Method for storing washing machine identification code in tag memory
The present disclosure discloses a method for storing a washing machine identification code in a tag memory, the washing machine identification code being for indicating fabric information, the tag memory including an EPC memory for storing an electronic product code for identifying a tag object and a USER memory for storing user-defined data. The method includes: detecting a storage space remained of the EPC memory of the tag memory; storing the washing machine identification code into the EPC memory if the storage space is enough to store the washing machine identification code; otherwise, storing the washing machine identification code into the USER memory. Meanwhile, different writing priorities are used for different types of fabric attribute information in the storage process, thus ensuring that the electronic tag memory can completely and effectively store the key information of fabric attributes and meeting the requirement of smart washing of the washing machine.
1. A method for storing a washing machine identification code in a tag memory, the washing machine identification code being for indicating fabric information, the tag memory including an EPC memory for storing an electronic product code for identifying a tag object and a USER memory for storing user-defined data, comprising:
detecting a storage space remained of the EPC memory of the tag memory;
storing the washing machine identification code into the EPC memory if the storage space is enough to store the washing machine identification code;
storing the washing machine identification code into the USER memory if the storage space remained of the EPC memory is not enough to store the washing machine identification code.
2. The method according to claim 1 , wherein the fabric information indicated by the washing machine identification code comprises fabric attribute information, and priorities in a process of writing different fabric attribute information into the tag memory are different.
3. The method according to claim 2 , wherein the fabric attribute information comprises fabric material information, fabric color information, fabric category information, fabric specification information, and fabric manufacturer information; and
a priority order of writing the fabric attribute information into the tag memory is: fabric material information>fabric color information>fabric category information>fabric specification information>fabric manufacturer information.
4. The method according to claim 1 , wherein the method and the tag memory conform to the EPC Class1 Gen2 protocol.
5. The method according to claim 2 , wherein an encoding length of the washing machine identification code is 4-45 bits, and the fabric attribute information is written into the tag memory in order from high bit to low bit.
6. The method according to claim 5 , wherein the storage space of the tag memory is divided into different storage areas according to fabric attribute information, and capacities of storage areas occupied by various fabric attribute information are not completely same.
7. The method according to claim 6 , wherein in the tag memory, the fabric manufacturer information occupies 12 bits, the fabric specification information occupies 5 bits, the fabric category information occupies 6 bits, the fabric color information occupies 5 bits, and the fabric material information occupies 4 bits.
8. The method according to claim 1 , wherein the tag memory further stores a fabric factory internal code defined by a fabric manufacturer, and the fabric factory internal code is written into the tag memory with the washing machine identification code.
9. The method according to claim 8 , wherein a priority of writing the fabric factory internal code into the tag memory is lower than a priority of writing the washing machine identification code into the tag memory.
10. The method according to claim 1 , wherein the washing machine identification code is not be modified after being written into the tag memory.
11. The method according to claim 5 , wherein the encoding length is 32 bits.
12. The method according to claim 6 , wherein a relationship of capacities of storage areas occupied by various fabric attribute information is as following: fabric manufacturer information>fabric category information>fabric color information≥fabric specification information>fabric material information.
