Description
Technical field
This utility model relates to technical field of data security, more specifically, relates to the device of a kind of safety storage, this dress
Put the safety that ensure that transmission data when external equipment carries out data communication with acquisition terminal.
Background technology
At present, it is more and more that law-enforcing recorder or mobile phone etc. use, along with the function of law-enforcing recorder or mobile phone etc. is got over
Coming the most complicated, a lot of law-enforcing recorders or mobile phone all use the general-purpose platforms such as Android, Linux as operating system, and this just adds
The big safety problem odds such as virus, hacker.Once there is safety problem in law-enforcing recorder or mobile phone, is turning back to collection
After terminal, it is possible to network or individual PC to law enforcement agency threaten.Therefore, it is necessary to make improvements.
Utility model content
In order to overcome the deficiency in the presence of prior art, it is provided that a kind of simple in construction, safe and convenient, data are transmitted more
Safe and reliable device.
In order to solve above-mentioned technical problem, the technical scheme that this utility model is used is:
The device of a kind of safety storage, including host CPU module, FLASH memory module, telecommunication management chip and contactor
Control module, described host CPU module and telecommunication management chip are respectively by contactor control module with FLASH memory module even
Connecing, described telecommunication management chip is connected with the USB interface of acquisition terminal, and described contactor control module can monitor USB interface
Connected state.
When described host CPU module is connected with FLASH memory module, FLASH memory module disconnects with telecommunication management chip；Institute
Stating FLASH memory module when being connected with telecommunication management chip, host CPU module disconnects with FLASH memory module.
Described telecommunication management chip can realize USB device end agreement, communicates with acquisition terminal, and stores FLASH
Data in module carry out checking and by USB interface, its data being sent to acquisition terminal.
Described device is law-enforcing recorder.
Described device is mobile phone.
Compared with prior art this utility model is had the beneficial effect that
Telecommunication management chip of the present utility model is only connected, with it with the FLASH memory module of law-enforcing recorder or mobile phone
He does not has annexation at module, and in separate state, function is only and judges the legitimacy of data in FLASH memory module, therefore, and this
Utility model can ensure that storage part will not be polluted by rogue program, prevents rogue program from causing collection after entering acquisition terminal
Terminal or background server and the destruction of office network.
Accompanying drawing explanation
Below by accompanying drawing, detailed description of the invention of the present utility model is further described in detail.
Fig. 1 is structural representation of the present utility model.
In figure: 1 be host CPU module, 2 for FLASH memory module, 3 for telecommunication management chip, 4 for contactor control mould
Block, 5 it is USB interface.
Detailed description of the invention
Example below combines accompanying drawing and is further described this utility model.
As it is shown in figure 1, the device of a kind of safety storage, including host CPU module 1, FLASH memory module 2, telecommunication management core
Sheet 3 and contactor control module 4, described host CPU module 1 and telecommunication management chip 3 are respectively by contactor control module 4
Being connected with FLASH memory module 2, described telecommunication management chip 3 is connected with the USB interface 5 of acquisition terminal, described contactor control
Molding block 4 can monitor the connected state of USB interface 5；When described host CPU module 1 is connected with FLASH memory module 2, FLASH deposits
Storage module 2 disconnects with telecommunication management chip 3；When described FLASH memory module 2 is connected with telecommunication management chip 3, host CPU module 1
Disconnect with FLASH memory module 2；Described telecommunication management chip 3 can realize USB device end agreement, communicates with acquisition terminal,
Storage FLASH can be accessed after USB inserts, the data in FLASH can be checked when accessing FLASH, only allow to close
Advise, normal, safe audio, video data is sent to acquisition terminal.
In this utility model, USB interface is not directly connected to host CPU, makes unsafe data not directly to be transmitted；
Adding a telecommunication management chip 3, telecommunication management chip 3 and other parts are independent, and its function is only and judges in FLASH
The legitimacy of data, and legal data are sent to USB；Add a contactor control module 4, can control
The data access side of FLASH, this switch first determines whether and monitors the state of USB interface 5, switches according to the state of USB interface 5 and opens
Close, after inserting USB interface 5, no longer allow the host CPU access to FLASH, reduce the transmission of dangerous data.
