[embodiment]
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 2, electronic system 2 according to one preferred embodiment of the present invention comprises the first functional module 21, second functional module 22 and connects the communication port 25 of the first functional module 21 and the second functional module 22.First functional module 21 has an input/output port 211, it is connected with the reset pin 221 in the second functional module 22.The first reset circuit 23 and the second reset circuit 24 of initial reset is carried out when this electronic system 2 comprises responsible system electrification further.In the present embodiment, the first reset circuit 23 is connected with the first functional module 21, and the second reset circuit 24 is connected with the second functional module 22.Certainly, in other embodiments, the first reset circuit 23 and the second reset circuit 24 can be designed to same reset circuit.
As shown in Figure 2, according to one preferred embodiment of the present invention, when electronic system 2 powers on, first, second reset circuit 23,24 resets to first, second functional module 21,22 respectively, makes electronic system 2 start normal work.Upon actuation, the first functional module 21 just inquires the second functional module 22 by communication port 25 every a setting-up time, and this setting-up time can freely be arranged.First functional module 21, according to the reply situation of the second functional module 22, judges whether the second functional module 22 normally works.If the second functional module 22 returns normal job information, then input/output port 211 does not do and reacts.If the second functional module 22 does not return normal job information or its return message represents that it does not normally work, then input/output port 211 sends the reset pin 221 in reset signal to the second functional module 22, second functional module 22 is resetted, makes the second functional module 22 restart normal work.Reset pin 221 can be designed to only when receiving input/output port 211 and transmitting reset signal, just once can reset to the second functional module 22.In alternative of the present invention, the reset circuit 24 of the second functional module 22 can omit, and directly carries out initial reset by the first functional module 21 to it.Now, when system electrification, by the first reset circuit 23, initial reset is carried out to the first functional module 21, first functional module 21 sends initial reset signal further by input/output port 211 to the reset pin 221 of the second functional module 22, carries out initial reset thus to the second functional module 22.
For a kind of Web TV, electronic system is made up of television module (being equal to first functional module 21 of Fig. 2), web download module (being equal to second functional module 22 of Fig. 2) and reset circuit (being equal to the first reset circuit module 23 of Fig. 2).Wherein television module and web download module have a serial ports passage (being equal to the communication port 25 of Fig. 2) to be connected, and television module input/output port (being equal to the input/output port 211 of Fig. 2) is connected with the reset pin (being equal to the reset pin 221 in Fig. 2) of web download module.Web download module in charge is the resource downloading on network to memory device, and television module then completes traditional TV functions.User when seeing TV, web download module can continue the resource in the download network of backstage.
Electronic system provides initial reset signal by reset circuit to television module when powering on, and television module carries out initial reset by television module to web download module after starting again.When web download module is downloaded on backstage, according to the reply situation of television module, television module just by serial ports multi-channel interrogation web download module, then judges that whether the duty of web download module is normal every a setting-up time.Sending reset signal when judging that web download module work is abnormal by input/output port to reset to web download module, allowing it recover normal work, and not affecting the normal work of television module.
The present invention further discloses a kind of repositioning method of electronic system.Wherein, first the first functional module 21, second functional module 22, first reset circuit 23 and the second reset circuit 24 shown in Fig. 2 be provided.Wherein, the first reset circuit 23 and the second reset circuit 24 are connected with the first functional module 21 and the second functional module 22 respectively.First functional module 21 is connected by a communication port 25 with the second functional module 22, and the input/output port 211 of the first functional module 21 is connected with the reset pin 221 of the second functional module 22.During system electrification, reset to respectively first, second functional module 21,22 by first, second reset circuit 23,24, make electronic system 2 start normal work.Subsequently, control the first functional module 21 and just inquire the second functional module 22 by communication port 25 every a setting-up time, this setting-up time can freely be arranged.Then, control the reply situation of the first functional module 21 to the second functional module 22 and judge, if the second functional module 22 returns normal job information, then input/output port 211 does not do and reacts; If the second functional module 22 does not return normal job information or its return message represents that it does not normally work, then input/output port 211 sends the reset pin 221 in reset signal to the second functional module 22, second functional module 22 is resetted, makes the second functional module 22 restart normal work.Reset pin 221, only when receiving input/output port 211 and transmitting reset signal, just once can reset to the second functional module 22.In alternative of the present invention, the reset circuit 24 of the second functional module 22 can omit, and directly carries out initial reset by the first functional module 21 to it.Now, when system electrification, by the first reset circuit 23, initial reset is carried out to the first functional module 21, first functional module 21 sends initial reset signal further by input/output port 211 to the reset pin 221 of the second functional module 22, carries out initial reset thus to the second functional module 22.
In the above-described embodiments, only to invention has been exemplary description, but those skilled in the art can carry out various amendment to the present invention without departing from the spirit and scope of the present invention after reading present patent application.
