Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile work machine management system and method for managing the operation state of a mobile work machine such as a construction machine operating in a certain area, and a mobile work machine for the management system. The present invention relates to a work machine, a user device, and a parent device.

[0002]

2. Description of the Related Art In general, construction machines (mobile work machines) such as hydraulic excavators and bulldozers are, for example, buildings and factories,
It is often used under extremely severe conditions at various construction sites (work sites) such as landfills, so appropriate maintenance and management is required for machine abnormalities and failures. Since specialized knowledge is required for the maintenance management of a work machine, usually, a maker providing a work machine often performs maintenance management on behalf of a customer.

[0003] For example, when a failure occurs in a work machine at a certain work site, a customer who manages the work machine usually requests the maker to repair and restore it by telephone or the like. A technician (maintenance person) is dispatched to repair and restore the work machine. However, at this time, if the work site is remote or suddenly moved to another area due to a change in work plan, until the maintenance person actually arrives at the work site and starts repairing the work machine Can be very time consuming.

Therefore, as disclosed in Japanese Patent Application Laid-Open No. 8-144412, a management system has been proposed which solves such a problem and enables efficient maintenance management of a work machine. This system collects various data (for example, operation time, engine speed, discharge pressure of a hydraulic pump, etc.) relating to the operation state of the work machine on the work machine side, and attaches the collected various data to the work machine. From the wireless communication device (slave unit) to the management unit (work unit, customer office, manufacturer, etc.) of the work machine through a communication device (master unit) connected via a telephone line. Thus, the management unit can manage the information.

[0005]

However, in such a conventional management system, the above-mentioned various data transmitted from the work machine is centrally managed (stored) on the management unit side via the parent machine. As a result, the data management load on the management unit increases, delaying the judgment required for the maintenance and management of the work machine, and delaying measures for abnormality or failure of the work machine.

Further, in the above management system, since various data collected by the work machine is transmitted to the management unit through the master machine arranged at each work site, the configuration of the entire system is very large. It is complicated and large-scale. In the management unit, for example, based on various data transmitted from the work machine, it is manually determined whether or not the work machine needs to be repaired. In this case, there is a possibility that the processing for the abnormality or the failure of the work machine may be delayed.

For example, when any failure occurs in the work machine, a specific error code is transmitted to the management unit. From this error code, the cause of the failure of the work machine at that time can be grasped. Since details such as the working state of the working machine until the occurrence can not be grasped,
It is very difficult to quickly determine the exact action for the failure.

SUMMARY OF THE INVENTION The present invention has been made in view of such a problem, and greatly reduces data management processing (load) in a management unit (parent device), and also performs failure diagnosis processing of a work machine in the parent device. Is performed automatically and promptly without manual operation, so that maintenance and management of the work machine can be efficiently performed.

Hereinafter, the above-described operations are performed by the construction machines 1 and 2, respectively.
2, the user station 3 and the master station 4 will be described in detail. (1) Description of Operation of Construction Machines 1 and 2 First, here, the operation of the construction machines 1 and 2 will be described with reference to FIG.
2 (steps A1 to A11, A1
3 to A16).

First, in the construction machines 1 and 2, the communication control section 124 of the data collection device 12 determines whether or not a data transmission request has been received from the user station 3 (or the master station 4) (step S1). A1) If the data transmission request is not received, the second communication control unit 124B further determines whether or not the storage capacity of the storage unit 122 (data memory 16) is equal to or smaller than a predetermined value (step S1). Step A2) from the A1 NO route.

As a result, if the remaining storage capacity of the storage unit 122 is not less than the predetermined value, the second communication control unit 124
B sets “0” to a variable N, and sets the normal / abnormal judgment unit 1
21 is started (step A3 from the NO route of step A2). The normal / abnormal judging unit 121 judges whether the data on the operating state of the construction machines 1 and 2 detected and input by the detecting unit (sensor) 11 is abnormal (Steps A4 and A5).

If the input data is abnormal (step A5)
If it is determined as YES), the normal / abnormal judgment unit 121
Starts the error code generation unit 123, generates an error code corresponding to the abnormality, sets (gives) the error code to the input data (step A6), and sets it as the abnormality data 18 (see FIG. 5). It is stored in a predetermined address area of the storage unit 122 (Step A7).

If the input data is normal,
The abnormality determination unit 121 stores the input data in the storage unit 12 as it is.
2 is stored in the predetermined address area (NO route from step A5 to step A7). Normal / abnormal judgment unit 12
When the process of storing the input data in the storage unit 122 is completed as described above, the first communication control unit 124B notifies the second communication control unit 124B of this fact, and the second communication control unit 124B increases the variable N by “1”. (N = N + 1) (Step A
8), at which point, the variable N is judged whether it is greater than the maximum value N _MAX (step A9).

[0103] Consequently, if the variable N is if below yet the maximum value N _MAX, until the variable N becomes the maximum value N _{MA X,} repeating the process from step A4, to store the input data in the storage unit 122 (NO route of step A9). For example, if N _MAX = 99, the above-described step A is performed until 100 pieces of data are stored in the storage unit 122.
The processing of 4-A9 will be repeated.

When N ≧ N _MAX , the data collection device 12 determines whether the abnormal data 18 is stored in the storage unit 122 by the first communication control unit 124A (from the YES route in step A9). Step A1
0), if the abnormal data 18 is stored (that is, if the detection result by the detecting unit 11 is abnormal), the abnormal data 18 and the immediately stored data 19 (see FIG. 5) are transmitted to the communication device. Through 13, the construction machine 1 goes to the user station 3,
The construction machine 2 transmits the signal to the master station 4 (YE in step A10).
Step S11 from the S route).

On the other hand, if abnormality data 18 is not stored in storage unit 122, first communication control unit 124A performs the processing from step A1 described above (NO route in step A10). By the way, in step A1, when a data transmission request is received from the user station 3 (or the master station 4), the first communication control unit 124A
A data transmission confirmation signal is transmitted to the user station 3 (or the master station 4) through the process (from the YES route of step A1 to step A13), and a data transmission permission signal from the user station 3 (or the master station 4) is waited for. (Step A14)
NO route).

In this state, the user station 3 (or the master station 4)
When the first communication control unit 124A receives the data transmission permission signal from the communication unit 13, the first communication control unit 124A transmits all the data stored in the storage unit 122 to the user station 3 (or the master station 4) through the communication device 13 (step A14). From the YES route, step A15), the contents stored in the storage unit 122 are cleared (step A16).

If the storage capacity of the storage unit 122 is equal to or smaller than the predetermined value in step A2,
As described above, when the data transmission permission signal is received, all data stored in the storage unit 122 is transmitted to the user station 3 (or the master station 4) through the communication device 13, and then the storage contents of the storage unit 122 are stored. (NO in step A2)
Steps A13 to A16 from the route).

As described above, in the construction machines 1 and 2 described above,
When it is determined that the data relating to the state of the construction machines 1 and 2 is abnormal, an error code is generated by the error code generation unit 123. Can manage. Further, in the present embodiment, when the data on the state of the construction machines 1 and 2 is abnormal, the abnormal data 18
And at least the data obtained immediately before the abnormal data 18 are transmitted from the construction machine 1 to the master station 4 via the user station 3 and the construction machine 2 is transmitted directly to the master station 4. Based on the relationship with the data obtained immediately before the abnormal data 18, it is possible to extremely easily verify the details and causes of the abnormalities of the construction machines 1 and 2,
2 can be quickly dealt with.

Further, in the construction machines 1 and 2 described above, when the remaining storage capacity of the storage unit 122 becomes equal to or smaller than a predetermined value, all the data stored in the storage unit 122 is transferred to the upper user station 3 and the parent station 4. Thus, it is possible to prevent the storage capacity of the storage unit 122 from being lost and data from being lost. Therefore, the data obtained on the construction machines 1 and 2 can be managed without omission by the user station 3 and the master station 4 while minimizing the storage capacity required for the storage unit 122. The reliability of abnormality / failure diagnosis processing and processing results will be greatly improved.

In this embodiment, after all the data stored in the storage unit 122 is transmitted to the user station 3 and the master station 4 as described above, the storage contents of the storage unit 122 are cleared. Is stored in one storage unit 122
The data management part in the construction machines 1 and 2 can be greatly simplified. Further, upon receiving a data transmission request from the user station 3 and the parent station 4, the construction machines 1 and 2 transmit the data stored in the storage unit 122 to the user station 3 and the parent station 4 in response to the data transmission request. Since the data is transmitted to the station 4, the maintenance person of the construction machines 1 and 2 can arbitrarily manage the data managed by the construction machines 1 and 2 at the user station 3 or the master station 4 located at a place remote from the work site. Acquisition and verification are possible, which greatly contributes to improvement of maintainability of the construction machines 1 and 2.

[0111] In the above example, N ≧ N at the time when a _MAX, the storage unit 122 are stored N = 0 to N _MAX
It is determined whether or not the abnormal data 18 is stored for the data group of., But this determination may be made every time data is stored in the storage unit 122. That is, the operation (flow chart) in this case is as shown in FIG.

Here, only the parts different from those shown in FIG. 12 will be described.
If the storage capacity of the construction machines 1 and 2 is not less than or equal to the predetermined value, the normality / abnormality determination unit 121 determines whether or not the data regarding the operating state of the construction machines 1 and 2 detected and input by the detection unit 11 is abnormal. (From the NO route of step A2 to step B1).

As a result, if the input data is abnormal (if YES is determined in step B1), the normal / abnormal judging section 121 activates the error code generating section 123 and outputs an error code corresponding to the abnormal. Is generated, the error code is set in the input data (step B3), and the error data 18 is stored in a predetermined address area of the storage unit 122 (step B4).

If the input data is normal,
The abnormality determination unit 121 stores the input data in the storage unit 12 as it is.
2 is stored in the predetermined address area (NO route from step B2 to step B4). Then, the normal / abnormal judgment unit 121 stores the input data in the storage unit 122 as described above.
When the storage process to the storage device is completed, the data collection device 12 determines whether the abnormal data 18 is stored in the storage unit 122 by the first communication control unit 124A (Step A10). Subsequent processing is the same as above.

(2) Description of Operation of User Station 3 Next, the operation of the user station 3 will be described with reference to the flowchart (steps C1 to C12) shown in FIG. First, the user station 3 determines in the data management device 32 whether an inquiry about the necessity of repair for the construction machine 1 has been sent from the master station 4 (step C1).
The communication control unit 373 causes the corresponding data stored in the storage unit 372 to be displayed on the display of the user computer 40 through the output unit 377 (from the YES route of step C1 to step C2). After the completion of the display, the reception state of the notification of the necessity of repair is reset.

On the other hand, when the inquiry about the necessity of repair is not received (including after the above-mentioned display is completed), the data management device 32 uses the communication control unit 373 to input a request for repair from the user by the user. Computer 4
Then, it is determined whether or not the repair has been made (NO route from step C1 to step C3). If there is a repair request, a repair request message is transmitted to master station 4 through communication device 33 (NO route from step C3 to step C4), If there is no repair request, it is further determined whether a data transmission request has been received from the master station 4 (step C5 from the NO route of step C4).

If a data transmission request has been received, the communication control unit 373 reads the relevant data from the storage unit 372 in response to the data transmission request, and sends the relevant data to the master station 4 through the communication device 33. The transmission is performed (from the YES route of step C5 to step C12). On the other hand, if the data transmission request has not been received, the data transmission request sending unit 374 determines whether a data transmission request for the construction machine 1 has been generated automatically or in accordance with an instruction from the user computer 40 (user) (step). Step C6 from the NO route of C5).

As a result, if a data transmission request has not been generated, communication control section 373 further determines whether or not a data output request has been received from user computer 40 (from NO route in step C6 to step C6).
7) If not received, the process is terminated as it is (NO route of step C7), and if received, the storage unit 372
And reads the corresponding data from the output unit 377.
Is output to the user computer 40 through (YES route from step C7 to step C8).

On the other hand, if the data transmission request is automatically generated by the data transmission request sending section 374 or in accordance with a user's instruction, the communication control section 373 transmits the request through the radio communication device 31 to the construction machine 1 (or the parent machine). Station 4) (step C6: YES route to step C6).
9), and enters a state of waiting for data input from the construction machine 1 (or the master station 4) (NO route of step C10).

In such a state, the construction machine 1 (or the master station 4)
Is transmitted from the communication control unit 373, the communication control unit 373 stores the data in the storage unit 372 (step C1).
1). As described above, the user station 3 according to the present embodiment transmits data transmission requests for data managed and stored in the construction machine 1 or the master station 4 to at least one of the construction machine 1 and the master station 4. By providing the request sending unit 374, the data managed and stored in the construction machine 1 or the master station 4 can be requested and acquired as appropriate, so that the user station 3 can arbitrarily grasp the state of the construction machine 1 as well. This greatly contributes to decentralization of construction machine management and improvement of maintainability of the construction machine 1.

Here, the data transmission request sending unit 37
4 can automatically send a data transmission request to the construction machine 1 or the master station 4 at a predetermined time interval.
Alternatively, the data managed and stored in the master station 4 can be requested / acquired, and the necessary data can be automatically held, thereby contributing to further improvement in the maintainability of the construction machine 1.

The data transmission request sending section 374
Can output a data transmission request to the construction machine 1 or the master station 4 by performing an operation for a data transmission request by the user through the user computer 40. At any time, the above data can be obtained from the construction machine 1 or the master station 4, which greatly contributes to decentralized construction machine maintenance and improved flexibility.

The user station 3 of the present embodiment displays desired print information stored in its own storage unit 372 on the display of the external user computer 40 via the output unit 377 or prints out the desired storage information. Therefore, the user can take out and check the information managed by the user station 3 at any time, whereby the state verification of the construction machine 1 and the like can be performed very easily.

Further, when the user station 3 receives a data transmission request from the master station 4, the user station 3 transmits data stored in the user station 3 to the master station 4 in response to the data transmission request. The master station 4 can always acquire and detect data on the state of the construction machines 1 and 2 managed and stored in the user station 3.
It greatly contributes to improving the maintainability of the system.

(3) Description of Operation of Master Station 4 Next, here, the operation of the master station 4 will be described with reference to the flowchart shown in FIG. 15 (steps D1 to D21, D10 'to D10).
13 ', D18'). First, when there is any input from the input device 43 (step D1), the master station 4 determines whether or not the input is a command for performing abnormality / failure diagnosis of the construction machines 1 and 2 (step D1). D2) If the command is a diagnostic command, the abnormality / failure diagnosis unit 413 of the abnormality / failure diagnosis device 42
Are sequentially verified to perform abnormality / failure diagnosis of the construction machines 1 and 2 (step D3).

As a result, if there is an abnormality / failure in the construction machines 1 and 2, the repair part selection determining unit 4 of the repair part selecting unit 414
22 selects the component information of the component file 421 corresponding to the abnormality / failure, and selects and determines a component necessary for repair (NO route from step D4 to step D5). Then, the repair part selection unit 414 sets the processing status to the “inquire of the user station 3 (or the construction machine 2) whether or not to repair” state (step D6), and stores the selected part information in the necessary storage unit 412. (Step D7).

If no abnormality / failure is found in the construction machines 1 and 2 as a result of the abnormality / failure diagnosis, the fact is stored in the storage unit 412.
(From the YES route of step D4 to step D7). On the other hand, in step D2, if the input from the input device 43 is not a diagnostic command, the abnormality / failure diagnostic device 42 (CPU 45) determines whether data from the user station 3 or the construction machine 2 has been received. The determination is made (NO route from step D2 to step D8). If received, the received data is stored in storage unit 412 (YES route from step D8 to step D9). The request sending unit 374 determines whether a data transmission request for the construction machine 1 has been generated automatically or according to an instruction from the user computer 40 (user) (step D10 from the NO route of step D8).

As a result, if a data transmission request is not generated in data transmission request sending section 374,
The failure diagnosis device 42 determines whether the communication control unit 419 has received a data transmission request from the user station 3 (from the NO route of step D10 to step D1).
0 '). If a data transmission request has been received from the user station 3, the communication control unit 419 transmits the data stored in the storage unit 412 to the communication unit 41 in response to the data transmission request.
To the user station 3 (Y in step D10 ')
Step D11 'from the ES route).

On the other hand, if a data transmission request has not been received from user station 3, communication control section 419 further determines whether or not a data output request has been received from input device 43 (NO in step D10 '). Step D1 from the route
2 '), if the data output request is received, the output unit 41
9 ', the desired data stored in the storage section 412 is output to the input device 43 (Y in step D12').
Step D13 'from the ES route).

If a data output request has not been received from the input device 43, the communication control unit 419 refers to the processing status and determines whether or not the processing status is in the “repair necessity inquiry” state. (Step D11 from the NO route of Step D12 '). As a result, if the processing status is in the “repair necessity inquiry” state, the user of the master station 4 is notified via the input device 43 to that effect, and the apparatus enters a command input waiting state.

If the user receives this notification and confirms the necessity of repair, the user inputs a predetermined command (confirmation command: including a confirmation message) from the input device 43, and thereby, the communication control unit 419. Activates the repair necessity inquiry section 415, and transmits the contents (message) of the command to the user station 3 through the communication device 41A by the repair necessity inquiry section 415 (step D16 from the YES route of step D11).

On the other hand, when the repair necessity is not confirmed (including after the confirmation is already performed), the abnormality / failure diagnosis device 42 determines whether or not the user station 3 requests a repair (step D11). Step D1 from NO route
2) If there is a repair request, it is determined whether an order instruction command has been input from the input device 43 (step D1).
Step D13 from the YES route of Step 2).

As a result, if the order instruction command has been input, the abnormality ordering section 41
6 instructs the parts warehouse 5 to order and transport the necessary parts based on the parts information stored in the storage unit 412 as described above (from the YES route of step D13 to step D14). (Parts order information) is stored in the necessary parts order information storage 418 (step D15). If the order instruction command has not been input, the process ends (NO route in step D13).

However, when direct communication is performed between the construction machine 2 and the master station 4, it is determined whether a repair request is necessary unless the user of the construction machine 2 belongs to a company that manages the construction machine 2. No, the above procedure cannot be used.
In this case, the necessity of the repair is confirmed by an off-line communication such as a telephone, and information such as a message as to whether or not to repair, a repair request, and parts information are separately input from the input device 43 and stored in the storage unit 418. Will be.

In the parts warehouse 5, as described above, the master station 4
When a robot receives an order for parts, the robot automatically searches for the required parts from the parts shelf classified by component type, packs the required parts, and then attaches a destination tag to the required parts, for example. By displaying the transport destination (site address), the necessary parts are automatically transported to the site (preparation).
Is carried out.

On the other hand, if there is no request for repair from the user station 3, it is determined whether or not the repair of the construction machines 1 and 2 has been completed (from the NO route of step D12 to step D1).
7) If completed, the effect (repair completion data) is stored in the storage unit 412 (YE in step D17).
From the S route, step D18), the electronic banking system 8 is charged to charge the user of the repaired construction machines 1 and 2 a repair cost (repair fee + parts fee) (step D18 ').

If the repair has not been completed, the process is terminated as it is (NO route in step D17). If a data transmission request has been generated in step D10, the data transmission request is transmitted to the communication device 4.
1A to the user station 3 (Y in step D10).
From the ES route, step D19), the system enters a state of waiting for data input from the user station 3 (NO route of step D20). When data is transmitted from the user station 3 in such a state, the abnormality / failure diagnosis device 42 stores the data in the storage unit 412 (step D21).

Next, in the following, focusing on the repair billing process for the electronic banking system 8, the sequence diagram (steps E1 to E13) shown in FIG. This will be described in detail with reference to FIG. Here, a case where the core facility of the electronic banking system 8 is a bank is taken as an example.

First, as shown in FIG. 16, when it is diagnosed in the master station 4 that an abnormality / failure has occurred in the construction machines 1 and 2 (step E1), the master station 4 informs the user station 3 about the abnormality / failure. An inquiry is made as to whether or not the repair of the construction machines 1 and 2 is necessary (step E2). At this time, the master station 4 notifies the user station 3 of the estimated cost for the repair together with the inquiry.

Then, the user station 3 judges whether or not to request the repair based on the notified estimate (step E3), and if so, sends the repair request to the master station 4 together with the date and time of the repair. Notify (step E4). The parent station 4
Upon receiving this notice, the construction machines 1, 2
And the maintenance staff of the construction machines 1 and 2 so that the parts required for repair and the parts required for the repair arrive at the site (step E).
5), parts necessary for repair are arranged in the parts store 5 (step E6).

When the repair is completed by the maintenance staff (step E7), the user station 3 checks whether there is any problem in the repair (step E8).
This is notified to the master station 4 (step E9). Parent station 4
Upon receipt of this notification, the repair cost is calculated (settled) (step E10), and the cost is charged to the bank (step E11). At this time, the master station 4
At least the billing amount, the account number of the master station 4 and the account number of the user station 3 are notified to the bank.

Then, the bank performs an authentication process or the like based on the account number of the master station 4 and the account number of the user station 3, and then transfers the above-mentioned billing amount from the account of the user station 3 to the account of the master station 4. (Step E12), a payment statement is sent to the master station 4,
The payment statement is transmitted to the user station 3 by online processing (step E13). As a result, the repair cost of the construction machines 1 and 2 can be automatically reduced without the staff of the user station 3 directly going to the bank and requesting the transfer of the repair cost to the account of the master station 4. 4 will be transferred to the account.

As described in detail above, according to the present invention,
Data on the state (normal / abnormal) of the work machine is managed on the work machine side, and the data is also managed (stored) on the user device side by communication, and based on the data managed on the user device side. Since the parent device performs abnormality / failure diagnosis of the work machine, the following advantages are obtained (claims 1, 42 to 44, 50, and 55).

The state of the work machine is centrally managed while greatly reducing the data management processing (load) on the parent device and greatly improving the processing speed and processing capability of the abnormality / failure diagnosis processing by the parent device. This makes it possible to deal with abnormalities and failures of the working machine very quickly. Since it is not necessary to provide a user device with an abnormal / failure diagnosis device which is usually very expensive, the cost on the user side can be greatly reduced.

Since the processing for the abnormality / failure of the work machine is performed online (communication), it is not necessary for the maintenance person of the work machine to go to the site directly, and the labor and load of the maintenance person can be greatly reduced. . In the present invention,
As described above, since the data on the state of the work machine can be sent directly from the work machine to the parent device without the intervention of the user device, in this case, the state of the work machine Can be centrally managed in the parent device (claims 24, 66, 72).

When the work machine determines that the data relating to the state of the work machine is abnormal, an error code can be generated. Data management can be performed (claims 2, 25, 45, 67). Further, when the data relating to the state of the work machine is abnormal, the work machine described above transmits the abnormal data and at least data obtained immediately before the abnormal data to a higher-level device (user device or parent device). Therefore, the host device can very easily verify the history and cause of the abnormality of the work machine based on the relationship between the abnormal data and the data obtained immediately before the abnormal data. Thus, it is possible to quickly deal with abnormalities or failures of the working machine (claims 3, 26, 44, 66).

At this time, if the abnormal data and all the data obtained before the abnormal data are transmitted to the upper-level device side, the details of the abnormality of the work machine and the details of the abnormalities of the work machine can be obtained. The cause can be verified (claims 4, 27, 46, 68). Further, when the storage state of the work machine-side storage unit that stores data relating to the state of the work machine exceeds a predetermined capacity, all of the data stored in the storage unit is transmitted to the host device. Therefore, it is possible to prevent the storage capacity of the storage unit from being lost and data from being lost. Therefore, data obtained on the work machine side can be managed on the upper device side without omission while minimizing the storage capacity required for the storage unit, and the abnormal /
The reliability of the failure diagnosis processing and the processing result can be greatly improved (claims 5, 28, 47, 69).

After all the data stored in the work machine-side storage unit is transmitted to the higher-level device as described above, if the storage contents of the work machine-side storage unit are cleared, the data of the above-described data can be stored. Since only one storage unit is required for storage, the data management part of the work machine can be greatly simplified (claims 6, 29, 48, 70). Further, when the work machine receives a data transmission request from the higher-level device, the work machine can transmit data stored in the work-machine-side storage unit to the higher-level device in response to the data transmission request. The work machine maintainer can arbitrarily acquire and verify the data on the state of the work machine managed by the work machine at the host device located away from the work site, and maintain the work machine. (Claims 7, 30, 49, 71).

It greatly contributes to improving the maintainability of the work machine.

Here, the user device-side data transmission request transmitting section can automatically transmit a data transmission request to the work machine or the parent device at a predetermined time interval. It is possible to request / acquire the data managed and stored in the work machine or the parent device at a constant cycle, and to automatically retain necessary data, thereby further improving the maintainability of the work machine. Contributes (claims 9 and 51).

The user device-side data transmission request sending unit can output a data transmission request to the work machine or the parent device when the user performs an operation for requesting data transmission. On the device side, the above data can be obtained from the work machine or the parent device at any time as desired by the user, which greatly contributes to decentralization of work machine maintenance and improvement of flexibility.

Further, the above-mentioned host device can output desired storage information stored in the above-mentioned storage unit to the outside, so that the user can manage the information (work machine State, etc.) can be taken out and checked at any time, whereby the state verification of the working machine and the like can be carried out very easily.
4, 53, 76).

When the user device receives a data transmission request from the parent device, the user device can transmit the data stored in the user device to the parent device in response to the data transmission request. The parent device can always acquire and detect the data on the state of the work machine managed and stored in the user device. In this case as well, it greatly contributes to improving the maintainability of the work machine (claims 12 and 5).
4).

Further, the above-mentioned parent device may be provided with a parent device-side data transmission request transmitting section for transmitting a transmission request of data stored in the lower device to the lower device (user device or work machine). Since the parent device can appropriately request and acquire data managed and stored in the lower device, the state of the work machine can be intensively grasped, and the efficiency of maintenance work on the work machine can be improved. (Claims 13, 31, 56, 73).

Here, the parent device-side data transmission request transmitting section can automatically transmit a data transmission request to a lower-level device at a predetermined time interval. In the cycle, the data managed and stored in the lower-level device can be requested / acquired and the necessary data can be automatically held, so that the efficiency of the maintenance work can be further improved (claim 14). , 32,57,7
4).

Further, the above-mentioned parent device-side data transmission request sending section can also output a data transmission request to a lower device when a user performs an operation for a data transmission request. The above data can be obtained from the lower device at any time according to the user's request, which greatly contributes to the improvement of flexibility in maintenance of the work machine (claims 15, 33, 58, 75).

Further, when the master device receives a data transmission request from the user device, the master device can transmit the data managed and stored in the master device to the user device in response to the data transmission request. The user device can always acquire and verify data on the state of the work machine that is collectively managed on the parent device side, and can further improve the maintainability of the work machine (claim 1).
6, 59).

Further, in the above-mentioned parent device, it is possible to determine whether or not the work machine needs to be repaired or abnormal based on the result of the abnormality / failure diagnosis. Can be implemented,
Downtime due to abnormality or failure of the work machine can be minimized (claims 17, 35, 55, 72). At this time, the above-mentioned parent device can also determine the parts necessary for the abnormality / failure repair based on the result of the abnormality / failure repair determination, so that the parts required for the abnormality / failure repair can be accurately and quickly specified. And the recovery work for the abnormality or failure of the work machine can be performed more quickly (claims 18, 36, 60, 77). In addition, if the determination of the repair part is performed by selecting the part information of the part file based on the result of the abnormality / failure repair determination,
It is easily realized with a simple configuration.
1, 78).

Further, the above-mentioned parent device can also inquire of the user device whether or not repair is necessary based on the above-mentioned abnormality / failure repair determination result, so that the work machine always takes into account the user's intention on the user device side. Abnormality / failure repair can be carried out, and a situation in which the repair target construction machine cannot be actually repaired during operation or the like is prevented, which greatly contributes to an improvement in the operating efficiency of the working machine. , 38,6
2, 79).

As a result of the inquiry about the necessity of repair as described above, this parent device can also issue an order for necessary parts when it receives a response to the effect of repair from the user device. It is possible to minimize the time from the completion of the work to the repair of the work machine by procuring parts necessary for the repair, and to more quickly carry out the work machine abnormality or failure recovery work (claim Terms 21, 39, 63,
80).

Furthermore, in this parent device, the order information of the necessary parts can be stored in the necessary parts order information storage unit, so that it is very easy to count and order the parts order status.
