The Design of Highly Precise and Intelligent Thermal ransmitter Based on Sigma-Delta ADC and CAN Bus

摘要：

The design pattern of intelligent thermal transmitter based on Σ- ΔADC and CAN bus is brought forward in this paper. Σ- ΔADC is a new type of A/D converter which includes signals amplifier circuitry and low pass filter circuitry inside, and its cost is low. So the Σ- ΔADC is very appropriate to thermal measurement; CAN bus is a kind of bus system whose protocol is open and it is widely applied to industrial fields. This paper states the design of hardware and software of intelligent thermal transmitter detailedly.
