It generates mechanical energy through a diesel engine and then converts the mechanical energy into electrical energy through a generator. As an important backup power source and independent power supply device, a diesel generator plays an irreplaceable role in power supply.

[0003] A diesel generator control system and a diesel generator are disclosed in a Chinese invention patent with publication number CN114810401A. The technical solution of the invention controls the injection amount of the oil pump in the diesel engine to achieve speed regulation. By adjusting the speed, the working temperature in the diesel engine is adjusted to avoid the temperature in the diesel engine being too high, which leads to a decrease in the service life of the diesel generator.

[0004] However, in the actual application of the above-mentioned technical solution, it is difficult to conduct a progressive and reasonable analysis and timely warning of the parameter control performance, combustible emission status, cooling performance and wear degree of the diesel generator, and it is impossible to achieve comprehensive monitoring and control of the diesel generator, which is not conducive to ensuring the safe and stable operation of the diesel generator and improving its energy-saving effect;

[0005] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0006] The purpose of the present invention is to provide an intelligent diesel generator operation control system based on high efficiency and energy saving, which solves the problem that the prior art is difficult to conduct progressive and reasonable analysis and timely warning of the parameter control performance, combustible emission conditions, cooling performance and wear degree of the diesel generator, and cannot achieve comprehensive monitoring and control of the diesel generator, which is not conducive to ensuring the safe and stable operation of the diesel generator and improving its energy-saving effect.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] The intelligent diesel generator operation control system based on high efficiency and energy saving includes a parameter control analysis module, an emission monitoring feedback module, a cooling operation judgment module, a wear impact assessment module and a management terminal; the parameter control analysis module analyzes the parameter control performance during the operation of the diesel generator, and sends the generator parameter control alarm signal to the management terminal when it generates the generator parameter control alarm signal, and sends the generator parameter control qualified signal to the emission monitoring feedback module when it generates the generator parameter control qualified signal;

[0009] The emission monitoring feedback module monitors the exhaust gas of the diesel generator, analyzes the emission status of the diesel generator when receiving the qualified generator control parameters, and generates an emission flammability alarm signal or an emission flammability qualified signal accordingly. When the emission flammability alarm signal is generated, it is sent to the management terminal, and when the emission flammability qualified signal is generated, it is sent to the cooling operation judgment module;

[0010] When receiving the emission and flammability qualified signal, the cooling operation judgment module will analyze the heat dissipation and cooling performance of the diesel generator, and generate a cooling alarm signal or a cooling qualified signal accordingly. When the cooling alarm signal is generated, it will be sent to the user terminal, and when the cooling qualified signal is generated, it will be sent to the wear impact assessment module; when receiving the cooling qualified signal, the wear impact assessment module will analyze the wear risks of the diesel generator, generate a wear risk signal or a wear controllable signal through analysis, and send it to the user terminal when the wear risk signal is generated; the management terminal will issue an early warning when receiving the generator parameter control alarm signal, emission flammability alarm signal, cooling alarm signal or wear risk signal.

[0011] Furthermore, the specific analysis process of the parameter control analysis module is as follows:

[0012] Monitor the mechanical parameters, electrical parameters and fuel system parameters of the diesel generator, collect the test data of each parameter, and compare the test data with the corresponding preset data requirements. If the test data does not meet the corresponding preset data requirements, it is judged that the corresponding parameter is in a poor control state;

[0013] The total duration and number of occurrences of the corresponding parameter in the poor control state per unit time are marked as the total poor control time value and the poor control frequency value, respectively. The total poor control time value and the poor control frequency value are weightedly summed to obtain the control characteristic value of the corresponding parameter. The control characteristic value is numerically compared with the corresponding preset control characteristic threshold. If the control characteristic value exceeds the corresponding preset control characteristic threshold, the control judgment symbol ZY-1 is assigned to the corresponding parameter. If there is a parameter assigned with the control judgment symbol ZY-1 per unit time, a generator parameter control alarm signal is generated.

[0014] Furthermore, if there is no parameter assigned with the control judgment symbol ZY-1 within a unit time, the ratio of the control characteristic value of the corresponding parameter to the corresponding preset control characteristic threshold is marked as the control risk value, and the control risk values ​​of all operating parameters that need to be monitored and controlled during the operation of the diesel generator are averaged to obtain a comprehensive evaluation value, and the comprehensive evaluation value is numerically compared with the preset comprehensive evaluation threshold. If the comprehensive evaluation value exceeds the preset comprehensive evaluation threshold, a generator parameter control alarm signal is generated; if the comprehensive evaluation value does not exceed the preset comprehensive evaluation threshold, a generator parameter control qualified signal is generated.

[0015] Furthermore, the specific analysis process of the emission monitoring feedback module is as follows:

[0016] The types of combustibles that need to be monitored in the exhaust gas of the diesel generator are obtained, the concentrations of various types of combustibles in the exhaust gas are collected, and each type of combustible is set in advance to correspond to a set of preset calorific value coefficients, and the concentration of the corresponding type of combustible is multiplied by the corresponding preset calorific value coefficient to obtain the combustible characteristic value, and the combustible characteristic values ​​of all types of combustibles that need to be monitored are summed up to obtain the combustible assessment value;

[0017] Obtain the duration of occurrence of the combustibility assessment value exceeding the preset combustibility assessment threshold value per unit time and mark it as the exhaust gas combustibility time value, compare the exhaust gas combustibility time value with the preset exhaust gas combustibility time threshold, and generate an exhaust combustibility alarm signal if the exhaust gas combustibility time value exceeds the preset exhaust gas combustibility time threshold;

[0018] If the exhaust gas flammable condition value does not exceed the preset exhaust gas flammable condition threshold, a flammable set is established for all flammable evaluation values ​​within a unit time, and the maximum value and average value in the flammable set are marked as the flammable high amplitude value and the flammable performance value, respectively; the emission flammable monitoring value is obtained by weighted summing up the exhaust gas flammable condition value, the flammable high amplitude value and the flammable performance value, and the emission flammable monitoring value is numerically compared with the preset emission flammable monitoring threshold. If the emission flammable monitoring value exceeds the preset emission flammable monitoring threshold, an emission flammability alarm signal is generated; if the emission flammable monitoring value does not exceed the preset emission flammable monitoring threshold, an emission flammability qualified signal is generated.

[0019] Furthermore, the specific analysis process of the cooling operation judgment module is as follows:

[0020] The wind speed of the cooling fan in the diesel generator is collected and the difference between the wind speed and the set standard wind speed is calculated and the absolute value is taken to obtain the wind cooling detection value, and the liquid cooling detection value is obtained by liquid cooling tracking analysis, and the wind cooling detection value and the liquid cooling detection value are numerically compared with the preset wind cooling detection threshold and the preset liquid cooling detection threshold, respectively. If the wind cooling detection value or the liquid cooling detection value does not exceed the corresponding preset threshold, it is determined that the diesel generator is in an abnormal heat dissipation cooling state;

[0021] The total time that the diesel generator is in an abnormal heat dissipation cooling state per unit time is obtained and marked as the cooling operation judgment value, and the cooling operation judgment value is numerically compared with the preset cooling operation judgment threshold. If the cooling operation judgment value exceeds the preset cooling operation judgment threshold, a cooling alarm signal is generated; if the cooling operation judgment value does not exceed the preset cooling operation judgment threshold, a cooling qualified signal is generated.

[0022] Furthermore, the specific analysis process of liquid cooling tracking analysis is as follows:

[0023] The delivery speed and temperature of the coolant during the liquid cooling process of the diesel generator are obtained, and the deviation value of the delivery speed compared to the set standard speed is marked as the cooling delivery speed value, and the deviation value of the temperature compared to the set standard temperature is marked as the cooling delivery temperature value; the liquid cooling detection value is obtained by weighted summing the cooling delivery speed value and the cooling delivery temperature value.

[0024] Furthermore, the specific analysis process of the wear impact assessment module is as follows:

[0025] The lubrication system in the diesel generator is monitored, a number of sampling time points are set in a unit time, the oil pressure in the lubrication system at the corresponding sampling time point is collected and the deviation value compared with the set standard oil pressure is marked as the oil pressure difference value, and the oil temperature in the lubrication system at the corresponding sampling time point is collected and the deviation value compared with the set standard oil temperature is marked as the oil temperature difference value;

[0026] The concentration of foreign particles in the lubricating oil at the corresponding sampling time point is collected and marked as the oil foreign particle value, and the oil sampling detection value is obtained by weighted summing the oil pressure difference value, the oil temperature difference value and the oil foreign particle value, and the oil sampling detection value at the corresponding detection time point is numerically compared with the preset oil sampling detection threshold value. If the oil sampling detection value exceeds the preset oil sampling detection threshold value, the corresponding detection time point is marked as an obstruction time point;

[0027] The number of obstruction time points within a unit time is obtained and the ratio is calculated with the total number of detection time points to obtain the wear impact abnormal value, and the oil sampling detection values ​​of all detection time points within a unit time are averaged to obtain the wear impact performance value, and the wear impact abnormal value and the wear impact performance value are numerically compared with the preset wear impact abnormal threshold and the preset wear impact performance threshold, respectively. If the wear impact abnormal value or the wear impact performance value exceeds the corresponding preset threshold, a wear risk signal is generated; if both the wear impact abnormal value and the wear impact performance value do not exceed the corresponding preset threshold, a wear controllable signal is generated.

[0028] Furthermore, the management terminal is communicatively connected to the generator evaluation module, and the operation control evaluation module is used to set a monitoring period, evaluate the operating performance of the diesel generator during the monitoring period, collect the total operating time of the diesel generator during the monitoring period and mark it as the generator operating time value, as well as collect the number and value of the generator parameter control alarm signal, emission flammability alarm signal, cooling alarm signal and wear risk signal generated by the diesel generator during the monitoring period and mark them as the generator abnormal frequency value, calculate the ratio of the generator abnormal frequency value to the generator operating time value to obtain the generator evaluation value, and compare the generator evaluation value with the preset generator evaluation threshold value. If the generator evaluation value exceeds the preset generator evaluation threshold, a generator abnormality signal is generated, and the generator abnormality signal is sent to the management terminal.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. In the present invention, the parameter control performance of the diesel generator during operation is analyzed through the parameter control analysis module, the exhaust gas of the diesel generator is monitored and the combustion performance is analyzed when the generator parameter control qualified signal is generated, the heat dissipation and cooling performance of the diesel generator is analyzed when the emission flammability qualified signal is generated, and the wear hidden dangers of the diesel generator are analyzed when the cooling qualified signal is generated, so as to realize comprehensive monitoring and control of the diesel generator, which is conducive to ensuring the safe, stable and energy-saving operation of the diesel generator and significantly reducing the difficulty of operation supervision of the diesel generator;

[0033] Figure 1 This is a system block diagram of Embodiment 1 of the present invention;

[0034] Figure 2 This is a system block diagram of Embodiment 2 of the present invention. DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1: Figure 1 As shown, the intelligent diesel generator operation control system based on high efficiency and energy saving proposed by the present invention includes a parameter control analysis module, an emission monitoring feedback module, a cooling operation judgment module, a wear impact assessment module and a management terminal;

[0037] The parameter control analysis module analyzes the parameter control performance during the operation of the diesel generator, and generates a generator parameter control qualified signal or a generator parameter control alarm signal based on it. When the generator parameter control alarm signal is generated, it is sent to the management terminal. When the management terminal receives the generator parameter control alarm signal, it issues an early warning to remind the management personnel to suspend the operation of the diesel generator as needed, and inspect and repair the diesel generator to ensure the operating stability of its various parameters, which is conducive to the safe and energy-saving operation of the diesel generator. The specific analysis process of the parameter control analysis module is as follows:

[0038] Monitor the mechanical parameters (such as the speed and torque of the diesel generator), electrical parameters (such as the output voltage, current, power, power factor, etc.) and fuel system parameters (such as the fuel consumption rate and fuel pressure of the diesel generator) of the diesel generator, collect the test data of various parameters, and compare the test data with the corresponding preset data requirements. If the test data does not meet the corresponding preset data requirements, it is judged that the corresponding parameters are in a poorly controlled state;

[0039] The total duration and the number of occurrences of the corresponding parameter in a poorly controlled state per unit time are marked as the total poorly controlled time value and the poorly controlled frequency value, respectively, and the total poorly controlled time value and the poorly controlled frequency value are weighted and summed to obtain the control characteristic value of the corresponding parameter; that is, the total poorly controlled time value and the poorly controlled frequency value are respectively assigned corresponding preset weight coefficients in advance, and the total poorly controlled time value and the poorly controlled frequency value are respectively multiplied by the corresponding preset weight coefficients, and the two sets of multiplication results are summed to obtain the control characteristic value of the corresponding parameter;

[0040] The control characteristic value is numerically compared with the corresponding preset control characteristic threshold. If the control characteristic value exceeds the corresponding preset control characteristic threshold, it indicates that the control performance of the corresponding parameter is poor, and the control judgment symbol ZY-1 is assigned to the corresponding parameter; if there is a parameter assigned with the control judgment symbol ZY-1 per unit time, it indicates that the operation control performance of the diesel generator is poor, and a generator parameter control alarm signal is generated.

[0041] Furthermore, if there is no parameter assigned with the control judgment symbol ZY-1 within a unit time, the ratio of the control characteristic value of the corresponding parameter to the corresponding preset control characteristic threshold is marked as the control risk value, and the control risk values ​​of all operating parameters that need to be monitored and controlled during the operation of the diesel generator are averaged to obtain a comprehensive evaluation value; wherein, the larger the value of the comprehensive evaluation value, the worse the operation control performance of the diesel generator within a unit time;

[0042] The comprehensive evaluation value is numerically compared with the preset comprehensive evaluation threshold. If the comprehensive evaluation value exceeds the preset comprehensive evaluation threshold, it indicates that the operation control performance of the diesel generator is generally poor, and a generator parameter control alarm signal is generated; if the comprehensive evaluation value does not exceed the preset comprehensive evaluation threshold, it indicates that the operation control performance of the diesel generator is generally good, and a generator parameter control qualified signal is generated.

[0043] The parameter control analysis module sends the generator parameter control qualified signal to the emission monitoring feedback module. The emission monitoring feedback module monitors the exhaust gas of the diesel generator. When receiving the generator parameter control qualified signal, it analyzes the emission status of the diesel generator, and generates an emission flammability alarm signal or an emission flammability qualified signal accordingly. When the emission flammability alarm signal is generated, it is sent to the management terminal. When receiving the emission flammability alarm signal, the management terminal issues an early warning to remind the management personnel to take corresponding control measures to enable the fuel to be fully burned, reduce the energy consumption of the diesel generator, and improve its energy-saving effect. The specific analysis process of the emission monitoring feedback module is as follows:

[0044] The types of combustibles that need to be monitored in the exhaust gas of the diesel generator (including carbon monoxide, hydrocarbons, etc.) are obtained, the concentrations of various types of combustibles in the exhaust gas are collected, and a set of preset calorific value coefficients corresponding to each type of combustible is set in advance, wherein the values ​​of the preset calorific value coefficients are all positive numbers;

[0045] The concentration of the corresponding type of combustible is multiplied by the corresponding preset calorific value coefficient to obtain the combustible characteristic value, and the combustible characteristic values ​​of all types of combustibles that need to be monitored are summed up to obtain the combustible assessment value; wherein, the larger the combustible assessment value, the less sufficient the fuel of the current diesel generator is, and the less conducive it is to ensure its energy-saving effect;

[0046] The duration of occurrence of the combustibility assessment value exceeding the preset combustibility assessment threshold value per unit time is obtained and marked as the exhaust gas combustibility time value, and the exhaust gas combustibility time value is numerically compared with the preset exhaust gas combustibility time threshold value. If the exhaust gas combustibility time value exceeds the preset exhaust gas combustibility time threshold value, indicating that the fuel combustion performance of the diesel generator per unit time is poor, an exhaust combustibility alarm signal is generated;

[0047] If the exhaust gas flammable condition value does not exceed the preset exhaust gas flammable condition threshold, a flammable set is established for all flammable evaluation values ​​within a unit time, and the maximum value and average value in the flammable set are marked as the flammable high amplitude value and the flammable performance value respectively;

[0048] The emission combustible monitoring value is obtained by weighted summing the exhaust gas combustible time value, the combustible high amplitude value and the combustible performance value; that is, the exhaust gas combustible time value, the combustible high amplitude value and the combustible performance value are respectively assigned corresponding preset weight coefficients in advance, the exhaust gas combustible time value, the combustible high amplitude value and the combustible performance value are respectively multiplied by the corresponding preset weight coefficients, and the three sets of product results are summed up to obtain the emission combustible monitoring value; wherein, the larger the value of the emission combustible monitoring value, the worse the fuel combustion performance of the diesel generator per unit time;

[0049] The emission flammability monitoring value is numerically compared with the preset emission flammability monitoring threshold. If the emission flammability monitoring value exceeds the preset emission flammability monitoring threshold, it indicates that the fuel combustion performance of the diesel generator per unit time is poor, and an emission flammability alarm signal is generated; if the emission flammability monitoring value does not exceed the preset emission flammability monitoring threshold, it indicates that the fuel combustion performance of the diesel generator per unit time is good, and an emission flammability qualified signal is generated.

[0050] The emission monitoring feedback module sends the emission flammability qualified signal to the cooling operation judgment module. When the cooling operation judgment module receives the emission flammability qualified signal, it will analyze the heat dissipation and cooling performance of the diesel generator, and generate a cooling alarm signal or a cooling qualified signal accordingly. When the cooling alarm signal is generated, it will be sent to the user terminal. When the management terminal receives the cooling alarm signal, it will issue an early warning to remind the management personnel to check the corresponding cooling components in time to ensure the heat dissipation and cooling performance of the diesel generator, which is conducive to the safe and stable operation of the diesel generator. The specific analysis process of the cooling operation judgment module is as follows:

[0051] The wind speed of the cooling fan in the diesel generator is collected and the difference with the set standard wind speed is calculated and the absolute value is taken to obtain the wind cooling detection value, and the liquid cooling detection value is obtained through liquid cooling tracking analysis, specifically: the delivery speed and temperature of the coolant in the liquid cooling process of the diesel generator are obtained, and the deviation value of the delivery speed compared to the set standard speed is marked as the cooling delivery speed value, and the deviation value of the temperature compared to the set standard temperature is marked as the cooling delivery temperature value;

[0052] The liquid cooling detection value is obtained by weighted summing the cooling speed value and the cooling temperature value; that is, the cooling speed value and the cooling temperature value are respectively assigned corresponding preset weight coefficients in advance, and the cooling speed value and the cooling temperature value are respectively multiplied by the corresponding preset weight coefficients, and the two sets of product results are summed to obtain the liquid cooling detection value; wherein, the larger the value of the liquid cooling detection value, the worse the liquid cooling effect for the diesel generator;

[0053] The air cooling detection value and the liquid cooling detection value are numerically compared with the preset air cooling detection threshold and the preset liquid cooling detection threshold, respectively. If the air cooling detection value or the liquid cooling detection value does not exceed the corresponding preset threshold, it indicates that the cooling effect on the diesel generator is poor, and it is determined that the diesel generator is in an abnormal heat dissipation cooling state;

[0054] The total duration that the diesel generator is in an abnormal heat dissipation and cooling state per unit time is obtained and marked as the cooling operation judgment value, and the cooling operation judgment value is numerically compared with the preset cooling operation judgment threshold. If the cooling operation judgment value exceeds the preset cooling operation judgment threshold, it indicates that the current heat dissipation and cooling performance of the diesel generator is poor, and a cooling alarm signal is generated; if the cooling operation judgment value does not exceed the preset cooling operation judgment threshold, it indicates that the current heat dissipation and cooling performance of the diesel generator is good, and a cooling qualified signal is generated.

[0055] The cooling operation judgment module sends the cooling qualified signal to the wear impact assessment module. When receiving the cooling qualified signal, the wear impact assessment module analyzes the wear risks of the diesel generator, generates a wear risk signal or a wear controllable signal through analysis, and sends it to the user terminal when the wear risk signal is generated. When receiving the wear risk signal, the management terminal issues an early warning to remind the management personnel to replace the engine oil and control the delivery, so as to ensure that the corresponding components in the diesel generator are effectively lubricated, which is conducive to avoiding the wear of the corresponding internal components, and further ensuring the safe and stable operation of the diesel generator; the specific analysis process of the wear impact assessment module is as follows:

[0056] The lubrication system in the diesel generator is monitored, a number of sampling time points are set in a unit time, the oil pressure in the lubrication system at the corresponding sampling time point is collected and the deviation value compared with the set standard oil pressure is marked as the oil pressure difference value, and the oil temperature in the lubrication system at the corresponding sampling time point is collected and the deviation value compared with the set standard oil temperature is marked as the oil temperature difference value;

[0057] The concentration of foreign particles in the lubricating oil at the corresponding sampling time point is collected and marked as the oil impurity value, and the oil sampling detection value is obtained by weighted summing the oil pressure difference value, the oil temperature difference value and the oil impurity value, that is, the oil pressure difference value, the oil temperature difference value and the oil impurity value are weighted and summed in advance to obtain the oil sampling detection value, and the corresponding preset weight coefficients are respectively assigned, and the oil pressure difference value, the oil temperature difference value and the oil impurity value are respectively multiplied by the corresponding preset weight coefficients, and the three sets of product results are summed to obtain the oil sampling detection value;

[0058] The larger the value of the oil sampling detection value is, the worse the oil condition is at the corresponding detection time point; the oil sampling detection value at the corresponding detection time point is compared with the preset oil sampling detection threshold value. If the oil sampling detection value exceeds the preset oil sampling detection threshold value, it indicates that the oil condition at the corresponding detection time point is poor, which is not conducive to the components in the diesel generator to be fully lubricated to avoid wear, and the corresponding detection time point is marked as an obstruction time point;

[0059] The number of obstruction time points within a unit time is obtained and the ratio thereof is calculated with the total number of detection time points to obtain a wear influence abnormal value, and the oil sampling detection values ​​of all detection time points within a unit time are averaged to obtain a wear influence performance value, and the wear influence abnormal value and the wear influence performance value are numerically compared with a preset wear influence abnormal threshold and a preset wear influence performance threshold, respectively;

[0060] If the wear impact abnormal value or the wear impact performance value exceeds the corresponding preset threshold, it indicates that the components in the diesel generator are susceptible to wear, which is not conducive to ensuring the safe, stable and energy-saving operation of the diesel generator, and a wear risk signal is generated; if the wear impact abnormal value and the wear impact performance value do not exceed the corresponding preset threshold, it indicates that the components in the diesel generator can be fully lubricated and are not susceptible to wear, which is conducive to ensuring the safe, stable and energy-saving operation of the diesel generator, and a wear controllable signal is generated.

[0061] Embodiment 2: Figure 2 As shown, the difference between this embodiment and the first embodiment is that the management terminal is communicatively connected to the generator evaluation module, the operation control evaluation module is used to set the monitoring period, evaluate the operation performance of the diesel generator during the monitoring period, collect the total operation time of the diesel generator during the monitoring period and mark it as the generator operation time value, and collect the number and value of the generator parameter control alarm signal, emission flammability alarm signal, cooling alarm signal and wear risk signal generated by the diesel generator during the monitoring period and mark them as the generator frequency difference value;

[0062] The generator evaluation value is calculated by ratioing the generator abnormal frequency value with the generator operation time value, and the generator evaluation value is numerically compared with the preset generator evaluation threshold. If the generator evaluation value exceeds the preset generator evaluation threshold, it indicates that the operating performance of the diesel generator during the monitoring period is poor, and it is necessary to strengthen the operation supervision and daily maintenance of the diesel generator. In this way, a generator abnormality signal is generated and sent to the management terminal. When the management terminal receives the generator abnormality signal, it issues an early warning to remind management personnel to strengthen the operation supervision and daily maintenance of the diesel generator, ensure the performance of the diesel generator, and reduce the difficulty of supervision of the diesel generator.

[0063] The working principle of the present invention: when in use, the parameter control performance of the diesel generator during operation is analyzed through the parameter control analysis module, the exhaust gas of the diesel generator is monitored and the combustion performance is analyzed through the emission monitoring feedback module when the generator parameter control qualified signal is generated, the heat dissipation and cooling performance of the diesel generator is analyzed through the cooling operation judgment module when the emission flammability qualified signal is generated, and the wear risk of the diesel generator is analyzed through the wear impact assessment module when the cooling qualified signal is generated. The management terminal issues an early warning when receiving the generator parameter control alarm signal, the emission flammability alarm signal, the cooling alarm signal or the wear risk signal, so as to remind the management personnel to take reasonable response measures in time, realize comprehensive monitoring and control of the diesel generator, ensure the safe, stable and energy-saving operation of the diesel generator, and significantly reduce the difficulty of operation supervision of the diesel generator.
