Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, in particular to a monitoring device and system for a transmission tower. Background Art

[0002] Electricity occupies an extremely important position in the national economy and is widely used in various fields such as industry, agriculture, transportation, medical care, and communications. It can be said to be a very important energy source and the foundation of modern social civilization. The transmission of electricity is inseparable from transmission towers. In the current power grid, there are a large number of transmission towers, which may be the largest number in all walks of life in the world, and at the same time one of the most difficult to manage and maintain industry assets. For example, under the influence of natural environment and external conditions, factors such as earthquakes, lightning strikes, landslides, bad weather, aging oxidation, and potential human theft and destruction will bring certain safety hazards to transmission towers. The foundation of transmission towers is prone to slippage, tilting, cracking, etc., which can cause deformation, tilting, and even collapse of transmission towers. Once an accident occurs to the transmission towers of important transmission lines, it will require maintenance at the least, or cause power outages and cause serious economic losses. Therefore, monitoring and maintenance of transmission towers is extremely important.

[0003] The monitoring methods of transmission towers include: manual inspection, measuring various data of transmission towers on site; real-time monitoring by monitoring equipment, obtaining various data of transmission towers by various sensors. Among the current monitoring equipment of transmission towers, such as the transmission tower monitoring device disclosed by announcement number "CN214173339U" and subject name "A transmission line tower tilt online monitoring device", it is installed with a variety of sensors, but each sensor is relatively scattered and not concentrated enough. Since the top of the transmission tower is already installed with various necessary devices for power transmission such as wires and cross beams, it is cumbersome and very inconvenient to install the above-mentioned non-integrated monitoring device on the top of the transmission tower. After the necessary devices for power transmission and the above-mentioned devices are installed, if the equipment on the top of the transmission tower needs manual maintenance or replacement of components in the future, it is very likely to cause physical interference to the maintenance workers, which is not convenient for construction.

[0004] In view of this, there is a need for an integrated transmission tower monitoring device that is easy to install and maintain. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a monitoring device and system for transmission towers. By arranging a monitoring device on the transmission tower and sending monitoring information through the monitoring device, the defect that the current transmission towers need manual inspections is solved, and the data can be stored in severe weather such as thunderstorms and sandstorms, and the complete data can be sent after the weather improves to ensure the data is accurate.

[0006] The utility model discloses a monitoring device for a transmission tower through an embodiment, including a housing, a gain antenna arranged outside the housing, a control circuit board arranged inside the housing, an information processor, a memory, a battery holder, a sensor module and a communication module arranged on the control circuit board, and a battery pack arranged on the battery holder. Among them, the gain antenna is electrically connected to the communication module for sending communication signals; the sensor module is electrically connected to the information processor, and the signal collected by the sensor module is processed by the information processor; the memory is electrically connected to the information processor, and the model signal of the sensor is stored in the memory after being processed by the information processor, and of course the information processor can also process the information stored in the memory; the communication module is electrically connected to the information processor, and the data processed by the information processor can be modulated by the communication module and sent. Finally, the battery pack is used to power the electrical appliances of the entire monitoring device, including powering the information processor, the memory, the gain antenna, the sensor module or the communication module.

[0007] Furthermore, the sensor module includes an inclination angle sensor, a vibration sensor, a temperature sensor and a humidity sensor, which are respectively used to sense the inclination information of the transmission tower, whether there is vibration, and the temperature and humidity of the current environment of the transmission tower.

[0008] Furthermore, the communication module includes one or more of NB-IoT communication module, 4G communication module, 5G communication module, ZigBee communication module or GPRS communication module, which is used to send information collected by the sensor module or receive control information of the monitoring device for the transmission tower from the control personnel. When multiple communication methods are used, the fault tolerance rate of information transmission can be improved.

[0009] Furthermore, the gain antenna includes a first antenna and a second antenna, the frequencies of the first antenna and the second antenna are different, and antennas with different frequencies can also improve the fault tolerance of information transmission.

[0010] Furthermore, depending on the use environment, a wind speed and direction sensor can be installed on the outside of the casing so that the staff can understand the wind direction environment of the transmission tower in real time.

[0011] Furthermore, a charging device is provided on the shell, and the charging device is connected to the battery pack.

[0012] Furthermore, the charging device includes one or both of a solar panel and a wind turbine. The solar panel or the wind turbine can effectively supply power to the battery pack, eliminating the disadvantage of regularly replacing batteries for the monitoring device for the transmission tower.

[0013] Furthermore, the housing includes an upper housing and a lower housing; the upper housing and the lower housing are connected by a hinge. It is worth noting that after the upper housing and the lower housing are buckled together, a cavity is formed inside the housing, and the above-mentioned information processor, memory, battery holder, sensor module and communication module are sealed inside. Preferably, a sealing ring is also provided between the upper housing and the lower housing to seal the entire transmission tower monitoring device to prevent water vapor and dust from entering the interior of the housing.

[0014] In order to achieve the above-mentioned purpose, the utility model also discloses a monitoring system for transmission towers, which includes the above-mentioned transmission tower monitoring device, and also includes a cloud server and a mobile control terminal. Among them, the transmission tower monitoring device is installed at the center of the transmission tower or other key monitoring positions according to needs; the cloud server is responsible for storing the tower body information, tilt angle, health status, equipment setting information, equipment information and other data monitored by the transmission tower; the mobile control terminal is a control device installed on the mobile terminal device of the docking platform data used by the installation and inspection personnel. The staff monitors the transmission tower in real time through the control device, and sends an alarm to the control device of the responsible personnel when an abnormal situation occurs, reminding them to deal with it in time. At the same time, the transmission tower monitoring device, the cloud server and the mobile control terminal also have the function of two-way communication with each other. Of course, it is worth explaining that the program part of the cloud server and the mobile control terminal belongs to the prior art, and the above functions can be achieved based on many existing solutions, so there is no need to repeat them here.

[0015] Furthermore, the mobile control terminal includes a mobile phone control terminal or a mobile computer control terminal. When a mobile phone control terminal or a mobile computer control terminal is used as the mobile control terminal, the corresponding control software is usually installed on the mobile phone. Of course, the mobile control terminal can also be a control device specially made for the monitoring system of the transmission tower. The mobile control terminal is a mobile control device used by installation and inspection personnel to connect to the cloud server and the monitoring device for the transmission tower. The staff monitors the transmission tower in real time through the mobile control terminal, and sends an alarm to the responsible personnel when an abnormal situation occurs, reminding them to deal with it in time.

[0016] The technical principle of the utility model is: during installation, since the entire device is an integral unit arranged in a shell, it is easy to install. When in use, the transmission tower monitoring device obtains historical data such as the historical average inclination angle, standard deviation, and cumulative number of detections on the day under the normal mode of the transmission tower according to the communication module. Specifically, the transmission tower monitoring device collects relevant information of the transmission tower, including inclination angle information (X, Y and Z axis data), vibration information, temperature and humidity information, etc. The information processor calculates the X, Y and Z axis angles based on the above information, removes the maximum and minimum data from the data with a period of several seconds, takes the average value, and feeds back the data of the actual situation; calculates the maximum amplitude, removes the maximum and minimum data from the data with a period of several seconds, takes the average value and the maximum amplitude of the initial average inclination angle; calculates whether the change in acceleration exceeds the set vibration alarm threshold; calculates the z direction angle, removes the maximum and minimum data from the data with a period of several seconds, takes the average value, and calculates the standard deviation of the inclination angle of this period. Finally, the output includes x, y, and Z inclination angles, inclination direction, maximum amplitude, detection duration, average inclination angle of this round, standard deviation of inclination of this round, and stability factor data. At the same time, the monitoring device for transmission towers can also set the data reporting cycle, based on the results of the reported data processing; at the same time, local storage supports data storage, and if the report fails, it will be stored locally for the next report. The tilt alarm threshold, vibration alarm threshold, amplitude alarm threshold, etc. can be set. When the detected data is greater than the set alarm threshold, the device must report the original data immediately after entering this mode, and enter the data reporting state. The status is reported every reporting interval, and the number of times is limited.

[0017] Compared with the prior art, the utility model has the following beneficial effects: the monitoring device for the transmission tower adopts an integrated one-piece setting, which is easy to install, is not affected by buildings and protected objects, can be used alone without wiring, and does not require the installation of a large number of pipelines and auxiliary facilities.

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. Of course, the specific embodiments described below are only for explaining the technical solution of the present invention, rather than for limiting the present invention. In addition, the parts described in the embodiments or drawings are only examples of the relevant parts of the present invention, rather than the entirety of the present invention. At the same time, based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field should naturally belong to the protection scope of the present invention.

[0028] like Figure 1-4 As shown, the utility model proposes a monitoring device for a transmission tower through the following embodiments, including a housing 2, the housing 2 is installed by a mounting bracket 1, the housing 2 is divided into an upper housing 8 and a lower housing 3, a sealing ring 7 is also arranged between the upper housing 8 and the lower housing 3, a first antenna 9 and a second antenna 10 are arranged outside the housing 2, a control circuit board 4 is arranged in the housing 2, a battery holder 5 is arranged on the control circuit board 4, and a battery pack 6 is arranged on the battery holder 5. Among them, an information processor, a memory, a sensor module and a communication module are integrated on the control circuit board 4, and the components are connected through the wiring electrical signals on the control circuit board 4. The battery pack 6 is placed on the battery holder 5 to supply power to the entire device. When in use, the monitoring device for the transmission tower is installed in the center of the transmission tower or other key monitoring positions according to the installation requirements.

[0029] In this embodiment, the sensor module provided in the housing includes a tilt angle sensor, a vibration sensor, a temperature sensor, and a humidity sensor. They are respectively used to sense the tilt angle information of the transmission tower, whether there is vibration, and the temperature and humidity of the current environment of the transmission tower. In this embodiment, the communication module in the monitoring device for the transmission tower adopts a 4G communication module and an NB-IoT communication module. Specifically, the 4G communication module and the NB-IoT communication module each correspond to an antenna, and two information transmission methods are used, which has higher fault tolerance.

[0030] When in use, the monitoring device for transmission towers obtains historical data such as the historical average inclination, standard deviation, and cumulative number of detections on the day under the normal mode of the transmission tower according to the communication module. Specifically, the monitoring device for transmission towers collects relevant information of the transmission tower, including inclination angle information (data of the X, Y and Z axes), vibration information, temperature and humidity information, etc. The information processor calculates the X, Y and Z axis angles based on the above information. Taking a 20-second cycle as an example, the maximum and minimum data are removed from the data, the average value is taken, and the data of the actual situation is fed back; the maximum amplitude is calculated. Taking a 0.5-second cycle as an example, the maximum and minimum data are removed from the data, the average value is taken, and the maximum amplitude of the initial average inclination is calculated; whether the change in acceleration exceeds the set vibration alarm threshold is calculated; the angle in the z direction is calculated.

At the same time, the transmission tower monitoring device can also set the data reporting cycle. According to the results of the reported data processing, if the report fails, it will be stored locally and reported next time. The maximum amount of stored data is limited by the storage capacity of the memory and the manual settings in the system. The tilt alarm threshold, vibration alarm threshold, amplitude alarm threshold, etc. can be set. When the detected data is greater than the set alarm threshold, the device must report the original data immediately after entering this mode and enter the data reporting state.

At the same time, the transmission tower monitoring device, the cloud server and the mobile control terminal also have the function of two-way communication with each other. It is worth noting that in this embodiment, the cloud server and the mobile control terminal are implemented using existing technologies.
