摘要结合嵌入式系统BL2100 的优点,从电极的工作原理出发,对不具备温度补偿功能的溶氧变送器进行了软件温度补偿。试验结果表明,采用软件温度补偿的溶氧测量值可以达到与METTLER - TOLEDO 溶氧变送器相近的效果,从而证明了该方法的有效性。 关键词溶解氧温度补偿嵌入式系统 Abstract Combining with the advantages of embedded system BL2100 and based on the operational principle of electrode,temperature compensation is implement by software for dissolved oxygen transmitter of which the function of temperature compensation in not offered by itself. The experiments result show that the result obtained by software compensation for DO values can reach the same level provided by METTLER - TOLEDO dissolved oxygen transmitter, thus the effectiveness of this method has been proven.
