Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings.

Fig. 1 is a flowchart illustrating an air conditioner fault detection method according to an exemplary embodiment. As shown in fig. 1, the method includes the following steps.
In step S101, when the air conditioner is in the heating mode and the electric heating module of the indoor unit is in the operating state, in response to receiving an auxiliary heating function closing instruction for instructing the electric heating module to close, a voltage at an output terminal of the auxiliary heating relay, a current at the output terminal of the auxiliary heating relay, and a temperature of the electric heating module are acquired.
When the heating demand of a user is high (for example, in winter), the electric heating module can be controlled to be turned on to realize rapid heating under the condition that the air conditioner is in the heating mode. The electric heating module can be controlled to be turned on or off through the auxiliary thermal relay. In a plurality of scenarios, the user can send an auxiliary heating function closing instruction for instructing the electric heating module to close through a mobile terminal (such as a mobile phone) or a remote controller. For example, when the user controls to turn off the electric heating module, the control sends an auxiliary heating function turning-off instruction for instructing the electric heating module to turn off; when a user controls to close the air conditioner, controlling to send an auxiliary heating function closing instruction for indicating the electric heating module to be closed; when a user adjusts the working mode of the air conditioner from a heating mode to a cooling mode, the auxiliary heating function closing instruction used for indicating the electric heating module to be closed is controlled and sent. After the air conditioner side receives an auxiliary heating function closing instruction for indicating the electric heating module to be closed, the auxiliary heating relay can be controlled to be disconnected, and meanwhile, the voltage of the output end of the auxiliary heating relay, the current of the output end of the auxiliary heating relay and the temperature of the electric heating module are obtained. If the auxiliary thermal relay has adhesion fault, the risk of fire hazard exists.
In step S102, it is determined whether the secondary thermal relay has a sticking fault according to the acquired voltage, current, and temperature.
The voltage at the output end of the auxiliary thermal relay, the current at the output end of the auxiliary thermal relay and the temperature of the electric heating module are different before and after the auxiliary thermal relay is in adhesion fault, for example, if the auxiliary thermal relay is not in fault, the electric heating module stops running, the temperature stops rising, after the auxiliary thermal relay is in adhesion fault, the electric heating module is still in a working state, and the temperature of the electric heating module continuously rises. After the voltage at the output end of the auxiliary thermal relay, the current at the output end of the auxiliary thermal relay and the temperature of the electric heating module are obtained, whether the auxiliary thermal relay has the adhesion fault or not can be determined according to the obtained voltage, current and temperature

When the acquired voltage is less than the predetermined voltage threshold, the acquired current is less than the predetermined current threshold and the acquired temperature is less than the predetermined first temperature threshold, it may be determined that the electric heating circuit in which the electric heating module is located is open, the electric heating module stops operating, and thus it may be determined that the auxiliary thermal relay has not generated the adhesion fault. The current threshold may be preset by the designer, and may be, for example, 0.5A. The first temperature threshold may be preset by the designer, and may be, for example, 75 ℃.

The fault type is that the auxiliary thermal relay has adhesion fault.

In another embodiment, the method further comprises:
if the auxiliary thermal relay is determined to have the adhesion fault, sending a first alarm instruction to the user terminal, wherein the first alarm instruction is used for indicating the user terminal to output an alarm message; or if the auxiliary thermal relay is determined to have the adhesion fault, sending a second alarm instruction to the server, wherein the second alarm instruction is used for indicating the server to send a third alarm instruction to the user terminal associated with the air conditioner, and the third alarm instruction is used for indicating the user terminal to output an alarm message.
The first alarm instruction is used for indicating a user terminal to output an alarm message, after the auxiliary thermal relay is determined to have adhesion fault, the first alarm instruction can be sent to the user terminal (such as a mobile phone), and the user terminal can output a popup message on a screen after receiving the first alarm instruction: the auxiliary thermal relay is required to cut off the power supply of the air conditioner in time when the auxiliary thermal relay is in adhesion fault. The air conditioner and the user terminal can communicate in modes of Bluetooth, WIFI, 3G, 4G, 5G and the like.
And after the auxiliary thermal relay is determined to have the adhesion fault, sending a second alarm instruction to the server, wherein the second alarm instruction is used for instructing the server to send a third alarm instruction for instructing the user terminal to output an alarm message to the user terminal (such as a mobile phone) associated with the air conditioner. The user terminal can output a popup message on the screen after receiving the third alarm instruction: the auxiliary thermal relay is required to cut off the power supply of the air conditioner in time when the auxiliary thermal relay is in adhesion fault.

The first alarm instruction can also be preferentially sent to the user terminal, when the user terminal receives the first alarm instruction sent by the air conditioner, a response message can be fed back to the air conditioner, if the communication between the air conditioner and the user terminal fails, the air conditioner does not receive the response message fed back by the user terminal within a preset time, and a second alarm instruction used for indicating the server to send a third alarm instruction to the user terminal associated with the air conditioner can be sent to the server.
In this embodiment, through the two mutually redundant methods for instructing the ue to output the alarm message, when one of the methods cannot enable the ue to output the alarm message, the other method of redundancy can reliably and effectively instruct the ue to output the alarm message.
When the adhesion fault of the auxiliary thermal relay is determined, a first alarm instruction can be sent to the user terminal while the air conditioner end outputs a fault prompt message, a second alarm instruction can be sent to the server while the air conditioner end outputs the fault prompt message, and the first alarm instruction can be sent to the user terminal and the second alarm instruction can be sent to the server while the air conditioner end outputs the fault prompt message.

The predetermined time period may be preset by a designer, and may be 3min, for example. When the timing time from the determination of the adhesion fault of the auxiliary thermal relay reaches a preset time, the air conditioner is in a power-on state, and the obtained temperature of the electric heating module is not less than a preset second temperature threshold value, the duration of the adhesion fault of the auxiliary thermal relay is considered to be longer, the air conditioner is in the power-on state (the power supply of the air conditioner is not cut off by a user), the electric heating module is continuously in an operating state, the temperature of the electric heating module is higher, and a fire risk exists. The second temperature threshold may be preset by the designer, and may be, for example, 100 ℃.
