This control method helps to reduce the impact and wear of the locomotive when passing through curves and switches, and improves the running stability and safety. Therefore, the research on the monorail crane based on the combined control of an internal combustion engine and an air compressor is of great significance.

[0003] Existing monorail crane operation equipment usually adopts a separate power supply mechanism, such as an internal combustion engine function or an air compressor power supply. The single nature of the power source limits the flexibility and adaptability of the equipment, making the performance of the equipment limited under different working conditions and environments. The single power supply method may also cause the equipment to be unable to operate normally during faults or maintenance, affecting production efficiency and the continuity of transportation operations.

This analysis method cannot comprehensively evaluate and optimize the dynamic performance of the system, which may lead to problems such as slow system response, unstable operation, poor coordination, and inaccurate braking, thereby affecting work efficiency, safety, and reliability.

[0020] Please refer to Figure 1 As shown, the present invention provides a monorail crane operation system based on the combined control of an internal combustion engine and an air compressor. The system includes a monorail crane operation mechanism setting module, an operation instruction acquisition module, an internal combustion engine self-check module, an air compressor self-check module, a start permission judgment module, a start sensitivity analysis module, an operation coordination analysis module, a braking accuracy analysis module, and an abnormal direction identification module.

[0021] The monorail crane operation mechanism setting module is used to set the monorail crane operation mechanism. The monorail crane operation mechanism is composed of an internal combustion engine, an air compressor, a monorail, a lifting component, a braking component, and a driving component.

[0022] It should be noted that the power of the monorail crane operation mechanism in the present invention is provided jointly by the internal combustion engine and the air compressor. Specifically, the power sources of the braking component and the driving component are provided jointly by the internal combustion engine and the air compressor.

[0023] The operation instruction acquisition module is used to acquire operation instructions, and the operation instructions include a start instruction and a braking instruction.

[0024] It should be noted that when the mechanism receives a start command, the monorail crane running mechanism needs to perform a start operation, and when the mechanism receives a braking command, the monorail crane running mechanism needs to perform a braking operation.

[0025] The internal combustion engine self-check module is used to perform a self-check on the internal combustion engine when a start command is received, obtain internal combustion engine self-check data, and analyze the quality evaluation of the internal combustion engine.

[0026] It should be noted that the reason for performing a self-check on the internal combustion engine: The self-check of the internal combustion engine is a key link to ensure the safe and stable operation of the equipment. By detecting various performance indicators of the internal combustion engine, potential faults can be discovered and processed in a timely manner to ensure the safety of operators, improve equipment efficiency, reduce energy consumption, and meet legal requirements.

[0027] In a preferred embodiment of the present invention, the internal combustion engine self-check data includes engine speed, fuel pressure, intake air flow rate, and coolant temperature.

[0028] It should be noted that the reasons for selecting engine speed, fuel pressure, intake air flow rate, and coolant temperature as the internal combustion engine self-check data are as follows: 1. Engine speed is an important indicator of the operating state of the internal combustion engine. The instantaneous speed contains rich information about the working state of the internal combustion engine and is often used to diagnose uneven rotation of the internal combustion engine, fuel system faults, valve faults, and piston faults, etc. 2. Fuel pressure is a key parameter for evaluating the performance of the fuel system. By detecting the fuel pressure, the working states of components such as the fuel pump, fuel filter, and fuel pressure regulator can be judged. 3. Air flow rate is the main source of oxygen required during the combustion process of the internal combustion engine. By monitoring the intake air flow rate, the performance of components such as the air filter, intake pipeline, and turbocharger (if applicable) can be evaluated. 4. Coolant temperature reflects the performance of the internal combustion engine cooling system. By monitoring the coolant temperature, faults in the cooling system, such as radiator blockage, water pump failure, or coolant leakage, can be discovered in a timely manner.

[0029] It should be noted that the engine speed can be collected using a speed sensor, the fuel pressure can be collected using a pressure sensor, the intake air flow rate can be collected using a gas flow sensor, and the coolant temperature can be collected using a temperature sensor.

[0030] In a preferred embodiment of the present invention, to analyze the quality evaluation of the internal combustion engine, an internal combustion engine quality evaluation index needs to be constructed, and the specific method is as follows: Extract the engine speed, fuel pressure, intake air flow rate, and coolant temperature corresponding to the self-check of the internal combustion engine, and record them as , , , .

[0031] Using the formula Obtain the quality evaluation index of the internal combustion engine through analysis , where represents the preset reference engine speed, represents the preset reference fuel pressure, represents the preset reference intake air flow rate, represents the preset reference coolant temperature, represents the allowable difference between the preset engine speed and the reference engine speed, represents the allowable difference between the preset fuel pressure and the reference fuel pressure, represents the allowable difference between the preset intake air flow rate and the reference intake air flow rate, represents the allowable difference between the preset coolant temperature and the reference coolant temperature.

[0032] It should be noted that the settings of the reference engine speed, reference fuel pressure, reference intake air flow rate, and reference coolant temperature are based on the following: 1. The designed speed of the internal combustion engine is one of its basic parameters, and its maximum speed and normal operating speed range are usually determined during the design stage. The setting of the reference engine speed should be based on the designed speed of the internal combustion engine to ensure its operation within a safe and stable speed range. 2. The fuel supply system of the internal combustion engine includes components such as fuel pumps, fuel filters, and fuel pressure regulators. The setting of the reference fuel pressure should be based on the performance parameters of these components and the overall design requirements of the fuel supply system. 3. The combustion process of the internal combustion engine requires sufficient air supply. The setting of the reference intake air flow rate should be based on the combustion requirements of the internal combustion engine to ensure sufficient air supply under different operating conditions. 4. The cooling system of the internal combustion engine includes components such as radiators, water pumps, and coolant circulation pipelines. The setting of the reference coolant temperature should be based on the performance parameters of these components and the overall design requirements of the cooling system.

[0033] The air compressor self-check module is used to perform a self-check on the air compressor when receiving a start command, obtain air compressor self-check data, and analyze the quality evaluation of the air compressor.

[0034] It should be noted that the reason for performing a self-check on the air compressor: As a commonly used device in industrial production, the operating state of the air compressor is directly related to the safety and stability of the production line. Through self-check, potential faults in the device, such as damaged filters, electrical faults, and blocked oil circuits, can be detected in a timely manner, thus avoiding greater safety problems caused by these faults.

[0035] In a preferred embodiment of the present invention, the air compressor self-check data includes output gas flow rate, output pressure, vibration frequency, and exhaust temperature.

[0036] It should be noted that the reasons for selecting the output gas flow, output pressure, vibration frequency, and exhaust temperature as the self-check data of the air compressor are as follows: 1. The output gas flow is one of the important indicators to measure the working ability of the air compressor. By monitoring the output gas flow, the production capacity of the air compressor can be intuitively understood, so as to evaluate whether its performance meets the standards. 2. The stability of the output pressure is directly related to the stability of the air compressor system. By monitoring the output pressure, it can be judged whether the air compressor can continuously provide a stable gas pressure output, thus ensuring the stable operation of the production line. 3. The vibration frequency is an important indicator reflecting the mechanical health status of the air compressor. By monitoring the vibration frequency, problems such as wear, looseness, or imbalance of mechanical components can be detected in a timely manner, thus preventing the occurrence of equipment failures. 4. The exhaust temperature is an important indicator to measure the heat load of the air compressor. By monitoring the exhaust temperature, it can be judged whether the air compressor is overheated, and corresponding heat dissipation measures can be taken to prevent the equipment from being damaged due to overheating.

[0037] It should be noted that the output gas flow can be collected by using a gas flow sensor, the output pressure can be collected by using a pressure sensor, the vibration frequency can be collected by using a frequency collection device, and the exhaust temperature can be collected by using a temperature sensor.

[0038] In a preferred embodiment of the present invention, to analyze the quality evaluation situation of the air compressor, an air compressor quality evaluation index needs to be constructed, and the specific method is as follows: Extract the output gas flow, output pressure, vibration frequency, and exhaust temperature corresponding to the quality inspection of the air compressor, and record them as , , , .

[0039] Using the formula Analyze to obtain the air compressor quality evaluation index , where represents the preset reference output gas flow, represents the preset reference output pressure, represents the preset reference vibration frequency, represents the preset reference exhaust temperature, represents the allowable difference between the preset output gas flow and the reference output gas flow, represents the allowable difference between the preset output pressure and the reference output pressure, represents the allowable difference between the preset vibration frequency and the reference vibration frequency, represents the allowable difference between the preset exhaust temperature and the reference exhaust temperature.

[0040] It should be noted that the settings of the reference output gas flow, reference output pressure, reference vibration frequency, and reference exhaust temperature are based on the following: 1. The design specifications of the air compressor usually specify its maximum output gas flow. The reference output gas flow should be set based on this design specification to ensure that the device does not exceed its design capacity during actual operation, thus avoiding overload and damage. 2. The design pressure of the air compressor is the maximum working pressure it can withstand. The reference output pressure should be set based on this design pressure to ensure that the device does not exceed its design pressure range during actual operation. 3. The vibration frequency is an important indicator reflecting the mechanical health status of the air compressor. The reference vibration frequency should be set based on the normal vibration range of the device to monitor whether there is abnormal vibration in the device. 4. The exhaust temperature is an important indicator measuring the heat load of the air compressor. The reference exhaust temperature should be set based on the heat load management ability of the device to monitor whether the device is overheated.

[0041] The start permission judgment module is used to judge whether to allow the start operation based on the internal combustion engine quality evaluation situation and the air compressor quality evaluation situation.

[0042] In a preferred embodiment of the present invention, the specific method for judging whether to allow the start operation is as follows: Extract the internal combustion engine quality evaluation index and the air compressor quality evaluation index, and then compare them with the pre-set internal combustion engine quality evaluation index threshold and the air compressor quality evaluation index threshold respectively. If the internal combustion engine quality evaluation index is greater than or equal to the internal combustion engine quality evaluation index threshold and the air compressor quality evaluation index is greater than or equal to the air compressor quality evaluation index threshold, it is judged that the start operation is allowed; otherwise, it is judged that the start operation is not allowed.

[0045] Taking time as the abscissa and output power as the ordinate, plot the output power change curve, analyze the output power change curve, record the time when the output power first reaches the pre-set output power recognition threshold as the output power compliance monitoring time, and calculate the difference between the output power compliance monitoring time and the start command receiving time to obtain the output power successful response duration.

[0046] Exemplarily, the output power recognition threshold is .

[0047] Calculate the deviation of the output power successful response duration by calculating the difference between the output power successful response duration and a pre-set reference response duration, and then calculate the output power successful response deviation degree by calculating the ratio to the reference response duration.

The type of the driving road condition specifically includes a horizontal road condition, an uphill road condition, and a downhill road condition, and then divide the monitoring sections according to the type of the driving road condition to obtain several monitoring sections.

[0053] Mark the intersection of adjacent monitoring sections as a monitoring point, and obtain the moving speed of the monorail crane running mechanism corresponding to each monitoring point.

[0054] Calculate the average moving speed by calculating the average value of the moving speeds of each monitoring point, and then calculate the deviation of the moving speed of each monitoring point by calculating the difference between the moving speed of each monitoring point and the average moving speed. Then, calculate the moving speed fluctuation degree of each monitoring point by calculating the ratio of the absolute value of the moving speed deviation of each monitoring point to the average moving speed.

[0055] Calculate the average value of the moving speed fluctuation degrees of each monitoring point, and then take the reciprocal of the sum with the correction adjustment coefficient to obtain the running coordination index of the monorail crane running mechanism.

[0056] It should be noted that in practice, when the monorail crane running mechanism is at the changing position of each new driving road condition, the established dynamic balance is easily damaged due to the change of the driving road condition, and then the moving speed changes. Therefore, analyzing the moving speed of adjacent monitoring sections can reflect the running coordination of the monorail crane running mechanism.

[0057] The braking accuracy analysis module is used to perform a braking operation when a braking instruction is received, and to obtain in real time the braking time, braking distance, and load of the monorail crane running mechanism, and analyze the braking accuracy of the monorail crane running mechanism.

[0059] It should be noted that when the monorail crane running mechanism is under a relatively low load, it is easier to decelerate.

[0060] Obtain the type of the traveling road condition corresponding to the current braking, and then obtain the braking road condition correction index of the monorail crane running mechanism , when the type of the traveling road condition is a horizontal road condition, an uphill road condition, and a downhill road condition, the corresponding braking road condition correction indexes are respectively .

[0061] It should be noted that when the monorail crane running mechanism is in an uphill road condition, it is easier to decelerate.

[0063] Use the formula to analyze and obtain the braking accuracy index of the monorail crane running mechanism , where represents a preset reference braking time, and represents a preset reference braking distance.

[0064] The abnormal direction identification module is used to judge whether there is an operation abnormality in the monorail crane running mechanism based on the starting sensitivity, operation coordination, and braking accuracy of the monorail crane running mechanism. If so, further identify the specific abnormal direction.

[0065] In a preferred embodiment of the present invention, the specific method for judging whether there is an operation abnormality in the monorail crane running mechanism is as follows: Extract the starting sensitivity index, operation coordination index, and braking accuracy index corresponding to the monorail crane running mechanism, and then perform a weighted summation calculation to obtain the quality evaluation index of the monorail crane running mechanism.

[0066] Exemplarily, the weights corresponding to the starting sensitivity index, operation coordination index, and braking accuracy index are .

[0067] Compare the quality evaluation index of the monorail crane running mechanism with the pre-set quality evaluation index threshold. If the quality evaluation index of the monorail crane running mechanism is greater than or equal to the quality evaluation index threshold, it is determined that there is no abnormal operation. Otherwise, it is determined that there is abnormal operation.

[0068] In a preferred embodiment of the present invention, the method for identifying the specific abnormal direction is as follows: Extract the starting sensitivity index, running coordination index, and braking accuracy index corresponding to the monorail crane running mechanism, and then compare them with the pre-set starting sensitivity index threshold, running coordination index threshold, and braking accuracy index threshold respectively.

[0069] If the starting sensitivity index corresponding to the monorail crane running mechanism is less than the starting sensitivity index threshold, it is determined that the specific abnormal direction is starting sensitivity abnormality.

[0070] If the running coordination index corresponding to the monorail crane running mechanism is less than the running coordination index threshold, it is determined that the specific abnormal direction is running coordination abnormality.

[0071] If the braking accuracy index corresponding to the monorail crane running mechanism is less than the braking accuracy index threshold, it is determined that the specific abnormal direction is braking accuracy abnormality.

[0072] It should be noted that the specific abnormal direction can be one or more of starting sensitivity abnormality, running coordination abnormality, and braking accuracy abnormality.
