[0002] At present, traditional lighting systems such as high-pressure sodium lamps or high-pressure mercury lamps are used in storage lighting facilities such as warehouses. Although the lighting effect is good, it needs to consume a lot of electricity every year. Traditional lighting systems such as high-pressure mercury lamps or high-pressure mercury lamps are increasingly unable to meet energy-saving requirements, and the life of high-pressure sodium lamps or high-pressure mercury lamps is short, and the maintenance workload is relatively large; if semiconductor road lighting systems are used, although they have energy-saving features, but Its cost is expensive, and its electrical circuit is not compatible with the high-pressure sodium lamp road lighting system currently used in large quantities. If the high-pressure sodium lamp road lighting system is to be changed into a semiconductor road lighting system, a large amount of infrastructure investment and a long construction period are required, and the transformation cost Too large, and will cause waste of original power equipment resources

Embodiment Construction
[0015] A lighting system based on AGV trolley following, including a central control module, a lighting control module, and an AGV control module;
[0016] The central control module is used to obtain the position of the AGV trolley and send an opening command to the lighting control module;
[0017] The AGV control unit includes a micro-control unit, a ranging unit, and a code-scanning positioning unit;
[0018] The micro control unit is used to obtain the distance information sent by the ranging unit and generate execution instructions;
[0019] The distance measuring unit is an ultrasonic positioning device, and the distance measuring unit measures the distance information between the AGV car and the follower and sends it to the micro control unit;
[0020] The code scanning and positioning unit includes a two-dimensional code laid on the indoor floor and a code reading device installed on the bottom of the AGV trolley. The code reading device reads the two-dimensional cod...

The invention discloses an illumination method based on AGV cart following; the method comprises the following steps: a range finding unit measures the distance information between an AGV cart and a followed user, and sends the information to a micro-control unit; the micro-control unit obtains the distance information sent by the range finding unit and forms an order, and controls the AGV cart todrive through an execution order; a code reader reads a two dimension code and sends same to a middle control module; the middle control module searches position coordinates associated to the two dimension code; an illumination control module searches an illumination unit associated to the position coordinates, and sends an open order to the illumination unit. The illumination system follows userbehaviors through infrared range finding of the AGV cart; in addition, the AGV cart identifies the ground two dimension code for positioning, and opens the illumination unit of the corresponding position according to the current position, thus effectively preventing the illumination unit from opening in a long time in a large scale warehouse; the method can adjust the illumination system according to user positions, is intelligent and convenient.
