摘要
针对危化环境中车辆驾驶舱内空气质量自适应控制的需求,采用了控制风机进气形成稳定超压保证空气来源单一性的方法,设计出一种基于MSP430的空气质量自适应测控系统。创新性的利用了PWM(脉冲宽度调制)控制技术结合模糊PID算法来合理驱动风机形成了完整的气压闭环测控系统使系统可以在极短时间建立起稳定的超压。系统在实验舱进行多次验证实验,获得了可靠的数据,验证了其方法,这种通过数字化调节气压的方法在工程控制方面具有重要意义。
Aiming at the requirement of air quality adaptive control in dangerous environment vehicle cockpit,an air quality adaptive measurement and control system based on MSP430 is designed by using the method of controlling the air inlet to form a stable overpressure to ensure the gas source singularity.Innovative use of PWM control technology combined with fuzzy PID algorithm to drive the fan to form a complete closed-loop pressure monitoring and control system allows the system to establish a stable overpressure in a very short period of time.In the experimental chamber for many verification experiments to access reliable data and verify the method,the system through the digital method of regulating pressure in engineering control is of great significance.
