Description

Technical Field

[0001] The present invention relates to the technical field of diesel generator control and management, and in particular to an intelligent diesel generator operation control system based on high efficiency and energy saving. Background Art

[0002] A diesel generator is a device that converts the chemical energy of diesel into electrical energy. 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 equipment, diesel generators play an irreplaceable role in power supply.

[0003] A Chinese invention patent with publication number CN114810401A discloses a diesel generator control system and a diesel generator. This invention's technical solution controls the fuel injection rate of the diesel engine's oil pump to achieve speed regulation. By adjusting the speed, the operating temperature of the diesel engine is regulated, preventing the diesel engine's temperature from being too high, which would reduce the diesel generator's service life.

[0004] However, in actual application, the above-mentioned technical solution is difficult to conduct a progressive and reasonable analysis of the diesel generator's parameter control performance, combustible emission conditions, cooling performance, and wear impact, and to provide timely warnings. It is also 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 existing technology 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 a generator parameter control alarm signal, and sends the generator parameter control qualified signal to the emission monitoring feedback module when it generates a generator parameter control qualified signal.

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

[0010] 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, and when the cooling qualified signal is generated, it will be sent to the wear impact assessment module; when the wear impact assessment module receives the cooling qualified signal, it will analyze the wear risks of the diesel generator, and 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 it receives 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: the mechanical parameters, electrical parameters and fuel system parameters of the diesel generator are monitored, the detection data of each parameter is collected, and the detection data is compared with the corresponding preset data requirements. If the detection data does not meet the corresponding preset data requirements, it is determined that the corresponding parameter is in a poor control state;

[0012] 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.

[0013] Furthermore, if there is no parameter assigned 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.

[0014] Furthermore, the specific analysis process of the emission monitoring feedback module is as follows: 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, a set of preset calorific value coefficients corresponding to each type of combustible is set in advance, 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 and calculated to obtain the combustibility assessment value;

[0015] Obtain the duration of time in which the flammability assessment value exceeds the preset flammability assessment threshold within a unit time and mark it as the exhaust gas flammability time value, compare the exhaust gas flammability time value with the preset exhaust gas flammability time threshold, and generate an exhaust flammability alarm signal if the exhaust gas flammability time value exceeds the preset exhaust gas flammability time threshold;

[0016] 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 summation of 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 flammable alarm signal is generated; if the emission flammable monitoring value does not exceed the preset emission flammable monitoring threshold, an emission flammable qualified signal is generated.

[0017] Furthermore, the specific analysis process of the cooling operation judgment module is as follows:

[0018] 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 an air cooling detection value, and the liquid cooling detection value is obtained through liquid cooling tracking analysis. 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 exceeds the corresponding preset threshold, it is determined that the diesel generator is in an abnormal heat dissipation cooling state;

[0019] The total length of 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.

[0020] Furthermore, the specific analysis process of liquid cooling tracking analysis is as follows:

[0021] 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.

[0022] Furthermore, the specific analysis process of the wear impact assessment module is as follows:

[0023] The lubrication system of the diesel generator is monitored, and a number of sampling time points are set within 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;

[0024] The concentration of foreign particles in the lubricating oil at the corresponding sampling time point is collected and marked as an oil foreign particle value. An oil sampling detection value is calculated by weighted summing the oil pressure difference value, the oil temperature difference value, and the oil foreign particle value. The oil sampling detection value at the corresponding detection time point is numerically compared with a 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.

[0025] The number of obstruction time points in unit time is obtained and the ratio is calculated with the total number of detection time points to obtain the wear impact abnormality value, and the oil sampling detection values ​​of all detection time points in unit time are averaged to obtain the wear impact performance value, and the wear impact abnormality value and the wear impact performance value are numerically compared with the preset wear impact abnormality threshold and the preset wear impact performance threshold respectively. If the wear impact abnormality value or the wear impact performance value exceeds the corresponding preset threshold, a wear risk signal is generated; if neither the wear impact abnormality value nor the wear impact performance value exceeds the corresponding preset threshold, a wear controllable signal is generated.

[0026] 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, 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 deviation value, calculate the ratio of the generator frequency deviation 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.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. In the present invention, the parameter control performance of the diesel generator during operation is analyzed through the parameter control analysis module. When the generator parameter control qualified signal is generated, the exhaust gas of the diesel generator is monitored and the combustion performance is analyzed. When the emission flammability qualified signal is generated, the heat dissipation and cooling performance of the diesel generator is analyzed. When the cooling qualified signal is generated, the wear hidden dangers of the diesel generator are analyzed. This realizes 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 reduces the difficulty of diesel generator operation supervision.

[0029] 2. In the present invention, the operating performance of the diesel generator during the monitoring period is evaluated through the operation control evaluation module, and it is determined whether a generator abnormality signal is generated. When the generator abnormality signal is generated, the management personnel are reminded to strengthen the operation supervision and daily maintenance of the diesel generator, ensure the performance of the diesel generator, and further reduce the difficulty of supervising the diesel generator.

[0031] Figure 1 This is a system block diagram of Embodiment 1 of the present invention;

[0032] Figure 2 This is a system block diagram of Example 2 of the present invention. DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0034] Example 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 and analysis module, an emission monitoring feedback module, a cooling operation judgment module, a wear impact assessment module and a management terminal;

[0035] 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 the analysis. 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 to inspect and repair the diesel generator to ensure the operational 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:

[0036] 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 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;

[0037] The total duration and 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, corresponding preset weight coefficients are assigned to the total poorly controlled time value and the poorly controlled frequency value in advance, and the total poorly controlled time value and the poorly controlled frequency value are multiplied by the corresponding preset weight coefficients, and the two sets of product results are summed to obtain the control characteristic value of the corresponding parameter;

[0038] 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 within a unit time, it indicates that the operation control performance of the diesel generator is poor, and a generator parameter control alarm signal is generated.

[0039] Furthermore, if there is no parameter assigned 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;

[0040] 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.

[0041] 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 the management terminal receives the emission flammability alarm signal, it issues an early warning to remind the management personnel to take corresponding control measures to ensure that the fuel is 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:

[0042] Obtain the types of combustibles that need to be monitored in the exhaust gas of the diesel generator (including carbon monoxide, hydrocarbons, etc.), collect the concentrations of various types of combustibles in the exhaust gas, and set a set of preset calorific value coefficients corresponding to each combustible in advance, where the values ​​of the preset calorific value coefficients are all positive numbers;

[0043] The concentration of the corresponding type of combustible material is multiplied by the corresponding preset calorific value coefficient to obtain the combustibility characteristic value, and the combustibility characteristic values ​​of all types of combustible materials to be monitored are summed up to obtain the combustibility assessment value. Among them, the larger the combustibility assessment value, the less sufficient the fuel of the current diesel generator is, and the less conducive it is to ensuring its energy-saving effect;

[0044] The duration of time during which the combustibility assessment value exceeds 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;

[0045] If the exhaust gas flammability time condition value does not exceed the preset exhaust gas flammability time condition threshold, all flammability evaluation values ​​within the unit time are used to establish a flammability set, and the maximum value and average value in the flammability set are marked as the flammability high amplitude value and flammability performance value respectively;

[0046] The emission flammability monitoring value is calculated by weighted summing the exhaust gas flammability time value, the flammability high amplitude value and the flammability performance value; that is, the exhaust gas flammability time value, the flammability high amplitude value and the flammability performance value are respectively assigned corresponding preset weight coefficients in advance, and the exhaust gas flammability time value, the flammability high amplitude value and the flammability performance value are respectively multiplied by the corresponding preset weight coefficients, and the three sets of product results are summed to obtain the emission flammability monitoring value; wherein, the larger the value of the emission flammability monitoring value, the worse the fuel combustion performance of the diesel generator per unit time;

[0047] 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.

[0048] The emission monitoring feedback module sends the emission combustibility qualified signal to the cooling operation judgment module. When the cooling operation judgment module receives the emission combustibility qualified signal, it analyzes the heat dissipation and cooling performance of the diesel generator and generates a cooling alarm signal or a cooling qualified signal accordingly. When the cooling alarm signal is generated, it is sent to the user terminal. When the management terminal receives the cooling alarm signal, it issues 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:

[0049] The wind speed of the cooling fan in the diesel generator is collected and the difference between it and the set standard wind speed is calculated and the absolute value is taken to obtain the air 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 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;

[0050] The liquid cooling detection value is calculated by performing a weighted summation of the cooling speed value and the cooling temperature value. Specifically, 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. The two sets of product results are summed to obtain the liquid cooling detection value. The larger the value of the liquid cooling detection value, the worse the liquid cooling effect of the diesel generator.

[0051] 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 exceeds the corresponding preset threshold, it indicates that the cooling effect of the diesel generator is poor, and it is determined that the diesel generator is in an abnormal heat dissipation cooling state;

[0052] The total length of time 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.

[0053] The cooling operation judgment module sends the cooling qualified signal to the wear impact assessment module. Upon receiving the cooling qualified signal, the wear impact assessment module analyzes the wear risks of the diesel generator and generates a wear risk signal or a wear controllable signal through analysis. When the wear risk signal is generated, it is sent to the user terminal. Upon receiving the wear risk signal, the management terminal issues an early warning to remind the management personnel to replace the engine oil and adjust the oil supply to ensure that the corresponding components in the diesel generator are effectively lubricated, which is conducive to avoiding 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:

[0054] The lubrication system of the diesel generator is monitored, and a number of sampling time points are set within 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;

[0055] The concentration of foreign particles in the lubricating oil at the corresponding sampling point is collected and marked as an engine oil particle value, and an engine oil sampling detection value is obtained by performing a weighted sum calculation on the engine oil pressure difference value, the engine oil temperature difference value, and the engine oil particle value. That is, the engine oil sampling detection value obtained by performing a weighted sum calculation on the engine oil pressure difference value, the engine oil temperature difference value, and the engine oil particle value is assigned a corresponding preset weight coefficient in advance, and the engine oil pressure difference value, the engine oil temperature difference value, and the engine oil particle value are multiplied by the corresponding preset weight coefficient respectively, and the three sets of product results are summed to obtain the engine oil sampling detection value;

[0056] The larger the oil sampling detection value, the worse the oil condition 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. If the oil sampling detection value exceeds the preset oil sampling detection threshold, it indicates that the oil condition at the corresponding detection time point is poor, which is not conducive to sufficient lubrication of the components in the diesel generator to avoid wear, and the corresponding detection time point is marked as an obstruction time point.

[0057] Obtaining the number of obstruction time points within a unit time and calculating the ratio thereof to the total number of detection time points to obtain a wear impact abnormality value, and calculating the average of the oil sampling detection values ​​of all detection time points within the unit time to obtain a wear impact performance value, and numerically comparing the wear impact abnormality value and the wear impact performance value with a preset wear impact abnormality threshold and a preset wear impact performance threshold, respectively;

[0058] 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.

[0059] Example 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, 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, 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 abnormal frequency value;

[0060] The generator evaluation value is calculated by ratioing the generator frequency deviation 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 the operation supervision and daily maintenance of the diesel generator need to be strengthened. Then, 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.

[0061] The working principle of the present invention is as follows: when in use, the parameter control performance of the diesel generator during operation is analyzed through the parameter control analysis module; when the generator parameter control qualification signal is generated, the exhaust gas of the diesel generator is monitored and the combustion performance is analyzed through the emission monitoring feedback module; when the emission flammability qualification signal is generated, the heat dissipation and cooling performance of the diesel generator is analyzed through the cooling operation judgment module; when the cooling qualification signal is generated, the wear risk of the diesel generator is analyzed through the wear impact assessment module; 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.

The intelligent diesel generator operation control system based on high efficiency and energy saving according to claim 1 is characterized in that: The specific analysis process of the wear impact assessment module is as follows: The lubrication system of the diesel generator is monitored, and a number of sampling time points are set within 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; The concentration of foreign particles in the lubricating oil at the corresponding sampling time point is collected and marked as an oil foreign particle value. An oil sampling detection value is calculated by weighted summing the oil pressure difference value, the oil temperature difference value, and the oil foreign particle value. The oil sampling detection value at the corresponding detection time point is numerically compared with a 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. The number of obstruction time points in unit time is obtained and the ratio is calculated with the total number of detection time points to obtain the wear impact abnormality value, and the oil sampling detection values ​​of all detection time points in unit time are averaged to obtain the wear impact performance value, and the wear impact abnormality value and the wear impact performance value are numerically compared with the preset wear impact abnormality threshold and the preset wear impact performance threshold respectively. If the wear impact abnormality value or the wear impact performance value exceeds the corresponding preset threshold, a wear risk signal is generated; if neither the wear impact abnormality value nor the wear impact performance value exceeds the corresponding preset threshold, a wear controllable signal is generated.

The intelligent diesel generator operation control system based on high efficiency and energy saving according to claim 1 is characterized in that: The management terminal is communicatively connected to the generator evaluation module. 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, 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 deviation value. The generator frequency deviation value is calculated by ratio with the generator operating time value to obtain the generator evaluation 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, a generator abnormality signal is generated, and the generator abnormality signal is sent to the management terminal.
