Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of engineering machinery, and in particular to a control system and method for presenting fault information and uploading historical records, and in particular to a control system and method for presenting fault information and uploading historical records of an excavator. Background Art
[0002] Fault diagnosis cycle: The vehicle controller unit (VCU) detects the vehicle status at regular intervals or other control modules transmit fault information to the vehicle controller (VCU) at regular intervals. This period of time is called the fault diagnosis cycle.
[0003] At present, fault alarms are processed by setting a time delay or real-time alarms. For example, excavator fault alarms include engine alarms and whole machine fault alarms. There are many fault alarm conditions, and the whole vehicle status is complex. There are occasional alarms when the fault alarm conditions are not suitable for the actual working conditions, intermittent fault alarms cannot be presented, and instrument alarms flash. At the same time, due to the storage limitations of the remote management platform of the remote equipment terminal, the upload cycle of the whole vehicle fault record data is long and the upload frequency is low (generally, the frequency of uploading fault information to GPS is once every few minutes, but the fault information is generated once every few milliseconds. The conventional practice is to upload the fault information that occurs at the current moment. If the fault occurs intermittently and happens to occur within the upload interval, the fault information cannot be uploaded.), which cannot meet the problem of high-frequency fault alarm data recording and cannot accurately record intermittent fault alarm information. Summary of the invention
[0004] In view of the deficiencies of the prior art, the present invention provides a control system and method for presenting fault information and uploading historical records, which can achieve accurate transmission of fault information and the start and end times of the fault duration.
[0005] To achieve the above object, the present invention provides the following technical solutions:
[0006] In the first aspect, the present invention proposes a control system for presenting fault information and uploading historical records, including a vehicle controller, an instrument, a remote device terminal and a remote device management platform; the vehicle controller is communicatively connected to the instrument and the remote device terminal, and the remote device terminal is communicatively connected to the remote device management platform; the vehicle controller is used to obtain fault information, and transmit the fault information to the instrument, and then present the fault information to the driver through the instrument, and at the same time, transmit the fault information to the remote device terminal, and the remote device terminal transmits the received fault information to the remote device management platform; the fault information includes the time when each fault occurs and the duration of the fault.
[0007] In combination with the first aspect, further, the control system of the present invention also includes a component control module, and the vehicle controller is communicatively connected with the component control module; the fault information includes vehicle fault information generated by the vehicle controller and component fault information generated by the component control module; the component control module is used to generate component fault information based on data collected by the sensor, and transmit the generated component fault information to the vehicle controller.
[0008] In combination with the first aspect, further, the method for the vehicle controller to obtain fault information is: the vehicle controller generates vehicle fault information based on data collected by sensors and receives component fault information from a component control module.
[0009] In combination with the first aspect, further, the component control module refers to other control modules (such as engine controller ECU, etc.) except the vehicle control unit (VCU).
[0010] Combined with the first aspect, further, usually when the power-off demand occurs in the gap between two fault information uploads, the power-off information will not be able to be uploaded to the remote device management platform. In order to solve this problem, the control system of the present invention also includes an electric lock and a power relay, and the vehicle controller is electrically connected to the electric lock; when the electric lock sends a power-off signal to the vehicle controller. The vehicle controller is electrically connected to the power relay; when the vehicle controller receives the power-off signal, it delays the power-off signal and sends it to the power relay; after receiving the power-off signal, the power relay performs a delayed power-off of the whole machine, so that the vehicle controller can upload the fault information to the remote device management platform.
[0011] In a second aspect, further, the present invention proposes a control method for presenting fault information and uploading historical records, comprising the following steps:
[0012] The vehicle controller obtains fault information and records the number of fault diagnosis cycles from the time the fault occurs to the current moment;
[0013] The vehicle controller detects that the fault occurs again and records the number of fault diagnosis cycles from the time when the fault occurs again to the current time;
[0014] Calculate the difference between the fault diagnosis cycle numbers of two fault occurrence records to determine whether the difference is less than a preset threshold;
[0015] If the difference is less than or equal to the threshold, the fault is considered to be a continuous fault, and the number of fault diagnosis cycles from the first occurrence of the fault to the current moment and the number of fault diagnosis cycles during which the fault continues are recorded;
[0016] If the difference is greater than the threshold, the fault is considered to be an intermittent fault, and the number of fault diagnosis cycles from the occurrence of the fault to the current moment is recorded;
[0017] When the fault is determined to be a continuous fault, the fault diagnosis cycle number of the continuous fault is compared with the preset fault diagnosis cycle number threshold. If the fault diagnosis cycle number of the continuous fault is greater than or equal to the fault diagnosis cycle number threshold, the fault will be displayed on the instrument and a fault alarm will be issued; if the fault diagnosis cycle number of the continuous fault is less than the fault diagnosis cycle number threshold, the fault will not be sent to the instrument for display;
[0018] After receiving the identification uploaded by the remote device terminal or receiving the power-off signal, the vehicle controller sends the fault information to the remote device management platform through the remote device terminal. After the fault information is sent to the remote device management platform, the vehicle controller clears the record of the fault information and restarts the count;
[0019] The remote equipment management platform directly obtains the fault occurrence time and the duration information of the continuous fault according to the received fault information and the current time.
[0020] In combination with the second aspect, further, the fault includes a continuous fault and an intermittent fault; if it is a continuous fault, the fault information includes the number of fault diagnosis cycles from the first occurrence of the continuous fault to the current moment and the number of fault diagnosis cycles of the continuous fault; if it is an intermittent fault, the fault information includes recording the number of fault diagnosis cycles from the occurrence of the intermittent fault to the current moment.

[0022] Compared with the prior art, the present invention provides a control system and method for presenting fault information of an excavator and uploading historical records, which has the following beneficial effects:
[0023] In view of the fact that occasional alarms occur due to fault alarm conditions not being suitable for actual working conditions, intermittent alarms cannot be presented, and instrument alarms flash, the control system and method of the present invention can accurately transmit fault information and the start and end times of the fault under the condition of long-term uploading to the remote management platform without the need for excessive message data, ultimately achieving accurate recording of the fault history on the remote management platform.

[0029] Example 1
[0030] like Figure 1As shown, the present invention proposes a control system for presenting fault information and uploading historical records, including a vehicle controller, a component control module, an instrument, an electric lock, a power relay, a remote device terminal and a remote device management platform; the vehicle controller is respectively connected to the component control module, the instrument and the remote device terminal through CAN communication, and the remote device terminal is connected to the remote device management platform through a GPRS signal; the fault information includes vehicle fault information generated by the vehicle and component fault information generated by the component control module; the vehicle controller is respectively electrically connected to the electric lock and the power relay; the vehicle controller is used to generate vehicle fault information according to data collected by the sensor, and transmit the generated vehicle fault information to the instrument, and then present the vehicle fault information to the driver through the instrument, and at the same time, transmit the generated vehicle fault information to the remote device terminal, and the remote device terminal transmits the received vehicle fault information to the remote device management platform; the component control module is used to generate component fault information according to data collected by the sensor, and transmit the generated component fault information to the vehicle controller, and the vehicle controller also transmits the received component fault information to the instrument and the remote device terminal respectively.
[0031] In a specific implementation of this embodiment, the component control module refers to other control modules (such as an engine controller ECU, etc.) except the vehicle control unit (VCU).
[0032] like Figure 2 As shown, the present invention proposes a control method for presenting fault information and uploading historical records, and the specific steps are as follows:
[0033] When the remote device terminal transmits the fault information to the remote device management platform, it uploads the identifier to the vehicle controller to record the transmission time of the remote device terminal transmitting the fault information to the remote device management platform. After generating the vehicle fault information or receiving the component fault information, the vehicle controller counts the number of fault diagnosis cycles from the occurrence of the fault to the current moment; when the fault occurs again, it also records the number of fault diagnosis cycles experienced by the new fault to the current moment, and calculates the difference between the fault diagnosis cycles recorded for the two faults. The difference represents the number of fault cycles between the two faults. A threshold is set. When the difference is less than the threshold, the control system considers the fault to be a continuous fault, otherwise it is an intermittent fault; when the fault is determined to be a continuous fault, the number of fault diagnosis cycles from the first occurrence of the continuous fault to the current moment and the number of fault diagnosis cycles of the continuous fault are recorded; when the fault is determined to be an intermittent fault, the number of fault diagnosis cycles from the occurrence of the intermittent fault to the current moment is recorded. After receiving the identifier uploaded by the remote device terminal, the vehicle controller sends the above information corresponding to the continuous fault and the intermittent fault to the remote device terminal, and then clears the record and records it again, so that the time of the fault occurrence can be accurately determined.
[0034] When the excavator loses power, the vehicle controller receives the power-off signal, controls the power relay to delay disconnection to achieve delayed power-off of the vehicle controller, and sends the fault record information and the vehicle power-off signal to the remote device terminal. After receiving the fault record information and the vehicle power-off signal, the remote device terminal immediately uploads the fault information to the remote device management platform. The remote device management platform determines the time of continuous fault occurrence and the time of first fault occurrence through the above-mentioned fault information received and the current time; the remote device management platform determines the time of intermittent fault occurrence based on the fault diagnosis cycle count and the current time.
[0035] When the fault is determined to be a continuous fault, the number of fault diagnosis cycles of the continuous fault is determined; when the number of fault diagnosis cycles of the continuous fault exceeds a threshold, the fault information is sent to the instrument for display.
[0036] When a fault occurs, the fault is counted according to the number of fault diagnosis cycles, and the remote device terminal uploads it to the remote device management platform and sends an identification to the vehicle control unit (VCU). The fault is counted according to the number of fault diagnosis cycles and then cleared to zero after being sent to the remote management platform. This method can accurately determine the time when the fault occurs.
[0037] After a fault occurs, the vehicle controller detects the fault again and determines whether the fault continues to occur by comparing the fault diagnosis cycle count. If it is a continuous fault, the duration is recorded and transmitted to the remote device terminal. It is not necessary to transmit the fault time of each fault diagnosis cycle, thereby reducing the frequency of message sending and lowering the communication load rate.
[0038] For the current fault, the number of fault diagnosis cycles in the continuous state is compared with the preset threshold to determine whether to send a fault alarm to the instrument, and the alarm status is more accurate.
[0039] It should be noted that, in this application, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or equipment. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or equipment including the elements.
[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
