Abstract
The invention relates to an automatic update method of data, in particular to the data update in a memorizer of a video device. The invention is to resolve the problem of providing a method that the memorizer has automatic update data after the upgrade of the software. The adopted technical proposal comprises the following steps: a. first starting of the whole machine, the version number of the software is stored in the memorizer; b. when the whole machine is started every time, the version number of the software in the default data area is compared with the version number of the software in the memorizer, thus entering into step c if both are identical or entering into step d if both are different; c. the data in the memorizer is read; d the data in the memorizer is renovated immediately and the version number of the software in the default data area is stored in the memorizer. The invention has the advantages of simplicity, easy and reliable operation and greatly improving the production efficiency of product and the eligibility rate of opening the box of whole machine.
Description
Technical field
The present invention relates to a kind of data automatic update method, particularly the Data Update in the storer of video equipment.
Background technology
On electronic equipments such as televisor, video disc player, often adopt storer to carry out the data in real time storage, so that when starting shooting next time, canned data when but the software quick calling was shut down last time, such as the size of volume, the analog quantity of image, data message such as startup channel, current frequency makes complete machine specified channel that enters last time rapidly and the analog quantity that needs.
When complete machine is produced,, often need upgrade again to software in order to revise software error or to increase relevant new function.
The present data refresh mode of sort memory after software upgrading, adopt manual control to upgrade:
Normally by RS232 mouth or VGA mouth, after the software upgrading, complete machine, will no longer refresh storer when in detecting storer data being arranged in order to save the on time like this in the software upgrading of storer; Start once more, the data of store memory storage before the data that master chip calls remain, data can not upgraded automatically along with the renewal of program.
In software upgrade process, data read-write operation may cause the default data mistake of calling after the start to data generation maloperation in the storer.Institute thinks the assurance program correctness, and the complete machine that software upgrading is finished need carry out the operation that data empty in the storer usually, so that complete machine detects and do not have data in the storer, comes that storer is carried out the default data again and is provided with; Avoid the relevant issues that error in data causes in the storer with this.
When adopting the aforesaid operations mode on production line, to debug, need use a teleswitch, every complete machine is set to factory mode come updated stored device data, can spend more debug time like this and produce and do over again; And if after the workover rig upgrading, also may face same problem, particularly Wai Bu maintenance personal may not know more new data or how to upgrade, and software upgrading still has some data and mistake can occur like this, and it is undesired to cause the complete machine start to show.
Summary of the invention
Problem to be solved by this invention is that the method for a kind of storer automatically updating data after software upgrading is provided.
The present invention solves the problems of the technologies described above the technical scheme that is adopted to be, memory data automatic update method may further comprise the steps:
A, complete machine are started shooting first, and software version number is stored in the storer;
B, complete machine are started shooting at every turn, and the software version number in default data district and the software version number in the storer are compared, and as identical, enter step c; As inequality, enter steps d;
C, the data in the storer are read;
D, immediately the data in the storer are refreshed, and the software version number in default data district is deposited in the storer.
Have two bytes store software version number in the allocate memory.
The invention has the beneficial effects as follows, the start judgement time is shorter, refresh rate to storer is fast, hardware there is not special requirement, the relevant issues that error in data causes in the storer of having avoided taking place after the software upgrading, a large amount of a debugging job and a maintenance difficult problem have been avoided in the operation of realization sort memory automatically updating data simultaneously, and be simple, implement reliably to have improved the unpacking qualification rate of production efficiency of products and complete machine greatly.
Description of drawings
Fig. 1 is a process flow diagram of the present invention.
Embodiment
The automatic update scheme of memory data of the present invention's proposition is based on the basis of all circuit common, utilizes the software version number after upgrading preceding different with upgrading, by the differentiation of program increase to data in the storer, can realize that memory data upgrades automatically; Avoid abnormal default setting of indivedual complete machines by testing result.Simple, the enforcement easily of detection method, the judgement time is short, does not bind with the function of chip, has high cost performance.The storer that is commonly used to deposit real time data at present is EEPROM.
This embodiment uses chip model 24LC16 as EEPROM, and the memory capacity of this chip is 2KByte, link to each other with master chip (model is MST718) by the 3.3V universal serial bus, flow process as shown in Figure 1:
During software upgrading, the computer expert crosses plug-in frock, and 66 pin, 67 pin that use serial 232 buses to connect master chip MST718 write ROMPaq.Master chip MST718 inside does not have program ROM, when writing a program, by special clock and data line, directly program is write among the plug-in program FLASH, promptly this plug-in FLASH is the default data district, after writing journey and finishing, system restart, software version number in new software version number among the calling program FLASH and the EEPROM relatively, when being checked through software version number and changing, promptly refresh the total data information of EEPROM and the version number of software redaction is stored in the FF position, promptly be stored in last 2 bytes of EEPROM.As not changing, then do not refresh data in the EEPROM.Major cycle is read data in the EEPROM again.
Be applicable to video equipments such as computer, televisor, DVD, can detect software version by Automatic Program whether to change, control whether to the EEPROM automatically updating data.
Claims (4)
1. memory data automatic update method is characterized in that, may further comprise the steps:
A, complete machine are started shooting first, and software version number is stored in the storer;
B, complete machine are started shooting at every turn, and the software version number in default data district and the software version number in the storer are compared, and as identical, enter step c; As inequality, enter steps d;
C, the data in the electrical storage are read;
D, immediately the data in the storer are refreshed, and the software version number in default data district is deposited in the EEPROM (Electrically Erasable Programmable Read Only Memo).
2. memory data automatic update method automatic update method according to claim 1 is characterized in that, two bytes store software version number in the allocate memory.
3. memory data automatic update method automatic update method according to claim 1 is characterized in that described storer is EEPROM.
