Embodiment 1

[0040] Embodiment 1, a method for allocating addresses of indoor units of a central air-conditioning system. Before explaining the method provided in Embodiment 1, it should be understood that in the design of the central air-conditioning system, the outdoor unit can be used as the master, and the indoor unit can be used as the slave. Usually, one master receives control commands from multiple slaves. The master analyzes and synthesizes the control commands of multiple slaves to meet the requirements of the control commands of multiple slaves. That is, the outdoor unit analyzes and synthesizes the control commands of multiple slaves, and adjusts the settings of the outdoor unit to meet the requirements of the control commands of multiple slaves. see figure 1 As shown, the steps of the method include:

[0041] Step A1, each indoor unit in the central air-conditioning system is initialized, and each indoor unit not assigned an address randomly generates an indoor unit test add...

Embodiment 2

[0055] Embodiment 2. A method for assigning addresses to indoor units of a central air-conditioning system. Among them, in the first embodiment, it is to realize a general method provided by the embodiment of the present invention; in order to better understand the embodiment of the present invention, in the second embodiment, the indoor unit and the outdoor unit of the central air-conditioning system are used Describe the operations performed on each side. see figure 2 and image 3 As shown in FIG. 1 , before assigning addresses to the indoor units of the central air-conditioning system, the central air-conditioning system must first be powered on, that is, the indoor unit and the outdoor unit shall be powered on. A method for assigning addresses to indoor units of a central air-conditioning system provided in Embodiment 2 includes:

[0056] Step B1, the outdoor unit generates polling information including address information, the polling information is broadcast informat...

Embodiment 3

[0095] Embodiment three, a kind of indoor unit of central air-conditioning system, refer to Figure 5 , including: an address generating unit 10 , a receiving unit 20 , a judging unit 30 , a sending unit 40 and an address assigning unit 50 .

[0096] Wherein, the address generating unit 10 is used to randomly generate an address during initialization;

[0097] The receiving unit 20 is configured to receive polling information and address setting commands sent by the outdoor unit, where the polling information includes address information;

[0098] The judging unit 30 is configured to judge whether the address information contained in the received polling information matches the address information randomly generated in the address generating unit 10;

[0099] A sending unit 40, configured to send a polling information response to the outdoor unit when the result in the judging unit 30 is yes, and send a setting success response to the outdoor unit;

[0100] The address assig...

Abstract

The embodiment of the invention discloses a method for assigning an address to an indoor unit of a central air-conditioning system, a device and a system thereof, wherein, the method for assigning the address to the indoor unit of the central air-conditioning system comprises the following steps: an outdoor unit sends a polling message to the indoor unit; wherein, the polling message comprises an outdoor testing address generated by the outdoor unit; the indoor unit judges whether the testing address in the received polling message is consistent with a self assigned testing address, and sends a polling message response in the case of consistency; the outdoor unit judges whether the number of the received polling message response is one, and if so, the outdoor unit assigns the address and sends address setting commands to the indoor unit sending the polling message response, wherein, the address setting command sent each time comprises a unique communication address; and the indoor unit sets the self address according to the address setting commands. The adoption of the embodiment of the invention can correctly and quickly realize automatic assignment of the indoor unit address and avoid a fault caused by address assignment which is performed by a person.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a method, device and system for allocating addresses of indoor units of a central air conditioning system. Background technique [0002] With the continuous improvement of people's requirements for working and living environments, central air conditioning has become one of the necessary equipment in working and living. Especially in large-scale factories and commercial buildings, central air-conditioning is more because of its own advantages, such as: high cooling efficiency and energy utilization rate, low cooling cost per unit area, relatively uniform temperature distribution in the air-conditioning environment, low noise, and indoor air conditioning. The advantages of no condensate dripping and other advantages play a huge role in people's work and life. [0003] A central air conditioner usually consists of multiple indoor units and outdoor units. The indoor unit an...
