Specific embodiment
To keep the embodiment of the present invention, technical solution and advantage more obvious, below in conjunction with attached drawing to skill of the invention
Art scheme is clearly and completely described, it is clear that and the embodiment described is a part of the embodiments of the present invention, rather than all
Embodiment.It will be apparent to a skilled person that these embodiments are used only for explaining technical principle of the invention, and
It is not intended to be limiting protection scope of the present invention.In addition it is also necessary to illustrate, the term " first ", " second " in the present invention are only
For descriptive purposes, it is not understood to indicate or imply relative importance.
With reference first to Fig. 1, air-conditioning line control machine power supply communication circuit of the invention includes being connected to air-conditioning line control machine and interior
Two core buses (first the+the second bus of bus) between machine, communicating circuit and power supply electricity between air-conditioning line control machine and indoor device
Road shares the two cores bus, and is provided with controllable switch in two core buses.When controllable switch is in the conductive state, communicating circuit
It does not work, indoor unit is powered by power supply circuit to air-conditioning line control machine；When controllable switch is in close state, power supply circuit is not
Work, indoor unit are communicated with air-conditioning line control machine by communicating circuit.As an example, controllable switch is triode, and should
Triode is parallel with resistance.In the case of triode disconnects, which plays the role of current-limiting protection.Power supply of the invention and
Communication is realized using same harness, instead of supply lines+connection mode before, is reduced harness, is reduced wiring failure rate.
Compared with prior art, air-conditioning line control machine power supply communication circuit of the invention needs not move through inductance, it is only necessary to select
Select the general controllable switch in market, such as triode, and it is not stringent to the current requirements of air-conditioning line control machine, it can realize display effect
The power supply for the line control machine that fruit is preferable, function is richer and communication need.Also, communicating circuit of the invention is to utilize analog device
The circuit of (optocoupler and triode etc.) composition.Compared with prior art, power supply communication circuit of the invention is not needed using integrated
Chip can realize power supply and communication, and limit without the type selecting of peripheral electron component.
Specifically, when triode ON, power supply circuit work, at this point, indoor unit can be supplied directly to air-conditioning line control machine
Capacitor charging electric and to air-conditioning line control machine；When triode disconnects, communicating circuit work, air-conditioning line control machine is utilized certainly at this time
The capacitances to supply power of body, communicating circuit carry out transmitting-receiving communication by the circuit of the analog devices such as optocoupler and triode composition；Communication knot
Shu Hou, triode normally, indoor unit is directly to the power supply of air-conditioning line control machine and to the capacitor charging of air-conditioning line control machine.This hair
The bright on-off using triode switches power supply circuit and communicating circuit, when band carries high-power line control machine, it is only necessary to replacement pressure resistance
Value, the higher power supply transistor of current value.Power supply communication circuit of the invention does not need IC chip, while eliminating stringent matching
The peripheral circuit of chip.
More specifically, referring to Fig. 2, in air-conditioning line control machine power supply communication circuit of the invention, in power supply and communication use
Mode when concluding realizes switching, divides the work in two core buses work according to default timing.Normal communication mechanism as shown in Fig. 2,
After detecting synchronization signal, timing 500us, air-conditioning line control machine sends data, indoor unit timing 500us, and indoor unit receives and dispatches number
According to.Free time is equivalent to no communication, is power-on time.It should be noted that power supply and communication succession, according to communication speed and power supply
Length of time can voluntarily be determined by software and communications protocol.
As an example, referring to Fig.1, it is in series with relay in the first bus, and in the state of relay conducting, line control machine energy
Enough by the conducting of triode and indoor unit be powered with communicate between switching.So, it can may be implemented to utilize
Line control machine controls the purpose of multiple indoor units simultaneously.Specifically, in the case where there is multiple indoor units, indoor unit by dial-up or
Person the modes such as competes automatically and realizes principal and subordinate's indoor unit (being main indoor unit in controlled state, others is from indoor units) really
Recognize, at this time the relay conducting of main indoor unit, and passes through the conducting and disconnection of triode, realize the power supply to line control machine and lead to
Interrogate data transmitting switching.That is, in the case where there is multiple indoor units, when line control machine needs to control wherein indoor unit A,
Keep the relay of indoor unit A in the conductive state, the relay of other indoor units is in an off state, and utilizes line traffic control to realize
Device controls the purpose of multiple indoor units simultaneously.
In conclusion the present invention replaces integrated IC chip and its peripheral circuit using simple electronic component, in air-conditioning
On indoor unit plate and air-conditioning line control machine bus, the requirement for powering but also meeting communication not only may be implemented, it is at low cost, and outside chipless
The stringent limitation of peripheral device.In addition, being turned off using triode ON, realizes power supply and communication switching, utilize general part triode
Type selecting, large power air-conditioned line control machine and small-power air-conditioning line control machine can be compatible with, without because line control machine power problem replace
Or the chip peripheries circuit devcie such as custom-made inductance.
It will be appreciated to those of skill in the art that the type selecting of various components among the above is according to actual application demand
It is matched, selects suitable model.In addition, controllable switch of the invention also can choose other suitable members in addition to triode
Device, such as diode, field transistor etc..
As a kind of specific embodiment, referring to Fig. 3, Fig. 3 is the one of air-conditioning line control machine power supply communication circuit of the invention
The detailed structure view of kind embodiment.As shown in figure 3, in this embodiment, air-conditioning line control machine power supply communication circuit is using simulation electricity
Road component replaces integrated chip, replaces integrated chip and integrated chip periphery by the simple component such as optocoupler and triode
Circuit.Power supply and communication are realized using same harness, instead of supply lines+connection mode before, are reduced harness, are reduced
Wiring failure rate.There is no the limitation of integrated chip peripheral circuit, it can be with the high-power line control machine of load.Triode ON, air conditioning chamber
Interior machine powers directly to line control machine while to the capacitor charging of line control machine.Triode shutdown, communicating circuit work, sending and receiving data.
It communicates and powers according to timing in bus division of labor work, realized by the way of interrupt timing.Power supply and communication succession, according to logical
Rate and power-on time length are interrogated, can voluntarily be determined by software.Components selection is according to actually being matched.
So far, it has been combined preferred embodiment shown in the drawings and describes technical solution of the present invention, still, this field
Technical staff is it is easily understood that protection scope of the present invention is expressly not limited to these specific embodiments.Without departing from this
Under the premise of the principle of invention, those skilled in the art can make equivalent change or replacement to the relevant technologies feature, these
