摘要
为了解决有线车载应急逃生装置布线繁琐、抗干扰性能差的问题,提出了一种基于太阳能供电(充电)和超外差收发的无线车载应急逃生装置设计方案,采用太阳能充电技术和低功耗设计方法,解决了在无车载供电情况下的供电问题,采用Keeloq滚动码技术解决了系统的抗干扰问题。理论计算及工程实现表明,该设计具有高可靠性、低功耗等特点。在平均日照达2 h的情况下,设备无需外接电源即可保持长时间处于工作状态。
In order to solve the problems of complicated wiring and poor anti-jamming performance of the wire vehicular emergency escape device,a design method of wireless vehicle emergency escape device based on solar power(charge)and superheterodyne receiving is presented.The problem of power supply without vehicle power supply is solved by using solar charging technology and low power consumption design method.The anti-jamming problem of the system is solved by using Keeloq rolling code technology.Through the theoretical calculation and engineering implementation,it is proved that this design method has the characteristics of high reliability and low power consumption.When the average sunshine reaches 2 h,the equipment can be kept in working state for a long time without external power supply.
