Self-powered breakage stopping device for frame-type strander
Technical field
The present invention arranges a kind of cable manufacture field, specifically refers to a kind of self-powered breakage stopping device for frame-type strander.
Background technology
The frame winch is that cable manufacturer is at the indispensable production equipment of producing twisted wire.Electric wire is in the middle of the frame winch carries out the twisted wire process, because discharging appears in every dish electric wire (aluminum steel, or copper cash) or the strand tensile process reason such as fracture occurs and makes and need parking, with a large amount of precious metals and the manpower of having avoided waste.But domestic old-fashioned frame winch generally lacks the outage parking function at present, therefore needs to be equipped with the running that a large amount of manpowers removes to monitor these frame winches, and the recruitment cost is high, and intelligent degree is poor.Therefore, the at present domestic frame winch intelligence line-breaking stoppage control device that also occurred, but install existing old-fashioned frame winch additional the line-breaking stoppage control device, must the teardown of engine, and in frame winch draw drum, install conducting slip ring additional, and the working power of transducer and other control apparatus delivered to frame winch draw drum the inside, because the bulky dismounting difficulty of frame winch makes a lot of producers can't realize that right old-fashioned frame winch installs the line-breaking stoppage function additional.
Summary of the invention
The objective of the invention is the shortcoming and defect that exists in order to overcome prior art, and a kind of any mechanical structure that need not change the frame winch is provided, can realize the self-powered breakage stopping device for frame-type strander of line-breaking stoppage function.
For achieving the above object, technical scheme of the present invention is a plurality of transducers, signal processing module, wireless transmission slave, wireless receiving main frame and self powered supply, wherein:
The quantity of transducer is corresponding with the draw drum quantity of frame winch, and whether transducer rotates for detection of each draw drum, and according to draw drum rotation status output pulse signal;
The quantity of signal processing circuit is corresponding with number of sensors, and signal processing circuit is used for converting the output pulse signal of transducer to temporary stable state high level;
The wireless transmission slave includes PNP triode and wireless transmitter module, and wherein the signal output part of each signal processing circuit all is parallel to the B utmost point of PNP triode, and the C utmost point of this PNP triode is connected with wireless transmitter module;
The wireless receiving main frame comprises wireless receiving module, is used for receiving wireless transmission slave signal, and output alarm and parking control signal;
Self powered supply and transducer, signal processing module and wireless transmission slave are installed in the draw drum together, are transducer, signal processing module and the power supply of wireless transmission slave.
Further arranging is that described self powered supply includes direct current tachogenerator, charging circuit and storage battery, and described direct current tachogenerator is driven to be installed on the draw drum rotating shaft.
Further arrange is that described signal processing circuit is the MIC1555 single-chip microcomputer that is integrated in the transducer.
Further arranging is that described transducer is the low-power consumption Hall element.
Further arrange be described signal processing circuit output be the temporary stable state high level of pulsewidth 3S.Storage battery is pure excide battery.
Advantage of the present invention is, utilize the frame winch when the twisted wire operation, twisted wire drives the draw drum rotation, and this direct current tachogenerator is subjected to draw drum to drive generating, and charge a battery by charging circuit, thereby be transducer, signal processing module and the power supply of wireless transmission slave, therefore take the frame winch apart compared to existing needs and install conducting slip ring additional and carry out supply power mode, the present invention need not change any mechanical structure of frame winch, and repacking is simple.
Below in conjunction with specification drawings and specific embodiments the present invention is done further introduction.

Embodiment
Below by embodiment the present invention is carried out concrete description; only be used for the present invention is further specified; can not be interpreted as the restriction to protection range of the present invention, the technician in this field can make some nonessential improvement and adjustment to the present invention according to the content of foregoing invention.
The specific embodiment of the present invention shown in Fig. 1-4, a plurality of transducers, signal processing module, wireless transmission slave, wireless receiving main frame and self powered supply, wherein:
The quantity of transducer is corresponding with the draw drum quantity of frame winch, and present embodiment arranges 30 groups of transducers, and whether transducer rotates for detection of each draw drum, and according to draw drum rotation status output pulse signal; The quantity of signal processing circuit is corresponding with number of sensors, and signal processing circuit is used for the output pulse signal of transducer is converted to the temporary stable state high level of pulsewidth 3S; The present embodiment signal processing circuit is the MIC1555 single-chip microcomputer that is integrated in the transducer, and transducer is the low-power consumption Hall element, can guarantee the service time of self powered supply.
Present embodiment wireless transmission slave includes PNP triode and wireless transmitter module, and wherein the output of the signal of each signal processing circuit all is parallel to the B utmost point of PNP triode, and the C utmost point of this PNP triode is connected with wireless transmitter module.
Above-mentioned MIC1555 single-chip microcomputer plays temporary stable state effect, a plurality of Hall elements are when draw drum rotates, provide simultaneously a delay pulse, MIC1555 begins the temporary stable state high level of output pulse width 3S, has guaranteed that the PNP triode B utmost point keeps high level, C does not export, in case any one Hall element causes draw drum to stop operating because broken string or cable such as discharge at the state, and does not have output pulse signal, the MIC1555 output low level, the conducting of PNP triode, wireless transmitter module transmits.
The wireless receiving main frame comprises wireless receiving module, is used for receiving wireless transmission slave signal, and output alarm and parking control signal.
Self powered supply and transducer, signal processing module and wireless transmission slave are installed in the draw drum together, are transducer, signal processing module and the power supply of wireless transmission slave.The described self powered supply of present embodiment includes direct current tachogenerator, charging circuit and storage battery, and described direct current tachogenerator is driven to be installed on the draw drum rotating shaft.
The course of work of the present invention is whether operation principle is will detect cable to break or discharge, we at first will go to detect by transducer, whether every dish line has rotation, every dish line that works can drive the draw drum rotation in the twisted wire process, transducer detects the pulse that the draw drum rotation produces, be input to the sensor internal integrated circuit, integrated circuit whenever receives 3 seconds temporary stable state high level of 1 pulse 1 pulsewidth of output, triggering is from the input of controller, if there is not the pulse input after 3 second time, be broken string from controller is inner disconnected, send to the wireless receiving main frame of frame winch outside by wireless module, main frame output relay controller chassis winch stops and reports to the police.
