Wherein image intensifer is through shoveller's operation mode moderator; A ytterbium-erbium is mixed multimode cladding pumping high-power fiber amplifier equipment altogether and is set to main equipment in advance; Another is set to slave unit; Communicate through moderator between master-slave equipment, main equipment is responsible for gathering relevant information, and arbitrates which platform equipment entering operating state.Main equipment work under the normal condition, and through 1 * N optical splitter output light signal, and, realize the light signal output of 2N road through the further beam split of 2 * 2 * N spectral array.Do not work or main equipment is imported when undesired when main equipment, main equipment gets into operating state through main road moderator notice slave unit.Like this, former main equipment is no longer exported light signal, through 1 * N optical splitter output light signal, still is divided into the light signal output of 2N road through shared 2 * 2 * N spectral array by slave unit.
The redundant spectral array of 2 * 2 * N is made up of N 2 * 2 optical splitters, is pure inactive component, and input connects main road respectively and exports from the optical splitter on road, no matter be main equipment work or slave unit work like this, its output all has light signal.Thereby realized the redundancy backup function of output.
1 * N optical splitter realizes that the shunt of high-power output light signal is handled, and the output light signal of equipment is reduced to can carries out conventional attended operation, and prepare for the redundant output of the multichannel of next stage.
Primary arbitrator or main equipment are served as the task of the operating state of real-time monitoring master-slave equipment, and after main equipment was in proper working order, initial operating state can automatically switch back.
Fig. 2 is the equipment connecting relation sketch map that scheme 2 of the present invention adopts.Technical scheme 1 of the present invention comprises following equipment: ytterbium-erbium that main frame/slave can be set is mixed 2 of multimode cladding pumping high-power fiber amplifier equipment, mode of operation moderator 2 covers and 2 * N optical splitter, 1 cover altogether.
This programme is mainly mixed multimode cladding pumping high-power fiber amplifier equipment by 2 ytterbium-erbiums that principal and subordinate's mode of operation can be set altogether, wherein every cluster tool 1 cover mode of operation moderator, 1 cover, 2 * N optical splitter is realized.Wherein image intensifer is through shoveller's operation mode moderator; A ytterbium-erbium is mixed multimode cladding pumping high-power fiber amplifier equipment altogether and is set to main equipment in advance; Another is set to slave unit; Communicate through moderator between master-slave equipment, main equipment is responsible for gathering relevant information, and arbitrates which platform equipment entering operating state.Main equipment work under the normal condition, output light signal realize the light signal output of N road through the beam split of 2 * N optical splitter.Do not work or main equipment is imported when undesired when main equipment, main equipment gets into operating state through main road moderator notice slave unit.Like this, former main equipment is no longer exported light signal, by slave unit output light signal, still is divided into the light signal output of N road through shared 2 * N optical splitter.
2 * N optical splitter is 2 inputs, and the pure inactive component of N output, input connect main road respectively and from the output of the optical amplifier arrangement on road, no matter be main equipment work or slave unit work like this, its output all has light signal.Thereby realized the redundancy backup function of output.
Primary arbitrator or main equipment are served as the task of the operating state of real-time monitoring master-slave equipment, and after main equipment was in proper working order, initial operating state can automatically switch back.
Fig. 3 is the workflow sketch map of primary arbitrator of the present invention.As shown in Figure 3: the course of work of primary arbitrator is following: (1) start; (2) be set to host mode; (3) whether inspection work at present state is normal, if normally then keep current working state constant; If undesired, then notify slave to get into mode of operation, main frame gets into standby mode.
Fig. 4 is the workflow sketch map from moderator of the present invention.As shown in Figure 4: following: (1) start from the course of work of moderator; (2) be set to slave mode; (3) wait for Host Command,,, then get into standby mode if the order of receiving is shutdown if the order of receiving is to start shooting then get into mode of operation.
The odds of scheme of the present invention 1 and scheme 2 is:
Scheme 1: in practical application, be easy to fitting operation.Because integrated 1 * N optical splitter can make the Output optical power of each output port on the equipment be lower than 300mW in every high power amplifier equipment, so just can adopt the wire jumper mode of routine to carry out the connection of output light path.Therefore use installation fairly simple.But optical splitter and tie point required in the output light path are more, the output light path relative complex some.
Scheme 2: it is fairly simple to use light path, and required optical splitter and tie point are minimum.But because directly the luminous power from the output of high power multiplying arrangement is very high, can not adopts conventional wire jumper mode to be connected with optical splitter, and must adopt on-the-spot fusing mode to carry out the connection of output light path, installation difficulty is bigger during use.
Ytterbium-erbium of the present invention is mixed the thinking that multimode cladding pumping high-power fiber amplifier heat backup method adopts innovation altogether; Changed the method for designing that the traditional optical backup adopts optical switch to switch; A thereby difficult problem of having avoided the light path mechanical type under the output high power light signal condition to switch; Adopt the notion of master/slave arrangement; Mix multimode cladding pumping high-power fiber amplifier equipment to the same ytterbium-erbium of 2 covers altogether through the mode of operation moderator and be set at main equipment and slave unit respectively, and can realize the automatic conversion of master-slave equipment operating state according to the operating state of reality.Full optical fiber passive optical splitter in conjunction with high reliability is used, and has solved ytterbium-erbium well and has mixed the difficult problem of multimode cladding pumping high-power fiber amplifier equipment because of the too high difficult backup of output luminous power altogether, has promoted the reliability and the useful life of whole system greatly.
The present invention is in line with the requirement that improves system reliability, and the master/slave image intensifer of 2 covers, master/slave moderator used among the present invention are same equipment, just through its working method of software setting; Reduced the kind of equipment; Improved reliability, remaining optical splitter etc. are inactive component; Its failure rate is significantly less than active equipment, and more than design can improve the global reliability of system greatly.
The present invention adopts this backup method, both can realize redundancy backup function required when high-power fiber amplifier itself breaks down, and also can realize redundancy backup function required when front end output equipment or link occurs fault.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention, and under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications; These variations and improvement all fall in the scope of the invention that requires protection, and the present invention requires protection range to be defined by appending claims and equivalent thereof.
