With the application scale and area of the building PV power station continuous extension, data transmission and monitoring management of the building PV power station have become increasingly important.This paper introduces a kind of data delivering and distributed monitoring management system of the building PV power station based on ZigBee wireless network,this system has information transmission modules based on ZigBee wireless network, region monitoring and magement module and remote access module. ZigBee wireless network could deliver datas of the building PV power station to the center of region monitoring and management system,ultimately,the datas were deposited in the database of region monitoring and management system,The Electricity Regulatory Office and The Power Company used remote transmission and monitoring system by remote access system on the Internet, to access data reports of the building PV power station in the database of region monitoring and magement system.System test results can carry out the building PV power station’s data transmission, monitoring system’s data management and remote access by the Internet.

Acquisition Task

The 3G wireless network video acquisition system based on the DM6446 is designed, which ARM side of DM6446 complete the main control functions of the system, then it calls H.264 video compression algorithm in DSP side of DM6446 through the Codec Engine, which greatly improves the efficiency of the system, and the RTP protocol control data transmission in the CDMA2000 network. The monitoring display terminal gets video resource by accessing the corresponding IP address. The experimental results show that the system designed completes wireless network video acquisition task safety and reliably, and the image is clear, also the video is coherent.

The Smart power meter system based on ZigBee technology is successfully developed in the paper. The EM250 SOC chips are adopted to develop the wireless communication modules with ZigBee protocol. Parsing the AT command, encryption and such more basic function, the two different and independent program framework for the ESP and IHD(In-Home Display) have been worked out except finishing the data transmission. A smart wireless network based on ZigBee has been established. The home and outdoor testing have also been implemented too. The measured results show that a coordinator can support more than 500 nodes and communication distance reach more than 1000 meter outdoor and more than 50 meter from home to outdoor through the two walls.

Ground Penetrating

A wireless data transmission system used to realize data transmission of ground penetrating radar (GPR) is designed. It including data receiver and sender overcomes the disadvantages of traditional GPR cable transmission system. STM32F407 chip and ATK-RM04 are core components of data sender. PC with a wireless network card is data receiver. System is designed with reference to C/S network model. Data receiver and sender are respectively developed with VC++ socket and RAW API of Lwip TCP/IP protocol stack. CP protocol is chosen as network transport protocol. Practical applications show that system can stably transmit data within 0m-20m and maximum loss rate is 0.005%. It is reliable and convenient for GPR’s application.
