[0009] Embodiment 1 The configuration of an elevator car 1 (hereinafter also simply referred to as "car 1") in embodiment 1 will be described. Fig. 1 is a perspective view showing an outline of car 1 in embodiment 1. Fig. 2 is a schematic view of the inside of car 1 in embodiment 1 as seen from the entrance / exit side (the front side in the Y direction in Fig. 1).

[0010] The car 1 includes a car floor 2, a car ceiling 3, a car wall 4, and an elevator car handrail 5 (hereinafter simply referred to as "handrail 5"). The car floor 2, the car ceiling 3, and the car wall 4 form a car room 6.

[0011] The car floor 2 is disposed at the bottom of the car chamber 6. A carpet or the like is provided on the car floor 2. The car ceiling 3 is disposed at the top of the car chamber 6. A lighting fixture 3a is provided on the car ceiling 3. The lighting fixture 3a emits light to illuminate the inside of the car chamber 6.

[0012] The car wall 4 has two side walls 11a and 11b arranged on the side (X direction in FIG. 1), a front wall 12 arranged on the front side (rear side in Y direction in FIG. 1), and a front wall 13 arranged on the front side (near side in Y direction in FIG. 1). The side walls 11a and 11b face each other. The front wall 12 and front wall 13 face each other. The front wall 13 is provided with an entrance / exit 13a for people to enter and exit the car chamber 6. The car 1 may be configured so that an entrance / exit is also provided on the front wall 12, etc.

[0013] The handrail 5 is provided inside the car 1. The handrail 5 is provided on at least one side wall. In the first embodiment, the handrail 5 is provided on the side wall 11a. The handrail 5 is arranged so that its longitudinal direction is along the width direction of the side wall 11a (the Y direction in FIG. 1).

[0014] We will now explain the detailed configuration of the handrail 5. Figure 3 is a schematic diagram showing the appearance of the handrail 5 in embodiment 1, where Fig. 3(a) is a diagram of the handrail 5 seen from above (upper side in the Z direction in Fig. 2), Fig. 3(b) is a diagram of the handrail 5 seen from the front (right side in the X direction in Fig. 2), and Fig. 3(c) is a diagram of the handrail 5 seen from the side (rear side in the Y direction in Fig. 2).

[0015] The handrail 5 has a handrail main body 21 and a security device 22 (see FIG. 4) provided on the handrail main body 21. An attachment portion 21a is formed on the handrail main body 21, and this attachment portion 21a secures the handrail 5 to the side wall 11a. The length of the handrail main body 21 in the longitudinal direction (the left-right direction in FIG. 3(b)) can be adjusted appropriately according to the width direction of the wall on which it is installed (the side wall 11a in the first embodiment), and is, for example, 1 to 2 m.

[0016] A part of the components of the security device 22 is arranged so that it can be seen from the outside of the handrail main body 21. Specifically, the sensor 23 and light-emitting device 31 that make up the security device 22 are arranged along the longitudinal direction of the handrail main body 21. The sensor 23 and light-emitting device 31 are provided on the handrail main body 21 so that they are arranged facing the inside of the car 1 when the handrail 5 is fixed to the side wall 11a. The speaker 32 that makes up the security device 22 is arranged on the side of the handrail main body 21.

[0017] In the handrail 5, the sensors 23 are arranged along the longitudinal direction of the handrail main body 21, so blind spots are less likely to be formed and the security function is less likely to be interfered with. For example, if a security camera is installed inside the car 1 as a security function, blind spots are more likely to be formed. Furthermore, the security function of the security camera is interfered with if the lens is covered, for example. In contrast, in the handrail 5, the sensors 23 are arranged along the longitudinal direction of the handrail main body 21 and are installed along the width direction of the side wall 11a. In this way, since the sensors 23 are arranged over a wide area, blind spots are less likely to be formed and the security function is less likely to be interfered with compared to when a security camera is used.

[0018] FIG. 4 is a block diagram showing the functions of the security device 22 in the first embodiment. The security device 22 prevents crimes in which one person harms another person inside the car 1. The security device 22 has a sensor 23, a distance calculation unit 24, an abnormality determination unit 25, and an alarm device 30. The sensor 23 detects a person inside the car 1. The sensor 23 is, for example, a distance measurement sensor that measures the distance to a detected object. The distance calculation unit 24 calculates the distance between people based on the detection result of the sensor 23.

[0019] The abnormality determination unit 25 determines whether or not an abnormality has occurred based on the distance calculated by the distance calculation unit 24. The abnormality determination unit 25 determines that an abnormality has occurred when the distance calculated by the distance calculation unit 24 is equal to or less than a threshold value. The threshold value is the distance at which one person is expected to harm another person, and is, for example, 0.5 to 0.75 m. The threshold value can be set appropriately depending on the installation status and operating status of the elevator.

[0020] The alarm device 30 issues an alarm when the abnormality determination unit 25 determines that an abnormality has occurred. "Issuing an alarm" means at least one of issuing a caution or warning to people inside the car 1 and informing people outside the car 1 of an abnormality. By issuing an alarm, the alarm device 30 prevents crime by deterring the actions of people who intend to cause harm, by warning people who are about to be harmed, or by reporting the incident to the outside.

[0021] The alarm device 30 includes a light-emitting device 31, a speaker 32, a communication device 33, and an alarm control unit 34. The light-emitting device 31 emits light to alert or warn people inside the car 1. The light-emitting device 31 emits light, for example, in red. The speaker 32 emits sound to alert or warn people inside the car 1. The sound emitted by the speaker 32 is, for example, a buzzer sound or a warning message. The communication device 33 communicates with the outside of the car 1. The communication device 33 communicates with devices outside the car 1 to notify people outside the car 1 of an abnormality inside the car 1. The communication device 33 is connected to, for example, a security company that guards the elevator equipped with the car 1 or a terminal installed at the elevator hall. The communication device 33 requests rescue by reporting to the security company. The communication device 33 also notifies a terminal installed at the elevator hall to notify people around (for example, people waiting at the hall) that an abnormality has occurred inside the car 1 and urges them to take prompt action. The alarm control unit 34 controls the operations of the light emitting device 31 , the speaker 32 , and the communication device 33 .

[0022] The hardware configuration of the control functions (distance calculation unit 24, abnormality determination unit 25, and alarm control unit 34) of the security device 22 in embodiment 1 will be described. Fig. 5 is a block diagram showing the hardware configuration of the control functions of the security device 22 in embodiment 1. The control functions of the security device 22 are realized by a computer such as a personal computer or a microcontroller.

[0023] The security device 22 includes a bus 101, a processor 102, a memory 103, an interface 104, and a secondary storage device 105. The processor 102, the memory 103, the interface 104, and the secondary storage device 105 are connected to each other via the bus 101.

[0024] The processor 102 is, for example, a CPU (Central Processing Unit). The processor 102 loads an operating program stored in the secondary storage device 105 into the memory 103 and executes it, thereby realizing each function of the security device 22.

[0025] The memory 103 is a main storage device configured by, for example, a RAM (Random Access Memory). The memory 103 stores a program that the processor 102 reads from the secondary storage device 105. The memory 103 functions as a work memory when the processor 102 executes the program.

[0026] The interface 104 is an I / O (Input / Output) interface such as a serial port, a USB (Universal Serial Bus) port, a network interface, etc. The interface 104 is used to communicate with other devices.

[0027] The secondary storage device 105 is, for example, a flash memory, a hard disk drive (HDD), or a solid state drive (SSD). The secondary storage device 105 stores various information necessary for the operation of the security device 22 and programs executed by the processor 102.

[0028] The operation of the security device 22 will be described below. First, the configuration for grasping the situation inside the car 1 will be described. Fig. 6 is an explanatory diagram for explaining the configuration for detecting a person inside the car 1 in embodiment 1, Fig. 6(a) is a schematic diagram of the car room 6 as seen from above (upper side in the Z direction in Fig. 2), and Fig. 6(b) is an explanatory diagram for explaining a two-dimensional array for detecting an occupied area.

[0029] The security device 22 divides the car room 6 into a grid pattern to grasp the situation inside the car 1. The size of one division is, for example, 1 cm. 2 Note that Figure 6(b) is a schematic diagram, and the number of grids does not necessarily represent the actual number of grids.

[0030] Next, a configuration for detecting a person inside the car 1 in the first embodiment will be described. An example will be described in which there are two people, person 40A and person 40B, inside the car 1. Fig. 7 is an explanatory diagram for explaining the configuration for detecting a person inside the car 1 in the first embodiment, Fig. 7(a) is a schematic diagram of the car room 6 as seen from above (upper side in the Z direction in Fig. 2), Fig. 7(b) is a schematic diagram showing distance data acquired by the sensor 23, and Fig. 7(c) is a schematic diagram showing occupied area data.

[0031] As shown in FIG. 7(a), there are people 40A and 40B inside the car 1. In this situation, the sensor 23 acquires the distance data shown in FIG. 7(b). As shown in FIG. 7(b), the measured distance is shorter where people 40A and 40B are present. Based on this distance data, the distance calculation unit 24 generates occupied area data. As shown in FIG. 7(c), the occupied area data includes occupied area 41A and occupied area 41B. Occupied area 41A corresponds to person 40A, and occupied area 41B corresponds to person 40B. The occupied area data makes it possible to determine whether there are people, their positions inside the car 1, the distance between people, etc.

[0032] A description will now be given of the alarm operation by the security device 22 in embodiment 1. Fig. 8 is a flowchart showing the alarm operation by the security device 22 in embodiment 1.

[0033] In step S11, the distance between people in the car 1 is calculated. The sensor 23 detects people in the car 1 and acquires distance data. The distance calculation unit 24 generates occupied area data based on this distance data. The distance calculation unit 24 calculates the center of gravity for each occupied area included in the occupied area data and calculates the distance between the centers of gravity. The distance between people in the car 1 is calculated from the calculated distance between the centers of gravity. The distance calculation unit 24 transmits the calculated distance to the abnormality determination unit 25.

[0034] In step S12, it is determined whether the distance between people in the car 1 is equal to or less than a threshold value. The abnormality determination unit 25 determines whether the distance transmitted from the distance calculation unit 24 is equal to or less than the threshold value. If it is determined to be equal to or less than the threshold value (Yes in step S12), the process proceeds to step S13, and if it is determined not to be equal to or less than the threshold value (No in step S12), the process proceeds to step S11.

[0035] If it is determined that the detected value is not equal to or less than the threshold value (No in step S12), the cycle of steps S11 and S12 is repeated at a predetermined time interval. This time interval may be within a range that allows the movement of people in the elevator car 1 to be continuously and appropriately monitored, and may be, for example, one second. This time interval can be set appropriately depending on the installation and operating conditions of the elevator.

[0036] In step S13, an alarm is issued. The alarm control unit 34 transmits activation instructions to the light-emitting device 31, the speaker 32, and the communication device 33. Upon receiving this instruction, the light-emitting device 31 emits light and the speaker 32 emits sound. The communication device 33 notifies the security company that an abnormality has occurred, and also notifies a terminal installed at the elevator hall.

[0037] Although the configuration in which the distance calculation unit 24 calculates the distance between people at a certain point in time and transmits the calculated distance to the abnormality determination unit 25 has been described, the configuration is not limited thereto, and the distance calculation unit 24 may also be configured to calculate the ratio of the distance between people before and after a change and transmit the ratio to the abnormality determination unit 25. When using the ratio of the distance between people before and after a change in the distance, the abnormality determination unit 25 compares the ratio of the distance before and after the change transmitted from the distance calculation unit 24 with a threshold value. For example, if the distance between people is 1 m at a certain point in time and 0.4 m a few seconds later, the ratio of the distance before and after the change in the distance is 40%. If the threshold value is 50%, the rate of change in the distance is equal to or less than the threshold value, and therefore the abnormality determination unit 25 determines that an abnormality has occurred.

[0038] In the first embodiment, the security device 22 is configured to issue an alarm when the distance between people in the car 1 is equal to or less than a threshold value. Generally, people stay at a certain distance from other people to ensure personal space. If people get closer to each other than the normally expected distance in the car 1, there is a risk that they may attempt to cause harm. Therefore, the security device 22 of the first embodiment prevents crime by issuing an alarm when the distance between people is equal to or less than a threshold value.

[0039] Embodiment 2 The configuration of the security device 42 in embodiment 2 will be described. Fig. 9 is a block diagram showing the functions of the security device 42 in embodiment 2. Embodiment 2 differs from embodiment 1 in that the security device 42 further includes an individual group identification unit 46. The same components as those in embodiment 1 are given the same reference numerals, and their description will be omitted.

[0040] The security device 42 includes a sensor 23 , a distance calculation unit 24 , an abnormality determination unit 25 , an individual / group identification unit 46 , and an alarm device 30 .

[0041] The individual / group identification unit 46 identifies whether the people in car 1 are individual users or group users. An "individual user" refers to a person using the elevator alone. A "group user" refers to a person using the elevator in a group of two or more people, such as a duo or trio. For example, if there are two people in car 1, "person A" and "person B," who is a different person from "person A," each of "person A" and "person B" is an "individual user." Alternatively, if there are three people in car 1, "person A" and "duo C," who are different from "person A," then "person A" is an "individual user" and "duo C" is a "group user."

[0042] In embodiment 2, the abnormality determination unit 25 determines that an abnormality has occurred when the identification result of the individual group identification unit 46 does not include any users of the group and the distance calculated by the distance calculation unit 24 is less than or equal to a threshold value.

[0043] The hardware configuration of the control functions (distance calculation unit 24, abnormality determination unit 25, individual / group identification unit 46, and alarm control unit 34) of the security device 42 in embodiment 2 is the same as the hardware configuration of the control functions of the security device 22 in embodiment 1.

[0044] A configuration for detecting people in the car 1 in the second embodiment will be described. An example will be described in which there are three people in the car 1, namely, person 40A, person 40B, and person 40C, and person 40A is an individual user, while person 40B and person 40C are a pair of users who are strangers to person 40A.

[0045] Figure 10 is an explanatory diagram explaining the configuration for detecting people inside the car 1 in embodiment 2, where Figure 10(a) is a schematic diagram of the car room 6 viewed from above (upper side in the Z direction in Figure 2), Figure 10(b) is a schematic diagram showing distance data acquired by the sensor 23, and Figure 10(c) is a schematic diagram showing occupied area data.

[0046] As shown in FIG. 10(a), there are people 40A, 40B, and 40C in the car 1. People 40B and 40C have a known relationship. Therefore, people 40B and 40C are located close to each other. Person 40A is a stranger who has an unknown relationship with people 40B and 40C. Therefore, person 40A is located farther away from people 40B and 40C than the distance between people 40B and 40C.

[0047] In this situation, the sensor 23 acquires distance data as shown in FIG. 10(b). As shown in FIG. 10(b), the measured distance is shorter where people 40A, 40B, and 40C are present. Occupation area data is generated based on this distance data. As shown in FIG. 10(c), the occupation area data includes occupation area 41A and occupation area 41BC. Occupation area 41A corresponds to person 40A, and occupation area 41BC corresponds to the pair of people 40B and 40C. People who are closer than a predetermined distance from the beginning are grouped together in their occupation areas. Occupation area 41BC is larger than occupation area 41A. The occupation area data makes it possible to determine whether there are people, their positions within the car 1, the distance between the people, and whether the people in the car 1 are individual users or a group of users.

[0048] A description will now be given of the alarm operation by the security device 42 in embodiment 2. Fig. 11 is a flowchart showing the alarm operation by the security device 42 in embodiment 2.

[0049] In step S21, the person in the car 1 is identified as an "individual user" or a "group user." The sensor 23 acquires distance data. The distance calculation unit 24 generates occupied area data based on this distance data. The individual / group identification unit 46 identifies whether the person is an "individual user" or a "group user" based on the occupied area data. The individual / group identification unit 46 identifies the person as an "individual user" if the occupied area is smaller than a predetermined area, and identifies the person as a "group user" if the occupied area is equal to or larger than the predetermined area. The individual / group identification unit 46 transmits the identification result of whether the person is an "individual user" or a "group user" to the abnormality determination unit 25. The predetermined area is set, for example, based on data obtained by previously analyzing the area of ​​an occupied area that could correspond to one person.

[0050] In step S22, it is determined whether or not the people in car 1 include a "group user." The abnormality determination unit 25 determines whether or not the people in car 1 include a "group user" based on the identification result transmitted from the individual / group identification unit 46. If a "group user" is not included in car 1 (No in step S22), the process proceeds to step S23, and if a "group user" is included in car 1 (Yes in step S22), the process ends.

[0051] In step S23, the distance between people in the car 1 is calculated. The sensor 23 detects people in the car 1 and acquires distance data. The distance calculation unit 24 generates occupied area data based on this distance data. The distance calculation unit 24 calculates the center of gravity for each occupied area included in the occupied area data and calculates the distance between the centers of gravity. The distance between people in the car 1 is calculated from the calculated distance between the centers of gravity. The distance calculation unit 24 transmits the calculated distance to the abnormality determination unit 25.

[0052] In step S24, it is determined whether the distance between people in the car 1 is equal to or less than a threshold value. The abnormality determination unit 25 determines whether the distance between people calculated by the distance calculation unit 24 is equal to or less than a predetermined value. If it is determined to be equal to or less than the threshold value (Yes in step S24), the process proceeds to step S25, and if it is determined not to be equal to or less than the threshold value (No in step S24), the process proceeds to step S23.

[0053] In step S25, an alarm is issued. The alarm control unit 34 transmits activation instructions to the light-emitting device 31, the speaker 32, and the communication device 33. Upon receiving this instruction, the light-emitting device 31 emits light and the speaker 32 emits sound. The communication device 33 notifies the control center that manages the elevator that an abnormality has occurred, and also notifies a terminal installed at the elevator hall.

[0054] If it is determined that the detected value is not equal to or less than the threshold value (No in step S24), the cycle of steps S23 and S24 is repeated at a predetermined time interval. This time interval may be within a range that allows the movement of people in the elevator car 1 to be continuously and appropriately monitored, and may be, for example, one second. This time interval can be set appropriately depending on the installation and operating conditions of the elevator.

[0055] In the second embodiment, the system is configured to issue an alarm in a predetermined case when there is no group of users in the car 1. In other words, the system is configured not to issue an alarm when there is a group of users in the car 1. It is believed that crimes that harm others are less likely to occur among a group of users (for example, friends or parents and children). Furthermore, crimes in which individual users harm other individual users are more likely to occur in the car 1. It is believed that crimes are less likely to occur when there is a group of users in the car 1 compared to when there are only individual users. For this reason, by not issuing an alarm when there is a group of users in the car 1, it is possible to issue an alarm in a more accurate situation without reducing the crime prevention function.

[0056] Embodiment 3 The configuration of security device 52 in embodiment 3 will be described. Fig. 12 is a block diagram showing the functions of security device 52 in embodiment 3. Embodiment 3 differs from embodiment 1 in that security device 52 further includes a number of people calculation unit 47. The same components as in embodiment 1 are given the same reference numerals, and their description will be omitted.

[0057] The security device 52 includes a sensor 23 , a distance calculation unit 24 , an abnormality determination unit 25 , a number of people calculation unit 47 , and an alarm device 30 .

[0058] The number of people calculation unit 47 calculates the number of people in the car 1. The number of people calculation unit 47 calculates the number of people in the car 1 based on, for example, the occupied area data and the area per person. The area per person can be set in advance based on a preliminary experiment or the like.

[0059] In embodiment 3, the abnormality determination unit 25 determines that an abnormality has occurred when the number of people calculated by the number of people calculation unit 47 is within a predetermined range and the distance calculated by the distance calculation unit 24 is equal to or less than a threshold value.

[0060] The predetermined range is set appropriately based on the number of passengers and the size of the car 1. The predetermined range is, for example, 0 to 5 people, preferably 2 to 5 people, more preferably 2 to 3 people, and even more preferably 2 people.

[0061] The hardware configuration of the control functions (distance calculation unit 24, abnormality determination unit 25, number of people calculation unit 47, and alarm control unit 34) of the security device 42 in embodiment 3 is the same as the hardware configuration of the control functions of the security device 22 in embodiment 1.

[0062] A description will now be given of the alarm operation by the security device 52 in embodiment 3. Fig. 13 is a flowchart showing the alarm operation by the security device 52 in embodiment 3.

[0063] In step S31, the number of people in car 1 is calculated. Sensor 23 detects people in car 1 and acquires distance data. Distance calculation unit 24 generates occupied area data based on this distance data. Number of people calculation unit 47 calculates the number of people in car 1 based on the occupied area data. Number of people calculation unit 47 calculates the area of ​​the occupied area from the occupied area data, and calculates the number of people in car 1 based on this area and a preset area per person. Number of people calculation unit 47 transmits the calculated number of people to abnormality determination unit 25.

[0064] In step S32, it is determined whether the number of people is within a predetermined range. Abnormality determination unit 25 determines whether the calculated number of people is within the predetermined range based on the number of people transmitted from headcount calculation unit 47. If the calculated number of people is within the predetermined range (Yes in step S32), the process proceeds to step S33, and if it is not within the predetermined range (No in step S32), the process ends.

[0065] In step S33, the distance between people in the car 1 is calculated. The sensor 23 detects people in the car 1 and acquires distance data. The distance calculation unit 24 generates occupied area data based on this distance data. The distance calculation unit 24 calculates the center of gravity for each occupied area included in the occupied area data and calculates the distance between the centers of gravity. The distance between people in the car 1 is calculated from the calculated distance between the centers of gravity. The distance calculation unit 24 transmits the calculated distance to the abnormality determination unit 25.

[0066] In step S34, it is determined whether the distance between people in the car 1 is equal to or less than a threshold value. The abnormality determination unit 25 determines whether the distance between people calculated by the distance calculation unit 24 is equal to or less than the threshold value. If it is determined to be equal to or less than the threshold value (Yes in step S34), the process proceeds to step S35, and if it is determined not to be equal to or less than the threshold value (No in step S34), the process proceeds to step S33.

[0067] In step S35, an alarm is issued. The alarm control unit 34 transmits activation instructions to the light-emitting device 31, the speaker 32, and the communication device 33. Upon receiving this instruction, the light-emitting device 31 emits light and the speaker 32 emits sound. The communication device 33 notifies the control center that manages the elevator that an abnormality has occurred, and also notifies a terminal installed at the elevator hall.

[0068] If it is determined that the detected value is not equal to or less than the threshold value (No in step S34), the cycle of steps S33 and S34 is repeated at a predetermined time interval. This time interval may be within a range that allows for continuous and appropriate monitoring of the movement of people in the elevator car 1, and may be, for example, one second. This time interval can be set appropriately depending on the installation and operating conditions of the elevator.

[0069] In the third embodiment, the alarm device 30 is configured to issue an alarm under certain circumstances when the number of people in the car 1 is within a predetermined range. In other words, the alarm device 30 is configured not to issue an alarm if the number of people in the car 1 is outside the predetermined range. When there are a certain number of people in the car 1, it is thought that crimes are less likely to occur because the eyes of others act as a deterrent. Furthermore, when there are many people in the car 1, people are closer to each other, which may lead to a false alarm. Specifically, when there are many people in the car 1, people may approach others without criminal intent. In this case, issuing an alarm by the alarm device 30 is unintended and would result in a false alarm. On the other hand, when the number of people in the car 1 is one or less, no actions that would harm others are likely to occur. Therefore, by not issuing an alarm when the number of people in the car 1 is outside the predetermined range, an alarm can be issued in a more accurate situation without reducing the security function.

[0070] Embodiment 4 The configuration of the security device 62 in embodiment 4 will be described. Fig. 14 is a block diagram showing the functions of the security device 62 in embodiment 4. Embodiment 4 differs from embodiment 1 in that the security device 62 further includes a speed detector 48. The same components as in embodiment 1 are given the same reference numerals, and their description will be omitted.

[0071] The security device 62 has a sensor 23, a distance calculation unit 24, an abnormality determination unit 25, a speed detector 48, and an alarm device 30. The speed detector 48 detects the speed at which the car 1 moves. The speed detector 48 is, for example, a speed sensor or an acceleration sensor.

[0072] In embodiment 4, the abnormality determination unit 25 determines that an abnormality has occurred when the speed detected by the speed detector 48 is equal to or greater than a predetermined speed and the distance calculated by the distance calculation unit 24 is equal to or less than a threshold value.

[0073] A description will now be given of the alarm operation by the security device 62 in embodiment 4. Fig. 15 is a flowchart showing the alarm operation by the security device 62 in embodiment 4.

[0074] In step S41, the speed of the car 1 is measured. The speed detector 48 measures the speed at which the car 1 moves. The speed detector 48 transmits the detection result to the abnormality determination unit 25.

[0075] In step S42, it is determined whether the speed is equal to or greater than a predetermined speed. Abnormality determination unit 25 determines whether the detected speed is equal to or greater than a predetermined speed based on the detection result transmitted from speed detector 48. If the detected speed is equal to or greater than the predetermined speed (Yes in step S42), the process proceeds to step S43, and if the detected speed is lower than the predetermined speed (No in step S42), the process ends.

[0076] The predetermined speed is set appropriately based on the speed of car 1 during normal operation, etc. For example, assume that the speed of car 1 changes in four stages: when stopped (V0), when starting to move (V1), when moving at a constant speed (V2), and when about to stop (V3). V2 is the largest speed, followed by V1 and V3, and V0 is the smallest (V0 is zero). In this case, the predetermined speed is set to a value equivalent to V2 (a value slightly smaller than V2).

[0077] In step S43, the distance between people in the car 1 is calculated. The sensor 23 detects people in the car 1 and acquires distance data. The distance calculation unit 24 generates occupied area data based on this distance data. The distance calculation unit 24 calculates the center of gravity for each occupied area included in the occupied area data and calculates the distance between the centers of gravity. The distance between people in the car 1 is calculated from the calculated distance between the centers of gravity. The distance calculation unit 24 transmits the calculated distance to the abnormality determination unit 25.

[0078] In step S44, it is determined whether the distance between people in the car 1 is equal to or less than a threshold. The abnormality determination unit 25 determines whether the distance between people calculated by the distance calculation unit 24 is equal to or less than the threshold. If it is determined to be equal to or less than the threshold (Yes in step S44), the process proceeds to step S45, and if it is determined not to be equal to or less than the threshold (No in step S44), the process proceeds to step S43.

[0079] In step S45, an alarm is issued. The alarm control unit 34 transmits activation instructions to the light-emitting device 31, the speaker 32, and the communication device 33. Upon receiving this instruction, the light-emitting device 31 emits light and the speaker 32 emits sound. The communication device 33 notifies the control center that manages the elevator that an abnormality has occurred, and also notifies a terminal installed at the elevator hall.

[0080] If it is determined that the detected value is not equal to or less than the threshold value (No in step S44), the cycle of steps S43 and S44 is repeated at a predetermined time interval. This time interval may be within a range that allows the movement of people in the elevator car 1 to be continuously and appropriately monitored, and may be, for example, one second. This time interval can be set appropriately depending on the installation and operating conditions of the elevator.

[0081] In the fourth embodiment, the system is configured to issue an alarm in a specified case when the speed at which the car 1 is moving is equal to or greater than a predetermined speed. In other words, the system is configured not to issue an alarm when the speed at which the car 1 is moving is slower than the predetermined speed. The speed at which the car 1 moves slows when the car 1 is stopped and before and after the car stops. When the car 1 is stopped and before and after the car stops, people inside the car 1 move to get on or off. As a result, people inside the car 1 may move toward other people without criminal intent. In this case, issuing an alarm by the alarm device 30 is unintended and would be a malfunction. Therefore, by not issuing an alarm when the speed at which the car 1 is moving is slower than a predetermined speed, an alarm can be issued in more accurate situations without reducing the security function.

[0082] Embodiment 5 The configuration of the security device 72 in embodiment 5 will be described. Fig. 16 is a block diagram showing the functions of the security device 72 in embodiment 5. Embodiment 5 differs from embodiment 1 in that the security device 72 further includes a registrant determination unit 49. The same components as in embodiment 1 are given the same reference numerals, and their description will be omitted.

[0083] The security device 72 includes a sensor 23 , a distance calculation unit 24 , an abnormality determination unit 25 , a registrant determination unit 49 , and an alarm device 30 .

[0084] The registrant determination unit 49 determines whether the person in the car 1 is a registrant. The registrant determination unit 49 determines whether the person in the car 1 is a registrant based on registrant information stored in a communication device (e.g., a mobile phone or an electronic tag) carried by the person in the car 1, for example, in a bag or pocket, and transmits the determination result to the abnormality determination unit 25. For example, it is assumed that people associated with an apartment building (e.g., residents) normally use the elevators installed in the apartment building. According to the apartment building management rules, the associated people record registrant information in advance using communication devices as a medium. On the other hand, people other than the associated people do not carry media on which registrant information is recorded. If the specified registrant information is acquired, the user is a registrant, and if the specified registration information is not acquired, the user is not a registrant. This makes it possible to distinguish whether the person in the car 1 is a normally expected user or an external user who is not normally expected.

[0085] In embodiment 5, the abnormality determination unit 25 determines that an abnormality has occurred when the determination result of the registrant determination unit 49 includes a user who is not a registrant and the distance calculated by the distance calculation unit 24 is less than or equal to a threshold value.

[0086] The hardware configuration of the control functions (distance calculation unit 24, abnormality determination unit 25, registrant determination unit 49, and alarm control unit 34) of the security device 72 in embodiment 5 is the same as the hardware configuration of the control functions of the security device 22 in embodiment 1.

[0087] A configuration for detecting people inside the car 1 in the fifth embodiment will be described. An example will be described in which there are three people in the car 1, namely, person 40A, person 40B, and person 40C, and person 40A is an individual user, while person 40B and person 40C are a pair of users who are strangers to person 40A.

[0088] A description will now be given of the alarm operation by the security device 72 in embodiment 5. Fig. 17 is a flowchart showing the alarm operation by the security device 72 in embodiment 5.

[0089] In step S51, it is determined whether or not the person in the car 1 is a registered person. The registered person determination unit 49 attempts to acquire registered person information from communication devices owned by the people in the car 1. Based on the acquired results, the registered person determination unit 49 determines whether or not each person in the car 1 is a registered person. The registered person determination unit 49 transmits the determination result as to whether or not the person is a registered person to the abnormality determination unit 25.

[0090] In step S52, it is determined whether or not there is a user who is not a registered person among the people in car 1. The abnormality determination unit 25 determines whether or not there is a user who is not a registered person in car 1 based on the determination result transmitted from the registered person determination unit 49. If there is a user who is not a registered person in car 1 (Yes in step S52), the process proceeds to step S53, and if there is no user who is not a registered person in car 1 (No in step S52), the process ends.

[0091] In step S53, the distance between people in the car 1 is calculated. The sensor 23 detects people in the car 1 and acquires distance data. The distance calculation unit 24 generates occupied area data based on this distance data. The distance calculation unit 24 calculates the center of gravity for each occupied area included in the occupied area data and calculates the distance between the centers of gravity. The distance between people in the car 1 is calculated from the calculated distance between the centers of gravity. The distance calculation unit 24 transmits the calculated distance to the abnormality determination unit 25.

[0092] In step S54, it is determined whether the distance between people in the car 1 is equal to or less than a threshold value. The abnormality determination unit 25 determines whether the distance between people calculated by the distance calculation unit 24 is equal to or less than the threshold value. If it is determined to be equal to or less than the threshold value (Yes in step S54), the process proceeds to step S55, and if it is determined not to be equal to or less than the threshold value (No in step S54), the process proceeds to step S53.

[0093] In step S55, an alarm is issued. The alarm control unit 34 transmits activation instructions to the light-emitting device 31, the speaker 32, and the communication device 33. Upon receiving this instruction, the light-emitting device 31 emits light and the speaker 32 emits sound. The communication device 33 notifies the control center that manages the elevator that an abnormality has occurred, and also notifies a terminal installed at the elevator hall.

[0094] If it is determined that the detected value is not equal to or less than the threshold value (No in step S54), the cycle of steps S53 and S54 is repeated at a predetermined time interval. This time interval may be within a range that allows the movement of people in the elevator car 1 to be continuously and appropriately monitored, and may be, for example, one second. This time interval can be set appropriately depending on the installation and operating conditions of the elevator.

[0095] In the fifth embodiment, the system is configured to issue an alarm in a predetermined case when there is a user who is not a registered user in the car 1. In other words, the system is configured not to issue an alarm if all the people in the car 1 are registered users. Users who regularly use the elevator in question (for example, residents of the apartment building where the elevator is located, or workers who work in the building where the elevator is located) are considered less likely to commit crimes. When only regular users are present in the car 1, crimes are considered less likely to occur compared to when there are users who do not regularly use the elevator (for example, outsiders). For this reason, by not issuing an alarm when all the people in the car 1 are registered users, it is possible to issue an alarm in a more accurate situation without reducing the security function.

[0096] Embodiment 6 The configuration of an elevator car 71 in embodiment 6 will be described. Figure 18 is a schematic diagram of the inside of an elevator car 71 in embodiment 6 as seen from the entrance / exit side. Embodiment 6 differs from embodiment 1 in that elevator car 71 is provided with handrails 5 on each of two side walls 11a and 11b. The same components as in embodiment 1 are given the same reference numerals, and their description will be omitted.

[0097] The elevator car 71 has two handrails 5. The two handrails 5 are provided on the side wall 11a and the side wall 11b, respectively. The two handrails 5 are arranged so that their longitudinal directions are aligned with the width directions of the side walls 11a and 11b. The two handrails 5 are arranged facing each other. The two handrails 5 transmit and receive occupied area data to and from each other.

[0098] The configuration for detecting a person in the car 1 in the sixth embodiment will be described. The description will be made taking as an example a case where two people, a person 40A and a person 40B, are present in the car 1. FIG. 19 is a schematic diagram of the car room 6 in the sixth embodiment as viewed from above (the upper side in the Z direction in FIG. 18). FIG. 20 is an explanatory diagram for explaining the configuration for detecting a person in the car 1 in the sixth embodiment, in which FIG. 20(a) is a schematic diagram showing distance data acquired by the sensor 23 of the handrail 5 provided on the side wall 11a, FIG. 20(b) is a schematic diagram showing occupied area data corresponding to FIG. 20(a), FIG. 20(c) is a schematic diagram showing distance data acquired by the sensor 23 of the handrail 5 provided on the side wall 11b, FIG. 20(d) is a schematic diagram showing occupied area data corresponding to FIG. 20(c), and FIG. 20(e) is occupied area data obtained by integrating the two occupied area data.

[0099] As shown in FIG. 19, there are two people 40A and 40B inside the car 1. In this situation, the sensor 23 on the handrail 5 provided on the side wall 11a acquires the distance data shown in FIG. 20(a). As shown in FIG. 20(a), the measured distance is shorter where the people 40A and 40B are present. Occupied area data is generated based on this measurement result. As shown in FIG. 20(b), the occupied area data includes occupied area 41AB-1 and occupied area 41Z-1. Occupied area 41AB-1 corresponds to the people 40A and 40B, and occupied area 41Z-1 corresponds to the handrail 5 provided on the side wall 11b. The sensor 23 on the handrail 5 provided on the side wall 11a acquires the distance data shown in FIG. 20(c). As shown in FIG. 20(c), the measured distance is shorter where the people 40A and 40B are present. Occupied area data is generated based on this measurement result. 20(d), the occupied area data includes occupied area 41AB-2 and occupied area 41Z-2. Occupied area 41AB-2 corresponds to person 40A and person 40B, and occupied area 41Z-2 corresponds to handrail 5 provided on side wall 11a.

[0100] In the sixth embodiment, two pieces of occupied area data are integrated to generate one piece of occupied area data. As shown in FIG. 20(e), the integrated occupied area data includes an occupied area 41AB. The handrails 5 provided on the side walls 11a and 11b have a weak correlation with the person in the car 1 to be detected. For this reason, the occupied areas 41Z-1 and 41Z-2 corresponding to the two handrails 5 are processed to be excluded.

[0101] The integrated occupied area data will be described using examples. Figure 21 is a first example illustrating the integrated occupied area data in the sixth embodiment, where Figure 21(a) is a schematic diagram of the car 6 viewed from above (upper side in the Z direction in Figure 18), and Figure 21(b) is the integrated occupied area data. Figure 22 is a second example illustrating the integrated occupied area data in the sixth embodiment, where Figure 22(a) is a schematic diagram of the car 6 viewed from above (upper side in the Z direction in Figure 18), and Figure 22(b) is the integrated occupied area data. Figure 23 is a third example illustrating the integrated occupied area data in the sixth embodiment, where Figure 23(a) is a schematic diagram of the car 6 viewed from above (upper side in the Z direction in Figure 18), and Figure 23(b) is the integrated occupied area data.

[0102] In the first example, as shown in Fig. 21(a), people 40A and 40B are close to each other on the far right side of car 1 (the right side in the X direction, the far side in the Y direction in Fig. 18). In this situation, as shown in Fig. 21(b), the occupied area data includes occupied area 41AB. Occupied area 41AB corresponds to people 40A and 40B.

[0103] In the second example, as shown in FIG. 22(a), person 40A is present on the far left side of car 1 (left side in the X direction, far side in the Y direction in FIG. 18), and person 40B is present on the near left side of car 1 (left side in the X direction, near side in the Y direction in FIG. 18). Persons 40A and 40B are present at positions separated from each other. In this situation, as shown in FIG. 22(b), the occupied area data includes occupied area 41A and occupied area 41B. Occupied area 41A corresponds to person 40A, and occupied area 41B corresponds to person 40B.

[0104] In the third example, as shown in FIG. 23(a), person 40A is present on the far right side of car 1 (the right side in the X direction, the far side in the Y direction in FIG. 18), and person 40B is present on the near left side of car 1 (the left side in the X direction, the near side in the Y direction in FIG. 18). Persons 40A and 40B are present at positions separated from each other. In this situation, as shown in FIG. 22(b), the occupied area data includes occupied area 41A and occupied area 41B. Occupied area 41A corresponds to person 40A, and occupied area 41B corresponds to person 40B.

[0105] In this way, when one piece of occupied area data generated based on distance data acquired by two sensors 23 arranged opposite to each other is used, the accuracy of detecting a person in the car 1 is improved compared to when occupied area data generated based on distance data acquired by one sensor is used. This improves the accuracy with which the abnormality determination unit 25 determines that an abnormality has occurred, making it possible to issue an alarm in a more accurate situation.

[0106] In the sixth embodiment, each of the two handrails 5 may perform an alarm operation, or only one of them may perform an alarm operation. The configuration for transmitting and receiving data between the two handrails 5 is not particularly limited. The data transmitted and received may be distance data. Furthermore, at least one of the two handrails 5 may be configured to transmit distance data or occupied area data to the other handrail 5.

[0107] Embodiment 7 The configuration of an elevator car 81 in embodiment 7 will be described. Figure 24 is a schematic diagram of the inside of an elevator car 81 in embodiment 7 as seen from the entrance / exit side. Embodiment 7 differs from embodiment 1 in that elevator car 81 is provided with handrails 5 on each of two side walls 11a and 11b and the front wall 13. The same components as in embodiment 1 are given the same reference numerals, and their description will be omitted.

[0108] The elevator car 81 is equipped with three handrails 5. The three handrails 5 are provided on the side wall 11a, the side wall 11b, and the front wall 12, respectively. Two of the three handrails 5 are arranged so that their longitudinal direction is along the width direction of the side wall 11a and the side wall 11b, respectively. The two handrails 5 provided on each of the side walls 11a and 11b are arranged facing each other. One of the three handrails 5 is arranged so that its longitudinal direction is along the width direction of the front wall 12 (the X direction in FIG. 24).

[0109] In the seventh embodiment, a person in the car 1 is detected by two sensors 23 arranged opposite to each other and one sensor 23 arranged at a position perpendicular to these two sensors 23. Three pieces of occupied area data generated based on the distance data acquired by these three sensors 23 are integrated to generate one piece of occupied area data, and a person in the car 1 is detected using the integrated occupied area data. Therefore, the accuracy of detecting a person in the car 1 is improved compared to when occupied area data generated based on distance data acquired by one or two sensors is used. This improves the accuracy with which the abnormality determination unit 25 determines that an abnormality has occurred, making it possible to issue an alarm in a more accurate situation.

[0110] In the seventh embodiment, each of the three handrails 5 may perform an alarm action, or only one of them may perform an alarm action.

[0111] In the seventh embodiment, a configuration has been described in which three handrails 5 are provided on each of the side wall 11a, the side wall 11b, and the front wall 12, but the configuration for attaching the handrails 5 is not limited to this, and a total of two handrails 5 may be provided on one of the side walls 11a and 11b and the front wall. The locations where the handrails 5 are attached can be set appropriately depending on the structure inside the car 1, etc.

[0112] It should be noted that appropriate combinations, modifications, and omissions of the respective embodiments are also included within the scope of the technical ideas shown in the embodiments.
