Embodiment Construction

[0035] The principles and embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] Such as figure 1 As shown, in the group system of the air conditioner of the present invention, one of the units can be set as the group control terminal (master), and the rest are slaves. They are connected through the CAN bus network, and each unit has a group attribute. The group attribute can be set as: join group control or not join group control. If you join the group control, it will be uniformly scheduled by the host. If you don’t join the group control, it will not be scheduled by the group control terminal (host), and it will run independently. The host acquires and analyzes the data of the operating status of all units at regular intervals, performs unified scheduling and control of the units in the group, and broadcasts important status data of the group, such as the operating status of each unit in the group, so ...

Abstract

The invention discloses an air conditioning grouping system capable of improving reliability and a grouping control method. The grouping control method of an air conditioning comprises the steps thatthe operation status of units in a group is obtained by the group control end at intervals and is processed to obtain operation modes of the group; dispatching units and a dispatching order thereof are determined by the group control end according to dispatching attributes and the operation status of the units, and an issuing order is formulated according to a certain temperature order or a humidity order and the different operation modes in the dispatching order; and the group control end issues mode commands to the dispatching units for executing according to the issuing order. According tothe air conditioning grouping system capable of improving the reliability and the grouping control method, the competitive operation between slaves can be avoided, the temperature changes can furtherbe quickly responded, and the safety and the reliability of group operation are improved.

Description

technical field [0001] The invention relates to a computer room air conditioner group system and a group control method. Background technique [0002] Existing computer room air conditioners are widely used in data centers, rail transit and other fields. The existing technology can make a single air conditioner run safely and reliably, and perform direct maintenance on site. With the rapid development of information technology, many computer rooms have realized PC-side remote monitoring, including data such as temperature, humidity, and faults, and can perform remote control, such as: power on and off, temperature and humidity settings. However, due to the particularity of its use occasions, computer room air conditioners have high requirements for safety and reliability, and group control is required. A group is generally a cold aisle or a hot aisle. However, the existing group control method is unreasonable, the operation reliability is low, and it is impossible to ensure...
