The proposed system uses an ultrasonic module interconnected to the microcontroller of the 8051 family to detect the object of the missile. An ultrasonic transducer comprising a transmitter and a receiver is used in the same module. The ultrasonic transducer produces sound waves. The transmitted sound waves are reflected back from the object and received by the transducer again. The total time taken from the sending of the waves to its reception is calculated taking into account the speed of sound. The distance is then measured and displayed on a liquid crystal display connected to the microcontroller. When the microcontroller receives the signal from the ultrasonic receiver, it activates the door gun by firing the MOSFET door through a transistor or relay. The sensor is mounted on the antenna and is rotated and controlled by the stepper motor through 360 degrees. If there are any targets within the detection range, the application will activate the launcher to the nearest detected target and fire. The antenna is rotated and controlled by the motor step by step by an axis and also with another axis it turns upwards and downwards the directions towards the missile object simultaneously . The tank vehicle is equipped with another microcontroller for the movements of the vehicle control actions sent and received by the key panel via the zigbee wireless communication. The programs for the 8051 family microcontroller are written by integrated C programming using the kiel software.
Avoiding collisions is a crucial problem in most transportation systems, as well as in many other applications. The task of a collision avoidance system is to track potential collision risk objects and determine any action to avoid or mitigate a collision. This thesis presents a theory for monitoring and decision making in collision prevention systems. The main focus is how to make decisions based on uncertain estimates and the presence of multiple obstacles. A general framework is proposed to deal with nonlinear dynamic systems and arbitrary noise distributions in collision avoidance decisions. Some novel decision functions are also suggested. In addition, performance assessments are presented using simulated and experimental data. Most of the examples in this thesis are automotive applications. A driving application for the work presented in this thesis is an automotive emergency braking system. This system is called a collision brake attenuation system (CMbB). Its aim is to mitigate the consequences of an accident by applying the brakes once the collision becomes inevitable. It is estimated that a CMbB system that provides a maximum collision speed reduction of 15 km / h and a reduction of the average speed of 7.5 km / h reduces all injuries, classified as moderate and fatal, for subsequent collisions in 16%. Since the rear-end collision corresponds to approximately 30% of all accidents, it corresponds to a 5% reduction for all accidents. The evaluation includes simulation results, as well as two demonstration vehicles, with different sensor configurations and different decision logic, which perform autonomous emergency braking.
