Technical field
The utility model relates to detection range, relates in particular to a kind of long-range water power for online detection foamed coaxial cable capacitance and holds pick-up unit.
Background technology
The online water power appearance detecting instrument of foamed coaxial cable mainly is to connect by the cable data transmission mode at present, data are transferred to display device by communication cable, therefore just exist the communication cable of wired connection complexity, cost height, connection usefulness to be subjected to the shortcomings such as interference of motor device on every side easily.Simultaneously present water power holds main outer the power supply of detecting instrument, because the existence of outer power voltage fluctuation, can have bigger influence to the correctness of capacitance measurements.
The utility model content
Technical problem to be solved in the utility model provides a kind ofly to be convenient to detect and long-range water power that accuracy of detection is high holds pick-up unit.For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of long-range water power holds pick-up unit, comprise the detection sleeve, be provided with the flowing water cavity that a sealed volume and front and back connect in the described detection sleeve, sealing is provided with two electrodes, a current detection circuit, a control chip, a battery and a radio receiving transmitting module in the described sealed volume, described electrode is connected with control chip by current detection circuit, described control chip is connected with a computing machine by radio receiving transmitting module, and described battery is connected with current detection circuit; Described electrode is fixed on the inwall that detects sleeve.
Further, described detection sleeve outer wall is provided with a USB charging connector, and described control chip, battery all are connected with the USB charging connector.
Preferably, described electrode is to paste to be connected with detecting sleeve.
The long-range water power that the utility model relates to holds pick-up unit and adopts wireless communication mode, can install, be placed on any position arbitrarily, it can directly be transferred to detected capacitance on the remote computer by radio receiving transmitting module in any position, computing machine can the real-time storage concentric cable capacitance, and need not the independent display interface of installing, directly just can show the capacitance of collection by far-end computer, and can carry out follow-up data analysis by computing machine.Testing circuit adopts powered battery simultaneously, and the measuring result error of having avoided other external dc power voltage fluctuations to cause makes measurement result more accurate.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is fundamental diagram of the present utility model.
Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
See Fig. 1 and Fig. 2, a kind of long-range water power that the utility model relates to holds pick-up unit, comprise and detect sleeve 1, be provided with the flowing water cavity 12 that a sealed volume 11 and front and back connect in the described detection sleeve 1, sealing is provided with two electrodes 2, a current detection circuit 3, a control chip 4, a battery 5 and a radio receiving transmitting module 6 in the described sealed volume 11, described electrode 2 is connected with control chip 4 by current detection circuit 3, described control chip 4 is connected with a computing machine 7 by radio receiving transmitting module 6, and described battery 5 is connected with current detection circuit 3; Described electrode 2 is fixed on the inwall that detects sleeve 1.
Form capacitance electrode between two electrodes 2, tested concentric cable 9 is placed in the flowing water cavity 12, and the aqueous medium circulation is arranged in the flowing water cavity 12.During measurement, tested concentric cable 9 is by flowing water cavity 12, at this moment, just from having only aqueous medium to become the medium of power and water cable mixing is arranged between two electrodes 2, variation has also just taken place in the electric capacity between such two electrodes 2, therefore current detection circuit 3 just can detect capacitance variations and the electric current that produces changes, thereby converses the capacitance of cable by the current value that changes, and capacitance is transferred to control chip 4; Described control chip 4 sends to far-end computer 7 enterprising line data analysis and demonstrations with the capacitance of cable by radio receiving transmitting module 6 again.In the present embodiment, what described radio receiving transmitting module 6 sent is the ISM band 868MHZ wireless signal of standard, and this wireless signal distance sensing is far away, is not subject to disturb, and signal is strong to the barrier penetration capacity.
Further, described detection sleeve outer wall is provided with a USB charging connector 8, described control chip 4, battery 5 all are connected with USB charging connector 8, so that the battery 5 of current detection circuit 3 is charged and regularly control chip 4 carried out program down loading updating.
Preferably, described electrode 2 is to paste to be connected with detecting sleeve 1.
The long-range water power that the utility model relates to holds pick-up unit and adopts wireless communication mode, can install, be placed on any position arbitrarily, it can directly be transferred to detected capacitance on the remote computer by radio receiving transmitting module in any position, computing machine can the real-time storage concentric cable capacitance, and need not the independent display interface of installing, directly just can show the capacitance of collection by far-end computer, and can carry out follow-up data analysis by computing machine.Testing circuit adopts powered battery simultaneously, and the measuring result error of having avoided other external dc power voltage fluctuations to cause makes measurement result more accurate.
