[Maintenance method] Here, the agent D
In the following, a method for maintaining the machine M1 owned by the client C will be described with reference to FIG. In the agency D or the client C, data is input from the input unit 11. For example, customer name (client C1 name), model (machine M1 model), specification, machine number, time information (month / day, time, cumulative operating time, operating time)
After inputting, for example, the operating environment conditions and the use conditions of the machine M1 are input. As the operating environment condition, for example, whether the area where the machine M1 actually works is a dust area, a highland area, or a slope site is input. As the use condition, the use condition of the machine M1, for example, the type of the used fuel, the sulfur content, the type of the lubricating oil, and the like are input. Then, the control unit transmits these pieces of information to the server SV via the computer network 1, and the measurement information measured by the state measuring unit 15 is also transmitted to the server SV via the computer network 1 at regular intervals.
V.

The server SV performs processing according to the flowchart shown in FIG. In ST1 (step 1), it is determined whether or not the customer name (client C name), model (machine M1 model), specification, machine number, time information (month, day, time, cumulative operation time, operation time) and the like are input. Check
The process proceeds to ST2 on condition that the input has been made.

In ST2, of the input data, a maintenance management item table corresponding to the model data is extracted from the standard condition DB. That is, the standard condition D shown in FIG.
From B, the maintenance management item tables 23A to 23C corresponding to the model data are extracted. As a result, necessary components and services under standard conditions are extracted from the input model data.

In ST3, it is recognized that the operating environment condition and the use condition have been input, and the process proceeds to ST4 on condition that these conditions have been input.

In ST4, the maintenance management item table 24A corresponding to the input operating environment conditions and usage conditions.
To 24C and 25A to 25C are extracted from the use condition DB and the operating environment condition DB, and items different from the maintenance management item tables 23A to 23C of the standard condition DB are extracted. That is, a maintenance management item table corresponding to the input operating environment condition and usage condition is extracted from the operating environment condition DB and usage condition DB shown in FIGS. 6 and 7, and among them, the maintenance management item table of the standard condition DB is extracted. Are extracted and replaced with the maintenance management item table of the standard condition DB. As a result, parts and services required under the input operating environment conditions and usage conditions are extracted.

In step ST5, the extracted items are
Predict maintenance management recommended information at each operation time. For example,
Based on the conditions specified for the extracted maintenance management item table and the input accumulated operating time of the machine, maintenance management recommended information such as a replacement time of each part or an overhaul time is predicted. At this time, maintenance management recommended information is predicted in consideration of measurement information from the state measurement unit 15 transmitted through the client terminal CT1.

FIG. 11 shows the prediction of the replacement time of parts.
This is performed using the data shown in (A) and (B). FIG.
In (A), the horizontal axis is the operating time, and the vertical axis is the characteristic value of each component, and the slopes of the component replacement probability straight lines a1, a2, a3, d1, and d2 are changed according to the operating environment conditions and the use conditions. It is a graph. That is, the component replacement probability straight lines a1, a2, a
The operation time until the replacement limit of the parts is reached is set shorter as the inclination of 3, d1, d2 increases. FIG. 11 (B) shows the operation time on the horizontal axis and the replacement probability on the vertical axis, and the component replacement probability straight lines a1 to a3,
The parts life distribution curves a and d corresponding to d1 and d2 are shown. In determining whether parts need to be replaced, it is determined that replacement is necessary when the operating time reaches 95% of the parts life distribution curves a and d corresponding to the input operating environment conditions and use conditions. Instructions are output. By the way, it is also possible to recommend the use of high-quality parts as maintenance management recommended information for parts whose inclination of the part replacement probability line becomes large due to the operating environment conditions and use conditions.

In ST6, the maintenance management recommended information obtained by the process in ST5 is displayed and transmitted to the client terminal CT and the agency terminal DT through the computer network 1. For example, maintenance management recommended information obtained by the process of ST5 is displayed as shown in FIG. In the display of FIG. 12, as the next recommendation content (maintenance management recommended information), the upper stage indicates that oil and oil filter replacement is required, and the operating time of the machine that is predicted to require this replacement (service meter: 9, 250),
The maintenance time (2000/3/30) is displayed,
Oil and oil filter replacement recommendations are displayed in the middle row as remarks, and the costs required to replace the oil and oil filters in the remarks column are displayed as option 1 and option 2 in the lower row.

In FIG. 12, the model, data, and operating environment conditions are displayed in the upper and lower rows on the left, the use conditions are displayed in the lower center, and jump and measurement information are displayed in the upper and lower rows on the right. Here, in the measurement information, the abnormal part of the machine estimated based on the measurement information from the state measuring means 15 and the state thereof are displayed. That is, the control unit 30 of the server SV estimates the abnormal part of the machine M1 based on the measurement information from the state measuring unit 15, determines whether or not the part needs to be replaced at this part, and displays the result on the display unit 20. There is provided a determination unit for each part to be displayed.

In FIG. 12, when the option 1 and the option 2 of the cost are clicked, detailed information on the option 1 and the option 2 is displayed as shown in FIG. In other words, the control means 30 of the server SV has a function of estimating the cost required under each condition when executing the predicted maintenance management recommended information according to some conditions, and displaying the estimated contents on the display means 20. ing. At this time, when calculating the estimated amount, the cost is estimated using the price information DB shown in FIG.

In ST7, the various data described above is stored in the machine-specific DB. The predicted maintenance management recommended information, the standard DB, the operating environment condition DB, and the use condition D
If the maintenance condition of the maintenance management item stored in B is significantly different from the maintenance condition, the control means 30
The maintenance condition stored in B is reviewed and rewritten to a value closer to the predicted value. That is, the control unit 30 stores the storage units 23 to 23 based on the predicted maintenance management recommended information and the maintenance conditions stored in the storage units 23 to 25.
A part replacement condition review means for reviewing part replacement conditions among the maintenance conditions stored in the storage device 25 is provided.

Thereafter, based on the maintenance management recommended information described above, the agent D visits the client C by a service car or the like for replacement of the oil filters 100 and 200 and the like. At this time, the agency terminal DT starts up the tour planning means so that the received plurality of clients C
From the maintenance management recommended information, the contents of the required maintenance are determined, and the visit date to each client C, the optimal visit route, the parts required for the maintenance, the time spent for the maintenance, the cost, etc. are output and displayed as a tour plan. .
Then, the staff member visits each client C according to the tour plan.

When the oil filters 100 and 200 are replaced especially on the basis of the maintenance management recommended information when the client C visits, the agent in charge of the agent D collects the used oil filters 100 and 200 and returns to the manufacturer. It is sent to the M regeneration step. When the oil filter is replaced, the barcode label of the new oil filter (see the barcode label 211 in FIG. 3) is read and stored in the repair / part use record DB as the latest replacement history. In the present embodiment, the distribution work itself involving the delivery of a new oil filter by the agent D and the collection of the used oil filter is one of the distribution means according to the present invention.

The flow after replacement of the oil filters 100 and 200 will be described below with reference to the flowchart shown in FIG. In ST1 of FIG. 14, the representative of the agent D hands over the collected oil filters 100 and 200 to the filter regeneration / production section 42 as the regeneration means of the maker M shown in FIG.

In ST2, in the filter regeneration / production section 42, the oil filters 100 and 200 are disassembled through dedicated lines (processes). This oil filter 10
During the disassembly of 0,200, the internal oil storage 150,1

Is associated with various data of the machine M1 stored in the.

In the next ST3, based on the information from the bar code label 211, the oil elements 140, 2
The number of regenerations of 40, that is, the number of cleanings, is determined. If it is determined by this regeneration that the number of cleanings of the oil elements 140 and 240 exceeds a predetermined number, or if it is determined that the components of the oil elements 140 and 240 cannot be reused by inspection, the oil is removed in step ST4. The elements 140 and 240 are discarded without being reused or removed from the line as resources for another use.

In ST5, each part of the oil filters 100 and 200 determined to be recyclable is washed, reassembled, and a new barcode label 211 is attached.

Next, as ST6, in the maker M,
The taken-out residual oil after filtration and after filtration is brought into the oil analysis section 43, and the oil analysis section 43 analyzes the residual oil and, for example, removes iron,
Analyze the contents of copper, chromium, aluminum, silicon, lead, sodium, moisture, etc., and determine whether the values are normal. Such an analysis result is transmitted to the server SV.

At ST7, upon receiving this analysis result, in the server SV, the above-described determination information generating means starts up, generates determination information from the received analysis result, and transmits this determination information to the client CT and the computer CT via the computer network 1. Output to the agency terminal DT. That is, the control means 30 of the server SV includes the oil filters 100, 2

Then, the client C and the agency D take appropriate measures based on this determination information. Also,
Regenerated oil filters 100 and 200 are manufactured by manufacturer M
Or it is stocked at agency D.

Incidentally, the maintenance management parts that need to be replaced include not only the oil filters 100 and 200 but also large and heavy client-side storage parts such as buckets and blades of construction machines. Such storage parts are replaced by the client C based on the maintenance management recommended information. In this replacement, the storage parts are replaced with parts in the stock area IA that are previously stocked, and after replacement, new storage parts are replaced. It is replenished by agency D or the like. And
Parts that are no longer needed due to this replacement are taken to the agency D side. The business itself on the agency D side, such as carrying such heavy storage parts by a trailer or the like, is also included in the distribution means according to the present invention.
