Address above mentioned distribution method is illustrated with reference to a specific embodiment, it should be noted, however, that should
Specific embodiment does not form the improper restriction to the application merely to the application is better described.
In this example, in order to solve the automatic assignment problem in CAN address of no master slave mode, realize that air-conditioner set is connected to
During air conditioner network, without the purpose of manual configuration mailing address, and reach and changing original air conditioner, the air conditioner after replacing
The purpose of the parameter of original air conditioner can be inherited, it is proposed that following address distribution method, to realize air conditioner CAN network
The automatic distribution address of unit, the plug and play of air-conditioner set is realized, without configuration.
Illustrated exemplified by using vav terminal VAV (air conditioning system with variable) as air-conditioner set, CAN address is automatic
Distribution may include steps of：
S1：Application IP addresses；
S2：Address is distributed；
S3：Time-out recovery
S4：Parameter reconstruction and Conflict solving.
Aforementioned four process is specifically described below as follows：
1) application IP addresses：
Trigger condition：VAV (Variable Air Volume Air Condition System, air conditioning system with variable)
Self address is detected as sky, or, VAV detects the control VAV time-out for itself receiving display board.
Application process：Poll application.
Terminate application condition：VAV applications stop application to IP address, in the case where VAV applies to IP address, open just
Often interactive transmission-receiving function.
2) address is distributed：
Trigger condition：Receive VAV application IP addresses frame.
Assigning process：It is related to data structure (that is, MAC mapping tables), the table can be illustrated in figure 3 8x4 bivariate table,
Wherein, including：Mac sections, can IP sections, (Modbus address fields, timestamp section.Based on the data structure, can by traversal,
Inquiry, increase, delete, renewal, sequence etc. operation, MAC mapping tables are operated, arrive first first, address i.e. sequence number.
Terminate distributive condition：Stop distribution after display board allocative efficiency IP address, or, display board allocative efficiency IP address
The transmission-receiving function that VAV corresponding to opening afterwards is normally interacted.
Basic assigning process 1：MAC Address section is inquired about, if record, then returns to address (sequence corresponding to the MAC Address section
Number).If do not recorded, Mac address fields are inquired about, corresponding IP of first Mac address field equal to 0 is returned into (sequence number).Note
Mac address fields, IP sections, Modbus sections (belonging to producer's level parameter, can set), timestamp (being used for time-out recovery address) are recorded,
Store table status.
Basic assigning process 2：MAC Address section is inquired about, if table according to above-mentioned basic assigning process 1 less than performing.Such as
Fruit table is full, then inquires about IP address section, and the corresponding IP (sequence number) that first IP address section is equal to 8 (invalid addresses) is returned.Note
Recording MAC address section, IP sections, Modbus sections (belonging to producer's level parameter, can set), timestamp (being used for time-out recovery address),
Store-memory table status.
3) time-out recovery：
Trigger condition：Effective IP address, overtime reclaim mechanism corresponding to unlatching is assigned in corresponding VAV.
Removal process：Before VAV status frames are received, renewal time stamp；Before VAV control frames are sent, during inquiry system
Between receiving the difference between timestamp, if difference is more than 30s, it is determined that it is overtime, its IP is write into 8 (that is, invalid addresses).
Terminate overtime recovery condition：Display board stops after reclaiming its IP address.
4) Parameter reconstruction and Conflict solving：
Trigger condition：Change display board.
Parameter reconstruction process：If the MAC mapping tables of display board are empty table, i.e. display board is brand-new, then is distributed in address
When inquire about IP address section, the IP of frame recording is applied in return address, returns to Modbus addresses, renewal Mac addresses, renewal time
Stamp, the flag bit that it is new display board is returned, receives Parameter reconstruction frame, is normally received and dispatched after sending acknowledgement frame.IP is arrived in VAV applications,
If detecting that the flag bit of new display board is effective, Parameter reconstruction frame is sent, is normally received and dispatched after receiving acknowledgement frame.If display
The MAC mapping tables of plate have record, then show that display board is previously used, and perform above-mentioned basic assigning process 1.
Terminate overtime recovery condition：Display board sends acknowledgement frame and the flag bit of new display board is set into invalid stopping.
By way of in upper example so that when air-conditioner set is installed into original air-conditioning network, can automatically derive ground
Location is communicated, it is not necessary to is manually configured, and when the air-conditioner set to break down is changed, can integrate the air-conditioning of script
