Change-?-type Drone Remote Control Receiver Circuit Analysis And Improvement Of Electromagnetic Compatibility

With the rapid development of electronic technology in the military field in the military wireless remote control model aircraft drone technology has developed very rapidly,and constantly upgrading,focusing on electronic devices is particularly evident on the expression of various components,the degree of system integration increasingly.The higher the transmission power is growing,resulting in the high-frequency harmonics caused by the electromagnetic compatibility problems become more prominent,and military drones in the development of new or improved production process that,due to the increasing of its new features,the circuit further complicated design requirements,internally generated a lot of unforeseen electromagnetic interference,the drone of the debug and test,or even result in damage to onboard equipment,has seriously affected the normal military training tasks.Therefore,how to suppress interference and ensure the normal operation of airborne equipment,is of great significance.In response to these problems,we use a combination of two commercial software approach,using the military to change the method of field-I-type drone remote control receiver circuit simulation of electromagnetic compatibility problems and make improvements.The main contents include:First,the electromagnetic compatibility of the basic concepts and principles of environmental electromagnetic compatibility,interference and transmission elements,the measures to achieve electromagnetic compatibility means of interpretation and clarification.Followed by a brief introduction to change-I-type drone remote control system works,among which are: the principle of remote control transmitter components and hardware design,composition and principles of remote control receiver hardware design.Then change the-I-type drone remote control receivers as research subjects,mainly through internal and external equipment,the interference generated a detailed analysis of the mechanism and identify measures to suppress interference.In particular,the source of electromagnetic interference have a clear understanding of electromagnetic interference into the path clear understanding of the EMI-sensitive receiver circuit protection.Finally,change-I-type drone remote control receiver circuit,high frequency interference caused by electromagnetic field simulation analysis of the compatibility issues,application software Protel 99 SE schematic drawing board and produce board map,generated in the software Ansoft Designer circuit simulation model,respectively,under different conditions to simulate the circuit board obtained simulation results,obtained through the EM near-field distribution of the comparison to find the best design to achieve optimal improvement.At the end of the whole article made a summary.
