A method of saving electricity for a groundwater level monitoring system in the field

Abstract

The invention relates to an electricity-saving method for a field underground water level monitoring system. The electricity-saving method includes the steps that the monitoring system is set to be four different working models according to a cumulative amount of change of underground water levels in each time period, when the cumulative amount of change of the underground water levels is greater than an alarm value, the monitoring system enters a common model, and parts in the system are all opened; when the cumulative amount of change of the underground water levels is located between a critical alarm value and the alarm value, the monitoring system enters an off-line model, and only a communication module is closed; when the cumulative amount of change of the underground water levels is located between a dormancy value and the critical alarm value, the monitoring system enters a standby model, and only a central processing unit (CPU) and the communication module are opened; when the cumulative amount of change of the underground water levels is smaller than the dormancy value, the monitoring system enters a dormancy model, and only a clock and an activating circuit are opened. The electricity-saving method for the field underground water level monitoring system has the advantages that the underground water levels can be automatically monitored and can be transmitted to a remote server in a wireless mode, and a user can visit the remote server through a remote system management platform and looks up monitoring data. In addition, the monitoring system can be automatically switched to the corresponding working models so as to achieve the purpose of saving electricity, the use time of a device can be prolonged, and waste of labor and material resources for replacement of batteries can be saved.

Description

technical field [0001] The invention belongs to the field of automatic water level monitoring, and in particular relates to a power saving method used in an underground water level monitoring system in the field. Background technique [0002] Since groundwater is an important aspect that affects the living environment of human beings, people pay more and more attention to the monitoring of various data of groundwater. In order to comprehensively monitor the changes in the groundwater level of a city, it is necessary to select several typical groundwater level observation points within the scope of the city according to the geological structure of the city, and then set up one or several observation points at each observation point. Groundwater level observation wells are used to measure the data of groundwater levels in different formations. [0003] The traditional method of monitoring the groundwater level is realized by manual measurement and collection. Due to the great...

However, since the observation wells are all set outdoors or even in the field, the monitoring instrument cannot be powered by the power supply line, and the monitoring instrument must be powered by a battery. For about 42 days, monitoring instruments need to be maintained every one and a half months, which means that for a city with hundreds of observation wells, the workload of monitoring personnel will still be huge

[0005] In order to achieve a longer service life of the monitoring instrument, some monitoring units have installed a solar power supply device on the monitoring instrument to achieve sustainable power supply. High, and the solar power supply device is exposed to the ground and is easy to be stolen, so it is not suitable for large-scale application

Some monitoring units also achieve the purpose of saving power by reducing the daily monitoring frequency of monitoring instruments, such as monitoring twice a day. The disadvantage of this power-saving method is that the frequency of monitoring is simply limited, and it cannot adapt to large changes in groundwater levels such as rainy seasons. Therefore, it is impossible to provide monitoring units with real-time and effective monitoring data to take effective countermeasures
