Abstract

PURPOSE:To decide the optimum time for replacement of a fan due to the end of its lifetime and to reduce the maintenance manhour for maintenance of the fan. CONSTITUTION:The time of replacement of a fan 1, i.e., the operating time when the replacement of the fan 1 is needed is inputted by a timer setting part 4 before the working of the fan 1 is started. Then the time of replacement is stored in a 2nd memory part 5. When the fan 1 starts its working, a counter part 2 starts to count the working time of the fan 1 and stores the counted time in a 1st memory part 3. A comparison/judgement part 6 compares the time value of the part 5 with that of the part 5 and decides the time of replacement of the fan 1 when the coincidence is obtained between both time values. Thus a fen replacement instruction signal is transmitted from a replacement instruction signal transmitting part 7.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for instructing fan replacement, and more particularly to a method for instructing when to replace a fan or fan unit used in electronic equipment.

0002

[Background Art] Conventionally, in order to avoid adverse effects on electronic equipment etc. due to fan failure, the time when the fan started operating is recorded, and maintenance personnel check the operating years of the fan or fan unit before the fan reaches the end of its service life. was being exchanged.

0003

[Problem to be Solved by the Invention] In the conventional method of instructing replacement of a fan or fan unit, maintenance personnel must record the time when the fan started operating, check the number of years that have passed, and then instruct the replacement time. However, there are problems in that there is a risk that the time for replacing the fan will be missed and a fan failure will occur, and that maintenance personnel will be burdened with the man-hours required to manage the fan or fan unit.

0004

[Means for Solving the Problems] The fan replacement instruction method of the present invention includes a replacement time setting means for setting in advance the operating time during which the fan needs to be replaced, and an operation timing means for timing the actual operating time of the fan. , Compare the operating time that requires replacement set in the replacement time setting means with the actual operating time measured by the operation timer, and the actual operating time reaches the operating time that requires replacement. Then, the fan replacement time determining means outputs a fan replacement instruction signal.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention. Before the fan 1 starts operating, the timer setting unit 4 determines when to replace the fan 1 (operation time during which conversion is required).
is input and stored in the second memory section 5. Next, when the fan is operated, the counter section 2 starts counting the operating time and stores the clock data in the first memory section 3. The timing data stored in the first memory section 3 and the replacement timing data set in advance in the second memory section 5 are inputted to the comparison/judgment section 6 and compared, and as a result, when the replacement time has come, (if they match), the replacement instruction signal sending unit 7 sends out a fan replacement instruction signal.

[0007]

[Effects of the Invention] As explained above, the present invention has the effect of reducing management man-hours for fan replacement and optimizing fan replacement timing by setting the fan or fan unit replacement timing in advance. have

Claims (1)

[Claims] 1. Replacement time setting means for presetting the operating time during which the fan needs to be replaced; operation timer means for timing the actual operating time of the fan; and a fan that requires replacement set in the replacement time setting means. Replacement time determining means compares the actual operating time measured by the operation timing means and outputs a fan replacement instruction signal when the actual operating time reaches the operating time requiring replacement. A fan replacement instruction method characterized by comprising:
