Electronic thermometer, electronic temperature measuring system and automatic reading method of mercury thermometer

Abstract

The invention proposes an electronic thermometer, comprising: a mercury thermometer and a housing; the bottom of the mercury thermometer is a metal probe and a mercury ball, the middle part is a cylindrical clamping area, and the upper part is a cube-shaped data readout area. There is a light guide groove in the center of the four sides of the area. The light guide grooves are opposite to each other and in a straight line. The width of the light guide groove is smaller than the diameter of the mercury column; A bar-shaped light source is set, and an optical fiber array is set at the position opposite to the bar-shaped light source on the other side of the side wall of the housing; each phase in the optical fiber array has one end stuck in the light guide groove, and the other end connected to the The control terminal of the phototransistor, the collector of the phototransistor is connected to the power supply terminal, the emitter is connected to the ground potential through a resistor, the common end of the emitter of the phototransistor and the resistor is connected to the input terminal of the decoding circuit, and the decoding circuit The output terminal is connected to the digital display circuit.

Description

technical field [0001] The invention relates to the field of daily necessities, in particular to an electronic thermometer, an electronic temperature measuring system, and an automatic reading method for a mercury thermometer. Background technique [0002] Although the measurement accuracy of existing electronic thermometers is getting higher and higher, the accuracy of measurement can never surpass the traditional mercury thermometers. Moreover, the price of electronic thermometers is dozens of times or even hundreds of times that of mercury thermometers. Unable to popularize. [0003] In clinical application in hospitals, nurses are generally used to distribute mercury thermometers to patients, and then nurses manually count the temperature of each patient, which is low in work efficiency and increases the workload of nurses. Temperature data time lag. [0004] Therefore, how to obtain a thermometer with high measurement accuracy, low cost and fast statistical speed is a...
