Description

A kind of intelligent radio open loop magnetic flux harvester
Technical field
The utility model relates to a kind of intelligent radio open loop magnetic flux harvester, belongs to magnetic flux detecting sensor technical field.
Background technology
British scientist joule in 1842, find magnetoelastic effect, when the external mechanical load that ferrimagnet bears changes, the magnetization (magnetic permeability) of its inside changes, by measuring the magnetic permeability change of the component that ferrimagnet is made, measure the internal force of component.
Along with magnetic flux transducer development, continuing to bring out the open loop magnetic flux product made new advances. open loop magnetic flux adopts the structure of open loop, can easily be arranged on built cable, and can take off from cable, test other cables, mobile test can be carried out, use comparatively flexible, open loop magnetic flux transducer, there is the structure of open loop, during convenient test several cables, also creating some problems has to be solved, during the multiple cable of mobile test, the numbering of cable can not be distinguished, the data obfuscation of several cables may be shone into, the cable of test different-diameter, need to change corresponding magnetic flux transducer, the size of magnetic flux transducer is less, driving voltage is lower, when the overtension of Acquisition Instrument to sensor, sensor may be damaged, known open loop magnetic flux acquisition system not charged pools, a wire need be dragged later to power when traverse measurement, test is got up more inconvenient, the data that known open loop magnetic flux acquisition system obtains, after need being completed, upload in remote terminal server by computer, more loaded down with trivial details, can not when gathering, timely uploading data processes to computer center.
Summary of the invention
In order to overcome above-mentioned defect, the utility model object is to provide a kind of intelligent radio open loop magnetic flux harvester.
In order to achieve the above object, the utility model adopts following technical scheme:
A kind of intelligent radio open loop magnetic flux harvester, it comprises one and is attached to RF-ID on cable to be measured, is enclosed with magnetic flux transducer, magnetic flux transducer is provided with card reading module at the outside surface of cable to be measured;
Acquisition Instrument is connected with the single-chip microcomputer in magnetic flux transducer by cable;
Battery and built-in DTU is included in described Acquisition Instrument;
Acquisition Instrument is connected with host computer by serial bus.
Described host computer is computing machine.
Described RF-ID is the numbered RF-ID of band.
Described built-in DTU is connected with Remote Computer Center.
Cable to be measured is connected with single-chip microcomputer by inner I2C bus.
Principle of work:
First it place RF-ID mark on cable to be tested, magnetic flux transducer is when detecting cable magnetic flux, read No. ID of cable by the RF-ID card reader on sensor simultaneously, while the information of return data cable magnetic flux, No. ID of Return flux cable, like this in the data of test cable also with cable number information, thus avoid mobile test the test data of each cable obscured.
For the voltage error preventing acquisition instrument to be supplied to sensor, the built-in singlechip chip of sensor, the driving voltage of storage sensor, the information such as production code member, acquisition instrument connects sensor, is obtained by bus, the information of sensor, sensor is according to these information, and the output voltage of adjustment Acquisition Instrument automatically, avoids the sensor changing obstructed model should be the driving voltage difference of sensor and burn out sensor.
Acquisition instrument internal battery, charges to battery by power supply, after battery charging, by powered battery, breaks away from the electric wire constraint of limited power, tests the cable of diverse location.
The data obtained are given computer center at operation acquisition instrument by DTU and are preserved by Acquisition Instrument built-in DTU module in time, and can by computer center in real time to the data analysis obtained.
The beneficial effects of the utility model:
1. the utility model achieves the automatic identification of open-loop magnetic flux sensor to cable, and the test data avoiding different cable is obscured, and ensure that the correspondence of test data and measured cable, prevents the not corresponding cable of test data, and causes test result mistake.
2. the utility model achieves the automatic identification of Acquisition Instrument to different sensors. and after reading the information in Open-loop sensors, the excitation power supply automatically exported, after changing the little sensor of driving voltage, it is too high and damage that sensor should be acquisition instrument output voltage.
3. the utility model is equipped with battery on acquisition instrument, and test diverse location cable, does not need to carry out bracing wire, can test easily.
4. the cable magnetic flux tested of the utility model, issues computer disposal center by DTU simultaneously, facilitates preservation and the analysis of data.
