Embodiment
Fig. 1 is the schematic diagram of a kind of electronic installation according to embodiments of the invention, please refer to Fig. 1.Electronic installation 100 comprises timing unit 102 and CPU (central processing unit) 104, and timing unit 102 couples CPU (central processing unit) 104.Timing unit 102 does not belong to a part for CPU (central processing unit) 104, even if CPU (central processing unit) 104 crashes or cannot normal operation, timing unit 102 all can normal operation.Wherein electronic installation 100 can be such as desk computer, notebook computer or server, network equipment ... etc., so not as limit.Timing unit 102 can such as be implemented with microcontroller or 555 timers, timing unit 102 in order to timing, and in order to export reset signal RS1 when timing reaches Preset Time to CPU (central processing unit) 104, to restart CPU (central processing unit) 104.Wherein Preset Time can be set greater than the time started needed for CPU (central processing unit) 104, for example, if it is 30 seconds that CPU (central processing unit) 104 restarts the required time, then Preset Time such as can be set as that 30 seconds, 40 seconds or 1 minute (so not as limit) etc. are greater than the time of 30 seconds, time enough is had to restart to allow CPU (central processing unit) 104, avoid causing the midway that CPU (central processing unit) 104 is carrying out restarting to be reset again, and forever cannot complete the situation restarted.CPU (central processing unit) 104 in order to receive the system update instruction from far end device, can be carried out the operation of software upgrading and is again activated, or is activated in order to the enabled instruction received from far end device.Wherein far end device can be such as desk computer, notebook computer or server ... etc., so not as limit.
When CPU (central processing unit) 104 normal operation, CPU (central processing unit) 104 can in order to maintain preset state by the look-at-me ITR1 exporting timing unit 102 to, carry out time timing to interrupt timing unit 102, allow timing unit 102 timing cannot reach Preset Time and to send reset signal RS1.And between the starting period of CPU (central processing unit) 104, though CPU (central processing unit) 104 cannot continue because not yet completing startup to export look-at-me ITR1, so because Preset Time has been set to be greater than the time started needed for CPU (central processing unit) 104, the situation crashed if therefore do not occur between the starting period of CPU (central processing unit) 104, when completing the startup of CPU (central processing unit) 104, timing unit 102 not timing reaches Preset Time.So, CPU (central processing unit) 104 just can maintain the look-at-me ITR1 of preset state to timing unit 102 in order to output before timing unit 102 exports reset signal RS1, and avoid timing unit 102 to send reset signal RS1, and then successfully can complete the initiating task of electronic installation 100 or the operation of software upgrading.
On the contrary, if there is the situation crashed in CPU (central processing unit) 104 between the starting period, CPU (central processing unit) 104 cannot complete startup before timing unit 102 timing reaches Preset Time, also namely cannot export before timing unit 102 timing reaches Preset Time and maintain the look-at-me ITR1 of preset state to timing unit 102.So, when timing unit 102 timing reaches Preset Time, timing unit 102 just in order to send reset signal RS1 to CPU (central processing unit) 104, and can restart CPU (central processing unit) 104, avoid electronic installation 100 to be in deadlock state constantly, and cause the puzzlement of user.Wherein, timing unit 102 can in order to the timing Preset Time that repeatedly circulates, so, if the factor causing CPU (central processing unit) 104 to crash cannot be got rid of by single time restart, also be the situation that CPU (central processing unit) 104 crashes once more when being restarted between the starting period, and when causing timing unit 102 timing to arrive Preset Time, timing unit 102 also again can send reset signal RS1 and reset CPU (central processing unit) 104.So by timing unit 102 repeatedly circulation timing Preset Time, can when crashing appears in CPU (central processing unit) 104 continuously, repeatedly reset CPU (central processing unit) 104, until CPU (central processing unit) 104 return to can normal operation state and export the look-at-me ITR1 with predetermined period sustainably.Similarly, if there is the situation crashed at other times point in CPU (central processing unit) 104, and cannot export maintain preset state look-at-me ITR1 to timing unit 102, also send reset signal RS1 to reset CPU (central processing unit) 104 by timing unit 102, make its return to can normal operation state and till exporting the look-at-me ITR1 with predetermined period sustainably.
Fig. 2 A is the waveform schematic diagram of the look-at-me according to one embodiment of the invention, and Fig. 2 B is the waveform schematic diagram of the reset signal according to one embodiment of the invention.Please also refer to Fig. 2 A, for example, above-mentioned look-at-me ITR1 can be such as periodic signal, and its cycle can be such as 100ms, 200ms or 300ms etc., so not as limit.When CPU (central processing unit) 104 export sustainably there is the look-at-me ITR1 of predetermined period time, timing unit 102 can be made to stop timing.And when CPU (central processing unit) 104 operate abnormal or be between the starting period time; CPU (central processing unit) 104 cannot export the look-at-me ITR1 with predetermined period constantly; such as look-at-me ITR1 may become nonperiodic signal (such as becoming the signal being in low voltage level); also or the cycle change, and make timing unit 102 restart timing.When timing unit 102 timing reaches Preset Time, the voltage quasi position of the changeable reset signal RS1 of timing unit 102, to reset CPU (central processing unit) 104.Such as in Fig. 2 B embodiment, timing unit 102, when timing arrives Preset Time, transfers reset signal RS1 to low voltage level by high voltage level, to reset CPU (central processing unit) 104, then reset signal RS1 is returned to the state of high voltage level.If again there is the situation crashed in CPU (central processing unit) 104 between the starting period, and cause timing unit 102 timing to arrive Preset Time, timing unit 102 is in order to again to change the state of reset signal RS1, to reset CPU (central processing unit) 104, so repeatedly circulation timing Preset Time, reset CPU (central processing unit) 104, until CPU (central processing unit) 104 exports the look-at-me ITR1 with predetermined period sustainably.
It should be noted that the embodiment that the embodiment of above-mentioned look-at-me ITR1 and reset signal RS1 is only exemplary, not as limit in practical application.In other embodiments, look-at-me ITR1 can be also such as nonperiodic signal, and the preset state of look-at-me ITR1 can be such as specific voltage level.In addition, reset signal RS1 is not limited to when transferring low voltage level to yet and resets CPU (central processing unit) 104, such as, can change into according to side circuit design yet and reset CPU (central processing unit) 104 when transferring high voltage level to.
