Wherein the lengths of the N first wire harnesses of the first terminal are different from each other, and the lengths of the M second wire harnesses of the second terminal are also different from each other, so that differentiated identifications of physical dimensions are formed, and the possibility of mismatching is limited from the physical level (for example, an overlong wire harness cannot adapt to an interface with an over-short distance, and an overshort wire harness cannot be connected with an interface with a long distance); therefore, the misplug probability is reduced, and the wiring accuracy is improved.

[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0028] In the description of the present application, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second", "third", etc. can be explicitly or implicitly included one or more features.

[0029] In the present application, the word "exemplary" is used to mean "serving as an example, instance, or illustration". Any implementation described as "exemplary" in the present application is not necessarily to be construed as preferred or advantageous over other implementations. The following description is presented to enable any person skilled in the art to make and use the present application. In the following description, for the purpose of explanation, details are set forth. It is apparent to those skilled in the art that the present application can be practiced without using these specific details. In other instances, well-known structures and processes are not described in detail in order to avoid obscuring the description of the present application. Therefore, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

[0030] It should be noted that the method of the present application is executed in a computer device, and the processing objects of each computer device exist in the form of data or information, such as time, which is essentially time information. It can be understood that in subsequent embodiments, if the size, quantity, position, etc. are mentioned, they all exist in the form of corresponding data for processing by the computer device, and specific details are not repeated here.

[0031] Although the current mainstream modular design supports flexible expansion of capacity by multiple unit parallel connection, it is easy to cause misplug problem due to similar physical load interface and adjacent layout of multiple systems. Therefore, the present application provides a heat pump system, a detection method, a detection device and a storage medium. In the heat pump system, by setting the length differentiation of the internal wires of the heat pump unit, the misplug problem in the unit can be reduced, and the wiring accuracy can be improved.

[0032] Please refer to Figure 1 , Figure 1 is a structural schematic diagram of a heat pump system provided by an embodiment of the present application;

[0033] The present application provides a heat pump system 1000, as shown in Figure 1As shown, the heat pump system 1000 includes a first heat pump unit and a second heat pump unit. The first heat pump unit includes a first terminal 100, and the first terminal 100 includes N first wire harnesses with different wire lengths. The second heat pump unit includes a second terminal 200, and the second terminal 200 includes M second wire harnesses with different wire lengths. N and M are both natural numbers greater than 0. Specifically, the values of N and M can be set according to actual needs. Figure 1 For example, N is 5 and M is 4.

[0034] Specifically, as shown, Figure 1 The first terminal 100 further includes a first buckle 170, one end of the first buckle 170 is connected with the N first wire harnesses, and the other end of the first buckle 170 is connected with a device in the first heat pump unit to transmit sensor data of the first heat pump unit. The second terminal 200 further includes a second buckle 270, one end of the second buckle 270 is connected with the M second wire harnesses, and the other end of the second buckle 270 is connected with a device in the second heat pump unit to transmit sensor data of the second heat pump unit. The first buckle 170 is an interface of the first terminal 100 and can be connected with the device in the first heat pump unit. The second buckle 270 is an interface of the second terminal 200 and can be connected with the device in the second heat pump unit.

[0035] In this embodiment, the N first wire harnesses of the first terminal 100 have different wire lengths, and the M second wire harnesses of the second terminal 200 also have different wire lengths, thereby forming a differentiated identification in the physical dimension. As an intuitive physical property, the wire length is not affected by the environment (such as dust and light) or human factors (such as label falling off). The operator can directly distinguish the wire harnesses with different functions through the wire length, thereby limiting the possibility of mismatch from the physical level (for example, a wire harness that is too long cannot be adapted to an interface that is too close, and a wire harness that is too short cannot be connected to a long-distance interface), thereby reducing the probability of misplug and improving the accuracy of wiring.

[0036] In some embodiments, the N first wire harnesses of the first terminal 100 have wire lengths greater than a first lower limit of wire length. Specifically, the first lower limit of wire length can be represented as: L_A = 1.1 x D_A; where L_A represents the first lower limit of wire length, and D_A represents the minimum path from the load of the first heat pump unit to the interface.

[0037] In some embodiments, the M second wire harnesses of the second terminal 200 have wire lengths greater than a second lower limit of wire length. Specifically, the second lower limit of wire length can be represented as: L_B = 0.9 x D_B + AL; where L_B represents the second lower limit of wire length, D_B represents the minimum path from the load of the second heat pump unit to the interface, and AL represents a physical foolproof distance length (for example, 500 mm).

[0038] In some embodiments, for the wire harnesses with the same wire color in the N first wire harnesses, the difference in wire length exceeds a first preset threshold; for the wire harnesses with the same wire color in the M second wire harnesses, the difference in wire length exceeds a second preset threshold. In this embodiment, when the wire harnesses are the same color, the visual distinction is greatly reduced, which can easily become a high-risk scenario for misplugging (for example, wire harnesses of the same color may correspond to interfaces with different functions, but operators are easily confused due to the consistency of color). The design in which the wire length difference exceeds the preset threshold uses a significant physical length difference instead of color as the core distinguishing mark. Even if the colors are exactly the same, the length difference of the wire harnesses is obvious enough. The operator can quickly distinguish them through intuitive visual comparison or hand-held feeling (such as when picking up the wire harness, the overlong part will naturally droop), eliminating the recognition ambiguity caused by the same color from a physical level.

[0039] In some embodiments, both the first preset threshold and the second preset threshold need to exceed the operator's arm extension tolerance, for example, greater than 500mm. When the operator is connecting wires, there is a natural physiological limit to the arm extension range (i.e., the arm extension tolerance). For example, when a wire harness only needs to connect to an interface 1000mm away, and another wire harness of the same color is 1600mm long, the difference in wire length is 600mm. If a long wire harness is mistakenly used to connect a short-distance interface, the excessively long part will form a "redundant obstruction" because the arm cannot be overextended, such as the wire harness dragging on the ground, entangled, or requiring deliberate pulling to barely connect, resulting in obvious operational discomfort; on the contrary, when a short wire harness is used to connect a long-distance interface, the interface will not be reached at all due to insufficient length.

[0040] For example, Figure 4 As shown, the first terminal 100 includes a first wire harness 111 with black wire color and a wire length of L1, a first wire harness 112 with white wire color and a wire length of L2, a first wire harness 113 with red wire color and a wire length of L3, a first wire harness 114 with black wire color and a wire length of L4, and a first wire harness 115 with black wire color and a wire length of L5. Among them, L1 can be 2000 mm, L2 can be 2100 mm, L3 can be 2200 mm, L4 can be 3000 mm, and L5 can be 1400 mm.

[0041] like Figure 5 As shown, the second terminal 200 includes a second wire harness 211 with black wire color and a wire length of L6, a second wire harness 212 with white wire color and a wire length of L7, a second wire harness 213 with red wire color and a wire length of L8, and a first wire harness 214 with black wire color and a wire length of L9. Among them, L6 can be 2000mm, L7 can be 2200mm, L8 can be 1800mm, and L9 can be 3000mm.

[0042] In some embodiments, the first terminal 100 includes a first buckle 170 and 2N first pins, with each two first pins corresponding to a first wiring harness. The second terminal 200 also includes a second buckle 270 and 2M second pins, with each two second pins corresponding to a second wiring harness. The first buckle and the second buckle are different colors, and N and M are not equal.

[0043] For example, Figure 2 As shown, Figure 2 In the example where N is 5, the first terminal 100 includes a first buckle 170, 5 first wiring harnesses, and 10 first pins. The first terminal 100 specifically includes: a first buckle 170, a first wiring harness 111, a first wiring harness 112, a first wiring harness 113, a first wiring harness 114, a first wiring harness 115, a first pin 161, a first pin 162, a first pin 163, a first pin 164, a first pin 165, a first pin 166, a first pin 167, a first pin 168, a first pin 169, and a first pin 1610. Figure 2 , the first pin 161 and the first pin 162 are correspondingly connected to the first wiring harness 111, the first pin 163 and the first pin 164 are correspondingly connected to the first wiring harness 112, the first pin 165 and the first pin 166 are correspondingly connected to the first wiring harness 113, the first pin 167 and the first pin 168 are correspondingly connected to the first wiring harness 114, and the first pin 169 and the first pin 1610 are correspondingly connected to the first wiring harness 115.

[0044] For example, Figure 3 As shown, Figure 3 In the example where N is 4, the second terminal 200 includes a second buckle 270, four second wiring harnesses, and eight second pins. The first terminal 100 specifically includes: a second buckle 270, a second wiring harness 211, a second wiring harness 212, a second wiring harness 213, a second wiring harness 214, a second pin 261, a second pin 262, a second pin 263, a second pin 264, a second pin 265, a second pin 266, a second pin 267, and a second pin 268. Figure 3 , the second pin 261 and the second pin 262 are connected to the second wiring harness 211 , the second pin 263 and the second pin 264 are connected to the second wiring harness 212 , the second pin 265 and the second pin 266 are connected to the second wiring harness 213 , and the second pin 267 and the second pin 268 are connected to the second wiring harness 211 .

[0045] In this embodiment, the first and second buckles are set to different colors to facilitate differentiation between the first and second terminals. By setting N and M to be unequal, for example, N is 5 and M is 4, the number of wire harnesses of the first and second terminals is different, further facilitating differentiation between the first and second terminals.

[0046] In some embodiments, the first terminal 100 further includes N first sensors, at least one of which is a preset sensor; wherein the plastic cover of the first sensor that is a preset sensor has a different diameter than the plastic cover of the first sensor that is a non-preset sensor. The second terminal 200 further includes M second sensors, at least one of which is a preset sensor; wherein the plastic cover of the second sensor that is a preset sensor has a different diameter than the plastic cover of the second sensor that is a non-preset sensor.

[0047] The sensor types include exhaust temperature sensor, return air temperature sensor, outer pipe temperature sensor, outer ring temperature sensor, refrigerant liquid pipe temperature sensor, subcooling outlet temperature sensor, refrigerant gas pipe temperature sensor, water inlet sensor, water outlet sensor, etc. The default sensor is the exhaust temperature sensor.

[0048] In some embodiments, the diameter of the plastic cover of a first sensor that is a preset sensor can be set to 6 mm, while the diameter of the plastic cover of a first sensor that is a non-preset sensor can be set to 5 mm. The diameter of the plastic cover of a second sensor that is a preset sensor can be set to 6 mm, while the diameter of the plastic cover of a second sensor that is a non-preset sensor can be set to 5 mm.

[0049] For example, Figure 2 As shown, the first terminal 100 includes five first sensors, specifically including: a first sensor 121 connected to the first wiring harness 111, a first sensor 122 connected to the first wiring harness 112, a first sensor 123 connected to the first wiring harness 113, a first sensor 124 connected to the first wiring harness 114, and a first sensor 125 connected to the first wiring harness 115. The first terminal 100 also includes a plastic head 131 of the first sensor 121, a plastic head 132 of the first sensor 122, a plastic head 133 of the first sensor 123, a plastic head 134 of the first sensor 124, and a plastic head 135 of the first sensor 125. Among them, the plastic heads 131, 132, 133 and 134 are all copper heads, and the plastic head 135 is a water drop head. As shown Figure 6 As shown, the diameter of plastic head 131 is d1, the diameter of plastic head 132 is d2, the diameter of plastic head 133 is d3, and the diameter of plastic head 134 is d4. If first sensor 121 is an exhaust temperature sensor and the remaining first sensors are not exhaust temperature sensors, the diameter d1 of plastic head 131 can be set to 6 mm, and the diameters of the remaining copper heads can be set to 5 mm.

[0050] like Figure 3As shown, the second terminal 200 includes four first sensors, specifically including: a second sensor 221 connected to the second wiring harness 211, a second sensor 222 connected to the second wiring harness 212, a second sensor 223 connected to the second wiring harness 213, and a second sensor 224 connected to the second wiring harness 214; the second terminal 200 also includes a plastic head 231 of the second sensor 221, a plastic head 232 of the second sensor 222, a plastic head 233 of the second sensor 223, and a plastic head 234 of the second sensor 224. Among them, the plastic heads 231, 232, and 233 are all copper heads, and the plastic head 234 is a water drop head. Figure 7 As shown, the diameter of plastic head 231 is d5, the diameter of plastic head 232 is d6, and the diameter of plastic head 234 is d3. If second sensor 221 is an exhaust temperature sensor and the remaining second sensors are not exhaust temperature sensors, the diameter d5 of plastic head 231 can be set to 6 mm, and the diameters of the plastic heads of the remaining copper heads can be set to 5 mm.

[0051] In this embodiment, by differentiating the plastic sealing head of the exhaust temperature sensor from the other plastic sealing heads, it is possible to prevent the exhaust temperature sensor from being mistakenly plugged into the sockets of other sensors, thereby reducing the probability of misplugging and improving the accuracy of wiring.

[0052] In the heat pump system 1000 provided in the embodiment of the present application, the N first wiring harnesses of the first terminal 100 are configured with different lengths, and the M second wiring harnesses of the second terminal 200 are configured with different lengths, thereby forming a physically differentiated identifier. As an intuitive physical property, wire length is unaffected by environmental or human factors. Operators can directly distinguish wire harnesses with different functions by wire length, which physically limits the possibility of mismatching, thereby reducing the probability of misplugging and improving wiring accuracy.

[0053] Second, as Figure 8 As shown, the embodiment of the present application further provides a detection method for detecting the above-mentioned heat pump system, and the detection method includes the following steps S1 to S6:

[0054] Step S1: Control the first heat pump unit and the second heat pump unit to operate according to a first preset rule to obtain first operating information.

[0055] In this embodiment, the first operation information includes sensor data of the first heat pump unit and the second heat pump unit operating according to the first preset rule.

[0056] In some embodiments, the first heat pump unit and the second heat pump unit are controlled to operate according to a first preset rule to obtain first operating information, including: controlling the first heat pump unit and the second heat pump unit to operate in standby mode; controlling the first heat pump unit to operate in heating mode after a first preset time of standby mode; during the heating mode of the first heat pump unit, setting the main valve opening, auxiliary valve opening, fan target speed, and compressor set frequency of the first heat pump unit according to the first preset rule; and collecting information during the heating mode of the first heat pump unit to obtain first operating information.

[0057] The first preset time can be set according to actual needs, for example, it can be set to 20s, 40s, etc.

[0058] In this embodiment, during the heating operation of the first heat pump unit, the main valve opening, auxiliary valve opening, fan target speed, and compressor setting frequency of the first heat pump unit are set according to the first preset rule, specifically: the main valve opening of the first heat pump unit is set to 250P, the auxiliary valve opening of the first heat pump unit is set to 0P, the fan target speed of the first heat pump unit is set to 400rpm, and the compressor setting frequency of the first heat pump unit is set to 60Hz.

[0059] Step S2: determining whether the first heat pump unit and the second heat pump unit are installed reversely based on the first operating information.

[0060] In this embodiment, the method for determining whether the first heat pump unit and the second heat pump unit are installed reversely based on the first operating information may include: if the sensor data of the first heat pump unit is not obtained in the first operating information, and the sensor data of the second heat pump unit is obtained in the first operating information, then determining that the first heat pump unit and the second heat pump unit are installed reversely; if the sensor data of the first heat pump unit is obtained in the first operating information, and the sensor data of the second heat pump unit is not obtained in the first operating information, then determining that the first heat pump unit and the second heat pump unit are not installed reversely.

[0061] Step S3: When it is determined that the first heat pump unit and the second heat pump unit are not installed reversely, the first heat pump unit is controlled to operate according to a second preset rule to obtain second operating information.

[0062] The second operation information includes sensor data of the first heat pump unit during operation according to the second operation rule.

[0063] In some embodiments, the first heat pump unit is controlled to operate according to a second preset rule to obtain second operation information, including: controlling the first heat pump unit to operate in a cooling mode; setting the main valve opening degree, the auxiliary valve opening degree, the fan target rotating speed, and the compressor set frequency of the first heat pump unit according to the second preset rule during the cooling operation of the first heat pump unit; and collecting information during the cooling operation of the first heat pump unit to obtain the second operation information.

[0064] In this embodiment, the main valve opening degree, the auxiliary valve opening degree, the fan target rotating speed, and the compressor set frequency of the first heat pump unit are set according to the second preset rule during the cooling operation of the first heat pump unit, which can specifically include: in a first time period (for example, a time period of 0S-120S during the cooling operation), the main valve opening degree of the first heat pump unit is set to 350P, the auxiliary valve opening degree of the first heat pump unit is set to 0P, the fan target rotating speed of the first heat pump unit is set to 500rpm, and the compressor set frequency of the first heat pump unit is set to 60Hz; then, in a second time period (for example, a time period of 120S-220S during the cooling operation), the main valve opening degree of the first heat pump unit is set to 350P, the auxiliary valve opening degree of the first heat pump unit is set to 80P, the fan target rotating speed of the first heat pump unit is set to 500rpm, and the compressor set frequency of the first heat pump unit is set to 80Hz.

[0065] Step S4: determining a first fault detection result of the first heat pump unit based on the first operation information and the second operation information.

[0066] The first fault result includes: whether the inlet and outlet water sensors are inserted incorrectly; whether the main and auxiliary refrigerant sensors are installed reversely; whether there is a cooling fault; and whether there is a heating fault. Whether the inlet and outlet water sensors are inserted incorrectly refers to whether the inlet water sensor and the outlet sensor are inserted incorrectly. Whether the main and auxiliary refrigerant sensors are installed reversely refers to whether the main refrigerant sensor and the auxiliary refrigerant sensor are installed reversely.

[0067] In this embodiment, the first operation information collected during the heating operation of the first heat pump unit is compared with the second operation information collected during the cooling operation of the first heat pump unit, so as to determine whether the inlet water sensor of the first heat pump unit and the outlet water sensor of the first heat pump unit are inserted incorrectly. During the cooling operation of the first heat pump unit, the auxiliary valve opening degree is switched from 0P to 80P, so as to determine whether the main refrigerant sensor of the first heat pump unit and the auxiliary refrigerant sensor of the first heat pump unit are installed reversely. Whether there is a heating fault is determined based on the first operation information and the heating fault condition. Whether there is a cooling fault is determined based on the second operation information and the cooling fault condition.

[0068] The heating fault condition is used to determine whether there is a heating fault, and the cooling fault condition is used to determine whether there is a cooling fault.

[0074] In the process of the second heat pump unit in the refrigeration operation, the main valve opening degree, the auxiliary valve opening degree, the fan target rotating speed, and the compressor set frequency of the second heat pump unit are set according to the third preset rule, which can specifically include: in the first time period (for example, the time period of 0S-120S of the refrigeration operation), the main valve opening degree of the second heat pump unit is set to 350P, the auxiliary valve opening degree of the second heat pump unit is set to 0P, the fan target rotating speed of the second heat pump unit is set to 500rpm, and the compressor set frequency of the second heat pump unit is set to 60Hz; then, in the second time period (for example, the time period of 120S-220S of the refrigeration operation), the main valve opening degree of the second heat pump unit is set to 350P, the auxiliary valve opening degree of the second heat pump unit is set to 80P, the fan target rotating speed of the second heat pump unit is set to 500rpm, and the compressor set frequency of the second heat pump unit is set to 80Hz.
