Abstract
A smoke detection alarm system includes a smoke sensor, a temperature sensor and a flame sensor. The smoke sensor, the temperature sensor and the flame sensor are connected with the main control module through a circuit; and the main control module is connected with a display screen, and a sound and light alarm device. The smoke sensor is installed at a position far away from the cooking place in the kitchen; the temperature sensor is installed at a door of the kitchen; and the flame sensor is installed at a position close to the cooking place in the kitchen cooking. The smoke detection alarm system provided by the utility model uses a plurality of sensors for multiple-point collection, and improves accuracy of the collected data; and the date is processed by a fuzzy algorithm, so that the test data is more accurate. The system can automatically detect smoke concentration, and determines whether the concentration exceeds the standard by comparison with the preset data, so as to control normal starting of the alarm and prevent fires.
Description
Technical field
A kind of smoke detecting alarm system of the utility model.
Background technology
Mainly take the smoke detecting alarm system of single-sensor single-point acquiring data as main, even utilize multipoint acquisition, do not use the fuzzy algorithm treatment technology in the market, the accuracy of image data is not high yet.Particularly higher as the housed device cost.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of smoke detecting alarm system, has adopted a plurality of sensor multipoint acquisitions, and the accuracy that has strengthened image data is carried out simultaneously fuzzy algorithm and processed, thereby makes test data more accurate.This system's energy automatic detection smokescope, thereby whether the contrast initialize data exceeds standard the normal startup of control alarm is stopped the generation of fire better with this.
Above-mentioned purpose of the present utility model is to realize by such technical scheme: smoke detecting alarm system, comprise: smoke transducer, temperature sensor, flame sensor, described smoke transducer, temperature sensor, flame sensor connect main control module by circuit, described main control module connects display screen, and described main control module connects acoustic-optic alarm.
Described smoke transducer be installed on the kitchen from culinary art place than distant positions, described temperature sensor is installed on the doorway, kitchen, described flame sensor is installed on culinary cuisine place closer locations.
Described acoustic-optic alarm is provided with the delayed alarm module.Described main control module connects audio alert module, upper computer control module.Described main control module is by solid-state relay connected electromagnetic valve, solenoid control automatic shower nozzle, exhaust fan.Described main control module comprises single chip computer AT 89C51.
This system comprises a primary power, an auxiliary power.
A kind of smoke detecting alarm system of the utility model has adopted the method for smoke transducer, temperature sensor, flame sensor multipoint acquisition, and the accuracy that has not only strengthened image data is more carried out fuzzy algorithm and processed, thereby makes test data more accurate.
Display screen can show the concentration value function of flammable smog, has more ensured the accuracy of smoke alarm.
A kind of smoke detecting alarm system of the utility model is provided with delayed alarm module, audio alert module, and delayed alarm function and voice alarm function are all relatively novel in like product.The more hommization of delayed alarm function is so that the alarm reliability increases.Simultaneity factor has fault alarm function, can send failure alarm signal when hardware fault appears in system.And audio alert is conducive to the fire department on-the-spot fire of eliminating that arrives in the very nick of time.Upper computer control module can in time pass to fire department with the fire place that records in advance.

Embodiment
As shown in Figure 1, smoke detecting alarm system, comprise: smoke transducer 1, temperature sensor 2, flame sensor 3, described smoke transducer 1, temperature sensor 2, flame sensor 3 connect main control module 4 by circuit, described main control module 4 connects display screen 5, and described main control module 4 connects acoustic-optic alarm 6.
As shown in Figure 2, described smoke transducer 1 be installed on the kitchen from culinary art place 7 than distant positions, described temperature sensor 2 is installed on the doorway, kitchen, described flame sensor 3 is installed on culinary cuisine place 7 closer locations.
Described acoustic-optic alarm 6 is provided with the delayed alarm module.Described main control module 4 connects audio alert module, upper computer control module.Described main control module 4 is by solid-state relay connected electromagnetic valve, solenoid control automatic shower nozzle, exhaust fan.Described main control module 4 comprises single chip computer AT 89C51.
This system comprises a primary power (AC power), an auxiliary power (accumulator).Under normal circumstances, pass through ac power supply.When occur having a power failure or AC power when breaking down, accumulator for subsequent use is kept whole system to the MAX831 chip power supply and is continued normal operation.Thereby guarantee that this system can both work in 24 hours.
A kind of smoke detecting alarm system of the utility model, the advanced technology that has adopted smoke transducer 1, temperature sensor 2, flame sensor 3 multipoint acquisition data and Fuzzy processing to analyze.
Lay MQ-2 type smoke transducer from culinary art place 7 than distant positions in the kitchen, this transducer sensitivity is high, and corresponding fast, antijamming capability is strong, and stable performance is cheap.But it is larger only to lay MQ-2 type smoke transducer detection error.Lay the DS18B20 temperature sensor on the doorway, kitchen, this sensor easy-to-connect can be applicable to multiple occasion after being packaged into, wear-resisting anti-bumping, and volume is little, and is easy to use.Lay sensor RD-913F flame sensor in culinary cuisine place 7 closer locations.
Respectively detection by above-mentioned three sensors is also carried out the data message fusion parameters and is estimated, selects the fuzzy controllers of the single output of three inputs to judge whether to catch fire.
This system comprises display screen, is used for showing the concentration value function of flammable smog.In order to reduce as far as possible error, LCD display can show the concentration value of flammable smog, and can switch to the state of setting, by keyboard setting or change warning limit value, so that user or testing staff observe smokescope and change alarm limit at any time, get rid of the situation of not catching fire because cause specific concentration reaches alarm criteria.This system has fault alarm function, can send failure alarm signal when hardware fault appears in system.
Acoustic-optic alarm 6 is provided with the delayed alarm module, possesses the delayed alarm function of 5min.1 pair of small-particle of smoke transducer is responsive, thus when culinary art, have faster reaction, thereby adopt the delayed alarm design of 5min.When this system after the fuzzy algorithm by concentration value and sensor is analyzed, when detecting that fire condition is determined to exist and during non-fault, hummer is sounded the alarm, light emitting diode begins flicker, the voice reminder circuit start is reminded the resident to note and is made good one's retreat.
This system can control solid-state relay SSR conducting after confirming fire, make solenoid valve open-minded, thereby reaches automatic shower nozzle and exhaust fan ventilation, and small fire is extinguished, and also can make conflagration reduce infringement.
This system makes a phone call 120 by voice alarm circuit, upper computer control module with automatic poking, and the place that catches fire that will record in advance reports to fire department.Can greatly shorten the time of putting rescue to good use, alleviate the condition of a disaster.
