Description

Technical Field

[0001] This invention belongs to the technical field of elevator equipment, and specifically relates to an energy-saving elevator control method based on carbon footprint. Background Technology

[0002] Carbon footprint, also known as carbon consumption, is an indicator used to measure the environmental impact of carbon dioxide emissions generated by an organization or individual's daily energy consumption. The more carbon consumed, the more carbon dioxide, the culprit of global warming, is produced, resulting in a larger carbon footprint; conversely, the smaller the carbon footprint, the smaller the carbon footprint. An individual's carbon footprint can be divided into a primary carbon footprint and a secondary carbon footprint. The primary carbon footprint is the carbon dioxide emitted directly from the use of fossil fuels. The secondary carbon footprint is the carbon dioxide emitted indirectly from the use of various products, such as the emissions generated when passengers ride in an elevator.

[0003] From an energy perspective, elevator electricity consumption is a fundamental energy expenditure. Due to the complex internal mechanical structure and numerous electronic components of elevators, they are frequently started and stopped during use, resulting in significant electricity consumption. However, current technology lacks methods for measuring the carbon footprint of elevators during their use and for corresponding energy-saving control. Summary of the Invention

[0004] In order to overcome one or more defects and shortcomings of the existing technology, the purpose of this invention is to provide an elevator control energy-saving method based on carbon footprint, which can reduce the energy consumption and carbon emissions caused by elevator operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] A carbon footprint-based elevator control energy-saving method, implemented using a cloud platform, elevator system, visual recognition monitoring system, and carbon footprint measurement and control system, includes the following steps:

[0007] A visual recognition monitoring system is used to perform facial recognition, obtain the identity information of different users, and upload it to the cloud platform;

[0008] The visual recognition monitoring system acquires the elevator trajectory set of each user within a set period of time in the past, and then sends it to the carbon footprint monitoring and control system. The carbon footprint monitoring and control system finds the data of various carbon footprint objects generated by each user's elevator trajectory set within that period of time, and then uses the carbon footprint algorithm to statistically analyze and obtain the current carbon footprint data of each user, and uploads it to the cloud platform.

[0009] Based on the carbon footprint data of all users obtained by the cloud platform, the carbon footprint monitoring and control system counts the number of users calling the elevator system on different floors during different set time periods, and uses the floor with the most users as the base station during the corresponding set time period. Then, it sends a command message to the elevator system to activate the base station function, and the elevator system stops the elevator car at the floor corresponding to the base station during the corresponding set time period.

[0010] The carbon footprint monitoring and control system uses the carbon footprint data of all users to precisely control various carbon consumptions of the elevator system.

[0011] Preferably, after performing facial recognition, the visual recognition monitoring system further performs the following steps:

[0012] The visual recognition monitoring system determines whether there are any temporary users among the users;

[0013] When the visual recognition monitoring system determines that there are temporary users among the elevator passengers, the visual recognition monitoring system notifies the elevator system to enable the elevator authorization mode for the temporary users.

[0014] Long-term users can use their mobile devices to forward confirmation and authorization messages to the elevator system via the cloud platform, thus confirming the elevator access rights of the corresponding temporary users.

[0015] Furthermore, long-term users are defined as owners, property management personnel, security personnel, and long-term residents. The visual recognition monitoring system identifies whether there are temporary users by pre-recorded facial image data.

[0016] Furthermore, after the corresponding long-term user sends a confirmation of the temporary user's access rights to the elevator system via their mobile terminal, the following steps are also performed:

[0017] The carbon footprint monitoring and control system marks the elevator travel trajectory of the temporary user as the elevator travel trajectory of the corresponding long-term user.

[0018] Preferably, the data for various carbon footprint objects comes from the power consumption of various electrical components in the elevator system.

[0019] Preferably, after obtaining the carbon footprint data of each user using a carbon footprint algorithm for statistical analysis, the following steps are also performed:

[0020] The carbon footprint data of all users is analyzed using clustering statistics.

[0021] Preferably, after the elevator system activates the base station function, the following steps are also performed:

[0022] The visual recognition monitoring system also identifies whether any users are approaching the elevator system at the floors the elevator car passes through during its ascent and descent.

[0023] When the visual recognition monitoring system detects that a user is approaching the elevator system, it sends a selective waiting instruction message to the elevator system. Then, the elevator system controls the elevator car to not move up or down to other floors within a set time period, thus waiting for the detected user to call the elevator car through the external call panel of the elevator system.

[0024] If a user does not call the elevator system within a set time period, or if the direction of the call is different from the current elevator car's direction of movement, the elevator system will control the elevator car to move to another floor to respond to other users.

[0025] Preferably, the carbon footprint of the elevator system is divided according to power level, and the energy consumption of high-power devices and low-power devices is managed in four levels.

[0026] Furthermore, the four levels of control are as follows:

[0027] Level 1 control is used for high-power devices, setting the corresponding high-power devices to be enabled;

[0028] Level 2 control is used for elevator door operator opening and closing, and sets the activation of corresponding high-power devices in the elevator door operator;

[0029] Level 3 control is used for external call panels, control panel panels, car fans, and lighting fixtures, setting the activation of the external call panel's illuminated display, and activating the elevator car's control panel panels, car fans, and lighting fixtures;

[0030] Level 4 control is used for weak electronic devices, and the external call panel is set to enable weak display.

[0031] Furthermore, precise control over various carbon consumption processes in elevator systems is implemented, including the following steps:

[0032] When the elevator car is in operation, the first-level control is activated at full power, the second-level control is activated at full power, the third-level control is activated at 30% of the total carbon consumption of the elevator system, and the fourth-level control is activated at 30% of the total carbon consumption of the elevator system.

[0033] When the elevator car enters standby mode, Level 1, Level 2, and Level 3 controls activate low-energy mode based on 30% of the total carbon consumption of the elevator system, while Level 4 controls enter screen-off mode based on 10% of the power of the weak electronic devices themselves.

[0034] When the elevator car switches from standby mode to running mode, the four-level control, three-level control, two-level control, and one-level control are gradually activated until the one-level control is restored to full power, the two-level control is restored to full power, the three-level control is activated at 30% of the total carbon consumption of the elevator system, and the four-level control is activated at 30% of the total carbon consumption of the elevator system.

[0035] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0036] This invention effectively reduces energy consumption and carbon emissions during elevator operation by controlling the elevator's operation in an energy-efficient manner. It also improves the elevator's passenger carrying efficiency, avoids excessive repetitive operation, and helps extend the elevator's actual service life. Attached Figure Description

[0038] Figure 2 for Figure 1 A schematic diagram of the existing elevator-related system framework used in the Chinese method. Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Example

[0040] like Figure 1 , Figure 2 As shown in this embodiment, an elevator control energy-saving method based on carbon footprint is executed by a cloud platform, an elevator system, a visual recognition monitoring system, and a carbon footprint measurement and control system. The elevator system, the visual recognition monitoring system, and the carbon footprint measurement and control system are electrically connected for data transmission.

[0041] The elevator system performs transportation functions, transmits relevant power consumption data to the carbon footprint monitoring and control system, and receives energy-saving operation instructions from the carbon footprint monitoring and control system. The visual recognition and monitoring system detects and identifies whether a person entering the elevator system is a long-term or temporary user and controls their access permissions accordingly. The carbon footprint monitoring and control system collects carbon footprint calculation-related data from the elevator system and the visual recognition and monitoring system, and then uses a carbon footprint algorithm to statistically analyze the carbon footprint of each long-term user of the elevator system. The carbon footprint data collected includes the start / stop of various electronic switches in the elevator system, power distribution, and current flow, and is linked to the elevator usage data of each user in the visual recognition and monitoring system. The cloud platform communicates with the elevator system, the visual recognition and monitoring system, and the carbon footprint monitoring and control system for data transmission. Relevant data from the elevator system, the visual recognition and monitoring system, and the carbon footprint monitoring and control system during operation are all uploaded to the cloud platform. Preferably, in this embodiment, the carbon footprint monitoring and control system runs on a local computing server. The visual recognition and monitoring system sends instructions to the elevator system through the cloud platform to control users' access permissions. Data transmission between the cloud platform and users is conducted via mobile terminals. The cloud platform also stores facial information, identity information, and elevator travel trajectories for different users. In other implementations, the visual recognition monitoring system can also bypass the cloud platform and connect directly to the elevator system for data and / or command transmission.

[0042] This embodiment of an elevator control energy-saving method based on carbon footprint includes the following steps:

[0043] S1. Use a visual recognition monitoring system to perform facial recognition, obtain the identity information of different users, and upload the recognition results to the cloud platform.

[0044] In this preferred embodiment, after the visual recognition monitoring system performs facial recognition, it can execute the following steps:

[0045] S11. The visual recognition monitoring system determines whether there are any temporary users among the users;

[0046] S12. When the visual recognition monitoring system determines that there are temporary users among the passengers, the visual recognition monitoring system sends a data message to the elevator system through the cloud platform. The elevator system opens the elevator authorization mode for temporary users and sets that temporary users who have not obtained elevator authorization cannot call or ride the elevator car.

[0047] In a further preferred embodiment, the elevator system simultaneously uses voice or a display screen to notify temporary users and the corresponding long-term users; long-term users are defined as owners, property management personnel, security personnel, and long-term residents, and their facial image data can be pre-recorded in the visual recognition monitoring system;

[0048] S13. Long-term users use mobile terminals to forward confirmation authorization messages to the elevator system through the cloud platform, confirm the elevator access rights of the corresponding temporary users, and remove the restriction that temporary users cannot call or ride the elevator car during this trip.

[0049] Steps S11-S13 can prevent unauthorized personnel from using the elevator system, thereby reducing carbon emissions;

[0050] In a further preferred embodiment, after the long-term user sends a confirmation of the temporary user's elevator access rights to the elevator system via a mobile terminal, the following steps can also be performed:

[0051] S14. The carbon footprint monitoring and control system marks the elevator travel trajectory of the temporary user as the elevator travel trajectory of the corresponding long-term user; step S14 can facilitate the statistical analysis of the actual carbon consumption related to long-term users.

[0052] S2. The visual recognition monitoring system acquires the elevator trajectory set of each user within a set period of time in the past, and then sends it to the carbon footprint monitoring and control system. The carbon footprint monitoring and control system finds the data of various carbon footprint objects generated by each user's elevator trajectory set within that period of time, and then uses the carbon footprint algorithm to statistically analyze and obtain the current carbon footprint data of each user. At the same time, all carbon footprint data is uploaded to the cloud platform.

[0053] In this preferred embodiment, the data of various carbon footprint objects generated corresponding to the elevator trajectory set during this time period comes from the power consumption of various electrical components of the elevator system, including but not limited to motors, electrical switches, microelectronic components, lighting fixtures, etc.

[0054] In this embodiment, the set time period in step S2 can be specifically set to 3 to 30 days or even longer.

[0055] S3. Based on the carbon footprint data of all users obtained by the cloud platform in step S2, the carbon footprint monitoring and control system counts the number of users calling the elevator system on different floors during different set time periods, and uses the floor with the most users as the base station during the corresponding set time period. Then, it sends an instruction message to the elevator system to start the base station function, and the elevator system stops the elevator car at the floor corresponding to the base station during the corresponding set time period.

[0056] In this preferred embodiment, after obtaining the carbon footprint data of each user using a carbon footprint algorithm for statistical analysis, the carbon footprint data of all users are analyzed by clustering statistics; the clustering labels include the floor used, different types of devices, etc.

[0057] In this preferred embodiment, after the elevator system activates the base station function, the following steps can be performed:

[0058] S31. The visual recognition monitoring system simultaneously identifies whether any users are approaching the elevator system at the floors the elevator car passes through during its ascent and descent.

[0059] S32. When the visual recognition monitoring system detects that a user is approaching the elevator system, it sends a selective waiting instruction message to the elevator system. Then, the elevator system controls the elevator car to not move up or down to other floors within a set time period, thereby waiting for the detected user to call the elevator car through the external call panel of the elevator system.

[0060] S33. If, within a set time period, the identified user does not call the elevator system, or the direction of the call is different from the current elevator car's direction of movement, the elevator system controls the elevator car to move to other floors to respond to other users.

[0061] In this preferred embodiment, the time period set in steps S32 and S33 can be set to 5 to 30 seconds, or a shorter duration.

[0062] Steps S31-S33 can avoid the problem of increased carbon consumption of the elevator system caused by the need to restart the elevator car to the user's floor because the user missed the elevator car.

[0063] S4. The carbon footprint monitoring and control system performs fine control over various carbon consumptions of the elevator system based on the carbon footprint data of all users obtained in step S2.

[0064] In this preferred embodiment, the carbon consumption of the elevator system is analyzed starting from the 380V high-voltage input of the power supply box. The system tracks the switching and starting usage, power distribution, and microcurrent flow of electrical appliances inside the elevator system. The carbon footprint is then divided according to power level, and the energy consumption of high-power devices and low-power devices is managed in four levels.

[0065] In this preferred embodiment, the carbon footprint monitoring and control system provides the following four levels of control over the elevator system:

[0066] (1) Level 1 control is used for high-power devices such as frequency converters and traction machines in the control cabinet (380V power input), and can determine the opening or closing of the secondary control devices; the content of Level 1 control is: setting the corresponding high-power devices to be turned on, corresponding to the operation of the main control cabinet, frequency converter and traction machine;

[0067] (2) The secondary control is used for the opening and closing of the elevator door machine (220V power input) and can determine the opening or closing of the tertiary control device; the content of the secondary control is: setting the corresponding high-power device to be turned on, corresponding to the operation of the elevator door machine;

[0068] (3) Level 3 control is used for the operation of external call panel, control box panel, car fan and lighting (24V power input), and can determine the opening or closing of level 4 control devices; the content of level 3 control is: setting the external call panel to light up, and the elevator car control box panel, car fan and lighting fixtures to be turned on;

[0069] (4) Level 4 control is used for weak electronic devices (12V and below), such as the weak display of the external call panel; the content of Level 4 control is: setting the external call panel to enable the weak display;

[0070] The specific steps for precise control of various carbon consumption processes in elevator systems are as follows:

[0071] S41. When the elevator car is in operation:

[0072] Activate full power for both Level 1 and Level 2 control systems to ensure the normal operation of the main control cabinet, frequency converter, traction machine, and elevator door operator;

[0073] Level 3 control is activated at 30% of the total carbon consumption of the elevator system. Level 4 control is activated at 30% of the total carbon consumption of the elevator system. Only the bright display of the external call panel of the target floor and the current floor, the control panel of the elevator car, the car fan and lighting fixtures are guaranteed to be in normal operation, while the external call panel of the non-service floors is in weak display mode.

[0074] S42. When the elevator car enters standby mode: Level 1 control, Level 2 control, and Level 3 control are activated to enter low energy consumption mode according to 30% of the total carbon consumption of the elevator system, and Level 4 control is activated to enter screen-off mode according to 10% of the power of the weak electronic devices themselves.

[0075] S43. When the elevator car switches from standby mode to running mode, gradually activate level 4 control, level 3 control, level 2 control, and level 1 control to restore the fine control mode in step S41.

[0076] S5. During the execution of steps S1-S4, the visual recognition monitoring system, elevator system, and carbon footprint measurement and control system simultaneously transmit the corresponding data and instruction records to the cloud platform for backup.

[0077] Compared with existing technologies, the carbon footprint-based elevator control energy-saving method of this embodiment has the following advantages:

[0078] This embodiment effectively reduces energy consumption and carbon emissions during elevator operation by controlling the elevator's operation in an energy-efficient manner. It also improves the elevator's passenger carrying efficiency, avoids excessive repetitive operation, and helps extend the elevator's actual service life.

[0079] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
