Data Checkout of Intelligent Sensor in Distributed Remote Temperature Measurement System
Intelligent sensor DS18B20 is used in distributed remote temperature measurement system. This paper expounds the CRC generator realization principle of intelligent temperature sensor DS18B20. The method of CRC checkout is illustrated about 64-bit serial code reading of intelligent temperature sensor. When reading the temperature data, CRC checkout is also taken into account. The realization rule of CRC checkout for scratchpad is analyzed. The CRC realization program in intelligent temperature sensor based on AT89C51 is given out. The reading program of serial code with data checkout and CRC program based on single bus are designed in detail. This paper also analyzes Cyclic Redundancy Code and traditional error checkout. Data checkout is proved primely in distributed remote temperature measurement system.
