Embodiment
The utility model will be further described below in conjunction with accompanying drawing and embodiment.
A kind of grain depot grain feelings wireless sensor network supervisory system described in the utility model is seen Fig. 1, and this system comprises wireless sensor node 1, gateway node 2, GPRS network 3, Internet4 and Surveillance center's slave computer 5.One group of wireless sensor node 1 is responsible for gathering grain feelings parameters such as silo temperature inside, humidity, grain moisture content, insect pest, and the grain feelings parameter information of each monitoring point being gathered by the via node of its top layer is transferred to each the substation gateway in the networking articulation point 2.Gateway node 2 communicates with Internet4 by GPRS network 3 with Surveillance center's slave computer 5, and the keeper of grain depot monitoring center carries out Treatment Analysis by slave computer to the data of collecting, and makes and judging or decision-making.
Surveillance center is the maincenter of wireless environment supervisory system, is the key of the reliable efficient operation of total system.Fig. 2 is the structural representation of Surveillance center's slave computer in the utility model.The hardware platform of Surveillance center's slave computer is to realize by connecing the main flow computing machine Internet network and that windows2000 or windowsXP are installed.The software of Surveillance center adopts modular design, be under the .NET of Microsoft framework, to adopt VC.NET (Visual C++.NET) language to develop, and cooperate SQL Server database technology and Socket (socket) network programming technology to realize database manipulation and traffic operation respectively.The software design of Surveillance center should guarantee the integrality of systemic-function, taking into account system extensibility in the future again, and the software of simultaneity factor will have good reliability and compatibility.The software systems of Surveillance center mainly are made up of communicator module, database submodule and main interface module three parts.
Fig. 3 is a wireless sensor node block diagram in the utility model.Wireless sensor network node requires lower, the necessary low energy consumption of node hardware cost, the necessary Routing Protocol of supporting multi-hop in design among Fig. 3.The IEEE802.15.4/ZigBee agreement has taken into full account the wireless sensor network demands of applications, has equipment power saving, reliable communications, self-organization of network, characteristics such as self-healing ability is strong, with low cost, network capacity big, network security.By these basic demands, carried out supporting the hardware design of the wireless sensor network node of 802.15.4/ZigBee agreement.Among the design, the wireless communication chips of selecting for use is CC2430, and single-chip microcomputer is C8051.Temperature, humidity, grain moisture content, go mouldy, 5 grain condition monitoring sensors such as insect pest receive multichannel grain feelings parameter signal.Through simulation multiplexer 21, become one tunnel output, through signal conditioning circuit 22 feeble signal of sensing is amplified again, behind modulus (A/D) converter 23, become digital signal, handle through single-chip microcomputer 25, respectively the data of handling are sent into communication module (CC2430), the CC2430 inside modules is solidified the ZigBee agreement, and data monitored is launched.
Fig. 4 is a gateway node block diagram in the utility model.Among Fig. 4, the processing power of gateway node, storage capacity and communication capacity are more intense, and it is connected with sensor node network by CC2430 module 34 on the one hand, are connected with the Internet4 external network by GPRS communication module 36 on the other hand.Realize that two kinds of agreements directly change, the monitoring task of issue monitoring center sends to the monitoring center that links to each other with the Internet network to the data of collection.Gateway node mainly is made up of radio-frequency (RF) receiving and transmission module, central processing unit, storer, GPRS communication module four parts.
Gateway node mainly acts on: receive Monitoring Data from node, and to data proofread and correct, processing such as fusion, issue monitoring center then; Handle accordingly for the instruction that Surveillance center is sent out.Receive data division, or the CC2430 radio transmitting and receiving chip, can unify host-host protocol, guarantee the reliability of transmission; Owing to also will carry out data processing, aggregation node is additional sensor not just, to improve the ability that processor is handled data, adopts the C8051 series monolithic equally; Monitoring center is away from the monitoring point, and cost is higher in actual applications if adopt the industrial siding transmission mode, adopts existing GPRS network can realize the remote transmission of data, because it is charged by flow, operating cost is lower.Adopt the MC55GPRS module of Siemens Company to design the remote transmission that realizes data.The ICP/IP protocol that the MC55GPRS module is embedded greatly reduces the difficulty of design, has also improved the ability of other data of microprocessor processes simultaneously.It is connected with sensor network by CC2430 on the one hand, is connected with the Internet external network by the GPRS communication module on the other hand.
Low, the good reliability of the utility model cost can make based on the wireless senser gateway node of GPRS to obtain the Monitoring Data real-time Transmission, satisfies the requirement of low-power consumption simultaneously.Multiparameter grain feelings supervisory system of the present utility model is widely used in the various grain storage repository.
