No generation fire, and determine the direction of fire source.
The memory 20 include at least a type of readable storage medium storing program for executing, the readable storage medium storing program for executing include flash memory,
Hard disk, multimedia card, card-type memory (for example, SD or DX memory etc.), random access storage device (RAM), static random are visited
It asks memory (SRAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), may be programmed read-only deposit
Reservoir (PROM), magnetic storage, disk, CD etc..The processor 30 can be central processing unit (Central
Processing Unit, CPU), controller, microcontroller, microprocessor or other data processing chips etc..
The fire alarm system 10 includes detection module 101, judgment module 102, trigger module 103, comparison module 104
And fire source analysis module 105.The module is configured to be held by one or more processors (the present embodiment is processor 30)
Row, to complete the present invention.The so-called module of the present invention is to complete the computer program code segments of a particular, instruction set.The memory 20
The data such as the program code for storing the fire alarm system 10.The processor 30 is for executing in the memory 20
The program code of storage.
The detection module 101 is used for through the smokescope and temperature in ultrasound examination predeterminable area.Specific implementation
In example, the detection module 101 is judged described default by detecting the physical parameter that the ultrasonic wave is generated in transmission
Smokescope and temperature in region, wherein the physical parameter of the ultrasonic wave includes at least: the attenuation of the ultrasonic wave,
Frequency shift (FS) and velocity of wave.
In conjunction with Fig. 2, the detection module 101 further include ultrasonic wave module 1001, smokescope analysis module 1002 and
Temperature analysis module 1003.
The ultrasonic wave module 1001 is used to emit ultrasonic wave and receives the echo of the ultrasonic wave.
The smokescope analysis module 1002 is used for the attenuation of the ultrasonic wave according to echo analysis, and according to institute
State the smokescope that attenuation analyzes the predeterminable area.Specifically, the attenuation is smaller, the smog of the predeterminable area is dense
It spends lower；The attenuation is bigger, and the smokescope of the predeterminable area is higher.
The temperature analysis module 1003 is according to the first time and the second of the reception echo for emitting the ultrasonic wave
Time analyzes the temperature of the predeterminable area.In specific embodiment, the temperature analysis module 1003 is according to the first time
With the difference of second time, velocity of wave when ultrasonic wave transmitting is calculated, and analyzes the temperature of the predeterminable area with this.
The difference is bigger, and the calculated velocity of wave is lower, so that the temperature for analyzing the predeterminable area is lower.The difference is got over
Small, the calculated velocity of wave is higher, so that the temperature for analyzing the predeterminable area is higher.
The judgment module 102 judges whether that fire occurs according to the smokescope and the temperature.It below will be detailed
How thin introduce judges whether that fire occurs according to the smokescope and the temperature.
In a preferred embodiment, when temperature, which is higher than the first preset value and smokescope, is higher than the second preset value, then institute
It states judgment module 102 and judges that fire occurs for the predeterminable area.
In another preferred embodiment, when the temperature is lower than the first preset value and the smokescope is default lower than second
When value, then the judgment module 102 judges that fire does not occur for the predeterminable area.
In another preferred embodiment, when the temperature is much higher than the first preset value and the smokescope is pre- lower than second
If when value third preset value will be adjusted under second preset value, if the smokescope is higher than the third preset value, institute
It states judgment module 102 and judges that fire occurs for the predeterminable area.
In another preferred embodiment, when the temperature is lower than the first preset value and the smokescope is pre- much higher than second
It is described to sentence if the temperature is higher than the 4th preset value if when value the 4th preset value will be adjusted under first preset value
Disconnected module 102 judges that fire occurs for the predeterminable area.
The trigger module 103 is for when a fire, triggering alarm of fire.
After judging that fire occurs for the predeterminable area, the direction for how confirming fire source will be described in detail below.
The comparison module 104 is for comparing echo-signal frequency and default ultrasonic signal frequency.In specific embodiment,
Since when fire occurs, smoke particle can be mobile from high concentration toward low concentration direction, therefore the tranmitting frequency of the ultrasonic wave
From the reception frequency of the echo there are different, the direction of fire source can determine whether with this.
The fire source analysis module 105 is used to be higher than the default ultrasonic signal frequency when the echo-signal frequency
When, then judge the fire source direction for the direction of the launch of the ultrasonic wave；When the echo-signal frequency is default super lower than described
When acoustic signals frequency, then judge the fire source direction for the opposite direction of the ultrasonic wave direction of the launch；And work as the echo
When signal frequency is equal to the default ultrasonic signal frequency, then judge the fire source direction for the transmitting position of the ultrasonic wave
It sets.
Above embodiments can accurately judge whether the predeterminable area occurs fire, and when a fire, quasi-
The true direction for judging fire source.
