Embodiment Construction

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] Please also refer to Figure 1 to Figure 3 , the start-up prevention detection method provided by the embodiment of the present invention will now be described. The start-up prevention detection method includes the following steps: before the load starts to run, the detection threshold is set in advance, and a test voltage is applied to the load, and the value range of the test voltage is 0-36V. The detection parameters of the load are integrated, and the detection parameters are compared with the detection threshold. If the detection parameters fall within...

Abstract

The invention provides a start-up prevention detection method, system and air conditioner. The start-up prevention detection method includes setting a detection threshold before the load starts to run, and applying a test voltage to the load; integrating the detection parameters of the load, and combining the detection parameters with the detection threshold In comparison, if the detection parameter falls within the range of the detection threshold, the load starts, otherwise, the load remains in a shutdown state. Compared with the prior art, the start-up prevention detection method provided by the present invention adds a test voltage to the load, detects the detection parameters of the load, and compares them with the detection threshold, and only allows The load starts. Before the load is running, the trial operation is carried out to check whether the load is operable, which avoids the situation that the direct start of the load is likely to cause the load to fail, and greatly improves the safety of the load startup.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and more specifically relates to a start-up prevention detection method, system and air conditioner. Background technique [0002] With the improvement and improvement of people's lives, various electrical appliances have become an indispensable part of people's lives. [0003] Some methods of using electrical appliances have always been very important and necessary for people to use electrical appliances. These usage methods are closely related to the control methods of electrical appliances. When there is a problem with the control method, it will greatly affect the use of electrical appliances. [0004] Take the air conditioner as an example, when the air conditioner has an abnormality, such as a damaged load line, short circuit of the device, damage to the enameled wire, etc., the control system cannot identify it in time, and will try to start it many times without knowing whether i...
