Description

DETAILED DESCRIPTION OF THE INVENTION [Outline] The present invention has a cycle for carrying out the maintenance contents for each periodic maintenance inspection item of each input / output device (I / O) under the control of an information processing device (CPU). It is recorded in a register that counts in units suitable for, the value accumulated during regular maintenance and inspection of this count value is compared with a preset reference value, and the result is displayed to perform necessary maintenance for each regular maintenance and inspection item. The contents are automatically extracted.

[Industrial application field]

The present invention relates to a regular maintenance / inspection item display device for automatically extracting necessary maintenance contents for each regular maintenance / inspection item of a plurality of input / output devices (I / O) under the control of an information processing device (CPU). is there.

[Conventional technology]

Conventionally, a single device such as a copying machine, or a plurality of input / output devices (I / O) under the control of an information processing device (CPU) such as a transaction system, such as a Japanese line printer (NLP), a card In a system that includes a reader, magnetic tape unit (MT), etc.
A mechanical counter 1 as shown in FIG. 4 is provided in each device, and a drive pulse for each rotation of the NLP sheet is supplied to the actuator 2 of the mechanical counter 1 according to the operating time.
Send it to and make it progress. This method has the advantage that the count value can be held even during a power failure.

[Problems to be solved by the invention]

In the conventional method, since the mechanical counters attached to each device are managed independently, the inspector at the time of regular maintenance must check each inspection item of each device with human eyes. Furthermore, since the reference values of the inspection items belonging to the same counter are not necessarily the same, human judgment is required to determine the necessity of replacement or replenishment of the tape, developer, toner, filter, or the like subject to the inspection items. , The inspector's operational and mental effort is large.

Therefore, it is conceivable to provide an electronic counter for each inspection item of each I / O under CPU control, count in a unit suitable for each, and automatically read them during regular maintenance inspection.

An object of the present invention is to automatically extract maintenance contents required for periodic maintenance and inspection of a plurality of I / Os under CPU control.

[Means for solving problems]

In order to achieve the above object, the regular maintenance and inspection item display device of the present invention is an input / output device (I / O) under the control of an information processing device (CPU).
Of the regular maintenance and inspection item, each unit is counted in a unit suitable for each item, and is reset after the maintenance is finished. A register for each item, a means for collating the accumulated count value since the reset with a preset reference value, and the collation With the display unit that displays the maintenance content for each inspection item from the result of 1., the maintenance content for each periodic maintenance inspection item that the count accumulated value exceeds the reference value is executed by the collating means during the periodic maintenance inspection. Is provided with a control means for automatically displaying on the display unit.

[Action]

With the above configuration, at the time of regular maintenance inspection, the value counted in the register for each inspection item of each I / O is compared with the preset reference value when the value accumulated at each inspection time is compared and exceeds the reference value. The object of inspection items is extracted, replaced, and replenished. This greatly simplifies the operation by the inspector.

〔Example〕

A Japanese line printer will be described below as an example of an input / output device to which the present invention is applied.

FIG. 1 is an explanatory diagram of the configuration of the embodiment of the present invention. In the figure, under the control of the CPU 11 of the processing device, a RAM 12 storing a program and a RAM 13 storing data are provided via a bus 15, and data is input by a keyboard (KB) 14 with a display (DPL). An external memory 17 is also provided via the communication control unit 16.

A Japanese line printer (NLP) 18 is connected to this bus 15 as an input / output device (I / O) 20, and outputs a drive pulse every time the paper drum for performing this printing makes one revolution.
Register 21 is counted. And CP during regular maintenance
The AND circuit 22 is turned on by the instruction from U11 to register 21.
Read the contents of, and the difference α between this count value and the last time
Is calculated, the count value after the replacement of the filter is accumulated, and the accumulated value is compared with the reference value stored in the RAM 13, and when the reference value is exceeded, the display (DPL) 1
The maintenance contents for each inspection item, such as the replacement of filters, etc., are displayed on the 4 above. Further, in order to cope with a power failure, a battery control unit 23 is prepared, and at least refreshing is performed to retain the stored contents.

FIG. 2 is a flow chart showing the operation of the embodiment of the present invention.

In the figure, after the start, the CPU 11 reads the NLP counter 21, obtains the difference α between the present value and the previous value, collates the value obtained by accumulating the α value every time since the previous reset with the reference value, and as a result, When the count value of the counter 21 exceeds the reference value, the maintenance contents of a plurality of items that require maintenance and inspection at that time, for example, replacement and replenishment of filters are displayed. Based on this, maintenance will be carried out for each item.

After this maintenance is completed, the counter is reset. Similar processing is performed for other inspection items, and the process ends.

FIG. 3 is a display example of the embodiment of the present invention, in which device names and maintenance contents at the time of regular maintenance and inspection are listed, and an inspector carries out maintenance based on this.

〔The invention's effect〕

As described above, according to the present invention, each I under CPU control is
A register is provided in each / O, the accumulated value of the count value is compared with the reference value, and the maintenance content for each inspection item is automatically extracted and displayed based on the result. At the time of regular maintenance and inspection, the inspector does not have to check the counter of each different device one by one, and does not have to bother with human judgment to compare with the reference value. , Only the regular inspection point prefecture items whose count value exceeds the reference value can be automatically extracted as items to be maintained, so it is possible to simplify the operation of the inspector and reduce the burden, and to prevent errors. Can be prevented.
