Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The working principle of the scheme is briefly described as follows:

when the alarm operates, the smoke sensor can detect the surrounding smoke concentration in real time and send the smoke concentration to the processor, the processor receives data and extracts the data from the memory for comparison, when the smoke concentration exceeds a preset value, the processor turns on the temperature sensor, the temperature sensor detects the surrounding temperature again and sends the temperature to the processor, the processor also extracts a numerical value from the memory for comparison, when the temperature also exceeds the preset value, the processor turns on the flame sensor, the flame sensor detects flames, a progressive detection mode is adopted, firstly, the electric quantity burden caused by the simultaneous long-time operation of the three sensors is saved, secondly, the accidental alarm caused by a certain condition but not a fire disaster is avoided, when the three conditions are met simultaneously, the fire disaster is determined, and at the moment, the processor controls the GPS positioner to determine the accurate position, the electronic components are arranged in the alarm, in order to prevent the influence of overhigh external temperature on the operation of the components, the processor controls the humidifier driver to turn on the humidifier and carry out cooling treatment on the internal components, and as the components all speak water-proofing treatment, the humidifier does not influence the components when cooling the interior, and simultaneously, the power supply module supplies power for various components, the power supply module adopts a lithium battery pack, the power consumption is greatly saved because only the smoke sensor of the detection module is in a normally open state, and meanwhile, the lithium battery pack has the characteristics of long service life and high energy conversion ratio and can realize the purpose of continuous operation.

Further, waterproof processing setting is all done inside the alarm to GPS locator, smoke transducer, temperature sensor, flame sensor, treater, memory, power module, alarm driver, alarm, WIFI wireless communication module, so all do waterproof processing in order to prevent to use the humidifier to cause the influence to the operation of components and parts when cooling down the processing inside.

Furthermore, the smoke sensor is in a normally open state, the temperature sensor and the flame sensor are in a normally closed state, and a progressive detection mode is adopted, so that the electric quantity burden caused by the simultaneous long-time operation of the three sensors is saved, and the accidental alarm caused by fire but not caused by a certain condition is avoided.

Furthermore, the flame sensor adopts a far infrared flame sensor, the far infrared flame sensor can detect infrared light with the wavelength within the range of 700-1000 nanometers, the detection angle is 60, when the wavelength of the infrared light is near 880 nanometers, the sensitivity of the infrared light is maximized, the far infrared flame probe converts the intensity change of the external infrared light into the change of current, the change is reflected as the change of a numerical value within the range of 0-255 through an A/D converter, and the stronger the external infrared light is, the smaller the numerical value is; the weaker the infrared light, the larger the value.

Furthermore, the smoke sensor adopts an ion type smoke sensor, the ion type smoke sensor is a sensor with advanced technology and stable and reliable work, is widely applied to various fire alarm systems, and has far better performance than a gas-sensitive resistor type fire alarm.

Furthermore, the alarm adopts audible and visual annunciator, adopts two kinds of alarm modes of sound and light, and it is more obvious to remind the effect, and especially in this kind of chaotic noisy place in the scene of a fire, it exists very necessarily.

Furthermore, the processor adopts STM32F407 processing chip, and STM32F407 processing chip can accomplish and just receive the data and the processing from each sensor, sends to communication terminal through WIFI wireless communication module simultaneously to the task of the corresponding driver of control.

Furthermore, the temperature sensor adopts a non-contact temperature sensor, the upper limit of measurement is not limited by the temperature resistance degree of the temperature sensing element, so that the maximum measurable temperature is not limited in principle, for the high temperature of more than 1800 ℃, a non-contact temperature measurement method is mainly adopted, the radiation temperature measurement is gradually expanded from visible light to infrared ray along with the development of the infrared technology, the radiation temperature measurement is adopted from below 700 ℃ to normal temperature, and the resolution is very high.

It is worth noting that: the treater, memory, temperature sensor, smoke transducer, flame sensor, alarm driver, LED lamp driver, humidifier driver, alarm, humidifier, LED lamp, power module etc. in this scheme are the circuit or the material object commonly used among the prior art, and the innovation of this scheme does not lie in single circuit, but the cooperation of several module and circuit is used and is reached accurate location conflagration scene and send for the fire fighter, guarantees the purpose that the alarm can normal operating under high temperature state simultaneously.
