A remote data transmission device and method for underground water level and water temperature

Abstract

The invention provides a device and method for transmitting remote data of the water temperature of a ground water level. The device comprises field monitoring equipment, a communication interface module, a microprocessor, a transmission module, a clock module and a power unit, wherein the clock module is used for providing a clock benchmark for the device, and the power unit is used for providing power for all the working units. The power unit comprises a power supply, a normally-opened power module, an interruptable power module and a battery monitoring module unit. The power supply directly provides power for the transmission module and is connected to the normally-opened power module and the interruptable power module respectively after two times of voltage stabilization. The normally-opened power supply provides working voltage for a microcontroller, a real-time clock, a communication interface and a battery monitoring unit. The interruptable power module provides working voltage for a water level monitor, a water temperature monitor and an air pressure sensor. The battery monitoring module unit is used for monitoring the working state of the interruptable power module. The device not only can carry out real-time monitoring and remote control on the running conditions of the monitoring instrument, but also can ensure that the power supply is switched off in a non-work state to reduce power consumption to the largest degree.

Description

technical field [0001] The invention belongs to the technical field of geological environment parameter monitoring, and in particular designs a device and method capable of real-time and remote transmission of groundwater level and temperature data. Background technique [0002] Groundwater is an important part of water resources. Groundwater plays an extremely important role in ensuring the safety of drinking water for the people, promoting economic and social development, and maintaining ecological balance. Geological disasters and ecological environmental problems such as groundwater level decline, land subsidence, karst subsidence, seawater intrusion, and land degradation have become important constraints to comprehensive, coordinated, and sustainable economic and social development. Most of the existing monitoring points are still based on manual measurement, with a low degree of automation and poor monitoring accuracy, which is far from meeting the requirements of moni...

AI Technical Summary

Problems solved by technology

Most of the existing monitoring points are still based on manual measurement, the degree of automation is low, and the monitoring accuracy is poor, which is far from meeting the requirements of monitoring the development and utilization of groundwater and the dynamic evaluation of groundwater

Although automatic monitors are installed in a few areas, they generally work in the way of regular on-site extraction. Real-time monitoring of the operating status of the monitoring instruments (working status, battery status, data storage, etc.) cannot be carried out. If there is a fault, it can only be discovered and eliminated when professional monitoring personnel take data, which will cause the loss of monitoring data and seriously affect the integrity and quality of groundwater monitoring

In addition, when the monitoring frequency needs to be adjusted in time due to emergencies, the existing equipment requires staff to go to the field to make adjustments, and the emergency response capability is poor.

There is a gap between the existing domestic monitoring instruments and foreign developed countries, mainly in the long-term stability of the instruments and high power consumption; the production process is not standardized, and the quality is difficult to control in mass production
