Abstract
The utility model discloses a time circulating controlling apparatus which belongs to the technical field of electron, and is composed of a relay, a time control circuit, a rectifying and filtering circuit and a signal amplifying circuit, wherein a coil of the relay is connected with the signal amplifying circuit in series, and the input end and the output end of the time circulating controlling apparatus are connected by a normally-opened contact of the relay in series. The utility model has the characteristics of reasonable structure, little power consumption and high reliability, and can control all electric appliances needing to be turned on and off through timing, such as street lamps, neon lamps, lamps of advertisement signboards, production apparatuses, etc., so as to realize permanent circulating control.
Description
The utility model belongs to electronic technology field, relates to a kind of opening-closing timing control device.
The timer of people's use at present can not circulate and control automatically.When the needs loop control, can only adopt manual operation, very trouble.The all electronic timer that Chinese patent 90107026 provides is a kind of technical scheme that proposes at this problem.It mainly is made up of the cycle tunable oscillator, increases feedback compatible portion and switch, realizes electrical appliance is carried out multiple time control.But this timer construction is complicated, and power consumption is big and reliability is low, is difficult to be widely adopted.
The purpose of this utility model is exactly at the problems referred to above, provides a kind of simple in structure, safe and reliable and time loop control instrument that power consumption is little.
For achieving the above object, the time loop control instrument that the utility model provides is made up of relay, time control circuit, current rectifying and wave filtering circuit and signal amplification circuit, wherein relay coil is connected on the signal amplification circuit, and relay normally open contact is serially connected between the input and output of controller.This controller is to utilize the action of relay to realize the opening and closing of controlling object.And time control circuit, current rectifying and wave filtering circuit and signal amplification circuit are formed together, the action of control relay.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the electrical schematic diagram of time loop control instrument provided by the utility model.
As shown in the figure, the time control circuit of this time loop control instrument comprises ic chip 4011 and potentiometer R1, R2 and resistance R 3, R4, capacitor C 2, C3.Potentiometer R1 is used for controlling the length that booth ends the time; Potentiometer R2 is used for controlling the length of running time.In addition, resistance R 5, R10, R11 play the dividing potential drop effect.
The current rectifying and wave filtering circuit of this time loop control instrument is made up of diode D1, D2, capacitor C 1 and resistance R 6.The input I of this controller generally is connected on the AC power of 220V, behind current rectifying and wave filtering circuit, becomes the operating voltage of time chamber system circuit, signal amplification circuit etc.
The signal amplification circuit of this time loop control instrument comprises triode Q1 and Q2, resistance R 7, R8.It is that the signal that time control circuit is produced amplifies, then the relay coil J by connecting with it.In the present embodiment, resistance R 9 is a divider resistance, and diode D3 is a light-emitting diode.The normally opened contact K of relay is serially connected between input I and the output O.
During this time of use loop control instrument, at first regulator potentiometer R1 and R2 select required dwell time and running time; Connect with the mains at its input I then, the voltage of input I behind current rectifying and wave filtering circuit, time control circuit and signal amplification circuit, makes the actuating of relay successively, thereby the normally opened contact K of control relay realizes the timing of controlling object is opened and closed.
Compared with prior art, this time circulation controlling apparatus have rational in infrastructure, power consumption is little, reliability is high Characteristics, all need to regularly be opened and close can to control street lamp, neon light, advertising signboard lamp, production equipment etc. The electric equipment that closes is realized permanent loop control.
