Brief description of the drawings
Fig. 1 is the theory diagram of the device with polylith intelligent chip according to an embodiment of the invention.
Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Refer to Fig. 1.Device with polylith intelligent chip according to an embodiment of the invention includes polylith intelligent chip 1 and the one-to-one multiple watchdog circuit 2 of polylith intelligent chip 1 and reset monitoring module 3.
The input of each watchdog circuit 2 is electrically connected with the feeding-dog signal output end of corresponding intelligent chip 1, for receiving the feeding-dog signal that intelligent chip sends；The reset signal output end of each watchdog circuit 2 is electrically connected with the reset terminal of corresponding intelligent chip 1, and reset signal can be sent to intelligent chip 1 when watchdog circuit does not receive feeding-dog signal in Preset Time.The watchdog circuit of some devices also has function of voltage monitoring, when the voltage for monitoring device exceeds default voltage range, also can send reset signal to intelligent chip 1.
First signal input part of reset monitoring module 3 is electrically connected with the feeding-dog signal output end of polylith intelligent chip 1 respectively, reset terminal of the secondary signal input of reset monitoring module 3 respectively with polylith intelligent chip 1 is electrically connected, and the signal output part of reset monitoring module 3 is electrically connected with the alarm input of polylith intelligent chip respectively.Reset monitoring module 3 is used to carry out real-time monitoring to the situation of the reception reset signal of all intelligent chips 1 and transmission feeding-dog signal, monitoring that any one piece of intelligent chip 1 receive reset signal or in scheduled time t do not send feeding-dog signal, then judge that the intelligent chip goes wrong, and alarm signal is sent to other all intelligent chips communicated to connect with the intelligent chip for going wrong.Preferably, scheduled time t is 200ms~300ms.Each intelligent chip 1 is used to stop after alarm signal is received to send data to outside, occurs the situation of loss of data when intelligent chip resets so as to avoid.
Further, reset monitoring module 3 is used for when the intelligent chip for monitoring to go wrong sends feeding-dog signal, judge that the intelligent chip for going wrong recovers normal, and alarm release signals are sent to other all intelligent chips for recovering normal intelligent chip communication connection.Each intelligent chip is used to recover after alarm release signal is received to send data to outside.When (such as 3~5 minutes) do not release alarm signal for a long time, manual intervention can be applied for by intelligent chip 1 or reset monitoring module 3.
In a specific embodiment, be stored with intelligent chip connection relational table in reset monitoring module 3, and the intelligent chip connection relational table describes the communication connection relation of each intelligent chip and other intelligent chips in the device in the device with polylith intelligent chip.Reset monitoring module 3 is to find other all intelligent chips that the intelligent chip gone wrong with this is communicated to connect by inquiring about the intelligent chip connection relational table after judging that intelligent chip goes wrong.Correspondingly, reset monitoring module 3 is also to find other all intelligent chips communicated to connect with the normal intelligent chip of the recovery by inquiring about the intelligent chip connection relational table after judging that intelligent chip that this goes wrong recovers normal.Reset monitoring module 3 can select single-chip microcomputer.The alarm input of intelligent chip 1 is the interrupt signal input of the intelligent chip.
In the embodiment shown in fig. 1, the device that should have polylith intelligent chip is a data transmission equipment.The Main Function of data transmission equipment is, as base-station node, to be contacted with control system by optical fiber or Ethernet, and carrying out wireless data by the radio-frequency module of itself and terminal unit exchanges.The data transmission equipment includes four pieces of intelligent chips 1, and four pieces of intelligent chips 1 are separately contained among data transmission equipment main system module 100, base band control module 200, modulation /demodulation module 300 and radio-frequency module 400.Wherein, the intelligent chip in main system module 100 is ARM chips, runs Android system；Chip in base band control module 200 is also ARM chips, but without operating system；Intelligent chip in modulation /demodulation module 300 is dsp chip, does not have operating system；Intelligent chip in radio-frequency module 400 is ARM chips, does not have operating system；Having independent watchdog circuit 2 in each of the above module carries out reset operation.Reset monitoring module 3 employs the single-chip microcomputer of technical grade.
For each module two general purpose I/O lines monitoring feeding-dog signal and reset signals, general purpose I/O line connects the interrupting input of the intelligent chip of the module to reset monitoring module 3 in addition.For example, when the feeding-dog signal of the intelligent chip in modulation /demodulation module 300 disappears or reset signal occurs, reset monitoring module 3 can send alarm signal to the intelligent chip 1 in base band control module 200 and radio-frequency module 400, until the feeding-dog signal of the intelligent chip in modulation /demodulation module 300 occurs just releasing warning again；Again for example, when the feeding-dog signal of the intelligent chip in base band control module 200 disappears or reset signal occurs, reset monitoring module 3 can send alarm signal to the intelligent chip 1 in main system module 100, modulation /demodulation module 300.If feeding-dog signal does not occur for a long time in the intelligent chip in base band control module 200, reset monitoring module 3 can also send the signal for needing manual intervention to repair by the superior system of intelligent chip 1 in main system module 100.
Fig. 1 is only to be illustrated with data transmission equipment, it should be appreciated that the device with polylith intelligent chip of the invention can also other types of device or system.
The invention also discloses the reset monitoring method of the device with polylith intelligent chip, comprise the following steps：
The situation that all intelligent chips are received with reset signal and feeding-dog signal is sent carries out real-time monitoring；
If monitoring, any one piece of intelligent chip receives reset signal or does not send feeding-dog signal in scheduled time t, judges that the intelligent chip goes wrong, and sends alarm signal to other all intelligent chips communicated to connect with the intelligent chip for going wrong；
Other all intelligent chips communicated to connect with the intelligent chip for going wrong stop sending data to outside after the alarm signal is received.
Further, the reset monitoring method is further comprising the steps of：
After judging that intelligent chip goes wrong, if monitoring, the intelligent chip for going wrong sends feeding-dog signal, then judge that the intelligent chip for going wrong recovers normal, and alarm release signals are sent to other all intelligent chips for recovering normal intelligent chip communication connection；
Other all intelligent chips communicated to connect with the normal intelligent chip of recovery recover to send data to outside after alarm release signal is received.
Foregoing scheduled time t is 200ms~300ms.
Above description is to further illustrating that the present invention is done with reference to specific embodiment and accompanying drawing.But; the present invention obviously can be implemented in various other methods described different from this; those skilled in the art can be promoted according to actually used situation in the case of without prejudice to present invention, be deduced; therefore, the content of above-mentioned specific embodiment should not limit present invention determine that protection domain.
