Description
Technical field
This utility model belongs to gas detection equipment, especially a kind of Intelligent gas leakage detection equipment.
Background technology
Along with the development of petro chemical industry, kind and the range of application of inflammable, explosive, toxic gas are obtained for increase. These gases producing, transport, in use procedure once leak, it will cause poisoning, fire even explosion accident, the safety of life and property of the serious harm people. Due to the diffusibility that gas itself exists, after leaking, under the effect of external wind and concentration inside gradient, gas can spread along ground surface, form combustion explosion or toxicological hazards district in the scene of the accident, expand hazard area, once there is gas leakage accidents, corresponding measure must be taked as early as possible to be disposed, causality loss could be reduced to floor level. Timely and reliably the content of some gas in detection air, adopts an effective measure in time and remedies, take correct method of disposal, reduce the accident that leakage causes, be the essential condition avoiding causing the heavy losses of property and casualties. The detection of gas and monitoring equipment are just proposed higher requirement by this.
Summary of the invention
The purpose of this utility model is in that to overcome the deficiencies in the prior art, adopts wireless headset and alarm double-reminding pattern, solves gas leakage under noisy environment and not easily finds, the problem that transmission range is short.
This utility model solves it and technical problem is that and take techniques below scheme to realize:
It is made up of regulated power supply, ultrasonic probe, amplifying circuit, wireless headset, A/D converter, single-chip microcomputer, display screen, alarm, keyboard; Described ultrasonic probe connects amplifying circuit; Described amplifying circuit includes preamplifier and band filter; Described amplifying circuit connects wireless headset, A/D converter respectively; Described A/D converter connects single-chip microcomputer; Described display screen, alarm, keyboard connect single-chip microcomputer respectively; Described regulated power supply is powered to modules.
And, described single-chip microcomputer adopts AT89C51 single-chip microcomputer.
And, described display screen adopts 12864 LCDs.
And, described alarm adopts triple alarm modes.
This utility model advantage and having the benefit effect that
1, this utility model Intelligent gas leakage detection equipment strong anti-interference performance, can regulate sensitivity according to leak sizes.Adopt wireless headset and alarm double-reminding pattern, when there being gas to leak, the same alarm of alarm, flicker, vibration; By line earphone prompt tone, staff has discerned whether that gas leaks, wireless headset transmission range is long, and convenient detection, even if also can hear in the factory that environment is the most noisy, remind staff to adopt an effective measure in time to remedy, reduce the probability caused danger.
Accompanying drawing explanation
Fig. 1 is that this utility model structure connects block diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model embodiment is further described:
As it is shown in figure 1, a kind of Intelligent gas leakage detection equipment described in the utility model, it is made up of regulated power supply, ultrasonic probe, amplifying circuit, wireless headset, A/D converter, single-chip microcomputer, display screen, alarm, keyboard; Described ultrasonic probe connects amplifying circuit; Described amplifying circuit includes preamplifier and band filter; Described amplifying circuit connects wireless headset, A/D converter respectively; Described A/D converter connects single-chip microcomputer; Described display screen, alarm, keyboard connect single-chip microcomputer respectively; Described regulated power supply is powered to modules.
This utility model Intelligent gas leakage detection equipment, adopt ultrasonic detection technology, when measurand generation gas leaks, the sound wave of certain frequency can be produced, when ultrasonic probe captures these sound waves, through preamplifier, signal is amplified, protrude with the signal of frequency then through band filter, the signal of decay unwanted frequency, it is ensured that signal normal transmission is in wireless headset and A/D converter, by wireless headset prompt tone, staff has discerned whether that gas leaks; If there being gas to leak, the same alarm of alarm, flicker, vibration, the concentration value of display screen display gas leakage; Leaking without gas, detection equipment is in normal detection state; When brownout, warning lamp glimmers, and reminds staff to process in time, adopts an effective measure and remedy. Single-chip microcomputer is as core cell, and the digital data transmission changed by A/D converter is in display screen, alarm. This Intelligent gas leakage detection equipment supports Chinese and English operation interface, and keyboard operation, switching is simple, can set local time, ambient temperature, show on a display screen visual and clearly. Using wireless headset to expand transmission range, Leakage inspection is simple. Double-reminding pattern, solves gas under noisy environment and leaks ND problem, reduce the probability caused danger, it is to avoid cause the heavy losses of property and casualties.
It is emphasized that; embodiment described in the utility model is illustrative; rather than it is determinate; therefore this utility model is not limited to the embodiment described in detailed description of the invention; every other embodiments drawn according to the technical solution of the utility model by those skilled in the art, also belong to the scope of this utility model protection.
