Based On Zigbee Technology Logging Data Acquisition System Design

Nowadays,because of the continual exploration and destruction, the oil resources have decreasing gradually, and facing the point of exhaustion.Facing the current situation, how to improve the exploration efficiency,reduce mining the costs and the accidents, which has draw the attention of the related departments gradually.Oil equipments play an important part in the process of oil exploration. Sophisticated instruments can help the construction workers with mastering the project status accurately,increasing efficiency and reducing accidents. Comprehensive logging instrument as an important means of oil exploration and development has been more attention. Comprehensive logging instrument typically used a centralized data collection or field-bus-type wiring, as well complex market environment, coupled with wiring work was large and cumbersome, thus achieving the wireless acquisition systems should be a development direction.Basing on the research of wireless sensor network technology,this text have proposed the idea of comprehensive logging of wireless data acquisition system.It can solve the question of the wiring in the Construction site. Wireless sensor network technology is relatively low cost and wireless,In many areas it has been adopted and have a good effect, such as industrial control, data acquisition, hydrological and meteorological monitoring, small and medium sized wireless networks.On the basis of analysis and research on development situation of wireless sensor networks technology at home and abroad to study, short distanee communication technologies and IEEE802.15.4/Zigbee Protocol, the architecture of wireless sensor network system and the design scheme of data collection nodes are proposed in this thesis. The article realizes intelligent identification by using of electronic datasheet which refers to IEEE 1451.So that the node has a network recognition. According to the data collection in the oil field, the article mainly focuses on the analysis of the analog signal,the pulse volume and the winch capacity, designes corresponding to the three types of nodes and the communication gateway.As the core of CC2430 RF chip,it establishes a working frequency of 2.4GHz in full compliance with ZigBee protocol platform for wireless data transmission, In the environment of IAR development,it compiles procedures of the collection node to achieve the acquisition of wireless sensor network data transmission between nodes. This design has some practical value and prospects of the wireless future logging projects the foundation has played a certain role.
