Embodiment 1
As shown in Figure 1: the described single-phase electricity load of the present embodiment remote auto is controlled supply unit by the complete machine working power circuit, remote activation instruction identification circuit, and power supply, outage are carried out control circuit and are formed by holding the continuous recognition control circuit of powering.The described outside line of the present embodiment (dc impedance) refers to the power control switch front end to the loop wire circuit between the load terminal, and power control switch refers to plug-in strip.
Described complete machine working power circuit is made of K switch, transformer B, rectifier bridge stack Q1, filter capacitor C1, three-terminal voltage-stabilizing circuit WY.The course of work is: AC power is delivered to the elementary of transformation B1 device through K switch, behind transformer pressure-reducing, send into bridge heap Q1 and carry out rectification, obtain pulsed dc voltage, enter three terminal regulator WY after filter capacitor C1 filtering, the 220V direct voltage of last stable output provides the energy for the work of complete machine.
Described remote activation instruction identification circuit is by diode D3, adjustable resistance RW2, and resistance R 2, R3, R4, R5, triode T1 forms.The remote activation principle is to adopt dc impedance to be serially connected in the triode T1 base loop, controls the operating state of T1, reaches the purpose of identification.As outside line N, when L does not have the load enabled instruction, the base stage of three utmost point T1 pipes does not have operating voltage, so T1 is cut-off state, its collector electrode output high level, resistance R 5, diode R4, high level after resistance R 6 dividing potential drops, IC1 is failure to actuate, the not adhesive of J1 relay, outside line is out-put supply not, when outer linear load enabled instruction sends, operating voltage is through R3, the outer linear load of RW2 starts impedance R2, R3, the T1 base stage, T1 gets electric work, becomes the conducting saturation condition by cut-off state, and its utmost point electrode output becomes low level from former front high level, make IC1 work, J1 adhesive out-put supply, simultaneously its contact J1-3, the load command loop has been cut off in J4-6 conversion, but instruction has transmitted and finishes.
Described power supply, outage are carried out control circuit by the IC1 integrated circuit, capacitor C 3, C4, and resistance R 6, R7, diode D6, D7, relay J 1 consists of.The course of work is: when outside line did not have the electricity consumption instruction to transmit, 2 pin of IC1 were high level, and the at this moment tripod of IC1 output is low level, and relay J 1 can adhesive, and its contact can not changed, and outside line does not just have power supply output.When outer linear load electricity consumption instruction transmitted, 2 pin of IC1 sported electronegative potential from high potential, cause that 3 pin of IC1 are high potential from the electronegative potential saltus step, and relay J 1 gets electric adhesive, its contact J1-3, J4-6 conversion, and power supply is just confessed to outside line.Obviously the J1 contact disconnects T1 work loop, 2 pin of IC1 are got back to high potential, but because the IC1 circuit is the monostable form, its 3 pin is still exported high level and trigger, (time can be regulated definite, the present embodiment is about 20 seconds) within this time, plug-in strip is to the outside line out-put supply, delay time just becomes low level from the output high level to 3 pin of IC1, if changing the high potential of road maintenance, relay J 1 will not discharge, its contact disconnects, and cuts off the power supply of outside line, thereby finishes power supply, outage execution purpose.
Described holding continues the power supply recognition control circuit by Current Mutual Inductance coil B2, diode D2, and capacitor C 2, pressurizer DW, adjustable resistance RW1, fixed resistance R8, triode T2 and diode D5 consist of.Adopt the alternating current impression principle whether to reach identification loaded work piece state, thus the execution of control continued power or disconnection.The course of work is: in the outside line power-on time, if the actual not work of load, just not having electric current among the outside line current transformer B2 passes through, secondly the utmost point just can not produce the alternation induced current, and triode T2 can not get corresponding induced voltage and ends, after 3 pin of IC1 become low level, relay J 1 will dead electricity and is discharged, its contact has disconnected the out-put supply of outside line, has realized the function of " during not electricity consumption of load, plug-in strip is outage just ".If in outside line power supply time-delay process, load brings into operation, just there is like this load current to flow through among the Current Mutual Inductance coil B2, according to the alternating current impression principle, B2 the utmost point certainly leads to the alternating current of induction, through diode D2 halfwave rectifier, just produced level and smooth direct voltage after capacitor C 2 filtering, (this direct voltage is that the induction of loaded work piece electric current produces, it has truly reflected the operating state of load) this voltage makes triode T2 become the conducting saturation condition from cut-off state, the power supply positive potential passes through T2, D5 has guaranteed the lasting adhesive of relay J 1 to relay J 1, exactly after the 3 pin output of IC1 becomes low level, relay J 1 has been changed rood and has been arrived high level and kept adhesive, reach the function of " load electricity consumption, plug-in strip is with regard to automatic power ", if during the load electricity consumption, the outside line broken string, load just quits work, and B2 does not just have induced current to produce, and T2 just can conducting, J1 discharges with regard to not having electricity, its contact just disconnects, and also with regard to auto-breaking, reaches the purpose of safe transmission.
The operation principle of the present embodiment is:
When 1, static.At this moment, complete machine is in electroless state, and itself does not consume electric energy yet.Outer linear load move instruction also is failure to actuate.
2, dynamically the time.At first closed knife switch K, complete machine has been served working power, is in holding state.Outside line is out-put supply not, also can dangerously not occur even people touch outside line, has good fail safe.
When the load electricity consumption, namely started the electricity consumption instruction, this instruction is sent to the output N of plug-in strip through outside line, L, direct-current working volts are through diode D3, adjustable resistance RW2, the primary coil B2 of the 6-5 pin of relay J 1, the 2-3 pin of load command dc impedance N.J1, resistance R 3, the T1 of base stage, T1 becomes this conducting saturation condition from former front cut-off state, the collector electrode of T1, P point current potential becomes this low level from high level, after 2 pin of IC1 receive this low level, the inner upset, 3 pin of IC1 just become high level from low level, this high level is delivered to 1 pin of relay J 1 through diode D6, relay J 1 gets electric just action, the 2-1 of its contact J1 and the 5-4 adhesive of J1, power supply just exports outside line to by this two windings point, finished the function of " Long-distance Control power supply ", the LED luminous tube is bright, illustrates that outside line has begun power supply, at this moment the operating state of IC1 is monostable definite form, the high level of the 3 pin output of IC1 only has the time-delay (this time artificially arranges) about 20 seconds, and time-delay one is arrived, and 3 pin of IC1 still can become low level automatically.In this time-delay power-on time, load has been worked really, so, load current will inevitably produce the alternating current impression electric current in B2 (this induced current is exactly the reflection of loaded work piece state, recognition and verification is exactly according to this induced current), through the D2 rectification, obtain corresponding direct voltage after the C2 filtering, through RW1, R8 makes T2 become conducting from cut-off to triode T2, and direct-current working volts pass through T2, D5 delivers to 1 pin of J1 relay, the J1 relay obtains changing the high level on road, just can continue to keep attracting state, namely guarantee the output of exterior line power supply, after the IC1 time-delay is complete, 3 pin recover low level, keep voltage but J1 is existing, thereby reach the function of " during the load electricity consumption, plug-in strip is with regard to automatic continuous power supply ".If in the IC1 delay time, load is work not, and B2 does not just have the alternation induced current, and T2 also continues cut-off with regard to the direct voltage that can not get conducting.When IC1 has delayed time 3 pin output when becoming low level, relay J 1 will discharge, and its contact returns to static state, thereby has cut off the output of power supply.In like manner, if outside line is broken suddenly in power supply, be equivalent to load and do not work, according to the output of the same automatic cut-off power of above-mentioned principle.
Embodiment 2
As shown in Figure 2: the formation of the described three-phase electricity load of the present embodiment remote auto control supply unit and embodiment 1 described single-phase electricity load remote auto control supply unit is basic identical, also by the complete machine working power circuit, remote activation instruction identification circuit, power supply, outage are carried out control circuit and are formed by holding continuous power supply recognition control circuit.Described outside line also refers to the power control switch front end to the circuit between the load terminal, and power control switch refers to plug-in strip.Its difference mainly is: in the complete machine working power circuit, AC power is delivered to the elementary of transformation B1 device through K switch, behind transformer pressure-reducing, send into bridge heap Q1 and carry out rectification, obtain pulsed dc voltage, enter three terminal regulator WY after filter capacitor C1 filtering, the 380V direct voltage of last stable output provides the energy for the work of complete machine.
In power supply, outage execution control circuit, be provided with two switching relay J1, J2 and two triode T2, T3.Because the output of three-phase alternating current, general power is larger, must finish with larger relay, so increased a switching relay J2, the pick-up voltage of this relay is to exchange 380V's, drive the adhesive of relay J 1 with the contact of relay J 2, the purpose that reaches and function and embodiment 1 described single-phase electricity are in full accord.The purpose that increases by two triode T2, T3 is that solution three characteristics of the middle term electricity electric current is larger, the elementary principle of Current Mutual Inductance coil B2 can only be passed the induced magnetism stamen, the number of turns must reduce, and the electric current of sensing time utmost point also can be little, for reliable reflected load operating state, only has the one-level of increasing amplifying element, just can guarantee the T2 in the T4(single-phase electricity) the triode conducting, reliable high level is provided for the J2 relay, the adhesive when keeping changing the road, thereby realize the function of " electricity consumption of carrying being arranged, the plug-in strip automatic power ".
