Referring to fig. 2, in a first embodiment, the present invention provides a control method of an air conditioner, including:
step S1, the anti-tripping control device establishes a home anti-tripping control network between the anti-tripping control device and a plurality of air conditioners;
in this embodiment, after the air conditioner is powered on for the first time, the anti-tripping control device needs to determine and store the address identification code of the air conditioner. Specifically, in a wired or wireless communication mode, for a wired communication mode, after the air conditioner is powered on, the identification codes of the air conditioner, which are received by the anti-tripping control device, are all the air conditioners within the authority range, and shielding work is not needed; however, for the wireless communication mode, the anti-tripping control device needs to add the function of shielding the air conditioner outside the authority range. The air conditioner outside the shielding authority range of the anti-tripping control device has the following functions: when the anti-tripping control device is powered on to work, the anti-tripping control device receives communication information from the air conditioners working around, identifies which air conditioners are in the authority range, and excludes the air conditioners when the air conditioners are judged to be out of the authority range.
The anti-tripping control device establishes a home anti-tripping control network between the anti-tripping control device and a plurality of air conditioners, and the specific mode can be operated by a mobile terminal such as a mobile phone, a tablet personal computer and the like, or certainly, the mobile terminal can not be used. The details will be described below, and will not be described in detail here.
Assuming that the total power limit of the household power of the user is 1200W, three air conditioners are installed in the household of the user, the power of the first air conditioner 1 is 700W, the power of the second air conditioner 2 is 800W, and the power of the third air conditioner 3 is 600W. After the three air conditioners are powered on for the first time, the three air conditioners are selected to be connected into a household anti-trip control network.
Step S2, when receiving the work requirement information that the air conditioner sends that the internal unit is started and the external unit needs to be started, marking the work requirement flag of the corresponding air conditioner as valid;
in this embodiment, the address identification code of the air conditioner includes two parts of information, one part is an identification code for distinguishing each air conditioner, and the other part is an identification code for distinguishing a fixed-frequency air conditioner and a variable-frequency air conditioner. The anti-tripping control device numbers the address identification code of the air conditioner stored in the anti-tripping control device, and assigns a working required state bit and a working state zone bit to the address identification code of each number, wherein the working required state bit and the working state zone bit can be composed of one bit or multiple bits. For example, a bit is assigned as a flag bit, 0 for off, and 1 for on. The working requirement state bit is used for judging whether the air conditioner needs to work or not. When a user starts the air conditioner by using a remote controller or an operation interface, the outer unit of the air conditioner does not work, the air conditioner sends information that the inner unit is started and the outer unit needs to be started to the anti-tripping control device, and the anti-tripping control device marks the working required state of the air conditioner as effective after receiving the information.
Step S3, obtaining the types of the plurality of air conditioners according to the household anti-tripping control network, and setting the working sequence of the air conditioners according to the types of the air conditioners;
in this embodiment, two air conditioners are taken as an example for explanation, wherein the fixed-frequency air conditioner is numbered 1, and the variable-frequency air conditioner is numbered 2, and when both the two air conditioners have work needs, the work order of the two air conditioners can be set to 1 and then 2, that is, the fixed-frequency air conditioner is preferentially ensured to work normally, and the variable-frequency air conditioner correspondingly reduces power or stops running according to the total power of the current circuit. Of course, in other embodiments, it may also be prioritized to ensure normal operation of the inverter air conditioner, and the fixed-frequency air conditioner is controlled to correspondingly stop operating according to the total power of the current circuit.
Step S4, according to the working sequence, sending an external unit starting instruction to the air conditioner with the working requirement flag bit marked as effective so as to control the air conditioner to start and operate;
in the present embodiment, it is assumed that the air conditioners 1 and 3 are now on and the air conditioner 2 is not on. Through user operation, both the air conditioner 1 and the air conditioner 3 turn on the internal machine and send work requirement information to the anti-tripping control device. And after receiving the information of the air conditioner 1 and the air conditioner 3, the anti-tripping control device turns the working requirement flag bit of the air conditioner 1 and the air conditioner 3 into valid. The anti-tripping control device firstly sends an external unit starting instruction to the air conditioner 1 according to the working sequence of the air conditioner so as to control the operation of the air conditioner 1.
When the running time of the air conditioner 1 reaches the preset time, a closing instruction is sent to the air conditioner 1, then the working process of the air conditioner 2 is entered, and the working process of the air conditioner 2 can be skipped because the working requirement flag bit of the air conditioner 2 is invalid, and the working process of the air conditioner 3 can be directly entered, and the control method of the anti-tripping control device on the air conditioner 3 is the same as that of the air conditioner 1, which is not described herein again.
It can be understood that when the number of the air conditioners in the household anti-tripping control network is 1, when the working requirement flag bit of the air conditioner is marked as effective, an external unit starting instruction is sent to the air conditioner to control the air conditioner to start and operate; and when the number of the air conditioners in the household anti-tripping control network is 2 or more, sending an external unit starting instruction to the air conditioner with the working requirement flag bit marked as effective according to the preset working sequence of the air conditioners so as to control the corresponding air conditioner to start and operate.
And step S5, controlling the operation state of the air conditioner according to the size relation between the detected total power of the current circuit and a preset power threshold value in the operation process of the air conditioner.
In this embodiment, after the air conditioner is started, in the operation process of the air conditioner, the total power of the current circuit does not exceed the preset power threshold and exceeds the preset power threshold, and the operation state of the air conditioner can be correspondingly controlled according to the two situations.
Specifically, when the currently operating air conditioner is a fixed-frequency air conditioner or a variable-frequency air conditioner, if the total power of the current circuit does not exceed a preset power threshold, the operating state of the current fixed-frequency air conditioner or the variable-frequency air conditioner is kept unchanged; when the air conditioner in current operation is a fixed-frequency air conditioner, if the total power of a current circuit exceeds a preset power threshold value, directly controlling the fixed-frequency air conditioner to stop operating; when the air conditioner in current operation is a variable frequency air conditioner, if the total power of the current circuit exceeds a preset power threshold value, the variable frequency air conditioner is controlled to operate in a frequency reduction mode, and if the total power of the current circuit still exceeds the preset power threshold value, the variable frequency air conditioner is controlled to stop operating.
When the currently operating air conditioner includes both a fixed-frequency air conditioner and a variable-frequency air conditioner, if the total power of the current circuit does not exceed a preset power threshold, the operating states of the current fixed-frequency air conditioner and the variable-frequency air conditioner can be kept unchanged, the two types of air conditioners can be subjected to mutually restricted frequency operation control, and the two types of air conditioners can be subjected to combined control, which will be specifically described in detail below; if the total power of the current circuit exceeds a preset power threshold, the variable frequency air conditioner can be controlled to operate in a frequency reduction mode, if the total power of the current circuit still exceeds the preset power threshold, the variable frequency air conditioner is controlled to stop operating, and finally the fixed frequency air conditioner is controlled to stop operating.
The control method of the air conditioner provided by the invention establishes a household anti-tripping control network between the air conditioner and the air conditioners through the anti-tripping control device, then when receiving the information which is sent by the air conditioner and is needed by the indoor unit being started and the work of the outdoor unit being needed to be started, marking the working requirement flag bit of the corresponding air conditioner as effective, then obtaining the types of the plurality of air conditioners according to the household anti-tripping control network, setting the working sequence of the air conditioner according to the type of the air conditioner, further sending an external unit starting instruction to the air conditioner with the working requirement flag bit marked as effective according to the working sequence so as to control the air conditioner to start and operate, and finally in the operation process of the air conditioner, and controlling the running state of the air conditioner according to the magnitude relation between the detected total power of the current circuit and a preset power threshold value. Therefore, the tripping phenomenon of the circuit breaker can be prevented by controlling the working states of different types of air conditioners under the condition that the household power consumption is limited.
In the second embodiment, referring to fig. 3, based on the first embodiment, the step S4 includes:
step S41, according to the working sequence, sending an external machine starting instruction to the air conditioner with the first working sequence and the working requirement flag bit marked as effective so as to control the air conditioner with the first working sequence to operate;
step S42, starting a timer for timing;
step S43, when the timer overflows, marking the working state identification bit of the air conditioner with the first working sequence as invalid, and sending a closing instruction to the air conditioner with the first working sequence to control the air conditioner with the first working sequence to stop running;
in this embodiment, according to the working sequence, an external unit starting instruction is sent to the air conditioner with the first working sequence and the working requirement flag bit being marked as valid. And when the air conditioner with the first working sequence starts to operate, starting a timer to start timing, and if the air conditioner 1 receives an external unit starting instruction, starting the external unit and starting to operate. When the timer overflows, the anti-tripping control device marks the working state flag bit of the air conditioner 1 as invalid and sends a closing instruction to the air conditioner 1 to control the air conditioner 1 to stop running.
Step S44, acquiring a working state identification position of the air conditioner with the second working sequence;
in this embodiment, since the air conditioners are air conditioner 1, air conditioner 2, and air conditioner 3 … in the working order, and so on, when the air conditioner 1 stops operating, the anti-tripping control device controls to enter the working process of the air conditioner 2, and obtains the working state flag bit of the air conditioner 2.
And step S45, when the working state identification bit of the air conditioner with the second working sequence is valid, sending an external unit starting instruction to the air conditioner with the second working sequence to control the air conditioner with the second working sequence to operate.
In this embodiment, if the working state flag of the air conditioner with the second working order is valid, which indicates that the external unit is turned on, the external unit turn-on instruction is sent to the air conditioner with the second working order. Similarly, when the air conditioner with the second working sequence starts to run, the timer is started to start timing, and when the timer overflows, the anti-tripping control device marks the working state flag bit of the air conditioner 2 as invalid and sends a closing instruction to the air conditioner 2 to control the air conditioner 2 to stop running.
And step S46, when the working state identification bit of the air conditioner with the second working sequence is invalid, directly skipping the working process of the air conditioner with the second working sequence.
In this embodiment, if the working state flag of the air conditioner with the second working order is invalid, the working process of the air conditioner with the second working order is directly skipped. Since the flag bit is invalid for the operation of the air conditioner 2, the working process of the air conditioner 2 can be skipped and the operation can be directly performed in the working process of the air conditioner 3.
It can be understood that, when the air conditioner is controlled to stop operating, it is still controlled that the external unit of the air conditioner stops operating, and therefore, the present invention mainly controls the on and off of the external unit of each air conditioner. Of course, in other embodiments, the internal unit of the air conditioner may be controlled to be turned off.
In the third embodiment, based on the first embodiment, the step S5 further includes:
in the air conditioner operation process, if the air conditioner type of current operation includes fixed frequency air conditioner and inverter air conditioner, then when detecting that total power is greater than the preset power threshold value, and be less than first factor of safety with when presetting the product of power threshold value, control fixed frequency air conditioner normal operating, and control inverter air conditioner moves that reduces the frequency.
In this embodiment, the method for performing combined control on two types of air conditioners, namely, the fixed-frequency air conditioner and the variable-frequency air conditioner, is as follows:
