処理する測定情報処理装置に関するものである。Detailed Description of the Invention Background of the Invention A Technical Field The present invention relates to a measurement information processing device that can be used for temperature measurement, etc., and particularly to a measurement information processing device that corrects measurement information input from a detection means according to the characteristics of a detection element. The present invention relates to a measurement information processing device.
Ｂ 先行技術との問題点

すれば計測誤差を生じ、正確な計測は不可能であ
る。B. Problems with the prior art A processing device that processes measurement information needs to detect measurement information of the part to be measured. For example, when detecting the temperature of a living body, a thermistor is often used as a temperature detection element. However, this type of detection element has variations in measured values/output characteristics (for example, temperature resistance characteristics, etc.), and if used as is, measurement errors will occur, making accurate measurement impossible.

しかし、前者の場合には歩留りが悪くなり、計測

には他の部品を付加し、調整を施すのに困難を伴
う場合が多い。 If there are variations in the characteristic values of the detection elements,
Sort by characteristic value and use only those whose measurement error due to characteristic value variation is within the allowable range, or discard the others, or add other parts to the detection element to compensate for characteristic value variation. Temperature measurements are performed by making the output characteristics of measurement probes uniform and making them compatible by making adjustments.
However, in the former case, the yield will be poor and the price of the measurement probe will be high. Furthermore, in the latter case, it is often difficult to add other parts and make adjustments.

がある。 Furthermore, compensation information for characteristic values is recorded on the probe in accordance with the characteristics of the probe, and this code is read and input to a microcomputer using a digital switch to compensate for characteristic values (Japanese Patent Application Laid-Open No. 59-1999). -40113) and compensation data corresponding to the probe characteristics are stored in the memory on the probe side.
A device that electrically reads this compensation data and compensates the characteristic value on the measurement circuit (Japanese Patent Laid-Open No. 127119/1983)
There is.

な原因となつていた。 However, the former has problems with operability because it is input using a digital switch, while the latter uses electrical readout using a connector pin, so compensation errors due to poor contact can lead to measurement errors, and aging is always a problem. It has become a problem. In particular, when used in medical testing equipment, etc., the salt concentration of the liquid that comes into contact with the connector part is comparable to that of physiological saline, so the contained salt impairs the electrical conductivity of the connector pins, causing This was a major cause of defects.
