Design Of High Voltage Protection And Lightning Protection Alarm For Communication Engineering Vehicle

With the development of information technology,there are more and more applications of mobile communication network in the information battlefield.In this application,the communication engineering vehicle of the mobile command communication system has the characteristics of fast,flexible and independent establishment of site and local area network,and can adapt to various geographical,climatic and different seasonal environment.Therefore,the development of the communication system is widely paid attention to.As a frontier communications personnel,the formation of the mobile command center and the distribution of the communication engineering vehicle make it more necessary for us to maintain the communication vehicle.At the same time,to effectively prevent the communication engineering vehicles from touching the high voltage line and the external shock caused by the damage to the equipment and the casualties,the high voltage shock and the electric shock are eliminated in time.The hidden danger of lightning protection is combined with the actual cases of electric shock and lightning strike in recent years.The design idea of constructing the anti touch high voltage electricity and lightning protection alarm is put forward.After the analysis of the feasibility and reliability,the whole design idea is established,and the importance and development direction of the modern communication engineering are described.Finally,the application of communication engineering vehicle in modern army is briefly introduced.The high voltage detection circuit composed of three axis digital compass IC Honeywell HMC5883 L sensor and single chip microcomputer STC89C52 is used technically.The MCU reads the data of the HMC5883 L sensor through I2 C,and according to whether the result of the detected data reaches the threshold value for different modes of alarm,the reliability is high and the false alarm rate is very low.In addition,the design has both the ultrasonic distance measurement module and the temperature display module,which can display the data in real time on the LCD electronic display screen,for the operator to refer to,can effectively avoid the electric shock accident of the engineering vehicle,and can achieve a certain obstacle avoidance effect.It has very important practical significance.
