Abstract
The invention discloses a DSP-based human body temperature measurement system, which comprises a DSP controller, an infrared temperature measurement probe, an A/D converter, a temperature detection circuit, an LED display and an execution unit. The infrared temperature measurement probe is respectively connected with the input end of the temperature detection circuit and the input end of the A/D converter. The output end of the temperature detection circuit and the output end of the A/D converter are respectively connected with the input end of the DSP controller. The output end of the DSP controller is respectively connected with the LED display and the input end of the execution unit. The output end of the execution unit is connected with the input end of the temperature detection circuit. The system can be used for conveniently, quickly and accurately measuring the temperatures of human bodies or the surface temperatures of other objects.
Description
Technical field
The present invention relates to a kind of human body temperature measuring system, specifically relate to based on DSP human body temp measuring system.
Background technology
Body temperature is the essential characteristic of human life activity, is also to observe one of whether normal important symbol of function of human body.At present, the most popular mercury clinical thermometer of people is according to the character of expanding with heat and contract with cold of mercury with gradient of temperature, temperature value is judged by reading scale value, but mercury clinical thermometer will contact with the measured in use, and often to wait for the longer time, fully be heated to allow it, when also mercury being got rid of again in mercury bubble after measurement terminates, because mercury bubble is what to be made up of very thin glass, be easy to fragmentation, add that mercury vapour has extremely strong toxic action to human body, there are major safety risks.Along with the demand of medical development, under many circumstances, mercury clinical thermometer is own through can not meet fast and thermometric requirement accurately, so in order to the needs adapting to China's medical development, effectively carry out the temperature survey under particular surroundings, thus the propagation of effectively Control and prevention (such as first stream, SARS etc.) special disease, be badly in need of a kind of thermometric speed of design fast, the temperature measuring equipment that accuracy rate is high.
Summary of the invention
The technical problem to be solved in the present invention is to provide based on DSP human body temp measuring system, can realize the accurate measurement conveniently to human body temperature or other body surface temperature.
Based on DSP human body temp measuring system, comprise dsp controller, infrared temperature probe, A/D converter, temperature sensing circuit, light-emitting diode display and performance element, described infrared temperature probe connects the input end of temperature sensing circuit and the input end of A/D converter respectively, the output terminal of described temperature sensing circuit and the output terminal of A/D converter access the input end of dsp controller respectively, the output terminal of described dsp controller connects the input end of light-emitting diode display and performance element respectively, and the output terminal of described performance element connects the input end of temperature sensing circuit.
Further, also normal open switch is connected with between the output terminal of described infrared temperature probe and the input end of A/D converter.
Further, described A/D converter is built-in with operational amplifier.
Further, the output terminal of described dsp controller is also connected with reset circuit.
Beneficial effect of the present invention is: when needs are to human body or body surface thermometric, press normal open switch, after infrared temperature probe receives the infrared ray that human body sends, one tunnel is detected through excess temperature detection circuit, and another road is sent to display unit and demonstrates temperature reading after amplification, filtering, A/D conversion after dsp controller carries out analyzing and processing to measured signal; If the data that the data by analysis after process and temperature sensing circuit detect are inconsistent, then alarm is reported to the police, and comes again to detect through performance element simultaneously, until show correct temperature; Achieve the accurate measurement conveniently to human body temperature or other body surface temperature.
Accompanying drawing explanation
Fig. 1 is for the present invention is based on DSP human body temp measuring system structured flowchart.
