Portable water quality monitor for sewage treatment

Abstract

The invention provides a portable water quality monitor for sewage treatment. The portable water quality monitor comprises an upper computer and a lower computer, wherein the upper computer and the lower computer are connected with each other through communication middleware or a wireless communication part, and the upper computer comprises an upper computer man-machine interface part; the lower computer comprises a single chip microcomputer, a data acquisition part, an extended SDRAM part and a lower computer man-machine interface part, the data acquisition part is provided with SDI-12 sensorconnected with the single chip microcomputer through a telescoping SDI-12 interface bus, and the SDI-12 interface bus is connected with at least one SDI-12 sensor through a joint-joint type interface; the wireless communication part includes a GPRS wireless module; and power supply part includes a self-contained power supply, a solar power supply and a power supply management module which switches the power supply to the self-contained power supply when voltage supplied by the solar power supply is insufficient to maintain the operation of the water quality monitor. The number of sensors connected to the portable water quality monitor for sewage treatment is unrestricted, the data transmission is simple, and the data storage amount is large.

Description

technical field [0001] The invention relates to the field of environmental monitoring, and relates to a water quality monitor, in particular to a portable sewage treatment water quality monitor. Background technique [0002] Water is a natural resource that human beings rely on for survival. With the continuous aggravation of environmental pollution, people have put forward higher requirements for on-site monitoring technology of water quality. Water quality monitoring instruments are mainly used to monitor various parameters such as water conductivity, temperature, PH value, and dissolved oxygen. The current common method is on-site sampling and laboratory analysis, which is costly and cannot guarantee real-time monitoring. sex and reliability. With the development of my country's environmental protection work, although the technology of water quality monitoring has made great progress, there are still some shortcomings: (1) when the existing water quality monitors process...

Problems solved by technology

With the development of my country's environmental protection work, although the technology of water quality monitoring has made great progress, there are still some shortcomings: (1) when the existing water quality monitors process multi-sensor signals, they generally use multiple channels Analog switches are used to select the parameters to be measured, which limits the number of connected sensors, thereby limiting the number of water quality parameters collected (; 2) When there are data collected by multiple sensors, the existing The realization of data transmission between the water quality monitoring instrument and the PC is more complicated. At this time, each port needs to be set separately, and it is easy to cause instability of the program and data transmission (; 3) The existing water quality monitoring instrument has a small data storage capacity , and generally without the support of the operating system, the ability to process tasks in parallel with multi-threading and multi-tasking is not strong, and it is also not conducive to the expansion of functions
