Abstract

Provided is a household electronic nose, used to detect gas in home environment, especially smog, carbon monoxide, and other toxic gases, thereby protecting personal and property safety at home. The electronic nose comprises an ATmega16L controller (1), a gas detection module (2), a liquid crystal display module (3), a local alarm module (4), a remote alarm module (5), and a power module (6). The household electronic nose uses a low power consumption microprocessor ATmega16L singlechip as a control center, and simple circuits are arranged on periphery, so as to detect smog, combustible gases, etc. in the home environment and alarm. The household electronic nose is characterized by simple structure, good performance, low cost, etc.

Description

The domestic electronic nose

Technical field

The utility model relates to a kind of domestic electronic nose; adopt 8 low-power consumption microprocessor ATmega16L single-chip microcomputers to be the control core specifically; modules such as peripheral collocation corresponding gas detection module, liquid crystal display display module and remote alarms; finish the detection and the warning of inflammable gas in the family jointly, with protection people's the person and property safety.

Background technology

Electronic Nose is that a kind of optionally chemical sensor array and corresponding pattern recognition system are formed by having part, instrument that can the simple or complicated smell of identification is analysis, identification and the detected gas of a kind of novelty of growing up the nineties and the bionical gas analysis instrument of most of volatile matter.Along with the improving constantly of sensor and artificial intelligence technology, the function and application of Electronic Nose has also obtained very big development in recent years.

In recent years, fire becomes one of China's disaster that often property sent out and destructiveness and influence power are the strongest already, and especially family fire has caused serious harm to people's life security and property safety especially.Along with the fast development of economy and urban construction, the urban rhythm of life is accelerated, and things such as work, overtime work, dinner party usually cause situation unmanned in the family.If unexpected stormses such as breaking out of fire in the family, gas leak at this moment, usually because take place more hiddenly cause finding later, cause heavy loss.

The inflammable gas that Electronic Nose Technology is applied in the home environment detects, and can in time find dangerous situation and warning, has protected people's the person and property safety, has reduced loss.

The utility model content

Technical problem to be solved in the utility model is, a kind of with low cost, simple in structure, domestic electronic nose of being easy to promote is provided.

The technical scheme that the utility model adopted is: a kind of domestic electronic nose, have controller, and also comprise the gas detection module that links to each other with controller; The liquid crystal display display module that is used for data presentation that links to each other with controller; The local alarm module that links to each other with controller; The remote alarms module that links to each other with controller; The power module that is used to provide system power supply that links to each other with controller.

Described gas detection module links to each other with the I/O of controller, and MQ-2 forms by combustible gas sensor, is used for the detection of family's smog, methane and LNG gasifaction.

Described liquid crystal display display module is used for the demonstration of gas concentration.

Described local alarm module links to each other with the I/O of controller, reports to the police in this locality when being used to detect inflammable gas.

Described remote alarms module links to each other with the serial ports of controller, adopts the wireless communication gsm module, is used for remote alarms.

Described power module is used to provide system power supply.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and example.

Domestic electronic nose of the present utility model; adopt 8 low-power consumption microprocessor ATmega16L single-chip microcomputers to be the control core; modules such as the corresponding gas detection module of peripheral collocation, liquid crystal display display module, local alarm module and remote alarms; finish the detection and the warning of inflammable gas in the family jointly, with protection people's the person and property safety.

As shown in Figure 1, domestic electronic nose of the present utility model has controller (1), also comprises the gas detection module (2) that links to each other with controller (1); The liquid crystal display display module (3) that links to each other with controller (1); The local alarm module (4) that links to each other with controller (1); The remote alarms module (5) that links to each other with controller (1); The power module (6) that links to each other with controller (1).

As shown in Figure 2, gas detection module of the present utility model is made up of inflammable gas, smoke transducer MQ-2, and this sensor has the output of two-way signal, analog quantity output and Transistor-Transistor Logic level output, when measuring concentration greater than setting concentration, output low level is given single-chip microcomputer, realizes reporting to the police.

As shown in Figure 3, liquid crystal display display circuit of the present utility model links to each other with the I/O mouth of controller, is used for the demonstration of gas concentration.

As shown in Figure 4, local alarm module of the present utility model links to each other with the I/O mouth of controller, is made up of hummer, is used for the alarm of combustable gas concentration when too high.

As shown in Figure 5, remote alarms module of the present utility model links to each other with the serial ports of controller, is made up of wireless communication TC35 module, can realize the remote short messages warning when breaking out of fire or combustable gas concentration are too high among the manager.
