Abstract
The invention provides a surface acoustic wave wireless sensor solution aimed at a complex object to be detected. According to the surface acoustic wave wireless sensor solution aimed at the complex object to be detected, the surface acoustic wave wireless sensor is suitable for being used under the condition that the space is narrow, and metal blocking or rotating members exist. The solution is characterized in that a surface acoustic wave wireless sensor piece of a sensor and an antenna of the sensor are arranged on different positions of a motor respectively, wherein the surface acoustic wave wireless sensor piece is arranged on a position to be detected through a special structural member, the antenna of the sensor is installed on another position where a wireless signal is easy to receive and send, and the surface acoustic wave wireless sensor piece is connected with the antenna through a radio frequency coaxial cable.
Description
Technical field
The present invention relates to sensor field, particularly relate to the structural design of surface acoustic wave sensor.
Background technology
Surface acoustic wave wireless sensor without the need to powered battery, but works by the inquiry electromagnetic signal energy that absorbs collector, and this has unique advantage under high temperature, high voltage and the occasion that has higher requirements to maintainability.So more and more approved in power equipment thermometric surface acoustic wave wireless temperature sensor recent years (being passive wireless temperature sensor again).
But surface acoustic wave wireless sensor is due to not charged pool, its signal very weak (signal intensity only has the magnitude of 1,000,000/milliwatt), therefore require higher to the performance of antenna and installation site.The antenna of General Requirements sensor has the distance of larger size, receiving antenna and sensor to want near, and position and direction need to meet certain requirement just can reach good effect.When running into tested position narrow space, there is metal object to block or be in the situation of rotation status, being difficult to obtain good effect.But the tested position of such complexity is majority of case in Practical Project, the surface temperature measurement etc. of the static contact of such as power switch cabinet, moving contact, cylinder.
Summary of the invention
The present invention proposes a kind of surface acoustic wave wireless sensor solution for complicated measured body, be suitable for that surface acoustic wave wireless sensor is used for narrow space, have metal to block or the situation such as rotary part.
The solution that the present invention proposes, it is characterized in that: the surface acoustic wave sensor part of sensor and antenna are arranged on different positions respectively, wherein surface acoustic wave sensor part is arranged on tested position by application specific architecture part, and the astronomical cycle of sensor is in other position being easy to wireless signal transmitting-receiving, be connected by radio frequency coaxial cables therebetween.
By such method, the quality of surface acoustic wave wireless transducing signal can either be ensured, surface acoustic wave wireless senser element can be made again to be arranged on the position needing most detection, thus obtain more genuine and believable measured data.
Hereafter by the present invention is further illustrated with embodiment by reference to the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is the scheme schematic diagram detecting motor rotor winding temperature by surface acoustic wave wireless thermometric mode.
The title of accompanying drawing each several part is: 1, motor outer cover; 2, rotor; 3, rotor bearing; 4, SAW Temperature Sensors part; 5, radio frequency coaxial cables; 6, cable wiring hole; 7, SMA radio-frequency joint flange; 8, sensor antenna; 9, reading antenna; 10, the radio frequency coaxial cables of collector is connect.
Embodiment
Fig. 1 is the scheme schematic diagram detecting motor rotor winding temperature by surface acoustic wave wireless thermometric mode.Method according to routine just needs at generator sensor installation antenna and reading antenna, and this is spatially unallowed.And rotor is in high-speed rotation state, the distance acute variation between sensor antenna and reading antenna, thus cause wireless signal suddenly big or suddenly small, have impact on stable thermometric exactly.And adopt the method shown in Fig. 1 just can address this problem.
According to Fig. 1, SAW Temperature Sensors part (4) is installed in the position that rotor (2) winding the most easily generates heat, and sensor antenna (8) is then arranged on the rotor bearing (3) of motor outer cover (1) outside.Connect SAW Temperature Sensors part (4) and the RF cable (5) of sensor antenna (8) to be embedded in the poor and rotor (2) in the hole of rotor bearing (3).Reading antenna (9) is also fixed on motor outer cover (1), and keeps rational angle and distance with the antenna (8) of sensor.
According to the installation method of Fig. 1, harsh requirement be there is no to the size of sensor antenna and reading antenna, and be easy to keep suitable Distance geometry relative angle, thus ensure intensity and the quality of wireless sensing signal.No matter motor how high-speed rotation, always the Distance geometry relative angle of sensor antenna and reading antenna remains unchanged, avoid and cause signal suddenly big or suddenly small because rotate.
Above example is used for illustrative purposes only, but not limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, various conversion or modification can also be made, therefore all equivalent technical schemes also should belong to category of the present invention, should be limited by each claim.
