And 102, generating prompt information for indicating the relation between the vibration damping device and the refrigerant pipeline based on the position relation.
In the embodiment of the application, the position relation between the vibration damping device and the refrigerant pipeline is determined according to whether the position relation between the detection device and the vibration damping device changes or not, and prompt information is generated to prompt a user that the vibration damping device falls off from the refrigerant pipeline.

Wherein, the working state of the proximity switch is controlled by the distance between the proximity switch and the inductive object.
In the embodiment of the application, the proximity switch is a position switch which can be operated without mechanical direct contact with a moving part, and when the sensing surface of the proximity switch senses the action distance of a sensing object, the proximity switch can be actuated without mechanical contact and any pressure, so that a direct current electric appliance is driven or a control instruction is provided for a computer device.

The proximity switches are of the inductive, capacitive, hall, ac and dc type. The detection equipment comprises a proximity switch or an induction object and is arranged on at least one pipeline in the refrigerant pipeline, the detection equipment comprises another module and is correspondingly arranged on the corresponding vibration damping device, and therefore when the vibration damping device moves, the on-off state of the proximity switch can be changed, and whether the vibration damping device falls off or not can be determined through the on-off state of the proximity switch.

In the embodiment of the application, whether the working state of the proximity switch is switched or not is detected, and the position relation between the vibration damping device and the detection equipment is determined according to whether the working state of the proximity switch is switched or not. In some application scenarios, the vibration damping device may be a foamed material made of a damping material.

And step 204, displaying prompt information.
Based on the foregoing embodiments, in other embodiments of the present application, step 202 may be implemented by step 202a or step 202 b; wherein, if the working state of the proximity switch is detected to be the initial first state, step 202 is implemented by step 202 a; if it is detected that the operating state of the proximity switch is switched from the first state to the second state, step 202 is implemented by step 202 b:
step 202a, if the working state of the proximity switch is detected to be the initial first state, determining that the position relation is unchanged.
The unchanged position is used for indicating that the position between the vibration damper and the refrigerant pipeline is not changed.
In this embodiment of the application, when the operating state of the proximity switch is the initial first state, that is, the operating state of the proximity switch is always maintained as the first state, it is determined that the position between the vibration damping device and the refrigerant pipeline is not changed, that is, it is determined that the vibration damping device does not fall off from the refrigerant pipeline. The first state may be a proximity switch open state or a connected state.
Step 202b, if the working state of the proximity switch is detected to be switched from the first state to the second state, determining that the position relation is position change.
The position change is used for indicating that the position between the vibration damper and the refrigerant pipeline is changed.
In the embodiment of the present application, when a first state of the proximity state is a disconnection state, a second state is a connection state; when the first state is a connection state, the second state is a disconnection state.
Based on the foregoing embodiments, the detection device is taken as an example of a hall proximity switch, where a schematic diagram of the hall proximity switch installed in an outdoor unit can be shown in fig. 3. In fig. 3, the refrigerant pipe 31 of the outdoor unit, the vibration damping device 32, the compressor 33, the hall switch 34, and the outdoor unit chassis 35 are included, wherein the hall proximity switch 34 includes a hall switch assembly 341 and a magnetic assembly 342. In some application scenarios, the refrigerant pipeline of the outdoor unit may be a four-way valve pipeline component, and the vibration damping device may be a novel damping foam material, for example, a polyurethane damping foam material.
The four-way valve pipeline part is wrapped by polyurethane damping foaming materials, the Hall switch assembly 341 is installed on one pipeline of the refrigerant pipeline, and the magnetic assembly 342 is installed on the polyurethane damping foaming materials corresponding to the pipeline where the Hall switch assembly 341 is located.
When the distance between the magnetic assembly and the Hall switch assembly is changed, the magnetic assembly causes the magnetic field sensed by the Hall switch to change, so that the circuit state in the Hall switch is changed due to the Hall effect of the Hall element, and the Hall switch is controlled to be in a conducting state or a disconnecting state. Therefore, the dropping condition of the polyurethane damping foaming material of the refrigerant pipeline can be monitored through the Hall proximity switch.
Wherein, the mountable position of placing of hall switch subassembly or magnetic component has: the return pipe, the exhaust pipe, the low-pressure valve connecting pipe and/or the condenser connecting pipe in the refrigerant pipeline.
Correspondingly, when the hall proximity switches are installed in the outdoor unit at the positions shown in fig. 3, that is, when the hall proximity switches are disposed on the side of the vibration damping device 32 close to the end face of the outdoor unit chassis 35, the switch states of the corresponding hall switches default to the off states, and a corresponding fault detection method can be implemented by the following steps:
the method comprises the following steps: and the air conditioning equipment is started to operate, and simultaneously, the synchronous starting is carried out to monitor the on-off state of the Hall switch.
Step two: and judging whether the switching state of the Hall switch is switched from the off state to the on state.
Wherein, when setting up magnetic component and hall switch assembly, distance between magnetic component and the hall switch should be greater than the preset distance that makes hall switch on, this moment, hall switch's on-off state is the off-state, and like this, when polyurethane damping expanded material drops downwards, distance between magnetic component and the hall switch diminishes, makes distance between magnetic component and the hall switch be less than or equal to preset distance, and at this moment, hall switch's on-off state takes place to switch over, switches over for the on-state, and what correspond can be in order to confirm that polyurethane damping expanded material drops.
For example, as shown in fig. 4, a distance relationship state between the magnetic assembly 341 and the hall switch 342 is shown, where the distance between the magnetic assembly and the hall switch is L, a distance threshold value at which the hall switch is turned on is S, and when L < S, it indicates that the polyurethane damping foam material falls downward, and there is a fall failure; otherwise, the polyurethane damping foaming material does not fall off downwards.
And step three, when the on-off state of the Hall switch is determined to be the off state, a prompt message that the polyurethane damping foam material does not fall off downwards is generated and displayed.
And step four, when the switching state of the Hall switch is determined to be switched from the off state to the on state, a prompt message that the polyurethane damping foam material falls off downwards is generated and displayed.
In the fourth step, the prompt message may include an alarm message such as a sound or a warning message such as a red warning message, so that the user can find that the polyurethane damping foam material falls off as soon as possible.
The embodiment of the present application further provides a fault detection method, where when the hall proximity switches are disposed on the farthest end face side of the vibration damping device 32 opposite to the outdoor unit chassis 35, the switching states of the corresponding hall switches are defaulted to the on state, and the method may be implemented by the following steps:
the method comprises the following steps: and the air conditioning equipment is started to operate, and simultaneously, the synchronous starting is carried out to monitor the on-off state of the Hall switch.
Step two: and judging whether the switching state of the Hall switch is switched from the on state to the off state.
Wherein, when setting up magnetic component and hall switch assembly, distance between magnetic component and the hall switch should be less than or equal to the predetermined distance that makes hall switch on, this moment, hall switch's on-off state is the conducting state, and like this, when polyurethane damping expanded material drops downwards, distance grow between magnetic component and the hall switch, make distance between magnetic component and the hall switch be greater than predetermined distance, and at this moment, hall switch's on-off state takes place to switch over, switches over to the off-state, and what correspond can be in order to confirm that polyurethane damping expanded material drops.
Step three: and when the switching state of the Hall switch is determined to be a conducting state, a prompt message that the polyurethane damping foam material does not fall off downwards is generated and displayed.
Step four: and when the switching state of the Hall switch is determined to be switched from the on state to the off state, generating and displaying prompt information that the polyurethane damping foaming material falls off downwards.
In the fourth step, the prompt message may include an alarm message such as a sound or a warning message such as a red warning message, so that the user can find that the polyurethane damping foam material falls off as soon as possible.
