Abstract: Through the overall analysis to the irrigation water management, according to the characteristics of data acquisition and monitoring, the author designed and completed a monitoring system which based on the wireless network GPRS. This system uses a SQL serve 2000 database and Delphi7 programming software, which includes several functions, such as the monitoring data acquisition, processing, voice communication and man-machine interface and so on. At the same time, this system adapted a kind of low power consumption and high performance embedded processors and GPRS module, carrying out the acquisition transmission control integration, solving the water supply engineering every link of the monitoring data acquisition and monitoring. It also provides some reliable solutions for the remote monitoring for irrigation water management.

Abstract: A design program of remote voice control system is presented based on the intelligent home on Android mobile phone platform.

This system is tested and proved its real-time, effectiveness and stability. Meanwhile, it can also provide a practical reference solution for human-computer interaction, having a wide range of application.

Abstract: A high precision, rapid and automatic high-voltage capacitor charging system is needed for pulse power system. A charging system based on high-voltage capacitor bank as energy storage device and c8051f020 MCU as control system, is designed in this paper .The hardware of this system includes a voltage measurement and control circuit, operation and display screen circuit, optical coupling circuit, fiber optical transceiver circuit. The software of this system uses closed-loop control algorithm to control the motor of voltage regulator, and the voltage of high voltage capacitor is charged from 0 to 20KV. By analyzing for the data of experimental and adopt the method of curve fitting, a modified voltage control algorithm is established. The modified algorithm improves the accuracy of charged voltage for high voltage capacitor to more than 99%.

Abstract: A novel integration method with stabilizing voltage and frequency, UPS, intelligent charging for mobile power supply has been proposed in this paper. Process of the advanced method can be divided into four steps, including the generating electricity, outputting stabilizing voltage and frequency, UPS, intelligent charging. The following works have been done in the study: the principle of the integration method, the topological structure of integration system, the Implementation of the integration method.

The system can be realized functions, such as the generating electricity, outputting stabilizing voltage and frequency, UPS, intelligent charging and so on. By the system, the high precision voltage amplitude and frequency is supply to outdoor load, and the UPS state is maintained.

Abstract: In smart transmitters with HART protocol, the HART physical layer implementation is critical for reliable communication. For the existing smart pressure transmitter circuit is complex and unstable, this paper designed a simple and reliable circuit in accordance with HART physical layer specifications. The design uses AD421 and AD5700-1 constitute a 4-to-20mA loop-powered smart transmitter circuit, is fully compatible with standard HART or other similar FSK protocols. The smart transmitter using this circuit has passed the HART certification by HART communication foundation. This implementation can be applied to other smart transmitters.

Abstract: According to the application of ABC classification in goods location layout, this paper deals with its expansion and optimization. By using the coordinate curve and matrix model, we comprehensively consider the storage capacity, the output frequency, the characteristics of the product and the other dimensions, thus building a model of scientific distribution of stock on the basis of products characteristics, finally formed an improved classification of multidimensional variable combination. This improved classification plays an active role in increasing the efficiency of capacity utilization, decreasing the storage time, improving the use of inventory facility, it is suitable for all kinds of warehouse.
