[0067] Construct a judgment rule for the monitoring and early warning risk level.

[0068] Based on this, this invention establishes a set of scientific risk assessment methods by comprehensively considering the inherent risks (equipment, process, personnel) and dynamic risks (real-time monitoring, management behavior) of enterprises, and can accurately evaluate the safety production risk level of enterprises.

[0069] Please refer to Figure 2 , Figure 2 which is Figure 1 the sub-step flowchart of step S4 in Figure 2 As shown, the early warning step S4 includes:

[0070] Inherent risk correction coefficient acquisition step S41: Calculate the inherent risk correction coefficient based on the inherent risk indexes through the scoring rule of the inherent risk correction early warning value;

[0076] Perform normalization processing on the inherent risk warning value through a linear proportion conversion algorithm to obtain the corresponding inherent risk correction coefficient.

[0077] Specifically, the inherent risk correction coefficient α R Consists of influencing factors such as the number of casting wells, the type of casting well traction and lifting, the type of casting furnace, and the number of on-site operators. The specific inherent risk indicators include: the number of casting wells, the type of casting well traction and lifting, the type of casting furnace, the number of casting personnel in a single shift, the installation date of the casting well, the certification status of the main person in charge, and the certification status of the safety management personnel.

[0081] In the formula:

[0082] G - Inherent risk warning value;

[0083] ai - The inherent risk level of the i-th item;

[0084] b i ——The inherent risk coefficient of the i-th item.

[0086] Inherent risk level and inherent risk coefficient assignment table:

[0087]

[0088]

[0089] According to the process conditions, referring to the above table, multiply the inherent risk level a of each dimension i and the inherent risk coefficient b i and sum them up to obtain the inherent risk warning value G. Perform normalization processing on the score of the inherent risk warning value G using the "linear proportional conversion algorithm" to convert it into the corresponding inherent risk correction coefficient α R , and the rules are as follows:

[0091] Inherent risk warning value G <![CDATA[Inherent risk correction factor α R > 20≤G≤64 <![CDATA[1 ≤ α R ≤ 5]]>

[0092] The present invention automatically adjusts the inherent risk weights according to the enterprise process characteristics (such as winch traction, hydraulic traction), improves the adaptability of the model, and flexibly adjusts the monitoring parameters and warning thresholds to meet the needs of different enterprises.

[0093] Please refer to Figure 3 , Figure 3 for Figure 2 the step flow chart of step S42 in Figure 3 . As shown in

[0094] Step S421 for obtaining the warning value of the main monitoring parameters of the deep-well casting system: After obtaining the first single-index operation risk warning value based on some of the operation risk indicators through the scoring rules of the single-index operation risk warning value, calculate the warning value of the main monitoring parameters of the deep-well casting system;

[0096] Step S423 for calculating the dynamic risk warning index: After obtaining the dynamic risk warning value based on the warning value of the main monitoring parameters of the deep-well casting system and the warning value of the daily management elements, perform normalization processing on the dynamic risk warning value to obtain the dynamic risk warning index.

[0097] Among them, the scoring rules for constructing the warning values of single-item indicator operation risks include: the first single-item indicator operation risk warning value scoring rule and the second single-item indicator operation risk warning value scoring rule; in the step of obtaining the warning values of the main monitoring parameters of the deep-well casting system, the first single-item indicator operation risk warning value is obtained based on some of the operation risk indicators through the first single-item indicator operation risk warning value scoring rule; in the step of obtaining the warning values of the daily management elements, the second single-item indicator operation risk warning value is obtained based on another part of the operation risk indicators through the second single-item indicator operation risk warning value scoring rule.

[0098] Specifically, the dynamic risk warning index T R is determined by the operating states of the deep-well casting system and its associated processes, mainly involving the alarm triggering and elimination of monitoring parameters, as well as the components of the enterprise's daily management elements. The dynamic risk warning index T R is obtained by normalizing the dynamic risk warning value T d to get.

[0099] The dynamic risk warning value T d has the following calculation formula:

[0100] Td = Talarm + Tg

[0101] In the formula:

[0102] T d —— The dynamic risk warning value;

[0103] T alarm —— The warning values of the main monitoring parameters of the deep-well casting system;

[0104] T g —— The warning values of the enterprise's daily management elements.

[0105] In step S421, the warning value T alarm of the main monitoring parameters of the deep-well casting system is composed of influencing factors such as signal access situation, maximum alarm duration, and average alarm duration per point. In this embodiment, specifically, it is signal access, maximum alarm duration, average alarm frequency per point, repeated alarm frequency per point, and simultaneous alarm frequency at multiple points. In the step of obtaining the warning values of the main monitoring parameters of the deep-well casting system, the first single-item indicator operation risk warning value is obtained based on signal access, maximum alarm duration, average alarm frequency per point, repeated alarm frequency per point, and simultaneous alarm frequency at multiple points through the first single-item indicator operation risk warning value scoring rule.

[0106] The calculation formula for the warning value T alarm of the main monitoring parameters is:

[0108] In the formula:

[0109] T alarm —— Early warning value of the main monitoring parameters of the deep well casting system;

[0110] T b —— Early warning value of the operation risk of a single index.

[0111] Scoring rules for the early warning value of the operation risk of the first single index:

[0112]

[0113]

[0114] Alarm events are divided into key parameter items and hierarchical alarm items. Among them, the key parameter items are the index items with a higher risk coefficient. The hierarchical alarm items have different set times according to different monitoring and early warning indicators. See the following table for details.

[0116]

[0117]

[0118] Decision table for hierarchical alarm items of "alarm events"

[0119]

[0120]

[0121] Among them, in this embodiment, the hierarchical alarm of "alarm events" is used for internal disposal within the enterprise. The secondary alarm is fed back to the enterprise workshop operators and management personnel, and the primary alarm is fed back to the enterprise's main person in charge and safety director. The present invention issues early warning information in real time according to the risk assessment results, reminding the enterprise to take measures in a timely manner. Different triggering logics and alarm cancellation conditions are set according to the alarm types (direct judgment items, key early warning items, hierarchical alarm items) to avoid false alarms.

[0122] In step S422, the early warning value T of the enterprise's daily management elements g is composed of influencing factors such as the wire rope inspection period, wire rope replacement period, and video monitoring operation status. In this embodiment, specifically, it is the wire rope inspection period, wire rope replacement period, and video monitoring operation status. In the step of obtaining the early warning value of the daily management elements, the second single index operation risk early warning value is obtained based on the wire rope inspection period, wire rope replacement period, and video monitoring operation status through the second single index operation risk early warning value scoring rule.

[0123] The early warning value T of the enterprise's daily management elementsg The calculation formula is as follows:

[0124]

[0125] In the formula:

[0126] T g —— Early warning value of enterprise daily management elements;

[0127] T f —— Early warning value of single - index operation risk.

[0128] Scoring rules for the second single - index operation risk early warning value:

[0129]

[0130] In the dynamic risk early warning index calculation step S423, the dynamic risk early warning value T d is normalized and converted into the corresponding dynamic risk early warning index T R , and the conversion relationship is as follows:

[0131] <![CDATA[Dynamic risk warning value T d > <![CDATA[Dynamic risk warning index T R > <![CDATA[0≤T d ≤30]]> <![CDATA[0 ≤ T R ≤ 1]]> <![CDATA[30 < T d ≤ 60]]> <![CDATA[1 < T R ≤ 2]]> <![CDATA[60 < T d ≤ 90]]> <![CDATA[2 < T R ≤ 3]]> <![CDATA[90 < T d ≤ 120]]> <![CDATA[3 < T R ≤ 4]]> <![CDATA[120 < T d ≤ 260]]> <![CDATA[4 < T R ≤ 5]]>

[0133] Obtaining the enterprise monitoring and early warning risk level index through the inherent risk correction coefficient and the dynamic risk early warning index;

[0134] Obtaining the monitoring and early warning risk level corresponding to the enterprise monitoring and early warning risk level index according to the judgment rules of the monitoring and early warning risk level for the enterprise monitoring and early warning risk level index;

[0135] Among them, the early warning result includes the enterprise monitoring and early warning risk level index and the monitoring and early warning risk level.

[0136] Specifically, the calculation formula of the enterprise monitoring and early warning risk level index is:

[0137] R = α R ×T R ;

[0138] In the formula:

[0139] R——Enterprise monitoring and early warning risk level index, R ∈ [0, 25];

[0140] α R ——Inherent risk correction coefficient, α R ∈ [1, 5];

[0141] T R ——Dynamic risk early warning index, TR ∈ [0, 5].

[0142] Judgment rules for monitoring and early warning risk levels:

[0143] Enterprise monitoring and warning level index R Monitoring and warning risk level 9＜R≤25 Level I risk 4＜R≤9 Level II risk 1＜R≤4 Level III risk 0≤R≤1 Level IV risk

[0144] Note: The monitoring and early warning risk level I is the highest, and the level IV is the lowest.
