A sensor composed of a metal detection polar board, a chip selection switch circuit and a single-chip microcomputer component is adopted and the change of circuit conduction is detected through the single-chip microcomputer control component according to the different conduction characteristics of a saline solution and a saline crystal, so that fixed point continuous automatic detection of the crystallization thickness of the saline solution is achieved, the purpose that the saline solution crystallization process is mastered is achieved, and the change of the thickness of a crystallization layer can be effectively and accurately measured.
Description
Technical field: the present invention relates to a kind of salt solusion crystallization thickness automatic detecting device, belong to an invention in test technique automatic field, it is a kind of device that can carry out to salt solusion the detection of crystallization thickness fixed point Automatic continuous.
Technical background: the salt solusion crystallization thickness detection technique of domestic and international application still adopts the direct method of measurement at present, it relies on the artificial crystallization thickness of directly measuring, its advantage is that data are reliable, but it is low that shortcoming is automaticity, can not ensure detect or synchronously carry out robotization continuous detecting in many places at same place self-timing, so there is no so far the Automatic continuous acquisition methods of complete crystallization process delta data.The present invention has succeeded in developing a kind of conductance circuit that utilizes and crystallization thickness has been carried out to the detection method of automatically measuring.
Summary of the invention: the invention provides a kind of salt solusion crystallization thickness automatic detecting device.Salt solusion crystallization thickness transducer is by U-shaped plastic-steel material cylinder, is embedded in inner side, U-shaped plastic-steel cylinder left and right and arranges metal detection pole plate group, the sheet of equidistant installation and select on-off circuit, capacitive frequency change-over circuit, singlechip controller to form.Metal detection pole plate group selects on-off circuit, capacitive frequency change-over circuit to be connected with singlechip controller by sheet.The different conductance properties that present according to air, solution, crystalline solid, realize the fixed point continuous automatic inspection to salt solusion crystallization thickness in conjunction with electronic information treatment technology, reach the object of real-time grasp salt solusion crystallization process, can effectively and exactly measure the variation of crystallizing layer thickness.
Brief description of the drawings: Fig. 1 is system construction drawing, and salt solusion crystallization thickness automatic detecting device of the present invention is by U-shaped plastic-steel material cylinder, is embedded in inner side, U-shaped plastic-steel cylinder left and right and arranges metal detection pole plate group, the sheet of equidistant installation and select on-off circuit, capacitive frequency change-over circuit, singlechip controller to form; Metal detection pole plate group selects on-off circuit, capacitive frequency change-over circuit to be connected with singlechip controller by sheet; Metal detection pole plate group is equidistant is embedded in the left and right equidistant arrangement in inner side of U-shaped plastic-steel cylinder, and metal detection pole plate composition is to occurring, and left and right correspondence.U-shaped plastic-steel material cylinder both sides are hollow, both sides hollow position built-in metal Detection electrode group circuit, and sealing.
Embodiment: pick-up unit is vertically placed in salt solusion, and U-shaped plastic-steel material cylinder overall height is greater than solution height, and part metals Detection electrode is exposed on salt solusion, and underlying metal Detection electrode group is submerged in salt solusion; Single chip machine controlling circuit produces switch controlling signal by certain coded sequence, makes at any time sheet select on-off circuit upwards to connect wherein pair of metal Detection electrode from bottom successively according to coded sequence, and single-chip microcomputer detection circuit judges that it belongs to crystalline solid or liquid; Singlechip controller will be determined tested metal detection pole plate belonging positions according to coding corresponding to this moment simultaneously, after all neighbouring metal detection pole plates detections loop all being detected under the control of single chip machine controlling circuit, single-chip microcomputer can be determined the boundary position of solution and crystalline solid, and then Automatic continuous is determined the thickness of crystalline solid.
Beneficial effect: the different conductance properties that air, solution, crystalline solid presented according to salt solusion, crystalline solid, utilize testing circuit, develop a kind of salt solusion crystallization thickness transducer and a kind of new salt solusion crystallization thickness detecting method in conjunction with electronic information treatment technology.Utilize this sensor and detection method can realize the fixed point continuous automatic inspection to salt solusion crystallization thickness, reach the object of grasping salt solusion crystallization process, the variation that can effectively and exactly measure crystallizing layer thickness.
