Description

The present invention relates to elevator systems and programs, and in particular to the comfort of elevator users.

For example, when an employee returns from a departure point (e.g., a client's site) to a destination building such as their own company building, in the summer they may want to cool down as quickly as possible because they are sweating non-stop. Conversely, in the winter, their body may be freezing cold and they may want to warm up as quickly as possible.

For example, Patent Document 1 proposes an air conditioning control system that estimates a user's activity level based on step count information obtained from a pedometer carried by the user, and controls the air conditioner based on the result of determining whether the user is returning home from an outside outing from the activity level.

Patent Document 2 also proposes an elevator operating device that detects the temperatures inside multiple cars and sets a call to the car that has the desired temperature and that will arrive at the registered floor the earliest when the individual operates the hall button.

The following describes a preferred embodiment of the present invention based on the drawings.

Embodiment 1.
Fig. 1 is a block diagram showing the overall configuration of an elevator system according to the present embodiment. The elevator system according to the present embodiment is a system that is installed in a building such as a building, and manages and controls the operation of multiple elevator cars. Each floor of the building is provided with rooms where users of the building work.

Figure 1 shows a mobile terminal 10 and an operation management system 30. The mobile terminal 10 is carried by employees working in a building who use elevators (hereinafter referred to as "users") when they go out. The mobile terminal 10 is, for example, a portable information processing device such as a smartphone or tablet terminal. In this embodiment, the mobile terminal 10 can be realized with a general-purpose hardware configuration.

Figure 2 is a hardware configuration diagram of the mobile terminal 10 in this embodiment. As shown in Figure 2, the mobile terminal 10 is configured by connecting a CPU 21, a ROM 22, a RAM 23, a storage 24 as a memory means, a touch panel 25 as a user interface, a network interface (IF) 26 provided as a communication means, a GPS (Global Positioning System) 27 as a positioning means, and an acceleration sensor 28 to an internal bus 29.

The operation control system 30 manages the operation of multiple elevator cars installed in a building. In this embodiment, the operation control system 30 can be realized as a general-purpose hardware configuration of a server computer.

Figure 3 is a hardware configuration diagram of the traffic management system 30 in this embodiment. As shown in Figure 3, the traffic management system 30 in this embodiment is configured by connecting a CPU 41, a ROM 42, a RAM 43, a hard disk drive (HDD) 44 as a storage means, a network interface (IF) 45 provided as a communication means, and a user interface (UI) 46 including input means such as a mouse and a keyboard and display means such as a display to an internal bus 47.

Returning to FIG. 1, the mobile terminal 10 has a travel route identification unit 11, an action amount estimation unit 12, a boarding and alighting floor information acquisition unit 13, an information transmission unit 14, a display control unit 15, a travel route information storage unit 16, an action amount information storage unit 17, and a boarding and alighting floor information storage unit 18. Note that components that are not used in the description of this embodiment are omitted from the figure.

The travel route identification unit 11 detects the current location of the user at each point in time based on the longitude and latitude information measured by the GPS 27, and identifies the travel route from the departure point to the destination of the user carrying the mobile terminal 10 based on the transition of the detected current location. The travel route information storage unit 16 stores travel route information indicating the user's travel route identified by the travel route identification unit 11.

The activity amount estimation unit 12 acquires the acceleration measured by the acceleration sensor 28, and estimates the activity amount of the user carrying the mobile terminal 10 from the change in the acquired acceleration. The activity amount information storage unit 17 stores activity amount information indicating the activity amount estimated by the activity amount estimation unit 12. The activity amount will be described later.

The boarding and alighting floor information acquisition unit 13 acquires the floor where the user gets into the elevator car when he arrives at the building (hereinafter, the "departure floor") and the floor where he gets out of the car (hereinafter, the "arrival floor"). In this embodiment, the boarding and alighting floor information acquisition unit 13 accepts the departure floor and arrival floor input and specified by the user. The boarding and alighting floor information storage unit 18 stores boarding and alighting floor information including the departure floor and arrival floor acquired by the boarding and alighting floor information acquisition unit 13.

The information transmission unit 14 transmits each piece of information stored in each memory unit 16 to 18 to the operation management system 30 via the network interface 26. The information transmission unit 14 transmits the information after arriving at the building that is the destination of the trip, and before using the elevator.

The display control unit 15 controls the display of car-specific information, such as a car number, transmitted from the operation management system 30 on the touch panel 25. The car associated with the car number displayed on the touch panel 25 is the car that the user can use and is capable of providing the user with a comfortable space.

Note that the mobile terminal 10 carried by each user using the building has the components described above, so only one is shown in Figure 1 as a representative example.

Each of the components 11 to 15 in the mobile terminal 10 is realized by the cooperative operation of a computer built into the mobile terminal 10 and a program running on a CPU 21 mounted on the computer. In addition, each of the memory units 16 to 18 is realized by a storage 24 or RAM 23 mounted on the mobile terminal 10.

The operation control system 30 has an information receiving unit 31, a weather information acquiring unit 32, a heat load estimating unit 33, an in-car temperature acquiring unit 34, a car determining unit 35, a car control unit 36, and a display control unit 37. Note that components that are not used in the explanation of this embodiment are omitted from the figure.

The information receiving unit 31 receives information sent from the mobile terminal 10 via the network interface 45.

The weather information acquisition unit 32 acquires weather information from a weather information source such as the Japan Meteorological Agency. The information receiving unit 31 receives travel route information transmitted from the mobile terminal 10, but the weather information acquisition unit 32 in this embodiment only needs to acquire weather information on the travel route identified from the travel route information when the user is traveling.

The thermal load estimation unit 33 functions as an estimation means, and estimates the thermal load acting on the user when the user gets into the car by referring to the activity amount information acquired from the mobile terminal 10 and the weather information acquired by the weather information acquisition unit 32. In this embodiment, the thermal load estimation unit 33 will be described using an example in which the thermal load is estimated using only the temperature as weather information, but when referring to humidity, weather, etc., the weather information acquisition unit 32 needs to also acquire the humidity, weather, etc. that the thermal load estimation unit 33 refers to as weather information.

The car temperature acquisition unit 34 acquires the temperature inside the car of an elevator installed in a building as the car temperature. The car temperature acquisition unit 34 may directly or indirectly acquire the car temperature measured by a temperature sensor installed in each car. Alternatively, if the car temperature is controlled by an air conditioner, the car temperature acquisition unit 34 may acquire the set temperature for the air conditioner. In this embodiment, it is assumed that the car temperatures of multiple cars are not all the same temperature.

The cage determination unit 35 functions as a determination means, and determines the cage that provides a comfortable space for the user in terms of thermal environment by referring to the heat load of the user estimated by the heat load estimation unit 33 and the cage temperature of each cage acquired by the cage temperature acquisition unit 34.

The car control unit 36 controls the operation of the car so that the car determined by the car determination unit 35 arrives at the user's departure floor.

The display control unit 37 controls the display of information identifying the car determined by the car determination unit 35, such as the car number, on a display or the like. The display control unit 37 may cooperate with the display control unit 15 of the mobile terminal to control the display to be displayed on the touch panel 25 of the mobile terminal 10.

Each of the components 31 to 37 in the traffic management system 30 is realized by the cooperative operation of the computer that forms the traffic management system 30 and a program that runs on the CPU 41 installed in the computer.

The programs used in this embodiment can be provided not only by communication means, but also by storing them on a computer-readable recording medium such as a CD-ROM or USB memory. The programs provided from the communication means or recording medium are installed on a computer, and the various processes are realized by the computer's CPU sequentially executing the programs.

Here, we explain the terms "activity amount" and "thermal load" used in this embodiment.

First, the "amount of activity" estimated by the activity amount estimation unit 12 is an index that quantitatively indicates the amount of human movement. The greater the human movement, the greater the amount of activity. Also, the greater the amount of activity, the more likely the human body is to consume energy and generate heat. In this embodiment, the activity amount estimation unit 12 estimates the amount of human movement required to move from a departure point to a destination as the amount of activity. The destination is a building, or more specifically, an elevator hall that is the departure floor of a building. The departure point is a destination such as home or a client's office.

The amount of movement generally increases as the speed of movement increases. For example, when using one's own legs as a means of transportation, running will increase the amount of movement compared to walking if the same distance is traveled. When using one's own legs as a means of transportation, the longer the body is in motion, the more energy is consumed, so the amount of movement increases. When using a means of transportation such as a car as a means of transportation, people move less. Therefore, since the amount of movement is reduced, it is thought that there is almost no difference in the amount of movement even if the time spent using the means of transportation is longer or shorter. Also, when traveling the same distance, the amount of movement is greater when one uses one's own legs as a means of transportation than when using a means of transportation. The acceleration sensor 28 mounted on the mobile terminal 10 carried by the user can detect the movement speed and the amount of change in movement speed, so the means of transportation (legs (walking, running), bicycle, car, train, etc.) can be distinguished.

The term "thermal load" is generally defined as the total amount of heat (sensible heat load) or moisture (latent heat load) required to maintain a given temperature in a space such as a room, or the amount of heat or calories required to maintain a certain temperature and humidity level indoors. Thus, while "thermal load" is a term referring to the indoor environment, in this embodiment, the term "thermal load" is used to refer to the human body. In other words, in this embodiment, "thermal load" refers to the load on the human body in relation to thermal sensations such as hot and cold (hereinafter "thermal sensation"). Factors that affect the "thermal load" on the human body can be broadly divided into external factors and internal factors. Below, "thermal load", external factors, and internal factors will be explained using Figure 4.

Figure 4 is a conceptual diagram showing the relationship between the thermal load on the human body and external and internal factors in this embodiment. Thermal sensation varies from person to person, so the thermal load felt by a person may differ depending on the thermal environment in which they are placed, but this will be explained in general terms. Also, here, the temperature, which is one of the external factors, and the amount of activity, which is one of the internal factors, will be used as examples to explain. In Figure 4, the temperature and amount of activity take larger values as you move to the right of the drawing.

First, when the heat load on a person is small (or the person does not feel the heat load), the person feels comfortable. In contrast, when the heat load is relatively large, the person feels uncomfortable because they are too hot or too cold. Therefore, it is desirable to make the user comfortable by reducing the heat load on the user.

In terms of the relationship between heat load and temperature, in summer, when you feel cool, the heat load is small and you feel comfortable. As the temperature rises and it gets hotter, the heat load increases and the sense of discomfort increases. On the other hand, in winter, when you feel cold, the heat load is large and you feel uncomfortable. And as the temperature rises and it gets warmer, the heat load decreases and the sense of comfort increases.

In addition, in terms of the relationship between heat load and activity level, as activity level increases, the human body is more likely to generate heat. As a result, in the summer, the human body heats up and the heat load increases, leading to increased discomfort. On the other hand, in the winter, the heat load decreases as the human body generates heat, leading to increased comfort.

The above explanations have focused on the relationship between heat load and air temperature, and between heat load and activity level, but since people behave in a thermal environment that is determined by air temperature, etc., in reality, the heat load is determined by a combination of the thermal environment in which a person is placed and the amount of activity, as explained separately for summer and winter. The "thermal environment" refers to the thermal environment in which a person is present, and tends to depend mainly on external factors that act on the user from the outside, such as room temperature, outside air temperature, humidity, air currents, etc.

In the above explanation, temperature is used as an example of an external factor, but it is not necessary to limit it to temperature, and other external factors, such as humidity, wind direction, and wind volume, may also be considered. Also, the amount of activity is used as an example of an internal factor, but it is not necessary to limit it to the amount of activity alone, and for example, the amount of clothing worn may also be considered. In summer, the more clothing worn, the greater the heat load, and in winter, the more clothing worn, the smaller the heat load.

When the amount of clothing is taken into consideration, for example, a camera or other imaging means is installed at the elevator hall to capture an image of the user. Alternatively, an image of the user's clothing is captured using a camera on the mobile terminal 10 (not shown) and transmitted to the operation management system 30. The heat load estimation unit 33 may then analyze the captured image to estimate the amount of clothing. Alternatively, the user may input the amount of clothing via the mobile terminal 10.

The above explanation is a general theory. In reality, even in summer, if the air conditioning is too effective and the room temperature and other temperatures in a space drop too much, the heat load becomes large. Also, even in winter, if you are wearing too many clothes, the heat load becomes large.

Next, the operation of this embodiment will be described. Here, we will assume that the user visits a client and then returns to the building in which the company is located (hereinafter, also referred to as "the company" or "the company building"). In this case, the departure point is the client and the destination is the company building.

When the user returns to the company from a client's site, the travel route identification unit 11 is activated by performing a specific operation on the mobile terminal 10. When activated, the travel route identification unit 11 periodically acquires longitude and latitude information from the GPS 27. This provides the transition of the user's current location. This transition of the current location becomes the user's travel route. The travel route identification unit 11 then recognizes that the user has arrived at the destination when the user's current location becomes the company's location. When the travel route identification unit 11 arrives at the destination, it stores the transition of the current location at each time point in the travel route information storage unit 16 as travel route information indicating the travel route, and then terminates operation.

It is also possible to process as follows without the user inputting the departure time. That is, for example, the travel route identification unit 11 constantly acquires longitude and latitude information from the GPS 27 at regular intervals, and recognizes that the user has left the client premises when the user's movement is detected after a predetermined period of time or more has not been detected. In other words, the time when the user moves may be recognized as the departure time, and the current location at the departure time may be identified as the departure point.

When it is detected that the user has started moving from the departure point, the activity amount estimation unit 12 in the mobile terminal 10 constantly acquires acceleration from the acceleration sensor 28 from the time the user leaves the departure point until the user arrives at the destination. The activity amount estimation unit 12 then estimates the activity amount of the user carrying the mobile terminal 10 from the acquired change in acceleration. As described above, the activity amount estimation unit 12 can identify the user's means of transportation from the transition in acceleration. In addition, by processing to refer to past estimation results, etc., the activity amount estimation unit 12 can estimate the user's activity amount with higher accuracy. When the user arrives at the destination, the activity amount estimation unit 12 estimates the activity amount from the user's activity during movement, and stores activity amount information including the estimated activity amount in the activity amount information storage unit 17.

In this way, the movement route information and activity amount information are generated after the user arrives at the destination building, and at least before the user gets into the elevator car.

Before getting into the elevator car, the user performs a specific operation on the mobile terminal 10 to display an input screen for boarding and alighting floors on the touch panel, and inputs the departure floor and arrival floor from the input screen. When the boarding and alighting floor information acquisition unit 13 receives the departure floor and arrival floor input by the user, it stores the boarding and alighting floor information, including the departure floor and arrival floor, in the boarding and alighting floor information storage unit 18.

Once the travel route information, activity amount information, and boarding and alighting floor information are stored in each memory unit 16-18 in the manner described above, the information transmission unit 14 reads each piece of information from each memory unit 16-18 and transmits it to the traffic management system 30.

The traffic management system 30 starts processing by receiving information transmitted from the mobile terminal 10. The car call control processing performed by the traffic management system 30 is explained below with reference to the flowchart shown in FIG. 5.

The information receiving unit 31 receives the activity amount information and the movement route information transmitted from the mobile terminal 10 (step 101), and further receives the boarding and alighting floor information (step 102). In this embodiment, for the sake of convenience, the reception of the boarding and alighting floor information is separated from the reception of the activity amount information and the boarding and alighting floor information, but the three types of information may be received together.

Next, the weather information acquisition unit 32 refers to the travel route information to acquire weather information along the travel route during travel (step 103).

Next, the thermal load estimation unit 33 estimates the thermal environment in which the user was placed when moving (step 104). For example, by referring to meteorological information such as temperature, humidity, weather, and wind, it estimates whether the user was in a hot or cold environment when moving.

Next, the heat load estimation unit 33 estimates the heat load on the user by referring to the estimated thermal environment and activity amount information (step 105). In other words, the heat load estimation unit 33 estimates the heat load on the user by taking into account the external factor of the thermal environment and the internal factor of the activity amount.

For example, if traveling during the daytime in summer when it is sunny and the temperature is high, the heat load on the user is estimated to be large. However, when using public transportation such as trains or automobiles, it can be assumed that the user is inside a vehicle with the air conditioning running, so the heat load is estimated to be relatively small.

When the heat load estimation unit 33 estimates the heat load of the user, the car determination unit 35 acquires the car temperature of each car in operation from the car temperature acquisition unit 34 (step 106). Then, the car determination unit 35 refers to the heat load of the user and the car temperature of each car to determine the car that provides a comfortable space for the user in terms of thermal environment (step 107).

There are various methods for selecting from among multiple cars the car that is most comfortable for the user in terms of thermal environment. For example, a range of car interior temperatures to be selected as selection candidates according to the user's thermal load is preset, and from among the cars within that range, the car that is optimal for reducing the user's thermal load is selected, for example, the car with the lowest interior temperature in summer, or from among the selection candidates, the car that will arrive at the departure floor the earliest is selected, taking into account transport efficiency.

In addition, in this embodiment, floor boarding and alighting information including the departure floor and arrival floor of the user is obtained in advance. Therefore, the floor number on which the user is riding in the car can be known in advance. If the number of floors is relatively high, the time spent in the car will also be relatively long. Therefore, if the time spent in the car is long, the car may be selected so that the heat load can be reduced during that long time. For example, when the user rides on a relatively high number of floors, such as the first floor to the twentieth floor, the user will be in the car for a long time, so there is no need to rapidly reduce the heat load of the user. For this reason, for example, in winter, a car with a normal or relatively low temperature inside the car may be selected. On the other hand, when the user rides on a relatively low number of floors, such as the first floor to the third floor, the user will only be in the car for a short time, so it is desirable to rapidly reduce the heat load of the user. Therefore, for example, in winter, a car with a relatively high temperature inside the car is selected so that the user can be warmed in a short time. In this way, the car determination unit 35 may select a car that can reduce the heat load of a user more quickly the fewer floors the user is riding on in the car.

In addition, even if the heat load is the same, the car may be selected depending on the time of day. For example, when a person is leaving for work on a cold winter morning, he or she may want to warm up quickly, so a car with a higher internal temperature may be selected, taking into account that this is the time of leaving for work.

When the car determination unit 35 determines which car to call at the departure floor, the car control unit 36 controls the operation of the car so that the determined car is called to the departure floor (step 108). At the same time, the display control unit 37 transmits a car number that identifies the car to the mobile terminal 10 to notify the user of the car determined by the car determination unit 35 (step 109).

When the car number is transmitted from the traffic management system 30, the display control unit 15 in the mobile terminal 10 displays it on the touch panel 25. This allows the user to ride in the car with the car number displayed on the touch panel 25, i.e., a car that is comfortable for the user.

According to this embodiment, it is possible to select a car that provides a comfortable space for the user in terms of the thermal environment, and by using the selected car, the user can reduce the thermal load inside the car.

Embodiment 2.
6 is a diagram showing the overall configuration and block configuration of the elevator system according to the present embodiment. In the first embodiment, the user is made to operate the mobile terminal 10 to specify the departure floor at which the car will be boarded and the arrival floor at which the car will be alighted. However, the present embodiment is characterized in that the departure floor and the arrival floor can be automatically obtained without the user having to specify them.

To this end, the elevator system in this embodiment works in conjunction with an entrance/exit management system 50. The entrance/exit management system 50 is a system that manages the entrance and exit of users to and from a building and spaces within the building, such as rooms. The entrance/exit management system 50 has a card reader 51, a boarding/exiting floor information transmission unit 52, and a personal information storage unit 53. Note that components that are not used in the explanation of this embodiment are omitted from the figure.

The personal information storage unit 53 stores personal information of each user of the building. In the personal information, an identification code that identifies each user is associated with at least the floor in the building on which the room of the department to which the user belongs (hereinafter, the "room floor") is located.

Each user of the building carries an IC card 54. The IC card 54 records the user's identification code described above. When the IC card 54 is brought close to the card reader 51, it reads the identification code recorded on the IC card 54. The boarding and alighting floor information transmission unit 52, which will be described in detail later, generates boarding and alighting floor information when a user enters the building and transmits the generated boarding and alighting floor information to the operation management system 30.

The boarding and alighting floor information transmission unit 52 in the entrance and exit management system 50 is realized by the cooperative operation of a computer included in the entrance and exit management system 50 and a program running on a CPU installed in the computer. In addition, the personal information storage unit 53 is realized by a storage means such as an HDD installed in the entrance and exit management system 50.

As described above, in this embodiment, the entrance/exit management system 50 generates the boarding/alighting floor information, so the boarding/alighting floor information acquisition unit 13 and the boarding/alighting floor information storage unit 18 that the mobile terminal 10 has in embodiment 1 are not necessary.

Next, the operation of this embodiment will be described. In this embodiment, among the processes performed by the mobile terminal 10, the process of generating boarding and alighting floor information and transmitting it to the traffic management system 30 is not necessary. Also, the car call control process performed by the traffic management system 30 shown in FIG. 5 may be the same as in embodiment 1. However, in this embodiment, boarding and alighting floor information is obtained from the entrance and exit management system 50 rather than from the mobile terminal 10, so the content of the process in step 102 is different. Below, the process in step 102 that differs from embodiment 1 will be described.

When a user enters a building, the user holds the IC card 54 he or she is carrying over the card reader 51 at the building entrance. This causes the card reader 51 to read the user's identification code from the IC card 54.

When an identification code is sent from the card reader 51 at the building entrance, the boarding and alighting floor information sending unit 52 searches the personal information storage unit 53 to obtain the user's residential floor corresponding to the received identification code. The residential floor obtained here can be assumed to be the destination floor of the user who has returned to the company. The boarding and alighting floor information sending unit 52 then generates boarding and alighting floor information by setting the floor where the building entrance is located as the departure floor and the residential floor identified based on the identification code read from the IC card 54 as the arrival floor. The boarding and alighting floor information sending unit 52 then transmits the generated boarding and alighting floor information to the operation management system 30.

When the boarding and alighting floor information is transmitted from the boarding and alighting floor information transmission unit 52 in the manner described above, the car determination unit 35 in the operation control system 30 determines the car by referring to the boarding and alighting floor information as described above. The car number of the determined car may be displayed on a display unit provided at the entrance and exit gates provided in the entrance and exit control system 50, in addition to the mobile terminal 10 and the operation control system 30.

As described above, according to this embodiment, by linking with the entrance/exit management system 50, it is possible to determine the car based on the departure floor and arrival floor without requiring the user to input the departure floor and arrival floor.

In this embodiment, the floor on which the user will arrive is estimated by referencing the personal information contained in the entrance and exit management system 50. However, the personal information does not include information about customers of the company. Also, even employees may go directly to another room, such as a conference room, according to a schedule, rather than to their own room. Therefore, the floor on which the user will arrive may be estimated by linking with a system that manages the schedules of employees and visitors.

As mentioned above, in this embodiment, the departure point is explained as a customer's place of business, but this is not limited to this. For example, it can be applied to commuting from home. Also, if the departure point is a room in one's own company, it can be applied to car operation control when leaving work. In this case, since the building is usually air-conditioned, it is considered that car call control will be performed when the user's heat load is small.
