[0067] Detailed description

[0068] The present application describes a number of embodiments, but the description is exemplary rather than limiting and it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible within the scope of the embodiments described in the present application. Although a number of possible combinations of features have been set forth herein, and discussed in the exemplary implementation, many other combinations of the disclosed features are possible. Unless specifically intended otherwise, any feature or element of any embodiment can be used in combination with any other feature or element of any other embodiment, or in combination with any other feature or element of the same embodiment.

[0069] The present application includes and contemplates combinations of features and elements known to those of ordinary skill in the art. The embodiments, features and elements disclosed herein can be combined with any conventional feature or element to form unique embodiments. Any feature or element of any embodiment can be combined with features or elements from other embodiments to form another unique embodiment. Accordingly, except as it can be otherwise limited, the scope of embodiments is not to be limited by the features and embodiments disclosed herein. Rather, the scope of embodiments is only to be limited by the claims and their equivalents. Moreover, modifications and variations are possible in light of the above teachings.

[0070] The present application provides a method for detecting a passenger state in a car, which is applied to an elevator system. The elevator system comprises a car and a touch sensing module. The touch sensing module is arranged in the car and is configured to sense whether a passenger in the car contacts the car and generate contact information when the passenger contacts the car. The method comprises the following steps:

[0071] In step 101, the position information of the passenger contacting the car is obtained based on the contact information sensed by the touch sensing module.

[0072] In step 102, the state of the passenger is determined based on the obtained position information of the passenger contacting the car.

[0073] The setting position of the touch sensing module can be set according to actual needs at a position where the passenger can contact the elevator car. For example, when it is actually needed to detect the mental state of the user in the car, the touch sensing module can be set on the inner wall around the car, so that when the passenger in the car leans against the inner wall of the car due to fatigue, the touch sensing module senses the position information of the contact between the passenger and the inner wall of the car, and then it can be determined that the passenger is in a poor mental state and is in a state of fatigue.

[0074] For another example, when it is actually needed to detect the movement and touch state of a child in the car, the touch sensing module can be set on the inner wall below a predetermined height (the predetermined height can be determined according to the average height of a child of a predetermined age) around the car and on the floor of the car, so that when the child enters the car and moves in the elevator due to being lively and active, the touch sensing module senses the position information of the contact between the child and the floor of the car, and then it can be determined that the child is in a state of movement, or when the child touches the inner wall of the elevator, the touch sensing module senses the position information of the contact between the child and the inner wall of the car, and then it can be determined that the child is in a state of touch, or when the child moves in the elevator and touches the inner wall of the elevator, the touch sensing module senses the position information of the contact between the child and the inner wall of the car and the floor of the car, and then it can be determined that the child is in a state of movement and touch. For another example, when it is actually needed to detect whether the user falls in the car, the touch sensing module can be set on the floor of the car, so that when the passenger in the car falls, the touch sensing module senses the position information of the contact between the passenger and the floor of the car, and then it can be determined that the passenger falls.

[0075] In some example embodiments, the elevator system can include a radar sensing module arranged in the car, and the method can include, before obtaining the position of the passenger contacting the car by using the contact information sensed by the touch sensing module:

[0076] obtaining the falling speed of the passenger by using the distance change between the passenger sensed by the radar sensing module;

[0077] obtaining the position of the passenger contacting the car by using the contact information sensed by the touch sensing module, including:

[0078] obtaining the position information of the passenger contacting the car by using the contact information sensed by the touch sensing module in response to the falling speed of the passenger being greater than a predetermined threshold.

[0079] For example, since the radar sensing module is arranged in the car, the descending speed of the passenger sensed by the radar sensing module refers to the descending speed of the passenger relative to the car. Since the passenger is generally in an upright state in the car, the distance change between the radar sensing module and the passenger sensed by the radar sensing module can be the distance change between the radar and the head of the passenger.

[0080] The radar sensing module can be a millimeter wave radar module. The ranging principle of the millimeter wave radar is to calculate the distance by measuring the time elapsed from emission to reception and the frequency change of the millimeter wave. The millimeter wave radar emits millimeter wave signals through an antenna, when these waves encounter an obstacle, part of the waves will be reflected back and received by the receiving antenna. Therefore, by measuring the time difference between the emitted signal and the received signal, the distance between the target object and the radar can be calculated.

[0081] According to the obtained position information of the passenger contacting the car, the state of the passenger is determined to include a falling state. When the passenger in the car falls quickly, the distance between the radar sensing module and the passenger sensed by the radar sensing module will change greatly, and the greater distance change corresponds to a greater descending speed, which is very likely to be a quick fall of the passenger, but there is still a possibility that the passenger feels tired standing and squats, or the passenger bends down to pick up the dropped object. If only the radar sensing module is used, the passenger state cannot be accurately determined, but the detection and processing method of the passenger state in the car provided in the embodiment of the disclosure only applies the radar sensing module to assist in determining the passenger fall, that is, when the descending speed of the passenger is greater than a preset threshold, the position information of the passenger contacting the car is obtained by using the contact information sensed by the touch sensing module, and then the state of the passenger is determined according to the obtained position information of the passenger contacting the car. Because the position information of the passenger contacting the car when the passenger squats and the position information of the passenger contacting the car when the passenger falls are necessarily different, the state of the passenger can be determined accordingly, and the situation of false judgment of falling due to the passenger squatting is avoided.

[0082] On the other hand, the above-mentioned state judgment of passenger fall assisted by the radar sensing module is only applicable to the situation that the passenger may fall quickly. For the slow fall of the passenger in the car, the distance between the millimeter wave radar module and the passenger sensed by the millimeter wave radar module will only change slightly, and the smaller distance change corresponds to a smaller descending speed. However, there are many reasons for the smaller descending speed, such as the common situation that the passenger looks down at the mobile phone, so it is impossible to determine whether the passenger falls.

[0083] In the above scheme of using the millimeter wave radar module to assist in passenger rapid falling state, in actual application, the touch sensing module can be first not started, and when the distance change between the radar sensing module and the passenger is obtained and the falling speed of the passenger is greater than the preset threshold, the touch sensing module is started to obtain the position information of the passenger contacting the car, and then the state of the passenger is determined according to the obtained position information of the passenger contacting the car.

[0084] In some example embodiments, the touch sensing module can be arranged on the floor of the car, and the radar sensing module can be arranged in the upper part of the internal space of the car.

[0085] Wherein, the upper part refers to the upper half of the internal space of the car.

[0086] For example, the radar sensing module can be arranged on the top of the car, or can be arranged on the connecting piece connected to the top of the car.

[0087] The radar sensing module and the touch sensing module cooperate with each other, and the application process schematic diagram of the passenger state detection and processing method in the car can be as shown in FIG. 2. The top box is arranged above the car, the control cabinet is arranged in the shaft, and the control cabinet is provided with a gateway. The top box is electrically connected with the radar sensing module, the touch sensing module and the control cabinet, and the control cabinet is electrically connected with the terminal. The radar sensing module sends the distance change between the passenger to the top box, and the touch sensing module sends the position information of the passenger contacting the car to the top box. The top box obtains the falling speed of the passenger (i.e. the falling speed relative to the car) by the distance change obtained by the radar sensing module, and then obtains the position information of the passenger contacting the car according to the contact information sensed by the touch sensing module, and further judges whether the passenger falls. If the passenger falls, the falling information is sent to the control cabinet, and the control cabinet reports to the client through the gateway.

[0088] In some example embodiments, the orthographic projection of the touch sensing module on the floor can coincide with the floor.

[0089] For example, in order to prevent the passenger's shoe sole from directly contacting the touch sensing module and causing damage to the touch sensing module, ensure that the touch sensing module maintains good sensing performance, and prolong the service life of the touch sensing module, a protective layer 20 can be further arranged on the touch sensing module 10. The arrangement of the protective layer does not affect the sensing performance of the touch sensing module. The schematic diagram of the arrangement can be as shown in FIG. 3.

[0090] When the protection layer 20 is arranged on the touch sensing module, the orthographic projection of the protection layer on the bottom plate 30 and the orthographic projection of the touch sensing module 10 on the bottom plate 30 are both coincident with the bottom plate 30.

[0091] In some example embodiments, the touch sensing module can include a plurality of touch sensing sub-modules divided in a grid form.

[0092] Each touch sensing sub-module is arranged to sense whether it is in contact with the passenger in the grid area where it is located and generate contact information when in contact with the passenger.

[0093] In order to better utilize the touch sensing module to obtain the position information of the passenger in contact with the car, the touch sensing module can be divided into a plurality of touch sensing sub-modules. A commonly used division method can be a grid form division, wherein the horizontal division intervals can be the same or different, and the vertical division intervals can be the same or different. In actual application, in order to facilitate implementation, the touch sensing module can be divided into a plurality of touch sensing sub-modules in a grid form with equal intervals (which can be equal horizontal intervals and equal vertical intervals).

[0094] Taking a touch sensing module of 1m*1m as an example, a schematic diagram of a plurality of touch sensing sub-modules divided in a grid form with equal intervals can be as shown in FIG. 4, i.e., the touch sensing module is divided into 100 touch sensing sub-modules.

[0095] In some example embodiments, the obtaining of the position information of the passenger in contact with the car by using the contact information sensed by the touch sensing module can include:

[0096] According to the position of each touch sensing sub-module generating contact information in the touch sensing module, the position distribution of the passenger in contact with the bottom plate of the car is obtained and used as the position information.

[0097] Since the touch sensing module is divided into multiple touch sensing sub-modules, when the passenger contacts the touch sensing module, the passenger actually contacts one or more touch sensing sub-modules, and the position of each touch sensing sub-module in the touch sensing module is fixed and unchangeable. Therefore, according to the position of the one or more touch sensing sub-modules (i.e., each touch sensing sub-module generating contact information) in the touch sensing module, the position distribution of the passenger contacting the floor of the car can be obtained. When the touch sensing sub-module generating contact information is one, the position distribution of the passenger contacting the floor of the car is single-point (i.e., single touch sensing sub-module) distribution, and when the touch sensing sub-module generating contact information is multiple, the position distribution of the passenger contacting the floor of the car is multi-point (i.e., multiple touch sensing sub-modules) distribution.

[0098] In some example embodiments, the working mode of the touch sensing module can include a point high mode, when the working mode of the touch sensing module is the point high mode, the contact information generated by each touch sensing sub-module can be output in the form of a high-level signal.

[0099] In actual application, the working mode of the touch sensing module can include a point high mode (abbreviated as point high), an automatic high-level mode (abbreviated as self high), a point low mode (abbreviated as point low), and an automatic low-level mode (abbreviated as self low).

[0100] The touch sensing module can be a capacitive touch sensing chip, when the touch sensing module is a capacitive touch sensing chip, the structure diagram of the capacitive touch sensing chip realizing multiple working modes can be as shown in FIG. 5, two lines connected with the capacitive touch sensing chip are respectively provided with a switch, i.e., switch A and switch B, and the working mode selection is realized by opening or closing of switch A and switch B. The correspondence between the opening and closing of switch A and switch B and the working mode can be as shown in Table 1.

[0101] Table 1

[0102] In some example embodiments, the state of the passenger includes a falling state, and the determination of the state of the passenger according to the obtained position information of the passenger contacting the car can include:

[0103] drawing a first image of the passenger contacting the car according to the obtained position information of the passenger contacting the car;

[0104] judging whether the passenger is in the falling state according to the obtained first image and a pre-set corresponding relationship between an image and a passenger state.

[0105] In some exemplary embodiments, the pre-set correspondence between images and passenger states can be set by collecting the graphic characteristics of images formed when a passenger falls and comes into contact with the car floor.

[0106] For example, in a scenario where a passenger suddenly loses consciousness (e.g., faints) and falls inside the elevator car, the passenger often falls to their left or right side, their body slightly curled up after the fall, forming an image resembling the letter "C" when in contact with the elevator car. In other scenarios, when a passenger suddenly feels unwell (e.g., heart attack, stroke), they often move closer to the elevator wall, then lean against it and gradually slide down until they fall. When a passenger falls in this way, their upper body may fall completely to the elevator floor, forming an image resembling the letter "C," or their upper body may lean against the wall with their legs in contact with the elevator car, forming an image resembling the symbol "<<." In other scenarios, a passenger falls into the elevator car due to unsteadiness while entering. When a passenger falls in this way, their arms and lower legs often contact the elevator floor in a similar graphic shape. Images. Therefore, images similar to the letter "C", images similar to the symbol "<<", and similar graphics can be used. The image is correlated with the passenger's fall state. In practical applications, a first image of the passenger's contact with the car is drawn based on the obtained position information of the passenger's contact with the car. The first image is then determined to resemble the letter "C", the symbol "<<", or something similar. When the image is viewed, it is determined that the passenger is in the fallen state.

[0107] Alternatively, the characteristics of the images formed when a passenger comes into contact with the car can be used to further categorize the causes of passenger falls, and different types of falls can be associated with images. For example, images resembling the letter "C" or the symbol "<<" can be associated with falls caused by physical discomfort, and similar shapes can be associated with falls caused by physical discomfort. The image corresponds to a fall caused by unsteady gait. In practical applications, if the first image is determined to be similar to the letter "C" or the symbol "<<", it is determined that the passenger is in a state of falling due to physical discomfort. When viewing the image, it is determined that the passenger is in a state of falling due to unsteady walking.

[0108] In some exemplary embodiments, the pre-set correspondence between the image and the passenger's state can be set by collecting the area characteristics of the image formed by the passenger falling and contacting the car floor.

[0109] For example, when a passenger normally stands in the car, only the feet and the car floor are in contact, thus the contact area is only the area of the soles of the feet, while when the passenger falls, the contact position with the car floor can include multiple parts of the body, which is generally significantly larger than the area of the soles of the feet. Therefore, the contact areas of passengers of different shoe sizes when taking the elevator can be counted, a reasonable area threshold is set according to the contact areas, and then the area threshold of the sole image is corresponded to the passenger falling state. In actual application, a first image of the passenger in contact with the car is drawn according to the obtained position information of the passenger in contact with the car, and when the area of the first image is determined to exceed the area threshold, it is determined that the passenger is in the falling state.

[0110] The detection processing method of the passenger state in the car provided by the embodiments of the present disclosure can select the working mode of the touch sensing module as point high level to implement. In actual application, the processing device shown in FIG. 6 can be used to process the obtained point high level signal. The processing device includes a touch sensing sub-module, a signal image analysis processing module, a programmable logic controller (PLC) module and an elevator main control board. The high level signal generated by the touch sensing sub-module is fed back to the signal register, and then the signal image analysis processing module obtains the position distribution of the passenger in contact with the floor of the car according to the position of each touch sensing sub-module generating the level signal in the touch sensing module as the position information, and further draws an image of the passenger in contact with the car according to the obtained position information of the passenger in contact with the car. Then, according to the pre-set corresponding relationship between the image and the passenger state, it is judged whether the passenger is in the falling state. When it is determined that the passenger is in the falling state, the corresponding execution signal (such as a return base station layer signal or a car door opening signal for controlling the car) is given to the PLC module, and the PLC module generates a corresponding instruction to the elevator main control board for actual execution.

[0111] In some example embodiments, the method or can include:

[0112] In response to determining that the state of the passenger is the falling state, the position distribution of the passenger in contact with the floor of the car is obtained again according to the position of each touch sensing sub-module generating the contact information in the touch sensing module as updated position information after a preset time arrives;

[0113] A second image of the passenger in contact with the car is obtained according to the updated position information;

[0114] According to the obtained second image and the corresponding relationship between the image and the passenger state, it is judged whether the passenger is still in the falling state.

[0115] In response to determining that the passenger is no longer in the falling state, the car can be controlled to run according to the floor selection information, which can be from the passenger who was in the falling state or from other passengers in the car. In response to determining that the passenger is still in the falling state, an alarm can be triggered.

[0116] In response to determining that the passenger is in the falling state, the car can be in a running state or in a non-running state. When the car is in the running state, the car is controlled to stop running until it is determined that the passenger is no longer in the falling state, and then the car can be controlled to run according to the floor selection information. When the car is in the non-running state, the car is controlled to remain in the non-running state until it is determined that the passenger is no longer in the falling state, and then the car can be controlled to run according to the floor selection information.

[0117] For the falling caused by unstable walking mentioned in the above embodiments, the passenger can often get up by himself, and for this case, no additional intervention can be performed. The detection method of the passenger state provided in the embodiments of the present disclosure determines that the passenger is in the falling state, and then determines again after a preset time, so as to avoid the problem that the passenger can get up by himself but is intervened too much.

[0118] The preset time can be set according to actual needs. In order to determine the passenger state as soon as possible, the preset time can be set to be small, so as to avoid the adverse consequences caused by not detecting the falling state that cannot get up by himself in time.

[0119] In addition, in some application embodiments, multiple preset time periods can be set for multiple detections, so as to better control the subsequent state of the passenger who is detected to be in the falling state for the first time.

[0120] For example, a first preset time and a second preset time are set, in response to the initial determination that the state of the passenger is a falling state, after the first preset time arrives, the position distribution of the passenger contacting the floor of the car is obtained again according to the position of each touch sensing sub-module generating contact information in the touch sensing module as updated position information; a second image formed by the passenger contacting the car is obtained according to the updated position information; whether the passenger is still in the falling state is determined according to the obtained second image and the corresponding relationship between the image and the passenger state; in response to the determination that the passenger is still in the falling state, after the second preset time arrives, the position distribution of the passenger contacting the floor of the car is obtained again according to the position of each touch sensing sub-module generating contact information in the touch sensing module as updated position information; a third image formed by the passenger contacting the car is obtained according to the updated position information; whether the passenger is still in the falling state is determined according to the obtained third image and the corresponding relationship between the image and the passenger state.

[0121] In some example embodiments, the method or can include:

[0122] In response to the determination that the state of the passenger is still a falling state, triggering an alarm and obtaining the running position of the car;

[0123] In response to the running position of the car being located in the leveling area, controlling the car door of the car to open;

[0124] In response to the running position of the car not being in the leveling area, controlling the car to return to the base station layer.

[0125] When the running position of the car is located in the leveling area, it means that the passenger is likely to have fallen into the car just after entering the car, at this time, the car door of the car is controlled to open, so that the fallen passenger can be quickly found by other passengers who will take the elevator, and other passengers can quickly assist the fallen passenger.

[0126] When the running position of the car is not in the leveling area, it means that the passenger may have fallen in the car during the operation of the elevator, at this time, the car is controlled to return to the base station layer, so that the passenger can be rescued at the base station layer.

[0127] In some example embodiments, the contact information can be obtained by periodically collecting the contact information sensed by the touch sensing module, the contact information can include: contact information corresponding to each collection time; the method or can include:

[0128] The contact information corresponding to each collection time is operated as follows: according to the position of each touch sensing sub-module generating the contact information in the touch sensing module at the collection time, the position distribution of the passenger contacting the floor of the car at the collection time is obtained as the position information corresponding to the collection time.

[0129] The information of the passenger is determined according to the changes of the position information corresponding to all collection times, and an operation corresponding to the obtained information of the passenger is performed.

[0130] In the process of entering the elevator, or in the process of moving in the car, or in the process of entering the elevator and moving in the car, the position information contacting the floor of the car changes constantly, and the change of the position information is closely related to the characteristics of the passenger, so that more personalized operations can be realized by using the correlation, and the use function of the elevator is enriched.

[0131] In some exemplary embodiments, the determination of the information of the passenger according to the changes of the position information corresponding to all collection times can include:

[0132] In the changes of the position information corresponding to all collection times, the interval between the position information corresponding to each two adjacent times is determined, and in response to the proportion of the number of intervals within a preset distance threshold and the total number of intervals exceeding a preset proportion, the passenger is determined to be a first type of passenger; wherein the first type of passenger includes a passenger whose height is less than a preset height threshold;

[0133] In response to the position information corresponding to each collection time corresponding to the changes of the position information corresponding to all collection times corresponding to each collection time corresponding to a single touch sensing sub-module, the passenger is determined to be a second type of passenger; wherein the second type of passenger includes a passenger sitting in a wheelchair;

[0134] In response to the rule of the changes of the position information corresponding to all collection times not conforming to a preset rule, the passenger is determined to be a third type of passenger; wherein the third type of passenger includes a passenger who is restricted from using the elevator.

[0135] Wherein, the proportion of the number of intervals within a preset distance threshold and the total number of intervals exceeding a preset proportion means that there are Y+1 collection times in total, the interval between the position information corresponding to each two adjacent collection times is Y, the number of intervals within the distance threshold in the Y intervals is X, and then X / Y is determined to exceed the preset proportion.

[0136] The change of the position information corresponding to all the collection time is the change of the position information corresponding to all the collection time after the passenger enters the elevator car. For example, assuming that passenger A enters the elevator car first, in this case, the change of the position information corresponding to all the collection time is the change of the position information corresponding to all the collection time after passenger A enters the elevator car, and then A leaves the elevator car and passenger B enters the elevator car, in this case, the change of the position information corresponding to all the collection time is the change of the position information corresponding to all the collection time after passenger B enters the elevator car.

[0137] In practical applications, the change of the position information corresponding to different types of passengers has its own characteristics, and the change of the position information corresponding to different types can be used to implement personalized operations on different types of passengers. For example, the step distance of the first type of passenger with a height less than a preset height threshold is small, and the small step distance produces a small corresponding moving distance, so the characteristics can be used to distinguish the first type of passenger from other types of passengers to implement appropriate operations on the first type of passenger. For another example, the second type of passenger including passengers using wheelchairs as a means of transportation, the wheelchair is round, and the position of each contact with the car floor is a single point, and the single point must fall into a single touch sensing sub-module, so the characteristics can be used to distinguish the second type of passenger from other types of passengers to implement appropriate operations on the second type of passenger. For another example, the third type of passenger including passengers restricted from using the elevator, the change of the position information of the third type of passenger in the car is different from that of passengers allowed to use the elevator (for example, passengers allowed to use the elevator often walk in an S curve when entering the elevator), so the characteristics can be used to distinguish the third type of passenger from other types of passengers to implement appropriate operations on the third type of passenger.

[0138] In some exemplary embodiments, the operation corresponding to the first type of passenger can include:

[0139] Turning off the call function, triggering an alarm and obtaining the running position of the car;

[0140] In response to the running position of the car being in the landing zone, controlling the car door to open;

[0141] In response to the running position of the car not being in the landing zone, controlling the car to return to the base station layer.

[0142] To ensure the safety of the first type of passenger (usually a child or a pet), the call function can be closed, an alarm triggered and the running position of the car obtained. If the running position is in the landing zone, it means that the first type of passenger entered the car alone, and the car door can be controlled to open to facilitate the discovery of other passengers who will take the elevator and facilitate their assistance. If the running position is not in the landing zone, it means that the first type of passenger entered the car with other passengers, and moved in the elevator after the other passengers got off, which is identified. At this time, the car is controlled to return to the base station layer so that the first type of passenger can get help at the base station layer.

[0143] In some example embodiments, when in a mode in which the call function is not opened to passengers who are below a preset height threshold, operations corresponding to the second type of passenger can include:

[0144] Opening the call function to the second type of passenger.

[0145] In some example embodiments, the judgment of different types of passengers can not be limited to the use of a touch sensing module alone, or can use a touch sensing module in combination with the use of a radar sensing module. For example, the elevator can be set to a mode in which the call function is not opened to passengers who are below a preset height threshold. After the passenger enters the car, the radar sensing module detects the height of the passenger. When the detected height of the passenger is below the preset height threshold, the call function is closed. However, in actual application, this mode can exclude the case of passengers in wheelchairs, so the change in position information sensed by the touch sensing module can be further used to determine whether the passenger is a passenger in a wheelchair. When the passenger is a passenger in a wheelchair, the call function is opened to the passenger.

[0146] In some example embodiments, operations corresponding to the third type of passenger can include:

[0147] Closing the call function.

[0148] In some example embodiments, the elevator can be intended to be used for a specific group of people and not for other groups of people, and therefore the detection method of the state of passengers in the car provided by the embodiments of the present disclosure can realize the exclusive use of the elevator by a specific group of people and avoid the use of the elevator by restricted groups of people or irrelevant groups of people.
