Description

Technical Field

[0001] The present invention belongs to the technical field of elevator equipment, and in particular relates to an elevator control energy-saving method based on carbon footprint. Background Art

[0002] Carbon footprint is also commonly referred to as "carbon consumption". It refers to an indicator used to measure the environmental impact of carbon dioxide emissions generated by daily energy consumption by organizations or individuals. The more "carbon" is consumed, the more "carbon dioxide" that causes global warming is produced, and the larger the "carbon footprint"; conversely, the smaller the "carbon footprint". A person's carbon footprint can be divided into the first carbon footprint and the second carbon footprint. The first carbon footprint is the carbon dioxide emitted directly due to the use of fossil energy. The second carbon footprint is the carbon dioxide emitted indirectly due to the use of various products, such as the carbon footprint caused by the emissions generated by passengers taking the elevator.

[0003] From an energy perspective, elevator power consumption is a basic consumption. Due to the complex internal mechanical structure and numerous electronic devices of elevators, elevators are frequently started during use, resulting in huge power consumption. However, in the existing technology, there is a lack of methods to measure the carbon footprint of elevators and control energy consumption accordingly. Summary of the invention

[0004] In order to overcome one or more defects and shortcomings of the prior art, the purpose of the present invention is to provide an elevator control energy-saving method based on carbon footprint, which is used to achieve the effect of reducing the energy consumption of elevator operation and the carbon emissions caused.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions.

[0006] An elevator control energy-saving method based on carbon footprint is implemented using a cloud platform, an elevator system, a visual recognition monitoring system, and a carbon footprint measurement and control system, and includes the following steps: Use the visual recognition monitoring system to perform face recognition, obtain the identity information of different users, and upload it to the cloud platform; The visual recognition monitoring system obtains the set of elevator trajectories of each user within a set period of time in the past, and then sends it to the carbon footprint measurement and control system. The carbon footprint measurement and control system accordingly finds the data of various carbon footprint objects generated by the set of elevator trajectories of each user within the period, and then uses the carbon footprint algorithm for statistical analysis to obtain the carbon footprint data of each user at present, and uploads it to the cloud platform; Based on the carbon footprint data of all users obtained by the cloud platform, the carbon footprint measurement and control system counts the number of users who call the elevator system on different floors during different set time periods, and uses the floor with the largest number of users as the base station during the corresponding set time period, and then sends a command message to the elevator system to start the base station function. The elevator system then stops the elevator car at the floor corresponding to the base station during the corresponding set time period; The carbon footprint measurement and control system conducts precise control of various carbon consumption of the elevator system based on the carbon footprint data of all users obtained.

[0007] Preferably, after the visual recognition monitoring system performs face recognition, the following steps are further performed: The visual recognition monitoring system determines whether there are temporary users among the users; When the visual recognition monitoring system determines that there is a temporary user among the passengers, the visual recognition monitoring system notifies the elevator system to start the elevator authorization mode for the temporary user; Long-term users use mobile terminals to forward through the cloud platform and send confirmation authorization instruction messages to the elevator system to confirm the corresponding temporary users' elevator rights.

[0008] Furthermore, long-term users are set as owners, property managers, security personnel, and long-term residents, and the visual recognition monitoring system identifies whether there are temporary users through pre-entered facial image data.

[0009] Furthermore, after the corresponding long-term user sends an operation to confirm the corresponding temporary user's elevator authority to the elevator system through the mobile terminal, the following steps are also performed: The carbon footprint measurement and control system marks the temporary user's elevator trajectory as the corresponding long-term user's elevator trajectory.

[0010] Preferably, the data of various carbon footprint objects come from the power consumption of various electrical devices in the elevator system.

[0011] Preferably, after obtaining the carbon footprint data of each user through statistical analysis using the carbon footprint algorithm, the following steps are further performed: The carbon footprint data of all users are analyzed through cluster statistics.

[0012] Preferably, after the elevator system starts the base station function, the following steps are further performed: The visual recognition monitoring system also identifies whether there is a user approaching the elevator system at the floor position passed during the current elevator car ascending and descending process; When the visual recognition monitoring system identifies that a user is approaching the elevator system, a selective waiting instruction message is sent to the elevator system, and then the elevator system controls the elevator car not to ascend or descend to other floors within a set period of time, thereby waiting for the identified user to call the elevator car through the elevator system's call panel; If the identified user does not call the elevator system within the set time period, or the lifting direction of the call is different from the lifting direction of the current elevator car, the elevator system controls the elevator car to lift to other floors to respond to other users.

[0013] Preferably, the various carbon consumptions of the elevator system divide the carbon footprint according to the power size, and the energy of high-power devices and low-power devices is managed and controlled at four levels.

[0014] Furthermore, the four levels of control are as follows: The first-level control is used for high-power devices, setting the corresponding high-power devices to be turned on; Secondary control is used for opening and closing the elevator door machine, setting the corresponding high-power devices of the elevator door machine to be turned on; The three-level control is used for the hall call panel, control box panel, car fan, and lighting fixtures. The bright display of the hall call panel is set to be turned on, and the control box panel, car fan, and lighting fixtures of the elevator car are turned on; The fourth level of control is used for weak electronic devices, and the external call panel is set to open the weak display.

[0015] Furthermore, the various carbon consumption of the elevator system is finely controlled, including the following steps: When the elevator car is in operation, turn on the first-level control at full power, the second-level control at full power, the third-level control at 30% of the total carbon consumption of the elevator system, and the fourth-level control at 30% of the total carbon consumption of the elevator system; When the elevator car enters the standby state, the first-level control, second-level control, and third-level control are activated and enter the low-energy consumption mode according to 30% of the total carbon consumption of the elevator system, and the fourth-level control enters the screen-off state according to 10% of the power of the weak electronic devices themselves; When the elevator car switches from standby mode to operating mode, the fourth-level control, third-level control, second-level control, and first-level control are gradually turned on until the first-level control is restored to full power, the second-level control is restored to full power, the third-level control is activated according to 30% of the total carbon consumption of the elevator system, and the fourth-level control is activated according to 30% of the total carbon consumption of the elevator system.

[0016] Compared with the prior art, the technical solution of the present invention has the following beneficial effects: The present invention can effectively reduce energy consumption and carbon emissions during the use of the elevator by performing energy-saving control on the elevator operation process, improve the elevator's passenger efficiency while avoiding excessive repeated operation of the elevator, and help to extend the actual service life of the elevator.

[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments thereof. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Example

[0019] like Figure 1 , Figure 2 As shown, a carbon footprint-based elevator control energy-saving method of this embodiment 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 to each other for data transmission.

[0020] The elevator system is used to perform the transport function, transmit the corresponding power consumption data to the carbon footprint measurement and control system, and receive the energy-saving operation instructions of the carbon footprint measurement and control system. The visual recognition monitoring system is used to detect and identify whether the person who needs to enter the elevator system is a long-term user or a temporary user and control the corresponding elevator riding privileges. The carbon footprint measurement and control system is used to collect data related to carbon footprint calculation from the elevator system and the visual recognition monitoring system, and then use the carbon footprint algorithm to statistically analyze the carbon footprint of each long-term user of the elevator system. The objects of carbon footprint collection include the start and stop of various electronic switches in the elevator system, power distribution, and current flow, and bind the data of the elevator usage of each user in the visual recognition monitoring system. The cloud platform communicates with the elevator system, the visual recognition monitoring system, and the carbon footprint measurement and control system for data transmission, and the relevant data of the elevator system, the visual recognition monitoring system, and the carbon footprint measurement and control system during operation are uploaded to the cloud platform. In this embodiment, the carbon footprint measurement and control system is preferably run in a local computing server, and the visual recognition monitoring system sends instructions to the elevator system to control the user's elevator riding privileges through the cloud platform. The cloud platform and the user transmit data through a mobile terminal, and the cloud platform is also used to store the facial information, identity information, and elevator riding trajectory of different users. In other embodiments, the visual recognition monitoring system may bypass the cloud platform and directly connect to the elevator system to transmit data and / or instructions.

[0021] An elevator control energy saving method based on carbon footprint of this embodiment includes the following steps: S1. Use the visual recognition monitoring system to perform face recognition, obtain the identity information of different users, and upload the recognition results to the cloud platform; In this embodiment, after the visual recognition monitoring system performs face recognition, the following steps may be performed: S11, the visual recognition monitoring system determines whether there are temporary users among the users; S12. When the visual recognition monitoring system determines that there is a temporary user among the passengers, the visual recognition monitoring system sends a data message to the elevator system through the cloud platform. The elevator system turns on the elevator authorization mode for the temporary user and sets that the temporary user who has not obtained the elevator authorization cannot call or take the elevator system's car; In this embodiment, the elevator system uses voice or display screen to inform temporary users to notify corresponding long-term users; long-term users are set as owners, property management, security personnel, and long-term residents, and their facial image data can be recorded in the visual recognition monitoring system in advance; S13. The long-term user uses the mobile terminal to forward through the cloud platform, sends a confirmation authorization instruction message to the elevator system, confirms the corresponding temporary user's elevator riding authority, and removes the restriction that the temporary user cannot call or take the elevator car during this ride; Steps S11-S13 can prevent unauthorized personnel from using the elevator system, thereby reducing carbon emissions; In this embodiment, it is further preferred that after the corresponding long-term user sends an operation to confirm the corresponding temporary user's elevator authority to the elevator system through the mobile terminal, the following steps may also be performed: S14, the carbon footprint measurement and control system marks the temporary user's elevator trajectory as the corresponding long-term user's elevator trajectory; step S14 can facilitate the statistics of actual carbon consumption related to the long-term user; S2. The visual recognition monitoring system obtains the set of elevator trajectories of each user within a set period of time in the past, and then sends it to the carbon footprint measurement and control system. The carbon footprint measurement and control system accordingly finds the data of various carbon footprint objects generated by the set of elevator trajectories of each user within the period, and then uses the carbon footprint algorithm for statistical analysis to obtain the carbon footprint data of each user at present; at the same time, all carbon footprint data are uploaded to the cloud platform; In this embodiment, the data of various carbon footprint objects generated by the elevator trajectory set during the time period are preferably the power consumption of various electrical devices from the elevator system, including but not limited to motors, electrical switches, microelectronic components, lighting fixtures, etc.; In this embodiment, the set period of time in step S2 can be set to 3 to 30 days or even longer; S3. Based on the carbon footprint data of all users acquired by the cloud platform in step S2, the carbon footprint measurement and control system counts the number of users who call the elevator system on different floors in different set time periods according to the carbon footprint data of all users, and uses the floor with the largest number of users as the base station in the corresponding set time period, and then sends a command message to the elevator system to start the base station function, and then the elevator system stops the elevator car at the floor corresponding to the base station in the corresponding set time period; In this embodiment, after obtaining the carbon footprint data of each current user through statistical analysis using the carbon footprint algorithm, the carbon footprint data of all users are analyzed by clustering statistics; the clustering labels include the floor used, different types of devices, etc.; In this embodiment, after the elevator system starts the base station function, the following steps can be performed: S31, the visual recognition monitoring system simultaneously identifies whether there is a user approaching the elevator system at the floor position passed during the current lifting process of the elevator car; S32, when the visual recognition monitoring system identifies that a user is approaching the elevator system, a selective waiting instruction message is sent to the elevator system, and then the elevator system controls the elevator car not to be lifted to other floors within a set period of time, so as to wait for the identified user to call the elevator car through the elevator system's call panel; S33. If the identified user does not call the elevator system within the set time period, or the lifting direction of the call is different from the lifting direction of the current elevator car, the elevator system controls the elevator car to lift to other floors to respond to other users; In this embodiment, the set time period of steps S32 and S33 can be set to 5 to 30 seconds, or a shorter time period; Steps S31-S33 can avoid the problem of increasing the carbon consumption of the elevator system due to the user missing the elevator car and having to re-operate the elevator car to his floor; S4, the carbon footprint measurement and control system performs fine control on various carbon consumptions of the elevator system according to the carbon footprint data of all users obtained in step S2; In this embodiment, the various carbon consumptions of the elevator system are preferably calculated starting from the 380V high-voltage input start section of the power box power supply of the elevator system, and the switch startup usage, power distribution, and micro-current flow of the electrical appliances inside the elevator system are counted, and the carbon footprint is divided according to the power size, and the energy of high-power devices and low-power devices is controlled at four levels; In this embodiment, the carbon footprint measurement and control system preferably has four levels of control over the elevator system as follows: (1) The first-level control is used for high-power devices such as control cabinet inverters and traction machines (380V power input), which can determine the opening or closing of the second-level control devices; the content of the first-level control is: setting the corresponding high-power device to open, corresponding to the operation of the main control cabinet, inverter, and traction machine; (2) Level 2 control is used for the opening and closing operation of the elevator door machine (220V power input), which can determine the opening or closing of the level 3 control device; the content of level 2 control is: setting the corresponding high-power device to open, corresponding to the operation of the elevator door machine; (3) The third-level control is used for the operation of the hall call panel, control box panel, car fan and lighting (24V power input), which can determine the opening or closing of the fourth-level control device; the content of the third-level control is: setting the bright display of the hall call panel to open, the control box panel of the elevator car, the car fan, and lighting fixtures to open; (4) Level 4 control is used for weak electronic devices (12V and below), such as the weak display of the hall call panel. The content of level 4 control is: set the hall call panel to open the weak display; Finely control the various carbon consumption of the elevator system. The specific steps are as follows: S41. When the elevator car is in operation: Turn on the first-level control full power and the second-level control full power to ensure the normal operation of the main control cabinet, inverter, traction machine, and elevator door machine; Level 3 control is activated according to 30% of the total carbon consumption of the elevator system, and level 4 control is activated according to 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 box panel of the elevator car, the car fan, and the lighting equipment are guaranteed to operate normally, and the external call panel of the non-service floor is operated with a weak display; S42. When the elevator car enters the standby state: the first-level control, second-level control, and third-level control are opened to enter the low-energy consumption mode according to 30% of the total carbon consumption of the elevator system, and the fourth-level control enters the screen-off state according to 10% of the power of the weak electronic device itself; S43, when the elevator car switches from the standby state to the running state, gradually turn on the four-level control, the three-level control, the two-level control, and the one-level control to restore to the fine control mode in step S41; S5. When executing steps S1-S4, the visual recognition monitoring system, the elevator system, and the carbon footprint measurement and control system all synchronously transmit the corresponding data and instruction records to the cloud platform for backup.

[0022] Compared with the prior art, the elevator control energy-saving method based on carbon footprint in this embodiment has the following beneficial effects: This embodiment can effectively reduce energy consumption and carbon emissions during the use of the elevator by performing energy-saving control on the elevator operation process, improve the elevator's passenger efficiency while avoiding excessive repeated operation of the elevator, and help extend the actual service life of the elevator.

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
