[0062] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0063] See below Figure 1 , Figure 1 A flowchart of a fault information management method provided in an embodiment of the present application.

[0064] Specific steps may include:

[0065] S101: receiving a current diagnostic code sent by a control module;

[0066] Among them, this embodiment can be applied to the interactive module of the fault diagnosis system, and the fault diagnosis system also includes n acquisition modules and n control modules, and the acquisition modules correspond to the control modules one by one, and each of the acquisition modules is connected to the corresponding equipment component, and the acquisition module is used to transmit the working parameters of the equipment component to the corresponding control module. Figure 2 , Figure 2 This is a structural diagram of a fault diagnosis system provided by an embodiment of the present application, which shows the connection relationship between acquisition modules 1~n, control modules 1~n and interaction modules. The above working parameters can be parameters collected by sensors in equipment components, and the diagnosis objects of the fault diagnosis system include multiple equipment components.

[0067] After the control module receives the current working parameters transmitted by the acquisition module, the control module can determine whether the current working parameters are abnormal; if there is an abnormality, a corresponding diagnostic code is generated. The current diagnostic code received by the interactive module is a diagnostic code generated by the control module after detecting that the current working parameters transmitted by the acquisition module are abnormal. The control module can set a rule for judging whether the working parameters are abnormal, so as to make an abnormal judgment on the current working parameters based on the rule. The diagnostic code can be a code generated according to the diagnostic code coding rule.

[0068] S102: determining a corresponding target cache queue from all cache queues according to the diagnostic code type of the current diagnostic code;

[0069] In this embodiment, a plurality of cache queues may be provided, each cache queue being used to store diagnostic codes of a corresponding diagnostic code type, so that fault information can be classified and stored according to the diagnostic code type.

[0070] The interactive module can parse the received current diagnostic code to determine the diagnostic code type to which it belongs; according to the diagnostic code type obtained by parsing, this embodiment can search for the target cache queue corresponding to the diagnostic code type in all cache queues. In the above manner, it is ensured that the fault information can be accurately stored in the corresponding cache queue according to the type, so as to realize the classified storage and efficient management of the fault information, and provide strong support for subsequent fault query and analysis.

[0071] S103: If the current diagnosis code is not stored in the target cache queue, storing the current diagnosis code in the target cache queue;

[0072] Among them, this embodiment can determine whether the current diagnostic code received by S101 has been stored in the target cache queue; if the current diagnostic code is not stored in the target cache queue, the current diagnostic code is stored in the target cache queue to perform a diagnostic code display operation; if the current diagnostic code is already stored in the target cache queue, the storage process of the current diagnostic code can be exited (that is, the current diagnostic code received by S101 is not stored), and wait for the control module to send a new current diagnostic code so as to re-enter S101.

[0073] This embodiment stores the current diagnostic code in the corresponding target cache queue, thereby ensuring that all detected fault information is completely recorded without omission. The diagnostic code stored in this embodiment can be used to trace the time, location, cause, etc. of the equipment failure, helping maintenance personnel to locate the problem more quickly and repair it.

[0074] This embodiment can display all the diagnostic codes in the cache queue on the interactive interface. Specifically, this embodiment can centrally display the diagnostic codes in all the cache queues on the interactive interface, so that the user can intuitively browse the fault information of each device component, which is convenient for quickly understanding the overall operating status of the equipment, so as to make timely and effective maintenance and management decisions. As a feasible implementation method, during the execution of this embodiment, the interactive module can continuously execute the diagnostic code display operations of S104~S108. As another feasible implementation method, the interactive module can cyclically execute the diagnostic code display operations of S104~S108 after storing the current diagnostic code in the target cache queue.

[0075] S104: Determine the queue display order of all the cache queues;

[0076] Among them, the queue display order refers to the display order between queues. After the diagnostic codes in the cache queues with a higher queue display order are displayed, the diagnostic codes in the cache queues with a lower queue display order are displayed. In this embodiment, the queue display order of all cache queues can be set in the configuration file. In this step, the queue display order of all the cache queues can be determined by reading the configuration file. Taking the cache queue including a prompt queue, an alarm queue and a fault queue as an example, the queue display order can be a fault queue, an alarm queue, and a prompt queue in sequence.

[0077] S105: selecting the cache queue as the current queue to be displayed according to the queue display order;

[0078] Among them, the current queue to be displayed is the cache queue that currently needs to be displayed. In this embodiment, the corresponding cache queue can be selected as the current queue to be displayed according to the queue display order, so that all diagnostic codes in the current queue to be displayed are displayed in sequence in the interactive interface.

[0079] S106: Determine whether the current queue to be displayed is empty; if so, proceed to S105; if not, proceed to S107;

[0080] If the current queue to be displayed does not store a diagnosis code, it means that the current queue to be displayed is empty, and S105 can be re-entered to select a new current queue to be displayed; if the current queue to be displayed has stored a diagnosis code, the relevant operations of S107~S108 can be performed.

[0081] S107: Determine the display order of the diagnostic codes in the current queue to be displayed;

[0082] The display order of the diagnostic codes refers to the display order within the current queue to be displayed. In this embodiment, the display order of the diagnostic codes can be determined according to the severity of the diagnostic codes, so that diagnostic codes with higher severity are displayed first. The severity of the diagnostic codes is the fault severity or fault level corresponding to the diagnostic codes.

[0083] In this embodiment, a severity level table of all diagnosis codes may be pre-set in the configuration file, and the display order of the diagnosis codes may be determined by querying the severity level table.

[0084] S108: displaying the diagnostic codes in the current queue to be displayed in sequence on the interactive interface according to the diagnostic code display order;

[0085] Among them, based on the obtained diagnosis code display order, this embodiment can display the diagnosis codes in the current queue to be displayed in sequence on the interactive interface in order from high to low severity.

[0086] During the execution of S108, it can be determined whether the diagnostic codes in the current queue to be displayed have been displayed; if they have been displayed, the operation of S105 is entered to select the cache queue as the current queue to be displayed according to the queue display order; if they have not been displayed, S108 is continued to be executed.

[0087] In the process of displaying the diagnostic code from S104 to S108, the display order of all cached queues is first determined, and then the queues are selected one by one for display in this order. For each queue to be displayed, this embodiment will first determine whether it is empty. If it is empty, the next queue will be selected; if it is not empty, the display order is determined according to the severity of the diagnostic code, and the diagnostic codes are displayed one by one in this order on the interactive interface. When all the diagnostic codes of a queue are displayed, the system will automatically select the next queue for display, ensuring that all fault information can be displayed to the user in an orderly and efficient manner.

[0088] The fault information management method provided in this embodiment is applied to the interactive module of the fault diagnosis system, and the fault diagnosis system also includes n acquisition modules and n control modules, and each of the acquisition modules is connected to the corresponding equipment components so as to transmit the collected working parameters to the control module. This embodiment integrates multiple acquisition modules to capture the working parameters of each equipment component in real time, and uses the control module to automatically generate diagnostic codes, and then combines the cache queue to achieve centralized management of fault information, ensuring that all detected fault information can be classified and stored without omission. This embodiment also centrally displays the diagnostic codes in all cache queues through an interactive interface. During the display process, the queue display order of all cache queues is first determined, and then the current queue to be displayed is selected one by one according to the queue display order for display. For each queue to be displayed, this embodiment will first determine whether it is empty. If it is empty, continue to select the next cache queue; if it is not empty, the diagnostic code display order is determined according to the severity of the diagnostic code, and the diagnostic code is displayed one by one on the interactive interface according to the diagnostic code display order. The above diagnostic code display process can ensure that all fault information can be displayed to the user in an orderly and efficient manner, so that the user can intuitively view the fault status of the device. Therefore, this embodiment can centrally manage and display the fault information of the equipment, thereby improving the safety of equipment operation.

[0089] As for Figure 1 Further introduction to the corresponding embodiment: before displaying the diagnostic codes in the current queue to be displayed in sequence on the interactive interface according to the diagnostic code display order, the total number of diagnostic codes stored in all the cache queues can also be determined; the diagnostic code display period of the interactive interface is queried, and the ratio of the diagnostic code display period to the total number of diagnostic codes is set as the single diagnostic code display time. The single diagnostic code display time refers to the display duration of a diagnostic code on the interactive interface. On the basis of determining the above-mentioned single diagnostic code display time, this embodiment can display the diagnostic codes in the current queue to be displayed in sequence on the interactive interface according to the diagnostic code display order and the single diagnostic code display time. After determining the total number of diagnostic codes stored in the cache queue, this embodiment can calculate the display time of each diagnostic code according to the diagnostic code display period of the interactive interface (such as 60 seconds), to ensure that all diagnostic codes can be fully displayed within the set period. The above method effectively balances the comprehensiveness of information and the fluency of display.

[0090] As for Figure 1Further introduction to the corresponding embodiment: before displaying the diagnostic codes in the current queue to be displayed in sequence on the interactive interface according to the diagnostic code display order, the diagnostic code display period of the interactive interface can also be queried; the time weight of each diagnostic code is set according to the severity of the diagnostic code; and the single diagnostic code display time of each diagnostic code is calculated according to the time weight under preset constraints; wherein the preset constraints are: the single diagnostic code display time is positively correlated with the time weight, and the sum of the single diagnostic code display times of all diagnostic codes is equal to the diagnostic code display period. The single diagnostic code display time refers to the display duration of a diagnostic code on the interactive interface. Based on the determination of the above-mentioned single diagnostic code display time, this embodiment can display the diagnostic codes in the current queue to be displayed in sequence on the interactive interface according to the diagnostic code display order and the single diagnostic code display time.

[0091] This embodiment queries the diagnosis code display cycle of the interactive interface, and then assigns a time weight to each diagnosis code according to the severity of the diagnosis code. Under the preset constraint conditions (i.e., the display time of a single diagnosis code is positively correlated with the time weight, and the sum of the single display time of all diagnosis codes is equal to the total display cycle), the specific time when each diagnosis code should be displayed is calculated to ensure that within the limited display cycle, diagnosis codes of different importance can be reasonably displayed.

[0092] As for Figure 1 In the further introduction of the corresponding embodiment, the above cache queue includes a prompt queue, an alarm queue and a fault queue; accordingly, the embodiment can determine the corresponding target cache queue from all cache queues in the following manner, including:

[0093] If the diagnostic code type of the current diagnostic code is a prompt diagnostic code, setting the prompt queue as a target cache queue corresponding to the current diagnostic code;

[0094] If the diagnostic code type of the current diagnostic code is an alarm type diagnostic code, setting the alarm queue as a target cache queue corresponding to the current diagnostic code;

[0095] If the diagnostic code type of the current diagnostic code is a fault type diagnostic code, the fault queue is set to a target cache queue corresponding to the current diagnostic code.

[0096] As for Figure 1Further introduction to the corresponding embodiment, after receiving the current diagnostic code sent by the control module, it also includes: judging whether the log information corresponding to the current diagnostic code is stored in the abnormal log; if not, storing the log information corresponding to the current diagnostic code in the abnormal log. In the above manner, it is possible to check whether there are relevant records of the current diagnostic code in the abnormal log. If not, the log information corresponding to the current diagnostic code will be generated and saved in the abnormal log for subsequent analysis and processing.

[0097] As for Figure 1 Further introduction to the corresponding embodiment, this embodiment can store the current diagnostic code to the target cache queue in the following manner: determine whether there is an idle storage unit in the target cache queue; if so, store the current diagnostic code to the idle storage unit; if not, delete the diagnostic code with the earliest storage time in the target cache queue, so as to store the current diagnostic code to the target cache queue. The above embodiment first determines whether there is an idle storage unit in the target cache queue. If there is an idle unit, it will store the current diagnostic code directly in the idle unit; if there is no idle unit, this embodiment will delete the diagnostic code with the earliest storage time in the target cache queue to free up space, and then store the current diagnostic code to the queue to ensure that the information in the queue remains up to date and valid.

[0098] The process described in the above embodiment is explained below through an embodiment in actual application.

[0099] Construction machinery and agricultural machinery are generally equipped with fault diagnosis systems. The control module in the fault diagnosis system diagnoses the fault point and sends the diagnostic code to the interactive module for display, so as to locate the fault of the whole machine and troubleshoot it efficiently. With the intelligent development of industry and agriculture, the integration of functions of large-scale construction machinery and agricultural machinery is increasing. The above-mentioned models often have multiple working parts, but because different working parts are scattered in various parts of the machine, each part needs to be centrally controlled. The control requirements of the whole machine are high, and it is difficult to diagnose and locate the fault. At the same time, the management and display of diagnostic information of multiple working parts competes for the display resources of the interactive module, which makes the diagnostic code easy to lose. When the driver operates the vehicle under the above circumstances, it causes damage to the vehicle.

[0100] In response to the technical problems existing in the above-mentioned related technologies, the present embodiment provides a fault diagnosis method and a distributed centralized control system, and proposes a fault diagnosis scheme for multiple working mechanisms of construction machinery and agricultural machinery. The scheme includes a multi-control module diagnostic coding, transmission and display method. Through the implementation of this technical scheme, efficient centralized management, transmission and display of diagnostic information of each working component in the distributed centralized control system is achieved, ensuring the efficient coordinated operation of multiple working components of large-scale construction machinery and agricultural machinery, improving diagnostic efficiency and the working efficiency of the entire machine, and improving the operating experience.

[0101] See also Figure 3 , Figure 3 A schematic diagram of a fault diagnosis method and a distributed centralized control system provided in an embodiment of the present application, wherein the centralized control system includes a CAN bus, an interaction module, acquisition modules 1 to n, and control modules 1 to n. The control module includes a diagnostic code encoding rule and a diagnostic code transmission control module, and the diagnostic code transmission control module includes a data frame encoding rule and a diagnostic code transmission rule. The interaction module includes a diagnostic control module.

[0102] The acquisition module and the control module are electrically connected and are responsible for acquiring the sensor status of the corresponding working parts; the control module and the interaction module are electrically connected using a CAN (Controller Area Network) bus and are responsible for the acquisition and logical judgment of sensor data, the generation of diagnostic codes and the transmission of diagnostic codes.

[0103] The CAN bus is electrically connected to the control module and the interactive module, and serves as a network carrier for data transmission of the entire vehicle; the interactive module is electrically connected to each control module using the CAN bus, and is responsible for the aggregation, control, and display of diagnostic information. In this solution, the control module collects the working parameters of the corresponding working components through the acquisition module, and analyzes the working parameters to see if an abnormality occurs. When an abnormality is detected, the corresponding abnormality is encoded according to the diagnostic code encoding rules, and the code is sent to the interactive module through the diagnostic code transmission control module. The interactive module includes a diagnostic control module, and the diagnostic control module performs relevant logical processing on the diagnostic code received from the control module, and rolls back and displays the diagnostic code according to the priority and sequence of the diagnostic code, and sends corresponding prompt information to the driver. Furthermore, when there are multiple control modules in the distributed centralized control system, the diagnostic control module centrally manages the diagnostic information, rolls back and displays the diagnostic code according to the priority and sequence of the diagnostic code, and sends corresponding prompt information to the driver.

[0104] See also Figure 4 , Figure 4A schematic diagram of a diagnostic code encoding rule provided in an embodiment of the present application, the diagnostic code can be 32-bit binary data (bit0~bit31), including a component code (8 bits), a sensor code (11 bits), a diagnostic type (5 bits), a reserved bit (1 bit) and the number of occurrences of the diagnostic code (7 bits). When transmitted, the low bit of the diagnostic code is placed at a low address. The above bit represents a bit, and the diagnostic type is the diagnostic code type. The above bit represents a bit.

[0105] The above-mentioned component code is used to mark and retrieve the corresponding working component;

[0106] The sensor code is used to mark and retrieve the sensor in the working part;

[0107] The above diagnosis type is used to mark and retrieve the diagnosis level and severity mark of the diagnosis type. In this technical solution, it includes but is not limited to three different diagnosis levels: prompt, warning, and fault. The analysis of the diagnosis type is as follows:

[0108] The diagnostic type includes a 5-bit field. The first and second bit fields are used to indicate the fault level, such as 00 for fault, 01 for alarm, 10 for prompt, and 11 for reserved. The third, fourth, and fifth bit fields are identifiers of the severity of the diagnostic code, with a value range of 000~111, with decreasing severity.

[0109] The reserved bits are used to synchronize with international standards, ensuring that the encoding in this technical solution is synchronized with the international encoding format.

[0110] The number of occurrences of this diagnostic code is used to mark the cumulative number of occurrences of this diagnostic code since the machine was powered on.

[0111] The diagnostic code transmission control module includes the diagnostic code data frame coding rules and diagnostic code transmission rules. The diagnostic code coding rules refer to the compilation rules of the diagnostic code. For example, a diagnostic code is: x025458414. The diagnostic code data frame coding rules are the transmission arrangement rules when multiple diagnostic codes are transmitted on the bus.

[0112] The data frame encoding rules of the diagnosis code include a single diagnosis code data frame encoding rule and a multi-diagnosis code data frame encoding rule.

[0113] The single diagnostic code data frame encoding rules include the single diagnostic code data frame format and the specified CAN ID (identifier), such as CAN ID 1, see Figure 5 , Figure 5 A schematic diagram of a data frame encoding rule for a single diagnostic code provided in an embodiment of the present application, including fields for other states and fields corresponding to diagnostic code information.

[0114] The multi-diagnostic code data frame encoding rule includes a multi-diagnostic code status data frame and a multi-diagnostic code data frame 1~m; the multi-diagnostic code status data frame has its corresponding CAN ID (such as CAN ID 2), and the multi-diagnostic code data frame 1~m has its corresponding CAN ID (such as CAN ID 3).

[0116] The diagnosis control module includes cache queue control strategy and display control strategy.

[0117] See also Figure 7 , Figure 7 A schematic diagram of a cache queue control strategy provided in an embodiment of the present application, the implementation process of which is as follows:

[0118] After power-on, the diagnostic code is scanned. If a diagnostic code exists, the diagnostic code type (such as prompt diagnostic code, alarm diagnostic code, fault diagnostic code, and reserved diagnostic code) is determined.

[0119] If the diagnostic code is a prompt diagnostic code, it is determined whether the diagnostic code is a new prompt by comparing the prompt queue; if so, the log is updated, the prompt queue is updated and a sorting operation is performed; if not, the operation of scanning the diagnostic code is entered.

[0120] If the diagnostic code is an alarm diagnostic code, the alarm queue is compared to determine whether the diagnostic code is a new alarm; if so, the log is updated, the alarm queue is updated and a sorting operation is performed; if not, the diagnostic code scanning operation is performed.

[0121] If the diagnostic code is a fault type diagnostic code, it is determined whether the diagnostic code is a new fault by comparing it with the fault queue; if so, the log is updated, the fault queue is updated and a sorting operation is performed; if not, the operation of scanning the diagnostic code is entered.

[0122] If the diagnostic code is a reserved diagnostic code, it will not be processed and the operation of scanning diagnostic codes will be entered.

[0123] See also Figure 8 , Figure 8 A flow chart of a display control strategy provided in an embodiment of the present application, the implementation process of which is as follows:

[0124] After power-on, scan the diagnostic queue to determine whether there is a fault diagnostic code in the scanned diagnostic queue; if so, execute the display control strategy.

[0125] If there is no fault diagnostic code in the scanned diagnostic queue, the alarm queue is scanned to determine whether there is an alarm diagnostic code in the alarm queue; if so, the display control strategy is executed.

[0126] If there is no alarm diagnostic code in the scanned diagnostic queue, the prompt queue is scanned to determine whether there is a prompt diagnostic code in the prompt queue; if so, the display control strategy is executed; if not, the operation of scanning the diagnostic queue is entered.

[0127] See also Fig. 9 , Fig. 9 A schematic diagram of a cache queue provided in an embodiment of the present application; the cache queue may contain storage units 1 to p. The cache queue control strategy provides a cache queue, an operation method of the cache queue, and a log;

[0128] The cache queue includes a plurality of storage units, each of which can store a diagnostic code, and is used for temporarily storing and processing a scanned new diagnostic code.

[0129] The cache queue operation method includes but is not limited to operations such as queueing, dequeuing, and sorting; when executing the queueing operation, when the diagnostic control module detects that there is a diagnostic code on the bus, the diagnostic code is compared one by one with the diagnostic code stored in the storage unit. If it is a new diagnostic code, the content of the storage unit in the cache queue is logically shifted right by one diagnostic code, and the new diagnostic code is stored in storage unit 1. In the logical right shift operation, if the cache queue is full, the last cache unit is dequeued. If the cache queue is updated, a sort is performed, and the sorting is based on the severity level of the diagnostic code, and the most severe one is arranged in storage unit 1 of the cache queue. If a duplicate diagnostic code is detected, no processing is performed, and the result is that it is discarded.

[0130] The log is a local storage file used to store newly triggered diagnostic codes locally for subsequent record keeping and review.

[0131] The display control strategy includes a priority control method, which can determine the priority display order according to the diagnosis level. The lower the diagnosis level code, the higher the display priority. The display control strategy includes a rollback display mechanism. For example, when the cache queue contains multiple diagnostic codes, the rollback display can be performed according to the priority control strategy. The rollback display mechanism also includes a timing mechanism. When a single diagnostic code exists, the display time is t. When there are two diagnostic codes to roll back, the display time of each diagnostic code is t1, and so on. When there are n diagnostic codes to roll back, the display time of each diagnostic code is tn, then t>t1> t2>…>tn, and the value of the above display time t depends on the display effect.

[0132] This embodiment proposes a fault diagnosis scheme for multiple working mechanisms of construction machinery and agricultural machinery, which includes a multi-control module diagnostic coding, transmission and display method. Through the implementation of this technical scheme, efficient centralized management, transmission and display of diagnostic information of each working component in a distributed centralized control system is achieved, ensuring the efficient coordinated operation of multiple working components of large-scale construction machinery and agricultural machinery, improving diagnostic efficiency and the working efficiency of the entire machine, and enhancing the operating experience.
