Description

输电杆塔的防护方法和系统  Transmission tower protection method and system
技术领域 Technical field
本发明涉及输电设备技术领域,特别是涉及一种输电杆塔的防护方法和系 统。  The invention relates to the technical field of power transmission equipment, and in particular to a protection method and system for a power transmission tower.
背景技术 Background technique
随着国民经济的高速发展, 国民经济运行对电力能源供应的依赖越来越 大。 高压、 特高压骨干输电网的安全运行直接关系到整个电网的安全运行, 更 是关乎国家经济安全和社会稳定。对电网安全运行的外在威胁主要来自三个方 面: 自然灾害, 外部的野蛮施工, 人为破坏。  With the rapid development of the national economy, the national economy is increasingly dependent on the supply of electricity and energy. The safe operation of high-voltage and UHV backbone transmission networks is directly related to the safe operation of the entire power grid, and is related to national economic security and social stability. The external threat to the safe operation of the power grid mainly comes from three aspects: natural disasters, external barbaric construction, and vandalism.
近年来随着全球变暖, 台风、 暴雨、 强雷暴等恶劣气象天候频发, 导致山 洪暴发、 沖毁杆塔地基、 暴风刮断输电线路、 刮倒输电杆塔等自然灾害频发, 对电网安全运行构成越来越大的危险。  In recent years, with global warming, severe weather such as typhoons, heavy rains and strong thunderstorms have occurred frequently, causing frequent occurrences of flash floods, erosion of tower foundations, storm-scraping transmission lines, and scraping of transmission towers. It poses a growing danger.
另夕卜,伴随经济的高速发展和国家重点基础建设施工的高速增长,如新建 高铁、 新建高速公路、 新建高压输电线路和其他新建重点工程的大量上马, 其 施工不可避免的要穿越高压输电走廊, 甚至靠近杆塔施工。 然而, 这些施工单 位通常不具备高压输变电技术的专业知识,缺乏对高电走廊下作业的危险性认 知。这些施工往往会采用多种大型机械施工, 可能会造成危险接近甚至碰线短 路等恶性事故的发生。 靠近杆塔野蛮挖掘等可能会造成杆塔地基损毁、杆塔倾 覆等重大恶性事故。  In addition, with the rapid development of the economy and the rapid growth of national key infrastructure construction, such as the construction of new high-speed railways, new highways, new high-voltage transmission lines and other new key projects, the construction of the high-voltage transmission corridor is inevitable. , even near the tower construction. However, these construction units usually do not have the expertise of high-voltage transmission and transformation technology and lack the danger of working under high-power corridors. These constructions often use a variety of large-scale mechanical constructions, which may cause dangerous accidents such as close to the line and short-circuits. Near the bar tower barren mining, etc., may cause damage to the tower foundation, tower collapse and other major accidents.
还有一些临时施工, 因为施工单位不知情或侥幸心理, 没有告知电力运行 单位, 导致安全监管缺失, 形成事故隐患。 更多的小型、 个人的施工作业, 更 是随心所欲。 而巡查人员不可能全程监控, 等发现问题时往往已经酿成事故或 事故症候, 给电网安全运行带来极大隐患。  There are also some temporary constructions, because the construction unit is not informed or lucky, and has not informed the power operation unit, resulting in the lack of safety supervision and the formation of accidents. More small, individual construction work is more than anything you want. The patrol personnel cannot monitor the whole process. When the problem is discovered, it often causes accidents or accidents, which brings great hidden dangers to the safe operation of the power grid.
人为故意损毁主要是偷盗和破坏。由于国内经济发展的不平衡和社会治安 不良等问题导致盗窃分子对输变电设备不法偷盗行为经常发生,给电力企业带 来极大困扰和重大经济损失。 国内外敌对势力的破坏企图也是电网安全运行的现实威胁,为了应对这些 恐怖威胁, 电力企业和国家安全部门花费了大量的人力物力进行保电行动, 在 特殊时期采取派遣大量技术人员、安全人员到每一个杆塔下值守的方法来应对 恐怖威胁和自然灾害, 耗费了大量的人力物力。 Man-made intentional damage is mainly theft and destruction. Due to the imbalance of domestic economic development and the problems of poor public security, thefts often cause unlawful theft of power transmission and transformation equipment, causing great troubles and major economic losses for power companies. The attempt to destroy hostile forces at home and abroad is also a real threat to the safe operation of the power grid. In order to cope with these terrorist threats, power companies and national security departments have spent a lot of manpower and resources to carry out power conservation actions. In special times, they dispatched a large number of technicians and security personnel to Each tower is guarded by a method of dealing with terrorist threats and natural disasters, which consumes a lot of manpower and resources.
目前国内应对电网的安全威胁主要采用人工巡线, 雇佣当地居民做护线 员, 并少量实验采用直升机、 无人机等现代化手段进行巡线。 在部分重要杆塔 上也有采取技术手段防范盗窃、破坏事件的发生, 但主要是采用视频、 红外等 技术的点对点通信模式,虚警率和可靠性还不尽如人意。巡线工人定期巡视高 压线路, 这项工作是异常艰难的, 巡线工作人员的劳动强度, 护线员的责任心 和护线知识的参差不齐, 野外作业的艰苦和某些线路杆塔难以到达,都会使巡 线工作效果难以保证, 巡线周期长(1 ~ 10 周), 导致线路状态监管的缺位, 这些都给输电线路安全留下隐患。  At present, the domestic security threats to the power grid mainly use manual inspection lines, hiring local residents as line guards, and a small number of experiments using helicopters, drones and other modern means to conduct inspections. In some important towers, technical measures have also been taken to prevent theft and destruction incidents, but mainly the point-to-point communication mode using video and infrared technologies, and the false alarm rate and reliability are still not satisfactory. The line patrol workers regularly inspect the high-voltage lines. This work is extremely difficult. The labor intensity of the line workers, the sense of responsibility of the line guards and the knowledge of the line guards are uneven. The hard work in the field and the difficulty of reaching certain line towers. It will make the inspection work effect difficult to guarantee, and the inspection cycle period is long (1 ~ 10 weeks), which leads to the lack of line status supervision, which leaves hidden dangers to the transmission line safety.

具体实施方式 下面参照附图对本发明进行更详细的描述,其中说明本发明的示例性实施 例。 在附图中, 相同的标号表示相同或者相似的组件或者元素。 BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated. In the figures, the same reference numerals are used to refer to the same or similar components or elements.
图 1为根据本发明实施例的输电杆塔的防护系统 100的结构示意图。输电 杆塔的防护系统 100包括: 无线传感器网络 102、 汇聚(Sink )节点 104和监 控平台 106。  1 is a schematic view showing the structure of a protection system 100 for a power transmission tower according to an embodiment of the present invention. The protection tower 100 of the transmission tower includes: a wireless sensor network 102, a sink node 104, and a monitoring platform 106.
无线传感器网络 102, 布设于输电杆塔的塔身及周围, 用于探测输电杆塔 受到威胁的信号, 并将信号转换成数据。 比如, 当有大型施工机械进入高压走 廊等危险区域、竹木生长接近高压线路等侵入输电杆塔的行为发生时, 无线传 感器网络 102可以监测到该行为,无线传感器网络 102的多个传感器节点可以 将监测到的数据送给汇聚节点 104。  A wireless sensor network 102, disposed around and around the tower of the transmission tower, is used to detect signals that are threatened by the transmission tower and convert the signals into data. For example, when a large construction machine enters a dangerous area such as a high-pressure corridor, and the behavior of the bamboo tree growing close to the high-voltage line invading the transmission tower, the wireless sensor network 102 can monitor the behavior, and the plurality of sensor nodes of the wireless sensor network 102 can The monitored data is sent to the sink node 104.
由于无线传感器网络 102数据传输带宽较低, 无法承载较大的数据量, 并 且节点能量受限, 需要节约通信消耗的能量, 因此需要对不同传感器采集到的 冗余数据进行聚合。 汇聚节点 104即用于连接无线传感器网络 102, 从无线传 感器网络 102获取数据,对获取的数据进行緩存和处理,将处理后的数据通过 移动通信网络进行传输。  Since the wireless sensor network 102 has a low data transmission bandwidth and cannot carry a large amount of data, and the node energy is limited, it is required to save energy consumed by communication. Therefore, it is necessary to aggregate redundant data collected by different sensors. The aggregation node 104 is used to connect to the wireless sensor network 102, acquire data from the wireless sensor network 102, cache and process the acquired data, and transmit the processed data through the mobile communication network.

For example, the infrared sensor 15 can be identified when a person approaches the transmission tower and is ambiguously positioned.
视频传感器 16, 安装于输电杆塔上, 用于响应于汇聚节点 204根据无线 传感器网络 202传送的数据进行的控制,对输电杆塔和输电杆塔连接的输电线 路进行监视。 比如当输电线路跨越江河、 山峰、 高速公路、 高速铁路等区域, 输电杆塔间距离较大, 这些杆塔地理位置重要, 因此需要更好的保护, 这时可 以在这些重要的大跨距输电杆塔上安装视频传感器 16。  The video sensor 16 is mounted on the power transmission tower for monitoring the transmission line connected to the transmission tower and the transmission tower in response to the control of the convergence node 204 based on the data transmitted by the wireless sensor network 202.

图 6为根据本发明实施例的输电杆塔的防护方法 600的流程图。  6 is a flow chart of a method 600 of protecting a power transmission tower in accordance with an embodiment of the present invention.
在步骤 602中, 探测输电杆塔受到威胁的信号, 将信号转换成数据。 各种 传感器可以探测输电杆塔周围的信号。 比如, 地埋震动传感器可以探测输电杆 塔周围地面的震动信号; 杆塔震动传感器可以探测输电杆塔周围的震动信号; 倾斜传感器可以探测输电杆塔的局部水平位移情况;防盗螺栓传感器可以探测 防盗螺栓被破坏的信号; 红外线传感器可以探测入侵信号以及进行模糊定位。  In step 602, a signal that the transmission tower is threatened is detected, and the signal is converted into data. Various sensors can detect signals around the transmission tower. For example, the buried vibration sensor can detect the vibration signal on the ground around the transmission tower; the tower vibration sensor can detect the vibration signal around the transmission tower; the tilt sensor can detect the partial horizontal displacement of the transmission tower; the anti-theft bolt sensor can detect the destruction of the anti-theft bolt Signal; Infrared sensor can detect intrusion signals and perform fuzzy positioning.
在步骤 604中,对探测到的输电杆塔受到威胁的信号转换后的数据进行学 习。 例如, 汇聚节点可以接收传感器发送的数据, 并对其进行学习, 比如, 可 以对输电杆塔破坏事件的声学信号、 震动信号等特征进行学习。  In step 604, the signal converted from the detected transmission tower is subjected to learning. For example, the sink node can receive data from the sensor and learn it. For example, it can learn the characteristics of the acoustic signal and vibration signal of the tower damage event.
在步骤 606中, 根据学习结果对数据划分威胁等级。 比如, 汇聚节点可以 根据学习到的危险挖掘行为的声学信号特征、震动信号特征, 判断是否发生危 险挖掘、 杆塔破坏等行为。 在一个实施例中, 汇聚节点可以将震动等级分为 1 到 10, 十个等级。 其中, 1-5等级为安全, 输电杆塔周围震动较小或无震动; 6-7等级为比较安全, 震动不影响输电杆塔安全; 8-9等级为危险, 如出现挖 掘、 填埋等土方作业; 9级以上为非常危险, 如出现大型施工机械接近、 施工 作业或地震等。  In step 606, the data is divided into threat levels according to the learning result. For example, the aggregation node can judge whether or not dangerous mining, tower damage, etc. occur according to the acoustic signal characteristics and vibration signal characteristics of the learned dangerous mining behavior. In one embodiment, the sink node can divide the vibration level into 1 to 10, ten levels. Among them, the 1-5 grade is safe, the vibration around the transmission tower is small or no vibration; the 6-7 grade is safer, the vibration does not affect the safety of the transmission tower; the 8-9 grade is dangerous, such as excavation, landfill and other earthwork operations Level 9 or above is very dangerous, such as large construction machinery approaching, construction work or earthquakes.
在步骤 608中, 当威胁等级达到预定威胁等级时, 启动对输电杆塔和输电 杆塔连接的输电线路的视频监视。 比如, 汇聚节点可以在威胁等级达到 8级以 上时启动视频传感器。  In step 608, video surveillance of the transmission line connecting the transmission tower and the transmission tower is initiated when the threat level reaches a predetermined threat level. For example, a sink node can start a video sensor when the threat level reaches level 8.
在步骤 610中, 将处理后的数据通过移动通信网络传输给监控平台, 以使 操作人员可以进一步判别危险的具体情况。在一个实施例中, 汇聚节点可以向 监控平台发送告警信号和现场图像。  In step 610, the processed data is transmitted to the monitoring platform through the mobile communication network, so that the operator can further discriminate the specific situation of the danger. In one embodiment, the sink node can send an alert signal and a live image to the monitoring platform.
