Matters needing attention

1, in addition to the rain outside my torso, other security model can't get wet in the rain, outdoor use must be sealed by the canopy.

2, my torso is around 1 meter to large metal objects, such as iron gate, elevators, large iron column.

3, security installation must fixation, avoid high winds or collision caused by body shaking.

4, away from will produce magnetic field of the object, such as distribution box, electrical equipment, etc.

By specifying

1, line up in turn by, not crowded, not deliberately slow.

2, no alarm, one person out of the door before the second person can pass; After the alarm, the alarm shall stop, can pass.

3, through the door can't collision.

4, through the door plank of the lateral cannot have carried through metal objects.

maintenance

1, the door body surface stains can use wet cloth to wipe.

2, oil stains and difficult to clean up the days that water, alcohol, wipe machine is wiped.

3, need to shut down more than 2 hours a day, to prevent overheating and reduce the performance of work components for a long time.

The working principle of

Gate management principle is produced by the crystals of 3.5 4.95 M sinusoidal oscillation, dividing by the frequency divider is about 7.6 K sine wave, the triode power amplifier input after door plank with coil (7) large coil electromagnetic emission, by the gate 1-6 area to receive coil respectively. After they receive the received signal and the accurate signal were compared, found that after the change, change the acquisition card output level, the CPU in 280 milliseconds for 6 location data acquisition card scanned, determine the metal's location and output display.

2, 1, the structure of the door plank structure: by a big, six small coil, coil of compensating coil and graphite. 2, the structure of the chassis hassles

Three, the detection work processes when the CPU to a group of infrared is blocked, check whether the data acquisition card change to alarm, another group of infrared - > reset detecting
