Describe with reference to the accompanying drawings according to the storage means of the data of the embodiment of the present invention.
As shown in Figure 2, the storage means of the data of the embodiment of the present invention comprises the following steps:
S201, obtains N byte in the FLASH of control chip for storage data.
In one embodiment of the invention, as shown in Figure 3, can adopt the FLASH302 of control chip 301 self of the control panel of household electrical appliance to carry out data storage for example stores the power-off parameter of household electrical appliance, control chip 301 self with FLASH302 conventionally have larger storage space, more than 16K byte, be generally for example 16*1024=16384 byte, wherein can preserve fixing routine data by 12K byte, and remaining 4K byte can be used for for example power-off parameter of household electrical appliance of save data.So can obtain N byte in the FLASH302 of control chip 301 for the storage data power-off parameter of household electrical appliance for example.The value of N can be in one embodiment of the invention: N=2200, obtains 2200 bytes store power-off parameters in FLASH302.After obtaining N byte, enter step S202.
S202, is divided into a group storage space by N byte, and wherein, every group of storage space comprises two memory paragraphs, and the first memory paragraph is for storing erasable number of times of this group storage space, and the second memory paragraph is used for storing data.
After step S201 obtains individual for example 2200 bytes of N in FLASH302, N byte is divided into a group storage space, every group of storage space comprises two memory paragraphs i.e. the first memory paragraph and the second memory paragraph, wherein, the first memory paragraph is for storing erasable number of times of this group storage space, and the second memory paragraph is used for storing data.Power-off number of parameters that general household electrical appliance need to be preserved is limited can not surpass 20 bytes.The value of a can be in one embodiment of the invention: a=100.For example 2200 bytes are divided into 100 groups of storage spaces, every group of storage space comprises 22 bytes, wherein 2 bytes can be used as the first memory paragraph, for storing erasable number of times of respective sets storage space, remaining 20 bytes can be used as the second memory paragraph and for storing data, for example store the power-off parameter of household electrical appliance.After N byte being divided into a group storage space, can be by power-off Parameter storage in the second memory paragraph of every group of storage space, but, because the erasable number of times that repeats of every group of storage space of FLASH302 only has 10,000 times, so need to judge that this group storage space whether can data writing according to the data of the first memory paragraph of every group of storage space, enter step S203.
S203, reads the data of the first memory paragraph in every group of storage space.
Because the erasable number of times that repeats of every group of storage space of FLASH302 only has 10,000 times, so need to judge whether data to be write to this group according to the number of times of every group of storage space, need to read the data of the first memory paragraph in every group of storage space, and enter step S204.
S204, judges whether the data of the first memory paragraph are less than preset times.
In one embodiment of the invention, preset times can be 10,000 times, it is the erasable number of times of FLASH302, in other words, at step S203, read after the data of the first memory paragraph of every group of storage space, whether the data that judge the first memory paragraph are less than 10,000 times, when for example the first memory paragraph data are less than 10,000 times when the data of the first memory paragraph are less than preset times, enter step S205.
S205, is stored in data in the second memory paragraph of this group storage space, and the data of controlling in the first memory paragraph of this group storage space add one.
At step S204, judge that the data of the first memory paragraph are less than preset times for example 10,000 times time, the data of needs storage are stored in the second memory paragraph of this group storage space, simultaneously, after in the second memory paragraph that data is stored in to this group storage space, the data of controlling in the first memory paragraph of this group storage space add one, represent that the data storage number of times of this group storage space in the data space of FLASH302 has increased once.
It should be noted that, when needing for example power-off parameter of save data at every turn, all need to read by step S203 the data of the first memory paragraph in every group of storage space, and judge by step S204 whether the data in the first memory paragraph are less than preset times for example 10,000 times, and when the first memory paragraph is less than preset times, by step S205 by data for example power-off Parameter storage in the second memory paragraph of this group storage space, and the data of the first memory paragraph of this group storage space are added to one.In addition, in one embodiment of the invention, as shown in Figure 4, also comprise the steps:
S401, when the data of the first memory paragraph equal preset times, judges whether this group storage space is last group storage space.
At step S204, judge that the data of the first memory paragraph equal preset times for example 10,000 times time, the erasable number of times that represents this group storage space is full, cannot store again data, judge whether this group storage space is last group in a group storage space, say, whether the erasable number of times that judges a group storage space is all full, if so, enters step S402.If not, this group storage space is not last group in a group storage space, in other words, in a group storage space, also have other erasable number of times less than storage space group, enter step S403.
S402, a group storage space of FLASH cannot be stored data again.
S403, read this group storage space next group storage space the first memory paragraph data and judge whether the data of the first memory paragraph are less than preset times.
If it is not last group of a group storage space that step S401 judges this group storage space, be in a group storage space, also have erasable number of times less than storage space group, read the data of the first memory paragraph of next group storage space of this group storage space, and whether the data that judge this first memory paragraph be less than preset times for example 10,000 times, return to step S204.So circulation, until the erasable number of times of a group storage space in FLASH302 is all expired, FLASH302 cannot store data again.
Can find out, although a of the FLASH302 of control chip 301 group storage space for example in 100 groups the erasable number of times of every group of storage space be preset times for example 10,000 times, but by change data at FLASH302 the memory location at 100 groups of storage spaces, can make the storage number of times of data reach 1,000,000 times of EEPROM, reach the object of using the FLASH302 simulation EEPROM storage data that control chip 301 carries.In storage data full in the situation that, can also provide prompting so that user knows in FLASH302 has write 1,000,000 times.
In one embodiment of the invention, as shown in Figure 5, the storage means of above-mentioned data also comprises:
S501, judges that whether a group storage space is for storing first data.
At equipment, after for example household electrical appliance power on, first judge that a group storage space of FLASH302, whether for storing first data, if store first data, enters step S502, if not storing first data, return to step S203.
S502, every group of storage space controlling a group storage space carries out initialization.
If a group storage space in step S501 judgement FLASH302 is for carrying out first data storage, control every group of storage space and carry out initialization, the first memory paragraph and the second memory paragraph that are about to every group of storage space all carry out assignment zero, carry out zero clearing to facilitate data storage.At every group of storage space controlling a group storage space, complete after initialization, if storage data are returned to step S203.
In sum, according to the storage means of the data of the embodiment of the present invention, by adopting the FLASH of control chip to carry out data storage, can reduce costs, and the storage space of FLASH is divided into a group storage space, by changing data in the memory location of a group storage space, thereby the number of times that can improve the erasable data of FLASH for example can reach the erasable number of times 1,000,000 times of EEPROM storage.The data poke method of the embodiment of the present invention, in the cost-effective while, has improved the reliability of product.
