[0083] like Figure 1 As shown, a method for pressure inspection of a heating boiler according to a preferred embodiment of the present application includes:

[0084] S101: Establish a heating boiler pressure monitoring model;

[0085] S102: Preset multiple pressure monitoring points, and generate a boiler pressure evaluation value according to real-time pressure data of the pressure monitoring points and a heating boiler pressure monitoring model;

[0087] Specifically, when generating boiler pressure evaluation values, it includes:

[0088] Preset feedback time nodes and obtain real-time pressure values ​​of all monitoring points according to the feedback time nodes;

[0089] Generate a pressure value sequence A, A = (a1, a2...an), where n is the number of monitoring points;

[0090] Preset safe pressure range;

[0091] Generate the number m of abnormal pressure monitoring points according to the safe pressure range and pressure value series A;

[0092] Generate an initial evaluation value b1 of boiler pressure according to the number m of abnormal pressure monitoring points;

[0096] The boiler pressure evaluation value b is generated according to the correction coefficient e and the initial evaluation value b1, wherein b=e*b1.

[0097] Specifically, the safe pressure range refers to the pressure range of the monitoring point when the boiler is operating normally. When the real-time pressure of the monitoring point is not within the safe pressure range, it means that there is an abnormality at the current monitoring point.

[0098] Specifically, the pressure fluctuation evaluation value refers to the historical pressure fluctuation of the current monitoring point. The more stable the pressure at the monitoring point, the lower the pressure fluctuation evaluation value.

[0099] Specifically, when generating the initial evaluation value b1 of the boiler pressure according to the number m of abnormal pressure monitoring points, it includes:

[0100] A preset pressure abnormality monitoring point number matrix M is set as M(M1, M2, M3, M4), wherein M1 is the preset first pressure abnormality monitoring point number, M2 is the preset second pressure abnormality monitoring point number, M3 is the preset third pressure abnormality monitoring point number, M4 is the preset fourth pressure abnormality monitoring point number, and M1<M2<M3<M4;

[0102] If M1<m<M2, the initial evaluation value b1 is set to the preset first boiler pressure evaluation value B1, that is, b1=B1;

[0103] If M2<m<M3, the initial evaluation value b1 is set to the preset second boiler pressure evaluation value B2, that is, b1=B2;

[0104] If M3<m<M4, the initial evaluation value b1 is set to the preset third boiler pressure evaluation value B3, that is, b1=B3;

[0105] If m>M4, the initial evaluation value b1 is set to the preset fourth boiler pressure evaluation value B4, that is, b1=B4.

[0106] Specifically, a boiler pressure evaluation value matrix may be set according to historical operation data, wherein a higher boiler pressure evaluation value indicates a higher possibility of a current boiler transmission failure.

[0107] It can be understood that in the above embodiment, by establishing a matrix of the number of abnormal pressure monitoring points and a matrix of boiler pressure evaluation values, the boiler pressure is initially evaluated according to the number of abnormal monitoring points, and after subsequent corrections, the real-time pressure condition of the boiler is accurately monitored, thereby eliminating potential failure risks of the heating boiler and ensuring the efficient operation of the heating boiler.

[0113] Obtain the real-time pressure value variance of the monitoring point and set the pressure fluctuation evaluation value c of the monitoring point;

[0114] If F1<f<F2, the pressure fluctuation evaluation value c is set to the preset first pressure fluctuation evaluation value C1, that is, c=C1;

[0115] If F2<f<F3, the pressure fluctuation evaluation value c is set to the preset second pressure fluctuation evaluation value C2, that is, c=C2;

[0116] If F3<f<F4, the pressure fluctuation evaluation value c is set to the preset third pressure fluctuation evaluation value C3, that is, c=C3;

[0117] If f>F4, the pressure fluctuation evaluation value c is set to the preset fourth pressure fluctuation evaluation value C4, that is, c=C4.

[0118] Specifically, a pressure fluctuation evaluation value matrix can be generated based on historical operation data. The larger the variance value, the greater the pressure fluctuation at the current monitoring point, and the larger the corresponding pressure fluctuation evaluation value.

[0119] Specifically, when generating the corrected evaluation value d based on all pressure fluctuation evaluation values, it includes:

[0120] Obtain the pressure fluctuation evaluation values ​​c1, c2…cn of all monitoring points;

[0128] If D2<d<D3, the correction coefficient e is set to the preset second correction coefficient e2, that is, e=e2;

[0129] If D3<d<D4, the correction coefficient e is set to the preset third correction coefficient e3, that is, e=e3;

[0130] If d>D4, the correction coefficient e is set to the preset fourth correction coefficient e4, that is, e=e4.

[0131] Specifically, a longitudinal analysis is performed based on the historical pressure data of each monitoring point to set the correction coefficient and correct the initial boiler pressure evaluation value, so as to dynamically adjust the maintenance instructions, ensure the timeliness of maintenance, eliminate the potential failure risks of the heating boiler in time, and ensure the efficient operation of the heating boiler.

[0132] Specifically, when a boiler maintenance instruction is generated according to the boiler pressure evaluation value, it includes:

[0135] If B2<b<B4, generate a secondary maintenance instruction

[0136] If b>b4, a third-level maintenance instruction is generated.

[0137] Specifically, the first-level maintenance instruction means that maintenance should be carried out according to the regular maintenance plan, while paying attention to monitoring points with abnormal maintenance and monitoring points with higher pressure fluctuation evaluation values. The second-level maintenance instruction means that the heating boiler needs to be maintained on the same day to eliminate the risk of failure in time. The third-level maintenance instruction means that the heating boiler needs to be maintained immediately to avoid failure of the heating boiler.

[0138] In a preferred embodiment of the present application, when the feedback time node is preset, it includes:
