Description

Technical Field

[0001] The present application relates to the field of gantry crane technology, and in particular to a gantry crane chain break detection method, system, intelligent terminal and storage medium. Background Art

[0002] Gantry crane is an important container loading and unloading equipment in port terminals and other storage yards. The four-wheel drive gantry crane has the advantages of high utilization rate, strong stacking capacity, good maneuverability and flexible transfer.

[0003] In the relevant technology, the advantage of the four-wheel drive gantry crane over the two-wheel drive gantry crane is that the trolley mechanism of the four-wheel drive gantry crane operates stably, and the driving device and the running wheels are connected by four trolley chains, so that the power generated by the driving device is effectively transmitted to the running wheels to realize the movement of the equipment. When a trolley drive fails or the chain breaks, it still has the ability to move the trolley.

[0004] Regarding the above-mentioned related technologies, during actual use, when a driving chain of a trolley of a four-wheel drive gantry crane breaks, the four-wheel drive gantry crane continues to work normally, resulting in the driver and maintenance personnel being unable to promptly know that the four-wheel drive gantry crane has a broken chain, resulting in a delay in fault detection. There is still room for improvement. Summary of the invention

[0005] In order to improve the timeliness of detecting broken chain faults of gantry cranes, the present application provides a gantry crane broken chain detection method, system, intelligent terminal and storage medium.

[0006] In a first aspect, the present application provides a gantry crane chain break detection method, which adopts the following technical solution: A gantry crane chain break detection method, comprising: Get the start trigger information of the gantry crane; Determine the normal operating parameter information of the preset trolley based on the start trigger information, and control the preset monitoring device to monitor the trolley to generate actual operating parameter information; Analyze and determine parameter gap information based on actual operating parameter information and normal operating parameter information; Determine whether the parameter gap information meets the requirements of the preset alarm threshold information; If it does not meet the requirements, the normal operating parameter information of the trolley will continue to be determined, and the monitoring device will continue to monitor the trolley to generate actual operating parameter information for cyclic monitoring; If it meets the requirements, a prompt will be given according to the preset fault alarm information.

[0007] By adopting the above technical scheme, after the gantry crane is started, the normal operating parameter information of the trolley is determined, and the actual operating parameter information of the trolley is detected, so as to analyze the parameter difference information based on the two. When it is determined that the parameter difference information meets the requirements of the alarm threshold information, it means that although the trolley is operating normally, the chain on the trolley is broken, causing the gap between the operating parameters of the trolley and the normal operating parameters to be too large. Therefore, according to the fault alarm prompt information, a prompt is given to enable personnel to promptly discover the broken chain of the trolley, thereby improving the timeliness of the discovery of the broken chain fault of the gantry crane.

[0008] Optionally, the step of determining the normal operating parameter information of the preset vehicle based on the start trigger information includes: Acquire the first working mode information and running speed information of the vehicle based on the start trigger information; Determine basic adjustment parameter information of the vehicle according to the first working mode information, the running speed information and the preset mode adjustment parameter relationship information; Obtain the working environment information of the large vehicle; Adjust the basic adjustment parameter information according to the working environment information to determine the actual adjustment parameter information; The normal operating parameter information is determined by analyzing the actual adjustment parameter information and the preset normal parameter information.

[0009] By adopting the above technical scheme, the actual adjustment parameter information of the truck is determined according to the working mode, running speed and working environment of the taxi, and then the normal operating parameter information that the truck should have at this time is determined according to the actual adjustment parameter information and the normal parameter information. By adjusting the normal operating parameter information in real time, the accuracy of judging whether the truck is broken is guaranteed.

[0010] Optionally, the step of adjusting the basic adjustment parameter information according to the working environment information to determine the actual adjustment parameter information includes: Analyze and determine the real-time load information and road surface roughness information of the truck based on the working environment information; Determining load adjustment parameter information according to real-time load information and preset load parameter relationship information; Determining the smoothness adjustment parameter information according to the road surface smoothness information and the preset smoothness parameter relationship information; The actual adjustment parameter information is determined by analyzing the basic adjustment parameter information, the load adjustment parameter information and the flatness adjustment parameter information.

[0011] By adopting the above technical scheme, the load adjustment parameter information is determined according to the load of the truck, and the flatness adjustment parameter information is determined according to the flatness of the road surface, so as to obtain the actual adjustment parameter information by comprehensively considering the influence of the truck load and road conditions on the truck operation parameters, so that the normal operation parameter information of the truck is more in line with the actual working state, thereby improving the accuracy of judging whether the truck is broken.

[0012] Optionally, the step of controlling a preset monitoring device to monitor the vehicle and generate actual operating parameter information includes: Acquiring the second working mode information of the vehicle based on the start trigger information; Determining monitoring delay information according to the second working mode information and preset mode delay relationship information; Get the actual running time information of the vehicle; Determine whether the actual running time information meets the requirements of monitoring delay information; If it does not meet the requirement, the actual running time information of the vehicle will continue to be obtained for cyclic judgment; If it meets the requirements, the control monitoring device will monitor the vehicle and generate actual operating parameter information.

[0013] By adopting the above technical scheme, the monitoring delay information is determined according to the working mode of the truck. After the actual running time information reaches the monitoring delay information, the monitoring device is controlled to monitor the truck to generate actual running parameter information, thereby preventing the system from misjudging due to the instantaneous high value of the running parameter when the truck starts, thereby improving the accuracy of judging whether the truck is broken.

[0014] Optionally, the step of controlling the monitoring device to monitor the vehicle and generate actual operating parameter information includes: Obtain the vehicle's traveling smoothness information; Determine whether the travel flatness information meets the requirements of preset flatness information; If it meets the requirements, the monitoring device is controlled to monitor the vehicle according to the preset interval detection method to generate actual operation parameter information; If it does not meet the requirements, the monitoring device is controlled according to the preset real-time detection method to monitor the vehicle and generate actual operating parameter information.

[0015] By adopting the above technical scheme, when the traveling flatness information meets the requirements of the flatness information, it means that the truck is traveling on a relatively flat road at this time, and the external environment has little impact on the truck chain breakage. Therefore, the actual operating parameter information can be detected at intervals. When it does not meet the requirements, it means that the road surface is uneven and it is easy to cause the truck chain breakage. Therefore, the actual operating parameter information is detected in real time, thereby improving the accuracy of the actual operating parameter information.

[0016] Optionally, the step of analyzing and determining parameter gap information according to actual operation parameter information and normal operation parameter information includes: Get the tire pressure detection information of the vehicle; Determine whether the tire pressure detection information meets the preset abnormal tire pressure trigger information requirements; If not, the difference between the normal operating parameter information and the actual operating parameter information is calculated, and the calculated difference is defined as parameter gap information; If it is in compliance, abnormal tire pressure information is obtained, and actual operating parameter information is verified according to the abnormal tire pressure information to generate verification operating parameter information; The difference between the normal operating parameter information and the verification operating parameter information is calculated, and the calculated difference is defined as parameter gap information.

[0017] By adopting the above technical solution, when it is determined that the tire pressure detection information of the large vehicle meets the requirements of the abnormal tire pressure trigger information, it indicates that there are parameter abnormalities caused by abnormal tire pressure in the actual operating parameter information. Therefore, the actual operating parameter information is verified according to the abnormal tire pressure information, and the difference between the verification parameter information and the normal operating parameter information is calculated to obtain the parameter gap information, thereby improving the accuracy of the parameter gap information.

[0018] Optionally, the step of verifying the actual operating parameter information according to the abnormal tire pressure information to generate the verified operating parameter information includes: acquiring associated tire pressure information based on the abnormal tire pressure information; Analyze and determine the reference operating parameter information and the parameter information to be verified according to the abnormal tire pressure information, the associated tire pressure information and the actual operating parameter information; Determining calibration coefficient information according to abnormal tire pressure information and preset tire pressure calibration coefficient relationship information; Analyze and determine the calibration parameter information based on the normal operating parameter information, the benchmark operating parameter information and the calibration coefficient information; The calibration operation parameter information is determined by analyzing the parameter information to be calibrated and the calibration parameter information.

[0019] By adopting the above technical scheme, the verification coefficient information is determined according to the abnormal tire pressure information, so as to determine the extra parameters of the abnormal tire according to the normal operating parameter information and the benchmark operating parameter information, and then the product of the verification coefficient information and the extra parameters is calculated to obtain the verification parameter information, and then the sum of the parameter information to be verified and the verification parameter information is calculated to obtain the verification operating parameter information, so as to calculate the correct operating parameters according to the correlation between the operating parameters of the running wheels on both sides when the tire pressure is insufficient, thereby improving the accuracy of the verification operating parameter information.

[0020] In the second aspect, the present application provides a gantry crane chain break detection system, which adopts the following technical solution: A gantry crane chain break detection system, comprising: An acquisition module is used to acquire start trigger information; A memory, used to store a program of a gantry crane chain break detection method as described in any one of the above items; The program in the processor and the memory can be loaded and executed by the processor to implement a gantry crane chain break detection method as described in any one of the above items.

[0021] By adopting the above technical solution, the processor loads and executes a program of a gantry crane chain break detection method stored in the memory, thereby controlling the acquisition module to obtain a series of data related to the gantry crane chain break detection, and then analyzing the parameter gap information based on the actual operating parameter information of the trolley and the normal operating parameter information. When it is determined that the parameter gap information meets the requirements of the alarm threshold information, the personnel are promptly reminded that the trolley chain is broken, thereby improving the timeliness of the gantry crane chain break fault detection.

[0022] In a third aspect, the present application provides a smart terminal, which adopts the following technical solution: An intelligent terminal comprises a memory and a processor, wherein the memory stores a computer program which can be loaded by the processor and executes a gantry crane chain break detection method as described in any one of the above items.

[0023] By adopting the above technical solution and operating the intelligent terminal, the processor is made to load and execute a computer program of a gantry crane chain break detection method stored in the memory, thereby analyzing the parameter gap information based on the actual operating parameter information of the trolley and the normal operating parameter information. When it is determined that the parameter gap information meets the requirements of the alarm threshold information, the personnel are promptly reminded that the trolley chain is broken, thereby improving the timeliness of the detection of the gantry crane chain break fault.

[0024] In a fourth aspect, the present application provides a computer storage medium capable of storing corresponding programs, which has the characteristics of facilitating the improvement of the timeliness of the detection of the broken chain fault of the gantry crane, and adopts the following technical solutions: A computer-readable storage medium stores a computer program that can be loaded by a processor and execute any of the above-mentioned gantry crane chain break detection methods.

[0025] By adopting the above technical solution, a computer program for a gantry crane chain break detection method is stored in a computer-readable storage medium, so that the processor loads and executes the computer program in the storage medium, thereby analyzing the parameter gap information based on the actual operating parameter information of the trolley and the normal operating parameter information, and when it is determined that the parameter gap information meets the requirements of the alarm threshold information, the personnel are promptly reminded that the trolley chain is broken, thereby improving the timeliness of the detection of the gantry crane chain break fault.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1.

When it is determined that the parameter difference information meets the requirements of the alarm threshold information, it means that although the trolley is operating normally, the chain on the trolley is broken, causing the operating parameters of the trolley to be too different from the normal operating parameters. Therefore, according to the fault alarm prompt information, prompts are given to enable personnel to discover the chain break of the trolley in time, thereby improving the timeliness of the discovery of the gantry crane chain break fault; 2. By determining the monitoring delay information according to the working mode of the trolley, after the actual running time information reaches the monitoring delay information, the monitoring device is controlled to monitor the trolley to generate the actual running parameter information, thereby preventing the instantaneous high value of the running parameter when the trolley starts from causing the system to misjudge, thereby improving the accuracy of judging whether the trolley is broken; 3. When it is determined that the traveling flatness information meets the requirements of the flatness information, it means that the truck is traveling on a relatively flat road at this time, and the external environment has little impact on the truck chain breakage. Therefore, the actual operation parameter information can be detected at intervals. When it does not meet the requirements, it means that the road surface is uneven and it is easy to cause the truck chain breakage. Therefore, the actual operation parameter information is detected in real time to improve the accuracy of the actual operation parameter information. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-Figure 7 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] The embodiment of the present application discloses a method for detecting a broken chain of a four-wheel drive gantry crane trolley, and specifically discloses a monitoring device and a processing terminal. The monitoring device and the processing terminal are connected via a data wire to realize data interaction and control. When the processing terminal receives the start trigger information of the gantry crane, the processing terminal determines the normal operating parameter information of the trolley at this time, and synchronously controls the monitoring device to monitor the trolley to obtain actual operating parameter information, and determines parameter gap information after analyzing the normal operating parameter information and the actual operating parameter information, thereby comparing the parameter gap information with the alarm threshold information. When it is determined that the parameter gap information meets the requirements of the alarm threshold information, it indicates that the operating parameters of the trolley are abnormal and the chain of the trolley is broken. Therefore, personnel are prompted according to the fault alarm information, thereby improving the timeliness of the detection of the broken chain fault of the gantry crane.

[0036] Reference Figure 1 The present application embodiment discloses a gantry crane chain break detection method, comprising the following steps: Step S100: Obtain the start trigger information of the gantry crane.

[0037] The start trigger information refers to the trigger data for starting the gantry crane. When the driver starts the gantry crane, the gantry crane system sends the trigger data to the processing terminal.

[0038] Step S101: Determine the normal operating parameter information of the preset large vehicle based on the start trigger information, and control the preset monitoring device to monitor the large vehicle to generate actual operating parameter information.

[0039] Among them, when the processing terminal receives the start trigger information, the processing terminal responds to the start trigger information, determines the normal operating parameter information of the large vehicle, and synchronously controls the monitoring device to monitor the large vehicle to generate actual operating parameter information, providing data support for the subsequent determination of whether the large vehicle is broken.

[0040] The trolley is a device used to control the movement of the entire gantry crane, including four traveling wheels. The driving device drives the traveling wheels to rotate through four chains. The normal operating parameter information refers to the operating parameters of the trolley when there is no broken chain at this time, including the torque value and current value of the driving device driving the traveling wheels. For specific determination methods, refer to Figure 2 The monitoring device refers to a device for monitoring the operating parameters of the trolley. The trolley inverter can be used to monitor the torque and current of the trolley. The actual operating parameter information refers to the actual operating parameters during the operation of the trolley, including the trolley torque value and current value, which are detected by the monitoring device. For specific methods, refer to Figure 4 steps.

[0041] Step S102: Analyze and determine parameter gap information based on the actual operation parameter information and the normal operation parameter information.

[0042] The parameter gap information refers to the gap between the actual operating parameters of the vehicle and the normal operating parameters. It is determined by the processing terminal after analyzing the actual operating parameter information and the normal operating parameter information. The specific analysis method is referred to Figure 6 steps.

[0043] Step S103: determining whether the parameter difference information meets the requirements of the preset alarm threshold information.

[0044] The alarm threshold information refers to the parameter difference value when an alarm is required, and the requirement of the alarm threshold information refers to the parameter difference value not less than the corresponding alarm threshold information, which are all stored in the processing terminal by the operator.

[0045] The processing terminal determines whether the parameter difference corresponding to the parameter gap information is not less than the parameter difference corresponding to the alarm threshold information, thereby determining whether the truck has a broken chain.

[0046] Step S1031: If it does not meet the requirements, continue to determine the normal operating parameter information of the large vehicle, and continue to control the monitoring device to monitor the large vehicle to generate actual operating parameter information for cyclic monitoring.

[0047] Among them, if the processing terminal determines that the parameter difference corresponding to the parameter gap information is smaller than the parameter difference corresponding to the alarm threshold information, it indicates that the actual operating parameters of the trolley are slightly different from the normal operating parameters. At this time, it can be determined that the trolley is not broken. Therefore, the normal operating parameter information of the trolley continues to be dynamically adjusted, and the monitoring device continues to be controlled to monitor the trolley to generate actual operating parameter information, thereby continuously monitoring the broken chain of the trolley.

[0048] Step S1032: If it meets the requirements, a prompt is given according to the preset fault alarm information.

[0049] Among them, if the processing terminal determines that the parameter difference corresponding to the parameter gap information is not less than the parameter difference corresponding to the alarm threshold information, it means that the actual operating parameters of the trolley are significantly different from the normal operating parameters. When the trolley is broken, the torque value and the current value become smaller, thereby causing the parameter difference to become larger. Therefore, it is determined that the trolley is broken, and prompts are given according to the fault alarm information, so that personnel can promptly discover the broken chain failure of the trolley.

[0050] Fault alarm information refers to prompt information that reminds personnel of a broken chain failure of a large vehicle. In one embodiment, only sound and text may be used to remind personnel of the broken chain failure of the large vehicle. In another embodiment, the running tires to which actual operating parameters having a large parameter difference belong are analyzed, thereby providing an alarm prompt with detailed tire properties.

[0051] Reference Figure 2 The step of determining the normal operating parameter information of the preset vehicle based on the start trigger information includes: Step S200: Acquire the first working mode information and running speed information of the vehicle based on the start trigger information.

[0052] Among them, the first working mode information refers to the working mode of the truck, including the truck running at 0 degrees, the hoisting gear unlocking status, the four-wheel drive mode, etc., which is selected by the driver in the gantry crane system and called from the gantry crane system by the processing terminal when the processing terminal receives the start trigger information.

[0053] The running speed information refers to the running speed of the vehicle. After the processing terminal receives the start trigger information, the processing terminal controls the speed sensor to detect the running speed of the vehicle in real time and sends it to the processing terminal.

[0054] Step S201: determining basic adjustment parameter information of the vehicle according to the first working mode information, the running speed information and the preset mode adjustment parameter relationship information.

[0055] Among them, the mode adjustment parameter relationship information refers to the corresponding relationship between the adjustment parameters when running at different speeds in different modes. For example, in the 0-degree operating mode, when the speed is at the starting speed, the adjustment parameter is 1.5, and when the speed is at the increasing speed, the adjustment parameter is 1.3, and when the speed is at a constant speed, the adjustment parameter is 1.1. The maximum adjustment parameter of the sling unlocking mode is 1.8, which is the same as the 0-degree operating mode according to the change in speed. The maximum adjustment parameter of the four-wheel drive mode is 1.7, which is the same as the 0-degree operating mode according to the speed ratio. The operator forms a mapping table by matching the working mode, operating speed and adjustment parameter one by one.

[0056] The basic adjustment parameter information refers to the adjustment coefficient of the normal operating parameters when only the vehicle's own state is considered. The processing terminal searches for the basic adjustment parameter information in the mapping table corresponding to the mode adjustment parameter relationship information according to the mode corresponding to the first working mode information and the speed corresponding to the operating speed information.

[0057] Step S202: Obtain the working environment information of the vehicle.

[0058] Among them, the working environment information refers to the external environmental factors that affect the truck, including the road surface flatness and the truck load condition. The road surface flatness is detected by the flatness sensor, and the truck load condition is detected by the load sensor installed on the hoist.

[0059] Step S203: adjusting the basic adjustment parameter information according to the working environment information to determine the actual adjustment parameter information.

[0060] The actual adjustment parameter information refers to the coefficients of adjusting the normal parameters by comprehensively considering the vehicle's own attributes and the external environment attributes. It is obtained by the processing terminal based on the parameters corresponding to the basic adjustment parameter information and considering the data corresponding to the working environment information. For specific methods, refer to Figure 3 steps.

[0061] Step S204: Analyze and determine normal operating parameter information based on the actual adjustment parameter information and the preset normal parameter information.

[0062] The normal parameter information refers to the torque value and current value of the vehicle under normal conditions, and the specific values ​​are determined by the operator according to the actual situation. The normal operating parameter information in this step is consistent with the normal operating parameter information in step S101, and is obtained by the processing terminal by respectively calculating the product of the adjustment coefficient corresponding to the actual adjustment parameter information and the torque value and current value corresponding to the normal parameter information.

[0063] Reference Figure 3 The step of adjusting the basic adjustment parameter information according to the working environment information to determine the actual adjustment parameter information includes: Step S300: Analyze and determine the real-time load information and road surface roughness information of the truck based on the working environment information.

[0064] Among them, the real-time load information refers to the load condition of the truck, and the road surface flatness information refers to the flatness of the road surface on which the truck is traveling, which is identified and called by the processing terminal in the data corresponding to the working environment information.

[0065] Step S301: Determine load adjustment parameter information according to real-time load information and preset load parameter relationship information.

[0066] Among them, the load parameter relationship information refers to the corresponding relationship between the truck load and the additional adjustment parameters. The truck load is proportional to the additional adjustment parameters. The larger the truck load, the larger the additional adjustment parameters. The operator matches the two one by one to form a mapping table.

[0067] The load adjustment parameter information refers to the additional parameters that need to be adjusted due to the vehicle load, and is obtained by the processing terminal by searching in the mapping table corresponding to the load parameter relationship information according to the load corresponding to the real-time load information.

[0068] Step S302: Determine the smoothness adjustment parameter information according to the road surface smoothness information and the preset smoothness parameter relationship information.

[0069] Among them, the flatness parameter relationship information refers to the correspondence between the road surface flatness and the additional adjustment parameter. The flatness is proportional to the additional adjustment parameter. The larger the flatness, the larger the additional adjustment parameter. The operator forms a mapping table by matching the two one by one.

[0070] The smoothness adjustment parameter information refers to additional parameters that need to be adjusted due to the road surface smoothness, and is obtained by searching the mapping table corresponding to the smoothness parameter relationship information by the processing terminal according to the smoothness corresponding to the road surface smoothness information.

[0071] Step S303: Analyze and determine actual adjustment parameter information according to the basic adjustment parameter information, the load adjustment parameter information and the flatness adjustment parameter information.

[0072] The actual adjustment parameter information in this step is consistent with the actual adjustment parameter information in step S203, and is obtained by adding the additional adjustment parameters corresponding to the load adjustment parameter information and the additional adjustment parameters corresponding to the flatness adjustment parameter information to the parameters corresponding to the basic adjustment parameter information by the processing terminal.

[0073] Reference Figure 4 The steps of controlling the preset monitoring device to monitor the vehicle and generate actual operating parameter information include: Step S400: obtaining the second working mode information of the vehicle based on the start trigger information.

[0074] Among them, the second working mode information in this step is consistent with the first working mode information in step S200, and will not be repeated here.

[0075] Step S401: Determine monitoring delay information according to the second working mode information and preset mode delay relationship information.

[0076] Among them, the mode delay relationship information refers to the correspondence between the vehicle working mode and the monitoring delay time. The delay when running at 0 degrees is relatively short, just a few seconds. The delay when the spreader is unlocked and in four-wheel drive mode is longer, for example, tens of seconds. The specific value is determined by the operator according to the actual situation, and the delay and mode are matched one by one to form a database.

[0077] The monitoring delay information refers to the time from the start of the gantry crane to the monitoring of the trolley operating parameters by the monitoring device, which is obtained by searching the mapping table corresponding to the mode delay relationship information according to the working mode corresponding to the second working mode information by the processing terminal.

[0078] Step S402: Obtain the actual running time information of the vehicle.

[0079] The actual operation time information refers to the actual operation time of the trolley, which is obtained by the timer when the gantry crane is started.

[0080] Step S403: Determine whether the actual running time information meets the requirements of monitoring delay information.

[0081] The requirement of monitoring delay information refers to the time value corresponding to the monitoring delay information, which is stored in the processing terminal by the operator. The processing terminal determines whether the time corresponding to the actual operation time information is equal to the time value corresponding to the monitoring delay information, thereby determining whether the monitoring device can be controlled to monitor the operation parameters of the vehicle.

[0082] Step S4031: If not, continue to obtain the actual running time information of the vehicle for cyclic judgment.

[0083] Among them, if the processing terminal determines that the time corresponding to the actual running time information is not equal to the time value corresponding to the monitoring delay information, it means that the vehicle is still in the delay stage. At this time, the vehicle has just started, and the instantaneous torque value and current value will be too large. At this time, the detection is prone to misjudgment. Therefore, the actual running time information of the vehicle continues to be detected, so as to continue to pay attention to the running time of the vehicle.

[0084] Step S4032: If it meets the requirements, the monitoring device is controlled to monitor the vehicle and generate actual operating parameter information.

[0085] If the processing terminal determines that the time corresponding to the actual operation time information is equal to the time value corresponding to the monitoring delay information, it indicates that the vehicle is in a stable stage and is not likely to have excessive instantaneous torque and current values. Therefore, the monitoring device is controlled to monitor the vehicle to generate actual operation parameter information. For specific methods, refer to Figure 5 steps.

[0086] Reference Figure 5The steps of controlling the monitoring device to monitor the vehicle and generate actual operating parameter information include: Step S500: Obtaining the traveling smoothness information of the vehicle.

[0087] The traveling smoothness information in this step is consistent with the road surface smoothness information in step S300, and will not be elaborated here.

[0088] Step S501: Determine whether the traveling flatness information meets the preset flatness information requirement.

[0089] Among them, the flatness information refers to the flatness of the road surface when it is flat. The specific value is determined by the operator according to the actual situation. The requirement of the flatness information refers to the flatness not greater than the flatness corresponding to the flatness information, which is stored in the processing terminal by the operator.

[0090] By processing the terminal, it is determined whether the flatness corresponding to the traveling flatness information is not greater than the flatness corresponding to the flat flatness information, thereby determining whether the road surface on which the truck is traveling is likely to cause chain breakage.

[0091] Step S5011: If it meets the requirements, the monitoring device is controlled according to the preset interval detection method to monitor the vehicle and generate actual operation parameter information.

[0092] Among them, if the processing terminal determines that the flatness corresponding to the traveling flatness information is not greater than the flatness corresponding to the flat flatness information, it means that the road surface on which the truck is traveling is relatively flat and it is not easy to cause the truck chain to break. Therefore, the monitoring device is controlled according to the interval detection method to monitor the truck and generate actual operating parameter information.

[0093] The interval detection method refers to a method of detecting the operating parameters once every certain period of time. The specific time interval is determined by the operator based on the actual situation.

[0094] Step S5012: If not, the monitoring device is controlled to monitor the vehicle and generate actual operating parameter information according to a preset real-time detection method.

[0095] Among them, if the processing terminal determines that the flatness corresponding to the traveling flatness information is greater than the flatness corresponding to the flat flatness information, it means that the road surface on which the truck is traveling is uneven, which may easily cause the chain of the truck to break. Therefore, the monitoring device is controlled according to the real-time detection method to monitor the truck and generate actual operating parameter information.

[0096] The real-time detection method refers to a method of detecting the vehicle operation parameters in real time, which is stored in the processing terminal by the operator.

[0097] Reference Figure 6The steps of analyzing and determining parameter gap information based on actual operating parameter information and normal operating parameter information include: Step S600: Obtain tire pressure detection information of the vehicle.

[0098] Among them, the tire pressure detection information refers to the tire pressure of the vehicle's running tires, including the tire pressure of four running tires, which is detected by the tire pressure sensor and sent to the processing terminal.

[0099] Step S601: Determine whether the tire pressure detection information meets the preset abnormal tire pressure trigger information requirements.

[0100] Among them, abnormal tire pressure trigger information refers to trigger data of abnormal tire pressure, and the requirement of abnormal tire pressure trigger information refers to the consistency of trigger data corresponding to the abnormal tire pressure trigger information, both of which are stored in the processing terminal by the operator.

[0101] The processing terminal analyzes the tire pressure relative to the running tire in the tire pressure detection information, thereby determining whether the tire pressure corresponding to the tire pressure detection information is consistent with the trigger data corresponding to the abnormal tire pressure trigger information, thereby determining whether the tire pressure of the running tire is abnormal.

[0102] Step S6011: If not, the difference between the normal operating parameter information and the actual operating parameter information is calculated, and the calculated difference is defined as parameter gap information.

[0103] Among them, if the processing terminal determines that the tire pressure corresponding to the tire pressure detection information is inconsistent with the trigger data corresponding to the abnormal tire pressure trigger information, it indicates that the tire pressure difference of the relative running tires is not large and will not affect the operating parameters. Therefore, the difference between the torque value and current value corresponding to the normal operating parameter information and the torque value and current value corresponding to the actual operating parameter information is calculated, and the absolute value is taken to obtain the parameter difference information.

[0104] Step S6012: If it is in compliance, abnormal tire pressure information is obtained, and the actual operating parameter information is verified according to the abnormal tire pressure information to generate verification operating parameter information.

[0105] Among them, if the processing terminal determines that the tire pressure corresponding to the tire pressure detection information is consistent with the trigger data corresponding to the abnormal tire pressure trigger information, it indicates that the tire pressure difference of the relative running tires is large. At this time, the running tire with a smaller tire pressure needs a larger operating parameter to maintain moving because of the larger contact area with the ground, while the operating parameters of the relative running tire are reduced. At this time, the actual operating parameter information detected cannot be directly used as a comparison value to differ from the normal running parameters. Although the increased parameters of the abnormal running tire are not equal to the decreased parameters of the normal running tire, there is a certain connection between the two, and the overall operating parameters are increased. Therefore, it is necessary to verify the actual operating parameter information according to the abnormal tire pressure information and generate the verification operating parameter information to provide data support for the subsequent determination of the parameter gap information.

[0106] Verification of operating parameters refers to the operation parameters of the vehicle after verification when considering abnormal tire pressure. For specific methods, refer to Figure 7 steps.

[0107] Step S60121: Calculate the difference between the normal operating parameter information and the verification operating parameter information, and define the calculated difference as parameter gap information.

[0108] After the processing terminal determines the verification operation parameter information, the processing terminal calculates the difference between the torque value and current value corresponding to the normal operation parameter information and the torque value and current value corresponding to the verification operation parameter information, and obtains the absolute value.

[0109] Reference Figure 7 The step of verifying the actual operating parameter information according to the abnormal tire pressure information and generating the verified operating parameter information includes: Step S700: Acquire associated tire pressure information based on abnormal tire pressure information.

[0110] The associated tire pressure information refers to the tire pressure of the running tire opposite to the running tire corresponding to the abnormal tire pressure information, which is obtained by the processing terminal calling the tire pressure of the running tire opposite to the running tire according to the attribute of the running tire corresponding to the abnormal tire pressure information.

[0111] Step S701: Analyze and determine reference operating parameter information and parameter information to be verified based on abnormal tire pressure information, associated tire pressure information and actual operating parameter information.

[0112] Among them, the benchmark operating parameter information refers to the control operating parameters during the operating parameter verification, which is actually the operating parameters of the running tire with lower tire pressure. The processing terminal obtains the operating parameters of the corresponding running tire in the parameters corresponding to the actual operating parameter information based on the running tire properties corresponding to the abnormal tire pressure information.

[0113] The parameter information that needs to be verified refers to the operating parameters that need to be verified, which are actually the operating parameters of the running tire relative to the abnormal running tire. The processing terminal obtains the operating parameters of the corresponding running tire in the parameters corresponding to the actual operating parameter information based on the running tire properties corresponding to the associated tire pressure information.

[0114] Step S702: Determine the calibration coefficient information according to the abnormal tire pressure information and the preset tire pressure calibration coefficient relationship information.

[0115] Among them, the tire pressure verification coefficient relationship information refers to the corresponding relationship between the tire pressure and the verification coefficient. The smaller the tire pressure, the larger the verification coefficient. The verification coefficient is greater than 0 and less than 1 to ensure that the increase in the operating parameter is greater than the decrease in the value. The operator matches the two one by one to form a mapping table.

[0116] The calibration coefficient information refers to the coefficient for calibrating the operating parameters to be calibrated, and is obtained by searching the mapping table corresponding to the tire pressure calibration coefficient relationship information by the processing terminal according to the tire pressure corresponding to the abnormal tire pressure information.

[0117] Step S703: Analyze and determine the calibration parameter information based on the normal operation parameter information, the benchmark operation parameter information and the calibration coefficient information.

[0118] Among them, the verification parameter information refers to the parameters used to verify the parameter information that needs to be verified. The processing terminal calculates the difference between the parameters corresponding to the benchmark operating parameter information and the parameters corresponding to the normal operating parameter information to obtain the increased parameters of the abnormal tire, and then calculates the product of the difference and the coefficient corresponding to the verification coefficient information to obtain the reduced parameters of the normal tire.

[0119] Step S704: Analyze and determine the verification operation parameter information based on the parameter information to be verified and the verification parameter information.

[0120] Among them, after the processing terminal obtains the verification parameter information, the processing terminal calculates the sum of the parameters corresponding to the parameter information to be verified and the parameters corresponding to the verification parameter information to obtain the verification operating parameter information, thereby compensating for the operating parameters of the normal tire that are reduced due to the abnormal tire, and avoiding the misjudgment of normal tire chain break due to the reduction of operating parameters.
