Warehouse Logistics Control and Management System Based on RFID

This paper introduces the hardware and software of the warehouse logistics control and management system based on RFID (Radio Frequency Identification), and explains the design scheme and implementation method of the system. The read/write operation is done using the electronic tag through a tag reader. The logistics control is implemented with PLC by communicating with SIEMENS WinCC configuration software and OPC technology. By accessing a SQL Server, functions such as automatic data storing, querying and deleting of goods and warehouse information are realized. Combining the former technique, the operations such as warehousing, warehouse delivery and goods moving are accomplished. This paper provides an application example of the integration of electronic tag technology and logistics control/management.

Design of wireless temperature and humidity data collection system based on MSP430 and CC2530

Through a combination of ZigBee technology and infrared remote control technology, air-condition controller can be built to realize functions like remote monitoring, remote control, and will be more intelligent. On the basis of ZigBee protocols development, the system uses low-power chip MSP430 and CC2530 RF chip, to control the air-condition, monitor and adjust the indoor temperature and humidity, and other functions. This paper introduces compiling of the protocols between the MSP430 and CC2530, and the process of data collection and uploading. Experimental tests show that the system can operate stably and reliably. There is no doubt that it will have a good application prospect.

Research on the low-power of air-conditioner remote control system terminal device based on Zigbee technology

In the field of intelligent home, when using Zigbee technology to network the management of air-conditioner control device, it is very necessary to reduce the power consumption of battery-powered devices in the network. Through the research of Battery-powered equipment composed by the CC2530 and MSP430, we provide a practical way to extend the working hours of the equipment, to reduce the power consumption and to save the overall cost of the system from both software and hardware devices optimized. Test results show that, after low-power processing the terminal equipment, the working time of the two batteries, whose capacity are 800mAh 1.5V, grow from 11 days to about 280 days.

The PV array maximum power point tracking in the shadow of conditions

The output of photovoltaic array has several corresponding local peaks of power-voltage curve with the existence of the shadow, In order to make the photovoltaic arrays continue to work in the maximum power point, need to create conditions for the model of the PV array, On the basis of the model, there are having some further detailed analysis and research about the characters of the local photovoltaic array under the shadow. A method was proposed which the maximum power point tracking of photovoltaic array, In order to achieve a novel method based on disturbance observed maximum power point tracking. This method is executed by DC-DC circuit which is controlled by the algorithm TMS320F28027 processor. To achieve maximum power photovoltaic (GMPP) output under complex conditions.
