[0062] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0063] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0064] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant laws, regulations and standards, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0065] Excavators are extremely necessary and widely used in modern engineering construction. They can quickly and efficiently complete large-scale operations in various harsh environments, ensuring the smooth completion of engineering construction. The bridge box is one of the important mechanical parts of the excavator, responsible for supporting and controlling the walking function of the excavator's upper structure. However, the long-term operation of the excavator can easily cause the bridge box temperature to rise, resulting in failure and inability to operate. Therefore, in order to reduce the failure rate of the excavator, high temperature alarm for the bridge box is an urgent problem to be solved.

[0066] In the prior art, the high temperature alarm method for the excavator bridge box is usually to install a temperature sensor near the key components of the bridge box. When the temperature sensor detects that the temperature of the key components exceeds the safety threshold, a warning is issued to remind the operator to check or take measures.

[0067] However, the high temperature alarm method of the excavator bridge box in the prior art requires special electrical devices such as electric slip rings when installing the temperature sensor, and the temperature sensor is installed on the lower part of the excavator and is separated from the electrical system of the upper part. The complicated wiring increases labor costs and material costs, and on the other hand, it also increases the failure rate of the bridge box.

[0068] Based on this, the present application proposes a high temperature alarm method, device, equipment medium and product for an excavator bridge box. Since the operating parameters of the engineering machinery that affect the bridge box temperature are often dynamically changing, and they have a complex nonlinear relationship with the bridge box temperature, they cannot be accurately modeled using traditional linear models. However, fuzzy logic control theory relies on fuzzy processing of these engineering machinery operating parameters and mapping them into fuzzy states such as "low", "medium" and "high", so as to flexibly handle temperature changes under different working conditions and determine the final real-time temperature of the excavator bridge box. Specifically, by using fuzzy logic, multiple fuzzy sets corresponding to the temperature of the excavator bridge box, the membership degree corresponding to each fuzzy set, and preset fuzzy rules are established. Then, the target membership degree and target heating rate level of the corresponding excavator are obtained according to the multiple engineering machinery operating parameters of the excavator obtained in real time. After that, the defuzzification method is used to obtain the specific target heating rate, and the temperature of the excavator bridge box is determined in combination with the preset initial temperature and the operating time of the excavator. Finally, by setting the alarm temperature threshold, when the calculated temperature of the excavator bridge box is greater than or equal to this threshold, an alarm will be triggered to remind the operator to take measures to avoid damage or failure of the bridge box due to overheating. The accurate prediction of the temperature of the excavator bridge box is achieved, which helps to take preventive measures before the bridge box temperature is too high, reduces the failure rate of the bridge box, and thus improves the reliability and service life of the excavator.

[0069] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0070] Figure 1 Schematic diagram of the process of the high temperature alarm method of the excavator bridge box provided in the embodiment of the present application Figure 1 .like Figure 1 As shown, the method includes:

[0071] S101. When the excavator is running, a plurality of engineering machinery operating parameters of the excavator are obtained.

[0072] It should be noted that multiple engineering machinery operating parameters include the gear position of the axle box, the engine speed and the opening of the travel valve core.

[0073] The gear position of the axle box is the gear position in the excavator transmission system, usually including "high gear" and "low gear".

[0074] The engine speed is the engine's rotation speed per minute. It is an important parameter of the excavator's power output, and the engine speed is directly proportional to the power output.

[0075] The travel valve core opening refers to the opening of the travel valve core in the hydraulic system of the excavator that controls the flow of hydraulic oil, thereby controlling the acceleration, deceleration and direction change of the excavator during travel.

[0076] It can be understood that through the real-time collection of multiple construction machinery operating parameters, the current working status of the excavator can be accurately reflected, providing a rich data source for subsequent temperature calculations and improving the accuracy and real-time performance of temperature prediction.

[0077] S102, determining a target membership degree and a target heating rate level of the excavator according to a plurality of fuzzy sets, the membership degree corresponding to each fuzzy set, preset fuzzy rules, and a plurality of engineering machinery operating parameters.

[0078] Among them, the fuzzy set refers to the fuzzy set formed by the operating parameters of the construction machinery; the membership degree corresponding to each fuzzy set refers to the degree to which the operating parameter belongs to the fuzzy set; the preset fuzzy rules are used to express the relationship between the fuzzy set and the heating rate level.

[0079] For example, for the operating parameters of the construction machinery in this embodiment, the fuzzy set can divide the operating parameters into "extremely low", "low", "medium", "high" and "extremely high", and the corresponding membership degree of each fuzzy set can be "0.4", "0.3", "0.6", "0.5" and "0.8", and the preset fuzzy rule can be "If the gear is low and the engine speed is low and the travel valve core opening is large, the heating rate level is medium", or it can be "If the gear is high and the engine speed is high and the travel valve core opening is large, the heating rate level is fast".

[0080] It can be understood that through fuzzy logic, multiple parameters of complex, nonlinear relationships are converted into fuzzy sets for processing, thereby establishing multiple fuzzy sets, the membership corresponding to each fuzzy set, and preset fuzzy rules. In addition, multiple engineering machinery operating parameters are used to determine the target membership and target heating rate level of the excavator. This can effectively cope with complex changes in working conditions, flexibly determine the heating rate level of the excavator bridge box, and improve the prediction accuracy of the temperature of the excavator bridge box.

[0081] In one feasible method, the specific process of determining the target membership and target heating rate level of the excavator is as follows:

[0082] Firstly, for each construction machinery operating parameter, the target fuzzy set corresponding to the construction machinery operating parameter is determined; then, the target membership of the excavator is calculated according to the membership corresponding to all target fuzzy sets; finally, the target heating rate level corresponding to all target fuzzy sets is determined according to all target fuzzy sets and preset fuzzy rules.

[0083] The calculation processing includes any of the following: taking the maximum value, taking the minimum value, taking the average value;

[0084] For example, assuming that the target fuzzy sets corresponding to the acquired engineering machinery operating parameters are respectively the gear position of the axle box is "low gear", the engine speed is "low speed" and the travel valve core opening is "small opening", and the memberships obtained according to the memberships corresponding to all the target fuzzy sets are respectively the gear position of the axle box is "low gear" with a membership of 0.8, the engine speed is "low speed" with a membership of 0.7, the travel valve core opening is "small opening" with a membership of 0.5, then these memberships are formed into a set, i.e. [0.8, 0.7, 0.5], and calculations are performed in this set. Assuming that the maximum value method is used, the target membership of the excavator can be obtained as 0.8. Furthermore, according to the preset fuzzy rules, the final target heating rate level is obtained as the heating rate is slow, and the membership is 0.8. The specific calculation and processing method can be selected according to the actual situation, and this embodiment does not make specific restrictions here.

[0085] It can be understood that by converting different construction machinery operating parameters into fuzzy sets, parameters under different states can be handled more flexibly, and the fuzzy rule base is used to provide a flexible prediction of the heating rate, which can cope with complex and changeable operating conditions and further provide a data basis for obtaining accurate bridge box temperature values.

[0086] S103, performing defuzzification processing on the target membership degree and the target heating rate level to determine the target heating rate.

[0087] Among them, defuzzification processing is to convert the result of fuzzy reasoning (such as "fast", "medium" or "slow") into a specific numerical output. Commonly used defuzzification processing methods include area center method, maximum membership method, weighted average method, etc. The specific processing method can be selected according to actual conditions, and this embodiment does not make specific restrictions here.

[0088] Continuing with the previous example, assuming that the target heating rate level is slow, the membership is 0.8, and the temperature range corresponding to slow heating rate is [10, 15, 20] (°C / minute), the specific formula is:

[0089]

[0090] Where z is the target heating rate after defuzzification; u i is the membership value; z i is every value in the temperature range.

[0091] Since u is 0.8, then u i The weighted sum of is 2.4, (u i ·zi ) is 0.8 (10+15+20), which is 36. Therefore, the target heating rate is 15°C / min.

[0092] It can be understood that the defuzzification processing step can convert the results of fuzzy logic reasoning into a specific target heating rate, so as to more accurately predict and judge the heating rate of the bridge box, avoid faults such as overheating, and improve the safety and life of the equipment.

[0093] S104, determining the real-time temperature of the excavator bridge box in real time according to the target heating rate, the preset initial temperature and the operating time of the excavator.

[0094] For example, if the target heating rate is 15°C / minute, the preset initial temperature is 20°C, and the excavator is operated for 10 minutes, the integral formula can be used to calculate the excavator axle box temperature. The specific calculation formula can be:

[0095]

[0096] Among them, T(0) is the preset initial temperature; T(t) is the real-time temperature of the excavator bridge box.

[0097] It can be understood that by combining the target heating rate, the preset initial temperature and the running time, the real-time temperature of the bridge box can be accurately calculated, and the temperature can be used as the basis for judging whether an alarm is needed in the future. This method is flexible, real-time and accurate, and can effectively improve the safety and stability of excavator operation.

[0098] S105. When the real-time temperature is greater than or equal to the first preset alarm temperature, output alarm information.

[0099] Among them, the alarm information is used to remind the driver that the excavator bridge box needs to be cooled down.

[0100] It is understandable that when the real-time temperature is greater than or equal to the first preset alarm temperature, it is judged that there is a potential overheating risk, and then an alarm message is output to prompt the driver that the excavator bridge box needs to take relevant measures to cool down, such as reducing the load or working intensity of the excavator, timely replenishing coolant to enhance heat dissipation capacity and optimizing ventilation conditions.

[0101] The high temperature alarm method of the excavator bridge box provided by the present application, by utilizing the processing ability of fuzzy logic for complex nonlinear problems, establishes multiple fuzzy sets corresponding to the temperature of the excavator bridge box, the membership degree corresponding to each fuzzy set and the preset fuzzy rules, and then obtains the corresponding excavator's target membership degree and target heating rate level according to the multiple engineering machinery operating parameters of the excavator obtained in real time; then, the defuzzification method is used to obtain the specific target heating rate, and the temperature of the excavator bridge box is determined in combination with the preset initial temperature and the operating time of the excavator. Finally, by setting the alarm temperature threshold, when the calculated temperature of the excavator bridge box is greater than or equal to this threshold, the alarm will be triggered to remind the operator to take measures to avoid the bridge box oil seal from melting, oil leakage or oil channeling, or bridge box clutch ablation and other faults. Through this method, the temperature of the excavator bridge box can be accurately predicted and the temperature can be monitored, which reduces the failure rate of the bridge box and helps to improve the operating safety, reliability and efficiency of the excavator.

[0102] It should be noted that in order to prevent the dynamic change of temperature from causing frequent triggering of alarm information, hysteresis control can be set for the alarm information. The specific method is as follows:

[0103] When the real-time temperature drops to the second preset alarm temperature, the alarm information will stop being output.

[0104] Wherein, the first preset alarm temperature is greater than the second preset alarm temperature.

[0105] It should be noted that in order to prevent the dynamic change of the bridge box temperature from causing frequent alarm triggering, it is assumed that the first preset alarm temperature for the alarm triggering is 70°C. When the temperature rises to 70°C, the alarm is triggered; but if the temperature drops slightly to 69.9°C, the alarm will be released. If the temperature rises to 70°C again, the alarm will be triggered again, which will cause frequent alarms and releases. Therefore, in this embodiment, hysteresis control can be set, that is, when the real-time temperature drops to the second preset alarm temperature, the alarm information is stopped from being output.

[0106] For example, if the first preset alarm temperature is 70°C and the second preset alarm temperature is 60°C, when the bridge box temperature rises to 70°C, the alarm action is triggered, but the alarm will be lifted only when the temperature drops below 60°C.

[0107] It can be understood that by setting the first preset alarm temperature and the second preset alarm temperature, frequent alarm state switching can be avoided.

[0108] In one achievable manner, the specific output alarm information includes:

[0109] Display alarm information on the display screen of the excavator;

[0110] Or, control the fault warning light corresponding to the alarm information in the excavator to flash;

[0111] Or, control the excavator to play the preset music corresponding to the alarm information.

[0112] It can be understood that when the real-time temperature is greater than or equal to the first preset alarm temperature, it is judged that there is a potential overheating risk, and then the alarm information is displayed through the excavator's display screen. The fault warning light corresponding to the alarm information in the excavator can also be controlled to flash. The excavator can also be controlled to play the preset music corresponding to the alarm information to help prompt the driver to take relevant measures to cool the bridge box.

[0113] Figure 2 Schematic diagram of the process of the high temperature alarm method of the excavator bridge box provided in the embodiment of the present application Figure 2 This embodiment is in Figure 1 Based on the embodiment, the process of determining the target membership and the target heating rate is described in detail. Figure 2 As shown, including:

[0114] S201. When the excavator is running, obtain the ambient temperature of the environment in which the excavator is located.

[0115] It is understandable that when the excavator is running, the temperature sensor provided on the vehicle body can be used to obtain the ambient temperature of the environment in which the excavator is located.

[0116] S202, determining a target membership degree and a target heating rate level according to a plurality of fuzzy sets, a membership degree corresponding to each fuzzy set, a preset fuzzy rule, a plurality of engineering machinery operating parameters and an ambient temperature.

[0117] It can be understood that by further determining the target membership and target heating rate level based on multiple engineering machinery operating parameters and ambient temperature, using multiple fuzzy sets, the membership corresponding to each fuzzy set, and preset fuzzy rules, the accuracy of the heating rate prediction can be further ensured, thereby helping the excavator bridge box to achieve more precise temperature control.

[0118] It should be noted that the specific implementation process is illustrated by way of example in the above embodiments, and the embodiments of the present application will not be elaborated in detail here.

[0124] S305: Output alarm information.

[0125] S306. Maintain the normal operation of the excavator.

[0126] It should be noted that the specific implementation process is illustrated by way of example in the above embodiments, and the embodiments of the present application will not be elaborated in detail here.

[0127] The high temperature alarm method for the excavator bridge box provided in this application uses fuzzy logic to process complex nonlinear problems, and establishes multiple fuzzy sets and corresponding membership rules for the bridge box temperature. By acquiring the operating parameters of the excavator in real time, the target membership and the heating rate level are calculated, and then the specific heating rate is obtained by using the defuzzification method, and the real-time temperature of the bridge box is predicted in combination with the initial temperature and the operating time. An alarm temperature threshold is set, and when the temperature exceeds the preset threshold, an alarm is triggered to remind the operator to take measures to prevent failures caused by overheating, otherwise the excavator is kept in normal operation. This method improves the accuracy of temperature prediction and monitoring, reduces the failure rate, and enhances the operating safety and reliability of the excavator.
