Detailed description of the invention
Fig. 1 is the structural schematic diagram of the embodiment of the present invention.
Fig. 2 is control method flow diagram of the invention.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.
One kind being based on the energy-efficient intelligent control method of central air-conditioning terminal, and Fig. 1 is the structural schematic diagram of intelligent controlling device,
Intelligent control module, display module, burning module, indicating module and mode switch module, the intelligent control module include:
Communication interface unit controls the relay control coil of fan coil blower and water valve and is for detecting in temperature controller
It is electricly no, the start and stop state of the room central air conditioning fan coil unit is learnt with this.
Power supply unit, for providing power supply for entire intelligent controlling device and display module.
Output control unit, the control command given for receiving control unit control signal to temperature controller, control blower
Coil pipe start and stop.
Level conversion unit, for communication interface unit incoming level and the progress of control unit input requirements voltage
Match.
Control unit compares current time and central hollow is closed in setting for receiving the status signal of fan coil start and stop
Between timing, according to built-in algorithm, control command is exported.
Clock unit, for providing real-time time information to control unit.
Power down holding unit, for maintaining the normal operation of clock unit clock under power-down conditions.
Push-button unit, for adjusting the time of clock and setting closing central air-conditioning in clock chip.

Burning module, for carrying out burning program to control unit.
Mode switch module, for being applicable in three kinds of operation, parameter setting and burning program situations.
Communication interface unit, has the function of detecting that central fan coil is in operating status or closed state.Due to
The level for detecting the relay of corresponding control fan coil blower and water valve is more than that control unit input can bear voltage
Maximum value need to provide fan coil start and stop state after level conversion unit carries out electrical level match, then to control unit, as control
One of the judgment basis of unit control output processed.
Power supply unit is clock unit, control unit, level as the source of energy needed for entire intelligent controlling device
Converting unit, indicating module, display module provide power supply；Trickle current is carried out to power down holding unit by clock unit to fill
Electricity.Under parameter setting mode, by display module access multiplexing interface, power module provides power supply for display module at this time.
Output control unit passes through as the outgoing route that intelligent controlling device control unit controls electronic thermostat
Temperature controller controls central air conditioning fan coil unit blower and valve switch, to control the operating status of fan coil.
Level conversion unit, as the medium of intelligent control unit, to communication interface unit incoming level and control unit
Input requirements voltage is matched.The voltage output as provided by power supply unit in the input voltage range of control unit,
Level switch module, using PNP triode switching characteristic, realizes communication interface unit institute using the output of power supply unit as power supply
Detecting state signal matches with control unit input voltage.
Control unit, as the core of intelligent controlling device, by compare the real-time time read in clock unit with
The set closing fan coil time, as timing judgment basis, in combination with the fortune of detected central air conditioning fan coil unit
Row state, according to built-in algorithm, to determine exported control command.
Clock unit provides current real-time time as intelligent controlling device clock signal source for control unit, gives institute
Fan coil shut-in time offer benchmark is provided.The setting of the clock unit built-in time is the connection in the case where & burning mode is arranged
Display module carries out time setting by push-button unit to multiplex interface.The crystal oscillator of the external 32.768kHz of clock unit, the crystalline substance
Vibration forms oscillator for generating reference clock signal, with the circuit inside clock unit, divided that accurate second letter can be obtained
Number.The clock unit uses dual power supply, and under normal operation, power supply unit is clock unit power supply, while can be power down
Holding unit carries out trickle current charging；Under power blackout situation, clock unit maintains clock by external power down holding unit
Unit internal time.
Power down holding unit ensure that under unexpected power-down conditions as power supply module of the clock unit under power-down conditions,
The duration of clock unit internal clocking.The power down of this intelligent controlling device keeps power supply using 3.6V rechargeable lithium battery,
Under clock unit normal operation, trickle current charging can be carried out to the power down holding unit.
Push-button unit is made of three key switches altogether, all parameter settings as the input unit of parameter setting
There is the various combination of these three keys to complete.The function having by push-button unit: display parameters, into parameter setting,
Confirmation parameter setting, shifting function, number adds one at cursor flashing, and number subtracts one, exits and do not save parameter and set at cursor flashing
It sets, exit and save parameter setting.
Display module is intelligent controlling device and the unit that user interacts.If being in the case where & burning mode is arranged
Display module is connect in multiplex interface and without any operation, then NULI character on display module, enters display parameters function by key,
The time that current real-time time and set central air conditioning fan coil unit are closed then is shown on display module；By key,
When into parameter setting, cursor can be in the highlighted flashing of the first character bit, in confirmation parameter setting or after carrying out shifting function, light
Mark is displaced at next character for needing to be arranged and highlights flashing；After all characters all confirmation, cursor highlight flashing disappears；It moves back
It does not save parameter setting out or exits and save parameter setting, display module NULI character.
Mode switch module, as the operating block that intelligent controlling device different function is realized, altogether two grades of modes.One grade is
Device operational mode, in this mode, intelligent controlling device is connected with temperature controller, realizes the control to central air conditioning fan coil unit
System；Another shelves are setting & burning mode, and the set of modes both of which, one kind is parameter setting mode, and another kind is burning mould
Formula, this both of which share one grade.Therefore mode switch module can be applicable in three kinds of operation, parameter setting and burning program feelings
Shape.
The present invention also provides one kind to be based on the energy-efficient intelligent control method of central air-conditioning terminal, and Fig. 2 is control of the invention
Above-mentioned apparatus can be used in method flow schematic diagram, this method, comprising the following steps:
(1) the current implementation time in clock unit is read；
(2) judge to realize whether the key combination of " display parameters function " is triggered, if not being triggered, skip to step
(5)；
(3) parameter adjustment is carried out；
(4) judgement realizes that the key combination of " exit and adjust ginseng function " (exit and do not save parameter, exit and save parameter) is
It is no to be triggered, if being triggered, step (1) is skipped to, if not being triggered, skips to step (3)；
(5) judge whether current real-time time is setting value, if current real-time time is not to close central air conditioner fan disk
The setting value of pipe then skips to step (1)；
(6) whether in operating status judge current fan coil, if being not at operating status, skip to step (1)；
