Based on the hardware structure shown in fig. 1, a first embodiment of the present invention provides a fault detection method for an air conditioner.
The method is applied to an air conditioner detector, main components of the air conditioner detector are shown in figure 2, and figure 2 is a schematic composition diagram of the air conditioner detector related to each embodiment of the invention. The air conditioner detector comprises a physical connection unit which can be connected with various types of air conditioners, and specifically, the physical connection unit can be a connection line and/or a connection line interface, such as a display connection line and/or a display connection line interface which is connected with a display in the air conditioner, a controller connection line and/or a control connection line interface which is connected with a centralized controller of the central air conditioner, and an indoor and outdoor unit communication line and/or an indoor and outdoor unit communication line interface which is connected with an outdoor unit or an outdoor unit of a split air conditioner. The connecting line and/or the connecting line interface can be connected to a corresponding component or connecting line of the air conditioner. Thus, physical connection with the air conditioner to be detected can be achieved.

In addition, the air conditioner detector also comprises a function key. The function keys comprise up, down, left and right direction keys, a determination key, an on/off key and the like.
Based on the composition of the air conditioner detector, the fault detection method of the air conditioner is provided.
Referring to fig. 3, fig. 3 is a flowchart illustrating a fault detection method of an air conditioner according to a first embodiment of the present invention. The fault detection method of the air conditioner comprises the following steps:
step S101: after being connected with an air conditioner to be detected through a physical connection unit, sending an analog signal to the air conditioner to be detected so as to test the air conditioner to be detected;
before the air conditioner to be detected is subjected to fault detection, the air conditioner to be detected needs to be connected. And the air conditioner which is not provided with the WIFI or the Bluetooth module is connected with the air conditioner through a signal wire.
Generally, an indoor unit and an outdoor unit of a split type air conditioner are connected through an indoor and outdoor unit communication line, and transmit signals through the communication line. Therefore, for the split air conditioner, after the split air conditioner is connected with the outdoor unit of the air conditioner to be detected through the indoor and outdoor unit communication line or the indoor and outdoor unit communication interface in the physical connection unit, the air conditioner detector simulates the indoor unit at the moment, and sends a corresponding first analog signal to the outdoor unit of the air conditioner to be detected, so that the outdoor unit of the air conditioner to be detected tries to operate after receiving the first analog signal. The first analog signal can be a power-on notice, a target rotating speed of an outdoor fan, a target frequency of an outdoor motor and the like.
After the indoor unit of the air conditioner to be detected is connected with the indoor unit of the air conditioner to be detected through the indoor and outdoor unit communication line or the indoor and outdoor unit communication interface in the physical connection unit, the air conditioner detector simulates the outdoor unit at the moment and sends a second analog signal to the indoor unit of the air conditioner to be detected, so that the indoor unit of the air conditioner to be detected can test and run after receiving the second analog signal. The second analog signal may be a current rotation speed of the outdoor fan, an outdoor temperature, and the like.
Further, the air conditioner detector also comprises a display. And the air conditioner generally has a display connecting line, so that the air conditioner can be connected with a display unit on an indoor main board through a display connecting line or a display connecting line interface in a physical connecting unit, so as to display the current operating parameters of the outdoor unit on the display.
And for the central air conditioner, after the central air conditioner is connected with the outdoor unit or the indoor extension of the air conditioner to be detected through the controller connecting line and/or the control connecting line interface in the physical connecting unit, the air conditioner detector simulates the integrated controller of the central air conditioner at the moment and sends a third analog signal to the outdoor unit or the indoor extension of the air conditioner to be detected. The third analog signal may be a set temperature, a set wind speed, or the like, so that the outdoor unit or the indoor fan tries to operate after receiving the third analog signal.
Step S102: determining a fault machine according to a test operation result, and acquiring operation parameters of the fault machine;
in this embodiment, for the split air conditioner, when the air conditioner detector simulates to be connected with the outdoor unit of the air conditioner to be detected and simulates the indoor unit, if the outdoor unit is normally operated, it is determined that the outdoor unit is not a faulty machine and the indoor unit may be a faulty machine; and if the outdoor unit cannot normally operate, determining that the outdoor unit is a fault machine. Similarly, when the air conditioner detector simulates to be connected with an indoor unit of an air conditioner to be detected and simulates an outdoor unit, if the indoor unit can normally operate, the indoor unit is determined not to be a fault machine, and the outdoor unit is determined to be a fault machine possibly; and if the indoor unit cannot normally operate, determining that the indoor unit does not have a fault. If both the outdoor unit and the indoor unit can operate normally, the communication line may fail.
For the central air conditioner, when the air conditioner detector is connected with an outdoor unit or an indoor extension of the air conditioner to be detected, after the analog centralized controller sends a third analog signal to the outdoor unit or the indoor extension, if the outdoor unit does not normally operate after the third analog signal is sent to the outdoor unit, the outdoor unit is determined to be possibly a fault machine; and if one or more indoor extension sets which do not normally operate exist after the third analog signals are respectively sent to the indoor extension sets, determining that the indoor extension sets which do not normally operate are possible to be fault machines. If both the outdoor unit and the indoor extension unit can operate normally, the communication line or the centralized controller may be in failure.
And when the fault machine is determined, acquiring the operating parameters of the fault machine through a data interaction interface. It can be understood that if it is difficult for field maintenance personnel to find out an accurate fault type according to a test operation result, further obtaining operation parameters of the fault machine is needed to analyze the operation parameters to determine the fault type.
Furthermore, the outdoor unit is connected with a display unit on the indoor main board through a physical connection unit so as to display the current operation parameters of the outdoor unit on the display. Therefore, the air conditioner detector can directly see the operation parameters when simulating the indoor unit, so that field maintenance personnel are not required to directly see the relevant operation parameters from the outdoor unit. And the outdoor unit is generally hung outdoors, so that the safety risk of field maintenance personnel is greatly reduced.
Further, the operation parameters are displayed in a display, and a comparison result of an actual value in each operation parameter and a corresponding set value range is output to determine abnormal operation parameters; and determining fault prompt information corresponding to the abnormal operation parameters, and displaying the fault prompt information through the display. In this embodiment, the air conditioner detector is configured with fault analysis software, and the software may compare an actual value of the operation parameter with a preset theoretical value range, so as to obtain an abnormal operation parameter of which the actual value is not within the preset theoretical value range. And after one or more abnormal operation parameters are determined, one or more fault type prompts are output, so that field maintenance personnel can perform preliminary investigation according to the abnormal parameters and the fault type prompts. If the actual fault type of the air conditioner to be detected is one of one or more fault type prompts, the field maintenance personnel can directly carry out corresponding repair.
Step S103: and transmitting the operation parameters to a pre-connected intelligent terminal, and uploading the operation parameters to a data background through the intelligent terminal so that the data background can determine the fault type based on the operation parameters.
Generally, on-site maintenance personnel can find the correct fault type according to own experience or fault type prompt on a display of an air conditioner detector and correspondingly maintain the fault type. However, since different field maintenance personnel have experience difference and the fault types of some air conditioners are complicated, the field maintenance personnel often have difficulty in determining the fault types.
In this embodiment, the air conditioner detector is connected to the intelligent terminal in advance based on the wireless connection unit, so that the operating parameters are uploaded to the data background through the intelligent terminal, and the data background determines the fault type based on the operating parameters. After the remote technician obtains the operation parameters from the data background, the fault type can be quickly determined, and the fault type is fed back to field maintenance personnel through the intelligent terminal. In addition, the data background can be also provided with an intelligent fault type analysis system, the intelligent fault type analysis system is obtained according to a large amount of training operation data in a training mode, and the corresponding fault type can be output according to input operation data, so that automatic analysis of the fault type can be achieved based on the intelligent fault type analysis system. Therefore, the remote diagnosis of the air conditioner fault is realized, and the maintenance efficiency is greatly improved.
The remote diagnosis of the air conditioner fault is realized through the intelligent terminal and the data background. Specifically, referring to fig. 4, fig. 4 is a schematic view of a first embodiment of the fault detection method of the air conditioner of the present invention. As shown in fig. 4, after the air conditioner detector is connected with the air conditioner to be detected, the air conditioner detector is connected with the intelligent terminal through the wireless connection unit, and the intelligent terminal uploads the operation parameters of the fault machine to the data background so that a remote technician or an intelligent fault type analysis system can determine the fault type, thereby realizing remote diagnosis of the air conditioner. It can be understood that the air conditioner detector can also be directly in wireless connection with the data background to directly transmit the operation parameters to the data background. For example, the air conditioner detector with the WIFI module may directly upload the operation parameters to the data background after being connected to the WIFI signal.
Further, after the air conditioner detector uploads a large number of operation parameters, the data background can analyze and count the large number of operation parameters, optimize the set operation parameters of each operation mode, obtain new set operation parameters which meet the user requirements better and are more energy-saving and environment-friendly, and obtain a new control program.
According to the scheme, after the air conditioner to be detected is connected with the air conditioner to be detected through the physical connection unit, an analog signal is sent to the air conditioner to be detected, so that the air conditioner to be detected can run in a test mode; determining a fault machine according to a test operation result, and acquiring operation parameters of the fault machine; and transmitting the operation parameters to a pre-connected intelligent terminal, and uploading the operation parameters to a data background through the intelligent terminal so that the data background can determine the fault type based on the operation parameters. Therefore, after the air conditioner detector is connected with the air conditioner to be detected, the fault machine is determined and the operation parameters are obtained through trial operation, so that the operation parameters are uploaded to the data background by the intelligent terminal, remote diagnosis is realized, and the maintenance efficiency is improved.
As shown in fig. 5, a second embodiment of the present invention proposes a method for detecting a fault of an air conditioner, which is based on the first embodiment shown in fig. 3, and further includes:
step S201: receiving a new control program sent by a data background and storing the new control program in a memory;
and after the air conditioner detector is connected with the data background, receiving a new control program sent by the data background. Or the air conditioner detector is connected with the intelligent terminal, and the intelligent terminal downloads the new control program of the data background to the air conditioner detector so that the air conditioner detector can store the new control program in the memory.
Step S202: and after the control unit is connected with a control unit of an indoor main board in the air conditioner to be detected through a signal wire, the new control program is transmitted to the control unit so as to control the operation of the air conditioner to be detected based on the new control program.
Generally, an indoor main board of an air conditioner includes a control unit in which a control program is stored and an operation of the air conditioner is controlled based on the control program. When the air conditioner detector is connected with a control unit of an indoor main board in the air conditioner to be detected through a signal wire, and a new control program stored in a memory is transmitted to the control unit, the air conditioner obtains the new control program.
Specifically, the transmitting the new control program to the control unit includes:
if the update type of the control program is confirmed to be incremental update, the new control program is obtained and compared with the element control program in the control unit to obtain a difference directory, a new file and a changed file are determined based on the difference directory, and the new file and the changed file are transmitted to the control unit;
therefore, only the newly added files and the changed files are transmitted, the transmission time can be saved, and the transmission flow can be saved. For example, if the new control program is compared with the original control program and timing control is added, the file related to the timing control is an added file; if the rotating speed of the indoor fan in the original refrigeration mode is changed from V1 to V2, the file related to the rotating speed of the indoor fan in the refrigeration mode is a changed file. When the control unit of the indoor main board of the air conditioner receives the newly added file, directly storing the newly added file; and if the received modified file is the modified file, replacing the original file with the modified file to obtain a new control program.
And if the update type of the control program is confirmed to be global update, completely transmitting the new control program to the control unit. The global update is a data packet of a control program originally stored by a control unit of an indoor main board of a formatting air conditioner, and a complete data packet of a new control program is stored and obtained. Therefore, the integrity of a new control program can be ensured, and the debugging pressure is reduced.
According to the scheme, the new control program sent by the data background is received and stored in the memory; and after being connected with a control unit of an indoor main board in the air conditioner to be detected through a signal wire, the new control program is transmitted to the control unit so as to control the operation of the air conditioner to be detected based on the new control program. Therefore, the control program of the air conditioner is updated, and after-sale maintenance of the air conditioner is facilitated.
In addition, the embodiment also provides a fault detection device of the air conditioner. Referring to fig. 6, fig. 6 is a functional block diagram of a fault detection device of an air conditioner according to a first embodiment of the present invention.
