Description
Technical field
The present invention relates to wireless senser field, particularly relate to the wireless senser of special applications.
Background technology
The application of wireless senser in security monitoring, automatic management etc. is more and more extensive.But some particular component is due to the singularity of itself, very high requirement is proposed to the shape of sensor, volume and working method.Such as, owing to often wanting switching action, there is loose contact, contact be oxidized the too high phenomenon of temperature caused, be necessary that mounting temperature sensor is monitored in the dynamic and static contact of power switch cabinet.If the rotating shaft of train or lathe, transmission shaft because friction cause temperature too high, greatly can reduce serviceable life, even cause security incident, carrying out temperature monitoring to these bearings just can Timeliness coverage hidden danger, generation of preventing accident.These metal bearings are generally in the inside of equipment, and sight line is blocked and quantity is many, are difficult to realize by infrared measurement of temperature mode.And due to the reason such as high voltage, rotation, infeasible by temperature-sensitive galvanic couple, optical fiber temperature-measurement mode, therefore wireless monitor is optimal selection.
To the wireless temperature monitoring of metal bearing, its difficult point is in the following aspects:
One is that metal parts is very large for the impact of wireless signal.Such as in radio-frequency (RF) identification (RFID) field, anti-metal tag is a difficult point and study hotspot always.This is because metal is as good conductor, the tangential electric field on its surface is zero, and this can have a strong impact on the work of the antenna of metal surface, causes wireless reading distance closely even can not read out.
Two is that metal pair electromagnetic wave has and well blocks effect, if sensor is arranged on the side of metal shaft, blocking so due to metal shaft, can cause the shadow region of wireless signal, may not receive transducing signal at opposite side.
Three is very high to installation and maintenance requirement.The monitor be arranged on axle can not be given prominence to too much, can not introduce other hidden danger, in order to avoid affect equipment work because of installation.Safeguard and also require conveniently.
Summary of the invention
For the thermometric demand of these metal bearing parts such as dynamic/static contact, train axle, mechanical drive shaft of power switch cabinet, the present invention proposes a kind of temperature monitoring collar of passive and wireless.The advantages such as this collar has that applicable metal bearing is installed, completely passive (just can work without the need to battery), quorum sensing inhibitor are good, simple and reliable.
The collar of the present invention, it is characterized in that: the collar be divided into concentric outer, in, interior three layers, skin is semi-circular or spirality metal, and internal layer is cylindrical metal, and middle layer is the insulating supporting material comprising the temperature sensitive resonator of surface acoustic wave, impedance matching inductance capacitance; One termination inner layer metal cylinder of the temperature sensitive resonator of surface acoustic wave, the other end connects outer layer metal centre position by impedance matching inductance capacitance; The aperture of inner layer metal matches with the metal shaft that will install, and outer layer metal is wireless signal radiating layer, and its external diameter and girth are determined according to frequency of operation.
In order to protect outer layer metal, one deck insulating protective layer can be added outside outer layer metal layer.The metal cylinder of internal layer plays the effect with reference to ground, also can be substituted by installed metal shaft and omit.
The collar of the present invention, the metal of its ectonexine forms an antenna, under rational size design, can effectively receive and launch the wireless signal of the temperature sensitive resonator of surface acoustic wave, thus realizes the communication with external detection device.According to emulation and test findings, the radiation direction of this thimble structure perpendicular to collar axle center, and is uniform in all directions substantially.This illustrates when the collar rotates along with metal shaft, and the transmitting-receiving of wireless signal is impregnable, thus ensure that Signal transmissions is good,
The temperature sensitive resonator of surface acoustic wave is the temperature variant passive device of a kind of natural resonance signal, and its thickness can be some more at 1mm, the several millimeter of length and width.Can there is resonance in it, and after external drive is cancelled, discharge the electromagnetic signal of certain frequency under the electric magnetization signal of outside.Just temperature can be detected according to the signal frequency of its release and the relation of temperature.Because its work capacity comes from external drive, therefore do not need powered battery, thus greatly save volume, contribute to realizing miniaturization, decrease the impact on equipment as far as possible.
The collar of the present invention is a passive wireless temperature sensor in itself, but solves the wireless temperature test problems of metal shaft due to its special design, has the advantages such as volume is little, signal does not affect by metal shaft rotation, installation and maintenance aspect.Especially the thermometric of the objects such as power switch cabinet dynamic/static contact, train axle, lathe rotating shaft is applicable to.
Change temperature sensitive for surface acoustic wave resonator into SAW (Surface Acoustic Wave) resonator with quality loading blocks, just form passive and wireless vibration or the angular velocity monitoring collar.Thus as required, basis of the present invention realizes the detection beyond temperature.
If space allows, the temperature sensitive resonator of surface acoustic wave can change active wireless temperature or vibration detection circuit and battery into, thus forms active temperature or the vibration monitoring collar.Active advantage is that monitoring distance is far away.
Hereafter by the present invention is further illustrated with embodiment by reference to the accompanying drawings.
