For the multi-connected central air conditioning system shown in fig. 1, the method for setting the air conditioning address includes, as shown in fig. 2:
step 201, a first line controller acquires a communication address of each indoor unit connected with the first line controller, wherein the communication address comprises a refrigerant system identifier of an outdoor unit connected with the indoor unit and an address identifier of the indoor unit in a refrigerant system of the outdoor unit connected with the indoor unit.
And the communication address of each indoor unit is randomly allocated to the indoor unit by the outdoor unit connected with the communication address. When the multi-connected central air-conditioning system is powered on, each outdoor unit automatically and randomly allocates addresses to all the indoor units connected with the outdoor unit, and the address information allocated to the indoor units connected with the outdoor unit by the outdoor unit comprises the refrigerant system identification of the outdoor unit and the address identification of the indoor units; the refrigerant system identification of the outdoor unit is used for indicating the identification of the outdoor unit connected with the indoor unit, the address identification of the indoor unit is the address identification of the indoor unit in the refrigerant system of the outdoor unit connected with the indoor unit, and the communication address of the indoor unit is determined by the refrigerant system identification of the outdoor unit and the address identification of the indoor unit. The identifier of the refrigerant system of the outdoor unit and the address identifier of the indoor unit may be represented by letters (e.g., a to Z, etc.), numbers (e.g., 1 to N, N is a positive integer, etc.), or a combination of letters and numbers.
In the embodiment of the present invention, the description is given by taking the example that the identifier of the refrigerant system where the outdoor unit is located and the address identifier of the indoor unit are both represented by numbers. Generally, each outdoor unit can be connected with 128 indoor units at most, so that the settable range of the 128 indoor units connected with each outdoor unit is X-1 to X-128; for example, assuming that each outdoor unit is connected to 30 indoor units at the same time, the settable range of each outdoor unit to the connected indoor unit is X-1 to X-128, where X is an identifier of a refrigerant system of each outdoor unit, and then each outdoor unit can randomly allocate a communication address to the connected indoor unit within the set range, and the communication address allocated to each indoor unit is not repeated. As shown in fig. 1, it is assumed that an outdoor unit 1 is connected to 5 indoor units, and communication addresses randomly allocated to the 5 indoor units by the outdoor unit 1 within a settable range are 1-1, 1-2, 1-3, 1-4, and 1-5 in sequence; the outdoor unit 2 is respectively connected with 5 indoor units, the communication addresses randomly distributed by the outdoor unit 2 in a settable range for the 5 indoor units are sequentially 2-6, 2-2, 2-3, 2-4 and 2-5, and so on, the outdoor unit N is respectively connected with M indoor units, and the communication addresses randomly distributed by the M indoor units in the settable range for the outdoor unit N are sequentially N-1, N-2, N-3, N-4, … … and N-M; further, the multi-connected central air-conditioning system also comprises at least one wire controller, each wire controller is connected with at least one indoor unit, as shown in fig. 1, the wire controller 1 is connected with an indoor unit 1-1, the wire controller 2 is connected with an indoor unit 1-2, the wire controller is connected with an indoor unit 1-3, the wire controller 4 is connected with an indoor unit 1-4, the wire controller 5 is connected with an indoor unit 2-6 and an indoor unit 2-2, the wire controller 6 is connected with an indoor unit 2-3, the wire controller 7 is connected with an indoor unit 1-5, an indoor unit 2-4 and an indoor unit 2-5, the wire controller N1 is connected with an indoor unit N-1 and an indoor unit N-2, and the wire controller NM is connected with an indoor unit N-M.
It should be noted that, the first line controller refers to any line controller in the multi-connected central air conditioning system, and is described in terms of standing on any line controller, and is not specific to a specific line controller, and each line controller controls the indoor unit connected to the line controller in order to reduce wiring. Meanwhile, each outdoor unit only performs address random allocation on the indoor units connected with the outdoor unit.
And step 202, determining whether the communication address of each indoor unit is the same as the preset physical address.
Specifically, the first line controller acquires a communication address of each indoor unit connected thereto, and compares the communication address of each indoor unit with a respective preset physical address to determine whether the communication addresses are the same. The indoor unit with the communication address different from the corresponding preset physical address is called a first indoor unit, namely the communication address of the first indoor unit is different from the preset physical address of the first indoor unit.
The preset physical address of the first indoor unit is a preset actual geographical position where the indoor unit is located. As illustrated in step 201, assuming that 5 rooms are arranged in the office area from east to west, 1 indoor unit is located in each room, and 5 indoor units are located in the refrigerant system of the same outdoor unit 2, the actual physical addresses of the 5 indoor units from east to west may be sequentially labeled as 2-1, 2-2, 2-3, 2-4, and 2-5. Because the communication address of the indoor unit 2-6 connected with the line controller 5 is different from the preset physical address 2-1, the indoor unit 2-6 connected with the line controller 5 is determined to be the first indoor unit. And determining whether the communication addresses of other outdoor units are the same as the preset physical addresses to determine the first outdoor unit.
Step 203, if the communication address of a first indoor unit in the indoor units is different from the preset physical address of the first indoor unit, changing the communication address of the first indoor unit into the preset physical address of the first indoor unit.
According to the example shown in step 201 and step 202, the line controller 5 needs to change the communication address of the indoor unit 2-6 to which it is connected to the preset physical address 2-1 so that the communication address corresponds to the physical address.
The embodiment of the invention provides a setting method of an air conditioner address, which comprises the following steps: the method comprises the steps that a first line controller obtains a communication address of each indoor unit connected with the first line controller to determine whether the communication address of each indoor unit is the same as a preset physical address, and if the communication address of a first indoor unit in the indoor units is different from the preset physical address of the first indoor unit, the communication address of the first indoor unit is changed into the preset physical address of the first indoor unit, so that the communication address of each indoor unit is the same as the preset physical address.
Further, for step 201, the acquiring, by the first line controller, the communication address of each indoor unit connected to the first line controller includes:
and 2011, the first line controller sends a connection information request to each indoor unit connected with the first line controller.
Step 2012, receiving first connection information sent by each indoor unit, where the first connection information is obtained by each indoor unit from an outdoor unit connected to the indoor unit, and the first connection information includes communication addresses of all indoor units connected to the outdoor unit.
Specifically, after the random address allocation of each outdoor unit to all the indoor units connected to the outdoor unit is completed, each outdoor unit sends first connection information to all the indoor units connected to the outdoor unit, where the first connection information is address allocation information of each outdoor unit to the indoor units connected to the outdoor unit, and the first connection information includes communication addresses of all the indoor units connected to the outdoor unit.
Further, the first line controller transmits a connection information request to all indoor units connected thereto, and the indoor units transmit address assignment information acquired from the outdoor units connected thereto as first connection information to the first line controller. If the first line controller is connected to at least two indoor units, and the indoor units are connected to different outdoor units, that is, the indoor units are connected to different refrigerant systems, the first line controller obtains connection information from a plurality of outdoor units (refrigerant systems).
Exemplarily, as shown in fig. 1, the outdoor unit 1 sends communication addresses of randomly allocated 5 indoor units connected to the outdoor unit 1 to the 5 indoor units (1-1 to 1-5), so that the indoor unit 1-1 obtains the communication addresses of its own indoor unit 1-2, indoor unit 1-3, indoor unit 1-4, and indoor unit 1-5, the indoor unit 1-2 obtains the communication addresses of its own indoor unit 1-1, indoor unit 1-3, indoor unit 1-4, and indoor unit 1-5, and so on; that is, each indoor unit acquires the communication address of other indoor units in the same outdoor unit as the indoor unit. For the line controller 7, the line controller 7 is simultaneously connected to the indoor units 1 to 5, the indoor units 2 to 4, and the indoor units 2 to 5, the line controller 7 sends connection information requests to the indoor units 1 to 5, the indoor units 2 to 4, and the indoor units 2 to 5, the indoor units 1 to 5 send the communication addresses of the indoor units 1 to 5 acquired from the outdoor unit 1 to the line controller 7, and simultaneously, the indoor units 2 to 4 and the indoor units 2 to 5 send the communication addresses of the indoor units 2 to 6 acquired from the outdoor unit 2 and the communication addresses of the indoor units 2 to 5 to the line controller 7, respectively, so that the line controller 7 acquires the communication addresses from the outdoor unit 1 and the outdoor unit 2 to the indoor units connected thereto.
Step 2013, according to the first connection information sent by each indoor unit, obtaining a communication address of each indoor unit connected with the first line controller.
In this way, according to the method described in step 2011 and step 2012, the first line controller can obtain the communication address of each indoor unit connected to the first line controller.
Further, although the address of each outdoor unit is randomly assigned to the outdoor unit connected thereto, the user cannot specify the communication address of each indoor unit, and in order to specify the communication address of each indoor unit, the first line controller may confirm the communication address of each indoor unit connected to the first line controller by the following method after acquiring the communication address. Specifically, the method comprises the following steps:
step 301, the first line controller sends a shutdown instruction to each indoor unit connected to the first line controller, so that each indoor unit connected to the first line controller executes a shutdown operation.
And 302, displaying the communication address of each indoor unit connected with the first line controller.
Step 303, receiving a selection instruction, where the selection instruction includes a communication address of any indoor unit selected from the displayed communication addresses.
And 304, sending a starting-up instruction to the selected indoor unit according to the selection instruction so as to enable the selected indoor unit to execute the starting-up operation, and enabling a user to determine the communication address of the indoor unit according to the starting-up operation of the indoor unit.
For example, as shown in fig. 1, the line controller 7 sends a shutdown instruction to the indoor units 1 to 5, 2 to 4, and 2 to 5 to enable the indoor units 1 to 5, 2 to 4, and 2 to 5 to perform a shutdown operation, the line controller 7 displays communication addresses of the indoor units 1 to 5, 2 to 4, and 2 to 5 in a shutdown state, a user may select one of the communication addresses of the indoor units 1 to 5, 2 to 4, and 2 to 5, assuming that the user selects the communication address of the indoor unit 1 to 5, the line controller 7 sends a startup instruction to the selected indoor unit 1 to 5 according to the selected communication address information of the indoor unit, at this time, the indoor unit 1 to 5 performs a startup operation, and the indoor units 2 to 4 and 2 to 5 are still in the shutdown state, thus, the user can confirm the communication address of the indoor unit according to which indoor unit is started. For the confirmation of the communication addresses of other indoor units, the indoor unit 1-5 may be turned off, or the confirmation may be performed according to the confirmation method of the communication addresses of the indoor units 1-5 without turning off the indoor units 1-5.
Further, the changing, by the first line controller in step 203, the communication address of the first indoor unit to the preset physical address of the first indoor unit specifically includes:
step 401, the first line controller determines whether the preset physical address of the first indoor unit is occupied according to the first connection information sent by each indoor unit.
If the preset physical address of the first indoor unit is not occupied, continuing to execute step 402-step 404; if the preset physical address of the first indoor unit is occupied, the steps 405 to 413 are continuously executed.
Step 402, sending a first address change request to the first indoor unit, so that the first indoor unit sends the address change request to an outdoor unit connected to the first indoor unit.
The first address change request may include a communication address of the first indoor unit, a preset physical address of the first indoor unit, and a preset identifier that the physical address of the first indoor unit is not occupied.
The outdoor unit determines whether to permit the change when receiving an address change request sent by the first indoor unit. If the change is allowed, a first change confirmation message is sent to the first indoor unit, and the first indoor unit sends the first change message to the first line controller, at this time, the first line controller may execute step 403 and step 404.
And step 403, within a preset time, the first line controller receives a first change confirmation message sent by the first indoor unit.
And sending the first change confirmation message to the first indoor unit by an outdoor unit connected with the first indoor unit.
And 404, changing the communication address of the first indoor unit into a preset physical address of the first indoor unit.
Further, after the address change is completed, the first line controller may display information of the completion of the address change so as to feed back to the user.
If the outdoor unit determines that the change is not allowed when receiving the address change request sent by the first indoor unit, the outdoor unit may not perform any operation, and thus, the first line controller may not receive a change confirmation message sent by the outdoor unit within a preset time, and then the first line controller determines that the change is failed, stops the change, and may feed back the change failure message to the user through the screen.
Step 405, sending a second address change request to the first indoor unit, so that the first indoor unit sends the second address change request to an outdoor unit connected to the first indoor unit.
The second address change request comprises a communication address of the first indoor unit, a preset physical address of the first indoor unit and a preset identifier that the physical address of the first indoor unit is occupied. When the outdoor unit connected to the first indoor unit receives the second address change request, the outdoor unit connected to the first indoor unit can specify which indoor unit the preset physical address of the first indoor unit is occupied by, according to the second address change request.
And 406, receiving the second change confirmation information sent by the first indoor unit within the preset time, where the second change confirmation information is sent to the first indoor unit by the outdoor unit connected to the first indoor unit.
When the outdoor unit connected with the first indoor unit allows change according to the second address change request, second change confirmation information is sent to the first indoor unit, the first indoor unit sends the second change confirmation information to the first line controller connected with the first indoor unit, and correspondingly, the first line controller receives the second change confirmation information.
Step 407, determining whether all communication addresses available for allocation in the outdoor unit connected to the first indoor unit are occupied.
If the communication addresses available for allocation in the outdoor unit connected to the first indoor unit are not occupied completely, execute step 408; if all the communication addresses available for allocation in the outdoor unit connected to the first indoor unit are occupied, step 409 is executed.
And 408, if the communication address of the first indoor unit is not occupied completely, changing the communication address of the first indoor unit into a first intermediate address, wherein the first intermediate address is any unoccupied communication address in the communication addresses which can be used for distribution in the outdoor unit connected with the first indoor unit.
And 409, if the indoor unit is completely occupied, changing the communication address of the first indoor unit into a second intermediate address, wherein the second intermediate address is a preset address which can be used for address change.
At this time, since the communication address of the first indoor unit is changed to an intermediate address (the intermediate address described herein may be a first intermediate address or a second intermediate address) that does not match the communication address in the outdoor unit connected to the first indoor unit, the outdoor unit connected to the first indoor unit obtains the intermediate address of the first indoor unit at this time, and changes the communication address of the first indoor unit in the first connection information to the intermediate address to obtain third connection information; further, the outdoor unit connected to the first indoor unit transmits third connection information, in which the communication address of the first indoor unit is an intermediate address, to the indoor unit (herein, referred to as a second indoor unit) occupying the physical address of the first indoor unit; further, the second indoor unit sends a reconnection request to a line controller (referred to as a second line controller herein) connected with the second indoor unit, the second line controller responds to the reconnection request, sends connection request information to the second indoor unit again, receives third connection information sent by the second indoor unit, and at this time, the second line controller changes the communication address of the second indoor unit into the communication address of the first indoor unit according to the third connection information; further, since the communication address of the second indoor unit is changed to the communication address of the first indoor unit and is not matched with the communication address in the outdoor unit connected to the second indoor unit, the outdoor unit connected to the second indoor unit acquires the changed communication address of the second indoor unit, and changes the communication address of the second indoor unit in the third connection information to the communication address of the first indoor unit to obtain second connection information, wherein the communication address of the first indoor unit in the second connection information is an intermediate address, and the communication address of the second indoor unit is the communication address of the first indoor unit; the outdoor unit connected to the second indoor unit sends the second connection information to the first indoor unit, and the first indoor unit sends a reconnection request to the first line controller connected thereto, and at this time, the first line controller continues to perform step 410.
It should be noted that the outdoor unit connected to the first indoor unit may send the second connection information to all indoor units under its refrigerant system, and of course, may also send the third connection information to all indoor units under its refrigerant system; meanwhile, the first indoor unit and the second indoor unit are in the same refrigerant system, so that the outdoor unit connected with the first indoor unit and the outdoor unit connected with the second indoor unit are the same.
And step 410, receiving a reconnection request sent by the first indoor unit.
And 411, sending the connection information request to the first indoor unit.
And the first wire controller responds to a reconnection request sent by the first indoor unit and sends a connection information request to the first indoor unit.
Step 412, receiving second connection information sent by the first indoor unit, where the second connection information is obtained by the first indoor unit from an outdoor unit connected to the first indoor unit, and the second connection information does not include a preset physical address of the first indoor unit.
And 413, changing the intermediate address of the first indoor unit to a preset physical address of the first indoor unit.
After the address change is completed, the outdoor unit connected with the first indoor unit obtains fourth connection information by resetting the communication addresses of all the indoor units connected with the outdoor unit, the outdoor unit connected with the first indoor unit sends the fourth connection information to the indoor unit connected with the outdoor unit, the indoor unit sends the reconnection information to the wire controller connected with the indoor unit, the wire controller responds and sends connection request information to the indoor unit connected with the wire controller, and the indoor unit connected with the wire controller sends the fourth connection information to the wire controller connected with the indoor unit.
In this way, if the preset physical address of the first indoor unit is not occupied, the correspondence between the communication address of the first indoor unit and the physical address can be realized through a direct change mode (namely, step 402-step 404); if the preset physical address of the first indoor unit is occupied, the correspondence between the communication address of the first indoor unit and the physical address can be realized through address swapping (i.e., steps 405-413).
In order to more clearly describe the above-described address change, an example will be described. As shown in fig. 1, the outdoor unit 2 is respectively connected to 5 indoor units, the addresses randomly allocated by the outdoor unit 2 to the 5 indoor units within a settable range are sequentially 2-6, 2-2, 2-3, 2-4 and 2-5, and the preset physical addresses of the 5 indoor units are sequentially 2-1, 2-2, 2-3, 2-4 and 2-5, so that the communication address of the first indoor unit (indoor unit 2-6) is different from the preset physical address, and the preset physical address 2-1 is not occupied, the line controller 5 sends a first address change request to the indoor units 2-6, the indoor units 2-6 send the first address change request to the outdoor unit 2, the outdoor unit 2 determines to allow change, sends a first change confirmation message to the indoor units 2-6, the indoor unit 2-6 sends a first change confirmation message to the line controller 5, and the line controller 5 changes the communication address of the indoor unit 2-6 to the preset physical address 2-1 according to the first change confirmation message.
As another example, if the outdoor unit 2 can be connected to 128 indoor units at most, as shown in fig. 1, 5 indoor units are actually connected to the outdoor unit 2, the communication addresses randomly allocated to the indoor units shown from left to right in fig. 1 are sequentially 2-4, 2-2, 2-3, 2-1, and 2-5 within a settable range, and the preset physical addresses of the 5 indoor units are sequentially 2-1, 2-2, 2-3, 2-4, and 2-5, wherein the communication addresses of the first indoor unit and the fourth indoor unit are different from the preset physical addresses, and the preset physical addresses are occupied by each other, so that the communication addresses of the first indoor unit and the fourth indoor unit can be exchanged. Specifically, the wire controller 5 sends a first address change request to the indoor units 2-4, the indoor units 2-4 send a second address change request to the outdoor unit 2, the outdoor unit 2 allows changing, and sends a second change confirmation message to the indoor units 2-4, the indoor units 2-4 send the second change confirmation message to the wire controller 5, and the wire controller 5 determines that all communication addresses (2-1 to 2-128) available for allocation in the outdoor unit 2 are not occupied, so that the wire controller 5 can change the communication addresses of the indoor units 2-4 to any communication address (2-1 to 2-128) available for allocation in the outdoor unit 2, which is not occupied.
