Embodiment Construction
[0054] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0055] figure 1 It is the overall structure of the aero-engine intelligent pressure sensor. Combined with the distributed control system of the aero-engine, multiple functional units such as the signal processing unit of the intelligent pressure sensor, the intelligent calculation unit of the intelligent pressure sensor, the TTP / C communication unit of the intelligent pressure sensor and other circuits of the intelligent pressure sensor are designed respectively. In the hardware part, a second-order active filter is designed to filter and amplify the collected sensor signals. The AD7793 chip of ADI Company is used to collect the dual temperature sensor channels. The TTP / C bus controller adopts the AS8202NF chip provided by TTTech Company. The hardware part is mainly designed for the peripheral circuit of the TTP protocol controller, includi...
