Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of elevators, and in particular relates to a device for reducing the number of redundant elevator stops. Background Art
[0002] As the number of floors in buildings increases, elevators have become an increasingly important part of people's lives. The greater the distance an elevator travels, the greater its energy consumption and the longer the waiting time for passengers. For schools, hospitals and high-rise buildings, a suitable intelligent elevator parking method is needed to control the operation of the elevator. In addition, it is very important to note that redundant elevator stops cause trouble to passengers. The so-called redundant elevator stops refer to unnecessary elevator stops caused by reasons such as the person who called the elevator giving up the elevator or the lack of space or weight in the elevator making it impossible for people to take the elevator.
[0003] The specific reasons for the redundant elevator stops are: First, insufficient space. If there is an elevator call at any floor, even if the elevator is not fully loaded, the car cannot continue to accommodate new passengers due to insufficient space. The elevator may still stop at the called floor. In this case, the elevator should only stop at the floor required by the passengers in the car. Second, reaching the upper limit of the load. If there is an elevator call at any floor, but its remaining load capacity is far less than the weight of a passenger, the elevator may still stop at the called floor. In this case, the elevator should avoid stopping at this floor. Third, leaving after calling the elevator. The passenger leaves for something after calling the elevator and before the elevator arrives. There is actually no one at the floor, but the elevator will still stop. In this case, the elevator should also avoid stopping at this floor.
[0004] In view of the above-mentioned prior art, it is necessary to reasonably improve the structure of the existing elevator parking system. For this reason, the applicant has made a useful design, and the technical scheme to be introduced below is produced under this background. Utility Model Content
[0005] The task of the utility model is to provide a device for reducing the number of redundant elevator stops, which can reduce unnecessary floor stops during the operation of the elevator, thereby improving the passenger carrying efficiency of the elevator.
[0006] The task of the utility model is accomplished in this way. A device for reducing the number of redundant elevator stops includes a control cabinet and an elevator calling device. The elevator calling device is electrically connected to the control cabinet and is characterized in that: the device also includes a load detection component, an area detection component and a floor detection component electrically connected to the control cabinet. The load detection component is installed on the elevator car to detect the actual weight of the car and send the actual weight of the car to the control cabinet; the area detection component is installed in the elevator car to detect the remaining space in the car; the floor detection component is installed on each floor to detect whether there are people waiting to take the elevator.
[0007] In a specific embodiment of the present utility model, the area detection component uses a car 3D light curtain to detect the actual number of people in the car, and obtains the remaining space in the car by detecting the space occupied by people in the car.
[0008] In another specific embodiment of the present utility model, the floor detection component includes a gravity sensor and a floor station camera.
[0009] In yet another specific embodiment of the present invention, the gravity sensor is disposed under the floor.
[0010] In yet another specific embodiment of the present invention, a plurality of gravity sensors are provided.
[0011] In another specific embodiment of the present utility model, the gravity sensor is arranged in a rectangular area a with a length of 2.5 meters and a width of 1.4 meters near the landing door.
[0012] In a further specific embodiment of the present invention, the rectangular area a is symmetrical with respect to the center line c of the landing door.
[0013] In a more specific embodiment of the present invention, the long side of the rectangular area a is 0.3 meters away from the wall where the elevator calling device is located.
[0014] In yet another specific embodiment of the present invention, the floor station camera is responsible for 3D detection of the core area protection range and the pedestrian trend range outside the car door. The core area protection range is the range at the floor door entrance, and the pedestrian trend range outside the car door is the range of 2.5m away from the floor door.
[0015] The utility model has the beneficial effect that the load detection component and the area detection component in the device detect the actual weight of the car and the remaining space in the car respectively. If any one of the actual weight of the car and the remaining space fails to meet the requirement of accommodating new passengers, the elevator will not stop even if there is an elevator call instruction on the floor. If both meet the requirement of accommodating new passengers, the floor detection component in the device is used to detect whether there are passengers on the floor, so as to decide whether to stop at the floor. The device effectively controls the parking of the elevator, improves the passenger carrying efficiency of the elevator, solves the problem of redundant elevator stops, has the effect of energy saving and consumption reduction, reduces the anxiety of passengers taking the elevator, and improves the comfort of passengers taking the elevator.

[0021] The specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings, but the description of the embodiments is not a limitation of the technical solution. Any changes in form rather than substance based on the concept of the present invention should be regarded as the protection scope of the present invention.
[0022] In the following description, all concepts related to directionality or orientation such as up, down, left, right, front and back are based on the positions shown in the corresponding drawings, and therefore cannot be understood as a special limitation on the technical solution provided by the utility model.
[0023] See also Figure 1 The utility model relates to a device for reducing the number of redundant elevator stops, including a control cabinet 1, an elevator calling device 2, a load detection component 3, an area detection component 4 and a floor detection component 5, wherein the elevator calling device 2, the load detection component 3, the area detection component 4 and the floor detection component 5 are all electrically connected to the control cabinet 1.
[0024] The load detection component 3 is installed on the elevator car 6, and is used to detect the actual weight of the car 6 and send the actual weight of the car 6 to the control cabinet 1. The control cabinet 1 calculates the maximum weight of a new passenger that can be accommodated. If there is not enough capacity, for example, the minimum weight of a passenger is set to 20kg, and the maximum weight of a new passenger that can be accommodated is less than the minimum weight of a passenger, then the elevator will enter the direct operation mode, and will not stop at any floor where there is no instruction from the car along the way, even if there is a floor call from outside the elevator.
[0025] The area detection component 4 is installed in the elevator car 6, and the remaining space in the car 6 is obtained by detecting the space occupied by people in the car 6. Specifically, the car 3D light curtain is used to obtain human body data by analyzing the image. The human body data includes: the number of people N, the height of the human body H and the width of the human body shoulders D. The volume of all people in the car 6 is calculated by analyzing the human body data, and then the remaining space in the car 6 is calculated. The remaining space in the car 6 is sent to the control cabinet 1, and the control cabinet 1 calculates the maximum space that can accommodate new passengers. Assuming that the space occupied by each passenger is approximately calculated to be 1200cm, if there is not enough space to accommodate new passengers, the elevator will enter the direct operation mode, and will not stop for floors without instructions in the car along the way, even if there is a floor call, it will not stop.
[0026] The floor detection component 5 is installed on each floor to detect whether there are people waiting to take the elevator, and specifically includes a gravity sensor 51 and a landing camera 52. The gravity sensor 51 is set under the floor. There are multiple gravity sensors 51 and they are evenly distributed near the floor door 7 to measure whether there are people or goods on the floor. Specifically, Figure 2 As shown, the gravity sensor 51 is arranged within a rectangular area a with a length of 2.5 meters and a width of 1.4 meters near the floor door 7. Furthermore, the rectangular area a is symmetrical relative to the center line c of the floor door. Furthermore, the long side of the rectangular area a is 0.3 meters away from the wall where the elevator calling device 2 is located.
[0027] The landing camera 52 is mainly responsible for the 3D detection of the core area protection range and the pedestrian trend range outside the car door. The core area protection range is the range at the entrance of the landing door 7, that is, Figure 3 The area b in the figure is the threshold for entering the door. The pedestrian trend range outside the car door is the range of 2.5m from the landing door 7, that is, Figure 3 The d area in the figure is the waiting area. It is used to determine whether there are passengers in this area.
[0028] When the elevator is running, if the car 6 can respond to the call outside the hall, the floor detection component 5 works, and the control cabinet 1 activates the landing camera 52 to send a plane image of the floor waiting area to the control cabinet 1.
[0029] Please continue reading Figure 4 Combined with Figures 1 to 3 The working process of the device for reducing the number of redundant elevator stops described in the utility model is:
[0030] S1) A passenger presses the elevator call device 2 on the first floor, and the elevator call device 2 sends the elevator call signal to the control cabinet 1;
[0031] S2) The load detection component 3 detects the actual weight of the current elevator car 6 in real time and sends it to the control cabinet 1, and the area detection component 4 calculates the remaining space in the car 6 in real time and sends it to the control cabinet 1;
[0032] S3) The control cabinet 1 calculates the maximum weight of the new passenger according to the actual weight of the current car 6, and determines whether the maximum weight of the new passenger that can be accommodated is greater than the minimum weight of a passenger. If so, execute step S4); if not, execute step S8);
[0033] S4) The control cabinet 1 determines whether the remaining space in the car 6 is greater than the minimum space for one passenger. If so, execute step S5); if not, execute step S8);
[0034] S5) The timing component calculates the time required for the car 6 to reach the elevator calling floor in real time, and the control cabinet 1 determines whether the required time is greater than the set value. If so, step S6 is executed; if not, step S8 is executed);
[0035] S6) The floor detection component 5 at the elevator calling floor detects whether there are people waiting to take the elevator. If yes, execute step S7); if not, execute step S8);
[0036] S7) the control cabinet 1 controls the elevator car 6 to stop at the elevator calling floor;
[0037] S8) The control cabinet 1 cancels the elevator call command for the elevator car 6 to stop at the elevator calling floor.
[0038] The order of step S3) and step S4) can be swapped. Step S5) is a conventional setting in the prior art, and the set value is the time required for the car 6 to decelerate from the elevator speed to stop.
