Description

Technical Field

[0001] The present invention relates to the field of intelligent lighting, and in particular to an intelligent lighting brightness adjustment method and a property monitoring system. Background Art

[0002] In recent years, with the rapid development of offline service industry, how the property management office of residential community cooperates with couriers or movers in work has become a hot topic. As a property management office, it does not have direct management authority to manage or restrict couriers or movers, and the property staff of the property management office directly negotiate with couriers or movers face to face, which is easy to cause disputes and conflicts, thereby increasing the management cost of the property management office and may even affect the interests of the owners of the community.

[0003] For example, during the peak hours of elevator use, most residential communities do not restrict couriers or movers from going up and down the stairs. In recent years, the users of elevators are not only mainly residents, but also residents, couriers, movers, etc. use them together during peak hours. This trend of change has put forward higher requirements for the efficiency of elevators in residential communities to carry residents. However, the industry has not yet put forward a reasonable technical solution to solve the above problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is: how to design an intelligent lighting brightness adjustment method and a property monitoring system, which can significantly improve the efficiency of elevators in carrying residents in the community when couriers use flatbed trucks or movers move furniture, thereby reducing the unreasonable occupancy of elevators.

[0005] In the process of providing technical services for residential communities, the inventor discovered that in order to improve work efficiency, when couriers use flatbed trucks to go up and down the stairs in residential communities, or when movers move furniture up and down the stairs, they are prone to unreasonable behavior of excessively occupying elevators, that is, violations. However, it is difficult for property staff of the property management office to observe such violations, and the property management office itself has no authority to prevent couriers or movers from occupying elevators next time. For example, the notice posted by the property management office that "those who use elevators illegally will be fined" is useless (even if the owners' committee introduces relevant systems, it has no binding force on couriers or movers in actual implementation); if the use of elevators is forcibly restricted, such as stopping a courier who uses the elevator illegally in the community, it is easy for the courier to feel that time is wasted or his interests are infringed, leading to disputes and conflicts. For this reason, the present application proposes an intelligent lighting brightness adjustment method and a property monitoring system for elevator space, which can significantly improve the efficiency of elevators in the community in carrying residents in the scenario where couriers use flatbed trucks or movers move furniture, thereby reducing the unreasonable occupation of elevators.

[0006] In a first aspect, the present invention proposes an intelligent lighting brightness adjustment method, which is used for a control unit of a property monitoring system, and the control unit is connected to a lighting unit.

[0008] A further technical solution is that if the spatial scene covered by the lighting unit meets the first preset condition, the lighting state of the lighting unit is adjusted, including: if the spatial scene covered by the lighting unit meets the first preset condition, the lighting state of the lighting unit is adjusted from a first state to a second state.

[0009] Its further technical solution is that the residential building corresponding to the residential passenger elevator includes a residential freight elevator and at least two residential passenger elevators, the control unit is connected to the camera in the residential freight elevator, and the lighting state of the camera belongs to conventional control and is different from the camera; the control unit is also connected to the cameras in at least two residential passenger elevators, and the cameras are used to shoot the spatial scenes of the residential passenger elevators; the method also includes: judging whether the spatial scene covered by the lighting unit in the second state meets the second preset condition or the third preset condition; when the spatial scene covered by the lighting unit in the second state meets the second preset condition, keeping the lighting state of the lighting unit in the second state, and then closing the automatic door of the residential passenger elevator; when the spatial scene covered by the lighting unit in the second state meets the third preset condition, after waiting for a preset time, adjusting the lighting state of the lighting unit to the first state, and then closing the automatic door of the residential passenger elevator.

[0010] Its further technical solution is that the camera is used to shoot the spatial scene of a residential passenger elevator to form an elevator live video, the live frame screenshot of the elevator live video shows the car floor of the residential passenger elevator, and the lighting unit is connected to the ceiling of the residential passenger elevator; the spatial scene covered by the lighting unit in the second state is judged to meet the second preset condition or the third preset condition, including: identifying the situation where a common contact area appears between the upper limbs of the passengers and the objects to be carried in the residential passenger elevator, judging the passengers corresponding to the situation as carriers, setting the carriers and the objects to be carried to constitute a carrier body, and judging the passengers other than the carriers as independent passengers; judging whether the proportion of the area of ​​the car floor occupied by the carrier body exceeds the preset proportion value; if the proportion of the area of ​​the car floor occupied by the carrier body exceeds the preset proportion value, Keep the automatic door of the residential passenger elevator in an open state; if the proportion of the area of ​​the car floor occupied by the transport body does not exceed the preset ratio, determine whether the elevator on-site video corresponding to the spatial scene covered by the lighting unit in the second state meets the condition that only the transport body is included but no independent passengers, or whether it meets the condition that both the transport body and the independent passengers are included; if the elevator on-site video corresponding to the spatial scene covered by the lighting unit in the second state meets the condition that only the transport body is included but no independent passengers, then determine that the spatial scene covered by the lighting unit in the second state meets the second preset condition; if the elevator on-site video corresponding to the spatial scene covered by the lighting unit in the second state meets the condition that both the transport body and the independent passengers are included, then determine that the spatial scene covered by the lighting unit in the second state meets the third preset condition.

[0011] Its further technical solution is that the property monitoring system also includes an automatic door alarm module and multiple monitoring displays, the control unit is connected to the automatic door alarm module and the multiple monitoring displays, the multiple monitoring displays include at least two monitoring displays for displaying elevator live videos, and the intelligent lighting brightness adjustment method also includes: when the automatic door alarm module issues an alarm, judging whether the automatic door in the space scene covered by the lighting unit is in contact with the blocking subject; if the automatic door in the space scene covered by the lighting unit is in contact with the blocking subject, adjusting the lighting state of the lighting unit to a third state; wherein the luminous flux index of the second state is less than the luminous flux index of the first state, and the luminous flux index of the third state is less than half of the luminous flux index of the second state; controlling the monitoring display for displaying the elevator live video to receive the video stream captured by the camera, and displaying the elevator live video with the lighting state of the third state in the video stream.

[0012] A further technical solution is that if the automatic door in the space scene covered by the lighting unit contacts the blocking body, the lighting state of the lighting unit is adjusted to a third state, including: if the automatic door in the space scene covered by the lighting unit contacts the blocking body, the lighting state of the lighting unit is adjusted to an off state.

[0013] A further technical solution is that, based on at least one of the video screenshot images, determining whether the spatial scene covered by the lighting unit meets the first preset condition, includes: receiving N video screenshot images in which the feature similarity of the object to be loaded in the image exceeds the preset activation similarity, and taking an image with the highest feature similarity among the N video screenshot images as the scene representative image; processing the scene representative image to determine whether the similarity between the object to be loaded in the scene representative image and the preset over-standard object exceeds the preset object similarity threshold; if the similarity between the object to be loaded in the scene representative image and the preset over-standard object exceeds the preset object similarity threshold, determining that the spatial scene covered by the lighting unit meets the first preset condition.

[0014] A further technical solution is that the scene representative image is processed to determine whether the similarity between the object to be carried in the scene representative image and the preset over-standard items exceeds a preset item similarity threshold, including: after convolution processing of the scene representative image, at least three dimension spaces are obtained; two of the at least three dimension spaces are selected as target spaces according to preset indicators; the degree of deviation between the two target spaces is calculated, and a Gaussian pyramid is constructed according to the degree of deviation; feature point positioning of the Gaussian pyramid is performed to obtain multiple target feature points; corresponding feature attributes are generated according to the multiple target feature points, the similarity between the feature attributes and the preset over-standard items is calculated, and it is determined whether the similarity exceeds the preset item similarity threshold.

[0015] In a second aspect, the present invention provides a property monitoring system, wherein a control unit of the property monitoring system is used to execute the method described in the first aspect.

[0016] To sum up, in recent years, with the rapid development of offline service industries, how the property management offices of residential communities cooperate with couriers or movers in their work has become a hot topic of concern; during the peak hours of going up and down the elevator, most residential communities will not restrict couriers or movers from going up and down the stairs. In recent years, the users of elevators are not only mainly residents, but also residents, couriers, movers and others use them together during peak hours. This changing trend has put forward higher requirements on the efficiency of elevators in the community in carrying residents; the present application solves the above problems and can significantly improve the efficiency of elevators in the community in carrying residents when couriers use flatbed trucks or movers use furniture, thereby reducing the unreasonable occupation of elevators.

An embodiment of the present invention provides an intelligent lighting brightness adjustment method, the method is used for a control unit of a property monitoring system, the control unit is connected to a lighting unit, the lighting unit is arranged in a residential passenger elevator, the intelligent lighting brightness adjustment method comprises:

[0032] S1, judging whether the space scene covered by the lighting unit meets a first preset condition according to the internal situation of the residential passenger elevator.

[0033] S2: If the spatial scene covered by the lighting unit does not meet the first preset condition, the lighting state of the lighting unit is kept unchanged.

[0034] S3: If the spatial scene covered by the lighting unit meets a first preset condition, adjust the lighting state of the lighting unit.

[0035] In one embodiment, judging whether the spatial scene covered by the lighting unit meets the first preset condition according to the internal situation of the residential passenger elevator includes:

[0036] S101, receiving at least one video frame image of a spatial scene covered by the lighting unit.

[0037] S102: Determine, based on at least one of the video screenshots, whether a spatial scene covered by the lighting unit meets a first preset condition.

[0038] In the above solution, at least one video frame image of the spatial scene covered by the lighting unit is received, and the spatial scene may be inside an elevator, that is, at least one video frame image of the spatial scene inside the elevator covered by the lighting unit is received.

[0039] In one embodiment, judging whether the spatial scene covered by the lighting unit meets the first preset condition based on at least one of the video screenshots includes: judging whether the spatial scene covered by the lighting unit meets the first preset condition based on a video screenshot of the side wall of the elevator where the passengers are closest. In another embodiment, judging whether the spatial scene covered by the lighting unit meets the first preset condition based on a video screenshot of the elevator car floor with the largest coverage area.

[0040] In one embodiment, if the spatial scene covered by the lighting unit meets a first preset condition, adjusting the lighting state of the lighting unit includes:

[0041] S301: If the spatial scene covered by the lighting unit meets a first preset condition, adjust the lighting state of the lighting unit from a first state to a second state.

[0042] In one embodiment, the residential building corresponding to the residential passenger elevator includes a residential freight elevator and at least two residential passenger elevators, the control unit is connected to a camera in the residential freight elevator, the lighting state of the camera belongs to conventional control and is different from the camera, the control unit is also connected to the cameras in at least two residential passenger elevators, and the cameras are used to shoot the spatial scenes of the residential passenger elevators; the intelligent lighting brightness adjustment method includes:

[0043] S1, judging whether the space scene covered by the lighting unit meets a first preset condition according to the internal situation of the residential passenger elevator.

[0044] S2: If the spatial scene covered by the lighting unit does not meet the first preset condition, the lighting state of the lighting unit is kept unchanged.

[0045] S3: If the spatial scene covered by the lighting unit meets a first preset condition, adjust the lighting state of the lighting unit.

[0046] S401, determining whether the spatial scene covered by the lighting unit in the second state meets the second preset condition or the third preset condition.

[0047] S402, when the spatial scene covered by the lighting unit in the second state meets the second preset condition, the lighting state of the lighting unit is maintained in the second state, and then the automatic door of the residential passenger elevator is closed.

[0048] S403, when the spatial scene covered by the lighting unit in the second state meets the third preset condition, after waiting for a preset time, adjust the lighting state of the lighting unit to the first state, and then close the automatic door of the residential passenger elevator.

[0049] In the above scheme, after the step S3, the steps S401 to S403 are continued to be executed. The first state corresponds to the bright light state, and the second state corresponds to the dim light state. The luminous flux index of the dim light state is less than half of the luminous flux index of the bright light state. Furthermore, the second preset condition and the third preset condition are mutually exclusive; if the second preset condition is met, the elevator continues to operate in the dim light state; if the third preset condition is met, the elevator continues to operate in the bright light state after waiting for a preset time.

[0050] In another embodiment, if the spatial scene covered by the lighting unit meets the first preset condition, after adjusting the lighting state of the lighting unit from the first state to the second state, continue to judge whether the spatial scene covered by the lighting unit in the second state meets the second preset condition or the third preset condition.

[0051] In one embodiment, the residential freight elevator is used to carry objects to be carried including express flatbed trucks or target furniture (i.e., flatbed trucks or furniture) under normal circumstances, and the residential passenger elevator is used to carry objects to be carried in violation of regulations; the camera is used to capture a spatial scene of the residential passenger elevator to form an elevator live video, and a live frame shot of the elevator live video shows a car floor of the residential passenger elevator, and the lighting unit is connected to a ceiling of the residential passenger elevator; the step of determining whether the spatial scene covered by the lighting unit in the second state meets the second preset condition or the third preset condition comprises:

[0052] S501, identifying the situation where a common contact area occurs between the upper limbs of a passenger in a residential passenger elevator and the object to be loaded, determining the passenger corresponding to this situation as a carrier, setting the carrier and the object to be loaded together as a carrier body, and determining passengers other than the carrier as independent passengers.

[0053] S502, determining whether the proportion of the area of ​​the elevator floor occupied by the transport body exceeds a preset proportion value.

[0054] S503: If the proportion of the area of ​​the elevator car floor occupied by the transport body exceeds a preset proportion value, the automatic door of the residential passenger elevator is kept in an open state.

[0055] S504, if the proportion of the area of ​​the car floor occupied by the transport body does not exceed the preset proportion value, determine whether the elevator scene video corresponding to the spatial scene covered by the lighting unit in the second state meets the condition of only including the transport body and not including independent passengers, or whether it meets the condition of including both the transport body and independent passengers.

[0056] S505, if the elevator on-site video corresponding to the spatial scene covered by the lighting unit in the second state meets the condition that it only contains the transporting body and does not include independent elevator passengers, it is determined that the spatial scene covered by the lighting unit in the second state meets the second preset condition.

[0057] S506: If the elevator on-site video corresponding to the spatial scene covered by the lighting unit in the second state meets the condition of including both the transporting body and the independent elevator passengers, it is determined that the spatial scene covered by the lighting unit in the second state meets the third preset condition.

[0058] In the above solution, the residential passenger elevator includes an automatic door and a car floor, and the cameras in the residential passenger elevator are all located on the side away from the automatic door; the spatial scene corresponds to the elevator live video, that is, the elevator live video displays the spatial scene, and the car floor, as a component of the residential passenger elevator, is also displayed in the elevator live video. The basis for judging the target furniture can be size specifications and maximum height, and the specific basis is known to those skilled in the art.

[0059] Among them, the upper limbs of the passenger are identifiable by the prior art, and there is a common contact area between the upper limbs of the passenger and the object to be loaded, or there is a common contact area, that is, the passenger has carried the object to be loaded; the common construction of the carrying subject can be set in the same detection frame for the carrier and the object to be loaded to constitute the same carrying subject. The technical effect is that the carrier can be accurately screened out from the elevator space, and the screened carrier and the object to be loaded can be used together as the judgment condition for the next step.

[0060] In the above scheme, the first state corresponds to the bright light state, and the second state corresponds to the dim light state. The luminous flux index of the dim light state is less than half of the luminous flux index of the bright light state. In the elevator on-site video, when it meets the conditions of including both the transport subject and the independent elevator passengers, regardless of whether the transporter leaves with the object to be carried next, that is, regardless of whether the transport subject is still in the residential passenger elevator next, the residential passenger elevator will be adjusted to the bright light state to avoid affecting the normal use of the elevator by independent elevator passengers due to individual violations. The independent elevator passengers include owners, residents, couriers, etc., and their number in a residential passenger elevator can be zero or one or more. For example, the carrying capacity of a standard residential passenger elevator is about twelve people.

[0061] In one embodiment, the situation where the upper limbs of the passengers in the residential passenger elevator cross or overlap with the objects to be loaded is identified, and the passengers corresponding to this situation are determined as carriers, and the carriers and the objects to be loaded are set to constitute the carrier body, and the passengers other than the carriers are determined as independent passengers. If the proportion of the area of ​​the car floor occupied by the carrier body exceeds the preset proportion value, the automatic door of the residential passenger elevator is kept in the open state, which is equivalent to being at the scene of illegal use of the elevator. At this time, the property personnel can be notified by signal to handle on the spot. The specific signal communication means are known to those skilled in the art.

[0062] In one embodiment, the property monitoring system further includes an automatic door alarm module and multiple monitoring displays. The control unit is connected to the automatic door alarm module and the multiple monitoring displays, and the multiple monitoring displays include at least two monitoring displays for displaying elevator live videos; wherein each monitoring display may display pictures corresponding to multiple cameras, or may only display one picture, and whether one picture or multiple pictures is set by the operator; after the step S506, the intelligent lighting brightness adjustment method further includes:

[0063] S601, when the automatic door alarm module sounds an alarm, determine whether the automatic door in the space scene covered by the lighting unit is in contact with a blocking body.

[0064] S602: If the automatic door in the space scene covered by the lighting unit contacts the blocking body, adjust the lighting state of the lighting unit to the third state.

[0065] S603, controlling the monitoring display for displaying the elevator live video to receive the video stream captured by the camera, and displaying the elevator live video in the video stream with the lighting state being the third state.

[0066] The luminous flux index of the second state is less than that of the first state, and the luminous flux index of the third state is less than half of that of the second state. The definition of luminous flux is known to those skilled in the art; the luminous flux index of the third state is the state with the lowest brightness, at which the brightness of the entire elevator space is less than the brightness of the elevator space in most cases.

[0067] In one embodiment, if the automatic door in the space scene covered by the lighting unit contacts the blocking body, the lighting state of the lighting unit is adjusted to the third state, including: if the automatic door in the space scene covered by the lighting unit contacts the blocking body, the lighting state of the lighting unit is adjusted to the off state. After the lighting state of the lighting unit is adjusted to the off state, the property staff can more intuitively identify the scene of illegal use of the elevator, and in the subsequent negotiations with the couriers delivering small and medium-sized items, it is easier to be reasonable and well-founded, thereby reducing the possibility of similar violations continuing to occur.

[0068] In one embodiment, if the automatic door in the space scene covered by the lighting unit is not in contact with the blocking body, maintenance requirement information is generated and stored; this indicates that the elevator has a fault, so the maintenance requirement information needs to be passed on to the property staff.

[0069] The technical effect of the above scheme is: when the carrier and the object to be carried are identified, there is still a situation of illegal use of the elevator, that is, the courier who delivers small and medium-sized items, the "small and medium-sized items" carried by him do not belong to the category of objects to be carried, but in order to improve the delivery efficiency, the courier who delivers small and medium-sized items will use the "small and medium-sized items" as a blocking body to hold the automatic door of the elevator, resulting in the residents on other floors being unable to use the elevator normally. At this time, the residents waiting for the elevator on the first floor do not know why the elevator moves slowly (the actual reason is that the courier holds the automatic door of the elevator), which may eventually lead to crowding of residents on the first floor or cause complaints to the property; this embodiment can solve the above problem. The property staff can intuitively see the illegal use of the elevator in the monitoring room of the property according to the elevator status displayed on multiple monitoring displays. Considering that the energy of the property staff is limited, some property staff have other work to do in the monitoring room, or occasionally get distracted and cannot keep staring at the display. Compared with the prior art, the scheme described in this embodiment will not affect other daily work of the property staff in identifying illegal use of the elevator. It is more intuitive and more efficient.

[0070] In one embodiment, judging, based on at least one of the video frame images, whether the spatial scene covered by the lighting unit meets a first preset condition includes:

[0071] S801, receiving N video frame images whose feature similarity of the object to be carried in the image exceeds a preset activation similarity, and taking an image with the highest feature similarity among the N video frame images as a scene representative image.

[0072] S802, processing the scene representative image to determine whether the similarity between the object to be carried in the scene representative image and the preset over-standard object exceeds a preset object similarity threshold.

[0073] S803: If the similarity between the object to be carried in the scene representative image and the preset over-standard object exceeds a preset object similarity threshold, it is determined that the spatial scene covered by the lighting unit meets the first preset condition.

[0074] In one embodiment, the processing of the scene representative image to determine whether the similarity between the object to be carried in the scene representative image and the preset over-standard object exceeds a preset object similarity threshold includes:

[0075] S901, after performing convolution processing on the scene representative image, at least three size spaces are obtained.

[0076] S902: Select two of the at least three size spaces as target spaces according to a preset indicator.

[0077] S903: Calculate the degree of deviation between the two target spaces, and construct a Gaussian pyramid according to the degree of deviation.

[0078] S904, positioning feature points on the Gaussian pyramid to obtain multiple target feature points.

[0079] S905, generating corresponding feature attributes according to the plurality of target feature points, calculating the similarity between the feature attributes and the preset over-standard items, and determining whether the similarity exceeds a preset item similarity threshold.

[0080] In the above scheme, part of the objects to be loaded are objects to be loaded, and the other part are not objects to be loaded, that is, they can enter the residential passenger elevator normally. The passengers or objects to be loaded gradually enter the residential passenger elevator from the outside to the inside, and then gradually approach the camera, so the feature similarity gradually approaches the real similarity. Furthermore, the dimension space can be an image scale space. The preset over-standard items can be derived from a database, and the preset over-standard items in the database can be items that meet the characteristics of express flatbed trucks, or items that meet the characteristics of large furniture, which are specifically known to those skilled in the art.

[0081] In one embodiment, the present invention further provides a property monitoring system, wherein the control unit of the property monitoring system is used to execute the method described in any of the above embodiments. The property monitoring system can intuitively identify the illegal behavior of excessive elevator occupancy, thereby significantly improving the efficiency of elevators carrying residents in the community, thereby reducing the unreasonable occupancy of elevators.
