The invention belongs to the technical field of aviation anti-icing and de-icing, and discloses a helicopter main blade heating control system based on serial port bus communication, which comprises an anti-icing and de-icing distribution box, a rotor anti-icing and de-icing controller, a main blade adapter, a main blade collector ring assembly and a main blade heating assembly, an RS422A bus is used for communication between the rotor anti-icing and de-icing controller and the main paddle distributor, the rotor anti-icing and de-icing controller sends atmospheric temperature data to the main paddle distributor, and the main paddle distributor judges a cold and hot mode and calculates the heating time of each main paddle partition; the main paddle distributor feeds back the heating state of each subarea of the current five main paddles to the rotor wing anti-icing and deicing controller through an RS422A bus; when the main blade is heated, the rotor wing anti-icing and de-icing controller collects a main blade three-phase induced voltage value sent by the anti-icing and de-icing distribution box and calculates a main blade three-phase heating current, so that whether a fault occurs in the heating process or not is judged. Compared with time sequence level, data of bus communication has check modes such as odd-even check and check, and the reliability of data transmission is improved.
本发明属于航空防除冰技术领域,公开了一种基于串口总线通讯的直升机主桨叶加热控制系统,包括防除冰配电盒、旋翼防除冰控制器、主桨适配器、主桨集流环组件和主桨叶加热组件;旋翼防除冰控制器与主桨配电器之间使用RS422A总线通讯,旋翼防除冰控制器将大气温度数据发送给主桨配电器,由主桨配电器判断冷热模式并计算每个主桨分区的加热时间;主桨配电器通过RS422A总线向旋翼防除冰控制器反馈当前5片主桨叶各分区的加热状态;主桨叶加热时,旋翼防除冰控制器采集防除冰配电盒发送的主桨三相感应电压值,并解算出主桨三相加热电流,从而判断加热过程中是否故障。相比于时序电平,总线通讯的数据有奇偶校验、和校验等校验方式,提高了传输数据的可靠性。
