技术领域Technical Field
本发明涉及光缆相关技术领域，更准确的说涉及一种发热融冰光缆及其自动控制系统。The present invention relates to the technical field related to optical cables, and more precisely to a heat-generating and ice-melting optical cable and an automatic control system thereof.
背景技术Background technique
信息网络是日常生活和生产中的重要基础设施。光纤通信光缆是通讯和信息网络中的重要组成部分，如果光纤通信线路在使用中出现问题会对生产生活造成不良影响。自然灾害是造成光纤通信线路损坏的主要原因，其中，冰雪灾害是较为多发且容易造成大面积破坏的自然灾害。Information networks are important infrastructure in daily life and production. Optical fiber communication cables are important components of communication and information networks. If problems occur in the use of optical fiber communication lines, it will have an adverse impact on production and life. Natural disasters are the main cause of damage to optical fiber communication lines, among which ice and snow disasters are more frequent and easily cause large-scale damage.
光纤光缆的布设方式可分为直埋和架空两种。其中，光纤光缆采用直埋方式可以有效降低或避免因低温、雨雪、冰冻造成的光缆线路覆冰事故。但是采用直埋方式前期施工成本及后期维护成本均较高，且维护不够方便，对于埋设的环境地势也有一定要求，综合考量难以作为普遍应用的光缆布设方式。架空方式是指将光缆架挂在电杆上进行布设，这种方式具有易施工、铺设快、成本低、易维护的优点，是较为常用的布设方式。但是，采用架空方式布设的光缆更易受到自然灾害的威胁，还容易因受到外力影响和自身机械强度减弱导致故障。架空光缆的常用铺设方式包括吊线式和自承式两种，其中吊线式为先用吊线紧固在电杆上，然后用挂钩将光缆悬挂在吊线上，光缆的负荷由吊线承载；自承式为采用自承式结构的光缆，光缆呈“8”字型，上部为自承线，光缆的负荷由自承线承载。The laying methods of optical fiber cables can be divided into direct burial and overhead. Among them, the direct burial method of optical fiber cables can effectively reduce or avoid icing accidents of optical cable lines caused by low temperature, rain, snow, and freezing. However, the initial construction cost and later maintenance cost of the direct burial method are high, and the maintenance is not convenient enough. There are also certain requirements for the burial environment and terrain. Comprehensive considerations make it difficult to use it as a universal optical cable laying method. The overhead method refers to laying the optical cable rack on the pole. This method has the advantages of easy construction, fast laying, low cost, and easy maintenance. It is a more commonly used laying method. However, optical cables laid in an overhead manner are more vulnerable to natural disasters and are more likely to fail due to external forces and reduced mechanical strength. Common laying methods for overhead optical cables include suspension wire type and self-supporting type. The suspension wire type is to first fasten the cable to the pole with a suspension wire, and then hang the optical cable on the suspension wire with a hook. The load of the optical cable is borne by the suspension wire. The self-supporting type is an optical cable with a self-supporting structure. The optical cable is in the shape of an "8", with a self-supporting wire on the upper part, and the load of the optical cable is borne by the self-supporting wire.
在寒冷季节，架空的光缆上常会冻结很大很重的冰凌，加大了光缆的重力负荷，导致光缆承受很大的拉力，导致光缆内部的光纤受力发生应变，轻则产生附加衰减，严重时则会导致光缆断裂、或严重影响光缆的寿命。无论是吊线式光缆还是自承式光缆设计抗拉强度标准都不能承受光缆严重覆冰造成的拉伸力。覆冰严重时，甚至超过10倍缆重以上，造成光缆拉断。In cold seasons, large and heavy ice often freezes on overhead optical cables, increasing the gravitational load on the cables, causing them to bear great tension, which in turn causes strain on the optical fibers inside the cables. This can cause additional attenuation at the least, and in severe cases, it can cause the cables to break or seriously affect their lifespan. The tensile strength standards designed for both suspension cables and self-supporting cables cannot withstand the tensile force caused by severe ice coverage. When the ice coverage is severe, it can even exceed 10 times the weight of the cable, causing the cable to break.
综上，本领域需要设计一种能够应对寒冷冰冻天气的架空光缆，来降 低光缆因覆雪结冰造成断缆事故的概率，确保光缆的正常运行。In summary, the art needs to design an aerial optical cable that can cope with cold and freezing weather to reduce The probability of optical cable breakage due to snow and ice is reduced, ensuring the normal operation of the optical cable.
