Technical Field

[0001] This application belongs to the field of refrigeration equipment, and in particular relates to a testing device and a data processing method for refrigeration equipment. Background Technology

[0002] Air conditioners often have many faults that cannot be displayed on the control panel or wired controller. These require the use of after-sales diagnostic tools to connect the outdoor unit to a computer to check operating parameters and identify undisplayed faults. This allows for the determination of air conditioner parameters and fault parameters, ultimately leading to the identification of the cause and corresponding solutions. However, many outdoor units are installed outdoors, often on high floors or in specific environments, making it difficult for after-sales personnel to access them and connect to the computer via USB. This hinders the identification of the cause and error, increases repair time, and results in a poor user experience for customers. Summary of the Invention

[0064] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0065] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0066] The control method of the detection equipment and the refrigeration equipment provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0067] like Figure 1 As shown, this application provides a detection device.

[0068] The detection device is used to: receive a first operating parameter sent by an outdoor unit, and perform at least one operation of storing the first operating parameter and forwarding the first operating parameter to a target terminal.

[0069] In this embodiment, the outdoor unit can be the outdoor unit of a refrigeration device.

[0070] Refrigeration equipment can be understood in a broad sense, including but not limited to air conditioners, refrigeration units, and evaporative coolers. Refrigeration equipment has diverse structural forms and a wide range of applications.

[0071] Air conditioners can include wall-mounted air conditioners, floor-standing air conditioners, central air conditioners, and window air conditioners.

[0072] Refrigeration equipment can include indoor units and outdoor units.

[0073] The indoor unit is used to regulate the temperature and humidity of the indoor air.

[0074] The outdoor unit is used to compress the refrigerant and release or absorb heat in the refrigerant cycle.

[0075] The indoor unit is electrically connected to the outdoor unit.

[0076] The indoor unit and the outdoor unit can be connected by wired power.

[0077] For example, the indoor unit and the outdoor unit are connected via a current loop communication method.

[0078] In some embodiments, when the indoor unit and the outdoor unit are connected via a current loop communication method, data can be transmitted by controlling the current changes on the live wire and the neutral wire.

[0079] In actual operation, the indoor and outdoor units can transmit data to each other, such as... Figure 1 As shown, the indoor unit can send relevant operating data of the refrigeration equipment, such as the indoor unit's temperature setpoint, operating mode, fan speed setting, and humidity information, to the outdoor unit. The outdoor unit can send conventional fault status or information data, such as compressor operating status, fan status, and fault codes, to the indoor unit.

[0080] It is understandable that the data sent from the indoor unit to the outdoor unit is the relevant operating data of the indoor unit of the refrigeration equipment, while the data sent from the outdoor unit to the indoor unit is the data of a regular fault status or a regular fault information.

[0081] The first operating parameter is the relevant operating parameter of the refrigeration equipment.

[0082] The first operating parameter may include at least one of the second operating parameter of the outdoor unit and the third operating parameter of the indoor unit. The first operating parameter is used for data processing by the target terminal.

[0083] The second operating parameter may include relevant operating data of the outdoor unit of the refrigeration equipment.

[0084] For example, the second operating parameter may include temperature data such as outdoor dry-bulb temperature, pressure data such as condensation pressure, power data such as compressor power, and performance parameters such as cooling capacity.

[0085] The third operating parameter may include relevant operating data of the indoor unit sent to the outdoor unit by the indoor unit for the refrigeration equipment.

[0086] For example, the third operating parameter may include temperature setpoint, operating mode, fan speed setting, and humidity information.

[0087] like Figure 2 As shown, in actual operation, the outdoor unit can send at least one of the second and third operating parameters, i.e., the first operating parameter, to the testing equipment.

[0088] The outdoor unit can send the first working parameters to the detection equipment frame by frame.

[0089] A single frame can specify a set of relevant operating parameters for all refrigeration equipment included in the protocol.

[0090] The testing equipment can be installed inside the outdoor unit or independently outside the outdoor unit, and is wired to the outdoor unit of the refrigeration equipment.

[0091] The wired connection method between the testing equipment and the outdoor unit can include: traditional serial communication, differential signal serial communication, or synchronous serial communication.

[0092] In some embodiments, the detection device and the outdoor unit can be connected via asynchronous serial communication.

[0093] In this embodiment, the asynchronous serial communication method (UART) is a wired connection method. In the case of asynchronous serial communication, the detection device and the outdoor unit transmit data through a data cable.

[0094] In actual operation, the outdoor unit converts the first working parameter to be sent into a parallel signal, then converts the parallel signal into a serial signal through the drive circuit, and sends the serial signal to the data line through the transmitting circuit. The detection device then uses the receiving circuit to restore the signal on the data line into a parallel signal, and then uses the decoding circuit to convert the parallel signal back into the original first working parameter, thus completing the data transmission between the detection device and the outdoor unit in the asynchronous serial communication mode.

[0095] According to the testing equipment provided in the embodiments of this application, by connecting the testing equipment and the outdoor unit through asynchronous serial communication, fast and flexible data transmission between the testing equipment and the outdoor unit can be achieved, thereby improving transmission efficiency.

[0096] The target terminal is used to receive, process, and / or display the first operating parameters forwarded by the detection device.

[0097] The target terminal can be wirelessly connected to the detection equipment.

[0098] The wireless connection method between the target terminal and the detection equipment can include WIFI or Bluetooth.

[0099] For example, when the target terminal is wirelessly connected to the detection equipment, the target terminal can wirelessly connect to the detection equipment via a WIFI module, such as... Figure 1 As shown, this is to achieve wireless data transmission between the target terminal and the detection equipment.

[0100] The WIFI module can be wired to the detection equipment via UART.

[0101] Of course, the target terminal can also be connected to the detection equipment through other wireless communication methods to realize data transmission between the target terminal and the detection equipment, which is not limited here.

[0102] In other embodiments, the target terminal may also be wired to the detection device. In this case, the data transmission between the target terminal and the detection device is similar to the data transmission between the target terminal and the refrigeration device in the traditional case, which will not be described in detail here.

[0103] The target terminal may include at least one of a mobile terminal or a network terminal.

[0104] Mobile terminals can include mobile apps, etc.

[0105] Network terminals can include computers (PCs) or workstations, etc.

[0106] In actual execution, the target terminal can receive and store the first working parameters forwarded by the detection device, process the first working parameters, and display the first working parameters and the processing results of the first working parameters. The processing results of the first working parameters may include conventional or complex fault information of the refrigeration equipment.

[0107] It should be noted that when the outdoor unit sends the first working parameters to the detection device frame by frame, the detection device can forward the first working parameters to the target terminal frame by frame. The target terminal passively receives and stores the first working parameters forwarded by the detection device frame by frame.

[0108] The detection device can forward the first working parameter to the target terminal immediately after receiving it, or it can forward it to the target terminal at certain time intervals.

[0109] It is understood that in this embodiment, a detection device electrically connected to the outdoor unit is provided. This detection device can receive the first operating parameters sent by the outdoor unit and can store the first operating parameters or forward the first operating parameters to the target terminal. The target terminal can receive, store and process the first operating parameters forwarded by the detection device, thereby obtaining the conventional or complex fault information of the refrigeration equipment, and can display the first operating parameters and the conventional or complex fault information of the refrigeration equipment.

[0110] During the research and development process, the inventors discovered that methods for detecting refrigeration equipment faults can be divided into two categories. One category involves sending fault codes or numbers from the outdoor unit to the indoor unit under normal fault conditions. The indoor unit then displays the fault codes on its display panel or wired controller. Users can determine the cause of the fault by referring to the fault code table, thereby locating the fault and devising a solution. The other category involves complex fault conditions where the display panel or wired controller cannot display fault codes. In such cases, a wired connection to a computer using a fault detection tool provided by after-sales service is required to detect the operating parameters and fault information of the refrigeration equipment. However, the outdoor unit is often located outdoors, on a high floor, or in certain specific environments, which may prevent maintenance personnel from accessing it and thus from connecting to the computer via USB. This makes it impossible to locate the cause and error, leading to increased repair time and a poor user experience for customers.

[0111] In this application, by setting up a detection device electrically connected to the outdoor unit of the refrigeration equipment, the detection device can be used to receive and store the first operating parameters sent by the outdoor unit, realize the transfer of relevant operating parameters of the refrigeration equipment, and can also be used to forward the first operating parameters to the target terminal, thereby realizing the wireless transmission of relevant operating parameters of the refrigeration equipment. On this basis, the data processing of the first operating parameters can be performed based on the target terminal, thereby realizing complex processing of relevant operating parameters of the refrigeration equipment based on wireless transmission, providing more convenient information extraction and display of relevant operating parameters of the refrigeration equipment, and improving the user experience.

[0112] According to the detection device provided in the embodiments of this application, by setting up a detection device electrically connected to the outdoor unit of the refrigeration equipment, the detection device can be used to receive and store the first working parameters sent by the outdoor unit, and can be used to forward the first working parameters to the target terminal. It can realize the transfer and wireless transmission of the relevant working parameters of the refrigeration equipment based on the detection device. On this basis, the data processing of the first working parameters can be performed based on the target terminal, thereby realizing the complex processing of the relevant working parameters of the refrigeration equipment based on wireless transmission, providing more convenient information extraction and display of the relevant working parameters of the refrigeration equipment, and improving the user experience.

[0113] In some embodiments, the detection device may include a microcontroller and a flash memory chip.

[0114] In this embodiment, the microcontroller is a microcomputer that integrates functions such as CPU and input / output interface on a single chip, and is used to control various operations of the detection equipment.

[0115] For example, microcontrollers can include STM32, PIC, AVR, and MSP430.

[0116] The microcontroller is wired to the outdoor unit and electrically connected to the target terminal.

[0117] The microcontroller can be connected to the target terminal via wired or wireless means.

[0118] It is understandable that the testing equipment can be connected to other devices or equipment based on a microcontroller, which may include outdoor units and target terminals.

[0119] For example, a microcontroller can connect to the outdoor unit and the target terminal separately using differential signal serial communication to enable the connection between the detection device and the outdoor unit and the target terminal, thereby achieving data transmission.

[0120] In actual operation, the microcontroller can be used to perform operations such as receiving, storing, or forwarding the first working parameters of the detection device.

[0121] In some embodiments, the microcontroller may be a Renesas R5F100JG.

[0122] In this embodiment, the Renesas R5F100JG is a 16-bit microcontroller that provides ultra-low power technology and rich peripheral interfaces and functions, thereby improving the processing performance of the microprocessor 101 and the flexibility of connecting with other devices or equipment.

[0123] For example, the Renesas R5F100JG can provide two UART interfaces, which can be used to enable communication between the testing device and the outdoor unit, as well as the testing device's WIFI communication. This allows the testing device to receive, store, or forward the first working parameters, and enables the testing device to establish a wireless communication connection with the target terminal based on the WIFI module.

[0124] Flash memory chips are a special type of non-volatile memory that allows users to erase and rewrite data, making them a rewritable storage device.

[0125] For example, flash memory chips can include types such as NOR Flash and NAND Flash.

[0126] In some embodiments, the flash memory chip may be W25Q128FV.

[0127] In this embodiment, the W25Q128FV is a 128M-bit serial NOR flash memory chip that can provide low power consumption and ensure storage efficiency.

[0128] Flash memory chips can be wired to a microcontroller.

[0129] For example, the wired electrical connection between the flash memory chip and the microcontroller can include URAT, I2C, or SPI.

[0130] In some embodiments, the flash memory chip and the microcontroller can be connected via CSI communication.

[0131] In this embodiment, CSI is a wired communication interface that can be used for high-speed data communication between the flash memory chip and the microcontroller to improve data transmission efficiency.

[0132] In actual operation, the flash memory chip can be used to store the first working parameters received by the detection equipment.

[0133] Of course, in other embodiments, the actual storage of the first working parameters received by the detection device can also be other storage devices, such as memory cards, etc., which are not limited here.

[0134] According to the detection device provided in the embodiments of this application, by setting a microcontroller that is wired to the outdoor unit and a flash memory chip that is electrically connected to the microcontroller and the target terminal respectively, the detection device can realize the operation functions such as receiving, storing or forwarding first working parameters, thereby realizing the function of transferring and wirelessly transmitting relevant working parameters of the refrigeration equipment based on the detection device.

[0135] In some embodiments, the detection device may further include: other memory and an external clock source.

[0136] In this embodiment, the other memory is the memory used by the microcontroller to store program code and data during program execution.

[0137] Other memory may include ROM and RAM.

[0138] ROM is used to store program code, and RAM is used to store data during program execution.

[0139] ROM is a non-volatile memory, a read-only memory, whose data is not lost after power is turned off.

[0140] RAM is a type of volatile memory, also known as random access memory. It can be frequently read and written and supports random access, but the data will be lost when power is off.

[0141] In actual implementation, a 128K ROM and a 12K RAM can be selected, or other ROM and RAM of different capacities can be selected. This application does not limit the selection.

[0142] Other connection methods between memory and microcontroller can refer to the connection methods between flash memory chips and microcontroller, which will not be elaborated here.

[0143] An external clock source is used to provide clock signals to the microcontroller, which in turn drive the microcontroller's internal clock system.

[0144] The microcontroller’s internal clock system is a set of hardware and functions used to generate and distribute clock signals to drive the processor core, peripherals and memory inside the MCU. These clock signals ensure that the MCU can execute instructions and process data at a consistent speed.

[0145] In actual implementation, a 1MHz crystal oscillator can be used as an external clock source. The crystal oscillator is a hardware component that provides a stable clock signal to drive the clock system of the microcontroller. 1MHz is the frequency of the crystal oscillator, which is one megahertz (MHz), and is also the clock frequency of the microcontroller.

[0146] Of course, in other embodiments, crystal oscillators of other frequencies may be used, and this application does not limit them here.

[0147] In some embodiments, the flash memory chip may include:

[0148] A first storage area, wherein a first programmable page of the first storage area is used to store first data;

[0149] The second storage area is used to store the first working parameters.

[0150] In this embodiment, the flash memory chip may include two storage areas.

[0151] The storage area can be a combination of sectors of a flash memory chip.

[0152] A sector is composed of multiple programmable pages distributed across an array of flash memory chips.

[0153] For example, when the flash memory chip is a W25Q128FV chip, the W25Q128FV chip array is distributed as 65,536 programmable pages, each page being 256 bytes in size. These pages can be grouped into 16-page sets (4KB), which is one sector.

[0154] In actual execution, the first working parameters can be stored in frames, in units of sectors.

[0155] For example, a sector can store a frame of relevant operating parameters of the refrigeration equipment sent by the outdoor unit.

[0156] It is understandable that, when the outdoor unit sends the first working parameters to the detection device frame by frame, the flash memory chip of the detection device can store the first working parameters frame by frame in units of sectors.

[0157] In actual operation, flash memory chips can also erase data in units of sectors.

[0158] Data erasure is the first working parameter used to delete sector storage.

[0159] For example, when the flash memory chip is a W25Q128FV chip, the W25Q128FV chip array is distributed with 65,536 programmable pages, each page being 256 bytes in size. Data erasure can be performed in groups of 16 pages (4KB sector erasure), meaning the W25Q128FV has 256 erasable blocks, or 4,096 erasable sectors.

[0160] In actual execution, the first storage area may include at least one sector, and the second storage area may include all sectors other than the first storage area. The number of sectors in the first storage area is much smaller than the number of sectors in the second storage area.

[0161] For example, if the flash memory chip is a W25Q128FV chip, and the first storage area includes sector 1, then the second storage area may include sectors 2 to 4096.

[0162] The first programmable page can be a portion of the programmable page of the first sector within the first storage area.

[0163] Of course, in other embodiments, the first programmable page can be other programmable pages within the first storage area, which is not limited herein.

[0164] The first data can be information such as the quantity or position of the first working parameter.

[0165] The first data may include at least one of the following: the number of data stores, the current storage address, and a flag indicating whether the storage is full.

[0166] The number of data storage units is the same as the number of storage units in the first working parameter.

[0167] For example, the flash memory chip stores the first working parameters for n frames, where n is a positive integer.

[0168] The current storage address can be the storage location information of the first working parameter in the second storage area.

[0169] For example, the last data of the first working parameter of the latest frame is stored in the xth sector or the yth page of the xth sector in the second storage area, where x and y are both positive integers. Of course, other storage location information can also be used, which is not limited in this application.

[0170] The full status indicator can be a flag indicating whether the flash memory chip is full, for example, it can include: full or not full.

[0171] In actual execution, when the amount of the first working parameter data is small, the first data can be stored only in the first page of the first sector of the first storage area, while other programmable pages can be reserved.

[0172] Of course, in other embodiments, the first data may also be stored in one or more other programmable pages in the first storage area, which is not limited herein.

[0173] In actual operation, when the microcontroller receives the first working parameter sent by the outdoor unit, the microcontroller writes the first working parameter to the flash memory chip page by page. The data storage quantity, current storage address and whether the storage is full are stored in the first storage area, and the first working parameter is stored in the second storage area, which facilitates the monitoring and management of the first working parameter.

[0174] In some embodiments, the first operating parameters may be written sequentially to the second storage area, starting from the first programmable page of the second storage area.

[0175] In other embodiments, the flash memory chip may also be configured as multiple other storage areas, which are not limited herein.

[0176] According to the detection device provided in the embodiments of this application, by setting the flash memory chip as a first storage area and a second storage area, it is possible to simultaneously store information data such as the quantity or location of the first working parameter and the first working parameter itself, and store them separately, so as to more conveniently monitor and manage the first working parameter.

[0177] In some embodiments, when the cooling device is powered on and initialized, the detection device performs a stored data read operation to read historical first operating parameters stored in the detection device.

[0178] In this embodiment, the power-on initialization of the refrigeration equipment can be performed after the refrigeration equipment has been powered off and then powered on again.

[0179] The first historical operating parameter can be the first operating parameter stored in the testing equipment before the refrigeration equipment was powered off.

[0180] In actual execution, the power-on initialization of the refrigeration equipment can be performed after the refrigeration equipment has been powered off and then powered on again. At this time, the refrigeration equipment has not yet generated new relevant operating parameters. The detection equipment can perform a data reading operation to read the relevant operating parameters of the refrigeration equipment stored in the detection equipment before the power failure. These parameters can then be sent to the target terminal for display or analysis.

[0181] In some embodiments, a sector erase operation may be performed before the flash memory chip stores the first operating parameters.

[0182] In this embodiment, during actual execution, when the flash memory chip is full or the cooling device is powered on and initialized, a sector erase operation can be performed before the flash memory chip stores the first working parameters. This sector erase operation can erase all or part of the storage content to free up storage space in the flash memory chip to store the new first working parameters.

[0183] In some embodiments, forwarding the first working parameter to the target terminal may include:

[0184] Receive request data sent by the target terminal;

[0185] In response to the requested data, the first operating parameters stored in the detection device are read based on the target reading method;

[0186] Send the first working parameters to be read to the target terminal.

[0187] In this embodiment, the request data can be a request signal sent by the target terminal, etc.

[0188] This request signal can be used to request the reading of the stored content of the detection device at the current moment.

[0189] The storage content stored by the detection device at the current moment may include the first working parameters of multiple frames.

[0190] The target reading method can be a different reading method for the content stored in the detection device, determined based on the storage status of the detection device.

[0191] The storage status of the detection device can include: 1 / 3 storage status, 1 / 2 storage status, or full storage status, etc.

[0192] Of course, other storage states may also be included, but this application does not limit them here.

[0193] Different reading methods can be reflected in different reading orders or positions, etc.

[0194] In actual execution, the detection device receives and responds to the request data sent by the target terminal, and determines different reading methods for the content stored in the detection device based on different storage states, and then performs the reading operation, thereby sending the first working parameters for reading to the target terminal.

[0195] It is understood that in this embodiment, the target terminal can actively request to read the first operating parameters in the detection device.

[0196] According to the detection device provided in the embodiments of this application, by receiving request data sent by the target terminal and responding to the request data, sending the first working parameters read from the detection device to the target terminal, the target terminal can actively access the detection device, improve the flexibility of obtaining relevant working parameters of the refrigeration device based on the target terminal, and enhance the user experience.

[0197] In some embodiments, reading the first operating parameter stored in the detection device based on the target reading method may include:

[0198] When the detection equipment is full, data is read from the first storage area included in the detection equipment until all the first working parameters are read.

[0199] If the detection device is not full, data is read from the second storage area included in the detection device until all the first working parameters are read.

[0200] In this embodiment, the different storage states of the detection device can be divided into full storage and not full storage.

[0201] Whether the testing equipment is fully or partially filled, the specific logic for reading the stored content is determined by the autonomous control logic based on the flash memory chip.

[0202] In actual execution, when the detection device is full, data is read starting from the first storage area included in the detection device. This can be done by starting with the first data stored in the first storage area, reading the current storage address in the first data, and then reading data from the second storage area starting from the recorded address. When the last page of the last sector of the second storage area has been read, data is read again starting from the first page of the first sector of the second storage area. After reading the recorded address, data reading and data transmission stop.

[0203] If the detection device is not full, data is read from the second storage area included in the detection device. That is, data can be read from the first page of the first sector of the second storage area. After all the recorded data has been read, the data reading operation and data transmission are stopped.

[0204] According to the detection device provided in the embodiments of this application, by determining different reading methods for the stored content of the detection device based on different storage states of the detection device, and then performing the reading operation, the logic of the reading operation can be guaranteed, a clearer reading operation can be achieved, and the accuracy and reliability of the first working parameters of the reading sent to the target terminal can be guaranteed.

[0205] This application also provides a data processing method for a refrigeration device.

[0206] The following section describes the data processing method for this refrigeration equipment, using the testing equipment as the primary instrument.

[0207] like Figure 3 As shown, the data processing method includes steps 310 and 320.

[0208] Step 310: Receive the first operating parameters sent by the outdoor unit;

[0209] In this step, the first operating parameter includes at least one of the second operating parameter of the outdoor unit and the third operating parameter of the indoor unit, wherein the third operating parameter is sent from the indoor unit to the outdoor unit.

[0210] like Figure 6 As shown, in actual operation, the outdoor unit of the refrigeration equipment can send the first operating parameters to the detection equipment, and the detection equipment can receive the first operating parameters.

[0211] Step 320: Perform at least one of the following operations: storing the first working parameter and forwarding the first working parameter to the target terminal.

[0212] In this step, the first working parameter is used for data processing by the target terminal.

[0213] like Figure 6 As shown, in actual execution, the detection device receives the first working parameters sent by the outdoor unit of the refrigeration equipment, can store the first working parameters, and can forward the first working parameters to the target terminal. The target terminal then performs subsequent processing on the first working parameters, thereby obtaining the fault information of the refrigeration equipment.

[0214] According to the data processing method for refrigeration equipment provided in the embodiments of this application, by receiving and storing the first working parameters sent by the outdoor unit based on the detection device, and forwarding the first working parameters to the target terminal, the relevant working parameters of the refrigeration equipment can be transferred and wirelessly transmitted based on the detection device. On this basis, the data processing of the first working parameters is performed based on the target terminal, thereby realizing the complex processing of the relevant working parameters of the refrigeration equipment based on wireless transmission, providing more convenient information extraction and display of the relevant working parameters of the refrigeration equipment, and improving the user experience.

[0215] In some embodiments, step 320 further includes:

[0216] Receive request data sent by the target terminal;

[0217] In response to the requested data, the first operating parameters within the detection device are sent to the target terminal.

[0218] In this embodiment, the request data sent by the target terminal can be the storage content of the detection device at the current moment, which the target terminal uses to request the transmission of.

[0219] The stored content of the detection device at the current moment may include multiple frames of first working parameters.

[0220] like Figure 6 As shown, in actual execution, the target terminal can send a request to the detection device to read the storage content of the detection device at the current moment. In response to the request, the detection device sends the first working parameters of multiple frames stored by the detection device at the current moment to the target terminal.

[0221] According to the data processing method for refrigeration equipment provided in the embodiments of this application, by receiving request data sent by the target terminal based on the detection device and sending the stored content stored in the detection device at the current time, the target terminal can actively access the detection device, improve the flexibility of obtaining relevant working parameters of the refrigeration equipment based on the target terminal, and enhance the user experience.

[0222] like Figure 7 As shown, in some embodiments, this application also provides a data processing device for a refrigeration device, applied to a testing device; the refrigeration device includes an indoor unit and an outdoor unit, which are electrically connected; the testing device is wiredly connected to the outdoor unit; the device includes: a first processing module 710 and a second processing module 720.

[0223] The first processing module 710 receives the first operating parameters sent by the outdoor unit;

[0224] The second processing module 720 performs at least one operation: storing the first working parameters and forwarding the first working parameters to the target terminal.

[0225] In some embodiments, the second processing module 720 may also be used for:

[0226] Receive request data sent by the target terminal;

[0227] In response to the requested data, the first operating parameters within the detection device are sent to the target terminal. This application also provides a data processing method for a refrigeration device.

[0228] The following section uses refrigeration equipment as the main implementer to explain the data processing method of the refrigeration equipment.

[0229] like Figure 4 As shown, the data processing method includes: step 410.

[0230] Step 410: During the operation of the refrigeration equipment, the outdoor unit sends the first working parameters to the detection equipment based on the target duration.

[0231] In this step, the first operating parameter includes at least one of the second operating parameter of the outdoor unit and the third operating parameter of the indoor unit, wherein the third operating parameter is sent from the indoor unit to the outdoor unit.

[0232] The first operating parameter is used by the detection equipment to store or forward to at least one of the target terminals.

[0233] The target duration can be a certain sending interval.

[0234] Understandably, the outdoor unit can send initial operating parameters to the detection equipment at certain time intervals.

[0235] For example, the outdoor unit can send a frame of the first working parameters to the detection device every 3 seconds, 5 seconds, or 7 seconds.

[0236] like Figure 6 As shown, in actual operation, the outdoor unit of the refrigeration equipment can send the first working parameters to the detection device at certain time intervals. The detection device receives and stores the first working parameters at regular intervals, and forwards them to the target terminal at regular intervals. The target terminal then receives the first working parameters at regular intervals and processes them at regular intervals, thereby obtaining real-time fault information of the refrigeration equipment.

[0237] Since the target terminal receives the first working parameters stored and forwarded by the detection device, the time interval for the target terminal to receive the first working parameters is greater than the time interval for the outdoor unit to send the first working parameters to the detection device.

[0238] According to the data processing method for refrigeration equipment provided in the embodiments of this application, by periodically receiving and storing the first working parameters sent periodically by the outdoor unit based on the detection device, and periodically forwarding the first working parameters to the target terminal, it is possible to realize the real-time transfer and wireless transmission of the relevant working parameters of the refrigeration equipment based on the detection device; on this basis, the data processing of the first working parameters is performed periodically based on the target terminal, thereby realizing the complex processing of the relevant working parameters of the refrigeration equipment based on wireless transmission, providing more convenient information extraction and real-time display of the relevant working parameters of the refrigeration equipment, and improving the user experience.

[0239] like Figure 8 As shown, in some embodiments, this application also provides a data processing device for a refrigeration device, applied to the refrigeration device; the refrigeration device includes an indoor unit and an outdoor unit, which are electrically connected; a detection device is wiredly connected to the outdoor unit; the device includes: a first processing module 810.

[0240] The first processing module 810 is used to send a first working parameter to the detection device based on a target duration during the operation of the refrigeration equipment. The first working parameter includes at least one of a second working parameter of the outdoor unit and a third working parameter of the indoor unit, wherein the third working parameter is sent from the indoor unit to the outdoor unit. The first working parameter is used for the detection device to store or forward to at least one of the target terminals.

[0241] This application also provides a data processing method for a refrigeration device.

[0242] The following section describes the data processing method for this refrigeration equipment, taking the target terminal as the executing entity.

[0243] like Figure 5 As shown, the data processing method includes steps 510 and 520.

[0244] Step 510: Receive the first working parameters sent by the testing equipment.

[0245] In this step, the first operating parameter includes at least one of the second operating parameter of the outdoor unit and the third operating parameter of the indoor unit, wherein the third operating parameter is sent from the indoor unit to the outdoor unit.

[0246] like Figure 6 As shown, in the actual execution process, the detection equipment receives the first working parameters sent by the outdoor unit of the refrigeration equipment, and then forwards the first working parameters to the target terminal, which then receives the first working parameters.

[0247] Step 520: Process the first working parameters.

[0248] In this step, such as Figure 6 As shown, in the actual execution process, after the target terminal receives the first working parameter, it can process the first working parameter and then display the processed first working parameter.

[0249] In some embodiments, processing the first operating parameter may include:

[0250] Based on the first operating parameters, the fault information of the refrigeration equipment is determined.

[0251] In this embodiment, the fault information of the refrigeration equipment may include conventional fault information and complex fault information.

[0252] like Figure 6 As shown, in actual execution, after receiving the first working parameter, the target terminal can process the first working parameter to obtain the conventional fault information and complex fault information of the refrigeration equipment, and then display the conventional fault information and complex fault information of the refrigeration equipment so that users can obtain fault information and determine maintenance countermeasures based on the fault information.

[0253] According to the data processing method for refrigeration equipment provided in the embodiments of this application, by receiving and storing the first working parameters sent by the outdoor unit based on the detection device, and forwarding the first working parameters to the target terminal, the relevant working parameters of the refrigeration equipment can be transferred and wirelessly transmitted based on the detection device. On this basis, the data processing of the first working parameters is performed based on the target terminal, thereby realizing the complex processing of the relevant working parameters of the refrigeration equipment based on wireless transmission, providing more convenient information extraction and display of the relevant working parameters of the refrigeration equipment, and improving the user experience.

[0254] In some embodiments, before receiving the first operating parameters sent by the detection device, the method further includes:

[0255] Send request data to the testing equipment.

[0256] In this embodiment, the request data is used to request the detection device to send first operating parameters.

[0257] The request for the detection device to send the first working parameters may include multiple frames of the first working parameters.

[0258] like Figure 6 As shown, in actual execution, the target terminal can send a request to the detection device to read the first working parameters of multiple frames stored by the detection device at the current moment. The detection device can receive the request and send the first working parameters of multiple frames stored by the detection device at the current moment to the target terminal so as to display the first working parameters of multiple frames at the current moment on the target terminal.

[0259] According to the data processing method for refrigeration equipment provided in the embodiments of this application, by sending request data to the detection equipment based on the target terminal and receiving the storage content stored in the detection equipment at the current time sent by the detection equipment, the target terminal can actively access the detection equipment, improve the flexibility of obtaining relevant working parameters of the refrigeration equipment based on the target terminal, and enhance the user experience.

[0260] In some embodiments, such as Figure 11 As shown, the target terminal can be a mobile app, and the refrigeration equipment can be an air conditioner.

[0261] In this embodiment, the first working parameters received by the target terminal can be displayed on a mobile app.

[0262] In actual implementation, such as Figure 11As shown, after entering the APP, users can click the "check" button. The checker (testing equipment) fixture will always be in paired Bluetooth mode. The APP will display the found devices on the interface, allowing users to select the corresponding checker fixture model and whether it is a commercial or residential air conditioner. Figure 12 As shown, the parameter interface is divided into indoor and outdoor unit sections, which can be switched to query parameters; for example... Figure 13 As shown, you can also click the "Log" function in the upper right corner of the APP to upload the air conditioner operation data stored in the Flash chip of the testing device to the APP, and then download and view the operation data and fault codes.

[0263] like Figure 9 As shown, in some embodiments, this application also provides a data processing device for a refrigeration device, applied to a target terminal, the target terminal being electrically connected to a detection device, the device comprising: a first processing module 910 and a second processing module 920.

[0264] The first processing module 910 is used to receive a first working parameter sent by the detection device. The first working parameter includes at least one of a second working parameter of the outdoor unit and a third working parameter of the indoor unit. The third working parameter is sent from the indoor unit to the outdoor unit.

[0265] The second processing module 920 is used to process the first working parameters.

[0266] In some embodiments, the second processing module 920 may also be used for:

[0267] Based on the first operating parameters, the fault information of the refrigeration equipment is determined.

[0268] In some embodiments, the device may further include a third processing module for:

[0269] Before receiving the first working parameters sent by the testing equipment, a request data is sent to the testing equipment; the request data is used to request the testing equipment to send the first working parameters.

[0270] This application provides a refrigeration device.

[0271] like Figure 10 As shown, the refrigeration equipment includes:

[0272] Outdoor unit 1001;

[0273] Indoor unit 1002.

[0274] The outdoor unit 1001 is used to compress the refrigerant and release or absorb heat in the refrigerant cycle.

[0275] The indoor unit 1002 is used to regulate indoor air temperature and humidity.

[0276] Indoor unit 1002 is electrically connected to outdoor unit 1001.

[0277] The outdoor unit 1001 is used for wired connection to the detection equipment described in any of the above embodiments;

[0278] In actual operation, indoor unit 1002 and outdoor unit 1001 can transmit data to each other. Indoor unit 1002 can send relevant operating data of the refrigeration equipment, such as temperature setting, operating mode, fan speed setting and humidity information, to outdoor unit 1001. Outdoor unit 1001 can send conventional fault status or conventional fault information data, such as compressor operating status, fan status and fault codes, to indoor unit 1002.

[0279] It is understandable that the data sent from indoor unit 1002 to outdoor unit 1001 is the relevant operating data of indoor unit 1002 of the refrigeration equipment, while the data sent from outdoor unit 1001 to indoor unit 1002 is the data of normal fault status or normal fault information.

[0280] The outdoor unit 1001 can send relevant operating data of the outdoor unit 1001 and the indoor unit 1002 of the refrigeration equipment to the detection equipment for storage and forwarding. This data can then be received and processed by the target terminal to display the relevant operating data of the refrigeration equipment and the fault information obtained from processing the data.

[0281] According to the refrigeration equipment provided in the embodiments of this application, by setting a detection device that is wiredly connected to the outdoor unit 1001 of the refrigeration equipment, the detection device can be used to receive and store the first operating parameters sent by the outdoor unit 1001, and can be used to forward the first operating parameters to the target terminal. It can realize the transfer and wireless transmission of the relevant operating parameters of the refrigeration equipment based on the detection device. On this basis, the data processing of the first operating parameters can be performed based on the target terminal, thereby realizing the complex processing of the relevant operating parameters of the refrigeration equipment based on wireless transmission, providing more convenient information extraction and display of the relevant operating parameters of the refrigeration equipment, and improving the user experience.
