[23] 以下结合技术方案和附图详细叙述说明本发明的最佳实施例。
[24] 附图 1给出了基于碳纤维一玻璃纤维复合编织网的电加热融雪、 化冰自动控制 系统。 碳纤维-玻璃纤维复合编织网的施工方式为： 首先在待加热体基础层 2上 设置隔热层 3， 厚度控制在 10〜30mm， 以减少向下传输的热量损失； 在隔热层 3 之上铺设导热层 4， 厚度在 5〜10mm左右， 通常希望该层材料具有较大的导热系 数； 然后将经过电绝缘、 粘沙处理的碳纤维-玻璃纤维复合编织网 1平整摊铺， 复合编织网中的经向碳纤维束加热体 9与待加热体短边平行， 釆用导电银胶和电 线将编织网中碳纤维束加热体两侧的电接点 6通过串联和并联的方式连接起来， 将引出的导线连接到具有保护功能的大功率可控电源 7上； 在纤维编织网上铺设 导热层 4， 并在导热层 4不同部位的表层安装测温元件 5， 为了提高热传导速度， 降低系统功耗， 可将导热层 4的厚度控制在 20〜50mm。
[25] 所釆用的碳纤维 -玻璃纤维复合编织网是由经向等间距排列的碳纤维束 9和纬 向等间距排列的玻璃纤维束 10交叉编织而成， 网格的大小和碳纤维束的截面尺 寸可以根据现场建筑材料的性质和对融雪化冰的要求定制。 碳纤维-玻璃纤维 复合编织网 1的表面釆用环氧树脂进行电绝缘处理， 并在环氧树脂层 11的表面粘 沙， 形成与基体材料粘结力强的粘沙层 12， 对待加热体起到阻裂、 增韧和加固 的作用。
[26] 测温元件 5实吋测量待加热体表层的温度， 并与路面的风速、 积雪和结冰厚度 、 空气温度、 融雪化冰的期望吋间等参量作为数字 PID温度控制系统 8的控制参 数输入系统， 数字 PID温度控制系统 8根据上述参数， 优化调整 PID的控制参数， 调节大功率可控电源 7的工作电流， 从而控制碳纤维-玻璃纤维复合编织网 1的 发热功率， 改变路面的工作温度， 达到融雪、 化冰目的。
[27] 所釆用的碳纤维 -玻璃纤维复合编织网是由经向等间距排列的碳纤维束 9和纬 向等间距排列的玻璃纤维束 10交叉编织而成， 网格的大小和碳纤维束的截面尺 寸可以艮据现场建 https:〃onsite.verisign.com/services/WorldIntellectualPropertyOrga nizationWIPOCustomerCA/digitalidCenter.htm筑材料的性质和对融雪化冰的要求 定制。 碳纤维-玻璃纤维复合编织网 1的表面釆用环氧树脂进行电绝缘处理， 并 在环氧树脂层 11的表面粘沙， 形成与基体材料粘结力强的粘沙层 12， 对待加热 体起到阻裂、 增韧和加固的作用。
[28] 釆用 400x400x40 mm的碳纤维 -玻璃纤维复合编织网加热板对系统的加热性能 进行考核。 加热板由三层构成： 首先是 30mm的混凝土层， 然后是网格尺寸为 10 mmxlOmm的经过处理的碳纤维-玻璃纤维复合编织网， 最后是 10mm厚的混凝 土层。 此外， 釆用 30mm厚的泡沫板对整个板的四周和底部进行热绝缘处理， 温 度传感器则被布放在加热板的中间。
[29] 试件中碳纤维束的平均电阻为 24.5欧姆， 如果将所有的碳纤维束釆用并联形式 连接到加热电源， 则总的加热电阻约为 0.74欧姆， 而全部釆用串联形式则为 784. 06欧姆。 因此， 通过改变碳纤维束的接线形式， 整个板的加热电阻可以在 0.74〜 784.06欧姆之间调节。
[30] 实验中， 将碳纤维束通过串并联结合的方式连接到 24V/15A的直流电源， 如图 4 所示。 为了保证环境温度不变， 将整个加热板置于冰箱中。 当环境温度为零下 1 6.6度吋， 通过本系统可以使试件的表面温度在 150分钟的吋间内上升到 71.5度， 平均加热速率为 0.59°C/min， 如图 5所示。 图 6是升温过程中整个加热板的电阻率 变化曲线， 可以看出， 电阻率从 9.95Ω·ΟΏ下降到 9.75Ω·ΟΏ， 最大降幅为 2.01 % ， 这表明本系统在较大的温度范围内具有稳定的加热电阻。
