Description
Technical field
The invention belongs to the technical field of physical department, relate to the electromagnetic radiation measuring technology, particularly a kind of electromagnetic radiation measuring and analysis system.
Background technology
The quickening of building well-off society's paces along with China will obtain faster development as the basic industry power industry of national economy.According to the long-range developmental program of State Grid's industry, the Eleventh Five-Year Plan period China's power consumption will will double on the basis of existing power consumption by 2010 with 10% speed increase every year.To form with 500 kilovolts be that trunk rack, 220 kilovoltage grades are the powerful electrical network of urban distribution network to nationwide integrated power grid when the time comes.Consequent power frequency electromagnetic field will more and more be subjected to people's attention to peripheral ecologic environment, installations and facilities and vast electric power worker with the problem that influences of closing on residents ' health.This shows that the frequency electromagnetic radiation of project of transmitting and converting electricity project has become the problem that can't avoid at present, handle the bad image that not only can damage Utilities Electric Co., sometimes even can have influence on the normal operation of system, cause enormous economic loss.Given this, carry out the subject study of frequency electromagnetic radiation aspect, strengthen the test and the monitoring work of existing power engineering project power frequency electromagnetic field present situation in operational process.Especially the latter seems very important, and carrying out of this work needs a large amount of accurate, flexible to operation, low-cost measurement and analysis instruments of measuring.The present domestic import equipment that generally adopts, beyond any doubt, external instrument and equipment not only costs an arm and a leg but also operates neither be very convenient flexible.
Along with people were to the attention of frequency electromagnetic radiation measurement and guard technology in recent years, Techniques in Electromagnetic Measurement has also obtained development faster.Domestic electromagnetic compatibility equipment great majority commonly used at present are external imports, common electromagnetic compatibility equipment has the EMSCAN analyser of the electromagnetic scanning that is used for the PCB version of Canadian EMSCAN Corp. (CA), the EMI of the CASSPER EMI System of CASSPER company and U.S. DSII company, TEMPEST electromagnetic analyzer etc.These products mostly have preferable performance for high frequency radiation, though some has the Measurement and analysis function of low frequency, but still there is the deficiency on the function, and the equipment volume and the weight of the electromagnetic measurement analyser of above-mentioned several companies are relatively big, secondly mobile underaction is the price comparison costliness.Though high frequency and low frequency electromagnetic analyser weight that Italy PMM company produces are little, easy to carry, cost an arm and a leg, still not very convenient in the use.
Though up to the present the domestic research that has some research units to carry out the frequency electromagnetic radiation surveying instrument also do not developed stable performance, measured device accurately.Though carried out the development of power frequency magnetic field probe jointly as labour protection research institute of State Power Corporation and Wuhan High Voltage Research Institute, installed relatively large and can't obtain gratifying result to electric field probe.Though Beijing Kehuan Century Electromagnetic Compatibility Technology Limited Liabilit has ripe product to sell at home, its product is mainly the radio interference testing apparatus, and is also powerless to the power frequency part.And do not see as yet that based on the comprehensive field strength measurement system that utilizes wireless mode transmission measurement signal and carry out analyzing and processing of the present invention research report is arranged.
Though the comprehensive field strength meter of PMM8053 has very big advantage than miscellaneous equipment at the aspects such as accuracy of operation and performance, still there is following weak point in it:
(1) adopt optical fiber to be connected between main frame and the probe, main frame must move simultaneously with probe during measurement, operates dumb; Be subjected to the restriction of fiber lengths, the data of some particular point (on shaft tower) can't be measured.In addition, when in high voltage environment, measuring, also there is potential safety hazard.
Electric field when (2) main frame can only be stored in-site measurement or magnetic field strength date can not be stored other and be measured relevant parameter (as measuring the information such as position of place, date, measurement point), more can not in time provide test report.
(3) measuring system can not be carried out detail analysis processing operation to data.As, carry out aftertreatments such as spectrum analysis, graphical data etc.
(4) system can't realize the real-time continuous monitoring.
(5) cost an arm and a leg.At present, purchase the 8053 frequency electromagnetic radiation measuring systems that the Italian PMM of cover company produces, need about about 200,000 yuan of Renminbi.Such price all is difficult to accept to most of domestic enterprises.
Summary of the invention
The object of the present invention is to provide a kind of electromagnetic radiation measuring and analysis system, this analysis system cost is low, weight is little, easy to carry, and operation of equipment is convenient, flexible.Can be to the test and the monitoring of power engineering project power frequency electromagnetic field present situation in operational process.
The object of the present invention is achieved like this:
The present invention is made of hardware and software system two parts: hardware system comprises the electromagnetic radiation measuring analytical equipment that is made of measuring sonde, two communicator and computing machine; Software systems comprise Measurement and analysis software and Data Post software two parts, Measurement and analysis software is mainly used in the data-signal that collection is transmitted by probe, the processing such as line item, storage and spectrum analysis of going forward side by side, in addition can be to probe transmit operation order, Data Post software mainly is to finish the drafting that whole field domain internal electric field distributes according to measurement data, comprises the drafting of field pattern and pattern of equipotentials etc.
In two communicator of electromagnetic radiation measuring analytical equipment one links to each other with measuring sonde (containing light/electric signal and baud rate modular converter in this communicator) by short fiber, and another in two communicator is connected with computing machine by the USB serial ports; Described measuring sonde sensed data signal becomes light signal through modular converter, by optical fiber optical signal transmission to is measured communicator again, this measurement communicator changes light signal into electric signal again and is sent to connection another measurement communicator on computers through transmitter module, and this communicator is carried out comprehensive analysis processing such as data read, storage with data again from USB serial ports input computing machine and by the testing software analytic system; System is after receiving the ready order of probe, read the signal that electric field still is a magnetic field data by sending to probe with opposite just now transmission channel, determine the back data of transmission directions X earlier, send the signal that reads the Y directional data after receiving successfully again, send the data that the Z direction is read in order after the success again, three component datas calculate comprehensive field intensity after reading respectively and finishing again.
The invention enables this measuring system taking advantage aspect price and the operation of equipment dirigibility, have vast market prospect.In case this project achievement is introduced to the market, will create huge economic benefit for enterprise.
