Abstract
The invention provides an optical fiber system power down detection notification method. Specifically, the method is the method of rapidly notifying an opposite side that equipment of the side is in a power down state and can not transmit normally when one of two ends of equipment in an optical fiber forwarding system is in the power down state and can not transmit normally.
Description
Technical field
The present invention is the detection of a kind of fibre system detection of power loss Notification Method, i.e. optical fiber repeater system wherein one end device looses power the method notifying counterpart device.
Background technology
Along with popularizing of network, the application limitation of twisted-pair wire net has had a strong impact on the scope of network topology, and the maturation along with optic fibre manufacture process, its cost reduces further, distance the most remote, middle all uses centralized optical fiber wire laying mode so that the application of fiber plant trends towards low cost, portability.
Generally in fiber-optic transfer there is larger distance in terminal device, occurs when the situations such as power down cannot be transmitted if which results in one end, and the other end can not be known immediately.The present invention the most successfully solves this problem, and i.e. after the situation of power down occurs in one end, the present invention can be immediately detected power-down conditions, and sends rapidly a frame state packet to far-end, informs the other side's local system power down, will be unable to normal transmission.
Summary of the invention
In a kind of fibre system detection of power loss Notification Method, i.e. optical fiber repeater system, one end device looses power detects and informs rapidly the method that counterpart device we's device looses power will be unable to normal transmission, and the method comprises the following steps:
Local device normal working voltage 2.5V, when power-down conditions occurs in equipment, when voltage drops to 2.1V, and local device voltage detecting circuit can detect this power down phenomenon；
After local device voltage detecting circuit detects power down phenomenon, provide control signal；
Local device sending function module sends a frame in the ensuing time rapidly and will be unable to the data of power down information of normal transmission with local device power down to distal fiber equipment, informs the other side's local device power down, will be unable to normal transmission.
Accompanying drawing explanation
In claims of present patent application, particularly point out subject of the present invention, and clearly it is proposed patent protection.But with reference to following detailed description and drawings, the relevant structure of the present invention and implementation method and its purpose, feature and advantage can be better understood from.
Fig. 1 fiber-optic transfer terminal device connection diagram；
Fig. 2 power supply power-fail process.
Detailed description of the invention
In the following detailed description, specific details is described to provide and the present invention being fully understood by.But professional and technical personnel is it will be recognized that the present invention can also implement by other similar details.
When equipment normally works, local device power supply occurs in that power-down conditions, power down process is as shown in Figure 2, when voltage is less than normal working voltage, and when reaching 2.1V, in local fiber system, voltage detecting circuit detects this power-down conditions, provide control signal, at this moment system can send power-down state Frame in an ensuing frame transmission, informs distal fiber equipment we's device looses power, will be unable to normal transmission.Below being i.e. embodiments of the present invention and process, fibre-optic transmission system (FOTS) two ends transmission equipment is as shown in Figure 1.
Although certain this feature describing the present invention described herein as and a kind of implementation method, but for persons skilled in the art, it will occur that many is revised, replaces, changed and equivalent substitution.Therefore, protection scope of the present invention by appended claim in the range of standard.
Claims (1)
1. in a fibre system detection of power loss Notification Method, i.e. optical fiber repeater system, one end device looses power detects and informs rapidly the method that counterpart device we's device looses power will be unable to normal transmission, and the method comprises the following steps:
Local device is in normal operating conditions, when power-down conditions occurs in equipment, when voltage drops to certain particular voltage level, and local device voltage detecting circuit can detect this power down phenomenon；
After local device voltage detecting circuit detects power down phenomenon, provide control signal；
Local device sending function module sends a frame in the ensuing time rapidly and will be unable to the data of power down information of normal transmission with local device power down to distal fiber equipment, informs the other side's local device power down, will be unable to normal transmission；
After distal fiber equipment receives power down notification information frame, status frames decoder with power down notification information is correctly decoded acquisition local device power down notification information, and providing marking signal, next distal fiber equipment master controller can control distal fiber equipment and realize no longer processing the local device operation such as Frame without response with local device communication or according to marking signal.
