Background technology:
Tradition aeolian vibration monitoring method is for monitoring the deflection of wire clamp outlet 89mm place power transmission line through the use cantilever beam sensor; Cantilever beam sensor one end is fixed on the wire clamp; The other end contacts with power transmission line; The power transmission line vibration is directly exerted pressure and is given cantilever beam sensor, exports and the linear semaphore of deflection behind the cantilever beam sensor pressurized, calculates amplitude, frequency and other movable informations of aeolian vibration through the acquired signal amount.When adopting cantilever beam sensor in use; The rigid body portion of sensor is constantly deformed and fatigue; And high to the contact point requirements of tightness of semi-girder and power transmission line when mounted, too gently then there is gap error, cause then too closely that cantilever beam sensor deforms when not shaking.
Development along with CCD/CMOS and other optical flame detector spares; Very ripe on according to permutation technology regular in certain to the light sensation device; Like line array CCD/CMOS, area array CCD/CMOS is perhaps according to other regular arrangements; The density of arranging can cause different measuring accuracy; The light source projects of utilizing specific direction comes the judgement of amount to confirm the position of light projection through CPU to sensitization on the light sensation device on CCD or the orderly light sensation device of arranging of other known regimes, and the position of in known regimes, throwing according to light can obtain the movable information of light source.It is simple to adopt this method to install, and measured value is accurate, and the vibration frequency that can monitor is high.
Summary of the invention:
The objective of the invention is to overcome the shortcoming of above-mentioned prior art; A kind of method of monitoring aeolian vibration is provided; This method calculates amplitude-frequency and other movable informations of aeolian vibration through making the sensitization on the light sensation device of arranging in order according to known regimes of specific direction light source through judging the displacement of light source on the light sensation device.
The objective of the invention is to solve through following technical scheme:
A kind of monitoring method of aeolian vibration, (1) is fixed on light source on the power transmission line, the fixing light sensation device of arranging in order in light source the place ahead; The light that light emitted is gone out only is radiated at the direction of light sensation device;
(2) on the light sensation device, be connected with collection arithmetic element and communication unit; Through gathering arithmetic element the irradiation position of light source on the light sensation device judged in the calculating of light sensation device sensitive volume; Light source calculates the amplitude of aeolian vibration at irradiates light sensor spare diverse location, frequency and other movable informations during according to vibration.
Said light sensation device, collection arithmetic element and communication unit are fixedly mounted on the power transmission line through wire clamp.Said light sensation device is arranged in order.Said light source is a directional light sources.Said light sensation device is arranged on the wire clamp mouth, and the distance of this light sensation device and light source is 89mm.
A kind of monitoring device of aeolian vibration comprises light source, light sensation device, gathers arithmetic element and communication unit, and this light source is fixedly installed on light sensation device the place ahead, is connected with on the light sensation device and gathers arithmetic element and communication unit;
Said light sensation device, collection arithmetic element and communication unit are fixedly mounted on the power transmission line through wire clamp;
Be installed with bracing or strutting arrangement on the said power transmission line, light source is fixed on the power transmission line through this bracing or strutting arrangement;
Said light sensation device is arranged on the wire clamp mouth, and the distance of this light sensation device and light source is 89mm;
Said light sensation device is arranged in order; Said light source is a directional light sources.
The present invention has following advantage:
1. precise monitoring owing to use optical sensor, has linear array or dot matrix CMOS/CCD now and has reached very high integrated level, and the CCD/CMOS of employing 14um point distance is enough to the measurement of aeolian vibration.
2. be prone to install, use cantilever beam sensor relatively, it is simple to adopt method involved in the present invention to install, and does not exist in the mechanical measurement high to the accuracy requirement of installing.
3. but the monitoring vibration frequency is high, and existing CMOS/CCD frequency is up to 20Mhz, and aeolian vibration 150hz width monitoring is required can be satisfied fully.
