Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise stated, the meaning of "a plurality" is two or more.

[0020] In the description of the present application, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0021] Such as Figure 1As shown in the figure, an alarm monitoring system for the safe operation of a high-voltage switchgear in a preferred embodiment of the present application includes: A central control unit for setting multiple monitoring points according to device parameters; A monitoring unit including multiple monitoring sub-modules, and the monitoring sub-modules are arranged at each monitoring point; An alarm unit for generating an alarm signal; The central control unit includes: A first processing module for establishing a risk early warning model; A second processing module for setting the monitoring strategy of the monitoring unit and obtaining monitoring data packets according to the monitoring strategy; The second processing module is also used for judging whether to generate a warning instruction according to the monitoring data packet; A first control module for setting the working parameters of the alarm unit according to the warning instruction.

[0022] Specifically, the monitoring unit is preferably various sensors and image acquisition devices, and the specific devices selected for the corresponding monitoring sub-modules are different according to the different data types required to be collected at each monitoring point.

[0023] Specifically, the alarm unit includes multiple alarm sub-modules and can perform sound alarms and light alarms.

[0024] Specifically, the first processing module is also used for: Establishing a behavior sub-model based on historical monitoring data; Traversing the identity parameters of all personnel; Establishing a sequence of staff A, A = (a1, a2... a i …a n ), where a i is the i-th staff member; n is the number of staff members; Setting a primary risk sub-model according to the sequence of staff A and the behavior sub-model; Setting multiple risk characteristic indicators according to historical monitoring data; Generating a secondary risk sub-model according to all risk characteristic indicators; Constructing a risk early warning model according to the primary risk sub-model and the secondary risk sub-model.

[0025] Specifically, the historical monitoring data refers to the historical operation data and accident data of the high-voltage switchgear recorded.

[0026] Specifically, the primary risk sub-model mainly identifies and analyzes the operation behavior of staff by obtaining monitoring image data and generates corresponding behavior risk values.

[0027] Specifically, the secondary risk sub-model mainly generates corresponding state risk values by analyzing the real-time operation parameters and environmental parameters of the high-voltage switchgear (for example, no water accumulation, humidity, sundries or flammable substances around the switchgear, ambient temperature, humidity, the switchgear is in a power-off state, no abnormal sounds (such as discharge, arc sound), no smoke or sparks, motor overload, refusal to operate, etc.).

[0028] Specifically, when setting the primary risk sub-model, it includes: Set a i as the target staff member in sequence according to staff member A; Generate a training data packet for the target staff member based on historical monitoring data; Generate a compensation sub-strategy for the target staff member based on the training data packet; Generate compensation sub-strategies for each staff member in sequence; Establish a sequence of compensation sub-strategies P, P = (p1, p2…p i …p n ), where p i is the compensation sub-strategy for the i-th staff member; n is the number of staff members; Set the primary risk sub-model according to the sequence of compensation sub-strategies P and the behavior sub-model.

[0029] Specifically, set multiple behavioral risk indicators according to the behavior sub-model. It includes but is not limited to multiple parameters such as whether the operation sequence is correct, whether non-operation areas are touched, and whether there are any violation behaviors.

[0030] Specifically, the training data packet includes the historical operation parameters of the target staff member. By analyzing the data in the training data packet, the compensation sub-strategy of the target staff member is set to achieve dynamic adjustment of the safety thresholds for each behavioral risk indicator, improving the early warning efficiency for operation risks.

[0031] Specifically, the compensation sub-strategy includes compensation coefficients for the safety thresholds of each behavioral risk indicator. The greater the probability of operation risks occurring during the historical operation of the staff member, the smaller the corresponding compensation coefficient, and the value range of all compensation coefficients is between zero and one.

[0032] It can be understood that in the above embodiments, by analyzing the historical behaviors of each staff member, corresponding compensation strategies are set, thereby improving the targeted monitoring of each staff member, enhancing the identification efficiency of risk behaviors, and preventing accidents such as misoperations, electric shocks, and arc injuries.

[0033] In the preferred embodiment of the embodiment of the present application, the second processing module further includes: Establish a sequence of monitoring points B, B = (b1, b2…b i …bm ), where b i is the i-th monitoring point; m is the number of monitoring points; Determine whether there is an operation plan; If there is, the second processing module generates a primary monitoring strategy; If not, the second processing module generates a secondary monitoring strategy.

[0034] Specifically, the operation plan refers to whether the high-voltage switchgear needs to be operated at the current time node.

[0035] Specifically, the secondary monitoring strategy includes: Establish a primary monitoring point sequence B1 according to the position parameters of each monitoring point, B1 = (b 11 , b 12 …b 1i …b 1m1 ), where b 1i is the i-th primary monitoring point; m1 is the number of primary monitoring points; Set the primary working parameters of the monitoring sub-module corresponding to each primary monitoring point.

[0036] Specifically, the primary monitoring point is the induction point set in front of each high-voltage switchgear.

[0037] Specifically, the primary working parameter means that when a person stays in front of the switchgear for 5 seconds, the name and number of the switchgear are alarmed by sound, and the operating state or standby state of the switchgear, and the live conditions of the static contacts at the upper and lower ports of the switchgear are described and warned.

[0038] Specifically, the primary monitoring strategy includes: Obtain the operation cycle and operation content according to the operation plan; Set the monitoring cycle according to the operation cycle, and multiple feedback time nodes are included in the monitoring cycle; Set the end time node of each time interval as the feedback time node; Generate the associated evaluation value with each monitoring point according to the operation content; Establish an associated evaluation value sequence W, W = (w1, w2…w i …w m ), where w i is the associated evaluation value of the operation content and the i-th monitoring point; m is the number of monitoring points; Preset the associated evaluation value threshold W1; If w i > W1, set the i-th monitoring point as the associated monitoring point; Obtain the monitoring data packets of each associated monitoring point according to the preset feedback time node.

[0039] Specifically, according to the operation content, determine the position points to be operated, and determine whether each monitoring point can collect valid data. If valid data can be collected, it is an associated monitoring point.

[0040] It can be understood that in the above embodiments, by dynamically adjusting the working parameters of each monitoring point, while ensuring the monitoring efficiency, the overall operation and maintenance cost is reduced.

[0041] In the preferred embodiment of the present application, when determining whether to generate a warning instruction according to the monitoring data packet, it includes: Obtain the monitoring data packets of all associated monitoring points at the current feedback time node; Generate a behavior data packet and a feature parameter packet according to the preprocessing result; Generate a behavior risk value f1 at the current feedback time node according to the first-level risk sub-model and the behavior data packet; Generate a state risk value f2 at the current feedback time node according to the second-level risk sub-model and the feature data packet; Generate the current risk warning value c according to the behavior risk value f and the state risk value d; Preset a risk warning value threshold C1; If c > C1, a first-level warning instruction is generated at the current feedback time node.

[0042] Specifically, the risk warning value threshold can be set according to historical parameters.

[0043] Specifically, the first-level warning instruction means that there is a safety risk in the current high-voltage switch cabinet, and corresponding voice alarm signals and light alarm signals need to be generated in time through the alarm unit to remind relevant staff and avoid personal injury accidents.

[0044] Specifically, when generating the behavior risk value f at the current feedback time node, it includes: Generate a personnel feature packet according to the monitoring data packets of all associated points; Set a first-level compensation strategy according to the personnel feature packet; f = e1 × Q1 × η i × Y1(i) × (k i - k' i ) + e2 × Q2 × η i × Y1(i) × (k i - g i × k' i ); Wherein, e1 is a preset first weight coefficient; e2 is a preset second weight coefficient; Q1 is a preset first fixed coefficient; Q2 is a preset second fixed coefficient; θ1 is the number of behavior risk indicators; η iis the influencing factor of the i-th behavioral risk indicator; k i is the real-time reference value of the i-th behavioral risk indicator at the current feedback time node; k' i is the standard reference value of the i-th behavioral risk indicator; Y1(i) is the selection coefficient; if (k i - k' i ) > 0, Y1(i) = 1; if (k i - k' i ) < 0, Y1(i) = 0; g i is the correction coefficient for setting the i-th behavioral risk indicator based on the first-level compensation strategy.

[0045] Specifically, all parameters in the model are normalized by presetting the first fixed coefficient and the second fixed coefficient, so that each parameter in the model is within the same value range.

[0046] Specifically, the influencing factor of each behavioral risk indicator can be set according to the corresponding potential possibility of operational risk occurrence. The greater the potential possibility, the greater the corresponding influencing factor.

[0047] Specifically, when generating the state risk value d at the current feedback time node, it includes: d = e3 × Q3 × βi × Y2(i) × (d i - d' i ) 2 + e4 × Q4 × j i × h i ; Among them, e3 is the preset third weight coefficient; e4 is the preset fourth weight coefficient; Q3 is the preset third fixed coefficient; Q4 is the preset fourth fixed coefficient; is the number of risk characteristic indicators; β i is the influencing factor of the i-th risk characteristic indicator; d i is the reference value of the i-th risk characteristic indicator at the current feedback time node; d' i is the safety threshold of the i-th risk characteristic indicator; Y2(i) is the selection coefficient; if (d i - d' i ) > 0, Y2(i) = 1; if (d i - d' i ) < 0, Y2(i) = 0; is the number of historical evaluation indicators; j i is the influencing factor of the i-th historical evaluation indicator; hi is the reference value of the i-th historical evaluation indicator at the current feedback time node.

[0048] Specifically, the influence factors of each risk characteristic index are set according to their influence degree on the safe operation of the switchgear. The greater the influence degree, the greater the corresponding influence factor.

[0049] Specifically, the risk characteristic indicators include, but are not limited to, no water accumulation, dampness, sundries or flammable substances around the switchgear, ambient temperature, humidity, the switchgear being in a power-off state, no abnormal sounds (such as discharge, arc sounds), the presence or absence of smoke and sparks, parameters such as motor overload and refusal to operate. By quantifying each risk characteristic indicator, all-round analysis, monitoring and timely warning of electrical, mechanical and environmental risks during the operation process are realized.

[0050] Specifically, all parameters in the model are normalized by presetting a third fixed coefficient and a fourth fixed coefficient, so that each parameter in the model is within the same value range.

[0051] According to the first concept of this application, by establishing a multi-angle monitoring and alarm reminder network, the operation process of each staff member is comprehensively monitored in a timely manner. Combining the comprehensive analysis results of personnel behavior and risk characteristic indicators, electrical, mechanical and environmental risks during the operation process are warned in a timely manner to ensure personnel safety.

[0052] According to the second concept of this application, by analyzing the historical behaviors of each staff member, corresponding compensation strategies are set, so as to improve the targeted monitoring of each staff member, improve the recognition efficiency of risk behaviors, and prevent accidents such as misoperation, electric shock and arc injury.

[0053] The above are only the preferred embodiments of this application. It should be noted that for those of ordinary skill in the art of this technology, without departing from the technical principle of this application, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of this application.
