Concrete scheme of the present utility model is: narrow slit disk (1) is installed on the windlass concentric shafts (6) that detects material level.Narrow slit in the narrow slit disk (1) is wide to be the 1.5--3.5 millimeter; Length is the 10--35 millimeter; Interval 5--50 millimeter between narrow slit and the narrow slit.It is fixed that the diameter of narrow slit disk (1) and narrow slit bar number are come by windlass wireline drum circumference and Measurement Resolution.General measure resolving power is decided to be 1 centimetre.When the girth of wireline cylinder was 55 centimetres, the narrow slit bar number on the narrow slit disk (1) was decided to be 55.Photoelectric transformer (2) is by infraluminescence pipe (7), (8); Phototriode (9), (10); Current-limiting resistance (11), (12), (13), (14); Hex inverter (15) (having this schmitt trigger); Electric capacity (16) is formed.Photoelectric transformer (2) is fixed on the base by a U type support, respectively is provided with the threaded hole of an O 5mm on U type support both sides, and a screw is respectively arranged in the hole, screws the both sides screw photoelectric transformer (2) is fixed in the U type support.Intelligence level-sensing device (5) provides 9 volts of direct supplys for photoelectric transformer (2) by supply lead (4).9 volts of positive sources link to each other with the anode of infrared light emission pipe (7), (8) respectively by current-limiting resistance (11), (12).The negative electrode of infrared light emission pipe (7), (8) links to each other with power cathode.Positive source also links to each other with the collector electrode of phototriode (9), (10) simultaneously.The emtting electrode of phototriode (9), (10) links to each other simultaneously with the input terminus of two doors of hex inverter (15) respectively, and emtting electrode also links to each other with current-limiting resistance (13), (14) respectively.Current-limiting resistance (13), (14) the other end link to each other with power cathode.Electric capacity (16) and between the power positive cathode of hex inverter (15).Narrow slit in narrow slit disk (1) is by the groove of photoelectric transformer (2), phototriode (9), (10) conducting.Launch very high level, the signal of exporting by hex inverter (15) is a lower level.When narrow slit by behind the groove, end phototriode (9), (10), launches that very lower level is by hex inverter (15), the signal of output is a high level.Promptly produce a pulse.Because the running orbit of narrow slit is a circumference during narrow slit disk (1) rotation.So the difference on two limits of narrow slit is not to pass through groove simultaneously.Two groups of photoelectric switching circuits arranged side by side are arranged in the photoelectric transformer (2).Signal A, the B of two outs of phase have so just been produced.Narrow slit disk (1) is signal A phase lead signal B when just changeing.During counter-rotating, signal B phase lead signal A.Hex inverter (15) is by 9 volts of power supplies.Its output links to each other with optocoupler (17), (18) in the intelligent level-sensing device (5) by signal cable (3).Its effect of hex inverter (15) (having this schmitt trigger) is with signal reshaping.The elimination undesired signal.Electric capacity (16) strobes
Intelligence level-sensing device (5) is mainly by optocoupler (17), (18); 8098 SCM systems (19); LED luminotron warning light (20); LED charactron indicating meter (21); Standard signal output (22); Thin film switch formations such as (23).Optocoupler plays the signal buffer action.LED luminotron warning light (20) is made up of three LED luminotrons, is respectively applied for thanks to expect, collapse material, hanging warning.LED charactron indicating meter (21) is made up of 4 charactrons, is used to show the stockline value of material level.The unit of display is centimetre.Standard signal output (22) is converted to the stockline value electrical signal output of 4--20 milliampere or 1-5 volt.Thin film switch (23) is used for the setting of set(ting)value stockline.8098 SCM systems (19) are used to coordinate the work of each parts and the calculating of stockline, judgement of warning etc.The working process of this device is as follows:
When stock rod test windlass is just changeing is that narrow slit disk (1) just changes, and photoelectric transformer (2) produces wherein signal A phase lead signal B of two group pulse signal A, B.Otherwise propose narrow slit disk (1) counter-rotating on the stock rod, signal B ultrasonic front signal A in the two group pulse signals that photoelectric transformer (2) produces.Two paths of signals links to each other with 8098 SCM systems (19) by optocoupler (17), (18).Single Chip Microcomputer (SCM) program is discerned by the phase place of judging signal A and signal B and is carried on the stock rod or test.Calculate the stockline of blast furnace material level simultaneously by the umber of pulse of signal A.A pulse is represented one centimetre.The stockline value is shown by L E D charactron indicating meter (21).As stock rod test signal A phase lead signal B.Stockline increases.Carry signal B phase lead signal A on stock rod, stockline reduces.When stockline adds 0.2 meter greater than the set(ting)value stockline, expect that thanks to warning light is bright in the LED luminotron warning light (20).The set(ting)value stockline can be set at any time by thin film switch (23).If stockline is when descending greater than 1.2 meters/minute speed, in the LED luminotron warning light (20) to collapse the material warning light bright.When stockline when descending less than 0.005 meter/minute speed, the hanging warning light is bright in the LED luminotron warning light (20).When proposing or receiving spy on the stock rod, warning light extinguishes, and removes and reports to the police.Each stock rod is received when visiting, and system calibrates once stockline zero point automatically.
Owing to cancelled gear in the system, made precision and the reliability of measuring material level all improve.Photoelectric transformer (2) is directly exported the immunity from interference that digital quantity has improved whole detection system.Owing to used SCM system, made that this device circuit is simple, component number is few.Convenience all is provided for operation and maintenance.For requiring the high occasion of measuring accuracy, can improve measuring accuracy by the bar number that increases narrow slit in the narrow slit disk (1).The standard signal of intelligent level-sensing device (5) output (22) is linked to each other with the data collecting system of computer can be with blast-furnace line and material loading lot number record.Make operator in time adjust stockline by analyzing the stockline change curve, reduce the number of times of thanks to expecting, collapse material, hanging, improve system's direct motion and technico-economical comparison.
