Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of intelligent temperature sensor system.
Detailed description of the invention
As it is shown in figure 1, a kind of intelligent temperature sensor system that Fig. 1 is the present invention to be proposed.
Reference Fig. 1, the intelligent temperature sensor system that the present invention proposes, including:
Temperature Prediction unit, accurate measuring unit, temperature display unit, control unit；
Temperature Prediction unit, for tentatively estimating the temperature of measurand, and sends out preliminary for temperature estimation results
Deliver to control unit；Described Temperature Prediction unit includes two sensor elements, and Temperature Prediction unit is to measurand
The preliminary estimation results of temperature is the meansigma methods of the detected value of above-mentioned two sensor element, by arranging two sensor elements pair
The temperature of measurand is tentatively estimated, and fundamentally ensure that the accuracy tentatively estimated of the temperature to measurand,
And then be conducive to controlling the simple eye temperature higher according to accuracy preliminary estimation results control accurate measuring unit work, help control
Unit processed selects suitable sensor element to detect the actual temperature of measurand.
Accurately measuring unit, for accurately measuring the temperature of measurand, and sends out temperature accurate results
Deliver to control unit；Described accurate measuring unit includes four sensor elements, respectively first sensor element, the second biography
Sensor component, the 3rd sensor element, the 4th sensor element；Control unit receives the tested right of Temperature Prediction unit transmission
After the preliminary estimation results of temperature of elephant, estimation results preliminary to said temperature is analyzed, and will tentatively estimate knot by said temperature
Fruit compares with the temperature cut off value of storage in control unit, determines that further according to comparative result being actually needed selection accurately measures
The quantity of unit inner sensor element, when temperature is higher or lower, control unit selects less sensor element, because
When temperature is higher or lower, temperature belongs to the temperature being unsuitable for needed for daily life, may belong to specific temperature environment, now
To the certainty of measurement of temperature without being accurate to the finest degree；When the preliminary estimation results of temperature is in moderate level, above-mentioned
Temperature range belongs to the conventional temperature in daily life, now higher to the certainty of measurement of temperature, because variations in temperature now
May have influence on next step operation of user, therefore control unit selects the more sensor element temperature simultaneously to measurand
Degree is acquired and averages, it is ensured that the certainty of measurement to the actual temperature of measurand, is conducive to helping user to tested
The analysis of object actual temperature.
Temperature display unit, communicates to connect with control unit；For showing the temperature of measurand that control unit sends
Information, user can watch the preliminary estimation results of temperature of measurand and temperature accurately to measure knot by temperature display unit
Really, beneficially user recognizes the actual temperature of measurand and takes next step measure；Further, temperature is passed through as user
When display unit watches the preliminary estimation results of temperature of measurand and temperature accurate results not to have difference, use can be reminded
Family is noticed that whether to exist the situation of accurate measuring unit inner sensor component wear, is conducive to reminding user to accurate measuring unit
The service life of interior sensor element checks, it is ensured that accurately measuring unit inner sensor element is in the shape that normally works
State, i.e. ensure that the certainty of measurement to measurand temperature.
Control unit, with Temperature Prediction unit, the communication connection of accurate measuring unit；Control unit receives Temperature Prediction list
After the temperature entry evaluation result of the measurand that unit sends, estimation results preliminary to said temperature is analyzed, will temperature
Preliminary estimation results T contains temperature cut off value T with control unit internal memory1、T2Compare, control accurately further according to comparative result
Measuring unit works, and calculates the actual temperature of measurand according to the temperature accurate results of accurate measuring unit；Its
Middle T1<T2；
As preliminary estimation results T of the temperature of Temperature Prediction unit≤T1Time, show that the temperature of measurand is relatively low, the most right
The certainty of measurement of measurand temperature requires higher, then control unit instruction controls first sensor element, the second sensor unit
Part, the 3rd sensor element work simultaneously, then the actual temperature of measurand is the flat of above three sensor element detected value
Average；Work as T1<T<T2Time, show the moderate temperature of measurand, now the highest to the certainty of measurement of measurand temperature, then control
Unit processed instruction controls first sensor element, the second sensor element, the 3rd sensor element, the 4th sensor element simultaneously
Work, increases the scope to measurand temperature acquisition, gathers the temperature of measurand from diverse location, and then by aforementioned four
The detected value of sensor element, as the actual temperature of measurand, has fully ensured that measurand actual temperature detects accurate
Property and effectiveness；As T >=T2Time, showing that the actual temperature of measurand is higher, one is relatively gone up in the now requirement to certainty of measurement
Situation is on the low side, then control unit instruction controls first sensor element, the second sensor element, the 3rd sensor element work simultaneously
Making, the actual temperature of measurand is the meansigma methods of above three sensor element detected value, it is to avoid the single temperature of use passes
Sensor component carries out the drawback causing certainty of measurement relatively low during temperature acquisition, is further ensured that and measures measurand actual temperature
Precision, user-friendly while ensure the accuracy of temperature acquisition, be conducive to next step operation for user to provide
Reference frame reliably.
The above, the only present invention preferably detailed description of the invention, but protection scope of the present invention is not limited thereto,
Any those familiar with the art in the technical scope that the invention discloses, according to technical scheme and
Inventive concept equivalent or change in addition, all should contain within protection scope of the present invention.
