Apparatus for multi-dimensional measurement of heavy metal content

Abstract

The invention discloses an apparatus for multi-dimensional measurement of heavy metal content, which comprises a cloud platform information processing end, a multi-depth sample collecting apparatus, an Android mobile phone control end, a microprocessor main control module, a power supply module, and an electrochemical sensor module. The cloud platform information processing end receives data sentby the Android mobile phone end to realize a cloud storage function. The multi-depth sample collecting apparatus comprises five parts such as an internal sample testing area and an outer side samplingaccess port. The Android mobile phone control end adopts the form of a two-stage interface, which is a Wi-Fi selection interface and a motor control and display interface. The microprocessor main control module adopts an STM32F407 chip and is powerful in function. The power supply module adopts a lithium battery, which is small in size and is green and environment friendly. The electrochemical sensor module is attached with a three-electrode test module, a constant potential module, and a circuit self-check and active shielding module. According to the apparatus for multi-dimensional measurement of heavy metal content, the multi-depth detection can be achieved on the content of heavy metal ions in rivers and lakes, information can be fed back to a cloud platform in time, so that the purposes of information processing and storage are realized, and the apparatus is suitable for popularization and use.

Description

technical field [0001] The invention relates to a device for measuring heavy metal content in multiple dimensions, which belongs to the field of heavy metal detection and intelligent control. Background technique [0002] At present, heavy metal pollution in water has become a growing topic. Heavy metal wastewater from mining, machinery manufacturing, chemical industry, electronics, instrumentation and other industrial production processes generally includes heavy metal ions such as chromium, cadmium, copper, mercury, nickel, zinc, etc. Agricultural activities such as farming that require lake water cause pollution. Especially in aquaculture production, different fish live in different water depth environments, and timely reflection of the heavy metal content in water at each depth provides a reference for their aquaculture input. Facts have proved that the content of heavy metal ions in different water depths will be different due to geological elements, pollution dischar...
