Embodiment Construction

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, specific embodiments will be described in detail below with reference to the accompanying drawings.

[0031] The present invention aims at the false alarm of the air conditioner monitoring board caused by power failure in the prior art, which increases the number of unnecessary alarms, and because the maintenance personnel cannot distinguish the specific cause of the alarm, they need to go to the base station for air conditioner maintenance, resulting in To avoid the rise of labor costs, a method for alarm detection of air-conditioning power supply status is provided, such as figure 2 As shown, the method is used for an air-conditioning monitoring board, including:

[0032] Step 201, determine whether there is electrical signal transmission on the main control board of the air conditioner according to a preset detection strategy;

[0033] Step 202, ...

Abstract

The invention discloses an air conditioner power supply state alarm detection method and device. The method is used for an air conditioner monitor plate and comprises determining whether an electric signal is transmitted in an air conditioner main control board according to a preset detection strategy; when determining that the electric signal is transmitted in the air conditioner main control board, determining whether the air conditioner monitor plate can realize signaling information interaction with the air conditioner main control board; and when determining that the air conditioner monitor plate cannot realize signaling information interaction with the air conditioner main control board, determining that fault is caused between the air conditioner monitor plate and the air conditioner main control board, and reporting the fault through an alarm message. Through the scheme above, the problem that in the prior art, since power failure of an air conditioner is often erroneously assumed to be caused by communication failure between the air conditioner monitor plate and the air conditioner main control board, and wrong fault warning is given, the maintenance cost is improved is solved, thereby reducing unnecessary alarming times, improving air conditioner maintenance efficiency and reducing base station maintenance cost.

Description

technical field [0001] The invention relates to the technical field of air conditioner monitoring, in particular to an air conditioner power state alarm detection method and device. Background technique [0002] In the prior art, when detecting a fault between the air conditioner monitoring board and the main control board of the air conditioner, the air conditioner monitoring board usually determines it according to the signaling message of the main control board of the air conditioner acquired in real time. The structural diagram of the fault detection method is specific Such as figure 1 shown. [0003] Specifically, the air conditioner monitoring board takes power from the switching power supply through the power line (dotted line), which uses a fuse with a maximum current of 10A, and is connected to the main control board of the base station air conditioner through the signaling line (solid line). The air conditioner has an independent power supply device; the air cond...
