In one embodiment, the air conditioning system is a multi-split heat recovery system, and is composed of N stages according to a communication bus. The process of automatic addressing is also divided into N steps.
Here, the topology of the air conditioning system shown in fig. 11 is taken as an example to describe the scheme, the air conditioning system is divided into three stages, the first stage is a communication master node, i.e., an outdoor unit, the second stage is an intermediate node, i.e., an MS (refrigerant switching device), and the third stage is a slave node, i.e., an indoor unit, a water conservancy module, a total heat exchanger, a fresh air fan, and the like of an air conditioner.
After detecting that the main node (outdoor unit) is electrified, inquiring all the on-line intermediate nodes (MS) and the on-line slave nodes (indoor unit, water conservancy module, total heat exchanger, fresh air fan and the like), classifying the collected on-line nodes, storing corresponding address information according to the classification of the intermediate nodes and the slave nodes, and generating two sequences.
And the sequence A stores the address information of the intermediate nodes according to a certain sequence.
And the sequence B stores slave node address information according to a certain sequence.
Where the invalid address is represented by 0xFF, for a machine that has not been auto-addressed, the contents of sequence a and sequence B are as follows:
sequence A: 0xFF, 0xFF, 0xFF, … …, 0xFF
Sequence B: 0xFF, 0xFF, 0xFF, … …, 0xFF
After entering automatic addressing, in a first step, configuring addresses of an intermediate node and a slave node mounted on a master node, specifically as follows:
two address databases are prestored and are respectively used for distributing addresses to the intermediate node and the slave node.
For the intermediate node (MS), address sequence numbers are assigned in order from small to large starting from 0. During the allocation process, the existing address sequence number (the existing sequence number in sequence a) needs to be skipped.
At this time, the contents of sequence a and sequence B are as follows:
sequence A: 0, 1, 0xFF, … …, 0xFF
Sequence B: 0xFF, 0xFF, 0xFF, … …, 0xFF
For the slave nodes, address sequence numbers are assigned in order from small to large starting from 0. In the process of allocation, the existing address sequence number (the existing sequence number in the sequence B) needs to be skipped.
At this time, the contents of sequence a and sequence B are as follows:
sequence A: 0, 1, 0xFF, … …, 0xFF
Sequence B: 0, 1, 0xFF, … …, 0xFF
And secondly, configuring addresses for the slave nodes mounted on the intermediate nodes.
For the slave nodes, address sequence numbers are assigned in order from small to large starting from 0. In the process of allocation, the existing address sequence number (the existing sequence number in the sequence B) needs to be skipped.
At this time, the contents of sequence a and sequence B are as follows:
sequence A: 0,1
Sequence B: 0,1,2,3,4,5,6,7,8
After the above steps are completed, all the intermediate nodes and the slave nodes are allocated unique addresses.
By the method, the address configuration is carried out on the air conditioning system of the complex multi-stage multi-online heat recovery system, and the automatic addressing and distribution of the intermediate nodes and the slave nodes in the communication network are realized. The method for realizing the hierarchical automatic addressing is suitable for complex and multistage multi-online systems. Even if the communication is increased in stages, automatic addressing can be realized according to the idea of the invention, so that the manual operation is greatly simplified, the problem that manual setting is easy to make mistakes is avoided, and great convenience is brought to engineering installation and user use.
