7. Sensor introduction
Magnetic sensor: The sensor is composed by displacement locator (Leading wheel, encoder), the magnetization installation and the sampling organization. After the system activated, the wire rope and it has the relative movement, then it can gather the signal.
Displacement locator: Leading wheel rotated a circle, the photoelectric encoder sends out the sampling instruction pulse, realizing equal space sampling.
Magnetization installation: When the wire rope and it has the relative movement, completes to the wire rope axial magnetization.
Sampling organization: When the wire rope and the sensor have the relative movement, the Hall element composed the sampling channel will transform the wire rope magnetic flux leakage change condition into the simulation voltage signal.
8. HUATEC real-time alarm apparatus
The HUATEC real-time alarm apparatus is a portable multi-purpose data acquisition, through the RS232 transmission line to send and save the converted data signal to the computer, make use of the computer CPU formidable function on-line and real-time processing analysis, according to the equivalent threshold value which will set in advance sends out the real-time alarm. One group to give the sensor power supply lithium battery group, the output is 5V. There is an addition charge port to be possible to supply the charge and the power switch.
