Wherein, the motion trend of the object can be detected by a motion trend detection model. When the movement trend of the object is from an area outside a hall to a door and/or the hall call key is pressed, the object can be regarded as being ready to use the elevator, namely, regarded as an outside hall call, and it should be noted that the door opening signal does not include the door opening signal generated when the door opening key inside the car is pressed, and is only limited to the door opening signal generated when the outside hall call is detected.

Example two
Fig. 2 is a flowchart of a signal priority determining method according to a second embodiment of the present invention, which is optimized based on the first embodiment of the present invention, and as shown in fig. 2, the signal priority determining method includes:
s201, collecting images of a detection area, wherein the detection area comprises an area outside a hall of an elevator and a car area.
S201 may specifically refer to S101 in the first embodiment, which is not described here.
S202, judging whether the object in the area outside the hall is located in the preset area range according to the image.
The preset area range belongs to an area outside a hall, the position of an object in the area outside the hall is determined according to the image, and then whether the object is located in the preset area range is determined according to the position of the object.
The preset area range of the area outside the hall can be an area range which takes the elevator door as the center of a circle and takes the preset distance as the radius in the area outside the hall, and can also be a range where the queuing area of the elevator is positioned. And judging whether the object in the area outside the hall is positioned in the range of the preset area according to the image, if so, executing S203, and if not, executing S204.
And S203, taking the object as a ladder waiting object.
The elevator waiting object is an object to be used for an elevator, and is located in an area outside a hall, i.e., a hall. However, the range of the area outside the hall, which can be shot by the sensor, may be relatively large, for example, the area including the hall may be passed by a pedestrian who is not ready to use (ride) the elevator; further, since the hall area may be a common area for a plurality of elevators at the same time, an object located in the hall area is not necessarily an object to prepare for using an elevator. And when the object in the area outside the hall is positioned in the preset area range, taking the object as the elevator waiting object.
And S204, identifying the motion trend of the object.
And S205, when the movement trend of the object is from the area outside the hall to the door, the object is taken as a waiting object.
If the object in the area outside the hall does not belong to the preset area range of the area outside the hall, but the moving trend of the object is from the area outside the hall to the door, the object is ready to use the elevator, and therefore the object can be used as the elevator waiting object.
The motion trend of the object can be identified according to a motion trend model, and can also be determined in the following way:
the method comprises the steps of obtaining position points of an object in each acquisition cycle, calculating the distance between each position point and a landing door, calculating the distance difference value between two adjacent distances, and determining the movement trend of the object to be from an area outside a hall to the landing door when a plurality of continuous distance difference values are larger than preset distance values.
The condition that a plurality of continuous distance difference values are larger than the preset value is set to be distinguished from the condition that the object is close to the elevator but is not ready to use the elevator, for example, when the object is ready to use the elevator, the object usually moves straight to the elevator, and the distance difference value of two adjacent distances is larger; when the object is not ready to use the elevator, for example, the object is only ready to pass a path beside the elevator or take an elevator opposite to the elevator (different elevators can reach different floors), the object does not go straight to the elevator, and the distance difference between two adjacent distances is small. The preset distance value may be set according to the shape of the road in the hall outside area, the position of the elevator in the hall outside area, and the like, which is not limited by the embodiment.
When it is determined that the movement tendency of the object is from the area outside the hall to the door, it can be determined that the object is ready to use the elevator, i.e. the object is a waiting object.
And S206, calculating the number of the elevator waiting objects to obtain the number of the elevator waiting objects.
And counting the number of the elevator waiting objects to obtain the number of the elevator waiting objects.
And S207, when the number of the objects in the elevator car is in the preset first interval, determining that the priority of the door opening signal of the elevator door is higher than the priority of the door closing signal of the elevator door.
In this embodiment, three intervals are set as a parameter for measuring the full load degree of the car, the three intervals are respectively a preset first interval, a preset second interval, and a preset third interval, and the values of the three intervals are arranged from small to large, that is, the value in the preset first interval is smaller than the value in the preset second interval, and the value in the preset second interval is smaller than the value in the preset third interval. Specifically, the ranges of the three sections can be set according to the elevator riding comfort level, the number of people checking the elevator, and the like. Illustratively, the number of nuclear loads of the elevator car is 12, and a first zone is set to [0,5], a second zone to [6, 10], and a third zone to [11, 12]. The third zone may also be the number of core loads of the car.
For the convenience of understanding, the full load degree of the car can be divided into three levels of low degree, medium degree and high degree, and the corresponding number of the objects in the car corresponds to three intervals respectively.
When the number of the objects in the elevator car is in the preset first interval, the full load degree of the elevator car is shown to be low, and in order to improve the utilization rate of the elevator, the objects waiting for the elevator can be allowed to enter the elevator car at the moment, so that the priority of the door opening signal of the door of the elevator is higher than the priority of the door closing signal.
And S208, when the number of the objects in the car is in the preset second interval, determining the priority of the door opening signal and the door closing signal according to the object type of the objects in the car area and the number of the elevator waiting objects.
When the number of objects in the car is in the preset first interval, it indicates that the full load degree of the car is moderate, that is, the environment in the elevator is relatively loose, and there is a space for receiving the object of waiting for the elevator. The type of the object can have an additive effect on the full load degree of the car, and then the additive effect of the specific type on the full load degree of the car can be set according to actual requirements. When the number of the objects in the car is in the preset second interval, determining the priority of the door opening signal and the door closing signal according to the object type and the number of the elevator waiting objects of the car area, wherein the priority can be used for judging whether the object type of the objects in the car area comprises a specific type or not, if so, calculating the full load degree of the car area according to the addition effect corresponding to the specific type, then judging the number of the elevator waiting objects which can be accepted according to the full load degree of the car, if the number is greater than the number of the elevator waiting objects, determining that the priority of the door opening signal is higher than the priority of the door closing signal, and if the number is less than the number of the elevator waiting objects, determining that the priority of the door closing signal is higher than the priority of the door opening signal.
In an optional embodiment of the present invention, the object type includes a target type, and the determining of the priority of the door opening signal and the door closing signal according to the object type of the object in the car area and the number of the elevator waiting objects includes:
it is determined whether the object type of the object of the car zone includes a target type. The target type of object is an object that requires a relaxed environment. If yes, calculating the occupied area when a loose environment is formed according to the object information of the objects in the car area; and determining the priority of the door opening signal and the door closing signal according to the area and the occupied area of the elevator car area and the number of the elevator waiting objects.
The target type is a specific type having an additive effect on the area of the calculation object in the car, namely, an object needing a loose environment, or an object not easy to squeeze, such as an old person, a baby, a pregnant woman, a wheelchair rider, a rigid large object, and the like, and the occupied area of the car area is calculated according to the area additive effect of the specific type to serve as the occupied area when the loose environment is formed. For example, when a child has a real footprint of 0.2m 2 The actual occupied area of other objects is 1m 2 In order to prevent children from being squeezed, the addition effect (addition coefficient) of the 'children' is set to be 2, and the occupied area of the children is 0.4m 2 Then the calculated occupied area of the object of the car area is 1.4m 2 . Then, the receivable waiting time is judged according to the difference value between the area of the car area and the occupied areaAnd if the number of the elevator objects is less than the number of the elevator waiting objects, determining that the priority of the door opening signal is higher than that of the door closing signal.
The object information also comprises the projection area of the object and the elevator taking state of the object, and the occupied area when the loose environment is formed is calculated according to the object information of the object in the car area, and the method comprises the following steps: calculating the sum of the projection areas of the objects in the car area to obtain the total projection area; determining the number and weight coefficients of the objects of the target type; and calculating the product of the number and the weight coefficient of the target type objects and the preset loose environment area, and calculating the sum of the product and the total projection area to obtain the occupied area when the loose elevator-taking environment is formed.
In one example, the total projected area of the object in the current car region may also be determined according to the projected area of the object and the elevator taking state of the object, where the elevator taking state includes entering the car and exiting the car, that is, the projected areas of the objects entering and exiting the car are accumulated, the elevator taking state is that the coefficient of the projected area of the entering car is 1, and the coefficient of the projected area of the exiting car is-1.
The weighting coefficient is set in advance for the target type, for example, the target type is old people, the weighting coefficient is 1.8, the target type is children, and the weighting coefficient is 1.3. Weights are set for different types according to actual requirements. The preset loose environment area is a margin area of each target type, that is, the preset loose environment area is the same regardless of the elderly and children, and only the occupied areas of the objects of different target types are adjusted by the weight coefficients.
Wherein, confirm the priority of signal and the signal of closing the door of opening the door according to the area, the area occupied and the ladder object quantity of waiting of car region, include: calculating the difference value between the area of the cage area and the occupied area to obtain the residual elevator taking area; obtaining the number of the remaining elevator-taking objects according to the remaining elevator-taking area and the area of a preset unit object; judging whether the number of the elevator waiting objects is less than the number of the remaining elevator taking objects or not; if so, determining that the priority of the door opening signal is higher than that of the door closing signal; if not, determining that the priority of the door closing signal is higher than that of the door opening signal.
The preset unit object area is the average area occupied by a preset object, and since the height and the thinness of each object may be different, the average area can be used to estimate the area of the object. After the remaining elevator taking area is obtained through calculation, the ratio of the remaining elevator taking area to the preset unit object area can be calculated to obtain the number of the remaining elevator taking objects. If it is determined that the target type object exists in the car, that is, if the object requires a soft environment, if there are many elevator waiting objects and the number of elevator waiting objects entering the car cannot be controlled when the doors are opened, the soft environment may be damaged. Therefore, under the condition that the target type objects exist in the car, only when the number of the elevator waiting objects in the area outside the hall is smaller than the remaining elevator taking number, the priority of the door opening signal is determined to be higher than that of the door closing signal, at the moment, the elevator waiting objects all enter the car, the loose environment cannot be damaged, the loose environment of the target objects can be guaranteed, when the target type objects are passengers such as old people, children and pregnant women, the elevator taking feeling of the objects is improved, the safety of the passengers is guaranteed, and when the target type objects are rigid large objects, the situation that other passengers are crowded in the car and are extruded and collided with the rigid objects to cause discomfort can be avoided.
And S209, when the number of the objects in the car is in a preset third interval, determining that the priority of the door closing signal is higher than that of the door opening signal.
When the number of the objects in the car is in the preset third interval, the full-load degree of the car is indicated as the height, and at the moment, the priority of the door closing signal can be determined to be higher than the priority of the door opening signal, so that the passengers in the car are prevented from being excessively extruded.
It should be noted that, when the section where the number of objects in the car is located is determined, whether the number of objects in the car is in a certain section may be sequentially determined, for example, first, whether the number of objects in the car is in the first section is determined, if not, whether the number of objects in the car is in the second section is determined, and if not, it may be determined that the number of objects in the car is in the third section.
In the embodiment, the priorities of the door opening signal and the door closing signal are determined according to the number of objects in the car, the number of elevator waiting objects and the object type of the objects in the car area, when the objects are target objects in a loose environment, and under the condition that the objects of the target type exist in the car, the priority of the door opening signal is higher than that of the door closing signal only when the number of the elevator waiting objects in the area outside the hall is determined to be smaller than the residual elevator taking number, so that the loose environment of the car area is ensured, the elevator taking experience of passengers is improved, the safety is also improved, the control logic is optimized, and the priority processing of the door opening signal and the door closing signal is more reasonable.

s301, collecting images of a detection area, wherein the detection area comprises an area outside a hall of an elevator and a car area.
An image of the detection area is acquired by the sensor. The detection area is an area within the viewing angle range of the sensor.
S302, object information of an object using an elevator in the detection area is determined according to the image.
The object information comprises the number and the type of objects in the car of the car area, and the projection area of the objects.
And S303, calculating the projection area of the object in the car area to obtain the total projection area.
The total projection area of the object in the current car area can be determined according to the projection area of the object and the elevator taking state of the object, the elevator taking state comprises entering the car and exiting the car, namely the projection area of each object entering and exiting the car is accumulated, the coefficient of the projection area of the entering car is 1 in the elevator taking state, and the coefficient of the projection area of the exiting car in the elevator taking state is-1.
And S304, determining the priority of door opening signals and door closing signals of the elevator doors according to the total projected area and the area of the elevator car area.
In an alternative embodiment of the present invention, determining the priority of door opening and closing signals of doors of an elevator based on the projected total area and the area of the car area includes:
judging whether the difference value between the area of the car area and the total projection area is larger than a reserved area or not; if so, determining that the priority of the door opening signal of the elevator door is higher than the priority of the door closing signal of the elevator door; if not, determining that the priority of the door closing signal is higher than that of the door opening signal.
Since the fat and thin degrees of the objects to be used for elevator riding are not uniform, it may be inappropriate to count the objects to be used for elevator riding to determine whether the current car is fully loaded, for example, the full loading degree when a plurality of objects with larger body girth exist in the car is substantially greater than the full loading degree of the objects with smaller body dimension in the car, and therefore, if the current car is determined to be fully loaded only by counting the objects to be used for elevator riding, the elevator riding experience of the objects in the car or the objects waiting for elevator may be affected. Therefore, the present application judges the full load degree of the current car through the projection area of the object, namely judges whether the difference between the area of the car region and the total projection area is larger than the reserved area, and the reserved area can be the average projection area of one object, namely, although the total projection area is smaller than the area of the car region, the difference between the two still can at least accommodate one object, so as to allow the accommodation of the newly-added elevator waiting object.
In another alternative embodiment of the present invention, the priority of the door opening signal and the door closing signal of the doors of the elevator is determined according to the projected total area and the area of the car region, further comprising:
judging whether the difference value between the area of the car area and the total projection area is larger than a reserved area or not; if so, determining that the priority of the door opening signal of the elevator door is higher than the priority of the door closing signal of the elevator door; if not, detecting the area of a vacant area communicated with the elevator door in the elevator car area according to the image; judging whether the area of the vacant area is larger than the reserved area or not; if so, determining that the priority of the door opening signal is higher than that of the door closing signal; if so, determining that the priority of the door closing signal is higher than that of the door opening signal.
The present embodiment is an embodiment optimized based on the above embodiment. In this embodiment, the projected area of each object may be considered as the maximum footprint of the object, but generally speaking, the actual footprint of the object (e.g., passenger) may be smaller than the projected area, i.e., the actual footprint may be smaller than the projected area after the object has been positioned, shaped or spaced from an adjacent object, e.g., the projected area may be larger due to the bulkiness of the clothing worn by the passenger, the actual footprint of the passenger itself may be smaller, and further, for example, when multiple passengers are standing next to each other, the total footprint of the multiple passengers may be smaller than the total projected area, i.e., "vacated" space. Therefore, the difference between the area of the car area and the total projected area is smaller than the reserved area, the area of the vacant area in the car area, which is communicated with the elevator door, can be detected, that is, whether the object in the car has a "vacated" vacant area is determined, if yes, whether the "vacated" vacant area is larger than the reserved area is determined, and the reserved area can be the average projected area of one object, that is, although the total projected area is smaller than the area of the car area, the difference between the two areas still can at least accommodate one object, so as to allow the accommodation of a newly added elevator waiting object. This embodiment determines the priority of door opening and closing signal through combining the area of the vacant region that communicates with the door in projection area and the car region, can make the priority processing of door opening and closing signal more accord with the actual scene of riding the ladder, has optimized control logic, avoids only judging the condition that still has great vacant region when full load degree of elevator according to the total area of projection, also can improve the availability factor of elevator.
