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.
Fig. 1 is a schematic flow chart of a gear fault detection method provided by the present invention, as shown in fig. 1, the method includes:
and step 110, acquiring the accelerator gear and the gear voltage of the engineering machinery at the current moment.
Specifically, the construction machine is a machine of various types that performs construction work, such as a crane, an excavator, a bulldozer, and the like. For example, when the engineering machinery is an excavator, an accelerator knob is adopted to control an accelerator, and the flow in a hydraulic system is adjusted mainly by rotating the accelerator knob, so that an engine is stabilized at a corresponding rotating speed, and the action speed of the excavator is controlled. That is, the throttle knob can adjust the gear of the excavator.
The throttle knob is mostly in the form of a slide rheostat. The throttle gear is the throttle grade that throttle knob can be adjusted. The gear voltage is a voltage value corresponding to the accelerator knob rotating to the accelerator gear. Generally, the throttle gear and the gear voltage correspond one to one. For example, in the case of an excavator, the throttle level may be classified into 10 levels according to the magnitude of the engine output. Correspondingly, the throttle knob can correspond to 10 throttle gears and 10 gear voltages respectively. The gear voltage at the moment can be determined according to the corresponding relation between the accelerator gear and the gear voltage and the gear of the accelerator knob, and the gear corresponding to the accelerator knob at the moment can also be determined according to the voltage output at each moment.
However, the working environment of the engineering machinery is severe, the operation process is complex, and hardware damage or reference voltage fluctuation of an accelerator knob is easily caused, so that the accelerator gear and the gear voltage no longer have a strict corresponding relation, namely gear skipping occurs, the gear control effect of the engineering machinery is poor, and misoperation of a driver is easily caused.
And 120, if the difference between the throttle gears at the current moment and the last moment is equal to a preset gear difference, and the difference between the gear voltages at the current moment and the last moment is less than or equal to the preset voltage difference, determining that the throttle knob of the engineering machinery jumps.
Specifically, the preset gear difference is an accelerator gear difference used for measuring whether a gear skipping fault is likely to occur, and an absolute value can be taken. For example, the skip-shift fault of the accelerator knob is mostly between two adjacent gears, and therefore, the preset gear difference may be 1.
The preset voltage difference is a difference value of corresponding voltage changes when the accelerator gear changes, and an absolute value can be obtained. The preset voltage difference can be determined according to a normal range of fluctuation generated by the gear voltage when the accelerator knob is stabilized at any gear during the work of the engineering machinery. For example, when the excavator works and the accelerator knob is stabilized at any gear, the fluctuation range of the gear voltage is [ -0.2V,0.2V ], and the preset voltage difference can be 0.2V.
The accelerator gear and the gear voltage at the current moment are respectively compared with the accelerator gear and the gear voltage at the previous moment, if the difference between the accelerator gear at the current moment and the accelerator gear at the previous moment is equal to a preset gear difference, the fact that the accelerator knob is changed in gear is indicated, and as the changed difference between the accelerator gear and the accelerator gear at the previous moment is equal to a preset unit difference, the accelerator knob has the possibility of gear jump faults, but the accelerator knob is also possible to be manually shifted by a driver. At this time, further determination needs to be performed according to a comparison result of the gear voltage difference between the current time and the previous time, and if the gear voltage difference is less than or equal to a preset voltage difference, the gear voltage can be considered to fluctuate within a normal range, and not to be subjected to drastic change, and the gear voltage can be considered to be not subjected to change approximately. And the comparison result of the throttle gear and the gear voltage at the current moment and the previous moment is integrated, so that the condition that the throttle knob of the engineering machinery jumps can be judged.
The time interval for detecting the gear fault, i.e. the time interval between the current time and the previous time, can be set according to actual needs. Specifically, the time interval of gear fault detection can be set according to the identity of the driver or the type of the construction task due to the difference of the operation habits of each driver or the difference of the construction tasks executed by the construction machine.
For example, different drivers have different operation preferences, and when the same type of construction task is performed, the operation frequency and the gear change stages of the accelerator knob are different, and if the driver cannot be reminded of the occurrence of the gear jump fault of the accelerator knob in time, the rotation speed of the engine may be unstable, and the construction effect may be affected. At this time, the operation time of the accelerator knob by the driver can be collected, and the average value of the time intervals among the operation times is used as the time interval for detecting the gear fault.
For example, a transmission mechanism of a common excavator transmits power of an engine to an actuator such as a hydraulic motor or a hydraulic cylinder via a hydraulic pump to push a work implement to perform various operations. When the excavator walks, rotates, moves a movable arm, moves an arm or moves a bucket, the engine drives the hydraulic pump to move through the coupling. The corresponding operation steps of each kind of construction task are different, for example, the operation frequency of an accelerator knob is different when the excavator shovels soil and walks. The operation time of the accelerator knob can be collected under a specific construction task, and the average value of the time intervals among the operation times is used as the time interval for detecting the gear fault under the construction task.
According to the gear fault detection method provided by the embodiment of the invention, the accelerator gear and the gear voltage of the engineering machinery at the current moment are obtained; if the difference between the throttle gears at the current moment and the last moment is equal to the preset gear difference and the difference between the gear voltages at the current moment and the last moment is less than or equal to the preset voltage difference, the throttle knob of the engineering machinery is determined to jump, the jump gear of the throttle knob can be effectively detected without additionally adding hardware detection equipment, the gear control effect of the engineering machinery is improved, and misoperation of a driver is avoided.
Based on the above embodiment, step 110 then comprises:
and if the difference between the accelerator gear positions at the current moment and the last moment is not equal to the preset gear position difference, determining that the accelerator knob of the engineering machinery has no gear jump.
Specifically, if the difference between the accelerator gears at the current time and the previous time is not equal to the preset gear difference, there may be two situations:
in the first case, the throttle shift position difference between the current time and the previous time is zero, which indicates that the throttle shift position is not changed when the current time is compared with the previous time, and at this time, it can be considered that there is no possibility of the throttle knob jumping.
In the second case, the difference between the throttle positions at the current time and the previous time is not zero, and the difference between the throttle positions is greater than the preset position difference. For example, the construction machine is an excavator, and since the gear skipping generally occurs between adjacent throttle gears, the preset gear difference may be 1. The difference between the accelerator gear at the current moment and the accelerator gear at the previous moment is 2 or other positive integers larger than the preset gear difference, and at this time, the gear change of the accelerator knob can be considered as a result of manual gear shifting of a driver, and the accelerator knob does not jump.
Based on any of the above embodiments, step 110 is followed by:
and if the difference between the throttle gears at the current moment and the last moment is equal to the preset gear difference and the difference between the gear voltages at the current moment and the last moment is greater than the preset voltage difference, determining that the throttle knob of the engineering machinery has not jumped.
Specifically, if the difference between the accelerator positions at the current time and the previous time is equal to the preset position difference, it may be determined that there is a possibility of a gear jump of the accelerator knob.
Further, if the difference between the shift voltages at the current time and the previous time is greater than the preset voltage difference, it indicates that the change value of the shift voltage exceeds the normal fluctuation range of the shift voltage, and at this time, it may be considered as a manual shift operation taken by the driver, for example, an operation of increasing or decreasing the first gear, so that the shift voltage is changed instead of a skip shift.
For example, for an excavator, the preset voltage difference is 0.2V, the difference between the accelerator positions at the current moment and the previous moment is equal to the preset position difference, and the difference between the gear positions at the current moment and the previous moment is 1V.
Based on any of the above embodiments, step 120 includes:
and sending a gear fault alarm signal to a control system of the engineering machinery.
Specifically, it is determined that the accelerator knob of the engineering machine is tripped, at this time, a gear fault alarm signal may be sent to a control system of the engineering machine, and a driver is prompted by a voice alarm or an acousto-optic alarm of the control system.
The control system of the engineering machinery can also control the current accelerator gear to be kept unchanged according to the gear fault alarm signal, so that the unstable rotating speed of the engine caused by gear fluctuation is avoided.
Based on any embodiment, the preset voltage difference is determined based on gear voltage corresponding to adjacent gears of the engineering machine.
Specifically, the preset voltage difference can be determined according to gear voltages corresponding to adjacent gears of the engineering machinery, so that when the accelerator gear difference generated for the accelerator gear of the accelerator knob is equal to the preset gear difference, whether the accelerator knob jumps or not can be accurately judged.
If the preset voltage difference is the difference between the gear voltages corresponding to the adjacent gears, it is difficult to determine whether the generated gear voltage difference is generated by gear skipping or manual operation of the driver. Therefore, the preset voltage difference can be a voltage value smaller than the difference between the gear voltages corresponding to the adjacent gears of the engineering machine, that is, the normal range of fluctuation generated by the gear voltage when the accelerator knob is stabilized at any gear during the work of the engineering machine can be [ -the preset voltage difference, the preset voltage difference ].
For example, in the case of an excavator, the accelerator knob may correspond to 10 accelerator positions, each corresponding to 1V to 10V, and the difference between the gear voltages corresponding to adjacent positions may be 1V. The voltage value of less than 1V is 0.9V as the preset voltage difference, and the gear fault of the excavator can be detected. At this time, the normal range of fluctuation of the shift voltage when the accelerator knob is stabilized in any shift position may be [ -0.9V, 0.9V ].
Based on any of the above embodiments, the preset voltage difference corresponds to the type of the engineering machine one to one.
Specifically, the type of the working machine is the kind and model of the working machine. There are a wide variety of types of construction machines, and each type of construction machine has a variety of models. For example, excavators can be classified into a front shovel, a back shovel, a dragline excavator and a grapple excavator according to the types of buckets, and can be classified into a large excavator, a medium excavator and a small excavator according to the types of the excavators.
Because the types of the engineering machinery are different, the engines are different, and the gear voltage of the accelerator knob is also different. Therefore, different preset voltage differences can be set according to each type of engineering machinery, and accuracy of gear fault detection is improved.
Based on any of the above embodiments, fig. 2 is a second schematic flow chart of the gear fault detection method provided by the present invention, as shown in fig. 2, the method includes:
the method comprises the following steps: firstly, the current accelerator knob voltage of the engineering machinery and the corresponding gear information are recorded as T1 voltage and T1 gear respectively.
Step two: after a set time T, the accelerator knob voltage and the corresponding gear information at the moment are recorded and recorded as the T2 voltage and the T2 gear respectively.
Step three: taking a difference value between the gear information at the time of T2 and the gear information at the time of T1, and then taking an absolute value, wherein when the result is 1, the result shows that the possibility of small-range rotation of the accelerator knob due to the fluctuation of reference voltage or the unfixed and firm accelerator knob exists at the moment, namely, the gear skipping phenomenon can exist, and further judgment is needed; if the gear is not 1 after the difference value is taken, it is determined that there is no gear skip caused by the above reasons, that is, it is determined that the gears are kept consistent or the driver manually selects the gear. At this time, no processing is performed, and only the gear position and voltage information at the time T2 is assigned to the time T1, and the next cycle judgment is waited for.
Step four: and when the step three judges that the risk of skipping the gear exists, executing the step. The absolute value of the difference value of the voltage values at the time T2 and the time T1 is obtained, the result is compared with a set threshold value, when the result is smaller than the set threshold value, a gear skipping is judged to exist at the moment, an alarm operation is carried out or the gear at the previous time is kept unchanged, and the effect of reminding a driver or reducing the fluctuation of the rotating speed of the engine is achieved; if the result is larger than the set threshold value, the driver is judged to manually increase the first gear or reduce the first gear at the moment, and the phenomenon of gear skipping is avoided. At this time, no processing is performed, and only the gear position and voltage information at the time T2 is assigned to the time T1, and the next cycle judgment is waited for.
The gear fault detection method provided by the embodiment of the invention can effectively detect the condition of gear skipping of two adjacent gears caused by reference voltage fluctuation or small amplitude jitter of an accelerator knob, thereby reminding a driver or keeping the condition that the rotating speed of an engine cannot fluctuate in the gears to cause unstable rotating speed; the related functions can be realized only by modifying the program without adding additional sensors or other equipment; the time interval T and the voltage change threshold may be opened to developers as parameters to modify to facilitate adaptation to different devices.
