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 management method for managing the operating status of a mobile work machine such as a construction machine operating in a certain area, and a mobile work machine for the management system. Work machine, user device, and master device.

[0002]

2. Description of the Related Art Generally, construction machines (movable work machines) such as hydraulic excavators and bulldozers are used in buildings, factories,
Since it is often used in various construction sites (work sites) such as landfills under extremely severe conditions, appropriate maintenance management is required for machine abnormalities and failures. Since specialized knowledge is required for the maintenance management, the manufacturer who provides the work machine usually performs maintenance management on behalf of the customer.

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 for repair / recovery by telephone, etc. Technicians (maintenance personnel) are dispatched to repair and restore work machines. However, at this time, if the work site is a remote place or is suddenly moving to another area due to changes in the work plan, etc., 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 Unexamined Patent Publication No. 8-14412, a management system has been proposed which solves such a problem and enables efficient maintenance management of the working machine. This system collects various data (for example, operating time, engine speed, hydraulic pump discharge pressure, etc.) related to the working state of the working machine on the working machine side, and the collected various data is attached to the working machine. From the wireless communication device (child device) to the above management unit through the communication device (parent device) connected to the work machine management unit (field office, customer office, manufacturer, etc.) via a telephone line. Then, it can be managed by the management side.

[0005]

However, in such a conventional management system, the above-mentioned various types of data transmitted from the work machine are centrally managed (stored) by the management unit side via the master unit. Therefore, the data management load on the side of the management unit may increase, delaying the determination required for maintenance management of the work machine, and delaying measures for abnormalities and failures of the work machine.

Further, in the above management system, since various data collected by the work machine are transmitted to the management unit through the master unit arranged at each work site, the configuration of the entire system is extremely large. It has become complicated and large-scale. Further, in the above management unit, for example, based on various data transmitted from the work machine, it is manually judged whether or not the work machine needs to be repaired, and if repair is required, a maintenance person is dispatched. Since the procedure for requesting a work machine is included, there is still a possibility that the measures for an abnormality or failure of the work machine may be delayed.

For example, when a failure occurs in the work machine, a certain error code is transmitted to the management section. From this error code, the cause of the failure of the work machine at that time can be known. I can not grasp the details such as the history of the operating state of the work machine until the occurrence, so
It is very difficult to quickly determine the correct action for the failure.

The present invention was devised in view of such problems, and significantly reduces the data management processing (load) in the management unit (parent device), and the failure diagnosis process of the working machine in the parent device. It is an object of the present invention to perform the maintenance automatically and quickly without any manual operation and to efficiently perform the maintenance management of the work machine.

In the following, the above-mentioned operations are performed by the construction machine 1,
2, the user station 3 and the master station 4 will be described in detail. (1) Description of Operations of Construction Machines 1 and 2 First, here, operations of the construction machines 1 and 2 will be described with reference to FIG.
2 is a flowchart (steps A1 to A11, A1)
3 to A16).

First, in the construction machines 1 and 2, the communication control unit 124 of the data collection device 12 determines whether or not a data transmission request is received from the user station 3 (or the parent station 4) (step A1) If the data transmission request has not been 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 less than a predetermined value (step). From the NO route of A1, step A2).

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 the variable N to "0", and the normal / abnormal judgment unit 1
21 is started (from NO route of step A2 to step A3). The normality / abnormality determination unit 121 determines whether or not the data regarding the operating states of the construction machines 1 and 2 detected and input by the detection unit (sensor) 11 is abnormal (steps A4 and A5).

If the input data is abnormal (step A5)
If it is determined to be YES), the normal / abnormal determination unit 121
Activates the error code generation unit 123 to generate an error code corresponding to the abnormality, sets (adds) the error code to the input data (step A6), and outputs the error 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, normal
The abnormality determination unit 121 directly inputs the input data into the storage unit 12
It is stored in a predetermined address area of No. 2 (from NO route of step A5 to step A7). Normality / abnormality determination unit 12
When the storage process of the input data in the storage unit 122 is completed as described above, the first notification 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 that time, it is determined whether or not the variable N has become equal to or _larger 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 Continue (NO route in step A9). For example, if N _MAX = 99, the above step A is performed until 100 pieces of data are stored in the storage unit 122.
The processes of 4 to A9 are 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 of step A9). Step A1
0) If the abnormal data 18 is stored (that is, if the detection result of the detection unit 11 is abnormal), the abnormal data 18 and the data 19 (see FIG. 5) stored immediately before are stored in the communication device. Through the 13, the construction machine 1 to the user station 3,
The construction machine 2 transmits to the master station 4 (YE in step A10)
From the S route, step A11).

On the other hand, if the abnormal data 18 is not stored in the storage unit 122, the first communication control unit 124A performs the processing from step A1 (NO route of step A10). By the way, when the data transmission request is received from the user station 3 (or the parent station 4) in the above step A1, the first communication control unit 124A causes the communication device 13 to operate.
A data transmission confirmation signal is transmitted to the user station 3 (or the parent station 4) through the (YES route from step A1 to step A13), and a waiting state for receiving the data transmission permission signal from the user station 3 (or the parent station 4) is received. (Step A14
NO route).

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

In step A2, if the storage capacity of the storage unit 122 is less than or equal to the predetermined value,
Similarly to the above, when the data transmission permission signal is received, all the data stored in the storage unit 122 is transmitted to the user station 3 (or the parent station 4) through the communication device 13, and then the storage content of the storage unit 122 is stored. Is cleared (NO in step A2
From the root, steps A13 to A16).

Thus, 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, so that the normality / abnormality of the construction machines 1 and 2 can be clarified. Can manage. In addition, in the present embodiment, when the data regarding the states 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 through the user station 3 and the construction machine 2 directly to the master station 4. Based on the relationship with the data obtained immediately before the abnormality data 18, the history and causes of the abnormality of the construction machines 1 and 2 can be verified very easily.
It is possible to promptly deal with the abnormality or failure of item 2.

Further, in the construction machines 1 and 2 described above, when the remaining storage capacity of the storage unit 122 becomes less than or equal to a predetermined value, all the data stored in the storage unit 122 is stored in the upper user station 3 and the master station 4. Therefore, it is possible to prevent loss of data due to loss of storage capacity of the storage unit 122. Therefore, the data obtained on the construction machines 1 and 2 side can be managed by the user station 3 and the master station 4 side without omission while the storage capacity required for the storage unit 122 is minimized. Abnormality / fault diagnosis processing and reliability of processing results will be greatly improved.

In this embodiment, after all the data stored in the storage unit 122 has been transmitted to the user station 3 and the master station 4 as described above, the stored contents of the storage unit 122 are cleared, so that the above data is stored. One storage unit 122
The data management part of the construction machines 1 and 2 can be greatly simplified. Further, when the construction machines 1 and 2 described above receive a data transmission request from the user station 3 and the parent station 4, the data stored in the storage unit 122 is transferred to the user station 3 and the parent station 4 in response to the data transmission request. Since it is transmitted to the station 4, the maintenance personnel of the construction machines 1 and 2 can arbitrarily send the data managed by the construction machines 1 and 2 on the side of the user station 3 and the master station 4 located away from the work site. It can be acquired and verified, and contributes greatly to improving the maintainability of construction machines 1 and 2.

In the above example, N = 0 to N _MAX stored in the storage unit 122 when N ≧ N _MAX.
It is determined whether or not the abnormal data 18 is stored in the data group of 1. However, this determination may be performed every time the 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 part different from that shown in FIG. 12 will be described.
If the storage capacity of 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 states of the construction machines 1 and 2 detected and input by the detection unit 11 is abnormal. (From 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 normality / abnormality determining unit 121 activates the error code generating unit 123 to generate an error code corresponding to the abnormality. 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, normal
The abnormality determination unit 121 directly inputs the input data into the storage unit 12

When the storage process to (1) is completed, the data collection device 12 determines whether or not the abnormal data 18 is stored in the storage unit 122 by the first communication control unit 124A (step A10). The 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, in the user station 3, the data management device 32 determines whether or not the parent station 4 has inquired of the repair necessity of the construction machine 1 (step C1), and if the inquiry is received,
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 YES route of step C1 to step C2). In addition, after such display of the display is finished, the reception state of the inquiry notification of the necessity of repair is reset.

On the other hand, when the inquiry about the necessity of the repair is not received (including after the above display is finished), the data management device 32 causes the communication control unit 373 to input the request for the repair from the user. Computer 4
0 (NO route from step C1 to step C3). If there is a repair request, a repair request message is transmitted to the master station 4 through the 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 (from NO route of step C4 to step C5).

If the data transmission request is received, the communication control unit 373 reads the corresponding data from the storage unit 372 according to the data transmission request, and sends the corresponding data to the master station 4 through the communication device 33. The data is transmitted (YES route from step C5 to step C12). On the other hand, if the data transmission request has not been received, it is determined whether or not the data transmission request for the construction machine 1 has been generated automatically by the data transmission request sending unit 374 or by an instruction from the user computer 40 (user) (step). From the NO route of C5, step C6).

As a result, if the data transmission request is not generated, the communication control unit 373 further determines whether or not the data output request is received from the user computer 40 (from the NO route of step C6 to step C6).
7) If it is not received, the process is terminated as it is (NO route of step C7), and if it is received, the storage unit 372.
The corresponding data is read from the output, and the data is output by the output unit 377.

On the other hand, if the data transmission request is generated in the data transmission request sending section 374 automatically or by the user's instruction, the communication control section 373 sends the request through the wireless communication device 31 to the construction machine 1 (or the parent machine). To the station 4) (from the YES route of step C6 to step C
9), a state of waiting for data input from the construction machine 1 (or the parent station 4) is entered (NO route of step C10).

In this state, the construction machine 1 (or the master station 4)
When the data 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 of the present embodiment sends the data transmission request for transmitting the data managed and stored by 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 / obtained appropriately, so that the user station 3 can also arbitrarily grasp the state of the construction machine 1. This greatly contributes to decentralization of construction machine management and improvement of maintainability of the construction machine 1.

Here, the above-mentioned 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, the user station 3 always keeps the construction machine 1 at a fixed cycle.
Alternatively, the data managed and stored in the master station 4 can be requested / obtained and the necessary data can be automatically retained, which further contributes to the improvement of the maintainability of the construction machine 1.

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

Further, the user station 3 of the present embodiment displays desired stored information stored in its own storage unit 372 on the display of the external user computer 40 through the output unit 377 or prints it out. 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 can be performed very easily.

Furthermore, when the user station 3 receives the data transmission request from the master station 4, it transmits the data stored in the user station 3 side to the master station 4 side in response to the data transmission request. , The master station 4 can obtain and detect the data regarding the states of the construction machines 1 and 2 that are managed and stored by the user station 3 at any time.
It greatly contributes to the improvement of maintainability.

(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 (steps D1 to D21, D10 'to D) shown in FIG.
13 ', D18'). First, in the master station 4, when there is any input from the input device 43 (step D1), it is determined whether or not the input is a command for executing abnormality / fault diagnosis of the construction machines 1 and 2 (step S1). D2), if it is a diagnosis command, the abnormality / fault diagnosis unit 413 of the abnormality / fault diagnosis device 42 is stored in the storage unit 412.
The data stored in 1 is sequentially verified to perform an abnormality / fault diagnosis of the construction machines 1 and 2 (step D3).

As a result, if there is any abnormality / failure in the construction machines 1 and 2, the repair parts selection deciding unit 4 of the repair parts selecting unit 414.
22 selects the component information of the component file 421 corresponding to the abnormality / fault and selects and determines the component necessary for repair (from NO route of step D4 to step D5). Then, the repair parts selection unit 414 sets the processing status to the “user station 3 (or construction machine 2) inquiry for repair necessity” state (step D6) and stores the selected parts information in the necessary storage unit 412. (Step D7).

As a result of the abnormality / fault diagnosis, if there is no abnormality / fault in the construction machines 1 and 2, a message to that effect is stored in the storage unit 412.
(Step D7: YES route 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 / fault diagnosis device 42 (CPU 45) determines whether or not the data from the user station 3 or the construction machine 2 is received. It is determined (from NO route of step D2 to step D8), if received, the received data is stored in the storage unit 412 (YES route of step D8 to step D9), and if not received, further data transmission is performed. The request sending unit 374 determines whether or not a data transmission request for the construction machine 1 is generated automatically or by an instruction from the user computer 40 (user) (from NO route of step D8 to step D10).

As a result, if the data transmission request is not generated in the data transmission request sending section 374, the error /
The failure diagnosis device 42 determines whether the communication control unit 419 receives a data transmission request from the user station 3 (from NO route of step D10 to step D1).
0 '). If the data transmission request is received from the user station 3, the communication control unit 419 sets the data stored in the storage unit 412 in accordance with the data transmission request.
Through the user station 3 (Y in step D10 ').
From the ES route, step D11 ').

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

If the data output request is not received from the input device 43, the communication control section 419 refers to the above processing status and determines whether the processing status is "repair necessity inquiry" state or not. Yes (from NO route of step D12 'to step D11). As a result, if the processing status is in the "requirement of repair necessity" state, the user of the master station 4 is notified to that effect through the input device 43, and a command input waiting state is entered.

When the user receives this notification and confirms whether or not the repair is necessary, the user inputs a predetermined command (confirmation command: including confirmation message) from the input device 43, whereby the communication control unit 419 is activated. Activates the repair necessity inquiry unit 415, and the repair necessity inquiry unit 415 transmits the content (message) of the command to the user station 3 through the communication device 41A (YES route from step D11 to step D16).

On the other hand, when the necessity of repair is not confirmed (including after the confirmation is already made), the abnormality / fault diagnosis device 42 determines whether or not there is a repair request from the user station 3 (step D11). From NO route of step D1
2) If there is a repair request, it is determined whether or not the ordering command is input from the input device 43 (step D1).
From the YES route of 2, step D13).

As a result, if the ordering command is input, in the abnormality / fault diagnosis device 42, the parts ordering unit 41
6 instructs the parts storage 5 to order and transport the necessary parts based on the parts information stored in the storage unit 412 as described above (YES route from step D13 to step D14), and to that effect (necessary). The parts order information) is stored in the necessary parts order information storage 418 (step D15). If the ordering command has not been input, the process ends (NO route of step D13).

However, when direct communication is performed between the construction machine 2 and the master station 4, it is determined whether the repair request is necessary unless the user of the construction machine 2 belongs to the company that manages the construction machine 2. You can't do that, so you can't use the above procedure.
In this case, the necessity of repair is confirmed by offline communication such as telephone, and information such as whether to repair, request for repair, information on parts, etc. is separately input from the input device 43 and stored in the storage unit 418. Will be.

In the parts storage 5, as described above, the master station 4
When an order is placed for a part from the robot, the robot automatically finds the necessary part from the parts shelves classified by part type, packs the necessary part, and then attaches a destination tag to the necessary part. By displaying the transportation destination (site address), the necessary parts are automatically transported to the site (preparation)
Carry out.

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

If the repair is not completed, the process is finished as it is (NO route of step D17). By the way, if the data transmission request is generated in the above step D10, the data transmission request is transmitted.
1A to the user station 3 (Y in step D10)
From the ES route to step D19), a state of waiting for data input from the user station 3 is entered (NO route of step D20). When data is transmitted from the user station 3 in this state, the abnormality / fault diagnosis device 42 stores the data in the storage unit 412 (step D21).

[0138] Next, focusing on the above-mentioned processing for charging the electronic banking system 8 for the repair cost, the sequence diagram (steps E1 to E13) shown in FIG. 16 for the processing of the user station 3 and the parent station 4 will be described.
