An isolation chip is added after the signals of the main control chip of the main control terminal 2 are output, so that the interference of an external power supply to the main control chip of the main control terminal 2 is effectively prevented.
Of course, the gas valve closing device 31, the power supply disconnection device 32 and the fire extinguisher control device 33 may be connected to the control module 22 of the general control terminal 2 through a communication network.

When the smoke detector works, the smoke sensor 12 is started to capture smoke concentration data and combustible gas concentration, the temperature sensor 11 is started to collect ambient temperature data, and the infrared temperature sensor 13 is started to capture infrared temperature data. The information processing module 21 determines whether the received smoke concentration data and the received combustible gas concentration data exceed corresponding thresholds, and whether the received ambient temperature data and the received infrared temperature data exceed corresponding thresholds, and if any data exceed corresponding thresholds, the CCD camera 14 is started again to photograph the site, that is, to acquire images of the site. The image recognition program is called through the information processing module 21, the flame form is extracted, whether the flame form is abnormal or not is judged, if the flame form is abnormal, the control module 22 transmits the processing data of the information processing module 21 to the display control module 4 through the communication network, the processing data of the information processing module is displayed through the display area, and the user operation instruction is inquired through the instruction area.
The threshold values of the smoke concentration data, the combustible gas concentration data, the environment temperature data and the infrared temperature data are respectively determined by the following methods:
wherein, the smoke concentration data and the combustible gas concentration data threshold are calibrated and determined by pre-grading. Fig. 4 is a typical comparison graph of the relationship between gas concentration and power supply, and the alarm threshold is set in stages according to the corresponding relationship between voltage and smoke (gas) concentration in the graph, mainly the relationship between combustible gas and Co and power supply.
Before the program is run formally, there is a threshold value setting inquiry subprogram. And setting the alarm threshold as the highest alarm threshold, and after the subprogram is inquired for n times, fixing the relevant information condition of the user, fixing the threshold condition and switching to a silent state. If a false positive condition exists later, the user can reset or manually adjust the sensitivity. But the manual threshold does not exceed the automatic minimum threshold.
The limit of the lowest threshold value is to guarantee safety, and false alarm is prevented while safety is guaranteed to the maximum extent. And comprehensively balancing and confirming the lowest threshold value according to the lowest value of the stable response of the sensor range and the range precision. For example, if the minimum value of the sensor range is 0, the determination is made based on the maximum value of the floating value at 0, and if not, the minimum threshold value is determined based on the product of the minimum value of the sensor range and the measurement accuracy. For example, a minimum of 25PPm can be established based on the range of span of 0-500PPm, and the accuracy of the measurement + -5%.
For example:
system set level 1, 2, 3 alarms
Gas concentration 100PPM corresponding to 1-level alarm threshold
Gas concentration 175PPM corresponding to 2-level alarm threshold
Gas concentration 250PPM corresponding to 3-level alarm threshold
After the system is initially installed by a user: the following scenario simulation was performed.
(1) When a user enters a kitchen, if gas or smoke alarm exists, an alarm source inquires whether detection is normal or not, the alarm threshold value is sequentially increased, whether people enter the kitchen or not can be judged through a CCD camera, and the like.
(2) After the infrared temperature sensor responds for a period of time, namely when the cooker works, namely when a user cooks, whether the user adds cooking wine or not is judged, if gas or smoke exists, an alarm is given and inquires whether the detection is normal or not, and an alarm threshold value, a fixed threshold value and the like are sequentially increased.
The threshold value of the environmental temperature data is determined according to the following two conditions:
1. when the ignition stove is not started (judged by infrared temperature data), and the derivative of the infrared temperature data to time is stably changed, the fire is judged to be not fired; if the derivative of the infrared temperature data with respect to time abnormally changes, a misfire is identified.
2. And when the ignition stove is started, determining the range of the ambient temperature according to the ignition time and the temperature of the unopened ignition stove.
Threshold determination of infrared temperature data: 1. whether the kitchen range works or not is qualitatively judged by directly judging the infrared temperature information of the flame. 2. Whether the iron pan is dry-burned or not is judged by directly judging the infrared temperature information of the iron pan.
The scheme judges whether the flame form is abnormal or not by the following method:
the normal state of the flame is mainly a pot state and a non-pot state, and after the flame structure image is processed, the following information can be collected for judgment: flame length, and flame distribution (planar), flame exit angle.
When no pot is available, the state of big fire is as follows: the inner layer and the outer layer of flames are petal-shaped, and the outer ring of flames is slightly inward convergent in appearance.
When no pot is available, the medium fire state is as follows: the outer ring flame extinguishes only the inner ring flame, and the flame shape is similar to that of a big fire.
When no pot is available, the state of small fire is as follows: the flame shape was significantly weaker.
When a pot is available: the petals of the inner and outer ring flames turn outwards.
The normal state, the flame length, the flame distribution area and the emergence angle are all in a range, and the fire condition can be determined by setting the ranges as threshold values.
The multi-sensor adopts a situation-based working mode and a sectional judgment method, firstly, the temperature sensor 11, the smoke sensor 12 and the infrared temperature sensor 13 are utilized to quickly and roughly check, and if a problem exists, the CCD camera 14 is used for carrying out image careful detection, so that the detection comprehensiveness is improved, the detection efficiency and quality are ensured, the processing and running time of an information processing module is shortened, the instantaneity is improved, and the system life is prolonged. The method can also be used for processing tasks by analogy with a computer CPU (central processing unit), running with low power consumption under a normal condition, and running with short-time overclocking under the condition of processing complex programs or multiple tasks.
The display control module 4 is connected to the control module 22 through a communication network, the display control module 4 includes a display area for displaying the processing data of the information processing module 21 and an instruction area for inquiring the operation instruction of the user, and the instruction area includes a favorite recording instruction area and an automatic control instruction area. The display control module 4 has a prompt function, and prompts the user to perform a selection operation when receiving the processing data of the information processing module 21 and requiring to inquire an operation instruction of the user. Such as by being alerted in the form of a whistle or vibration.
If the recording preference instruction is selected, the threshold value changing unit analyzes the processing data of the information processing module 21, and changes the control threshold value according to the analysis result. In this embodiment, as a preferable scheme, the threshold changing unit 213 analyzes the processing data of the information processing module 21 by a neural network analysis method. Specifically, the inputs to the neural network are the flame length, and the flame distribution (area, flame exit angle, user decision, etc.). The output of the neural network is the fitted characteristic range information of the normal flame. The system itself is provided with a fixed range, but since the user may prefer a strong or soft fire, the central point of the above information may deviate from the user's actual situation, leading to an increase in false alarms. Whether the fire condition is met or not is manually intervened, the system automatically learns to adjust the length, the distribution area and the flame emergence angle range of the normal flame, adjusts the habitual operation method of the user, finally fits reasonable flame parameters of the user-used cooking utensils, simultaneously eliminates the parameters of false alarm, and changes (adjusts) the control threshold value according to the analysis result, so that false alarm is reduced. The neural network analysis method is mainly used for confirming parameters of image processing, and whether the flame range, the flame length and the flame incident angle are smaller than a threshold value. The threshold is finally confirmed according to the user intervention state and the long-time acquisition and learning of the flame of the user on the basis of the laboratory threshold, so that the judgment is more accurate, and the image processing is the final judgment and is determined according to the user learning. Other thresholds (smoke concentration data, combustible gas concentration data threshold, ambient temperature data threshold, and infrared temperature data threshold) are set according to laboratory conditions, and can be set strictly.
If the automatic control instruction is selected or no treatment instruction is received within the preset time h, the control module 22 sends an instruction to the air valve closing device 31 to control the air valve to be closed, the gas source is cut off, the fire is prevented from further expanding, the control module 22 simultaneously sends an instruction to the power supply disconnecting device 32 to control the power supply to be disconnected, and the control module 22 also simultaneously sends an instruction to the fire extinguisher control device 33 to start the fire extinguisher 6 to work to extinguish the fire. The fire can be eliminated in the initial stage through the series of emergency measures, and the casualties of people and property caused by the fire can be reduced.
The alarm module 5 is in communication connection with the control module 22 and is used for carrying out automatic alarm reminding when receiving the alarm control signal transmitted by the control module 22. Preferably, the alarm module 5 may be connected to the control module 22 through a CAN bus, or may be connected to the control module 22 through a communication network.
In this embodiment, as a preferable scheme, the display control module 4 is an APP built in the mobile terminal. The operation is convenient for users.
In this embodiment, as a preferred scheme, the mobile terminal is a mobile phone, a tablet computer, an electronic bracelet or other electronic devices. The portable fire alarm device is convenient to carry, and can receive fire information at the first time in any place with a network by using a mobile phone, so that measures can be taken conveniently. This scheme utilizes cell-phone or other mobile terminal, utilizes communication to remind and APP deals with, increases the face of being used, improves the accuracy of handling, practices thrift systematic intelligent cost.
In the present embodiment, the alarm module 5 preferably includes a buzzer and/or a flashing device. The scheme enables the alarm signal sent by the alarm module 5 to be larger in dynamic and static states, and avoids the best time for people to take measures because the alarm signal cannot be found.
