Purpose.
Wherein, the processor of controller and air conditioner communicate to connect, and realize and control air conditioner.In family's power utilization environment
Air switch connects controller, and controller connects air conditioner.Controller is by checking total current and temperature at air switch, control
Air conditioner operation processed.Connection between controller and air conditioner is communication connection, and the communication connection includes one-way communication or double
To communication.
And in an embodiment of the present invention, in the communication of controller and air conditioner, in order to reduce the power consumption of controller,
The number of communications between controller and air conditioner can be reduced.Control command is sent to air conditioner in controller, which can
To be：Shutdown command, frequency reducing instruction, normal operation instruction or the control instruction for being to maintain current operation frequency etc..In every hair
It before the control instruction for sending a example above, or before sending above-mentioned control instruction next time, judges, if need
Control instruction is sent again.For example, being not repeated to send identical control instruction when the control instruction sent each time is identical
To air conditioner.
Specifically, the number of communications of control controller and air conditioner includes：
By taking controller and air conditioner two-way communication as an example, specific communication means is as follows：
When the state of controller judgement present air switch, which meets, sends shutdown command to air conditioner, then according to predetermined logical
Letter cycle T is communicated with air-conditioning.
When controller determines that the state that present air switchs meets the state sent other than shutdown command to air conditioner, then
Corresponding control instruction is sent to air conditioner, does not hereafter retransmit control instruction if meeting following two condition simultaneously:
1, the order confirmation that air conditioner returns has been received by the control instruction of controller transmission.
2, controller control instruction to be sent is identical as the last time.
When being unsatisfactory for any of the above conditions, is then communicated, hereafter repeated above-mentioned according to scheduled communication cycle T
Step.
In addition, the tripping critical-temperature of executing agency can according to the characteristic of the bimetal leaf of executing agency, tripping force with
And zeroing climb displacement obtains, further, the temperature rise of tripping force will receive the influence of zeroing stroke, the life of each air switch
Producer is produced in order to reach national standard all and zeroing stroke can be arranged to calibrate to air switch performance, thus is utilizing temperature
It is spaced apart the influence for needing to consider zeroing stroke when whether jumping disconnected foundation as judgement, it is critical in the tripping for calculating executing agency
When temperature, a reserved temperature constant is added as zero stroke is exchanged as amendment, can more accurately judge that air switch is
It is no to thread off.
Due to conventionally by electric current, the time these amount carries out calculating whether air switch will thread off some of introducing indirectly
Inevitable error.Also, in the error in judgement of air switch tripping, air conditioner power does not reduce in time, reduces total
When electric current in circuit, air switch has been threaded off, disconnecting circuit, at this point, being higher than the overcurrent energy of specified value part for total current
Power is fully utilized there is no the characteristic according to air switch, leads to the waste of home electrical.The present invention directlys adopt air
The internal temperature of switch saves the error for being judged by electric current and being introduced during time reckoning, more as anti-tripping foundation
Adding accurately and reliably prevents air switch from threading off, while avoiding the waste of home electrical, and air switch is utilized to greatest extent
Conveyance capacity.
In the present embodiment, controller gets the internal temperature of air switch, and the internal temperature of air switch is herein
Refer to the temperature of the executing agency inside air switch.Since the executing agency of home-use air switch is thermal tripping, setting is pre-
If temperature, the preset temperature be less than or equal to executing agency critical tripping temperature, judge air switch internal temperature whether
Greater than the preset temperature, the judgment basis anti-tripping as air switch using temperature.When the internal temperature of air switch is greater than in advance
If when temperature, may indicate that tripping closes in the executing agency of air switch, to prevent air switch from threading off, sends and drop to air conditioner
Power instruction reduces the electric quantity consumption of air conditioner, reduces the electric current in way circuit, and then prevent air switch from threading off.Using sky
The internal temperature of air cock more accurately and reliably prevents air switch from threading off as anti-tripping foundation, avoids home electrical
Waste, be utilized the conveyance capacity of air switch to greatest extent, ensure the normal work of other household electrical appliances in way circuit.
Further, referring to Fig. 3, the anti-tripping control method second embodiment of the present invention is based on above-mentioned first embodiment,
Before the step S20, further include：
Step S30, judges whether the electric current of the way circuit where the air switch is greater than the first predetermined current.
When the electric current of way circuit is greater than the first predetermined current, step S10 is executed, that is, obtains the inside temperature of air switch
Degree.
The numerical value of first predetermined current described in the present embodiment is less than or equal to the load current value of the air switch.By
A upper embodiment is it is found that the characteristic of thermal tripping air switch is, when the electric current for flowing through air switch is slightly above the volume of air switch
When constant current, when the temperature of the executing agency inside air switch reaches critical tripping temperature, air switch tripping, air switch
Place circuit disconnects.So it is default to judge whether the electric current of way circuit is greater than first before the internal temperature of acquisition air switch
Electric current then illustrates the current flow of way circuit to be close to or up to air when the electric current of way circuit is greater than the first predetermined current
The rated current of switch, at this time, it may be necessary to execute the internal temperature for obtaining air switch；And when the electric current of way circuit is less than or equal to
When the first predetermined current, it may be said that the current flow of bright way circuit is also not up to the rated current of air switch, and air is opened at this time
There are also certain distances apart from critical tripping temperature for executing agency's Current Temperatures of pass, obtain air switch it is therefore not necessary to execute
Internal temperature reduces anti-tripping control operating procedure to control the operation power of air conditioner.
Further, when the electric current of way circuit be less than or equal to the first predetermined current when, judge way circuit electric current whether
Less than the second predetermined current, wherein the second predetermined current is less than the first predetermined current.When the electric current in way circuit is pre- less than second
If when electric current, showing that the current value in current total current is lower, current value needed for executing agency's tripping apart from air switch
There are also larger difference, air conditioner not will lead to air switch generally also according to the operation program operation of air conditioner itself and thread off, because
This, sends to air conditioner operate normally instruction at this time, to control air conditioner normal operation, ensures that the air conditioning of air conditioner is made
With.When the electric current in way circuit is greater than or equal to the second predetermined current, although air switch is also not in de- in the short time
Button, but at this time should suitable control air conditioner electric current occupancy, compressor frequency is excessively high when air conditioner being avoided to operate normally leads
It causes the electric current in way circuit excessive, air switch is caused to thread off, therefore, sent to air conditioner keep current frequency operation at this time
Instruction remains less than or is equal to current operation frequency operation to control the compressor frequency of air conditioner.In general, the second predetermined current
Value be the first predetermined current 50%-90%, but be not limited to this value range, the specific value of the second predetermined current
The performance of the corresponding air conditioner of specific controller should be also investigated, on the one hand the second predetermined current value is as big as possible, so that
Air conditioner can be operated normally when the electric current in way circuit is less than the second predetermined current, and guarantee air conditioner is in normal as far as possible
The operating status of operation；On the other hand it in general, ensureing that the second predetermined current value is reasonable, avoids that current frequency operation is kept also
Leading to the electric current in way circuit is more than the rated current of air switch, increases the risk of air switch tripping.
In addition, the electric current of real-time monitoring way circuit immediately after controller powers on, according to the current situation of way circuit and
The temperature conditions of air switch sends corresponding control instruction to air conditioner, is run with controlling air conditioner according to control instruction, prevents
Only air switch is threaded off, and causes circuit to disconnect, other household electrical appliances can not work normally.It should be pointed out that air conditioner is after the power-up
The control instruction that air conditioner is sent is received, the control instruction issued afterwards covers previous control instruction, so air conditioner receives
Control instruction be the controller that receives finally is sent after air conditioner powers on control instruction.
In the present embodiment, before the internal temperature for obtaining air switch, first determine whether which the electric current of way circuit meets
Kind condition.When the electric current of way circuit is greater than the first predetermined current, then illustrate the current flow of way circuit to be close to or up to sky
The rated current of air cock executes step S10 to prevent air switch from threading off；When the electric current of way circuit is less than the first predetermined current
When, judge the electric current of way circuit whether less than the second predetermined current.When the electric current of way circuit is less than the second predetermined current,
Show that the current value in current total current is lower, there are also larger differences for current value needed for executing agency's tripping apart from air switch
Value, air conditioner not will lead to air switch generally also according to the operation program operation of air conditioner itself and thread off, send to air conditioner
Instruction is operated normally, to control air conditioner normal operation, ensures the air conditioning effect of air conditioner；When the electric current in way circuit is small
In or be equal to the first predetermined current and be greater than or equal to the second predetermined current when, should suitable control air conditioner electric current occupy
Amount, the excessively high electric current caused in way circuit of compressor frequency is excessive when air conditioner being avoided to operate normally, and air switch is caused to thread off,
The instruction for keeping current frequency to run then is sent to air conditioner, is remained less than or with controlling the compressor frequency of air conditioner equal to working as
Preceding running frequency operation.Different control instructions is sent to air conditioner according to the current size of current of way circuit, prevents air from opening
While closing tripping, guarantees the air handling capacity of air conditioner, improve the working efficiency of air conditioner.
Further, referring to Fig. 4, the anti-tripping control method 3rd embodiment of the present invention is based on the above-mentioned first or second
Embodiment before the step S20, further includes：
Step S40, judges whether the internal temperature of the air switch is greater than the preset temperature.
Step S50, when the internal temperature of the air switch is less than or equal to the preset temperature, to the air conditioner
