B, indoor set calculate the CRC8 of a generation byte according to sequence code and are attached to aforementioned identifiers and are sent to off-premises station together, this string numeral is carried out sequencing numbers and sends it back indoor set according to agreement by off-premises station, indoor set stores this numbering as address, and off-premises station stores total quantity as indoor set number of units.
Further, register control procedure to comprise:
A1, initiation login state: outdoor controller initiates registration, indoor set receives initiation registration and enters address registration state;
A2, search sequence code: off-premises station is initiated login state time delay and entered search sequence code state after 5 seconds, and indoor set receives the search sequence code order of off-premises station, the sequence code inquiry of response off-premises station;
A3, address assignment: off-premises station receives correct indoor set sequence code response, carries out sequencing numbers and numbering is sent back to indoor set; Indoor set receives this numbering and stores as the address be assigned to, and enters address acquisition wait state;
A4, address assignment complete detection: off-premises station enters transmission address assignment and completes detection after completing and inquiring about from the CRC CRC8 of 00H ~ FFH; After indoor set receives orders, detect whether have address;
A5, address assignment complete: off-premises station sends and is assigned sense command.Then the state of being assigned is entered without interior machine response; Indoor set enters normal operating condition after receiving and being assigned order.
Preferably, initiate login state: off-premises station interval 100ms sends and initiates log-in command, and indoor set receives the address registration order of off-premises station, enters address registration state, according to the sequence code calculating cyclic redundancy check code CRC8 of 8 bytes;
Search sequence code: after off-premises station enters search sequence code state, sends search sequence code; Indoor set receives the search sequence code order of off-premises station, replys, otherwise do not reply when the CRC8 that analysis judgment receives is identical with the CRC8 calculated;
Address assignment: off-premises station receives correct indoor set sequence code response, enters address assignment state, sends allocation address order to the machine of corresponding CRC8; The indoor set that corresponding CRC8 is identical with sequence code receives the address assignment order of off-premises station, and address acquisition also stores, and waits for that the address registration of outer machine enters normal operating condition after completing order;
Address assignment completes detection: off-premises station enters transmission address assignment and completes sense command lasting 5 seconds after completing and inquiring about from the CRC CRC8 of 00H ~ FFH; If there is response, reenter initiation login state;
If nonreply, enter address assignment and complete the stage; Continuous 10 take turns initiation registration still has interior machine to reply zero-address, and compulsory withdrawal is registered; Indoor set receive off-premises station be assigned sense command after, interior machine testing has zero-address, and the interior machine of allocation address does not process, and does not have the interior machine of allocation address to continue response;
Address assignment completes: after off-premises station enters address assignment completion status, inquires about machine in allocation address by platform;
Indoor set receive off-premises station be assigned order after, interior machine enters normal operating condition.
Further, described sequence code at least comprises 6 bytes; In byte 1, Bit0 is month data, and Bit1 ~ Bit7 is time data; In byte 2, Bit0 ~ Bit3 is date data, and Bit4 ~ Bit7 is month data; In byte 3, Bit0 ~ Bit2 is minute data, and Bit2 ~ Bit7 is hour data; In byte 4, Bit0 ~ Bit3 is data in second, and Bit4 ~ Bit7 is minute data; In byte 5, Bit0 ~ Bit5 is random data, and Bit5 ~ Bit7 is data in second; In byte 6, Bit0 ~ Bit7 is random data.
Further, when again receive under login state initiate log-in command time advanced row sequence code each byte add 1 after calculating cyclic redundancy check code CRC8 again.
The present invention utilizes existing internal-external machine RS485 communication network, the mode linked by indoor and outdoor machine, realizes automatically distributing and registration address of indoor unit function, and easy and simple to handle, success rate is high.
Accompanying drawing explanation
Fig. 1 is the control procedure schematic diagram of present pre-ferred embodiments;
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described.
The main outer machine of a kind of air-conditioning one many machines indoor address distribution method, first utilize computer by current time, be accurate to year, month, day, hour, min, second, the random number of adding 2 sends to indoor set controller as login ID, and indoor set controller is stored into EEPPROM after receiving the identifier of 8 bytes; Then indoor set produces the CRC8 of a byte according to this string identifier calculation and is attached to aforementioned identifiers and is sent to off-premises station together, this string numeral is carried out sequencing numbers and sends it back indoor set according to agreement by off-premises station, indoor set stores this numbering as address, and off-premises station stores total quantity as indoor set number of units.
The unique sequence code of indoor set generates and sends when carrying out production test and stores to indoor set controller.
Sequence code at least comprises 6 bytes, and its content is followed successively by:
Byte1：
