Description

A kind of portable chemical test device
Technical field
The present invention relates to a kind of chemical substance detection means, especially portable chemical substance monitoring device.
Background technology
In the last few years, people also became more and more higher to the miniaturization of control system and intelligentized requirement, and then increasing chemical substance collection and control system are adopted 51 Core of the single-chip microcomputer as chemical substance control system.Generally adopt with PC Used as main frame, control program of the single-chip microcomputer as slave, wherein single-chip microcomputer have been used for the collection and the control to device of paired data, and data processing and the control to single-chip microcomputer are then completed by main frame.
With the progress of science and technology, embedded technology is more and more ripe, and people are also more and more ripe to the application process of novel embedded system equipment miscellaneous, wherein ARM The mainstream technology of embedded aspect, it be widely used in information household appliances, traffic administration, home intelligent management system, POS The field such as network and ecommerce, Industry Control.With PC Compare ARM System have with compactness and portability and the characteristics of high specificity, it is more convenient in operation and use, so selecting to use ARM Host computer of the processor as control system, it is single-chip microcomputer to constitute by slave computer, and host computer is ARM Water tank chemical substance monitoring system.
Due to ARM Itself has the ability of man-machine interaction, compared with simple use 51 The chemical substance detecting system of single-chip microcomputer, the system are even more on the characteristics of taking into account compactness and easy to operate and are provided with good interactive capability.
The content of the invention
It is an object of the invention to design a kind of portable chemical substance detection means, it is to avoid with PC Used as main frame deficiency inconvenient to carry, the present invention can not only show real time data to machine, and can show the performance graph of chemical substance change.
The object of the present invention is achieved like this:
A kind of portable chemical test device, including chemistry sensor, sensor corrosion monitoring circuit, processor and display composition, it is characterised in that:The processor includes STC12C5410AD Single-chip microcomputer, serial port device, ARM Module;The chemistry sensor connects sensor corrosion monitoring circuit, and the sensor corrosion monitoring circuit passes through A/D Interface connects STC12C5410AD Single-chip microcomputer, it is described STC12C5410AD Single-chip microcomputer is connected by serial port ARM Module, it is described ARM Module connects display;
It is described ARM The communication mode of module is RS232 Serial communication; ARM Module passes through power conversion chip MAX232 Carry out level conversion, ARM Module and the same power supply of one-chip machine common are powered.
The single-chip microcomputer RXD(P3.0) With MAX232 's R1OUT It is connected, TXD(P3.1) With MAX232 's T1IN It is connected.
The operation principle of the present invention:The present invention collects data by chemistry sensor, by the extent of corrosion of sensor corrosion monitoring circuit monitoring sensor, convenient to remind with emat sensor device;Chemistry sensor is collected data and is transferred to processor, processor after disposal data by data display over the display.
The construction featuress and beneficial effect of the present invention:The present invention is suitable for the chemical substance detection of various environment with easy to carry, simple to operate;Single-chip microcomputer with ARM Between adopt serial communication protocol, it is ensured that the Stability and veracity of chemical substance signal transmission.
