[0041] Figure 2 This is a schematic diagram of the structure of a crane control device provided in one embodiment of this application.

[0042] Figure 3 This is a schematic diagram of the structure of an electronic device provided in one embodiment of this application. Detailed Implementation

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] Existing cranes consume a significant amount of electricity, and keeping them in normal operation for extended periods often results in substantial power consumption. Conversely, prolonged periods of shutdown can lead to moisture damage to electrical components such as motors and outdoor cabinets. Therefore, reducing crane power consumption while preventing damage has become a major concern.

[0045] Embodiments of this application provide a crane control method, such as... Figure 1 As shown, the method may include at least the following steps:

[0046] Step S101: Detect whether the current time is during working hours.

[0047] Specifically, we can first check whether the current time is during working hours. By determining whether the current time is during working hours, we can provide a basis for reducing the power consumption of the crane in the future.

[0048] During implementation, working hours can be set according to actual needs; no restrictions are imposed here.

[0049] Step S102: If the current time is during working hours, determine the first duration of the crane; the first duration is the duration from the crane last receiving a work instruction to the current time.

[0050] In the embodiments of this application, the working state of the crane may include normal working state, standby state, and shutdown state.

[0051] If the current time falls within working hours, it indicates that the crane is in a relatively concentrated period of use, meaning it is in normal working condition. Since crane use may not be continuous, a first duration of inactivity can be monitored. If this first duration reaches a first threshold, it means the crane has been idle for an extended period. To save power, the crane can be put into standby mode; that is, after the first duration reaches the first threshold, the crane's operating state changes to standby. If the first duration does not reach the first threshold, it means the crane has not been idle for the required time, and its operating state remains normal.

[0052] Similarly, if the current time is not during working hours, it means the crane is not in use, and the crane can be controlled to enter a shutdown state. That is, keeping the crane in a shutdown state during non-working hours can further reduce power consumption and avoid damage to the electrical components in the crane by using lower power consumption.

[0053] Step S103: If the first duration meets the first threshold, then control the crane to enter the standby state and determine the second duration of the crane; the second duration is the duration of the crane in the standby state.

[0054] The first duration satisfying the first threshold means that the first duration reaches the first threshold. In implementation, the first threshold can be set according to actual needs, and is not limited here.

[0055] It should be noted that the power control of existing cranes can be divided into two parts: a mains power supply and an auxiliary power supply. Both the mains power supply and the auxiliary power supply are powered by AC mains electricity. Under normal operating conditions, AC mains electricity provides both the mains power and the auxiliary power; in standby mode, AC mains electricity stops supplying the mains power, providing only the auxiliary power; and in shutdown mode, AC mains electricity stops supplying both the mains power and the auxiliary power. In application, the mains power supply can refer to the power source that provides electricity to essential electrical components such as fans and motors for the normal operation of the crane; the auxiliary power supply refers to the power source that provides electricity to auxiliary electrical components such as controllers, air conditioners, and heaters to ensure the crane is not damaged.

[0056] By determining the second duration of the crane, the duration of the crane's current standby state can be determined, providing a basis for judging whether energy-saving control should be applied subsequently.

[0057] Step S104: If the second duration meets the second threshold, then control the crane to enter the shutdown state; wherein, the power consumption of the crane in the shutdown state is lower than the power consumption in the standby state.

[0058] The second duration satisfying the second threshold means that the second duration reaches the second threshold. Specifically, the specific value of the second threshold can be set according to actual needs and is not limited here.

[0059] Since the second duration is the duration during which the crane is in standby mode, the second duration begins to run after the crane enters standby mode. As time goes by, the second duration increases continuously. When the second duration during which the crane is in standby mode reaches the second threshold, it can be considered that the crane meets the conditions for entering the stop mode, and then the crane can be controlled to enter the stop mode from the standby mode.

[0060] It is important to understand that shutdown does not mean the crane is completely shut down. Even when the crane is in a shutdown state, the power supply to electrical components that cannot be disconnected must not be stopped. For example, heaters, emergency lights, and aviation lights need to remain operational.

[0061] In standby mode, the crane consumes less power but remains ready to enter normal operation at any time. For example, in standby mode, the crane's controller is still active and can continue to receive work commands. However, in shutdown mode, the crane consumes even less power, and its controller is in a non-power-consuming state, meaning it cannot receive work commands. In both states, protective devices (such as heaters) maintain normal operation to prevent damage to the crane's electrical components from moisture.

[0062] Since the power consumption of the crane in the stopped state is lower than that in the standby state, when the second duration meets the second threshold, it can be determined that the crane will not work for a relatively long period of time. Therefore, the crane can be controlled to enter the stopped state to further reduce the power consumption of the crane.

[0063] In this embodiment, the system first checks whether the current time is within working hours. If it is, a first duration for the crane is determined, which is the duration from the crane's last received work instruction to the current time. If the first duration meets a first threshold, the crane is controlled to enter a standby state, and a second duration is determined, which is the duration the crane remains in standby mode. If the second duration meets a second threshold, the crane is controlled to enter a stop state, where the power consumption in the stop state is lower than that in the standby state. This adds a stop state to the crane's working state, allowing it to enter a stop state after maintaining a standby state for the second duration, effectively reducing the crane's power consumption and achieving energy conservation.

[0064] In some embodiments, in order to further reduce the consumption of mains power, when controlling the crane to enter the shutdown state, the target electrical device corresponding to the shutdown state can be determined first based on the pre-stored correspondence between the working state and the crane's electrical components; then the current power supply equipment is switched to the target energy storage device so that the target energy storage device supplies power to the target electrical device.

[0065] In implementation, a correspondence between working states and crane electrical components can be established first (for example, the normal working state corresponds to all electrical components in the crane), and a target energy storage device can be pre-set. Then, based on the correspondence between working states and crane electrical components, the electrical components corresponding to the shutdown state can be identified, and the current power supply equipment can be switched to the target energy storage device to stop the current power supply equipment from continuing to provide power and instead utilize the target energy storage device to provide power.

[0066] In practice, current power supply equipment is generally powered by mains electricity. Therefore, any energy storage device can be used when setting up the target energy storage device. Preferably, the target energy storage device can store green, high-quality energy (wind power, solar power, etc.). That is, solar energy storage devices, wind energy storage devices, and other green energy storage devices can be used as power supply equipment when the crane is not in operation, thereby reducing mains power consumption and achieving energy conservation and emission reduction.

[0067] Among them, the target energy storage device can have an early warning function. When the power in the target energy storage device is lower than the fourth threshold, it can be considered that the power in the target energy storage device is insufficient, and an alarm can be issued to avoid the inability to maintain the shutdown state of the crane due to insufficient power.

[0068] Of course, when the target energy storage device is low on power, the device can be shut down to supply power to the crane, and the mains power can be used instead to keep the crane in a standby state.

[0069] In some embodiments, after determining the second duration of the crane, the crane control method may further include: if the second duration does not meet the second threshold, detecting whether the crane has received a work instruction; if the crane has received a work instruction, controlling the crane to enter a normal working state.

[0070] Specifically, during the timing of the second duration, it is possible to detect in real time whether the crane has received a work instruction. If the crane has received a work instruction before the second duration reaches the second threshold, it indicates that the crane is working actively, and the crane's working state can be restored to normal working state so that the work instruction sent by the user can be executed.

[0071] Since a crane cannot receive work instructions after entering a shutdown state, in order to avoid affecting the crane's subsequent work and causing inconvenience to the user by automatically controlling the crane to enter a shutdown state, in some embodiments, the crane control method may further include: sending a shutdown query to a client and recording the duration of the query; detecting whether a feedback instruction from the client in response to the shutdown query is received before the duration of the query reaches a third threshold; if no feedback instruction from the client in response to the shutdown query is received, then proceeding to the next step; if a feedback instruction from the client in response to the shutdown query is received, then controlling the crane to perform the corresponding operation according to the feedback instruction.

[0072] The fourth threshold can be set according to actual needs, and is not limited here.

[0073] Therefore, before controlling the crane to enter a shutdown state, the user can be notified of the crane's current operating status by sending a query, allowing the user to decide whether to control the crane to enter a shutdown state. This avoids controlling the crane to a shutdown state without the user's knowledge, thus preventing disruption to the user's use of the crane.

[0074] In some embodiments, the crane control method may further include: acquiring control commands sent by a user; determining the working state to be entered based on the control commands; and controlling the crane to enter the working state.

[0075] In application, users can control the crane's operating status according to their needs. For example, if the crane is currently in a stopped state, when the user needs to use the crane, they can send a control command to start the crane via the client to the crane's control equipment. The crane's control equipment can then determine the normal operating state based on the received control command and control the crane to enter that state. This provides greater convenience for users.

[0076] As another optional implementation of this application, embodiments of this application also provide a crane control device, such as... Figure 2 As shown, the device may include: a detection module 201, used to detect whether the current time is within working hours; a determination module 202, used to determine a first duration of the crane if the current time is within working hours; the first duration is the duration from the crane's last receipt of a work instruction to the current time; a control and determination module 203, used to control the crane to enter a standby state if the first duration meets a first threshold, and to determine a second duration of the crane; the second duration is the duration of the crane in the standby state; and a control module 204, used to control the crane to enter a stop state if the second duration meets a second threshold; wherein the power consumption of the crane in the stop state is lower than the power consumption in the standby state.

[0077] Optionally, the control module 204 can also be used to: control the crane to enter a stop state if the current time is not during working hours.

[0078] Optionally, when the crane is controlled to enter the shutdown state, the control module 204 may be used to: determine the target electrical device corresponding to the shutdown state based on the pre-stored correspondence between the working state and the crane's electrical devices; and switch the current power supply equipment to the target energy storage device so that the target energy storage device supplies power to the target electrical device.

[0079] Optionally, the crane control device may further include a detection and control module, which may be used to: detect whether the crane has received a work instruction if the second duration does not meet the second threshold; and control the crane to enter normal working state if the crane has received a work instruction.

[0080] Optionally, the crane control device may further include an inquiry module, which can be used to: send a shutdown inquiry to the client and record the duration of the inquiry; detect whether a feedback instruction from the client in response to the shutdown inquiry is received before the duration of the inquiry reaches a third threshold; if no feedback instruction from the client in response to the shutdown inquiry is received, then proceed with the subsequent steps; if a feedback instruction from the client in response to the shutdown inquiry is received, then control the crane to perform the corresponding operation according to the feedback instruction.

[0081] Optionally, the crane control device may further include an acquisition and control module, which can be used to: acquire control commands sent by the user; determine the working state to be entered according to the control commands, and control the crane to enter the working state.

The second duration is the duration during which the crane is in the standby state; The control module is configured to control the crane to enter a shutdown state if the second duration meets a second threshold. Before controlling the crane to enter the shutdown state, a shutdown query is sent to a client, and the duration of the query is recorded. The module detects whether a feedback instruction from the client in response to the shutdown query is received before the duration reaches a third threshold. If no feedback instruction is received, subsequent steps are executed. If a feedback instruction is received, the crane is controlled to perform a corresponding operation based on the feedback instruction. The power consumption of the crane in the shutdown state is lower than that in the standby state. The power consumption under the specified state; the control of the crane to enter the shutdown state includes: determining the target electrical device corresponding to the shutdown state based on the pre-stored correspondence between the working state and the crane's electrical components; switching the current power supply equipment to the target energy storage device so that the target energy storage device supplies power to the target electrical device; the target energy storage device includes solar or wind energy storage devices; and, if the current time is not during working hours, controlling the crane to enter the shutdown state; when the power in the target energy storage device is lower than a fourth threshold, issuing an alarm prompt and stopping the use of the target energy storage device to supply power to the crane, and switching to mains power to maintain the crane's shutdown state.
