Karst collapse water vapor pressure remote monitoring system

Abstract

The invention discloses a karst collapse water vapor pressure remote monitoring system. The system comprises an observation well, a sensor monitoring module, a solar energy power supply module, a data acquisition and transmission module and a client. The sensor monitoring module comprises a hole water pressure sensor and a gas pressure sensor. The solar energy power supply module comprises a solar panel, a solar cell controller and a storage battery. The data acquisition and transmission module comprises a microcomputer time control switch, a GPRS wireless communication module and a data acquisition instrument. The client allows a user to check real-time data and historical data in an online mode and allows the user to remotely set a karst water vapor power monitoring density according to a need. By using the karst water vapor power monitoring system and the method, changes of water vapor pressure in a karst cavity can be continuously, stably and remotely monitored in a long-term mode, a karst collapse geological disaster mechanism is researched and purposes of karst collapse monitoring and early warning are reached.

Description

technical field [0001] The invention relates to a remote monitoring system for karst subsidence geological disasters, in particular to a remote real-time monitoring system for water vapor pressure in karst subsidence. Background technique [0002] Karst collapse is a common geological disaster in karst areas. Occurs from time to time both abroad and in our country, bringing serious impact on national economic construction and the lives of the people. One of the main influencing factors of karst subsidence is the change of ground water vapor pressure in the karst area. At present, the monitoring of the influencing factors of karst subsidence is mainly the monitoring of groundwater level. The monitoring cycle is once an hour, and the real-time performance is poor. It is difficult to capture the change of karst groundwater pressure. However, it is very important to obtain real-time changes of groundwater pressure in karst areas. [0003] At present, there are many groundwater...

AI Technical Summary

Problems solved by technology

At present, the monitoring of factors affecting karst subsidence is mainly the monitoring of groundwater level. The monitoring cycle is once an hour, and the real-time performance is poor. It is difficult to capture the change of karst groundwater gas pressure. It is very important to obtain real-time changes in karst groundwater gas pressure.

[0003] At present, there are many groundwater dynamic monitoring systems, but most of them only realize the dynamic monitoring of the groundwater level. The monitoring cycle is once a day, which cannot be monitored in real time, and it is difficult to meet the collection density of monitoring data.

[0004] Existing patent documents are only aimed at the monitoring of groundwater level, water temperature, PH value, etc., without considering the special geological conditions in karst subsidence areas and the demand for gas pressure monitoring, and at the same time, the monitoring density cannot be changed remotely as needed
