Abstract
The utility model discloses the device of the seamless cutover of a kind of dispatched users, comprise old switch (2); The port of described old switch (2) is connected with the terminal of PCM equipment (5) side by tone frequency channel wire I (6); Described tone frequency channel wire I (6) is provided with safety unit I (1) with the junction of old switch (2) port; It is characterized in that the opposite side terminal of described PCM equipment (5) is connected with the port of new switch (4) by tone frequency channel wire II (7); The port of described new switch (4) and the junction of tone frequency channel wire II (7) are provided with Security Unit II (3); Described PCM equipment (5) constitutes old switch number (8) and new switch number (9) respectively with the connection of old switch (2) and new switch (4).The utility model is by voice distribution frame and connect, the pattern changed by Security Unit, realizes the seamless cutover of dispatched users.Do not affect any call of dispatched users, ensure the accuracy of the unimpeded and cutover of the commander of whole electrical network.Solve prior art to exist when changing switch and need power-off, affect the technical problem of normal consistency.
Description
Technical field
The utility model belongs to scheduling switch voice frequency distributing fixture technology field, relates to the device of the seamless cutover of a kind of dispatched users.
Background technology
Dispatching telephone is commander's passage of power scheduling, and the whether unimpeded order command directly having influence on whole electrical network is assigned.During company's scheduling switch succession of the old by the new, just relate to the cutover work of dispatched users, need dispatched users to be switched to new switch from the port of original switch.Time conventional cutover is generally arranged in that evening, traffic carrying capacity was little, carry out stoppage in transit cutover.First Security Unit is pulled up, line of dismantling, remove former switch ports themselves line, be changed to new switch ports themselves line, then according to new switch distribution data, number is skipped to transformer station, realize the cutover of the old and new's switch.The process of cutover is exactly the process that dispatched users is interrupted, and during this, power scheduling command centre cannot contact dispatched users, and prior art cutover break period is 2-6 hour.Due to the particularity of dispatched users, not only need daytime to ensure that phone is unimpeded, and each power plant also needs to report electricity etc. evening, part is directly under the provincial Party committee in addition simultaneously calls family, therefore whole day all likely has emergency or accident in 24 hours, and stoppage in transit cutover will inevitably affect the normal use of dispatched users.
Summary of the invention
The purpose of this utility model needs power-off to solve when prior art exists and changes switch, affect the technical problem of normal consistency, and provide the device of the seamless cutover of a kind of dispatched users, this device completes cutover when guarantee phone is unimpeded.
To achieve these goals, the device of cutover that a kind of dispatched users of the utility model is seamless, it comprises old switch; The port of described old switch is connected with the terminal of PCM equipment side by tone frequency channel wire I; Described tone frequency channel wire I is provided with safety unit I with the junction of old switch ports themselves; Its main points are that the opposite side terminal of described PCM equipment is connected by the port of tone frequency channel wire II with new switch; The port of described new switch and the junction of tone frequency channel wire II are provided with Security Unit II; The connection of described PCM equipment and old switch and new switch constitutes old switch number and new switch number respectively.
Concrete operation method is as follows: to be connect by voice distribution frame, the pattern changed by Security Unit, realize the seamless cutover of dispatched users, for the distribution between old switch ports themselves and each transformer station PCM access device, new switch ports themselves is connected in the module of band Security Unit in addition, and by the other side of new switch ports themselves number corresponding jumper connection to PCM terminal, realize at PCM equipment side and connect.
The utility model achieves the seamless cutover of dispatched users, reliable communication support is provided for whole dispatching of power netwoks commander is unimpeded, in addition, after all business are transformed into new switch, former switch wire jumper still retains, can for subsequent use as new switch, if new switch initial operating stage has any problem, by the conversion of Security Unit, dispatched users can be switched back old switch instantaneously, prevent new switch fluctuation of service, fully ensure that the reliability of dispatching telephone.The utility model is by voice distribution frame and connect, the pattern changed by Security Unit, realizes the seamless cutover of dispatched users.Do not affect any call of dispatched users, ensure the accuracy of the unimpeded and cutover of the commander of whole electrical network.
The utility model cutover mode not only may be used for the seamless cutover of dispatched users, also may be used for administrative user, and the cutover of communication outside line side can be extended to, change former communication cutover flow process, accomplish not interrupt communication business, greatly ensure that the reliability service of communication user.

Embodiment
With reference to accompanying drawing, the utility model comprises old switch 2; The port of described old switch 2 is connected with the terminal of PCM equipment 5 side by tone frequency channel wire I 6; Described tone frequency channel wire I 6 is provided with safety unit I 1 with the junction of old switch 2 port; The opposite side terminal of described PCM equipment 5 is connected with the port of new switch 4 by tone frequency channel wire II 7; The port of described new switch 4 and the junction of tone frequency channel wire II 7 are provided with Security Unit II 3; Described PCM equipment 5 constitutes old switch number 8 and new switch number 9 respectively with the connection of old switch 2 and new switch 4.
Its method of operation is as follows: connect, the pattern changed by Security Unit by tone frequency channel wire, realize the seamless cutover of dispatched users; Detailed distribution data is arranged between old switch ports themselves and each transformer station PCM access device, new switch ports themselves line is connected in the module of band Security Unit in addition, according to the distribution data arranged, by the other side of new switch ports themselves number corresponding jumper connection to PCM terminal, realize in PCM terminal equipment side and connect.
Now, each dispatched users can have two pairs of audio frequency wire jumpers simultaneously, is connected to old switch for a pair, is connected to new switch for a pair.
Only have connection Security Unit, dispatching telephone is only connection, therefore, and that transformer station's dispatched users is connected or original scheduling switch; When all dispatched users all complete the old and new's two switches port and after connecing, when confirming that dispatched users is untapped one by one, pull up the Security Unit of old switch ports themselves, connect the Security Unit of new switch ports themselves, dispatched users just achieves the moment cutover work being switched to new switch by old switch simultaneously; Due to this moment dispatched users do not use, any call of dispatched users can not be affected, be therefore called seamless cutover.
The utility model cutover is operated in dispatched users and completes without moment of business, does not affect any call of dispatched users, ensure that the commander of whole electrical network is unimpeded, and all connections is fulfiled ahead of schedule, and test errorless, ensures cutover accuracy; The utility model realizes the seamless cutover of dispatched users, reliable communication support is provided for whole dispatching of power netwoks commander is unimpeded, in addition, after all business are transformed into new switch, old switch wire jumper still retains, can for subsequent use as new switch, if new switch initial operating stage has any problem, by the conversion of Security Unit, dispatched users can be switched back old switch instantaneously, prevent new switch fluctuation of service, fully ensure that the reliability of dispatching telephone.
