[0028] Further features and advantages of the present invention will become apparent from the following detailed description of exemplary embodiments of the present invention with reference to the attached drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0034] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0035] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0036] See also Figure 1The present invention discloses an elevator control system, which is arranged in a building. In this embodiment, the building is provided with two entrances and two elevators, including elevator No. 1 and elevator No. 2 in this embodiment, and the two elevators are located at different locations in the building and the distance between the two elevators is relatively far.

[0037] The elevator control system includes an elevator controller, an elevator call switch, a display, a pre-call switch and a data analysis and processing module.

[0038] Each elevator is equipped with an elevator controller, which is used to control the operation of the elevator. At the entrance floor of the building, each elevator door is equipped with a call switch, which is connected to the elevator controller by electrical signals. The call switch is used to call the elevator, including an up button and a down button (in some embodiments, the down button is not provided, for example, the down button is not provided on the first floor without a basement).

[0039] The pre-call switch is installed at the building entrance and is connected to the elevator controller of elevator No. 1 and elevator No. 2 by electrical signals, respectively, to pre-call elevator No. 1 and elevator No. 2 separately or simultaneously. The pre-call switch installed at the building entrance can realize the remote pre-call operation of the elevator, that is, after the passenger presses the pre-call switch at the building entrance, the elevator controller of the called elevator receives the down command. When the passenger walks to the corresponding elevator entrance, the elevator has arrived at the passenger's floor or is moving towards the passenger's floor, thereby reducing the time passengers wait for the elevator and improving the efficiency of taking the elevator.

[0040] The data analysis and processing module is connected to the multiple elevator controllers by electrical signals. The data analysis and processing module calculates the waiting time of the elevators according to the data transmitted by the elevator controllers, and plans the optimal elevator plan in combination with the operating status of the elevators. A display is installed at each of the two entrances of the building. The display is connected to the data analysis and processing module by electrical signals to display the operating status of elevator No. 1 and elevator No. 2 and the estimated waiting time for elevator No. 1 and elevator No. 2 to arrive at the floor where the building entrance is located, and to display the optimal elevator plan.

[0041] An access control switch is also provided at the entrance of the building, and the access control switch is electrically connected to the data analysis and processing module; the data analysis and processing module plans the optimal elevator plan based on the identified personnel information, and calls the elevator corresponding to the optimal elevator plan. This setting can simplify the operation steps of passengers. The passenger completes the elevator pre-call at the same time as swiping the access control card, eliminating the process of pressing the pre-call switch. In some embodiments, the access control switch is provided with a face recognition module, and the elevator corresponding to the last elevator plan is automatically called after the face recognition is successful.

[0042] Further, the data analysis and processing module calculates the waiting time of the elevator according to the data transmitted by the elevator controller, and plans the optimal elevator plan in combination with the operating state of the elevator. The data analysis and processing module plans the optimal elevator plan according to the waiting time of the elevator, the operating state of the elevator and the distance between the elevator and the entrance. Among them, the operating state of the elevator includes the remaining space in the elevator, the number of people in the elevator, the number of people waiting to get on the elevator at the target floor, and the actual load of the elevator. It can be seen that the waiting time of the elevator, the operating state of the elevator and the distance between the elevator and the entrance are all factors affecting the optimal elevator plan, among which the waiting time of the elevator is the main factor affecting the optimal elevator plan. Calculating the waiting time of the elevator includes: calculating the waiting time of the elevator according to the number of floors the elevator is about to reach, the number of people in the elevator and the opening and closing time of the elevator. Specifically, the number of floors the elevator is about to reach includes the number of floors where the elevator stops for passengers and the number of floors where the elevator stops for passengers. The more floors the elevator stops, the lower the efficiency of the elevator operation; the more people the elevator takes, the more time it takes to get on and off, and the lower the operating efficiency of the elevator. Furthermore, the data analysis and processing module delays calling the elevator corresponding to the optimal elevator plan after receiving the personnel information for a preset time. Assume that the time required to reach the elevator corresponding to the optimal elevator plan from the building entrance is T1; the time for the elevator corresponding to the optimal elevator plan to reach the floor where the passenger is located is T2; the preset time is equal to T1 minus T2. If T1 is less than or equal to T2, the data analysis and processing module calls the elevator immediately. Of course, in some embodiments, the preset time can be a fixed time, and the setting of the fixed time does not have to be associated with T1 and T2.

[0043] In some embodiments, a building may include multiple underground spaces. When calling an elevator from the first floor, the elevator may go down from the upper floor to the first floor, or it may go up from the negative floor to the first floor. When the elevator goes up from the negative floor to the first floor, the remaining space in the elevator, the number of people in the elevator, the number of people waiting to get on the elevator on the target floor, and the actual load of the elevator will have a greater impact on the passengers on the floor where the building entrance is located. Among them, the impact of the remaining space in the elevator is mainly: by setting a camera in the elevator car, through conventional visual recognition and calculation schemes, determine the remaining space in the elevator. If the remaining space is sufficient, the elevator is recommended as a candidate elevator. If the remaining space in the elevator is insufficient, the elevator is not recommended as a candidate elevator. This is mainly because everyone's body shape, weight, and carrying items are the same. Even if the elevator is not overweight, there may be insufficient space for passengers. Therefore, this indicator is used as one of the indicators for determining whether the elevator is a candidate elevator. The impact of the number of people in the elevator is mainly: to prevent the elevator from being overcrowded. Each elevator has a specified number of passengers. Once the elevator is overcrowded, it will bring different degrees of safety hazards. The number of passengers in the elevator is also identified by the camera installed in the car. The impact of the number of people waiting to get on the elevator at the target floor is mainly: when there are too many people waiting at the elevator door, passengers may need to queue up when they arrive at the elevator door and cannot enter the elevator in the first wave. They may need to wait for the elevator to complete a transport and return before they can enter the elevator, which affects the efficiency of taking the elevator. The impact of the actual load of the elevator is mainly: when it is overcrowded, even if there is still space in the elevator, new passengers cannot enter. In summary, the data analysis and processing module comprehensively plans the elevator plan for passengers based on the above-mentioned influencing factors, which can greatly improve the efficiency of passengers taking the elevator.

[0044] The access control switch is electrically connected to the data analysis and processing module; the data analysis and processing module plans the optimal elevator plan based on the identified personnel information, and calls the elevator corresponding to the optimal elevator plan, specifically including: after unlocking the access control switch by swiping a card or face, the elevator is not called immediately, and the call is delayed for about 5 seconds (or 10 seconds or other preset time). If multiple people call the same floor, it is recommended that multiple people take the same elevator to improve the utilization rate of the elevator. Of course, when making recommendations, the elevator's overcrowding and overweight situations must also be considered to prevent overcrowding and overweight incidents.

[0045] In some embodiments, the display can show the remaining arrival time of the elevator after the call. The remaining arrival time is equal to the remaining time to go to the floor plus the waiting time for passengers to enter and exit after the elevator stops plus the time for the elevator to open and close the door. An approximate fuzzy time is calculated to help users determine which elevator to take.

[0046] Furthermore, the elevator control system also includes an elevator call APP, which can view the estimated waiting time of each elevator in real time and call the elevator remotely through wireless data transmission. The elevator status can be viewed on a mobile phone with the elevator call APP installed, and the optimal elevator can be selected according to the elevator operation status to achieve diversion. For example, the elevator call APP shows that there are 8 people waiting to get on the elevator at the target floor of the No. 1 elevator, and there are 20 seconds to reach the target floor; there are 2 people waiting to get on the elevator at the target floor of the No. 2 elevator, and there are 30 seconds to reach the target floor; passengers can choose the elevator to take in a targeted manner according to the above APP prompts; for example, the passenger has to carry some large items while taking the elevator. At this time, although the waiting time of the No. 1 elevator is shorter, there are too many passengers waiting for the No. 1 elevator. In order to avoid occupying too much elevator space, passengers carrying large items can choose to take the No. 2 elevator with fewer people waiting. Because the No. 1 elevator and the No. 2 elevator are located in different locations, and the distances from the No. 1 door and the No. 2 door are also different, at this time, the passenger can choose to enter the building from the No. 1 door or the No. 2 door according to the APP prompts, and quickly reach the location of the No. 2 elevator. It should be noted that the number of people waiting to get on the elevator at the designated floor can be determined by installing a camera at the elevator entrance and performing visual recognition.

[0047] The elevator status section of the display lists all the floors that the elevator is going to. If there is no floor to go to, it will be displayed as idle. In the case of multiple elevators, users can also manually select the elevator they want to take. The method of manually selecting the elevator to take includes making an elevator reservation through a mobile phone APP. The method of manually selecting the elevator to take also includes setting up a call panel at the entrance of the building, and you can select the elevator to call at the door.

[0048] It should be noted that the elevators in this system can be set to any number greater than or equal to 2, and the number of building entrances can be 1 or other values ​​greater than 2.

[0049] In summary, the elevator control system data analysis and processing module provided by the present invention is respectively connected to multiple elevator controllers by electrical signals, calculates the waiting time of the elevator according to the data transmitted by the elevator controller, and plans the optimal elevator plan in combination with the operating status of the elevator; the display is installed at the building entrance and is electrically connected to the data analysis and processing module, which is used to display the operating status and estimated waiting time of the elevator, and display the optimal elevator plan. After arriving at the building entrance, the passengers can use the pre-call switch installed at the building entrance to call the optimal elevator in advance according to the optimal elevator plan on the display. When the passengers walk from the building entrance to the elevator, the elevator moves to the floor where the building entrance is located, reducing the waiting time of the passengers and improving the operating efficiency of the elevator.
