Background Art

[0002] High-voltage line towers are an important part of the power transmission lines of the power sector. Due to the limitations of my country's terrain and geological conditions, power transmission towers are inevitably built on the natural slopes of steep mountains, and are subject to natural damage such as wind, rain, snow, and ice, which poses a great threat to the stability of the power transmission tower base. Traditional manual inspections are both labor-intensive and inefficient, and cannot effectively monitor the stability of the tower base. Therefore, establishing a three-dimensional monitoring system for the stability of the power transmission tower base can prevent and reduce accidents and improve the safety of the power system.

[0021] The technical solution of the present invention is further described below in conjunction with the accompanying drawings, but is not limited thereto. Any modification or equivalent replacement of the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention should be included in the protection scope of the present invention.

[0022] The present invention provides a data-driven digital management system for multi-source stereoscopic monitoring and intelligent operation and maintenance of power transmission and transformation tower bases. Figure 1 and Figure 2 As shown, it includes a multi-source stereoscopic monitoring system 1, a data management and analysis system 2 and an interface display system 3, wherein:

[0023] The multi-source stereo monitoring system 1 is used to collect relevant monitoring data of the tower base and the tower pole, and the monitoring data includes: for the tower base, mainly collecting data such as stress, settlement, ground temperature, groundwater, foundation deformation, etc., for the tower pole, mainly collecting data such as inclination, wind speed, rainfall, node displacement, local cracks, temperature, etc.;

[0024] The data management and analysis system 2 is used to store, manage and analyze the monitoring data collected by the multi-source stereo monitoring system 1;

[0025] The interface display system 3 is used to display the monitoring results of the multi-source stereoscopic monitoring system 1 through a mobile device with a mobile processor. The mobile terminal can display the monitoring data display and management module, the on-site real-time monitoring module and the monitoring alarm module.

[0026] like Figure 3 As shown, the multi-source stereo monitoring system 1 is deployed and installed according to the environmental characteristics and monitoring requirements of the transmission and transformation tower to collect relevant monitoring data of the tower base and tower body. The multi-source stereo monitoring system 1 includes a tower base monitoring system 4, a tower pole monitoring system 5, a control and transmission system 7, and a power supply system 8, among which:

[0027] The tower base monitoring system 4 is used to monitor the relevant data of the tower base stability, including a tower base monitoring device 41. The tower base monitoring device 41 needs to be buried in the soil layer around the tower base or at the foundation of the transmission tower according to the monitoring requirements. The tower base monitoring device 41 mainly provides data such as stress, settlement, ground temperature, groundwater, foundation deformation, etc. The specific monitoring content can be adjusted according to the actual situation;

[0028] The tower monitoring system 5 is used to provide data on the environment around the transmission and transformation tower, including a tower monitoring device 51 and a tower integrated mounting mechanism 52. The tower monitoring device 51 is mounted on the tower integrated mounting mechanism 52. The tower integrated mounting mechanism needs to be arranged on the tower as required. The tower monitoring device 51 mainly provides data such as the inclination, wind speed, rainfall, node displacement, local cracks, temperature, etc. of the tower and on-site monitoring images. The specific monitoring content can be adjusted according to the actual situation.

[0029] The tower base monitoring device 41 and the tower pole monitoring device 51 are connected to the control and transmission system 7 and the power supply system 8 via a sealed cable 6, and the sealed cable 6 is fixed to the tower base and the tower pole;

[0030] The control and transmission system 7 includes a computing processor, an embedded operating system, a data storage device, a signal acquisition module and a GPRS data transmission module, which can realize automatic control, data acquisition and analysis of a multi-source stereo monitoring system;

[0031] The power supply system 8 includes several solar panels and batteries. The number of solar panels is determined according to the number of monitoring instruments and energy consumption, and can provide power to the tower base monitoring system 4, the tower pole monitoring system 5, and the control and transmission system 7.

[0032] like Figure 6 As shown, the tower integrated mounting mechanism 52 includes a first hoop member 521, a second hoop member 522, a hoop fastening member 523, a vertical mounting rod 524, a vertical mounting plate 525, a first instrument mounting member 526, a second instrument mounting mechanism 527, a first monitoring instrument 511, and a second monitoring instrument 512, wherein:

[0033] The first hoop member 521 and the second hoop member 522 are fixed to the position to be monitored on the tower pole through the hoop fastening member 523;

[0034] The vertical mounting rod 524 is fixed between the installed first hoop member 521 and the second hoop member 522, and the arrangement spacing thereof is set according to specific monitoring requirements;

[0035] The vertical mounting plate 525 is mounted on the vertical mounting rod 524, which can expand the working surface to ensure the installation of the monitoring instrument;

[0036] The first monitoring instrument installation component 526 is a box structure with a flip door slidingly provided on one side, and is used to install the first monitoring instrument 511;

[0037] The first monitoring instrument 511 is a monitoring instrument that does not need to be externally installed, such as a tower tilt detector;

[0038] The second monitoring instrument mounting member 527 is a transverse mounting plate structure provided with an inclined support, and is used to mount the second monitoring instrument 512;

[0039] The second monitoring instrument 512 is an external monitoring instrument, such as a wind speed monitoring instrument.

[0040] The advantages of the tower monitoring system using an integrated tower installation mechanism are as follows: the integrated installation mechanism can be used for the installation of towers of different diameters, and can be used on similar cylindrical structures of existing structures or structures under construction; there are two types of instrument installation mechanisms designed for the installation of multiple monitoring instruments, which can simultaneously perform all-round monitoring of the tower, which is conducive to data acquisition and comprehensive analysis; installation and removal and maintenance are more convenient and efficient; after the integrated installation mechanism is installed, flexible switching between monitoring and operation and maintenance can be achieved, and there is no need to disassemble the main body of the integrated installation mechanism again. It only needs to replace the installed monitoring instruments according to requirements, ensuring that both monitoring and maintenance have minimal impact on the transmission tower and increasing its service life.

[0041] The installation method of the tower integrated installation mechanism on the pile tower is as follows Figure 6 As shown, during installation, the installation positions of the first hoop member and the second hoop member need to be determined according to monitoring requirements, and a distance needs to be left between them; tighten the two ends of the hoop through the fastening member using a tightening device, and then install the vertical mounting rod on the bolt reserved openings of the first hoop member and the second hoop member through bolts, connecting the entire member into a whole, enhancing the firmness of the tower pole integrated monitoring installation member, and ensuring that it can withstand various environmental effects.

[0042] Since the multi-source stereo monitoring system is in an unmanned outdoor environment for a long time, it is particularly important to ensure the stability of data transmission. The GPRS data transmission part uses the industrial-grade dual-band module MC52i, which has a built-in TCP / IP protocol stack. The program flow of the GPRS data transmission module is as follows Figure 4 As shown in the figure, the microcontroller can send AT commands through the serial port to control the operation of GPRS. After power-on initialization, it is necessary to establish a GPRS connection with the host computer, and then transmit GPRS data packets in the set format. Each time the module executes an instruction, it will return a small response message and result code to the microcontroller, so that the microcontroller can control the entire data transmission process through the current execution status. Secondly, in order to improve its stability, it is necessary to use ESD chips to improve the electrostatic protection ability of the system, and add TVS diodes to key circuits to deal with lightning strikes and surge voltages; on the other hand, it is necessary to shorten the routing length of sensitive circuits and lay ground for them.

[0043] The data management and analysis system is used to store, manage and analyze the monitoring data collected by the multi-source stereo monitoring system. It uses Apache server, XBOP application server and PostgreSQL database to realize real-time monitoring of transmission tower data and provide historical monitoring data query in the form of form, which provides convenience for researchers to analyze related issues. Taking the ground temperature monitoring of the tower foundation in the frozen soil area as an example, after the temperature measurement and deformation monitoring instruments are buried, the server is required to store and manage the relevant data of air temperature, ground temperature and deformation in a complete freeze-thaw cycle, and then analyze the temperature depth curve and deformation curve at different times and the deformation with temperature curve, and finally analyze the relationship and interaction mechanism of air temperature-ground temperature-deformation, so as to make a preliminary analysis and evaluation of the stability of the tower foundation.

[0044] The interface display system displays the monitoring results of the multi-source stereo monitoring system through a mobile device with a mobile processor. The system is implemented through the Interactive Data Display software package, which can complete the connection with the data management and analysis system, and realize the import, export, classification, search and display functions of instrument information and related data. The mobile terminal can display the monitoring data display and management module, the on-site real-time monitoring module and the monitoring alarm module.

[0045] like Figure 5 As shown, the interface display system 3 includes a monitoring data display and management module 31, a field real-time monitoring module 32 and a monitoring alarm module 33, wherein:

[0046] The monitoring data display and management module 31 is used to display the real-time monitoring data of the monitoring instruments installed on the tower base and the tower pole, including the stress, settlement, ground temperature, groundwater, foundation deformation and other data at the tower base, the inclination of the tower pole, and the wind speed, rainfall, node displacement, local cracks, temperature and other data around the tower pole, and can select relevant data parameters within a period of time to intuitively display the change law of the monitoring data in the form of images or tables. All data collected by the monitoring instrument during the monitoring time period will be automatically imported through the database, and the update status of the data file will be fed back at the front end. It can also summarize the data missing or erroneous entries of the imported file, and import the historical observation data corresponding to each transmission tower in a fixed format, and support the creation and import of other real-time monitoring data;

[0047] The on-site real-time monitoring module 32 is used to provide real-time collection of transmission tower scene images, including a personnel safety monitoring module and an equipment safety monitoring module. The personnel safety monitoring module includes an attendance recording unit and a personnel information unit, wherein: the attendance recording unit is used to perform facial recognition and recording of on-site construction personnel through a monitor to monitor the workers; the personnel information unit is used to remind construction personnel to wear smart safety helmets. The safety helmets are equipped with locators, which remind workers to wear safety helmets by making real-time comparisons with the positioning information of the attendance recording unit. The equipment safety monitoring module is used to record the operating status information of the transmission tower maintenance and transportation equipment.

[0048] The monitoring alarm module 33 is used for alarming risk points during tower base monitoring and operation and maintenance management, including a transmission tower abnormal data alarm module and an operation and maintenance construction safety alarm module. The transmission tower abnormal data alarm module is used to control the alarm system to issue an early warning when the monitoring data of the transmission tower is abnormal and exceeds the set control value. The operation and maintenance construction safety alarm module mainly records illegal acts that violate the safety management regulations of the construction site and issues an early warning to remind maintenance personnel.

[0049] To sum up, the data-driven multi-source stereoscopic monitoring and intelligent operation and maintenance digital management system for transmission and transformation tower bases provided by the present invention can realize the integrated control of tower base stability monitoring and operation and maintenance management, improve the working efficiency of monitoring equipment, enhance the efficiency of operation and maintenance management, improve the automation, intelligence and digitization level of transmission line tower monitoring, reduce maintenance risks, and reduce the maintenance cost of monitoring equipment.
