Description
Technical field
The utility model relates to a kind of sensor, more particularly, relates in particular to a kind of light-sensitive array light shading type solid particle level sensor.
Background technology
At present, the technology of known solid small particles depth detection comprises ultrasound wave, and microwave is perhaps weighed.Ultrasound wave and microwave all are the total depths of knowing in advance container, by measuring the distance of body surface and sensor, calculate the accumulation height of solid small particles.In case can't learn the container total depth, perhaps container is too little, the solid small particles surface is too coarse, all can cause and can't normally detect.
Using weighing technology, is to know in advance the container size, also has corresponding particle density that weight is converted into the solid small particles accumulation degree of depth.In case can't learn the container size, or irregular container, can make the result of measurement that larger error is arranged.For the solid small particles of weight less than 100g, also need to use expensive precise weighing equipment.Especially the solid small particles accumulation degree of depth less than the detection in the 10cm scope in, more difficult Measurement accuracy.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of compact conformation, easy to use and measure accurately light-sensitive array light shading type solid particle level sensor is provided.
The technical solution of the utility model is achieved in that a kind of light-sensitive array light shading type solid particle level sensor, comprise support plate, be evenly equipped with along its length some light activated elements on the wherein said support plate, be provided with the data acquisition chip that is connected with the external control element circuit at support plate, described each light activated element is connected with the data acquisition chip circuit respectively, support plate in each light activated element outside is provided with light source, and the light that described light source sends can cover all light activated elements.
In the above-mentioned light-sensitive array light shading type solid particle level sensor, described support plate is comprised of perpendicular support plate and the horizontal support plate that is arranged on perpendicular support plate upper end, perpendicular support plate cooperates with horizontal support plate and is inverted L-shaped, described each light activated element is distributed on the perpendicular support plate along its length, and described light source is arranged on the horizontal support plate surface relative with erecting support plate.
In the above-mentioned light-sensitive array light shading type solid particle level sensor, described support plate is provided with data transmission interface, and described data transmission interface is connected with data acquisition chip, and described data acquisition chip is connected with the external control unit by data transmission interface.
In the above-mentioned light-sensitive array light shading type solid particle level sensor, described light activated element is photoresistance.
In the above-mentioned light-sensitive array light shading type solid particle level sensor, described light source is the LED lamp.
After the utility model adopted said structure, by photoresistance cooperated with LED lamp, the voltage that the photoresistance of not blocked by particle is exported was lower than threshold voltage, and the level signal that data acquisition chip receives is " 0 "; And the voltage of the part photoresistance that is blocked output is higher than threshold voltage, and the level signal that data acquisition chip receives is " 1 ".Data acquisition chip sends to the external control unit to the number of " 0 ", " 1 " by data transmission interface and processes, and by default process analysis, draws the accurate degree of depth of particle.The utility model is particularly useful for detecting the degree of depth less than the solid small particles of 10cm, and measuring accuracy is high, good stability, and antijamming capability is strong.The utlity model has little, easy to use, the advantage cheaply of accuracy of detection height, simple installation, volume.
