(In other words, if partial update is selected in the initial update, all devices to be managed including the devices that are to be replaced with recommended devices in the initial update can be managed equally).
- Still another device management method according to the present invention is characterized in that
- a large number of managed devices are diagnosed as normal or defective, and at least some normal New devices are deferred and the remaining normal devices are replaced with the recommended devices, and the defective devices are repaired or replaced with the recommended devices, and the initial update is performed.
- the point is to create a management database for accumulatively recording the diagnosis results of 100% diagnosis to determine whether it is normal or defective.
- analysis data indicating the failure occurrence frequency and other analysis information of each managed device include written data printed on paper or the like, or electronic data displayed on a display using a computer. Any form of data can be used as long as the contents can be displayed.
- the display format of the failure occurrence frequency in the analysis data is not limited to the numerical value display of the frequency.
- the numerical value of the number of failure occurrences on the assumption that the sampling period is the same for all the managed devices. It may be a display, etc. It is also a display form that visually shows the frequency and frequency by using graphs, tables, figures, symbols, colors, etc.
- a feature of one more preferred embodiment of the present invention is as follows:
- An analysis system that implements the device management method according to the present invention described above is also the subject of the present invention.
- One such analysis system consists of a total update that replaces all of a number of managed devices with recommended devices, and a partial update that only repairs or replaces defective devices of those managed devices with recommended devices.
- One of these is selectively performed as an initial update, and then a complete diagnosis is performed periodically to diagnose whether each device is normal or defective with respect to the total number of managed devices. If there is a failure, it will be used for maintenance or inspection work to repair or replace the defective device with a recommended device.
- Input means for inputting the diagnosis results of the exhaustive diagnosis, storage means for accumulating and storing the diagnostic results for each exhaustive diagnosis input by the input means, and the exhaustive number stored by the storage means for a plurality of times Based on the diagnosis result of the diagnosis, there is an arithmetic means for creating analysis data indicating the frequency of occurrence of defects for each managed device according to the setting program.
- the hard disk 17 of the portable personal computer 3 has trap attribute information lb for each diagnosis target trap T (in other words, a trap to be managed) lb, trap diagnosis result Ic in each diagnosis by the diagnostic device 2.
- a management database Db is stored in which trap reference information Id and the like are recorded in association with trap identification information la.
- the portable computer 3 that receives the trap diagnosis result Ic from the diagnostic device 2 operates the database update function, and the trap diagnosis result Ic and the trap reference information Id are the management database Db for the identified trap T to be diagnosed. Recorded cumulatively.
- the portable personal computer 3 uses the trap as a database creation function.
- a registration process is performed in which a management trap T (that is, an unregistered trap) corresponding to the identification information la is newly provided in the management database Db.
- the trap diagnosis result I c and the trap reference information Id transmitted from the diagnostic device 2 for the management target trap T are recorded in the management database Db.
- the ID tag 13 is attached, the trap identification information la is read, and the trap attribute information lb and the trap reference information Id are written.
- the diagnostician writes the management database Db of the portable personal computer 3 for each managed trap T, and the trap attribute information lb and trap reference information Id of each managed trap T to the memory 8 of the diagnostic device 2.
- the diagnostic device 2 diagnoses each of the traps T to be managed, and stores the diagnostic result Ic in the memory 8 of the diagnostic device 2 and writes it in the management database Db of the portable personal computer 3.
- the current status of the entire managed trap T based on the trap diagnosis result Ic for the total number of managed traps T recorded in the management database Db of the portable personal computer 3 ( For example, the defect rate, the total amount of steam leakage, and the loss due to steam leakage are reported to the management client.
- the total number of traps T to be managed for example, traps with lower vapor leakage in normal conditions, traps that are more suitable for installation, usage conditions, etc.
- the initial update is the difference between the total update to be replaced in (1) and the partial update in which only defective traps in the managed trap T are repaired or replaced with recommended traps.
- the diagnosis device 2 rediagnoses whether the replaced or repaired device is normal or defective.
- the replacement or repair of the managed trap T is completed.
- the replacement or repair of the trap T to be managed is repeated until normality is confirmed by rediagnosis.
