Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 2 as can be known, the utility model capacitor C 1,2 are loaded on housing 3 inner belows, capacitor C 1,2 upper surfaces are coated with hotting mask heating plate 4, heat sensitive sensor 5 is fixed on a side of housing 3, capacitor C 1,2 join through lead and control circuit mainboard 6, capacitor C 1,2 central processor MCU that output signal on the control circuit mainboard 6 at housing 3 tops show signal by digital filtering and digital match by output terminal output and by digital display tube LED, heat sensitive sensor 5 is linked to the central processor MCU analog input end through filter resistance R, central processor MCU is carried out the AD conversion, and calculate, central processor MCU produces electric signal and starts or stops hotting mask heating plate 4.
The utility model adopts electric capacity, and the electrolyte in the electric capacity is a liquid, if environment temperature is low excessively, electrolyte solidifies easily even freezes, and can reduce transducer sensitivity and output accuracy.Therefore working sensor is had relatively high expectations to environment temperature.Adopted temperature maintenance technology to make sensor in certain low temperature range, can guarantee normal work.The utility model is the laying temperature sensor near sensitive components, gather the environment temperature that sensitive components is worked, through filtering and A/D conversion data are passed to central processor MCU, central processor MCU is calculated according to certain mode, the normal operating temperature range of data that draw and sensitive components compares, when going beyond the scope, central processor MCU can produce an electric signal and start the film heating plate, is used to improve its operating ambient temperature; When environment temperature was enhanced sensitive components normal working temperature scope, through the calculating and the judgement of central processor MCU, it can produce an electric signal once more and cut off the power supply of film heating plate.Utilize this mode to guarantee the operate as normal of sensor.
Because circuit part used multi-channel A/D signal, comprise the output of two sensitive components of X-axis, Z axle, and the output etc. that is used for the temperature sensor that temperature keeps, the real-time output of multi-channel A/D signal and conversion can produce digital noise; Simultaneously, X-axis, two axial switch transition of Z axle can produce bigger Wen Bo and interference.Will have influence on the output accuracy and the linearity of sensor like this.In data acquisition, utilize digital filtering and in the data output procedure, adopt Technology of Data Fitting, not only can improve sensitivity, precision and the maintenance linearity of sensor output, and reduced the design complexities of sensor hardware, and can reduce cost and reduced volume.Because the central processor MCU that this sensor adopted has the work dominant frequency of 33MHz, when data acquisition is carried out in the output of sensitive components, by software programming, give up the data that initial some collections are come in, and to after the valid data that collect carry out mode such as arithmetic mean calculating and carry out digital filtering, the data presented of once exporting of this sensor is to come out through 45 data computation that collect usually.Calculate in the output procedure at sensor, in order to protect just its linearity and precision, at timing signal the little unit of trying one's best is tested, the observation test data are divided into the multiple segment data group by linear consistent point of proximity, carry out the multiple segment data match then.So just improve the output accuracy of sensor, guaranteed linearity.
