Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Refer to Fig. 1, it is the internal information conveyer 100 in the packet network system of embodiment of the present invention, and the internal information conveyer 100 in described packet network system is for being sent to downstream unit 200 with packet mode by the message of packet network system.Conveyer 100 comprises a sending module 110, detection module 140 and a receiver module 120.The message whether every the above receiver module 120 of transmission logical path of described detection module 140 detections receives sending module 110 transmission is on time to determine whether alarm.
Sending module 110 is for periodically sending message information on every logical path, and the time that sending flow that arranging of period T allow according to system and fault detect needs is determined.In present embodiment, the unit that sends period T is millisecond or second.
Every part of message information that receiving element 122 sends from sending module 110, isolate corresponding logical path parameter, memory cell 124 comprises a plurality of memory blocks corresponding with the logical path parameter of described each message information, receiving element 122 by received message information according to corresponding logical path Parameter storage in the corresponding memory block of memory cell 124.
The interior default time threshold of described timing unit 142, in present embodiment, the size of time threshold be sending module 110 transmission period T N doubly, wherein, N is greater than or equal to 2 arbitrary value.In present embodiment, the size of time threshold is 3 times of transmission cycle.
Described judging unit 144 judges according to the interior default time threshold of timing unit 142 whether receiving element 122 has received message information in time threshold, if receiving element 122 has received the message information on counterlogic path, timing unit 142 zero clearings restart timing, if receiving element 122 does not receive message information after the timing of timing unit 142 exceeds time threshold, Alarm Unit 146 carries out alarm.
Described Alarm Unit 146 determines whether to carry out alarm operation according to the judged result of judging unit 144, and Alarm Unit 146 arranges alarm status flag bit and invalid code is stored to corresponding stored district when alarm.In present embodiment, Status Flag during Alarm Unit 146 alarm is set to " 1 ".Be appreciated that invalid code is according to actual needs setting, when downstream unit 200, can judge this information when memory cell 124 is obtained this invalid code is invalid code.
On every logical path, when receiving element 122 has received message information in the time threshold of timing unit 142, now receiving element 122 obtains the logical path parameter of this message information and this message information is stored in the memory block of memory cell 124 correspondences, if judging unit 144 judgement receiving elements 122 have received message information in time threshold, timing unit 142 need carry out zero clearing according to judged result, also at receiving element 122, receive each time after message information, timing unit 142 carries out zero clearing and starts reclocking.
After surpassing the timing time threshold value of timing unit 142, judging unit 144 judgement receiving elements 122 do not receive message information, Alarm Unit 146 carries out alarm, now rise as " 1 " the Status Flag position of Alarm Unit 146, invalid code is write in the memory block of corresponding memory cell 124 simultaneously, thereby make downstream unit 200 when gathering the information data in corresponding stored district, be checked through data invalid code, and abandon this invalid code and the fault message of Transfer pipe is transmitted backward simultaneously.
In present embodiment, in the internal information conveyer 100 in packet network system, adopt field programmable gate array (Field Programmable Gate Array, FPGA) technology to realize the function of receiver module 120 and detection module 140.
Refer to Fig. 2, the internal information transfer approach in its packet network system providing for embodiment of the present invention, described transfer approach is for being sent to downstream unit with packet mode by the message of packet network system, and described transfer approach comprises the following steps:
S100: periodically send message information on every logical path;
S200: from the message information receiving, isolate corresponding logical path parameter and by received message information according to corresponding logical path parameter corresponding stored;
S300: judge whether to have received message information in a default time threshold, if so, enter step S400; If not, enter step S500;
S400: timing zero clearing also restarts timing; And
S500: alarm corresponding stored invalid code.
In step S100, utilize sending module 110 on every logical path, periodically to send message information, the time that sending flow that arranging of period T allow according to system and fault detect needs is determined.In present embodiment, the unit that sends period T is millisecond or second.
In step S200, if receiving element 122 has received message information, receiving element 122 obtains the logical path parameter of this message information and this message information is stored in the memory block of memory cell 124 correspondences.
In step S300, judging unit 144 judges whether receiving element 122 has received message information, and if so, timing unit 142 carries out zero clearing and starts reclocking after receiving element 122 receives message information each time, if not, Alarm Unit 146 carries out alarming processing.
In step S400, the judged result that timing unit 142 has received message information according to judging unit 144 judgement receiving elements 122 will start reclocking state behind institute's timing Changqing zero.After the duration that timing unit 142 to time threshold sets if be appreciated that, receiving element 122 does not receive a message information, and now timing unit 142 is timeout mode, thereby judging unit can be controlled Alarm Unit 146 and carries out alarm.
In step S500, rise as " 1 " Status Flag position during Alarm Unit 146 alarm, invalid code is write in the memory block of corresponding memory cell 124 simultaneously.
In present embodiment, in the internal information conveyer 100 in packet network system, adopt field programmable gate array (Field Programmable Gate Array, FPGA) technology to realize the function of receiver module 120 and detection module 140.
Internal information conveyer and transfer approach in packet network system provided by the invention, adopt timing unit 142 to judge according to default time threshold whether receiving element 122 receives in time message information and whether break down with timely perception Transfer pipe in time threshold, and utilize Alarm Unit 146 to do corresponding alarming processing according to the fault occurring, thereby avoid transmitting false wrong information, guarantee to provide information promptly and accurately to downstream unit 200.
Be understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion by technical conceive according to the present invention, and all these change and distortion all should belong to the protection range of the claims in the present invention.
