IMPLEMENTATION OF LOW COST AERIAL TARGET DETECTION BY USING PIC MICROCONTROLLER - Tapa blanda

Sinopsis

This suggested device is equipped with the aid of ultrasonic sensors to detect the target (missile, aircraft, drones etc.) approaching and automatically kill it. The ultrasonic transducer is rotated at 360 degrees and consists of a transmitter and a receiver. The sound waves are emitted from the transducer and the transducer receives them again from the target. The ultrasonic transducer is linked to the microcontroller of the PIC. When the target is recognized within the detection range, the signal is received by the microcontroller. On the microcontroller, the software assigned will move the launching application to the degree detected and aim towards the target. This proposed device uses an ultrasonic module connected to the 8051 family of microcontrollers. An ultrasonic transducer consisting of a receiver and a transmitter is used. The waves transmitted are reflected back from the object and are again received by the transducer. The cumulative time taken from sending to receiving the waves is determined by taking the sound velocity into account. The distance is then determined by a program running on the microcontroller and displayed via wireless communication on a liquid crystal display screen interconnected to the microcontroller.

The circuit is used to receive 40 KHz reflected signals from the missile object, to feed them to the microcontroller program and to turn on the required load while the microcontroller is running the program. When the microcontroller receives the signal from the ultrasonic receiver, the door gun is triggered through a transistor or relay by triggering the MOSFET gate. The sensor is mounted on the antenna and is rotated and operated by a 360-degree stepper motor. The program will move the launcher to the nearest detected target and fire if there is any target inside the detection range.
