Description

Management server for managing agricultural work vehicles and its management method {MANAGEMENT SERVER FOR MANAGING AGRICULTURAL WORKING VEHICLE AND MANAGING METHOD THEREROF}

The present invention relates to technology for managing agricultural work vehicles, and particularly to technology for predicting in advance the breakdown of agricultural work vehicles.

Agricultural work vehicles are vehicles used for agricultural work, and a representative example is an agricultural tractor.

Agricultural tractors can perform various types of agricultural work by attaching and detaching various implements.

The implement operates with driving force output from the engine of the agricultural tractor. Therefore, the driving and work of a farm tractor all affect the load on the engine.

However, excessive and continuous load on the engine while performing work may result in or result in a breakdown (engine failure, transmission failure, etc.) of the agricultural tractor. Therefore, in order to prevent users from experiencing unexpected failure situations, technologies are being proposed that notify users of a failure situation or notify them in advance that a failure may occur.

Among such technologies, there is a technology in which a management server remotely manages agricultural tractors using a communication network. The present invention relates to technology for managing agricultural tractors by such a management server.

The conventional management server is implemented to warn of a failure when a set value exceeds a certain value according to the engine load rate. Here, the set value is set based on the design and testing standards of agricultural tractors. For this purpose, the management server generates an alarm by comparing the engine load rate from the agricultural tractor during work with the settings set in the diagnostic module (including a controller with a diagnostic function) of the agricultural tractor based on the specification information of the agricultural tractor. Of course, the generated alarm reaches the agricultural tractor or the terminal of the user operating the agricultural tractor through the communication network.

However, agricultural tractors can be used in a variety of agricultural fields. And the working environment may be different for each farmland. For example, the soil quality is different for each farmland, so even if the work is the same, the load on the engine may vary in each farmland.

Therefore, if an alarm is generated based on a uniform set value according to the mechanical specifications of the agricultural tractor, too frequent alarms may be generated in some cases. Then, there is a problem of low management reliability, such as distracting the user's attention and causing disruption in agricultural work.

Preferred embodiments according to the present invention will be described with reference to the accompanying drawings, but for brevity of explanation, descriptions of well-known configurations will be omitted or compressed as much as possible.

Figure 1 is an example of an agricultural work system (AWS) to which the management server 200 according to the present invention is applied.

Agricultural work system) is implemented with an agricultural tractor 100 and a management server 200 interconnected by a communication network (TN).

The agricultural tractor 100 is equipped with a control unit 110, a diagnostic module 120, and a communication modem 130.

The control unit 100 controls various components (engine, automatic transmission, hydraulic motor, etc.) of the agricultural tractor 100. This control unit 100 collectively refers to all control means that control the necessary operations of the agricultural tractor 100, such as an engine control unit (ECU: Engine Control Unit) or a transmission control unit (TCU: Transmission Control Unit).

The control unit 100 needs to perform control that meets the specifications of various components that make up the agricultural tractor 100. For this purpose, the control unit 100 has specification information for various components. Here, the specification information includes information about the operating capabilities of the agricultural tractor 100, such as engine displacement or output, hydraulic output, gear speed, etc.

However, the specification information may be model information of the agricultural tractor 100. This is because if the management server 200 has all the specification information for each model of the agricultural tractor 100, the management server 200 can know all the specifications of the agricultural tractor 100 with only the model information. .

The diagnostic module 120 receives current operation information for each component from the control unit 110 and generates load information.

For example, the diagnostic module 120 receives information about the engine torque value from the control unit 110 and diagnoses the current engine load rate. For example, the diagnostic module 120 receives information about the engine's required torque value and actual output torque value in real time from the engine control unit, and determines the engine load in the area where the actual output torque value falls compared to the engine's required torque value. The judgment and engine load ratio can be diagnosed. Here, the engine load rate is included in the load information.

The diagnostic module 120 may be integrated with the control unit 110.

The communication modem 130 is provided for communication with the management server 200. The communication modem 130 can communicate with the management server 200 through a communication network (TN, including public network and private network).

Information transmitted from the agricultural tractor 100 to the management server 200 through the communication modem 130 includes location information, specification information, usage information, and load information. Here, location information, specification information, usage information, and load information are combined and defined as work information. That is, task information includes location information, specification information, usage information, and load information.

The location information is information about the location of the agricultural tractor 100. Therefore, location information makes it possible to specify the location of farmland. For this purpose, the communication modem 130 is equipped with a GPS module. Therefore, the communication modem 130 transmits location information of the agricultural tractor 100 to the management server 200 in addition to specification information, usage information, and load information.

Specification information is information about the specifications of the agricultural tractor 100. For example, specification information includes information such as engine output (horsepower), engine displacement, total shift speed of the transmission, and hydraulic motor output.

Usage information is information about the type of use of the agricultural tractor in operation. For example, usage information includes the speed of the agricultural tractor being worked on, the number of gears currently in use, work machine information that may affect the workload, such as the type of work machine or the length of the work machine, and the depth of work.

Load information is information about the load of the engine. Load information includes the engine load ratio for the load placed on the engine during work.

The management server 200 receives location information, specification information, usage information, and load information from the agricultural tractor 100, analyzes the received information, and generates a warning signal to predict failure of the agricultural tractor 100 in advance. This notifies the agricultural tractor 100 of a warning situation. For this purpose, the management server 200 includes a communication unit 210, a setting unit 220, a recording unit 230, an inquiry unit 240, and a determination unit 250.

The communication unit 210 is provided to communicate with the agricultural tractor 100. Specifically, the communication unit 210 communicates with the communication modem 130 through a communication network (TN). Therefore, the management server 200 can receive location information, specification information, usage information, and load information of the agricultural tractor 100 from the agricultural tractor 100 through the communication unit 210. Additionally, the management server 200 can notify the agricultural tractor 100 of a warning situation through the communication unit 210.

The setting unit 220 sets notification settings.

The notification setting value is a reference value for the management server 200 to generate a warning signal.

The notification setting value is a value set based on the engine load rate. For example, if the maximum output of the engine is 200, the notification setting value, which is the standard for generating a warning signal, may be set to 70%, which is 140, of the maximum output of the engine.

According to this embodiment, the notification setting value can be set in two paths.

The first path (first path) is a uniform setting path. For example, this is the path to set the notification setting value based on the load ratio of 70% compared to the engine's maximum output. In this case, when the engine load ratio reaches 70% in the load information coming from the agricultural tractor 100, the management server 200 generates a warning signal to notify the agricultural tractor 100 of the warning situation.

The second path (second path) is a characteristic path of the present invention, and is a path for setting notification settings using information on actual use of farmland and load information accompanying it.

For example, in the usage information when rotary work is performed on a specific farmland (location information) with a specific agricultural tractor 100 of a specific model (specification information), the engine load rate may be 60% on average. Then, the management server 200 sets the notification setting value when rotary work is performed in a specific farmland to 60%. Accordingly, if the engine load rate exceeds 60% when performing the same work in a specific farmland with a specific agricultural tractor (100) in the future, the management server (200) analyzes it as an output abnormality situation, and there is a possibility of a breakdown in the agricultural tractor (100). After determining that there is a warning signal, a warning signal is generated.

Of course, the engine load rate may vary at various points or sections of farmland. Therefore, if it is determined that there is a problem with the agricultural tractor 100 every time the engine load rate temporarily exceeds the notification setting value, frequent warnings may be generated. Therefore, the notification setting value may have a time element in addition to the engine load rate. For example, the notification setting value may further include elements such as the engine load rate exceeding 60% for 5 minutes and the engine load rate exceeding 70% for 3 minutes.

Additionally, in the second route, location information and specification information of the agricultural tractor 100 are needed in addition to use information and load information.

This embodiment is implemented to have both a first path and a second path. This will be explained in more detail later.

The recording unit 230 records and stores load information by connecting it to the location information, specification information, and use information of the agricultural tractor 100 received from the agricultural tractor 100 through the communication unit 210.

Recording and storage by the recording unit 230 can be implemented to continuously accumulate for each task.

Additionally, the recording unit 230 may be implemented to record and store the notification settings set in the setting unit 220.

When location information is received from the agricultural tractor 100 through the communication unit 210, the inquiry unit 240 searches the record unit 230 for a record having the same location information as the received location information. In one example, when location information with a latitude of 36.2500 and a longitude of 128.0000 is received, the management server 200 searches for a record of farmland with the same location information as the corresponding location information. Here, the record is work information (hereinafter referred to as 'inquiry information') including specification information and usage information of the agricultural tractor 100 used in the previous work. Additionally, there may be multiple pieces of work information with the corresponding location information.

Of course, there may be no records of work on farmland.

For example, there may be no record if work has not previously been performed using a farm tractor on the farmland in question.

For example, even if work was previously performed using a farm tractor on the farm in question, there may be no record if information was not collected.

However, the present invention has an important feature in that the previous work is performed on farmland, so records of the previous work can be searched.

The determination unit 250 compares the inquiry information received from the agricultural tractor 100 with the work information including specification information and usage information received through the communication unit 210 at the current time (hereinafter referred to as 'received information') to determine a schedule. When the conditions are met, a warning signal is generated to predict a failure. To this end, as shown in FIG. 3, the determination unit 250 includes a comparison means 251, a calculation means 252, and a notification means 253.

The comparison means 251 compares the inquiry information searched through the inquiry unit 240 and the reception information currently received through the communication unit 210.

For example, the comparison means 251 compares the specification information in the inquiry information with the specification information in the received information to compare whether the same agricultural tractor 100 is used for work as before.

For example, the comparison means 251 compares the use information in the inquiry information with the use information in the received information to determine whether the same operation is performed as before.

If the inquiry information and the received information match, the determination unit 250 generates a warning signal based on the notification setting value preset according to the load information in the previous job.

However, there may be differences between inquiry information and received information. Then, if a warning signal is generated based on the notification setting value set according to load information for previous work, too frequent warnings may be generated. Therefore, it must be calculated as a new standard for issuing warnings.

In addition, the comparison means 251 also has a function of comparing a notification setting value or a correction notification value to be described later with received information and a function of determining a warning about a breakdown of an agricultural work vehicle.

If there is a difference between the inquiry information and the received information in the comparison by the comparison means 251, the calculation means 252 calculates a correction notification value by reflecting a compensation coefficient equal to the difference in the notification setting value. Here, the compensation coefficient is a constant determined through experience and experiment.

For example, if the work speed in the received information is 0.1 km/h higher than the work speed in the inquiry information, the load on the engine increases as the speed of the agricultural tractor 100 increases. Therefore, if the notification setting value is set to 70%, the calculation means 252 calculates the correction notification value by reflecting the compensation coefficient corresponding to the speed increase of 0.1 km/h. In one example, if the compensation coefficient is determined to be 1% per 0.1 km/h, the calculation means 252 calculates 71%, which reflects the compensation coefficient of 1% in the notification setting value of 70%, as a correction notification value.

When the correction notification value is calculated by the calculation means 253, the notification means 253 generates a warning signal based on the correction notification value and transmits it to the agricultural tractor 100. For example, if the engine load rate currently received during work through the communication unit 210 exceeds the correction notification value for a set period of 5 minutes, the notification means 253 generates a warning signal and transmits it to the agricultural tractor 100.

Meanwhile, the recorder 230 connects the load information to the received information from the start to the end of the work even in the work currently taking place in the relevant farmland, and continuously accumulates, records, and stores it. And the setting unit 220 sets the notification setting value to the engine load rate among the load information accumulated, recorded and stored by the recording unit 230. For example, the notification setting value may be the average value of the accumulated engine load rate.

Of course, the set notification settings may be recorded and stored by the recording unit 230, or may be implemented so that the setting unit 220 itself records and stores them.

<Description of location information and correction notification values>

The present invention has two important features: identifying farmland through location information and calculating a correction notification value by reflecting the compensation coefficient in the notification setting value. Therefore, the calculation of location information and correction notification values will be explained in more detail.

1. Location information related

For example, even if work is performed with the same agricultural tractor 100 and implement, the load on the engine is different from the load on the engine when working on farmland with soft soil (hereinafter referred to as 'first farmland') and farmland with hard soil (hereinafter referred to as 'second farmland'). The load on the engine is different when working on (referred to as ‘farmland’). On the other hand, the same farmland will usually have the same engine load ratio.

Therefore, in the present invention, when location information is received from the agricultural tractor 100 on which work is to be performed, records of farmland with the same location information as the received location information are searched, and based on the notification setting value in the searched record, Measures are being taken to generate warning signals.

Therefore, according to the present invention, the notification setting value in the first farmland and the notification setting value in the second farmland are different. For example, if the notification setting value in the first farmland has an engine load rate of 70%, the notification setting value in the second farmland may have an engine load rate of 75%.

Therefore, the present invention makes it possible to manage the agricultural tractor 100 with notification settings suited to the characteristics of the farmland.

2. Correction notification value related

The same work as the past work can be performed on the same farmland with the same agricultural tractor 100. At this time, the current task may have the same engine load rate as the past task. Therefore, the management server 200 only needs to generate a warning signal based on the notification setting value set using the engine load rate in past work. In this case, the load information according to the current work is continuously recorded and stored by the recording unit 230, and the notification setting value can be implemented to be updated to reflect the current work accumulation.

However, there are several factors that cause current operations to have different engine load rates than past operations.

One factor may be the speed of operation. This is because as the work speed changes, the engine load factor also changes.

One factor may be work machine information that may affect the workload, such as the type of work machine or the length of the work machine. This is because as the work machine information changes, the engine load rate also changes.

One factor may be the depth of work. This is because as the working depth changes, the engine load rate also changes.

If a warning signal is generated based on a notification setting value set based on past work even though various factors that cause the engine load rate to vary have changed, an appropriate warning cannot be generated.

Therefore, customized management that generates a warning signal based on the corrected notification value that corrects the notification setting value is required. To this end, in the present invention, it is necessary to determine a compensation coefficient for each factor that changes the engine load rate. For example, the compensation coefficient can be determined as 1% per 0.1km increase in work speed, 1% per 10cm increase in work tool length, and 1% per 2cm increase in work depth. So, if the current work is performed with the work speed, tool length, and work depth increased by 0.2km, 0.5m, and 1cm, respectively, compared to the past work, the correction notification value is the notification setting value (70%) plus the work speed increase (2%). ), the increase in working machine length (5%) and the increase in working depth (0.5%) are reflected to calculate 77.5%.

So, according to one example, the management server 200 operates to generate a warning signal when the engine load ratio among the load information received during the current work exceeds 77.5%, which is the correction notification value, for 5 consecutive minutes. Accordingly, the management server 200 according to the present invention can generate a customized warning.

Additionally, even when agricultural tractors 100 with different specifications are used, it may be inappropriate to generate a warning signal based on the notification setting value set based on past work history.

For example, if the same work is performed with the same implement on the same farmland as in the past using a farm tractor 100 with the same engine displacement but different engine output, the engine load rate may vary as the engine output is different. Therefore, the compensation coefficient according to the engine output can be determined, and the correction notification value can be calculated by reflecting the compensation coefficient according to the decrease in engine output.

In addition, even when using the agricultural tractor 100 with a lower engine displacement than in past work, a correction notification value reflecting the lower engine displacement can be calculated.

However, the maximum output of the engine must not exceed 100%, and if the correction notification value is set too high, the agricultural tractor 100 may work for a long time in an overloaded state and may malfunction. Therefore, for example, the maximum value of the correction notification value needs to be calculated so that it does not exceed 90%. In other words, the correction notification value needs to be calculated within a limited value.

<Description of management method>

The management method according to the present invention performed in the management server 200 will be described with reference to the flowchart of FIG. 4.

1. Information record<S41>

The recording unit 230 of the management server 200 records and stores the location information, specification information, use information, and load information of the agricultural tractor 100 received from the agricultural tractor 100. Here, load information is continuously received from the agricultural tractor 100 from the beginning to the end of work, and the received load information is linked to location information, specification information, and usage information and is accumulated. In other words, the work information of agricultural work vehicles is continuously recorded and stored from the start of work to the end. And the accumulated load information is used to set or update notification settings, which will be described later.

2. Record inquiry<S42>

When the location information and reception information are received from the agricultural tractor 100 after step S41, the inquiry unit 240 of the management server 200 searches for a record having the same location information as the received location information.

If the same location information as the received location information is not searched, the management server 200 is implemented to generate a warning signal using the initial setting value as the notification setting value in step S48, which will be described later.

3. Setting notification settings <S43>

The setting unit 220 of the management server 200 sets a notification setting value for the engine load rate of the agricultural tractor 100.

The notification setting value can be set to the first path and the second path as described above.

The first path may be a uniformly set value. The first route is used when there is no record of previous work on a specific farmland. That is, if there is no step S41, the notification setting value is set according to the first path. The notification setting value set according to the first path may be called the initial setting value.

Setting of the initial setting value is made before step S41.

The initial setting value may be implemented so that the management server 200 sets itself to a constant value. If there is no record of a specific farmland, for example, the engine load rate of the agricultural tractor 100 currently performing work may be set to 70% (for more than 5 minutes continuously) as a notification setting value.

However, work has previously been performed on the farmland in question by the agricultural tractor 100, and there may be a record of the work. Then, since step S41 has been passed, the setting unit 220 of the management server 200 can set the notification setting value using the second path.

The notification setting value according to the second path is set based on the record of previously performed work. Therefore, after going through step S42, the management server sets the notification setting value using the engine load rate among records of previous work.

For example, the setting unit 220 may set the average value of the engine load rate among the load information accumulated from the start to the end of the work in the record as the notification setting value. Of course, notification settings are set in conjunction with location information, specification information, and usage information.

In addition, the set notification setting value can be continuously updated by reflecting load information received and accumulated from the same agricultural tractor 100 in the same farmland in the future. According to one example, the average value of the engine load rate accumulated by multiple tasks may be continuously updated as the notification setting value.

However, if the notification setting value set through the second path is smaller than the notification setting value set through the first path, the setting unit 220 sets the notification setting value set according to the first path to the initial setting value. It may be more desirable to consider implementing it to do so.

4. Compare information<S44>

The comparison means 251 compares the inquiry information searched in step S43 with the currently received reception information.

If the inquiry information and the received information are the same, the determination unit 250 is implemented to generate a warning signal based on the notification setting value set in step S48, which will be described later.

However, if the inquiry information and the received information do not match and a difference is confirmed, the determination unit 250 operates the calculation means 252 to calculate a correction notification value.

Regarding this step S44, reference may be made to the example in FIG. 5.

Referring to Figure 5, is it the same model (same specifications)? <S44a>, is the work speed the same? <S44b>, is the work machine load the same? <S44c>, is the work depth the same? <S44d>. A comparison is made.

Therefore, if there is a difference in elements for each comparison, the compensation coefficient determined for each element is reflected in the correction notification value calculation <S46>, which will be described later.

However, the comparison in FIG. 5 shows that engine performance correction, speed correction, work tool correction, and depth correction are performed sequentially. However, the order of comparison or correction may be implemented differently, or may be implemented so that they are performed uniformly.

5. Check failure history <S45>

After the comparison is made in step S44, the management server 200 checks whether there is a failure history (repair history) for the corresponding agricultural tractor 100.

If there is a failure history, the stored record may be an incorrect record due to the failure, so the determination unit 253 generates a warning signal with the initial setting value or the notification setting value set before the failure in step S47, which will be described later. That is, when there is a failure history, the management server 200 is implemented to generate a warning signal with a notification setting value excluding records related to the failure history.

For reference, step S45 may be performed before step S44.

6. Calculation of correction notification value <S46>

If the accident history is not confirmed in step S45, the calculation means 252 calculates a correction notification value by reflecting the compensation coefficient according to the comparison in step S44 to the set notification setting value.

Depending on implementation, if the failure history is confirmed in step S45, the correction notification value may be determined as an initial setting value.

Depending on implementation, if the failure history is confirmed in step S45, the correction notification value may be calculated using only the remaining work information excluding the work information related to the failure.

7. Comparison of correction notification value and work information <S47>

When the correction notification value is calculated in step S46, the comparison means 251 of the determination unit 250 compares the correction notification value with the received work information.

Of course, in some cases, calculation of the correction notification value may not be required. In this case, the comparison means 251 compares the notification setting value and the received information.

8. Warning signal generation and notification <S47>

Thereafter, according to the comparison in step S47>, the notification means 253 generates a warning signal when an engine load rate exceeding the correction notification value is continuously received for a predetermined time based on the correction notification value and transmits it to the agricultural tractor 100. If calculation of the correction notification value is not required, the notification means 253 generates a warning signal when an engine load rate exceeding the notification setting value is continuously received for a set time based on the notification setting value, and this is used as a general tractor. Send to (100).

For reference, even while the current work is being performed, the recording unit 230 records the load information continuously received from the agricultural tractor 100 by linking it with the received information <S41>, and the setting unit 220 records accumulated information in the future. For this, the notification setting value according to the second path is set <S43>. In other words, management in currently performed work is done based on work performed in the past, but step S41 is performed in currently performed work, and step S43 is performed later.

<Additional information>

1. Priority

The present invention manages the user to respond in advance to the breakdown of the agricultural tractor 100 by generating a warning before the breakdown of the agricultural tractor 100. To this end, it is implemented to generate a warning based on the notification settings set based on records of past work.

Therefore, the notification setting value set based on past records of work on the same farmland becomes the standard for issuing a warning. At this time, there may be multiple past records.

If there is a record that matches the inquiry information and the received information, the management server 200 generates a warning based on the notification setting value according to the matching record.

However, if the inquiry information and received information do not match, the management server 200 calculates a correction notification value based on records where the inquiry information and received information are as similar as possible, and generates a warning based on the calculated correction notification value.

If there is no past record of work on the same farmland, the management server 200 generates a warning using the initial setting value as the standard for generating the warning.

2. Limit correction notification value

According to one embodiment of the present invention, the upper limit of the correction notification value is limited. Therefore, if the correction notification value reflecting the compensation coefficient exceeds the upper limit, the correction notification value is calculated as the upper limit, and this situation is notified to the agricultural tractor 100.

3. Agricultural work vehicles

The above embodiment relates to the agricultural tractor 100, but the present invention can be applied to all agricultural work vehicles that can be used for agricultural work in addition to the agricultural tractor 100.

The above-described embodiments are only described as preferred examples of the present invention, and may have various application forms. Therefore, the present invention should not be understood as limited to the content described above. Instead, the scope of rights of the present invention should be understood as the separately stated claims and their equivalents.
