A LBS-1 fire accuracy measurement system was set up.Influence factors including detection circuit of photo-electricity transforming and accepting,and brightness of sky background,were analyzed.Some measures were put forword to improve the detecting sensitivity,such as choosing the photo-electricity tube with linked rectangle,high frequency response,low noise as detection parts and applying adjustable diaphragm,multi-adjustable comparison voltage.So shy-screen can work well over 500 lx.It is proved that the improving measures work reliable with better stabilization,and can improve the performance of photo-electricity detection of sky-screen.
