The webserver 11 interrupts as the Long-distance Control of USB flash disk, it is connected with GPRS communication module 10 by wireless network, and inquiry terminal 12 preferentially adopts smart mobile phone, phone, notebook computer or panel computer to realize, it is connected with the webserver 11 by wireless network.
Embodiment 2
The present embodiment is the control method of wireless remote control accumulator system, and as shown in Figure 4, it mainly comprises the following steps:
(1) user is by inquiry terminal logging in network server, and sends short-message instruction to the webserver.MCU controller in the present invention 4 pairs of USB flash disk storeies 2 have following 4 kinds of patterns: forbid reading memory mode, recover to read memory pattern, format memory pattern and self-destruction memory mode.Therefore, user by wireless network to the short-message instruction that the webserver sends just be divided into can not reading command, recover reading command, formatting commands and command-destruct.
Can adopt the mode of low and high level to control when carrying out control signal controller for MCU controller 4, namely when MCU controller 4 output low level, signal controller is closed, and now USB flash disk reading data are normal; When MCU controller 4 exports high level, then signal controller controller opens, now signal controller disconnects USB flash disk data line, and computer just can not read USB flash disk data.
(2) short-message instruction is transferred to GPRS communication module by the webserver.When short-message instruction is sent to the SIM card in GPRS communication module by the webserver, it can adopt the networks such as 2G, 3G or 4G to realize.
(3) after GPRS communication module receives short-message instruction, by MCU controller, short-message instruction is converted into built-in command, and is transferred to signal controller and carries out processing.
Wherein, described " short-message instruction is converted into built-in command by MCU controller " specifically refers to: after MCU controller receives external messaging, resolve short message content and perform related command immediately, at this moment MCU controller exports different low and high levels by GPIO mouth, thus promote to forbid reading memory mode, recover to read memory pattern, format memory pattern and self-destruction memory mode, realize the long-range control to reservoir.
As mentioned above, just well the present invention can be implemented.
