TinyOs Wireless Sensor Networks Based On Universal Monitoring System Design And Implementation

Universal monitoring system for wireless sensor network monitoring system increasing role. System design common environmental monitoring systems, agricultural monitoring systems, smart home monitoring systems are specialized areas in order to solve problems in various fields for the monitoring system design, propose a universal monitoring system design. As wireless sensor networks, microprocessors and embedded operating systems evolving, TinyOS wireless sensor network monitoring system gradually occupied universal dominance.This paper studies the realization of universal monitoring system for wireless sensor networks in the role of TinyOS operating system versatility, analytical design method development at home and abroad as well as the monitoring system used to monitor the system. The main factor affecting the basis of another universal monitoring system design carried on, there is the traditional method of monitoring system design configurability, scalability and impact of operating system features for versatility and monitoring range is relatively narrow range of issues presents a fully realized the environmental, industrial, smart home monitoring systems based on TinyOS wireless sensor network monitoring system common approach and completed on the basis of this design method based on general-purpose monitoring system using the PC side of the collection The data is parsed and stored, in order to achieve the latter part of the data analysis, and make the appropriate data processing.Herein as a generic monitoring system CC2530 RF communication module and a microcontroller(MCU), completed the design of wireless sensor network communication system, is to achieve commonality of hardware and software system versatility. The hardware is available to users versatility and rich modular sensor interface, so that the system can solve the configurability and scalability issues without the need to change the hardware design of the case. The versatility of the software from the PC side of the gateway system design, three sensor component interface and data communication protocol NTLV TinyOS system(NID-TYPE-LEN-VALUE)three aspects to solve common problems, and common communication protocol based NTLV Common data protocol system design, NTLV format specific sensor node number, design sensor type, sensor data and sensor data length, universal wireless sensor network communication protocol for the monitoring system is capable of data exchange between different platforms provide a greatly The convenient.Achieve universal monitoring system hardware design and software design TinyOS wireless sensor network monitoring system common, testing and use of field projects reflects the system is stable, and general monitoring system to achieve the performance and stability of wireless sensor networks and monitoring data accuracy value error is less than 2.46%.
