Embodiment
Refer to Fig. 1, a kind of optical network unit long hair optical detection device 100 that it provides for embodiment of the present invention, whether described optical network unit long hair optical detection device 100 is normally luminous for detect optical network unit 200 at passive optical network.Described optical-fiber network checkout gear comprises that one starts identification module 110, detection module 140 and an abnormity early warning module 160.
Described startup identification module 110 is for identifying the different starting state of optical network unit 200.The different starting state of optical network unit 200 that starts identification module 110 identifications comprises three kinds, is respectively incomplete starting state, completely starts and do not plug optical fiber state and start the optical fiber state of having plugged completely.In present embodiment, when whether identification starts completely, whether the signal that the process that described startup identification module 110 receives last startup in optical network unit 200 booting scripts is sent is identified optical network unit 200 and has been started, when startup identification module 110 receives this signal, show to have started, when starting identification module 110, do not receive this signal, think and be not activated.
While whether plugging optical fiber after identification starts completely, start identification module 110 and receive the signal that last process sends, identifying optical network unit 200 has started, now by reading the state value of the reception input optical module pin PIN8 of optical network unit 200, judge whether optical network unit 200 has receipts light again, if there is no light signal, think not plug optical fiber, if there is light signal, thinks and plug optical fiber.The value of PIN8 is divided into low and high level, and high level indicates light signal, and low level indicates without light signal.
Described detection module 140 is for judging according to the different starting state of identified optical network unit 200 that respectively whether the luminance of obtained optical network unit 200 is normal.Detection module 140 comprises an acquiring unit 142, judging unit 144 and a comparing unit 146.
Described acquiring unit 142 its state values for the luminous indicating status value of optical network unit described in Real-time Obtaining 200 and the light emitting control configuration bit of described optical network unit 200 inside.The state value that described luminous indicating status value is optical module pin PIN20, when this value represents that optical network unit 200 is in luminance during for high level, when this value represents that optical network unit 200 is in luminance not during for low level.
Described judging unit 144 is starting state and when optical fiber state is not plugged in startup completely completely at the optical network unit 200 that starts identification module 110 identifications, when also starting identification module 110 and not receiving the signal that last process sends or the signal that receives last process and PIN8 and be low level, the luminous indicating status value of the optical network unit 200 obtaining according to acquiring unit 142 judge that whether optical network unit 200 is luminous normally.In present embodiment, optical network unit 200 in there is no complete start-up course and optical network unit 200 start while not plugging optical fiber completely, if the state value of the PIN20 that acquiring unit 142 obtains is high level, think that optical network unit 200 exists long hair optical phenomenon, close immediately optical network unit 200 luminous.If the state value of the PIN20 of acquiring unit 142 Real-time Obtainings is low level, illustrate that the normal and optical network unit 200 of optical network unit 200 luminances completes startup.Luminous and the state value of closing the PIN13 pin by optical network unit 200 of optical network unit 200 determines, when PIN13 pin is low level, optical network unit 200 is closed luminous, and when PIN13 pin is high level, optical network unit 200 is luminous.
Described comparing unit 146 at optical network unit 200 when starting completely and plugging optical fiber state, whether the luminous indicating status value of the optical network unit 200 that relatively acquiring unit 142 obtains is identical with the value of the light emitting control configuration bit of optical network unit 200 inside, if identical, illustrate that optical network unit 200 states are normal, if not identical, illustrate that optical network unit 200 occurs abnormal.The low and high level of the PIN13 of optical network unit 200 is determined according to the low and high level of light emitting control configuration bit, when the light emitting control configuration bit of optical network system inside is high level, the PIN13 that optical network unit 200 is set is high level, make optical network unit 200 luminous, when light emitting control configuration bit is low level, the PIN13 pin that optical network unit 200 is set is low level, closes the luminous of optical network unit 200.At comparing unit 146, relatively the value of PIN20 and the value of light emitting control configuration bit of optical network units 200 are identical and during for high level, expression optical network unit 200 is normally luminous.
Described abnormity early warning module 160 determines whether to carry out alarm according to the comparative result of the judged result of judging unit 144 and comparing unit.Abnormity early warning module 160 comprises an anomalous counts unit 162 and a setting unit 164.
When the value of PIN20 of optical network unit 200 is identical with the value of light emitting control configuration bit, anomalous counts unit 162 zero clearings simultaneously acquiring unit 142 restart to obtain the state value of the PIN20 of optical network unit 200, and the next round that also enters the PIN20 of optical network unit 200 detects.At the value of PIN20 of optical network unit 200 and the value comparative result of light emitting control configuration bit when not identical, illustrate optical network unit 200 luminous may occur abnormal, now anomalous counts unit 162 countings add 1, continue to read simultaneously and compare the PIN20 pin of optical network unit 200 and the state of light emitting control configuration bit, if there is once identical state in comparative result, 162 zero clearings of anomalous counts unit, the state value that acquiring unit 142 restarts to obtain the PIN20 of optical network unit 200 detects to reenter next round, if be in relatively unequal at least 3 times continuously ensuing, be that anomalous counts unit 162 countings are at least 4 times, now illustrate that long hair optical phenomenon appears in optical network unit 200.In present embodiment, close continuously optical network unit 200 at least 3 times when not identical luminous, be appreciated that continuously and relatively for not identical number of times, can set according to need.
Whether described setting unit 164 is luminous for controlling optical network unit 200 according to the count value of the judged result of judging unit 144 and anomalous counts unit 162.In present embodiment, setting unit 164 is that low level is luminous to close optical network unit 200 by controlling the value of pin PIN13.At optical network unit 200 complete starting state and start the optical fiber state of not plugging completely, when the state value of judging unit 144 judgement PIN20 is high level, the value that setting unit 164 is controlled PIN13 is low level optical network unit 200 is luminous carries out alarm to close.In present embodiment, be counted as in anomalous counts unit 162 at 4 o'clock, the value that setting unit 164 is controlled PIN13 is low level optical network unit 200 is luminous carries out alarm to close.
Be appreciated that, in order to there is long hair optical phenomenon in alerting light network element 200 better, abnormity early warning module 160 can also arrange hardware when the alarm of long hair optical phenomenon appears in optical fiber state and registers LED lamp as quick flashing state is to indicate this optical network unit 200 to have long hair light for starting to have plugged completely at optical network unit 200, and controls that optical network unit 200 is restarted so that optical network unit 200 returns to normally luminous.
