Detailed Description
Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
A method and apparatus for controlling a load and an air conditioner according to an embodiment of the present invention will be described with reference to fig. 1 to 3.
Fig. 1 is a flowchart of a method of controlling a load according to one embodiment of the present invention. Wherein the load is plural, that is, includes a plurality of loads.
As shown in fig. 1, the method for controlling the load includes the following steps:
step S1: and setting a preset time base.
Step S2: and controlling one of the plurality of loads to perform an opening or closing action in each preset time base.
Step S3: polling the plurality of loads, and sequentially controlling the plurality of loads to execute opening or closing actions according to a preset sequence until the plurality of loads all execute the opening or closing actions.
In a particular embodiment, the preset time base is configured to be, for example, 100 milliseconds. That is, in a preset time base of 100 milliseconds, the on or off actions are polled for each load, thereby ensuring that each preset time base only controls a single load to output.
Therefore, the load control method sets the preset time bases, controls one of the plurality of loads to execute the opening or closing action in each preset time base, polls the plurality of loads, and sequentially controls the plurality of loads to execute the opening or closing action according to the preset sequence until the plurality of loads all execute the opening or closing action. Namely, the method controls the load action by adopting a time-based polling control mode, can effectively reduce the impact and pollution to the power grid when the load of household electrical appliances and the like acts, realizes the purposes of energy conservation and emission reduction, and can effectively prolong the service life of household electrical appliances.
In one embodiment of the present invention, in step S3, the plurality of loads are polled, and the plurality of loads are sequentially controlled to perform the opening or closing actions according to a preset sequence until the plurality of loads all perform the opening or closing actions. In a specific embodiment, for example, a plurality of loads are numbered, and are denoted as load 1, load 2.. and load N, and an order of performing the turning-on or turning-off operations of the plurality of loads is preset, for example, according to load 1, load 2.. and load N sequentially performs the turning-on or turning-off operations. Wherein only one load performs an on or off action in each preset time base.
In an embodiment of the present invention, a process of sequentially controlling a plurality of loads to perform an opening or closing action according to a preset sequence specifically includes: setting a pointer variable; and sequentially controlling a plurality of loads to execute opening or closing actions according to the guidance of the pointer variable in a plurality of preset time bases according to a preset sequence. Specifically, according to the guidance of the pointer variable, in each preset time base, according to the preset sequence, the corresponding load in the plurality of loads is sequentially controlled to execute the opening or closing action.
In an embodiment of the present invention, a process of sequentially controlling a plurality of loads to execute an opening or closing action according to a preset sequence in a plurality of preset time bases according to a direction of a pointer variable specifically includes: when each preset time base arrives, the pointer variable is controlled to be added with 1, and the load which is currently pointed by the pointer variable is controlled to execute opening or closing action; and controlling the pointer variable to reset and clear until the plurality of loads correspondingly and sequentially execute the opening or closing action, and entering the next polling process.
In the embodiment, the preset time base is 100 milliseconds for example. That is, when each load polls the action, a pointer variable is designed, and the pointer variable is used to direct each load to execute the corresponding action according to the preset sequence in the preset time base. When the load polls, the pointer variable is increased once every 100 milliseconds (namely a preset time base), and after all the loads are polled once, the pointer variable is reset and cleared, so that the next repeated action is carried out, namely the next polling process is started. Therefore, the driving of only one load can be executed in every 100 milliseconds (namely one preset time base), so that the problems that a plurality of loads act simultaneously to cause noise pollution to a power grid, harmonic waves increase, circuit loss increases, energy efficiency is reduced and the like can be avoided, the impact and pollution to the power grid caused by the action of the loads of household electrical appliances and the like can be effectively reduced, the purposes of energy conservation and emission reduction are achieved, and meanwhile, the service life of household electrical appliances can be effectively prolonged.
More specifically, the process of each load executing actions is described in detail as follows: when the main program of the single chip microcomputer runs, a pointer operation unit is called every 100 milliseconds (namely a preset time base) to automatically add 1 to a pointer variable, when the pointer variable points to a corresponding load driving module, the starting or closing action of a corresponding load is executed (the starting or closing control of the load is realized in a load starting and stopping logic operation subprogram, which is not described herein in detail), after the load execution action is finished, the load control subprogram is exited, and the main program is re-entered. When the main program runs to the next 100 milliseconds (namely the next preset time base), other loads are correspondingly controlled to execute corresponding actions in sequence until all the loads execute the actions once, the pointer variable is reset and cleared, and the load control is executed by polling again.
In one embodiment of the present invention, a plurality of loads are controlled by a plurality of relays, and the method for controlling the loads further includes the steps of: and controlling one action of the plurality of relays in each preset time base so as to correspondingly enable one of the plurality of loads to execute an opening or closing action.
Specifically, each load is controlled by one relay, and the on/off of the load is controlled by the on/off of the relay. It can be understood that the power grid sudden change possibly caused by the simultaneous action of a plurality of relays also possibly causes the adhesion of relay contacts, thereby reducing the service life of the relays. Based on this, the embodiment of the invention controls one action of the plurality of relays in each preset time base (such as 100 milliseconds) so as to correspondingly enable one of the plurality of loads to execute the opening or closing action, thereby preventing the sudden change of the power grid and the adhesion of the relay contact and prolonging the service life of the relay. Namely, a time base polling relay control mode is adopted, the relay is ensured to be controlled according to a preset time base (such as 100 milliseconds), and only one relay is controlled to act in each preset time base, so that the problems of power grid sudden change and relay contact adhesion caused by simultaneous actions of the relays are avoided, and the service life of the relay is prolonged.
As a specific example, a detailed exemplary description is given below of the control method of the load with reference to fig. 2.
In the specific embodiment, an outdoor unit of a household air conditioner is taken as an example, and the control method for reducing the load of the power grid input noise according to the embodiment of the invention is described in detail. Referring to fig. 2, the outdoor unit of the household air conditioner includes, for example, 5 loads, i.e., a compressor, an outdoor fan, a four-way valve, a chassis electric heater, and a refrigerant heat dissipation valve. It is assumed that the on or off control logic of each load has been set and processed in the whole control system, and only the description of the timing control of the output driving end of the load is given here. In the control system of the outdoor unit, 100 milliseconds are preset as a preset time base, corresponding loads are output in the preset time base through polling control, each preset time base only controls the action of a single load, and only the opening or closing of the single load is controlled independently, so that the polling control is sequentially performed on a plurality of loads in a plurality of preset time bases, and the noise pollution caused by the impact on a power grid due to the simultaneous output of the plurality of loads is avoided.
In the specific embodiment, as shown in fig. 2, in the process of executing the load control method, 5 loads are set, that is, the operation sequence of the compressor, the outdoor fan, the four-way valve, the chassis electric heating and the refrigerant heat dissipation valve, that is, the preset sequence is the compressor, the outdoor fan, the four-way valve, the chassis electric heating and the refrigerant heat dissipation valve in sequence. After pointer operation is started, judging whether pointer polling is compressor action, if so, controlling the compressor action, otherwise, further judging whether the pointer polling is fan action, if so, controlling the fan action, otherwise, further judging whether the pointer polling is four-way valve action, if so, controlling the four-way valve action, otherwise, further judging whether the pointer polling is chassis electric heating action, if so, executing the chassis electric heating action, otherwise, further judging whether the pointer polling is refrigerant heat dissipation valve action, if so, controlling the refrigerant heat dissipation valve action, and otherwise, ending the flow. Therefore, 5 loads are polled, so that only one load is controlled to execute corresponding actions in each preset time base according to the preset sequence, and the next polling process is started after 5 loads in the 5 preset time bases are controlled to execute the corresponding actions. Therefore, the load action of the air conditioner outdoor unit is controlled in a time-based polling control mode, the impact and pollution to a power grid caused by the load action of the air conditioner outdoor unit can be effectively reduced, the purposes of energy conservation and emission reduction are achieved, and meanwhile, the service life of the air conditioner outdoor unit can be effectively prolonged.
In this embodiment, when polling each load of the outdoor unit of the household air conditioner, a pointer variable is designed, and the pointer variable is used to direct each load to execute the actions according to a preset sequence in a preset time base. The load polling pointer is increased once every 100 milliseconds, after all the loads are polled once, the pointer resetting and clearing operation is executed, so that the next repeated action is carried out, the driving of only one load can be executed in every 100 milliseconds time base, and the grid noise caused by simultaneous actions of multiple loads can be reduced.
Specifically, the load execution process is described in detail as that when the main program runs, the time base arrives every 100 milliseconds, the pointer operation unit is called, the pointer is automatically added by 1, when the pointer variable points to the corresponding load driving module, the start and stop actions of the corresponding load are executed, the load execution is finished, the load control subprogram is exited, and the main program is re-entered. And when the main program runs to the next 100-millisecond time base, executing corresponding other loads until all the loads are executed once, resetting and clearing the pointer, and polling again to execute load control.
According to the load control method, the preset time bases are set, one of the plurality of loads is controlled to execute opening or closing actions in each preset time base, the plurality of loads are polled, and the plurality of loads are sequentially controlled to execute the opening or closing actions according to the preset sequence until the plurality of loads all execute the opening or closing actions. Therefore, the method controls the load action by adopting a time-based polling control mode, can effectively reduce the impact and pollution to the power grid when the load of household electrical appliances and the like acts, realizes the purposes of energy conservation and emission reduction, and can effectively prolong the service life of household electrical appliances.
A further embodiment of the present invention provides a control apparatus for a load.
Fig. 3 is a schematic configuration diagram of a control apparatus of a load according to an embodiment of the present invention. Wherein, the load is a plurality of, that is, comprises a plurality of loads.
As shown in fig. 3, the load control device 100 includes: a timing module 110 and a control module 120.
The timing module 110 is configured to set a preset time base.
The control module 120 is configured to control one of the plurality of loads to perform an opening or closing action in each preset time base, poll the plurality of loads, and sequentially control the plurality of loads to perform the opening or closing action according to a preset sequence until the plurality of loads all perform the opening or closing action.
In a particular embodiment, the preset time base is configured to be, for example, 100 milliseconds. That is, in a preset time base of 100 milliseconds, the on or off actions are polled for each load, thereby ensuring that each preset time base only controls a single load to output.
Accordingly, the control apparatus 100 for the load sets the preset time bases, controls one of the plurality of loads to perform the opening or closing operation in each of the preset time bases, polls the plurality of loads, and sequentially controls the plurality of loads to perform the opening or closing operation in accordance with the preset sequence until the plurality of loads each perform the opening or closing operation. Namely, the device 100 controls the load action by adopting a time-based polling control mode, so that the impact and pollution to the power grid caused by the load action of household electrical appliances and the like can be effectively reduced, the purposes of energy conservation and emission reduction are achieved, and meanwhile, the service life of household electrical appliances can be effectively prolonged.
In an embodiment of the present invention, the control module 120 polls the plurality of loads and sequentially controls the plurality of loads to perform the opening or closing action according to a preset sequence until all the plurality of loads perform the opening or closing action. In a specific embodiment, for example, a plurality of loads are numbered, and are denoted as load 1, load 2.. and load N, and an order of performing the turning-on or turning-off operations of the plurality of loads is preset, for example, according to load 1, load 2.. and load N sequentially performs the turning-on or turning-off operations. Wherein only one load performs an on or off action in each preset time base.
In an embodiment of the present invention, the controlling module 120 sequentially controls the plurality of loads to perform the opening or closing process according to a preset sequence, which specifically includes: setting a pointer variable, and sequentially controlling a plurality of loads to execute opening or closing actions according to a preset sequence in a plurality of preset time bases according to the guidance of the pointer variable. Specifically, according to the guidance of the pointer variable, in each preset time base, according to the preset sequence, the corresponding load in the plurality of loads is sequentially controlled to execute the opening or closing action.
In an embodiment of the present invention, the controlling module 120 sequentially controls, according to the instruction of the pointer variable, the plurality of loads to execute the process of opening or closing actions according to the preset sequence in the plurality of preset time bases, specifically including: and when each preset time base arrives, adding 1 to the control pointer variable, controlling the load to which the control pointer variable points currently to execute opening or closing actions, resetting and clearing the control pointer variable until a plurality of loads correspondingly and sequentially execute the opening or closing actions, and entering the next polling process.
In the embodiment, the preset time base is 100 milliseconds for example. That is, when each load polls the action, a pointer variable is designed, and the pointer variable is used to direct each load to execute the corresponding action according to the preset sequence in the preset time base. When the load polls, the pointer variable is increased once every 100 milliseconds (namely a preset time base), and after all the loads are polled once, the pointer variable is reset and cleared, so that the next repeated action is carried out, namely the next polling process is started. Therefore, the driving of only one load can be executed in every 100 milliseconds (namely one preset time base), so that the problems that a plurality of loads act simultaneously to cause noise pollution to a power grid, harmonic waves increase, circuit loss increases, energy efficiency is reduced and the like can be avoided, the impact and pollution to the power grid caused by the action of the loads of household electrical appliances and the like can be effectively reduced, the purposes of energy conservation and emission reduction are achieved, and meanwhile, the service life of household electrical appliances can be effectively prolonged.
More specifically, the process of each load executing actions is described in detail as follows: when the main program (i.e., the control module 120) of the single chip microcomputer runs, the pointer operation unit is called once every 100 milliseconds (i.e., every preset time base) is up, the pointer variable is automatically increased by 1, when the pointer variable points to the corresponding load driving module, the start or close action of the corresponding load is executed (the start or close control of the load is realized in the load start and stop logic operation subprogram, which is not described herein), when the load execution action is finished, the load control subprogram is exited, and the main program (i.e., the control module 120) is re-entered. When the main program runs to the next 100 milliseconds (namely the next preset time base), other loads are correspondingly controlled to execute corresponding actions in sequence until all the loads execute the actions once, the pointer variable is reset and cleared, and the load control is executed by polling again.
In an embodiment of the present invention, the plurality of loads are controlled by a plurality of relays, and the control module 120 is further configured to: and controlling one action of the plurality of relays in each preset time base so as to correspondingly enable one of the plurality of loads to execute an opening or closing action.
Specifically, each load is controlled by one relay, and the on/off of the load is controlled by the on/off of the relay. It can be understood that the power grid sudden change possibly caused by the simultaneous action of a plurality of relays also possibly causes the adhesion of relay contacts, thereby reducing the service life of the relays. Based on this, the embodiment of the invention controls one action of the plurality of relays in each preset time base (such as 100 milliseconds) so as to correspondingly enable one of the plurality of loads to execute the opening or closing action, thereby preventing the sudden change of the power grid and the adhesion of the relay contact and prolonging the service life of the relay. Namely, a time base polling relay control mode is adopted, the relay is ensured to be controlled according to a preset time base (such as 100 milliseconds), and only one relay is controlled to act in each preset time base, so that the problems of power grid sudden change and relay contact adhesion caused by simultaneous actions of the relays are avoided, and the service life of the relay is prolonged.
The control device 100 for the load is described in detail with reference to specific embodiments.
In the specific embodiment, taking an outdoor unit of a household air conditioner as an example, the control device 100 for reducing a load of power grid input noise according to the embodiment of the present invention will be described in detail. Specifically, the outdoor unit of the household air conditioner includes, for example, 5 loads, i.e., a compressor, an outdoor fan, a four-way valve, a chassis electric heater, and a refrigerant heat dissipation valve. It is assumed that the on or off control logic of each load has been set and processed in the whole control system, and only the description of the timing control of the output driving end of the load is given here. In the control system of the outdoor unit, 100 milliseconds are preset as a preset time base, corresponding loads are output in the preset time base through polling control, each preset time base only controls the action of a single load, and only the opening or closing of the single load is controlled independently, so that the polling control is sequentially performed on a plurality of loads in a plurality of preset time bases, and the noise pollution caused by the impact on a power grid due to the simultaneous output of the plurality of loads is avoided.
In the embodiment, in the execution process of the load control device 100, 5 loads are set, that is, the operation sequence of the compressor, the outdoor fan, the four-way valve, the chassis electric heater, and the refrigerant heat dissipation valve, that is, the preset sequence is the compressor, the outdoor fan, the four-way valve, the chassis electric heater, and the refrigerant heat dissipation valve in sequence.
