[0006] 2) Manual refueling cannot be quantitatively controlled and has large errors.

[0007] 3) Manual refueling may result in missing refueling points, causing risk of damage to equipment. Summary of the Invention

[0008] In view of the deficiencies of the prior art, the present invention provides an automatic oil filling system, which solves the problem that the refueling points cannot be quantitatively controlled and the refueling time cannot be reasonably controlled.

[0009] To achieve the above objectives, the present invention is implemented through the following technical solutions: an automatic oil filling system, comprising:

[0010] A sensor data acquisition unit, used for transmitting the oil quantity data of the oil filling point to the oil filling point analysis unit;

[0011] The oil filling point analysis unit is used to analyze the acquired oil quantity data, monitor the remaining oil quantity at the oil filling point, and analyze and judge according to the vibration condition of the oil filling point, thereby generating a monitoring analysis signal and an oil filling analysis signal, and transmitting the monitoring analysis signal to the oil filling cycle analysis unit and the oil filling analysis signal to the oil filling quantity analysis unit;

[0012] The oil filling cycle analysis unit is used to process the acquired monitoring and analysis signals, calculate the oil consumption corresponding to the oil filling point, and calculate the average oil consumption of the oil filling point in combination with historical data, and analyze and generate a cycle calculation signal. The oil filling cycle analysis of the oil filling point is performed based on the calculated oil consumption information, and the oil filling cycle information is generated. The oil filling cycle information is transmitted to the oil filling management output unit and the oil filling amount analysis unit;

[0013] An oil filling amount analysis unit is used to process the obtained oil filling analysis signal and obtain the oil filling cycle information. The unit calculates the oil filling amount corresponding to the oil filling point based on the oil filling cycle information to generate oil filling information. The unit monitors the oil filling process based on the oil filling information and generates corresponding management information. The management information is then transmitted to the oil filling management output unit.

[0014] The oil filling management output unit is used to display the acquired management information and oil filling cycle information to the corresponding operator.

[0015] As a further solution of the present invention, the specific manner in which the oil filling point analysis unit generates the monitoring analysis signal and the oil filling analysis signal is as follows:

[0016] All oil filling points are numbered and recorded as i, where i = 1, 2, ..., j. At the same time, the remaining oil volume corresponding to the oil filling point i is obtained and recorded as Si. Then, the vibration frequency of the oil filling point corresponding to the remaining oil volume Si is obtained and recorded as Pi. The vibration frequency Pi is compared with the normal value Pz;

[0017] When the vibration frequency Pi is greater than the normal value Pz, it means that there is an abnormality in the corresponding vibration frequency Pi when the remaining oil amount Si, and an oil injection analysis signal is generated. Conversely, when the vibration frequency Pi is less than the normal value Pz, it means that there is no abnormality in the corresponding vibration frequency Pi when the remaining oil amount Si, and a monitoring and analysis signal is generated.

[0018] As a further solution of the present invention: the specific method of the oil filling cycle analysis unit generating the cycle calculation signal is:

At the same time, obtain the consumption and usage time corresponding to the analysis oil filling point, and calculate it according to the formula The fuel consumption corresponding to the analyzed refueling point is calculated and recorded as K1, and θ is the influencing factor. Then, with time t as the period, multiple monitoring points within the time period t are obtained and recorded as n, where n = 1, 2, ..., m. The fuel consumption corresponding to monitoring point n is calculated and recorded as Kn. At the same time, the average fuel consumption is calculated and recorded as Kp. Then, the average fuel consumption Kp is compared with K1.

[0020] When the average fuel consumption Kp is the same as the fuel consumption K1, the prediction time calculation is performed based on the fuel consumption K1, and a cycle calculation signal is generated. Conversely, when the average fuel consumption Kp is different from the fuel consumption K1, historical data is obtained, and the average fuel consumption of the refueling point is calculated based on the historical data. At the same time, the prediction time calculation is performed based on the average fuel consumption, a cycle calculation signal is generated, and the cycle calculation signal is analyzed.

[0021] As a further solution of the present invention, the specific method in which the oil filling cycle analysis unit analyzes the cycle calculation signal is as follows:

[0022] Obtain the oil injection amount corresponding to the oil injection point and calculate the corresponding oil injection cycle according to the oil consumption standard. The specific formula is: Wherein a2 is a preset proportional coefficient, and the oil filling cycle information is generated at the same time, and then the oil filling cycle information is transmitted to the oil filling management output unit.

[0023] As a further solution of the present invention, the specific method of generating the oil filling information by the oil filling amount analysis unit is as follows:

[0024] Obtain the oiling point and the historical data corresponding to the oiling point. Then, obtain the oiling amount corresponding to the oiling point based on the historical data and generate the oiling amount interval. At the same time, obtain the oiling consumption corresponding to the oiling point and calculate the oiling amount corresponding to the oiling point according to the formula: Oiling amount = Oiling amount × Oiling cycle × a3, where a3 is a preset proportional coefficient, the specific value of which is set by the operator. Match the calculated oiling amount with the oiling amount interval;

[0025] When the oil injection amount is within the oil injection amount interval, the oil injection analysis is performed based on the calculated oil injection amount, and the oil injection information is generated. Conversely, when the oil injection amount is not within the oil injection amount interval, the oil injection amount changes in the historical data are judged to generate the oil injection information.

[0026] As a further solution of the present invention, the specific method for the oil filling amount analysis unit to judge the oil filling amount change in the historical data and generate the oil filling information is as follows:

[0027] The number of oiling times corresponding to the oiling point in the historical data is obtained and recorded as c, and c=1, 2, ..., o, and o represents the number of oiling times. At the same time, the oiling amount corresponding to the oiling point is obtained and recorded as Lc. The corresponding main relationship diagram is established with the number of oiling times on the horizontal axis and the oiling amount on the vertical axis. The change of the oiling amount is judged according to the relationship diagram. When the oiling amount decreases, an oiling amount decrease signal is generated. Conversely, when the oiling amount increases, an oiling amount increase signal is generated.

[0028] As a further solution of the present invention, the specific method in which the oil injection amount analysis unit analyzes the oil injection amount reduction signal is as follows:

[0029] Determine the relationship between the oil injection amount and the oil injection amount range. If the oil injection amount is less than the minimum value of the oil injection amount range, oil injection is performed based on the current oil injection amount and oil injection information is generated. If the oil injection amount is greater than the maximum value of the oil injection amount range, oil injection is performed based on the maximum value of the oil injection amount range and oil injection information is generated.

[0030] As a further solution of the present invention, the specific method in which the oil injection amount analysis unit analyzes the oil injection amount increase signal is as follows:

[0031] Determine the relationship between the oil injection amount and the oil injection amount interval. If the oil injection amount is less than the minimum value of the oil injection amount interval, obtain the minimum value of the oil injection amount interval as the standard to generate the oil injection amount information. Conversely, if the oil injection amount is greater than the maximum value of the oil injection amount interval, generate the oil injection amount information based on the oil injection amount.

[0032] As a further solution of the present invention, the specific manner in which the oil filling amount analysis unit monitors the oil filling process and generates corresponding management information based on the oil filling information is as follows:

[0033] The real-time data of the sensor is obtained, and the real-time data is the real-time oil injection amount, and the real-time data is compared with the warning value, and the warning value is represented as the maximum oil injection amount. When the real-time data is greater than the warning value, a stop signal is generated. Conversely, when the real-time data is less than the warning value, a filling signal is generated. The stop signal, filling signal and oil injection information are integrated to obtain management information, and the management information is transmitted to the oil injection management output unit.

[0034] The present invention provides an automatic oil filling system. Compared with the prior art, it has the following advantages:

[0035] The present invention collects the oiling parameters corresponding to different oiling points, analyzes them according to the oiling point parameters, and conducts a comprehensive analysis from two aspects of oiling amount and oiling cycle. On the one hand, it realizes quantitative oiling of the oiling points, and on the other hand, it can realize periodic oiling.

BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Figure 1 This is a schematic diagram of the system of the present invention. DETAILED DESCRIPTION

[0037] 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.

[0038] For example 1, please refer to Figure 1 The present application provides an automatic oil filling system, including a sensor data acquisition unit, an oil filling point analysis unit, an oil filling cycle analysis unit, an oil filling amount analysis unit and an oil filling management output unit.

[0039] The sensor data acquisition unit is used to acquire the oil quantity data of different oil filling points and transmit the oil quantity data to the oil filling point analysis unit.

[0040] The oil filling point analysis unit is used to analyze the acquired oil quantity data, monitor the remaining oil quantity at the oil filling point, and analyze and judge the vibration of the oil filling point to generate a monitoring analysis signal and an oil filling analysis signal. The specific generation method is as follows:

[0041] All oil filling points are numbered and recorded as i, where i = 1, 2, ..., j, where j represents the number of oil filling points. At the same time, the remaining oil volume corresponding to the oil filling point i is obtained and recorded as Si. Then, the vibration frequency of the oil filling point corresponding to the remaining oil volume Si is obtained and recorded as Pi. The vibration frequency is obtained by a vibration sensor and compared with the normal value Pz. The normal value represents the vibration frequency corresponding to the normal operation of the equipment. The specific value of the normal value is set by the operator based on experience.

[0042] When the vibration frequency Pi is greater than the normal value Pz, it means that there is an abnormality in the corresponding vibration frequency Pi when the remaining oil amount Si, and an oil injection analysis signal is generated. Conversely, when the vibration frequency Pi is less than the normal value Pz, it means that there is no abnormality in the corresponding vibration frequency Pi when the remaining oil amount Si, and a monitoring and analysis signal is generated. At the same time, the monitoring and analysis signal is transmitted to the oil injection cycle analysis unit, and the oil injection analysis signal is transmitted to the oil injection amount analysis unit.

[0043] Suppose a conveyor has two oil filling points, labeled 1 and 2. The sensor measures that when the remaining oil volume S1 at oil filling point 1 is 0.5 liters, its vibration frequency P1 is 45Hz. Based on past experience, the normal vibration frequency Pz of this type of compressor is set to 40Hz. Since P1 exceeds Pz, the system determines that there is an abnormality at oil filling point 1 and generates an oil filling analysis signal, prompting the operator to check for possible faults or wear. On the contrary, if the vibration frequency P2 of oil filling point 2 is 38Hz when the remaining oil volume S2 is 0.3 liters, which is lower than the set normal value of 40Hz, the system determines that the oil filling point is normal and generates a monitoring and analysis signal.

[0044] The oil filling cycle analysis unit is used to process the acquired monitoring and analysis signals, calculate the oil consumption corresponding to the oil filling point, and calculate the average oil consumption of the oil filling point in combination with historical data, and analyze and generate a cycle calculation signal. The oil consumption information obtained by the comprehensive calculation is used to perform oil filling cycle analysis on the oil filling point and generate oil filling cycle information. The specific method of generating the oil filling cycle information is as follows:

[0045] Obtain the oil filling point corresponding to the monitoring analysis signal and record it as the analysis oil filling point. At the same time, obtain the consumption and usage time corresponding to the analysis oil filling point, and calculate it according to the formula The fuel consumption corresponding to the analyzed refueling point is calculated and recorded as K1, and θ is the influencing factor. Then, with time t as the period, which can be daily, weekly, or monthly, multiple monitoring points within the time period t are obtained, recorded as n, where n = 1, 2, ..., m, and the fuel consumption corresponding to monitoring point n is calculated and recorded as Kn. Each monitoring point represents the fuel consumption measurement value at a different time point in the period. At the same time, the average fuel consumption is calculated and recorded as Kp. Then, the average fuel consumption Kp is compared with K1;

[0046] Assume the maintenance team monitors fuel consumption weekly (period t). They set three monitoring points: Monday, Wednesday, and Friday. Over the course of a week, the fuel consumption values ​​are K1 = 2 liters, K2 = 1.8 liters, and K3 = 2.1 liters. The calculated average fuel consumption, Kp, is (2 + 1.8 + 2.1) / 3 = 1.93 liters.

[0047] When the fuel consumption mean Kp is the same as the fuel consumption K1, the prediction time calculation is performed based on the fuel consumption K1 and a cycle calculation signal is generated. Conversely, when the fuel consumption mean Kp is different from the fuel consumption K1, historical data is obtained and the average fuel consumption of the refueling point is calculated based on the historical data. At the same time, the prediction time calculation is performed based on the average fuel consumption and a cycle calculation signal is generated.

[0048] The specific method for calculating average fuel consumption is to obtain the historical records corresponding to the oiling points in the analysis data, as well as the corresponding oiling intervals in the history. Then, the corresponding fuel consumption is calculated based on the oiling intervals. The obtained fuel consumption values ​​are averaged to obtain the average fuel consumption. Assuming that the conveyor's oiling records for the past six months show that the oiling interval is approximately 30 days and the oil injection volume is 2 liters each time, by analyzing this data, we can calculate the average monthly fuel consumption of the pump to be approximately 6 liters (2 liters every 30 days x 2).

[0049] Then, the generated cycle calculation signal is analyzed to obtain the oil injection amount corresponding to the oil injection point. The oil injection amount here is the average of all oil injection amounts in the historical data. The corresponding oil injection cycle is calculated according to the oil consumption standard, and the oil injection cycle information is generated at the same time. Then, the oil injection cycle information is transmitted to the oil injection management output unit. Specifically, the calculation method here is Wherein a2 is the preset proportional coefficient, and the specific value is set by the operator. Meanwhile, the fuel consumption standard here is expressed as fuel consumption K1 or average fuel consumption.

[0050] Similarly, all oil filling points are analyzed to obtain the corresponding oil filling cycles.

[0051] The oil filling management output unit is used to transmit the acquired oil filling cycle information to the corresponding operator.

[0052] Embodiment 2, as the embodiment 2 of the present invention, is implemented on the basis of embodiment 1, and differs from embodiment 1 in that.

[0053] The oil filling amount analysis unit is used to process the obtained oil filling analysis signal and obtain the oil filling cycle information. The unit calculates the oil filling amount corresponding to the oil filling point based on the oil filling cycle information to generate oil filling information. The unit monitors the oil filling process based on the oil filling information and generates corresponding management information. The specific method of generating the management information is as follows:

[0054] Obtain a refueling point and obtain historical data corresponding to the refueling point. Then, obtain the refueling amount corresponding to the refueling point based on the historical data and generate a refueling amount interval. The refueling amount interval here is represented by the minimum refueling amount and the maximum refueling amount existing in the historical data. At the same time, obtain the fuel consumption corresponding to the refueling point. The fuel consumption here is the numerical standard in Example 1, specifically the fuel consumption K1 or the average fuel consumption. The refueling amount corresponding to the refueling point is calculated according to the formula: Refueling amount = fuel consumption × refueling cycle × a3. Where a3 is a preset proportional coefficient, the specific value of which is set by the operator. Match the calculated refueling amount with the refueling amount interval.

[0055] When the oil injection amount is within the oil injection amount interval, the oil injection analysis is performed based on the calculated oil injection amount, and the oil injection information is generated. Conversely, when the oil injection amount is not within the oil injection amount interval, the oil injection amount change in the historical data is judged to generate the oil injection information. The specific judgment method is:

[0056] Obtain the oiling times of the corresponding oiling point in the historical data, denoted as c, where c=1, 2, ..., o, and o represents the oiling times. At the same time, obtain the oiling amount corresponding to the oiling point, denoted as Lc. Establish a corresponding main relationship diagram with the oiling times as the horizontal axis and the oiling amount as the vertical axis. Determine the change in the oiling amount based on the relationship diagram. If the oiling amount decreases, a signal indicating an oiling amount decreases is generated. Conversely, if the oiling amount increases, a signal indicating an oiling amount increase is generated.

[0057] When the oil injection amount increase signal is generated, the relationship between the oil injection amount and the oil injection amount interval is judged. If the oil injection amount is less than the minimum value of the oil injection amount interval, the minimum value of the oil injection amount interval is obtained as the standard to generate the oil injection amount information. Conversely, if the oil injection amount is greater than the maximum value of the oil injection amount interval, the oil injection amount information is generated based on the oil injection amount. For example, the oil injection amount is 3, and the oil injection amount interval is [5,9]. In this case, the oil injection amount is less than the minimum value of the oil injection amount interval, that is, 5. Therefore, the oil injection amount of 5 is selected as the standard for oil injection to generate the oil injection information. If the oil injection amount is 10, the oil injection amount is greater than the maximum value of the oil injection amount interval, that is, 9. In this case, 10 is used as the standard for oil injection and oil injection information is generated.

[0058] When the oil filling amount decrease signal is generated, the relationship between the oil filling amount and the oil filling amount interval is determined. If the oil filling amount is less than the minimum value of the oil filling amount interval, oil filling is performed based on the current oil filling amount and oil filling information is generated. If the oil filling amount is greater than the maximum value of the oil filling amount interval, oil filling is performed based on the maximum value of the oil filling amount interval and oil filling information is generated.

[0059] Then, the oil filling process is monitored according to the generated oil filling information, and the real-time data of the sensor is obtained. The real-time data obtained here is the real-time oil filling amount, and the real-time data is compared with the warning value. The warning value here is expressed as the maximum oil filling amount. When the real-time data is greater than the warning value, a stop signal is generated. Conversely, when the real-time data is less than the warning value, a filling signal is generated. The stop signal, filling signal and oil filling information are integrated to obtain management information, and the management information is transmitted to the oil filling management output unit.

[0060] The oil filling management output unit is used to display the acquired management information to the corresponding operator.

[0061] Embodiment 3, as the third embodiment of the present invention, focuses on combining the implementation processes of embodiment 1 and embodiment 2.

[0062] Some of the data in the above formulas are dimensionless and numerically calculated. Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0063] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
