Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the embodiment of the invention is described in further detail below in conjunction with the drawings and specific embodiments.
Embodiment one
Present embodiment provides a kind of engine display system restoration methods, as shown in Figure 1, comprising:
S10, whether after engine display starts, it is unusual to detect engine display system.
Whether described detection engine display system is specifically as follows unusually: whether the value that detects predeterminable area in the engine display system is correct.For example, after engine display plays machine, can write a fixed numeric values in a fixing flash zone, before entering engine display system, whether the numerical value that can detect this flash zone earlier is correct.
S20 is if then use the standby system file to cover the system file of engine display.
Please be simultaneously referring to Fig. 2, if engine display system is normal, execution in step S20 ' then: enter engine display system; If engine display system is unusual, then execution in step S20 writes the standby system file on the subregion of engine display system file, the system file that destroys before covering.
For the situation of the collapse of engine display system in the course of the work, the user can manually be restarted engine display system, to activate the testing process among the S10, also can be in system crash behind the Preset Time display restart automatically and activate testing process among the S10.
The engine display system restoration methods of present embodiment, take place when unusual in engine display system, by using the standby system file to cover the system file of engine display, realize the system file of fast quick-recovery engine display, ensure the operate as normal of engine display system, avoided because the serious consequences such as security incident that the engine display system collapse causes.
Embodiment two
Present embodiment is except the Overall Steps that comprises embodiment one, as shown in Figure 2, the method of present embodiment also comprises step S10a: judge at engine display to start to enter whether receive the instruction that enters recovery system in the engine display system process, if, S10b then: enter recovery system, if not, then continue step S10.
Wherein, recovery system can be arranged in engine display simultaneously with engine display system, also can be arranged in the autonomous device outside the engine display, and described standby system file can be stored in the described recovery system.
The described instruction that enters recovery system specifically can be imported by the specified button that the user pins on the keyboard, in the engine display system start-up course, keyboard driver can be loaded in the start-up routine to realize keypress function.
After entering recovery system, also comprise step S20a and S20b:
S20a recovers instruction if receive, and then uses the standby system file to cover the system file of engine display.Overlapping operation herein can be identical with step S20.
S20b if receive update instruction, then uses the system file of the new system file covering engine display in the External memory equipment.
The input mode of described recovery instruction and update instruction is with the described instruction that enters recovery system.
When existing engine display system was upgraded in the needs upgrading, because engine display is embedded on the driving position, serial ports and network interface were at the back side of engine display; If directly use serial ports and network interface that engine display system is upgraded, just engine display need be removed, just can download but also need computer to cooperate, very trouble.Present embodiment increases External memory equipment interface (for example USB interface, infrared interface or blue tooth interface etc.) by the front at display, realize using External memory equipment to carry new system file, described External memory equipment can be portable memory apparatus such as USB flash disk or portable hard drive.The new system file that External memory equipment carries is kept under the fixed schedule, after receiving update instruction, can use in the External memory equipment new system file under the fixing catalogue to cover the system file of engine display, makes the renewal process more convenient and quicker.
Described method also comprises step S20c: use the new system file in the External memory equipment to cover described standby system file.
In the said process, the sequencing that S20c and S20b do not have to carry out limits.
Cover the system file of engine display at described use standby system file after, described method also comprises step S30: restart engine display system.By restarting engine display system, can re-execute step S10, to activate testing process, guarantee the operate as normal of engine display system.
Present embodiment carries out unified management by recovery system to recovery and renewal, when needs recover or upgrade engine display system, can enter recovery system and carry out corresponding operating, both guarantee the steady operation of engine display system, can conveniently upgrade engine display system again.
Embodiment three
Present embodiment provides a kind of engine display system recovery device, and as shown in Figure 3, described device comprises:
Described device can also comprise: control module 300, and be used for starting and enter the engine display system process when receiving the instruction that enters recovery system at engine display, start recovery system.
If recovery system is positioned at the engine display system recovery device, then described device can also comprise memory module 400, is used to store described recovery system.Described memory module 400 can also comprise storage unit, is used to store described standby system file.
Described control module 300 can also be used for: when receiving the recovery instruction, call described overlay module 200 and use the standby system files to cover the system file of engine displays.
Described control module 300 can also be used for: when receiving update instruction, call the system file that described overlay module 200 uses the new system file covering engine display in the External memory equipment.
Described control module 300 also is used for: call described overlay module 200 and use the new system file of External memory equipment to cover described standby system file.
The engine display system recovery device can be integrated in the engine display, also can be used as the device that is independent of engine display.
The engine display system recovery device of present embodiment, take place when unusual in engine display system, by using the standby system file to cover the system file of engine display, realize the system file of fast quick-recovery engine display, ensure the operate as normal of engine display system, avoided because the serious consequence that the engine display system collapse causes; By using recovery system that unified management is carried out in recovery and renewal, when needs recover or upgrade engine display system, can enter recovery system and carry out corresponding operating, both guarantee the steady operation of engine display system, can conveniently upgrade engine display system again.
