The model utility content
The technical problem that the utility model solved is to provide a kind of clutch redundancy control device of reliable operation.
The technical solution that realizes the utility model purpose is: a kind of clutch redundancy control device comprises rotating coder, high speed counting module, PLC PLD, man-machine interaction interface, safety type auxiliary reclay, clutch duplex solenoid valve; Described rotating coder is connected with the bent axle of device to be measured by coupling, thereby follow crankshaft operation and its angle of swing is converted to electrical pulse, the PLC PLD is connected with rotating coder by high speed counting module, receive the rotary angle signal that detects, the PLC programmable logic device drives two safety type auxiliary reclays, two safety type auxiliary reclay difference solenoidoperated cluthes duplex solenoid valves, the contact series connection of two safety type auxiliary reclays outputs signal to the PLC PLD, thereby as can be known this moment two safe auxiliary reclays working state, form redundant self check loop; Described man-machine interaction interface is connected with the PLC PLD, reflects the working state of clutch in real time.
The utility model compared with prior art, its remarkable advantage: the utility model has made full use of the existing hardware resource of powder compacting lathe, simple in structure, stable performance, reliable operation, can effectively prevent from the misoperation that causes because of clutch duplex solenoid valve failure to allow clutch duplex solenoid valve be in safe Redundant Control.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is that clutch redundancy control device hardware of the present utility model constitutes schematic representation.
Fig. 2 is the utility model clutch redundancy controlling method flow chart.
Embodiment
In conjunction with Fig. 1, a kind of clutch redundancy control device of the present utility model comprises rotating coder, high speed counting module, PLC PLD, man-machine interaction interface, safety type auxiliary reclay, clutch duplex solenoid valve; Described rotating coder is connected with the bent axle of device to be measured by coupling, thereby follow crankshaft operation and its angle of swing is converted to electrical pulse, the PLC PLD is connected with rotating coder by high speed counting module, receive the rotary angle signal that detects, the PLC programmable logic device drives two safety type auxiliary reclays, two safety type auxiliary reclay difference solenoidoperated cluthes duplex solenoid valves, the contact series connection of two safety type auxiliary reclays outputs signal to the PLC PLD, thereby as can be known this moment two safe auxiliary reclays working state, form redundant self check loop; Described man-machine interaction interface is connected with the PLC PLD, reflects the working state of clutch in real time.
In conjunction with Fig. 2, the controlling method of a kind of clutch redundancy control device of the present utility model may further comprise the steps:
Step 1, PLC PLD carry out self check, and execution in step 2 after self check was finished, otherwise proceed self check;
Step 2, PLC PLD receive extraneous instruction and open clutch, and this moment, two safety type auxiliary reclays were started working;
The contact series connection of step 3, two safety type auxiliary reclays outputs signal to the PLC PLD, thereby as can be known this moment two safe auxiliary reclays working state, form redundant self check loop, to judge the state of two Security auxiliary reclays, if state is execution in step 4 then well, otherwise on man-machine interaction interface display alarm information;
Step 4, clutch drive bent axle, thereby make the encoder that is connected with bent axle send electrical pulsing signal to the PLC programmable logic device, the PLC programmable logic device is judged the encoder working state, thereby whether clutch operating is correct as can be known, if correct execution in step 5 then, otherwise on man-machine interaction interface display alarm information;
Step 5, PLC PLD receive extraneous instruction and close clutch, this moment, two safety type auxiliary reclays quit work, the contact series connection of two safety type auxiliary reclays outputs signal to the PLC PLD, thereby as can be known this moment two safe auxiliary reclays working state, if working state correctly then returns step 2, otherwise on man-machine interaction interface display alarm information.
The utility model allows clutch duplex solenoid valve be in the Redundant Control state at existing clutch duplex electromagnetic valve above shortcomings, not only can and distinguish dangerous misoperation, can also demonstrate the fault point intuitively.
The redundancy control apparatus of a kind of clutch duplex solenoid valve of the present utility model, the PLC controller that comprises powder compacting machinery and configuration thereof, the rotating coder that is installed on the bent axle connects the PLC controller, it is characterized in that the output shaft on the described bent axle is connected with rotating coder by flexible coupling, rotating coder links to each other with the PLC controller by high speed counting module, shows that the touch screen display of duplex solenoid valve working state links to each other with the PLC controller by RS232C; The safety relay of control duplex solenoid valve is by the relay output control of PLC.
When the utility model is worked by carry out the dual valve solenoid valve when needs, two output points of PLC drive two safety relaies that are attached thereto simultaneously, two safety relaies drive the duplex solenoid valve respectively, simultaneously a group leader of two safety relaies is opened the input point that signal that the contact is together in series inputs to PLC, working state with definite two safety relaies is normal, otherwise then output alarm information is to touch screen display, with the prompting maintenance man.Simultaneously, after the work of duplex solenoid valve, clutch couples together driving link flywheel and driven member driving mechanism, is installed on the rotating coder on the bent axle this moment, will send pulse give the high speed counting module of PLC, therefore can determine duplex solenoid valve this moment proper functioning.Otherwise, illustrate that then the duplex solenoid valve breaks down, PLC is the positive closing output point, simultaneously on touch screen display with output alarm information, with the prompting maintenance man.
