Based On The Rs485 Bus And 433m Gfsk Wireless Data Communications Logistics Warehouse Picking Systems Engineering Design

With the quickly development of economic and technology, Many technology include Computer, Communication, Network have been applied deeply to each part of logistc management. Storehouse Picking System is a important part of logistic information technology. Via the picking system, when it's need to execute a import/export operation in a storehouse, operation information can be sent to the right goods position in firstly time. It make the picking worker can arrive the right process position in the storehouse rapidly. And the operation result can also rapidly feedback to the computer of the management system. The picking system quite change the originality and behindhand situation of manual picking operation. In the same time, the efficiency of picking operation is raised, and the management cost is reduced.This dissertation introduce a engineering designing work of a logistic storehouse picking system based on RS485 bus and 433M GFSK RF data communication. The electronic label which is installed in each goods-position is connected to the RS485 bus, and a goods-zone controller manage and control every electronic label of the zone. The goods-zone controller communicate with the center computer via GFSK data communication in 433M ISM band. In this way, a integrity communication system is established. The main content of this dissertation include: the whole project of system, the description of each important device, the introduction of hardware designing, the introduction of controlled software designing, and how the original information be sent to the terminal through different media and how the feedback information return. During this dissertation, there are some detail introduction of important component which are applied in the system: NRF905 single chip radio transceiver, IDT7005 dual port SRAM ,etc.The design of the system communication mode and the implement way of each function equipment of the system which are introduced in the dissertation ,have a high value of popularization in the field of logistic information technology.
