Abstract
The utility model discloses a computer control-based natural gas alarm device for civil residences, relates to the computer field, and specifically relates to the computer control-based natural gas alarm device for the civil residences. The problem that at present natural gas leakage cannot be found timely can be solved by the device. A sampled signal output terminal of a smell sensor is connected to a pending signal input terminal of a data processing circuit, a sensor signal processing output terminal of the data processing circuit is connected to an analog quantity signal input terminal of an A/D converter, and a digital quantity signal output terminal of the A/D converter is connected to a sampled signal input terminal of a main single-chip microcomputer; and two control signal output terminals of the main single-chip microcomputer are respectively connected to control signal input terminals of an alarm and a valve shutting-off control circuit, and a control signal output terminal of a keyboard is connected to a control signal input terminal of the main single-chip microcomputer. The computer control-based natural gas alarm device is used in the civil residences.
Description
Technical field
The utility model relates to computer realm, is specifically related to a kind of based on computer-controlled residential houses natural gas warning device.
Background technology
Residential houses generally adopts rock gas as resident living fuel at present, gas pipeline is distributed in block of flats, while along with the increase of pipeline tenure of use and individual, using, do not note, the natural gas leaking phenomenon often occurs, occur that poisoning, the fire caused by rock gas, blast etc. cause casualties and the accident of economic loss.Therefore in residential houses, be badly in need of a kind of warning device is installed, when natural gas leakage to the people of premises with caution.
The utility model content
The purpose of this utility model is to provide a kind of based on computer-controlled residential houses natural gas warning device, the problem that can not find in time to solve current generation natural gas leaking phenomenon.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: described warning device comprises host scm, alarm, keyboard, A/D converter, data processing circuit, smell sensor and valve-off control circuit, the sampled signal output terminal of smell sensor is connected to the pending signal input part of data processing circuit, the sensor signal of data processing circuit is processed the analog signals input end that output terminal is connected to A/D converter, the digital quantity signal output terminal of A/D converter is connected to the sampled signal input end of host scm, two control signal output terminals on described host scm are connected respectively to the control signal input end of alarm and valve-off control circuit, the control signal output terminal of keyboard is connected to the control signal input end on host scm.
The utlity model has following beneficial effect: the utility model is by arranging smell sensor, can check out at short notice whether gas pipeline leaks, if leakage situation occurs, send chimes of doom, can remind in time the resident to rescue and evacuate, avoid casualties.
The accompanying drawing explanation
Fig. 1 is the utility model control principle drawing.
