Embodiment is relevant for technology, means that the utility model adopted and reach effect, especially exemplified by preferred embodiment and cooperate diagram to be described in detail as follows, believe when can by must go deep into and concrete understanding.
Shown in Figure 1 is the utility model structural representation, and the circuit board 7 of high-pressure modular 1, sensor 2, sampling head 3, filtering silencer 4, pneumatic pump 5 and installation control circuit is installed in respectively on the base 6.Sampling head 3 adopts isokinetic sampling's head, sampling head 3 is assemblied in top, is sensor 3 below it, is pneumatic pump 5 below again, the bottom of sampling head 3 links to each other with the admission piece of sensor 2, and the admission piece junction of the bottom of sampling head 3 and sensor 2 is connected to the entrance point of pneumatic pump 5 by pipeline.High-pressure modular 1 is connected to the multiplier tube of sensor 2, provides a high pressure to multiplier tube, makes the multiplier tube can operate as normal.Pneumatic pump 5 is drawn into sensor 2 with air from sampling head 3, is drawn into the air that comes by 2 pairs of sensors and analyzes, thereby measure the number of dust particle in the air.Pneumatic pump 5 adopts 2.83L/MIN's, and the pipeline that pneumatic pump 5 has a flexible pipe to make is connected to the entrance point of pneumatic pump 5, and these parts have constituted the air sampling test section.
The endpiece of pneumatic pump 5 connects a soft pipeline to filtering exhaust box 4, and this is the assembling of system's self-cleaning part.In order to make sample data more accurate, that detect more accurate, before system carries out air sampling, after earlier the air in the pneumatic pump 5 being carried out the air self-cleaning and filter by filtering silencer 4, carry out the sampling of air sample again, in the present embodiment, the filtration particle diameter of filtering silencer 4 reaches 0.2 micron.
High-pressure modular 1 model is selected CC228-01Y for use, and its effect is to provide high-tension operating voltage for the laser multiplier tube in the sensor 2.
Fig. 2 is the utility model control circuit theory diagram, the input end of control circuit links to each other with high-pressure modular 1, the LASER Light Source that employing is sent by semiconductor laser, this semiconductor laser has characteristics such as volume is little, stability is high, the life-span is long, normal be made of one the composition sensor with test chamber and photodetector.Send beam of laser from semiconductor laser, sampled air is passed through from this Shu Jiguang, when airborne dust particle passed through the light beam of laser, scattering will take place in laser beam, formed light pulse signal.The intensity of this light pulse signal can change along with the variation of dust particle surface area, by photelectric receiver this light pulse signal is received and comes to convert to electric signal.The electric signal that comes out from photelectric receiver is admitted to prime amplifier and tentatively amplifies, and the electric signal that again this was tentatively amplified is sent into main amplifier and amplified once more afterwards.Electric signal after the amplification enters comparer subsequently, and these signals will be compared with some specific values in comparer, thereby tells the power of these signals.Comparer can become different digital signals to send in the counting circuit these conversion of signals according to the degree of signal power, and counting circuit carries out accumulated counts respectively according to different digital signals, and the result after adding up sends into central processing unit.Central processing unit becomes the RS-485 signal to be uploaded to computer these data-switching, by computer these signals is received and comes and convert corresponding data to realize functions such as demonstration, storage, control on computers.
