Description

Technical Field

[0001] The present invention relates to the technical field of blood centrifuge management, and particularly to a host computer management system for a medical blood centrifuge. Background Art

[0002] In the medical field, especially in clinical tests, blood product production, scientific research and other fields, as a key device, the operating state of a medical blood centrifuge directly affects the quality and safety of experimental results. Therefore, an efficient and reliable system is needed to manage and monitor the operation of the centrifuge to ensure that the device is always in the best working state. With the continuous development of medical technology and the increasing diversification of user needs, traditional centrifuge management systems have limitations in function expansion and customization. The automated functions of the host computer management system can meet the growing needs and personalized requirements of users, and improve the flexibility and applicability of the device.

[0003] When the traditional management system is applied, it is difficult to evaluate the operating parameters of the centrifuge in real time and accurately, which will lead to the inability to detect equipment abnormalities in time, affecting the accuracy of experimental results. And due to the different severity levels of the abnormal state of the centrifuge, there are also no effective measures to warn the abnormal state of the centrifuge. To a certain extent, it will cause operation delays. In severe cases, it is easy to cause the equipment to stop unexpectedly or even be damaged, affecting the experimental progress and results. Therefore, how to analyze the operating state of the centrifuge and give graded warnings according to the abnormal state of the centrifuge to weaken the serious consequences caused by the abnormal state is the problem we need to solve. For this reason, a host computer management system for a medical blood centrifuge is proposed. Summary of the Invention

[0020] The centrifugation program module is used to select a preset centrifugation program and monitor the operating status of the centrifuge in real time, including speed, acceleration, temperature, current, voltage, and centrifugal force parameters. Among them, speed, acceleration, temperature, current, and voltage are measured by corresponding sensors and returned to be displayed on the interface; the centrifugal force parameter is calculated through the rotor radius and rotational speed, and the data is saved or displayed on the interface. Its expression is: gForce(RCF) = RPM 3 × 1.118 × 10 -5 × r, where gForce(RCF) represents the relative centrifugal force generated by the centrifuge at a given rotational speed and rotor radius, RPM represents the rotational speed, which is the number of revolutions per minute of the centrifuge, 1.118 is a conversion factor used to convert the square of RPM in the calculation of RCF, 10 -5 is a scaling factor for calculation, r is the rotor radius, representing the radius of the centrifuge rotor. The relative centrifugal force gForce(RCF) increases with the increase of the rotational speed and is proportional to the square of the rotational speed;

[0025] A further improvement of the technical solution of the present invention lies in that: in the centrifugation control operation module, the process of receiving a user instruction and sending it to the lower computer of the centrifuge for execution is as follows:

[0026] The user inputs a start or stop instruction through the touch screen or physical buttons;

[0027] The system analyzes the received instruction, confirms the specific content and target operation of the instruction, and converts the user instruction into a control signal or instruction format recognizable by the lower computer of the centrifuge;

[0028] Through serial communication, the control signal is sent to the lower computer of the centrifuge. After receiving the control signal, the lower computer of the centrifuge analyzes and confirms the corresponding start or stop operation and its parameters;

[0029] The lower computer of the centrifuge converts the parsed instruction into a corresponding hardware control signal to drive the centrifuge to perform the corresponding operation. If the instruction is to start, the lower computer of the centrifuge starts the motor and runs at the set speed and time. If the instruction is to stop, the lower computer of the centrifuge stops the motor and terminates the centrifugation process;

[0030] The lower computer of the centrifuge feeds back the execution result to the system to confirm whether the operation is successful. The system updates the user interface according to the feedback information and displays the current device status.

[0031] A further improvement of the technical solution of the present invention lies in that: in the data processing and analysis module, the process of monitoring the operating state of the centrifuge and detecting abnormal situations is as follows:

[0032] Through various sensors connected to the centrifuge, the operating parameters of the centrifuge are collected, including speed, temperature, acceleration, current, and voltage parameters. Among them, the sensors include a speed sensor, a temperature sensor, an acceleration sensor, a current sensor, and a voltage sensor;

[0033] The collected data is stored in the system database, including historical data and real-time data, for subsequent analysis and review;

[0034] The collected data is preprocessed, including cleaning and formatting, to ensure the accuracy and consistency of the data, eliminate possible noise and outliers, and analyze the preprocessed data to extract the key performance parameters of the centrifuge;

[0035] The operating state of the centrifuge is continuously monitored, and the safety thresholds for normal operation are preset to ensure that the centrifuge operates under safe and stable conditions;

[0036] Analyze each abnormal situation in the historical data of the centrifuge and issue three-level alarms of prompt, warning, and shutdown according to the severity. Among them, corresponding alarms are issued for different levels of abnormalities. A prompt alarm is issued for minor abnormal situations such as door cover protection and operation errors. A warning alarm is issued for moderately severe abnormal situations such as imbalance, overspeed, temperature alarm, rotor error, motor not rotating, communication failure, Hall alarm, frequency converter communication failure, and frequency converter failure. A shutdown alarm is issued for severe abnormal situations such as module protection, overcurrent, overvoltage, and undervoltage;

[0037] Compare the real-time data with the preset safe operation threshold, analyze the change trend of each operating parameter of the centrifuge, detect whether there is a situation beyond the normal range, and conduct in-depth analysis of the detected abnormalities to determine the cause and location of the failure.

[0038] A further improvement of the technical solution of the present invention lies in that in the fault diagnosis module, the prediction process of the future state and potential faults of the equipment is as follows:

[0039] Extract the historical data of the centrifuge operation parameters from the system database, including the operation status, maintenance records, and fault history of the equipment, and extract the relevant data of the current detection results;

[0040] Extract key features from the historical data and detection results, and use the historical data combined with machine learning algorithms to train a fault prediction model to identify patterns and features related to faults. Among them, the key features include rotational speed, acceleration, temperature, current, and voltage, and set the standard values of each key feature;

[0041] Extract the associated feature data of the rotational speed and acceleration of the equipment based on the historical data, analyze to obtain the overspeed evaluation index, evaluate the impact of the overspeed risk of the equipment, extract the temperature-associated feature data of the equipment based on the historical data, analyze to obtain the over-temperature evaluation index, evaluate the impact of the over-temperature risk of the equipment, extract the associated feature data of the current and voltage of the equipment based on the historical data, analyze to obtain the voltage evaluation index, and evaluate the risk impact caused by the current and voltage problems of the equipment;

[0042] Compare the current real-time data with the reference data in the fault prediction model, comprehensively analyze the overspeed evaluation index, over-temperature evaluation index, and voltage evaluation index, calculate the fault warning index, and evaluate the potential fault risk of the equipment;

[0043] Based on the fault warning index and the fault prediction model, predict the future state of the centrifuge, including the possible fault type, time, and severity of the fault;

[0044] According to the predicted fault severity and the impact degree on the equipment operation, divide different warning levels, namely the minor warning level, medium warning level, and severe warning level, and match the corresponding warning thresholds for each warning level.

[0045] A further improvement of the technical solution of the present invention lies in that the expression of the overspeed evaluation index is:

[0046]

[0047] Wherein, SI is the overspeed evaluation index, RM i is the rotational speed measured at the i-th time, RM std is the standard value of the rotational speed, Ac i is the acceleration measured at the i-th time, Ac std is the standard value of the acceleration, n is the number of speed measurements. It should be noted that the larger the value of SI, the higher the overspeed risk;

[0048] The expression of the over-temperature evaluation index is as follows:

[0049]

[0050] where TI is the over-temperature evaluation index, and T j is the temperature value of each measurement, and max(T j ) is the maximum value of the measured temperature values, and T std is the standard value of the temperature. It should be noted that the larger the value of TI, the higher the over-temperature risk;

[0051] The expression of the voltage evaluation index is as follows:

[0052]

[0053] where VI is the voltage evaluation index, and V k is the voltage measured at the k-th time, and V std is the standard value of the voltage, and I l is the current measured at the l-th time, and I std is the standard value of the current, and m is the number of measurements of the voltage and current. It should be noted that the larger the value of VI, the higher the risk of voltage and current problems.

[0054] A further improvement of the technical solution of the present invention lies in that: the expression of the fault warning index is as follows:

[0055] FAN = w 1 ×SI + w 2 ×TI + w 3 ×VI;

[0056] where FAN is the fault warning index, SI is the overspeed evaluation index, and w 1 is the weight of the overspeed evaluation index, TI is the over-temperature evaluation index, and w 2 is the weight of the over-temperature evaluation index, VI is the voltage evaluation index, and w 3 is the weight of the voltage evaluation index. It should be noted that FAN > 0;

[0057] Multiple said warning levels correspond to multiple said warning thresholds, where the warning thresholds include an upper threshold and a lower threshold;

[0058] Multiple said warning levels and multiple said warning thresholds satisfy the following relationship:

[0059] Minor warning level 0 < FAN ≤ FAN M ; The equipment is in good operating condition, there is no immediate fault risk, there may be minor abnormalities, but it does not affect normal operation temporarily and can be arranged for handling during daily maintenance;

[0060] Medium warning level FANM <FAN ≤ FAN D ; The device performance may be affected to a certain extent, and inspections and maintenance need to be arranged as soon as possible;

[0061] Severe warning level: FAN > FAN D ; There is a serious risk of equipment failure, and the equipment should be immediately shut down for a comprehensive inspection and repair;

[0062] Among them, FAN is the fault warning index, FAN M is the lower threshold corresponding to the medium warning level and the upper threshold corresponding to the minor warning level, and FAN D is the lower threshold corresponding to the severe warning level and the upper threshold corresponding to the medium warning level.

[0063] A further improvement of the technical solution of the present invention lies in that: in the fault prompt module, the process of issuing a warning notification includes:

[0064] Receiving the diagnostic result of the equipment status from the fault diagnosis module, evaluating the severity of the fault according to the fault diagnosis result, and determining the warning level to be issued;

[0065] Generating a corresponding warning notification according to the evaluation result, including the fault type, possible impacts, and recommended action plans;

[0066] Directly displaying the warning information on the display screen of the system, accompanied by visual prompts such as flashing and color change, emitting a sound alarm, distinguishing different warning levels by long beeping and short beeping, and sending an email or text message notification to the designated maintenance personnel or management personnel to ensure that the equipment status can be timely known even if not on site;

[0067] Recording all warning events in the system, including time, fault type, notification method, and recipient, and receiving feedback to track the progress of fault handling to optimize the maintenance plan.

[0068] Due to the adoption of the above technical solution, the technical progress achieved by the present invention compared with the prior art is:

[0089] The centrifugal control operation module is used to provide buttons or instructions, receive user instructions, and send them to the lower computer of the centrifuge for execution to start and stop the operation of the centrifuge. The user inputs start or stop instructions through the touch screen or physical buttons.

[0091] Based on the historical data and detection results, the fault diagnosis module predicts the future state and potential faults of the equipment, and divides the early warning levels in combination with the fault severity;

[0092] The fault prompt module is used to issue early warning notifications of corresponding statuses for the fault diagnosis results, reduce the impact brought by equipment failures, reduce maintenance costs, and improve equipment utilization rate.

[0093] Example 2, as Figure 3 shown, on the basis of Example 1, the present invention provides a technical solution: Preferably, in the fault diagnosis module, the prediction process of the future state and potential faults of the equipment is as follows:

[0094] Extract the historical data of the centrifuge operating parameters from the system database, including the operating status, maintenance records, and fault history of the equipment, and extract the relevant data of the current detection results. Extract the key features from the historical data and detection results, and use the historical data combined with machine learning algorithms to train a fault prediction model to identify the patterns and features related to faults. Among them, the key features include rotational speed, acceleration, temperature, current, and voltage, and set the standard values of each key feature. Extract the correlation feature data of the rotational speed and acceleration of the equipment based on the historical data, analyze to obtain the overspeed evaluation index, and evaluate the impact of the overspeed risk of the equipment. Extract the temperature correlation feature data of the equipment based on the historical data, analyze to obtain the over-temperature evaluation index, and evaluate the impact of the over-temperature risk of the equipment. Extract the correlation feature data of the current and voltage of the equipment based on the historical data, analyze to obtain the voltage evaluation index, and evaluate the risk impact caused by the current and voltage problems of the equipment. Compare the current real-time data with the reference data in the fault prediction model, comprehensively analyze the overspeed evaluation index, over-temperature evaluation index, and voltage evaluation index, calculate the fault warning index, and evaluate the potential fault risk of the equipment. Based on the fault warning index and the fault prediction model, predict the future state of the centrifuge, including the possible fault type, time, and severity of the fault. According to the predicted fault severity and the impact on the equipment operation, divide different warning levels, namely the minor warning level, medium warning level, and severe warning level, and match the corresponding warning thresholds for each warning level;

[0095] Furthermore, the expression of the overspeed evaluation index is:

[0096]

[0097] Where SI is the overspeed evaluation index, RM i is the rotational speed of the i-th measurement, RM std is the standard value of the rotational speed, Ac i is the acceleration of the i-th measurement, Ac std is the standard value of the acceleration, n is the number of speed measurements. It should be noted that the larger the value of SI, the higher the overspeed risk;

[0098] The expression of the over-temperature evaluation index is:

[0099]

[0100] Where TI is the over-temperature evaluation index, T j is the temperature value of each measurement, max(T j ) is the maximum value of the measured temperature values, T std is the standard value of the temperature. It should be noted that the larger the value of TI, the higher the over-temperature risk;

[0101] The expression of the voltage evaluation index is:

[0102]

[0103] Among them, VI is the voltage evaluation index, V k is the voltage measured at the k-th measurement, V std is the standard value of the voltage, I l is the current measured at the l-th measurement, I std is the standard value of the current, m is the number of measurements of voltage and current. It should be noted that the larger the value of VI, the higher the risk of voltage and current problems;

[0104] Furthermore, the expression of the fault warning index is:

[0105] FAN = w 1 ×SI + w 2 ×TI + w 3 ×VI;

[0106] Among them, FAN is the fault warning index, SI is the overspeed evaluation index, w 1 is the weight of the overspeed evaluation index, TI is the over-temperature evaluation index, w 2 is the weight of the over-temperature evaluation index, VI is the voltage evaluation index, w 3 is the weight of the voltage evaluation index. It should be noted that FAN > 0, all evaluation indexes and FAN are non-negative values. As the problems of overspeed, over-temperature, current and voltage increase, the corresponding evaluation indexes will increase. FAN reflects the overall fault risk of the equipment, and the higher its value, the greater the equipment fault risk;

[0107] Multiple warning levels correspond to multiple warning thresholds. Among them, the warning thresholds include upper limit thresholds and lower limit thresholds;

[0108] Multiple warning levels and multiple warning thresholds satisfy the following relationship:

[0109] Minor warning level 0 < FAN ≤ FAN M ; The equipment is in good operating condition, there is no immediate fault risk, there may be minor abnormalities, but it does not affect normal operation for the time being, and it can be arranged for handling during daily maintenance;

[0110] Medium warning level FAN M < FAN ≤ FAN D ; The performance of the equipment may be affected to a certain extent, and it is necessary to arrange inspections and maintenance as soon as possible;

[0111] Severe warning level FAN > FAN D ; The equipment has a serious fault risk and should be shut down immediately for a comprehensive inspection and repair;

[0112] Among them, FAN is the fault warning index, FANM is the lower threshold value corresponding to the medium warning level and the upper threshold value corresponding to the minor warning level, FAN D is the lower threshold value corresponding to the severe warning level and the upper threshold value corresponding to the medium warning level;

[0113] In the fault prompt module, the process of sending a warning notice includes:
