The electric-control system of the utility model device as shown in Figure 3, the power supply that it is inner and control circuit all routinely power circuit and control circuit form:
Concrete application process is as follows:
Preset in program when survey cavity 9 be in n chute 20 directly over the time cross sliding clock 4 left ends upper ends to the left end of the distance L h1 between distance L n, left dislocation sensor 10 and the right displacement transducer 11 of left dislocation sensor 10, cross sliding clock 4 to the distance L h2 between distance L sp, top offset sensor 12 and the bottom offset sensor 13 of right-hand member, upright slide block 8 to the distance L sz of lower end, and when upright slide block 8 is in respectively lifting extreme position and sinking extreme position top offset sensor 12 detected distance L s
0And Lx
0, the numerical value of these distances can by actual measurement obtain and the database of write-in program in.
The ore pulp that various needs carry out constituent content analysis flows through from each self-corresponding chute 20 respectively, drive the forward or reverse of horizontal direction motor 2 by control box 21, drive horizontal screw bolt 3 forward or reverse, make cross sliding clock 4 and move horizontally dull and stereotyped 5 left lateral or right lateral, and by the testing result of left dislocation sensor 10, cross sliding clock 4 is positioned, guarantee cross sliding clock 4 and move horizontally flat board 5 that just surveying cavity 9 when stopping is positioned at directly over chute 20 to be analyzed.Then control box 21 drives 6 counter-rotatings of vertical direction motor, drive vertical screw rod 7 counter-rotatings, and by the testing result of top offset sensor 12, upright slide block 8 is positioned, make upright slide block 8 drop to the sinking extreme position, guarantee that the head of surveying cavity 9 is immersed in ore pulp.Instrument begins ore pulp is detected analysis.
After this time detects the analysis end, control box 21 drives vertical direction motor 6 forwards, drive vertical screw rod 7 forwards, and by the testing result of top offset sensor 12, upright slide block 8 is positioned, make upright slide block 8 rise to the lifting extreme position, guarantee that the head of surveying cavity 9 exceeds chute 20.Then control box 21 judges whether to continue other ore pulps are analyzed according to default program, if not finish measuring process, if had by the forward or reverse that control box 21 drives horizontal direction motors 2 make move horizontally dull and stereotyped 5 left lateral or right lateral to survey cavity 9 be positioned at chute 20 to be analyzed directly over the position, repeat said process.
In conjunction with Fig. 4, control procedure is described in detail:
After control system starts, at first by the detected distance to upright slide block 8 upper ends of top offset sensor 12, upright slide block 8 is positioned, judge whether to be in the lifting extreme position, concrete determination methods is: the Ls that establishes in advance in the distance L s that top offset sensor 12 detects and program
0Compare, if not promoting extreme position, control the rotation of vertical direction motor 6, and by the testing result of top offset sensor 12, upright slide block 8 is located, make upright slide block 8 be in the lifting extreme position; If upright slide block 8 has been in the lifting extreme position, directly enter next step cross sliding clock 4 is positioned, be that testing result by left dislocation sensor 10 realizes to the location of cross sliding clock 4.
then program validation is according to the chute 20 that is about in predefined measuring sequence measure, if and check from database and obtain making that when surveying cavity 9 and being in directly over this chute 20, cross sliding clock 4 left ends should be to the distance values Ln of left dislocation sensor 10, and the actual range Lz that further measured at that time with left dislocation sensor 10 compares, judgement by program, confirm cross sliding clock 4 should still move right left just can make survey cavity 9 be in this chute 20 directly over, and realize by the rotation of control box 21 control horizontal direction motors 2, concrete judgment mode is: if Ln＜Lz cross sliding clock 4 should be moved to the left, horizontal direction motor 2 is answered forward, if Ln＞Lz cross sliding clock 4 should move right, horizontal direction motor 2 should reverse, if Ln=Lz cross sliding clock 4 has arrived at desired location, horizontal direction motor 2 should stop operating.
When cross sliding clock 4 left lateral or right lateral to made survey cavity 9 be positioned at chute 20 to be measured directly over behind the position, control box 21 positions upright slide block 8 by the testing result of top offset sensor 12, and control 6 counter-rotatings of vertical direction motor and make upright slide block 8 drop to the sinking extreme position, namely work as Ls=Lx
0In time, controlled vertical direction motor 6 and stops operating, and the head that survey cavity 9 this moment immerses in ore pulp.Then instrument is analyzed beginning to the detection of this kind ore pulp.
When instrument, the detection of this kind ore pulp is analyzed finish after, control box 21 positions upright slide block 8 by the testing result of top offset sensor 12, and controls vertical direction motor 6 forwards and make and carry on upright slide block 8 to promoting extreme position, namely works as Ls=Ls
0In time, controlled vertical direction motor 6 and stops operating, and the head that survey cavity 9 this moment has exceeded above chute 20.
Program judges whether that the ore pulp of other chutes 20 need to continue to measure in addition subsequently, if have, by program validation according to the chute 20 of be about to measuring in predefined measuring sequence, and the forward or reverse of controlling horizontal direction motor 2 make survey cavity 9 be positioned at this chute 20 directly over, repeat said process; If do not need the ore pulp that continues to measure, whole process finishes.
In whole process, bearing accuracy to left dislocation sensor 10, right displacement transducer 11, top offset sensor 12, bottom offset sensor 13 judges, whole system is out of service when the location mistake occurring, and sends warning message, and concrete determination methods is as follows:
or think and the location mistake occurs if satisfy, wherein: Lh1 is the distance between left dislocation sensor 10 and right displacement transducer 11, Lsp is that the left end of cross sliding clock 4 is to the distance of right-hand member, Lz is the distance that left dislocation sensor 10 detects, Ly is the distance that right displacement transducer 11 detects, Lh2 is the distance between top offset sensor 12 and bottom offset sensor 13, Lsz is that the upper end of upright slide block 8 is to the distance of lower end, Ls is the distance that top offset sensor 12 detects, Lx is the distance that bottom offset sensor 13 detects, H1 and H2 are the micro-judgment parameter, L1, Lsp, L2, Lsz can obtain by the actual measurement to whole device, H1 and H2 can be according to the permission measuring error of sensor, permission mismachining tolerance and the correlation experience of device are determined.
