Fig. 1 is a schematic structural view illustrating a display device for a crane according to some embodiments of the present disclosure.
As shown in fig. 1, the display device may include an acquisition unit 101, an information processing unit 102, and a display unit 103.
The obtaining unit 101 is configured to obtain a performance parameter table for the crane and current actual operating condition data of the crane. The data in the performance parameter table may include: multiple sets of operating condition data, and multiple sets of display data corresponding to each set of operating condition data. Each set of display data may include a desired boom amplitude and a maximum hoist height corresponding to the desired boom amplitude.
Here, the boom amplitude refers to the horizontal distance from the center of rotation or the center of a fixed column of a movable arm or a fixed arm of the crane to the center of the hook. The boom amplitude may be a component of the boom length in the horizontal direction. The maximum hoisting height corresponding to a desired boom amplitude can be understood as the maximum height to which a hoisting object corresponding to the desired boom amplitude can be raised.
In some embodiments, the plurality of sets of operating condition data in the performance parameter table may include: the arm length (the length of the suspension arm), the multiplying power of a steel wire rope, the boom extension combination data, the telescopic state of the supporting legs and the like of the crane. Here, the wire rope multiplying power can be understood as the number of wire ropes borne by the movable pulley block. The boom combination data may include: percentage of each arm extending. The leg telescoping state may include, for example: fully extended support legs, half extended support legs and the like.
In some embodiments, current operating condition data may be measured by sensors. For example, the current arm length of the boom can be measured by a length sensor. For example, the current boom combination data may be calculated by in-boom length measurement sensor measurements. For example, the telescopic state of the support leg can be set by manually selecting a button, and can also be obtained by measuring and calculating by a support leg length measuring sensor. The respective sensor may transmit the measured data to the acquisition unit 101. In some embodiments, the wire rope magnification may be input by manual input, so that the obtaining unit 101 obtains the wire rope magnification.
For example, table 1 schematically shows a performance parameter table of a crane. As can be seen from this performance parameter table 1. The performance parameter table 1 may include multiple sets of operating condition data, for example, 3 sets of operating condition data 1, 2, and 3. For example, the first set of operating condition data 1 includes: the crane comprises data such as arm length 1, steel wire rope multiplying power 1, boom combination data 1 and leg stretching state 1. The performance parameter table 1 may further include a plurality of sets of display data corresponding to each set of operating condition data. For example, 3 sets of display data correspond to the first set of operating condition data 1, 3 sets of display data correspond to the second set of operating condition data 2, and 3 sets of display data correspond to the third set of operating condition data 3.
Each set of display data may include a desired boom amplitude and a maximum hoist height corresponding to the desired boom amplitude. For example, in 3 sets of display data corresponding to the first set of operating condition data 1, the first set of display data includes a desired boom amplitude 11 and a maximum lift height 11 ' corresponding to the desired boom amplitude 11, the second set of display data includes a desired boom amplitude 12 and a maximum lift height 12 ' corresponding to the desired boom amplitude 12, and the third set of display data includes a desired boom amplitude 13 and a maximum lift height 13 ' corresponding to the desired boom amplitude 13. Other display data are similar and are not described in detail herein.
TABLE 1 exemplary Crane Performance parameter Table
It should be noted that table 1 is merely exemplary. The data in the performance parameter table of the disclosed embodiments may be obtained according to known techniques. Those skilled in the art will appreciate that the performance parameter tables of the embodiments of the present disclosure can be determined according to actual needs or actual situations, and therefore, the performance parameter tables of the embodiments of the present disclosure are not limited thereto.
The information processing unit 102 is configured to search a set of display data corresponding to the current actual operating condition data from the performance parameter table in the first mode. In the first mode, the handle of the crane is not actuated. For example, no handle actuation means that the handle is in a neutral position. For example, for an electric control vehicle, the handle sends information through a bus signal, so that the position of the handle can be judged through the bus signal.
In some embodiments, the following specific implementation may be adopted to find a set of display data corresponding to the current actual operating condition data. For example, the set of display data may be located by randomly selecting from the set of display data. For another example, the set of display data may be looked up by selecting a particular desired boom amplitude value from the plurality of sets of display data, e.g., the display data corresponding to the largest desired boom amplitude value may be selected as the set of display data to be displayed, or the display data corresponding to the desired boom amplitude at the intermediate position in the plurality of sets of display data may be selected as the set of display data to be displayed.
Taking table 1 as an example, if the current actual working condition data of the crane obtained by the obtaining unit 101 is the working condition data 1 in the performance parameter table, the information processing unit 102 searches the display data corresponding to the current actual working condition data from the performance parameter table 1 in the first mode, and at this time, searches 3 sets of display data. For example, the first set of display data is: the expected boom amplitude 11 and the maximum hoisting height 11'; the second set of display data is: desired boom amplitude 12 and maximum hoist height 12'; the third set of display data is: desired boom amplitude 13 and maximum hoist height 13'. The information processing unit 102 can select one set of display data among them to transmit to the display unit 103 so as to display the set of display data. For example, the information processing unit 102 may select, from the above-described 3 sets of display data, display data corresponding to the largest desired boom amplitude value 13 (it is assumed here that desired boom amplitude 11< desired boom amplitude 12< desired boom amplitude 13) as a set of display data to be displayed. For another example, the information processing unit 102 may select display data corresponding to the desired boom amplitude 12 (here, it is assumed that the desired boom amplitude 11< the desired boom amplitude 12< the desired boom amplitude 13) having an amplitude value at the neutral position as a set of display data to be displayed.
The display unit 103 is configured to display, in the first mode, a maximum hoisting height in a set of display data corresponding to the current actual operating condition data through the first display identifier, and display an expected boom amplitude in a set of display data corresponding to the current actual operating condition data through the second display identifier.
In some embodiments, the first display is identified as a first cursor and the second display is identified as a second cursor, as will be described in detail below in conjunction with FIG. 2. For example, in the case where the information processing unit 102 selects display data corresponding to the desired boom amplitude value 13 (as shown in table 1) as a set of display data to be displayed, the first cursor may display the maximum hoist height 13', and the second cursor may display the desired boom amplitude value 13.
In other embodiments, the maximum hoist height and the desired boom amplitude may also be displayed in the form of a digital gauge. For example, the first display identifier may be a first digital meter and the second display identifier may be a second digital meter.
To this end, a display device for a crane according to some embodiments of the present disclosure is provided. The display device includes an acquisition unit, an information processing unit, and a display unit. The obtaining unit obtains a performance parameter table for the crane and current actual working condition data of the crane. The data in the performance parameter table includes: multiple sets of operating condition data, and multiple sets of display data corresponding to each set of operating condition data. Each set of display data includes a desired boom amplitude and a maximum hoist height corresponding to the desired boom amplitude. The information processing unit is used for searching a group of display data corresponding to the current actual working condition data from the performance parameter table in the first mode. In this first mode, the handle of the crane is not actuated. The display unit is used for displaying the maximum hoisting height in the group of display data corresponding to the current actual working condition data through the first display identifier and displaying the expected amplitude of the suspension arm in the group of display data corresponding to the current actual working condition data through the second display identifier in the first mode. The display device can improve the operation convenience in the crane operation process, and the operation real-time performance is better.
Because the working condition combination conditions are more, the mode difficulty of manually searching the performance table in the prior art is higher, and the requirement on operators is higher. The display device disclosed by the embodiment of the disclosure can conveniently display the expected amplitude of the suspension arm and the maximum hoisting height corresponding to the expected amplitude of the suspension arm, and has lower operation difficulty and lower requirements on operators. In addition, the crane operator can know the hoisting capacity of the current state of the crane according to the display device, so that the crane is favorable for operation convenience and operation safety.
In some embodiments, as shown in fig. 1, the display unit 103 may also be configured to display the minimum hoisting height of the crane through the first display identifier and the minimum boom amplitude of the crane through the second display identifier. For example, the minimum hoisting height of the crane can be a set value of 3m, the minimum boom amplitude of the crane can be a set value of 3m, the minimum hoisting height can be displayed with a first cursor (e.g. 3m), and the minimum boom amplitude can be displayed with a second cursor (e.g. 3 m). Of course, the scope of the disclosed embodiments is not limited to the exemplary values of minimum hoist height and minimum boom amplitude herein. Therefore, the display device can determine the range of the hoisting height and the range of the amplitude of the suspension arm according to the current actual working condition data because the display device also displays the maximum hoisting height and the expected amplitude of the suspension arm. By displaying the lifting height range and the lifting arm amplitude range under the current actual working condition, an operator can know the lifting capacity of the crane under the current actual working condition in real time and perform safety operation.
It should be noted that the minimum hoisting heights under different working conditions may be equal or unequal. For example, different operating conditions may correspond to different minimum hoisting heights. The minimum amplitude of the suspension arms under different working conditions can be equal or unequal. For example, different operating conditions may correspond to different minimum boom amplitudes. The minimum hoisting height and the minimum boom amplitude of the crane can be obtained according to practical situations, as will be understood by those skilled in the art.
In some embodiments, the obtaining unit 101 may be further configured to receive, in the first mode, a first instruction to change the maximum hoist height displayed by the first display identifier. The first instructions include: and the changed maximum hoisting height corresponding to the current actual working condition data. The information processing unit 102 may be further configured to search, in the first mode, an expected boom amplitude corresponding to the changed maximum hoisting height from the performance parameter table according to the changed maximum hoisting height and the current actual working condition data. The display unit 103 can also be used to display the desired boom amplitude corresponding to the changed maximum hoisting height using the second display identifier.
For example, by way of example with reference to the performance parameter table 1, when the handle of the crane is not in motion, it can also be understood that the current actual operating condition data is operating condition data 1 under the condition that the boom of the crane is not moved: the arm length 1 (for example, the arm length 25m), the steel wire rope multiplying power 1 (for example, the steel wire rope multiplying power 1 is 2 times), the boom combination data 1 (for example, the boom combination data 1 includes 80% of the first boom extension, 50% of the second boom extension and 30% of the third boom extension), and the leg extension state 1 (for example, the leg extension state 1 includes the leg fully-extended state). Corresponding to the current actual working condition data, the first cursor of the display unit currently displays the maximum hoisting height as the maximum hoisting height 13' (for example, 20m), and the second cursor currently displays the desired boom amplitude as the desired boom amplitude 13 (for example, 15 m). After receiving the first instruction of changing the current maximum hoisting height, the obtaining unit 101 obtains the changed maximum hoisting height 12' (for example, 16m) corresponding to the current actual working condition data, and transmits the changed maximum hoisting height to the information processing unit 102. The information processing unit 102 finds the desired boom amplitude 12 (e.g. 19m) corresponding to the maximum hoisting height 12 'according to the received changed maximum hoisting height 12' and the current actual operating condition data. The display unit 103 displays the changed maximum hoisting height 12' (e.g., 16m) by the first cursor and the desired boom amplitude 12 (e.g., 19m) corresponding to the changed maximum hoisting height by the second cursor.
Through the technical scheme of the embodiment, the following functions can be realized: when the first cursor is moved, the maximum hoisting height information changes along with the movement of the first cursor, and at the moment, the information displayed by the first cursor is the expected maximum hoisting height under the current working condition combination; the second vernier also moves along with the movement of the first vernier, and the display value of the second vernier is the expected amplitude value of the suspension arm at the changed maximum hoisting height.
In the embodiment, the expected amplitude of the suspension arm corresponding to different maximum hoisting heights is quickly displayed by changing the maximum hoisting height, so that an operator can conveniently plan the amplitude of the suspension arm of the crane in the current actual working condition, thereby realizing safe operation and meeting the requirements of the user on operation convenience and real-time performance.
In other embodiments, the obtaining unit 101 may be further configured to receive a second instruction to change the desired boom amplitude displayed by the second display identifier in the first mode. The second instructions include: and the expected amplitude of the changed suspension arm corresponding to the current actual working condition data. The information processing unit 102 may further be configured to, in the first mode, find the maximum hoisting height corresponding to the changed desired boom amplitude from the performance parameter table according to the changed desired boom amplitude and the current actual working condition data. The display unit 103 can also be used for displaying the maximum hoisting height corresponding to the changed desired boom amplitude by using the first display identifier.
For example, as illustrated in the performance parameter table 1, in the first mode, the current actual operating condition data is operating condition data 1: the arm length 1 (for example, the arm length 25m), the steel wire rope multiplying power 1 (for example, the steel wire rope multiplying power 1 is 2 times), the boom combination data 1 (for example, the boom combination data 1 includes 80% of the first boom extension, 50% of the second boom extension and 30% of the third boom extension), and the leg extension state 1 (for example, the leg extension state 1 includes the leg fully-extended state). Corresponding to the current actual working condition data, the first cursor of the display unit currently displays the maximum hoisting height as the maximum hoisting height 13' (for example, 20m), and the second cursor currently displays the desired boom amplitude as the desired boom amplitude 13 (for example, 15 m). After receiving the second instruction to change the current desired boom amplitude, the obtaining unit 101 obtains the changed desired boom amplitude 12 (for example, 19m) corresponding to the current actual working condition data, and transmits the changed desired boom amplitude 12 to the information processing unit 102. The information processing unit 102 finds the maximum hoisting height 12' (e.g., 16m) corresponding to the changed desired boom amplitude 12 according to the received changed desired boom amplitude 12 and the current actual operating condition data. The display unit 103 displays the changed desired boom amplitude 12 (e.g., 19m) by the second cursor, and displays the maximum hoisting height 12' (e.g., 16m) corresponding to the changed desired boom amplitude 12 by the first cursor.
Through the technical scheme of the embodiment, the following functions can be realized: when the second vernier is moved, the expected amplitude of the suspension arm changes along with the movement of the second vernier, and at the moment, the information displayed by the second vernier is the expected amplitude value of the suspension arm under the current working condition combination; the first vernier moves along with the movement of the second vernier, and the display value of the first vernier is the maximum hoisting height under the changed expected amplitude of the suspension arm.
In the embodiment, the maximum hoisting height corresponding to different expected hoisting arm amplitudes is quickly displayed by changing the expected hoisting arm amplitude, so that an operator can conveniently plan the hoisting height of the crane under the current actual working condition, thereby realizing safe operation and meeting the requirements of the user on operation convenience and real-time performance.
In the above embodiment, the display device can not only determine the range of the hoisting height and the range of the amplitude of the boom according to the current actual working condition data, but also dynamically display the display data under different working conditions by changing the maximum hoisting height or the expected amplitude of the boom.
In some embodiments, each set of display data in the performance parameter table may further include a nominal boom weight corresponding to a desired boom amplitude. The display unit may also be configured to display a nominal boom weight corresponding to the desired boom amplitude via the second display indicia. The rated hoisting weight refers to the maximum hoisting capacity allowed to be hoisted under normal working conditions of the crane.
TABLE 2 exemplary Crane Performance parameters Table
Table 2 is an exemplary crane performance parameter table. As can be seen from table 2, each set of display data may include a nominal hoist weight (e.g., nominal hoist weight 11 ", etc.) corresponding to a desired boom amplitude in addition to the desired boom amplitude and a maximum hoist height corresponding to the desired boom amplitude.
In some embodiments, the second display indicator may also dynamically display a corresponding changed nominal hoist weight by changing the desired boom amplitude or maximum hoist height. This is exemplified below in connection with the performance parameters table 2.
For example, in the first mode, the obtaining unit obtains the current actual operating condition data as operating condition data 1, and at this time, the first cursor displays the maximum hoisting height 13', and the second cursor displays the desired boom amplitude 13 and the rated hoisting weight 13 ″. When the first cursor is moved to change the maximum hoisting height 13 'to the maximum hoisting height 12', the second cursor is correspondingly moved therewith, thereby changing the displayed desired boom amplitude 13 to the desired boom amplitude 12 and the displayed nominal hoisting weight 13 "to the nominal hoisting weight 12". Alternatively, when the second cursor is moved to change the desired boom amplitude 13 to the desired boom amplitude 12, the nominal hoist weight 13 "is also correspondingly changed to the nominal hoist weight 12", and the first cursor is correspondingly moved therewith to change the displayed maximum hoist height 13 'to the maximum hoist height 12'.
In the embodiment, the rated hoisting weight corresponding to the changed expected hoisting arm amplitude is dynamically displayed by changing the expected hoisting arm amplitude or the maximum hoisting height, so that an operator can conveniently and quickly inquire and reasonably plan the hoisting weight of the crane under the current actual working condition, thereby realizing safe operation and meeting the requirements of the user on operation convenience and real-time performance.
In some embodiments, the second cursor displays the sling weight information and the amplitude information simultaneously on a display unit (e.g., a display interface). When the handle is not operated, the crane is in a static state, and the vernier is in a draggable state. When the second vernier is moved by taking the hoisting weight information as a target, the hoisting weight information and the amplitude information simultaneously change along with the movement of the second vernier, and the expected rated hoisting weight under the current working condition combination is displayed at the moment. Meanwhile, the amplitude information display value of the second vernier is the expected amplitude of the suspension arm under the current expected rated suspension weight, and the expected amplitude of the suspension arm is the maximum amplitude value which can be reached at the moment. And moving the second cursor when the amplitude information is taken as a target, wherein the amplitude information changes along with the movement of the second cursor, and the amplitude information displays an expected amplitude value under the current working condition combination. Meanwhile, the hoisting weight information displayed by the second cursor is the maximum hoisting weight (namely the rated hoisting weight) at the current amplitude.
In some embodiments, the obtaining unit 101 may be further configured to obtain, in the second mode, a current actual hoisting height and a current actual boom amplitude of the crane, and transmit the current actual hoisting height and the current actual boom amplitude to the display unit 103.
