The windows system of wire rope computer detector is the GB system renewal product which based on the DOS software theory and the real time display alarm guiding ideology utilizes Visual Basic6.0 the programming language foundation, carries on the compilation to become.

This system hardware part uses the domestic and foreign advanced magnetic sensor and the independent research and development sampling module unifies, through RS232 (or USB) main line driving, directly storage data in computer.

This system software part is in the wavelet transformation analysis foundation, in utilizing Visual Basic 6.0 programming language foundation, carries on the compilation to become. Achieve the functions such as data acquisition and control, data analysis, data display, data storage and so on. Increase the visible characteristic in the DOS software function, and by its unique tendency continuously to track the way, may continuously, the dynamic observed data signal and its the change situation, and the real time display obtained result and sends out the alarm; Software increased the automatic evaluation function; In the partial flaw demonstrated on increased cross section and the total sectional area percentage; Software and Windows are completely compatible, suits to user's inertia operation, uses the Word files form production examination report.

This system software may compatible wire rope computer detector DOS software sampling data format, and can analysis processing to it.

The windows system took an independent operating procedure and the safe examination system, can conveniently be suitable for each kind of modern computer, and completes a series of examinations procedure.

3. 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.

4. 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.
