Description
【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、計測機器における計測値の監視方法に関
する。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for monitoring a measured value in a measuring instrument.
従来、この種の監視は或る予め定められた規格値を上
下限設定値として行なわれるのが一般的である。Conventionally, this type of monitoring is generally performed using a predetermined standard value as an upper and lower limit set value.
しかしながら、このようにすると、例えば計測機器が
経年変化によりその機能が低下しても、常に同じ上下限
設定値にて監視されることになるため、必ずしも適切な
監視方法とは言い難い、という問題がある。However, in this case, even if the function of the measuring device is deteriorated due to aging, for example, it is always monitored at the same upper and lower limit set values, so that it is not always an appropriate monitoring method. There is.
したがって、この発明の課題はより適切な監視が可能
な方法を提供することにある。Therefore, an object of the present invention is to provide a method capable of more appropriate monitoring.
計測機器の計測値を逐次サンプリングしながら記録
し、その複数回のサンプリング値の互いに隣り合うもの
の差とその平均値とを求め、この差の平均値を所定値と
比較して計測機器の計測値を監視する。The measured values of the measuring equipment are recorded while being sequentially sampled, the difference between adjacent ones of the plurality of sampled values and the average value are obtained, and the average value of the difference is compared with a predetermined value to measure the measured value of the measuring equipment. To monitor.
サンプリング値の互いに隣り合うものの差とその平均
値、つまり計測値の変化率を監視することで、設備の異
常の徴候等を知り得るようにする。By monitoring the difference between adjacent sampled values and the average value thereof, that is, the rate of change of the measured value, it is possible to know signs of equipment abnormality or the like.

Is a recording unit (memory), 4 is a comparison unit, 5 is a setting unit (memory), 6 is a calculation unit, 7 is a setting unit, 8 is a notification unit including a display or printing device, etc., for monitoring power supply equipment. Here is an example.

警報または異常監視のための上下限設定値を、例えば次
式により求める。That is, the voltage or current of the input or output side of the power supply equipment 1 such as a UPS is measured by the measuring unit 2, and the result is sequentially recorded in the recording unit 3. The calculation unit 6 calculates upper and lower limit set values for alarm or abnormality monitoring from the measurement result, for example, by the following equation.
警報上限値＝（最大値−最小値）×レベル上限（％）/1
00＋平均値 警報下限値＝（最大値−最小値）×レベル下限（％）/1
00＋平均値 なお、最大値，最小値は計測値の或る一定期間におけ

告知部８によりその旨を告知するものとする。Alarm upper limit value = (maximum value-minimum value) x level upper limit (%) / 1
00 + average value Alarm lower limit value = (maximum value-minimum value) x level lower limit (%) / 1
00 + average value The maximum value and the minimum value indicate the maximum value and the minimum value of the measured value in a certain fixed period, and the average value indicates the average of these measured values. The obtained upper and lower limit set values are set in the setting unit 5, and are provided to the comparing unit 4, compared with the measured values from the measuring unit 2, and the measured values are monitored. Since such calculations are repeatedly performed sequentially and set in the setting unit 5, the upper and lower limit set values initially set as the standard values are sequentially updated,
Monitoring is performed based on the updated upper and lower limit set values. However, when the upper and lower limit set values thus obtained exceed the initial standard values, the performance of the device is not impaired by giving priority to the initial standard values. The set unit 7 has a level upper limit expressed by the above equation,
It is assumed that values such as a lower limit are set in advance. If the result of the monitoring based on the upper and lower limit setting values is out of the range, the notification unit 8 notifies the fact.
ところで、計測値の監視は上述のように通常はその上
下限設定値を用いて行なわれるのが普通である。しかし
ながら、このようにするとその異常を事前に検出するこ
とができない、という不都合が生じる。そこで、以下の
ようにすることが考えられる。By the way, monitoring of the measured value is usually performed using the upper and lower limit set values as described above. However, this causes a disadvantage that the abnormality cannot be detected in advance. Therefore, the following can be considered.

理を行なうものである。FIG. 2 shows an embodiment of the present invention for coping with the case shown in FIG. This is an example of monitoring a measurement value from, for example, the air conditioner 10. Further, a remote terminal 11 and a remote terminal receiving unit 12 are provided so as to be able to be remotely operated, and the following processing is performed by the arithmetic unit 6. .
すなわち、スイッチ13により操作員がその旨の指示を

可能となる。演算部６が所定以上の変化を検出すると、
演算部６は異常の徴候を告知するために、告知部８の例
えばブザーによりこれを告知する。That is, when the operator gives an instruction to that effect using the switch 13, the arithmetic unit 6 issues an instruction to the recording unit 3 and reads the latest multiple measurement data from there, and reads the measurement data between the measurement data adjacent to each other in time. And calculate the average value. Here, the reason for calculating the average value of the differences for a plurality of times instead of the difference between the two recent measurement data is as follows.
This is to avoid the influence of the temporary change. When the average value of the difference exceeds a preset value, it is considered that an unusual change has occurred in the air conditioner 10, so that it is possible to know the sign (trend) of the abnormality from this. Become. When the calculation unit 6 detects a change equal to or more than a predetermined value,
The calculation unit 6 notifies the sign of abnormality by, for example, a buzzer of the notification unit 8.
この発明によれば、計測値の変化率を監視すること

に対する予防のために役立てることが可能となる利点が
得られる。According to the present invention, by monitoring the rate of change of the measured values, it is possible to obtain an advantage that it is possible to know the sign of an abnormality of the equipment and to use it for prevention of failure or malfunction.
