Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of a method for storing locomotive wireless communication data according to an embodiment of the present invention, as shown in fig. 1, the method includes:
step S01, obtaining an address storage page group of each information type in an address area in the chip, wherein the address storage page group comprises address storage pages with preset page quantity, each address storage page at least stores address information, and the address information comprises a full flag bit and an end address.
During the maintenance of various operation information on the train, the operation information is classified into different information types according to the characteristics of information data, for example, key information, information sent by other equipment, information sent to other equipment, maintenance information, interaction information and the like are received and stored in a memory.
The embodiment of the invention adopts a Flash chip as a memory, and the chip is divided into a data storage area for storing various information data and an address area for storing address information according to different information types, wherein each information type corresponds to a unique data storage area respectively. For example, if there are 16 information types, the chip includes at least 16 data storage areas, and one address area. The address area stores therein address information in units of pages, each of which stores address information of one information type. Each information type corresponds to a preset number of pages, e.g. 6 pages, of address storage pages and address storage pages of the same information type may be combined into address storage page groups, i.e. each information type corresponds to one address storage page group.
The page location in the address area for each address can be divided according to actual needs, and only one of them is given as an example below. Take the 16 types of information as an example. The whole address area can consist of 100 pages, which are 0-99 pages respectively, and the address storage pages corresponding to each information type i are 16 x 0+ i-1, 16 x 1+ i-1, 16 x 2+ i-1, 16 x 3+ i, 16 x 4+ i-1 and 16 x 5+ i-1. That is, the address storage pages of the first information type are 0, 16, 32, 48, 64, 80, and the address storage pages of the second information type are 1, 17, 33, 49, 65, 81, … ….
The address information is composed of a full flag bit and an end address, wherein the full flag bit is located at a high position, and a specific length can be determined according to actual needs, for example, the full flag bit can be 2 bytes, and the end address is 4 bytes.
After the system is powered off and then powered on, since it is not clear where the received information data should be stored, it is necessary to first obtain the address storage page group of each information type from the address area.
Step S02 is to sort the address storage pages in each address storage page group according to the size of the value of the address information stored in each address storage page.
And respectively extracting address information stored in each address storage page group, and then sorting the address storage pages in each address storage page group according to the size of the address information.
Step S03, the address storage page where the minimum address information is located is used as the current address storage page of the corresponding information type, and the address information of the current address storage page is updated to the larger address information.
And defaulting an address storage page where the maximum address information is located as an address storage page used for storing the address information of the corresponding information type before the system is powered off, wherein an ending address in the maximum address information is the last address for storing the information data of the corresponding information type before the system is powered off, and the ending address is used as the starting address of the corresponding information type after the system is powered on.
And after the address storage page with the minimum address information in the address storage page group is started up at this time, the address information in the current address storage page is updated to the maximum address information in the address storage page group, wherein the current address storage page corresponds to the information type.
For example, after the computer is turned on, the address storage pages in which the first type of information is obtained in the address area are pages 0, 16, 32, 48, 64, and 80, respectively, where the address information stored in each page is shown in the following table:
| number of pages | Full of deposit flag | Ending address |
| Page 0 | 0 | 860 |
| 16 pages | 0 | 1467 |
| 32 pages | 0 | 360 |
| 48 pages | 0 | 2580 |
| 64 pages | 0 | 630 |
| 80 pages | 0 | 65432 |
According to the above table sorting 65432, 2580, 1467, 860, 630 and 360, it can be seen that the operation has been stored in the position of the data storage area 65432 corresponding to the information type last time, data is written from the position 65432 after the start-up this time, the data stored in the 32 nd page is found to be minimum this time, the 65432 is written into the 32 nd page first, and then the ending address stored in the 32 nd page is refreshed once every time one piece of service information is stored.
According to the embodiment of the invention, the address storage pages with the preset page number are distributed to each type of information to store the address information of the information data of the information type, and the current address storage page of each type of information is obtained according to the size of the address information value in each address storage page after each start-up, so that the address information of each type of information is stored in a polling mode among different address storage pages, the error possibility of the address information is reduced, and the safety performance of a train is improved.
Based on the above embodiment, further, after the step S03, the method further includes:
acquiring information data of various information types;
and writing the information data from the end address of the current address storage page in the data storage area uniquely corresponding to the information type according to the information type, and saving the last address written this time as the end address of the current address storage page of the information type.
After the current address storage page of each type of information type is determined, the chip can acquire a large amount of information data in real time, store the information data into the data storage area corresponding to the information type according to different information types, and start writing from the end address of the corresponding current address storage page in the data storage area.
And then after each storage, recording the last address written in the data storage area into the current address storage page in the corresponding information type to replace the end address in the current address storage page. And as time goes on, the ending address in the current address storage page is continuously refreshed according to the storage of the information data until the system is shut down or powered off.
According to the embodiment of the invention, the address storage pages with the preset page number are distributed to each type of information to store the address information of the information data of the information type, and the current address storage page of each type of information is obtained according to the size of the address information value in each address storage page after each start-up, so that the address information of each type of information is stored in a polling mode among different address storage pages, the error possibility of the address information is reduced, and the safety performance of a train is improved.
Based on the above embodiment, further, the address storage page includes address storage domains with a preset first backup number; correspondingly, each address storage page at least stores address information, specifically:
the address storage fields of each address storage page store the same address information.
In order to be able to increase the accuracy of the address information stored in each address storage page, each address storage page is divided into address storage fields of a preset first backup number, for example 5, wherein each address storage field stores address information and maintains synchronization.
After the chip finishes one-time information data storage, the last written address is sent to the corresponding current address storage page and is simultaneously stored in all the address storage domains to replace the end address. At this time, even if an error occurs in one of the address storage areas in the saved address information, calibration can be performed based on the address information in the other address storage areas to ensure accuracy each time the address information is extracted.
The division of the address storage domain in each address storage page may be performed according to actual needs, and only one of them is given as an example below. Taking 512 bytes per page as an example, dividing every 100 bytes into different address memory domains, saving address information from 0 byte, and then saving every 100 bytes, namely saving the same address information at the positions of 100 bytes, 200 bytes, 300 bytes and 400 bytes.
Based on the above embodiment, further, the address storage domain further stores a check bit.
Check bits, such as 2-byte CRC check bits, may also be added when saving address information. When the address information is extracted, whether the address information is accurate or not can be judged through the CRC check bit. If an error is determined, address information in other address storage domains may be extracted.
According to the embodiment of the invention, the address information of the information data of each type of information is stored by allocating the address storage pages with the preset page number to each type of information, and the current address storage page of each type of information is obtained according to the size of the address information value in each address storage page after each start-up, wherein the address storage pages simultaneously store the address information in the address storage domain of the preset first backup data, so that the address information of each type of information is stored in a polling mode among different address storage pages, the error possibility of the address information is reduced, and the safety performance of a train is improved.
Based on the above embodiment, further, the chip further includes backup address areas with a preset second backup number, each backup address area has a backup address storage page corresponding to each address storage page in the address area one to one, and real-time synchronization is maintained; accordingly, the method further comprises:
if the address storage page has a fault, acquiring the value of the address information in a backup address storage page corresponding to the address storage page in any backup address area; correspondingly, the step of taking the address storage page where the minimum address information is located as the current address storage page of the corresponding information type specifically includes:
and taking the address storage page where the minimum address information is located and the backup address storage page as the current address storage page of the corresponding information type.
In order to further increase the fault tolerance of the address information, the chip may further divide a backup address area with a preset second backup number, for example, 2. And the setting and the stored information of each backup address area and the address area are kept consistent. Each backup address area also comprises a backup address storage page corresponding to the information type, and each backup address storage page corresponds to the address storage page in the address area one to one.
When the address storage pages in the address storage page group of each information type in the address area are sorted each time the computer is started, the backup address storage pages in the backup address storage page group of each information type in each backup address area also need to be sorted. Thereby, the backup address storage page of the minimum address information is also used as the current address storage page of the corresponding information type. When the chip completes the storage of the information data, the address information needs to be saved in the current address storage pages of the address area and the backup address area.
If the address storage page of the address area has a fault or a storage error, the required address information can be acquired from the backup address storage page of the backup address area.
At this time, the chip will include 16 data storage areas and three address areas, one for one corresponding to the type of information. The division of the chip into each area may be performed according to actual needs, and only one of them is given here as an example, first, three address areas are drawn, and 100 pages are respectively used for storing address information of each type of information at the beginning position, middle position and end position of the chip. Then 16 data storage areas are divided from the rest space, and 50 pages of isolation space is reserved between each data storage area.
The embodiment of the invention stores the address information of the information data of each type of information by allocating the address storage pages with the preset page number to each type of information, and acquires the current address storage pages of each type of information according to the size of the address information value in each address storage page after each start-up, and the chip also comprises the backup address areas with the preset second backup number and the same content as the address areas, so that the address information of each type of information is stored in polling mode among different address storage pages, the error possibility of the address information is reduced, and the safety performance of a train is improved.
Based on the above embodiment, further, the method further includes:
and if the information data of the information type is written into the last address in the corresponding data storage area range, writing the subsequent information data from the address at the beginning in the data storage area range, and adding 1 to the full identification bit in the corresponding current address storage page.
The initial value of the full flag bit in the address information is 0, but in the process of continuously writing the information data into the data storage area, the data storage area tends to be saturated until the data storage area is full, at this time, a full signal may be sent to the current address storage page, and the full flag bit is incremented by 1. The information data acquired later will be written from the initial address of the data storage area again to overwrite the original information data. And after the data storage area is initially written to be full again, adding 1 to the full flag bit of the current address storage page again, and overwriting the data storage area from the initial address again.
According to the embodiment of the invention, the address storage pages with the preset page number are distributed to each type of information type to store the address information of the information data of the information type, and the current address storage page of each type of information type is obtained according to the size of the address information value in each address storage page after each start-up, so that the address information of the information type is stored in a polling mode among different address storage pages, the error possibility of the address information is reduced, and the safety performance of a train is improved.
