Below in conjunction with drawings and Examples, the utility model is described in further detail.Be understandable that, specific embodiment described herein only for explaining the utility model, but not to restriction of the present utility model.It also should be noted that, for convenience of description, the part relevant to the utility model is illustrate only but not full content in accompanying drawing, unless otherwise defined, all technology used herein and scientific terminology are identical with belonging to the implication that those skilled in the art of the present utility model understand usually.Term used herein, just in order to describe specific embodiment, is not intended to be restriction the utility model.
Please refer to shown in Fig. 1, the electric cam stop structural drawing that Fig. 1 provides for the utility model embodiment.
In the present embodiment, electric cam stop specifically comprises stop body 101, button group 102, pulse-detecting circuit 103, micro-control circuit, digital pipe display circuit, power circuit and communication module group.The follower gear of described stop body 101 middle gear group is provided with grating disk, and this grating disk is provided with weekly printing opacity lattice, detects pulse signal weekly by pulse-detecting circuit 103.Described button group 102 connects micro-control circuit.The output terminal of described pulse-detecting circuit 103 connects the input end of micro-control circuit.The input end of described digital pipe display circuit connects the output terminal of micro-control circuit.Described power circuit connects micro-control circuit and digital pipe display circuit.Described communication module group is connected with micro-control circuit.Described micro-control circuit comprises micro-control unit 104 and storer 105, and storer 105 connects micro-control unit 104, and single-chip microcomputer connects button group 102.Described digital pipe display circuit comprises interconnective first charactron 106, first latch 107, second charactron 108 and the second latch 109.Described power circuit comprises power management module 1010 and battery 1011, and power management module 1010 connects micro-control unit 104, first charactron 106, second charactron 108, and battery 1011 connects power management module 1010.Described communication module group includes but not limited to RS485 module 1012 and CAN module 1013.In the present embodiment, described power circuit also comprises charging inlet 1014; Chargeable lithium cell 1011 selected by described battery 1011.Described micro-control unit 104 selects STM32F10X series monolithic.Described button group 102 comprises two metal switches, when arranging mode of operation, presses 2 metal switches simultaneously, when interface can become " Eoc-0000 ", metal switch position+1, another-1, be set to digit pulse, long can accelerate to add up by switch.
Electric cam stop arranges required pulse value by button group in the present embodiment, by the photoelectricity measuring and calculating pulse transducer detection of gear pulse of pulse-detecting circuit, export to the micro-control unit of micro-control circuit, micro-control unit judges the downstream pulses of current motor and whether arrange pulse equal, if equal, then send instruction pilot relay and quit work.If if do not receive any motor downstream pulses in startup certain hour, then single-chip microcomputer output alarm signal is to digital pipe display circuit, numeral method " ERROR " also continues flicker, and reminding user illustrates that fault exists.It should be noted that, cam stop is when initial point, and numeral method 000, shows umber of pulse time descending, and put in place flickering display umber of pulse when stopping, malfunction coefficient ERR.For two-way fault-signal: one, umber of pulse stops not cumulative (walking stops), by controlling the normally opened contact action of auxiliary reclay 1, connects fault-signal.Two, dead electricity is out of control: controlled by the normally closed contact of auxiliary reclay 2.Dead electricity is that normally closed contact connects fault-signal, has the normal operation contact of electricity to disconnect.Above two contact shunt realize failure alarm signal.The utility model specific works process is as follows: after one, switching on power, charactron (first digital, the second charactron) interface display " Noc-0000 ", this is main interface, now, if photoelectricity measuring and calculating pulse transducer has gear pulse to enter, then can add 1, as being shown as " Noc-0001 ".Two, arrange under mode of operation to digit pulse: press 2 metal switches simultaneously, when interface becomes " Eoc-0000 ", metal switch position+1, another-1, be set to digit pulse, long by accelerating to add up.For grab bucket, do not know if current will arrange the dive of how many pulse ability to water-bed, so directly open PLC motor and carry out descending, if photoelectricity measuring and calculating pulse transducer senses that motor rotates the current setting pulse that also can add up.When after setting completed, press two metal switches to preserve current pulse simultaneously, turn back to main interface and be namely shown as " Noc-0000 ".Wherein, the downstream pulses of current setting re-powers in second time and can be saved and can't lose.Three, run: after setting up pulse value, namely start to start by next metal switch arbitrarily, interface display is " Run-0000 ".Now, the downstream pulses of single-chip microcomputer record current motor, when equal with arranging pulse value, pilot relay exports stop signal.If do not receive any motor downstream pulses, then output alarm signal in 10s after starting, numeral method " ERROR " glimmers, and reminding user fault exists.After fixing a breakdown, only need to eliminate fault mode by next metal switch arbitrarily.
