Abstract

The utility model discloses a various-gas detecting system for a singlechip. The system comprises a gas sensor array, an A/D converter connected with the gas sensor array, a singlechip connected with the A/D converter, an LED display screen connected with the singlechip, and an alertor, wherein an alcohol sensor, a methane sensor and a carbon monoxide sensor are arranged on the gas sensor array; the sensor array comprising a plurality of sensors can gather the information of a certain gas; and the gas type and the gas concentration can be displayed through information conversion and digital processing, thereby providing a practical solution for detecting information.

Description

A kind of single-chip microcomputer multiple gases detection system

Technical field

The utility model relates to a kind of single-chip microcomputer multiple gases detection system.

Background technology

Traditional gas detects and mostly adopts single gas detection mode, and namely measuring a kind of gas needs a kind of measurement instrument, during use, very inconvenient.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of instrument can carry out multiple gas detection and Identification.

The utility model is achieved through the following technical solutions: a kind of single-chip microcomputer multiple gases detection system, comprise gas sensor array, and the A/D converter that links to each other with gas sensor array, and the single-chip microcomputer that links to each other with A/D converter, and the LED display and the alarm that link to each other with single-chip microcomputer, described gas sensor display is provided with alcohol sensor, methane transducer, carbon monoxide transducer.

As preferred technical scheme, four of the display packing of described LED display employings dynamically show, the first gas, rear three the demonstration gas concentrations of showing.

As preferred technical scheme, described single-chip microcomputer is low-power consumption, the high-performance 8-bit microcontroller by the 80C51 compatibility of the companies such as ATMEL, PHILIPS and SST production.

A kind of single-chip microcomputer multiple gases detection system of the present utility model, the sensor display that adopts multisensor to form, can carry out information acquisition for certain gas, transform and the data processing by information, can show gaseous species and gas concentration information, for the detection of much information provides a kind of practicable solution.

Description of drawings

In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.

Fig. 1 is the schematic diagram of this practical a kind of single-chip microcomputer multiple gases detection system.

Embodiment

As shown in Figure 1, a kind of single-chip microcomputer multiple gases detection system, comprise gas sensor array 1, and the A/D converter 2 that links to each other with gas sensor array 1, and the single-chip microcomputer 3 that links to each other with A/D converter 2, and the LED display 4 and the alarm 5 that link to each other with single-chip microcomputer 3, described gas sensor display 1 is provided with alcohol sensor (not shown), methane transducer (not shown), carbon monoxide transducer (not shown); During work, gas sensor display 1 detects various gases, single-chip microcomputer 3 image data are processed, digital model by various gas concentrations calculates its concentration, A/D converter 2 is digital signal with the analog signal conversion of output, LED display 4 shows its corresponding gaseous species and concentration value, and when concentration over-standard, alarm 5 is reported to the police.

Wherein, the display packing of described LED display 4 adopts four dynamically to show, the first gas that shows, and rear three show gas concentration; Described single-chip microcomputer 3 is low-power consumption, the high-performance 8-bit microcontrollers 3 by the 80C51 compatibility of the companies such as ATMEL, PHILIPS and SST production.

Above-described embodiment; it is an example of the present utility model; be not to limit enforcement of the present utility model and scope of authority, all or technical schemes of being equal to identical with the described content of the utility model claim all should be included in the utility model protection domain.
