Embodiment 1

[0027] According to an embodiment of the present invention, an embodiment of a method for detecting the working state of a compressor is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0028] figure 1 is a flow chart of a method for detecting the working state of a compressor according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0029] Step S102, collecting temperature data corresponding to the current operating mode of the air conditioner.

[0030] Step S104, acquiring preset fault conditions corresponding to the current operating mode of the air conditioner.

[0031] In step S106, it is judged...

Embodiment 2

[0094] According to the embodiment of the present application, a device for detecting the working state of the compressor is also provided, such as Figure 4 As shown, the device may include: a collection module 42 , an acquisition module 44 and a judging module 46 .

[0095] Wherein, the collecting module 42 is used for collecting temperature data corresponding to the current operating mode of the air conditioner.

[0096] An acquisition module 44, configured to acquire preset fault conditions corresponding to the current operating mode of the air conditioner.

[0097] The judging module 46 is configured to judge whether the compressor of the air conditioner enters the reverse rotation state based on the preset fault condition and temperature data corresponding to the current operation mode.

[0098] According to the embodiment of the present invention, after the compressor of the air conditioner has been running for a period of time, it is judged whether the compressor of t...

Abstract

The invention discloses a method and a device for detecting a work state of a compressor. The method comprises the steps of collecting temperature data corresponding to a current operation mode of an air conditioner; acquiring a preset fault condition corresponding to the current operation mode of the air conditioner; based on the preset fault condition corresponding to the current operation mode of the air conditioner and the temperature data, judging that whether the compressor of the air conditioner enters an inversion state. Through the method and the device, the technical problem that whether the inversion of the compressor occurs or not cannot be judged in the prior art is solved, so that the compressor can be timely halted after the compressor enters the inversion state.

Description

technical field [0001] The invention relates to the field of air conditioner control, in particular to a method and device for detecting the working state of a compressor. Background technique [0002] With the development of the economy and the improvement of people's living standards, more and more household appliances have entered the families of ordinary people. The probability of the voltage of the grid being pulled down becomes higher and higher. The air conditioner is a large consumer of electricity. If the fixed-frequency scroll compressor of the air conditioner is started during the period when the voltage of the grid is pulled down, and it is running under heavy load, the compressor is very likely to reverse. [0003] The compressor is the core component of the air conditioner to achieve cooling / heating. When the scroll compressor is running in the reverse state, the cooling / heating effect of the air conditioner will be deteriorated. At the same time, the scroll c...
