Description
Technical field
The present invention relates to data monitoring technical field, more particularly to a kind of passive data acquisition terminal, optical controller and it is
System.
Background technology
Substantial amounts of high-tension switch cabinet is provided with electric process, power transmission and transformation system in order to more preferably more easily control transmission of electricity, become,
The stable operation of high-tension switch cabinet has very important meaning for power system.Switch contact is contacted not in switch cubicle
Good, connector loose contact, poor wire connection or insulation ag(e)ing, can cause the generation of the phenomenons such as heating, the starting the arc, finally cause
Switch cubicle operation troubles.Excess temperature is also the main phenomenon before switch cubicle failure, passes through the operation temperature of equipment in monitoring switch cabinet
Degree, can effectively prevent the generation of failure.
Switch cabinet temperature monitor mainly has four kinds of technologies at present：
1) surface acoustic wave thermometric：Temp measuring system is main by surface acoustic wave wireless temperature probe (sensor) and former based on radar
The temperature reader composition of reason.Its course of work is：Reader sends electromagnetic scanning signals, and probe receives electromagnetic wave signal simultaneously
The surface acoustic wave of its internal work is converted into by interdigital transducer；Surface acoustic wave is converted into electromagnetic wave signal through interdigital transducer again
Reader is returned to via antenna；The propagation characteristic of surface acoustic wave and the linear characteristic relation of temperature, so that what probe was returned
Echo-signal has temperature profile；Reader extracts the electromagnetic wave signal feature that probe is returned, with regard to that can obtain temperature information, so that
Realize wireless and passive temperature monitoring.
2) infrared measurement of temperature：All temperature are all ceaselessly sending infra-red radiation higher than the object of absolute zero to surrounding space
Energy, the size of infrared energy has very close relationship by the distribution of wavelength and the surface temperature of testee, because
This, by the measurement of the infrared energy sent to object itself, just can accurately measure its surface temperature.
3) fibre optic temperature sensor：The macromolecule that fibre optic temperature sensor is matched using a kind of and optical fibre refractivity is temperature sensitive
Material is coated in two outside of fiber being welded together, and luminous energy is inputted the reflecting surface by an optical fiber defeated from another optical fiber
Go out, because this novel temperature-sensitive material is affected by temperature, refractive index changes, therefore the luminous power and temperature of output are in function
Relation.
4) conventional temperature-measurement approach sensor：Using the sensor of usual manner thermometric, to increase isolation features, using wireless
The mode of communication, in order to obtain power supply, there is two ways at present：1. way to take power is sensed：Sensing power taking can be become by temperature
Change, pressure, solar energy, electric current power taking etc.；2. battery power supply mode.
In process of the present invention is realized, inventor has found that at least there are the following problems in the prior art：
1) surface acoustic wave thermometric：Surface acoustic wave can realize passive and wireless thermometric, this spy using the physical characteristic of device
Property it is simultaneously also sensitive to displacement and vibrations, so higher to commissioning requirements in use, and be accomplished by within a period of time correcting, separately
Outer surface acoustic wave uses monocrystal material, and manufacture craft precision prescribed is high, and condition is more harsh, causes the high expensive of manufacture.
2) infrared measurement of temperature：Infrared measurement of temperature implementation is simple, and cost is low, but it is difficult to there are some in switch cubicle application
Topic, the wiring of switch cubicle, terminal, contact is not what is be completely exposed, there is many shelters, so installing infrared measurement of temperature equipment
Difficulty is larger.
3) optical fiber can realize large area thermometric, but its cost is higher, and in longtime running, due in switch cubicle simultaneously
It is not completely enclosed space, the inside has some dusts, and these dusts, which fall on optical fiber surface, can reduce the insulating capacity of optical fiber,
Cause even more serious accident.
4) conventional temperature-measurement approach sensor：1. way to take power is sensed：Sensing power taking can be by temperature change, pressure, too
Positive energy, electric current power taking etc..In switch cubicle, temperature, pressure change less, and it is unstable change, so having no idea
Stable acquisition energy, inside switch cabinet can not obtain solar energy.By the shadow of complexity change by way of electric current power taking
Ring than larger.2. by battery electricity-taking, power more stable, but need periodic replacement battery, switch cubicle needs to have a power failure, still
Switch cubicle interruption maintenance is not random, so it is than larger problem to change battery.
