Description
Technical field
The present invention relates to a kind of IE of utilization browser, by the supervisory control system of Ethernet realization to long-range noise signal.
Background technology
Noise pollution is to one of bigger environmental pollution of people's influence, people's life, work is understood producing bigger negative influence than the noise of high-decibel, and is also unfavorable to the health of human body.It is the noise signal at scene to be gathered store and can not pass by the signal that effective transmission means will be gathered in real time that now general noise-measuring instrument adopted more, just do not reach real time monitoring function yet, so just limited the using value of noise-measuring instrument significantly yet noise.
Summary of the invention
The objective of the invention is at above-mentioned deficiency, provide a kind of by on feature board, embedding the noise real-time monitoring system that Web server is realized.On the monitoring client PC, only need utilize the IE browser to open corresponding web page monitored and just can realize real-time monitoring the noise acquired signal of long-range feature board.
Technical scheme of the present invention is:
The ARM9 microprocessor S3C2440 that adopts Samsung to produce based on the long-range noise monitoring system of Web is that core has been built a small-scale feature board platform, mainly comprise SDRAM, FLASH, Ethernet interface, power circuit and the peripheral noise signal acquisition system that designs by the I/O mouth, outside join by Ethernet interface and Ethernet, terminal by PC by the control that conducts interviews of IE browser.
The selected operating system of the present invention is Linux, itself does not provide network interface the ARM9 chip, by the pattern of extended network interface, provides the network interface of a DM9000E 100M, transplant by network interface card being carried out corresponding driving, realize the linkage function of feature board and external ethernet.On S3C2440, transplant (SuSE) Linux OS, add the driver of relevant hardware part, on processor, need to transplant a kind of Web server so that realize of the access to netwoks control of long-range PC to feature board, what this programme was selected is more common boa server, needs to write cgi script at last and realizes the dynamic web page access control function.The homepage address of noise signal monitoring is imported in the IE browser address bar at monitoring PC end, and trigger this application, browser sends to application on the Web server of feature board, Web server is given cgi script with the input of data use standard, call the capture program of noise signal by CGI the signal of gathering is delivered to Web server, Web server is handled the back with signal via cgi script and is generated html file, and the output of use standard at last HTML form is sent the noise signal destination file of noise signal collector collection back to browser display through Web server and given the user.
The invention has the beneficial effects as follows: can utilize Ethernet to realize the monitoring function of noise signal in real time, only need can realize real-time monitoring just landing long-range noise monitoring interface in the network address of input function corresponding plate Web server correspondence on the IE browser on the PC of monitoring client to the noise signal of long-range feature board collection.Carry out the loaded down with trivial details noise signal test and the access of data with regard to not entering the scene like this by special survey crew.
