Pest Protection Of Transmission Lines

In order to solve the problem of bird pest control on transmission lines,this paper deeply analyzes the causes of bird damage and the common management measures and technical measures for bird protection of transmission lines.The status of the device of driving birds common transmission line at home and abroad was described in detail,and the advantages and disadvantages of various types of bird repellents were comprehensively analyzed.Based on the current management measures for protection against bird damage on a single transmission line,a comprehensive set of integrated bird protection management measures has been innovatively designed to provide more effective protection against bird damage.In this paper,based on the bird’s ultrasound tympanic membrane vibration caused by20 kHz ~ 80 kHz larger,based on AT89C2051 microcontroller designed a new type of photoelectric induction ultrasonic bird repellent.The related peripheral circuits of the device of driving birds,including the ultrasonic generation unit,under-voltage protection and photoelectric detection circuit,are all based on the design of the AT89C2051 main microcontroller.Ultrasonic generation unit can randomly generate a kind of ultrasonic wave between 20kHz~80kHz,which can effectively solve the problem of adaptability of birds.The built-in photoelectric sensor of the bird repellent in this article can detect the activities of nearby birds from different angles under natural light,and has strong anti-interference ability.In this paper,the battery is used to power the device of driving birds circuit.The solar panel charges the battery,saves energy,and effectively solves the power module’s cost restriction on the device of driving birds.The use of AT89C2051 main microcontroller programming battery low voltage protection circuit,effectively protect the battery.Based on MSP430F1101 ultra-low-power microprocessor design to achieve device of driving birds power management circuit,by determining the entire ultrasonic device of driving birds work or not to reduce the ultrasonic device of driving birds static high power consumption problems.Finally,in the process of use,with a number of bird repellent can effectively solve the bird’s full-time protection problems.After long-term tests,it has been verified that the new type of photo-electricity-sensing ultrasonic bird-repellent bird feeder works reliably andstably,has a long operating time,and has a high success rate of bird repellent.
