Abstract
The utility model provides an intelligent voice warning board comprising a warning board with a warning slogan written on. The voice warning board is characterized in that the warning board is provided with a microwave sensor H, a switching circuit, a voice alarm module and a light emitting alarm module, wherein the output end of the microwave sensor H is connected with the voice alarm module and the light emitting alarm module through the switching circuit. When people approach, the microwave sensor detects that people moves within the range of detection and then outputs high level to close the switching circuit, consequently the voice alarm module is triggered to give out alarm sound and simultaneously, the light emitting alarm module works and emits light for alarm, and audible and visual alarm is to be stopped in 10 seconds. On the basis of the existing slogan warning, the voice warning board is added with the audible and visual alarm, thus being complete in functions and ideal in warning effect and reducing neglected situations, especially in night or under bad light.
