In the present application, in order to ensure that the above-described inspection apparatus 10 can accurately evaluate the fit condition between the bucket capacity currently employed by the excavator and the current work object of the excavator, the present application realizes the above-described function by providing a bucket fit inspection method for the above-described inspection apparatus 10. The bucket fit detection method provided by the application is described in detail below.
Referring to fig. 2, fig. 2 is a flow chart of a bucket fit detection method according to an embodiment of the application. In the embodiment of the present application, the bucket fit detection method shown in fig. 2 is as follows.
Step S210, obtaining the bucket capacity to be measured of a target bucket currently used by the target excavator.
In one implementation of the present embodiment, when the detection apparatus 10 needs to determine the to-be-detected bucket capacity of the target bucket currently used by the target excavator, the detection apparatus 10 may directly obtain the specific value of the to-be-detected bucket capacity from the electronic apparatus by sending a bucket capacity obtaining request to the electronic apparatus in which the to-be-detected bucket capacity of the target bucket is recorded. The electronic device to be measured of the target bucket is, but not limited to, a target excavator for automatically measuring the bucket capacity value of the target bucket, and a server or computer device for storing bucket capacities of different models.
In another implementation manner of this embodiment, when the detection apparatus 10 needs to determine the to-be-measured bucket capacity of the target bucket currently used by the target excavator, the detection apparatus 10 may obtain the to-be-measured bucket capacity by controlling the target excavator to measure the bucket capacity value of the target bucket currently adopted by the target excavator. At this time, the specific implementation procedure of step S210 is shown in fig. 3.
Referring to fig. 3, fig. 3 is a flow chart illustrating the sub-steps included in step S210 in fig. 2. In the present embodiment, the step S210 includes sub-steps S211 to S213.
Substep S211, collecting a first weight of the target excavator with the target bucket mounted therein when the target excavator is in an empty state.
In this embodiment, the first weight is a total weight of the target excavator when the target bucket is installed but the excavating work is not formally performed, and the empty state is used for indicating that the target excavator is not currently performing the excavating work. The detection device 10 may determine that the target excavator is currently in an idle state by collecting a hydraulic system working pressure value of the target excavator, and when the collected hydraulic system working pressure value is the minimum pressure in the process of executing the excavating operation by the target excavator, at this time, the detection device 10 will control the target excavator to start an automatic weighing function for the target excavator, so as to obtain a corresponding first weight.
Sub-step S212, calculating the target weight of the target bucket according to the second weight of the target excavator when the target bucket is not installed and the collected first weight.
In this embodiment, the second weight is a weight value of the excavator main body remaining after the target excavator removes the bucket. The detection apparatus 10 may obtain the second weight of the target excavator by performing data reading at the target excavator, and then perform subtraction operation on the obtained first weight and second weight to obtain the target weight of the target bucket, which is indicative of the target bucket weight.
Substep S213, calculating a bucket capacity to be measured corresponding to the target weight of the target bucket according to the preset correspondence between the bucket weight and the bucket capacity.
In this embodiment, the correspondence between the bucket weight and the bucket capacity is used to represent the correspondence between the bucket capacities and the weights corresponding to the different types of buckets. The detection apparatus 10 may calculate a bucket capacity value satisfying a correspondence between the bucket weight and the bucket capacity after measuring the target weight of the target bucket, and use the calculated bucket capacity value as the bucket capacity to be measured of the target bucket.
Referring to fig. 2 again, in step S220, a target object density of a working condition work object currently targeted by the target excavator is obtained.
In one implementation of the present embodiment, when the detection apparatus 10 needs to determine the target object density of the working condition work object that the target excavator currently needs to perform the excavation work, the detection apparatus 10 may directly obtain the specific value of the target object density from the electronic apparatus by sending a density obtaining request to the electronic apparatus in which the target object density of the working condition work object is recorded. The electronic device recorded with the target object density of the working object under the working condition may be, but is not limited to, a target excavator which measures the density value of the working object under the working condition by itself, and a server or a computer device which stores the respective density values of different working objects.
In another implementation of this embodiment, when the detection apparatus 10 needs to determine the target object density of the working condition work object for which the target excavator is currently required to perform the excavation work, the detection apparatus 10 may obtain the target object density by controlling the target excavator to measure the density value of the working condition work object for which it is currently directed. At this time, the specific implementation procedure of step S220 is shown in fig. 4.
Referring to fig. 4, fig. 4 is a flowchart illustrating the sub-steps included in step S220 in fig. 2. In this embodiment, the step S220 includes sub-steps S221 to S223.
In a substep S221, the target weight of the working condition work target excavated by the target excavator each time the target bucket performs the excavating work a plurality of times is collected.
In this embodiment, the detection apparatus 10 may control the target excavator to perform multiple excavation operations on the working condition operation object based on the target bucket, and when the target excavator excavates a certain number of working condition operation objects each time, calculate the weight value of the working condition operation object in the target bucket by collecting parameters such as position information, posture information, and boom cylinder size cavity pressure value of the target excavator, and combining the first weight determined in the sub-step S211, so as to obtain the object weight of the working condition operation object excavated each time by the target excavator in multiple excavation operations.
In the substep S222, for each collected weight of the object, the density of the object to be processed corresponding to the weight of the object is calculated according to the preset bucket filling rate, the bucket capacity to be measured, and the collected weight of the object.
In this embodiment, when determining the weight of the working object excavated by the excavation operation at each time, the detection apparatus 10 multiplies the weight of the object corresponding to the excavation operation by the preset bucket filling rate, and then divides the obtained product value by the value of the bucket capacity to be detected, so as to obtain the density value of the weight of the object, which is estimated correspondingly under the action of the target bucket, that is, the density of the object to be processed corresponding to the weight of the object excavated by the excavation operation. The preset bucket filling rate is used for indicating the probability that the whole bucket capacity of the excavated object is filled when the corresponding bucket performs excavation operation, and the value of the bucket filling rate is in the range of 0% -100%, and can be set to be 65% generally.
And step S223, after calculating the densities of all the objects to be processed, carrying out average value operation on the densities of all the objects to be processed, and taking the calculated density average value as the target object density of the working condition working object.
In this embodiment, the detection apparatus 10 performs a mean value operation on the estimated density of the object to be processed of the working condition working object that is excavated by the target excavator in each excavation operation in multiple excavation operations, and then uses the calculated density mean value as the target object density of the working condition working object, so as to reduce the error of the self-measurement working object density of the target excavator in a mean value operation manner.
Referring to fig. 2 again, in step S230, a target adaptation job bucket corresponding to the target object density is calculated according to the preset correspondence between the object density and the adaptation job bucket.
In this embodiment, the corresponding relationship between the preset object density and the adaptive working capacity is used to represent the optimal working capacity condition that should be selected when the corresponding target excavator works with different densities, and may be expressed in a matrix form. When the detection device 10 determines the target object density of the working condition working object currently aimed at by the target excavator, a target adaptive working capacity corresponding to the target object density is determined based on the corresponding relation.
And step S240, comparing the bucket capacity to be detected with the bucket capacity of the target adapting operation, and outputting the bucket capacity adapting condition of the target bucket and the working condition operation object according to the corresponding comparison result.
In this embodiment, after determining the to-be-detected bucket capacity of the target bucket and the target adaptive working bucket capacity matched with the target object density of the current working condition working object, the detection device 10 may determine whether the current target bucket is suitable for the current working condition working object, whether the excavation efficiency of the excavator on the current working condition working object cannot be exerted, and whether the service life of the working structural member of the excavator is overdrawed by comparing the to-be-detected bucket capacity with the target adaptive working bucket capacity.
Specifically, the step of outputting, according to the corresponding comparison result, the bucket capacity adaptation condition of the target bucket and the working condition working object may include:
if the comparison result is that the bucket capacity to be measured is larger than the target adaptation work bucket capacity, outputting an adaptation result that the bucket capacity of the target bucket is larger relative to the working condition work object;
if the comparison result is that the bucket capacity to be measured is equal to the target adaptation work bucket capacity, outputting an adaptation result of matching the target bucket with respect to the working condition work object bucket capacity;
and if the comparison result is that the bucket capacity to be measured is smaller than the target adaptation work bucket capacity, outputting an adaptation result that the bucket capacity of the target bucket is smaller relative to the bucket capacity of the working condition work object.
When the bucket capacity to be measured is larger than the target adaptive operation bucket capacity, the target bucket can exert the excavating efficiency of the excavator on the current working condition operation object, meanwhile, the operation load of the excavator is increased, the service life of the excavator is reduced, and at the moment, the bucket capacity of the target bucket is larger relative to the working condition operation object, and the bucket with smaller bucket capacity needs to be replaced as much as possible for excavating operation; when the bucket capacity to be measured is equal to the target adaptive working bucket capacity, the target bucket can be indicated to ensure the service life of the excavator while the excavating efficiency of the excavator on the current working condition working object can be exerted, and the target bucket is just adaptive to the working condition working object; when the bucket capacity to be measured is smaller than the bucket capacity of the target adaptive operation, the condition that the target bucket can ensure the service life of the excavator but cannot exert the excavating efficiency of the excavator on the current working condition operation object is indicated, and at the moment, the bucket capacity of the target bucket is smaller relative to the working condition operation object, and the bucket with larger bucket capacity needs to be replaced as much as possible to carry out excavating operation.
In the present embodiment, the three fitting results may be displayed by the display unit 14 in the detection apparatus 10, so that the responsible person of the target excavator may select whether to replace the currently used bucket according to the specific fitting result. In addition, after calculating the to-be-measured bucket capacity of the target bucket and the target adaptive operation bucket capacity estimated based on the target bucket, the detection device 10 displays the to-be-measured bucket capacity and the target adaptive operation bucket capacity on the display unit 14, so that a responsible person can perform numerical reference in the process of selecting the bucket capacity, and the selected bucket capacity is more matched with the current working condition.
In the embodiment of the present application, the detection device 10 may accurately evaluate the adaptation condition between the bucket capacity currently adopted by the excavator and the current working object by executing the above steps S210 to S240, so that the user can conveniently select and take out the bucket corresponding to the bucket capacity, which can not only fully exert the excavating efficiency of the excavator on the current working object, but also ensure the use safety of the working structural member of the excavator for excavating.
In the present application, in order to ensure that the above-described inspection apparatus 10 can also have an accurate evaluation of the fit condition between the bucket capacity and the excavator, so that a responsible person can determine that the bucket capable of fully exerting the engine performance of the excavator is involved in the excavating work, the present application realizes the above-described function by providing another bucket fit inspection method for the above-described inspection apparatus 10. The bucket fit detection method provided by the application is described in detail below.
Referring to fig. 5, fig. 5 is a second flowchart of a bucket fit detection method according to an embodiment of the application. In the embodiment of the present application, the bucket fit detection method shown in fig. 5 is as follows.
Step S250, collecting main pump working pressure, main pump displacement, and engine rotational speed when the target excavator performs an excavating operation based on the target bucket.
In this embodiment, the detection apparatus 10 may control the target excavator to automatically monitor the main pump working pressure, the main pump displacement, and the engine speed when the target bucket is used to perform the excavating operation.
Step S260, corresponding main pump power is calculated according to the collected main pump working pressure, main pump displacement and engine speed.
In this embodiment, the detection apparatus 10 may output the corresponding main pump power by multiplying the collected main pump working pressure, main pump displacement, and engine speed, and then dividing the multiplied value by the operation parameter.
Step S270, determining the power of the external characteristic curve of the engine corresponding to the collected engine speed according to the preset external characteristic curve of the target excavator.
In the present embodiment, the detection apparatus 10 may determine a power value having a value matching the acquired engine speed in a preset engine external characteristic map corresponding to the target excavator to use the power value as the engine external characteristic power corresponding to the engine speed.
And step S280, outputting the bucket capacity adaptation state of the target bucket and the target excavator according to the values of the main pump power and the engine external characteristic curve power.
In this embodiment, when determining the main pump power and the external characteristic power of the engine matched with the target excavator, the detection apparatus 10 determines whether the current target bucket can exhibit the engine performance of the target excavator according to the respective values of the two powers. At this time, the step of outputting the bucket capacity adaptation status of the target bucket and the target excavator according to the magnitude of the main pump power and the external characteristic power of the engine may include:
multiplying the power of the external characteristic curve of the engine by a first preset power utilization rate to obtain a corresponding first power value, and multiplying the power of the main pump by a second preset power utilization rate to obtain a corresponding second power value;
Comparing the first power value with the second power value;
if the first power value is larger than the second power value, outputting an adaptation result of the small capacity of the target bucket relative to the target excavator bucket;
and if the first power value is equal to the second power value, outputting an adapting result of matching the target bucket with respect to the bucket capacity of the target excavator.
The first preset power utilization rate is used for representing the actual expression condition of the target excavator on the theoretically calculated engine external characteristic curve power, and the second preset power utilization rate is used for representing the actual expression condition of the target excavator on the theoretically calculated main pump power, so that evaluation errors caused by directly adopting the main pump power to carry out numerical comparison with the engine external characteristic curve power are avoided. When the first power value is larger than the second power value, the target bucket can be indicated to not fully exert the engine performance of the target excavator under the condition of being mounted on the target excavator, and the bucket capacity of the target bucket is smaller relative to the target excavator; when the first power value is equal to the second power value, it may be indicated that the target bucket is exactly able to fully exploit the engine performance of the target excavator when mounted on the target excavator, when the target bucket is exactly adapted with respect to the target excavator.
In the present embodiment, the two adaptation results may be displayed by the display unit 14 in the detection apparatus 10, so that the responsible person of the target excavator may select whether to replace the currently used bucket according to the specific adaptation result.
In one implementation of the embodiment of the present application, after the detecting device 10 performs the steps S250 to S280, the detecting device 10 may further perform the steps S210 to S240, so as to ensure that the detecting device 10 can accurately evaluate the fit condition between the target bucket and the target excavator and the working object. Optionally, when the detection apparatus 10 performs the step S280 to obtain the result of the small bucket capacity of the target bucket relative to the target excavator, the detection apparatus 10 does not need to perform the steps S210 to S240, so as to directly inform the user that the bucket should be reselected; when the detection apparatus 10 obtains the fitting result of the target bucket that is exactly fitted with respect to the target excavator after performing the step S280, the detection apparatus 10 will perform the subsequent steps S210 to S240 on the basis thereof, so as to ensure that the target buckets participating in the steps S210 to S240 are all capable of fully exerting the engine performance of the target excavator.
In the embodiment of the present application, the detection device 10 may accurately evaluate the adaptation status between the bucket capacity currently adopted by the excavator and the engine performance of the excavator by executing the above steps S250 to S280, so as to facilitate the user to select the bucket capable of fully playing the engine performance of the excavator to participate in the excavating operation.
