The invention discloses a pneumatic massage control system for a seat, and the system comprises an independent air source which is connected with a main valve and an auxiliary valve through a common air path, forms a one-to-one correspondence relationship with the main valve, and is only controlled by the corresponding main valve; the main valve is in communication connection with the auxiliary valves and controls the main valve and the auxiliary valves to execute inflation and deflation according to the massage point position sequence; and the auxiliary valve only analyzes and executes the command of the main valve and feeds back working parameters of the auxiliary valve to the main valve. The main valve serves as a controller, the auxiliary valve serves as an actuator, and the technical problem that a single valve cannot drive enough massage air bags is solved. Moreover, when a plurality of valves work cooperatively, the main valve coordinates the massage point sequence of the air pump and the massage point sequence of each auxiliary valve as a whole, and the massage function of more than 20 massage points can be achieved. Due to the fact that the main valve and the auxiliary valve are communicated through the standard LIN protocol, the communication rate is 19.2 kbps, real-time interaction between the main valve and the auxiliary valve is guaranteed, the response speed is within 10 ms, and therefore the passenger side can have very smooth multi-point massage experience.
本发明公开了一种座椅气动按摩控制系统,包括:独立气源,其通过共用气路连接主阀和副阀,其与主阀形成一一对应关系,其只受对应的主阀控制;主阀,其与副阀通信连接,其根据按摩点位序列控制自身和各副阀执行充放气;副阀,其只解析并执行主阀命令,其反馈自身的工作参数至主阀。本发明将主阀作为控制器,将副阀作为执行器,解决了单个阀无法驱动足够数量的按摩气袋的技术问题。并且,在多个阀协同工作时,通过主阀统筹协调气泵和各副阀的按摩点位序列,能实现20个以上按摩点按摩的功能。由于本发明主副阀采用了标准LIN协议通信,通信速率19.2kbps,确保主副阀间实时交互,响应速度为10ms以内,因此乘客端会有非常流畅的多点按摩体验。
