Embodiment
With reference to Fig. 1, the utility model is made up of light data monitoring terminal (ODU), the two large divisions of Surveillance center.ODU is installed in the power transmission and transforming equipment scene, and its function is the collection of on-the-spot filthy data, and signal Processing and signal transmit.The function of Surveillance center is to receive the data-signal that ODU sends, and carries out integrated data processing then, obtains the various parameter values of every day, and is depicted as various curves.The relation curve of the salt dirt of every day, ash dirt, humidity, temperature and time etc.
Laser sensor is by lasing light source LD, light sensing element quartz glass bar BL, coupled fiber bundle GL
1, GL
2, GL
3, photoactor PIN
1, PIN
2, laser driver DR, equivalent process device SP etc. partly form.BL is the circular ring type quartz pushrod, and the size of circular diameter is corresponding with the insulator size, and the diameter of rod is 4 millimeters.The coupled fiber bundle is made up of thousands of optical fiber, and major function is to finish LD → BL, BL → PIN
1, LD → PIN
2Optically-coupled, should reduce the loss between them as far as possible, the function of SP is to adjust effective sensing area of optical sensor components, makes it the contamination process equivalence with insulator, DR is the input current that a high stable is provided to light source LD, thereby guarantees the high stability of LD Output optical power.
With reference to Fig. 3, according to the principle that light transmits in medium, when light transmits by quartz glass annulus BL, owing to the refractive index of air refraction less than quartz glass, luminous power will be limited in the quartz glass internal transmission, and the decay of luminous power is very little, can ignore; Filthy 2 the time when being attached with on the quartz glass annulus, because filthy refractive index is greater than the refractive index of quartz glass 1, some light can transmit from the filthy surface of adhering to, and promptly light is outwards revealed the loss that causes luminous energy herein, i.e. luminous power transmission is decayed.Along with increasing of filth, the luminous power transmission attenuation is just big more.Therefore, the variation of the damping capacity by detecting the luminous power transmission promptly can be known and adhere to what of the dirty density of salt on the quartz glass annulus.
With reference to Fig. 1,2, the laser power that is produced by LASER Light Source LD is divided into two-way: the one tunnel through GL1, BL, SP, GL3, PIN
1The filthy data of collection site, and be electric signal with converting optical signals, then through A1, A2 is amplified to the amplitude of requirement, delivers to 13 pin of multidiameter option switch SK (HC4051).Another road is through GL2, and PIN2 is converted to electric signal, and through A3, A4 is amplified to the amplitude of requirement, delivers to 14 pin of multi-way switch SK, and it is as the comparison signal of first via signal.This two paths of signals is sent into A/D (AD654) 4 pin with the different time from 3 pin of SK and is carried out analog to digital conversion, sends into processor of single chip computer MCU (C52) 15 pin then and carries out signal Processing.
Because the integrated data processing of Surveillance center also should be considered the influence to light signal of humidity and temperature, so also used humidity sensor SD and temperature sensor WD.On-the-spot humidity and temperature sensor signal are delivered to 12,15 pin of multidiameter option switch SK (HC4051) through A5 behind the A6 amplifier, make signal Processing by delivering to single-chip microcomputer MCD with above-mentioned same method again.Single-chip microprocessor MCU is with each parameter in every Monitoring Data.Be deposited into storer MC (4XAT24C512) as signals such as monitoring time, amount of laser light, luminous flux, humidity, temperature according to the combination of 16 systems, under the control of timing system TC (4013), regularly the data of being stored are delivered to communication interface (MAX232) sends to Surveillance center through gsm module (CS2000) to single-chip microcomputer.ODU finishes the collection of the on-the-spot filthy data of timing of system under the control of timing system TC, signal Processing and signal transmit.
Surveillance center carries out integrated data processing after receiving the data-signal that ODU sends, and obtains the various parameter values of every day, and is depicted as various curves, as the relation curve of the salt dirt of every day, ash dirt, humidity, temperature and time etc.
