Description
Technical field
The utility model relates to a kind of digital magnetic flux cable tension sensor, belongs to magnetic flux detecting sensor technical field.
Background technology
Magnetic flux transducer is that the magnetoelastic effect principle based on ferrimagnet is made.In the time that external world's machinery load that ferrimagnet bears changes, its inner magnetization (magnetic permeability) changes, and the magnetic permeability of the member of making by measurement ferrimagnet changes, and measures the internal force of member.Can effectively measure the stress of cable and presstressed reinforcing steel, be a kind of emerging Dynamic Non-Destruction Measurement.
Known magnetic flux amount cable tension sensor, the induced voltage that inductive coil obtains, passes to vasculum by cable.In vasculum, be converted to the magnitude of voltage of induction by A/D.
Known magnetic flux amount cable tension sensor is all simulated, and it receives induction simulating signal inductive coil, directly gives data acquisition instrument.Because induction simulating signal is easily interfered, the conductor length between data acquisition device and sensor are straight has certain restriction, has restricted the application of sensor.
Summary of the invention
In order to overcome above-mentioned defect, the purpose of this utility model is to provide a kind of digital magnetic flux cable tension sensor, and this sensor, by the induced signal that inductive coil is obtained, converts digital signal to, has avoided like this induced signal distortion in the process of transmission.Thereby the precision and the transmission range that gather are improved.
To achieve these goals, the utility model adopts following technical scheme:
A kind of digital magnetic flux cable tension sensor, is connected by cable between vasculum and magnetic flux transducer, places test cable in the middle of magnetic flux transducer;
It comprises drive coil, inductive coil, circuit board described magnetic flux transducer, between described inductive coil and circuit board, is connected by connecting line I; Between described drive coil and circuit board, be connected by connecting line II.
Vasculum, by cable, is connected on the circuit board of sensor, provides pumping signal respectively to circuit board, and circuit board power supply, and CAN bus communication signal.Pumping signal to drive coil, produces magnetic field by connecting line II on cable, and inductive coil obtains the induced voltage that cable changes of magnetic field produces, and changes CAN bus signals by connecting line I after to circuit board; CAN bus signals is pulled and is returned to vasculum by line again.
It includes A/D conversion chip, single-chip microcomputer, level transferring chip described circuit board;
Induced signal is converted to digital signal through A/D conversion chip induced voltage, read again the numerical value of induced voltage by single-chip microcomputer, single-chip microcomputer sends digital signal, is converted to CAN bus signals by level transferring chip, and CAN bus is carried out communication by cable and vasculum.
The beneficial effects of the utility model:
The utility model has been avoided the interference of outer bound pair induced signal after processing by induced voltage is quantized, and has improved Product Precision.Reduced sensor to the required distance between Acquisition Instrument simultaneously.The range of application of magnetic flux cable tension sensor is expanded.
