Abstract
The invention discloses a kind of system for searching cable trace online using cloud computing, including characteristic signal generating means, cable signal reception device, cloud platform processing end, realize that target cable seeks footpath by changing voltage, the current angle value of target cable, and by cloud platform processing piecewise analysis.The present invention can realize cable locating footpath in the case where not disturbing power network normal operation, and will not be by Hz noise.
Description
Technical field
It is specifically a kind of to search cable trace online using cloud computing the present invention relates to cable locating footpath alignment system field
System.
Background technology
The a large amount of of power cable use the history for having had twenty or thirty year in China, use early stage the cable of operation present
ND, the situation that nobody knows are buried through entering path, therefore, when certain loop needs to have a power failure, it is difficult to find the disconnected of power failure
Road device, generally require to draw road to find, therefore it is very tight to find a kind of fast and effective power cable path orientation method
Force to make peace necessity.
The cable path-finding method that the country generally uses now adds the path-finding method of audio signal to have a power failure again.And there are many fortune
Row cable can not have a power failure, and how solve this contradiction as power system problem in the urgent need to address.American-European countries exists
The research sought in the positioning of footpath of power cable is more early, and the 70's of 20th century have just invented Electromagnetic coupling method and actinobolia, and
It is successfully applied in power cable positioning.Research of the China in terms of the positioning of cable locating footpath starts to walk very late, for electricity
The research of power cable trace localization method just starts in this 10 years, and by the effort of 10 years, the domestic technology in this field had
It is certain to improve, it is single due in this way, by the present situation of state's inner cable operation（Cable is intensive, and Hz noise is serious）Influence,
Therefore there is very big shortcoming in this scheme.
The content of the invention is it is an object of the invention to provide a kind of system for searching cable trace online using cloud computing, with solution
Certainly prior art cable locating footpath direction is not suitable for the problem of state's inner cable operation present situation.
In order to achieve the above object, the technical solution adopted in the present invention is：
The system for searching cable trace online using cloud computing, it is characterised in that：Including characteristic signal generating means, cable signal
Reception device, cloud platform processing end, the characteristic signal generating means send feature in one end of each cable to target cable
Electric signal, this feature electric signal change voltage, the angle of electric current in target cable, and the cable signal reception device is in each electricity
The other end of cable receives voltage, current signal in each cable, and voltage, current signal are sent into cloud platform processing end, cloud
Platform processes end is handled to obtain the angle value of voltage, electric current in each cable after receiving each voltage cable, current signal,
Judge that voltage, the cable of current angle change are target cable, that completes target cable seeks footpath.
The described system for searching cable trace online using cloud computing, it is characterised in that：The characteristic signal fills
Current Voltage phase shifting equipment is set to, by putting into electric capacity and inductance, the regular voltage x current for changing the circuit to the circuit
Angle.
The described system for searching cable trace online using cloud computing, it is characterised in that：The cable signal receives dress
Put the voltage x current angle change feature for by the open C T with puncture, directly gathering the circuit.
The present invention is led to by sending feature electric signal to target cable to change voltage in target cable, current angle
Cable signal reception device receiving voltage, current signal are crossed, voltage, electric current angle are obtained finally by the analysis of cloud platform processing end
The cable of change is spent, and judges it for target cable.Cable locating footpath can be realized in the case where not disturbing power network normal operation, and
And will not be by Hz noise.Acquisition terminal can be installed under not power-off condition, can using packaged type signal generation apparatus
With the power supply point and cable trace in easy-to-look-up any loop.
Brief description of the drawings
Fig. 1 is present system schematic diagram.
Embodiment
As shown in figure 1, search the system of cable trace online using cloud computing, including characteristic signal generating means, cable
Signal receiving device, cloud platform processing end, the characteristic signal generating means are sent in one end of each cable to target cable
Feature electric signal, this feature electric signal change voltage, the angle of electric current in target cable, and the cable signal reception device is each
The other end of individual cable receives voltage, current signal in each cable, and voltage, current signal are sent into cloud platform processing
End, cloud platform processing end are handled to obtain the angle of voltage, electric current in each cable after receiving each voltage cable, current signal
Angle value, judge that voltage, the cable of current angle change are target cable, that completes target cable seeks footpath.
Characteristic signal generating means is Current Voltage phase shifting equipment, regular by putting into electric capacity and inductance to the circuit
Change the circuit voltage x current angle.
Cable signal reception device is by the way that with the open C T punctured, the voltage x current angle change for directly gathering the circuit is special
Sign.
