Referring to Fig. 4, the reset circuit includes the 7th resistance R7, the 8th resistance R8, the 9th resistance R9, the tenth resistance R10, eleventh resistor R11, twelfth resistor R12, thirteenth resistor R13, the 14th resistance R14, the 15th resistance R15, 16 resistance R16, the 7th capacitor C7, the second diode D2, third diode D3, the first triode Q1, the second triode Q2, Three triode Q3, optocoupler U3 and second interface J2, the optocoupler U3 use PC3117.4 feet of the second interface J2 One end of the 7th resistance R7 is connected, the other end of the 7th resistance R7 is connect with 1 foot of one end of the 9th resistance R9 and optocoupler U3, 2 feet of optocoupler U3 connect the other end of the 9th resistance R9 and one end of the 8th resistance R8, the other end of the 8th resistance R8 and the 5 feet of two interface J2 connect, the base stage and the tenth of the anode of 3 feet of optocoupler U3 and the second diode D2, the first triode Q1 One end of resistance R10 connects, and the collector of the first triode Q1 connects the cathode and eleventh resistor R11 of the 7th capacitor C7 One end, anode and the anode of third diode D3, the base stage and twelfth resistor R12 of the second triode Q2 of the 7th capacitor C7 One end connection, one end of the collector of the second triode Q2 and one end of thirteenth resistor R13 and the 14th capacitor R14 connect It connects, the other end of the 14th resistance R14 is connect with the base stage of one end of the 15th resistance R15 and third transistor Q3, third The collector of triode Q3 is connect with one end of the 16th resistance R16, and is commonly connected to the reduction voltage loop, and described the 4 feet of two interface J2 and 5 feet connect machinery equipment, for receiving reset signal, as long as having received level between 4 feet and 5 feet Variation finally gives one electricity of reduction voltage loop after then converting by the first triode Q1, the second triode Q2, third transistor Q3 Ordinary mail number makes reduction voltage loop stop working, and plays the role of to yarn rider and measure loop power-off restoration.The 2 of second interface J2 Foot provides signal for connecting machinery equipment, to machinery equipment.

Referring to Fig. 5, the measure loop includes the 17th resistance R17, the 18th resistance R18, the 19th resistance R19, the second Light-emitting diode LED 2, the 4th diode D4, the 4th triode Q4, controller MCU and disconnected through detection switch JP, Wherein, the MCU is preferably the MCU of SOT23-6 encapsulation.The output loop includes the 20th resistance R20, the 21st Resistance R21, the 22nd resistance R22 and the 5th diode D5.The input terminal and the 17th resistance of the controller MCU One end of R17 connects, and commonly through disconnected through detection switch JP connection yarn rider.Described breaking through detection switch JP includes existing Yarn rider chip, iron clad and menopause tablet described in technology, when warp break, menopause tablet due to losing the tube bank of warp thread from Vacant state becomes falling state, and chip is connected with iron clad at this time, i.e., disconnected to be closed through detection switch JP.When disconnected through detection switch JP When closure, the branch where the second Light-emitting diode LED 2 is connected, and the second Light-emitting diode LED 2 is lighted, and operator is prompted to have Break through occurring.At this point, MCU exports a high level after input terminal receives low level, in output end, the 18th resistance is acted on The both ends of R18, the 18th resistance R18 provide a high level to the base stage of the 4th triode Q4, and the 4th triode Q4 is connected, the Signal on the collector of four triode Q4 is pulled low into low-potential signal and passes to machinery equipment after maintaining several seconds, by machine Equipment executes shutdown action and alarms, and waits operator to handle abnormal.In practical application, the collection of the 4th triode Q4 at this time Detection signal on electrode is to pass to machinery equipment by 2 feet of second interface J2.After the completion of abnormality processing, break through examining It surveys switch JP to disconnect, the power-off of 2 place branch of the second Light-emitting diode LED, the second Light-emitting diode LED 2 is extinguished, at this point, MCU is defeated The signal for entering end becomes high level by low level, and the output signal of output end then becomes low level from high level, while MCU is defeated The level for entering end carries out the low and high level switching at having time interval, and the second Light-emitting diode LED 2 is made to be connected to DC power supply VCC, Conducting, the cut-off switching of intermittent are done, and then makes the second Light-emitting diode LED 2 that the flashing being spaced be presented.In said structure, Once obtaining disconnected through signal, then the second Light-emitting diode LED 2 can be lighted at once, in the pre-structure that can be avoided because of menopause tablet Poor contact and the problem of cause indicator light not work；Further, it is also possible to distinguished to disconnected through state, there is a situation where resolve through Under, if disconnected signal stabilization, the second Light-emitting diode LED 2 after are always on, if disconnected through signal interruption, the second light emitting diode LED2 flashing.The output loop is exported to machinery equipment with being used to will test the signal stabilization that circuit detects.

Referring to Fig. 6, the measure loop further includes the 6th diode D6 and the 7th diode D7, the 6th diode D6 It is connected on described break through between detection switch JP and controller MCU, the cathode connection of the 6th diode D6 is disconnected through detection switch The cathode of JP and the 7th diode D7, the input terminal and the 17th resistance of the anode connection controller MCU of the 6th diode D6 One end of R17, anode and the collector of the 4th triode Q4, one end of the 20th resistance R20, the 20th of the 7th diode D7 The anode connection of one end of one resistance R21, one end of the 22nd resistance R22 and the 5th diode D5.It is opened when disconnected through detection It closes JP and detects that closure when warp thread disconnects, the second Light-emitting diode LED 2 are lit, prompt spinner to have disconnected through occurring.At this point, Original high level is become low level by the 7th diode D7 by signal on the 4th triode Q4 collector, while MCU After input terminal detects that level becomes low level by the 6th diode D6, a high level is exported in output end, acts on the The both ends of 18 resistance R18, the 18th resistance R18 provide a high level to the base stage of the 4th triode Q4, make the 4th triode It is grounded after Q4 conducting, the signal on collector is further dragged down into low-potential signal and passes to machine after maintaining several seconds and set It is standby, shutdown action is executed by machinery equipment and is alarmed, and waits operator to handle abnormal.After the completion of abnormality processing, break through examining Switch JP to be surveyed to disconnect, the signal on the 4th triode Q4 collector reverts to original high level by the 7th diode D7, the Two Light-emitting diode LED 2 are extinguished because place branch powers off.At this point, the signal of MCU input terminal becomes high level by low level, And the output signal of output end then becomes low level from high level, while the level of MCU input terminal carries out the height at having time interval Low level switching, makes the second Light-emitting diode LED 2 be connected to DC power supply VCC, does conducting, the cut-off switching of intermittent, in turn Make the second Light-emitting diode LED 2 that the flashing at interval be presented.
