The analog signal output end of the temperature sensor is connected to the analog signal input end of the analog-digital converter, the digital signal output end of the analog-digital converter is connected with a first digital signal input end of the microcontroller, the digital signal output end of the microcontroller is connected to the LCD displayer, and the alarm signal output end of the microcontroller is connected to the alarm signal input end of the high-temperature alarm module, the digital signal output end of the signals of the input module is connected with a second digital signal input end of the microcontroller, and the digital signal end of the storage unit is connected with a third digital signal end of the microcontroller. Former measured temperature values can be stored in the novel electronic thermometer, and the novel electronic thermometer can give out alarm automatically when the measured value of the novel electronic thermometer is higher than a normal human body temperature setting value.
Description
Technical field
The invention belongs to field of thermometers, relate in particular to a kind of novel electron thermometer.
Background technology
Clinical thermometer is modal a kind of medical apparatus in clinical nursing activity, and the height of body temperature provides important information for the physiological status that the doctor understands the patient.In hospital and family, generally use ethanol (or hydrargyrum) thermometer to carry out take temperature.Traditional mercury-in-glass thermometer aborning, scrap all can cause the mercury pollution public hazards afterwards, measure body temperature need 5-6 minute, human eye judgement numerical value is inaccurate and be difficult to body temperature is carried out the monitoring of long-time continuous.How cost of manufacture is cheap, and convenient and safe medical apparatus and instruments improves diagnosis efficiency, alleviates the patient suffering, is the task of top priority of medical electronics design.
Along with the development of microelectric technique and information technology, various digital body thermometer designs continue to bring out, in the demand that meets in varying degrees clinical treatment.Digital clinical thermometer has the advantages such as volume is little, lightweight, easy to use, to measure short, reading no one directly perceived of waiting time be misjudge in comparison.There are two shortcomings in current thermometer great majority: first: thermometer does not have to store the last function of measuring temperature, to such an extent as to can not check the historical record of thermometer.Second: in take temperature, inconvenient reading, the patient, in measuring process, often measures a period of time and takes out and check lower measured value, see that whether the measured value of thermometer is higher than the normal body temperature value, had a strong impact on the accuracy of measuring and reduced the efficiency of surveying body temperature.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of novel electron thermometer, the temperature value of in the past measuring can be stored in thermometer, and when the thermometer measure value sets value higher than normal body temperature, automatic alarm.
Technical scheme: for achieving the above object, technical scheme of the present invention is as follows:
A kind of novel electron thermometer, comprise temperature sensor, analog-digital converter, microcontroller, LCD display, high temperature alarm module, memory element and input module; The analog signal output of described temperature sensor is connected with the input end of analog signal of analog-digital converter, the digital signal output end of described analog-digital converter is connected with a count word signal input part of microcontroller, the digital signal output end of described microcontroller is connected with LCD display, and the alarm signal output ends of microcontroller is connected with the alarm signal input of high temperature alarm module; The digital signal output end of the signal of described input module is connected with microcontroller two count word signal input parts, and the digital signal end of described memory element is connected with microcontroller three count word signal ends.
Wherein, described input module is keyboard.
Wherein, described high temperature alarm module is buzzer.
Beneficial effect: the present invention is connected with microcontroller three count word signal ends by the digital signal end of memory element, has realized the memory function of thermometer, can check the historical record of thermometer measurement of bldy temperature value; The alarm signal output ends of microcontroller is connected with the alarm signal input of high temperature alarm module, while having realized thermometer measure to improper body temperature, and the function of automatic alarm.
The accompanying drawing explanation
Accompanying drawing 1 is structured flowchart of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, a kind of novel electron thermometer, comprise temperature sensor 1, analog-digital converter 2, microcontroller 3, LCD display 4, high temperature alarm module 5, memory element 6 and input module 7; The analog signal output of described temperature sensor 1 is connected with the input end of analog signal of analog-digital converter 2, the digital signal output end of described analog-digital converter 2 is connected with a count word signal input part of microcontroller 3, the digital signal output end of described microcontroller 3 is connected with LCD display 4, and the alarm signal output ends of microcontroller 3 is connected with the alarm signal input of high temperature alarm module 5; Described high temperature alarm module 5 is buzzer.The digital signal output end of the signal 7 of described input module is connected with microcontroller 3 two count word signal input parts, and described input module 7 is keyboard.The digital signal end of described memory element 6 is connected with microcontroller 3 three count word signal ends.
During work, the patient puts into the measurement of bldy temperature place by the thermometer sensor 1 of thermometer, the critesistor of thermometer sensor 1 induction human body temperature, after the resistance value of reflection variations in temperature is converted into to the analog quantitys such as electric current or magnitude of voltage, be transferred in analog-digital converter 2, analog signal conversion becomes digital signal subsequently.The digital signal converted to transfers in microcontroller 3 again.After a period of time, microcontroller is contrasted this digital signal and specific setting value, and judgement, be stored to memory element 6, and measured value is presented in LCD display 4.
When temperature value that the patient measures, not in the body temperature range of set value at microprocessor 3, microprocessor 3 just can send alarm signal and control high temperature alarm module 5, automatic alarm.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
