[0009] Embodiment 1 The configuration of an elevator car 1 (hereinafter, simply referred to as "car 1") in the first embodiment will be described. Fig. 1 is a perspective view showing an outline of the car 1 in the first embodiment. Fig. 2 is a schematic diagram of the inside of the car 1 in the first embodiment as viewed 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 chamber 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. The car ceiling 3 is provided with a lighting fixture 3a. 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 wall 11a and the side wall 11b face each other. The front wall 12 and the 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 aligned with the width direction of the side wall 11a (Y direction in FIG. 1).
[0014] We will now explain the detailed configuration of the handrail 5. Fig. 3 is a schematic diagram showing the appearance of the handrail 5 in embodiment 1, in which Fig. 3(a) is a diagram of the handrail 5 seen from above (the upper side in the Z direction in Fig. 2), Fig. 3(b) is a diagram of the handrail 5 seen from the front (the right side in the X direction in Fig. 2), and Fig. 3(c) is a diagram of the handrail 5 seen from the side (the 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 the handrail 5 is fixed to the side wall 11a by this attachment portion 21a. The length of the handrail main body 21 in the longitudinal direction (the left-right direction in FIG. 3(b)) can be appropriately adjusted 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 configuration of the security device 22 is arranged so as to be visible from the exterior of the handrail body 21. Specifically, the sensor 23 and the light-emitting device 31 that constitute the security device 22 are arranged along the longitudinal direction of the handrail body 21. The sensor 23 and the light-emitting device 31 are provided on the handrail body 21 so as to be arranged facing the inside of the car 1 when the handrail 5 is fixed to the side wall 11a. The speaker 32 that constitutes the security device 22 is arranged on the side of the handrail body 21.
[0017] In the handrail 5, the sensor 23 is arranged along the longitudinal direction of the handrail main body 21, so blind spots are unlikely to form and the crime prevention function is unlikely to be hindered. For example, if a security camera is installed in the car 1 as a crime prevention function, blind spots are likely to form. Furthermore, the crime prevention function of the security camera is likely to be hindered if the lens is covered. In contrast, in the handrail 5, the sensor 23 is arranged along the longitudinal direction of the handrail main body 21 and is installed along the width direction of the side wall 11a. In this way, since the sensor 23 is arranged over a wide range, blind spots are unlikely to form and the crime prevention function is unlikely to be hindered compared to the case where 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 a crime in which a person harms another person in 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 in 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. The threshold is a distance at which a person is expected to harm another person, and is, for example, 0.5 to 0.75 m. The threshold can be set appropriately depending on the installation status and operation 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" refers to 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 are about to cause harm, by alerting people who are about to be harmed, or by reporting the situation 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 in the car 1. The light-emitting device 31 emits light in red, for example. The speaker 32 emits sound to alert or warn people in 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 notifies people outside the car 1 of an abnormality in the car 1 by communicating with devices outside 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 landing. The communication device 33 requests rescue by reporting to the security company. In addition, the communication device 33 notifies a terminal installed at the elevator landing to notify the surroundings (for example, people waiting at the landing) that an abnormality has occurred in the car 1, and encourages a quick response. 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 the 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 the 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 operation program stored in the secondary storage device 105 into the memory 103 and executes the operation program, thereby implementing each function of the security device 22.
[0025] The memory 103 is a main storage device constituted by, for example, a RAM (Random Access Memory). The memory 103 stores a program read by the processor 102 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. Through the interface 104, communication with other devices is performed.
[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. 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 the first embodiment, Fig. 6(a) is a schematic diagram of the car room 6 as viewed 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 monitors the situation inside the car 1 by dividing the car room 6 into a grid pattern. The size of one division is, for example, 1 cm. 2 Note that FIG. 6(b) is a schematic diagram, and the number of lattices does not necessarily indicate the number of actual lattices.
[0030] Next, a configuration for detecting a person in the car 1 in the first embodiment will be described. An example will be described in which there are two people in the car 1, person 40A and person 40B. Fig. 7 is an explanatory diagram for explaining the configuration for detecting a person in the car 1 in the first embodiment, Fig. 7(a) is a schematic diagram of the car room 6 viewed 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 in 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 the people 40A and 40B are present. Based on this distance data, the distance calculation unit 24 generates occupancy area data. As shown in FIG. 7(c), the occupancy area data includes occupancy area 41A and occupancy area 41B. The occupancy area 41A corresponds to the person 40A, and the occupancy area 41B corresponds to the person 40B. The occupancy area data makes it possible to know the presence or absence of people, the positions of the people in the car 1, the distance between the 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 flow chart 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. The abnormality determination unit 25 determines whether the distance transmitted from 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 S12), the process proceeds to step S13, and if it is determined to be not equal to or less than the threshold (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 an instruction to start up 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 has been described in which the distance calculation unit 24 calculates the distance between people at a certain time and transmits it to the abnormality determination unit 25, the configuration is not limited thereto, and the distance calculation unit 24 may be configured to calculate the ratio before and after the change in the distance between people and transmit it to the abnormality determination unit 25. When using the ratio before and after the change in the distance between people, the abnormality determination unit 25 compares the ratio before and after the change in the distance transmitted from the distance calculation unit 24 with a threshold value. For example, if the distance between people is 1 m at a certain time and 0.4 m several seconds later, the ratio 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 in order to secure personal space. When people get closer to each other than the normally expected distance in the car 1, there is a risk that they may attempt to harm others. Therefore, the security device 22 in the first embodiment prevents security 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 the second embodiment will be described. Fig. 9 is a block diagram showing the functions of the security device 42 in the second embodiment. The second embodiment differs from the first embodiment in that the security device 42 further includes an individual group identification unit 46. The same components as those in the first embodiment are given the same reference numerals, and the description thereof 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 person in car 1 is an individual user or a group user. 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." Or, if there are three people in car 1, "person A" and "duo C" who is a different person from "person A," "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 similar to the hardware configuration of the control functions of the security device 22 in embodiment 1.
[0044] A configuration for detecting a person in the cage 1 in the embodiment 2 will be described. An example will be described in which there are three people in the cage 1, namely, a person 40A, a person 40B, and a person 40C, and the person 40A is an individual user, and the people 40B and 40C are a pair of users who are different from the person 40A.
[0045] Figure 10 is an explanatory diagram explaining the configuration for detecting people inside the cage 1 in embodiment 2, where Figure 10(a) is a schematic diagram of the cage 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 cage 1. People 40B and 40C have a known human relationship. Therefore, people 40B and 40C are located close to each other. Person 40A is a stranger who has an unknown human relationship with people 40B and 40C. Therefore, person 40A is located farther away from people 40B and 40C than the distance between person 40B and person 40C.
[0047] In this situation, the sensor 23 obtains distance data shown in FIG. 10(b). As shown in FIG. 10(b), the measured distance is shorter in the locations where the person 40A, the person 40B, and the person 40C are present. Based on this distance data, the occupancy area data is generated. As shown in FIG. 10(c), the occupancy area data includes an occupancy area 41A and an occupancy area 41BC. The occupancy area 41A corresponds to the person 40A, and the occupancy area 41BC corresponds to the duo of the person 40B and the person 40C. The occupancy areas of people who are closer than a predetermined distance from the beginning are grouped together. The occupancy area 41BC is larger than the occupancy area 41A. The occupancy area data makes it possible to determine whether there is a person, the position of the person in 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 the embodiment 2. Fig. 11 is a flow chart showing the alarm operation by the security device 42 in the embodiment 2.
[0049] In step S21, it is identified whether the person in the car 1 is an "individual user" or a "group user". The sensor 23 acquires distance data. The distance calculation unit 24 generates occupancy 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 occupancy area data. The individual / group identification unit 46 identifies the person as an "individual user" when the occupancy area is smaller than a predetermined area, and identifies the person as a "group user" when the occupancy 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 analyzing in advance the area of an occupancy area that can correspond to one person.
[0050] In step S22, it is determined whether or not the people in cage 1 include a "group user." The abnormality determination unit 25 determines whether or not the people in cage 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 cage 1 (No in step S22), the process proceeds to step S23, and if a "group user" is included in cage 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 to be not 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 an instruction to start up 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 management 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 car 1 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 car 1 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 (such as friends or parents and children). Also, 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 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 appropriately set 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 further 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 similar to 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 the third embodiment. Fig. 13 is a flow chart showing the alarm operation by the security device 52 in the third embodiment.
[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 number of people 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. 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 that it is equal to or less than the threshold (Yes in step S34), the process proceeds to step S35, and if it is determined that it is not equal to or less than the threshold (No in step S34), the process proceeds to step S33.
[0067] In step S35, an alarm is issued. The alarm control unit 34 transmits an instruction to start up 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 management 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 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 may be set appropriately depending on the installation and operating conditions of the elevator.
[0069] In the third embodiment, the car 1 is configured to issue an alarm in a predetermined case in a situation where the number of people in the car 1 is within a predetermined range. In other words, the car 1 is configured not to issue an alarm when 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 considered that crimes are less likely to occur because the eyes of others act as a deterrent. In addition, when there are many people in the car 1, the distance between people becomes close, which may lead to a false alarm. Specifically, when there are many people in the car 1, there is a possibility that a movement of approaching other people without the intention of committing a crime occurs. In this case, the alarm device 30 issues an alarm, which is different from the original intention and is a false alarm. On the other hand, when the number of people in the car 1 is one or less, no action that harms other people can occur. For this reason, 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 crime prevention function.
[0070] Embodiment 4 The configuration of the security device 62 in the fourth embodiment will be described. Fig. 14 is a block diagram showing the functions of the security device 62 in the fourth embodiment. The fourth embodiment differs from the first embodiment in that the security device 62 further includes a speed detector 48. The same components as those in the first embodiment are given the same reference numerals, and the description thereof 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 moving speed of the car 1. The speed detector 48 is, for example, a speed sensor or an acceleration sensor.
[0072] In embodiment 4, abnormality judgment unit 25 judges that an abnormality has occurred when the speed detected by speed detector 48 is equal to or greater than a predetermined speed and the distance calculated by 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 the fourth embodiment. Fig. 15 is a flow chart showing the alarm operation by the security device 62 in the fourth embodiment.
[0074] In step S41, the speed of the car 1 is measured. The speed detector 48 measures the moving speed of the car 1. 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 appropriately set based on the normal operating speed of car 1, etc. For example, 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 that it is equal to or less than the threshold (Yes in step S44), the process proceeds to step S45, and if it is determined that it is not 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 an instruction to start up 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 management 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 alarm is set to be issued in a predetermined case in a situation where the speed at which the car 1 moves is equal to or higher than a predetermined speed. In other words, the alarm is not set to be issued when the speed at which the car 1 moves is lower than the predetermined speed. The speed at which the car 1 moves is slow when the car 1 is stopped or before and after the car stops. When the car 1 is stopped or before and after the car stops, people in the car 1 move to get on and off the car. As a result, movements that approach other people without criminal intent may occur in the car 1. In this case, the alarm device 30 issues an alarm, which is different from the original intention and is a malfunction. For this reason, by setting the alarm not to be issued when the speed at which the car 1 moves is lower than a predetermined speed, an alarm can be issued in a more accurate situation without reducing the crime prevention function.
[0082] Embodiment 5. The configuration of security device 72 in embodiment 5 will be described. Fig. 16 is a block diagram showing the functions of security device 72 in embodiment 5. Embodiment 5 differs from embodiment 1 in that security device 72 further includes 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 cage 1 is a registrant. The registrant determination unit 49 determines whether the person in the cage 1 is a registrant based on the registrant information stored in a communication device (e.g., a mobile phone or an electronic tag) carried by the person in the cage 1 in a bag or pocket, and transmits the determination result to the abnormality determination unit 25. For example, it is assumed that related parties (e.g., residents) of an apartment building usually use the elevator installed in the apartment building. Related parties record the registrant information in advance using a communication device as a medium in accordance with the management rules of the apartment building. On the other hand, non-related parties do not carry a medium on which the registrant information is recorded. When the specified registrant information is acquired, the user is a registrant, and when the specified registration information is not acquired, the user is not a registrant. This distinguishes whether the person in the cage 1 is a normally expected user or an external user who is not normally expected.
[0085] In embodiment 5, the abnormality judgment unit 25 judges that an abnormality has occurred when the judgment result of the registrant judgment 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 similar to the hardware configuration of the control functions of the security device 22 in embodiment 1.
[0087] A configuration for detecting a person in the cage 1 in the fifth embodiment will be described. An example will be described in which there are three people in the cage 1, a person 40A, a person 40B, and a person 40C, and the person 40A is an individual user, and the people 40B and 40C are a pair of users who are different from the person 40A.
[0088] A description will now be given of the alarm operation by the security device 72 in the fifth embodiment. Fig. 17 is a flow chart showing the alarm operation by the security device 72 in the fifth embodiment.
[0089] In step S51, it is determined whether or not the person in the cage 1 is a registered person. The registered person determination unit 49 attempts to acquire registered person information from a communication device owned by the person in the cage 1. The registered person determination unit 49 determines whether or not each person in the cage 1 is a registered person based on the acquired result. 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 non-registered user in the cage 1. The abnormality determination unit 25 determines whether or not there is a non-registered user in the cage 1 based on the determination result transmitted from the registrant determination unit 49. If there is a non-registered user in the cage 1 (Yes in step S52), the process proceeds to step S53, and if there is no non-registered user in the cage 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. 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 S54), the process proceeds to step S55, and if it is determined to be not equal to or less than the threshold (No in step S54), the process proceeds to step S53.
[0093] In step S55, an alarm is issued. The alarm control unit 34 transmits an instruction to start up 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 management 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 elevator is configured to issue an alarm in a predetermined case in a situation where there is a user who is not a registered user in the elevator 1. In other words, the elevator is configured not to issue an alarm if all the people in the elevator 1 are registered users. It is considered that users who regularly use the elevator (for example, residents of the apartment building where the elevator is located, workers who work in the building where the elevator is located, etc.) are less likely to commit crimes. It is considered that crimes are less likely to occur when only regular users are in the elevator 1 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 elevator 1 are registered users, it is possible to issue an alarm in a more accurate situation without reducing the crime prevention function.
[0096] Embodiment 6 The configuration of elevator car 71 in embodiment 6 will be described. Fig. 18 is a schematic diagram of the inside of elevator car 71 in embodiment 6 as viewed 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 walls 11a and 11b, respectively. The two handrails 5 are arranged such that the longitudinal direction is aligned with the width direction of the side walls 11a and 11b, respectively. The two handrails 5 are arranged to face each other. The two handrails 5 transmit and receive occupation area data to and from each other.
[0098] A configuration for detecting a person in the car 1 in the sixth embodiment will be described. An example will be described in which there are two people in the car 1, a person 40A and a person 40B. 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 a 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 a person 40A and a person 40B in the car 1. In this situation, the sensor 23 of the handrail 5 provided on the side wall 11a acquires distance data shown in FIG. 20(a). As shown in FIG. 20(a), the measured distance is shorter at the location where the person 40A and the person 40B are present. Based on this measurement result, the occupied area data is generated. As shown in FIG. 20(b), the occupied area data includes an occupied area 41AB-1 and an occupied area 41Z-1. The occupied area 41AB-1 corresponds to the person 40A and the person 40B, and the occupied area 41Z-1 corresponds to the handrail 5 provided on the side wall 11b. The sensor 23 of the handrail 5 provided on the side wall 11a acquires distance data shown in FIG. 20(c). As shown in FIG. 20(c), the measured distance is shorter at the location where the person 40A and the person 40B are present. Based on this measurement result, the occupied area data is generated. 20(d), the occupied area data includes an occupied area 41AB-2 and an occupied area 41Z-2. The occupied area 41AB-2 corresponds to the person 40A and the person 40B, and the occupied area 41Z-2 corresponds to the handrail 5 provided on the 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. Fig. 21 is a first example for explaining the integrated occupied area data in the sixth embodiment, in which Fig. 21(a) is a schematic diagram of the car 6 viewed from above (upper side in the Z direction in Fig. 18), and Fig. 21(b) is the integrated occupied area data. Fig. 22 is a second example for explaining the integrated occupied area data in the sixth embodiment, in which Fig. 22(a) is a schematic diagram of the car 6 viewed from above (upper side in the Z direction in Fig. 18), and Fig. 22(b) is the integrated occupied area data. Fig. 23 is a third example for explaining the integrated occupied area data in the sixth embodiment, in which Fig. 23(a) is a schematic diagram of the car 6 viewed from above (upper side in the Z direction in Fig. 18), and Fig. 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 the 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 an occupied area 41AB. The occupied area 41AB corresponds to the people 40A and 40B.
[0103] In the second example, as shown in FIG. 22(a), a person 40A is present at the rear left side of the car 1 (left side in the X direction, rear side in the Y direction in FIG. 18), and a person 40B is present at the front left side of the car 1 (left side in the X direction, front side in the Y direction in FIG. 18). The people 40A and 40B are present at positions separated from each other. In this situation, as shown in FIG. 22(b), the occupation area data includes an occupation area 41A and an occupation area 41B. The occupation area 41A corresponds to the person 40A, and the occupation area 41B corresponds to the person 40B.
[0104] In the third example, as shown in FIG. 23(a), a person 40A is present at the far right side of the car 1 (the right side in the X direction, the far side in the Y direction in FIG. 18), and a person 40B is present at the near left side of the car 1 (the left side in the X direction, the near side in the Y direction in FIG. 18). The people 40A and 40B are present at positions separated from each other. In this situation, as shown in FIG. 22(b), the occupation area data includes an occupation area 41A and an occupation area 41B. The occupation area 41A corresponds to the person 40A, and the occupation area 41B corresponds to the 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 the case where 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. Also, 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 elevator car 81 in embodiment 7 will be described. Fig. 24 is a schematic diagram of the inside of elevator car 81 in embodiment 7 as viewed 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 has three handrails 5. The three handrails 5 are provided on the side wall 11a, the side wall 11b, and the front wall 12. 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. The two handrails 5 provided on the side wall 11a and the side wall 11b are arranged to face 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 the two sensors 23. Three pieces of occupation area data generated based on the distance data acquired by the three sensors 23 are integrated to generate one piece of occupation area data, and a person in the car 1 is detected using the integrated occupation area data. This improves the accuracy of detecting a person in the car 1 compared to the case where occupation 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, and makes 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 in which three handrails 5 are provided on each of the side wall 11a, the side wall 11b, and the front wall 12 has been described, but the configuration for attaching the handrails 5 is not limited to this, and a total of two handrails 5 may be provided on either one of the side wall 11a and the side wall 11b and the front wall. The locations at which the handrails 5 are attached can be appropriately set depending on the structure inside the car 1, etc.
[0112] In addition, appropriate combinations, modifications, and omissions of the respective embodiments are also included within the scope of the technical ideas presented in the embodiments.
[0113] According to the elevator car handrail of the present disclosure, a security function can be installed inside the elevator car in addition to the handrail function through the same normal work as installing a handrail inside the elevator car.
