Description

{System for Failure Diagnosis of Agricultural Vehicle}

The present invention relates to agricultural work vehicles, and more specifically, to fault diagnosis of agricultural work vehicles.

Agricultural work vehicles are used to cultivate crops necessary for human life by utilizing the land. For example, combines and tractors are agricultural work vehicles. A combine is a vehicle that performs the work of harvesting and threshing crops such as rice, barley, wheat, and soybeans. A tractor is a vehicle that performs agricultural work while moving or stationary by connecting various types of work machines. The work machine is connected to a hitch mounted on the tractor, and the hitch is raised by a hydraulic device to lift the work machine off the ground and perform agricultural work.

In the case of these agricultural work vehicles, they are usually exposed to harsher and more aggressive environments than regular passenger cars, so they are easily exposed to breakdowns due to environmental conditions or physical external forces.

In particular, since agricultural work vehicles generally perform agricultural work using the driving force of the engine, the condition of the agricultural work vehicle may deteriorate further when performing agricultural work, which may increase the risk of breakdown. Therefore, agricultural work vehicles require periodic inspection. To this end, agricultural work vehicles are generally inspected at maintenance centers by experts using their experience or diagnostic equipment. However, since agricultural work vehicles are special equipment, there are not many maintenance centers that have experts who handle agricultural work vehicles. In addition, agricultural work vehicles are large and slow, making it difficult to move them to maintenance centers.

The present invention is intended to solve the above-described problems, and its technical feature is to provide a fault diagnosis system for an agricultural work vehicle capable of predicting a fault in the agricultural work vehicle using a fault diagnosis module.

In addition, the present invention has as its technical feature a system for diagnosing a breakdown of an agricultural work vehicle that can remotely diagnose a breakdown of an agricultural work vehicle.

In addition, the present invention has as its technical feature a system for diagnosing faults in agricultural work vehicles, which can diagnose faults by comparing an agricultural work vehicle that is a target of fault diagnosis with another agricultural work vehicle.

According to one aspect of the present invention for achieving the above-described purpose, a system for diagnosing a fault in an agricultural work vehicle comprises: a data collection device that collects data generated in a first agricultural work vehicle when the first agricultural work vehicle is set to an initial condition in which the first agricultural work vehicle is in a predetermined state; a database that stores data generated in the first agricultural work vehicle; and a fault diagnosis module that determines whether the first agricultural work vehicle is faulty using the data collected by the data collection device.

According to the present invention, since it is possible to predict a breakdown of an agricultural work vehicle using a breakdown diagnosis module, not only can a response to a breakdown of an agricultural work vehicle be made quickly, but also a breakdown of an agricultural work vehicle can be prevented in advance, thereby reducing economic losses.

In addition, since according to the present invention, a breakdown of an agricultural work vehicle can be diagnosed remotely, there is an effect of being able to diagnose a breakdown of an agricultural work vehicle more conveniently.

In addition, according to the present invention, a fault can be diagnosed by comparing an agricultural work vehicle that is the subject of fault diagnosis with another agricultural work vehicle, so there is an effect of increasing the accuracy of fault diagnosis.

Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

FIG. 1 is a drawing showing a fault diagnosis system (hereinafter referred to as “fault diagnosis system”) for an agricultural work vehicle according to one embodiment of the present invention and a first agricultural work vehicle. As shown in FIG. 1, the fault diagnosis system (100) diagnoses a fault in the first agricultural work vehicle (10). The fault diagnosis system (100) collects data generated in the first agricultural work vehicle (10) and determines whether the first agricultural work vehicle (10) is faulty using the collected data.

In one embodiment, the fault diagnosis system (100) can collect data generated from the first agricultural work vehicle (10) through terminal communication or wireless communication with the first agricultural work vehicle (10).

Referring to FIG. 2 below, the fault diagnosis system (100) will be described in more detail.

FIG. 2 is a block diagram showing the configuration of a fault diagnosis system (100) according to one embodiment of the present invention. As shown in FIG. 2, the fault diagnosis system (100) includes a data collection device (210), a database (220), and a fault diagnosis module (230), and may further include an HMI (Human Machine Interface) and a diagnostic switch (250).

The data collection device (210) collects data from the first agricultural work vehicle (10). Specifically, the data collection device (210) collects data from at least one of the ECU (Engine Control Unit), the TCU (Transmission Control Unit), and the HCU (Hydraulic Control Unit) of the first agricultural work vehicle (10). The data may include the amount of intake air supplied to the engine, the amount of fuel injected, the temperature of the fuel, the temperature of the engine oil, the pressure of the engine oil, the temperature of the TM (Transmission) oil, the temperature of the coolant, and the temperature of the hydraulic oil.

At this time, the ECU is a control device that controls the engine of the first agricultural work vehicle (10). The data collection device (210) can collect the intake amount supplied to the engine from the ECU, the fuel injection amount, the fuel temperature, the engine oil temperature, the engine oil pressure, and the coolant temperature.

The TCU is a control device that controls the transmission of the first agricultural work vehicle (10). The data collection device (210) can collect the temperature of TM oil, etc. from the TCU.

The HCU is a control device that controls the hydraulic pressure of the first agricultural work vehicle (10). The data collection device (210) can collect the temperature of the hydraulic oil, etc. from the HCU.

The data collection device (210) collects data from the first agricultural work vehicle (10) when the first agricultural work vehicle (10) is set as an initial condition in which the first agricultural work vehicle (10) is in a predetermined state. For example, when the first agricultural work vehicle (10) is set as an initial condition, the first agricultural work vehicle (10) may be in a stopped state, or the first agricultural work vehicle (10) may be in a state in which it performs a certain operation in a certain space. Accordingly, the data collection device (210) may collect data from the first agricultural work vehicle (10) in a stopped state, or may collect data from the first agricultural work vehicle (10) when the first agricultural work vehicle (10) is in a state in which it performs a certain operation in a certain space.

At this time, the initial conditions may be the same each time data is collected from the first agricultural work vehicle (10) by the data collection device (210). The initial conditions may include engine RPM (Revolutions Per Minute), gear settings, etc.

The reason why the data collection device (210) according to the present invention collects data from the first agricultural work vehicle (10) when the first agricultural work vehicle (10) is set to an initial condition in which the first agricultural work vehicle (10) is in a predetermined state is that the values of the data collected by the data collection device (210) may be different if the state of the first agricultural work vehicle (10) is different each time the data collection device (210) collects data, so that the reliability of the collected data is improved by the data collection device (210) collecting data when the state of the first agricultural work vehicle (10) is under the same condition.

In one embodiment, the data collection device (210) can collect data of the first agricultural work vehicle (10) according to a predetermined cycle. For example, the data collection device (210) can collect data generated from the first agricultural work vehicle (10) at one-week intervals.

In another embodiment, the data collection device (210) can collect data of the first agricultural work vehicle (10) at regular intervals for a predetermined period of time. For example, the data collection device (210) can collect data generated from the first agricultural work vehicle (10) for a week on an hourly basis.

The data collection device (210) collects data generated from the first agricultural work vehicle (10) and stores it in a database (220).

The fault diagnosis module (230) determines whether the first agricultural work vehicle is faulty using data stored in the database (220) by the data collection device (210). In one embodiment, the fault diagnosis module (230) can determine whether the first agricultural work vehicle is faulty using data collected by the data collection device (210) according to a predetermined cycle. Specifically, the fault diagnosis module (230) can arrange the values of the data collected according to the predetermined cycle on a time axis, and determine that a fault has occurred in the first agricultural work vehicle (10) if the slope of the data values with respect to the time axis is greater than or less than 0. In this way, the fault diagnosis module (230) can determine that a fault has occurred in the first agricultural work vehicle (10) if the values of the data collected according to the predetermined cycle show an increasing or decreasing trend.

Furthermore, the fault diagnosis module (230) can arrange the values of data collected according to a predetermined cycle on a time axis, and if the slope of the data values for the time axis deviates from the first reference section, it can be determined that an abnormality has occurred in the first agricultural work vehicle (10). At this time, the first reference section can be set to a minimum value and a maximum value.

For example, if the minimum value of the first reference interval is set to -1 and the maximum value of the first reference interval is set to +1, the fault diagnosis module (230) can determine that a problem has occurred in the first agricultural work vehicle (10) if the slope of the data value with respect to the time axis is outside the range of -1 to +1. Accordingly, the fault diagnosis module (230) can determine that a problem has occurred in the first agricultural work vehicle (10) if the value of the collected data shows a rapid increase or decrease trend.

In another embodiment, the fault diagnosis module (230) can determine whether the first agricultural work vehicle (10) is faulty using data collected at regular intervals for a predetermined period by the data collection device (210). Specifically, the fault diagnosis module (230) calculates an average value of data collected at regular intervals for a predetermined period. The fault diagnosis module (230) can determine that a problem has occurred in the first agricultural work vehicle (10) if the value of the data currently collected by the data collection device (210) is larger or smaller than the calculated average value.

Furthermore, the fault diagnosis module (230) can determine that a problem has occurred in the first agricultural work vehicle (10) if the absolute value of the deviation between the calculated average value and the data value currently collected by the data collection device (210) is greater than a predetermined reference value. When following this embodiment, the fault diagnosis module (230) can compensate for a variable when calculating the average value, and the variable can mean the outside temperature, etc.

The fault diagnosis module (230) can determine whether there is a fault in the first agricultural work vehicle (10) and transmit the determination result to the HMI (240).

The HMI (240) can receive the judgment result from the fault diagnosis module (230) and output it to the user. In addition, the HMI (240) can output the procedure for fault diagnosis and the initial conditions of the first agricultural work vehicle (10) to the user. At this time, when the initial conditions of the first agricultural work vehicle (10) are set, the HMI (240) can output to the user that the setting of the initial conditions is complete.

The diagnostic switch (250) initially sets the first agricultural work vehicle (10) as the initial condition, and when resetting, the first agricultural work vehicle (10) can be set in batches with the initial condition. Specifically, when the first agricultural work vehicle (10) is initially set as the initial condition by the user, the diagnostic switch (250) can be set in batches with the initially set initial condition when the first agricultural work vehicle (10) is reset to the initial condition to collect data from the data collection device (10). At this time, there can be a plurality of initial conditions.

For example, when the initial conditions are gear neutral and engine RPM is 1000 rpm, and the user initially sets the first agricultural work vehicle (10) to gear neutral and engine RPM to 1000 rpm, the diagnostic switch (250) can be set to reset the first agricultural work vehicle (10) to gear neutral and engine RPM to 1000 rpm.

In the above-described embodiment, the fault diagnosis system (100) was described as diagnosing a fault in the first agricultural work vehicle using the fault diagnosis module (230). However, in a modified embodiment, the fault diagnosis system (100) can perform a fault diagnosis remotely using a remote control system.

Hereinafter, the modified embodiment described above will be described in more detail with reference to FIG. 3. Meanwhile, the description of the configuration described in the above-described embodiment will be omitted, and only the configuration with an additional function among the existing configurations will be additionally described.

FIG. 3 is a block diagram showing the configuration of a fault diagnosis system using a remote control system according to a modified embodiment of the present invention.

As illustrated in FIG. 3, the fault diagnosis system (100) may further include a first communication module (260).

The fault diagnosis module (230) transmits data generated from the first agricultural work vehicle (10) by the data collection device (210), location information of the first agricultural work vehicle, and the result of determining whether the first agricultural work vehicle is faulty to the remote control system (300) through the first communication module (260).

The first communication module (260) transmits data, location information, and judgment results received from the fault diagnosis module (220) to the remote control system (300), and transmits information received from the remote control system (300) to the fault diagnosis module (230). In one embodiment, the first communication module (260) can communicate wirelessly with the remote control system (300).

The remote control system (300) remotely diagnoses whether the first agricultural work vehicle (10) is in a fault using data received from the fault diagnosis system (100). To this end, as shown in Fig. 3, the remote control system (300) includes a second communication module (320) and a remote control server (330).

The second communication module (320) transmits data, location information, and judgment results received from the first communication module (260) to the remote control server (330), and transmits information transmitted from the remote control server (330) to the first communication module (260). In one embodiment, the second communication module (320) can communicate wirelessly with the first communication module (260).

The second communication module (320) can collect data generated from the second agricultural work vehicle (10) from the second fault diagnosis system (335). The second communication module (320) can transmit data generated from the second agricultural work vehicle (340) to the remote control server (330). In one embodiment, the second communication module (320) can communicate wirelessly with the second fault diagnosis system (335). At this time, the second agricultural work vehicle (340) can be the same type of vehicle as the first agricultural work vehicle (10).

The remote control server (330) remotely diagnoses whether the first agricultural work vehicle (10) is broken using data received from the second communication module (320). Specifically, the remote control server (330) can remotely determine whether the first agricultural work vehicle (10) is broken by comparing data generated from the first agricultural work vehicle (10) with data generated from the second agricultural work vehicle (340).

In a modified embodiment, the remote control server (330) may receive location information of the first agricultural work vehicle (10) from the second communication module (320) and detect one or more second agricultural work vehicles (340) located within a first reference radius defined in advance based on the location information. At this time, the first reference radius may be an area where the outside temperature is the same as the location of the first agricultural work vehicle (10). In addition, the first reference radius may be an area within a specific distance based on the location of the first agricultural work vehicle (10). In addition, the first reference radius may be an area within a specific distance based on the location of the first agricultural work vehicle (10) and where the outside temperature is the same as the location of the first agricultural work vehicle (10).

The remote control server (330) receives data of one or more second agricultural work vehicles (340) from the second communication module (320), and the remote control server (330) compares data of one or more second agricultural work vehicles (340) with data of the first agricultural work vehicle (10) to remotely diagnose whether the first agricultural work vehicle (10) is broken.

According to this modified embodiment, the remote control server (330) may calculate an average value of data of one or more second agricultural work vehicles (340), and if the data value of the first agricultural work vehicle (10) is greater or less than the calculated average value, it may determine that an abnormality has occurred in the first agricultural work vehicle (10). Furthermore, the remote control server (330) may determine that an abnormality has occurred in the first agricultural work vehicle (10) if the absolute value of the deviation between the average value of data of one or more second agricultural work vehicles (340) and the data value of the first agricultural work vehicle (10) is greater than a predetermined reference value.

At this time, the data of the second agricultural work vehicle (340) may be data collected at regular intervals for a predetermined period by the second fault diagnosis system (335), and may be data collected from one or more second agricultural work vehicles (340) at the current point in time. Here, the current point in time may mean the same point in time as the point in time at which the data of the first agricultural work vehicle (10) was collected.

In another modified embodiment, the remote control server (330) may receive location information of the first agricultural work vehicle (10) from the second communication module (320) and detect one or more second agricultural work vehicles (340) located outside the first reference radius centered on the location information. For example, the remote control server may receive location information of the first agricultural work vehicle (10) and detect one or more second agricultural work vehicles (340) located outside the first reference radius centered on the location information but working in an area having soil similar to the soil on which the first agricultural work vehicle (10) works.

To this end, soil measurement units (not shown) may be formed in the first agricultural work vehicle (10) and the second agricultural work vehicle (340). The data collection device (210) may receive soil information of the soil being worked on from the soil measurement unit of the first agricultural work vehicle (10). The soil information received from the soil measurement unit of the first agricultural work vehicle (10) may be transmitted to the fault diagnosis module (230) via the database (220). The soil information of the first agricultural work vehicle (10) received by the fault diagnosis module (230) may be transmitted to the second communication module (320) by the first communication module (250), and the remote control server (330) may receive the soil information of the first agricultural work vehicle (10) from the second communication module (320). In addition, the remote control server (330) can receive soil quality information of the soil where one or more second agricultural work vehicles (340) work from the second fault diagnosis system (335). At this time, the outside temperature outside the first reference radius may be different from the location where the first agricultural work vehicle (10) is located. The remote control server (330) receives data of one or more second agricultural work vehicles (340), and the remote control server (330) can remotely diagnose whether the first agricultural work vehicle (10) is broken by comparing data of one or more second agricultural work vehicles (340) with data of the first agricultural work vehicle (10).

According to these other modified embodiments, the remote control server (330) calculates an average value of data of one or more second agricultural work vehicles (340), and if the data value of the first agricultural work vehicle (10) is larger or smaller than the average value of data of one or more second agricultural work vehicles (340), it can be determined that an abnormality has occurred in the first agricultural work vehicle (10). Furthermore, the remote control server (330) can be determined that an abnormality has occurred in the first agricultural work vehicle (10) if the absolute value of the deviation between the average value of data of one or more second agricultural work vehicles (340) and the data value of the first agricultural work vehicle (10) is larger than a predetermined reference value.

At this time, the data of one or more second agricultural work vehicles (340) may be data collected at regular intervals for a predetermined period by the second fault diagnosis system (335), and may be data collected from one or more second agricultural work vehicles (340) at the current point in time. Here, the current point in time may mean the same point in time as the point in time at which the data of the first agricultural work vehicle (10) was collected.

Meanwhile, in a modified embodiment, the remote control server (330) may perform a fault diagnosis of the first agricultural work vehicle (10) according to the judgment result of the fault diagnosis module (230). Specifically, if the remote control server (330) determines that an abnormality has occurred in the first agricultural work vehicle (10) by the fault diagnosis module (230), the remote control server (330) may not perform a fault diagnosis of the first agricultural work vehicle (10). In contrast, if the first agricultural work vehicle (10) is determined to be normal by the fault diagnosis module (230), the remote control server (330) may perform a fault diagnosis of the first agricultural work vehicle (10). The remote control server (330) performs a fault diagnosis when the first agricultural work vehicle (10) is determined to be normal, and transmits the fault occurrence determination result to the fault diagnosis module (230) when the first agricultural work vehicle (10) is determined to be abnormal, and transmits the normal determination result to the fault diagnosis module (230) when the first agricultural work vehicle (10) is determined to be normal.

The reason why the remote control server (330) according to the present invention does not perform a fault diagnosis on the first agricultural work vehicle (10) when the fault diagnosis module (230) determines that the first agricultural work vehicle (10) is abnormal, and performs a fault diagnosis on the first agricultural work vehicle (10) when the fault diagnosis module (230) determines that the first agricultural work vehicle (10) is normal is that the first agricultural work vehicle (10) is expensive equipment, so if the fault diagnosis module (230) determines that an abnormality has occurred, prompt action is required, and since it may be determined to be normal due to an error in the fault diagnosis module (230), the remote control server (330) performs an additional fault diagnosis to improve the accuracy of the fault diagnosis.

In the modified embodiment described above, whether or not to perform a fault diagnosis of the first agricultural work vehicle (10) by the remote control server (330) is determined based on the judgment result of the fault diagnosis module (230). However, in another modified embodiment, regardless of the judgment result of the fault diagnosis module (230), the fault diagnosis module (230) may primarily perform a fault diagnosis of the first agricultural work vehicle (10), and the remote control server (330) may secondarily perform a fault diagnosis of the first agricultural work vehicle (10).

According to another modified embodiment, even if the fault diagnosis module (230) determines that the first agricultural work vehicle (10) is abnormal, the remote control server (330) can perform a fault diagnosis. Accordingly, if the remote control server (330) determines that the first agricultural work vehicle (10) is abnormal based on the fault diagnosis results of the first agricultural work vehicle (10), the remote control server (330) can transmit the abnormality determination result to the fault diagnosis module (230). If the remote control server (330) determines that the first agricultural work vehicle (10) is normal based on the fault diagnosis results of the first agricultural work vehicle (10), the remote control server (330) can transmit the normal determination result to the fault diagnosis module (230).

In addition, if the first agricultural work vehicle (10) is determined to be normal by the fault diagnosis module (230), the remote control server (330) can perform a fault diagnosis. If the first agricultural work vehicle (10) is determined to be normal as a result of the fault diagnosis of the first agricultural work vehicle (10), the remote control server (330) can transmit a settlement determination result to the fault diagnosis module (230), and if the remote control server (330) determines that an abnormality has occurred in the first agricultural work vehicle (10), the remote control server (330) can transmit an abnormality determination result to the fault diagnosis module (230).

In this way, the present invention according to another modified embodiment has the effect of improving the accuracy of fault diagnosis by not only performing fault diagnosis primarily by the fault diagnosis module (230) but also performing fault diagnosis secondarily by the remote control server (330).

The second fault diagnosis system (335) can operate in a data collection mode by the remote control system (300) to collect data of the second agricultural work vehicle (340) for fault diagnosis of the first agricultural work vehicle (10). The second fault diagnosis system (335) can transmit data of the second agricultural work vehicle (340) to the remote control system (300) through wireless communication with the remote control system (300), and can collect data of the second agricultural work vehicle (340) through terminal communication or wireless communication with the second agricultural work vehicle (340).

The second fault diagnosis system (335) can diagnose whether the second agricultural work vehicle (340) is faulty by operating in fault diagnosis mode by the remote control system (300). Since the second fault diagnosis system (335) has the same function and configuration as the first fault diagnosis system (100), a detailed description thereof will be omitted.

The second agricultural work vehicle (340) may be of the same type as the first agricultural work vehicle (10) and may be a plurality of vehicles. Since the functions and configurations are the same as those of the first agricultural work vehicle (10), a detailed description will be omitted.

A person skilled in the art will appreciate that the present invention described above may be implemented in other specific forms without changing the technical idea or essential characteristics thereof.

Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive. The scope of the present invention is indicated by the claims described below rather than the detailed description above, and all changes or modifications derived from the meaning and scope of the claims and their equivalent concepts should be interpreted as being included in the scope of the present invention.
