Description
Technical field
The utility model is related to line faults to indicate field, in particular to a kind of identical based on BlueTooth tri-
Walk the device for fault indicator of metrical information.
Background technology
In distribution network system, lines branch is more, and operating condition is complicated.When short circuit or earth fault occur for circuit, therefore
Barrier position is difficult to determine, brings no small difficulty, especially remote districts to service work, search and locate abort situation and more take
When it is laborious, and the appearance of line-failure indicator efficiently solves the above problem.Line-failure indicator is mounted on overhead line, electricity
In the power equipments such as power cable or case change, ring main unit, cable branch box, line is monitored by parameters such as the electric currents of detection circuit
The operating status on road.When line failure, determination abort situation that can be promptly and accurately is concurrently out of order warning message,
Line fault information can also be passed through the multiple communication modes such as GPRS, optical fiber, short message by the fault detector with communication function
Specified failed terminals are sent to, realize the teletransmission of fault-signal and the automatic positioning of abort situation, it is automatically fixed to constitute failure
Position system.
But the multiple communication modes such as GPRS, optical fiber, short message bring many inconvenient conditions at the scene in practical application,
First, to walk the dedicated public network of non-electricity, information security is difficult to ensure；Second is that rent public network for a long time is also to client
One no small investment；Third, the stability of wireless network, reliability cannot be guaranteed the accurate transmission of information.
Invention content
In order to solve the above technical problems, the utility model is intended to provide a kind of be based under BlueTooth wireless network modes
The device for fault indicator of synchro measure aerial cable three-phase current data, specific technical solution are as follows：
A kind of device for fault indicator based on BlueTooth three-phase synchronous metrical informations, including sampling module,
Bluetooth communication modules, Bluetooth communication modules are connected with sampling module, and sampling module is divided into a main sampling apparatus
With two points of sampling apparatuses, three sampling apparatuses acquire the information of threephase cable, sampling module continuous service respectively；
Bluetooth communication modules send synchronizing clock signals to sampling module, and main sampling apparatus is capped collected data absolute
Timestamp is simultaneously by Bluetooth communication modules to two points of harvester request datas；Further include memory, memory is used
Divide the data and the collected data of main sampling apparatus of harvester feedback in preservation；The memory is logical by Bluetooth
News module is connected with line feed terminals FTU devices.
Further, the sampling module persistently samples electric current with dma mode.
Further, the sampling module successively harvester power supply status, with line feed terminals FTU device communication states.
Technique effect：Compared with prior art, using the device for fault indicator technical solution of the utility model, Ke Yitong
Operation setting protection act logic is crossed, realizes the identification of faulty line.Open site BlueTooth wireless network work(simultaneously
Can, facilitate operation maintenance personnel's site operation and maintenance.

Fig. 3 is the operating status judgment formula schematic diagram of the utility model.
Specific implementation mode
Below in conjunction with the accompanying drawings, to the utility model is related to technical solution be described further.
Device for fault indicator based on BlueTooth three-phase synchronous metrical informations as shown in Figure 1, including sampling module
1, Bluetooth communication modules 2, Bluetooth communication modules 2 are connected with sampling module 1, and sampling module 1 divides to be adopted for a master
Sampling device 11 and two points of sampling apparatuses 12, three sampling apparatuses acquire the information of threephase cable respectively, and sampling module 1 is persistently transported
Row；Bluetooth communication modules 2 send synchronizing clock signals to sampling module 1, and main sampling apparatus 11 adds collected data
Lid absolute timestamp is simultaneously by Bluetooth communication modules 2 to two points of 12 request datas of harvester；It further include memory
3, memory 3 is used to preserve the data for dividing harvester to feed back and the collected data of main sampling apparatus；The memory 3 passes through
Bluetooth communication modules 2 are connected with line feed terminals FTU devices 4.
The sampling module 1 persistently samples electric current with dma mode, successively harvester power supply status and feeder line
Terminal FTU device communication states.
Collected data result carries out the judgement of operating status according to the formula expressed in Fig. 2, Fig. 3；After the completion of judgement,
Export corresponding fault diagnosis result.
It should be strongly noted that the above embodiment is to solve the preferred and not all technical solution of technical problem,
Being all based on the change of the technical program mentality of designing progress should all fall into protection domain.
