Description
Technical field
The utility model relates to the special flexible T unit of a kind of power industry, particularly relates to a kind of special flexible T unit covered without public network signal.
Background technology
Realize in the process of construction of all standing, full collection, control in full in acquiring electric energy information system, part specially becomes user because being in basement or remote mountain areas, the public network signals such as movement, UNICOM do not cover, special change negative control terminal cannot with collection master station communication, for this reason current solution mainly contains following several:
1. adopt wire signal extender, see Fig. 1.
By independent for the communication module of acquisition terminal, be arranged on the place that public network signal covers, communication module and terminal pass through wired connection.
Advantage: all business specially becoming acquisition terminal can be realized, comprise check meter, power purchase, ordered electric etc.
Shortcoming: need to lay longer order wire, often need rice up to a hundred, quantities is large, and some environment cannot lay order wire.
If cover without public network signal, as the mining plants of remote mountain areas, then the method cannot be adopted around.
2. adopt concentrator+collector mode, see Fig. 2.
For only checking meter, without the need to the special change user of power purchase, concentrator is adopted to add the mode of collector, as Fig. 2:
Summary table and low-pressure meter access collector by 485 lines, and collector is converted to carrier wave, by the concentrator of 220V power line transmission to ground, is sent to main website through GPRS.
Advantage: quantities is few, solves the copy reading problem of high pressure gauge across transformer.
Shortcoming: concentrator takes control function without locality, cannot implement the service control such as power purchase, ordered electric.If cover without public network signal, as remote mountain areas, then the method cannot be adopted around.
3. reload signal amplifier, is shown in Fig. 3.
When no signal in power distribution room, and near when having a signal, can reload signal amplifier, neighbouring signal is introduced power distribution room by feeder line and amplifies.
Networking mode
Advantage: construction is simple, and equipment investment is few, can solve the problem of checking meter.
Shortcoming: the business such as power purchase, spatial load forecasting cannot be carried out.Because the working power of amplifier is generally given altogether by user, when the tripping operation of user's electricity deficiency, the whole 220V low pressure dead electricity of user, amplifier is also by dead electricity, and public network signal interrupts, and main website cannot descend generated energy to arrive terminal, therefore, the business such as power purchase, control can not be implemented.
Public network signal must be there is near user's power distribution room.
Above-mentioned several mode all can not solve no signal well and cover the long-range power purchase business that the special all business becoming acquisition terminal of special transformer terminals uplink communication problem realization especially specially become user.Utility model content.
It is simple that the purpose of this utility model is to provide a kind of construction, can complete the special flexible T unit covered without public network signal specially becoming all business of acquisition terminal.
This special flexible T unit covered without public network signal that the utility model provides, there is a near-end and a far-end, near-end and special transformer terminals are installed nearby, near-end is primarily of the first main control unit, first high-speed digital transmission radio station and RJ45 Ethernet data access unit composition, a described RJ45 Ethernet data access unit is connected by the first main control unit with between the first high-speed digital transmission radio station, proximally by a RJ45 interface and special transformer terminals interaction data, and the 230MHz wireless channel of special transformer terminals upstream data by the first high-speed digital transmission radio station is forwarded, far-end is arranged on the place of GPRS quorum sensing inhibitor, far-end is primarily of the second main control unit, the second high-speed digital transmission radio station, GPRS module composition, be connected by the second main control unit between GPRS module with the second high-speed digital transmission radio station, the 230MHz wireless channel in the second high-speed digital transmission radio station is forwarded to GPRS module through the second main control unit, by GPRS channel transfer to main website after receiving the data that near-end sends.
Described first high-speed digital transmission radio station and the second high-speed digital transmission radio station running parameter are: communication frequency is 230MHz, traffic rate is 19200bps.
For avoiding this specially to become the situation of user because of far-end dead electricity after control tripping operation, described near-end and specially change acquisition terminal adopt this special variable power source, and described far-end adopts public variable power source or other special variable power sources.
The utility model is owing to adopting 230M radio communication between near-end and far-end, can penetrate multilayer floor slab, repeater span is far away, in the unobstructed situation in ground, distance between near-end and far-end can at a distance of 10km, as long as there is public network signal to cover (within 10km) on a large scale, all can completes communication, both adapt to basement power distribution room user, adapt to remote mountain areas user again, construction is simple, and engineering cost is few, can complete and specially become all business such as the checking meter of user, power purchase, ordered electric.
