安装快速卷帘门地磁环控制时系统故障现象及排除方法

在地磁环控制快速门中,每个单侧通道地磁传感器可同时监测一个电感环,其原理是通过经过的车辆,其金属配件会改变环型传感器值,同时发出信号。

安装磁环:在决定了电环形状后,必须在地面上挖沟槽(5-8毫米宽,30-50毫米深)以安装电环。建议在电环四角挖(45度)斜角槽沟,电环绕斜角减少摩擦。磁环与电控箱连接线一定要每米20个打旋。安装电环线圈的数目绝大部分取决于电环的圆周,电环的圆周越小,线圈的数目就越大。

周圆3米至6米,6圈;圆周6米至10米,5圈;圆周10米至25米,4圈;25米以上3圈。

解决方案:修理探测环,如有必要,因定探测环下的地面(当物体在表面移动时,探测环不可移动),然后重新校准。如果输出继电器开关时产生电感,这将会导致故障,这时必须使用干扰抑制器(例如22欧姆/0.1uf)保护作用。

Fast door to ring in control, each side channel can simultaneously monitor a geomagnetic sensor inductive loop, which works by passing vehicles, the metal parts will change the ring sensor values, while signals.

Mounting ring: After determining the shape of the ring must dig a trench in the ground (5-8 mm wide and 50 mm deep, 30) to install the ring. In the four corners of the proposed cut ring (45 degrees) groove angle, angle around the power to reduce friction. Magnetic and electric control box cable must swirled every 20 meters. Installation of electric loop coil depends on the number of substantially circumferential ring, the smaller circumference ring, the greater the number of coils.

Zhou Yuan 3-6 m, 6 laps; circumference of 6-10 m, 5 laps; circumference of 10-25 m, 4 laps; 25 meters over three laps.

Receiver check failure: the detection loop own switch or red light emitting diode under uncontrolled.

Possible Cause: ground fault; second detection loop interference; When an object moves on the surface, probing the ring moves.

Solution: Repair the detection loop, if necessary, due to the detection loop given under ground (when the object moves on the surface, probing the ring can not move), and then re-calibration. If the output relay to generate inductive switch, which will lead to failure, then you must use suppressors (for example, 22 ohms / 0.1uf) protection.

Possible causes: too much or too winding loop detection (detection loop electromagnetic calorimeter: ideal measurement data 80 to 300u H)

Solution: Replace the detection loop (reduce the number of windings), re-calibrate, change fast gate sensitivity switch, wait about three seconds, and then change the sensitivity switch back to the original settings. If necessary, temporarily cut off the power for about 5 seconds.

Possible causes: too small or too small to detect winding ring (ring detect electromagnetic calorimeter: ideal measurement data 80 to 300u H)

Solution: Replace the probe ring (increasing the number of windings), re-calibrated (with flashing the same treatment program twice).

Possible reasons: interference detection loop, ground fault or short circuit (detection loop electromagnetic calorimeter: Measuring the ideal data 80 to 300u H; checking the insulation resistance, the required data is> 20 megohms).
