TECHNICAL FIELD OF THE INVENTION
The present invention relates to a passenger detection device in an elevator car for detecting a passenger such as a disabled person staying in the elevator car.
[0002]
[Prior art]
In hospitals, nursing homes, etc., people other than healthy people may also use the elevator, but if you can not move because of unconsciousness in the elevator or if you can not operate the car while staying in the car due to dementia, Passengers in the car are in a very dangerous state, and a third party such as a nurse or caregiver cannot easily detect the dangerous state.
[0003]
In the past, while transmitting a transmitter to a specific person who needs nursing care, a receiver was installed on the car side to receive a signal transmitted from the transmitter when the specific person approached the landing door. The car door is blocked by opening the car door by stopping the door opening / closing motor, thereby creating a state in which a specific person cannot enter the car.
[0004]

[0005]
[Problems to be solved by the invention]
However, in the above-described conventional techniques, it is necessary to change the transmitter every time a specific person changes clothes, which is very complicated. In addition, if a person who forgets to put on the transmitter or has a high need for nursing care but has not yet put on the transmitter cannot move due to unconsciousness in the elevator, the car cannot be operated while remaining in the car due to dementia. In this case, if the person falls further in the car and cannot get up, only one person is left in the car, and the situation in the car cannot be detected at all.
[0006]
The present invention has been made in view of the above circumstances, and in a case where a passenger stays in an elevator car and cannot operate the car, for example, a nurse, a caregiver, etc. can quickly detect the elevator car. An object is to provide a passenger detection device.
[0007]
[Means for Solving the Problems]
(1) In order to solve the above problems, the passenger detection device in the elevator car according to the present invention is configured by arranging a plurality of passenger detection sensors at predetermined intervals on the opposing baseboards or side plates in the car. In addition, since a plurality of passenger detection sensors can provide an output different from the state where the passenger is standing when the passenger falls in the car, it is possible to detect the passenger falling in the car.
[0008]
(2) Further, the passenger detection device in the elevator car according to the present invention includes a plurality of passenger detection sensors arranged at predetermined intervals on a baseboard or a lower portion of a side plate facing each other in the car, and the plurality of passenger detection sensors. A control processing unit for detecting a dangerous state of the passenger in the car from the output of the sensor and the output of one or both of the destination floor operation button and the call button in the car, and being installed at a predetermined monitoring place, This is a configuration provided with a car monitoring panel for notifying a dangerous state signal sent from the control processing unit.
[0009]
According to the present invention having the above-described configuration, not only can the passenger's falling state be determined from the outputs of the plurality of passenger detection sensors, but also one or both of the destination floor operation button and the call button in the car can be determined. If the operation is not performed for a long time, it is determined that the person is in a dangerous state by himself, and the dangerous state signal is notified from the car monitoring panel, thereby enabling quick rescue.
[0010]
(3) If a load detector is installed below the car floor in addition to the outputs of the plurality of passenger detection sensors, it is detected from the output of the load detector that the passenger in the car is alone. Thus, it is possible to detect the state of suspected danger with higher accuracy.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0012]
(First Embodiment)
FIG. 1 is a configuration diagram of a car including an electric system showing an embodiment of a passenger detection device in an elevator car according to the present invention. FIG. 1A is a view of the car door side from inside the car, and FIG. 1B is a side view of the car.
[0013]
The electric system configuration of the elevator is installed in a car control panel (not shown) installed above the car 1 as shown in FIG. 1 (a), a nurse center in a hospital, a staff room in a nursing home, and the like. The elevator monitoring panel 2 is connected via a signal line 3 and an elevator control panel 4.
[0014]
The car 1 has a car floor 11, a side plate 12, a top plate 13, a front door 14, and a curtain arranged between the upper portion of the front door 14 and the top plate 13 as shown in FIGS. It is composed of a board 15, a baseboard 16 attached between the car floor 11 and the side plate 12, and the like. 17 is a car operation panel.
[0015]
Further, as shown in FIG. 2A, the car 1 has passenger detection sensors 18,... At a required height position of the opposing baseboards 16 constituting the car 1 or at a predetermined interval below the side plate 12. Is installed. In this passenger detection sensor 18, light-emitting elements 18a,... Are arranged at predetermined intervals below one of the baseboards 16 or the side plates 12, and are similarly arranged at predetermined intervals on the other facing baseboard 16 or the side plates 12. The light receiving elements 18b are arranged. The predetermined interval is, for example, about 1.3 to 1.8 times the length of a person having a relatively large length of foot, or is an average, in order to distinguish it from a passenger standing on the car floor. The interval is set to, for example, about 2 to 2.5 times the length of the foot of a person having a long foot.
[0016]
The elevator monitoring panel 2 determines the state of suspected danger from the output of the passenger detection sensor 21 and, despite the fact that the passenger has boarded the car 1, controls the car operation panel including the destination floor operation button of the car operation panel. When the state in which the call button provided cannot be pressed continues, a danger state signal is transmitted to the elevator monitoring panel 2, and a notification means such as a buzzer 21a and a lamp 21b for notifying the danger state from the elevator monitoring panel 2 and a call button are provided. An intercom 22 that responds when pressed is provided. The state in which the call button including the destination floor operation button cannot be pressed is a state in which the person who got into the elevator car 1 has become unconscious, a state in which the person has fallen into the car 1 due to poor physical condition, or A state in which a person with dementia cannot operate the car while riding the car.
[0017]
Further, one of the car control panel, the elevator control panel 4 and the elevator monitoring panel 2 is provided with a control processing unit 30 composed of a CPU that determines a dangerous state based on the outputs of the plurality of passenger detection sensors 18. ing. Considering that a location where various signals such as a car call signal and a registration signal of a destination floor can be collected is effective, it is desirable to provide the control processing unit 30 in the elevator control panel 4.
[0018]
As shown in FIG. 3, the control processing unit 30 determines whether or not the passenger has got on the car 1 by the car riding determining means 31 which determines that the passenger has got on the car 1. Danger suspicion determining means 32 for determining whether or not there is a danger suspicion state based on the outputs of the plurality of passenger detection sensors 18. If the determination means 32 determines that the danger suspicion exists, the destination floor operation is performed for a predetermined time. When the call button including the button is not pressed, the danger state determination means 33 for determining the danger state is established, and when the danger state is determined, the danger state signal is sent to the elevator monitoring panel 2 and the buzzer 21a, For example, a danger state signal sending unit 34 for operating a notifying unit such as the red lamp 22b is provided.
[0019]
Next, the operation of the passenger detection device as described above will be described with reference to FIG.
[0020]
After the start of the operation of the elevator, the control processing unit 30 executes the car riding determination unit 31. When there is a car call from the landing operation panel (S1), the car riding determination means 31 confirms the arrival at the landing floor (S2), and then confirms that the car door is open and the car door is closed (S3, S4). It is determined that the passenger has got into the car 1.
[0021]
Thereafter, the control processing unit 30 executes the danger suspicion determination unit 32. The danger suspicion determining means 32 determines whether or not there is a danger suspicion from the output of the passenger detection sensor 18 arranged on the baseboard 16 or the side plate 12 of the car 1 and from the output of the passenger detection sensor 18. Even when the call is made, if the call button including the destination floor operation button is not pressed in one direction, it may be determined that the danger is suspected.
[0022]
The former example of judging the danger from the output of the passenger detection sensor 18 is based on the fact that, when the passenger is standing in the car 1 in a normal state, at most two adjacent lights out of the plurality of light emitting elements 18a are output. The light emitted from the light projecting element 18a, or the light emitted from the light projecting elements 18a on both sides of the light receiving element 18b that receives the light from the light projecting element 18a, For example, when four or more adjacent light receiving elements 18b do not receive light, it is considered that the passenger 19 has fallen for some reason as shown in FIG. When the light from the light emitting element 18a is randomly blocked, it can be determined that a plurality of passengers are on board. On the other hand, in the latter case where the call button including the destination floor operation button is not pressed at all, the call button including the destination floor operation button may not be able to be pressed when an unconscious person or a person with dementia is standing. In danger of doubt.
[0023]
Therefore, the danger suspicion determining means 32 sets the time memory to the initial state t = 0, t 'after the car door is closed (S5, S6), and outputs the passenger detection sensor 18, that is, a large number of light receiving elements 18b,. (S7), and it is determined whether or not the passenger has fallen and is in a state of suspected danger (S8). Further, when it is determined from the output of the passenger detection sensor 18 that the vehicle is not in a state of suspected danger, and when the call button including the destination floor operation button is not pressed, it is determined that the passenger is in a state of suspected danger (S9). , S10).
[0024]
Therefore, if it is determined in step S8 or S9, S10 that the vehicle is in a state of doubt of danger, the danger state determination unit 33 is executed.
[0025]
The danger state determination means 33 determines whether or not the destination floor operation button has been pressed when it is determined in step S8 that the danger is suspected (S11), and when the destination floor operation button has been pressed. It is determined that there is no danger suspected state, and if the destination floor operation button has not been pressed, it is determined whether the call button has been pressed (S12), and the destination floor operation button has been pressed. In this case, a notification signal is transmitted (S13). Since the interphone 22 of the elevator monitoring panel 2 sounds according to this notification signal, a nurse or a caregiver can take measures such as rescue. If the call button has not been pressed, it is determined whether or not a predetermined time T has elapsed (S14). If not, the unit time Δt is incremented (S15), and the same processing is repeated. If the predetermined time T has elapsed in step S14, it is determined that the vehicle is in a dangerous state from the suspected danger, a dangerous state signal is transmitted (S16), and the buzzer 21a provided in the elevator monitoring panel 2 sounds.
[0026]
On the other hand, even if it is determined in step S8 that there is no doubt about danger, there is a case where the person is standing in the car by an unconscious person or a person with dementia as described above. It is determined whether or not the call button including the floor operation button has been pressed. If none of the buttons has been pressed, it is determined whether or not a predetermined time T 'has elapsed (S17). If not, Δt is incremented (S18), and the same processing is repeated. If the predetermined time T 'has elapsed, the danger state is similarly determined from the danger doubt, and a danger state signal is transmitted (S16), and the buzzer 21a and the like of the elevator monitor 2 are sounded.
[0027]
The relationship between the predetermined time T and T 'is T = T' or T? Let T '. This is because if it is determined in step S8 that the danger is suspected, the vehicle is in a collapsed state and the degree of urgency is high.
[0028]
Therefore, according to the above-described embodiment, the light emitting and receiving elements 18a,..., 18b,... Are arranged at predetermined intervals at predetermined height positions of the baseboard 16 facing each other or below the side plate 12. By providing a plurality of passenger detection sensors 18, it is possible to detect the state of a person who has fallen in the car 1 based on the output of the passenger detection sensors 18.
[0029]
Also, considering the output of the passenger detection sensor 18 and the state in which the call button including the destination floor operation button is not pressed, the suspicion of a person who has fallen in the car 1 becomes clear, and an unconscious person or dementia If the person is standing in the car but cannot operate the destination floor operation button and call button, it can be determined that the vehicle is in a dangerous state.
[0030]
(Second embodiment)
FIG. 5 is a configuration diagram including an electric system showing another embodiment of the passenger detection device in the elevator car according to the present invention. In this figure, the same parts as those in FIGS. 1 and 2 are denoted by the same reference numerals, and the detailed description is left to the description of FIGS.
[0031]
In this passenger detection device, a particularly different point is that a load detector 40 is installed in the lower part of the car floor of the car, and the control processing unit 30 determines the output of the passenger detection sensor 16 and the load detected by the load detector 40. Is used to determine a suspected danger state.
[0032]
As the handling of the load measured by the load detector 40, for example, the lower limit is a predetermined elevator car weight, and the upper limit is a value obtained by adding the weight equivalent to the average weight of two passengers to the lower limit. When the load detector 40 detects a load in a required range between the lower limit and the upper limit, it is determined that one passenger is in the car.
[0033]
Accordingly, as shown in FIG. 7, the control processing unit 30 includes a car riding determination unit 31, a danger suspicion determination unit 32, a danger state determination unit 33, and a danger state signal transmission unit 34. The judging means 32 includes a falling state judging means 32a for judging a falling state from the output of the passenger detecting sensor 18 and a passenger number judging means 32b for judging that one passenger is on the basis of the load detected by the load detector 40. It is constituted by.
[0034]
In the operation process of the control processing unit 30, when it is determined in step S8 of FIG. 4 that the passenger is falling down, the passenger number determining unit 32b determines whether the number of passengers is one or not, and If there is, a danger doubt is finally determined, and the process proceeds to step S11.
[0035]
Therefore, according to the above-described embodiment, in addition to the same effects as those of the above-described first embodiment, not only is it possible to determine the state of falling in the car, but also to ride on the car. Since the number of passengers can also be determined, it is possible to determine the risk doubt with higher accuracy.
[0036]
(Other embodiments)
(1) In the above embodiment, the passenger detection sensors 18,... Use optical projection / reception elements 18a,..., 18b,. Good.
[0037]
(2) Further, a light emitting and receiving means is provided below one of the baseboards 16 and the side plate 12, and reflectors are arranged at predetermined intervals on the lower side of the other baseboard 16 and the side plate 12 facing these light emitting and receiving means. Alternatively, a configuration in which one long reflector is attached may be used.
[0038]
(3) Further, in addition to arranging the light emitting / receiving elements 18a,..., 18b,... At predetermined intervals below the baseboard 16 and the side plate 12 facing each other, the lower part of the car operation panel as shown in FIG. A passenger detection sensor 18 'may be additionally mounted on the baseboard 16 and the lower portion of the side plate 12 corresponding to the above. This is because, in particular, when only one passenger is on the car 1, usually, the car often stands near the car equipment panel or falls over in the vicinity. In addition, the installation density of the passenger detection sensor can be changed over the depth direction of the car. In addition, it is possible to improve the detection accuracy by installing passenger detection sensors in each of the width direction and the depth direction of the car.
[0039]
In addition, the present invention is not limited to the above-described embodiment, and can be variously modified and implemented without departing from the gist thereof.
[0040]
Further, the embodiments can be implemented in combination as much as possible, and in that case, the effect of the combination can be obtained. Furthermore, each of the above embodiments includes various upper and lower stage inventions, and various inventions can be extracted by appropriately combining a plurality of disclosed components. For example, when an invention is extracted because some constituent elements can be omitted from all the constituent elements described in the means for solving the problem, if the extracted invention is implemented, the omitted part is omitted. Is appropriately supplemented by well-known conventional techniques.
[0041]
