As a specific embodiment, one piece of LM393 dual comparators integrated circuit is selected to compare as two voltages
Device U1, U2；Its six diodes select 1N4004 rectifier diodes；Capacitance C0 selects the capacitance of 0.01 μ F/630V；Capacitance C3
Select the capacitance of 0.47 μ F/400V；Capacitance C selects 0.10 μ F/63V；Capacitance C2 selects 0.47 μ F/63V；Capacitance C1 selects 1000
μF/35V；Resistance R1, R2, R3, R4, R5, R8, R9, R10 select 5.1k Ω, 1M Ω, 51k Ω, 51k Ω, 1M Ω, 300 respectively

Silicon photoelectrical coupler MOC selects MOC4060；Bidirectional trigger diode DB selects DB3；Silicon-controlled BT selects common unidirectional controllable
Silicon.In addition, after the alternating voltage of J4 interfaces access 220V/50Hz, by capacitance C1, C3, resistance R5, rectifier diode D1, D2,
After the controlling power circuit that D3, D4 and zener diode DW are formed, the control DC voltage of nearly 10V (± 5V) can be obtained, is met
The power reguirements of this control device and external sensor (conventional sensors operating voltage is 5-36V).
The circuit two of control device
As shown in figure 3, the circuit and circuit shown in Fig. 2 difference lies in：Single-phase rectifier is become by full-controlled rectifier, because of list
The electric current of commutating phase output only has the half of full-controlled rectifier, and therefore, corresponding C3 capacitances are increased to by 0.47 μ F in Fig. 2
1μF；Start-up and shut-down control module becomes single comparator by dual comparator, and corresponding control circuit makes an adjustment.
It is specific different as follows：
Control power supply is made of resistance R5, capacitance C1, capacitance C3, zener diode DW, diode D1 and diode D2；Two
Pole pipe D1 and D2 form a single phase half wave rectification bridge, the positive and negative anodes of the DC terminal of rectifier bridge power supply in order to control, the fire of alternating current
Line is by the tie point of capacitance C3 connection diodes D1 and D2, and capacitance C3 is in parallel with resistance R5, capacitance C1 and zener diode DW
Connection control power supply after parallel connection.Under the collective effect of capacitance C1 and zener diode DW, DC voltage is made to maintain voltage stabilizing two
In the voltage stabilizing value of pole pipe DW.
Start-up and shut-down control module further includes resistance R1, resistance R2, diode D5, resistance in addition to comparator U1 and capacitance C2
Control power supply, the signal output part connection resistance of sensor are connected after R3 and resistance R4, resistance R1, resistance R2 and capacitance C2 series connection
The tie point of R1 and resistance R2, resistance R2 are connected the inverting input of comparator U1, resistance R3 and electricity with the tie point of capacitance C2
Connection controls power supply after hindering R4 series connection, and resistance R3 connects the in-phase input end of comparator U1, resistance R2 with the tie point of resistance R4
It is positive in parallel with diode D5.The program compared with upper scheme, the difference is that：When material is not detected, pass through two poles
Pipe D5 charges rapidly to capacitance C2；And when detecting material, because diode D5 reversely ends, capacitance C2 can only be slow by R2
Electric discharge；Because comparator U1 input sides wiring with upper scheme on the contrary, after opposite twice, the output effect of comparator U1 and top
Case is identical.
To the eye, which saves a comparator, saves a diode, but because of the comparison of one, market
The integrated circuit of device is suitable with the IC cost of two comparators, and the price of LM393 dual comparators only has unitary or so,
Which still selects LM393, therefore, does not save the cost of integrated circuit.Meanwhile because the capacity of capacitance C3 increases, instead
Add cost.
The circuit three of control device
As shown in figure 4, circuit structure in the circuit structure and Fig. 2 difference lies in：AC power passes through a transformation
Device is connected to rectifier bridge, so electric current becomes transformer pressure-reducing formula from capacitor step-down；Silicon-controlled BT is from unidirectionally becoming two-way.
It is specific different as follows：
Power supply is controlled by step-down transformer B2, capacitance C1, diode D1, diode D2, diode D3 and diode D4 structures
Into；Diode D1, diode D2, diode D3 and diode D4 form a fullwave rectification bridge, the DC terminal of rectifier bridge
The positive and negative anodes of power supply in order to control, alternating current pass through the exchange side of step-down transformer B2 rectifier bridges, capacitance C1 connections control power supply.Drop
No matter cost, volume and the equal specific capacitance of loss are depressured height to pressure transformer, and therefore, this programme cost will suitably improve.But because of control
It is not electrically connected between circuit and external sensor and AC power, it is therefore, more safer than scheme 1 and scheme 2.
Silicon-controlled BT is from unidirectionally becoming two-way, is only exactly ability in AC supply voltage because single-phase tactile punching forms circuit
Formed trigger pulse, therefore, no matter it is silicon-controlled be it is unidirectional or two-way, control effect is identical.
The circuit specifically controls process identical with the control process of the circuit in Fig. 2, does not repeat here.
