Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The following describes a method, a device, equipment and an excavator for determining the bucket number of the excavator, in accordance with the present invention, with reference to fig. 1 to 4.

Fig. 1 is a schematic flow chart of a method for determining the bucket number of an excavator provided by an embodiment of the present invention, and fig. 2 is a schematic broken-line diagram of instantaneous oil consumption of an excavator provided by an embodiment of the present invention.

As shown in fig. 1, a method for determining the bucket number of an excavator provided in an embodiment of the present invention includes the following steps:

101. the method comprises the steps of collecting instantaneous oil consumption rate data of an excavator engine within preset time.

In a specific implementation process, the instantaneous oil consumption rate data of the excavator engine within a preset time is firstly collected, for example, if the preset time is ten minutes, the instantaneous oil consumption data corresponding to all the moments of the excavator within 10 minutes is collected, and a specific collection mode may be that the instantaneous oil consumption rate data of the excavator engine within the preset time is collected through a Controller Area Network (CAN) bus. Usually, one working cycle of the excavator is about 12 seconds, ten minutes corresponds to a plurality of working cycles of the excavator, the instantaneous oil consumption rate at all times is collected, and different oil consumption data at different operation times can be clearly known.

102. And determining the number of buckets of the excavator within the preset time according to the data of the instantaneous oil consumption rate based on the incidence relation between the instantaneous oil consumption rate and the action of the excavator.

The determining of the number of the excavator buckets within the preset time according to the instantaneous oil consumption rate data may be that an instantaneous oil consumption rate curve within the preset time is drawn according to the instantaneous oil consumption rate data, and specifically, after the instantaneous oil consumption rate data at all times within the preset time are acquired, the instantaneous oil consumption data at all times within the preset time are summarized, and the instantaneous oil consumption rate curve within the preset time is drawn. The instantaneous oil consumption rate curve graph can be a two-dimensional line graph, the abscissa represents time, and the ordinate represents instantaneous oil consumption, so that a relation graph of time and instantaneous oil consumption in preset time can be clearly obtained.

After a corresponding time and instantaneous oil consumption curve graph is obtained, based on the incidence relation between the instantaneous oil consumption rate and the action of the excavator, the number of buckets of the excavator in the preset time can be measured according to the instantaneous oil consumption curve graph. As shown in FIG. 2, instantaneous oil consumption of the excavator in each stage during operation is different, A-B-C-D is oil consumption data of a single cycle period, and the characteristic can be used for judging a working cycle period of the excavator due to the fact that the time span of A-B is large. Because the torque required by each action is different and the main pressure of the main pump is different, the torque required by the engine is different, the torque of the engine corresponds to the fuel injection quantity, the torque is different, the fuel injection quantity is different, the instantaneous fuel consumption rate is different from the differential angle, therefore, the working cycle of the excavator is distinguished according to the change rule of the instantaneous oil consumption rate of the engine, so that the number of the measuring hoppers is measured, the single-cycle oil consumption of the excavator is approximately reduced by the movable arm, the required torque is lower, the instantaneous oil consumption rate of the engine is lower, the torque required by the bucket rod excavation, the bucket excavation, the movable arm lifting loading and unloading rotation is larger, the instantaneous oil consumption rate of the engine is very high, after bucket unloading and shovel unloading, the instantaneous oil consumption rate is very low, the torque required by the circular rotation is large, the instantaneous oil consumption rate is relatively high, and then the movable arm descends to finish a working cycle, and the instantaneous oil consumption rate of the engine is changed regularly. The completion of one working cycle can be determined according to the change of the oil consumption in one working cycle, and then the specific bucket number of the excavator is determined according to the change period of the oil consumption. For example, if the period of the change in fuel consumption is 78 periods, the number of buckets of the excavator corresponds to 78 buckets. Of course, other calculation methods such as obtaining the highest point of the oil consumption data, acquiring the highest point data once to indicate one bucket, and the like, are also possible, and the calculation of the bucket number of the excavator, which is completed according to the instantaneous oil consumption data, is within the protection scope of the present invention.

The association relationship between the instantaneous oil consumption rate and the action of the excavator is established in advance, and is usually established before the instantaneous oil consumption rate data of an engine of the excavator within preset time is collected, wherein the specific establishment process comprises the following steps: the method comprises the steps of firstly obtaining circular motion flow information when the excavator works, wherein the circular motion flow information comprises movable arm descending data, arm excavating data, bucket excavating data, movable arm lifting data, unloading rotation data, arm unloading data, bucket unloading data and circular rotation data, and the circular motion flow information represents the whole single-cycle flow, namely the state from the beginning of descending of a driven arm to the state before returning to the descending of the movable arm again after the excavation is completed is a cycle period. Respectively collecting the instantaneous oil consumption rate of each datum in the cyclic action flow information; and establishing an incidence relation between the instantaneous oil consumption rate and the excavator action according to the instantaneous oil consumption rate of the data corresponding to each action, namely obtaining a regular relation between the oil consumption change and the cycle period, and taking the regular relation as the incidence relation between the instantaneous oil consumption rate and the excavator action, so that the corresponding excavator bucket number can be quickly calculated through the change of the instantaneous oil consumption.

According to the method for determining the bucket number of the excavator, provided by the embodiment of the invention, instantaneous oil consumption rate data of an engine of the excavator within preset time is collected; the number of the excavator buckets within the preset time is determined according to the instantaneous oil consumption rate data based on the incidence relation between the instantaneous oil consumption rate and the excavator actions, the corresponding number of the excavator buckets can be automatically calculated by acquiring the instantaneous oil consumption rate when the excavator works and then according to the incidence relation between the instantaneous oil consumption rate and the excavator actions, and as the instantaneous oil consumption rate changes of the excavator in one working cycle are the same, regular transformation can be realized after a plurality of cycles, the automatic metering of the number of the excavator buckets can be rapidly completed through regular analysis, the problem of inaccurate manual metering is solved, and the accuracy of the metering of the number of the excavator buckets is effectively improved.

Further, in this embodiment, after determining the number of buckets of the excavator within the preset time, the method further includes: counting the total oil consumption of the excavator within a preset time; the working efficiency of the excavator is determined according to the total oil consumption and the bucket number of the excavator, the bucket number and the total oil consumption of the excavator are quickly inquired, the working efficiency of the excavator can be quickly determined, and the problem of complicated operation of manually detecting the oil consumption efficiency is solved.
