[0066] The following is combined with Figure 1-8 This application is described in further detail.

[0067] The present application embodiment discloses a method for determining the working time of an engineering machinery vehicle, referring to Figure 1 , including the following steps:

[0068] S101, obtaining vibration frequency;

[0069] S102, obtaining a vibration frequency amplitude of the device according to the vibration frequency;

[0070] S103, analyzing the vibration frequency amplitude according to the preset state rule to determine the operating state;

[0071] S104, obtaining target duration according to the running status;

[0072] S105. Determine the working duration according to the target duration.

[0073] In this embodiment, in order to facilitate the description of this solution, step S101 to step S102 take mechanical equipment as an example, and the vibration frequency of the mechanical equipment can be obtained through a vibration sensor. Any mechanical equipment will generate vibrations in the process of converting input energy into useful work. The strength of the vibration is related to the operating state of the mechanical equipment. Different operating states of the mechanical equipment correspond to different vibration frequencies. In order to further determine the operating state of the mechanical equipment, the vibration frequency amplitude of the mechanical equipment over a period of time can be obtained. Since there are large differences between the vibration characteristics of mechanical equipment, different vibration standards should be established for different mechanical equipment.

[0074] In step S103 of this embodiment, the preset state rule refers to the vibration frequency amplitude standard when the mechanical equipment is in different states. The vibration frequency amplitude is the vibration amplitude range of the mechanical equipment under steady-state operating conditions. The actual vibration frequency amplitude of the mechanical equipment is compared according to the preset state rule to match and determine the actual operating state of the current mechanical equipment.

[0075] In addition to useful work, the energy consumed by mechanical movement also produces normal vibrations in the friction loss of mechanical transmission. These vibrations contain various changes in the moving parts of the machine. Mechanical equipment will generate vibrations in the process of converting input energy into useful work. For example, the vibration frequency amplitude standard of an excavator in working state is 30Hz-40Hz, and the vibration frequency amplitude standard of an excavator in standby state is 20Hz-30Hz. At this time, if the vibration frequency amplitude of the excavator is 26Hz-29Hz, it means that the excavator is in standby state.

[0076] In this embodiment, step S104 to step S105 record the target duration of the operation state of the mechanical equipment according to the operation state of the mechanical equipment, and the target duration refers to the time spent by the mechanical equipment under steady-state operation. According to the target durations corresponding to different operation states of the mechanical equipment, the working time of the mechanical equipment is determined from the target durations.

[0077] In the method for determining the working time of equipment, the corresponding vibration frequency amplitude is obtained according to the vibration frequency of the equipment, and the current operating state of the equipment is determined in combination with the preset state rules corresponding to the vibration frequency amplitude of the equipment. Then, the corresponding target duration of the equipment is obtained according to the operating state of the equipment. Finally, the working time of the equipment is determined according to the obtained target duration, thereby solving the problems of high cost and difficult installation of calculating the working time of the equipment, and effectively determining the working time of the equipment.

[0078] In one implementation of this embodiment, Figure 2 As shown, the preset state rule includes a preset working state standard, the operating state includes the working state, and step S103 includes the following steps:

[0079] S201, determining whether the vibration frequency amplitude meets the preset working state standard;

[0080] S202: If the vibration frequency amplitude meets the preset working standard, obtain and analyze the working vibration frequency amplitude value to determine the working state.

[0081] In actual application, the preset working state standard refers to the vibration frequency amplitude standard generated when the mechanical equipment is in a working state, and the working vibration frequency amplitude value refers to the frequency value within the working vibration frequency amplitude. By obtaining whether the actual vibration frequency amplitude of the mechanical equipment meets the corresponding preset working state standard, it can be determined whether the mechanical equipment is currently in a working state.

[0082] For example, the standard vibration frequency amplitude of the excavator in working state is 30Hz-40Hz. The actual vibration frequency amplitude of the excavator is currently obtained and is stable at 31Hz-36Hz, which means that the excavator is currently in working state. Therefore, compared with judging the operating state of the mechanical equipment based only on the vibration frequency corresponding to the unit time, judging the operating state of the mechanical equipment based on the vibration frequency amplitude within the specified time is more accurate.

[0083] In one implementation of this embodiment, Figure 3 As shown, obtaining and analyzing the working vibration frequency amplitude value and determining the working state includes the following steps:

[0084] S301, determining whether the working vibration frequency amplitude value within a preset time period exceeds a preset working vibration frequency amplitude value;

[0085] S302: If the working vibration frequency amplitude value exceeds the preset working vibration frequency amplitude value within the preset time length, obtain the exceeding time length of the working vibration frequency amplitude value exceeding the preset working vibration frequency amplitude value, analyze the exceeding time length, and determine the working state.

[0086] In actual use, the preset duration refers to the analysis time of the steady-state operation of the mechanical equipment, the preset working vibration frequency amplitude value refers to the minimum and maximum values ​​within the working frequency amplitude of the mechanical equipment, and the exceeding duration refers to the time period when the vibration frequency of the mechanical equipment exceeds the preset working vibration frequency amplitude value under the steady-state operation condition. The vibration frequency of the mechanical equipment will be within a certain range under the steady-state operation condition, but in actual situations, the mechanical equipment will be affected by some other external factors under the steady-state operation condition.

[0087] For example, when an excavator is moving, the vibration frequency of the road surface is superimposed on the working vibration frequency. The vibration frequency of the road surface refers to the vibration of the car caused by the uneven road surface and rotating parts such as the engine, transmission system and wheels when the car is driving. Usually, the uneven road surface is the basic input of vibration of mechanical equipment such as excavators. On the other hand, the car will vibrate up and down when driving. The vibration frequency varies according to the tire pattern, speed and shock absorber hardness, and is also related to the driving speed on the road. The faster the speed, the faster the frequency.

[0088] When the excavator is driving on the road, the amplitude value of the excavator's working vibration frequency may exceed the preset working vibration frequency amplitude value. The vibration frequency of the excavator when working in situ is 34Hz, and the vibration frequency of the road surface is 20Hz. The working vibration frequency of the excavator during movement is 54Hz, and the maximum amplitude value standard of the vibration frequency of the excavator when it is in working state is 40Hz. The operation time exceeding 40Hz of the excavator is recorded and the actual working state of the excavator is determined by analysis, so as to improve the accuracy of judging the working state of the equipment.

[0089] In one implementation of this embodiment, Figure 4 As shown, analyzing the duration of the overtime and determining the working status includes the following steps:

[0090] S401, calculating the proportion of the overtime duration within the preset duration;

[0091] S402, determining whether the excess duration ratio meets the abnormal duration ratio;

[0092] S403: If the excess time ratio meets the preset abnormal time ratio, the working state is determined to be an abnormal working state;

[0093] S404: If the excess time ratio does not meet the preset abnormal time ratio, the working state is determined to be a normal working state.

[0094] It should be noted that the proportion of excess time refers to the proportion of the excess time to the preset time, and the proportion of abnormal time refers to the proportion of the time spent by the vibration frequency of the mechanical equipment exceeding the working vibration frequency amplitude value within the preset time period, which is greater than the time spent by the mechanical equipment at its normal working vibration frequency.

[0095] For example, the preset duration is 20 minutes, and the abnormal duration ratio is the time that the vibration frequency of the mechanical equipment exceeds the working vibration frequency amplitude value, which does not exceed 30% of the preset duration. After measurement and recording, the time that the vibration frequency of the excavator exceeds the working vibration frequency amplitude value is 10 minutes. The percentage of the excavator's exceeding duration is 10 minutes / 20 minutes*100%=50%. At this time, it can be determined that the exceeding duration ratio does not meet the abnormal duration ratio, and the excavator is determined to be in an abnormal working state. This facilitates the subsequent determination of the working time of the equipment and reduces the interference of the abnormal state on the determination of the working time of the equipment.

[0096] In one implementation of this embodiment, Figure 5 As shown, step S104 includes the following steps:

[0097] S501, according to the normal working state, obtain the working time and the exceeding time of the working vibration frequency amplitude value within the preset time;

[0098] S502, obtaining a non-operating frequency amplitude value according to the exceeding time length;

[0099] S503, analyzing the non-working frequency amplitude value to obtain the corresponding target exceeding time;

[0100] S504: Obtain the target duration according to the working duration and the target exceeding duration.

[0101] In actual application, the non-working frequency amplitude value refers to the amplitude value after removing the normal working frequency amplitude value of the mechanical equipment, including the maximum and minimum amplitude values ​​of the non-working frequency. Because it has been determined that the mechanical equipment is in a working state at this time, the appearance of the non-working frequency amplitude value within the preset time length also considers that the mechanical equipment is in a working state at this time.

[0102] For example, when the excavator digs up some rocks and other materials, the normal power of the excavator can no longer handle materials heavier than ordinary soil, and the excavator engine power needs to be increased for compensation. When the excavator is in the compensation power, the vibration frequency amplitude value of the excavator exceeds the normal working frequency amplitude value. According to the working frequency amplitude and non-working frequency amplitude when the excavator is in the working state, the working time corresponding to the working frequency amplitude and the target exceeding time corresponding to the non-working frequency amplitude are obtained respectively, and the corresponding target time is obtained according to the working time and the target exceeding time. This improves the accuracy of determining and calculating the working time when the equipment is in the working state.

[0103] In one implementation of this embodiment, Figure 6 As shown, analyzing the non-working frequency amplitude value and obtaining the corresponding target exceeding time includes the following steps:

[0104] S601, determining whether the non-operating frequency amplitude value meets the preset external interference frequency standard;

[0105] S602: If the non-operating frequency amplitude value meets the preset external interference frequency standard, the interference frequency duration is obtained as the target duration.

[0106] In actual application, the preset external interference frequency standard refers to the various interference frequency standards that the mechanical equipment is subject to when it is in working state. The vibration frequency of the mechanical equipment during normal operation will inevitably be affected by some external factors. For example, if the mechanical equipment collides or falls during operation, abnormal vibration frequency will be generated in a relatively short period of time, thereby affecting the vibration frequency of the mechanical equipment during normal operation.

[0107] For example, when excavating, the excavator frequently collides with the nearby rock wall to generate abnormal vibration frequency, and then generates a corresponding non-working frequency amplitude value. After judging that the non-working frequency amplitude value at this time meets the preset external interference frequency standard, the corresponding interference frequency duration is obtained as the target collision duration. Because the excavator frequently collides with nearby rocks to generate abnormal vibration frequency during excavation, it is inevitable. Therefore, recording the duration of the abnormal vibration frequency facilitates the analysis of abnormal conditions of the excavator during operation, thereby improving the objectivity in determining the working time of the computing equipment.

[0108] In one implementation of this embodiment, Figure 7 As shown, after analyzing the vibration frequency amplitude according to the preset state rule and determining the operating state, the following steps are included:

[0109] S701, obtaining operating parameters of the device according to the operating status;

[0110] S702, determining whether the operating parameters meet the preset operating parameter standards;

[0111] S703: If the operating parameters meet the preset operating parameter standards, obtain a corresponding approval signal.

[0112] In actual use, the operating parameters of the equipment refer to the operating parameters of the mechanical equipment in different states, and the preset operating parameter standards refer to the parameter standards corresponding to the mechanical equipment when it is in the target state. For example, the vibration frequency is used to determine that the excavator is in working state, and the power of the excavator engine is 103kW. The engine working parameters corresponding to the preset operating parameter standards are 98kW-120kW. It can be determined that the engine power operating parameters of the excavator at this time meet the corresponding standards, and the corresponding working state approval signal is obtained, thereby improving the accuracy of the equipment state judgment and making the calculation of the equipment working time more accurate.

[0113] The present application embodiment discloses a system for determining the working time of an engineering machinery vehicle, referring to Figure 8 , including an acquisition module 1, an analysis module 2 and a determination module 3.

[0114] The vibration frequency of the device is acquired according to the acquisition module 1, and the vibration frequency amplitude is obtained according to the vibration frequency of the device, which is convenient for the analysis module 2 to analyze and determine the device status. The analysis module 2 determines the current operating status of the device in combination with the preset status rule corresponding to the vibration frequency amplitude of the device, and then obtains the target duration corresponding to the device according to the operating status of the device. Finally, the working time of the device is determined according to the acquired target duration through the determination module 3, thereby solving the problem of high cost and difficult installation of calculating the working time of the device, and then effectively determining the working time of the device.
