The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
Referring to Fig. 1 and Fig. 2, the utility model fuel temperature measurement spoon, it comprises a spoonful body, is provided with a temperature sensor, power supply, and carries out analog-to-digital conversion and data and handle and calculate the control circuit of temperature value and the temperature display of a video data in the spoon body; Described temperature sensor, power supply and temperature display all are connected with control circuit, by temperature sensor measurement oil temperature, the temperature information of measuring are fed back to controller, show the temperature of measuring by temperature display then.
Referring to Fig. 4 to Fig. 6, described control circuit comprises power supply and reset circuit, single chip machine controlling circuit and ISP download circuit; Described power supply and reset circuit all are connected with single chip machine controlling circuit with the ISP download circuit.In power supply and reset circuit, be responsible for electric power starting and shutoff by commutator K2, be provided with a single-chip microcomputer at described single chip machine controlling circuit, this single-chip microcomputer is U3 MCU control chip Atmega8 in the circuit, and carry 10 AD analog-digital converters, sensor signal is input to 26 pin (ADC3) of U3 MCU control chip Atmega8 through the modulate circuit signal, MCU carries out analog-to-digital conversion, converts carrying out gamma correction by interpolation method, finishes the conversion of temperature.
Referring to Fig. 3, this temperature sensor can adopt NTC temperature sensor or thermocouple temperature sensor, in the present embodiment, on the circuit of temperature sensor, use the Pt100 sensor of three-wire system, utilize the typical application circuit of bridge-type thermometric, temperature-measurement principle: circuit adopts TL431 and potentiometer VR1 to regulate the reference power source that produces 4.096V; Adopt R1, R2, VR2, Pt100 to constitute measuring bridge (R1=R2 wherein, VR2 is 100 Ω precision resistances), when the resistance value of the resistance value of Pt100 and VR2 is unequal, the pressure difference signal of a mV level of electric bridge output, this pressure difference signal amplifies the voltage signal of back output expectation size through amplifier LM324, and this signal can directly connect the AD conversion chip.
R3=R4, R5=R6, multiplication factor=R5/R3 in the differential amplifier circuit, amplifier adopts single 5V power supply.
