Ultrasonic liquid level recorder based on automatic document management system and GSM module

Abstract

The invention provides an ultrasonic liquid level recorder based on an automatic document management system and a GSM module. On the basis of a high-precision ultrasonic distance measuring module, a high-speed microprocessor, a document management chip, a high-speed NANDFlash storage chip, a GPS positioning module, a solar cell panel, a GSM communication module and a lithium battery charging and discharging management module are embedded in the recorder used for unattended liquid level data collecting in a super-long period in the field. The recorder can be conveniently placed on any position in the field, and is immediately in a liquid level collecting state when powered up. The ultrasonic distance measuring module sends liquid level data to the microprocessor at the sampling rate of 1 hertz per second in real time. Meanwhile, the document management chip is started so as to write the real-time liquid level data into the high-speed Flash storage chip. According to GPS timing time, a liquid level event document is automatically generated. Besides, the data can be sent to a specific mobile phone through the GSM module. The recorder can be widely used in a plurality of fields such as scientific investigation and industrial and agricultural production, and is low in cost, high in reliability, wide in application range and easy to popularize.

Description

technical field [0001] The invention relates to the technical field of liquid level monitoring, and is especially applied to field ultra-long-period liquid level collection or unattended liquid level collection in a specific area in many fields such as scientific investigation and industrial and agricultural production. Background technique [0002] At present, the field ultra-long-period liquid level acquisition records or unattended liquid level acquisition devices in specific areas used in many fields such as scientific investigation and industrial and agricultural production are relatively simple, and there are three main shortcomings. [0003] 1. The power supply part usually uses a single large-capacity battery to power the equipment. However, due to the long-term harsh natural environment in the field, the existing devices often have power supply batteries corroded and failed, and the acquisition system has system voltage instability due to rain and snow and other adv...
