The explanation of circuit working principle:

Coded portion

RB0---RB5 is set to the data input port for these 6 mouthfuls, with exclusion RP1 (47K*8, only with 6) public power cathode and code switch (S101) " OFF " side of connecing, use 6 code switchs (S101) to receive on 6 mouths again, code switch " ON " side, run in and hinder RP2 (4.7K*8 is only with 6), common port is received positive source, like this, when code switch (S101) during in " OFF " side, sense data is " 0 ", when code switch (S101) during in " ON " side, because the effect of resistance, the current potential height, sense data is " 1 ", according to binary data, the position is set at " ON " or " OFF " and plays the coding effect accordingly, behind the microprocessor work, just coding is read in, and be deposited with low 6 in the register.

The button part

By the RA1 detection of manually progressively increasing, the RA1 mouth connects power cathode by R306 at ordinary times, make to detect data and be " 0 ", when pressing by key, electric current by power supply just, the R305 that flows through, button S1 makes the obvious noble potential of port, makes to detect data and be " 1 ".After microprocessor detects " 1 ", will carry out the program of progressively increasing accordingly.

By the RA2 detection of manually successively decreasing, the RA2 mouth connects power cathode by R308 at ordinary times, make to detect data and be " 0 ", when pressing by key, electric current by power supply just, the R307 that flows through, button S2 makes the obvious noble potential of port, makes to detect data and be " 1 ".After microprocessor detects " 1 ", will carry out the program of successively decreasing accordingly.

The interchange zero phase detects

RA3 detects and exchanges the zero phase signal, by resistance R 304, receives on the alternating current 220V line after the R305 series connection; Because employed microprocessor has the zero phase of interchange measuring ability, no longer need other peripheral components to finish measuring ability.

The work indication

By RB6 mouth output signal, through the R303 current limliting, flow through light emitting diode, connect power cathode, there is the noble potential light emitting diode just luminous, finish the indication task.

Working portion

By RB7 mouth output control signal,, enter optocoupler controllable silicon U1 through R301 protection current limliting; the ac high voltage side, from the control voltage that line of electric force is obtained, the step-down of process R309 current limliting; enter coupling mechanism; after the coupling, output to the bidirectional triode thyristor control utmost point again, control side electronegative potential; controllable silicon is obstructed; control side noble potential, the gauge tap task is finished in the controllable silicon conducting.When control side output be to be reference point to exchange zero phase, during the pulse signal of time-delay back output, according to the time-delay situation, the control thyristor operating angle reaches the adjusting purpose.

Signal receives

If selected the infrared signal reception, signal is received by integrated infrared receiving terminal, directly enters CPU from RA0, finishes infrared reception task;

When the carrier signal reception was selected to exchange by system, high-frequency signal was through C201, and the T1 primary coil (is used all coil racks among the 7.95MHz at present, according to coiling in 5: 5, the middle non-conductive fibre that adopts was isolated with diameter 0.13mm enameled wire, prevented that interlayer from puncturing), behind the C202, must be coupled to the T1 coil time utmost point, and the resonance frequency of secondary coil and C203 is 8MHz, this just makes the signal after coupling frequency can only be near the 8MHz, signal is through C204 filtering, and the D201 amplitude limit enters R201, R202, the amplifying circuit that Q201 (enlargement factor is between 200---250) forms, signal is coupled through T2 once more at collector, and R203 is a Power Limitation resistance, the method for making of T2 and T1 is identical, elementary and the C205 resonance frequency 8MHz of T2 makes the 8MHz signal be coupled to the utmost point once more T2 time, through C206 filtering, obtain purer 8MHz signal, deliver to IC201, R204, R205, R206, R208, the signal amplification shaping circuit that C207 forms, output signal is after the R207 current limliting, enter CPU from RA0, finish the reception task of carrier signal.

Power unit adopts resistance-capacitance depressurization, obtains the 5V direct supply after the filter rectification voltage stabilizing;

The principle of work explanation:

Microprocessor reads self coding earlier after startup, 6 encoder port like those shown of system are set to the data input port, play the coding effect by the form that loads high electronegative potential.With the concrete data that read the low 6 of special register of packing into; When system reads signal, preferentially read manual button, have just to carry out to transfer and turn operation greatly down according to concrete state.If there is not button to press, enters external data signal and receive trace routine.System can receive infrared signal and carrier signal.When receiving infrared signal, adopt infrared receiving module, obtain pulse signal after infrared signal is handled, offer microprocessor; During the reception carrier signal, earlier the 8MHz signal is coupled from the alternating current line of force, amplifies then, frequency-selecting 8MHz signal coupling once more, shaping obtains the pulse data string, offers microprocessor; After signal enters microprocessor, at first according to protocol mode (data-signal length agreement, under the 4MHz condition, about 2050 steps of marking signal, about 500 steps of gap signal, data " 0 " about 500 steps of signal, data " 1 " about 1300 steps of signal) receive, correct data are write special register, system hangs down 6 with data low 6 and code registers and compares, if it is identical, (" 11 " expression " is opened ", " the progressively increasing " when " 10 " expression is regulated, " 00 " expression " pass " just to carry out high 2 execution data resolution, " 01 " " successively decreasing " when expression is regulated), and carry out corresponding switch control and transfer and turn output control greatly down; Corresponding indication is provided.

Principles of Regulation are the interchange zero phase measuring abilities that utilize microprocessor itself to have, detect zero phase after, program output is the gap pulse signal of reference point with the zero phase, control external controllable silicon conduction angle; According to exchanging 50Hz, TMR0 function with microprocessor, set frequency dividing ratio, calculate the divider ratio of divider ratio, half ac cycle, a period of time after the zero phase and will finish negative half period to this zone of positive half cycle as insensitive zone of regulating, some time before being about to finish from positive half cycle begins wait, wait as the corrected AC zero phase, like this, even a-c cycle has subtle change, can not influence the normal operation of program yet;

During adjusting, set an adjusting special register, change numerical value by manual ringing or external data signal in certain limit, when surpassing this scope, program setting is an on off state, is carried out by switching programme; Do not have external signal to receive when regulating circulating working mode:

Detect and exchange zero phase------once-assignment detects manual ringing to TMR0------, and--------------------------secondary-assignment detects the count flag of TMR0, and-------------three times-assignment exchanges zero phase to TMR0-------and proofreaies and correct the count flag of inspection TMR0 in pulse to TMR0----------in pulse in anti-shake delay.Wherein,

Assignment+one pulse length+assignment+interchange zero phase is proofreaied and correct duration=half ac cycle for the third time for the first time,

Assignment+pulse length=half ac cycle for the second time,

Like this, operation once just is an ac cycle; During operation, be divided into and detect the interchange zero phase that-------first pulse is intact, first pulse is intact, and-------the second pulse is intact, second pulse is intact, and-------corrected AC zero phase three phases is set the special mark register, from each stage, just be set with this stage sign, which position cancellation when finishing through Mark Detection, is just known in;

Program considers that the signal reception may influence operate as normal, having set has signal just to enable the function that TMR0 interrupts, in service have interruption to produce, program jumps to interrupt service routine, through Mark Detection, carry out the interrupt handling routine of relevant position, cancel this interrupt function without external data signal, therefore, program can produce conditioning signal very stably.Control port by certain peripheral cell, by switch, is transferred the mode of turning down greatly, the light-adjusting and speed-adjusting of control AC electric appliance etc.
