As shown in fig. 1, fig. 1 is a schematic structural diagram of an air conditioning system according to an embodiment of the present invention.
In the example of fig. 1, the air conditioning system according to the embodiment of the present invention includes a master 100, a slave 200, and a slave power supply module 300. The number of the slaves 200 may be one or more according to the requirements of the refrigeration system. The master 100 and the slave 200 are respectively connected with the carrier communication bus 140, and the master 100 and the slave 200 adopt an RS485 power carrier communication scheme, so that the master 100 and the slave 200 can utilize the carrier communication bus 140 to perform information interaction, such as receiving and sending communication signals. The slave machine 200 is provided with a slave machine MCU210 and a slave machine power supply module 220, the slave machine power supply module 220 can acquire power supply through the carrier communication bus 140, and the slave machine MCU210 can be connected with the slave machine power supply module 220, so that the slave machine power supply module 220 can supply power to the slave machine MCU210 after acquiring power supply.
The slave power supply module 300 is provided with a slave power supply management module 320 and a slave power supply input 310, wherein the slave power supply management module 320 is connected to the slave power supply input 310, and the slave power supply management module 320 is connected to the carrier communication bus 140, so that the slave power supply input 310 can be externally connected with a power supply and power is supplied to the carrier communication bus 140 by the slave power supply management module 320. Therefore, the air conditioning system can supply power to the slave 200 or stop supplying power to the slave 200 by loading power to the carrier communication bus 140, and a switch power supply is not required to be separately provided for the slave 200, so that the cost and the occupied space are saved, and the air conditioning system is convenient to install and use.
Referring to fig. 2, fig. 2 is a schematic structural diagram of an air conditioning system according to another embodiment of the present invention.
It will be appreciated that the air conditioning system is further provided with a power box 400, wherein the power box 400 includes a first MCU410, the slave power module 300 is installed in the power box 400, and the first MCU410 is connected to the slave power management module 320, so that the first MCU410 can control the slave power management module 320 to supply power to the carrier communication bus 140. Therefore, the power box 400 is mounted on the carrier communication bus 140, and the air conditioning system can supply power to the carrier communication bus 140 through the power box 400, so that the slave 200 can work without being provided with a switching power supply, and the installation cost and the occupied space are reduced.
It may be appreciated that the power box 400 is further provided with a first communication interface 430 and a first capacitance module 420, the first MCU410 is connected to the carrier communication bus 140 through the first communication interface 430, and the first capacitance module 420 is further provided between the first communication interface 430 and the carrier communication bus 140. The first MCU410 adopts an RS485 power carrier scheme, the first MCU410 sends a communication signal through the first communication interface 430, and the first capacitor module 420 is coupled to the carrier communication bus 140, so that the communication signal may be coupled to a communication channel in the carrier communication bus 140 through the first capacitor module 420, and the first MCU410 may also obtain, through the first communication interface 430 and the first capacitor module 420, a communication signal sent by another device from the carrier communication bus 140. In addition, the first capacitor module 420 can filter the dc signal from the carrier communication bus 140 to avoid interference with the operation of the slave power module 300 controlled by the first MCU410, resulting in unstable power supply.
The host 100 is further provided with a host MCU110, a host communication interface 130 and a second capacitor module 120, wherein the host MCU110 is connected to one end of the host communication interface 130, the other end of the host communication interface 130 is connected to one end of the second capacitor module 120, and the other end of the second capacitor module 120 is connected to the carrier communication bus 140. The communication signal sent by the host MCU110 passes through the host communication interface 130 and is coupled to the carrier communication bus 140 by the second capacitor module 120, and in addition, the host MCU110 may also obtain the communication signal from the slave 200 or the slave power module 300 from the carrier communication bus 140. Accordingly, the host MCU110 may transmit a control signal to the first MCU410 through the carrier communication bus 140, and the first MCU410 may acquire the control signal transmitted from the host MCU110 through the carrier communication bus 140, thereby controlling the slave power management module 320 to supply power or stop power through the carrier communication bus 140.
It should be noted that, since the number of the slaves 200 accessing the carrier communication bus 140 is greater, or the length of the carrier communication bus 140 is longer, the required power supply voltage is greater, in a case where long-distance power supply is required, for example, the distance between the master 100 and the slaves 200 is greater than 50 meters, or the number of the slaves 200 is greater, in order to improve the power supply security, the slave power supply module 300 is disposed in the power box 400, and the power box 400 and the master 100 are disposed independently, where the master 100 is further provided with a master power supply input end, and the master power supply input end may be connected to the slave power supply input end 310, or may not be connected to the slave power supply input end 310, that is, the power supply connected to the master power supply input end may be different from the power supply connected to the slave power supply input end 310, that is, the master MCU110 and the power box 400 independently supply power. Therefore, the power box 400 can supply power to the carrier communication bus 140 according to the communication signal of the host 100, so that the slave 200 can obtain power from the carrier communication bus 140, thereby avoiding the influence of a larger power supply voltage on the normal operation of the host 100, improving the safety, and reducing the design pressure.
Referring to fig. 3, fig. 3 is a schematic structural diagram of an air conditioning system according to another embodiment of the present invention.

It will be appreciated by those skilled in the art that the configuration of the air conditioning system illustrated in fig. 1, 2 and 3 is not limiting of the embodiments of the present invention and may include more or fewer components than illustrated, or may combine certain components, or a different arrangement of components.
Based on the structure of the air conditioning system described above, various embodiments of the control method of the air conditioning system of the present invention are presented.
As shown in fig. 4, fig. 4 is a flowchart of a control method of an air conditioning system according to an embodiment of the present invention, and the control method of an air conditioning system may be applied to the air conditioning system shown in fig. 2, where the control method of an air conditioning system includes, but is not limited to, the following steps:
step S100, a control signal from a host MCU is obtained through a first communication interface;
It is understood that the air conditioning system comprises a power box, wherein a first MCU is further arranged in the power box, and the first MCU is connected with a slave power management module in the slave power supply module. In addition, the host MCU in the host is connected with the second capacitor module through the host communication interface, and the second capacitor module is coupled with the carrier communication bus, so that the host MCU can send communication signals to the carrier communication bus through the host communication interface and the second capacitor module. The first MCU is connected with the first communication interface, and the first communication interface is connected with the carrier communication bus through the first capacitance module, so that the first MCU can acquire communication signals from the carrier communication bus through the first communication interface and the first capacitance module, and information interaction between the first MCU and the host MCU through the carrier communication signals is realized.
The slave power management module is respectively connected with the slave power input end and the carrier communication bus, so that the slave power management module can acquire power through the slave power input end and provide the power voltage to the carrier communication bus after processing the power voltage. The slave receives power from the carrier communication bus through the slave power module and supplies power to the slave MCU, so that the slave can work under the control of the slave MCU.
The first MCU obtains a control signal sent by the host MCU from the carrier communication bus through the first communication interface and the first capacitor module. The first MCU in the power box is connected with the slave power management module and controls the working state of the slave power management module according to the control signal. Because the control signals are different, the first MCU controls the slave power supply management module to enter the working state, and the first MCU can control the slave power supply management module to enter the working state, so that the slave power supply management module converts the input power supply of the input power supply into a proper output voltage and supplies power to the carrier communication bus through the first inductance module. The first MCU may also control the slave power management module to enter a stopped state such that the slave power management module stops operating, thereby stopping providing power to the carrier communication bus. Therefore, the air conditioning system controls the slave power management module through the first MCU in the power box, and can supply power to the carrier communication bus or stop supplying power, so that the slave also correspondingly enters a power-on state or a power-off state, the slave without a switching power supply is supplied with power through the power box, the switching power supply is not required to be equipped for the slave, the cost is reduced, and the occupied space is reduced.
It is understood that the control signal sent by the host MCU may be a power supply signal or a power stop signal. When the first MCU receives the power supply signal, the first MCU controls the slave power supply management module to enter a working state, so that the slave power supply management module converts the received voltage of the input power supply into a proper output voltage and applies the proper output voltage to the carrier communication bus to supply power for the carrier communication bus, and the slave can acquire power from the carrier communication bus through the slave power supply module to supply power for the slave MCU and a rear-stage load. When the first MCU receives the power stop signal, the first MCU controls the slave power management module to enter a stop state, so that the slave power management module stops working and does not perform voltage conversion and power supply to the carrier communication bus, and therefore, the carrier communication bus lacks power, and the slave cannot acquire power through the carrier communication bus and enters a power-off state to stop working. According to different control signals sent by the host MCU, the slave power management module is controlled to supply power to the carrier communication bus or stop supplying power, so that the slave is controlled to be electrified or powered off, and the function of the switch power supply of the slave is realized.
