Method of monitoring multi-split air conditioner

Abstract

The invention relates to a method of monitoring a multi-split air conditioner, comprising the following steps: S1, connecting a PC (personal computer) communication interface to an outdoor unit circuit board that is provided with an RS232 interface module; S2, setting a monitor system at a PC, and configuring correspondingly the PC, the monitor system having four mode selection modules; S3, after configuring, selecting the corresponding module in step S2 as required to monitor the air conditioner. By designing the simple RS232 interface on an outdoor unit substrate, a data conversion module and other modules are omitted for the air conditioner with a monitor, data transmission timeliness is good, data transmission speed is high, and the cost is reduced; by acquiring data half an hour before a failure, great convenience is brought to engineering maintainers to analyze and judge the failure; displaying is done in forms of Excel graphics or lists, providing greater visualization and facilitating observation analysis for technicians.

Description

technical field [0001] The invention relates to an air conditioner monitoring, maintenance and management realization technology, in particular to a multi-connected air conditioner monitoring method. Background technique [0002] With the need for safe operation of equipment and energy conservation, as well as the continuous improvement of intelligent technology, the strengthening of intelligent control, maintenance management and remote centralized online monitoring of air conditioners and other high-energy-consuming equipment has attracted more and more attention from enterprises and other technical personnel. [0003] Especially for after-sales and engineering maintenance departments, it is of great significance to know the operating parameters of air conditioners in real time, and to make timely maintenance and debugging of abnormal machines. At present, when monitoring multi-connected air conditioners, during the data transmission process, due to the special protocol of...

Problems solved by technology

At present, when monitoring multi-connected air conditioners, during the data transmission process, due to the special protocol of the manufacturer (usually using the traditional 485 bus mode), when reading the operating parameters of the air conditioner, usually the external unit board of the air conditioner needs to be connected to other gateway devices ( Converter, etc. to convert the data) and then connect to the PC to collect monitoring data. This method has high bit error rate, low transmission rate, and poor real-time performance.

When monitoring multiple sets of units at the same time, the operating parameters of the air conditioner are not easy to monitor. Even if the fault data is detected, it is difficult to find the corresponding machine number, which is not convenient for fault analysis and judgment

[0004] Nowadays, there is no universal and simple interface to facilitate the reading of the operating parameters of the air conditioner, so as to facilitate its monitoring and maintenance; and there are defects such as poor intuition and incomplete data when reading the monitoring data; in order to improve the monitoring system , to improve data accuracy, the entire monitoring process needs to be further improved and perfected
