Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and more particularly to an energy-saving control method and system based on elevators. Background Art

[0002] In modern society, elevators, as indispensable vertical transportation tools within buildings, are widely used in various locations, such as office buildings, shopping malls, and residential communities. With the acceleration of urbanization and the continuous increase in building height, the number and frequency of elevator use are also increasing. However, traditional elevator operation and control methods have gradually exposed many problems and are unable to meet the current demand for efficiency, energy saving, and intelligence. Most traditional elevators adopt a fixed operating mode, running sequentially according to a preset floor stop sequence or responding to simple call signals. This operation method lacks accurate perception and analysis of actual passenger flow and distribution, resulting in unnecessary stops and empty runs in many cases, which leads to significant energy waste. In addition, elevators consume a lot of electricity during starting and braking, and the frequent starts and stops under traditional control methods further exacerbate energy consumption. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the present invention aims to provide an energy-saving control method and system based on an elevator.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] An energy-saving control method based on an elevator, the method comprising the following steps:

[0006] S1, associate at least two elevators in the same building that can reach the same floor and mark them as associated elevators;

[0007] S2, obtaining the status information of passengers waiting for the elevator at each associated elevator on each elevator stop floor, and obtaining the status information of each associated elevator in operation;

[0008] The status information of the passengers waiting for the elevator includes the passengers' intention to take the elevator, the floor where the passengers are waiting for the elevator, and the number of passengers waiting for the elevator; the status information of the associated elevator during operation includes the number of passengers already carried in the associated elevator during operation, the number of passengers accommodated when the associated elevator is fully loaded, the carrying intention information of the passengers in the associated elevator during operation, and the operating trend information of the associated elevator;

[0009] S3, processing and analyzing the number of people already carried by the associated elevator during operation, the number of people that the associated elevator can accommodate when fully loaded, the carrying intention information of the passengers in the associated elevator during operation, and the floor information of the passengers waiting for the elevator to obtain the carrying status of the associated elevator;

[0010] S4, if the load condition of the associated elevator meets the requirements, the operation trajectory energy-saving path instruction is generated based on the operation trend information of the associated elevator, the intention information of the passengers waiting for the elevator, the floor information of the passengers waiting for the elevator, and the number of passengers waiting for the elevator;

[0011] S5, controlling the operation of the associated elevator according to the energy-saving path instruction of the running trajectory, and reminding the elevator waiting person to wait in the corresponding elevator area on the floor.

[0012] Preferably, the carrying intention information of the internal passengers when the associated elevator is running is specifically the arrival floor information designated by the internal passengers when the associated elevator is running;

[0013] The operation trend information of the associated elevator is specifically that the associated elevator runs from top to bottom toward the floor where the passengers are waiting for the elevator, or the associated elevator runs from bottom to top toward the floor where the passengers are waiting for the elevator.

[0014] Preferably, the method further comprises the following steps:

[0015] Divide the floor areas of the building that can be reached by the associated elevator into an elevator waiting area and an elevator going area, count the number of people waiting for the elevator in the elevator waiting area and mark them as the first waiting number;

[0016] Obtain the walking speed information of each passenger in the area to which the elevator is heading, and the distance between each passenger and the elevator room. Calculate the time it takes for each passenger in the area to which the elevator is heading to move to the elevator room based on the walking speed information and the distance between each passenger and the elevator room.

[0017] Obtain the vertical distance between the location of the associated elevator and the floor where the passengers are waiting for the elevator, and the speed information of the associated elevator during operation, and calculate the time it takes for the associated elevator to run to the floor based on the speed information and the vertical distance value of the associated elevator during operation;

[0018] Count the total number of passengers on the floor whose time for each passenger to move to the elevator room is less than or equal to the time for the associated elevator to reach the floor, and mark them as the second waiting number;

[0019] The first number of people waiting and the second number of people waiting are cumulatively calculated to obtain the number of people waiting to take the elevator.

[0020] Preferably, step S3 specifically includes:

[0021] The number of passengers in the associated elevator that has changed when the associated elevator arrives at the floor where the passengers are waiting is obtained according to the information of the floor where the passengers are waiting and the carrying intention information of the passengers in the associated elevator when the elevator is running;

[0022] The actual number of passengers carried in the associated elevator is calculated by calculating the change in the number of passengers carried in the associated elevator when the associated elevator arrives at the floor where the passengers are waiting for the elevator and the number of passengers carried in the associated elevator during operation;

[0023] If the actual number of people carried in the associated elevator is less than the number of people that the associated elevator can accommodate when fully loaded, the carrying conditions of the associated elevator meet the requirements.

[0024] Preferably, step S4 specifically includes:

[0025] The number of passengers that the associated elevator can accommodate when fully loaded and the actual number of passengers inside the associated elevator are calculated to obtain the actual remaining number of passengers that can be accommodated inside the associated elevator;

[0026] The operation trend information of the elevator, the intention information of the passengers waiting for the elevator, the actual number of passengers remaining in the elevator and the number of passengers waiting for the elevator are processed to generate an energy-saving path instruction for the operation trajectory.

[0027] The operation trend information of the elevator, the intention information of the passengers waiting for the elevator, the actual number of passengers remaining in the elevator and the number of passengers waiting for the elevator are processed to generate the operation trajectory energy-saving path instruction, which specifically includes the following steps:

[0028] Determine whether the associated elevator needs to stop when passing the floor where the passenger is waiting for the elevator based on the operating trend information of the associated elevator and the passenger's intention to take the elevator;

[0029] When it is determined that the associated elevator needs to stop at the floor where the passengers are waiting, the actual remaining number of passengers inside the associated elevator is compared with the number of passengers waiting to be loaded, and then the first execution trajectory path instruction, the second execution trajectory path instruction, the third execution trajectory path instruction, the fourth execution trajectory path instruction, and the fifth execution trajectory path instruction are generated.

[0030] Preferably, judging whether the associated elevator needs to stop when passing the floor where the waiting passenger is located based on the running trend information of the associated elevator and the passenger's intention information of the elevator, specifically includes the following steps:

[0031] If the running direction information of the associated elevator is consistent with the direction of the elevator intention information of the elevator waiting person, it is determined that the associated elevator needs to stop when passing the floor where the elevator waiting person is located;

[0032] If the running direction information of the associated elevator is inconsistent with the direction of the elevator waiting person's intention to take the elevator, the carrying intention information of the passengers inside the associated elevator during operation and the floor information of the waiting passengers are processed and analyzed to determine whether the associated elevator needs to stop when passing the floor where the waiting passengers are.

[0033] Preferably, after processing and analyzing the carrying intention information of the internal passengers and the floor information of the passengers waiting for the elevator when the associated elevator is running, it is determined whether the associated elevator needs to stop when passing the floor where the passengers are waiting for the elevator, which specifically includes the following steps:

[0034] If the carrying intention information of the passengers inside the associated elevator is consistent with the floor information of the passengers waiting for the elevator, the associated elevator is determined to need to stop when passing the floor where the passengers are waiting for the elevator, and the number of passengers waiting on the floor where the passengers are waiting for the elevator is compared with the actual number of passengers remaining in the associated elevator, and the corresponding number of passengers waiting for the elevator is reminded to move to the associated elevator;

[0035] If the carrying intention information of the internal carrier of the associated elevator is inconsistent with the floor information of the person waiting for the elevator when the associated elevator is running, it is determined that the associated elevator does not need to stop when passing the floor where the person waiting for the elevator is.

[0036] Preferably, when it is determined that the associated elevator needs to stop at the floor where the passengers are waiting, the actual number of passengers remaining in the associated elevator is compared with the number of passengers waiting for the elevator, and then an energy-saving path instruction for the running trajectory is generated, which specifically includes the following steps:

[0037] If there is at least one associated elevator whose actual remaining capacity is greater than or equal to the number of passengers waiting for the elevator, then one of the associated elevators whose actual remaining capacity is greater than or equal to the number of passengers waiting for the elevator is marked as the first execution associated elevator, and the remaining associated elevators are marked as the second execution associated elevators, and a first execution trajectory path instruction is generated for the first execution associated elevator, and a second execution trajectory path instruction is generated for the second execution associated elevator;

[0038] If the number of people actually remaining in each associated elevator is less than the number of people waiting to take the elevator, compare the total number of people actually remaining in all associated elevators with the number of people waiting to take the elevator;

[0039] If the sum of the actual remaining number of people that can be loaded in all associated elevators is greater than the number of people waiting for the elevators, then the associated elevator with the largest actual remaining number of people that can accommodate the number of people waiting for the elevators is marked as the third execution associated elevator, and the remaining associated elevators are marked as the fourth execution associated elevators. A third execution trajectory path instruction is generated for the third execution associated elevator, and a fourth execution trajectory path instruction is generated for the fourth execution associated elevator.

[0040] If the total number of people actually remaining in all associated elevators is equal to or less than the number of people waiting to board the elevators, all associated elevators are marked as fifth execution associated elevators, and a fifth execution trajectory path instruction is generated for the fifth execution associated elevators;

[0041] Among them, the first execution trajectory path instruction, the second execution trajectory path instruction, the third execution trajectory path instruction, the fourth execution trajectory path instruction, and the fifth execution trajectory path instruction are combined to form an operation trajectory energy-saving path instruction.

[0042] Preferably, controlling the operation of the associated elevator according to the running trajectory energy-saving path instruction specifically includes the following steps:

[0043] The first execution trajectory path instruction controls the first execution associated elevator to stop at the floor where the waiting passenger is located, and the second execution trajectory path instruction controls the second execution associated elevator not to stop at the floor where the waiting passenger is located;

[0044] The third execution trajectory path instruction controls the third execution associated elevator to stop at the floor where the passenger is waiting, and the fourth execution trajectory path instruction controls the fourth execution associated elevator not to stop at the floor where the passenger is waiting;

[0045] The fifth execution trajectory path instruction controls the fifth execution associated elevator to stop at the floor where the passengers are waiting.

[0046] An energy-saving control system based on an elevator, further comprising:

[0047] a marking module, which associates at least two elevators in the same building that can reach the same floor and marks them as associated elevators;

[0048] An acquisition module is used to obtain the status information of passengers waiting for the elevator at each associated elevator on each floor where the elevator stops, and to obtain the status information of each associated elevator during operation;

[0049] The status information of the passengers waiting for the elevator includes the passengers' intention to take the elevator, the floor where the passengers are waiting for the elevator, and the number of passengers waiting for the elevator; the status information of the associated elevator during operation includes the number of passengers already carried in the associated elevator during operation, the number of passengers accommodated when the associated elevator is fully loaded, the carrying intention information of the passengers in the associated elevator during operation, and the operating trend information of the associated elevator;

[0050] The processing and analysis module processes and analyzes the number of people already carried in the associated elevator during operation, the number of people that the associated elevator can accommodate when fully loaded, the carrying intention information of the people carried in the associated elevator during operation, and the floor information of the people waiting for the elevator to obtain the carrying status of the associated elevator;

[0051] The instruction generation module, if the carrying conditions of the associated elevator meet the requirements, generates an energy-saving path instruction based on the operation trend information of the associated elevator, the intention information of the passengers waiting for the elevator, the floor information of the passengers waiting for the elevator, and the number of passengers waiting for the elevator;

[0052] The control reminder module controls the operation of the associated elevator according to the energy-saving path instructions of the running trajectory, and reminds the people waiting for the elevator to wait in the corresponding elevator area on their floor.

[0053] Compared with the prior art, the present invention has the following beneficial effects:

[0054] This application processes and analyzes the operating trend information of the associated elevators, the elevator-riding intention information of the elevator waiting passengers, the floor information of the waiting elevator passengers, and the number of waiting elevator passengers to generate an energy-saving path instruction for the operating trajectory. By generating the energy-saving path instruction for the operating trajectory, the operating trajectory of the associated elevators can be optimized and controlled, thereby avoiding invalid stops and empty runs of the elevators, enabling the elevators to serve the elevator waiting passengers more efficiently and reducing unnecessary energy consumption. This application realizes the operation management of the associated elevators, thereby achieving the purpose of energy saving. At the same time, this application can remind the elevator waiting passengers to wait in the corresponding elevator area on their floor, thereby improving the elevator riding efficiency of the elevator waiting passengers and indirectly reducing the energy waste caused by the disorderly waiting of the elevator waiting passengers. Therefore, the elevator waiting passengers can quickly find the corresponding elevator area to wait, thereby avoiding the elevator staying at a certain floor for a long time waiting for the elevator waiting passengers, thereby reducing energy consumption.

[0056] Figure 2 The present invention provides a module schematic diagram of an energy-saving control system based on an elevator. DETAILED DESCRIPTION

[0057] Reference Figures 1 to 2 shown.

[0058] The embodiment further illustrates an elevator-based energy-saving control method and system proposed by the present invention.

[0059] An energy-saving control method based on an elevator, the method comprising the following steps:

[0060] S1, associate at least two elevators in the same building that can reach the same floor and mark them as associated elevators;

[0061] S2, obtaining the status information of passengers waiting for the elevator at each associated elevator on each elevator stop floor, and obtaining the status information of each associated elevator in operation;

[0062] The status information of the passengers waiting for the elevator includes the passengers' intention to take the elevator, the floor where the passengers are waiting for the elevator, and the number of passengers waiting for the elevator; the status information of the associated elevator when it is running includes the number of passengers already carried in the associated elevator when it is running, the number of passengers accommodated when the associated elevator is fully loaded, the carrying intention information of the passengers in the associated elevator when it is running, and the running trend information of the associated elevator;

[0063] S3, processing and analyzing the number of people already carried by the associated elevator during operation, the number of people that the associated elevator can accommodate when fully loaded, the carrying intention information of the passengers in the associated elevator during operation, and the floor information of the passengers waiting for the elevator to obtain the carrying status of the associated elevator;

[0064] S4, if the load condition of the associated elevator meets the requirements, the operation trajectory energy-saving path instruction is generated based on the operation trend information of the associated elevator, the intention information of the passengers waiting for the elevator, the floor information of the passengers waiting for the elevator, and the number of passengers waiting for the elevator;

[0065] S5, controlling the operation of the associated elevator according to the energy-saving path instruction of the running trajectory, and reminding the elevator waiting person to wait in the corresponding elevator area on the floor.

[0066] Since there are multiple elevators that can reach the same floor in the same building, in order to achieve collaborative management, this application associates at least two elevators in the same building that can reach the same floor and marks them as associated elevators. For example, in an office building, there may be 6 elevators that can reach floors 1-30. The system will mark these 6 elevators as associated elevators. This association marking provides the basis for subsequent energy-saving control and optimized operation.

[0067] This application can continuously collect the status information of passengers waiting for the elevator at each associated elevator on each floor where the elevators stop, and can obtain the status information of each associated elevator during operation. The status information of passengers waiting for the elevator mainly includes the intention to take the elevator, the floor where the passengers waiting for the elevator are located, and the number of passengers waiting for the elevator.

[0068] The following three methods are used to obtain the elevator waiting person's intention to take the elevator: the first method is to identify the identity of the elevator waiting person through facial recognition technology, and match it with the frequently used destination information preset by the elevator waiting person to obtain the intention to take the elevator. After identification, the possible destination can also be predicted based on historical riding data; the second method is to develop a special elevator application, and the elevator waiting person selects the target floor in advance on the mobile phone. The system obtains the elevator waiting person's intention to take the elevator by connecting to the elevator control system; the third method is to install a voice recognition device in the elevator hall, and the elevator waiting person speaks the target floor by voice, and the system recognizes and records the intention to take the elevator.

[0069] The facial recognition camera installed in the elevator hall can be used to first identify the identity of the person waiting for the elevator, and then combined with the positioning device in the elevator hall, the floor location of the person waiting for the elevator can be accurately determined.

[0070] This application installs a camera in the elevator hall to detect and count the human bodies in the monitoring image, and can count the number of people waiting for the elevator in real time. For example, different individuals can be distinguished through human contour recognition, head detection, etc. to achieve counting.

[0071] The status information of the associated elevator during operation includes the number of passengers already carried in the associated elevator during operation, the number of passengers accommodated when the associated elevator is fully loaded, the carrying intention information of the passengers in the associated elevator during operation, and the operating trend information of the associated elevator.

[0072] Since cameras are installed inside the associated elevators, the cameras can capture the number of people already inside the associated elevators during operation. Since each model of associated elevators stipulates the number of people it can accommodate when fully loaded, after obtaining the model of the associated elevator, the number of people it can accommodate when fully loaded can be obtained.

[0073] By setting up a voice recognition system inside the associated elevator, the carrier can interact with the elevator through voice commands. The person waiting for the elevator says his or her destination floor, and the voice recognition system converts the voice information into text and analyzes it to obtain the carrier's carrying intention.

[0074] The direction sensor can be installed on the elevator's drive system or related mechanical components to detect the elevator's running direction and determine whether the elevator is running up or down, thereby obtaining the running direction information of the associated elevator.

[0075] This application combines the number of people already carried in the associated elevator during operation, the number of people accommodated when the associated elevator is fully loaded, the carrying intention information of the people carrying the passengers in the associated elevator during operation, and the floor information of the people waiting for the elevator to obtain the carrying status of the associated elevator.

[0076] If the analysis shows that the carrying conditions of the associated elevator meet the requirements, this application will further conduct in-depth processing and analysis based on the operating trend information of the associated elevator, the elevator waiting passengers' intention information, the floor information of the waiting passengers and the number of waiting passengers to generate an energy-saving path instruction for the operating trajectory.

[0077] This application precisely controls the associated elevators based on the generated energy-saving path instructions for the running trajectory. At the same time, this application reminds passengers waiting for the elevator to wait in the corresponding elevator area on their floor through the display screen, voice prompts, or mobile phone applications in the elevator hall. For example, when the system determines that a certain associated elevator will stop at a certain floor to pick up passengers waiting for the elevator, a prompt message "How many people please go to elevator area X to wait" will be displayed on the display screen in the elevator hall on that floor, making it easier for passengers waiting for the elevator to accurately find the corresponding elevator, realizing efficient and orderly operation of the elevator system. At the same time, other elevators will not stop at that floor, thereby achieving the purpose of energy saving for the elevator.

[0078] The carrying intention information of the internal carrier when the associated elevator is running is specifically the arrival floor information designated by the internal carrier when the associated elevator is running;

[0079] The operation trend information of the associated elevator specifically refers to the associated elevator running from top to bottom toward the floor where the passengers are waiting for the elevator or the associated elevator running from bottom to top toward the floor where the passengers are waiting for the elevator.

[0080] The following steps are also included:

[0081] Divide the floor areas of the building that can be reached by the associated elevator into an elevator waiting area and an elevator going area, count the number of people waiting for the elevator in the elevator waiting area and mark them as the first waiting number;

[0082] Obtain the walking speed information of each passenger in the area to which the elevator is heading, and the distance between each passenger and the elevator room. Calculate the time it takes for each passenger in the area to which the elevator is heading to move to the elevator room based on the walking speed information and the distance between each passenger and the elevator room.

[0083] Obtain the vertical distance between the location of the associated elevator and the floor where the passengers are waiting for the elevator, and the speed information of the associated elevator during operation, and calculate the time it takes for the associated elevator to run to the floor based on the speed information and the vertical distance value of the associated elevator during operation;

[0084] Count the total number of passengers on the floor whose time for each passenger to move to the elevator room is less than or equal to the time for the associated elevator to reach the floor, and mark them as the second waiting number;

[0085] The first number of people waiting and the second number of people waiting are cumulatively calculated to obtain the number of people waiting to take the elevator.

[0086] Based on the building's floor layout and the actual service range of the elevator, this application divides the areas on each floor accessible by the associated elevator into the elevator waiting area and the elevator arrival area. The elevator waiting area mainly refers to the relatively fixed waiting space in and around the elevator lobby, where passengers wait for the elevator to arrive; the elevator arrival area mainly refers to the corridor leading to the elevator lobby. For example, in an office building, there are corridors leading from the office doors of different companies to the elevator lobby. People use these corridors to take the elevator, so this corridor area is marked as the elevator arrival area.

[0087] Since the present application installs a camera in the elevator waiting area, the camera can identify and count the number of people waiting for the elevator in the elevator waiting area and mark it as the first waiting number.

[0088] In order to obtain relevant information about each elevator passenger in the elevator destination area, a high-definition camera is installed in the elevator destination area. The video images captured by the camera are used to measure the moving speed of each elevator waiting person. At the same time, combined with the electronic map of the floor, the distance between each elevator waiting person and the elevator can be accurately determined.

[0089] After obtaining the walking speed information and distance, the system calculates the walking time for each person waiting for an elevator in the elevator area by using the walking speed information of each person waiting for an elevator and the distance between each person and the elevator. For example, if the distance between a person waiting for an elevator and the elevator is 30 meters, and the video analysis shows that their walking speed is 1 meter per second, then the walking time for this person to reach the elevator is 30 seconds. The system will create a corresponding time record for each person waiting for an elevator, which can be compared with the elevator operation time.

[0090] The elevator itself is equipped with a comprehensive control system and various sensor devices. Using floor sensors installed in the elevator shaft, such as photoelectric sensors or magnetic sensors, the elevator can accurately determine its location in real time. At the same time, the elevator's drive system provides real-time feedback on operating speed information.

[0091] The time it takes for an elevator to reach a certain floor is calculated based on the vertical distance between the elevator's location and the floor where passengers are waiting, as well as the elevator's speed. For example, if the elevator is 60 meters away from a floor and is traveling at a speed of 2 meters per second, the time it takes for the elevator to reach that floor is 30 seconds. This data is transmitted to the central control system in real time and compared with data on passengers waiting in the area to which the elevator is headed.

[0092] The system compares the time it takes for each passenger to reach the elevator in the area they are traveling to with the time it takes the associated elevator to reach that floor. The system automatically selects passengers whose time to reach the elevator is less than or equal to the time it takes the associated elevator to reach that floor.

[0093] For example, let's assume there are five people waiting for an elevator in the elevator area. Their walking time to the elevator is 25 seconds, 35 seconds, 20 seconds, 40 seconds, and 30 seconds, respectively, while the elevator takes 30 seconds to reach that floor. The system will then count the three people waiting for an elevator with a walking time of 25 seconds, 20 seconds, and 30 seconds, because they were able to reach the elevator in time when the elevator arrived at that floor. The total number of these three people waiting for an elevator is the second number of people waiting.

[0094] Finally, the first and second waiting numbers are added together to get the final number of people waiting for the elevator. This accurate number information will be quickly fed back to the elevator's intelligent control system. The control system will control the related elevators to operate efficiently and energy-savingly based on this data, providing better elevator services for people waiting for the elevator.

[0095] The S3 step specifically includes:

[0096] The number of passengers in the associated elevator that has changed when the associated elevator arrives at the floor where the passengers are waiting is obtained according to the information of the floor where the passengers are waiting and the carrying intention information of the passengers in the associated elevator when the elevator is running;

[0097] The actual number of passengers carried in the associated elevator is calculated by calculating the change in the number of passengers carried in the associated elevator when the associated elevator arrives at the floor where the passengers are waiting for the elevator and the number of passengers carried in the associated elevator during operation;

[0098] If the actual number of people carried in the associated elevator is less than the number of people that the associated elevator can accommodate when fully loaded, the carrying conditions of the associated elevator meet the requirements.

[0099] This application first obtains the floor information of the passengers waiting for the elevator and the carrying intention information of the passengers inside the associated elevator when it is running. Then a comparative analysis is performed. If the target floor of the passengers in the associated elevator is the same as the floor of the passengers waiting for the elevator, then when the elevator arrives at that floor, these passengers will leave the elevator, and the number of these passengers is the number of passengers who have changed in the associated elevator. For example, if there are 15 passengers in an associated elevator, and the target floor of 3 of them happens to be the floor where there are passengers waiting for the elevator, then when arriving at that floor, the number of passengers who have changed in the associated elevator is expected to be 3.

[0100] If the elevator originally had 15 people inside and the expected change is 3 people (i.e., 3 people will get off the elevator), then the actual number of people inside the associated elevator when it arrives at that floor is 12. This step can accurately determine the actual passenger capacity of the elevator when it arrives at a specific floor in real time.

[0101] The calculated actual number of people inside the associated elevator is compared with the number of people the elevator would have accommodated at full capacity. If the actual number of people is less than the full capacity, for example, if an elevator has a full capacity of 20 but an actual number of people is 12, the elevator has remaining capacity and is considered to meet the required capacity. This determination serves as an important basis for subsequent energy-saving elevator operation scheduling (such as whether to stop at that floor).

[0102] Step S4 specifically includes:

[0103] The number of passengers that the associated elevator can accommodate when fully loaded and the actual number of passengers inside the associated elevator are calculated to obtain the actual remaining number of passengers that can be accommodated inside the associated elevator;

[0104] The operation trend information of the elevator, the intention information of the passengers waiting for the elevator, the actual number of passengers remaining in the elevator and the number of passengers waiting for the elevator are processed to generate an energy-saving path instruction for the operation trajectory.

[0105] The operation trend information of the elevator, the intention information of the passengers waiting for the elevator, the actual number of passengers remaining in the elevator and the number of passengers waiting for the elevator are processed to generate the operation trajectory energy-saving path instruction, which specifically includes the following steps:

[0106] Determine whether the associated elevator needs to stop when passing the floor where the passenger is waiting for the elevator based on the operating trend information of the associated elevator and the passenger's intention to take the elevator;

[0107] When it is determined that the associated elevator needs to stop at the floor where the passengers are waiting, the actual remaining number of passengers inside the associated elevator is compared with the number of passengers waiting to be loaded, and then the first execution trajectory path instruction, the second execution trajectory path instruction, the third execution trajectory path instruction, the fourth execution trajectory path instruction, and the fifth execution trajectory path instruction are generated.

[0108] This application obtains in real time the associated elevator's operating direction information (i.e., whether the elevator is traveling from top to bottom or bottom to top) and the passenger's intended direction (the direction the passenger wants to go, up or down). When the two directions are the same, for example, if the passenger is on a certain floor and preparing to go to a higher floor while the associated elevator is traveling upward, the system will directly determine that the associated elevator needs to stop when passing the passenger's floor to pick up the passenger.

[0109] Determining whether the associated elevator needs to stop when passing the floor where the passenger is waiting for the elevator based on the operating trend information of the associated elevator and the passenger's intention information includes the following steps:

[0110] If the running direction information of the associated elevator is consistent with the direction of the elevator intention information of the elevator waiting person, it is determined that the associated elevator needs to stop when passing the floor where the elevator waiting person is located;

[0111] If the running direction information of the associated elevator is inconsistent with the direction of the elevator waiting person's intention to take the elevator, the carrying intention information of the passengers inside the associated elevator during operation and the floor information of the waiting passengers are processed and analyzed to determine whether the associated elevator needs to stop when passing the floor where the waiting passengers are.

[0112] If the associated elevator's running direction information is found to be consistent with the direction of the person waiting for the elevator, for example, if the person waiting for the elevator is traveling from the 5th floor to the 10th floor, and a related elevator is traveling upward from a lower floor and is about to reach the 5th floor, the system will immediately determine that the associated elevator needs to stop when passing the 5th floor. This is because in this case, the elevator's running direction matches the travel needs of the person waiting for the elevator, and the stop can directly meet the person's needs and achieve efficient personnel transportation. The system then sends a stop instruction to the elevator and notifies the waiting passenger of the elevator's imminent arrival through the floor display or other prompting devices.

[0113] If the system determines that the associated elevator's running direction information is inconsistent with the waiting passenger's intended direction, for example, a waiting passenger on the 8th floor needs to go to the 1st floor, while a related elevator is running upwards, the system will further process and analyze the associated elevator's internal passenger's intended direction information and the waiting passenger's current floor information.

[0114] The designated arrival floor information for passengers within an associated elevator refers to the designated arrival floor for passengers within the elevator during operation. This information is also transmitted to the central processing system in real time. The system checks each passenger's destination floor to see if any matches the floor where the passenger is waiting (i.e., the 8th floor). If a passenger's destination floor is the 8th floor, indicating that a passenger will disembark upon arrival and there will be free space inside the elevator, the system will determine that the associated elevator needs to stop at the 8th floor to pick up the passenger. Conversely, if no passenger is disembarking at the 8th floor, indicating that there is no available space at that floor, the system will determine that the associated elevator does not need to stop at that floor and will continue on its original route.

[0115] For example, the associated elevator runs from top to bottom toward the floor where the passengers are waiting for the elevator. However, the passengers' intention information for taking the elevator is to go from the 5th floor to the 10th floor. Therefore, the running direction information of the associated elevator and the direction of the passengers' intention information for taking the elevator are inconsistent. If the carrying intention information of the passengers inside the associated elevator is the floor where the passengers are waiting for the elevator, some of the passengers inside the associated elevator need to leave the elevator at the floor where the passengers are waiting for the elevator, that is, the associated elevator needs to stop at that floor, thus reminding the passengers waiting for the elevator on that floor that they are about to take the elevator.

[0116] Then, after processing and analyzing the carrying intention information of the passengers inside the associated elevator and the floor information of the passengers waiting for the elevator, it is determined whether the associated elevator needs to stop when passing the floor where the passengers are waiting for the elevator, which specifically includes the following steps:

[0117] If the carrying intention information of the passengers inside the associated elevator is consistent with the floor information of the passengers waiting for the elevator, the associated elevator is determined to need to stop when passing the floor where the passengers are waiting for the elevator, and the number of passengers waiting on the floor where the passengers are waiting for the elevator is compared with the actual number of passengers remaining in the associated elevator, and the corresponding number of passengers waiting for the elevator is reminded to move to the associated elevator;

[0118] If the carrying intention information of the internal carrier of the associated elevator is inconsistent with the floor information of the person waiting for the elevator when the associated elevator is running, it is determined that the associated elevator does not need to stop when passing the floor where the person waiting for the elevator is.

[0119] If the loading intention information of the passengers in the associated elevator matches the floor information of the passengers waiting for the elevator, it means that the passengers will get off the elevator when the elevator arrives at that floor, creating a vacant seat. Then, through display screens, voice prompts, etc., the corresponding number of passengers waiting for the elevator will be reminded to move to the associated elevator, ensuring the rational use of elevator space and avoiding overcrowding.

[0120] If the carrying intention information of the passengers inside the associated elevator is inconsistent with the floor information of the passengers waiting for the elevator when the associated elevator is running, that is, there is no passenger in the elevator who wants to get off at that floor, the system will determine that the associated elevator does not need to stop when passing the floor where the passengers are waiting for the elevator, and let the elevator continue to run along the original route, reducing invalid stops and improving operating efficiency.

[0121] When it is determined that the associated elevator needs to stop at the floor where the passengers are waiting, the actual number of passengers remaining in the associated elevator is compared with the number of passengers waiting to board the elevator, and then an energy-saving path instruction for the running trajectory is generated, which specifically includes the following steps:

[0122] If there is at least one associated elevator whose actual remaining capacity is greater than or equal to the number of passengers waiting for the elevator, then one of the associated elevators whose actual remaining capacity is greater than or equal to the number of passengers waiting for the elevator is marked as the first execution associated elevator, and the remaining associated elevators are marked as the second execution associated elevators, and a first execution trajectory path instruction is generated for the first execution associated elevator, and a second execution trajectory path instruction is generated for the second execution associated elevator;

[0123] If the number of people actually remaining in each associated elevator is less than the number of people waiting to take the elevator, compare the total number of people actually remaining in all associated elevators with the number of people waiting to take the elevator;

[0124] If the sum of the actual remaining number of people that can be loaded in all associated elevators is greater than the number of people waiting for the elevators, then the associated elevator with the largest actual remaining number of people that can accommodate the number of people waiting for the elevators is marked as the third execution associated elevator, and the remaining associated elevators are marked as the fourth execution associated elevators. A third execution trajectory path instruction is generated for the third execution associated elevator, and a fourth execution trajectory path instruction is generated for the fourth execution associated elevator.

[0125] If the total number of people actually remaining in all associated elevators is equal to or less than the number of people waiting to board the elevators, all associated elevators are marked as fifth execution associated elevators, and a fifth execution trajectory path instruction is generated for the fifth execution associated elevators;

[0126] Among them, the first execution trajectory path instruction, the second execution trajectory path instruction, the third execution trajectory path instruction, the fourth execution trajectory path instruction, and the fifth execution trajectory path instruction are combined to form an operation trajectory energy-saving path instruction.

[0127] Controlling the operation of the associated elevators according to the energy-saving path instructions of the running trajectory specifically includes the following steps:

[0128] The first execution trajectory path instruction controls the first execution associated elevator to stop at the floor where the passenger is waiting, and the second execution trajectory path instruction controls the second execution associated elevator not to stop at the floor where the passenger is waiting;

[0129] The third execution trajectory path instruction controls the third execution associated elevator to stop at the floor where the passenger is waiting, and the fourth execution trajectory path instruction controls the fourth execution associated elevator not to stop at the floor where the passenger is waiting;

[0130] The fifth execution trajectory path instruction controls the fifth execution associated elevator to stop at the floor where the passengers are waiting.

[0131] This application first obtains relevant information about the associated elevators in real time, including the number of people already in each associated elevator and the number of people that can be accommodated when the elevator is fully loaded. By subtracting the two, the actual remaining number of people in each associated elevator is calculated. At the same time, the number of people waiting for the elevator on the floor where the people waiting for the elevator are located is accurately counted. These data form the basis for subsequent comparisons and decisions.

[0132] If at least one associated elevator has a remaining capacity greater than or equal to the number of passengers waiting for the elevator, it means that there is an elevator that can carry all passengers waiting for the elevator on that floor at once. At this time, the system will mark one of the associated elevators that meets the conditions as the first execution associated elevator, and the remaining associated elevators as the second execution associated elevators. For the first execution associated elevator, the system generates a first execution trajectory path instruction to control it to stop at the floor where the passengers are waiting for the elevator so as to pick up the passengers waiting for the elevator; for the second execution associated elevator, the system generates a second execution trajectory path instruction to prevent it from stopping at that floor and continue to operate according to the optimized path, thus avoiding unnecessary stops and energy consumption.

[0133] When the actual remaining capacity of each associated elevator is less than the number of people waiting for the elevator, the system will further calculate the sum of the actual remaining capacity of all associated elevators and compare it with the number of people waiting for the elevator. If the sum is greater than the number of people waiting for the elevator, it means that although a single elevator cannot accommodate all the people waiting for the elevator, the demand can still be met by reasonably selecting several of them. At this time, the system will screen out the associated elevator with the largest actual remaining capacity and the number of people waiting for the elevator, and mark it as the third execution associated elevator, and mark the remaining associated elevators as the fourth execution associated elevator. Then, a third execution trajectory path instruction is generated for the third execution associated elevator, so that it stops at the floor where the waiting passengers are and picks up the waiting passengers; a fourth execution trajectory path instruction is generated for the fourth execution associated elevator, so that it does not stop at that floor, in order to optimize the running path.

[0134] If the total number of passengers remaining in all associated elevators is equal to or less than the number of passengers waiting for the elevator, this means that the current associated elevator alone cannot carry all passengers. In this case, the system marks all associated elevators as fifth-execution associated elevators and generates fifth-execution trajectory instructions for them, controlling all elevators to stop at the floor where the passengers are waiting, carrying as many passengers as possible to meet their travel needs.

[0135] Finally, the first, second, third, fourth, and fifth execution trajectory instructions are combined to form a complete energy-saving operation trajectory. Based on these instructions, the elevator control system precisely controls the operation of each associated elevator, achieving efficient transportation of passengers and optimizing the allocation of elevator resources.

[0137] a marking module, which associates at least two elevators in the same building that can reach the same floor and marks them as associated elevators;

[0138] An acquisition module is used to obtain the status information of passengers waiting for the elevator at each associated elevator on each floor where the elevator stops, and to obtain the status information of each associated elevator during operation;

[0139] The status information of the passengers waiting for the elevator includes the passengers' intention to take the elevator, the floor where the passengers are waiting for the elevator, and the number of passengers waiting for the elevator; the status information of the associated elevator when it is running includes the number of passengers already carried in the associated elevator when it is running, the number of passengers accommodated when the associated elevator is fully loaded, the carrying intention information of the passengers in the associated elevator when it is running, and the running trend information of the associated elevator;

[0140] The processing and analysis module processes and analyzes the number of people already carried in the associated elevator during operation, the number of people that the associated elevator can accommodate when fully loaded, the carrying intention information of the people carried in the associated elevator during operation, and the floor information of the people waiting for the elevator to obtain the carrying status of the associated elevator;

[0141] The instruction generation module, if the carrying conditions of the associated elevator meet the requirements, generates an energy-saving path instruction based on the operation trend information of the associated elevator, the intention information of the passengers waiting for the elevator, the floor information of the passengers waiting for the elevator, and the number of passengers waiting for the elevator;

[0142] The control reminder module controls the operation of the associated elevator according to the energy-saving path instructions of the running trajectory, and reminds the people waiting for the elevator to wait in the corresponding elevator area on their floor.
