Description

Water turbidity analyser based on the MSP430 single-chip microcomputer

Technical field

The utility model relates to a kind of portable water quality turbidity analyser, is specifically related to a kind of analyser for on-the-spot Quantitative detection water turbidity.

Background technology

Turbidity analyser is widely used in the fields such as food, oil, chemical industry, environmental monitoring, medical and health, in commercial production, need to constantly monitor the indices of liquid in the production process, and wherein the measurement of turbidity is in occupation of very important position; Because the turbidity of water quality height also needs to use turbidity analyser on the healthy impact of human body also very large in the water body in river, lake detects.

Several water turbidity analytical instrument of available technology adopting often exist volume large, be not easy to carry, brought certain difficulty to field exploration; Simultaneously in the process of measuring, very numerous and diverse of the processing of data is so that the power consumption of whole device is high.

The utility model content

For above-mentioned deficiency of the prior art, the utility model has offered a kind of water turbidity analyser with advantages such as little, the low in energy consumption and circuit of volume are simple.

In order to reach the foregoing invention purpose, the utility model provides a kind of water turbidity analyser based on the MSP430 single-chip microcomputer, the control circuit that it comprises housing and is arranged on enclosure interior, described control circuit comprises power module, metering circuit, signal conditioning circuit, processor, load module and display module, described metering circuit, signal conditioning circuit, processor, load module and display module are connected with power module and are connected, described signal conditioning circuit is connected with processor with metering circuit respectively, and described load module is connected with processor with display module and is connected.

Preferably, described processor adopting is the MSP430 single-chip microcomputer.

Preferably, described metering circuit comprises optical generator and optical receiver, and described optical receiver is connected with signal conditioning circuit.

Preferably, described display module comprises LCDs and LED light.

Preferably, described power module comprises linear stabilized power supply chip and switching capacity back-pressure chip.

Preferably, also be provided with the USB power supply interface on the described power module.

Preferably, be provided with at least on the described housing measurement, on turn over and under turn over three buttons.

Preferably, described housing is that waterproof plastic is made.

In sum, the beneficial effects of the utility model are: what should adopt based on the water turbidity analyser of MSP430 single-chip microcomputer is the transmission principle, optical receiver converts the reflection source that receives to electric signal and sends to signal conditioning circuit, signal conditioning circuit is transferred to processor after electric signal is changed into the signal that processor can identify, when storing signal, processor by display screen data measured is shown, the liquid turbidity accuracy that measures is high, it also has the advantages such as circuit is simple, low in energy consumption, volume is little.

Description of drawings

Fig. 1 is the theory diagram based on the water turbidity analyser of MSP430 single-chip microcomputer.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further:

As shown in Figure 1, should be based on the water turbidity analyser of MSP430 single-chip microcomputer, the control circuit that it comprises housing and is arranged on enclosure interior, described control circuit comprises power module, metering circuit, signal conditioning circuit, processor, load module and display module, described metering circuit, signal conditioning circuit, processor, load module and display module are connected with power module and are connected, described signal conditioning circuit is connected with processor with metering circuit respectively, and described load module is connected with processor with display module and is connected.

Described processor adopting be the MSP430 single-chip microcomputer; Described metering circuit comprises optical generator and optical receiver, and described optical receiver is connected with signal conditioning circuit; Described display module comprises LCDs and LED light; Described power module comprises linear stabilized power supply chip and switching capacity back-pressure chip; Also be provided with the USB power supply interface on the described power module; At least be provided with on the described housing measurement, on turn over and under turn over three buttons; Described housing is that waterproof plastic is made.
