Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 5, the intelligent elevator system of the embodiment includes a controller (not shown) and a plurality of elevators, wherein each elevator includes a car 1 installed in an elevator shaft 100, and landing doors 2 and buttons (not shown) disposed in elevator halls 200 of each floor, the buttons are in communication connection with the controller for controlling the operation of the elevator, an image collector (not shown) is further disposed in the elevator halls 200 of each floor, the image collector is used for collecting image information of the elevator halls 200 and calculating the number of passengers in the elevator halls, and the image collector is in communication connection with the controller; a load cell (not shown) is arranged on the car 1 and used for weighing the load in the car 1, and the load cell is in communication connection with the controller; still dispose display device 3 on the layer door 2, display device 3 with controller communication connection, display device 3 is used for showing the corresponding remaining passenger number of carrying of car 1.
Specifically, the intelligent elevator system of the embodiment is configured with an image collector in each floor of the elevator car 200, and the image collector can collect images of the floor of the elevator car 200 and calculate the number of people in the floor of the elevator car 200 by using an image recognition technology. The image collector generally includes a camera for collecting image information and an image processor for identifying the collected images and calculating the number of people on the elevator by using an image identification technology. The method for image recognition by the image processor may adopt an algorithm for face recognition or other human body recognition in the prior art, which is not limited herein. The image collector sends the information of the number of passengers in the corresponding elevator room 200 to the controller, and meanwhile, the controller can receive load information fed back by the weighing sensors in the elevator cars 1. Since the load capacity of the car 1 is set, the number of passengers that can be continuously increased corresponding to the car 1 can be calculated according to the load information fed back by the load cell, and the remaining number of passengers in the car 1 can be calculated. The controller can comprehensively analyze the number of passengers taking the elevator room 200 on different floors and the information of the number of remaining passengers carrying the elevator cars 1 to work out the optimal operation mode of each elevator car 1, so that the requirement of improving the carrying efficiency is met, and the energy consumption can be reduced. In addition, because the image collector is arranged, the image collector is utilized to identify the image of the elevator room to identify the face of the elevator, and the face of the elevator can be networked with a public security system to track and identify illegal personnel; the priority can also be set through face recognition, the VIP user is preferentially received, and the elevator room 200 of the floor where the VIP user is located is stopped.
The specific control method comprises the following steps: after the button of the elevator room is pressed, the image collector in the elevator room 200 collects the image information of the elevator room and calculates the number of passengers taking the elevator room 200, meanwhile, the controller calculates the remaining number of passengers carrying the elevator car according to the heavy load information fed back by the weighing sensor in each elevator car 1, and the controller controls one or more corresponding elevators to move to the elevator room 200 according to the number of passengers taking the elevator room 200 and the calculated remaining number of passengers carrying the elevator car; at the same time, the display device 3 on the middle door 2 of the elevator car 200 displays the remaining number of passengers in the corresponding car 1. Specifically, after a user who wants to take the elevator in the elevator room 200 of a certain floor presses a button, the image collector collects image information in the elevator room 200 to calculate and obtain the number of people taking the elevator, meanwhile, the controller simultaneously obtains the number of remaining passengers in each car 1 in operation, and the controller controls one or more cars 1 to run and stop to the elevator room 200 so as to meet the elevator taking requirements of the user in the elevator room 200. In the actual use process, the elevator runs in an up-going process and a down-going process, and in the up-going process of the elevator, the highest position finally reached by the car 1 is not necessarily the highest floor because the floors where users are located are different; however, in the descending process of the elevator, the user usually moves to the lowest floor (the ground upper floor or the underground garage) by taking the elevator, and the car 1 finally runs to the lowest floor, so how to better control the descending process of the elevator is very important for improving the carrying efficiency and reducing the energy consumption. Often during off-duty periods the usage of the elevator is higher and the car 1 will eventually run to the lowest floor.
At this time, after the down button of a certain elevator car 200 is pressed, the image collector in the elevator car collects the image information of the elevator car and calculates the number of passengers n0 in the elevator car, and the controller calculates the number of remaining passengers n1 of all the cars 1 which are located above the elevator car and run downwards;
if n1 is not less than n0, all cars 1 that are located above the elevator car 200 and traveling downward travel with the least number of door openings. Specifically, if the total number of remaining passengers n1 of all the cars 1 traveling downward above the elevator hall 200 is not less than n0, it is described that the cars 1 traveling downward can satisfy the boarding request of the user in the elevator hall 200, and in this case, the cars 1 are operated so as to have the smallest number of door openings in order to satisfy the reduction of energy consumption. For example: three passengers need to take the elevator to go down in the elevator room 200 of the five-floor, three cars 1 run downwards above the elevator room 200 of the five-floor, wherein the number of remaining passengers in one car 1 is two, the number of remaining passengers in one car 1 is five, and the number of remaining passengers in one car 1 is one, the cars 1 with the number of remaining passengers being five are controlled to stop at the elevator room 200, and the remaining two cars 1 do not stop at the elevator room 200. Therefore, the number of times of starting and stopping the elevator can be reduced, energy consumption is reduced, and meanwhile, the carrying efficiency of the elevator can be improved without stopping the car 1.
If n1 is less than n0, all cars above the cab that are traveling downward are traveling to the cab landing; meanwhile, the controller calculates the number n2 of remaining passengers of the car located immediately below the elevator car, and calculates the distances L1 and L2 between the car and the elevator car at the bottom; if n2 is not less than the difference between n0 and n1 and L1 is not greater than L2, the car immediately below the car moves in reverse upward direction until the car stops, and then continues downward movement. Specifically, if the total number of remaining passengers n1 in the total of all the cars 1 traveling downward above the elevator hall 200 is less than n0, it means that the cars 1 traveling downward cannot meet the boarding request of the user in the elevator hall 200. At this time, all the cars 1 moving downwards above the elevator car 200 are firstly controlled to stop at the elevator car 200, so as to meet the elevator taking requirements of part of users, and meanwhile, the carrying efficiency is improved and the energy consumption is reduced. Then, in order to more effectively improve the carrying efficiency and optimize the user experience, the controller determines the remaining number of passengers n2 of the car 1 immediately below the elevator car 200 and analyzes the position of the car 1. If the car 1 immediately below the elevator car 200 can meet the elevator taking requirements of the rest of users, and meanwhile, the car 1 is closer to the elevator car 200, the car 1 is controlled to move upwards in the reverse direction and stop at the elevator car 200, and then the car continues to move downwards again. For example: six passengers need to take the elevator and go down in the elevator room 200 of the fifth floor, two cars 1 are arranged above the elevator room 200 of the fifth floor and move downwards, wherein the number of the remaining passengers in one car 1 is two, and the number of the remaining passengers in the other car 1 is three, so that the two cars 1 above the elevator room 200 of the fifth floor can carry the five passengers after stopping, at the moment, the number of the remaining passengers in the cars 1 which move downwards at the position of the fourth floor is three, and the cars 1 at the position of the fourth floor go upwards in the opposite direction and stop at the elevator room 200 of the fifth floor, so that the remaining passengers can take the elevator as soon as possible. Therefore, on one hand, the carrying capacity of the car 1 can be fully utilized to improve the carrying efficiency, and on the other hand, the waiting time of a user can be greatly reduced to improve the user experience; moreover, the occurrence of the condition that the car 1 runs in no load or half load can be effectively reduced, the running stroke of the whole car 1 is fully reduced, and the energy consumption is reduced.
Preferably, in the process of controlling the operation of each elevator by the controller, in order to provide better experience for users, the controller can estimate the stopping time of the elevator in the corresponding elevator hall 200 according to the operation state of each elevator, specifically: when a user presses a button in the elevator car 200 of a floor, the controller calculates the time required for the car 1 to travel to the elevator car 200 again according to the traveling state of the corresponding car 1, and displays the time on the display device 3. The controller stores the average time T1 required by the car 1 to circularly run up and down once, the controller stores the average time T2 required by the car 1 to stop once, and the controller also stores the time T3 required by the car 1 to move between the adjacent two floors of elevator rooms 200. The above-mentioned times are all estimated times.
The specific calculation process is as follows:
in the first scenario, after the user presses the button, the running direction of the corresponding car 1 is the same as the direction indicated by the button, and if the car 1 moves towards the elevator car 200 at the floor, the estimated time of arriving at the elevator car 200 is calculated according to the required stopping times of the car 1 before running to the elevator car 200, and is displayed through the display device 3. Specifically, the estimated time required for the car 1 to travel to the elevator car 200 can be estimated based on the number of stops multiplied by T2, and the number of floors that the car 1 needs to travel to the elevator car 200 is multiplied by T3.
And in a second scenario, after the user presses the button, the running direction of the corresponding car 1 is the same as the direction indicated by the button, and if the car 1 moves away from the elevator hall 200 of the floor, the controller calculates the estimated time for the car 1 to reach the elevator hall 200 according to the height position of the elevator hall 200. Specifically, since the car 1 is driven away from the car 200, the car 1 usually needs to complete a complete ascending or descending movement when moving to the car 200 again, in this case, the estimated time is further estimated according to the height position of the car 200, that is, along the running direction of the car 1, if the car 200 is at the first half-stroke position of the car 1, the estimated time is 0.5T 1; if the car 200 is in the rear half travel position of the car 1, the estimated time is T1. For example, for a 10-story building, the user presses a down button on the elevator car 200 of the 8-story building, and at this time, the estimated time is 0.5T1 when the car 200 moves down to the 5-story building; similarly, when the user presses the down button on the 4 th elevator car 200, and the car 200 moves down to the 2 nd floor, the estimated time is T1.
And in a third scenario, after the user presses the button, the running direction of the corresponding car 1 is opposite to the direction indicated by the button, and if the car 1 moves towards the elevator car 200 at the floor, the controller calculates the estimated time for the car 1 to reach the elevator car 200 according to the height position of the elevator car 200. Specifically, since the car 1 moves toward the elevator car 200 and is opposite to the boarding direction of the user, in this case, the estimated time is further estimated according to the height position of the elevator car 200, that is, along the moving direction of the car 1, if the elevator car 200 is at the first half-stroke position of the car 1, the estimated time is T1 long; if the car 200 is in the rear half travel position of the car 1, the estimated time is 0.5T 1. For example, for a 10-floor, the user presses the down button in the elevator car 200 of the 8-floor, and at this time, the estimated time is 0.5T1 when the car 200 moves upward to the 5-floor; similarly, when the user presses the down button on the elevator car 200 at floor 4, and the car 200 moves up to floor 2, the estimated time is T1.
And in the fourth scenario, after the user presses the button, the running direction of the corresponding car 1 is opposite to the direction indicated by the button, and if the car 1 moves away from the elevator hall 200 of the floor, the controller calculates the estimated time for the car 1 to reach the elevator hall 200 according to the height position of the elevator hall 200. Specifically, since the car 1 is driven away from the elevator car 200 and runs in the direction opposite to the boarding direction of the user, in this case, the estimated time is further estimated according to the height position of the elevator car 200, that is, along the running direction of the car 1, if the elevator car 200 is at the first half-stroke position of the car 1, the estimated time is T1; if the car 200 is in the rear half travel position of the car 1, the estimated time is 0.5T 1.
