BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facility device monitoring apparatus, and more particularly, to a facility device monitoring device that is suitable for predicting a failure of the facility device by monitoring the number of times the facility device has been operated and the time period. Regarding the device.

2. Description of the Related Art Conventionally, for example, JP-A-62-172268.
As described in Japanese Patent Publication, there is proposed a facility device monitoring device that integrates the number of times the facility device is operated and the time, and outputs an immediate alarm when the integrated value exceeds a preset upper limit value. ing.

FIG. 3 is a block diagram showing a conventional monitoring device of this type, and FIG. 4 is a flowchart showing the processing procedure of the monitoring device of FIG. The monitoring device 1 shown in FIG.
A processing device 3 for processing a signal input to the input device 2, a display device 4 for displaying a processing result by the processing device 3, and an alarm output for outputting an alarm based on the processing result by the processing device 3. It comprises a unit 5 and an operation input device 6 for inputting an operation command to the processing device 3.

The above-mentioned input device 2 is connected to the equipment 7, and the operation signals and failure signals output from the sensors 8 and 9 of the equipment 7 are input. The processing device 3 integrates at least one of the number of times of operation and the operating time based on the operation signal and stores the integrated value, and determines whether the integrated value exceeds a preset upper limit value. The display unit 4 displays the operating state of the equipment 7 in a normal state, and outputs an alarm by the alarm output unit 5 when an abnormality occurs. Further, according to an operation command input via the operation input device 6, the display screen of the display device 4 is switched or the alarm output of the alarm output unit 5 is stopped by the control of the processing device 3.

In this conventional monitoring apparatus 1, the equipment 7 is monitored based on the operation signal from the sensor 8 in accordance with the processing procedure shown in FIG. That is, when the operating signal from the sensor 8 of the equipment 7 is input to the input device 2 in step S1, the operating time and the operation of the equipment 7 are operated by the arithmetic unit 10 of the processor 2 based on the operation signal in step S2. At least one of the numbers of times, for example, operating time is calculated, and the integrated value of this operating time is stored. Next, as step S3, the determination unit 11 of the processing device 2
Thus, it is determined whether or not the integrated value of the operating time exceeds a preset upper limit value, and if the integrated value of the operating time exceeds the upper limit value, an alarm is output from the alarm output unit 5 in step S4. On the other hand, if the integrated value of the operating time does not exceed the upper limit value in step S3, the procedure returns to step S1 and steps S1 to S3 are repeated.

[0006]

By the way, in the above-mentioned conventional monitoring apparatus 1, when the integrated value of the number of times of operation of the equipment 7 or the operating time exceeds the preset upper limit value, an immediate alarm is output. However, there is a case where the equipment 7 does not always have a failure, and only the fact that maintenance and inspection of the equipment 7 is required in the near future may be called. However, for example, when the above-mentioned alarm is output at night or on holidays when the administrator in charge of maintenance of the equipment 7 is not working, go to each time to check the content of this alarm and stop it. There is a concern that it will impose a considerable burden on the above manager.

Further, when the manager is taking a nap due to the night duty at night, the above-mentioned alarm output causes the manager to wake up and respond. However, there is a concern that the administrator may mistakenly respond to an abnormal situation in which an alarm is output.

The present invention has been made in view of the actual situation in the prior art as described above, and an object thereof is to reduce the load on the maintenance manager of the equipment and to make the maintenance manager erroneous to the abnormal situation of the equipment. An object of the present invention is to provide a monitoring device for facility equipment that can reliably deal with the problem.

[0009]

In order to achieve this object, the present invention provides an arithmetic unit for accumulating at least one of the number of times of operation and the operating time based on an operation signal output from equipment and storing the integrated value. In a monitoring device for equipment, which has a determination unit that determines whether the integrated value exceeds a preset upper limit value, and an alarm output unit that outputs an alarm indicating that the integrated value exceeds the upper limit value, An output control unit that outputs the alarm from the alarm output unit only during a set predetermined time period is provided, and the operation of the alarm output unit is prohibited during a time period different from the predetermined time period.

In the present invention thus constituted, the alarm output section is activated by the control of the operation control means when the preset predetermined time zone is reached, while the alarm output section is activated in the time zone different from the predetermined time zone. Since the operation of the output unit is prohibited, the alarm output from the alarm output unit can be limited to a predetermined time period, for example, only during the daytime on weekdays, that is, the above-mentioned alarm output can be avoided at night or on holidays. Therefore, since the maintenance manager can carry out the work for the abnormal situation where the alarm is output at a convenient time, the burden on the maintenance man of the equipment can be reduced, and the maintenance work can be performed by the maintenance manager. You can do it without mistakes.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a monitoring device for facility equipment of the present invention, and FIG. 2 is a flowchart showing a processing procedure of the monitoring device of FIG. In FIG. 1, the same components as those shown in FIG. 3 described above are designated by the same reference numerals.

The monitoring device 1A of this embodiment shown in FIG.
Compared with the conventional device shown in FIG.
The main difference is that an output control unit 12 for outputting an alarm from the alarm output unit 5 is newly provided only in a preset predetermined time period, for example, a part of the preset time period. The configuration is basically the same.

In this embodiment, the equipment 7 is monitored based on the operation signal from the sensor 8 according to the processing procedure shown in FIG. That is, the procedure S
When the operation signal from the sensor 8 of the equipment 7 is input as 11 by the input device 2, at step S12, at least one of the operation time and the number of times of operation of the equipment 7 based on the operation signal by the calculation unit 10, for example, the operation The time is calculated and the integrated value of this operating time is stored. Next, in step S13, the determination unit 11 determines whether the integrated value of the operating time exceeds the preset upper limit value.
At this time, if the integrated value of the operating time exceeds the upper limit value, it is determined in step S14 whether it is a preset period, and the process waits until that period. Next, when it is a preset period, it is determined whether or not it is a preset time period as a step S15, and after waiting until the time period comes, an alarm is output from the alarm output unit 5 as a step S16. On the other hand, if the integrated value of the operating time does not exceed the upper limit value in step S13, the process returns to step S11 and steps S11 to S13 are repeated.

In the embodiment configured as described above, the alarm output from the alarm output unit 5 can be limited to a part of a preset time period, for example, only during the daytime on weekdays, that is, at the nighttime or on holidays. Since the output can be avoided, the burden on the maintenance manager of the equipment 7 can be reduced, and the maintenance manager can reliably handle the abnormal situation without making an error.

In this embodiment, the above period is set to 1
It can be set on a calendar day of the year or a day of the week, and other periods may be set according to the operating conditions. Further, in the present embodiment, only the operating time of the equipment 7 is calculated based on the operating signal, but the number of times of operation may be calculated instead of this operating time. Both the number of times of driving may be calculated.

[0016]

Since the present invention is configured as described above, the maintenance manager of the equipment can avoid the alarm output during inconvenient times, for example, on holidays and at night, and therefore the burden on the maintenance manager. It is possible to reduce the problem and surely respond to the abnormal situation of the equipment without making a mistake.
