Abstract
The utility model relates to a gas monitor. A single-chip microcomputer is respectively connected with a power supply, a gas-sensitive sensor, an alarm device, a storage device, a liquid crystal digital display device, an exhaust fan and a brake device. The brake device is composed of a motor and a transmission connecting rod that is connected with the motor. The transmission connecting rod is connected with an emergency shut-off valve door of a natural gas or gas pipeline. The beneficial effects of the gas monitor are that through control of the single-chip microcomputer, if detected harmful gas reaches the certain concentration, alarming is sent by the alarm device, the concentration of the harmful gas can be visually displayed, and then the harmful gas is expelled through the exhaust fan and is prevented from leaking continuously through the brake device.
Description
Technical field
The utility model relates to a kind of gas monitor.
Background technology
Along with the raising of people's living standard, coal gas, rock gas become the requisite energy in people's daily life.But coal gas, rock gas are a kind of relatively more dangerous inflammable gass, in case it is very serious that the consequence that causes occurs to leak, cause inevitable loss to people, owing to carrying the pipeline of coal gas, rock gas after long-term the use, inevitably exist and wear out, thereby cause coal gas, natural gas leaking.The infringement that causes to people in order to reduce coal gas, natural gas leaking, people have been installed gas monitor additional in the kitchen of using rock gas or coal gas, but existing gas monitor complicated structure, and only be the function that plays a warning, when coal gas, when rock gas occurs to leak, still can not in time prevent the further leakage of coal gas or rock gas.Therefore, should further improve prior art.
The utility model content
The purpose of this utility model provides a kind of gas monitor, to overcome present prior art above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of gas monitor comprises single-chip microcomputer, and described single-chip microcomputer connects respectively power supply, gas sensor, warning device, memory storage, liquid crystal digital display device, extraction fan and clamping device, and described warning device comprises light warning and sound warning circuit; Described clamping device is comprised of with the kinematic link that is connected with motor motor, and kinematic link connects the emergency cut-off valve of rock gas or gas piping.
The beneficial effects of the utility model are: the gas monitor that the utility model provides, pass through Single-chip Controlling, when the harmful gas that detects reaches finite concentration, warning device gives the alarm, and can intuitively show the concentration of current harmful gas, by exhaust apparatus harmful gas is discharged, and can prevent that harmful gas from continuing to leak by clamping device.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.
Fig. 1 is the structured flowchart of the described a kind of gas monitor of the utility model embodiment.
Among the figure:
1, single-chip microcomputer; 2, power supply; 3, pick-up unit; 4, warning device; 5, memory storage; 6, display device; 7, extraction fan; 8, clamping device.
Embodiment
As shown in Figure 1, the described a kind of gas monitor of the utility model embodiment, comprise single-chip microcomputer 1, described single-chip microcomputer 1 connects respectively power supply 2, gas sensor 3, warning device 4, memory storage 5, liquid crystal digital display device 6, extraction fan 7 and clamping device 8, described warning device 4 comprises that light warning is connected clamping device 8 and is comprised of with the kinematic link that is connected with motor motor with the sound warning circuit, and described kinematic link connects the emergency cut-off valve of rock gas or gas piping.
During concrete the use, the 12V voltage that power supply 2 provides for family's power supply, use the AT89S51 single-chip microcomputer, gas sensor 3 detects airborne harmful gas concentration, the concentration signal that detects converts output voltage signal to, and give the AT89S51 single-chip microcomputer and carry out data and process, voltage signal is converted to corresponding concentration value, and delivers in the display screen of liquid crystal digital display device 6 and show.When the harmful gas concentration that detects surpasses the upper limit alarm setting value, Single-chip Controlling warning device 4 is started working, the red LED lamp flicker of warning device 4, voice guard sends chimes of doom, while single-chip microcomputer output signal, driving extraction fan 7 starts working, discharge harmful gas within doors, driving simultaneously clamping device 8 starts working, the motor of clamping device 8 rotates, drive kinematic link the emergency cut-off valve on natural gas or the gas piping is closed, prevent that harmful gas from further leaking, memory storage 5 stores data simultaneously.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, all drops within the protection domain of the present utility model.
