Abstract
The marine radio calibration beacon refers to a radio frequency signal generator that can provide stable tracking signals for shipborne unified measurement and control equipment.It is generally installed inside sounding balloons or suspended at the bottom of drones.After flying to a certain height and distance,the shipborne unified measurement and control equipment conducts tracking tests on the beacon signal.The present marine radio beacons can only operate at one frequency point in the air.If multiple operating frequency points need to be calibrated,the multiple radio beacons need to be released repeatedly.Therefore,a peripheral frequency conversion control circuit for the calibration beacon has been designed.By connecting this circuit to the calibration beacon,releasing one beacon for multi frequency calibration can be fulfilled.In the frequency conversion circuit,a low power SCM STC89C52RC is used as the basic control unit,which achieves the function of sending multiple preset working frequency point information to the beacon in a predetermined frame format at a fixed time by combining a DC-DC voltage reduction module and a level conversion module.After more than ten maritime and aerospace measurement tests,the results show that the program controlled frequency conversion control circuit can operate stably and has high control accuracy,and it can save calibration time and budget.关键词
