Therefore, the features limited by "first", "second" can be explicitly or implicitly included at least one of the features.

[0055] The confirmation of the real-time height of the tower crane is one of the important data for the tower crane to ensure the safety of the operation and ensure the realization of the function. Since the tower crane completes the lifting of the height by adding and subtracting the standard section, the application embodiments complete the determination and update of the height of the tower crane by judging the adding and subtracting of the standard section of the tower crane.

[0056] Figure 1 The flowchart of a tower crane height determination method according to the application embodiments is shown, as shown in Figure 1 In one embodiment of the application, a tower crane height determination method is provided, comprising steps S100-S400.

[0057] Step S100: Obtain the hook-up position, hook-down position and lifting weight of the tower crane hook.

[0058] The hook-up position of the tower crane hook is the position of the hook when the heavy object is lifted onto the hook, the hook-down position is the position of the hook when the heavy object is lowered from the hook, and the lifting weight is the weight of the heavy object lifted by the hook, which remains unchanged throughout the lifting process. The above hook-up position, hook-down position and lifting weight are the basis for determining whether the tower crane completes the standard section adding and subtracting process.

[0059] In one embodiment of the application, the hook-up position, hook-down position and lifting weight of the tower crane hook are obtained (step S100), comprising:

[0060] Step S110: Real-time obtain the current lifting height, current rotation angle, current amplitude and current lifting weight of the tower crane;

[0061] Step S120: determining the hook-up position and the hook-down position according to the current lifting height, the current slewing angle, the current luffing angle and the current load weight;

[0062] Step S130: determining the lifting weight according to the current load weight when the hook is in the hook-up position.

[0063] The hook-up position, the hook-down position and the lifting weight of the hook need to be determined according to the current lifting height, the current slewing angle, the current luffing angle and the current load weight of the tower crane. The processor acquires the current lifting height, the current slewing angle, the current luffing angle and the current load weight of the tower crane in real time. It can be understood by those skilled in the art that the current load weight acquired by the processor in real time is 0 after the heavy object is put down from the hook and when the hook does not carry the heavy object. Specifically, when the current load weight acquired by the processor changes from 0 to a value greater than 0, the position of the hook at this time is determined according to the acquired current lifting height, the current slewing angle and the current luffing angle, which is the hook-up position, and the current load weight of the hook when the hook is in the hook-up position is the lifting weight; when the current load weight acquired by the processor changes from a value greater than 0 to 0, the position of the hook at this time is determined according to the acquired current lifting height, the current slewing angle and the current luffing angle, which is the hook-down position.

[0064] In an embodiment of the present application, the current lifting height, the current slewing angle, the current luffing angle and the current load weight of the tower crane are acquired in real time, including:

[0065] The current lifting height is acquired in real time by the lifting encoder;

[0066] The current slewing angle is acquired in real time by the slewing encoder;

[0067] The current luffing angle is acquired in real time by the luffing encoder;

[0068] The current load weight is acquired in real time by the weight sensor.

[0069] Figure 2 A device position schematic diagram of a parameter detection device according to an embodiment of the present application is shown, as shown in FIG. 1. Figure 2As shown, the various parameters of the tower crane (current lifting height, current slewing angle, current luffing, and current load weight) can be directly obtained through parameter detection devices arranged at various locations on the tower crane. Specifically, the current lifting height is obtained in real time through a lifting encoder arranged at the lifting motor (position 1) on the counterweight boom; the current slewing angle is obtained in real time through a slewing encoder arranged at the slewing motor (position 2); the current luffing is obtained in real time through a luffing encoder arranged at the luffing motor (position 3) near the boom root; and the current load weight is obtained through a weight sensor arranged at the boom root (position 4). Those skilled in the art will understand that the lifting encoder, slewing encoder, luffing encoder, and weight sensor are all conventional devices found in tower crane electrical control systems. The processor that completes the tower crane height determination method provided in this application embodiment can also be directly set as the main controller itself in the tower crane operator's cab (position 5). That is, the tower crane height determination method provided in this application embodiment does not require the use of third-party equipment for parameter detection or data processing, thus avoiding additional hardware costs.

[0070] Step S200: Determine the tower crane's work task type based on the hook-lifting position, hook-lowering position, and lifting weight.

[0071] Figure 3 A schematic diagram illustrating the process of a tower crane lifting a standard section according to an embodiment of this application is shown, such as... Figure 3 As shown, tower cranes need to be raised or lowered through a jacking process. Taking the raising process as an example, the raising process requires adding a standard section. First, by controlling the jacking cylinder, a part of the tower crane is raised, dividing the tower crane into two parts to create space for introducing a new standard section. This raises the tower crane, and the standard section A is hoisted from another position into the introduction surface S before being unloaded. The lowering process is the opposite of the raising process, requiring removing a standard section. After the tower crane removes the standard section, the hook lifts the standard section from the introduction surface and unloads it to another position. Therefore, whether it is the hook lowering during standard section addition or the hook raising during standard section removal, it is located in a specific space above the introduction surface, namely the standard section introduction area M. The specific range and size of the standard section introduction area can be reasonably set through multiple tests, and this application does not impose any limitations on it.

[0072] During the process of adding or subtracting standard sections of a tower crane, not only is the position of the tower crane hook special, but the lifting weight of the hook is also special. That is, during the process of adding or subtracting standard sections of a tower crane, the lifting weight is always the weight of a single standard section.

[0073] Based on the special characteristics of the hook-up position, hook-down position, and lifting weight, the processor can determine whether the tower crane's work task type is related to the addition or subtraction of standard sections once it obtains the hook-up position, hook-down position, and lifting weight.

[0074] In an embodiment of the present application, the work task type includes standard section adding section, standard section reducing section, standard section moving, and other tasks, and the work task type of the tower crane is determined according to the hook-up position, the hook-down position, and the lifting weight (step S200), including:

[0075] Step S210: in the case where the lifting weight is not the weight of a single standard section, the work task type is determined to be other tasks;

[0076] Step S220: in the case where the lifting weight is the weight of a single standard section, the work task type is determined to be one of standard section adding section, standard section reducing section, and standard section moving according to the hook-up position and the hook-down position.

[0077] Figure 4 A flow logic diagram of a tower crane height determination method according to an embodiment of the present application is shown, please refer to Figure 1 、 Figure 3 and Figure 4 , the processor acquires the current lifting height, the current rotation angle, the current luffing, and the current lifting load weight, after the hook-up position and the lifting weight of the hook are determined, firstly, it is judged whether the lifting weight is the weight of a single standard section, if the lifting weight is not the weight of a single standard section, it is indicated that the hook does not lift a standard section, i.e. the work task type of the tower crane is other tasks irrelevant to the standard section lifting; in the case where the lifting weight is the weight of a single standard section, it can be determined that the work task type of the tower crane is a task type related to the standard section lifting, i.e. the work task type of the tower crane is one of standard section adding section, standard section reducing section, and standard section moving. At this time, the hook-up position is recorded, which is used for determining the work task type of the tower crane in combination with the hook-down position in the future, and the work task type is one of standard section adding section, standard section reducing section, and standard section moving.

[0078] In an embodiment of the present application, in the case where the lifting weight is the weight of a single standard section, the work task type is determined to be one of standard section adding section, standard section reducing section, and standard section moving according to the hook-up position and the hook-down position (step S220), including:

[0079] Step S221: if the hook-up position is outside the standard section introduction area, and the hook-down position is inside the standard section introduction area, the work task type is determined to be standard section adding section;

[0080] Step S222: if the hook-up position is inside the standard section introduction area, and the hook-down position is outside the standard section introduction area, the work task type is determined to be standard section reducing section;

[0081] Step S223: If the hook-up position and the hook-down position are both outside the standard section introduction area or both inside the standard section introduction area, the work task type is determined as standard section movement.

[0082] If the current load weight obtained by the processor is 0, it indicates that the hook has completed unloading, and the position at this time is recorded as the hook-down position. The hook-up position and the hook-down position are combined to determine the work task type.

[0083] If the hook-up position is outside the standard section introduction area and the hook-down position is inside the standard section introduction area, it indicates that the hook has introduced the standard section from other positions into the standard section introduction area, i.e., the tower crane has performed a standard section adding process, and the processor determines the work task type as standard section adding. If the hook-up position is inside the standard section introduction area and the hook-down position is outside the standard section introduction area, it indicates that the hook has carried the standard section from the standard section introduction area to other positions, i.e., the tower crane has performed a standard section reducing process, and the processor determines the work task type as standard section reducing. If the hook-up position and the hook-down position are both outside the standard section introduction area, i.e., the hook has not carried the standard section in the introduction area, or the hook-up position and the hook-down position are both inside the standard section introduction area, i.e., the hook has not moved the standard section beyond the range of the standard section introduction area, therefore, if the hook-up position and the hook-down position are both outside the standard section introduction area or both inside the standard section introduction area, i.e., the tower crane has not performed a standard section adding or reducing process, the processor determines the work task type as standard section movement.

[0084] In an embodiment of the present application, the method further comprises:

[0085] Step S230: determining the type of other tasks according to the hook-up position and the hook-down position.

[0086] The processor can further determine the specific type of other tasks according to the hook-up position and the hook-down position.

[0087] In an embodiment of the present application, the other tasks include a general hoisting object, hoisting object tower-up, hoisting object tower-down, and hoisting object position fine adjustment, and determining the type of other tasks according to the hook-up position and the hook-down position (step S230) comprises:

[0088] Step S231: if the hook-up position is outside the standard section introduction area and the hook-down position is outside the standard section introduction area, determining the work task type as a general hoisting object.

[0089] Step S232: if the hook-up position is outside the standard section introduction area and the hook-down position is inside the standard section introduction area, determining the work task type as hoisting object tower-up.

[0090] Step S233: If the hook-up position is in the standard section introduction area and the hook-down position is out of the standard section introduction area, the work task type is determined as lifting the load down the tower;

[0091] Step S234: If the hook-up position and the hook-down position are both in the standard section introduction area, the work task type is determined as fine adjustment of the position of the load.

[0092] Other task types are work tasks of lifting a hook without a standard section, if the hook-up position is out of the standard section introduction area and the hook-down position is out of the standard section introduction area, i.e. the hook lifts the load to move out of the standard section introduction area, the processor determines the work task type as normal lifting of the load; if the hook-up position is out of the standard section introduction area and the hook-down position is in the standard section introduction area, i.e. the hook lifts the load from other positions to the standard section introduction area, the processor determines the work task type as lifting the load up the tower; if the hook-up position is in the standard section introduction area and the hook-down position is out of the standard section introduction area, i.e. the hook lifts the load from the standard section introduction area to other positions, the processor determines the work task type as lifting the load down the tower; if the hook-up position and the hook-down position are both in the standard section introduction area, i.e. the hook lifts the load to move in a small range in the standard section introduction area, the processor determines the work task type as fine adjustment of the position of the load.

[0093] Step S300: determining the standard section addition and subtraction of the tower crane according to the work task type;

[0094] After the processor determines the work task type, the standard section addition and subtraction of the tower crane can be determined according to whether the work task type involves the standard section addition and subtraction process.

[0095] In an embodiment of the present application, the determination of the standard section addition and subtraction of the tower crane according to the work task type (step S300) comprises:

[0096] In the case of other tasks or standard section movement, it is determined that the number of standard sections of the tower crane does not change;

[0097] In the case of standard section addition, it is determined that the tower crane has added a single standard section;

[0098] In the case of standard section subtraction, it is determined that the tower crane has subtracted a single standard section.

[0099] In the case of other tasks or standard section movement, the tower crane does not perform the standard section addition and subtraction process, and the processor determines that the number of standard sections of the tower crane does not change; in the case of standard section addition, the tower crane performs the standard section addition process, and the processor determines that the tower crane has added a single standard section; in the case of standard section subtraction, the tower crane performs the standard section subtraction process, and the processor determines that the tower crane has subtracted a single standard section.

[0100] Step S400: determining the height of the tower crane according to the adding or subtracting condition of the standard section.

[0101] The adding or subtracting condition of the standard section of the tower crane can be directly used to determine or update the height of the tower crane. If the number of the standard sections of the tower crane does not change, that is, the height of the tower crane does not change, if the tower crane has added a single standard section, the height of the tower crane is increased by a height of a single standard section based on the current height, if the tower crane has subtracted a single standard section, the height of the tower crane is decreased by a height of a single standard section based on the current height. Exemplarily, the initial height of the tower crane and the height of a single standard section can be initialized and stored in the memory in advance, so that the processor can be called to process data.

[0102] By the tower crane height determination method in the above embodiment, the tower crane hook position particularity and the hoisting weight particularity in the adding or subtracting process of the standard section of the tower crane are relied on, the hook-up position, the hook-down position and the hoisting weight of the hook are acquired, the working task type of the tower crane can be determined, then according to the working task type, it is judged whether the adding or subtracting process of the standard section of the tower crane is completed, so that the height of the tower crane can be accurately and timely determined or updated. In this way, the height of the tower crane does not need to be determined manually, manually input, nor needs to be measured and confirmed by adding a third party height measuring device, so that the inaccuracy of manual determination and the untimeliness of manual input are avoided, and the confirmation of the height of the tower crane is more economical and convenient.
