Abstract

The invention discloses a sequence control circuit with paddle detection, and the circuit comprises a sequence control circuit and a feedback signal circuit, wherein the sequence control circuit is connected with the feedback signal circuit; the sequence control circuit is used for completing the control of conventional paddle partitions and providing excitation for the feedback signal circuit; the sequence control circuit is used for providing a sequence signal, the feedback signal circuit is used for receiving signal excitation provided by the sequence control circuit and feeding back the working condition of a partition in real time, the feedback signal circuit comprises a feedback signal module and a paddle switching module, and the feedback signal module is connected with the paddle switching module. The circuit is characterized in that a logic circuit is adopted to replace a single-chip microcomputer to achieve paddle switching, the tedious process of software product design and development is greatly simplified, development cost is saved, and product testability and reliability can be better improved.

Description

technical field [0001] The invention belongs to the technical field of electronic circuits and relates to a sequence control circuit with paddle detection. Background technique [0002] How to detect the blade heating circuit, that is, how to judge whether the anti-deicing heating resistance of each blade of the helicopter is intact, is the key technology to improve the testability of the anti-icing system. If you put measurement and control software in the blades, you often face problems such as insufficient installation space, increased weight of the blades, and inability to transmit signals. Therefore, a circuit that completely switches the blades in sequence through the hardware circuit is developed to realize the independent operation of a single blade. necessary. Contents of the invention [0003] The object of the present invention is to provide a sequence control circuit with blade detection, which can realize the control of blade switching and the isolated detect...
