Abstract
Mechanical sextant is used for measuring vertical line from the starting dot pitch in hydrological measurement ship test at most of hydrological stations of Yellow River downstream. Incandescent lamps are the test symbol lamp in night flow test. But incandescent lamps have some shortage. In order to ensure the smooth and safety of night flow test, remote control type LED flash test symbol lamp is developed. LED light uses the solar battery for power-up. Special power line isn’t set up any more. Highlight LED displaces the general incandescent lamp. Using wireless remote control switch is the sign that light switch is completed by remote control. Turning off light automatically circuit during the day is set up to prolong the service life of the symbol lamp and save electric energy. Flashing lights circuit is set up to make the target more eye-catching. The section symbol lamp has been extensive application at all stations of the Yellow River in Shandong Province. It achieved better effect.关键词
