Operation principle of the present invention and the course of work as shown in Figure 4, comprise as follows:
After the power on/off module of split-type air conditioner intelligent supervisor of the present invention supply civil power, correspondingly air-conditioning also just energising.After air-conditioning energising (when using this equipment for the first time, air-conditioning remote control is aimed at this equipment, by button any on air-conditioning remote control, launch infrared coded signal, this equipment, by infrared receiver transtation mission circuit, receives this signal, MCU control circuit is through intelligent computing and analysis, find out the infrared coding that the infrared coding be stored in memory circuit is corresponding with the air-conditioning remote control be managed, find out infrared coding, so as the identification of this equipment and remember oneself manage the model specification of air-conditioning; This equipment launches once " pass air-conditioning " infrared coded signal afterwards, is closed by air-conditioning, and power detection module detects power during air-conditioner standby, and power data during air-conditioner standby is sent to control circuit to preserve.Afterwards with regard to no longer carrying out these two operations, if the air-conditioning of different model specification will be managed, need again to carry out these two operations), each module initialization in this equipment.
MCU control circuit reads the air-conditioning power that this equipment working environment humiture, system time and testing circuit detect.MCU control circuit continues to monitor afterwards: every 5 minutes of the present embodiment MCU control circuit timing, the power signal that readout power testing circuit detects, with preserve air-conditioner standby power ratio comparatively, judge that (power detected is greater than the air-conditioner standby power of preservation, and air-conditioning is in " opening operation " state for the running status of air-conditioning; The power detected is less than or equal to the air-conditioner standby power of preservation, and air-conditioning is in " turning off standby " state); Every 1 minute, read a humiture and system time, compare with the time of turning on the aircondition arranged and humiture, comparative result is as follows:
(1) arranging within the time of turning on the aircondition, now, the air-conditioning power that MCU control circuit readout power testing circuit detects, with preserve air-conditioner standby power ratio comparatively, judge the duty of air-conditioning: if air-conditioning is in " opening operation " state, MCU control circuit does not send instruction to air-conditioning; If air-conditioning is in " turning off standby " state, " turning on the aircondition " infrared coding of MCU control circuit reading and saving, controls infrared receiver radiating circuit, launches " turning on the aircondition " infrared coded signal, opens air-conditioning.
(2) outside the time of turning on the aircondition arranged, now, MCU control circuit is the humiture read and humiture thresholding (the such as temperature 25 DEG C preset, humidity is 50%, this is warm and humid suitable because of people, according to oneself need adjustment) make comparisons: if meet the humiture threshold condition of setting, MCU control circuit readout power judges that whether air-conditioning is in " opening operation " state, if not, just send " turning on the aircondition " infrared coded signal and open by it to air-conditioning.If do not meet the humiture threshold condition of setting, control module readout power judges that whether air-conditioning is in " turning off standby " state, if not, just send " pass air-conditioning " infrared coded signal and close by it to air-conditioning.Concrete point " refrigeration mode ", " heating mode " and " dehumidification mode " three kinds:

2. temperature is lower than the temperature preset: MCU control circuit readout power judges air-conditioning state: if air-conditioning is in " turning off standby " state, and MCU control circuit does not send instruction to air-conditioning; If air-conditioning is in " opening operation " state, now temperature is lower than preset temperature certain value (such as 5 DEG C or 10 DEG C), " pass air-conditioning " infrared coding of reading and saving, control infrared receiver radiating circuit, launch " pass air-conditioning " infrared coded signal to close by it to air-conditioning, now detection power, judges air-conditioning state, if air-conditioning is not closed, then continue this operation until air-conditioning is closed.
Heating mode:
1. temperature is lower than the temperature preset: MCU control circuit readout power judges air-conditioning state: if air-conditioning is in " turning off standby " state, " turning on the aircondition " infrared coding of reading and saving, control infrared receiver radiating circuit, launch " turning on the aircondition " red code signal to open by it to air-conditioning, now detection power, judge air-conditioning state, if air-conditioning is not opened, then continue this operation until air-conditioning is opened; If air-conditioning is in " opening operation " state, MCU control circuit does not send instruction to air-conditioning.
2. temperature is higher than the temperature preset: MCU control circuit readout power judges air-conditioning state: if air-conditioning is in " turning off standby " state, and MCU control circuit does not send instruction to air-conditioning; If air-conditioning is in " opening operation " state, now temperature is higher than preset temperature certain value (such as 5 DEG C or 10 DEG C), " pass air-conditioning " infrared coding of reading and saving, control infrared receiver radiating circuit, launch " pass air-conditioning " infrared coded signal to close by it to air-conditioning, now detection power, judges air-conditioning state, if air-conditioning is not closed, then continue this operation until air-conditioning is closed.
Dehumidification mode:
1. humidity is higher than the humidity preset: MCU control circuit readout power judges air-conditioning state: if air-conditioning is in " turning off standby " state, " turning on the aircondition " infrared coding of MCU control circuit reading and saving, control infrared receiver radiating circuit, launch " turning on the aircondition " infrared coded signal, open by it to air-conditioning, now detection power, judge air-conditioning state, if air-conditioning is not opened, then continue this operation until air-conditioning is opened.If air-conditioning is in " opening operation " state, MCU control circuit does not send instruction to air-conditioning.
2. humidity is lower than the humidity preset: MCU control circuit readout power judges air-conditioning state: if air-conditioning is in " turning off standby " state, and MCU control circuit does not send instruction to air-conditioning; If air-conditioning is in " opening operation " state, now humidity is lower than default humidity certain value (such as 10%), " pass air-conditioning " infrared coding of reading and saving, control infrared receiver radiating circuit, launch " pass air-conditioning " infrared coded signal to close by it to air-conditioning, now detection power, judges air-conditioning state, if air-conditioning is not closed, then continue this operation until air-conditioning is closed.
The control flow of above-mentioned control module is worked out according to routine techniques by the programming personnel of this area, and embeds in advance in MCU control circuit.
