Index Terms-de-icing, mobile robot, transmission line, deicing tool. I. INTRODUCTION Atmospheric icing structures, such as overhead transmission lines of sand in many countries, peoples lives brought about serious consequences, you can make a huge impact.It is generally known, occurred in 2008 in Quebec, Canada in 1998 in southern China.Modern transmission line de-icing methods, including hot-melt method and mechanical methods to break the ice additives 1-6. However, thermal methods have several shortcomings. First, the use of high current is applied to the results of the transmission lines in high-energy and mechanical methods. As evidenced by the literature. 7, thermal method requires about 100 times more energy than the mechanical method to force the ice off. Second, the thermal method is usually used for de-icing of the conductors, but there is no ground wire (GWS). In contrast, mechanical methods can be easily applied to the GWS very little or no modification.Conductor using different materials and GWS, GWS loaded with heavy ice can be widely extended and too close to the conductor, leading to flashover Cause short circuits. Therefore, the de-icing work for the GWS must be seriously considered. Line the ROV er, tele operation transmission line de-icing to become demand requirements. The third prototype has been developed to the generation of this robot from 2000 8 and improve the work in progress 9 10. In this article, the introduction of the latest developments and refurbishment Line the ROV er. Extension of time with the standard-voltage lithium-ion battery and a new type of low voltage DC motor is put into use, the duration does not increase the weight robot. A new wireless transmission module, it can be an arbitrary expansion of two-way transmission. The electrical control box is used to seal joints to deal specifically with, and a new, waterproof to improve these two robots. The de-icing tests were conducted two outdoor experiments line. According to the experimental results, we modify the de-icing tools, and a higher performance. All of the above elements will be discussed in detail in the following discussion section. Two.Transmission line de-icing machine technology development background batteries and update the driver of the motor to the important role of the motor in the robot motion system. A new type of lightweight but powerful brushless DC motor with low voltage (48 volts and 340 volts) has provided the current robot. With DC motors, linear velocity of the robot can reach 1.5 m / sec. Battery technology advances very quickly, and its innovations have led to a large number of new product development in many areas of Many outstanding features such as light weight cycle long life, and no memory effect, a lithium-ion battery (voltage 48 V) power package applications and use nickel-metal hydride batteries. Rated capacity of 2.2Ah battery to increase 18.2Ah output power improved significantly. Sufficient to provide the daily operation of the energy and the battery weight significantly decreased from 10.6 to 6.9 kilograms, at the same time. Table 1 shows the improvement of current robot specifications B. Updating the wireless transmission modules and remote controller Based on the same frequency hopping and spread spectrum in the Line ROV er third generation technology, a new wireless transmission module is applied to the Improve the robot. This smaller, lighter, and more than the price than the previous. In addition, there are only eight digital channels and six modules in the previous one-way analog channels, digital transmission can expand any two-way transmission of channels and analog channels in order to be modified according to customer requirements. Can be seen from Table 1, the remote control range to expand to a sharp increase from 0.8 km to 6.4 km As we all know, the use of high-quality commercial components can reduce design time and production costs. To this end, the portable remote control model aircraft use lithium-ion battery and a real-time voltage. This controller is lighter, higher reliability and easier operation than the previous generation C. updated waterproof Consider the robots actual working conditions in the de-icing process, should be noted that all the components of the water, in particular, leaving the cable plug in the air. Good business waterproof connector water resistance is used as a connection between the motor and control box and battery. In addition, the electrical control box and the processing of the lithium-ion battery and sealing. All of these methods to ensure that the robot waterproof and verification through field trials. Figure 1 shows the prototype with a remote control unit improve Line ROV er the rights. Go out. 18.6 mm in diameter is bare, and other diameter 26.4mm rubber cover. Use several to the formation of ice nozzle with 10 hours of water spray intermittently. The ambient temperature is below 13 degrees Celsius to zero. Coated with ice oval cross-section diameter wire measurements in two lines of about 63 mm A. de-icing experiments A smooth start of the experimental progress of the bare conductor, but twice to stop before the process is complete. It robots seem to be having an ice resistance block and stop the robot station. We can see that when the robot passed through the line, there are still some ice still can. (The former and the latter two) three traction wheels standing on the ice completely correct, the middle wheel to hang a line, resulting in slipping in situ robot. On the other side, it was discovered that the robot ran with smooth rubber cover ray experiment on the bare line apply ice along the lines of the rapid decline, the robot hit the ice. After careful analysis of the results, the area between the accumulation of ice de-icing tools and bare conductor. In previous experiments in the creation of ice, compared to the adhesion strength between ice and ice hardness of the conductor were higher than before. Thus, a possible explanation is that due to the extreme hardness of coated ice, it does not break into small pieces, but the formation process than a big impact. The gradual accumulation of ice, and finally block robot. Although there are some differences between the two previously mentioned, the reason to stop can be attributed to the experience of the conductor after leaving the ice robot, and attributed to the large area between the de-icing tools and wire Discuss the experimental results is proposed to improve the style of de-icing tool. Two to install the baffle behind the knife, can be seen in Figure 7. Proved by improving the performance of the subsequent test, and no other station in the process of de-icing. With regard to the situation represented in the diagram. 5, it can be attributed to ice and low adhesion strength between the lines outside the presence of rubber 11. In addition, the baffle of improved de-icing tool in order to speed up the process of de-icing, you can uninstall if appropriate, for example, if the hardness of ice is not too high a smooth and quickly cleared, or if the line is a rubber cover. Then, the robot successfully moved on overhead 500 kV EHV Liu zhou Bureau, ground power transmission of the China Southern Power Grid Company in December 2009, and obtained the good reputation of the user. In this paper, in sustained development Line ROV er, teleoper ted robot de-icing of overhead transmission lines, because it appeared in 2000. New features, such as a low voltage DC motors, lithium-ion battery, the wireless transmission modules can be introduced to expand with two-way transmission and waterproof control box. All these measures increase the duration, to improve the reliability of the robot. De-icing tool on the basis of the outdoor de-icing, modify experiments and better performance verification testing the improvement Line ROV er has been successfully in southern China of a 500 kV overhead ground wire run 外文资料翻译译文 输电线除冰机些人的改进 摘 要 本文介绍了改进 输电线除冰机 ，架空输电线路除冰机器人线。低电压直电动机和锂离子电池用于增加持续时间不增加机器人的重量。无线传输模块，可以任意扩大双向传输。电气控制箱和电池是专门处理和一种新型防水联合使用。所有这些措施提高机器人的防水性和提高其可靠性。室外进行除冰实验，除冰工具，然后根据结果修改。一个测量性能的改善。 关键词： 除冰，移动机器人，输电线路除冰工具。 一， 导言 大气 结冰可以使一个巨大的影响如架空输电线路的人造结构在许多人的生活带来严重的后果国家。它一般发生在魁北克省，加拿大在 1998 年和 2008 年的中国南方。现代输电线路除冰的方法，包括热融化的方法和机械方法，打破冰添加物。然而，热的方法有几种缺点。首先，使用大电流应用到输电线路在高能耗的结果与机械方法。作为证明文献。热方法需要更多的能量的 100 倍左右比机械的方法来迫使冰脱落。其次，热方法通常用于除冰的导体但没有接地线（ GWS）。相比之下，机械方法可以很容易地应用到 GWS 很少或根本没有修改。由于导体使用不同的材料和 GWS， GWS 满载重冰区可广泛延伸和太靠近的导体，导致闪络造成短路。因此，为 GWS 除冰工作必须认真考虑。 输电线除冰机 ，可以远程操作机器人输电线路除冰成为需求要求。已经发展到第三个原型代从 2000 年和改进工作这个机器人是正在进行中。在本文中，最新的发展和整修 输电线除冰机 介绍。与标准电压的锂离子电池和一种新型的低电压直流电动机投入使用，使工期不增加重量的情况下延长时间机器人。一个新的无线传输模块，它可以是任意扩大双向传输。电气控制箱是专门处理和新型用于密封接头，防水改善这两个机器人。除冰试验进行了两个室外实验线。 根据实验结果，我们修改除冰工具，并得到了一个更高的性能。所有上述内容将在下面的讨论节中详细讨论。 二。 输电线除冰机 科技发展背景 A.电池和电机的更新驱动电机在机器人的重要作用运动系统。一种新型的轻量级但功能强大的无刷直流电机与低电压（ 48 伏与 340 伏）已提供了当前的机器人。与此 DC 电机，机器人的线速度可以达到 1.5 米 /秒。电池技术进步非常迅速，其创新导致大量的新产品开发许多领域。由于其中许多突出特点如重量轻循环寿命长，并没有 “记忆效应 ”， 1 锂离子电池（电压为 48 伏）的包应用电源与之前使用的镍氢电池。由 于额定容量从 2.2Ah 电池增加18.2Ah，输出功率显着提高。足够可以提供多个日常运作的能量和电池的重量显着下降 10.6公斤至 6.9 公斤，在同一时间。表 1 显示了改进目前的机器人规格。 B.更新的无线传输模块和远程控制器 基于同样的跳频和扩频在的 输电线除冰机 的第三代技术，一个新的一种无线传输模块被应用到提高机器人。这更小，更轻以及多价格比前。此外，还有只有 8 个数字通道和 6 个单向类比通道以前的模块，而数字传输现在可以扩大渠道和类比通道任意双向传输，以便进行修改根据客户的要求。可以看出，远程控制范围也扩大急剧增加 ，从 0.8 公里至 6.4 公里 众所周知，使用高品质的商业组件可以减少设计时间和生产成本。为为此，航模使用的便携式遥控器锂离子电池和一个实时的电压。这种控制器是比与上一代更轻
