Example one
The embodiment provides an indoor unit address allocation method, which is applied to a multi-split system including an outdoor unit and at least two indoor units, as shown in fig. 1, and includes:
s101, when the multi-split system is powered on, the outdoor unit detects whether a first communication address is stored in the configured storage equipment.
Specifically, the outdoor unit and each indoor unit are respectively provided with a storage device, the storage device of the outdoor unit is used for storing a communication address of each indoor unit in the multi-split system, the storage device of each indoor unit is used for storing a communication address of each indoor unit, and the indoor units communicate with the outdoor unit through the communication addresses stored by the indoor units. In this embodiment, the storage device is a memory chip, and the memory chips are both disposed on the control main boards of the indoor unit and the outdoor unit, that is, the control main boards of the indoor unit and the outdoor unit are both control main boards carrying the memory chips.
And S102, if the first communication address is not stored, sending an allocation instruction to each indoor unit, and receiving a physical address code fed back by each indoor unit according to the allocation instruction.
Specifically, the physical address codes are carried by the indoor units, and the physical address codes of the indoor units are different, that is, the physical address code of each indoor unit has uniqueness. The physical address code can be a physical address of an indoor unit mainboard chip, and can also be a factory number of the indoor unit. In addition, when the communication address is not stored in the indoor unit, the indoor unit communicates with the outdoor unit through the physical address code. That is to say, when the communication address is not stored in the indoor unit, the indoor unit communicates with the outdoor unit through the physical address code, and the outdoor unit can acquire the physical address code and allocate the communication address according to the indoor unit corresponding to the physical address code.
And S103, distributing a second communication address to each indoor unit according to all the received physical address codes.
Specifically, the allocating the second communication address to each indoor unit according to the received all physical address codes may be sorting according to the physical address codes, and using the sorted serial number as the second communication address code; or generating the corresponding second communication address according to the physical address code, for example, selecting a part of each physical address code as the second communication address, and selecting different second communication addresses.
For example, the allocating a second communication address to each indoor unit according to all received physical address codes specifically includes:
s103a, sequencing all the received physical address codes according to a preset sequence, and sequentially distributing a second communication address to each indoor unit according to the sequencing sequence.
Specifically, the preset sequence may be arranged from small to large or from large to small. The sorting of all the physical address codes according to the preset sequence can be directly sorting the physical address codes, and can also be calculated, compared and sorted on the appointed data segments of the physical address codes. And after sequencing, acquiring the serial number of the physical address code, and taking the serial number as a second communication address, thereby simplifying the relatively complex physical address code of each indoor unit into simple sequence sequencing, embodying the uniqueness of each indoor unit, and facilitating the realization of efficient data interaction between the indoor unit and the outdoor unit.
Further, to avoid confusion of the communication address stored in the outdoor unit, step S103 may further include:
and S104, the outdoor unit updates the communication address in the configured storage equipment by adopting the second communication address.
Specifically, when a communication address is not stored in the outdoor unit, the second communication address is directly stored in the storage device; and when the communication address exists in the storage equipment, the storage equipment is emptied, and the second communication address is stored in the storage equipment, so that the communication address generated by the latest address allocation operation is only stored in the storage equipment, and the disorder of the communication address is avoided. Similarly, when each indoor unit receives the newly allocated second communication address, the storage device configured for the indoor unit is emptied, and the second communication address is stored in the storage device, so that the second communication address is used as the communication address for the indoor unit to communicate with the outdoor unit, and each indoor unit can be guaranteed to store only one communication address.
The embodiment provides an indoor unit address allocation method, which is used for acquiring a physical address code of each indoor unit when an outdoor unit does not store a communication address of the indoor unit, and allocating the communication address to the indoor unit according to the physical address code, so that the address is automatically allocated. Meanwhile, the problems of complex operation, easy error and low efficiency existing in the method for distributing the address to the indoor unit by manual operation are solved.
Example two
The present embodiment provides a method for allocating an address of an indoor unit, where the method is applied to a multi-split system including an outdoor unit and at least two indoor units, as shown in fig. 2, the method includes:
s201, when the multi-split system is powered on, the outdoor unit detects whether a first communication address is stored in the configured storage device.
Specifically, the indoor unit and the outdoor unit are the same as those in the first embodiment, and are not described herein.
And S202, if the first communication address is stored, receiving a physical address code sent by the indoor unit.
Specifically, the storing of the first communication address refers to that the outdoor unit stores a communication address of an indoor unit.
S203, if the physical address code is not received, receiving a third communication address sent by the indoor unit, and judging whether the received third communication address is not repeated.
Specifically, the non-reception of the physical address code indicates that a third communication address corresponding to the physical address code is stored in each indoor unit, and the communication with the outdoor unit is performed through the third communication address. Thus, when the indoor units communicate with the outdoor unit, the outdoor unit can acquire the third communication of each indoor unit. The judgment of whether the received third communication addresses are not repeated refers to the detection of whether each indoor unit stores address conflicts, so that the problem of communication faults caused by address conflicts can be avoided.
And S204, if the third communication address is repeated, executing the operation of sending the distribution instruction to each indoor unit so as to redistribute the communication address to each indoor unit.
Specifically, the third communication repeatedly indicates that the addresses stored in the indoor units conflict, so that the addresses need to be reassigned to each indoor unit, and the process of assigning addresses is the same as the assignment process in the first embodiment, and is not described here.
Further, the address allocation method for the indoor unit provided in this embodiment further includes:
s205, if the third communication address is not repeated, comparing the third communication address with the first communication address.
Specifically, the comparing the third communication address with the first communication refers to comparing the received third communication address of each indoor unit with all the first communication addresses stored in the storage device of the outdoor unit, so as to determine whether a communication address set formed by all the third communication addresses is consistent with a communication address set formed by all the first communication addresses.
And S206, if the first communication address is more than the third communication address, sending alarm information of missing indoor units.
Specifically, the first communication address is larger than the third communication address, which indicates that an indoor unit which is not in communication with the outdoor unit exists, and at this time, alarm information of indoor missing is sent. The alarm information may be transmitted through an indoor unit or an outdoor unit. The alarm information can be voice prompt, or text information sent to a preset device or a preset contact through a network.
And S207, if the first communication address is the same as the third communication address, monitoring an address-free alarm sent by the indoor unit, and sending alarm information for checking the connecting line when the address-free alarm is monitored.
Specifically, the indoor unit sends an address-free alarm to indicate that the indoor unit does not receive the communication address sent by the outdoor unit, which indicates that a problem may exist in the connection line between the outdoor unit and the indoor unit, and then sends alarm information for checking the connection line, so that a user can quickly locate the problem.
And S208, if the first communication address is less than the third communication address or the physical address code is received, executing the operation of sending an allocation instruction to each indoor unit.
Specifically, the first communication address is less than the third communication address, which indicates that the outdoor unit does not store the communication addresses of all the indoor units, and the received physical address code indicates that the indoor unit with the unallocated communication address exists. In both cases, addresses need to be allocated to the indoor units again, so that the outdoor unit stores the communication addresses of all the indoor units communicated with the outdoor unit, and normal communication is ensured.
In the method for allocating addresses to indoor units according to this embodiment, when the outdoor unit stores addresses of the indoor units, and the indoor units all communicate with the outdoor unit using the stored communication addresses, the outdoor unit determines whether the communication addresses of the indoor units conflict with each other after receiving the communication addresses carried by all the indoor units, and allocates addresses to the indoor units again when conflicts exist, thereby avoiding problems such as communication failure and confusion caused by communication address conflicts.
EXAMPLE III
The embodiment provides an indoor unit address allocation method, which includes the steps of the above embodiment, and in addition, the method further includes:
s301, receiving an operation of a user for modifying a communication address, and modifying the communication address in the storage equipment of the outdoor unit according to the operation;
and S302, sending the modified communication address to the indoor unit so that the indoor unit can update the communication address stored in the configured storage device.
In the method for allocating addresses to indoor units provided by this embodiment, after the allocation of addresses to indoor units is completed, a user can also query and modify the addresses of the indoor units by self-definition through the operation interface of the line controller, and the addresses of the outdoor host and the indoor units are updated synchronously when the addresses of the indoor units are modified; the address of the indoor unit can be manually re-allocated by setting the keys of the main board of the outdoor host machine or the operation interface of the wire controller, so that the requirements of various different conditions are met.
