Photoelectric data transmitting device

The utility model relates to a novel photoelectric data transmission device which is widely suitable for the information transmission between a stacker carrying out the online operation in the automatic warehousing system and a ground monitoring machine. The utility model is characterized in that the utility model is composed of a correlation type photoelectric switch (1) on a ground control machine (A), a programmable controller (2), a correlation type photoelectric switch on a moving machine (B), and a programmable controller. Two pairs of common correlation type photoelectric switches can replace an expensive infrared communication device, which can reduce the cost of the equipment. Because a special communication module is omitted in the device, the utility model has simple structure and the utility model can enhance the reliability. The utility model is also suitable for the information transmission between other straight-line running moving machines and other ground controlling machines.
