The specific embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is done further description.

The present invention proposes a kind of method to set up of central air conditioner system address of indoor unit, and the solution conventional art need take resources of chip and the on-the-spot problem that inconvenience is set in a large number to the set-up mode of address of indoor unit.As shown in Figure 1, the method to set up of the central air conditioner system address of indoor unit among the present invention may further comprise the steps: a. transfers to test mode with the indoor set remote controller, and each indoor set is sent unique, different test patterns; B. each indoor set receives and resolves test patterns, and it as this machine address, is stored to memory cell; Address information when each indoor set is started shooting c. in the reading cells, and be in holding state; D. indoor set has judged whether that remote control receives, and is execution in step e then, otherwise execution in step g; E. judging whether this remote control receives is test mode, is execution in step f then, otherwise execution in step g; F. receive and resolve new test patterns, with it as this machine address, the storage and the updated stored unit in address information; G. with the test patterns information in the memory cell as this machine address.

Embodiment:

This example is that the address of indoor unit with the large-scale central air conditioner system with 128 indoor sets is set to example.In general, the indoor set remote controller has normal state of a control and test mode, and we are provided with the employing test mode to address of indoor unit here.Because the excursion of test patterns is 0-200, the address that therefore can satisfy 128 indoor sets fully is provided with requirement.At first first indoor set sent test patterns " 1 ", indoor set acceptance test sign indicating number is stored to memory cell (such as EEPROM) after resolving, with the address of this test patterns " 1 " as this TV station indoor set.Then again second indoor set sent test patterns " 2 " ... Finish until whole setting of 128 address of indoor unit.After this indoor set is in when start, the address information in the reading cells at first, and be in the wait accepting state, if there is not remote control signal reception, just with original address stored information as address of indoor unit.If remote control signal reception is arranged; Will then judge whether it is test mode, if not test mode, still with original address stored information as address of indoor unit; If the time test mode; Just showing has new test patterns to upgrade, and so just new test patterns is resolved the back as address of indoor unit, and is stored to the test patterns that memory cell is replaced former preservation.
