Embodiment 1

[0042] Such as figure 1 As shown, a rotation method for a computer room air conditioner includes the following steps:

[0043] S101. The master air conditioner sequentially sends a control command to each slave air conditioner; the control command includes a receiving address and a standby address, and the receiving address is an address of one of the slave air conditioners.

[0044] S102. After the slave air conditioner receives the control command whose received address matches its own address, it responds according to the standby address in the control command, and generates a response command to feed back to the master air conditioner.

[0045] S103. The main air conditioner adjusts the standby address in the control instruction according to the response instruction.

[0046] The master air conditioner acts as the master to control the slave air conditioners (slave units), and sends control commands to each slave unit in sequence at regular intervals (for example, 500ms)....

Embodiment 2

[0064] A rotating duty system for a computer room air conditioner in this embodiment corresponds to the method in Embodiment 1, and reference is made to Embodiment 1 for details in this embodiment that are not yet detailed.

[0065] Such as image 3 As shown, a rotating duty system for computer room air conditioners includes a system applied to a master air conditioner and a system applied to a slave air conditioner. The system applied to a master air conditioner includes a sending module 101 and a first adjustment module 104. The slave air conditioner system includes a receiving module 102 and a responding module 103 .

[0066] The sending module 101 is configured to sequentially send a control command to each slave air conditioner; the control command includes a receiving address and a standby address, and the receiving address is an address of one of the slave air conditioners.

[0067] The receiving module 102 is configured to receive a control instruction whose receiving...

Abstract

The invention provides a rotating method and system of machine room air conditioners. The method comprises the following steps: transmitting, by a main air conditioner, a control instruction to each auxiliary air conditioner, wherein the control instruction comprises a receiving address and a standby address, and the receiving address is an address of one of the plurality of auxiliary air conditioners; after the auxiliary air conditioner receives the control instruction with the receiving address matched with the address, making response according to the standby address in the control instruction, generating a response instruction, and feeding back the response instruction to the main conditioner; and adjusting, by the main air conditioner, the standby address in the control instruction according to the response instruction. According to the rotating method and system of the machine room air conditioners, the operation of the auxiliary air conditioners is controlled by the main air conditioner, and the standby way can be adjusted in time according to the response instruction generated by the auxiliary air conditioner according to the response result of the control instruction, so that the rotating way of the air conditioner can meet different field requirements and is flexible and variable.

Description

technical field [0001] The present invention relates to the technical field of automatic control, and more specifically, relates to a method and system for rotating an air conditioner in a computer room. Background technique [0002] The main service object of the computer room air conditioner is the computer, which provides a stable and reliable IDC for the computer room and detects the working temperature, relative humidity, and air cleanliness of the computer room. It has the characteristics of high sensible heat ratio, high energy efficiency ratio, high reliability, and high precision. Reliability is the most important thing for a computer room. To run 8,760 hours a year without failure, reliable components and excellent control systems are required for the computer room air conditioner. Generally, the computer room has N+1 backup. If one air conditioner fails, the other air conditioners can immediately take over the entire system. [0003] In the prior art, the control...
