And a judgment means for reading the maintenance predicted value to be performed from the model-specific maintenance rank table 26A, reading the maintenance actual value of the machine from the machine-specific maintenance management data table 27A, and judging the magnitude of the maintenance actual value with respect to the maintenance predicted value. . The determining means has a means for calculating a payout on condition that the difference between the predicted maintenance value and the actual maintenance value is smaller than a preset value.

[Management Method] Here, the agent Dn makes a maintenance contract with the client C1 who owns the machine M1, and
FIGS. 8 and 9 show a case where the machine M1 is maintained.
This will be described with reference to FIG. At the time of the maintenance contract, when the client (agent) terminal Dn requests the server SV for the model-specific maintenance rank table 26A, the server SV sends the model-specific maintenance rank table 26A in response to the request, and the display means 12 Is displayed. Here, a maintenance contract is made while checking the model (A to Z) and the contract rank (R1 to R4) of the model-specific maintenance rank table 26A displayed on the display unit 12. At this time, in order to determine the contract rank, the use conditions and the operating environment conditions of the machine M1 are taken into consideration, the contract rank suitable for them is selected, and the contents of the maintenance contract are input from the input means 11. That is, the machine number, model, contract rank, maintenance contract start date, maintenance contract operation time, use conditions, and operation environment conditions of the machine M1 are input. Then
These data are transmitted to the server SV via the computer network 1 and stored in the unit-specific maintenance management data table 27A in the server SV.

On the server SV side, first, maintenance management item tables 23A to 23C corresponding to the model data are extracted from the standard condition DB, and then the maintenance management item tables 24A to 24 corresponding to the input operating environment conditions and usage conditions.
C, 25A to 25C are extracted from the operating environment condition DB and the use condition DB. Of these, items different from the maintenance management item tables 23A to 23C of the standard condition DB are extracted, and are extracted from the maintenance management item table 23A of the standard condition DB. ~ 23C
Replace with As a result, necessary parts and services under the input operating environment conditions and usage conditions are extracted. From these, maintenance management recommended information at each operating time (for example, recommended parts replacement information at a certain operating time, etc.) ) Is predicted and transmitted to the client terminals DT, CT1, and CT2 as maintenance management recommended information. The agency executes the maintenance service based on the information, and inputs the accompanying expenses from the input unit 11 each time. The operating time is also input periodically. Then, these data are also transmitted to the server S via the computer network 1.
V and is stored in the unit-specific maintenance management data table 27A in the server SV.

The maintenance actual value J accumulated in the maintenance actual value [J] column of the maintenance management data table 27A for each unit is the machine M
1 increases gradually as the operating time (or contract period) increases. For example, as shown in FIG.
The actual maintenance value J also increases with an increase in the operating time H of No. 1. Here, the part where the actual maintenance value J is gradually increasing indicates a case where normal maintenance and inspection work is performed, and the part where the actual maintenance value J is rapidly increasing is an overhaul (for example, an engine). The figure shows the case where expensive work such as repair of components and components is performed. FIG.
, K is a predicted maintenance value, which is an amount of cost that is predicted necessary for maintenance within the maintenance contract operating time.
Further, A and B are values set in advance on the minus side with respect to the maintenance predicted value K, and are differences from the maintenance predicted value K. However, A <B.

On the other hand, the server SV executes the processing shown in FIG. 9 for the machine whose operation time has reached the maintenance contract operation time. In ST (step) 1, the machine data whose operating time reaches the maintenance contract operating time is extracted from the maintenance management data table 27A for each machine. In ST2, the maintenance prediction value corresponding to the model of the extracted car data and the contract rank is read from the model-specific maintenance rank table 26A. In ST3, it is determined whether or not the difference between the predicted maintenance value K and the actual maintenance value J exceeds a preset value B. That is, the calculation of B <KJ is performed. As a result, B <
If KJ, go to ST4; if B <KJ, S
Proceed to T5.

In ST4, a payout is calculated. In this case, the difference between the predicted maintenance value K and the actual maintenance value J may be used as the dividend as it is, or a predetermined ratio with respect to the difference may be calculated as the dividend. After the processing, the process proceeds to ST6. In ST5, it is determined whether or not the difference between the predicted maintenance value K and the actual maintenance value J is within the range of the preset values A and B. That is, the calculation of B ≧ K−J ≧ A is performed. As a result, if B ≧ K−J ≧ A, the process proceeds to the end, and B ≧ K−J
If not ≧ A, the process proceeds to ST6. In ST6, the contract rank in the model-specific maintenance rank table 26A is reviewed. That is, when the difference between the predicted maintenance value K and the actual maintenance value J is equal to or larger than the preset value A, it is determined that the difference is not within the allowable error, and the contract rank in the model-specific maintenance rank table 26A is reviewed. Specifically, the contract rank in the model-specific maintenance rank table 26A is raised and lowered in consideration of the use conditions and operating environment conditions of the machines stored in the maintenance management data table 27A. That is, the contract rank is raised and lowered so that the predicted maintenance value K approaches the actual maintenance value J. Then, at the time of a subsequent maintenance contract, a maintenance contract is concluded at the revised contract rank. Note that the maintenance prediction value K
When the maintenance result value J exceeds the contract rank, the contract rank is reviewed, and a maintenance contract is concluded with the revised contract rank at the time of the subsequent maintenance contract.

[Effects of the Embodiment] (1) After the maintenance contract of the machine with which the maintenance contract has been completed, the predicted maintenance value corresponding to the model and contract rank of the machine is read from the model-specific maintenance rank table 26A, and the machine is checked. Maintenance result data table 27 for each unit
A is read from A, and the magnitude of the actual maintenance value J with respect to the predicted maintenance value K is determined. Therefore, if the actual maintenance value J is significantly lower than the predicted maintenance value K, the profit is returned to the maintenance recipient, and the contract rank is reviewed. If the actual maintenance value J is higher, the burden on both parties to the maintenance contract can be properly adjusted by reviewing the contract rank. In addition, since the predicted maintenance value K is compared with the actual maintenance value J based on the cost actually involved in the maintenance, the negotiation at the time of the subsequent maintenance contract can be easily performed.

(2) In particular, the present system includes client terminals DT, CT1, and CT2 and client terminals D
T, CT1, and CT2 are provided with a server SV connected via the network 1, so that the sales representative goes to the machine purchaser with only the client terminal,
Therefore, it is only necessary to input the determined maintenance contract contents and the actual maintenance value while checking the maintenance contract contents, so that the maintenance contract can be easily and simply performed. In addition, the client terminals DT, CT1, and CT2 do not need to have the model-specific maintenance rank table 26A, the unit-specific maintenance management data table 27A, the determination means, and the like.

(3) The contract rank of the model-specific maintenance rank table 26A is classified according to the use conditions and operating environment conditions of the machine. For example, whether the machine is used in a dusty area or a highland area, or Depending on whether it is operating in cold or tropical areas, contracts can be changed. Therefore, a maintenance contract can be concluded in consideration of these conditions.

(4) The actual maintenance value J with respect to the predicted maintenance value K
Is smaller, the condition that the difference between the two is greater than a preset value B, that is, when the actual maintenance cost is smaller than the maintenance predicted value by a certain amount or more, the dividend is calculated, and the dividend is calculated. Since the money is paid to the maintenance recipient, the maintenance recipient can solve the problem of overpayment. Therefore, a great advantage that dividends will be refunded can be obtained, especially for contractors who use the machine under better operating conditions and operating conditions, or contractors who handle the machine well. Can be

(5) Provided that the difference between the predicted maintenance value K and the actual maintenance value J exceeds a preset value A,
In other words, when the actual maintenance value J exceeds the allowable range for the predicted maintenance value K, the contract rank in the model-specific maintenance rank table 26A is reviewed, and the revised contract rank is input at the time of subsequent contracts. A more appropriate maintenance contract can be signed.

(6) When reviewing the contract rank in the machine-specific maintenance rank table 26A, the review is made in consideration of the use conditions and operating environment conditions of the machine, so that proper maintenance suited to the condition of each machine is performed. You can sign a contract.

(7) The server SV has the client terminal C
A maintenance management item table corresponding to the model data, operating environment conditions and use conditions of the machines M1 and M2 transmitted from T1, CT2 and DT is extracted, and the machine M1 is extracted based on the maintenance conditions defined in the maintenance management item table. , M2, the maintenance management recommended information in a certain operation time is predicted, and the predicted maintenance management recommended information is displayed on the display unit 20.
Machines M1, M without burdening users and agents
2. It is possible to easily obtain optimum maintenance management recommended information in consideration of the individual operating environment conditions and use conditions. for that reason,
Machine management work for users and distributors is also easy,
In particular, the management schedule for maintenance and overhaul can be easily set, so that the man-hour for machine management can be reduced. Moreover, the cost of the life of the machine can be predicted.

(8) Since the server SV can centrally manage the maintenance of the machines M1 and M2 owned by the clients C1 and C2, the client C1 and C2 owning the machines and the agent in charge of maintenance and the like Maintenance management can be performed without imposing a burden on stores and the like, that is, a burden associated with equipment and a burden associated with management work, so that costs for maintenance management can be reduced.

(9) Since the predicted maintenance management recommended information is distributed to the client terminals CT1, CT2, and DT, for example, it is possible to urge the user to perform necessary maintenance and management, and to the agency. Can indicate the preparation of necessary work and the supply of parts. Of course, the manufacturer can check the inventory of necessary parts, and if there is a shortage, production and procurement can be performed in advance.

[Modification] In the above embodiment, the contents of the maintenance contract (ie, the machine number, model, contract rank, maintenance contract start date, maintenance contract operating time, operation Time, use conditions, operating environment conditions, actual maintenance values, etc.), and after the maintenance contract of the machine has expired, the server SV calculates the predicted maintenance value corresponding to the model and contract rank of the machine from the model-specific maintenance rank table 26A. At the same time, the actual maintenance value of the machine is read from the maintenance management data table 27A for each machine, and the magnitude of the actual maintenance value with respect to the predicted maintenance value is determined. However, the server SV is provided with only the type-specific maintenance rank table 26A. At the client (agent) terminal DT, the model-specific maintenance rank table 26A is downloaded from the server SV. To the magnitude of the maintenance actual value with respect to maintenance predicted value may be determined.

In the above embodiment, the maintenance contract is made based on the operation time, and when the operation time reaches the maintenance contract operation time, the predicted maintenance value K and the actual maintenance value J are compared. Alternatively, a maintenance contract may be concluded on the basis of the period, and when the expiration date of the contract period is reached, the predicted maintenance value K and the actual maintenance value J may be compared. In this case, each model (A to Z) of the machine is stored in the model-specific maintenance rank table 26A.
For each of a plurality of contract ranks (R1 to R4), a maintenance predicted value relating to maintenance during the maintenance contract period is stored. In addition, the maintenance management data table 27A for each unit includes
The expiration date of the maintenance contract period (the day after the maintenance contract period has elapsed from the maintenance contract start date) is stored for each unit. Then, the control means 30 of the server SV may perform the processing shown in FIG. That is, in ST11, a designated date (arbitrary date) is input. Subsequently, in ST12, the unit data which becomes the expiration date on the input designated date is extracted from the unit-specific maintenance management data table 27A.
2 to ST6 are performed.

Further, in the above embodiment, the maintenance contract is performed in the maintenance contract operation time or the contract period, and the processing in FIGS. 9 and 10 is executed based on the contract operation time or the contract period (expiration date). However, in normal use, the contract period and the contract operation time are in a proportional relationship as shown in FIG. 11, so that if one of them is determined as a reference and the other is obtained from the relationship in FIG. The maintenance contract can be adapted to both the maintenance contract operating time and the contract period by using the type-specific maintenance rank table 26A. At this time, when the operating time is used as a reference, the latest operating time may be input. For example, the model-specific maintenance rank table 26A
For, a maintenance forecast value is set based on the contract operation time, and when the maintenance contract is made during the contract period, the contract operation time corresponding to the contract period is calculated from the relationship in FIG. The maintenance predicted value corresponding to the contract operation time may be read from the model-specific maintenance rank table 26A. Alternatively, the latest operation time may be obtained from the state measuring means 15 and the maintenance prediction value corresponding to the operation time may be read from the model-specific maintenance rank table 26A.

Further, the client terminals CT1, CT2,
As the DT, in addition to a personal computer, for example, a mobile phone or a portable information terminal (P
DA) and the like. By using such a terminal, the present system can be effectively used via a network even from a place such as a construction site where a wired communication line or a commercial power supply is not provided.

The system of the present invention is connected to the client terminals CT1, CT1 connected via the network 1.
2, it may be realized by a stand-alone computer in addition to the DT and the server SV. Even in such a case, a similar effect can be expected.

The recording medium may be, for example, a hard disk constituting storage means of a server or a client terminal, or an optical disk used for installing a program on such a hard disk. It includes any recording medium on which a computer program to be executed is stored.

In the above embodiment, the construction machine management system has been described. However, the system of the present invention is not limited to this and includes drive sources such as a mobile work machine, a stationary work machine, and a generator. It can be applied to machines in general.
