被动式汽车防盗系统的研制

A Study of the Development of Passive System of Auto Theft Prevention

为适应大量中低档汽车逐步进入家庭、实现汽车防盗的需要 ,在对各类典型盗车实例进行调查的基础上 ,对流行的各类常规防盗装置的不足进行了分析 ,研究并试制成功了一种被动式防盗系统 .对汽车油路、温度、油压、启动电路、点火电路分别设置防盗故障点的试验和分析后证明 ,将故障点设置在点火初级电路 ,利用自行设计的、独特的惯性速度开关 ,系统能在汽车行驶速度为 0～ 3km/h时起作用 ,可靠地实现防盗功能 .其最大特点是改变了常规、传统的防盗模式 ,即使专业人员也难以发现和破译 ,从而增强了防盗的可靠性 .

To meet the need of auto theft prevention with mamy economy cars coming into ordinary families,the author succeeded in developing a passive system of auto theft prevention after investigating and analysing various auto theft cases.This system is made of simple mechanical and electronical components accordingto its characteristics.In practical tests,this system can start work at the speed of over 0～3 km/h and therefore guard against thefts effcetively.The greatest characteristic of this system is it has changed the general and traditional open devices into secret and passive device of guarding against thefts.
