Introduction
Modern social intelligent management system has entered all walks of life, the innovation of this product is for warehouse intelligent management, it can make management convenience and intelligence, saving manpower and material resources, and can make full use of warehouse high altitude space, saving cargo area; especially for the management of precious goods, we set the authority card activation device operation, and can operate the record to encrypted TCP / IP protocol through the network to send the computer’s host computer system by network, the computer can real-time detection The use of records; for small and medium enterprises and courier companies and other warehouse management, can reduce costs, improve efficiency, safety performance is also very reliable.
Theoretical Analysis and System Composition Program Demonstration. Controller Module. MSP430 series of single-chip, which is the 16-bit single-chip produced by TI company, the main feature is ultra-low power consumption, with a reduced instruction set of mixed-signal processor, instructions are single-cycle instructions, strong, fast running, The internal hardware multiplier and a large number of registers provide a guarantee for storing data and operations. Its ultra-low power consumption characteristics for instrumentation and other design, here use 430 series single-chip as our switching power supply control module in line with our design requirements. Network Module.YIXIN_W5500 Ethernet module is a Ethernet module based on the WIZnet W5500 chip , is a good performance, cost-effective Ethernet module. Module integrated hardware TCP / IP protocol; internal 32K bytes of memory as a TX / RX cache; support 10 / 100Mbps network transmission rate; support 8 independent ports running at the same time the module also supports 3.3V or 5V power supply,5V power supply can also output 3.3V voltage, user-friendly in a different microcontroller system to use; module and single-chip system communication is simple and convenient SPI bus communication. The specific work process is: the Ethernet module set up a virtual server, in its communication program to write the computer’s IP address and port number, and then use the host computer system, create a client on the computer, after the server starts successfully, wait for the remote server to connect [1]. When the network is connected smoothly, the port 0 of the W5500 will automatically establish a connection with the server to transmit and receive the data.
Near Field Communication Card Reader Module. R radio frequency identification technology is an automatic identification technology which has rapid development and very wide application prospects. The entire system includes readers, tags and antennas [2]. The reader mainly completes the reading and writing of the electronic tag data and uploads the data as needed. The choice of credit card module because the campus student’s campus card is IC card. So we need to choose to read the IC card information card chip and circuit. Here we choose MF RC522 as our card number reading module. The MFRC522 internal transmitter section is capable of driving a reader / writer antenna design with ISO / IEC 14443 / contactless card reader cards and transponders without additional active circuitry. The receiver part of the ISO / IEC 14443 / contactless card reader compatible card and transponder provides a demodulation and decoding circuitry that have a powerful and efficient implementation signal receive the data.

Software Design Choice. There are two options for master control chip selection. Scheme 1: MSP430 series of single-chip, which is the 16-bit single-chip produced by TI company, the main feature is ultra-low power consumption, with a reduced instruction set of mixed-signal processor, instructions are single-cycle, strong function and fast running. Scheme 2: 51 series of single-chip. The series of microcontroller have 8-bit , using a complex instruction set, the application is widely wide, for the speed requirements are not very high system can be applied, and low prices. As a smart warehouse management system design, we need to take into account the power consumption and processing speed of the problem, where the intelligent warehouse management system through the network and the host computer for information exchange. This requires the main controller to have high-speed running capacity and strong information processing capabilities. The MSP430 family of microcontrollers is known for its ultra low power consumption and is therefore suitable for use as our main controller. So here we choose MSP430F5529 microcontroller as the main controller of the software part. Software Design Part of The Flow Chart. The following is the system software design flow chart, specifically describes the system card operation and mechanical device action.
Summary
Intelligent warehouse management system is mainly used in courier companies and some small and medium-sized enterprise warehouse management, to achieve warehouse management automation, intelligent, small and economical. Intelligent warehouse management system applications to ensure that all aspects of cargo warehouse management data input speed and accuracy to ensure that enterprises timely and accurate grasp of the real inventory data, reasonable to maintain and control business inventories. Through the scientific code, can easily manage the inventory of goods batches, shelf life. The use of the system’s location management functions, but also can grasp the current
location of all inventory of goods, is conducive to improving the efficiency of warehouse management.
