The Design And Implementation Of Distributed Trace Hydrogen Analysis System

Using the hydrogen concentration changes to predict earthquake has become ahotspot at home and abroad, there are many defects in the instruments used to measure theconcentration of hydrogen, such as low sensitivity, complicated operation, continuousmeasurement and high prices.Aiming at this problem, this paper designs and implements a distributed TraceHydrogen Analysis System. Combined with the chemical micro-sensors, the systemrealizes real-time monitoring and unified management of changes in hydrogenconcentration around. The system also provides users with a variety of interactive visualdata analysis methods.This paper studies a method of control and measurement of distributedtrace hydrogen, designs the communication protocol between the measuring terminal andthe chemical micro-sensors, achieve to control the chemical micro-sensors to measure inthree different modes. In order to provide users with high-quality and high-reliabilityremote access and control, the paper designs and implements various network terminalserver through the study and comparison of different server programming paradigms andFlash mechanisms for network communication. Then the paper proposed an effectivestrategy for transmission and simultaneous backup of distributed data. Aiming atproviding data reliability protection for the distributed system, the strategy usestime-triggered and event-triggered to ensure real-time data synchronization between thecentral data server and each measuring terminals. At last, expect to provide valuableinformation for earthquake prediction, the paper designs three methods of data analysisand visual display based on data collected by distributed terminals.This system can effectively measure for a long time, it is sensitive, easy to operateand has provided some valuable data and information for earthquake prediction, which hasbeen proved by the test and practice.
