The air conditioner installation place in the present embodiment refers to a place where the air conditioner is used, such as a home, a company, a school, or a factory. The real-time current of the electricity consumption at the air conditioner setting position refers to the real-time current of the electricity consumption detected by the input end of the main circuit in the place.
The present embodiment takes a household power consumption scenario as an example, and when a household needs more than one air conditioner to work, the present invention provides a control method for an air conditioning system in order to cause a power failure when a household power consumption current does not exceed a rated household power consumption current when the air conditioner works.
The air conditioning system in this embodiment is an outage-preventing air conditioning system, and the air conditioning system includes a total current detection module, a controller, and an air conditioner, and in addition, a user can interact with a mobile terminal and the controller, and the mobile terminal can interact with the controller. The household power supply system comprises a household circuit input end, a household circuit breaker, a total current detection module, a power supply module and a power supply module, wherein the total current detection module is connected between the household circuit input end and the household circuit breaker and continuously detects the current of household power consumption; the mobile terminal downloads corresponding interactive software, and a control algorithm is preset in the software, so that a corresponding air conditioner working scheme can be formulated according to the number of the household air conditioners, the air conditioner working scheme is pushed to a user, and the user can customize the air conditioner working scheme in the interactive software; the controller can perform operations of turning on, turning off or reducing power on the air conditioner; a control circuit is arranged in the air conditioner.
It can be understood that the operation of turning on, turning off or reducing power of the air conditioner performed by the controller is realized by the controller sending a power-on, turning off or reducing command to the air conditioner, and after the air conditioner receives the corresponding command, the control circuit in the air conditioner performs the corresponding power-on, turning off or reducing operation.
The total current detection module, the mobile terminal, the controller and the air conditioner are all provided with communication modules, and the communication modules can be Bluetooth modules or Wi-Fi modules. Through the communication module, a communication relation can be established among the total current detection module, the mobile terminal, the controller and the air conditioner. It should be noted that, in the present embodiment, all the devices in the air conditioning system are in the power-on state.
In the present embodiment, the air conditioning control network is first established. Specifically, a user operates the air conditioner and the controller to enter a configuration mode, and in the configuration mode, the air conditioner and the controller send identification codes to other equipment in the air conditioning system through the communication module. The identification code is preset according to the identification information, type (constant speed and variable frequency) and power consumption of the air conditioner. For example, assuming that there are two air conditioners in the air conditioning system, the identification codes of the two air conditioners can be preset to 0000101600 and 0000200500, where 00001 and 00002 are the identifications of the air conditioners, 01 represents a constant speed, 00 represents a variable frequency, and 600 and 500 represent power consumption. After the mobile terminal receives the identification code, the user defines a unique name corresponding to each air conditioner according to the identification code, where the unique name includes identification information, type (fixed speed and variable frequency), power consumption, and operating time, and for example, the unique name of the fixed speed air conditioner is defined as 0101600, and the name of the variable frequency air conditioner is defined as 200500. It should be noted that the special name has a certain naming standard, and the user can refer to a naming manual to define the special name corresponding to each air conditioner. When the user sets the special name of the air conditioner at the mobile terminal, the special name of the air conditioner is used as a pass of the control system, namely, the user or the controller sends an instruction, other equipment in the air conditioner system can recognize the special name and further make a corresponding response, and the establishment of the air conditioner control network is completed.
After the air conditioner control network is established, the interactive software of the mobile terminal formulates a corresponding air conditioner working scheme according to the number and the type of the air conditioners through a preset control algorithm for selection of users. For example, if a user has two air conditioners in a home, which are a constant speed air conditioner and a variable frequency air conditioner, respectively, the air conditioner working scheme made by the interactive software may be: (1) the constant speed air conditioner works, and the variable frequency air conditioner does not work; (2) the constant speed air conditioner and the variable frequency air conditioner work simultaneously; (3) the constant speed air conditioner does not work, the variable frequency air conditioner works, and then the user can select a corresponding working scheme according to the requirement.
In more implementation, a user can customize an air conditioner working scheme in interactive software of the mobile terminal, the interactive software evaluates whether the air conditioner working scheme customized by the user is reasonable or not by combining information provided by a special name of the air conditioner, and when the customized air conditioner working scheme obtained after evaluation is unreasonable, a corresponding modification scheme is formulated for the user to select.
In this embodiment, after the user selects the air conditioner working scheme, the mobile terminal sends a corresponding air conditioner working instruction to the outage-prevention air conditioner control system, and when the air conditioner receives the air conditioner working instruction, the air conditioner corresponding to the air conditioner working instruction starts an air conditioner internal unit, and the air conditioner external unit is not started. It should be noted that, when the internal unit of the air conditioner is turned on and the external unit is not turned on, the air conditioner is in a corresponding non-operating state. The air conditioner in the working scheme of the air conditioner can be one air conditioner or a plurality of air conditioners, wherein one air conditioner can be a constant speed air conditioner or a variable frequency air conditioner, and the plurality of air conditioners can be all constant speed air conditioners or all variable frequency air conditioners, or can be both the constant speed air conditioner and the variable frequency air conditioner.
After receiving the air conditioner working instruction sent by the mobile terminal, the controller sends a corresponding air conditioner working scheme to the air conditioner, and after receiving the air conditioner working scheme, the corresponding air conditioner executes the air conditioner working scheme, namely, the corresponding air conditioner external unit is started, and the air conditioner works. When the air conditioner executes the working scheme of the air conditioner, the controller acquires the household electricity real-time current detected by the total current detection module when the air conditioner works from the total current detection module.
In this embodiment, the controller is preset with a safety threshold for the total current of the household power. It will be appreciated that the safety threshold for the total domestic current should be slightly less than the rated current of the domestic circuit breaker.
After the controller obtains the real-time current of the air conditioner during working, the real-time current is compared with a safety threshold value of the preset household electricity total current to obtain a comparison result, and then the working air conditioner is correspondingly controlled according to the comparison result and the type of the working air conditioner.
Specifically, step S20 is followed by:
step S21, if the real-time current does not exceed the preset total power utilization current safety threshold, no operation is executed;
after the controller compares the real-time current of the air conditioner executing the working scheme with the safety threshold of the preset household electricity total current, if the real-time current does not exceed the safety threshold of the preset household electricity total current, the controller does not execute operation on the working air conditioner, namely, the air conditioner continues to work normally.
Further, referring to fig. 4, step S30 includes:
step S31, if the real-time current exceeds a preset total power utilization current safety threshold, determining the type of an air conditioner executing an air conditioner working scheme, wherein the type of the air conditioner comprises a constant speed air conditioner and a variable frequency air conditioner;
step S310, when the air conditioner executing the air conditioner working scheme is a variable frequency air conditioner, executing power reduction operation or executing closing operation;
and step S311, when the air conditioner executing the air conditioner working scheme is a constant speed air conditioner, executing closing operation.
After the controller compares the real-time current of the air conditioner executing the air conditioner working scheme with the safety threshold of the preset household electricity total current, if the real-time current exceeds the safety threshold of the preset household electricity total current, the controller further determines the type of the air conditioner executing the air conditioner working scheme, wherein the type of the air conditioner comprises a constant speed air conditioner and a variable frequency air conditioner. The rotating speed of the compressor is fixed, and the rotating speed of the compressor determines the output power of the air conditioner, namely the output power of the constant speed air conditioner is fixed; the inverter air conditioner applies an inverter compressor and a fuzzy control technology, and the rotating speed of the compressor is variable, namely the output power of the inverter air conditioner is variable.
When the controller determines that the air conditioner executing the air conditioner working scheme is the variable frequency air conditioner, the controller executes power reduction operation or closing operation on the working variable frequency air conditioner.
When the controller determines that the air conditioner executing the air conditioner working scheme is the constant speed air conditioner, the controller performs closing operation on the working constant speed air conditioner.
Referring to fig. 5, step S31 is followed by:
step S312, comparing the real-time current with a preset first safety factor and a preset second safety factor when the plurality of air conditioners execute the air conditioner working scheme, wherein the plurality of air conditioners comprise a fixed-speed air conditioner and a variable-frequency air conditioner, the second safety factor is larger than the first safety factor, and the first safety factor is larger than a preset total power consumption current safety threshold;
step S313, if the real-time current is smaller than a first safety factor, performing power reduction operation on the variable frequency air conditioner, and not performing operation on the constant speed air conditioner;
step S314, if the real-time current is greater than a first safety factor and less than a second safety factor, closing the constant-speed air conditioner, and not executing the operation of the variable-frequency air conditioner;
and step S315, if the real-time current is greater than a second safety factor, closing all the air conditioners.
In this embodiment, after comparing the real-time current of the air conditioner executing the corresponding air conditioner working scheme with the safety threshold of the preset total household power current, if the real-time current exceeds the safety threshold of the preset total household power current, it is determined that a plurality of air conditioners executing the air conditioner working scheme are provided, and when the plurality of air conditioners include a fixed-speed air conditioner and a variable-frequency air conditioner, the corresponding operation is further executed according to the range where the real-time current exceeds the safety threshold of the preset total household power current.
Specifically, the controller is preset with a first current safety factor and a second current safety factor, the second safety factor is specified to be larger than the first safety factor, and the first safety factor is larger than a safety threshold of the preset household total current. It will be appreciated that the second safety factor is not likely to be excessive and should not exceed the rated current of the household electrical breaker. And the controller compares the real-time current with a preset first safety factor and a preset second safety factor.
After the controller compares the real-time current with a preset first safety factor and a preset second safety factor, if the real-time current is smaller than the first safety factor, performing power reduction operation on the variable-frequency air conditioner, and not performing operation on the constant-speed air conditioner; if the real-time current is greater than the first safety factor and less than the second safety factor, closing the constant-speed air conditioner, and not executing the operation on the variable-frequency air conditioner; and if the real-time current is greater than a second safety factor, closing all the air conditioners.
In further implementations, the controller may configure the display module to display the currently operating air conditioner and the current total current in real time. The controller can also send corresponding feedback information to the mobile terminal after controlling the air conditioner to execute the operation of closing or reducing the power so as to prompt the user of the current working state of the air conditioner.
The controller of the embodiment controls the air conditioner in the air conditioning system, so that the current of the household power supply does not exceed the rated current of the household circuit breaker, and the power failure is prevented.
Further, referring to fig. 6, a second embodiment of the control method of an air conditioning system according to the present invention provides a control method of an air conditioning system, and based on the above embodiment, before the step of obtaining the real-time current of power consumption at the air conditioning setting location when the air conditioner executes the preset air conditioning working scheme, the method further includes:
step S40, receiving an air conditioner working instruction;
step S50, determining the type of the air conditioner in the air conditioner working scheme corresponding to the air conditioner working instruction according to the air conditioner working instruction;
step S60, when there are a plurality of air conditioners in the air conditioner working scheme, and the plurality of air conditioners include a fixed speed air conditioner and a variable frequency air conditioner, executing the following steps:
step A, sending a command of executing work of the constant speed air conditioner;
b, when the working time of the constant speed air conditioner reaches a preset time threshold, closing the constant speed air conditioner, and sending a command of the variable frequency air conditioner to execute the working;
and step C, when the working time of the variable frequency air conditioner reaches a preset time threshold, closing the variable frequency air conditioner, and executing the step A.
In this embodiment, the controller configures a corresponding operation required status bit and an operation status flag bit for each air conditioner in the air conditioning system in advance.
