摘　　要：提出了利用边折叠算法对基于光温耦合的二氧化碳调控模型进行简化的方法,首先利用MATLAB软件重新塑造基于光温耦合二氧化碳调控模型的三维图形,对该三维图形所对应的一部分特定的点进行数据采集和处理;然后采用边折叠算法,以平面近似代替曲面的方法,对该调控模型进行简化;最后将简化后的模型与原模型所得的二氧化碳饱和值进行对比,并且在Keil C51软件环境下对简化后的模型进行仿真。结果表明:简化后的模型所求得的值与原模型计算值的相对误差不超过3%,误差在允许的范围内;该模型在单片机上的运行速度提高了35.5%,内存空间占有量减少了23.1%,且计算精度满足实际要求。CO2 mathematical model coupled with light intensity and temperature is complex,which reduces it’s running speed on microcontroller.In order to solve the above problems,an edge reduction algorithm is adopted to simplify the model in this paper.Firstly,3D graph of CO2 control model is reconstructed by MATLAB software,and data of selected points in the 3D graph is collected.Then,the CO2 control model is simplified by using multiple planes to replace the curved surface approximately,namely,the edge reduction algorithm.Finally,the simplified CO2 control model is operated in Keil C51 and results are compared with that from the original model.It indicates that the simplified model occupies less memory space by 23.1%and it’s running speed has been increased by 35.5%.While deviation of the results between the simplified model and origin model can be limited in 3%.The calculation accuracy meets the actual requirements.
