Abstract

PURPOSE:To enable the use of a compressor while fully developing its performance by judging the arrival of inspection time by means of a microcomputer, and by providing a device for informing the contents of inspection and the method for treatment by means of a mark display or letter display, so that correct and regular inspection and maintenance can be carried out. CONSTITUTION:A maintenance monitor is constituted as a microcomputer device in such a way that a microcomputer 1 normally calculates and compares the time an operating signal 6 is turned ON with a real timer IC 2; the operation time is displayed on an indicator 4; the operation time, the time, setting value etc. are stored in a memory 3; and the stored data required for the control such as the integrated operation time are backed up by a battery 9 so that the stored data are not extinguished at the time of power failure or power supply OFF. And, as the indicator 4, lamps and digital indicators are generally used, and the contents of maintenance time arrival can be indicated so as to be changed by the color, number of lamps, and mark indication, however, if a liquid crystal character module or graphic module is used, usability can be improved by displaying the contents of inspection and the treatment thereof by means of letters as the substitution of an instruction manual.

It cannot be used for inspection locations where there are many variables. In addition, when calculating the inspection timing from the operating hours, when using the compressor for automatic start/stop, the operating hours of - days are extremely short and inspections will not be performed even if the inspection standards specified in the instruction manual are exceeded. ,
Problems occur due to aging. For this reason, the inspection timing varies depending on the user's usage conditions, and there is no consideration given to maintaining the maintenance standards described in the instruction manual, resulting in an uncertain inspection timing decision.

The maintenance monitor of the present invention utilizes the memory and arithmetic 2 judgment function of the microcomputer to add the maintenance time based on the operating time of - days.If the operating time is less than the set operating time, the maintenance time is added to the memory of the set operating time. If the operating time exceeds the set operating time, the actual operating time is added to the maintenance time. As a result, maintenance time that meets appropriate maintenance standards can be obtained even for compressors that automatically stop due to pressure-following operation, and the user can be notified of inspections at an early stage. Trouble caused by parts deterioration due to changes can be prevented, and there is no mismatch with maintenance standards in the instruction manual. Also, if you set a reference time, it will depend on the number of times you reach it.

The operating time is compared with the real timer IC2, and the operating time is displayed on the display 4. The microcontroller has a memory 3 that stores operating time, time, setting values, etc., and is powered by a battery 9 so that the stored data necessary for control, such as the accumulated operating time, does not disappear during a power outage or when the power is turned off. Backing up. Other functions of the maintenance monitor include a remaining time switch 8 to display the remaining time until the mincing time on the display 4, and a warning display to the display 4 and an alarm output to the relay 5 when the mincing time has arrived. A reset switch 7 is provided to reset the system when the system is in use, and constitutes a maintenance monitor as a microcomputer device.

Also, the real timer IC2 calculates whether one day has passed and sets a flag on the counter B. - When the day has passed, the memory A and the set value C are compared, and after the comparison, the memory A is cleared and the driving time for the next day is added. When the comparison result is less than the set value C, the daily basic operating time of the setting C is added, and when it is greater than the set value C, the daily operating time of the memory A is added to the memory C. is compared with the set value A, which is the standard maintenance time, and when it has reached the set value, the counter A is set to +
1 is added, the 1 display 4 indicates that it is time for maintenance, and the relay 5 is turned on. The type of maintenance period is determined based on whether the counter A is an odd number or an even number, and the contents are changed and displayed on the display 4 accordingly. Furthermore, if the maximum value of the counter B is set as the set value B, it is possible to warn that it is time for an overhaul when the set value B is reached. Also, when the operating time on -day is 0, this operation is not performed and each memory is
Assume that the sum is added. When there is a power outage or the power is turned off, the memory and counters are not cleared but stored using the battery 9, so that the data will not be deleted. The display 4 is generally a lamp or a digital display, and can display the maintenance due date in different colors, number of lamps, and symbols, but if a liquid crystal character module or graphic module is used, it can be displayed in text. It is also possible to improve usability by using the inspection contents and processing as a substitute for an instruction manual.

For this reason, the reset switch 7 is used as a base, and the remaining time switch 8 is used as a sub-switch, so that the reset is performed by operating two switches. To perform a reset operation, hold down the reset switch 7 and press the remaining time switch 8 X times 0N1 within T time.
By turning it OFF, a reset signal is taken into the microcomputer 1, and after X times, the maintenance time display on the display 4 and the output of the relay 5 are cleared. However, even if the maintenance time display is not reset, it is considered that the next maintenance control will not be activated and the maintenance time will not be delayed. In addition, a power outage or power OFF may occur while the maintenance time display is not reset.
Even if the alarm is triggered, the alarm will be stored in the battery 9 and will not disappear.
