The utility model structure is simple, easy to operate, safe and reliable, practical, and input and warning are accurately.
Accompanying drawing explanation
The utility model is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of gas detection module of the present utility model.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
With reference to Fig. 1-2, this embodiment is by the following technical solutions: flammable gas detecting alarm device, comprise single-chip microcomputer 1, gas detection module 2, pilot lamp hummer 3, robot drives module 4 and remote alarms control module 5, single-chip microcomputer 1 is connected with remote alarms control module 5 with gas detection module 2, pilot lamp hummer 3, robot drives module 4 respectively; Described gas detection module 2 comprises gas concentration sensor 21, Acquisition Circuit 22, AD converter 23 and comparer 24, gas concentration sensor 21 is connected with AD converter 23 by Acquisition Circuit 22, AD converter 23 is connected with comparer 24, and comparer 24 is connected with pilot lamp hummer 3, remote alarms control module 5.
It should be noted that described robot drives module 4 is connected with air valve by relay.
It should be noted that described single-chip microcomputer 1 adopts single-chip microcomputer STC12C5410AD.
In addition, described gas concentration sensor 21 adopts catalytic type combustible gas sensor.
This embodiment obtains binary number corresponding to gas concentration value by Detection Circuit with A/D in single chip microcomputer, compare with the warning critical value of default, if be in alarm range, then realize actuation of an alarm by the flicker of light emitting diode and piping of hummer, solve the warning problem of inflammable gas; When system is in alarm condition, realize remote alarms by operational relay to control, also can carry out driving device by operational relay manually to do---open or close air valve, realize the automatic process of reporting to the police, remove or enter alarm condition, alarm condition was there is before instruction, now system is in normal operating conditions, only alarm lamp flicker, and hummer cuts out, this state can be cancelled by manual key, easy to operate.
This embodiment structure is simple, easy to operate, safe and reliable, practical, and input and warning are accurately.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
