Emergency Control System Of Low Altitude Remote Sensing Airship

With the development of low attitude remote sensing, study of the low attitude remote sensing platform improved rapidely in recent years. Because there are some advantages such as low cost, little risk, simple handling and convenience maintenance. Little remote controlled airship, as a kind of platform, becomes more and more popular today. With the research in recent years, there are series of great improvements in stability and security. However, as a kind of low speed, air floated and low atitude aerocraft, remote controlled airship is not reliable enough, comparative with plane. The air lines can be changed by winds easily. And, there are some dangerous status, such as downfallen and floating in atmosphere, when airship in trouble. Nowadays, there are some problems in the security institution of little remote control airship. Therefore, researching of emergency control system is a practical means to protect instruments.In the research, I try to improve the old remote control system, which has been produced by our department. Computer in airship is used to monitoring the status of the airship with series of sensors. Then, computer in land base receives the digital information through wireless communication, and displays them in visualization. Based on integration of two computer systerms, the emergency control system of low altitude remote sensing platform (ECS) has been worked out. When dangerous occured, ECS system starts emergency control module automatically, to regulate or control airship landing securely and insure the safety of the aircraft and its remote sensing instruments.This paper introduces the frame design and all kinds of function of the ECS system, in order of system designing. There are some key points that have been explained in detail. And the method of programming development in Visual Basic environment has also been introduced.The ECS system realizes the monitoring of low atitude remote sensing platform. And the reference informations have been shown in visual form, which improve the efficiency of remote control. The system avoids all kinds of accidents effectively. It not only enhances the stability and security, but also protects airship and its instruments. There will be a bright future in using it.
