[0032] In this regard, an embodiment of the present application provides a test method for a refrigeration device, and the test method for the refrigeration device is applied to the test device, referring to Figure 3 As shown, the testing method of the refrigeration equipment includes the following steps:

[0033] Step 101: After the refrigeration device is powered on, respond to a test instruction sent by a main control board of the refrigeration device to obtain test data of the refrigeration device within a target period of time.

[0034] The test data includes power data of a compressor of the refrigeration equipment and wind speed data of an air outlet of a first chamber of the refrigeration equipment.

[0035] In the embodiment of the present application, after the refrigeration equipment is powered on, the main control board of the refrigeration equipment sends control instructions to various electrical components of the refrigeration equipment, thereby controlling each electrical component to start at a predetermined time interval, and controlling each electrical component to work according to a preset test instruction within a target period, so that the test device can obtain the detection data of each electrical component within the target period. Exemplarily, the electrical components of the refrigeration equipment include air vents, fans, and compressors. Of course, the electrical components of the refrigeration equipment also include heaters, defrost heaters, electric valves, etc., and this application does not make specific restrictions on this.

[0036] In an embodiment of the present application, the test instruction includes an instruction for the test device to obtain the power data of the compressor during operation within the target time period. Of course, the test instruction also includes the wind speed data of the air outlet of the first chamber obtained by the test device during the first time period of the target time period, such as the time period when the fan and the damper are turned on, and the wind speed data of the air outlet of the first chamber obtained during the second time period of the target time period, such as the time period when the fan and the damper are turned off.

[0037] In the embodiment of the present application, the power data may be the power directly collected by the data acquisition module when the compressor is running, or the power data may be the voltage and current collected by the image acquisition module when the compressor is running to indirectly obtain the power. This application does not make any specific restrictions on this.

[0038] In the embodiment of the present application, the wind speed data is the wind speed corresponding to each time point within the target time period.

[0039] In an embodiment of the present application, the refrigeration device includes a plurality of compartments, and the plurality of compartments include a first compartment and a second compartment. Here, the second compartment may be located below the first compartment, and the second compartment may also be located to the left or to the right of the first compartment. Here, the first compartment may be a refrigerating compartment, and the second compartment may be a freezing compartment. A variable temperature space may also be provided between the refrigerating compartment and the freezing compartment. A refrigerating compartment door is provided at the front opening of the refrigerating compartment, and the refrigerating compartment door is used to open or close the refrigerating compartment; a freezing compartment door is provided at the front opening of the freezing compartment, and the freezing compartment door is used to open or close the freezing compartment. It should be noted that when the refrigeration system of the refrigeration device is a single-cycle refrigeration system, the refrigeration system of the refrigerating device refrigerates the freezing compartment, and transmits the cold of the freezing compartment to the refrigerating compartment through the air duct system to achieve cooling and refrigeration of the refrigerating compartment, that is, the temperature of the two compartments of the refrigerating compartment and the freezing compartment is controlled by one refrigeration system.

[0040] It should be noted that in the scenario of online testing of each refrigeration equipment based on the production line, the test time requirement is relatively high. In the related art, when the refrigeration equipment is tested online in the factory, the temperature of the cold storage room is collected, and the fan and damper are judged by judging the temperature change to determine whether they are opened and closed normally. Therefore, the test procedure needs to ensure the refrigeration time of the room. The existing test time of 10 minutes is already the limit, and it is no longer possible to improve efficiency and increase production capacity. When using the test method for refrigeration equipment of the present application, the target time period is usually shorter, and the target time period can be five minutes; in this way, the test time is reduced and the bottleneck of online test time is broken.

[0041] In other embodiments of the present application, the test device can collect the power of the compressor at the first sampling frequency to obtain power data within the target period, and collect the wind speed at the air outlet of the first chamber at the first sampling frequency to obtain wind speed data. Here, the first sampling frequency and the second sampling frequency can be the same, or the first sampling frequency and the second sampling frequency can be different, as long as the collected test data can indicate the current operating status of the compressor of the refrigeration equipment and the working status of the fan and damper of the refrigeration equipment.

[0042] In other embodiments of the present application, the wind speed data is collected by a wind speed sensing module whose distance from the air outlet of the first chamber is within a distance threshold.

[0043] In the embodiment of the present application, the wind speed sensing module is a sensing module for measuring the wind speed at the air outlet of the first chamber. The wind speed sensing module may be a wind speed sensor. The wind speed sensor outputs the measured wind speed at the air outlet of the first chamber in the form of an electrical signal such as a voltage for the data acquisition module to record. In an application scenario, the wind speed sensor may be a Figure 4 Here, the wind speed sensing module and the data acquisition module can be connected to each other through a wireless transmission module, which can be a WIFI module or a low-power long-range (Long Range, LoRa) module. When the LoRa module transmits signals, the signals are stable and have strong penetration.

[0044] In the embodiment of the present application, the distance threshold can be understood as the range where the wind speed data collected by the wind speed sensor module meets the data required for wind speed collection. Here, the wind speed sensor module can be located on the glass shelf closest to the air outlet of the first room, and the wind speed sensor module can also be located on the door shelf closest to the air outlet of the first room. Of course, the wind speed sensor module can also be located on the glass shelf or door shelf that is the second closest to the air outlet of the first room, as long as the wind speed data collected by the wind speed sensor module meets the wind speed collection requirements. In this way, the accuracy and reliability of the wind speed data are guaranteed, and at the same time, the wind speed sensor module is not damaged and easy to operate.

[0045] It should be noted that in the related art, when the refrigeration equipment is tested online in the factory, the temperature of the refrigeration room is collected by a temperature sensor such as a temperature collection probe, and the temperature collection probe is inserted into the air outlet of the refrigeration room to quickly sense the temperature drop. However, this operation is easy to damage the collection probe and is not easy to operate.

[0046] Step 102: Process the test data and generate performance test results of the refrigeration equipment based on the processed test data.

[0047] In an embodiment of the present application, after the test device is powered on the refrigeration equipment, it responds to the test instruction sent by the main control board of the refrigeration equipment, obtains the test data of the refrigeration equipment within the target time period, processes the power data of the compressor of the refrigeration equipment, processes the wind speed data of the air outlet of the first chamber of the refrigeration equipment, and generates a performance test result of the refrigeration equipment based on the processed power data and the processed wind speed data.

[0048] The test method for refrigeration equipment provided in the embodiment of the present application responds to the test instruction sent by the main control board of the refrigeration equipment after the refrigeration equipment is powered on, and obtains the test data of the refrigeration equipment within the target time period, wherein the test data includes the power data of the compressor of the refrigeration equipment and the wind speed data of the air outlet of the first chamber of the refrigeration equipment; the test data is processed, and the performance test result of the refrigeration equipment is generated according to the processed test data; in this way, by collecting the wind speed of each chamber of the refrigeration equipment and the power of the compressor, it is determined whether the performance of the refrigeration equipment is qualified, which not only avoids the influence of the ambient temperature and the box temperature on the air-cooled refrigeration equipment, but also improves the detection efficiency, improves the production efficiency, and achieves a breakthrough in the bottleneck of the industry.

[0049] The embodiment of the present application provides a test method for a refrigeration device. The test method for the refrigeration device is applied to the test device. Figure 5 As shown, the testing method of the refrigeration equipment includes the following steps:

[0050] Step 201: After the refrigeration device is powered on, respond to a test instruction sent by a main control board of the refrigeration device to obtain test data of the refrigeration device within a target period of time.

[0051] The test data includes power data of a compressor of the refrigeration equipment and wind speed data of an air outlet of a first chamber of the refrigeration equipment.

[0052] Step 202: Perform curve fitting on the power data to obtain a power curve.

[0053] Step 203: Perform curve fitting on the wind speed data to obtain a wind speed curve.

[0054] Step 204: Generate performance test results according to the power curve and the wind speed curve.

[0055] In the embodiment of the present application, after the test device is powered on to the refrigeration device, it responds to the test instruction sent by the main control board of the refrigeration device, obtains the test data of the refrigeration device in the target period, performs curve fitting on the power data of the compressor of the refrigeration device to obtain the power curve; performs curve fitting on the wind speed data of the air outlet of the first chamber of the refrigeration device to obtain the wind speed curve, and generates the performance test result of the refrigeration device according to the power curve and the wind speed curve. Figure 6 As shown, the horizontal axis represents time and the vertical axis represents wind speed. Figure 6 Shown is a schematic diagram of a wind speed curve at an air outlet of a first compartment of a refrigeration device.

[0056] In the present application, refer to Figure 7 As shown, step 204 generates performance test results according to the power curve and the wind speed curve, which can be achieved by the following steps:

[0057] Step 2041: Determine that the power corresponding to each time point in the target time period in the power curve is within the power threshold, and generate a first test result indicating that the refrigeration performance of the refrigeration equipment is qualified.

[0058] In the embodiment of the present application, the power threshold is a power range that represents the normal operation of the compressor.

[0059] Step 2042: Determine that the wind speed corresponding to each time point in the first time period included in the target time period in the wind speed curve is within the first wind speed threshold, and the wind speed corresponding to each time point in the second time period included in the target time period is within the second wind speed threshold, and generate a second test result indicating that the air duct performance of the refrigeration equipment is qualified.

[0060] Among them, the first wind speed threshold is different from the second wind speed threshold, the first time period is a time period for turning on the fan and damper of the refrigeration equipment, and the second time period is a time period for turning off the fan and damper, and the performance test result includes the first test result and the second test result.

[0061] In the embodiment of the present application, the first wind speed threshold is a wind speed range when the fan and damper of the refrigeration device are turned on, and the second wind speed threshold is a wind speed range when the fan and damper of the refrigeration device are turned off.

[0062] In the embodiment of the present application, first, the test device obtains the power corresponding to each time point of the target period in the power curve, and determines whether all the powers are within the power threshold. If the test device determines that all the powers are within the power threshold, a first test result is generated that the refrigeration performance of the refrigeration equipment is qualified. Then, the test device obtains the wind speed corresponding to each time point in the period of turning on the fan and damper of the refrigeration equipment in the wind speed curve, and determines whether all the wind speeds are within the first wind speed threshold. If the test device determines that all the wind speeds are within the first wind speed threshold, the wind speed corresponding to each time point in the period of turning off the fan and damper of the refrigeration equipment in the wind speed curve is further obtained, and it is determined whether all the wind speeds are within the second wind speed threshold. If the test device determines that all the wind speeds are within the second wind speed threshold, a second test result is generated that the air duct performance of the refrigeration equipment is qualified. In this way, by collecting the wind speed of each compartment of the refrigeration equipment, it is determined whether the fan and damper are opened and closed normally; it replaces the existing temperature collection technology, completely solves the influence of ambient temperature and box temperature on air-cooled refrigeration equipment, improves detection efficiency, improves production efficiency, and achieves a breakthrough in industry bottlenecks.

[0063] In the present application, refer to Figure 8 As shown, step 204 generates a performance test result according to the power curve and the wind speed curve, which can also be achieved by the following steps:

[0064] Step 2043: determine that the power corresponding to at least some time points in the power curve is not within the power threshold, and generate a third test result indicating that the refrigeration performance of the refrigeration equipment is unqualified.

[0065] Step 2044, determine that the wind speed corresponding to at least some of the time points in the first time period in the wind speed curve is not within the first wind speed threshold, and / or determine that the wind speed corresponding to at least some of the time points in the second time period in the wind speed curve is not within the second wind speed threshold, and generate a fourth test result indicating that the air duct performance of the refrigeration equipment is unqualified.

[0066] The performance test result includes the third test result and / or the fourth test result.

[0067] In the embodiment of the present application, first, the test device obtains the power corresponding to each time point in the target time period in the power curve, and determines whether all the powers are within the power threshold. If the test device determines that the power corresponding to at least some of the time points is not within the power threshold, a third test result is generated that the refrigeration performance of the refrigeration device is unqualified. Then, the test device obtains the wind speed corresponding to each time point in the time period when the fan and damper of the refrigeration device are turned on in the wind speed curve, and determines whether all the wind speeds are within the first wind speed threshold. If the test device determines that the wind speed corresponding to at least some of the time points is not within the first wind speed threshold, a fourth test result is generated that the air duct performance of the refrigeration device is unqualified. Alternatively, the test device determines that all wind speeds are within the first wind speed threshold, and further obtains the wind speed corresponding to each time point in the time period when the fan and damper of the refrigeration device are turned off in the wind speed curve, and determines whether all the wind speeds are within the second wind speed threshold. If the test device determines that the wind speed corresponding to at least some of the time points is not within the second wind speed threshold, a fourth test result is generated that the air duct performance of the refrigeration device is unqualified.

[0068] It should be noted that when the testing equipment determines that at least one of the refrigeration performance and / or air duct performance of the refrigeration equipment is unqualified, it stops detecting other unfinished test items and outputs a prompt message to indicate that the refrigeration equipment has a fault, which greatly shortens the troubleshooting speed of the refrigeration equipment and improves the efficiency of detecting faulty equipment.

[0069] Step 205: Obtain the equipment identification of the refrigeration equipment.

[0070] In the embodiment of the present application, the device identification is used to identify the identity information of the refrigeration equipment, and the test equipment can read the identification component on the refrigeration equipment through the reading component to obtain the device identification of the refrigeration equipment; here, the identification component can be a barcode pasted on the refrigeration equipment, and the reading component is a barcode scanner; of course, the identification component can also be other components that can store the identity information of the refrigeration equipment, such as a QR code, a radio frequency card, etc., and the reading component is other components that can read the identity information in the identification component, such as a camera equipped with image recognition software, a radio frequency card reader, etc.; this is not specifically described in the present invention.

[0071] Step 206: Generate an association relationship between the device identification and the performance test result of the refrigeration device, and store the association relationship.

[0072] In the embodiment of the present application, after the test device obtains the device identification of the refrigeration device, it generates an association relationship between the device identification and the performance test result of the refrigeration device, and stores the association relationship; thus, it is convenient to track and trace the recorded detection information.

[0073] It should be noted that, for the description of the same steps and the same contents in this embodiment as those in other embodiments, reference can be made to the description in other embodiments and will not be repeated here.

[0074] This application describes a test method for a refrigeration device provided in an implementation scenario. The test method for the refrigeration device is applied to the test device. Fig. 9 As shown, the testing method of the refrigeration equipment includes the following steps:

[0075] Step 301: After the refrigeration device is powered on, the station code of the refrigeration device and the barcode of the refrigeration device are obtained.

[0076] Here, the station code can be understood as the code of the socket to which the refrigeration device is connected, so that the connected socket can complete the testing process of the refrigeration device.

[0077] Step 302: When the test device obtains the station code and the barcode, the power data of the compressor of the refrigeration device and the wind speed data of the air outlet of the first chamber of the refrigeration device within the target time period are obtained.

[0078] Step 303: Perform curve fitting on the power data to obtain a power curve.

[0079] Step 304: Perform curve fitting on the wind speed data to obtain a wind speed curve.

[0080] Step 305: Determine the power performance and air duct performance of the refrigeration equipment according to the power curve and the wind speed curve.

[0081] Here, if the power performance and air duct performance of the refrigeration equipment are determined to be qualified according to the power curve and wind speed curve, the test ends; if the power performance and air duct performance of the refrigeration equipment are determined to be unqualified according to the power curve and wind speed curve, the performance test results are recorded and information for factory return repair is generated. In this way, the wind speed of each room of the refrigeration equipment is collected to determine whether the fan and damper are opened or closed normally; it replaces the existing temperature collection technology, completely solves the impact of ambient temperature and box temperature on air-cooled refrigeration equipment, achieves a breakthrough in industry bottlenecks, improves detection efficiency, and improves production benefits.
