[First Embodiment]
FIG. 1 shows an overall view of an information collection system for a work machine.
As shown in FIG. 1, a work machine information collection system 1 is a system that collects data (signals) of a work machine 2 such as an agricultural machine or a construction machine using a data collection device 3 or the like. The data collection device 3 is detachably connected to an in-vehicle network N1 provided in the work machine 2 by a connector or the like, and acquires data flowing through the in-vehicle network N1. The in-vehicle network N1 is a controller area network (CAN), a local interconnect network (LIN), FlexRay, etc., and connects various electronic devices (electrical components) 7 mounted on the work machine 2 to each other. Accordingly, various data output from the electronic device can be transmitted and received. Hereinafter, for convenience of explanation, the value (eigenvalue) of data flowing through the in-vehicle network N1 is referred to as a parameter or parameter value. The electronic device (electrical component) 7 is a sensor, a switch, a CPU, an MPU, or the like, but may be any device as long as it is mounted on the work machine 2.

  The data collection device 3 includes a communication unit (input / output unit) 5 and a control unit 6. The communication unit 5 performs wireless communication with the outside, and performs wireless communication based on Wi-Fi (registered trademark) conforming to the IEEE 802.11 series which is a communication standard. Specifically, the communication unit 5 converts the data received from the outside into the communication method of the data collection device 3 and outputs the data to the control unit 6, or converts the data transmitted from the control unit 6 to the IEEE 802.11 series communication method. Change and output to the outside. That is, the communication unit 5 outputs data (signal) received from the outside to the control unit 6 or transmits data (signal) output from the control unit 6 to the outside.

The control unit 6 is composed of a CPU and the like, and performs various processes related to data output to the in-vehicle network N1. For example, the control unit 6 acquires a parameter (parameter value) output to the in-vehicle network N1 in a group unit (a unit in which a plurality of parameters are collectively) or an individual unit.
<Acquisition of parameter group (PG) and PG unit parameters>
Hereinafter, acquisition of parameters (data) by the control unit 6 will be described.

As shown in FIG. 1, the control unit 6 includes a definition storage unit 10. The definition storage unit 10 is composed of a nonvolatile memory or the like, and stores information related to parameter acquisition and storage.
Specifically, as shown in FIG. 2, the definition storage unit 10 stores parameter groups (data groups). This parameter group is defined by associating a parameter collected by the data collection device 3 with a group to which the parameter belongs. A group is a unit that makes it easy to handle each parameter when the parameters are grouped. Parameters with similar parameters are set as the same group, or related parameters are set as the same group. Is done. The relationship between the group and the parameters belonging to the group is set by a manufacturer or the like that manufactures the work machine 2.

Specifically, the parameter group is data defining a group name, communication speed, data size, parameter group first identification information (PGN), parameter names of parameters belonging to the group, and the like. Name, communication speed, data size, first identification information, and parameter names of parameters belonging to the group are set.
In this way, by referring to the parameter group, it is possible to determine which group the parameter belongs to. For example, as shown in FIG. 2, a group having the group name “engine” belongs to a parameter indicating “error presence / absence”, a parameter indicating “engine speed”, and a parameter indicating “water temperature”. As such, they can be identified by PGN (eg, 642239).

The process of acquiring parameters (parameter values) in units of groups is performed by a first acquisition unit 11 provided in the control unit 6 as shown in FIG. The first acquisition unit 11 includes a program stored in the control unit 6.
Under the situation where the work machine 2 is operating, frames having parameters that flow through the in-vehicle network N1 (frames preset in the in-vehicle network) are sequentially input to the data collection device 3 by broadcast communication. This frame includes a plurality of parameters belonging to a predetermined group and also includes first identification information (PGN) for identifying the group.

  The first acquisition unit 11 monitors the PGN included in the frame when the frame is input to the data collection device 3. Here, when a frame including the PGN defined by the parameter group stored in the definition storage unit 10 is input to the data collection device 3, the first acquisition unit 11 acquires (receives) the frame. That is, when the PGN included in the frame matches the PGN of the parameter group, the first acquisition unit 11 receives the frame.

For example, it is assumed that three frames are input to the data collection device 3. At this time, when the PGN included in each of the first frame (first frame) and the second frame (second frame) is not set in the parameter group stored in the definition storage unit 10 The first acquisition unit 11 does not receive the first frame and the second frame. On the other hand, when the PGN included in the third frame (third frame) is set in the parameter group, the first acquisition unit 11 receives the third frame.

FIG. 3 illustrates a group acquisition table of parameters of “engine group” acquired by the first acquisition unit 11 when the PGN of the third frame is “642239”, for example. In the group acquisition table when the third frame is acquired, the acquired parameters (error presence / absence, engine speed, water temperature) are associated with the PGN indicating the group. Thus, the first acquisition unit 11 can acquire the parameters belonging to the group indicated in the parameter group in units of groups.
<Storing parameters in PG units>
As shown in FIG. 1, the data collection device 3 includes an information storage unit 12, and parameters acquired in units of groups are stored in the information storage unit 12. The process of storing parameters in the information storage unit 12 is performed based on predetermined storage conditions.

As shown in FIG. 4, in addition to the parameter group described above, the definition storage unit 10 includes a plurality of parameters acquired in units of groups, that is, a parameter group (group acquisition) in which parameters belonging to a predetermined group are combined into one. A storage condition (group storage condition) for storing the table is stored.
The group storage conditions indicate the current storage conditions that indicate the conditions for temporarily storing the acquired parameter group (group acquisition table) and the conditions for long-term storage of the acquired parameter group (group acquisition table). Log storage conditions (history storage conditions).

Specifically, the information storage unit 12 includes a RAM 12a configured with a volatile memory and an EEPROM 12b configured with a nonvolatile memory. The current storage condition is a condition for storing the parameter group in the RAM 12a, and the log storage condition is a condition for storing the parameter group in the EEPROM 12b.
The current storage condition is a condition suitable for temporarily storing the latest parameter group (storing in the RAM 12a). As the current storage condition, “every received n times”, “at the time of a specific par change”, Three conditions “when the PG unit changes” are prepared.

  Here, “every reception n times” refers to the parameter group (group acquisition table) acquired by the first acquisition unit 11 every time the same parameter group (group acquisition table with the same PGN) is received (acquired) n times. It indicates that the data is stored in the RAM 12a. In this case, the first acquisition unit 11 counts the number of acquisitions (reception times) of acquisition (reception) of a predetermined parameter group (group acquisition table having the same PGN), and the parameter group whose acquisition number is nth. Only in the RAM 12a. The number of acquisitions (number of receptions) is reset every n times (returned to the initial value). Note that when the number of acquisition times is a multiple of n, the first acquisition unit 11 may store the parameter group in the RAM 12a.

  “When the specific par changes” indicates that the parameter group is stored in the RAM 12a only when the parameter (target parameter) set in advance when the parameter group (group acquisition table) is acquired is changed. . In this case, for example, when the parameter “presence / absence of error” is the target parameter, the first acquisition unit 11 determines whether or not the parameter indicating “presence / absence of error” has changed from the previous acquisition. When the parameter indicating “error presence / absence” has changed, the first acquisition unit 11 determines that all parameters of the group to which the parameter “error presence / absence” belongs (for example, error presence / absence, engine rotation) (Number, water temperature) are stored in the RAM 12a.

  “At PG unit change” means saving a parameter group (group acquisition table) when any one of the parameters in the parameter group has changed from the previous acquisition when the parameter group is acquired. Show. In this case, the 1st acquisition part 11 judges whether any parameters, such as the presence or absence of an error, engine speed, and water temperature, are changing, for example. When any one of the parameters of the presence / absence of the error, the engine speed, and the water temperature is changed, the first acquisition unit 11 stores these parameter groups (group acquisition table).

As described above, after acquiring the parameter group, the first acquisition unit 11 satisfies any one of the storage conditions “every received n times”, “when the specific par is changed”, and “when the PG unit is changed”. In addition, the acquired parameter group (group acquisition table) is stored in the RAM 12a, and any one of the conditions “every received n times”, “at the time of specific par change”, and “at the time of PG unit change” is defined in the definition storage unit 10. The parameter group (group acquisition table) may be stored by the first acquisition unit 11 in advance. Further, the current storage condition is not limited to the above-described example.

The log storage conditions are suitable for storing the parameter group for a long time (stored in the EEPROM 12b). As the log storage conditions, "every current value storage every n times", "every t hours", and "KeyOff" Three conditions are prepared.
“Every n times the current value is stored” means that each time a parameter group (group acquisition table) is stored n times based on the current storage conditions (the number of times the group acquisition table having the same PGN is stored in the RAM 12a is n times). ) Shows that the parameter group (group acquisition table) is stored in the EEPROM 12b. In this case, the first acquisition unit 11 counts the number of times of saving in the RAM 12a in a predetermined parameter group (group acquisition table with the same PGN), and acquires the parameter group (group acquisition) when the number of times of storage becomes n. Table) is read from the RAM 12a and stored in the EEPROM 12b. When the number of times the predetermined parameter group is stored in the RAM 12a is nth, the number of times stored is reset (returned to the initial value). Note that when the number of times of saving becomes a multiple of n, the first acquisition unit 11 may save the parameter group in the EEPROM 12b.

“Every t time” indicates that the parameter group (group acquisition table) acquired by the first acquisition unit 11 is stored in the EEPROM 12b every time t time elapses. In this case, the first acquisition unit 11 measures the time using a counter or the like, and saves the parameter group every time t has elapsed since the saving to the EEPROM 12b.
“At key-off time” means a parameter group (group) acquired by the first acquisition unit 11 when an engine key (for example, an ignition key) that drives a drive source (such as an engine) mounted on the work machine 2 is turned off. (Acquisition table) is stored in the EEPROM 12b. In this case, the first acquisition unit 11 monitors the ignition key at the time of parameter collection. When the ignition key is ON, the acquired parameter group (group acquisition table) is not saved, and the ignition key is turned off. When this happens, the parameter group is stored in the EEPROM 12b.

  As described above, the first acquisition unit 11 acquires the parameter group and then satisfies any one of the storage conditions “every current value storage n times”, “every t hours”, and “at the time of Key Off”. The acquired parameter group (group acquisition table) is stored in the EEPROM 12b, but any one of the conditions “every current value storage n times”, “every t hours”, and “at the time of Key Off” is stored in the definition storage unit 10. The parameter group (group acquisition table) may be stored by the first acquisition unit 11 in advance. Further, the log storage condition is not limited to the above-described example.

As described above, the group storage conditions (for example, the current storage conditions and the log storage conditions) for storing the parameter group in the information storage unit 12 (for example, the RAM 12a and the EEPROM 12b) are stored in the definition storage unit 10, and the first acquisition unit 11 Since the parameter group (group acquisition table) is stored in the information storage unit 12 based on the group storage conditions, it is possible to avoid storing a useless parameter group and effectively use the information storage unit 12. .
<Acquisition of individual unit parameters (Par)>
As described above, the data collection device 3 acquires parameters (parameter values) in units of groups. In addition, the data collection device 3 also acquires parameters in individual units.

The process of acquiring individual unit parameters is performed by the second acquisition unit 13 provided in the control unit 6. The second acquisition unit 13 includes a program stored in the control unit 6.
As shown in FIG. 5, when the first acquisition unit 11 acquires parameters in units of groups, the second acquisition unit 13 divides the acquired parameter group into individual parameters, and sets parameters for each parameter. Obtained separately from the parameter group. For example, when the first acquisition unit 11 acquires a frame including a parameter belonging to an engine group, the second acquisition unit 13 converts the data stored in the frame to a parameter indicating “error presence / absence”, “engine speed” Are obtained separately from the above-described parameter group. That is, as shown in FIG. 5, the second acquisition unit 13 performs an error acquisition table for parameters indicating “error presence / absence”, an engine acquisition table for parameters indicating “engine speed”, and a water temperature for parameters indicating “water temperature”. Create an acquisition table.

  In the error acquisition table, the second acquisition unit 13 associates a parameter indicating the presence / absence of an error with second identification information (referred to as ParN) for identifying that the parameter is “presence / absence of error”. Similarly, in the engine acquisition table, the second acquisition unit 13 associates a parameter indicating the engine speed with ParN for identifying that the parameter is “engine speed”, and also in the water temperature acquisition table, And ParN for identifying that the parameter is “water temperature”.

  That is, the second acquisition unit 13 continuously acquires a parameter (error acquisition table) indicating “error presence / absence” or continuously acquires a parameter (engine acquisition table) indicating “engine speed”. Or a parameter indicating the water temperature (water temperature acquisition table) can be acquired continuously. In summary, the second acquisition unit 13 can acquire individual parameters by dividing the parameters acquired by the first acquisition unit 11 in units of groups into individual unit parameters.

Hereinafter, the individual unit parameter will be referred to as an individual parameter, the parameter indicating “error presence / absence” as the first parameter, the parameter indicating “engine speed” as the second parameter, and the parameter indicating the water temperature as the third parameter. Continue the explanation. Further, the error acquisition table, engine acquisition table, and water temperature acquisition table will be described as individual acquisition tables.
<About saving parameters of Par>
The individual parameters are stored in the information storage unit 12. The process of storing the individual parameters in the information storage unit 12 is also performed based on a predetermined storage condition.

As shown in FIG. 6, the definition storage unit 10 stores storage conditions (individual storage conditions) for storing individual parameters in addition to the parameter groups and group storage conditions described above.
As shown in FIG. 6, the current storage condition indicating the condition for temporarily storing the acquired individual parameter (individual acquisition table) and the acquired individual parameter (individual acquisition table) as long-term There is a log storage condition (history storage condition) indicating a condition for storage. In the following description of the individual storage condition, an “engine acquisition table” that is one of the individual acquisition tables will be described as an example.

The current storage conditions are conditions suitable for temporarily storing the latest individual parameters (storing in the RAM 12a), and the current storage conditions are “every received n times” and “when a specific par changes”. Two conditions are prepared.
Here, “every reception n times” means that each time the same individual parameter (engine acquisition table) is received (acquired) n times, the individual parameter (engine acquisition table) acquired by the second acquisition unit 13 is stored in the RAM 12a. It shows that

  In this case, the second acquisition unit 13 counts the number of acquisitions (reception times) at which the predetermined individual parameter (engine acquisition table) is acquired (received), and the individual acquired when the acquisition number reaches the nth time. Only the parameters (engine acquisition table) are stored in the RAM 12a. The number of acquisitions (number of receptions) is reset every n times (returned to the initial value). When the number of acquisition times is a multiple of n, the second acquisition unit 13 may store the individual parameter (engine acquisition table) in the RAM 12a.

“When the specific par is changed” indicates that the individual parameter (engine acquisition table) is stored in the RAM 12a only when the parameter (target parameter) set in advance when the individual parameter is acquired is changed. . In this case, for example, when the second parameter of “engine speed” is set as the target parameter, the second acquisition unit 13 determines whether or not the second parameter has changed from the previous acquisition. When the second parameter has changed, the second acquisition unit 13 displays the second parameter, that is, the engine acquisition table in the RAM 12a.
Save to.

As described above, after the second acquisition unit 13 acquires the individual parameter (engine acquisition table), when any one of the storage conditions “every reception n times” or “when the specific par changes” is satisfied, The acquired individual parameter (engine acquisition table) is stored in the RAM 12a. However, any one condition of “every n receptions” or “when the specific par is changed” is stored in the definition storage unit 10, and the second Saving of the individual parameters (engine acquisition table) by the acquisition unit 13 may be executed. Further, the current storage condition is not limited to the above-described example. Also,
The log storage conditions are suitable for storing individual parameters for a long time (stored in the EEPROM 12b). As the log storage conditions, "every current value storage every n times", "every t hours", and "Key Off" Three conditions are prepared.

  “Current value storage every n times” means that each time an individual parameter is stored n times (every number of times the engine acquisition table is stored in the RAM 12a becomes n times) based on the current storage condition, the individual parameter (engine acquisition) Table) is stored in the EEPROM 12b. In this case, the second acquisition unit 13 counts the number of times the predetermined individual parameter (engine acquisition table) is stored in the RAM 12a, and only the individual parameter (engine acquisition table) acquired when the number of storage times reaches n. Is read from the RAM 12a and stored in the EEPROM 12b. When the number of times of storage is n, the number of times of storage is reset (returned to the initial value). Note that when the number of times of storage becomes a multiple of n, the second acquisition unit 13 may store the individual parameters (engine acquisition table) in the EEPROM 12b.

  “Every t time” indicates that the individual parameter (engine acquisition table) acquired by the second acquisition unit 13 is stored in the EEPROM 12b every time t time elapses. In this case, the second acquisition unit 13 measures the time using a counter or the like, and stores the individual parameter (engine acquisition table) every time t has elapsed since the end of the storage in the EEPROM 12b.

  “When Key Off” means that the individual parameter acquired by the second acquisition unit 13 when the engine key (for example, the ignition key) for driving the drive source (engine or the like) mounted on the work implement 2 is turned off is the EEPROM 12b. To save. In this case, the second acquisition unit 13 monitors the ignition key at the time of parameter collection. When the ignition key is ON, the acquired individual parameter (engine acquisition table) is not stored, and the ignition key is turned off. When this happens, the individual parameters are stored in the EEPROM 12b.

  As described above, after the second acquisition unit 13 acquires the individual parameter (engine acquisition table), the storage condition of “every current value storage every n times”, “every t hours”, or “at the time of Key Off” is set. When satisfied, the acquired individual parameter (engine acquisition table) was stored in the EEPROM 12b. However, any one of the conditions “every current value storage every n times”, “every t hours”, and “at the time of Key Off” is set. You may preserve | save in the definition memory | storage part 10, and may preserve | save the individual parameter (engine acquisition table) by the 2nd acquisition part 13. FIG. Further, the log storage condition is not limited to the above-described example.

In the above description of the individual storage conditions, the “engine acquisition table” has been described as an example. However, the “error acquisition table” and the “water temperature acquisition table” are also stored based on the individual storage conditions.
As described above, the individual storage conditions (for example, the current storage conditions and the log storage conditions) for storing the individual parameters in the information storage unit 12 (for example, the RAM 12a and the EEPROM 12b) are stored, and the individual parameters acquired by the second acquisition unit 13 are stored. Since the (individual acquisition table) is stored in the information storage unit 12 based on the individual storage conditions, it is possible to avoid saving useless individual parameters (individual acquisition table) and to effectively use the information storage unit 12 Can do.

<Part 1 of the definition file (individual storage conditions)>
The individual storage conditions described above are shown in a definition file indicating the relationship between information related to the group acquisition table and information related to the individual acquisition table. This definition file is predetermined for each model of the work machine 2 and is stored in the definition storage unit 10. FIG. 7 shows an example of the definition file.

As shown in FIG. 7, the definition file includes “PGN” that is the first identification information of the parameter group, “ParN” that is the second identification information of the individual parameter, and individual storage conditions (for example, current storage conditions, log Storage condition) and related data.
When storing the acquired individual parameter, the second acquisition unit 13 first refers to the ParN corresponding to the individual parameter to be stored, the PGN of the group to which the individual parameter belongs, and the definition file, and Extract individual storage conditions from the definition file. For example, as shown in FIG. 7, when ParN of the second parameter (parameter indicating the engine speed) is “12” and the PGN to which the second parameter belongs is “642239”, the second acquisition unit 13 Uses “every received n times” corresponding to these ParN and PGN as current storage conditions and “every t time” as log storage conditions. Then, the second acquisition unit 13 stores the second parameter in the RAM 12a every reception n times, and stores the second parameter in the EEPROM 12b every t time.

  That is, the second acquisition unit 13 extracts the individual parameter individual storage conditions based on the first identification information of the group to which the individual parameter belongs, the second identification information of the parameter corresponding to the individual parameter, and the definition file. The individual parameters are stored in the information storage unit 12 based on the extracted individual storage conditions. That is, the second acquisition unit 13 divides the group unit parameters (parameter group) acquired by the first acquisition unit 11 into individual parameters, and among the divided individual parameters, the individual that conforms to the storage conditions defined in the definition file The parameters are to be saved.

<About parameter output (transmission)>
The parameters stored in the RAM 12a and the EEPROM 12b are output to the outside via the communication unit (input / output unit) 5. Specifically, the communication unit (input / output unit) 5 transmits to a mobile terminal 4 constituted by, for example, a smartphone (multifunctional mobile phone) or a tablet PC having a relatively high computing capability. The portable terminal 4 performs wireless communication with the communication unit 5 by Wi-Fi (registered trademark) conforming to the IEEE 802.11 series which is a communication standard. For example, when a parameter is requested from the portable terminal 4, communication is performed. The unit 5 reads the parameter group (group acquisition table) and individual parameters (individual acquisition table) stored in the EEPROM 12 b via the control unit 6, and transmits the read parameters to the mobile terminal 4.

In a state where wireless communication between the mobile terminal 4 and the communication unit 5 is established, the communication unit 5 reads the parameter group (group acquisition table) and the individual parameters (individual acquisition table) stored in the RAM 12a. And sequentially transmitted to the portable terminal 4. That is, the communication unit 5 pushes the parameters stored in the RAM 12a toward the portable terminal 4.
As described above, according to the first acquisition unit 11 and the second acquisition unit 13, parameters belonging to a group can be acquired in units of groups, and individual unit parameters can also be acquired.

  Therefore, by looking at the parameters acquired in units of groups, that is, the group acquisition table, it is possible to immediately grasp what the parameters at a predetermined timing are. For example, since the error presence / absence parameter, the engine speed parameter, and the water temperature parameter are grouped and acquired, the group acquisition table shows the values of the engine speed and water temperature when the error occurred. Can quickly grasp.

  On the other hand, by looking at individual unit parameters, that is, individual acquisition tables, it is possible to immediately grasp changes, transitions, etc. of predetermined parameters. For example, since the engine speed parameter is also acquired individually, the engine acquisition table shows how the engine speed has changed compared to the previous time, or how the engine speed during a predetermined period has changed. You can grasp quickly.

Moreover, according to the 1st acquisition part 11 and the 2nd acquisition part 13, the parameter of the acquired group unit and the parameter of an individual unit can also be preserve | saved in RAM12a or EEPROM12b based on a preservation | save condition. Therefore, although a large number of parameters are output to the in-vehicle network N1 in a short period of time, necessary parameters can be acquired at necessary intervals depending on the storage conditions. For example, information about an error is necessary when an error occurs, and it is not necessary to shorten the storage interval compared to the engine speed. Conversely, the engine speed is necessary when the work machine 2 is in operation. There is therefore a need to save more frequently than information about errors.

  As described above, the parameters stored in the information storage unit 12 (for example, the RAM 12a and the EEPROM 12b) are transmitted to the outside of the portable terminal 4 or the like via the communication unit 5, so that the parameters of the work machine 2 are acquired by the portable terminal 4. be able to. Then, by organizing the acquired parameters with the portable terminal 4 or the like, it is possible to analyze the work situation when the work machine 2 performs work. Moreover, the parameter when working with the work machine 2 can be acquired on the mobile terminal 4 side as operation information.

<Calculation conditions>
In the above-described embodiment, the individual parameter (individual acquisition table) is acquired and stored by the second acquisition unit 13, but before the individual parameter is stored in the information storage unit 12 (RAM 12a, EEPROM 12b), the individual parameter is stored. It is preferable to store the calculation result in the information storage unit 12. Next, a case where the individual parameters are calculated and stored (modified example) will be described.

The calculation of the individual parameters is performed by the calculation unit 14 provided in the control unit 6. The calculation unit 14 is composed of a program stored in the control unit 6. The calculation unit 14 calculates individual parameters based on predetermined calculation conditions.
As calculation conditions, four conditions of “accumulation”, “count”, “statistics”, and “frequency” are prepared. “Cumulative” indicates that the time when the same individual parameter (individual acquisition table with the same ParN) is a value (specified value) designated in advance within a predetermined time is calculated. The specified value is predetermined for each individual parameter. For example, it is assumed that “800 rpm” is set as the designated value of the engine speed. In this case, the calculation unit 14 has the second parameter set to “" within a predetermined period of time in a situation where the second acquisition unit 13 continuously acquires a parameter indicating the engine speed (second parameter). The time of “800 rpm” is obtained.

  “Counting” indicates that the number of times that the same individual parameter (individual acquisition table with the same ParN) is within a predetermined range (specified range) within a predetermined time is calculated. For example, the designated range of the engine speed is a range of “600 rpm to 800 rpm” (first designated range), a range of “801 to 1000 rpm” (second designated range), and a range of “1001 to 1500 rpm” (third designated range). ), A range of “1501 rpm or more” (fourth specified range) is set.

In this case, the calculation unit 14 counts the number of times the second acquisition unit 13 has entered the first specified range within a predetermined time under the condition where the second acquisition unit 13 continuously acquires the second parameter (engine speed), the second specification. The number of times of entering the range, the number of times of entering the third designated range, and the number of times of entering the fourth designated range are obtained.
“Statistics” indicates that the average value, maximum value, and minimum value of the same individual parameter (individual acquisition table with the same ParN) are calculated. For example, the calculation unit 14 is configured such that the average value, the maximum value, and the minimum value of the engine speed acquired within a predetermined time in a situation where the second acquisition unit 13 continuously acquires the second parameter (engine speed). Find the value.

“Frequency” indicates that the time when the same individual parameter (individual acquisition table with the same ParN) is in a predesignated range (designated range) is calculated. For example, it is assumed that the first designated range, the second designated range, the third designated range, and the fourth designated range are set as the designated range of the engine speed, as in “counting”. In this case, the calculation unit 14 is configured such that the second parameter is the first specified range in a situation where the second acquisition unit 13 continuously acquires a parameter indicating the engine speed (second parameter). The time in the second designated range, the time in the third designated range, and the time in the fourth designated range are obtained. It should be noted that the end of the calculation is preferably executed when the second parameter falls outside a predetermined designated range. For example, in a situation where the calculation unit 14 uses the second parameter to obtain the time “801 to 1000 rpm” (second designated range), the second parameter (for example, out of the second designated range (for example, , 680 rpm) when the second acquisition unit 13 acquires, the calculation of the time within the second specified range is terminated.

The individual parameters calculated according to the calculation conditions of “cumulative”, “count”, “statistic”, and “frequency” are sequentially stored in the RAM 12a after the calculation is completed.
<About definition file 2 (calculation conditions)>
The calculation conditions described above are also shown in the definition file. FIG. 8 shows an example of a definition file having individual storage conditions and calculation conditions.

As shown in FIG. 8, the definition file includes data in which PGN, ParN, individual storage conditions, and calculation conditions are associated with each other.
When calculating the acquired individual parameter, the second acquiring unit 13 first refers to the ParN corresponding to the calculated individual parameter, the PGN of the group to which the individual parameter belongs, and the definition file, and Extract current storage conditions and calculation conditions from the definition file. For example, as shown in FIG. 8, when the ParN of the second parameter (parameter indicating the engine speed) is “12” and the PGN to which the second parameter belongs is “642239”, the second acquisition unit 13 Uses “every n receptions” corresponding to these ParN and PGN as current storage conditions and “frequency” as a calculation condition. The second acquisition unit 13 acquires the second parameter (engine speed) every n reception times, and the calculation unit 14 uses the second parameter acquired every n receptions and the “frequency” calculation condition. Thus, the frequency of the engine speed, that is, the time during which the engine speed is in the first designated range to the fourth designated range is calculated in each designated range. When the calculation is completed, the second acquisition unit 13 stores the calculation result in the EEPROM 12b.

The second acquisition unit 13 also extracts log storage conditions with reference to ParN, PGN, and the definition file, and stores the calculation result in the EEPROM 12b based on the log storage conditions.
As described above, according to the calculation unit 14 and the like, the calculation unit 14 calculates individual parameters based on the calculation conditions specified in the definition file, and stores the calculation results of the individual parameters calculated by the calculation unit 14 in the RAM 12a. At the same time, it can be stored in the EEPROM 12b.

  According to the data collection device 3 of the present invention, data (parameters) flowing through the in-vehicle network N1 of the work machine 2 can be collected in units of groups or individual units, and necessary data can be obtained depending on storage conditions and calculation conditions. Can be stored compactly. For example, when the data collection device 3 is attached to a tractor, a combiner, or a rice transplanter, operation data relating to farm work can be easily obtained.

  For example, when a cultivator is connected to the rear part of the tractor as a working device and the tractor is operated, parameters (data) such as the rotational speed of the rotary, the load of the rotary, the engine rotational speed, the vehicle speed, and the tilling depth are stored in the in-vehicle network N1. Is output. The first acquisition unit 11 and the second acquisition unit 13 can acquire parameters (data) such as the rotational speed of the rotary, the load of the rotary, the engine rotational speed, the vehicle speed, and the tilling depth. The rotational speed of the rotary, the load of the rotary, the engine speed, the vehicle speed, the tilling depth, and the like are detected by an electronic device (electrical component) 7 such as a sensor attached to the tractor or the tilling device.

  Alternatively, when the working device connected to the tractor is a fertilizer spraying device, a pesticide spraying device, or a seeding spraying device, the first acquisition unit 11 and the second acquisition unit 13 are configured such that the vehicle speed, the engine speed, the spraying amount (fertilizer spraying). Parameters (data) such as amount, pesticide application amount, and sowing application amount) can be acquired. The application amount (fertilizer application amount, pesticide application amount, sowing application amount) is also detected by an electronic device (electrical component) 7 attached to the tractor, the fertilizer application device, the agrochemical application device, and the seed application device.

When the working device is a harvesting device, data (parameters) such as the vehicle speed, the engine speed, and the harvest amount are output to the in-vehicle network N1, and the vehicle speed, the engine speed, and the harvest amount can be acquired. The amount of harvest is also detected by an electronic device (electrical component) 7 attached to the tractor or harvesting device.
In this way, by attaching the data collection device 3 to an agricultural machine such as a tractor, the rotational speed of the rotary, the load of the rotary, the engine speed, the vehicle speed, the tilling depth, the spraying amount, and the harvesting amount can be acquired as parameters. it can.

In the data collection device 3 described above, a definition file having a parameter group, a storage condition, a calculation condition, and the like is stored in the definition storage unit 10 in order to collect data (parameters) of the work machine 2. The file is written in the definition storage unit 10 by the manufacturer when the work machine 2 is manufactured.
FIG. 9 shows an overall view of a system for writing a condition to the data collection device 3, that is, a system for writing a definition file. A configuration different from the above-described embodiment will be described. Note that the data collection device 3 is the same as that in the above-described embodiment, and thus the description thereof is omitted.

  As shown in FIG. 9, the writing system 20 includes a computer 21 for writing conditions in the data collection device 3. The computer 21 has a definition file corresponding to the model of the work machine 2, and writes a definition file corresponding to the model of the work machine 2 to the data collection device 3. For example, the computer 21 writes a definition file including a storage condition in the data collection device 3 corresponding to the model of the work machine, or writes a definition file including a parameter group corresponding to the model of the work machine 2. Alternatively, the computer 21 writes a definition file including calculation conditions in the data collection device 3 corresponding to the model of the work machine 2. In addition, although a model is the language which shows the kind of machine, in this embodiment, the case where a case where a model differs differs is also included.

FIG. 10 shows a plurality of definition files divided into blocks.
As shown in FIG. 10, the definition file (condition) includes PGN blocks A (A1 to A4) having different parameter groups (relationships between groups and parameters belonging to the group), ParN (second identification information of parameters), and A plurality of calculation blocks B (B1 to B4) having different relationships with calculation conditions, and a plurality of storage blocks C (C1 to C4) having different relationships between ParN (second identification information of parameters) and storage conditions, respectively By combining, it is constructed as a file corresponding to the model of the work machine 2.

  The computer 21 has a plurality of definition files composed of combinations of PGN block A, calculation block B, and calculation block C prepared in advance. When the model of the work machine 2 (the model of the work machine on which the data collection device 3 is mounted) is selected on the monitor of the computer 21, the computer 21 reads the PGN block A and the calculation block corresponding to the selected model. A definition file having B and calculation block C is extracted, and the extracted definition file is written in the data collection device 3 connected to the computer 21.

  For example, when the work machine 2 is a small tractor, the computer 21 is configured into a first PGN block A1, a third calculation block B3, and a second storage block C2 from a plurality of definition files. The defined definition file (arrow Q1) is extracted, and the definition file is written in the data collection device 3 attached to the small tractor 2. In addition, when the work implement 2 is a large tractor, the computer 21 defines a definition file (arrow Q2) composed of a first PGN block A1, a first calculation block B1, and a second storage block C3. And the definition file is written into the data collection device 3 attached to the large tractor 2. When the work machine 2 is a combine, the computer 21 defines a definition file configured by a third PGN block A3, a second calculation block B2, and a third storage block C3 from among a plurality of definition files. (Arrow Q3) is extracted and the definition file is written in the data collection device 3 attached to the combine.

As the work machine 2, there are a tractor, a combiner, a rice transplanter, and the like, but even if the tractor is the same as the type of the work machine 2, as described above, the small tractor and the large tractor are connected to the in-vehicle network N1. Since the output conditions of the parameters to be output (for example, the output interval, the number of bits of the parameters, etc.) are different, writing the definition file with different calculation conditions for each model in the data collection device 3 allows the data (parameters) after calculation to be calculated. It becomes possible to make it the same form (form). In addition, even with the same agricultural machine, the output conditions of the parameters output to the in-vehicle network N1 may be different in the tractor, combine, and rice transplanter, and by changing the definition file accordingly, Numerical values of data (data after calculation) collected by the data collection device 3 can be unified among different models.
[Second Embodiment]
The second embodiment shows a modification of the writing system and the data collection device 3 of the writing system. A configuration different from the first embodiment will be described.

As shown in FIG. 11, the writing system 20 includes a data collection device 3 and a computer 21. First, the data collection device 3 will be described.
The data collection device 3 acquires various data output from an electronic device (electrical component) mounted on the work machine 2. As in the first embodiment, the electronic device (electrical component) is a sensor, a switch, a CPU, an MPU, or the like, but may be any device as long as it is mounted on the work machine 2.

  In the first embodiment, the data collection device 3 acquires data output to the in-vehicle network via the in-vehicle network. However, the data collection device 3 in the second embodiment uses the in-vehicle network. The data may be acquired via the electronic device, or the data output from the electronic device may be directly acquired from the electronic device. In other words, the data collection device 3 of this embodiment can be connected to the in-vehicle network of the work machine 2 or an electronic device.

  In the first embodiment, data (parameters) is acquired in units of data groups (parameter groups), and a data group (parameters) acquired in units of groups is divided into individual data (individual parameters) (first method) In the second embodiment, data may be collected by the first method as shown in the first embodiment. However, in the second method, the data is collected by the first method. There is no limitation, and a method of acquiring data only by group unit acquisition or a method of acquiring data only by individual unit may be used.

As shown in FIG. 11, the data collection device 3 includes a communication unit (input / output unit) 5, a control unit 6, a definition storage unit 10, and an information storage unit 12.
The communication unit 5 performs wireless communication with the outside, and performs wireless communication based on Wi-Fi (registered trademark) conforming to the IEEE 802.11 series which is a communication standard. Specifically, the communication unit 5 converts the data received from the outside into the communication method of the data collection device 3 and outputs the data to the control unit 6, or converts the data transmitted from the control unit 6 to the IEEE 802.11 series communication method. Change and output to the outside. That is, the communication unit 5 outputs data (signal) received from the outside to the control unit 6 or transmits data (signal) output from the control unit 6 to the outside.

The definition storage unit 10 and the information storage unit 12 are configured by a nonvolatile memory, for example, an EEPROM. The definition storage unit 10 stores setting conditions regarding data collection, and the information storage unit 12 stores acquired data, calculation results, and the like.
The control unit 6 includes a CPU and the like, and performs various processes related to data output to the electronic device or the in-vehicle network. When the data input to the data collection device 3 is data to be collected, the control unit 6 accepts the input data and stores it in the information storage unit 12 or uses the acquired data. To perform arithmetic processing. Data storage processing and calculation processing are performed based on setting conditions stored in the definition storage unit 10.

For example, when data such as the presence / absence of an error, the engine speed, and the water temperature are input to the data collection device 3, the control unit 6 indicates the presence / absence of an error, the engine speed, and the water temperature based on the set conditions. 12 to store. Further, the control unit 6 performs a calculation using data such as the presence / absence of an acquired error, engine speed, and water temperature based on the set condition.
When the data transmitted from the outside to the data collection device 3 is rewrite data (for example, a definition file having setting conditions), when the communication unit 5 receives the rewrite data, the control unit 6 The definition file stored in the definition storage unit 10 is rewritten.

Next, the setting conditions will be described in detail.
The setting conditions related to data collection are conditions related to data storage (referred to as storage conditions) and conditions related to data calculation (calculation conditions). The storage conditions and calculation conditions are stored in the definition storage unit 10 as a definition file.
FIG. 12 summarizes examples of setting conditions, that is, storage conditions shown in the definition file and calculation conditions shown in the definition file.

As shown in FIG. 12, in the definition file, four conditions of “every n receptions”, “at the time of change”, “every t hours”, and “at the time of Key Off” are prepared as storage conditions.
Here, “every n receptions” means that each time the control unit 6 (data collection device 3) receives (acquires) data n times, the data acquired by the control unit 6 is stored in the information storage unit 12. Indicates to save. In this case, the control unit 6 counts the number of acquisitions (reception times) at which predetermined data (for example, engine speed) is acquired (received), and the predetermined number acquired when the acquisition number reaches the nth time. Only data (for example, engine speed) is stored in the information storage unit 12. The number of acquisitions (number of receptions) is reset every n times (returned to the initial value). Note that when the number of acquisition times is a multiple of n, the control unit 6 may store the acquired data in the information storage unit 12.

“At the time of change” means that the data is stored in the information storage unit 12 only when the data has changed compared to the previous acquisition. In this case, for example, when the engine speed changes, the control unit 6 stores the engine speed.
“Every t time” means that the data acquired by the control unit 6 (data collection device 3) is stored in the information storage unit 12 every time t time elapses. In this case, the control unit 6 measures the time using a counter or the like, and stores the data every time t has elapsed since the end of the storage in the information storage unit 12.

  “When key is off” is acquired by the control unit 6 (data collection device 3) when an engine key (for example, an ignition key) that drives a drive source (such as an engine) mounted on the work machine 2 is turned off. Data is stored in the information storage unit 12. In this case, the control unit 6 monitors the ignition key at the time of data collection, does not store the acquired data when the ignition key is ON, and stores the data when the ignition key is turned off. Stored in section 12.

Although the four storage conditions “every n receptions”, “at the time of change”, “every t time”, and “at the time of key off” are shown, the storage conditions are not limited to those described above.
In the definition file, four conditions of “cumulative”, “count”, “statistic”, and “frequency” are prepared as calculation conditions. In the description of the calculation conditions, the description of the engine speed data will be made for convenience of explanation.

  “Cumulative” indicates that the time during which predetermined data is a value (specified value) specified in advance within a predetermined time is calculated. The designated value is predetermined for each predetermined data. For example, if “800 rpm” is set as the designated value for the engine speed data, the controller 6 uses the acquired engine speed to set the engine speed to “800 rpm within a predetermined time. ”Is determined.

  “Counting” indicates that the number of times that predetermined data falls within a predetermined range (specified range) within a predetermined time is calculated. For example, the designated range of the engine speed is a range of “600 rpm to 800 rpm” (first designated range), a range of “801 to 1000 rpm” (second designated range), and a range of “1001 to 1500 rpm” (third designated range). ), A range of “1501 rpm or more” (fourth specified range) is set.

In this case, the control unit 6 uses the acquired engine speed, the number of times the engine speed has entered the first specified range within a predetermined time, the number of times the engine has entered the second specified range, and the third specified range. The number of times, the number of times that has become the fourth specified range, is obtained.
“Statistics” indicates that an average value, a maximum value, and a minimum value of predetermined data are calculated. For example, the control unit 6 obtains the average value, the maximum value, and the minimum value of the engine speed acquired within a predetermined time by using the acquired engine speed.

“Frequency” indicates that the time during which predetermined data is in a predesignated range (designated range) is calculated. For example, it is assumed that the first designated range, the second designated range, the third designated range, and the fourth designated range are set as the designated range of the engine speed, as in “counting”. In this case, the control unit 6 uses the acquired engine speed, the time when the engine speed is in the first specified range, the time that is in the second specified range, and the third specified range. And the time within the fourth specified range are obtained. It should be noted that the calculation is preferably terminated when the engine speed is out of a predetermined designated range. For example, in a situation where the control unit 6 obtains a time during which the engine speed is “801 to 1000 rpm” (second designated range), the acquired engine speed is, for example, 680 rpm and the second designation. When out of the range, the calculation of the time within the second specified range is terminated. As described above, the result calculated according to the calculation conditions of “cumulative”, “count”, “statistic”, and “frequency” is stored in the information storage unit 12 after the calculation is completed.

FIG. 13 exemplifies the relationship between the storage conditions and calculation conditions described above and data in the definition file.
Specifically, identification information is set for each piece of data in the definition file, and this identification information is associated with conditions (storage conditions, calculation conditions). As shown in FIG. 13, for example, for the data of “presence / absence of error”, a number “11” indicating that this data is “presence / absence of error” is set as identification information. For the identification information “”, “when changed” is set as the storage condition, and the calculation condition is not set (blank).

In the definition file, for the data of “engine speed”, the number “12” indicating that this data is “engine speed” is set as identification information, and the “engine speed” For the identification information, “every reception n times” is set as the storage condition, and “frequency” is set as the calculation condition.
Further, in the definition file, the number “13” indicating that the data is “water temperature” is set as identification information for the “water temperature” data, and the identification information for “water temperature” is saved. “Every t time” is set as the condition, and “statistics” is set as the calculation condition.

  As described above, in the definition file, a preset storage condition and a preset calculation condition are associated with each piece of data identification information. Therefore, when the data collection device 3, that is, the control unit 6 acquires the data, the data collection device 3 stores or calculates the acquired data based on the storage condition and the calculation condition associated with the data, and stores the data. Saved in the information storage unit 12.

  Now, the relationship between the above-described data identification information, storage conditions, and calculation conditions, that is, the setting conditions are different for each definition file, and as shown in FIG. It is stored in the computer 21 for writing the conditions in the data collection device 3. In other words, the computer 21 has a nonvolatile storage unit 30 that stores a plurality of definition files.

Next, definition files with different setting conditions will be described in detail.
FIG. 14 exemplifies the relationship among data identification information, storage conditions, and calculation conditions in three definition files.
As shown in FIG. 14, the first definition file (first definition file) has a storage condition of “when changed” among a plurality of storage conditions for “error presence / absence” data. Is not set. The first definition file saves “frequency” among a plurality of calculation conditions with “every n receptions” as a save condition among a plurality of save conditions for “engine speed” data. As a condition. Further, the first definition file uses “every t time” as a storage condition among a plurality of storage conditions and “statistics” as a calculation condition among a plurality of calculation conditions for “water temperature” data. . That is, the first definition file is the same as the definition file shown in FIG.

The second definition file (second definition file) has the same calculation conditions as the first definition file, but for “water temperature” data, it is not “every t time” out of a plurality of storage conditions. , “Every n times received” is the storage condition.
The third definition file (third definition file) has the same storage conditions as the first definition file, but for the “engine speed” data, it is not “frequency” among a plurality of calculation conditions. “Statistics” is a calculation condition.

As described above, the storage unit 30 of the computer 21 stores definition files having different combinations of data and setting conditions (storage conditions and calculation conditions).
The computer 21 performs a process of writing a definition file corresponding to the model of the work machine 2 in the data collection device 3 (definition storage unit 10). That is, the storage unit 30 of the computer 21 stores a plurality of definition files having different setting conditions (storage conditions and calculation conditions), and the computer 21 selects the model of the work machine 2 from the plurality of definition files. A process of writing a definition file corresponding to the data collection device 3 is performed.

Next, the computer 21 will be described in detail.
The computer 21 writes a definition file in the data collection device 3 and is composed of, for example, a personal computer. The computer 21 may be configured by a smartphone (multifunctional mobile phone), a tablet, or the like.
The computer 21 and the data collection device 3 can be connected by wire or wirelessly. Specifically, the computer 21 is provided with a communication unit 34 that performs wireless communication. The communication unit 34 performs wireless communication with the communication unit 5 of the data collection device 3. The communication unit 34 performs wireless communication based on Wi-Fi (registered trademark) conforming to the IEEE 802.11 series which is a communication standard. A definition file or the like can be transmitted to the data collection device 3 (communication unit 5). Alternatively, the computer 21 is provided with a communication unit 35 that performs wired communication. The communication unit 35 performs wired data communication with the communication unit 5 of the data collection device 3. The communication unit 35 connects the communication unit 5 and the communication unit 35 with a cable so that a definition file or the like is transferred to the data collection device 3 ( It can be transmitted to the communication unit 5). When the computer 21 and the data collection device 3 are connected by wire, the communication unit 5 (input / output unit) of the data collection device 3 is not only a device that performs wireless communication, but also a LAN, USB, RS232C, or the like. Configure as a connected device.

The computer 21 includes an extraction unit 31 and a writing unit 32. The extraction unit 31 and the writing unit 32 are configured by a program stored in the computer 21.
The extraction unit 31 extracts a definition file corresponding to the work machine 2 from a plurality of definition files stored in the storage unit 30. Specifically, when the computer 21 is connected to the data collection device 3 by wire or wireless and the definition file is written in the definition storage unit 10 of the data collection device 3, the computer 21 first designates the work machine 2. Display the model setting screen for (input). When a model is input on the model setting screen, the extraction unit 31 extracts a definition file corresponding to the model based on the model (model name) input on the model setting screen.

  Specifically, as shown in FIG. 14, the first definition file, the second definition file, the third definition file, and the model name are associated with each other and stored in the storage unit 30. Here, for example, if “M100G” is input as the model name of the tractor on the model setting screen displayed on the computer 21, the extraction unit 31 extracts the third definition file corresponding to “M100G” from the storage unit 30. To do.

  The writing unit 32 writes the definition file extracted by the extracting unit 31 to the data collection device 3 attached to the work machine 2. For example, as described above, after the extraction unit 31 extracts the third definition file corresponding to “M100G”, the writing unit 32 transmits the extracted third definition file to the data collection device 3 connected to the computer 21. Then, the third definition file is written into the definition storage unit 10 of the data collection device 3.

  As described above, the writing system 20 according to the second embodiment is a system that writes and sets the setting conditions related to data collection to the data collection device 3 that acquires data related to the work machine output from the work machine 2. A storage unit 30 is provided for storing a plurality of definition files having different setting conditions defined for each data. In addition, the writing system 20 extracts the definition file corresponding to the work machine 3 from the plurality of definition files stored in the storage unit 30 and the definition file extracted by the extraction unit 31 to the work machine 2. And a writing unit 32 for writing to the attached data collection device 3.

Therefore, for example, when the work machine 2 is produced in a factory or the like, the data collection device 3 mounted on the work machine 2 to be produced can be adapted to the work machine 2 simply by connecting the computer 21 to the data collection device 3. The data collection conditions, that is, data storage conditions and calculation conditions can be easily written.
In particular, the extraction unit 31 extracts a definition file corresponding to the model of the work machine 2 from a plurality of definition files. Therefore, for example, manufacturers that produce work machines 2 produce a wide variety of work machines 2 such as tractors, combines, rice transplanters, etc., and each work machine 2 outputs the data output interval and data configuration (data The number of bits of the signal shown is different), but a definition file is set for each model of the work machine 2 and the definition file corresponding to the model is written in the data collection device 3 using the computer 21, so that Data can be shared.

As described above, if the work equipment 2 is equipped with the data collection device 3 having the definition file corresponding to the model of the work equipment 2, data (operation data) during operation of the work equipment 2 can be easily collected. For example, when the work machine 2 is an agricultural machine such as a tractor, a combine machine, or a rice transplanter, it is possible to collect operation data when working on the agricultural machine.
For example, when a cultivator is connected to the rear part of the tractor as a working device and the tractor is operated, operation data such as the rotational speed of the rotary, the load of the rotary, the engine speed, the vehicle speed, and the working depth is output to the in-vehicle network. . The control unit 6 can acquire operation data such as a rotary speed, a rotary load, an engine speed, a vehicle speed, and a tilling depth. Note that the rotary speed, rotary load, engine speed, vehicle speed, tilling depth, and the like are detected by an electronic device (electrical component) such as a sensor attached to the tractor or the tilling device.

  Alternatively, when the working device connected to the tractor is a fertilizer spraying device, a pesticide spraying device, or a seeding spraying device, the control unit 6 controls the vehicle speed, engine speed, spraying amount (fertilizer spraying amount, pesticide spraying amount, seeding spraying). Operational data such as volume) can be acquired. The application amount (fertilizer application amount, agricultural chemical application amount, seeding application amount) is also detected by an electronic device (electrical component) attached to the tractor, the fertilizer application device, the agricultural chemical application device, or the seed application device.

When the working device is a harvesting device, data such as vehicle speed, engine speed, and harvest amount are output to the in-vehicle network N1, and the vehicle speed, engine speed, and harvest amount can be acquired as operation data. The harvest amount is also detected by an electronic device (electrical component) attached to the tractor or harvesting device.
Now, the interval (data) that collects various operational data (rotary speed, rotary load, engine speed, vehicle speed, tilling depth, fertilizer application rate, pesticide application rate, seeding application rate, yield) as described above. There are cases where it is desired to change the storage conditions in the collection device 3 and the contents of operation data (calculation conditions in the data collection device 3). For example, there is a case where the engine speed is stored “every n receptions” but is changed to “every t time”.

Therefore, as shown in FIG. 11, the computer 21 includes a setting changing unit 33 that changes the setting conditions. The setting changing unit 33 is composed of a program stored in the computer 21.
The setting changing unit 33 changes the setting conditions corresponding to the predetermined data and stores the changed definition file in the storage unit 30. Specifically, when changing the setting conditions, the setting changing unit 33 first displays a setting screen M1 on the computer 21, as shown in FIG.

As shown in FIG. 15, the setting screen M1 includes an input unit 35a for inputting a definition file name, a display unit 35b before change for displaying setting conditions before the change for the definition file input to the input unit 35a, and a post-change And a post-change display unit 35c for displaying the setting conditions.
The pre-change display unit 35b and the post-change display unit 35c display storage conditions and calculation conditions for each data (identification information), and the post-change display unit 35c allows selection of storage conditions and calculation conditions. It has become.

  Specifically, the pre-change display unit 35b and the post-change display unit 35c display a check box (selection unit) 38 for selecting a condition (item) for each storage condition, and a condition for each calculation condition. A check box 38 for selecting (item) is displayed. When the check box 38 is checked, the storage conditions and calculation conditions corresponding to the check box 38 are selected.

The setting change unit 33 displays data (in the setting screen M1) displayed on the pre-change display unit 35b (
When the combination of the identification information) and the setting condition (storage condition or calculation condition) is different from the combination of the data (identification information) displayed on the display unit 35c after change and the setting condition (storage condition or calculation condition), It is determined that the definition file input to the input unit 35a has been changed, and a definition file having a combination of data (identification information) selected by the display unit 35c after change and setting conditions (storage conditions and calculation conditions) is stored. Store in unit 30.

  For example, as shown in FIG. 15, when the file name (NB0001) corresponding to the first definition file is input to the input unit 35a, the setting screen M1 is displayed on the display unit 35b before change and the display unit 35c after change. Displays the storage conditions and calculation conditions corresponding to the definition file. Here, in the pre-change display section 35b, the storage condition of the engine speed is displayed as “every n receptions” (the check box 38 corresponding to every n receptions is checked). ), If the check box 38 corresponding to “every t time” is checked in the post-change display unit 35c and the change button 37 displayed on the setting screen M1 is selected, the setting change unit 33 displays the engine rotation. It is recognized that the data storage condition corresponding to the number has been changed from “every n receptions” to “every t hours”. Then, the setting changing unit 33 stores the changed first definition file in the storage unit 30. At this time, the setting changing unit 33 does not overwrite the first definition file after the change without overwriting the first definition file before the change, leaving the first definition file before the change, and the first definition file after the change. Is stored in the storage unit 30. For example, the setting changing unit 33 creates a new file name by adding a number or the like indicating the version to the file name indicating the first definition file before the change, and stores the changed first definition file with the new file name. To remember. For example, as illustrated in FIG. 16A, the file name of the first definition file after the change is “NB0001-ver2”, and the first definition file after the change is stored in the storage unit 30.

  As described above, if the definition file is changed, the changed definition file, that is, the setting condition can be written corresponding to the work machine 2. For example, if “M110C” is input as a model name on the model setting screen M2 as shown in FIG. 16B, the extraction unit 31 accesses the storage unit 30 to define the first definition corresponding to “M110C”. Extract the file name of the file. Here, if there are a plurality of file names corresponding to the same model name, the extraction unit 31 sets the model names of all the first definition files, for example, “NB0001” and “NB0001-ver2”. It is displayed on the screen M2. When any one of the plurality of first definition files displayed on the model setting screen M2 is selected, the extraction unit 31 extracts the first definition file corresponding to the selected file name from the storage unit 30. To do. For example, when the first definition file with the file name “NB0001-ver2” is selected on the model setting screen M2, the extraction unit 31 extracts the first definition file with the file name “NB0001-ver2”. . Then, the writing unit 32 transmits the extracted first definition file of “NB0001-ver2” to the data collection device 3 connected to the computer 21, and stores the first definition file in the definition storage unit 10 of the data collection device 3. Write.

  As described above, the writing system 20 includes the setting change unit 33 that changes the setting condition corresponding to the predetermined data and stores the changed definition file in the storage unit 30, and the extraction unit 31 is stored in the storage unit 30. The definition file after the change corresponding to the work machine is extracted from the plurality of stored definition files, and the writing unit 32 stores the definition file after the change extracted by the extraction unit 31 in the work machine 2. Since the data is written in the data collection device 3 to be mounted, the setting conditions can be changed even after the setting conditions are once written in the data collection device 3.

In the above example, when there are a plurality of definition files corresponding to the same model, the extraction unit 31 displays a plurality of definition files on the model setting screen M2, but instead, the extraction unit 31 When there are a plurality of definition files corresponding to the same model, only the newest definition file may be extracted from the storage unit 30.
In the second embodiment described above, when there are a plurality of definition files corresponding to the same model, a plurality of definition files are displayed on the model setting screen M2, and the definition file to be written can be selected. The definition file is written, or only the newest definition file is written, but the information indicating whether or not the definition file is writable is added, and the writable definition file is written. Also good.

As shown in FIG. 11, the computer 21 includes a permission setting unit 36 that sets information as to whether or not the definition file can be written. The permission setting unit 36 includes a program stored in the computer 21.
When there are a plurality of definition files corresponding to the same model, the permission setting unit 36 displays a writing setting screen M3 for setting writing of the definition file, as shown in FIG. In the writing setting screen M3, the model name and the file name of the definition file are displayed, and a check box (selection unit) 39 for setting whether to permit writing corresponding to each file name is displayed. Yes. When the check box 39 is selected on the write setting screen M3, the definition file corresponding to the selected check box 39 can be written. In other words, the storage unit 30 stores information on permission or non-permission of writing set on the writing setting screen M3 together with the definition file.

  As described above, in the case where the file writing permission / non-permission information is associated with the definition file and stored in the storage unit 30, the extraction unit 31 first selects the plurality of definition files stored in the storage unit 30. Refer to the definition file corresponding to the work implement. Then, the extraction unit 31 extracts only the definition files that are allowed to be written from the referenced definition file. The writing unit 32 transmits the definition file that is the write permission extracted by the extraction unit 31 to the data collection device 3 attached to the work machine 2 and writes the definition file.

  As described above, by providing the permission setting unit 36, even if there are multiple definition files corresponding to the same model by repeatedly changing the definition file, the definition is made in accordance with the purpose and specifications of collecting data. By setting permission or disapproval of file writing, only the necessary definition file can be written to the data collection device 3 according to various situations.

In the above-described embodiment, the writing of the definition file to the data collection device 3 has been described. However, a program (a program for changing setting conditions) may be used instead of the definition file. That is, the program can be written in the data collection device 3 by replacing the definition file described above with the program.
That is, the writing system 20 may include a storage unit 30 that stores a plurality of programs having different setting conditions defined for each data to be collected. In addition, the writing system 20 is equipped with an extraction unit 31 that extracts a program corresponding to the work machine 3 from a plurality of programs stored in the storage unit 30, and the program extracted by the extraction unit 31 is attached to the work machine 2. A writing unit 32 for writing to the data collection device 3 may be provided. The extraction unit 31 may extract a program corresponding to the model of the work machine 2 from a plurality of programs.

  Furthermore, the writing system 20 may include a setting changing unit 33 that changes setting conditions corresponding to predetermined data and stores the changed program in the storage unit 30. The extraction unit 31 extracts a changed program corresponding to the work machine from a plurality of programs stored in the storage unit 30, and the writing unit 32 is a changed program extracted by the extraction unit 31. May be written in the data collection device 3 attached to the work machine 2. The writing system 20 may include a permission setting unit 36 that sets information about whether or not a program can be written.

The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
In the above-described embodiment, for example, items having different storage condition modes (methods) are exemplified, but even if the storage condition modes (methods) are the same, the contents indicated by the storage conditions are slightly different. It may be considered as separate storage conditions.

For example, in the storage condition, the mode (method) of the storage condition is clearly different from “every n receptions” and “at the time of change”. Different numerical values may be different storage conditions. In other words, “every 3 receptions” and “every 10 receptions” have different storage intervals, so these are different storage conditions, and storage conditions with different “n” values are prepared for each model. May be. In the storage conditions, it is desirable to change the numerical value “n” indicating the number of receptions and the numerical value “t” indicating time on the setting screen M1.

  Similarly, even if the mode (method) of the calculation conditions is the same, the contents indicated by the calculation conditions may differ as much as possible as different calculation conditions. For example, in the calculation condition, “accumulation” and “frequency” are clearly different in the mode (method) of the calculation condition, but even if “frequency”, the value of the “specified range” is different. Separate calculation conditions may be used. That is, in the engine speed, the range of “600 rpm to 800 rpm” as the first designated range is different from the range of “580 to 800 rpm” as the first designated range, and these are different calculation conditions. And calculation conditions with different numerical values in the designated range may be prepared for each model. In the calculation conditions, it is desirable to change the numerical value of the designated range indicated by “count” or “frequency” and the designated value indicated by “count” on the setting screen M1.
