Description

TECHNICAL FIELD

[0002] The tower erecting and dismantling system refers to a series of equipment and methods used for the lifting, dismantling and assembly of towers. This system plays a crucial role in power line construction, maintenance and wireless communication base station construction.

[0003] In the traditional technology of the tower erecting and dismantling system, there is indeed no widely combined multi-sensor device. The existing technology in this field mainly relies on single sensors or simple sensor combinations for monitoring the basic state of the tower during the erecting and dismantling process, such as tension, tension or inclination angle, etc. However, these traditional methods have many limitations and deficiencies. On the one hand, traditional sensor devices are often single-function, only capable of monitoring a certain aspect of the tower. For example, some devices may only be used to measure the inclination angle of the tower, and cannot simultaneously monitor key parameters such as tension or tension. This results in the inability of operation and maintenance personnel to obtain comprehensive data support during the tower erecting and dismantling process, making it difficult to accurately assess the overall state of the tower. On the other hand, multiple single-function sensors require a lot of time and effort to group sensors and data interface monitoring platforms during deployment and use.

[0021] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0022] In one embodiment, as shown in FIG. 1, a sensor device in a tower erecting and dismantling system is provided, which includes an integrated sensor assembly 100 for weather sensing and inclination sensing, a portal frame lifting sensor assembly 200, a portal frame cable sensor assembly 300, a portal frame metering sensor assembly 400, an electrical-optical switching assembly 500, and an electrical switching assembly 600. Figure 1 The integrated sensor assembly 100, the portal frame lifting sensor assembly 200, and the portal frame cable sensor assembly 300 are connected with the electrical-optical switching assembly 500 respectively; the portal frame metering sensor assembly 400 is connected with the electrical switching assembly 600; and the electrical-optical switching assembly 500 is connected with the electrical switching assembly 600.

[0023]

[0024] ​The integrated sensor assembly 100 is mainly used for meteorological sensing and inclination sensing. The meteorological sensing part can monitor environmental temperature, humidity, wind speed and other meteorological parameters to provide meteorological data support for tower erection and dismantling. The inclination sensing part is used to monitor the inclination angle of the tower or related components to ensure structural stability. The integrated sensor assembly 100 can specifically include multiple functionally similar sub-assemblies that can be arranged at different height positions of the tower to accurately collect multiple parameters during the erection and dismantling process of the tower.

[0025] The gantry lifting sensor assembly 200 is used to monitor key parameters such as load and lifting height during the gantry lifting process. Specifically, load sensors and height sensors can be installed on the lifting mechanism of the gantry. The load sensor is used to monitor the load change in real time during the lifting process, and the height sensor is used to record the lifting height. These sensors are connected to the electrical and optical exchange assembly 500 through wired connection to realize real-time data transmission.

[0026] The gantry cable sensor assembly 300 is used to monitor the tension change of the gantry cable to ensure the safety and stability of the cable during the lifting process. Specifically, tension sensors can be installed on the cable of the gantry and connected to the electrical and optical exchange assembly 500 through wired or wireless means. The tension sensor can monitor the tension change of the cable in real time and transmit the data to the electrical and optical exchange assembly 500 for processing.

[0027] The gantry meter sensor assembly 400 is used to record the distance during the movement or lifting of the gantry to provide accurate displacement data for tower erection and dismantling. Specifically, meter sensors can be installed on the moving mechanism of the gantry and connected to the electrical exchange assembly 600 through wired connection. The meter sensor can accurately record the movement distance of the gantry and transmit the data to the electrical exchange assembly 600 for storage and analysis.

[0028] The electric-optical exchange assembly 500 serves as a relay station for data transmission, which aggregates and converts the data from the integrated sensor assembly 100, the gantry lifting sensor assembly 200, and the gantry cable sensor assembly 300, and then transmits them to the electric exchange assembly 600. The electric-optical exchange assembly 500 uses high-speed data transmission technology, such as optical fiber communication or high-speed Ethernet technology, to ensure the real-time and accuracy of the data. It receives data from various sensor assemblies, performs necessary format conversion and encryption processing, and then transmits them to the electric exchange assembly 600. Further, the electric-optical exchange assembly 500 includes a 2E8O switch. The 2E8O switch has two electrical ports and eight optical ports, which can meet various data transmission requirements simultaneously. In the tower erection and dismantling system, the sensor device needs to transmit a large amount of data, and the data types are diverse, so the 2E8O switch can provide sufficient interfaces and bandwidth to support data transmission. Optical fiber communication has the advantages of fast transmission speed and strong anti-interference ability. In the tower erection and dismantling system, the real-time and accuracy of data transmission are required, so the use of optical fiber communication can ensure the timely transmission and accuracy of data. The 2E8O switch has a compact structure, which is easy to install and maintain. In the tower erection and dismantling system, the space is limited, so choosing a compact device can save space and facilitate installation and maintenance.

[0029] The electric exchange assembly 600 serves as a second relay station for data transmission, which aggregates the data collected by the gantry metering sensor assembly 400 and receives the data sent from the electric-optical exchange assembly 500. Specifically, the electric exchange assembly 600 includes a 16E switch. The 16E switch provides 16 electrical ports, which can meet the needs of multiple sensor devices connecting and data transmission simultaneously. In the tower erection and dismantling system, multiple parameters may need to be monitored simultaneously, so choosing a switch with a large number of ports can ensure the comprehensive transmission of data. The 16E switch has high data transmission capacity and can support concurrent transmission of a large amount of data. In the tower erection and dismantling system, the sensor device may collect a large amount of data, so choosing a switch with strong data transmission capacity can ensure the timely transmission and processing of data. The 16E switch usually has good scalability, which can increase the number of ports or upgrade the performance of the device according to actual needs. In the tower erection and dismantling system, as the number of sensor devices increases or the demand for data transmission increases, the performance of the switch may need to be expanded or the number of ports may need to be increased, so choosing a switch with strong scalability can adapt to future changes in demand.

The entire system can collect various sensor data, including weather, tilt, gantry tension, cable tension, and cable length, achieving diversified sensing functions. Furthermore, the different sensor components respectively achieve data collection and output through the electro-optical exchange assembly 500 and the electrical exchange assembly 600, ensuring reliable sensor data output.

The second voltage converter is used to convert the input power voltage into the working voltage required by the second integrated sensor assembly. The third voltage converter is used to convert the input power voltage into the working voltage required by the third integrated sensor assembly.
