Description

Technical Field

[0001] This invention belongs to the field of embedded data storage technology, and in particular, it relates to a method and system for monitoring and storing data in harsh environments. Background Technology

[0002] Embedded data storage is widely used in industrial monitoring and measurement fields. Local storage is crucial when "black box" data backup is used during monitoring and measurement, or when large amounts of data cannot be transmitted in a timely manner. Currently, data storage primarily relies on high-capacity FLASH chips, using the FatFS universal file system for easy storage and management. Data is extracted and analyzed when needed, mainly for data extracted at specific times. However, FLASH and similar storage devices are prone to widespread memory failures, data bit flips, and file information loss in harsh environments such as oil and gas exploration, aerospace, and high-temperature furnaces, leading to difficulties in effectively storing data. If even a few data bits are corrupted, the entire stored data may become unviewable and unretrievable. Summary of the Invention

[0003] The purpose of this invention is to address the problems of memory failure, data bit flipping, and file information loss that are prone to occur in harsh working conditions such as ultra-high temperature and strong radiation, making it difficult to effectively store data. This invention provides a storage method and system that is suitable for data recording in the field of monitoring and measurement under harsh working conditions such as ultra-high temperature and strong radiation.

[0004] The technical solution to achieve the purpose of this invention is as follows: On the one hand, a monitoring and data storage system suitable for harsh environments is provided, the system including a main control chip and data communication interface, a file data storage device, a file information storage device, and host computer dedicated storage management software;

[0005] The main control chip and data communication interface are used to realize data encoding and decoding, memory control and information transmission;

[0006] The file data storage device serves as the storage medium for monitoring data.

[0007] The file information storage device serves as a storage medium for file information generated when monitoring data is written to the file data storage device.

[0008] The dedicated storage management software for the host computer is used to receive data transmitted by the main control chip and to realize human-computer interaction operation control of the memory.

[0009] Furthermore, the main control chip at least implements high-speed error correction encoding and decoding, multi-chip co-location storage, multi-chip co-location reading, and data information correctness determination functions.

[0010] Furthermore, the file data storage device includes multiple storage chips. The main control chip first performs redundant error correction encoding on the monitoring data to be stored, and then simultaneously completes co-location storage writing on multiple storage chips.

[0011] Furthermore, when the monitoring data is stored in a file data storage device, the information used, including at least the block / sector storage unit, the corresponding sequence number, and the recording time, is used to form the file information.

[0012] Furthermore, the file information storage device includes multiple storage chips. The main control chip first performs redundant error correction encoding on the file information to be stored, and then simultaneously completes co-location storage writing on multiple storage chips. When transmission conditions are available, the data is transmitted to a remote storage device via a data communication interface for storage backup.

[0013] Furthermore, the dedicated storage management software for the host computer at least implements functions such as file information viewing, file downloading, file deletion, storage formatting, and bad block detection and marking.

[0014] Furthermore, the file information viewing includes viewing each block / sector storage unit used by the selected file and the corresponding time point; when downloading the file, it can adaptively select the storage content in the block / sector storage unit stored in a certain time period for download.

[0015] On the other hand, a method for storing monitoring data in harsh environments is provided, the method comprising the following steps:

[0016] After receiving the monitoring data, the main control chip first adds error correction coding to the monitoring data to be stored, and then simultaneously writes it to the file data storage device composed of multiple storage chips. When the monitoring data is written to the file data storage device, the file data storage device contains at least a set of information including storage units, writing time, and arrangement order to form file information.

[0017] The main control chip adds error correction coding to the file information and simultaneously writes it to the file information storage device composed of multiple storage chips; and when transmission conditions are available, the main control chip transmits the file information to a remote storage device for storage and backup through a data communication interface.

[0018] The host computer's dedicated storage management software manages the file data storage and file information storage, and at least enables functions such as file information viewing, file downloading, file deletion, storage formatting, and bad block detection marking.

[0019] Furthermore, the method also includes:

[0020] When the main control chip reads the stored content in the file data storage or file information storage, it simultaneously reads multiple storage chips and uses the herd mentality and error correction algorithm to obtain the correct monitoring data or file information data, which is then transmitted to the host computer's dedicated storage management software for display.

[0021] Furthermore, when the main control chip is unable to extract file information, the file information is obtained from the off-site storage.

[0022] Compared with the prior art, the significant advantages of this invention are:

[0023] (1) The present invention separates file information and file data. The amount of file information is very small, but the security requirements are extremely high. Higher-order error correction algorithms or file information can be transmitted to other locations for off-site storage to ensure the security of file information and maximize the extraction of file data, so as to effectively avoid the problem that the entire file data cannot be used when individual file information is damaged.

[0024] (2) The file information used in this invention can directly manage the underlying memory units. The memory units that are written have corresponding writing time information. It is particularly suitable for the form of writing and storing monitoring data in chronological order. When reading data, it can be extracted according to the file as needed, or it can be extracted by selecting only some storage units in the file according to time, which is more in line with the characteristics of the extraction and processing of monitoring data.

[0025] (3) The present invention proposes to add error correction encoding and decoding and co-location storage methods, which can effectively solve the problems that the memory and data are prone to chip failure and large-area data bit flipping under harsh environments such as ultra-high temperature and strong radiation, and can recover the original data to a greater extent.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description
