Detailed description of the invention
For utility model content of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 to Fig. 3, a kind of electronic clinical thermometer, comprise temperature sensor, logic circuit, controller and intervalometer; Wherein:
Temperature sensor for measuring the body temperature of human body, in the preferred embodiment, employing be the infrared temperature sensor that Technical comparing is ripe, certainty of measurement is high;
Logic circuit receives the data that temperature sensor collects on the one hand, the data received are judged simultaneously, judge whether be in a default test specification in, in addition on the one hand, whether be in default test specification and export a two-position signal according to detection numerical value if detecting numerical value.Namely a high level and a low level is exported; In the preferred embodiment, described logic circuit comprises two digital comparators and a pulse generator; The signal output terminal of described temperature sensor is electrically connected with the signal input terminal of two digital comparators respectively, the comparison terminal of a digital comparator is provided with higher limit, the comparison terminal of another digital comparator is provided with lower limit, the lead-out terminal of two digital comparators is electrically connected with pulse generator by a logic " with door ", segment between higher limit and lower limit is default test specification, in the present embodiment, described higher limit is 42, and described lower limit is 35;
The data that controller one side reception temperature sensor collects, the count value of enumerator, on the other hand according to two data sequence received above, average is counted by statistical method, as everyone knows, arithmetic operator and logical operations are the basic functions of central processing unit, therefore the basic function just utilizing central processing unit to have herein realizes the object of this patent averaging, is not the improvement to central processing unit itself or its software algorithm; In this preferred embodiment: described controller comprises data storage, central processing unit and outut device; Wherein: the lead-out terminal of described temperature sensor is electrically connected with the I/O terminal of central processing unit by electrical switch; Described central processing unit is electrically connected with data storage, outut device respectively by data wire;
Intervalometer is electrically connected with temperature sensor, controller respectively; Wherein:
Described pulse generator, enumerator, controller are electrically connected successively; The lead-out terminal of described logic " with door " is electrically connected with controller by electrical switch.
Operation principle of the present utility model is: first by set timer parameter, such as every test in 5 seconds once, altogether tests 1 minute; Namely every 5 second intervalometer will send one-shot instruction to temperature sensor and controller, temperature sensor is tested once after receiving enabled instruction, then test result is sent to logic circuit and electrical switch; If test result is between 35-42, then logic circuit exports a high or low level, now electrical switch is in opening, test result is sent to central processing unit via electrical switch, simultaneously, pulse generator sends triggering command to enumerator under the effect of high or low level, and enumerator then pulse signals counts, and count results is sent to central processing unit; If test result is not between 35-42, then logic circuit exports a low or high level, now electrical switch is in closed condition, test result cannot deliver to central processing unit via electrical switch, simultaneously, pulse generator does not send triggering command to enumerator under the effect of low or high level, and enumerator does not now count; So circulated every 5 seconds said process, after one minute, central processing unit counts according to the count results of the test result sum counter received, concrete computational process is: first multiple test result is carried out summation operation, by the statistics number of summed result divided by enumerator after calculation, average can be counted out.Finally export.Obviously, the method of repeated detection averaging is more common in physical quantity process, and this method, compared with traditional single measurement, can reduce the impact that uncertain factor produces to greatest extent, the credibility of test result can be improved, namely improve the precision of test.
In above-mentioned specific embodiment: described outut device is the one in touch screen or display.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to this utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
