Description

Technical Field

[0001] The present application relates to the technical field of device detection, and in particular to a device detection method, apparatus, electronic device, storage medium and program product. Background Art

[0002] For heating products, the water system usually uses a plate heat exchanger to achieve heat exchange between the refrigerant and water to ensure effective heat transfer and high efficiency of system operation. In order to ensure the reliability and stability of the equipment in actual operation, the whole machine detection process needs to increase the load and pass water to verify the normal start-up of the electronic control system and the PFC (Power Factor Correction) function. In addition, the whole machine detection process is also used to confirm the correct plug-in of various sensors to avoid system failures caused by the wrong insertion of sensors.

[0003] However, in actual operation, due to the problem of residual water inside the system during the detection process, the water in the expansion tank and water pump often cannot be drained by blowing. These residual water will easily cause rust and verdigris formation on the copper tubes, corrosion of the shielding sleeve and impeller, and even impeller jam during long-term storage, especially inside the copper tubes and plate heat exchangers. What's more serious is that the residual water may seep out during transportation, causing the packaging materials and wooden frames to soak and mold, affecting the packaging quality and the overall appearance of the product. Therefore, it is necessary to dry the residual water inside the system during the detection process, but drying takes a lot of time, which reduces the detection efficiency of heating products.

[0025] The following is a further detailed description of the implementation of the present application in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application but cannot be used to limit the scope of the present application.

[0026] In the description of the embodiments of the present application, it should be noted that the terms "first", "second" and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0027] In the embodiments of the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0028] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiments of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0029] In the related art, during the inspection process of heating products, if the pipe leaks, that is, there is a leak at the pipe connection, the inspection process will be inaccurate. After the product is inspected, it is necessary to drain the residual moisture by blowing and drying. If the protection during the blowing and drying process is insufficient, the residual moisture may cause the wooden frame to be soaked in water, causing mold and easy damage. In addition, since the pipe connection, water supply and blowing and drying processes are time-consuming, the inspection and production efficiency of heating products are affected. On the other hand, the heating product inspection system lacks constant temperature equipment. When multiple machines are inspected at the same time, the water temperature and water flow fluctuate frequently, resulting in a large fluctuation range of the inspection parameters, which may lead to misjudgment. In an open water system, the continuous operation of the external large water pump also makes it difficult to verify the working condition of the built-in water pump, which further affects the product inspection and verification process.

[0030] Based on the above problems, this application proposes an equipment detection method, which aims to solve the problem of residual water in the water system of heating products, and to solve the problem of water failure in the water system of products; to achieve the purpose of detection by idling heat exchange without medium in heating and cooling machines, that is, in the detection process, no actual heat medium (such as water or coolant) is used, but the detection is completed by idling (i.e. no-load operation), which can avoid inaccurate detection caused by medium problems and reduce the complexity of maintenance and processing. At the same time, it can also realize the detection of the machine in a short running time, improve the detection efficiency, and eliminate the detection pipe connection, water flow, and air drying processes. In addition, since the short detection process can reduce the load and complexity of the equipment in operation, the oil return of the compressor and the machine protection shutdown can be avoided.

[0031] Figure 1 Schematic diagram of the device detection method provided in the embodiment of the present application. Figure 1 , the present application embodiment provides a device detection method, including: Step 101, sending a detection instruction to a heating product.

[0032] The execution subject of the embodiment of the present application is a host computer, which refers to a computer system or controller used to control and monitor equipment. Heating products refer to equipment used to heat space, such as radiators, floor heating systems or other heaters. The host computer is connected to the heating product. During the detection of the heating product, the host computer tests the performance of the heating product by controlling different modes of the heating product (such as heating or cooling) and records various operating parameters. If the heating product fails or is abnormal, the host computer reports the corresponding error code.

[0033] During the heating product detection process, the host computer sends a detection instruction to the heating product, wherein the detection instruction is used to instruct the heating product to respectively operate the working mode corresponding to each set time period in multiple set time periods. After receiving the detection instruction sent by the host computer, the heating product enters the factory detection mode, and then operates in sequence according to each set time period and its corresponding working mode, for example, operating the cooling mode, heating mode and cooling mode in sequence.

[0034] Step 102, recording the operating parameters of the heating product in each of the set time periods.

[0035] In an embodiment of the present application, the set time period includes a first set time period, a second set time period, a third set time period and a fourth set time period; wherein the working mode corresponding to the first set time period is the cooling mode; the working mode corresponding to the second set time period is the cooling mode and the compressor of the heating product is turned on; the working mode corresponding to the third set time period is the heating mode; and the working mode corresponding to the fourth set time period is the cooling mode.

[0036] Heating products include components such as compressors, water pumps, plate heat exchangers and fin heat exchangers. Among them, the plate heat exchanger is a device that uses a series of metal plates for heat exchange. It is used for heat transfer between liquids and has a compact design and efficient heat exchange performance; the fin heat exchanger is a device that increases the heat exchange efficiency by increasing the surface area by attaching fins to the pipe. It is used for heat transfer between air and liquid.

[0037] Record the operating parameters of the heating product in each set time period, including: (1) Record the first set of operating parameters of the heating product within the first set time period. That is, record the operating parameters of the heating product in the cooling mode. The first set of operating parameters includes the exhaust temperature Tp of the compressor, the return air temperature Th of the compressor, the outlet temperature T3 of the fin heat exchanger, the outdoor ambient temperature T4, the refrigerant liquid side temperature T2 of the plate heat exchanger, the refrigerant gas side temperature T2b of the plate heat exchanger, the outlet water temperature Twout of the plate heat exchanger, the inlet water temperature Twin of the plate heat exchanger, the power Pwp of the water pump, the module problem Tf, the opening degree PMV of the electronic expansion valve and the whole machine power P1 parameters, etc. Figure 2As shown, Figure 2 The black squares in the middle indicate the device locations of the temperature sensors of the fluorine system. These temperature sensors are used to detect the exhaust temperature Tp, the return air temperature Th, the outdoor ambient temperature T4 and the outlet temperature of the fin heat exchanger.

[0038] (2) Recording a second set of operating parameters of the heating product within a second set time period. That is, recording the operating parameters of the heating product running in cooling mode with the compressor turned on.

[0039] (3) Recording a third set of operating parameters of the heating product within a third set time period. That is, recording the operating parameters of the heating product in the heating mode.

[0040] (4) Recording the fourth set of operating parameters and the fifth set of operating parameters of the heating product within the fourth set time period. That is, at different time points, record the operating parameters of the heating product in the cooling mode. The fourth set of operating parameters is the operating parameters recorded when the heating product switches from the heating mode to the cooling mode, and the fifth set of operating parameters is the operating parameters recorded when the heating product stably operates in the cooling mode.

[0041] Among them, the second group of operating parameters, the third group of operating parameters, the fourth group of operating parameters and the fifth group of operating parameters all include the exhaust temperature Tp of the compressor, the return air temperature Th of the compressor, the outlet temperature T3 of the fin heat exchanger, the outdoor ambient temperature T4, the refrigerant liquid side temperature T2 of the plate heat exchanger, the refrigerant gas side temperature T2b of the plate heat exchanger, the outlet water temperature Twout of the plate heat exchanger, the inlet water temperature Twin of the plate heat exchanger, the command frequency, the operating frequency, the fan speed, the module problem Tf, the opening of the electronic expansion valve PMV, the whole machine power P1 parameter, the AC current AC_current, the DC current DC_current, the AC voltage AC_Vol, the DC voltage DC_Vol, the actual operating power and the actual operating current, the power factor, etc. Figure 3 As shown, from Figure 3 The device positions of the water-plate heat exchanger temperature sensors can be seen in the figure. These temperature sensors are used to detect the refrigerant liquid side temperature T2, the refrigerant gas side temperature T2b, the outlet water temperature Twout and the inlet water temperature Twin.

[0042] In one embodiment, the steps for detecting a heating product are as follows: 1. The host computer sends a detection command to the heating product, and the main board of the heating product immediately enters the factory detection mode after receiving the detection command; 2. After the heating product receives the detection signal, it immediately turns on the compressor heating belt and turns it off after running for 10 seconds; 3. After 20 seconds, the outdoor unit runs in cooling mode, turns on the fan, and sets the wind speed to level 2. At this time, the host computer records the first set of operating parameters; 4. After 60 seconds, the compressor is turned on, and the target operating frequency is 30Hz. At this time, the host computer records the second set of operating parameters; 5. After 80 seconds, the four-way valve is powered, the outdoor unit runs in heating mode, the compressor operating frequency remains at 30Hz, and the fan speed remains at W6. At this time, the host computer records the third set of operating parameters; 6. After 100 seconds, the four-way valve loses power, the outdoor unit runs in cooling mode, the compressor target operating frequency is 62Hz, and the fan speed is set to W10. At this time, the host computer records the fourth set of operating parameters; 7. After 150 seconds, turn off the compressor. At this time, the host computer records the fifth set of operating parameters between 100-150 seconds; 8. After 165 seconds, turn off the fan; 10. After 180s, exit the factory test mode; 11. When the fan is turned on, all PFCs are started synchronously.

[0043] Step 103, determining the detection result of the heating product according to each of the operating parameters.

[0044] After recording the operating parameters of the heating product in each set time period, the detection result of the heating product is determined according to each operating parameter. For example, each operating parameter is compared with its corresponding set threshold. If the operating parameter does not meet the set threshold, the host computer will automatically report an error, and the fault code will be displayed on the detection host computer.

[0045] In one embodiment, the heating product has self-checking functions such as sensor missing plug-in and communication anomaly detection. Sensor missing plug-in means that the sensor is not correctly connected to the interface of the device. The sensor is used to monitor various parameters of the device (such as temperature and pressure). If the sensor is not correctly connected, the device cannot obtain accurate data, which may cause abnormal operation. Communication anomaly means that there is a problem in the communication between the device and other components (such as sensors or control modules), and data cannot be transmitted normally.

[0046] After the heating product performs self-tests such as sensor missing or communication anomalies, the machine reports a fault and uploads the fault code to the detection host computer, which then displays the received fault code synchronously. For example, if the heating product is equipped with multiple sensors to monitor the temperature of the room, if one of the temperature sensors is not connected correctly, the device's self-test system will find this problem, and the device will automatically generate a fault code (such as "E01" for a sensor connection problem) and send this fault code to the host computer. After receiving this fault code, the host computer will display the "E01" fault code in real time and remind the operator that there is a problem with the sensor.

[0047] The machine stops going to the next step of detection after reporting a fault. It is understandable that the machine will stop the subsequent self-check or operation steps after discovering that the sensor is not plugged in or the communication is abnormal. The purpose of this is to avoid continuing the detection or operation when the fault is not resolved, so as to prevent damage to the equipment or generate erroneous data.

[0048] Through real-time detection and feedback mechanisms, the device can promptly identify and report problems when a sensor is missing or communication is abnormal, and prevent further operations that may cause errors. This not only protects the device itself, but also improves the efficiency of detection and maintenance, ensuring the normal operation of the equipment.

[0049] In one embodiment, it is necessary to detect the compressor heating belt and antifreeze heating belt of the heating product, for example, to detect the parameter Pck1 of the compressor heating belt and the parameter Pck2 of the antifreeze heating belt. If Pck1 is less than the corresponding judgment parameter of the model, the host computer will automatically report an error, such as the host computer reporting an "F2" fault, and the fault code is displayed on the detection host computer, where the "F2" fault indicates that the compressor heating belt detects abnormal power. If Pck2 is less than the corresponding judgment parameter of the model, the host computer will automatically report an error, such as the host computer reporting an "F3" fault, and the fault code is displayed on the detection host computer. Wherein, the "F3" fault indicates that the antifreeze heating belt detects abnormal power.

[0050] The detection and error code mechanism helps ensure the normal operation of the heating belt and prevents equipment problems caused by heating belt failure. The equipment monitors in real time and provides error codes when abnormalities occur, making it easy to quickly locate problems and perform maintenance.

[0051] The equipment detection method provided in the embodiment of the present application sends a detection instruction to the heating product; the detection instruction is used to instruct the heating product to run the working mode corresponding to each set time period in multiple set time periods; record the operating parameters of the heating product in each set time period; and determine the detection result of the heating product based on each operating parameter. The present application eliminates the processes of pipe connection, water supply, air drying, etc. by detecting without water flow, and avoids the influence of water temperature and water flow on detection, thereby improving the detection efficiency and detection accuracy of heating products.

[0052] Based on the above embodiment, determining the detection result of the heating product according to each of the operating parameters includes: Step 1030, determining, based on the first set of operating parameters, a first temperature difference between the outdoor ambient temperature and the outlet temperature of the fin heat exchanger in the heating product, a second temperature difference between the refrigerant gas side temperature of the plate heat exchanger in the heating product and the refrigerant liquid side temperature of the plate heat exchanger, a third temperature difference between the inlet water temperature of the plate heat exchanger and the outlet water temperature of the plate heat exchanger, and the power of the water pump; Step 1031, if the first temperature difference is greater than or equal to the first set temperature difference, or the second temperature difference is greater than or equal to the first set temperature difference, or the third temperature difference is greater than or equal to the first set temperature difference, it is determined that the heating product is abnormal; Step 1032: If the power of the water pump is less than the first set power, it is determined that the power of the water pump is abnormal.

[0053] According to the first set of operating parameters, determine the first temperature difference between the outlet temperature T3_1 of the fin heat exchanger and the outdoor ambient temperature T4_1, i.e., T3_1-T4_1; the second temperature difference between the refrigerant gas side temperature T2b_1 and the refrigerant liquid side temperature T2_1 of the plate heat exchanger, i.e., T2b_1-T2_1; the third temperature difference between the inlet water temperature Twin and the outlet water temperature Twout of the plate heat exchanger, i.e., Twin_1-Twout_1; and the power Pwp of the water pump.

[0054] Then, the calculated temperature differences are compared with the first set temperature difference (such as 10 degrees Celsius). If the first temperature difference is greater than or equal to the first set temperature difference, or the second temperature difference is greater than or equal to the first set temperature difference, or the third temperature difference is greater than or equal to the first set temperature difference, it is determined that the heating product is abnormal. At the same time, the power of the water pump is compared with the first set power. If the power of the water pump is less than the first set power, it is determined that the power of the water pump is abnormal.

[0055] For example, if T3_1-T4_1≥10, the host computer will automatically report an error, such as the host computer reporting an "F4" fault, and the fault code is displayed on the detection host computer. Among them, the "F4" fault indicates that there is an abnormality in the heating product, such as a large temperature difference between the outdoor ambient temperature and the outlet temperature of the fin heat exchanger.

[0056] If T2b_1-T2_1≥10, the host computer will automatically report an error, such as reporting an "F5" fault, which is displayed on the detection host computer. Among them, the "F5" fault indicates that there is an abnormality in the heating product, such as a large temperature difference between the refrigerant gas side temperature and the refrigerant liquid side temperature of the plate heat exchanger.

[0057] If Twin_1-Twout_1≥10, the host computer will automatically report an error, such as the host computer reporting "F6" fault, which is displayed on the detection host computer. Among them, "F6" fault indicates that there is an abnormality in the heating product, such as the temperature difference between the inlet and outlet water temperatures of the plate heat exchanger is too large.

[0058] If the water pump Pwp is less than the corresponding judgment power of the right model (i.e. the first set power), the host computer will automatically report an error, such as reporting an "F7" fault, which is displayed on the detection host computer. Among them, the "F7" fault indicates that the water pump detection power is abnormal.

[0059] In the embodiment of the present application, the host computer and the mainboard of the heating product are interconnected and interacted. During the entire detection process, if the machine reports a fault, the fault code is transmitted to the host computer, and the host computer reports the fault synchronously and records it for later query. At the same time, based on the fault code, the host computer can help technicians quickly locate the problem, reduce the trial and error time in the troubleshooting process, and improve the efficiency of fault repair.

[0060] Based on the above embodiment, determining the detection result of the heating product according to each of the operating parameters includes: Step 1033, obtaining a second whole machine power and power factor of the heating product from the second set of operating parameters; Step 1034, if the quotient of the first whole machine power and the second whole machine power in the first set of operating parameters is less than or equal to a first set threshold, it is determined that the operating power of the heating product is abnormal; Step 1035: If the power factor is less than or equal to the second set threshold, it is determined that the overall power factor verification of the heating product is abnormal.

[0061] The first whole machine power P1_1 of the heating product is obtained from the first set of operating parameters, and the second whole machine power P1_2 and the power factor of the heating product are obtained from the second set of operating parameters, wherein the power factor is the ratio of the active power to the apparent power of the heating product.

[0062] Calculate the quotient of the first whole machine power P1_1 and the second whole machine power P1_2, that is, P1_1÷P1_2, and compare the quotient with the first set threshold (such as 1.1). If P1_1÷P1_2≤1.1, the host computer will automatically report an error, such as the host computer reporting an "F8" fault, and the fault code is displayed on the detection host computer. Among them, the "F8" fault indicates abnormal operating power, such as abnormal operating power of the whole machine and refrigeration operating power.

[0063] When the fan is running and the PFC channel is fully open, the host computer monitors the power factor and compares the monitored power factor with the second set threshold (such as 0.9). If the power factor is ≤0.9, the host computer will automatically report an error. For example, if the host computer reports an "F1" fault, the fault code will be displayed on the detection host computer. Among them, the "F1" fault indicates that the power factor check of the entire machine is abnormal.

[0064] In the embodiment of the present application, the host computer and the mainboard of the heating product are interconnected and interacted. During the entire detection process, if the machine reports a fault, the fault code is transmitted to the host computer, and the host computer reports the fault synchronously and records it for later query. At the same time, based on the fault code, the host computer can help technicians quickly locate the problem, reduce the trial and error time in the troubleshooting process, and improve the efficiency of fault repair.

[0065] Based on the above embodiment, determining the detection result of the heating product according to each of the operating parameters includes: Step 1036, obtaining a third complete machine power of the heating product from the third set of operating parameters, and determining a fourth temperature difference between the exhaust temperature of the compressor and the return air temperature of the compressor; Step 1037, if the quotient of the second whole machine power in the second set of operating parameters and the third whole machine power is less than or equal to a third set threshold, it is determined that the operating power of the heating product is abnormal; Step 1038: If the fourth temperature difference is less than or equal to the second set temperature difference, it is determined that there is an abnormality in the heating product.
