C8051F02X在飞机加油设备中的应用

Application of C8051F02X in Helicopter Refueling Unit

采用C8051F02X的飞机加油设备动态监控系统由压力与流量传感器、固态继电器和光电隔离器等组成。单片机通过压力传感器对压力采样,当压力超过安全设定时,自动关闭电机和控制阀,停止加油,对加油系统和飞机进行安全保护。该系统硬件含输入、输出及人机接口三部分,单片机内部基准电压则分别为A／D和D／A转换器提供基准电压。

The dynamic detection and control system based on C8051F20X MCU for helicopter refueling unit consists of pressure sensor, flow sensor, solid state relay and photodiode insulator. The pressure of pressure sensor was sampled with CS051F02X MCU. If the pressure of the system is higher than presetting, the motor and control value are turned off in order to ensure safety of helicopter and refueling unit. The system hardware is composed of input, output and man-machine interface. The reference voltage of A/D and D/A converters is provided by reference voltage of C8051F20X itself.
