Abstract

The invention relates to a rotor speed monitoring processor, comprising a main control module, a power module, a base component and a cover component. The processor is characterized in that the main control module comprises a speed interface circuit, a discrete output drive circuit, a frequency-voltage conversion circuit, a DC output circuit, a speed comparison circuit, and a CPLD control circuit.The CPLD control circuit is respectively connected with the speed interface circuit, the discrete output drive circuit, the frequency-voltage conversion circuit, and the speed comparison circuit, andthe frequency-voltage conversion circuit is respectively connected with the DC output circuit and the speed comparison circuit. The rotor speed monitoring processor introduces the helicopter rotor speed magnetic sensor signal and the onboard power supply to the main control module and the power supply module respectively through the base component. The main control module collects the frequency signal of the speed magnetic sensor, and real-time converts all the collected frequency signals into analog signals and discrete signals for collection by on-board back-end equipment.

Description

technical field [0001] The invention relates to a rotor speed monitoring processor, in particular to a rotor speed monitoring processor which collects and judges frequency signals of a magnetic speed sensor in real time and outputs multiple discrete signals and analog signals. Background technique [0002] In the status monitoring of the rotor speed of the helicopter, the signal of the magnetic speed sensor is generally connected to the corresponding acquisition device for collection, and there is no special equipment for collecting the signal of the magnetic speed sensor. Due to the large number of equipment on the machine to collect the speed signal, the distribution is wide, and the collection and processing methods are different, the parameter values ​​​​of the same signal after collection are inconsistent, and even there are large errors; Abnormal condition of load impedance mismatch. Contents of the invention [0003] Purpose of the invention: [0004] Provide a ro...
