The invention provides an infrared data communication device and method applied to a sorting system and the sorting system. The communication device comprises a communication control module, a signal processing module for processing a data signal, an infrared receiving tube for receiving infrared data from an external device, and an infrared transmitting tube for transmitting the infrared data to the external device, wherein the signal processing module is used for converting the received infrared data into a digital signal and transmitting the digital signal to the communication control module; the communication control module is used for encoding the digital signal by adopting a differential Manchester encoding method; the infrared receiving tube is used for transmitting transmitted data provided by the communication control module to the external device in a form of the infrared data; and the communication control module is an FPGA processor. The problem of different high and low level duration caused by a change of the receiving light intensity in infrared data receiving and transmitting in the motion process is solved; and the transmitted data are encoded and decoded by adopting the FPGA processor according to differential Manchester encoding, so that the amount of transmitted information within unit time is improved.
Description
technical field [0001] The invention belongs to the technical field of cargo sorting, and in particular relates to an infrared data communication device, method and sorting system applied to a sorting system. Background technique [0002] The cross-belt sorting system is connected by the main drive belt conveyor and the trolley (referred to as "cart") carrying a small belt conveyor. When the "cart" moves to the specified sorting position, it rotates The belt completes the task of sorting and sending out the goods. The main drive belt conveyor carries the "car" to move around the circular track repeatedly. When the car passes through other components of the system, it needs information interaction to complete the corresponding task. Due to the limitation of many technical factors, most of them use infrared communication to realize the information communication between the "car" and other units. [0003] Existing infrared communication modules used in cross-belt sorting syst...
