refers to a fire of solid matter, which is generally organic in nature and generally produces a burning ember when burned; such as fire, wood, coal, cotton, wool, hemp, paper, etc.
Liquid or meltable solid matter fire: such as kerosene, gasoline, diesel oil, crude oil, methanol, ethanol, asphalt, paraffin and the like.
Gas fire: such as coal gas, natural gas, methane, ethane, propane, hydrogen, etc.
Metal fire: such as potassium, sodium, magnesium, aluminum magnesium alloy and the like.
Live fire: the object is burnt in a charged manner.
The cooking objects in the cooking utensil, such as animal and vegetable grease, are in fire.
In recent years, the index of fire disaster gradually rises, and after a fire disaster happens on some high floors, the fire disaster rescue is delayed due to the fact that the alarm cannot be given for the first time, so that the disastrous effect is caused; in many cases, people are in a confused state of mind once a fire breaks out, and the people want to escape, so that the people are easy to have a trample event in a large-scale place.
Nowadays, social economy develops rapidly, people's standard of living is also higher and higher more and more, and when various buildings were under construction, some smog inductive head, heat energy inductive head etc. had also been installed to mandatory, but these equipment all are on-the-spot small range's operation, and when faced big conflagration, the effect was very little.
When a fire occurs, there are generally electrically related connecting wires or equipment around the fire, and since people are in a hurry and have difficulty in clearly cutting off the power of county officers, the subsequent fire continues, and the continuous electric leakage causes a larger fire.
At present, in the mobile internet market, a mobile phone APP occupies a half-wall river mountain by virtue of various advantages of low price, accuracy, interactivity, super-strong user stickiness and the like. At present, most enterprises or products related to the internet have own mobile phone APPs, and it has become a trend of the market to have own specialized mobile phone APPs.
Therefore, the fire alarm should be made from multiple directions.

For convenience of explanation, the value monitored at time t is referred to as s (t), and the upper and lower bounds of the monitored value are sup and inf, respectively. the expected value monitored at time t is μ (t).
Theory 1 if x is [0,1]]And its desired value E x]Mu, then forThe following formula holds
E[exh]≤ehμ+1-μ
It proves that the order f (x) exhTwo of itThe derivative of the order is f' (x) ═ h2ehx. It can be seen that for any non-zero h, f' (x) > 0, so f (x) is at [0,1 [, ]]Within the range of β ∈ [0,1]]At a time there is
f(βx1+(1-β)x2)≤βf(x1)+(1-β)f(x2)
Since x is [0,1], it is known that
ehx＝f(x)＝f((1-x)×0+x×1)≤(1-x)e0+xeh
To sum up to get
E[ehx]≤E[(1-x)+xeh]＝ehμ+1-μ
Theorem 1 makes E [ s (t) ] ═ mu (t), if mu (t) < α, then there are

Pr[x(t)≥γ]＝Pr[ex(t)h≥eγh]≤e-γhE[ex(t)h]
From introduction 1 can be obtained
From the above two equations, it can be known that any h ∈ (0, ∞), and the following equation holds
To obtain Pr [ s (t) ≥ α]A tight upper bound, requiring the removal of the optimum value h*So that
This is true. Order toThen
When y' (h)*) Obtained when the value is 0
Due to the fact thatThus, it is possible to provideTherefore, it is not only easy to useh*And the Markov inequality condition is satisfied when the value is more than 0. From the above, it can be seen that when h > h*Y (h) is a monotonically increasing function; when h is less than h*And y (h) is a monotone decreasing function. Thus, when h is h*When y (h) takes a minimum value, then it can be obtained
Order to
Wherein x1,x2E (0,1) can be obtained
According to the above two formulas, there areDue to the fact thatThen λ > 0 is present so that α ═ μ (t) + sup λ holds, and soIn view of the above, it is desirable to provide,therefore, inference 1 is drawn according to theorem 1.
Inference 1 when μ (t) < α, at the same timeWhen, i.e. Pr [ s (t) ≧ α]τ is not greater, then the system does not send an alarm.
Theorem 2 let E [ s (t) ] - μ (t), if μ (t) > α, then
Wherein,
proof theorem 2 is similar to proof theorem 1, and some processes are not repeated, namely, αAlso have
Let γ be α/sup, let γ < 1. from the Markov inequality, for any h ∈ (-infinity, 0), we can get
Pr[x(t)≤γ]＝Pr[ex(t)h≥eλh]≤e-λhE[ex(t)h]
According to introduction 1Therefore, for any h ∈ (— ∞,0), the following equation holds
Likewise, h*Need to take the optimum value toTaking the minimum value. Order to
Then when y' (h)*) When equal to 0, can obtain
Due to the fact thatThus, it is possible to provideSo h*< 0 satisfies the Markov inequality condition. When h is more than h*Y (h) is a monotonically increasing function; when h is less than h*And y (h) is a monotone decreasing function. Thus, when h is h*When y (h) takes a minimum value, then it can be obtained
Due to the fact thatThen λ > 0 is present so that α ═ μ (t) -sup λ holds, therefore,to sum up, obtainTherefore, inference 2 is drawn according to theorem 2.
Inference 2 when μ (t) > α, at the same timeWhen, i.e. Pr [ s (t) > α]τ, the system will send an alarm.
In addition to the two cases of inference 1 and inference 2, there are three other main cases, the first is μ (t) < α,i.e. Pr [ s (t) ≥ α]The second is μ (t) > α,i.e. Pr [ s (t) > α]< tau, neither of which cases can discriminate Pr [ s (t) ≧ α]The third is the situation that mu (t) is α, which can cause the estimation method of the tail probability boundary to be invalid and cannot be distinguished specifically, so that the system still adopts a negative strategy under the situation and does not give an alarm.
The specific implementation mode utilizes a multi-azimuth data acquisition technology, information is fed back to the fire-fighting general control center through budget and data conversion, and the fire-fighting general control center takes corresponding processing measures according to the information; in the aspect of data acquisition, fuse the data synthesis of multiple equipment sensor, the accuracy of data has been improved, through stable and using extensive network transmission data down, interim emergency treatment targets in place, whether the main control center of fire control chooses to play that corresponding control unit according to data analysis back, if peripheral early warning, nearby fire control, national grid or first aid center etc. remove the APP terminal also can selective start shower early warning and first aid center simultaneously, help alleviating the situation of conflagration, reduce the coverage of conflagration, reduce the loss.
By adopting the structure, the fire remote monitoring and processing control system has the beneficial effects that the fire remote monitoring and processing control system can meet the data communication requirement of fire alarms, compared with the traditional wired monitoring, the wireless monitoring can greatly reduce the installation cost and the maintenance cost, mass data generated in the monitoring process can be stored and called, compared with the traditional hardware server, the fire remote monitoring and processing control system has the advantages of convenience and rapidness in construction, simplicity and high efficiency in management, safety and reliability in data storage and the like, the development, operation and maintenance difficulty of the server is well reduced, the operation cost is reduced, the fire monitoring mode is enriched by using the mobile phone APP, the fire situation can be more conveniently known by supervisors in real time, a 3 sigma criterion algorithm is introduced as a data acquisition algorithm, and a (α, tau) dual-threshold monitoring algorithm is introduced as an early warning algorithm, so that the anti-jamming capability of the system can be well improved, and the reliability of the system is.
