Wherein, webmaster submodule 411 is used for and extraneous control appliance, and (PC) carries out information interaction as personal computer.And other submodule except that webmaster submodule 411 and FPGA submodule 46, its connected mode and function are similar substantially with the connected mode and the function of corresponding submodule shown in Figure 3, and just signal flow is to changing to some extent.Such as, in Fig. 3, input video conversion submodule 34 and data submodule 310 etc. are that the signals such as video, audio frequency or data that will receive are exported to FPGA submodule 36, so that FPGA submodule 36 carries out chnnel coding; And in Fig. 4, be by FPGA submodule 46 signals such as video, audio frequency or data that obtain behind the channel-decoding to be exported to output video conversion submodule 44 and data submodule 410 etc.
And as shown in Figure 4, optical transceiver center-side module 22 described in the utility model is further to have increased cache sub-module 461 and definite submodule 462 with the main distinction of prior art in FPGA submodule 46.That is to say that the function of cache sub-module 461 and definite submodule 462 all can be realized by the FPGA submodule.Cache sub-module 461 receptions and buffer memory are from the magnitude of voltage and the temperature value of optical transceiver remote end module 21; When the communication disruption between optical transceiver center-side module 22 and the optical transceiver remote end module 21, determine the reason that submodule 462 can determine to take place transmission fault according to the temperature value and the magnitude of voltage of the optical transceiver remote end module 21 of buffer memory in the cache sub-module 461.
Need to prove, adopt the FPGA field programmable gate array in the utility model, utilizing hardware description language that FPGA is carried out hardware logic by module/submodule logical construction in the novel described scheme of this reality and logical relation thereof describes, and, placement-and-routing comprehensive by the FPGA tool software, logical resource with FPGA inside, associate as gate circuits such as look-up table, random asccess memory (RAM) piece, d type flip flop and NAND gate, realize desired function.
In addition, in actual applications, for optical transceiver remote end module 21, can there be a charge threshold level and a temperature threshold value, if current magnitude of voltage is less than this charge threshold level, and/or current temperature value is higher than this temperature threshold value, and then optical transceiver remote end module 21 is cisco unity malfunction, so cause and optical transceiver center-side module 22 between communication disruption.So, also can further comprise an alarm submodule 463 in the FPGA submodule 46 shown in Figure 4, this alarm submodule 463 is connected with cache sub-module 461, and pass through this connection and monitor the also magnitude of voltage of buffer memory of cache sub-module 461 receptions, and the temperature value of monitoring cache sub-module 461 receptions and buffer memory by this connection, when described magnitude of voltage reaches predefined first threshold value (being charge threshold level) or described temperature value and reaches predefined second threshold value (being temperature threshold value), alarm submodule 463 will be alarmed, and note to remind operating personnel.Usually, first threshold value is meant that 80%, the second threshold value of optical transceiver remote end module 21 operate as normal required voltage values is meant 70 degree.
Above-mentioned cache sub-module 461, determine that submodule 462 and alarm submodule 463 promptly form the reception judge module of being mentioned before.
Follow-up, when communicating by letter between optical transceiver remote end module 21 and the optical transceiver center-side module 22 interrupted, in the time of need carrying out the transmission fault analysis of causes, this is constantly when determining that submodule 462 can utilize magnitude of voltage in the optical transceiver remote end module 21 or temperature value to reach threshold value, cache sub-module 461 receives the also magnitude of voltage and the temperature value of buffer memory, and should receive the also magnitude of voltage and the temperature value of buffer memory constantly afterwards, determine to occur the reason of transmission fault.As described above, temperature value is unusual if magnitude of voltage is normal, then can determine the former because optical transceiver remote end module 21 of transmission fault because temperature is too high cisco unity malfunction; Magnitude of voltage is unusual if temperature value is normal, can determine that then former the because power supply of optical transceiver remote end module 21 of transmission fault breaks down; If temperature value and magnitude of voltage are all normal, can determine that then former because optical transceiver remote end module 21 of transmission fault and optical fiber between the optical transceiver center-side module 22 go wrong, as interruption etc.
Need to prove, in actual applications, cache sub-module 461, determine submodule 462 and the alarm submodule 463 also can be provided with separately, be not to be arranged in FPGA submodule 46, shown in Figure 4 only for illustrating.
Further, determine that submodule 462 also can further be connected with the indicator light that sets in advance (not shown), like this, determine that submodule 462 can send the transmission fault reason of determining to indicator light by this connection, so that indicator light indicates the transmission fault reason to operating personnel.Such as, can set in advance two indicator light A and B, if it is too high to determine the former because temperature of transmission fault, continuous flashing indicator light A then; Break down if determine the former because power supply of transmission fault, then continuous flashing indicator light B; If it is former in fiber break to determine transmission fault, arbitrary indicator light does not then glimmer.Like this, operating personnel can be known the current reason that transmission fault occurs by the state of viewing lamp, and then make corresponding processing.Perhaps, cache sub-module 461 also can directly be exported to PC with the information of buffer memory, by PC the information that receives is shown to operating personnel, is gone to carry out the analysis of transmission fault reason artificially by operating personnel.
In a word, adopt scheme described in the utility model, can when the communication between optical transceiver remote end module and the optical transceiver center-side module takes place to interrupt, in time determine the reason that transmission fault takes place, thereby be convenient to safeguard.
In sum, more than be preferred embodiment of the present utility model only, be not to be used to limit protection range of the present utility model.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
