Description

Technical Field

[0001] The utility model relates to the technical field of mining disaster monitoring, in particular to a horizontal displacement measuring device for mining-induced ground fissures. Background Art

[0002] Ground fissures are discontinuities or faults in the rock and soil media that develop in the Earth's crust. They are manifestations of surface ruptures caused by internal and external forces, as well as human activities. With the intensification of human engineering activities and excessive groundwater and oil extraction, ground fissures have appeared in many regions around the world, including China, the United States, Mexico, Australia, and in Africa, such as Kenya and Ethiopia. In North my country, particularly the Fenwei Basin, intense neotectonic activity has led to the continuous development of ground fissures in over 50 counties and cities since the mid-to-late 20th century, resulting in severe damage, the highest in China. As a unique geological hazard, ground fissures not only directly damage various engineering structures, such as urban buildings, lifeline projects, transportation, farmland, and water conservancy facilities, but also cause a series of environmental problems. Therefore, it is necessary to monitor the horizontal displacement of ground fissures to accurately assess their status.

[0003] A device for measuring the horizontal displacement of mining-induced ground fissures based on a UWB wireless ranging sensor is suitable for complex and harsh outdoor environments. It can monitor the horizontal displacement of ground fissures in real time and issue an early warning when necessary, simplifying the measurement steps, improving measurement accuracy, and reducing the danger of manual field measurements. Summary of the Invention

[0004] In view of the defects or shortcomings in the existing technology, the utility model provides a horizontal displacement measurement device for mining-induced ground fissures based on UWB wireless ranging sensors to solve the real-time measurement and early warning of mining-induced ground fissures in complex field environments.

[0005] The utility model solves the above technical problems through the following technical solutions: a device for measuring the horizontal displacement of mining-induced ground fissures based on a UWB wireless ranging sensor, comprising a UWB base station, a UWB tag, a data receiving controller, a power supply group and a computer. The UWB base station is installed on a base station bracket, two solar panels are installed on the top of the base station bracket, and two rechargeable batteries are reserved under each of the solar panels.

[0006] As a further implementation method, the power supply of the UWB base station is provided by both solar panels and batteries. The UWB base station will give priority to using solar panels for power supply. At night and when there is insufficient sunlight, the UWB base station will use batteries for power supply. While ensuring that the UWB base station has sufficient power, part of the electricity generated by the solar panels will also charge the battery.

[0007] As a further implementation method, the UWB tag housing is made of aluminum alloy, the connection parts are coated with waterproof glue, and strip-shaped and circular fixing holes are reserved on both sides of the UWB tag housing.

[0008] As a further implementation method, the computer is connected to a data receiving controller and is used to display, store and process the signals transmitted back by the UWB base station. At the same time, it can display an image of the horizontal displacement of the ground fissure changing over time. The computer can set a warning value for the horizontal displacement of the ground fissure and display an alarm message when the horizontal displacement of the ground fissure reaches the warning value.

[0009] The beneficial effects of the utility model are as follows: the utility model is mainly used for real-time monitoring of the horizontal displacement of ground fissures. It can monitor the horizontal displacement of ground fissures in real time under low power consumption and complex and harsh environmental conditions, and issue early warnings when necessary, thereby simplifying the measurement steps, improving the measurement accuracy, and reducing the danger of manual field measurement.
