Multi-variable air conditioning unit comprises multiple air-conditioner set, and such as, the off-premises station shown in Fig. 1 and multiple indoor set, wherein, multiple indoor set comprises, indoor set 1, indoor set 2 to indoor set N.Multiple air-conditioner set is used for the routine data that reception program update device 10 is respectively broadcasted, and performs upgrading according to the routine data received.The routine data that off-premises station can be broadcasted by reception program update device 10 performs upgrading, and the routine data that indoor set also can be broadcasted by reception program update device 10 performs upgrading.
Preferably, multi-variable air conditioning unit and program upgrade apparatus 10 adopt the communication network topology of bus type, and program upgrade apparatus 10 and multiple air-conditioner set are all connected on communication bus 30 as communication apparatus node.
Fig. 2 is the schematic diagram of upgrading according to the program upgrade system performing a programme of the multi-variable air conditioning unit of the embodiment of the present invention, as shown in Figure 2, in this embodiment, for program upgrade apparatus 10, is described for program burn writing device 100.Multiple air-conditioner set comprises off-premises station, indoor set 1 to indoor set M, and indoor set M+1 is to indoor set N, and off-premises station and multiple indoor set are connected in parallel on communication bus.Because multiple air-conditioner set can distinguish the routine data of reception program update device 10 broadcast, thus improve the efficiency of transmission of data and the upgrading efficiency of multi-variable air conditioning unit.
Preferably, in embodiments of the present invention, the communication baud rate by adapting with communication network performs the transmission of data.The communication baud rate that between multi-variable air conditioning unit and program upgrade apparatus 10, data are transmitted adopts automatic network-building method to determine.In one embodiment of the invention, by the communication baud rate of the complexity determination multi-variable air conditioning unit transmission data of multi-variable air conditioning unit, the complexity of multi-variable air conditioning unit is higher, the communication baud rate of multi-variable air conditioning unit transmission data is lower, the complexity of multi-variable air conditioning unit is lower, and the communication baud rate of multi-variable air conditioning unit transmission data is higher.Because the communication network physical layer of multi-variable air conditioning unit and program upgrade apparatus 10 has multifarious feature, such as, when the quantity of multi-variable air conditioning unit is different with installation site, the physical layer complexity of the communication network of its composition is just inconsistent, when the communication network physical layer of air-conditioner set is comparatively simple, multi-variable air conditioning unit is with higher communication baud rate transmission data, thus the time of program on-line upgrading can be reduced, when the communication network physical layer of air-conditioner set is comparatively complicated, multi-variable air conditioning unit is with lower communication baud rate transmission data, the reliability of routine data transmission can be improved.So according to the actual requirements, select different communication baud rates at program upgrade apparatus 10, multi-variable air conditioning unit communicates with program upgrade apparatus 10 with polarity of communication by switching self baud rate, thus realizes the adaptive effect of communication baud rate.
