Description

[Technical field]

[0001] The present invention relates to a management system for agricultural machinery and an electronic device used in the management system. [Background technology]

[0002] In agricultural work, various agricultural machines such as the boom sprayer described in Patent Document 1 are used. Maintenance work is performed on such agricultural machines so that the agricultural machines can be used appropriately. In addition, agricultural machines are known that are provided with an hour meter that notifies the user of the operation time of the agricultural machine so that the user can know the timing of maintenance work. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2021-40534 A Summary of the Invention [Problem to be solved by the invention]

[0004] When an agricultural machine is provided with an hour meter, the user of the agricultural machine can know whether or not maintenance work is required. However, unlike automobiles, agricultural machines do not require legal maintenance. Therefore, even if an agricultural machine is provided with an hour meter, maintenance work will not be performed unless the user determines that maintenance work is required. For this reason, in the field of agricultural machines, there is a demand for a configuration that can manage whether or not maintenance work is required for agricultural machines and notify the user that maintenance work is required. [Means for solving the problem]

[0005] A first aspect of the present invention is a management system (100) that notifies maintenance information to encourage maintenance work on an agricultural machine (A), and includes an electronic device (10) provided in the agricultural machine (A) and a server device (20) that communicates with the electronic device (10) via a communication network (N). The electronic device (10) includes a time measurement unit (11) that measures an operating time of the agricultural machine (A) and a transmission unit (22) that transmits operating time information including the operating time measured by the time measurement unit (11) to the server device (20) via the communication network (N). The server device (20) has a receiving unit (21) that receives driving time information from the electronic device (10), a maintenance determination unit (23) that determines whether or not maintenance work is required for the agricultural machine (A) based on the driving time included in the driving time information received by the receiving unit (21), and a notification unit (24) that notifies the maintenance information when the maintenance determination unit (23) determines that maintenance work is required, and the maintenance determination unit (23) determines that maintenance work is required when the driving time exceeds a predetermined driving time determination threshold.

[0006] In this management system (100), the electronic device (10) can transmit operating time information of the agricultural machine (A) to the server device (20). This enables the server device (20) to collect the operating time of the agricultural machine (A). The server device (20) then determines whether or not maintenance work is required based on the operating time. If maintenance work is required, the server device (20) can notify the user of the maintenance information. In this manner, the management system (100) can manage whether or not maintenance work is required for the agricultural machine (A) and notify the user that maintenance work is required.

[0007] In the above management system (100), the server device (20) further includes a wear condition acquisition unit (22) that acquires the degree of wear of the agricultural machine (A) confirmed by the maintenance work, and the maintenance determination unit (23) may set the operation time determination threshold to be smaller when the degree of wear acquired by the wear condition acquisition unit (22) is high than when the degree of wear is low. In this case, the server device (20) can more appropriately determine whether or not maintenance work is required depending on the actual degree of wear.

[0008] In the above management system (100), the time measurement unit (11) measures the operation time of each of the multiple elements of the agricultural machine (A), an operation time determination threshold is set for each element, the maintenance determination unit (23) determines whether or not maintenance work is required for each element, and the notification unit (24) may notify maintenance information for the element determined to require maintenance work. In this case, the management system (100) can determine whether or not maintenance work is required for each element of the agricultural machine (A).

[0009] A second aspect of the present invention is a management system (100) that notifies the user of maintenance information to encourage maintenance work on an agricultural machine (A), and the management system (100) includes an electronic device (10) provided on the agricultural machine (A) and a server device (20) that communicates with the electronic device (10) via a communication network (N). The electronic device (10) includes a vibration detection unit (12) that detects vibrations generated in the agricultural machine (A), and a transmission unit (13) that transmits vibration information including a detection result of the vibration detection unit (12) to the server device (20) via the communication network (N). The server device (20) includes a receiving unit (21) that receives vibration information from the electronic device (10), a maintenance determination unit (23) that determines whether or not maintenance work is required for the agricultural machine (A) based on the vibration information received by the receiving unit (21), and a notification unit (24) that notifies the user of maintenance information when it is determined by the maintenance determination unit (23) that maintenance work is required. The maintenance determination unit (23) determines an effective value of the vibration, a value indicating the occurrence of the vibration, and a notification unit (24) that notifies the user of maintenance information. The necessity of maintenance work is determined based on at least one of the accumulated time during which vibration is generated and the number of times the vibration magnitude exceeded a predetermined value; when the effective value of the vibration is used, it is determined that maintenance work is needed sooner when the effective value of the vibration is high compared to when the effective value of the vibration is low, or it is determined that maintenance work is needed when the effective value of the vibration exceeds a predetermined effective value threshold; when the accumulated time while vibration is generated is used, it is determined that maintenance work is needed sooner when the accumulated time is long compared to when the accumulated time is short, or it is determined that maintenance work is needed when the accumulated time exceeds a predetermined accumulated time threshold; when the number of times the vibration magnitude exceeded a predetermined value is used, it is determined that maintenance work is needed sooner when the number of times the vibration exceeded the predetermined magnitude is high compared to when the number of times is low, or it is determined that maintenance work is needed when the number of times the vibration exceeded the predetermined magnitude exceeds a predetermined number threshold.

[0010] In this management system (100), the electronic device (10) can transmit vibration information of the agricultural machine (A) to the server device (20). This enables the server device (20) to collect the vibration information of the agricultural machine (A). The server device (20) then determines whether or not maintenance work is required based on the vibration information. If maintenance work is required, the server device (20) can notify the maintenance information. In this way, the management system (100) can manage whether or not maintenance work is required for the agricultural machine (A) and notify the fact that maintenance work is required.

[0011] In the above management system (100), the server device (20) further includes a wear condition acquisition unit (22) that acquires the degree of wear of the agricultural machine (A) confirmed by the maintenance work, and the maintenance determination unit (23) may determine that maintenance work is needed sooner when the degree of wear acquired by the wear condition acquisition unit (22) is high than when the degree of wear is low, or may reduce at least any one of the effective value threshold, the integrated time threshold, and the number threshold. In this case, the server device (20) can more appropriately determine whether or not maintenance work is needed depending on the actual degree of wear.

[0012] A third aspect of the present invention is an electronic device (10) that is used in a management system (100) that notifies maintenance information to prompt maintenance work on the agricultural machine (A) and is provided on the agricultural machine (A), the electronic device (10) comprising: a time measurement unit (11) that measures the operating time of the agricultural machine (A); and a transmission unit (13) that transmits operating time information including the operating time measured by the time measurement unit (11) to a server device (20) of the management system (100) via a communication network (N).

[0013] The electronic device 10 can transmit operation time information of the agricultural machine A to the server device 20. This enables the server device 20 to determine whether or not maintenance work is required for the agricultural machine A, based on the operation time information received from the electronic device 10. In this manner, by using the electronic device 10, it is possible to easily manage whether or not maintenance work is required for the agricultural machine A.

[0014] A fourth aspect of the present invention is an electronic device (10) used in a management system (100) that notifies maintenance information to encourage maintenance work on an agricultural machine (A) and is provided on the agricultural machine (A), the electronic device (10) including a vibration detection unit (12) that detects vibrations generated in the agricultural machine (A) and a transmission unit (13) that transmits vibration information including the detection results of the vibration detection unit (12) to a server device (20) of the management system (100) via a communication network (N).

[0015] The electronic device 10 can transmit vibration information of the agricultural machine A to the server device 20. This allows the server device 20 to determine whether or not the agricultural machine A requires maintenance work, based on the vibration information received from the electronic device 10. In this way, by using the electronic device 10, it is possible to easily manage whether or not the agricultural machine A requires maintenance work. Effect of the Invention

[0016] According to various aspects of the present invention, it is possible to manage whether or not maintenance work is required for an agricultural machine, and to notify the user that maintenance work is required. [Brief description of the drawings]

[0017] [Figure 1] FIG. 1 is a diagram showing a schematic configuration of a management system according to an embodiment. [Diagram 2] FIG. 2 is a flowchart showing the flow of a process for determining whether or not maintenance work is required, which is performed in the server device. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In each drawing, the same or corresponding elements are denoted by the same reference numerals, and duplicated explanations will be omitted.

[0019] 1, the management system 100 manages maintenance work of one or more agricultural machines A. The management system 100 notifies a user of the agricultural machine A, a maintenance contractor (maintenance factory), a person in charge at a dealer of the agricultural machine A, and the like of maintenance information that prompts maintenance work of the agricultural machine A. The agricultural machine A may be any of a self-propelled vehicle, a machine coupled with a tractor to perform various tasks, a stationary machine or a machine loaded on a truck, a small portable machine, and the like.

[0020] The management system 100 includes an electronic device 10 and a server device 20. The electronic device 10 and the server device 20 are connected to a communication network N. The communication network N is, for example, a wide area network such as the Internet, but may also be a local area network. The communication network N may also be a wired network, a wireless network, or a combination of a wired network and a wireless network. The electronic device 10 is connected to the communication network N by wireless communication.

[0021] The electronic device 10 is provided in the agricultural machine A. The electronic device 10 is an electronic control unit having, for example, a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), a communication device, etc. The electronic device 10 realizes various functions by, for example, loading a program recorded in the ROM into the RAM and executing the program loaded into the RAM by the CPU.

[0022] The electronic device 10 functionally includes a time measurement unit 11, a vibration detection unit 12, and a transmission unit 13. The time measurement unit 11 measures the operation time of the agricultural machine A. The operation time may be at least one of an accumulated time when the power supply of the agricultural machine A is ON and an accumulated time when an element of the agricultural machine A is operating. For example, even if the power supply of the electronic device 10 is OFF, the time measurement unit 11 stores the operation time immediately before the power supply is OFF. For example, when the power supply of the electronic device 10 is ON again, the time measurement unit 11 measures the time from the stored operation time. For example, the time measurement unit 11 may periodically save the operation time in a non-volatile memory (not shown) or the like, and read the operation time from the non-volatile memory when the power supply of the electronic device 10 is ON.

[0023] The time measurement unit 11 can measure the operation time of each of the multiple elements equipped in the agricultural machine A. For example, the multiple elements equipped in the agricultural machine A may include moving parts such as an engine, a pump, and an electric motor. The multiple elements equipped in the agricultural machine A may also include equipment other than moving parts such as a battery and a tank. The multiple elements equipped in the agricultural machine A may also be equipment that is the target of maintenance work.

[0024] The time measurement unit 11 may measure the operation time based on the main voltage of the electrical equipment equipped in the agricultural machine A. The time measurement unit 11 may measure the operation time of a moving part that is rotationally driven by an engine, a pump, or the like, or the operation time of the engine, pump, or the like, based on the rotation state of the engine, pump, or the like obtained using a rotation sensor. The time measurement unit 11 may measure the operation time of the moving part or the operation time of the electric motor based on the current flowing through the electric motor that drives the moving part.

[0025] The vibration detection unit 12 detects vibrations occurring in the agricultural machine A. This vibration may be vibrations caused by unevenness of the road surface when the agricultural machine A such as a tractor is traveling. The vibration detection unit 12 can detect the vibrations using various sensors such as a piezoelectric sensor or a MEMS acceleration sensor. The vibration detection unit 12 detects at least one of the following as the vibration: the effective value of the vibration, the accumulated time during which the vibration is occurring, and the number of times that the magnitude of the vibration (the magnitude of the amplitude of the vibration (voltage waveform)) exceeds a predetermined value.

[0026] The transmission unit 13 communicates with the server device 20 via the communication network N. The transmission unit 13 transmits driving time information including the driving time measured by the time measurement unit 11 and vibration information including the detection result of the vibration detection unit 12 to the server device 20 via the communication network N. Note that the driving time may be measured for each element of the agricultural machine A by the time measurement unit 11. In this case, the maintenance judgment unit 23 generates driving time information including a plurality of driving times for each element of the agricultural machine A. Each of the plurality of driving times included in the driving time information is associated with element information for identifying the element so that it is possible to distinguish which element the driving time is. The transmission unit 13 transmits the driving time information and vibration information in association with identification information for identifying the agricultural machine A. When the transmission unit 13 is in a state where it can communicate with the server device 20, the transmission unit 13 transmits the driving time information and the like to the server device 20 at predetermined time intervals (for example, every 5 minutes).

[0027] The server device 20 communicates with the electronic device 10 via a communication network N. The server device 20 is configured as an electronic control unit similar to the electronic device 10. The server device 20 includes a receiving unit 21, a wear state acquiring unit 22, a maintenance determining unit 23, and a notifying unit 24. The server device 20 may be configured as a cloud server on the Internet. Furthermore, each function of the server device 20 may be realized by a web application configured on the cloud server.

[0028] The receiving unit 21 receives the driving time information and the vibration information transmitted from the electronic device 10 via the communication network N.

[0029] The wear condition acquisition unit 22 acquires the degree of wear of the agricultural machine A that was confirmed when maintenance work was performed on the agricultural machine A. As will be described in detail later, the worker or the like who performed maintenance work on the agricultural machine A inputs to the server device 20 the fact that they performed the maintenance work, as well as the degree of wear of the elements on which the maintenance work was performed. The wear condition acquisition unit 22 acquires this input degree of wear. This degree of wear is associated with identification information of the agricultural machine A. In addition, the wear condition acquisition unit 22 acquires the degree of wear for each element of the agricultural machine A on which maintenance work was performed.

[0030] The maintenance determination unit 23 determines whether or not maintenance work is necessary for the agricultural machine A by using a first method and a second method. The maintenance determination unit 23 determines whether or not maintenance work is necessary by using either the first method or the second method. Furthermore, the maintenance determination unit 23 may determine that maintenance work is necessary for the agricultural machine A when it is determined that maintenance work is necessary by both the first method and the second method.

[0031] (First Method) As a first method, the maintenance determination unit 23 determines whether or not maintenance work is required for the agricultural machine A based on the driving time included in the driving time information received by the receiving unit 21. The maintenance determination unit 23 determines that maintenance work is required when the driving time exceeds a predetermined driving time determination threshold. Note that the driving time information may include driving times for multiple elements. In this case, the maintenance determination unit 23 determines whether or not maintenance work is required for each element by comparing the driving time determination threshold set for each element with the driving time for each element. Note that the maintenance determination unit 23 determines whether or not maintenance work is required by comparing the driving time since the previous maintenance work was performed with the driving time determination threshold.

[0032] The driving time judgment threshold used by the maintenance judgment unit 23 for judgment is set for each agricultural machine A. The maintenance judgment unit 23 judges whether or not maintenance work is necessary using the driving time judgment threshold corresponding to the agricultural machine A to be judged. Note that the driving time judgment threshold is associated in advance with the identification information of the agricultural machine A. For this reason, the maintenance judgment unit 23 can specify the driving time judgment threshold used for judgment, based on the identification information of the agricultural machine A associated with the driving time information and the identification information of the agricultural machine A associated with the driving time judgment threshold.

[0033] The maintenance judgment unit 23 can change the driving time judgment threshold based on the degree of wear acquired by the wear condition acquisition unit 22. Specifically, when the acquired degree of wear is high, the maintenance judgment unit 23 reduces the driving time judgment threshold compared to when the degree of wear is low. The maintenance judgment unit 23 specifies the driving time judgment threshold of the agricultural machine A to be changed based on the identification information of the agricultural machine A associated with the acquired degree of wear. In other words, the maintenance judgment unit 23 changes the driving time judgment threshold of the agricultural machine A on which maintenance work has been performed, based on the result of maintenance work on the agricultural machine A. When the degree of wear is acquired for each element of the agricultural machine A by the wear condition acquisition unit 22, the maintenance judgment unit 23 changes the driving time judgment threshold corresponding to the element of the acquired degree of wear.

[0034] (Second Method) As a second method, the maintenance determination unit 23 determines whether or not maintenance work is required for the agricultural machine A based on the vibration detection results included in the vibration information received by the receiving unit 21. Here, fatigue due to vibration is known to be one of the causes of failures in the agricultural machine A. As an analysis of fatigue due to vibration, for example, a method using the cumulative damage degree is known. As such, there is a correlation between various aspects of vibration and fatigue. The maintenance determination unit 23 determines whether or not maintenance work is required based on at least one of the effective value of the vibration, the accumulated time during which the vibration is occurring, and the number of times the vibration exceeds a predetermined magnitude.

[0035] Specifically, when the maintenance determination unit 23 uses the effective value of the vibration, it determines that maintenance work is needed sooner when the effective value of the vibration is high than when the effective value of the vibration is low. When the maintenance determination unit 23 uses the accumulated time during which the vibration is occurring, it determines that maintenance work is needed sooner when the accumulated time is long than when the accumulated time is short. When the maintenance determination unit 23 uses the number of times that the vibration exceeds a predetermined magnitude, it determines that maintenance work is needed sooner when the number of times that the vibration exceeds the predetermined magnitude is high than when the number of times is low.

[0036] For example, the maintenance assessment unit 23 can determine whether or not maintenance work is required based on a method obtained through empirical learning by comprehensively analyzing at least one of the effective value of the vibration, the accumulated time during which the vibration is occurring, and the number of times the vibration exceeded a predetermined magnitude, as well as the degree of wear.

[0037] The maintenance determination unit 23 can change the timing at which it is determined that maintenance work is necessary, based on the degree of wear acquired by the wear condition acquisition unit 22. Specifically, when the acquired degree of wear is high, the maintenance determination unit 23 determines that maintenance work is necessary earlier than when the degree of wear is low. The maintenance determination unit 23 identifies the agricultural machine A that is the target for changing the timing at which it is determined that maintenance is necessary, based on the identification information of the agricultural machine A associated with the acquired degree of wear. In other words, the maintenance determination unit 23 changes the maintenance timing of the agricultural machine A on which maintenance work has been performed, based on the results of the maintenance work on the agricultural machine A.

[0038] Furthermore, in the case where the effective value of the vibration is used, the maintenance determination unit 23 can determine that maintenance work is necessary when the effective value of the vibration exceeds a predetermined effective value threshold. In the case where the accumulated time during which the vibration is generated is used, the maintenance determination unit 23 can also determine that maintenance work is necessary when the accumulated time exceeds a predetermined accumulated time threshold. In the case where the number of times the magnitude of the vibration exceeds a predetermined value is used, the maintenance determination unit 23 can also determine that maintenance work is necessary when the number of times the vibration exceeds the predetermined magnitude exceeds a predetermined number threshold. The maintenance determination unit 23 may determine that maintenance work is necessary when a condition is satisfied in any one of the cases of using the effective value of the vibration, using the accumulated time during which the vibration is generated, and using the number of times the magnitude of the vibration exceeds a predetermined value, or may determine that maintenance work is necessary when a condition is satisfied in any two or more cases.

[0039] The effective value threshold, integrated time threshold, and number threshold used by the maintenance judgment unit 23 when making a judgment are set for each agricultural machine A. The maintenance judgment unit 23 judges whether or not maintenance work is necessary using the effective value threshold, etc. corresponding to the agricultural machine A to be judged. The effective value threshold, etc. are associated in advance with the identification information of the agricultural machine A. For this reason, the maintenance judgment unit 23 can specify the effective value threshold, etc. to be used for judgment, based on the identification information of the agricultural machine A associated with the vibration information and the identification information of the agricultural machine A associated with the effective value threshold, etc.

[0040] The maintenance determination unit 23 can change at least one of the effective value threshold, the accumulated time threshold, and the number threshold, based on the degree of wear acquired by the wear state acquisition unit 22. Specifically, when the acquired degree of wear is high, the maintenance determination unit 23 reduces at least one of the effective value threshold, the accumulated time threshold, and the number threshold, compared to when the degree of wear is low. Note that the maintenance determination unit 23 specifies the effective value threshold, etc. of the agricultural machine A to be changed, based on the identification information of the agricultural machine A associated with the acquired degree of wear. In other words, the maintenance determination unit 23 changes the effective value threshold of the agricultural machine A on which maintenance work has been performed, based on the result of maintenance work on the agricultural machine A.

[0041] Furthermore, the server device 20 can receive the degree of wear for a plurality of agricultural machines A. In this case, the maintenance determination unit 23 may change the driving time determination threshold used in the first method and the effective value threshold used in the second method, etc., based on the degree of wear for the other agricultural machines A. At that time, the maintenance determination unit 23 may change the driving time determination threshold etc. of the agricultural machine A to be changed based on the degree of wear of the other agricultural machines A having similar usage conditions (purpose of use, season, region, etc.) to the agricultural machine A to be changed in the driving time determination threshold etc.

[0042] When the maintenance determination unit 23 determines that maintenance work is necessary, the notification unit 24 notifies the user of maintenance information that prompts the user to perform the maintenance work. Furthermore, when the necessity of maintenance work has been determined for each element of the agricultural machine A, the notification unit 24 notifies the user of maintenance information for the element determined to require maintenance work.

[0043] The notification unit 24 can notify the maintenance information by various methods in order to notify that maintenance work is necessary. The destination of the notification of the maintenance information may be set in advance. For example, the notification unit 24 notifies the maintenance information to at least one of the user of the agricultural machine A, the maintenance contractor (maintenance shop), and the person in charge at the dealer of the agricultural machine A. For example, the notification unit 24 may use email as a method of notifying the maintenance information, or may display the maintenance information on a monitor installed at the destination or on a monitor of a mobile terminal.

[0044] After the maintenance work of the agricultural machine A is performed based on the notification of the maintenance information, the maintenance contractor inputs to the management system 100 that the maintenance work has been completed. This input may be performed, for example, using a maintenance contractor terminal 30 installed in a maintenance factory. The maintenance contractor terminal 30 is communicatively connected to the server device 20 via the communication network N. The receiving unit 21 receives an input to the effect that the maintenance work has been completed from the maintenance contractor terminal 30 via the communication network N. As a result, the maintenance determination unit 23 of the server device 20 resets the count of the operating time of the agricultural machine A for which the maintenance work has been completed, and then starts counting the operating time again based on the reception result of the receiving unit 21. In addition, the maintenance determination unit 23 may reset the count of the integrated time when vibration is occurring and the count of the number of times that vibration has exceeded a predetermined magnitude, together with resetting the count of the operating time.

[0045] The maintenance contractor also inputs the degree of wear of each element to the management system 100 along with a notification that the maintenance work has been completed. This input may be made, for example, using a maintenance contractor terminal 30 installed in a maintenance factory. The receiving unit 21 also receives the input degree of wear. Based on this degree of wear, the maintenance determination unit 23 changes the driving time determination threshold and the timing for determining that maintenance work is necessary. This change may be made, for example, when the degree of wear is equal to or greater than a predetermined level.

[0046] Next, the flow of the notification process of the maintenance information performed by the server device 20 of the management system 100 will be described with reference to FIG. 2. In the process shown in FIG. 2, after the process reaches the end, the process is started again after a predetermined time. As shown in FIG. 2, the receiving unit 21 judges whether or not the driving time information and / or the vibration information is received from the electronic device 10 (S101). When the maintenance judgment unit 23 performs the judgment by the first method described above, the receiving unit 21 judges whether or not the driving time information is received. When the maintenance judgment unit 23 performs the judgment by the second method described above, the receiving unit 21 judges whether or not the vibration information is received. When the maintenance judgment unit 23 performs the judgment by combining the first method and the second method described above, the receiving unit 21 judges whether or not the driving time information and the vibration information are received.

[0047] If it is determined in S101 that no information has been received (S101: NO), the process is restarted from the start after a predetermined time has elapsed. If it is determined in S101 that information has been received (S101: YES), the maintenance determination unit 23 determines whether or not maintenance work has been performed on the agricultural machine A based on the received information (S102). Here, the maintenance determination unit 23 makes the determination based on the first method and / or the second method described above.

[0048] If it is determined in S102 that maintenance work is not required (S102: NO), the process is restarted from the start after a predetermined time. If it is determined in S102 that maintenance work is required (S102: YES), the notification unit 24 notifies the user, etc. of the agricultural machine A of maintenance information that prompts the user to perform the maintenance work (S103). As a result, the maintenance work of the agricultural machine A is performed in the maintenance workshop.

[0049] After notifying the maintenance information, the receiving unit 21 judges whether or not an input has been made to the effect that the maintenance work has been completed (S104). If an input to the effect that the maintenance work has been completed has not been made (S104: NO), the receiving unit 21 performs the judgment of S104 again. If an input to the effect that the maintenance work has been completed has been made (S104: YES), the maintenance judgment unit 23 resets the count of the driving time and the like used for the judgment (S105). Note that, if the degree of wear is received together with the input of the completion of the maintenance work in S104, the maintenance judgment unit 23 can change the driving time judgment threshold and the like.

[0050] As described above, in the management system 100, the electronic device 10 can transmit operating time information of the agricultural machine A to the server device 20. This allows the server device 20 to collect the operating time of the agricultural machine A. The server device 20 then determines whether or not maintenance work is required based on the operating time. If maintenance work is required, the server device 20 can notify the maintenance information. In this way, the management system 100 can manage whether or not maintenance work is required for the agricultural machine A based on the operating time information, and can notify the fact that maintenance work is required.

[0051] The server device 20 acquires the degree of wear of the agricultural machine A confirmed by the maintenance work. When the acquired degree of wear is high, the maintenance determination unit 23 reduces the driving time determination threshold value compared to when the degree of wear is low. In this case, the server device 20 can more appropriately determine whether or not maintenance work is necessary using the driving time information according to the actual degree of wear.

[0052] The time measurement unit 11 of the electronic device 10 measures the operation time of each of the multiple elements of the agricultural machine A. The maintenance determination unit 23 determines whether or not maintenance work is required for each element of the agricultural machine A. In this case, the management system 100 can determine whether or not each element of the agricultural machine A requires maintenance work.

[0053] Furthermore, in the management system 100, the electronic device 10 can transmit vibration information of the agricultural machine A to the server device 20. This enables the server device 20 to collect the vibration information of the agricultural machine A. The server device 20 then determines whether or not maintenance work is required based on the vibration information. When maintenance work is required, the server device 20 can notify the maintenance information. In this way, the management system 100 can manage whether or not maintenance work is required for the agricultural machine A based on the vibration information, and can notify the fact that maintenance work is required. This enables the management system 100 to determine whether or not maintenance work is required depending on the usage status of each agricultural machine A.

[0054] The server device 20 acquires the degree of wear of the agricultural machine A confirmed by the maintenance work. When the acquired degree of wear is high, the maintenance determination unit 23 determines that maintenance work is necessary sooner than when the degree of wear is low, or reduces at least one of the effective value threshold, the integrated time threshold, and the number threshold. In this case, the server device 20 can more appropriately determine whether or not maintenance work is necessary using the vibration information according to the actual degree of wear.

[0055] The electronic device 10 is provided in the agricultural machine A. The electronic device 10 can transmit operating time information of the agricultural machine A to the server device 20. This allows the server device 20 to determine whether or not maintenance work is required for the agricultural machine A, based on the operating time information received from the electronic device 10. In this way, by using the electronic device 10 capable of transmitting operating time information, it is possible to easily manage whether or not maintenance work is required for the agricultural machine A.

[0056] Furthermore, the electronic device 10 can transmit vibration information of the agricultural machine A to the server device 20. This enables the server device 20 to determine whether or not maintenance work on the agricultural machine A is required, based on the vibration information received from the electronic device 10. In this way, by using the electronic device 10 capable of transmitting vibration information, it is possible to easily manage whether or not maintenance work on the agricultural machine A is required.

[0057] According to the above-mentioned management system 100, the implementation of maintenance work, which was conventionally performed at the discretion of the user of the agricultural machine A or a maintenance contractor, can be promoted by, for example, the manufacturer of the agricultural machine A that provides the management system 100. The time until a breakdown occurs in the agricultural machine A differs depending on the environment and conditions in which it is used. For example, if there are differences in the traveling speed of the agricultural machine A during operation, the magnitude of the impact it receives from the road surface, the magnitude of the load, etc., the items that require maintenance will differ even for agricultural machines A that have been used for the same amount of time. Therefore, the management system 100 acquires the operating time and vibration information of each element of the agricultural machine A. In this way, the management system 100 can promote maintenance work according to the individual usage conditions of the agricultural machine A.

[0058] Furthermore, in the management system 100, the server device 20 can collect operation time information and vibration information from the agricultural machine A. This allows the manufacturer of the agricultural machine A to understand how the agricultural machine A is used (the season in which it is used, the time period, the annual hours of use, the vibration, etc.). This allows the manufacturer to use this information as marketing data or as a basis for the product lifespan, and can utilize this information, for example, in the design of the next and subsequent agricultural machines A.
