With the popularization of network cameras and the continuous development of image processing technology, visual⁃based fire monitoring systems have received more and more attention. The current method of visual⁃based fire monitoring system is to detect the flame generated after a fire. The disadvantage is that the fire has already occurred during the alarm. The proposed fire detection system firstly finds out the suspected smoke area through the motion detection and the motion characteristics when the smoke just appears, and on this basis, the smoke and flame detection are carried out in the suspected smoke area. The smoke detection combines the smoke color characteristics and texture features. Flame detection uses the combination of flame two color features to improve detection accuracy. The experimental results show that the system can provide an alarm before the fire spreads and accurately detect the location of the fire ignition point, so the effectiveness of the proposed method is verified.

The concept of variable parameter dialog box was proposed, focusing on the deficiencies of fixed parameter DCL dialog box in AutoCAD. The system automatically generated DCL files with the relative parameters according to the quantity of parameter that system actually required. And by the builtin VisualLISP in AutoCAD, the variable parameter dialog box was programmed. This defined and provided a new input method for AutoCAD user on the purpose of secondary development.

The composing parts based on geography position, and some typical Ad Hoc network router agreements based on the move of geography position were introduced. On the basis of one router agreement, one kind of new strategy of package transmission was put forward, and the problem of losing package when package is transmitted was solved. So it improves the agreement's stability, security and haleness.
