Prediction type electronic thermometer circuit structure for realizing temperature compensation

Abstract

The invention relates to a predictive electronic thermometer circuit structure for realizing temperature compensation, which comprises a compensation module, a thermometer circuit and an LCD (Liquid Crystal Display) driving module, the thermometer circuit comprises a temperature measurement oscillating circuit and an actual measurement module, and the compensation module and the actual measurement module are connected in parallel between the temperature measurement oscillating circuit and the LCD driving module. The circuit structure respectively controls the switch-on and switch-off of the switch compensation module and the actual measurement module through combinational logic, and under the condition that the compensation module is switched off, the actual measurement module is switched on and outputs actual test data; and under the condition that the actual measurement module is disconnected, the compensation module is conducted, and a temperature value subjected to prediction compensation is output. The predictive electronic thermometer circuit structure for realizing temperature compensation is provided with two sets of counting systems, an actual measurement mode and a predictive mode can be selected, and production calibration is facilitated. The electronic clinical thermometer has a temperature compensation function and can realize a rapid and accurate temperature measurement function.

Description

technical field [0001] The invention relates to the field of electronic thermometers, in particular to a circuit structure of a predictive electronic thermometer that realizes temperature compensation. Background technique [0002] At present, the common thermometers mainly include mercury thermometers, electronic thermometers and infrared thermometers. [0003] Mercury thermometer is a traditional thermometer, which is cheap and convenient to use. Generally, it can be taken out after staying for about 5 minutes at the part that needs to be tested. When using the electronic thermometer, put the thermometer into the part that needs to be measured, and after about half a minute, you can take out the reading when you hear the buzzer alarm. There are also infrared thermometers, which take a shorter measurement time. Generally, the body temperature can be monitored in a few seconds. There are two types of contact and non-contact. Because infrared thermometers are expensive and ...

Problems solved by technology

In order to shorten the measurement time and achieve the effect of rapid temperature measurement, many merchants will try to choose a small stabilization time, so that although the measurement time is shortened, the measurement error will be relatively large
