Description
技术领域technical field
本发明涉及物联网技术，电力输电线路技术以及监测系统技术领域，更具体地说，是涉及一种基于NB-IoT技术的杆塔倾斜状态监测系统。The present invention relates to the technical fields of Internet of Things technology, power transmission line technology and monitoring system, and more specifically, relates to a tower tilt state monitoring system based on NB-IoT technology.
背景技术Background technique
输电线路杆塔是高压电能输送的基础设施之一，随着高压输电的不断发展，杆塔在承担高压输电线路中起着举足轻重的作用，同时，输电线路杆塔的使用量在迅速增加并且分布广泛。输电线路杆塔基座的牢固和稳定，对输电线路十分重要。设置在一些不良地质区（例如采空区、滑坡区、沼泽水田区、海边台风区、沙地及高盐冻土区）的杆塔容易发生一定程度的倾斜。而强风，大雨，暴雪，冰雹等恶劣自然天气的影响同样可能引起杆塔的倾斜甚至变形，进而使输电线路受力不均，造成电气安全距离不够，影响线路正常运行，久而久之，造成杆塔的坍塌，导致整条输电线路停运，造成巨大的经济损失。但是在杆塔倾斜发生的初期，倾斜度较小，难以用肉眼直接观察判断杆塔是否发生倾斜。因此，为保证输电线路的安全运行，有必要建立杆塔倾斜状态的监测系统，以及早发现杆塔倾斜状态并及时加以维修。Transmission line towers are one of the infrastructures for high-voltage power transmission. With the continuous development of high-voltage transmission, towers play a pivotal role in undertaking high-voltage transmission lines. At the same time, the use of transmission line towers is rapidly increasing and widely distributed. The firmness and stability of the base of the transmission line tower is very important for the transmission line. Towers installed in some unfavorable geological areas (such as goaf areas, landslide areas, swamp paddy fields, seaside typhoon areas, sandy land and high-salt permafrost areas) are prone to inclination to a certain extent. However, strong wind, heavy rain, blizzard, hail and other severe natural weather may also cause the tower to tilt or even deform, which will cause uneven force on the transmission line, resulting in insufficient electrical safety distance, affecting the normal operation of the line. Over time, it will cause the tower to collapse. The entire transmission line will be out of service, resulting in huge economic losses. However, in the initial stage of the tower tilt, the inclination is small, and it is difficult to directly observe with the naked eye to judge whether the tower is tilted. Therefore, in order to ensure the safe operation of the transmission line, it is necessary to establish a monitoring system for the inclination state of the tower, to detect the inclination state of the tower early and to repair it in time.
现有技术中，传统的人工巡线监测杆塔倾斜状态的方式，工作效率低下且困难较大。而现有的利用通信技术的杆塔监测系统中，其通信方式大多依赖于GSM/GPRS网络与运营商的基站，相对简便，易于部署，但运营成本与系统整体功耗均较高，同时，在接入能力、抗干扰能力以及通信覆盖能力上有所不足。公开号为106403896A《基于LoRa技术的杆塔倾斜状态监测系统》公开了一种基于LoRa技术的杆塔倾斜状态监测系统，利用LoRa技术降低系统的功耗，虽然加强了通信距离，但是需在杆塔附近另行架设LoRa基站。公开号为107101615A《基于蓝牙通信的输电线路杆塔倾斜监测系统及其应用方法》公开了一种基于蓝牙通信的输电线路杆塔倾斜监测系统及其应用方法，使用户能够使用智能手机及时获取杆塔倾斜的相关信息，以采取对杆塔倾斜的应对措施，但是其存在如前所述的接入能力、抗干扰能力以及通信覆盖能力上有所不足的问题。In the prior art, the traditional way of manual line inspection to monitor the inclination state of towers is inefficient and difficult. In the existing tower monitoring system using communication technology, most of its communication methods rely on the GSM/GPRS network and the base station of the operator, which is relatively simple and easy to deploy, but the operating cost and the overall power consumption of the system are high. At the same time, in Access capabilities, anti-interference capabilities, and communication coverage capabilities are insufficient. Publication No. 106403896A "Tower Tilt Status Monitoring System Based on LoRa Technology" discloses a LoRa technology-based tower tilt status monitoring system, which uses LoRa technology to reduce system power consumption. Although the communication distance is enhanced, it needs to be installed separately near the tower. Set up a LoRa base station. Publication No. 107101615A "Bluetooth Communication-Based Transmission Line Tower Tilt Monitoring System and Its Application Method" discloses a transmission line tower tilt monitoring system and its application method based on Bluetooth communication, enabling users to use smart phones to obtain timely information on tower tilt Relevant information to take countermeasures against tower tilt, but it has the problems of insufficient access capability, anti-interference capability and communication coverage capability as mentioned above.
