無線紅外貨車防盜系統(tǒng)


摘要

隨著現(xiàn)在油價高漲的愈演愈烈，以及現(xiàn)在運輸業(yè)的大力發(fā)展，使得貨車的油箱不再安全，由于貨車長途居多，一次需要儲存大量的油，再加上司機不可能時時在車旁，給一些不法的偷油分子可乘之機，偷走油，使得貨車司機苦不堪言。
   本研究旨在開發(fā)出一種利用紅外技術(shù)來防止車主不在車旁時對油箱的時時監(jiān)控，使得油耗子無機可乘，大大提高貨車油箱的安全性。其中運用到被動紅外技術(shù)以及無線傳輸技術(shù)。本設(shè)備分為兩部分，一部分為監(jiān)控端，安裝在油箱附近，用于時時監(jiān)控。另一部分為用戶端，佩戴在司機身上，時時接收貨車油箱的情況。本文重點在監(jiān)控端，用戶端由另一位搭檔完成。本設(shè)計為基本功能，其中再可添加功能，由于時間以及經(jīng)費的原因，只能完成基本功能。工作方法，當車戶離開貨車時，可開啟本系統(tǒng)，屆時監(jiān)控端的被動紅外開啟，監(jiān)視油箱周圍的紅外特征，若有人員靠近時間過長，將觸發(fā)無線發(fā)射端，發(fā)出經(jīng)過編譯的無線信號，客戶端接收之后經(jīng)過識別，得出油箱有異動，可作出防范動作。

ABSTRACT

With the intensified oil prices now, and now to develop the transport sector, making the truck's fuel tank is no longer safe, mostly because long-distance trucks, a need to store large amounts of oil, coupled with the drivers not always work out in the car and to some Touyou unlawful elements an opportunity to steal the oil, making the truck drivers miserable.
   This study aimed to develop a way to use infrared technology to prevent the owner is not near the vehicle when the tank from time to time monitor, so You Haozi no exploits, greatly improving the safety of the tank truck. Which applied to the passive infrared technology and wireless transmission technology. This equipment is divided into two parts, to monitor side, installed in the tank near to constant monitoring. Another part of the client, wearing the driver who always received the case of tank trucks. This article focuses on the monitoring side, the user Duanyou another partner to complete. The design of the basic features, then you can add features, as time and funding reasons, can only perform basic functions. Methods of work, when the car left the household goods, you can turn on the system, will monitor the end of the passive infrared open around the infrared feature to monitor the fuel tank, Ruoyou staff Kaojin too long, will trigger the wireless transmitter, a wireless signal sent through the compiler, After the client receives through the identification, obtained in an abnormal fuel tank can be made to prevent action.
