Description
Technical field
The present invention relates to a kind of equipment remote status monitoring, particularly relate to a kind of fiber entering household type user terminal running status
Monitoring method.
Background technology
In cable television system HFC(hybred fiber-coax structure) in, the task of photoreceiver is to make an uproar with the additional of minimum
Sound and distortion, recover after fiber-optic transfer by the information entrained by light carrier, the therefore output characteristics concentrated expression of photoreceiver
The performance of whole cable television system.No matter various types of photoreceivers are all that to realize converting optical signals be radiofrequency signal
Equipment, thus meet the requirement of fiber-optic transfer.The effect of photoreceiver is exactly the detection faint optical signal through transmission, and puts
Greatly, regeneration former transmission signal.In cable television system, photoreceiver is indispensable important composition equipment.
Its key component has: its Main Function of (one) photodetector is to utilize photoelectric effect that optical signal is turned
Become the signal of telecommunication.In optical communication system, to the requirement of photodetector be highly sensitive, response is fast, noise is little, low cost and
Reliability is high.The ultimate principle of Photoelectric Detection process is that light absorbs.At present, conventional in optical communication system photoelectric detector
It is PIN photodiode and avalanche diode (APD).The Performance comparision of two kinds of detectors: due to PIN and APD of same performance
Comparing, the price of PIN is cheap, and the noise of PIN is low.(2) in signal processing space optical communication system, photoreceiver
The signal received is the faintest, the most in addition under the disturbed condition of high background noise field, can cause receiving terminal signal to noise ratio
S/N<1.So the process to signal is the most necessary.The measure being usually taken has: one is on optical channel, uses light narrow
Received optical signal is processed by band filter, to suppress the interference of background stray light.The fundamental type of optical filter has
Absorption filter, interference light filter, birefringent filter and novel atom resonance light filter etc..Two is in radio channel, adopts
The faint photogenerated current signal produced by photodetector with preamplifier is converted into voltage signal, then passes through main amplifier
Signal is amplified further.Then use the methods such as equilibrium and filtering that signal is processed.
The running status of photoreceiver equipment directly affects the radio TV signals receiving quality of terminal temperature difference, and photoreceiver is to light
The parameters such as fine input optical power, MER, BER, output level have strict threshold requirement, above parameter can by adjust decay and
Equilibrium value is adjusted, but fiber entering household type photoreceiver can only be wasted time and energy with regulation relevant parameter in field observation at present,
It is unfavorable for system maintenance.
Summary of the invention
It is an object of the invention to provide a kind of running status long-distance management maintenance method of fiber entering household type photoreceiver,
It includes remotely the identification of TV optical receiver running state information, the reading of registering one's residence, it is achieved by the TCMS net of TR069 message
Tube side sequence is remotely to the inquiry of the key parameters such as the output level of cable television light-receiving, input optical power, temperature and maintenance etc.
Function；It is easy to system remote safeguard.
The technical scheme is that
A kind of running status long-distance management maintenance method of fiber entering household type photoreceiver, it is characterized in that the method is led to
Cross newly-increased MIB node, through EPON network transfer management infomational message, it is achieved remote by the TCMS any known network management procedure of TR069 message
Thread management, for monitoring, inquire about and revise the output level of cable television light-receiving, input optical power and temperature parameter, to
The various states of upper parameter pass through network management system remote maintenance, it is simple to attendant's teleprocessing cable television photo-receiver is correlated with
Fault.
Above-mentioned newly-increased MIB node is defined as follows:
It is an advantage of the current invention that:
By newly-increased MIB node, through EPON network transfer management infomational message, it is achieved by the TCMS webmaster of TR069 message
Program remotely manages, for monitoring, inquiring about the key parameters such as the output level of cable television light-receiving, input optical power, temperature,
The various states of above key parameter are passed through network management system remote maintenance, it is simple to attendant's teleprocessing Cable TV Light connects
Receipts machine dependent failure.
Accompanying drawing explanation
Fig. 1 fiber entering household type photoreceiver fundamental diagram；
Fig. 2 fiber entering household type remotely located schematic diagram of photoreceiver key parameter.
Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is further described:
Fiber entering household type photoreceiver operation principle sees Fig. 1,
See Fig. 2, the invention discloses a kind of running status long-distance management maintenance method of fiber entering household type photoreceiver, pass through
Newly-increased photoreceiver equipment MIB node, by EPON network transfer management infomational message, it is achieved by any known network management procedure remotely to having
The functions such as the inquiry of key parameter, maintenance such as the output level of line TV light-receiving, input optical power, temperature, it is simple to system is remote
Journey is safeguarded.
Extension MIB is defined as follows:
In sum, the present invention is a kind of running status long-distance management maintenance method of fiber entering household type photoreceiver, by newly
Increase MIB node, for monitoring, inquire about and revise the output level of cable television light-receiving, input optical power, Temperature Key ginseng
The various states of above key parameter are passed through network management system remote maintenance, it is simple to attendant's teleprocessing cable television by number
Photoreceiver dependent failure.
Claims (2)
1. the running status long-distance management maintenance method of a fiber entering household type photoreceiver, it is characterised in that: the method is passed through
