Abstract
The invention relates to a switch type intelligent controller which consists of three parts which are respectively a power supply part, a control signal delay part and a current control signal amplification part; an alternating voltage signal of the power supply part is commutated and filtered by filter capacitors C6 and C7, then stabilized by a stabilivolt DW2 to obtain a stabilized voltage as a power voltage of the intelligent controller; a current control signal of the control signal delay part samples through a sampling current transformator L, is stabilized by a stabilivolt DW1 and filtered by filter capacitors C1and C2 in order to conduct an audion BG1 and charge a delay capacitor C4; when the current control signal is interrupted or interfered, the delay capacitor C4 discharges so as to have anti-jamming function; an audion BG2 of the current control signal amplification part is conducted to amplify the current control signal and drive a relay J to operate. Through processing the control signal, the switch type intelligent controller can modify the current for driving the operation of the relay, achieve the universality of application and at the same time ensure the anti-jamming function due to the induction of the delay capacitor.
Description
Technical field
The present invention is a kind of controller, particularly a kind of switch type intelligent controller.
Background technology
More existing controllers often are confined to a narrow range of application, and its extensibility is not high, and are subjected to interference ratio bigger when control signal, can make the machine works instability need add artificial control sometimes, just can make the machine operate as normal.
Summary of the invention
The objective of the invention is in order to overcome traditional controller range of application not widely, and be subjected to the bigger shortcoming of interference effect, invent and a kind ofly can be applicable to many field of electronics, as electric welding machine, refrigerator, television set, the switch type intelligent controller of printer or the like.
The objective of the invention is to realize as follows: described switch type intelligent controller has three parts: one is the power supply part, ac voltage signal is through the rectification of voltage bridge rectifier U, by two filter capacitor C6, the filtering of C7, obtain voltage signal more stably, after this signal passes through the voltage stabilizing of voltage-stabiliser tube DW2 again, obtain the supply voltage of stable voltage as this intelligent controller, current-limiting resistance R8 can play the excessive effect of restriction electric current; Two are control signal time-delay part, current controling signal is taken into this intelligent controller by the sampling of sampled current transformer L, diode D1, D2 has guaranteed the unidirectional conduction of electric current, but the voltage stabilizing stabling current control signal of voltage-stabiliser tube DW1, again by filter capacitor C1, the filtering of C2, with control base resistance R7, RW, R1, the current limliting of R2 and current-limiting resistance R3, make triode BG1 conducting, obtain high level signal, and delay capacitor C4 is charged by not gate, when interrupting appears in current controling signal or be interfered greatly, since the introducing of this delay capacitor C4, and had corresponding discharge time, possessed good anti-interference function thus; Three is the current controling signal amplifier section; current signal passes through not gate; make triode BG2 conducting; this moment, triode BG2 was operated in the signal magnifying state, and current controling signal is amplified, and made current controling signal can drive the relay J action; diode D4 has played the afterflow effect; resistance R 5, R6 is a current-limiting resistance, restriction electric current and protective circuit.
Good effect of the present invention is as follows: this switch type intelligent controller, by processing to current controling signal, can guarantee at electric current during as required greater than a certain value, relay normally open point is closed, can make peripheral electrical and electronic circuit be operated in normal condition, less when electric current, relay disconnects, and reaches the peripheral circuit power down function; Perhaps conversely when electric current during less than a certain value, relay closes, peripheral circuit operate as normal; when electric current excessive; relay disconnects and reaches the function of protecting peripheral circuit, and this has embodied the popularity that this intelligent controller is used, and the introducing of delay capacitor has simultaneously also guaranteed jamproof function.
