According to the barcode data, type variable is generated, and according to the running of the type Variable Control household electrical appliance.
Specifically, the physics bar code with model information is, for example, papery bar code, which can be according to specific coding
Rule forms bar code information.Bar code scanner 106 include bar code scanner and with matched first power supply of the bar code scanner.
After bar code scanner scans physics bar code, the electronic bar code with model information is obtained.
Electronic bar code includes two parts：The number-mark (number ID) and model information of product.
The coding rule of physics bar code is as follows：
A) first have to determine the data area of electronic bar code：It is converted into binary-coded decimal (Binary-Coded using by physics bar code
Decimal, binary-decimal code) storage mode, therefore the digit of binary-coded decimal is exactly the data bits of electronic bar code.Preferably
Ground, binary-coded decimal are no more than 32, if the coding ID of product is really more, can increase.It should be pointed out that in household electrical appliance 104
Inside the chip 800 (Microcontroller Unit, MCU) of electric-controlled plate, 2 binary-coded decimals one bytes of occupancy, therefore 32
Binary-coded decimal occupies the address space of 16 bytes.
B) the range of the number ID of its secondary calculation product：In one example, the data of 15 bytes, i.e., 30
Binary-coded decimal meets existing conventional coding, if 15 bytes are too many, can also be cut down according to actual conditions enough.
C to confirm a kind of quantity of the different type of machines of the number ID of product after), occupancy is corresponded in MCU800 to determine
Space.The corresponding bar code content of binary-coded decimal (2 binary-coded decimals) of current 1 byte is up to 99, can meet existing most
Demand.It is of course also possible to be increased according to actual conditions.
Therefore, in the present embodiment, electronic bar code is made of 32 binary-coded decimals, wherein preceding 30 binary-coded decimals indicate product
