Description
Technical field
The present invention relates to field of advertisement spotting, particularly relate to a kind of underground tunnel advertisement player method based on photoelectric sensor.
Background technology
Photoelectric detecting method has the advantages such as precision is high, reaction is fast, noncontact, and it is many to survey parameter, and the structure of sensor is simple, and flexible form is various, and therefore, electro-optical pickoff is applied widely in detection and control.
Photoelectric sensor is the key element realizing opto-electronic conversion in various photodetector system, and it is device light signal (infrared, visible and ultraviolet laser light) being transformed into electric signal.
Electro-optical pickoff is the sensor using photoelectric device as conversion element.It can be used for detecting the non electrical quantity directly causing light quantity to change, as light intensity, illuminance, radiation temperature measurement, gas composition analysis etc.; Also can be used to detect can convert to light quantity change other non electrical quantities, as diameter of part, surfaceness, strain, displacement, vibration, speed, acceleration, and the shape of object, the identification etc. of duty.Electro-optical pickoff has the features such as noncontact, response are fast, dependable performance, therefore in industrial automation arrangement and robot, obtains widespread use.New photoelectric device continues to bring out, particularly the birth of ccd image sensor, for new page has been started in the further application of photoelectric sensor.
Diversified by luminous flux to the optics TT&C system made by the action principle difference of photovalve, two classes can be divided, i.e. analog photoelectric sensor and pulse (switch) formula photoelectric sensor by photovalve (optics TT&C system) output quantity character.
Analog photoelectric sensor converts continually varying photocurrent to by measured, it and measured between in single valued relation.Analog photoelectric sensor can be divided into transmission (absorption) formula, diffuse reflection type by measured (detection target object) method, light shading type (light beam resistance shelves) three major types.
So-called transmission-type refers to that testee is put in the optical path, and the luminous energy that permanent light source sends is through measured object, and after part is absorbed, transmitted light projects on photovalve; So-called diffuse reflection type refers to that the light that permanent light source sends projects on measured object, then projects photovalve after testee surface reflection; So-called light shading type refers to that the luminous flux sent when light source hides wherein a part of through tested object light, and the luminous flux projected on photovalve is changed, and the degree of change is relevant in light path position with testee.
Energy-saving and emission-reduction are exactly economize energy, reduce energy resource consumption, the discharge of decreasing pollution thing.Energy-saving and emission-reduction comprise energy-conservation and reduce discharging two large technical fields, and the two is related, and has any different again.Generally speaking, energy-conservationly must to reduce discharging, and reduce discharging may not be energy-conservation, so reduction of discharging project must strengthen the application of power-saving technology, the energy consumption caused to avoid reducing discharging result because coveting is increased sharply, and focuses on social benefit and environmental benefit is balanced.
China's economy increases fast, and every construction obtains great achievement, but has also paid the cost that huge resources and environment is destroyed, and the contradiction between both is increasingly sharp-pointed, masses' environmental pollution strong reaction.This situation and irrationality of the economic structure, extensive pattern of economic growth are directly related.Do not accelerate to adjust economic structure, growth pattern transformation, resource fork is unable to hold out, and environment does not hold, and society holds and dares not accept, and economic development is hard to carry on.Only adhere to saving development, Clean Development, security developments, could sound and rapid economic growth be realized.Meanwhile, greenhouse gas emission causes global warming, enjoys international community's extensive concern.Further reinforcement energy-saving and emission-reduction work, be also reply Global climate change in the urgent need to.
Current, realize the situation that target for energy-saving and emission-reduction faces very severe.Since 2006, the whole nation from the leadership to the masses strengthens energy-saving and emission-reduction work, and State Council has issued the decision strengthening energy conservation, has formulated a series of policies and measures promoting energy-saving and emission-reduction, each department, all departments have made work arrangements in succession, and energy-saving and emission-reduction work achieves positive progress.But the whole nation did not realize the target of the energy-saving and cost-reducing and pollution emission reduction determined the beginning of the year in 2006, increase the difficulty of 4 years energy-conservation emission reduction works after Eleventh Five-Year Plan.More severe is, the first quarter in 2007, industry particularly highly energy-consuming, high pollution industry increase too fast, account for the electric power of national industrial energy consumption and sulfur dioxide (SO2) emissions nearly 70%, iron and steel, coloured, the large industry growth by 20.6% of building materials, petroleum refining, chemical industry etc. six, accelerate 6.6 percentage points on year-on-year basis.Meanwhile, still there is the problems such as understanding is not in place, responsibility is indefinite, measure does not match, policy imperfection, input are not implemented, coordination is incapable in various work.This situation is as reversed not in time, and not only energy-conservation emission reduction work in 2007 is difficult to make great progress, and the overall goal of Eleventh Five-Year Plan energy-saving and emission-reduction also will be difficult to realize.
Rational utilization of electricity, using electricity wisely, and be the most important thing that electric energy has become in energy-saving and emission-reduction work by some discarded energy conversions.The giant mechanical and electrical equipment of a lot of industrial and mining enterprises is because the reason of explained hereafter also exists serious power consumption phenomenon, its power saving rate when not affecting normal production after professional reducing energy consumption mostly more than 20%, numerous industrial and mining enterprises of comprehensive country this will be a huge energy wealth.In addition, a lot of communal facility can be considered economize on electricity such as the advertisement in subway tunnel.
Advertisement in subway tunnel is arranged on the visible angle of every individual advertisement picture of width in tunnel wall by restriction, when train high-speed motion, make to be arranged on picture in tunnel wall with the relatively-stationary position of passenger on flash fast one by one, thus make passenger experience animation effect.
Advertisement in existing subway tunnel is all generally open for a long time during metro operation, when there is no subway process in tunnel, and a kind of waste of electric energy beyond doubt.
