The invention belongs to the technical field of ice prevention and removal, and relates to an ultrasonic icing detection circuit. The system comprises a DSP, a transmitting circuit, a transmit-receive isolation circuit, a receiving circuit, a power supply module and a bus output. The transmitting circuit is composed of an excitation circuit and a tuning matching circuit. The receiving circuit is composed of a pre-amplification circuit, a high-speed ADC, a clock control circuit and a high-speed storage circuit. Compared with a common icing detection device which extends out of the surface of the airplane, the ultrasonic icing detection part which is flush with the surface of the airplane has the advantages that the adaptability to various different airplane types and environments is improved, the aerodynamic configuration of the airplane is not influenced, and the performance of the airplane is also ensured; the ultrasonic icing detection control part is installed in the airplane and is less affected by the external environment of the airplane. Aiming at an aircraft which develops rapidly at present, the device has the characteristic capability which is not possessed by a common icing detection device, and meets the requirements of a new-generation aircraft.

    本发明属于防除冰技术领域,涉及一种超声波结冰探测电路。其包括:DSP、发射电路、收发隔离电路、接收电路、电源模块及总线输出组成。所述发射电路,由激发电路和调谐匹配电路组成。所述接收电路,由前置放大电路、高速ADC、时钟控制电路和高速存储电路组成。通过与飞机表面平齐安装的超声波结冰探测部分,相对于伸出飞机表面安装的普通结冰探测装置,提高了对各种不同机型和环境的适应性,且不会对飞机的气动外形产生影响,也保证了飞机的性能;超声波结冰探测控制部分则安装在飞机内部,受飞机外部环境影响较小。针对目前迅速发展的飞行器,本发明具备普通结冰探测装置没有的特性能力,且满足新一代飞行器的要求。
