[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0023] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0024] In related technologies, maintenance personnel typically inspect and operate elevators using a handheld / fixed inspection device mounted on the car top, controlling the elevator's movement via three buttons (Up, Run, Down). When the maintenance personnel press both the "Up" and "Run" buttons simultaneously, the elevator moves upward; when they press both the "Down" and "Run" buttons simultaneously, the elevator moves downward. This control method has at least the following problems: 1. Regardless of whether the elevator is traveling a long or short distance, it operates at a fixed speed. However, this can lead to inconveniences during actual installation and maintenance. For example, when long-distance maintenance is required, the elevator speed needs to be increased appropriately; conversely, when troubleshooting, the elevator speed needs to be reduced.

[0025] 2. The installation positions of components such as the hoistway magnetic shielding plate and limit switches are determined based on civil engineering parameters and can be calculated in advance. When maintenance personnel install these components, since current elevator maintenance and operation are entirely based on manual judgment, it is inevitable that the elevator will not be moved to the correct position or will move beyond the installation location, resulting in multiple adjustments to the elevator's operation.

[0026] 3. When maintenance personnel are performing maintenance inside the hoistway, there are several particularly dangerous locations, such as: near the upper and lower terminal stations, and where the counterweight and car intersect. Currently, there are no special warnings for these locations, and maintenance personnel must rely on their own judgment.

[0027] Based on the above, embodiments of the present invention provide an elevator maintenance control method, device, electronic equipment, and storage medium, which can effectively alleviate the above-mentioned technical problems.

[0028] Please refer to Figure 1 This is a block diagram of an electronic device 100 provided in this application. The electronic device 100 can be a data processing device, and this embodiment does not limit this. The electronic device 100 includes a memory 110, a processor 120, and a communication module 130. The memory 110, processor 120, and communication module 130 are electrically connected directly or indirectly to achieve data transmission or interaction. For example, these components can be electrically connected to each other through one or more communication buses or signal lines.

[0029] The memory 110 is used to store programs or data. The memory 110 may be, but is not limited to, random access memory (RAM), read-only memory (ROM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), etc.

[0030] The processor 120 is used to read / write data or programs stored in memory and to perform corresponding functions.

[0031] The communication module 130 is used to establish a communication connection between the server and other communication terminals through the network, and to send and receive data through the network.

[0032] It should be understood that, Figure 1 The structure shown is only a schematic diagram of the electronic device 100. The electronic device 100 may also include components that are larger than... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown. Figure 1The components shown can be implemented using hardware, software, or a combination thereof. This electronic device 100 can be integrated into other devices or configured as a standalone device.

[0033] This invention provides an elevator maintenance control method, applied to an elevator controller, wherein the elevator controller is communicatively connected to a command terminal. The method includes, for example: Figure 2 The following steps are shown: Step S110: When the elevator is under maintenance, receive the elevator control command sent by the command terminal.

[0034] Step S120: Parse the elevator control command, and after receiving the elevator operation command sent by the command terminal, control the elevator operation state based on the elevator control command. The operation state includes the running direction and the running speed.

[0035] In step S110, when the elevator is under maintenance, the elevator control command sent by the command terminal is received.

[0036] The maintenance status refers to the specific operating mode of the elevator when maintenance personnel enter the hoistway and perform maintenance on the car top. The command terminal can be a handheld or fixed maintenance device on the car top, such as a remote control with multiple buttons. Maintenance personnel issue commands to the elevator controller via the command terminal by pressing the buttons. When the elevator is in maintenance status, the elevator controller receives elevator control commands sent by the command terminal. For example, by pressing the "up" button on the command terminal, maintenance personnel send an upward elevator control command to the elevator controller.

[0037] In step S120, the elevator control command is parsed, and after receiving the elevator operation command sent by the command terminal, the elevator operation status is controlled based on the elevator control command. The operation status includes the running direction and the running speed.

[0038] Upon receiving an elevator control command, the elevator controller parses the received command and, upon receiving an elevator operation command from the command terminal, controls the elevator's operating status based on the parsed command. This operating status can specifically include the direction of travel and the speed of travel.

[0039] For example, maintenance personnel can set the required speed or direction parameters through the command terminal before or during maintenance work. After the parameters are set and the running command is issued again, the elevator controller will control the elevator to run according to the preset parameters, avoiding the tedious operation of continuously pressing buttons during operation.

[0040] Optionally, the elevator control command includes a speed adjustment command, which includes a first-speed adjustment command and a second-speed adjustment command. The first speed corresponding to the second-speed adjustment command is different from the second speed corresponding to the first-speed adjustment command. Controlling the elevator's operating state based on the elevator control command includes: Receive the speed adjustment command.

[0041] If the speed adjustment command is the first speed adjustment command, control the elevator to run at the first speed.

[0042] If the speed adjustment command is the second speed adjustment command, the elevator is controlled to run at the second speed.

[0043] Elevator control commands may include speed adjustment commands, which may further include first-speed adjustment commands and second-speed adjustment commands, wherein the first speed corresponding to the second-speed adjustment command is different from the second speed corresponding to the first-speed adjustment command. When controlling the elevator's operating state based on elevator control commands, the elevator controller receives a speed adjustment command. If the speed adjustment command is determined to be a first-speed adjustment command, the elevator is controlled to run at the first speed. If the speed adjustment command is determined to be a second-speed adjustment command, the elevator is controlled to run at the second speed.

[0044] Specifically, the speed can be adjusted in multiple levels by setting a speed control knob on the command terminal. For example, when long-distance maintenance is required, maintenance personnel can select a faster speed to make the elevator run at a higher speed, thereby improving work efficiency. When detailed troubleshooting is required, a lower speed than the elevator's basic operating speed can be selected to make the elevator move at a slower and smoother speed, making it easier for maintenance personnel to observe and make judgments.

[0045] Optionally, the elevator control command includes a distance setting command, and controlling the elevator's operating state based on the elevator control command includes: Receive the distance setting command.

[0046] The elevator's current position is determined based on the elevator's position detection device.

[0047] The target location that the elevator needs to reach is determined based on the current location and the target distance in the distance setting instruction.

[0048] The elevator is controlled to move toward the target position, and the current position is updated in real time through the position detection device until the updated current position is the target position, at which point the elevator is controlled to stop moving.

[0049] like Figure 3The diagram shows a schematic of a command terminal. When the maintenance personnel press the "STOP" button, the elevator controller stops the elevator. Pressing both the "RUN" and "UP" / "DN" buttons simultaneously issues a command to run the elevator. When the maintenance personnel rotate the knob, the elevator controller controls the elevator to run at the speed indicated by the pointer. Distance setting can be done in two ways: First, four LED indicators can be used, corresponding to m / dm / cm / mm respectively, with values ​​set via "+" and "-" buttons to allow the elevator controller to determine the target position. Second, a digital display can be used to show the set distance, with "shift" and "add / subtract" buttons for setting the distance value.

[0050] In another optional implementation, the elevator control commands may include distance setting commands. When controlling the elevator's operation based on these commands, the elevator controller receives the distance setting command and determines the elevator's current position using a position detection device installed on the elevator. This position detection device can be a standard elevator component such as a rotary encoder, magnetic scale, or optical scale, used to detect the elevator's precise position in the shaft in real time. The elevator controller then determines the target position the elevator needs to reach based on the current position and the target distance specified in the distance setting command.

[0051] For example, if the elevator car is currently on a certain floor, and maintenance personnel set a target distance of 2 meters upwards via a command terminal, the elevator controller will calculate the target position as the coordinates 2 meters above the current position. The elevator controller then controls the elevator to move towards the target position, updating the current position in real time via a position detection device until the updated current position matches the target position, at which point the elevator stops. This method achieves automatic setting of the elevator's travel distance and precise stopping, avoiding the need for multiple adjustments due to manual judgment in traditional maintenance methods. It is particularly suitable for scenarios where components such as magnetic shielding plates and limit switches within the shaft require precise installation based on civil engineering parameters.

[0052] Optionally, the method further includes: If the direction of the elevator movement command is opposite to the direction in which the elevator moves from its current position to the target position, then the elevator is controlled to stop moving.

[0053] If, during the process of controlling the elevator to move from the current position to the target position, an elevator operation cancellation command is received from the command terminal, the elevator is controlled to pause its movement, and upon receiving the elevator operation command again, the elevator is controlled to continue moving towards the target position.

[0054] During maintenance at the set distance, to address potential operational interruptions or misoperations, if the direction the elevator's operating command indicates is opposite to the direction from the current position to the target position, the elevator controller will stop the elevator. If, during the movement of the elevator from the current position to the target position, the elevator controller receives an elevator operation cancellation command from the command terminal, it will pause the elevator's movement and resume movement towards the target position upon receiving a new elevator operating command.

[0055] For example, if a maintenance worker accidentally issues a downward command while the elevator is moving upwards towards its target location, the elevator controller will immediately stop the current movement to prevent the elevator from deviating from the preset target. As another example, if a maintenance worker indirectly controls the elevator via a command terminal (e.g., by simultaneously pressing the "Run" and "Up" buttons), and accidentally releases the "Run" and / or "Up" buttons due to hand fatigue, this is equivalent to issuing a cancellation command to the elevator controller. The controller will then pause the elevator's movement until the maintenance worker presses the "Run" and "Up" buttons again to resume movement.

[0056] Optionally, the method further includes: If a power outage occurs during the process of moving the elevator from its current position to the target position.

[0057] The position of the elevator determined by the position detection device at the moment of power failure is saved, and the elevator is controlled to stop moving.

[0058] After power is restored and the elevator operation command is received, the elevator is controlled to continue moving towards the target location.

[0059] Considering the potential for unstable power supply at elevator maintenance sites, if a power outage occurs while the elevator is moving from its current position to the target position, the elevator controller will save the elevator position determined by the position detection device at the moment of power failure and stop the elevator. Once power is restored, the elevator controller will resume movement to the target position upon receiving the elevator operation command again. By saving the elevator position before the power outage, the elevator can resume its unfinished distance-setting operation from the point of interruption after power is restored, eliminating the need for maintenance personnel to reset the distance or perform position calibration, thereby improving the continuity and reliability of maintenance work.

[0060] Optionally, an alarm is installed on the elevator, and the alarm is communicatively connected to the elevator controller. The method further includes: The elevator's real-time position is obtained based on the elevator's position detection device.

[0061] When the elevator moves to a preset distance from the preset point, the alarm will sound an alarm.

[0062] To further enhance the safety of maintenance operations, an alarm device that communicates with the elevator controller can be installed on the elevator. The elevator controller obtains the real-time position of the elevator based on the elevator's position detection device. When the elevator moves to a preset distance from a preset point, it controls the alarm device to emit an alarm sound.

[0063] For example, when the elevator is 1.5 meters away from the upper station, the alarm will automatically issue a voice prompt to alert maintenance personnel in the shaft to pay attention to safety. This effectively compensates for the shortcomings of traditional maintenance methods that rely solely on maintenance personnel's own judgment for safety.

[0064] Optionally, the preset points include the upper elevator station, the lower elevator station, and the counterweight location.

[0065] During maintenance operations within the elevator shaft, several locations present particular risks. The upper and lower stations are the physical endpoints of the shaft, posing a risk of mechanical overshoot or undershoot. While elevator shafts typically have buffers at the top and bottom, their purpose is to absorb energy from unexpected overtravel, not for normal operation. When maintenance operations approach the upper station, the space between the car and the shaft ceiling narrows dramatically, making it extremely easy for maintenance personnel standing on the car top to suffer head injuries or collisions. Similarly, near the lower station, the distance between the car bottom and the pit disappears. If the elevator continues to descend due to inertia or operational error, it may directly impact the buffers, causing personnel standing on the car top to lose balance and fall due to the violent vibration.

[0066] The counterweight involves the intersection of a high-speed moving counterweight and the work area. The counterweight is a metal block used to balance the weight of the elevator car, moving relative to the car within the hoistway. When the car is in the upper part of the hoistway, the counterweight is in the lower part, and vice versa. During maintenance, if the car moves to an area level with the counterweight, the counterweight will appear to the side or directly opposite the car. Because the counterweight block usually lacks a complete protective cover, and its trajectory overlaps with the car, maintenance personnel who reach or lean out from the car roof are highly susceptible to being sheared or struck by the high-speed counterweight, causing serious personal injury. Therefore, the upper and lower elevator stations, as well as the counterweight's location, can be set as preset points.

[0067] Based on the same inventive concept, such as Figure 4 As shown in the figure, an embodiment of the present invention provides an elevator maintenance control device 300, which is applied to an elevator controller. The elevator controller is communicatively connected to a command terminal. The elevator maintenance control device 300 includes: The control command receiving unit 301 is used to receive elevator control commands sent by the command terminal when the elevator is under maintenance.

[0068] The operation status control unit 302 is used to parse the elevator control command and, after receiving the elevator operation command sent by the command terminal, control the operation status of the elevator based on the elevator control command. The operation status includes the running direction and the running speed.

[0069] Regarding the elevator maintenance control device 300 mentioned above, the specific functions of each unit have been described in detail in the embodiments of the elevator maintenance control method provided in this specification, and will not be elaborated here.

[0070] Based on the same inventive concept, embodiments of this invention provide a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of any of the methods of the elevator maintenance control method described above.

[0071] The present invention has at least the following beneficial effects: 1. By receiving elevator control commands from the command terminal, and after parsing the elevator control commands and receiving elevator operation commands again from the command terminal, the elevator's running direction and speed are controlled based on the elevator control commands. This allows the elevator to run at a matching speed under different speed requirements, improving maintenance efficiency.

[0072] 2. By using distance setting commands, the elevator controller can stop the elevator at a precise location, avoiding the need for maintenance personnel to repeatedly control the elevator to move to a certain position.

[0073] 3. By installing alarms, maintenance personnel are promptly alerted to safety when the elevator approaches certain dangerous locations, thus improving the safety of maintenance work.
