Embodiment 1

[0064] Such as Figure 4 As shown, this embodiment provides a fault detection method for controlling the heat pump heating equipment 100 according to any embodiment of the present invention. The fault detection method includes:

[0065] Step S102, the fault detection device outputs a closing signal to the relay of the compressor;

[0066] Step S104, the collecting device collects the operating parameters of the heat pump heating equipment;

[0067] Step S106, the fault detection device detects the fault of the relay according to the operating parameters.

[0068] The fault detection method in this embodiment is specifically: after the fault detection device 200 outputs a shutdown signal to the compressor 140, the acquisition device 160 starts to collect the operating parameters of the heat pump heating equipment 100, and the fault detection device 200 detects whether the relay 150 exists according to the operating parameters Fault. Wherein, when the detection result of the ...

Embodiment 2

[0072] Such as Figure 5 with Image 6 As shown, this embodiment provides a fault detection method. In addition to the technical features of the foregoing embodiments, this embodiment further includes the following technical features.

[0073] The operating parameters include the water temperature of the water storage device, and the fault detection device detects the fault of the relay according to the operating parameters, specifically including:

[0074] Step S202, based on the fact that the water temperature is greater than or equal to the first target water temperature and the temperature difference between the water temperature and the first target water temperature is greater than or equal to the first temperature difference threshold, the fault detection device determines that there is a fault in the relay; or

[0075] Step S302, based on the fact that the water temperature is less than the first target water temperature, or based on the fact that the water temperatur...

Embodiment 3

[0084] Such as Figure 7 with Figure 8 As shown, this embodiment provides a fault detection method. In addition to the technical features of any of the above embodiments, this embodiment further includes the following technical features.

[0085] The operating parameters include the current of the compressor, and the fault detection device detects the fault of the relay according to the operating parameters, specifically including:

[0086]Step S402, based on the fact that the current is greater than or equal to the current threshold, the fault detection device determines that there is a fault in the relay; or

[0087] Step S502, based on the fact that the current is less than the current threshold, the fault detection device determines that the relay is normal.

[0088] In this embodiment, the current of the compressor 140 can be detected and collected by the current collection device 164 . The current collection device 164 can specifically be a current sampling resistor ...

Abstract

The invention provides a fault detection method, heat pump heating equipment, a fault detection device and a storage medium. The heat pump heating equipment includes a compressor, a relay, a collection device and the fault detection device. The relay is used to control the turn-on and turn-off of the compressor; the collection device is used to collect the operation parameters of the heat pump heating equipment; and the fault detection device outputs a turn-off signal to the relay, and detects the fault of the relay according to the operation parameters. The technical scheme can prolong the service life of the compressor and guarantee the safety of a user.

Description

technical field [0001] The invention relates to the technical field of heat pump heating equipment, in particular to a fault detection method, heat pump heating equipment, a fault detection device and a storage medium. Background technique [0002] In the related art, the start and stop of the compressor are controlled by the on and off of the relay. However, when the relay fails and the compressor cannot be stopped normally, it will cause the compressor to continue to work. For heat pump heating equipment, the failure of the compressor relay will bring safety hazards to users. Contents of the invention [0003] The present invention aims to solve at least one of the above technical problems. [0004] Therefore, the first object of the present invention is to provide a fault detection method. [0005] The second object of the present invention is to provide a heat pump heating device. [0006] The third object of the present invention is to provide a fault detection de...
