Abstract
A singlechip nipple thermometer control device with extraposition A/D converter is provided, which comprises an A/D converter, a reset key, a singlechip and a LCD. The utility model is characterized in that: a resistance type probe and the singlechip are connected in the mode that the input end of the resistance type prove is connected the input end of the extraposition A/D converter; the output end of the extraposition A/D converter is connected to the I/O input end of the singlechip.
Description
Technical field the invention relates to a kind of clinical thermometer control device, and particularly a kind of single-chip microcomputer nipple thermometer control device of external A/D converter belongs to the application of singlechip technology in medical instrumentation.
Background technology generally adopts mercury clinical thermometer in order to the clinical thermometer of measuring oral cavity body temperature, because the thermometric time is longer, dangerous again, is unsuitable for the baby and uses in the oral cavity.
The purpose of summary of the invention the invention provides a kind of single-chip microcomputer nipple thermometer control device of external A/D converter.
The invention solves the technical scheme that its technical matters adopts: this device comprises external A/D converter, single-chip microcomputer and LCDs; Resistive probe, resetting strong with LCDs with the connected mode of single-chip microcomputer is: the input end of resistive probe is connected with external A/D converter input end, external A/D converter output terminal is connected with the single-chip microcomputer input end, resets to be good for to be connected with the single-chip processor i/o input end.The single-chip processor i/o output terminal is connected with the LCDs input end, and single-chip microcomputer is by the work of software-driven LCDs.
The resistive probe that the invention is installed in the nipple transmits the temperature data in tested baby oral cavity to external A/D converter, converting digital signal to by external A/D converter is connected with the single-chip microcomputer input end, the single-chip microcomputer input end drives LCDs, shows tested baby temperature.
The beneficial effect of the invention is: utilizing the baby that nipple is not had fear and reaches rapid thermometric purpose of safety, is the renewal product of traditional mercury clinical thermometer.As the human nature service of hospital, be widely used in baby's oral cavity temperature taking.
Description of drawings: accompanying drawing 1 is an embodiment schematic diagram of the present utility model.
Embodiment: consult accompanying drawing 1.The invention single-chip microcomputer is selected PIC16C57 for use.Resistive probe R is connected with external A/D converter AD558 input end, external A/D converter AD558 output terminal is connected with single-chip microcomputer input end I/O (1) I/O (2) I/O (3), I/O (4), I/O (5), I/O (6), I/O (7), I/O (8), the end of reset key K is connected with single-chip processor i/o (9), and be connected other end ground connection with positive source by resistance.Single-chip microcomputer PIC16C57 output terminal I/O (10), I/O (11), I/O (12), I/O (13), I/O (14), I/O (15) are connected with the input end of LCDs respectively.LCD is a LCD.Resistive probe transmits the temperature data in tested baby oral cavity to external A/D converter AD558, converts digital signal to by external A/D converter AD558 and is connected with the single-chip microcomputer input end, and the single-chip microcomputer input end drives LCDs, shows tested baby temperature.
Single-chip microcomputer PIC16C57 directly drives LCDs work by software, shows tested baby temperature.But by reset key K zero clearing.
