The structured flowchart of the Intellective Fire Alarm System for the air conditioner that embodiment is provided；For convenience of description, it illustrate only and this implementation
The related part of example, as shown in the figure：
A kind of Intellective Fire Alarm System of air conditioner, including：Infrared temperature sensor 10, tumbler 20 and microprocessor
Device MCU30.Wherein, infrared temperature sensor 10 is arranged on tumbler 20, and a rotation is collectively constituted with tumbler 20
Scanning means, tumbler 20 can carry out rotation back and forth on a preset condition based；Infrared temperature sensor 10 is filled with rotation
Body surface where putting 20 pairs of air conditioners in room carries out temperature scanning back and forth and obtained to the feedback of Micro-processor MCV 30
The temperature data taken；It is, in general, that the rotary scanning device is arranged on the air door of air conditioner.Micro-processor MCV 30 is received
After the temperature data that infrared temperature sensor 10 feeds back, differentiation is compared with default Temperature-time relation；When detecting temperature
When degrees of data meets default exceptional condition, fire alarm processing is carried out to user by internet.
As a preferred embodiment, the structure of Micro-processor MCV 30 can be as shown in Figure 2.Referring to Fig. 2, micro- place
Reason device MCU30 includes：

When implementing, it is desirable to which the highest measurement temperature of infrared temperature sensor 10 is greater than 100 degrees Celsius.Air conditioner
Intellective Fire Alarm System fire alarm function can by remote control select open and close, to by same red
Outer temperature sensor 10, can both realize room temperature control, can be used for realizing fire alarm.
Embodiment two：
Fig. 3 is the implementation process figure for the fire alarm control method that second embodiment of the invention is provided；For convenience of description,
Part related to the present embodiment is illustrate only, as shown in the figure：
Step S1, control infrared temperature sensor is rotated with tumbler according to preset time-angle conditions, to air conditioner
Body surface in the room of place carries out temperature scanning, and feeds back acquired temperature data.
After the fire alarm function of Intellective Fire Alarm System is opened, control infrared temperature sensor is with tumbler
According to it is default when m- angle conditions rotate, temperature scanning back and forth is carried out to the body surface in room where air conditioner, and
Acquired temperature data is fed back to Micro-processor MCV.It should be noted that the Intellective Fire Alarm System function of the air conditioner
It should be avoided in and used in the room with the presence of high temp objects, often there is the place of naked light such as kitchen, smoking seat.If
In winter, it should also avoid opening the fire alarm function in the room for open infrared electric heater.Because these room internal memories
High temperature household electrical appliances or the kitchen tools that catch fire, rely solely on infrared temperature sensor 10 and cannot be distinguished by disaster hidden-trouble or normally make
With.
Further, as shown in figure 4, step S1 includes：
Step S11, determines the maximum rotation scope of tumbler, divides equally the maximum rotation scope according to rotational angle
For multiple scanning areas.
When implementing, the maximum rotation scope of tumbler is the maximum scan scope of infrared temperature sensor,
The maximum rotation scope is first divided into several scanning areas according to rotational angle.Explained below with an instantiation
Explanation.Assuming that the scanning range of a certain tumbler be with air conditioner into [30 °, 150 °] scope, infrared temperature sensor and
The rotary scanning device A that tumbler is combined, is divided into 40 scanning areas, the scanning angle in each region of correspondence by room
For 3 °, as shown in Figure 5.
Step S12, control infrared temperature sensor starts once with tumbler every preset time t 1, successively to described
Body surface in multiple scanning areas carries out temperature scanning respectively.
After scanning area has been divided, control infrared temperature sensor starts one with tumbler every preset time t 1
It is secondary, temperature scanning is carried out respectively to the body surface in the multiple scanning area successively.When implementing, preset time t 1
It can be any time more than 10 seconds and less than 300 seconds, can be adjusted according to the use environment of air conditioner.Continue to scheme
Exemplified by scanning subregion schematic diagram shown in 5, it is assumed that preset time t 1 is 30 seconds, then infrared temperature sensor is controlled with tumbler
Start once within every 30 seconds, to each scanning area successively to carrying out single pass, that is, be so that red on tumbler
In outer temperature sensor sequential scanning room in 40 scanning areas body surface temperature.
Step S13, controls the infrared temperature sensor sequentially to feed back what is obtained respectively in the multiple scanning area
Temperature data.
In this step S13, infrared temperature sensor is in preset time t 1 to multiple（It is 40 in upper example）Scanning area
Body surface in domain is carried out after temperature scanning respectively, is each swept according to sequencing to Micro-processor MCV feedback is acquired
Retouch the temperature data in region：For 40 scanning areas, infrared temperature sensor will sequentially feed back 40 temperature datas.
After step S2, the temperature data for receiving the infrared temperature sensor feedback, enter with default Temperature-time relation
Row compares differentiation.
Infrared temperature sensor has sequentially been fed back after the temperature data in each scanning area, and Micro-processor MCV will be received
To temperature data and default Temperature-time relation be compared differentiation.In this step, default Temperature-time relation
Two classes of difference, one kind is normal condition, and another is exceptional condition.In general, in order to set it is normal and abnormal temperature-when
Between relation, in addition it is also necessary to preset the size of several Common Parameters, such as the maximum of T 1 for the temperature that can often detect in room,
Disaster hidden-trouble critical temperature value Tm, continuous abnormal number of times critical value N, Abnormal lasting critical value TIME1, accumulative frequency of abnormity
Critical value M and abnormal cumulative time critical value TIME2 etc..
Specifically, T1 is the maximum for the temperature that often may detect that in room.Because interior generally has boiling water
Deng high-temp liquid, water temperature is ideally 100 DEG C, it is considered to influence of the atmospheric gas pressure to boiling point（Air pressure is bigger, and boiling point is got over
It is high；Conversely, air pressure is lower, boiling point is lower.The Qinghai-Tibet Platean of China, more than 4000 meters of mean sea level, is referred to as " roof of the world ".
Herein, the boiling point of water does not all reach 100 DEG C throughout the year, and the boiling point of most area water is 84 DEG C~87 DEG C）And measurement error, institute
With default T1 values preferably between 95 DEG C -105 DEG C.
Tm is default disaster hidden-trouble critical temperature value.Temperature value is higher than Tm, and explanation may have disaster hidden-trouble, and combine
Time parameter can decide whether to be implicitly present in disaster hidden-trouble.Default disaster hidden-trouble critical temperature value Tm must be that air-conditioning is infrared
The temperature value that temperature sensor can be measured, and less than the temperature value of general combustible burning-point, typically could be arranged to big
Any temperature value in 120 DEG C and less than 200 DEG C.The maximum measured temperature value of such as a certain infrared temperature sensor is 150 DEG C,
And in general family, paper is the thing for being easiest to catch fire, and the burning-point of paper has also been up to 183 DEG C, therefore in the case, Tm can
To be set to 150 DEG C in advance.
Continuous abnormal number of times critical value N and accumulative frequency of abnormity critical value M be respectively in the first preset time period T11,
The temperature data that Micro-processor MCV is received is more than or equal to the critical of default disaster hidden-trouble critical temperature value Tm number of times
Value.As long as the temperature data obtained in the first preset time period T11, in some scanning area have more than continuous n times or
It is more than or equal to default disaster hidden-trouble critical temperature value Tm, as exceptional condition more than person is accumulative M times.
TIME1 and TIME2 are respectively the Abnormal lasting critical value and abnormal cumulative time critical value of setting, i.e., a certain
Acquired temperature data is critical more than or equal to default disaster hidden-trouble in the second preset time period T12 in scanning area
Temperature value Tm duration reaches TIME1 or the cumulative time reaches TIME2, as exceptional condition, can carry out fire report
Alert processing.Likewise, according to the difference of air conditioner use environment, Abnormal lasting critical value TIME1 can be set to be more than 3
Minute and any time less than 60 minutes and abnormal cumulative time critical value TIME2 can be then more than 3 minutes and be less than
Any time of 120 minutes.Two time critical values be able to can also be differed with identical.Any limitation is not done herein.
Step S3, when detecting the temperature data and meeting default exceptional condition, fire alarm is carried out by internet
Processing.
After the temperature data received and default Temperature-time relation are compared by Micro-processor MCV, if sentenced
It is disconnected to meet exceptional condition, i.e., the temperature number said before obtained in the first preset time period T11, in some scanning area
Either it is more than or equal to default disaster hidden-trouble critical temperature value Tm for more than accumulative M times or the according to having more than continuous n times
Temperature data in two preset time period T12, acquired in some scanning area faces more than or equal to default disaster hidden-trouble
Boundary temperature value Tm duration reaches that TIME1 or cumulative time reach TIME2, that is, is considered as and meets exceptional condition, can be with
Carry out fire alarm processing.
In other words, if all temperature datas that Micro-processor MCV is received be smaller than disaster hidden-trouble critical temperature value Tm,
Even both less than T1, then illustrate the object temperature in room be all it is normal, i.e. environment it is safe.Even if having be more than or
Equal to default disaster hidden-trouble critical temperature value Tm temperature data, as long as being unsatisfactory for above-mentioned continue or cumulative number, time
Exceptional condition, it is all safe to be just believed that object or environment.
Above-mentioned control method is illustrated with a specific exceptional condition decision rule below.Preset：
, into 40 scanning areas are divided into the range of [30 °, 150 °], the scanning angle in each region of correspondence is 3 ° with air conditioner,
Preset time t 1 is 30 seconds, T1 is 105 DEG C, disaster hidden-trouble critical temperature value Tm is 150 DEG C, and：
When continuous 20 times of temperature data in some scanning area（That is N=20）Above or continue 10 minutes（That is TIME1=
10 minutes）It is not less than Tm above（Tm is 150 DEG C）, that is, exceptional condition is met, it is necessary to start alarm；Or
Temperature data in some scanning area was not less than Tm in 15 minutes（Tm is 150 DEG C）Reach accumulative 24 times（That is M
=24）It is above or accumulative more than 12 minutes（That is TIME2=12 minute）, that is, exceptional condition is met, it is necessary to start alarm.
Example one：In the scanning area where 60 ° of angles, the temperature scanning result of continuous 30 times is as follows：
Table one
| Number of times | Temperature value DEG C | Number of times | Temperature value DEG C | Number of times | Temperature value DEG C |
| 1 | 130 | 11 | 150 | 21 | 145 |
| 2 | 135 | 12 | 150 | 22 | 140 |
| 3 | 140 | 13 | 150 | 23 | 135 |
| 4 | 145 | 14 | 150 | 24 | 130 |
| 5 | 150 | 15 | 150 | 25 | 125 |
| 6 | 150 | 16 | 150 | 26 | 120 |
| 7 | 150 | 17 | 150 | 27 | 115 |
| 8 | 150 | 18 | 150 | 28 | 110 |
| 9 | 150 | 19 | 150 | 29 | 105 |
| 10 | 150 | 20 | 150 | 30 | 100 |
From upper table one it can be seen that, although the 5th to the 20th time it is continuous have 16 times be all 150 DEG C, that calculates continues
Time TIME1 is 8 minutes, and cumulative time TIME2 is also 8 minutes, but does not meet any one alert if, so not having
There is alarm.And after the 29th time, the temperature data of acquisition is 105 DEG C, now, into safe condition.
Example two：In the scanning area where hexagonal angle degree, the temperature scanning result of continuous 30 times is as follows：
Table two
| Number of times | Temperature value DEG C | Number of times | Temperature value DEG C | Number of times | Temperature value DEG C |
| 1 | 100 | 11 | 150 | 21 | 150 |
| 2 | 105 | 12 | 150 | 22 | 150 |
| 3 | 110 | 13 | 150 | 23 | 150 |
| 4 | 115 | 14 | 150 | 24 | 150 |
| 5 | 120 | 15 | 150 | 25 | 150 |
| 6 | 125 | 16 | 150 | 26 | 150 |
| 7 | 130 | 17 | 150 | 27 | 150 |
| 8 | 135 | 18 | 150 | 28 | 150 |
| 9 | 140 | 19 | 150 | 29 | 150 |
| 10 | 145 | 20 | 150 | 30 | 150 |
From upper table two as can be seen that the 11st time to the 30th time continuous 20 times are all 150 DEG C, the duration calculated
TIME1 is 10 minutes, and cumulative time TIME2 is also 10 minutes.No matter default exceptional condition is with frequency of abnormity or with exception
Time is decision rule, is full sufficient exceptional condition, judges that rotary scanning device hexagonal angle degree has disaster hidden-trouble, microprocessor
MCU is alarmed by internet to user.
Example three：In the scanning area where 100 ° of angles, the temperature scanning result of continuous 30 times is as follows：
Table three
| Number of times | Temperature value DEG C | Number of times | Temperature value DEG C | Number of times | Temperature value DEG C |
| 1 | 130 | 11 | 150 | 21 | 140 |
| 2 | 140 | 12 | 150 | 22 | 150 |
| 3 | 150 | 13 | 150 | 23 | 150 |
| 4 | 150 | 14 | 150 | 24 | 150 |
| 5 | 150 | 15 | 140 | 25 | 150 |
| 6 | 150 | 16 | 150 | 26 | 150 |
| 7 | 150 | 17 | 150 | 27 | 145 |
| 8 | 150 | 18 | 150 | 28 | 150 |
| 9 | 150 | 19 | 150 | 29 | 150 |
| 10 | 140 | 20 | 150 | 30 | 150 |
From upper table three as can be seen that the measuring section that continuous 20 times are all 150 DEG C is not present.But in 30 measurements,
Accumulative to have 24 measurement temperatures to reach 150 DEG C, the lasting TIME1 calculated is 1.5 minutes, and cumulative time TIME2 is 12 points
Clock.No matter default exceptional condition is, using cumulative number or using the cumulative time as decision rule, to be full sufficient exceptional condition, judge
There is disaster hidden-trouble in 100 ° of angles of rotary scanning device, Micro-processor MCV is alarmed by internet to user.
