Description

TECHNICAL FIELD

[0001] The present application relates to the field of camera accessories, in particular to a high-speed camera data storage protection device. BACKGROUND

[0002] The high-speed camera memory card is a storage medium specially designed for high-speed cameras, used to record a large amount of image data generated during high-speed shooting. Its core feature is extremely fast read and write speed, which can match the high-frequency shooting requirements of high-speed cameras in a short time (such as shooting speed of hundreds to tens of thousands of frames per second), avoiding data loss or shooting interruption due to insufficient storage speed. The data writing process is triggered by shooting: after the high-speed camera is started, the sensor quickly captures the picture and generates image data; the data is first temporarily stored in the internal cache (such as DRAM) of the camera to ensure smooth shooting; the data in the cache is written to the storage grain (such as NAND flash) of the memory card at an extremely fast speed; by optimizing the file system (such as FAT32 / EXFAT) and interface protocol (such as UHS-II, CFexpress), the write delay is reduced; the memory card stores binary data (0 and 1) through flash memory grains (storage units composed of transistors); each unit can store 1 bit (SLC), 2 bits (MLC), or more data (TLC / QLC), and high-speed cards usually use SLC or MLC to ensure stability and speed; the card controller is responsible for managing the read and write paths of the data, balancing wear and tear (avoiding excessive use of certain blocks), and correcting errors (repairing data errors through ECC algorithm);

[0003] As for the patent of camera storage data protection, through retrieval, the Chinese patent with publication number CN217404865U discloses a high-speed camera protection storage data anti-disassembly device, which includes a circuit control module, an anti-disassembly wire and a Flash module, which are connected in sequence. The middle part of the anti-disassembly wire is fixedly connected with the rear cover of the high-speed camera. When the rear cover is not disassembled, it is recorded as state 1, the circuit control module is switched to the first power supply mode to provide 0V voltage for the Flash module, and the Flash module operates normally. When the rear cover is disassembled, it is recorded as state 2, the anti-disassembly wire is disconnected, the circuit control module is switched to the second power supply mode to provide breakdown voltage for the Flash module, and the Flash module is burned out. As a further optimization of the above-mentioned scheme, the circuit control module adopts a relay, and the positive electrode of the Flash module is connected with the NC end of the relay. As a further optimization of the above-mentioned scheme, the anti-disassembly wire includes a first connecting line, a second connecting line and a conduction line connecting the first connecting line and the second connecting line. The first connecting line and the second connecting line are movably connected with the conduction line. In the electrical output circuit, the controlled quantity has a predetermined step characteristic, the input voltage of the Flash module is adjusted until the Flash module is burned out, so as to achieve the protection purpose of the high-speed camera storage data. By arranging a relay 40 in the anti-disassembly device, when the change of the input quantity reaches the specified requirement, the controlled quantity has a predetermined step change characteristic in the electrical output circuit, the input voltage of the Flash module 30 is adjusted, so as to achieve the protection purpose of the high-speed camera storage data.

[0004] Although the anti-disassembly wire of the above-mentioned device can facilitate the disassembly of the rear cover, when the rear cover is violently damaged and disassembled, the first connecting line, the second connecting line and the conduction line are more likely to fall off and disconnect at the connection position, which facilitates the burning of the Flash module and enhances the protection purpose of the high-speed camera storage data, but in actual use, the current mainstream high-speed camera memory card usually does not directly provide a physical anti-disassembly structure, but is fixed through camera card slot design or external device. Criminals who involve private information can easily pull out the memory card in the camera without being found, without professional tools or cracking technology, and only basic physical operation is needed to complete data stealing, which reduces the attack threshold.

[0032] DETAILED DESCRIPTION Figures 1-8 The application provides a technical scheme: a high-speed camera protection data storage anti-disassembly device, which comprises an anti-disassembly sheet 1, a lock cylinder 2 is inserted into the anti-disassembly sheet 1, a lock sleeve 4 is arranged at the bottom of the lock cylinder 2, a mounting frame 3 is arranged at the bottom of the anti-disassembly sheet 1, a storage card sleeve 5 is arranged at the end of the mounting frame 3, a card groove 51 is formed in the inside of the storage card sleeve 5, a top plate 52 is fixedly arranged at the top of the storage card sleeve 5, a locking piece 11 is arranged on the surface of the top plate 52, the mounting frame 3 is installed on the storage card sleeve 5 through the lock sleeve 4.

[0033] Working principle: when in use, the device is particularly suitable for high-security cameras and is integrated into the memory card slot of the camera through the mounting frame 3. When the memory card needs to be removed, first use the special-shaped key 100 to insert it into the unlocking hole 22. At this time, rotate the force column 101, and the key 100 drives the force seat 21 to rotate. The force seat 21 can drive the lock column 24 to rotate, and the lock slot 26 rotates at the same time, so that the lock slot 26 is separated from the lock piece 43. At the same time, the lock piece 43 is arranged in the release area 261, and the three groups of lock pieces 43 are separated from the three groups of lock slots 26. At this time, the lock column 24 can be separated from the mounting frame 3, and the anti-disassembly piece 1 and the locking piece 11 are separated from the mounting frame 3, so that the locking piece 11 is separated from the surface of the top plate 52. At this time, the top of the card slot 51 has no blocking structure, and the storage card in the storage card sleeve 5 can be taken out. The three groups of lock pieces 43 need to be separated from the lock slots 26 at the same time to unlock, which increases the difficulty of illegal disassembly and prevents violent cracking. The linkage design of the anti-disassembly piece 1 and the locking piece 11 ensures that the storage card cannot be taken out without authorization and prevents malicious disassembly. The special-shaped key 100 and the unlocking hole 22 are specially matched to avoid opening with general tools and reduce the risk of copying. The key 100 rotates through the force column 101 and the force seat 21 to drive the lock column 24, the transmission path is clear, and the operation feedback is clear. The lock column 24 and the mounting frame 3 can be separated, which is convenient for replacing or maintaining damaged parts. The top of the card slot 51 has no blocking structure, which avoids hardware damage caused by forced card pulling. First, rotate the key 100 to remove the lock piece 43, then move the locking piece 11, and finally take out the card. The steps are rigorous to prevent accidental triggering. The lock piece 43 must be accurately separated from the lock slot 26 and moved to the release area 261 to unlock, which ensures the correctness of the operation. It is suitable for storage devices that require high security, such as financial and military data cards, and takes into account convenience and protection. Through multi-stage mechanical linkage and exclusive key 100 authentication, high-security storage card disassembly is realized at the physical level, with the characteristics of anti-disassembly, anti-misoperation and easy maintenance, which is suitable for scenes with strict data security requirements. When the camera's battery cover is opened, the memory card cannot be taken out without the key 100. Even if the battery cover is opened, the memory card is still fixed by the lock, and cannot be pulled out directly, effectively preventing data from being copied, deleted or implanted with malicious content. The "quick card pulling" attack can avoid instant theft of the memory card when the device is temporarily unattended. Without the key 100, professional tools are needed to crack the complex mechanical structure, which greatly reduces the success rate of theft. The complex card taking process can gain response time for device owners or security systems; the lock slot 26 and the lock piece 43 can be hidden inside the camera and cannot be directly contacted from the outside, avoiding violent disassembly; forced card taking may cause physical damage to the storage card sleeve 5 or the storage card, and the lock design forces the attacker to give up or leave obvious damage marks.Through mechanical structure, data security is deeply bound with device theft prevention, which significantly improves the anti-attack ability of the camera in the physical layer, especially suitable for professional fields with extremely high data security requirements;
