Technical Field
The invention relates to the field of electrical equipment, in particular to an electrical equipment controller, a driving method thereof and electrical equipment.
Background
With the popularization of energy-saving consciousness in modern society, consumers pay more and more attention to the power consumption problem of electric equipment when purchasing the electric equipment. The air conditioner is an indispensable household appliance in modern families, and the power consumption of the air conditioner becomes an important index selected by consumers. The power consumption of the air conditioner mainly comprises the power consumption in the running state and the power consumption in the standby state, and consumers pay attention to the power consumption in the running state of the air conditioner on one hand and the standby power consumption of the air conditioner on the other hand, after all, the cost generated by the standby power consumption is not small and worth.
The standby state power consumption of only part of air conditioners in the existing consumer market can reach within 1W. A common standby low power consumption control scheme is based on the working principle that after an indoor controller receives a standby command, a Micro Control Unit (MCU) processor sends a control instruction to a control circuit of an outdoor unit power supply circuit to power off the outdoor unit (usually, a power relay is controlled to power off the outdoor unit controller). Because the air conditioner only has the switch power supply, the MCU, partial functional circuits and the remote control receiving circuit of the indoor unit controller to work in the standby state, the power consumption of the air conditioner is lower in the standby state. However, in the current standby state, the switching power supply and the MCU need to be in working states all the time, which causes the air conditioner to generate a certain power consumption even though it is in the standby state, and it is difficult to further reduce the power consumption. And the requirements of different air conditioners on the switching power supply in the current market are different, and the power switches of different air conditioners cannot be used universally, so that the power consumption of different air conditioners in the standby state is difficult to unify, and the difficulty of reducing the power consumption of the air conditioners in the standby state is further increased.

Most of the existing electrical equipment controllers adopt a switching power supply to supply power to each circuit device in the electrical equipment controller, and even if the electrical equipment is in a standby state, a remote control receiving module and an MCU of the electrical equipment must work constantly so as to receive a control instruction sent by the remote control equipment in time.
Fig. 1 is a schematic structural diagram of a conventional electrical equipment controller, which includes: a power supply module 101, a switching power supply 102, an MCU103, a remote control receiving module 104 and an outdoor unit control module 105. In the existing electrical equipment controller, the switching power supply 102 supplies power to the MCU103 and the remote control receiving module 104, and when the electrical equipment is in a standby state and a power-on state, the power supply mode is not changed, and the switching power supply 102 continuously supplies power to the MCU103 and the remote control receiving module 104, so that after the remote control receiving module 104 receives a control instruction sent by the remote control equipment, the MCU103 can perform corresponding response operation according to the control instruction. Therefore, even when the electrical equipment is in a standby state, the MCU103 and the remote control receiving module 104 generate power consumption, which affects the energy saving requirement of the electrical equipment. Therefore, the power consumption of the existing electrical equipment is still high in the standby state, and the requirements of the current consumers on the low-power-consumption electrical equipment cannot be met.
In view of the above problems, embodiments of the present invention provide an electrical device controller to meet the requirement of a consumer on low power consumption of an electrical device in a standby state.
The following embodiments of the present invention provide an electrical equipment controller for controlling standby power consumption of an air conditioner, and specifically describe a principle of controlling standby power consumption of an air conditioner by the electrical equipment controller according to the embodiments of the present invention.
As shown in fig. 2, an electrical device controller according to an embodiment of the present invention includes a remote control receiving module 201, an MCU202, a power switch conversion control module 203, a power switch conversion module 204, a power module 205, an auxiliary power supply 206, and a switching power supply 207.
Compared with the existing electrical equipment controller, the electrical equipment controller provided by the embodiment of the invention is additionally provided with a power switch conversion control module 203, a power switch conversion module 204 and an auxiliary power supply 206. The power switch conversion control module 203 is connected with the remote control receiving module 201 and the MCU202, the power switch conversion module 204 is connected with the power switch conversion control module 203, the power module 205 and the switching power supply 207, and the auxiliary power supply 206 is connected with the remote control receiving module 201 and the power switch conversion module 204.
In actual work, the electrical equipment controller provided by the embodiment of the invention has two different work flows in a standby state and a starting state.
Illustratively, when the air conditioner is in a power-on state, each module of the electrical equipment controller provided by the embodiment of the present invention has the following functions:
the remote control receiving module 201 is used for receiving a standby instruction sent by the remote control device and sending the standby instruction to the MCU 202;
the MCU202 is configured to receive a standby instruction sent by the remote control receiving module 201, generate a first control signal according to the standby instruction, and send the first control signal to the power switch conversion control module 203. Wherein, the first control signal is obtained when the MCU202 forwards the standby instruction;
the power switch conversion control module 203 is configured to amplify the first control signal after receiving the first control signal sent by the MCU202, and send the amplified first control signal to the power switch conversion module 204;
the power switch conversion module 204 is further configured to control the power module 205 and the auxiliary power supply 206 to be conducted and the power module 205 and the switching power supply 207 to be not conducted according to a first control signal sent by the power switch conversion control module 203;
and the auxiliary power supply 206 is used for supplying power to the remote control receiving module 201 and the power switch conversion module 204 after the power switch conversion module 204 controls the power supply module 205 and the auxiliary power supply 206 to be conducted.
At this time, the air conditioner is turned off and is changed from the on state to the standby state.
As can be seen from the above discussion, when the air conditioner is in the on state, the switching power supply 207 supplies power to the electrical equipment controller, and at this time, the electrical equipment controller at least includes the remote control receiving module 201 and the MCU202, which are in the operating state. After the electrical equipment controller receives a standby instruction sent by the remote control equipment, the switching between the switching power supply 207 and the auxiliary power supply 206 is realized through the power switch conversion control module 203 and the power switch conversion module 204, and the auxiliary power supply 206 starts to supply power to the electrical equipment controller. At this time, the auxiliary power supply 206 supplies power to the remote control receiving module 201 and the power switch converting module 204 in the electric appliance controller. However, since the power switch conversion module 204 only generates power consumption when the power supply is switched, only the remote control receiving module 201 is in a working state in practice, so that the remote control receiving module 201 can receive the control command sent by the remote control device in time. Therefore, compared with the prior art, the electrical equipment controller provided by the embodiment of the invention can reduce the power consumption of the air conditioner in the standby state.
Illustratively, when the air conditioner is in a standby state, each module of the electrical equipment controller provided by the embodiment of the invention has the following functions:
a remote control receiving module 201, configured to receive a power-on instruction sent by a remote control device, and send the power-on instruction to the power switch conversion control module 203;
the power switch conversion control module 203 is configured to receive the power-on instruction sent by the remote control receiving module 201, and send a second control signal to the power switch conversion module 204 after generating the second control signal according to the power-on instruction. The second control signal is obtained by amplifying the startup instruction by the power switch conversion control module 203;
the power switch conversion module 204 is configured to control the power module 205 and the switching power supply 207 to be conducted and the power module 205 and the auxiliary power supply 206 not to be conducted according to a second control signal sent by the power switch conversion control module 203;
and the switching power supply 207 is used for supplying power to the remote control receiving module 201 and the power switch conversion module 204 after the power switch conversion module 204 controls the power supply module 205 and the switching power supply 207 to be conducted.
At this time, the air conditioner is turned on and is changed from the standby state to the on state.
As can be seen from the above discussion, when the air conditioner is in the standby state, the auxiliary power supply 206 actually supplies power to the electrical equipment controller, after the remote control receiving module 201 receives the power-on instruction, the switching between the auxiliary power supply 206 and the switching power supply 207 is realized through the power switch conversion control module 203 and the power switch conversion module 204, and the switching power supply 207 starts to supply power to the electrical equipment controller, so that the electrical equipment enters the normal operating state.
Optionally, the starting instruction and the standby instruction in the embodiment of the present invention are both control instructions sent by the remote control device, and are used to instruct the air conditioner to perform corresponding functional operations. However, when the air conditioner is in the on state, the air conditioner can receive not only the standby instruction, but also the temperature adjustment instruction, the mode conversion instruction and the like. The standby instruction, the temperature adjusting instruction and the mode conversion instruction are all a working instruction received by the air conditioner in a starting state and are used for indicating the air conditioner to execute corresponding functional operation.
In the embodiment of the present invention, the control instructions sent by the remote control device are all pulse signals, as shown in fig. 3, which is a signal schematic diagram of a control instruction received by the remote control receiving module of the electrical device controller provided in the embodiment of the present invention, in order to ensure that the remote control receiving module has sufficient time to process different instructions so that the corresponding electrical device can normally operate, a certain delay exists between the start instruction and the standby instruction so that the air conditioner can receive other working instructions, such as the standby instruction, after the air conditioner is started.
Optionally, as shown in fig. 4, the power switch conversion control module 203 provided in the embodiment of the present invention includes a first power switch conversion control sub-module 2031 and a second power switch conversion control sub-module 2032;
the first power switch conversion control sub-module 2031 is configured to receive a power-on instruction sent by the remote control receiving module 201, and send a second control signal to the power switch conversion module 204 after generating the second control signal according to the power-on instruction;
the second power switch conversion control sub-module 2032 is configured to receive the first control signal sent by the MCU202, and send the first control signal to the power switch conversion module 204.
Optionally, as shown in fig. 4, because the air conditioner further includes an outdoor unit control module 208, the electrical equipment controller according to the embodiment of the present invention is further configured to control the outdoor unit to stop operating in the on state. Specifically, after the MCU202 receives the standby instruction sent by the remote control receiving module 201, the MCU202 sends a first control signal to the outdoor unit control module 208, and the outdoor unit control module 208 controls the switching power supply 207 to cut off power from the outdoor unit, so that the outdoor unit stops working.
Further, the first power switch conversion control sub-module 2031 is further configured to amplify the standby instruction to obtain a second control signal;
the second power switch conversion control sub-module 2032 is further configured to amplify the first control signal sent by the MCU 202.
Referring to fig. 4, the switching power supply 207 includes a switching power supply main interface 2071, a switching power supply first interface 2072, a switching power supply second interface 2073, a switching power supply third interface 2074 and a switching power supply fourth interface 2075;
the switching power supply 207 receives the operating voltage provided by the power module 205 through the switching power supply main interface 2071, supplies power to the remote control receiving module 201 through the switching power supply first interface 2072, supplies power to the MCU202 through the switching power supply second interface 2073, supplies power to the outdoor unit control module 208 through the switching power supply third interface 2074, and supplies power to the power switch conversion module 204 through the switching power supply fourth interface 2075.
Specifically, according to the functional description of the electrical equipment controller, as shown in fig. 5, an embodiment of the present invention provides a circuit structure schematic diagram of an electrical equipment controller, which is specifically described as follows:
the first power switch conversion control submodule comprises a first resistor R1, a second resistor R2 and a first triode A1.
