| titleOfInvention | A kind of digital constant temperature control circuit applied to moving base gravimeter |
| abstract | The present invention relates to a kind of digital constant temperature control circuit of moving base gravimeter, which is made of temperature measurement circuit, digital signal processing circuit, driving circuit and power supply circuit.Temperature measurement circuit is made of accurate reference voltage, bridge for measuring temperature, multi-channel switch, instrument amplifier, low-pass filter; digital signal processing circuit is made of A/D sampling A/D chip, dsp chip, fpga chip; driving circuit is made of optocoupler, protection diode, metal-oxide-semiconductor, adding thermal resistance and fan, and power supply circuit includes ± 15V module, 5V module, 12V module and 3.3V module.The present invention constructs bridge for measuring temperature using precision resister and platinum resistance, precision resister resistance value is selected with the resistance value of platinum resistance under target temperature value as reference, so that the measurement noise of bridge for measuring temperature is reached minimum when control temperature is close to target temperature value, realizes high-resolution temperature measurement. |
