Abstract
The invention discloses a fault automatic recovery system and a method thereof, which are suitable to an electronic device. The system at least comprises an external module, application software and adevice driver. An application program is used for receiving the data transferred by the external module; the device driver is positioned between the external module and the application software and i s used for initializing the external module and monitoring the data transferring status of the external module. The external module does not send the data when being detected over a preset time, the device driver restarts the external module.
Description
Technical field
The present invention is for a kind of fault automatic recovery system being provided, particularly a kind of automatic recovery system of the external module that resets automatically.
Background technology
Application software and external module be in the process of data transmission in the known electronic, sees through a driver usually as each other bridge, but when the unusual phenomenon of external device (ED) appearance in the process of running; Upper application software just can't normally be used relevant function, will wait until usually after a period of time, and the user finds the unusual of application software and restarting systems or external module; Could recover, for example, in global position system; When satellite positioning module takes place can't send data unusually; Navigation software just can't carry out navigation action, and must wait until the user to find the unusual of navigation software and restarting systems could be recovered normally, and such action can empty the interior almanac data of internal memory usually simultaneously; And need to wait for long positioning time after causing starting shooting again, cause user's inconvenience.
Therefore; For solving the above-mentioned problem that proposes, the inventor is based on going in for the study and many practical experience, through research and design and special topic are inquired in many ways for many years; Then a kind of fault automatic recovery system and method are proposed, with as aforementioned expectation one implementation and foundation in the present invention.
Summary of the invention
Because above-mentioned problem; The object of the invention is for providing a kind of fault automatic recovery system; Particularly a kind of data transmission state that sees through driver monitoring external module, when stopping to send data when the external module failover, the automatic recovery system of the external module that can reset automatically.
For reaching above-mentioned purpose, according to fault automatic recovery system of the present invention, be applicable to an electronic installation, it comprises an external module, an application software module and a driver module at least.Application program module is to receive the data that external module transmitted; Driver is between external module and application software; In order to the initialization external module; And the state of monitoring external module transmission data, when external module does not send data above a Preset Time, be to restart external module.
Hold the above,, see through the data stream that driver monitoring external module sends data to application software because of according to fault automatic recovery system of the present invention and method; When surpassing a Preset Time and all not receiving the data from external module, judge that just the state of external module is undesired, initiatively it is restarted; Effective elevator system fiduciary level; Externally module takes place can recover automatically when unusual, and driver restarts is the inner firmware of external module, but not restarts fully; Thoroughly empty the data in the internal memory, the system that makes can resume operation in the shortest time.
Description of drawings
Fig. 1 is the calcspar that shows fault automatic recovery system of the present invention.
Fig. 2 is the calcspar that shows the preferred embodiment of fault automatic recovery system of the present invention.
Fig. 3 is the flow chart of steps that shows automatically restoring fault method of the present invention.
Fig. 4 is the flow chart of steps that shows the preferred embodiment of automatically restoring fault method of the present invention.
Embodiment
Below will fault automatic recovery system and method according to preferred embodiment of the present invention be described with reference to correlative type, wherein identical assembly will be explained with identical reference marks.
Seeing also Fig. 1, is the calcspar that shows fault automatic recovery system of the present invention, is applicable to an electronic installation, and it comprises an external module 11, an application software module 13 and a driver module 12 at least.Application program module 13 is to receive the data 14 that external module 11 is transmitted; Driver module 12 is between external module 11 and application software module 13; In order to initialization external module 11; And the state of monitoring external module 11 transmission data, when external module 11 does not send data above a Preset Time, be to restart external module 11.
Wherein, The said external module is preferably a satellite positioning module; Above-mentioned application software module is preferably a navigation software module; Above-mentioned driver module is preferably a serial driver module, and above-mentioned driver module is to see through the firmware of initial external module again, to restart external module.
Seeing also Fig. 2, is the calcspar that shows the preferred embodiment of fault automatic recovery system of the present invention, like diagram; Because driven in series program 22 is positioned at the middle layer, can monitor the satellite location data 24 that comes up by satellite positioning module 21 transmission, after satellite positioning module 21 initialization are accomplished; Can initiatively and lose satellite location data 24 continuously and give the upper strata; So, the data stream situation that transmits at driven in series program 22 observe satellites locating modules 21, whether state that just can judge module is normal.Under satellite positioning module 21 situation in proper working order, be expected in cycle regular time and can receive relative data volume at least, even do not having under the enough satellite signals intensity; Satellite positioning module 21 still can transmit related data, therefore, if interior driven in series program 22 of a period of time is not all received the data from satellite positioning module 21 continuously; Just it is undesired to look its state, then initiatively with its Reset, and the Reset here; The firmware of just initial again satellite positioning module 21 inside; And equally can thoroughly empty the internal storage data unlike Factory Reset, and make satellite almanac data also deleted, thus; Can in the shortest time, let satellite positioning module 21 can recover and locate completion again, make and reduce to minimum for the influence of upper strata navigation software 23.
Seeing also Fig. 3, is the flow chart of steps that shows automatically restoring fault method of the present invention, and its step is as back:
Step S31 a: application software is provided;
Step S32: see through a driver initialization one external module, driver is between application software and external module;
Step S33: see through application software and receive the data that external module transmitted; And
Step S34: seeing through the state of driver monitoring external module transmission data, when external module does not send data above a Preset Time, is to restart external module.
Wherein, The said external module is preferably a satellite positioning module, and above-mentioned application software is preferably a navigation software, and above-mentioned driver is preferably a serial driver; Above-mentioned driver is to see through the firmware of initial external module again, to restart external module.
Seeing also Fig. 4, is the flow chart of steps that shows the preferred embodiment of automatically restoring fault method of the present invention, and its step is as back:
Step S41: initial navigation software;
Step S42: open COM port;
Step S43: driven in series program initialization satellite positioning module;
Step S44: whether the monitoring satellite positioning module surpasses a Preset Time is not sent data, if execution in step S45 if not, then continues monitoring; And
Step S45: the firmware of initial again satellite positioning module.
