[0041] The combustible gas detection module is used to obtain the real-time data of the combustible gas type and corresponding concentration in the distribution box;

[0042] Smoke detection module, used to obtain real-time data on smoke concentration in the distribution box;

[0043] The central processing unit is used to obtain temperature and humidity prediction data respectively through the preset GM (1,2) model based on the real-time temperature and humidity data inside the distribution box; it is also used to obtain corresponding combustible gas concentration prediction data through the preset GM (1,1) model based on the real-time combustible gas concentration data inside the distribution box;

[0044] A first judgment module is used to refer to the preset combustible gas control information and the preset temperature and humidity interval, based on the combustible gas concentration prediction data and the temperature and humidity prediction data, and according to the preset first judgment method, timely start the early warning module and / or the automatic adjustment module;

[0047] The early warning module is used for early warning; the safety brake module is used for safety braking to protect the internal components of the distribution box.

[0048] In this embodiment, for obtaining temperature prediction data, the real-time temperature data and the real-time humidity data are respectively used as inputs of the GM (1, 2) model, and the temperature prediction data is used as output;

[0049] In this embodiment, for obtaining humidity prediction data, the real-time temperature data and the real-time humidity data are respectively used as inputs of the GM (1, 2) model, and the humidity prediction data is used as output.

[0050] For the GM(1,2) model, it should be noted that the temperature prediction data will be affected by both the temperature real-time data and the humidity real-time data. Similarly, the humidity prediction data will be affected by both the temperature real-time data and the humidity real-time data. Therefore, whether it is to obtain the temperature prediction data or the humidity real-time data, the GM(1,2) model is used, that is, the temperature real-time data and the humidity real-time data are used as the input of the GM(1,2) model. The essence of the GM(1,2) model belongs to the GM(1,n) model. The construction process of the GM(1,n) model is as follows:

[0051] Suppose there are n variables X1, X2, …, X n , each variable has m corresponding time series observations:

[0052] X i (0) =[X i (0) (1),X i (0) (2),…,X i (0) (m),](i=1,2,…,n) (1)

[0053] For each The cumulative generated columns are:

[0054] X i (1) =[X i (1) (1),X i (1) (2),…,X i (1) (m),](i=1,2,…,n) (2)

[0055] Then the differential equation can be established:

[0056]

[0057] Parameter β = (ab2b3…b n ) T , estimated by the least squares method:

[0058]

[0059] in,

[0060]

[0061] Then the GM(1,1) model is:

[0062]

[0063] The prediction model after cumulative reduction is:

[0064]

[0065] In this embodiment, for obtaining the predicted data of the combustible gas concentration, the real-time data of the combustible gas concentration is used as the input of the GM (1,1) model, and the predicted data of the combustible gas concentration is used as the output.

[0066] For the GM (1,1) model, it should be noted that the combustible gas concentration prediction data will not be affected by other factors in this embodiment, so the combustible gas concentration real-time data is used as the input of the GM (1,1) model; the construction process of the GM (1,1) model is as follows:

[0067] Assume that the time series has n observations:

[0068] X (0) =[X (0) (1),X (0) (2),…,X (0) (n)] (9)

[0069] Generate new sequences by accumulation:

[0070] X (1) =[X (1) (1),X (1) (2),…,X (1) (n)] (10)

[0071] Order Z (1) For X (1) Generate a sequence of adjacent means of :

[0072] Z (1) =[Z (1)(2),Z (1) (3),…,Z (1) (n)] (11)

[0073] Z (1) (k) = 0.5 (X (1) (k-1)+X (1) (k)) (12)

[0074] Then the grey differential equation model of GM(1,1) is:

[0075] X (0) (k)+aZ (1) (k) = b (13)

[0076] In the formula, a is called the development gray number; b is called the endogenous control gray number.

[0077] set up is the parameter vector to be estimated

[0078]

[0079] The least squares method can be used to solve it, and we get

[0080]

[0081]

[0082]

[0083] Equations (16) and (17) are called differential equations.

[0084]

[0085] is the grey differential equation X (0) (k)+aZ (1) The whitening equation of (k)=b is also called the shadow equation.

[0086] 1) The solution of the whitening equation is also called the time response function, which is:

[0087]

[0088] 2) GM(1,1) grey differential equation X (0) (k)+aZ (1) The time response sequence of (k) = b is:

[0089]

[0090] 3) Take X (1) (0) = X (0) (1) Yes

[0096] In this embodiment, it should be noted that the first determination method includes:

[0097] When the humidity prediction data exceeds the preset humidity range, it indicates that the humidity in the distribution box may be too high in the future, and the humidity needs to be lowered in advance, and then the heating and exhaust function mode of the automatic adjustment module is started until the humidity prediction data falls back to the preset humidity range;

[0098] When the temperature prediction data exceeds the preset temperature range, and the combustible gas concentration prediction data does not reach the combustion concentration, it indicates that the temperature in the distribution box may be too high in the future, and the temperature needs to be lowered in advance, and then the exhaust function mode of the automatic adjustment module is started until the temperature prediction data falls back to the preset temperature range;

[0099] When the predicted combustible gas concentration reaches the corresponding combustion concentration, and the predicted temperature does not reach the corresponding ignition point of the combustible gas, it indicates that the combustible gas concentration may be too high in the distribution box in the future, and the combustible gas needs to be exhausted and evacuated in advance, and then the exhaust function mode of the automatic adjustment module is started until the predicted combustible gas concentration is lower than the corresponding combustion concentration;

[0101] In this embodiment, it should be noted that the second determination method includes:

[0102] When the real-time data of smoke density exceeds the preset range of smoke density, and the real-time data of temperature does not show a continuous upward trend, it means that smoke from the outside has escaped into the distribution box, and it is not caused by combustion in the distribution box. It is necessary to exhaust and evacuate the smoke in the distribution box, and then start the exhaust function mode of the automatic adjustment module until the real-time data of smoke density falls back to the preset range of smoke density;

[0103] When the real-time data of smoke concentration exceeds the preset range of smoke concentration and the real-time data of temperature shows a continuous upward trend, it indicates that there is combustion in the distribution box and smoke is caused. At this time, a major accident has occurred and emergency braking is required to prevent the spread of combustion. The smoke in the distribution box needs to be exhausted and evacuated, and then the insurance brake module is activated, and an important accident warning is issued to remind relevant personnel. At the same time, the exhaust function mode of the automatic adjustment module is started until the real-time data of smoke concentration falls back to the preset range of smoke concentration.
