Step S104, main frame receive the identity information that the first slave distributes instruction return according to address.Wherein, the first slave For any one slave in slave unit.
Step S106, main frame generate the address to be allocated for giving the first slave according to the identity information of return.
Specifically, main frame automatically generates the address to be allocated to corresponding first slave according to the identity information received. When including multiple slaves in slave unit, each slave distributes instruction according to the address of host broadcast and returns to identity information extremely The identity information returned respectively according to each slave is automatically address corresponding to the generation of each slave by main frame, main frame.
Step S108, main frame send address to corresponding first slave.
Using the embodiment of the present invention, the main frame in air-conditioner set connects after being instructed to the distribution of slave unit broadcast address The identity information that the first slave (some slave in such as slave unit) distributes instruction return according to the address is received, then basis The identity information generates the address to be allocated for giving the first slave, and the address of the generation is sent to corresponding first slave, from And realize and distribute address automatically for slave.It is main when multiple slaves be present in slave unit by the above embodiment of the present invention Machine is respectively that each slave distributes address automatically, so as to realize each slave distinguished in slave unit, without in the prior art Extra increase device, and extra increased device is set manually, so as to solve in the prior art when air-conditioner set , it is necessary to be set manually during the project installation of air-conditioner set when using RS485 buses progress data communication between distinct device Toggle switch, cause the technical problem that installation effectiveness is low, the distinct device realized as air-conditioner set distributes the effect of address automatically Fruit, improve the installation effectiveness of air-conditioner set.
Further, by the above embodiment of the present invention, without increasing the difference that extra device can be air-conditioner set Equipment distributes address automatically, can reduce product cost.
According to the above embodiment of the present invention, the main frame in air-conditioner set distributes instruction to slave unit broadcast address Afterwards, above-mentioned method can also include：
Step S1, main frame judge whether to get the identity information that the first slave distributes instruction return according to address.
Wherein, judge to get the first slave not successfully according to the identity information of address distribution instruction return in main frame In the case of, perform step S2；Judge that successfully get the first slave believes according to the identity of address distribution instruction return in main frame In the case of breath, the step S104 to step S108 in above-described embodiment is performed.
Step S2, the distribution instruction of main frame repeated broadcast address, and judge whether that get the first slave distributes according to address Instruct the identity information returned.
Specifically, judge to get the situation for the identity information that the first slave returns according to address distribution instruction in main frame Under, perform the step S104 to step S108 in above-described embodiment；Otherwise, return and perform step S2.
It should be further stated that if main frame is distributed in repeated broadcast address after instructing preset times (such as 5 times), The identity information of the first slave return is still got not successfully, then judges that the first slave has got the address of host assignment.
Specifically, when including multiple slaves in slave unit, each slave distributes in the address for receiving host broadcast , all can be to identity information corresponding to host response itself, because part slave may be in the same time to main frame after instruction Identity information is replied, this will cause data overlap, and main frame None- identified goes out the identity information that the part slave returns.But always The time for having part slave to host response identity information staggers, and in this case, main frame can recognize slave The identity information of return.Replied that is, main frame always receives at least one slave (such as the first slave) in slave unit Identity information.
In this embodiment, in order to ensure the address that all slaves in slave unit can get host assignment, Main frame is needed after each broadcast address distributes instruction and completes address batch operation, the distribution instruction of repeated broadcast address；When When having the address that slave does not get host assignment in slave unit, the slave will return to identity information to main frame, so that main Machine can be that the slave distributes address automatically；When all slaves in slave unit have all got the address of host assignment, that Main frame will not receive the identity information of slave return, and now, main frame will continuously (such as 5 times) repeated broadcast address refers to for several times Order.When main frame, continuously (preset times described above) all do not get the identity information of the first slave return successfully for several times, That is there is no the address distribution instruction of slave response main frame in slave unit, at this point it is possible to judge the institute in slave unit There is the address that slave has got host assignment, now, address allocation procedure will terminate automatically.
By the above embodiment of the present invention, it can confirm that whether all slaves in slave unit have all got main frame point The address matched somebody with somebody, it is that it distributes address in the case where there is slave not receive the address of host assignment, does not have for several times continuously in main frame In the case of having the identity information for successfully getting slave return, it may be determined that whole slaves have all got the ground of host assignment Location, so as to which all slaves being embodied as in slave unit distribute address automatically.
In the above embodiment of the present invention, identity information of first slave according to address distribution instruction return is received in main frame Before, above-mentioned method can also include：
Step S3, the first slave judge whether there is the address for being used for identifying the first slave.
Wherein, in the case where the first slave is judged not having for identifying the address of the first slave, step S4 is performed To step S5；Judge in the first slave in the case that there is the address for being used for identifying the first slave, perform step S6 extremely Step S8.
Step S4, the first slave generation identity information.Wherein, identity information includes at least one following information：Identity is believed The check code of the frame head of breath, the identity recognition number of the first slave and corresponding address distribution instruction.
The identity information of generation is sent to main frame by step S5, slave.
Specifically, the frame head of the first slave identity-based information, itself identity recognition number (such as identification ID) and The corresponding check code of instruction is distributed with the address that it is received, generates identity information.First slave sends the identity information of generation To main frame, to perform subsequent step, the address of host assignment is obtained.
Alternatively, can be that each slave (such as line control machine) write-in is unique raw in the production process of air-conditioner set Bar code is produced, in this, as the identification ID of slave.
In the case where the first slave has the address for being used for identifying the first slave, the first slave does not return to identity letter Breath is to main frame, and now, main frame will perform step S6 to step S.
Step S6, main frame, which performs, to be judged whether to get the identity information that the first slave returns according to address distribution instruction Step.
Specifically, perform step S6 because the first slave does not return to identity information to main frame, main frame and will determine that out not successfully The identity information that the first slave distributes instruction return according to address is got, now, continues executing with step S7 to step S8.
Step S7, the distribution instruction of main frame repeated broadcast address, and judge whether that get the first slave distributes according to address Instruct the identity information returned.
Step S8, if main frame is distributed in repeated broadcast address after instruction preset times, first is still got not successfully The identity information that slave returns, then judge that the first slave has got the address of host assignment.
Specifically, step S7 to step S8 implementation is consistent with step S2 implementation, will not be repeated here.
By the above embodiment of the present invention, the slave with address no longer responds the address distribution of host broadcast and referred to Order, chance is provided so as to not get the slave of the address of host assignment yet for other, is obtaining ground between reduction slave Competitiveness during location, to ensure that all slaves in slave unit can smoothly get the address of host assignment.
According to the above embodiment of the present invention, the ground to be allocated for giving the first slave is generated according to the identity information of return in main frame Before location, above-mentioned method can also include：
Step S9, the identity information that main frame returns according to the verification slave of code check first.
Step S10, if the identity information that the first slave returns, by verification, main frame is according to the identification of the first slave Number generation address to be allocated for giving the first slave.
Specifically, the validity that verifies the code check identity information of the main frame in the identity information received, and should In the case of verification code check is successful, the identity information of the first slave return is judged by verification, now main frame is according to first Identity recognition number (such as identification ID) in the identity information of slave automatically generates the address to be allocated to first slave.
Pass through the above embodiment of the present invention, it can be ensured that corresponding address is distributed automatically for slave, so that it is guaranteed that from The address between each slave in machine unit is different, in the running of follow-up air-conditioner set, it is ensured that can distinguish Each slave in slave unit, without increasing additional devices in the prior art, product cost is both reduced, and without setting manually Extra increased device is put, the effect for distributing address automatically for all slaves in slave unit is realized, so as to improve sky The installation effectiveness of unit is adjusted, simplifies the installing engineering of air-conditioner set.
Fig. 2 is the flow chart of the address distribution method of another air-conditioning equipment according to embodiments of the present invention, such as Fig. 2 institutes Show, this method may include steps of：
Step S202, the address distribution instruction of the first slave Receiving Host broadcast in the slave unit in air-conditioner set. Wherein, the multiple slaves included in slave unit belong to same communication network with main frame, and the first slave is in slave unit Any one slave.Specifically, it is powered first after air-conditioner set installation, will be empty automatically into address allocation flow The main frame in unit is adjusted to distribute each Slave Broadcast address into slave unit to instruction.
Alternatively, when main frame is the indoor set in air-conditioner set, slave is line control machine；When main frame is in air-conditioner set During outdoor unit, slave is the indoor set in air-conditioner set.
Step S204, the first slave judge whether to receive the address of host assignment.
Step S206, if the first slave does not receive the address of host assignment, the first slave is to host response identity Information.Specifically, the first slave generates identity information after address distribution instruction is received, wherein, identity information is included such as At least one lower information：The verification of the frame head of identity information, the identity recognition number of the first slave and corresponding address distribution instruction Code；Identity information is sent to main frame by random times of first slave after identity information is generated.
It should be further stated that after the first slave distributes instruction in the address for receiving host broadcast, if its The address of host assignment is not yet received, random communication tupe will be entered：The address distribution instruction of main frame is responded, based on body The frame head of part information, itself identity recognition number (such as identification ID) and with the address corresponding school of distribution instruction that it is received Code is tested, generates the identity information of first slave, and a certain moment after address distribution instruction is received is by the body of generation Part information is sent to main frame.
Alternatively, can be that each slave (such as line control machine) write-in is unique raw in the production process of air-conditioner set Bar code is produced, in this, as the identification ID of slave.
In this embodiment, due to each slave in slave unit at random to main frame send identity information, partly from Machine may be in the same time to host response identity information, and this will cause data overlap, main frame None- identified go out the part from The identity information that machine returns.But the time for always having part slave to host response identity information staggers, in this feelings Under condition, main frame can recognize the identity information of slave return.That is, main frame is always received at least one in slave unit The identity information that individual slave (such as the first slave) is replied, and generate address corresponding with the identity information.
Step S208, the address that the first slave Receiving Host distributes according to identity information.Specifically, the first slave preserves ground Location；First slave to host response confirmation, wherein, confirmation be used for indicate the first slave be correctly received address. In this step, the first slave preserves the address received, and to host response confirmation (confirmation of such as shaking hands), with logical Know that main frame first slave has been properly received the address of host assignment, the automatic address distribution of first slave is i.e. complete Into.
It should be further stated that confirmation is used to show that the first slave is correctly received main frame as its automatic point The address matched somebody with somebody, its particular content and form can specify according to program development design agreement, and this is not limited by the present invention.
Using the embodiment of the present invention, the address of the first slave Receiving Host broadcast in the slave unit in air-conditioner set is divided With instruction, and judge whether to have been received by the address of host assignment, in the case of the address of host assignment is not received by, to Host response identity information, so that main frame automatically generates the address of first slave according to the identity information, and Receiving Host is pressed According to the address of identity information distribution, it is achieved thereby that distributing address automatically for slave.By the above embodiment of the present invention, work as slave When multiple slaves in unit be present, main frame is respectively that each slave distributes address automatically, is distinguished so as to realize in slave unit Each slave, set manually without additionally increasing device in the prior art, and to extra increased device, so as to solve In the prior art when using RS485 buses to carry out data communication between the distinct device of air-conditioner set, it is necessary in air-conditioner set Toggle switch is set manually during project installation, causes the technical problem that installation effectiveness is low, realizes as air-conditioner set not Distribute the effect of address automatically with equipment, improve the installation effectiveness of air-conditioner set.
Further, by the above embodiment of the present invention, without increasing the difference that extra device can be air-conditioner set Equipment distributes address automatically, can reduce product cost.
According to the above embodiment of the present invention, in step S204, the first slave judges whether to receive the address of host assignment Afterwards, if the first slave is judged to receive the address of host assignment, the first slave is not to host response identity information.
