[0051] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0052] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0053] The following, in conjunction with the accompanying drawings, describes in detail the control method for refrigeration equipment, the control device for refrigeration equipment, the electronic device, and the readable storage medium provided in the embodiments of the present application through specific embodiments and their application scenarios.

[0054] The control method for the refrigeration equipment may be applied to a terminal, and may be specifically executed by hardware or software in the terminal.

[0055] The terminal includes, but is not limited to, a portable communication device such as a mobile phone or tablet computer having a touch-sensitive surface (e.g., a touch screen display and / or a touch pad). It should also be understood that, in some embodiments, the terminal may not be a portable communication device, but a desktop computer having a touch-sensitive surface (e.g., a touch screen display and / or a touch pad).

[0056] In the following embodiments, a terminal including a display and a touch-sensitive surface is described. However, it should be understood that the terminal may include one or more other physical user interface devices such as a physical keyboard, a mouse, and a joystick.

[0057] The control method for a refrigeration device provided in an embodiment of the present application may be executed by a refrigeration device or an electronic device, or may be a functional module or functional entity in the refrigeration device or electronic device that can implement the control method for the refrigeration device. The electronic devices mentioned in the embodiment of the present application include but are not limited to mobile phones, tablet computers, computers, cameras, and wearable devices. The control method for a refrigeration device provided in an embodiment of the present application is described below using an electronic device as an example of the execution subject.

[0058] like Figure 1 As shown, the control method of the refrigeration equipment includes: step 110 and step 120.

[0059] It should be noted that the refrigeration equipment may include a wall-mounted air conditioner, a floor-standing air conditioner, a central air conditioner or a window air conditioner, etc.

[0060] The refrigeration equipment may include an outdoor main body, at least one branch box and a plurality of indoor main bodies.

[0061] Each branch box can be connected to an outdoor main body, and each branch box is connected to at least one indoor main body.

[0062] The outdoor main body may include a unit outdoor unit, a multi-split outdoor unit or a household split outdoor unit, etc., which can be determined based on the matching between the outdoor main body and the branch box, and this application does not limit it.

[0063] The indoor main body may include a wall-mounted unit, a ceiling unit, a duct unit, a cabinet unit, etc., which is not limited in this application.

[0064] Step 110: Generate a target communication address corresponding to each indoor entity connected to the target branch box based on the maximum connectable number of the target branch box in at least one branch box and the connection order of each indoor entity connected to the target branch box on the target branch box;

[0065] In this step, the target branch box is any one of the at least one branch box.

[0066] The maximum number of connections is the maximum number of indoor units that can be connected to the target branch box. The maximum number of connections can be determined based on information such as the design specifications of the branch box and the capacity of the outdoor units.

[0067] The branch box can include multiple communication interfaces (such as current loop communication interfaces), each of which can be connected to the indoor body. The target branch box can perform handshake communication with the indoor body through the communication interface, confirm whether the communication interface is connected to the indoor body, and mark the connection status of the communication interface that successfully handshakes.

[0068] For example, the target branch box can be set with 5 communication interfaces (the communication interfaces can be numbered 1, 2, 3, 4 and 5 respectively), and the maximum number of connections corresponding to the target branch box can be 5. The target branch box can confirm whether the communication interface is connected to an indoor entity through handshake communication. For example, when it is determined that interface No. 1, interface No. 2 and interface No. 5 are connected to indoor entities, interface No. 1, interface No. 2 and interface No. 5 can be marked as "connected successfully", and it can be determined that the connection order of the indoor entities connected to the target branch box on the target branch box is 1, 2 and 5.

[0069] The connection order can be any value between 1 and the maximum number of connections.

[0070] During the actual execution process, the target branch box can be powered on and initialized, and variables, chip IO (the chip's signal input and output interface circuit), AD interface (AD interface is an interface that converts analog signals into digital signals), timers and communication interfaces can be initialized.

[0071] For example, global variables can be initialized to provide an initial state for system operation. For example, variables used to store the internal machine connection status and communication status can be defined and initialized to default values.

[0072] Configure the chip's IO interface, including input and output modes, and level status.

[0073] The AD interface can be configured, including parameters such as reference voltage selection and sampling time.

[0074] Configure the timer's clock source, prescaler, and auto-reload parameters.

[0075] Initialize the communication interface, including the configuration of parameters such as baud rate, data bits and stop bits.

[0076] When the communication interface of the target branch box completes the initialization process, the protocol format of the handshake communication can be defined, including the structure of the request frame and the response frame.

[0077] The target branch box can perform handshake communication with the connected indoor main body interfaces one by one, and send a handshake request frame to each indoor main body through the communication interface. After sending the request, the target branch box waits for the response of the indoor main body. If the response is received within the specified time, it can be determined that the handshake is successful. If no response is received within the specified time, it can be determined that the interface is not connected to the indoor main body.

[0078] like Figure 3As shown, when the indoor subject N responds to the handshake request (that is, the current loop communication of the indoor subject N is normal, where N is the Nth communication interface in the target branch box), the target branch box can mark the interface N as "connected successfully", that is, the indoor subject N exists, and judge whether N is less than the maximum connectible number Nmax corresponding to the target branch box. When N is less than Nmax, the handshake communication with the indoor subject N+1 can continue through the N+1th communication interface. When the indoor subject N+1 does not respond to the handshake request (that is, the current loop communication of the indoor subject N+1 is abnormal), the target branch box can mark the interface N+1 as "not connected" or "connection failed", that is, the indoor subject N+1 does not exist, and then judge whether N+1 is less than Nmax. When N+1 is equal to Nmax, the existence of the indoor subjects corresponding to all interfaces of the target branch box can be determined.

[0079] If it is found in subsequent communications that the connection status of a certain interface has changed (such as from connected to unconnected), the target branch box can re-perform handshake communication to determine the status.

[0080] The target communication address corresponding to the indoor subject is a virtual address generated by the branch box. The branch box can generate a virtual address corresponding to each indoor subject based on the maximum connectable number and the connection order of the connected indoor subjects on the branch box.

[0081] For an indoor entity marked as "connected successfully", the target branch box can generate a target communication address corresponding to the indoor entity.

[0082] Step 120: The target branch box responds to the addressing request sent by the outdoor body and sends the target communication addresses corresponding to the indoor bodies connected to the target branch box to the outdoor body, so that the outdoor body establishes communication connections with the indoor bodies.

[0083] In this step, when the outdoor subject is started or initialized, it may broadcast an addressing request to all connected devices. The addressing request may include a specific indication code for querying all connected indoor subjects.

[0084] The branch box can monitor the addressing request sent by the outdoor entity through its communication interface. When an addressing request is received, the branch box can parse the request content and prepare a response.

[0085] The branch box can obtain the communication address of each connected indoor subject, and pack the communication addresses of all connected indoor units into a response data packet, and then send the response data packet to the outdoor subject.

[0086] After receiving the response data packet sent by the branch box, the outdoor subject can parse the data packet content, obtain the target communication address of each indoor subject, and establish a communication connection with each indoor subject.

[0087] According to the control method of the refrigeration equipment provided in the embodiment of the present application, a virtual communication address can be generated for each indoor subject through the maximum connectable number corresponding to the target branch box and the connection order of the connected indoor subjects on the target branch box, and then the target communication address of each indoor subject can be sent to the outdoor subject in response to the addressing request sent by the outdoor subject to establish a communication connection between the outdoor subject and the indoor subject, thereby realizing that one branch box can virtually communicate with multiple indoor subjects on the bus, and the branch box can automatically assign communication addresses to the indoor subjects, thereby improving the freedom and flexibility of matching the outdoor subject and the indoor subject, and can meet the needs of large-scale networking, thereby meeting the diverse configuration needs of the market, and realizing arbitrary cascading of multiple branch boxes, as well as free networking and dynamic communication address management between the branch box and the indoor subject, broadening the applicable scenarios.

[0088] In some embodiments, step 110 may include:

[0089] Determine the address coding interval corresponding to the target branch box based on the dial address corresponding to the target branch box and the maximum connectable number corresponding to the target branch box, or based on the random number generated by the target branch box and the maximum connectable number corresponding to the target branch box;

[0090] Based on the address code interval and the connection order of each indoor main body connected to the target branch box on the target branch box, a target communication address corresponding to each indoor main body connected to the target branch box is generated.

[0091] In this embodiment, a group of toggle switches may be provided on the branch box, each switch corresponds to a binary bit, and the address of the branch box may be set by the position of the toggle switch (on or off).

[0092] For example, when a 4-bit DIP switch is set, the maximum DIP address of the branch box can be 16. When the system is initialized, the branch box can read the status of the DIP switch, convert it into a binary number, and then convert it into a decimal address.

[0093] The address of the branch box can be dialed manually, and the dial address corresponding to each branch box is different.

[0094] A random number may be generated based on the values ​​of sensors or other components in the target branch box, or the target branch box may generate a random number when it is powered on, which is not limited in this application.

[0095] The address coding interval corresponding to the branch box is used to represent the span of address coding that the branch box can assign to the connected indoor entities. For example, the maximum number of connections corresponding to branch box 1 is 5, and the address coding interval corresponding to branch box 1 is 1 to 5. Branch box 1 is actually connected to three indoor entities, and the corresponding communication address can be assigned to each connected indoor entity within the 5 address coding intervals;

[0096] When a fourth indoor entity is newly added to the branch box 1 , a corresponding communication address can be allocated to the fourth indoor entity within the five address coding intervals.

[0097] The address coding interval corresponding to the next branch box of branch box 1 can be 6 to 10, which avoids conflicts in the communication addresses corresponding to the indoor entities in the two branch boxes.

[0098] A corresponding target communication address may be generated for each indoor entity based on the address coding interval and the connection order of each indoor entity connected to the target branch box on the target branch box.

[0099] In some embodiments, determining the address coding interval corresponding to the target branch box based on the dial address corresponding to the target branch box and the maximum number of connections corresponding to the target branch box may include:

[0100] The dial address corresponding to the target branch box is subtracted by one, and the product of the value obtained after the subtraction operation and the maximum connectable number corresponding to the target branch box is determined as the address coding interval corresponding to the target branch box.

[0101] In this embodiment, when the dial address corresponding to the target branch box is obtained, the dial address can be subtracted by one, and then the value obtained after the subtraction operation is multiplied by the maximum number of connections, and the product of the two is determined as the address coding interval corresponding to the target branch box.

[0102] In the actual implementation process, the target communication address corresponding to each indoor entity connected to the target branch box can be generated based on the following formula:

[0103] IN_ADDR=(m-1)*Nmax+n, where IN_ADDR is the target communication address corresponding to the indoor entity, m is the dial address corresponding to the target branch box, Nmax is the maximum number of connections corresponding to the target branch box, and n is the connection order of the indoor entity on the target branch box.

[0104] like Figure 3 As shown, when the dial address of the target branch box is successfully read, a virtual address (target communication address) can be generated for the indoor entity connected to the target branch box. When the target communication addresses of all indoor entities connected to the target branch box are generated, it can be determined that the communication address of the indoor entity has been successfully virtualized.

[0105] According to the control method of the refrigeration equipment provided in the embodiment of the present application, by manually setting the dial address of the branch box, the discreteness of the communication address of the indoor entity connected to the branch box can be ensured, and the conflict of the target communication address corresponding to the indoor entity can be effectively reduced, thereby reducing the communication abnormality caused by the conflict, thereby improving the stability and reliability of the communication.

[0106] In some embodiments, determining the address code interval corresponding to the target branch box based on the random number generated by the target branch box and the maximum connectable number corresponding to the target branch box may include:

[0107] The product of the random number generated based on the target branch box and the maximum connectable number corresponding to the target branch box is determined as the address code interval corresponding to the target branch box.

[0108] In this embodiment, the product of the random number and the maximum connectable number is determined as the address code interval corresponding to the target branch box.

[0109] In actual execution, the target communication address can be generated based on the following formula:

[0110] Rand_ADDR=Nmax*X+(n-1), where Rand_ADDR is the target communication address, Nmax is the maximum number of connections corresponding to the target branch box, X is a random number, and n is the connection order of the indoor entities on the target branch box.

[0111] In some embodiments, generating a random number based on a target splitter box may include:

[0112] A random number is determined based on a sampling value corresponding to a target temperature sensor in the at least one temperature sensor and a count value corresponding to a target timer in the at least one timer.

[0113] In this embodiment, the target junction box may include at least one temperature sensor and at least one timer.

[0114] One or more target temperature sensors (eg, two target temperature sensors) may be randomly acquired from the at least one temperature sensor, and AD sampling values ​​may be acquired from the target temperature sensors.

[0115] One or more target timers (eg, two target timers) may be acquired from at least one timer to acquire the count value of the count register from the target timer.

[0116] Then, the obtained AD sampling value and the obtained count value may be summed to determine a random number.

[0117] In some embodiments, generating a random number based on a target splitter box may include:

[0118] The random number is determined based on the identifier corresponding to the chip in the target branch box.

[0119] In this embodiment, the chips in the target branch box may include an MCU chip (Microcontroller Unit) and a MAC chip (Media Access Control), or may also include other types of chips, such as driver chips and storage chips, etc., which are not limited in this application.

[0120] For example, the ID of the MCU chip may be determined as a random number, and the MCU chip ID is a unique identifier inherent in the hardware.

[0121] When an Ethernet or Wi-Fi module is used in the system, the MAC address can be obtained and determined as a random number.

[0122] In the actual implementation process, Figure 4 As shown, a random number can be generated by the sum of the AD sampling value corresponding to the target temperature sensor and the count value corresponding to the target timer, and then a random address corresponding to the indoor entity connected to the target branch box is generated based on the random number. When the target communication addresses of all indoor entities connected to the target branch box are generated, it can be determined that the communication addresses of the indoor entities have been successfully virtualized.

[0123] According to the control method of the refrigeration equipment provided in the embodiment of the present application, the target communication address of each indoor entity is generated by generating random numbers and random addresses, thereby ensuring the discreteness of the addresses of the indoor entities connected to each branch box, thereby greatly reducing the conflicts in the target communication addresses of the indoor entities, reducing the risk of misoperation, ensuring the stability and reliability of communication, and having a high degree of automation, shortening the debugging cycle, and improving the user experience.

[0124] In some embodiments, step 120 may include:

[0125] In response to the addressing request, the target communication address corresponding to each indoor subject is sequentially sent to the outdoor subject based on the target time interval, and the new addressing request sent by the outdoor subject is detected;

[0126] When a target number of new addressing requests are received within a target period, the target communication address is updated based on the maximum number of connections corresponding to the target branch box and the connection order of the indoor entities connected to the target branch box on the target branch box;

[0127] In response to the new addressing request, an updated target communication address is sent to the outdoor subject.

[0128] In this embodiment, the target time interval is the frequency at which the target branch box sends the communication address to the outdoor entity. For example, it can be sent every few seconds or milliseconds. The target time interval can be set to 20ms, or it can be other values. It can be customized based on the user and is not limited in this application.

[0129] A branch box is connected to at least one indoor entity. During the line grabbing process, random address data packets can be sent one by one with the random address (target communication address) of the indoor entity based on a fixed time interval, which can reduce the conflict caused by multiple devices sending data at the same time.

[0130] In some embodiments, retransmission processing and conflict processing can be processed based on standard procedures agreed upon in the protocol, and the system can process operations such as data packet retransmission, conflict detection and resolution based on preset rules.

[0131] The target communication address is a unique identifier for each indoor subject and is used for communication between outdoor subjects and indoor subjects. In the case of repeated communication addresses, communication conflicts will occur.

[0132] The new addressing request is generated by the outdoor entity when it determines that there are at least two identical target communication addresses among all target communication addresses based on the target communication addresses corresponding to the indoor entities connected to each branch box. That is, in the event of a communication address conflict or other problems, the outdoor entity can send a new addressing request to the target branch box so that the target branch box can update the target communication address.

[0133] In the event of a collision of randomly generated communication addresses, the outdoor entity can re-initiate a broadcast addressing request. When the target branch box receives the target number of addressing requests (such as 3 times) within the target time period, the target branch box can re-obtain the random number and recalculate the communication addresses of each indoor entity, and conduct addressing interaction again.

[0134] According to the control method of the refrigeration equipment provided in the embodiment of the present application, when a collision occurs in the random addresses corresponding to the indoor main body, the stability and reliability of the automatic addressing process are ensured by updating the target communication address corresponding to the indoor main body and performing addressing interaction again, thereby improving the stability of the communication process.

[0135] In some embodiments, when the device leaves the factory, the outdoor body can broadcast an addressing request, all indoor bodies can establish communication with the outdoor body based on a random address, the outdoor body can assign an address to the indoor body, and when the indoor body returns confirmation information based on the assigned address, the assigned address can be determined as the communication address of the indoor body.

[0136] like Figure 3 and Figure 4 As shown, when the target branch box receives the addressing request sent by the outdoor unit, it can set the virtual indoor unit random address sending request. When the bus of the outdoor main body is in an idle state, the target branch box can send the random address of the indoor main body to the outdoor main body one by one based on the target time interval;

[0137] When receiving the outdoor subject address change and it matches its own address, it can reply a confirmation character (ACK) to the outdoor subject. When receiving the outdoor subject address confirmation and it matches its own address, it can reply a confirmation character to the outdoor subject, which can confirm that the address allocation is completed and enter normal communication.

[0138] In some embodiments, each branch box is connected to at least part of the indoor body through a first communication network, and the other indoor bodies among the multiple indoor bodies except the indoor body connected to the branch box are connected to the outdoor body through a second communication network.

[0139] In this embodiment, if Figure 2 As shown, each branch box can be connected to at least part of the indoor main body through the first communication network (network 2), for example, the branch box 1 can be connected to the indoor unit 1-1, the indoor unit 1-2, the indoor unit 1-3, the indoor unit 1-4 and the indoor unit 1-5 through the first communication network; the branch box N can be connected to the indoor unit N-1, the indoor unit N-2 and the indoor unit N-3 through the first communication network.

[0140] The first communication network may be current loop communication.

[0141] Other indoor entities can be connected to the outdoor entity via the second communication network (network 1), for example, the indoor units 2-1 and 3-1 can be directly connected to the outdoor entity via the second communication network.

[0142] Among them, the second communication network can be a multi-connected internal and external unit communication network, which can adopt a bus method, including Home Bus System (HBS), RS485 and CAN bus (Controller Area Network), etc. It can be selected based on user needs and is not limited in this application.

[0143] During the actual implementation process, if the user needs to expand the indoor body, the indoor body can be directly connected to the outdoor body without the need to set up a separate branch box; if a high-power indoor body needs to be connected, the indoor body can be connected to the outdoor body separately, and this application does not limit it.

[0144] According to the control method of the refrigeration equipment provided in the embodiment of the present application, the branch box is connected to at least part of the indoor main body through the first communication network, and other indoor main bodies can be connected to the outdoor main body through the second communication network. The outdoor main body can be connected to the indoor main body and the branch box at the same time. The outdoor main body can automatically match and combine the number of devices of the bus node based on demand, thereby realizing interactive communication between the indoor main body and the branch box on the same bus, and realizing seamless connection with the bus network of the outdoor main body, thereby ensuring the normal communication interaction and address allocation between the outdoor main body and other indoor main bodies, and broadening the applicable scenarios.
