Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0046] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0047] 1. In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present application.

[0048] 2. In the description of this application, “plurality” means two or more.

[0049] The present application provides a control system for a refrigeration device.

[0050] like Figure 1 As shown, the control system of the refrigeration equipment includes: a main control device 110 and at least one sub-control device 120.

[0051] It should be noted that the refrigeration equipment in this embodiment can be understood as refrigeration storage equipment in a broad sense, including but not limited to refrigerators, freezers, display cabinets, beverage cabinets, wine cabinets, fresh-keeping cabinets, refrigerated vending machines and other refrigeration storage equipment. The storage equipment has various structural forms and a wide range of applications.

[0052] In this embodiment, the control system of the refrigeration equipment is used to control the operation of the refrigeration equipment.

[0053] For example, the control system may control the operating state of the refrigeration equipment, or may control the operating state of the load within the refrigeration equipment.

[0054] The main control device 110 can be arranged at any part of the refrigeration equipment, such as Figure 1 As shown, the main control device 110 can be arranged on the top of the refrigeration equipment, or can also be arranged in the middle of the refrigeration equipment, etc.

[0055] The main control device 110 may be a PCB board.

[0056] At least one air duct may be provided in the refrigeration device.

[0057] By setting up air ducts, cold air and hot air can flow between different areas, thereby controlling the temperature of different compartments inside the refrigeration equipment.

[0058] At least one sub-control device 120 is arranged in a one-to-one correspondence with at least one air duct included in the refrigeration equipment.

[0059] In some embodiments, the sub-control device 120 may include a PCB board.

[0060] The number of at least one sub-control device 120 may be one or more. For example, the number of at least one sub-control device 120 may be 2 or 3. This may be set based on user needs and is not limited in this application.

[0061] The sub-control device 120 may be disposed in the air duct.

[0062] For example, when a refrigeration air duct is provided in the refrigeration equipment, a sub-control device 120 may be provided in the refrigeration air duct.

[0063] In the case where a refrigerating air duct and a freezing air duct are provided in the refrigerating equipment, a sub-control device 120 may be provided in each of the refrigerating air duct and the freezing air duct, respectively.

[0064] like Figure 2 and Figure 3 As shown, when the sub-control device 120 is set in the refrigeration air duct, the sub-control device 120 may include a refrigeration air duct plate; when the sub-control device 120 is set in the freezing air duct, the sub-control device 120 may include a freezing air duct plate.

[0065] Each sub-control device 120 is connected to the main control device 110 via a target communication bus.

[0066] The target communication bus includes at least one cable. The number of the at least one cable can be 2, 3 or 4, or can be other values. It can be based on user customization and is not limited in this application.

[0067] The communication protocol of the target communication bus may include a serial communication protocol, a full-duplex communication protocol, an asynchronous serial communication protocol, or the like.

[0068] When the target communication buses are different, the communication methods between the sub-control device 120 and the main control device 110 are also different.

[0069] At least one load is arranged in the refrigeration device.

[0070] The inventors discovered during the research and development process that in the related art, the main control device 110 is directly connected to each load to control the operation of each load, which results in the cables being too long and the wire harness at the outlet of the embedded box being thick.

[0071] The sub-control device 120 is used to be connected to at least one load via a first line.

[0072] The number of cables included in the first line may be set based on the load type.

[0073] For example, when the load is a wind turbine, the number of cables included in the first line may be 4; when the load is a sensor, the number of cables included in the first line may be 2.

[0074] The sub-control device 120 to which the load is connected may be determined based on the distance between the load and each sub-control device 120 . For example, when the load is closer to a first sub-control device 120 among at least one sub-control device 120 , the load may be connected to the first sub-control device 120 .

[0075] Alternatively, the sub-control device 120 to which the load is connected may be determined based on the type of load. For example, when at least one sub-control device 120 is respectively arranged in the refrigeration duct and the freezing air duct, when the load is a refrigeration fan 150, the refrigeration fan 150 may be arranged to be connected to the sub-control device 120 arranged in the refrigeration duct; when the load is a freezing fan 200, the freezing fan 200 may be arranged to be connected to the sub-control device 120 arranged in the freezing air duct.

[0083] One end of the data bus is connected to the main control device 110 , and the other end of the data bus is connected to at least one sub-control device 120 .

[0084] For example, the main control device 110 may be provided with a BUS line port, through which a data bus may be connected.

[0085] The data bus may include a parallel bus or a serial bus. When the data bus is a parallel bus, multiple bits can be transmitted simultaneously, but more physical wires are required; when the data bus is a serial bus, data can be transmitted bit by bit, and fewer wires are required for communication.

[0090] The voltage value provided by the first power line can be based on user customization, such as Figure 2 As shown, it can be 12V.

[0091] One end of the first power line is connected to the power output port of the main control device 110 , and the other end of the first power line is connected to the power input port of at least one sub-control device 120 .

[0092] According to the control system of the refrigeration equipment provided in the embodiment of the present application, three wires are used to perform BUS communication between the main control device 110 and the sub-control device 120, so that multi-point communication can be performed between the main control device 110 and the sub-control device 120, thereby enhancing the reliability of communication and reducing cable costs.

[0100] One end of the receiving line may be connected to a receiving port of the main control device 110 , and the other end of the receiving line may be connected to a transmitting port of at least one sub-control device 120 .

[0101] The second ground line (GND line) is used to provide a common reference potential to ensure the stability and accuracy of data transmission.

[0102] One end of the second ground wire may be connected to the main control device 110 . For example, one end of the second ground wire may be connected to a GND line port on the main control device 110 .

[0103] The other end of the second ground wire may be connected to at least one sub-control device 120 , for example, the other end of the second ground wire may be connected to a GND line port on the sub-control device 120 , respectively.

[0104] The second power line may be used to supply power to components within the sub-control device 120 .

[0105] The voltage value provided by the second power line can be based on user customization, such as Figure 3As shown, it can be 12V.

[0106] One end of the second power line can be connected to the power output port of the main control device 110, and the other end of the second power line can be connected to the power input port of at least one sub-control device 120 respectively.

[0107] According to the control system of the refrigeration equipment provided in the embodiment of the present application, serial communication is performed between the main control device 110 and the sub-control device 120 through four wires, which is suitable for short-distance point-to-point communication, improves communication speed and communication stability, and reduces costs.
