Abstract
The invention relates to an automatic lever starter, namely an automatic startup circuit when a power supply is restored for an air conditioner. As shown in the figure, a monostable trigger driving circuit consists of an integrated circuit and a discrete transistor circuit. When the power supply is restored, the power supply charges a capacitor C to make the potential of a base on a transistor rise to quickly conduct the transistor; and when the capacitor C is fully charged, a voltage with a positive upper part and a negative lower part is formed at two ends of the capacitor C, so that the potential of the base of the transistor is reduced to cut off the transistor. By conducting and cutting off the transistor, a low triggering pulse is provided for NE555, a transient high pulse is output through an NE555 monostable circuit, a reed of a relay J is sucked through the driving circuit, and a metal lever is driven to control a remote control switch so as to trigger the air conditioner to automatically start up.
Description
Technical field
The present invention is a kind of automatic lever starter, the i.e. air-conditioning self-start circuit after restoring electricity, and belongs to electronics automatic
Control technology.The circuit is using integrated circuit and transistor discrete circuit composition monostable trigger drive circuit.In power up
After power supply, power supply charges to electric capacity C rises crystal triode base potential, and transistor turns, collector potential declines.Work as electricity
After container C electricity is full of, capacitor C two ends form just lower negative voltage on one makes transistor base potential decline make crystal then
Pipe ends.Using the conducting and cut-off of the transistor, there is provided give NE555 mono- low trigger pulse, by NE555 monostable circuits
One transient state high impulse of output, Jing Darlington drive circuits make relay J reed adhesives, drive bimetallic lever control remote control to open
Triggering air-conditioning restarting is closed, so as to reach the purpose of air-conditioning self-starting.After the of short duration time, monostable returns to stable state,
The active force release of bimetallic lever control remote control on ＆ off switch, lever self-starting process terminates.
Background technology
In torridity summer, such as：The places such as network computer room need air-conditioning the temperature remains within the normal range state.To ensure instrument and equipment just
Often operation.Once civil power power-off, then after restoring electricity, air-conditioning needs manually to start.Can make troubles to attendant or fiber crops
It is tired.In order to solve this problem, the present invention makes air-conditioning self-starting, it is to avoid power failure institute band using the automatic drive control circuit of incoming call
The trouble come.
The content of the invention
It is an object of the invention to design a kind of automatic lever starter, the i.e. air-conditioning self-start circuit after restoring electricity.
It is characterized in the bimetallic lever contact of automatic lever starter being pointed on (alignment) existing air-conditioning remote control on ＆ off switch, works as recovery
After power supply, an active force is switched to remote controller key by drives bimetallic lever, be allowed to open, air-conditioning is controlled then and is existed
Automatic after restoring electricity, there is good application and development prospect.
For achieving the above object, present invention employs following technical scheme：A kind of automatic lever starter, i.e. air-conditioning
The self-start circuit after restoring electricity.As shown in drawings.
Description of the drawings：Accompanying drawing is automatic lever starter circuit diagram.
The technical scheme is divided into three parts：
1. low level generative circuit
The circuit is mainly made up of electric capacity C and a crystal triode.Power up power after unidirectional current VCC to electric capacity C
Quick charge, rises crystal triode base potential, and transistor turns, collector potential declines.As capacitor C electricity is full of
Afterwards, capacitor C two ends form just lower negative voltage on one makes transistor base potential decline make transistor cutoff then.Utilize
The conducting and cut-off of the transistor, the input trigger of the low level pulse of generation as NE555 monostable circuits.
2. single-shot trigger circuit
" 2 " foot that undersuing is fed directly to NE555 integrated packages is produced by low level generative circuit, it is mono- by NE555
Steady-state circuit " 3 " foot exports a transient state high impulse.Transient state high-pulse widths=the 1.1RTCT of " 3 " foot output.Transient state time by
RT, CT decision, increases the pulse width, can make the on ＆ off switch of bimetallic lever contact reliable contacts remote control, it is ensured that remote control
Reliable triggering air-conditioning, is allowed to start.
3. Darlington lever actuated circuit
The transient state high impulse Jing Darlingtons driving tube exported by NE555 " 3 " foot drives, and signal amplifies, and obtains being enough to drive
Electric current needed for relay J coils, makes relay J reed adhesives bimetallic lever control the on ＆ off switch of air-conditioning remote control.Using thick stick
The fulcrum that rod principle passes through adjustment bimetallic lever, makes small reed suction obtain the pressure that be enough to drive air-conditioning remote control switch strong
Power, triggers starting of air conditioner.After the of short duration time, monostable returns to stable state, the release of remote control on ＆ off switch, lever self-starting
Journey terminates.
Claims (2)
1. a kind of automatic lever starter, the circuit of the automatic lever starter be powered using power up after to capacitor
C quick charges, rise crystal triode base potential, crystal triode conducting, after capacitor C electricity is full of, capacitor C two
End forms just lower negative voltage on one, and declining crystal triode base potential then ends crystal triode；Using this
The conducting and cut-off of crystal triode, there is provided give NE555 monostable circuits " 2 " foot one low trigger pulse, by NE555
Monostable circuit " 3 " foot exports a transient state high impulse, and Jing Darlington drive circuits make relay J reed adhesives, promote metal
