标题: [求助]停车场地感线圈的安装请教
我现在涉及到一个5.4米宽的道路，要在上面切一个地感线圈，听说2.5的线绕长只能是30m左右，太长了不行。于是我想按平行四边形来做，想请教大家一下，具体平行四边形的大小和道宽有什么关系？该怎么定这个大小？（四边形是45度的，如果不合适请帮我提一个解决方案），多谢了！

线圈安装规范及故障处理线圈安装规范：一、1．        线圈和馈线应该用绝缘铜线（最小横截面积1.5平方毫米）制作。2．  馈线应该每米至少双绞20圈。3．  应该尽量避免焊接点，万不得已则必须良好接触并做好绝缘。4．  非良好的连接点将导致线圈检测器误操作。5．  馈线将受到外界电磁干扰，所以应该使用屏蔽电缆，屏蔽电缆的屏蔽线在线圈检测器端良好接地。二、1．      线圈如表线圈埋法示意图。2．      线圈匝数及电感量见下表1。三、<p class="MsoNormal" style="MARGIN: 0cm 0cm 0pt 45.05pt; TEXT-INDENT: -36.15pt; LINE-HEIGHT: 150%; mso-list: l3 level1 lfo3; tab-stops: list 18.0pt; mso-char-indent-count: -3.43; mso-para-margin-left: .85gd;">1．           串扰是指两个相邻线圈的馈线或与电源220v之间的至相互干涉。解决的办法为馈线必须双绞，如与供电电源在同一管道内，则馈线必须加屏蔽电缆，并使屏蔽层在一端良好接地（接地电阻不大于5Ω）。2．            为了避免线圈检测器误操作，线圈之间应至少相隔0.3米，并做不同的频率设定。四、1．            所需设备为路面线槽切割工具；2．            为了保护线圈在直角处不被损坏，在直角处应按两个45度角的切割。3．            线槽应该8mm宽，30mm到40mm深。4．            注意从线圈的一角到路边延伸线槽以放馈线五、<p class="MsoNormal" style="MARGIN: 0cm 0cm 0pt 44.9pt; TEXT-INDENT: -36pt; LINE-HEIGHT: 150%; mso-list: l1 level1 lfo5; tab-stops: list 18.0pt; mso-char-indent-count: -3.43; mso-para-margin-left: .85gd;">1．            为了达到最好的效果，应该使用一整根没有接点的电线，从检测器引出，到路面线圈再返回到检测器。2．            应该记住的是：双绞馈线会缩短电线的长度，所以应保证足够长的电线。六、1．            线圈和馈线安放好以后，缝隙应该用沥青填充物充分填好。    表1 ：线圈及馈线横截面积：1.5mm²,电阻率：1.678x10<shapetype id="_x0000_t75" stroked="f" filled="f" path="m@4@5l@4@11@9@11@9@5xe" opreferrelative="t" ospt="75" coordsize="21600,21600">

线圈的大小并没什么,主要是线圈之间不要小于50cm,同时出来的馈线双绞.
