AGV light navigating/positioning system

The invention discloses an AGV light navigating/positioning system in the technical field of positioning and navigating. The AGV light navigating/positioning system comprises a controller, an obstacle sensor, a magnetic navigating sensor, a landmark sensor, a light sensor, a driver and a storage battery. The obstacle sensor, the magnetic navigating sensor, the landmark sensor, the light sensor and the driver are connected with the controller. The storage battery is connected with the driver and the controller. According to the AGV light navigating/positioning system, information needing to be transmitted in compiled into a section of modulating signals and is added to the driving current of an LED lamp in a pulse width modulation mode, a light source is used as a transmitting carrier, when a user enters a lamp lighting area, a mobile phone can analyze the unique identity recognition information sent by the lamp, the unique identity recognition information is matched with the position information of a map database so that positioning can be completed, the positioning precision is within one meter, and the positioning time is short.
