Trend, and tend to higher than 0.5ppm a value stablize and this state duration be more than 10min, then it is assumed that infrared array biography
Sensor may damage or kitchen range not surveying in range in infrared sensor array, then is alarmed in time by alarm module,
I.e. buzzer sounds, LED light goes to abnormality from normal condition and voice alerting unit reminds user to check kitchen range
Whether it is located at infrared sensor array surveying in range, however, it is determined that kitchen range are located at the surveying in range of infrared sensor array,
Then reminding user's infrared sensor array may damage, need the problem of replacing in time.
Situation three when the temperature that infrared sensor array monitors reaches 100 DEG C or more, and is detected by CO sensor
CO concentration also above 0.5ppm, and combustion gas instantaneous flow is close to zero and when the duration is more than 5min, then it is assumed that safety valve
There are failures for the ultrasonic flow detection part of device, can not accurately measure to 5 instantaneous flow of ultrasonic wave channel.At this point,
It is alarmed by alarm module, i.e., buzzer sounds, LED light from normal condition goes to abnormality, voice prompting list
Member reminds user to need timely maintenance relief valve device.
Embodiment 2
It on the basis of example 1, further include the user being connect by public network communication module with fire prevention warning device
Terminal, user terminal can alarm after adding the number of upper fire prevention warning device and relief valve device from fire prevention
The various data detected are obtained at device.The data that data processing module receives can be carried out real-time update and shown by user terminal
Show, and checks alarm and prompt information that data processing module is sent, such as: it can check current kitchen environment temperature, kitchen range
Whether there is kitchen with fiery state, CO concentration, the switch state of valve, combustion gas instantaneous flow size, channel pressure size, people
Situation and user operation records.Meanwhile user terminal can also control the opening and closing of relief valve device, it can also
The time of closed safe valve gear is set, and the service condition for understanding equipment and kitchen convenient for user can control relief valve device.With

Data and environmental parameter.User terminal, which can be performed, requests to check the various data that certain section of monitoring in time arrives to data management system
Deng operation, avoiding all data that will be monitored from being stored in user terminal leads to the problem that memory usage is high, practicability is low, makes
With conveniently.
Embodiment 4
It further include being set to safe 1 outside of valve body, being controlled by conducting wire and valve on the basis of above-described embodiment two
Key a, key b and the voice playing module that module 12 connects.Wherein, key a is individual valve control button, by valve
Control module 12 open motor valve 6 and close between motor valve 6 two operations switching.Key b is used for inquiry system state.
Voice playing module is used to pass through language when detecting that abnormal conditions need to alarm or user carries out inquiry operation by key b
The mode that sound plays informs user.In the present embodiment, voice playing module uses ventional loudspeakers.
When a key is pressed, valve control module 12 obtains low level signal, when unclamping key, valve control module 12
High level signal is obtained, to judge that key-press status is to press or discharge.Specifically, a is pressed the button, is cut when from close valve state
When changing to opening valve state, whether valve control module 12 judges automatically 5 pressure state of current ultrasonic channel in normal model
In enclosing, only 5 pressure of ultrasonic wave channel in the normal range when, just activate to open the movement of motor valve 6, to ensure safety.It presses
When key b, voice playing module is controlled by valve control module 12 and plays current system conditions, for example plays 11 electricity of supplying cell
The system informations such as amount, pressure state, flow status, communications status.It, can when instantaneous flow is less than preset minimum discharge
Gas leakage alarm is prompted by voice playing module.When the pressure that valve control module 12 obtains from press detection sensor 7
When force data is higher than preset upper pressure limit value, pipeline overpressure alarm can be prompted by voice playing module.When valve control
When the pressure data that molding block 12 obtains from press detection sensor 7 is lower than preset low pressure limit value, language can be passed through
Sound playing module prompts pipeline undervoltage warning.
Embodiment 5
On the basis of above-described embodiment two, fire prevention warning device further includes for during the cooking process, calculating and using
The timing unit of kitchen time is left at family, and timing unit is integrated in inside data processing module, and is remembered in data processing module and set
Fixed time threshold is S.In the case that kitchen range are being cooked in kitchen, when detecting no one in kitchen, data processing mould
Block starts automatically is integrated in its internal timing unit, and timing unit starts to calculate the time that user leaves kitchen, in time S
It is interior, if user is not appeared in kitchen once, chip is handled by alarm module and carries out initiative alarming.At timing unit
Under the premise of starting, in time S, if user is again appeared in kitchen, data processing module automatic closing timing list
Member, timing unit stop calculating.If fire prevention warning device is connected with terminal device, it is such as connected with cell phone application, then can be passed through
Cell phone application reminds user to be handled in time.Meanwhile user can also change time threshold S by terminal device.Such as need compared with
In the case where long cooking time, time threshold 30min can be changed to 1h by user.It solves needs and participates in kitchen timing manually
Unlatching, closing, the time setting of device, cannot solve at all because forgetting to close security hidden trouble caused by fire.
