Description
Technical field
The utility model belongs to electronic technology, Sensors ﹠ Testing Technology and automation field, relates to a kind of family gas intelligent safety control system.
Background technology
Along with the high speed development of urban construction and the raising of living standards of the people.Coal gas entered huge numbers of families, yet coal gas is served calamity also as a double-edged sword same often can being with that brings glad tidings to people as most convenient, most economical, the cleanest fuel.The resident is when using piped gas, owing to pipeline gas leakage, opening and fit badly or hot plate that Flame is not extinguished or user's misoperation in use, cause coal gas to overflow in a large number, thereby the tragic event of the anthracemia that causes, gas explosion have generation every year.According to incompletely statistics, the annual whole world approximately has 800,000 people to die from the liquefied gas poisoning, and the shared ratio of China is about about 1/5 of total amount.
The utility model content
The technical matters that the utility model solves is to provide a kind of family gas intelligent safety control system, to solve the shortcoming in the above-mentioned background technology.
The technical matters that the utility model solves realizes by the following technical solutions:
The family gas intelligent safety control system applicable to the average family dwelling house, comprises master controller, ultraviolet flame sensor, gas concentration sensor, gas piping solenoid valve, voice prompting device, timer, row's air exchange system and display system.Wherein, master controller adopts single-chip microcomputer, carry two phonetic alarms that can be installed in kitchen and parlor on it, and timer, display system, ultraviolet flame sensor, gas concentration sensor, gas piping solenoid valve and row's air exchange system are connected to all on the master controller; In addition, described voice prompting device comprises note amplifier and sub-controller, can be connected with main controller system very easily, and control by master controller.
In the utility model, described ultraviolet flame sensor links to each other with master controller by A/D converter with the gas concentration sensor.
In the utility model, described gas piping solenoid valve joins by driver and master controller.
In the utility model, described phonetic alarm should be installed in respectively in user's the kitchen and parlor, so that coal gas user and household monitor.
In the utility model, described gas concentration sensor includes but not limited to the CO sensor, and should install near ceiling.
After coal gas leaks, if after the ventilation of short period (such as 1 minute), the concentration that the gas concentration sensor collects indoor this harmful gas is lower than its safe concentration threshold value, this Time Controller will send shutdown signal to row's air exchange system and voice prompting device simultaneously, closes ventilation and panalarm.
If when indoor gas concentration continues to increase, when meeting or exceeding maximum secure threshold, master controller is given an order to the gas piping solenoid valve, make it close immediately the gas piping solenoid valve, and while shutdown system general supply, light indoor coal gas with the switch of anti-electricity device and set off an explosion, thereby cause secondary injury or infringement.
Advantage of the present utility model and useful being:
1), the interface is affine: regularly pronunciation prompting, self-defined setup and use time;
2), high sensitivity, fast response time, rate of false alarm are low.UV sensor only responds the ultraviolet ray in the narrow range, and insensitive to the light of other spectral range: because flame radiation is to have the gas radiation of discrete spectrum and with the solid radiation of continuous spectrum, its wavelength is in 0.1-10 μ m or wider scope, interference for fear of other signals, often utilize the ultraviolet ray of wavelength＜300nm as detectable signal, sensitivity, the false alert reduction of very favourable raising sampling;
3), three level securities protection, security performance is higher: one-level: automatic valve control; Secondary: automatic vent control; Three grades: auto-breaking control;
4), realize simply, cost is low: adopt microprocessor to realize the integral body control of system as controller, be proven technique, easy to implement, drop into not highly, be conducive to promotion and implementation.
Description of drawings
Fig. 1 is the schematic diagram of the utility model preferred embodiment.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Preferred embodiment referring to the family gas intelligent safety control system of Fig. 1, in this embodiment, at first utilize QM-10 type gas sensor the gas concentration in the room air that detects to be changed into the analog voltage signal of 0-5V, after low-pass filter filtering, deliver to and carry out the A/D conversion in the A/D chip, deliver to again in master controller 3.
Then utilize the ultraviolet flame probe of the ultraviolet flame sensor 2 that can detect the light source of wavelength in 760nm～1100nm scope that flame is detected, export to master controller 3 by low-pass filter filtering again through over-voltage comparator.
When situation is normal; voltage comparator sends the order of the pipe electromagnetic valve 1 that continues to turn on the gas-fire to master controller 3; if detect suddenly and do not have flame (watered by water such as flame and do not have etc.); then send the order of closing gas piping solenoid valve 1 to master controller 3; these parts are equivalent to a switch in system, play the effect of blowout protection.3 pairs of two road signals of master controller carry out making corresponding reaction after the analysis-by-synthesis.
If the user normally uses coal gas, the points for attention (as: coal gas uses, and please notes safety etc.) during master controller 3 control voice prompting devices 4 fixed time airplay gas safeties use, reminding user correctly uses coal gas; (because when the concentration of CO in the environment during above 100 ppm, human body will produce dizziness, the sense of discomfort such as weak when gas concentration reaches the secure threshold minimum that gas concentration sensor 6 sets; When CO concentration surpasses 600 ppm, can cause death by suffocation in a short time; Therefore, for guaranteeing human-body safety, the secure threshold of the CO of application settings gas concentration sensor 6 is 50ppm in the present embodiment) time, timer 5 is used for auxiliary master controller 3 and row's air exchange system 7 carries out work.At this moment, master controller 3 sends the caution order: on the one hand, the warning lamp in the display system 8 brightens; On the other hand, be unlikely to too flurried for making the user, in case the state of affairs further worsens, voice prompting device 4 also will point out and tell the method for user's processing accident when reporting to the police, simultaneously, and gas concentration in master controller 3 row of driving air exchange system 7 dilution chamber.
Above demonstration and described ultimate principle of the present utility model, 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; that describes in above-described embodiment and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
