 10 and enters the inside of the car 6 that has no baggage 9 loaded on it. The worker stops the transport vehicle 10 inside the car 6. The worker gets off the transport vehicle 10 and disembarks from inside the car 6 to the landing 4.

During this time, the transmitting device 14 transmits a wireless signal. The wireless terminal 15 receives the wireless signal from the transmitting device 14. At this time, the wireless terminal 15 transmits the stored identification information of the transport vehicle 10 to the support device 17 via the network 12 by wireless signal.

The worker operates the weight registration at hall 4. The weight registration operation is performed, for example, through a hall operating panel provided at hall 4. The hall operating panel is a device that accepts operations to register hall calls. Alternatively, if the wireless terminal 15 has an operating unit such as a button or a touch panel, the weight registration operation may be performed through the wireless terminal 15.

The memory unit 18 of the support device 17 associates the load measured by the scale 8 when the weight registration operation is performed with the identification information received when the operation is performed, and stores it as the weight of the transport vehicle 10 identified by the identification information.

The worker then gets on the transport vehicle 10 and dismounts from inside the car 6 together with the transport vehicle 10. The worker drives the transport vehicle 10 to lift the baggage 9. The worker then enters the car 6 together with the transport vehicle 10 with the baggage 9 lifted.

During this time, the wireless terminal 15 receives a wireless signal from the transmitting device 14 and transmits the identification information of the transport vehicle 10 to the support device 17.

The calculation unit 19 of the support device 17 acquires the weight of the transport vehicle 10 stored in the memory unit 18 in association with the received identification information. The calculation unit 19 subtracts the acquired weight of the transport vehicle 10 from the loaded weight measured by the scale 8 to calculate the weight of the luggage 9 excluding the transport vehicle 10. The calculation unit 19 calculates a first loading rate as the ratio of the calculated weight of the luggage 9 to a first upper limit. The calculation unit 19 calculates a second loading rate as the ratio of the loaded weight measured by the scale 8, including the weight of the transport vehicle 10, to a second upper limit. The output unit 20 outputs the first loading rate and the second loading rate calculated by the calculation unit 19 to the display device 16. The display device 16 displays the input first loading rate and the second loading rate.

Figure 2 shows an example of a display on the display device 16 according to embodiment 1.

The display device 16 displays the first loading rate and the second loading rate side by side at the same time, for example, by using a horizontal band graph. In this example, the display device 16 displays a horizontal band on the lower side whose left-right length represents the first upper limit. The display device 16 aligns its left end with the horizontal band and displays a horizontal band whose left-right length represents the first loading rate. The display device 16 also displays a horizontal band on the upper side whose left-right length represents the second upper limit. The display device 16 aligns its left end with the horizontal band and displays a horizontal band whose left-right length represents the second loading rate.

The worker checks the display of the display device 16 installed inside the car 6 while in the transport vehicle 10. From the position of the right end of the horizontal strip representing the first loading rate, the worker can easily grasp how much more luggage 9 can be loaded by the transport vehicle 10. At the same time, from the position of the right end of the horizontal strip representing the second loading rate, the worker can easily grasp how much more luggage 9 can be loaded within the range in which the car 6 of the elevator 2 can travel. Based on the grasped information, the worker decides whether or not to load additional luggage 9. If additional luggage 9 is to be loaded, the worker similarly repeats loading into the car 6 by the transport vehicle 10. If additional luggage 9 is not to be loaded, the worker gets off the transport vehicle 10 at the landing 4 and gets on the car 6. The worker moves to the destination floor together with the luggage 9 as a cargo handler. After that, the worker unloads the luggage 9 from the car 6 at the destination floor.

Note that there are cases where the worker loads the luggage 9 into the cage 6 without using the transport vehicle 10. In such cases, the support device 17 may not receive the identification information. When the calculation unit 19 does not receive the identification information, it may calculate the first loading rate as the ratio of the load weight measured by the scale 8 to the first upper limit. If the load weight does not reach the first upper limit, it will not reach the second upper limit either, making it possible to make a safer judgment.

In addition, the worker who loads the baggage 9 into the car 6 using the transport vehicle 10 does not have to ride in the car 6 with the baggage 9 from the departure floor to the destination floor. The worker who loads the baggage 9 at the departure floor and the worker who unloads the baggage 9 at the destination floor may be different workers. In this case, the worker may register the weight without getting off the transport vehicle 10. At this time, the worker's weight is added to the weight of the transport vehicle 10. In this case, the operation of registering the weight may be performed, for example, through a car operation panel provided inside the car 6. The car operation panel is a device that accepts the operation of registering a car call.

In addition, some or all of the functions of the support device 17, such as the memory unit 18, the calculation unit 19, and the output unit 20, may be installed in the elevator 2 equipment, such as the control panel 7. In this case, the memory unit 18 or the calculation unit 19 may acquire information such as the measurement results of the scale 8 without going through the network 12.

In addition, when the transmitting device 14 is a wireless communication device equipped with a function for receiving wireless signals, the wireless terminal 15 may communicate with the transmitting device 14 without going through the network 12. At this time, the transmitting device 14 transmits the identification information received from the wireless terminal 15 to the support device 17. At this time, the transmitting device 14 may transmit the identification information to the support device 17 via the control panel 7 and the monitoring device 11, etc.

In addition, when the wireless terminal 15 is a smartphone or the like having a display unit, the output unit 20 may cause the display unit of the wireless terminal 15 to display information as the display device 16. At this time, the output unit 20 outputs the information calculated by the calculation unit 19 to the wireless terminal 15.

The display device 16 may also display the first loading rate and the second loading rate numerically. The display device 16 may also display the first loading rate and the second loading rate numerically and in a bar graph. The display device 16 may also display the first loading rate and the second loading rate, for example, by a circular gauge or other display method.

As described above, the elevator system 1 according to the first embodiment includes a car 6, a display device 16, and a support system 13. The car 6 has a scale 8 for measuring the load weight. A first upper limit and a second upper limit are set in the car 6. The first upper limit is the upper limit of the load weight when traveling. The second upper limit is the upper limit of the load weight when loading baggage 9 from the landing 4. The second upper limit is greater than the first upper limit. The display device 16 displays the input information. The support system 13 includes a memory unit 18, a calculation unit 19, and an output unit 20. The memory unit 18 stores the weight of the transport vehicle 10 that loads the baggage 9 into the car 6. The calculation unit 19 calculates a first loading rate as a ratio of the value obtained by subtracting the weight of the transport vehicle 10 stored in the memory unit 18 from the load weight of the car 6 measured by the scale 8 provided in the car 6 to the first upper limit. The calculation unit 19 calculates the second loading rate as a ratio of the load weight of the cage 6 measured by the scale 8 to the second upper limit. The output unit 20 outputs both the first loading rate and the second loading rate calculated by the calculation unit 19 to the display device 16 for display.

This configuration allows the worker to check both the percentage of the load weight relative to the upper limit when the car 6 is traveling, and the percentage of the load weight relative to the upper limit when loading luggage 9 from the landing 4 onto the car 6. This allows the worker to easily determine whether each of the multiple load weight conditions is satisfied.

The elevator system 1 also includes a wireless terminal 15. The wireless terminal 15 moves together with the transport vehicle 10. The wireless terminal 15 wirelessly transmits identification information of the transport vehicle 10 at the landing 4. The memory unit 18 of the support system 13 stores the weight of the transport vehicle 10 in association with the identification information of the transport vehicle 10. The calculation unit 19 obtains the weight of the transport vehicle 10 from the memory unit 18 based on the identification information of the transport vehicle 10 wirelessly transmitted by the wireless terminal 15.

With this configuration, even when multiple different transport vehicles 10 are used in the elevator system 1, each transport vehicle 10 is identified and the first loading rate and the second loading rate are calculated. This makes the information displayed on the display device 16 more accurate.

The memory unit 18 may store the weight of the transport vehicle 10 as a preset fixed value. In this case, the identification information wirelessly transmitted from the wireless terminal 15 is used to detect the presence or absence of the transport vehicle 10. When the memory unit 18 stores the weight of the transport vehicle 10 as a fixed value, the worker can omit the procedure of registering the weight of the transport vehicle 10. For example, the memory unit 18 stores the weight of a single transport vehicle 10 when only one transport vehicle 10 is used for loading work. Alternatively, the memory unit 18 stores the weight of the model according to its specifications when only multiple transport vehicles 10 of the same model are used for loading work. Alternatively, the memory unit 18 may store the heaviest weight of the transport vehicles 10 used for loading work.

The wireless terminal 15 may also be an external device of the elevator system 1.

Next, an example of a hardware configuration of the elevator system 1 will be described with reference to FIG. 3.
FIG. 3 is a hardware configuration diagram of a main part of the elevator system 1 according to the first embodiment.

Each function of the elevator system 1 may be realized by a processing circuit. The processing circuit includes at least one processor 100a and at least one memory 100b. The processing circuit may include at least one dedicated hardware 200 in addition to or in place of the processor 100a and memory 100b.

When the processing circuit includes a processor 100a and a memory 100b, each function of the elevator system 1 is realized by software, firmware, or a combination of software and firmware. At least one of the software and firmware is written as a program. The program is stored in the memory 100b. The processor 100a realizes each function of the elevator system 1 by reading and executing the program stored in the memory 100b.

The processor 100a is also called a CPU (Central Processing Unit), processing device, arithmetic device, microprocessor, microcomputer, or DSP. The memory 100b is composed of non-volatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, and EEPROM.

When the processing circuitry comprises dedicated hardware 200, the processing circuitry may be implemented, for example, as a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof.

Each function of the elevator system 1 can be realized by a processing circuit. Alternatively, each function of the elevator system 1 can be realized collectively by a processing circuit. Some of the functions of the elevator system 1 may be realized by dedicated hardware 200, and other parts may be realized by software or firmware. In this way, the processing circuit realizes each function of the elevator system 1 by dedicated hardware 200, software, firmware, or a combination of these.

Embodiment 2.
In the second embodiment, differences from the example disclosed in the first embodiment will be described in particular detail. For features not described in the second embodiment, any of the features of the example disclosed in the first embodiment may be adopted.

Figure 4 is a configuration diagram of an elevator system 1 according to embodiment 2.

The elevator system 1 includes a camera 21. The camera 21 is a device that captures images. The camera 21 is disposed, for example, in one or both of the hall 4 and the interior of the car 6. The camera 21 is connected to the network 12, for example, via the monitoring device 11, so that the captured images can be transmitted.

The support device 17 includes a determination unit 22. The determination unit 22 is a part that determines whether the transport vehicle 10 is in the car 6. In this example, the determination unit 22 determines whether the transport vehicle 10 is in the car 6 based on an image captured by the camera 21.

For example, the following information is displayed to the worker performing loading work in elevator system 1:

When the determination unit 22 determines that the transport vehicle 10 is loaded in the cage 6, the calculation unit 19 acquires the weight of the transport vehicle 10 stored in the memory unit 18 in association with the received identification information. The calculation unit 19 subtracts the acquired weight of the transport vehicle 10 from the loaded weight measured by the scale 8 to calculate the weight of the luggage 9 excluding the transport vehicle 10. The calculation unit 19 calculates a first loading rate as the ratio of the calculated weight of the luggage 9 to a first upper limit. The calculation unit 19 calculates a second loading rate as the ratio of the loaded weight measured by the scale 8, including the weight of the transport vehicle 10, to a second upper limit.

On the other hand, when the determination unit 22 determines that the transport vehicle 10 is not loaded in the cage 6, the calculation unit 19 acquires the weight of the transport vehicle 10 stored in the memory unit 18 in association with the received identification information. The calculation unit 19 calculates a first loading rate as a ratio of the load weight measured by the scale 8, which does not include the weight of the transport vehicle 10, to a first upper limit. The calculation unit 19 adds the acquired weight of the transport vehicle 10 to the load weight measured by the scale 8 to calculate the weight of the transport vehicle 10 and the luggage 9. The calculation unit 19 calculates a second loading rate as a ratio of the calculated weight, which includes the weight of the transport vehicle 10, to a second upper limit.

The output unit 20 outputs the first loading rate and the second loading rate calculated by the calculation unit 19 to the display device 16. The display device 16 displays the input first loading rate and second loading rate. The output unit 20 displays information on, for example, the display unit of the wireless terminal 15 as the display device 16. The display device 16 may be a device provided at the hall 4.

As described above, the support system 13 of the elevator system 1 according to the second embodiment includes a determination unit 22. The determination unit 22 determines whether the transport vehicle 10 is in the car 6. When the determination unit 22 determines that the transport vehicle 10 is not in the car 6, the calculation unit 19 calculates a first loading rate as the ratio of the load weight of the car 6 measured by the scale 8 to a first upper limit. In addition, at this time, the calculation unit 19 calculates a second loading rate as the ratio of the value obtained by adding the load weight of the car 6 measured by the scale 8 to the weight of the transport vehicle 10 stored in the memory unit 18 to a second upper limit.

This configuration allows workers, both inside and outside the car 6, to check both the percentage of the load weight relative to the upper limit when the car 6 is traveling, and the percentage of the load weight relative to the upper limit when luggage 9 is loaded from the landing 4 onto the car 6. This allows workers to more easily determine whether each of the multiple load weight conditions is being satisfied.

In addition, the determination unit 22 may determine whether the transport vehicle 10 is in the cage 6 without relying on the image captured by the camera 21. The determination unit 22 may determine whether the transport vehicle 10 has entered the cage 6, for example, based on a change in the load weight measured by the scale 8. For example, since there is usually a difference between the weight that a worker can carry manually and the weight of the transport vehicle 10, the determination unit 22 determines that the transport vehicle 10 has entered the cage 6 when the load weight measured by the scale 8 increases by more than a preset threshold. On the other hand, the determination unit 22 determines that the transport vehicle 10 has dismounted from the cage 6 when the load weight measured by the scale 8 decreases by more than a preset threshold. Alternatively, the determination unit 22 may determine whether the transport vehicle 10 has entered the cage 6 by wireless communication of the wireless terminal 15, for example. For example, when the transmitting device 14 transmits unique information unique to the transmitting device 14 by wireless signal, the wireless terminal 15 can wirelessly transmit the received unique information together with the identification information of the transport vehicle 10. In this case, when the wireless terminal 15 transmits unique information of the transmitting device 14 provided at the platform 4, the determination unit 22 may determine that the transport vehicle 10 is not in the car 6. On the other hand, when the wireless terminal 15 transmits unique information of the transmitting device 14 provided in the car 6, the determination unit 22 may determine that the transport vehicle 10 is in the car 6. Alternatively, the determination unit 22 may determine whether the transport vehicle 10 is in the car 6 by combining or switching between multiple determination criteria.

The camera 21 may also be an external device to the elevator system 1.

Embodiment 3.
In the third embodiment, differences from the examples disclosed in the first or second embodiment will be described in particular detail. For features not described in the third embodiment, any of the features of the examples disclosed in the first or second embodiment may be adopted.

Figure 5 is a configuration diagram of an elevator system 1 according to embodiment 3.

The support system 13 of the elevator system 1 is equipped with a measuring device 23.

The measuring device 23 is a device that measures the weight of the luggage 9 being transported by the transport vehicle 10. The measuring device 23 is provided on the transport vehicle 10. The measuring device 23 is, for example, a load checker. The measuring device 23 is connected to the wireless terminal 15 so as to be able to communicate, for example, by wire or wirelessly. The measurement results by the measuring device 23 are transmitted to the support device 17 via the wireless terminal 15 and the network 12. If the measuring device 23 is equipped with a wireless communication function, the measuring device 23 may communicate the measurement results without going through the wireless terminal 15.

The calculation unit 19 of the support device 17 calculates a first virtual loading rate and a second virtual loading rate. The first virtual loading rate is the ratio of the predicted value of the load weight of the luggage 9 loaded when the cage 6 travels, which includes the luggage 9 currently loaded and the luggage 9 to be loaded in the future, to a first upper limit. The second loading rate is the ratio of the predicted value of the load weight of the luggage 9 and the transport vehicle 10 when the luggage 9 is loaded into the cage 6, which includes the luggage 9 currently loaded and the luggage 9 to be loaded in the future, to a second upper limit.

For example, the following information is displayed to the worker performing loading work in elevator system 1:

When the determination unit 22 determines that the transport vehicle 10 is loaded in the cage 6, the calculation unit 19 acquires the weight of the transport vehicle 10 stored in the memory unit 18 in association with the received identification information. The calculation unit 19 subtracts the acquired weight of the transport vehicle 10 from the loaded weight measured by the scale 8 to calculate the weight of the luggage 9 excluding the transport vehicle 10. The calculation unit 19 calculates a first loading rate as the ratio of the calculated weight of the luggage 9 to a first upper limit. The calculation unit 19 calculates a second loading rate as the ratio of the loaded weight measured by the scale 8, including the weight of the transport vehicle 10, to a second upper limit.

The output unit 20 outputs the first loading rate and the second loading rate calculated by the calculation unit 19 to the display device 16. The display device 16 displays the input first loading rate and second loading rate.

On the other hand, when the determination unit 22 determines that the transport vehicle 10 is not loaded in the cage 6, the calculation unit 19 acquires the weight of the transport vehicle 10 stored in the memory unit 18 in association with the received identification information. The calculation unit 19 calculates a first loading rate as a ratio of the load weight measured by the scale 8, which does not include the weight of the transport vehicle 10, to a first upper limit. The calculation unit 19 adds the acquired weight of the transport vehicle 10 to the load weight measured by the scale 8 to calculate the weight of the transport vehicle 10 and the luggage 9. The calculation unit 19 calculates a second loading rate as a ratio of the calculated weight, which includes the weight of the transport vehicle 10, to a second upper limit.

When the determination unit 22 determines that the transport vehicle 10 is not loaded in the cage 6, the calculation unit 19 acquires the weight of the luggage 9 being transported by the transport vehicle 10 measured by the measuring device 23. The calculation unit 19 calculates the sum of the loaded weight measured by the scale 8, which does not include the weight of the transport vehicle 10, and the weight of the luggage 9 being transported by the transport vehicle 10 outside the cage 6, which is measured by the measuring device 23, as the predicted weight of the luggage 9, not including the weight of the transport vehicle 10, to be loaded into the cage 6. The calculation unit 19 calculates a first virtual loading rate as the ratio of the calculated predicted weight, not including the weight of the transport vehicle 10, to a first upper limit. The calculation unit 19 also calculates a second virtual loading rate as the ratio of the value obtained by adding the calculated predicted weight to the acquired weight of the transport vehicle 10 to a second upper limit.

The output unit 20 outputs the first loading rate and the second loading rate as well as the first virtual loading rate and the second virtual loading rate calculated by the calculation unit 19 to the display device 16. The display device 16 displays the input first loading rate and the second loading rate as well as the first virtual loading rate and the second virtual loading rate.

Figure 6 is an example of a display on the display device 16 according to embodiment 3.

The display device 16 simultaneously displays the first loading rate and the second loading rate and the first virtual loading rate and the second virtual loading rate, for example, by using a horizontal band graph. In this example, the display device 16 displays a horizontal band on the lower side whose left-right length represents the first upper limit. The display device 16 aligns its left end with the horizontal band and displays a horizontal band whose left-right length represents the first loading rate. Furthermore, the display device 16 aligns its left end with these horizontal bands displayed on the lower side and displays a horizontal band whose left-right length represents the first virtual loading rate. The display device 16 also displays a horizontal band whose left-right length represents the second upper limit on the upper side. The display device 16 aligns its left end with the horizontal band and displays a horizontal band whose left-right length represents the second loading rate. Furthermore, the display device 16 aligns its left end with these horizontal bands displayed on the upper side and displays a horizontal band whose left-right length represents the second virtual loading rate.

As described above, the elevator system 1 according to the third embodiment includes a measuring device 23. The measuring device 23 is provided on the transport vehicle 10. The measuring device 23 measures the weight of the baggage 9 being transported by the transport vehicle 10. The support system 13 of the elevator system 1 includes a determination unit 22. The determination unit 22 determines whether the transport vehicle 10 is in the cage 6. When the determination unit 22 determines that the transport vehicle 10 is not in the cage 6, the calculation unit 19 calculates a first loading rate as the ratio of the load weight of the cage 6 measured by the scale 8 to a first upper limit. Also, at this time, the calculation unit 19 calculates a second loading rate as the ratio of the value obtained by adding the load weight of the cage 6 measured by the scale 8 to the weight of the transport vehicle 10 stored in the memory unit 18 to a second upper limit. Furthermore, at this time, the calculation unit 19 calculates a first virtual loading rate as the ratio of the sum of the weight of the luggage 9 being transported by the transport vehicle 10 measured by the measuring device 23 and the load weight of the cage 6 measured by the scale 8 to a first upper limit. Also, at this time, the calculation unit 19 calculates a second virtual loading rate as the ratio of the sum of the weight of the luggage 9 being transported by the transport vehicle 10 measured by the measuring device 23 and the load weight of the cage 6 measured by the scale 8 plus the weight of the transport vehicle 10 stored in the memory unit 18 to a second upper limit. When the determination unit 22 determines that the transport vehicle 10 is not loaded on the cage 6, the output unit 20 outputs the first loading rate and second loading rate and the first virtual loading rate and second virtual loading rate calculated by the calculation unit 19 to the display device 16 for display.

This configuration allows the worker to check both the percentage of the load weight limit when the car 6 is traveling and the percentage of the load weight limit when the luggage 9 is loaded from the landing 4 onto the car 6 before loading the luggage 9 into the car 6. This prevents the need to go back and unload the luggage 9 after it is discovered that the load weight is exceeded after the luggage 9 has been loaded onto the car 6. This prevents a decrease in the efficiency of the loading operation.

The measuring device 23 may be an external device to the elevator system 1.
