Description
Technical field
The utility model relates to electrical technology, specifically relate to a kind of under high-intensity magnetic field, high dust, deep-etching, the touch switch device that various manual input signals use.
Background technology
Domestic large-scale pre-baked aluminum electrolysis cell production series generally uses slot control machine that the various actions of electrolysis tank is controlled automatically.The performance of slot control machine at first is the safety that guarantees electrolysis tank and whole electrolytic series.Because in large-scale pre-baked aluminum electrolysis cell was produced, potline current was generally all more than 160KA, if slot control machine is out of control, cause the electric tank cathode anode to open circuit, blast accident, serial blast accident will cause whole electrolysis production series to stop production, and economic loss will be very heavy.The hardware systems of the first generation slot control machine that China produces is based on the single board computer of STD bus technology, and adopts board plug type mechanism, centralized control.The subject matter that this class slot control machine exists in design is: hand switch (input signal) adopts the mechanical type of push-button switch and toggle switch, and its mounting means is that screw is fixed on the guidance panel.Its structure mainly is the spring reset that the contact is arranged, and mechanical switch is by operating the break-make of direct current signal manually.Under the high dust of electrolysis, deep-etching, strong magnetic field circumstance, very easily produce can not reset certainly, stuck phenomenon.If the mechanical switch phenomenon that can not reset takes place, just may cause the electric tank cathode anode accident that opens circuit when rising anode (or rise resistance lift voltage).In this,, slot control machine degree of integration was low in generation, use nearly tens of circuit board quantity, signal path switching link (plug connector) connecting line and contact point are too many, the subject matter of bringing to equipment running process is: the easily oxide etch in the environment of the on-the-spot deep-etching of electrolysis, high-intensity magnetic field, high dust of joint plug-in unit, cause loose contact, signal interruption and initiation random faule, the fail safe of complete machine, stability, reliability are lower; Require the high maintenance difficulty big to maintenance technology; The maintenance cost height of spare part acquisition expenses and system.
The SCM Based distributed control slot control machine of second generation slot control machine has solved the problem that first generation slot control machine centralized control separate unit slot control machine can not independent operation, and hand switch (input signal) still adopts mechanical switch.
Third generation slot control machine is based on the distributed control slot control machine of CAN bus, and printed circuit board (PCB) is few, and every impact of performance has all obtained increasing substantially.But the manual ringing soft-touch control that is used for the environment of deep-etching, high-intensity magnetic field, high dust, the Shang Weijian record.
The utility model content
The technical problems to be solved in the utility model is the deficiency that exists at prior art, and a kind of touch switch device that adapts to high-intensity magnetic field, deep-etching, high dust atmosphere is provided.
The touch switch device that the utility model adapts to high-intensity magnetic field is achieved by following technical proposals: the touch switch device that the utility model adapts to high-intensity magnetic field is by comprising that the switch that the metal nuts touch point N1 that is installed on the control panel and capacitor C 11 constitute touches circuit, the oscillator of output square wave, NOR gate circuit, current rectifying and wave filtering circuit, inverter and output circuit constitute, and described oscillator output end is through two resistance R
11, R
12Connect on two input 5 pin and 6 pin of XOR gate, the switch that is made of touch point N1 and capacitor C 11 touches input 6 pin that circuit connects XOR gate, output 4 pin of XOR gate connect the current rectifying and wave filtering circuit that is made of capacitor C 12, C13, diode D12, D13 and resistance R 13, rectification filter circuit output end connects inverter ic 5C input 5 pin, inverter ic 5C output 6 pin sending and receiving optical diode D13, light-emitting diode D13 output connects the next stage input port by connection-peg output.
The touch switch device that the utility model adapts to high-intensity magnetic field compared with prior art has following beneficial effect: because the utility model adopts metal nuts as the touch point, overcome contact switch easy defective of oxide etch and loose contact in the environment of high-intensity magnetic field, high dust, deep-etching, overcome the disadvantage that conventional induction type touch switch can not stable operation in the environment that the power frequency component of strong electromagnetic field disturbs, this external enwergy realizes the auto-reset function of on off state.The utility model switch performance is reliable and stable, has from reset function, does not have the easily stuck phenomenon of mechanical switch, can the switch adhesion.The more important thing is at the high-intensity magnetic field power frequency component and disturb under the industrial environment of big, deep-etching, high dust that the various signals of output are interference-free, signal stabilization is reliable.Avoid switch not reset simultaneously or the switch adhesion causes slot control machine input signal mistake and the electric tank cathode anode that causes opens circuit the accident of blasting, serial blast accident; Normal crust breaking, blanking, anode lifting can't be carried out when having avoided fault, abnormal conditions such as anode effect processing can't be in time carried out.The utility model is applicable to the transformation of aluminium electrolysis enterprise slot control machine control system operation panel.
