Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Fig. 1 is a flowchart of a method for calculating the number of scoops of a loader according to an embodiment of the present invention, where the method may be applicable to a case of counting the number of scoops of the loader during a scooping operation, and may be executed by a telematics processor t_box configured to the loader, and referring to fig. 1, the method includes the following steps:
s110, sequentially detecting the working parameters of each preset class of the loader in each detection period.
When the loader executes the shovel loading operation, the working parameters of the preset categories are changed according to a certain rule. In this embodiment, the t_box sequentially detects these working parameters to determine whether the loader is executing the shovel loading operation.
It should be noted that, in the present embodiment, the detection period is not a fixed duration, and different detection periods may have different durations. For example, in a certain detection period, the loader just executes the shovel loading operation, and then the T_Box runs completely through the detection program of each working parameter in the detection period; in another detection period, the loader does not execute the shovel loading operation, the T_Box detects that a certain working parameter does not meet the requirement and ends the detection period, namely, the T_Box cannot completely run the detection program of all the working parameters, and obviously, the detection periods of the two cases have different detection durations.
S120, timing and updating the working parameters meeting the requirements based on a preset timer, wherein each working parameter corresponds to a timer.
The purpose of timing the working parameters meeting the requirements is to count the total operation time length of the working parameters meeting the requirements, so as to detect whether the loader completely executes the whole process of the shovel loading operation by counting the total operation time length.
In this embodiment, one working parameter corresponds to one timer, and the t_box counts the running duration of each working parameter in a state meeting the requirement through each timer.
S130, if any working parameter does not meet the requirement, ending the current detection period.
And if the working parameters are not in accordance with the requirements, the T_Box does not detect the parameters and other parameters after the parameters, directly exits from the current detection period, and re-executes the detection program in the new detection period after waiting for a preset interval time.
And S140, detecting the timing result of each timer.
And detecting the timing result of each timer, namely detecting whether the accumulated timing duration of each timer reaches the set condition. Because the loader forms a complete shovel loading cycle from the preparation of shovel loading to the execution of shovel loading to the completion of unloading when performing shovel loading, it is apparent that the shovel loading cycle has a certain length of time. This step is to compare the accumulated time duration of each timer with the duration that each operating parameter should be in a shovel cycle.
And S150, if all the timing results meet the preset conditions, carrying out one-time accumulation calculation on the shovel bucket number of the loader.
If the timing results of the timers meet the requirements, the loader completely executes the shovel loading operation once, and at the moment, the T_Box executes one accumulation calculation on the shovel loading bucket number so as to update the shovel loading bucket number. The accumulated calculation in the step is to add 1 on the basis of the last counting value, so that the number of shovel loading hoppers is updated once every time the shovel loading operation is completed, and when the shovel loading operation is finished, the T_Box counts how many times the loader is completed in total.
According to the method for calculating the shovel loading bucket number of the loader, the T_Box acquires working parameters of preset categories of the loader, the determined working parameters are detected successively in each detection period, if the working parameters meet the requirements, the corresponding counters are used for carrying out timing accumulation on the parameters once, if the working parameters are detected to be out of the requirements, the current detection period is exited, when the detection period is exited, whether the timing results of the timers meet the requirements is detected, if the timing results of the timers meet the requirements, the loader is determined to have carried out shovel loading operation of one standard flow, and the T_Box carries out one accumulation calculation on the shovel loading bucket number. Compared with the prior art, the method and the device have the advantages that on the premise of not increasing hardware cost, the information in the operation process of the loader is collected through the T-BOX, and the number of the operation buckets of the loader can be obtained after proper operation is performed, so that the cost is low, and the application range is wide.
Optionally, on the basis of the above technical solution, after performing an accumulation calculation on the number of scoops of the loader, the method further includes:
each timer is cleared to control the re-timing of each timer during a new detection period.
After the shovel loading operation is completely executed, the T-BOX clears each timer, so that the influence of the previous timing result on the shovel loading bucket number counting in the subsequent shovel loading operation process is avoided. After zero clearing, the T-BOX starts a new detection period after waiting for a set interval time, and re-detects the working parameters of each preset type of the loader according to the steps in the new detection period. And (3) repeatedly executing the steps by the T_Box until the loader does not carry out the shovel loading operation, and counting to obtain the number of shovel loading hoppers completed in the whole shovel loading operation process.
Optionally, fig. 2 is a flowchart of another method for calculating the bucket number of a loader according to an embodiment of the present invention, where the method is optimized based on the foregoing embodiment, and referring to fig. 2, the method includes the following steps:
s210, detecting the gear, the throttle, the vehicle speed and the load rate of the loader in sequence in each detection period.
One standard shovel loader operation is shown in fig. 3. The whole process is divided into 4 steps: and (3) carrying out shoveling to a shoveling point, reversing, returning, turning, carrying out unloading to a discharging point, and returning to a starting point.
When the loader reaches a shovel loading operation point and starts shovel loading operation, the gear is a forward gear, the vehicle speed gradually decreases to zero, the accelerator opening is increased to increase the power of the working device, and the load factor of the loader also starts to increase. After the shovel loading is completed, the loader starts to shift and reverse, and the speed of the vehicle rises. In this process, the operating parameters of the loader at the point of shovel loading are typical. Fig. 4 is a graph showing the change of each working parameter when the loader executes the shovel loading operation, and as can be seen from fig. 4, in a complete shovel loading operation flow, the gear, the vehicle speed, the throttle signal and the engine load rate of the loader are sequentially changed. The step is based on the typical characteristics, and whether the loader is executing the shovel loading operation is detected by sequentially detecting the gear, the speed, the throttle signal and the engine load factor parameters of the loader.
In the whole shovel loading operation process, the gear, the speed, the throttle signal and the engine load rate of the loader are all broadcast and sent on the CAN bus, so that the T_Box in the embodiment CAN acquire the gear, the throttle, the speed and the load rate of the loader through the CAN bus. Optionally, the t_box may also directly collect the gear, the vehicle speed, the throttle signal and the engine load factor of the loader. For example, the t_box may obtain a gear signal by collecting a handle signal of the loader. That is, the specific method of the t_box for acquiring the gear, the vehicle speed, the accelerator signal, and the engine load factor of the vehicle is not limited in this embodiment.
S220, when the gear is a forward gear, controlling the first timer to execute accumulation timing of a preset time length, wherein the preset time length is the interval time of adjacent detection periods; when the throttle is greater than or equal to a preset throttle threshold, controlling the second timer to execute one accumulated time of the preset duration; when the vehicle speed is smaller than or equal to a preset vehicle speed threshold value, controlling a third timer to execute one accumulation timing of the preset time length; and when the load rate is greater than or equal to a preset load rate threshold value, controlling the fourth timer to execute one accumulation timing of the preset duration.
According to the analysis, the gear is a forward gear, the gear signal meets the requirements, the throttle, the vehicle speed and the load rate are measured through corresponding thresholds, and when the throttle, the vehicle speed and the load rate are greater than or equal to the corresponding thresholds, the throttle, the vehicle speed and the load rate meet the requirements.
The aim of this step is: the time duration for meeting the requirements of the gear, the accelerator, the vehicle speed and the load rate is counted correspondingly by respectively configuring timers for the gear, the accelerator, the vehicle speed and the load rate. If all the four working parameters meet the requirements, counting by the four timers, namely counting the four working parameters in the process of executing the shovel loading operation of the loader. Obviously, if the total time length of each of the four timers meets the requirement, the loader is indicated to execute a complete shovel loading operation flow.
And S230, if any working parameter does not meet the requirement, ending the current detection period.
When any parameter is not in accordance with the requirement, the loader is not executed with the shovel loading operation, and the T-BOX exits from the current detection period. Accordingly, the parameter and other parameters following the parameter are not clocked during the present detection period.
For example, if the vehicle speed is detected to be greater than the vehicle speed threshold value in the current detection period, the third timer and the fourth timer do not count up. Or when the gear is detected, if the gear is not a forward gear, the first timer, the second timer, the third timer and the fourth timer do not execute timing accumulation in the detection period, but directly exit the current detection period, and start the next detection period after waiting for the set interval time.
Obviously, the timing screening of the working parameters which do not meet the requirements is realized by executing the steps, so that the final timing result of each timer accurately reflects whether the loader is executing the shovel loading operation.
S240, detecting timing results of the timers.
S250, if the timing time of the first timer is greater than or equal to the first timing threshold, and the timing time of the second timer, the timing time of the third timer and the timing time of the fourth timer are all greater than or equal to the second timing threshold, performing one-time accumulation calculation on the bucket number of the loader.
And if the timing time of the first timer is longer than or equal to the first timing threshold, and the timing time of the second timer, the timing time of the third timer and the timing time of the fourth timer are all longer than or equal to the second timing threshold, the timing result accords with the preset condition.
As can be seen from fig. 3 and 4, the loader is in forward gear until the loading operation is completed before the loader is ready for the loading operation, and thus the accumulated count result of the first timer can be used to measure whether the loader has completely traveled the path from the starting point to the loading point.
When the loader is executing the shovel loading operation, the throttle, the vehicle speed and the load rate can be continued for a period of time in a state meeting the requirements, so that whether the timing results of the second timer, the third timer and the fourth timer meet the requirements can be used as a basis for judging whether the shovel loading operation of the loader is performed. It can be seen that if the timing results of the first timer, the second timer, the third timer and the fourth timer all meet the requirements, it indicates that the loader completely executes a shovel loading operation.
And S260, if the timing duration of the first timer is smaller than the first timing threshold, or the timing duration of any one of the second timer, the third timer and the fourth timer is smaller than the second timing threshold, starting the next detection period after waiting for the preset interval time.
If the timing duration of the first timer is smaller than the first timing threshold, the loader does not completely run the distance from the starting point to the loading point, and therefore the loader is not qualified in the loading operation process.
If the timing duration of the second timer or the third timer or the fourth timer does not reach the second timing threshold, the loader does not execute the shovel loading action.
According to the embodiment of the invention, the T_Box counts the gear, the accelerator opening, the vehicle speed and the engine load rate of the loader by setting the corresponding timers, integrally analyzes the timing results of the timers, automatically recognizes whether the loader executes the shovel loading operation, and automatically calculates the shovel loading bucket number when the loader is determined to completely execute the shovel loading operation once. According to the embodiment of the invention, on the basis of the current general T-BOX, the existing signal of the loader is collected, so that the calculation of the shovel loading bucket number of the loader is realized, the hardware cost is not required to be increased, an operator is not required to perform special operation, and the normal operation of the loader is not influenced. According to the embodiment of the invention, the thresholds can be flexibly modified and set according to different working materials of the loader. The wireless communication capability of the T-BOX is very convenient for realizing the on-line setting and remote setting of the parameters.
Optionally, fig. 5 is a flowchart of a method for calculating the number of scoops of a loader according to an embodiment of the present invention, where the method is optimized based on the foregoing embodiment, and referring to fig. 5, and includes the following steps:

Similarly, this step is specifically to control the third timer to accumulate an interval time.

S530, the fourth timer performs one time of timing accumulation.
This step is to control the fourth timer to accumulate an interval time. After the present step is performed, the current detection period is ended, and the T-BOX returns to step S420 to wait for the next detection period to start again to detect the gear.

If the conditions in steps S550 and S560 are both satisfied, that is, the timing duration of the first timer is greater than the first timing threshold, and the timing durations of the second timer, the third timer and the fourth timer are all greater than the second timing threshold, it indicates that the loader has completely performed a shovel loading operation, and the T-BOX performs step S570; otherwise, step S580 is entered.
S570, performing one-time bucket count.
After the judgment of the steps, the loader is shown to have completely executed one shovel loading operation, and the T-BOX automatically counts and accumulates the shovel loading bucket number once through the built-in counter, namely, accumulates once on the basis of the counting of the historical shovel loading bucket number so as to update the shovel loading bucket number.
S580, clearing each timer.
The step is to zero the timers, so that the timers are re-timed according to the detection result in a new detection period.
