[0023] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0024] A manned centrifuge is a device that is driven by a main motor to drive the main bearing and drive the main arm to rotate, and cooperates with other axial movements such as a gimbal (roll frame and cockpit) to achieve multi-degree-of-freedom overload simulation. It can conduct ground high-load aviation medical training for pilots. Due to factors such as the huge system of the centrifuge, complex and diverse signals, and multi-axial composite overload, the safety requirements for the equipment and the subjects are relatively high. The safety monitoring subsystem monitors various signals of the system in real time and takes multiple protection measures to avoid damage to the equipment or the subjects caused by faults.

[0025] The embodiments of the present invention disclose a centrifuge safety monitoring system, as Figure 1 shown, the system includes:

[0026] The main arm slave station 101 is used to collect the first operation parameters and the first operation state of the main arm of the centrifuge, and integrate them into main arm data.

[0027] Exemplarily, the main arm slave station 101 is installed near the rotation axis of the main arm of the centrifuge and can be composed of a programmable controller and sensors for relevant data acquisition. The first operation parameters can be the operation parameters in the main arm slave station 101, such as the main rotational acceleration, the main rotational speed, the operation parameters of the roll and pitch axis motors, the main brake operation parameters, the shaft brake operation parameters, and the system balance parameters, etc. The first operation state is the data used to characterize the operation state of the centrifuge, such as the pitch axis motor state (operating state, angular position, temperature, etc.), the main brake and shaft brake states, and the system balance state, etc. The embodiments of the present invention do not limit the composition of the main arm slave station 101, the data types and the number of the first operation parameters, and those skilled in the art can determine according to actual needs.

[0028] The cockpit slave station 102 is used to collect the second operation parameters, the second operation state of the cockpit of the centrifuge, and the monitoring signals of the subject, and integrate them into cockpit data.

[0029] Exemplarily, the cockpit slave station 102 is installed in the cockpit part of the centrifuge and can be composed of a programmable controller and relevant sensors. The second operation parameters can be the balance parameters of the cockpit in the cockpit slave station 102, the triaxial acceleration, the air supply pressure, the cockpit door lock data, and the video data for monitoring the subject (which can include the face monitoring audio and video and the overall monitoring audio and video), and the monitoring of the physiological signals of the subject. The second operation state is to judge whether the corresponding data is normal according to the data of the second operation parameters. The embodiments of the present invention do not limit the composition of the cockpit slave station 102, the data types and the number of the second operation parameters, and those skilled in the art can determine according to actual needs.

[0030] The electrical slave station 103 is used to collect the electrical operation parameters of the centrifuge and integrate them into electrical data.

[0031] Exemplarily, the electrical slave station 103 can be installed in the basement of the centrifuge and can be composed of a programmable controller and relevant sensors. The electrical operating parameters can include the distribution system status (main transformer switchgear, excitation switchgear, etc.), the fan cooling system (operating status, temperature, etc.), the compressed air system (operating status of the air compression system installed in the basement, outlet pressure), the UPS system (power status, battery voltage, internal temperature, etc.), the frequency converter system (operating status of the frequency converter installed in the basement, water temperature, etc.), the main motor (operating status of the main motor installed in the basement, stator temperature, bearing temperature, etc.), and the main brake hydraulic station (operating status, hydraulic oil pressure, hydraulic oil quantity status, etc.). The collected electrical operating parameters are integrated and collectively referred to as electrical data.

[0032] The safety master station 104 is used to obtain the main arm data, cockpit data, and electrical data, and analyze them based on the main arm data, cockpit data, and electrical data to obtain an analysis result.

[0033] Exemplarily, the safety master station 104 is installed in the control room and can be composed of a programmable controller and relevant data sensors. The data transmission between the safety master station 104 and each slave station can be transmitted by a signal slip ring. After all slave station data uses high-speed Ethernet as the communication medium, the signal is transmitted to the safety master station 104 through the signal slip ring for logical judgment and comprehensive processing. For the specific judgment and processing process, the corresponding processing measures can be obtained by querying the table shown in Table 1. For example, in Table 1, when the value monitored by the smoke detection signal during the operation of the centrifuge is greater than the preset threshold, a shutdown operation is executed, and a normal shutdown or an emergency shutdown operation can be executed according to the magnitude of the detected value. Before the monitored signal value returns to the normal range, operation is not allowed; when the fan cooling system has abnormal operation data before or during operation, an alarm signal is issued. Other processing measures can be deduced by analogy according to the content in Table 1.

[0034] Specifically, during the operation of the centrifuge, the safety master station obtains the data of each slave station in real time. Among them, the multi-axial acceleration and main rotation acceleration signals remain stable during normal operation, and only when they are over-limited does the safety master station 104 need to make a comprehensive judgment. Therefore, a separate path can be led out before the signal enters the safety master station 104 to the electronic limiter for judgment. When the over-limit value is reached, the electronic limiter transmits the data to the safety master station 104, which can reduce the operating load of the safety master station 104. On the one hand, the safety master station 104 transmits the processed signal to the safety monitoring host computer for real-time display, and on the other hand, it is directly connected to the drive system of the centrifuge to send control signals such as emergency shutdown. In addition to obtaining the integrated data of each slave station, the safety master station 104 can also obtain the video of the main engine room of the safety master station 104, door locks, smoke detection signals, and the status of the drive system of the centrifuge through signal cables.

[0037]

[0038] Note: Without distinction between before and during operation, the processing results are the same.

[0039] After obtaining the corresponding analysis results based on the signals of each slave station acquired by the safety master station 104, corresponding processing measures are taken according to the analysis results. The corresponding processing measures, in addition to some basic processing measures in Table 1 above (due to the complexity of the centrifuge system, not all processing measures are listed), can also obtain the corresponding fault categories based on signal analysis, and classify the hazards caused to people or equipment according to the fault categories. When a fault in Table 1 occurs, the system jumps to the corresponding protection program for protection. The hierarchical protection measures can include centrifuge body protection measures, power-off self-protection measures, safety interlock protection measures, video monitoring and smoke detection protection of the operating environment, subject protection measures, load overlimit protection measures, and operator protection measures.

[0040] Among them, the centrifuge body protection measures mainly include: a. Adding overcurrent protection devices to components or systems with power supply to prevent damage to the equipment caused by short circuits or overloads; b. Making full use of the protection systems and devices of components with independent functions (such as UPS power supply, main motor, air compressor station, frequency converter, etc.), starting their own protection when the safety value exceeds the factory limit, and at the same time transmitting the signal to the corresponding slave station for comprehensive logical judgment; c. Arranging sensors at the main monitoring points, sending the signals to the safety master station 104 through the nearest slave station, and then the safety master station 104 makes logical judgments. If the limit is exceeded, relevant processes are started, that is, emergency shutdown or alarm.

[0041] The power-off self-protection measure mainly refers to connecting a UPS power supply to the low-voltage power supply input end of the centrifuge to prevent accidental injuries, data loss, and personal safety caused by power outages. It can provide power supply requirements of no less than 15 minutes for the main brake hydraulic controller, computer system, visual system, cockpit lighting, and medical monitoring equipment, etc. Each slave station can perform emergency operations when powered by the UPS, including starting the emergency shutdown process by the main brake hydraulic control system, evacuating the subjects, saving the test data, and shutting down each subsystem, etc.

[0042] The safety interlock protection measure mainly refers to that since the centrifuge is a high-speed rotating device, in order to prevent injuries caused by personnel entering and leaving during operation, non-contact magnetic safety switch monitoring sensors are installed on all doors leading to the main engine room for full monitoring. If the door is not closed before operation, the centrifuge is not allowed to run. If the door lock is opened during operation, the emergency shutdown process is started.

[0043] The protection for the operating environment through video monitoring and smoke detection mainly includes: installing monitoring cameras to comprehensively and without dead angles monitor the environment of the main engine room. Smoke detectors are installed in the main engine room, control room, motor room, high-voltage room, low-voltage distribution room, etc. to detect possible smoke and fire in the main engine room, control room, motor room, high-voltage room, and low-voltage distribution room.

[0044] The protection measures for the subjects mainly refer to the real-time monitoring of the physiological signals such as electrocardiogram, ear pulse, and respiration, as well as the audio and video signals such as voice and facial expressions of the subjects through the subject module in the cockpit slave station 102 to avoid the harm caused by the subjects fainting due to high loads.

[0045] The protection measures for load overlimit mainly refer to that in the high-overload test of the centrifuge, preventing load overlimit is an important measure to ensure the safety of the subjects. The centrifuge safety monitoring system is achieved through two layers of protection. The first layer is software protection. Load envelope lines and load growth rate envelope lines are additionally set for each overload curve. When the centrifuge is running, the triaxial acceleration sensors at the eye level position of the cockpit are collected in real time. When the actual overload exceeds the set value of the envelope line, it is automatically limited to the limit value, and this envelope line value can be modified by the operator according to the endurance level of the subjects and the training curve. The second layer of protection is hardware protection. An electronic limiter is used. The warning values and limit values of the loads in each direction (generally the limit load values that the human body can withstand after wearing anti-G equipment) and the rotation speed of the centrifuge platform (the acceleration sensors are installed at the end of the main arm, on the same horizontal plane as the triaxial acceleration sensors in the cockpit, and at the same distance from the main rotation center) are written into the limiter through the serial port. The sensor values are connected to the input end of the electronic limiter. When the load exceeds the warning value, a prompt is given, and when it exceeds the limit value, an emergency shutdown procedure is started. Multiple protections effectively avoid injuries caused by load overlimit.

[0046] The protection measures for the operators mainly include: adopting methods such as grounding and setting leakage switches to reduce the risk of electric shock to the operators.

[0047] The centrifuge safety monitoring system provided by the present invention includes a safety master station 104, a main arm slave station 101, a cockpit slave station 102, and an electrical slave station 103. Among them, the main arm slave station 101 is used to collect the first operating parameters and the first operating state of the main arm of the centrifuge and integrate them into main arm data; the cockpit slave station 102 is used to collect the second operating parameters, the second operating state of the cockpit of the centrifuge, and the monitoring signals of the subject and integrate them into cockpit data; the electrical slave station 103 is used to collect the electrical operating parameters of the centrifuge and integrate them into electrical data; the safety master station 104 is used to obtain the main arm data, the cockpit data, and the electrical data, and perform analysis based on the main arm data, the cockpit data, and the electrical data to obtain an analysis result. The centrifuge safety monitoring system adopts a master-slave structure. Each slave station analyzes and processes the nearest monitoring signals and then transmits them to the master station for integration. The master-slave stations have a high degree of modularization and strong scalability, solving the problems of long signal transmission distance and difficult signal integration.

[0049] Exemplarily, the main arm slave station 101 collects the balance state data of the main arm slave station 101 through the first balance module, where the balance state data can be whether the balance parameters during system operation exceed the preset threshold; the running state data of the axle motor is collected through the axle brake module, and the running state data of the axle motor is whether the braking function of the axle motor is normal. For example, it can be the corresponding braking time during braking operation, as well as parameters such as braking heat generation and heat dissipation; the axle motor state data is collected through the axle motor module, and the state data of the axle motor can be the angle data of the axle motor, whether the temperature during operation is abnormal, the lubrication degree between the shaft contact parts, etc.; the acceleration data is collected through the acceleration module, and the acceleration data can be the maximum acceleration that the centrifuge can reach during operation, the duration of the acceleration, and when making a safety judgment, the running state of the current centrifuge can be judged based on the comprehensive acceleration data and other data. The first integration module integrates various data collected by the main arm slave station 101. In the embodiments of the present invention, the types of each parameter and the data integration method are not limited, and those skilled in the art can determine according to actual needs.

[0050] As an alternative embodiment of the present invention, the slave main arm 101 further includes: a first analysis module for analyzing the main arm data to obtain a main arm data analysis result; and a first execution module for performing corresponding main arm safety measures based on the main arm data analysis result.

[0051] Exemplarily, the first analysis module analyzes through the integrated main arm data to determine whether the operation of the slave main arm 101 is abnormal. For example, within the same time period, when the axis brake data is not within the normal operating range, the first integration module can determine the specific cause of the axis brake abnormality based on whether the corresponding associated data (the data corresponding to the weekly brake data can be whether the acceleration data matches, etc.) is abnormal. The first execution module performs corresponding operations according to the analysis result of the first analysis module to eliminate the corresponding abnormal data. The embodiments of the present invention do not limit the various analysis methods, and those skilled in the art can determine according to actual needs.

[0053] Exemplarily, the slave cockpit 102 collects the balance state data of the cockpit through the second balance module, where the balance state data of the cockpit is the balance parameter during the operation of the cockpit, which can be the angle data of the cockpit during the operation, etc.; the axial acceleration data of the slave cockpit 102 is collected through the second acceleration module, and the acceleration data of the cockpit is the centrifugal acceleration data suffered by the subject during the operation of the centrifuge, etc.; the pressure of the air gas in the slave cockpit 102 is collected through the pressure module (when the subject is performing centrifugal training, a certain air pressure needs to be added); the physiological data (electrocardiogram, ear pulse, respiration, etc.) and state data (voice, facial expression) of the subject during centrifugal training are collected through the subject module to ensure the safety of the subject during centrifugal training to prevent harm caused by syncope due to high load. The second integration module integrates the collected data in a certain manner, and the specific integration method can be integration by time or integration by data type. The embodiments of the present invention do not limit the various data parameter types and data integration methods, and those skilled in the art can determine according to actual needs.

[0055] Exemplarily, the second analysis module analyzes through the integrated cockpit data to determine whether the operation of the cockpit slave station 102 is abnormal. For example, the training status of the subject can be determined according to the physiological characteristics of the subject. If the physiological data of the subject is not within the set threshold or information such as a painful facial expression appears, operations such as reducing the training intensity until training stops can be performed. The second execution module performs corresponding operations according to the analysis result of the second analysis module to eliminate the corresponding abnormal data. The embodiments of the present invention do not limit the analysis methods, and those skilled in the art can determine according to actual needs.

[0056] As an alternative embodiment of the present invention, the electrical slave station 103 includes: a power distribution module for collecting the power distribution data of the electrical slave station 103; a cooling module for collecting the cooling data of the electrical slave station 103; a compression module for collecting the compressed air data of the electrical slave station 103; a power supply module for collecting the power supply data of the electrical slave station 103; a frequency conversion module for collecting the frequency converter data of the electrical slave station 103; a motor module for collecting the main motor data of the electrical slave station 103; a main brake hydraulic module for collecting the hydraulic data of the electrical slave station 103; and a third integration module for integrating the power distribution data, cooling data, compressed air data, power supply data, frequency converter data, main motor data, and hydraulic data of the electrical slave station 103 into the electrical data.

[0057] Exemplarily, the electrical slave station 103 collects power distribution data through the power distribution module, where the power distribution data can be the operation data of each transformer and switch information, etc.; collects the temperature information corresponding to the working state of the cooling system (fan cooling system) of the electrical slave station 103 through the cooling module; collects the corresponding data information of the air compression module in the electrical slave station 103 through the compression module, which can be the set air compression value and outlet pressure information, etc.; collects the information of the power supply equipment through the power supply module, where the information of the power supply equipment can be the output rated voltage, current information, etc.; collects the status of the corresponding frequency converter and water temperature, etc. through the frequency conversion module; and collects the hydraulic data of the electrical slave station 103 through the main brake hydraulic module, where the hydraulic data can be hydraulic oil pressure, hydraulic oil volume, etc. The third integration module integrates the collected information in a certain manner.

[0058] As an alternative embodiment of the present invention, the electrical slave station 103 further includes: a third analysis module for analyzing the electrical data to obtain an electrical data analysis result; and a third execution module for performing corresponding electrical safety measures based on the electrical data analysis result.

[0059] Exemplarily, the third analysis module analyzes through the integrated electrical data to determine whether the operation of the electrical slave station 103 is abnormal. The third execution module performs corresponding operations according to the analysis result of the third analysis module to eliminate the corresponding abnormal data. The embodiments of the present invention do not limit the analysis methods, and those skilled in the art can determine according to actual needs.

[0060] As an alternative embodiment of the present invention, the centrifuge safety monitoring system further includes: a safety monitoring display module for displaying the main arm data, cockpit data, and electrical data of the centrifuge safety monitoring system, and at least one operable mode for instructing the safety master station 104 to perform safety operations corresponding to the analysis result; and a driving module for providing power for the centrifuge safety monitoring system. In practical applications, the safety monitoring display module can implement its functions through a display.

[0061] Exemplarily, the safety monitoring display module can display the composition and connection of the modules in each slave station and the network connection of the safety monitoring system, facilitating engineering operators to always grasp the operation status of each slave station and quickly locate the fault points. Integrating key monitoring information onto a main page is clearer and more convenient for operators to focus on monitoring. After the centrifuge is powered on, data can be collected in real time, the status of each monitoring point can be displayed, and when an alarm or fault occurs, it will be immediately displayed in red and enter the corresponding processing process. Fault and alarm information is stored and displayed in a list for easy retrieval and query. The operable mode provides a manual operation mode for the centrifuge. When maintenance is required, this mode can be switched to quickly perform relevant operations, such as switching the brake system, switching the compressed air system, switching the projection, resetting the roll and pitch axes, etc., improving the working efficiency of the safety system. The embodiments of the present invention do not limit the specific form of the operable mode, and those skilled in the art can determine according to actual needs.

[0063] Step 201: Obtain the self-check data before the start of the centrifuge safety monitoring system.

[0064] Exemplarily, before running the centrifuge, a self-check is performed on the centrifuge safety monitoring system to check the status of each part of the centrifuge and obtain corresponding self-check data, which may include: a. Checking the parameters of the centrifuge body, such as system balance, cabin balance, main motor status, drive PLC status, network status, brake system oil pressure, compressed air system status, frequency converter status, UPS status, etc.; b. Checking the external environment of the centrifuge, such as whether the door of the centrifuge rotation hall is locked and whether there are foreign objects in the hall (obtained through video monitoring); c. Checking the status of the subject, such as whether the subject's voice communication, video communication, and physiological signals are normal. The number of types of self-check data in the embodiments of the present invention is not limited, and those skilled in the art can determine it according to actual needs.

[0065] Step 202: Determine whether the self-check data is abnormal.

[0066] Step 203: If the self-check data is normal, start the centrifuge safety monitoring system, obtain the main arm data, cabin data, and electrical data of the safety master station of the centrifuge safety monitoring system, and analyze whether the centrifuge safety monitoring system is operating normally based on the main arm data, cabin data, and electrical data.

[0067] Exemplarily, during operation, the above signals are continuously monitored, and at the same time, the centrifuge operating load and load growth rate, and the subject's physiological signals and facial expressions (through video monitoring) are monitored in real time. If the subject's signals are abnormal, a medical shutdown operation is performed. If a fault occurs, the system determines whether the abnormality will immediately cause equipment damage or personal injury according to the logic matrix. If the judgment is no, an alarm message is displayed and the centrifuge continues to run. After the operation of this curve is completed, the next step of the operation can only be continued after the fault is eliminated. For the specific abnormal handling process, see the analysis method of the safety master station in the above system embodiments. For the specific monitoring process, see Figure 3 。

[0068] The centrifuge abnormality handling method provided by the present invention includes obtaining the self-check data before the start of the centrifuge safety monitoring system, and determining whether the self-check data is abnormal; if the self-check data is normal, starting the centrifuge safety monitoring system, obtaining the main arm data, cabin data, and electrical data of the safety master station of the centrifuge safety monitoring system, and analyzing whether the centrifuge safety monitoring system is operating normally based on the main arm data, cabin data, and electrical data.

[0069] As an optional implementation manner of the present invention, the centrifuge abnormality handling method further includes: if the self-check data is abnormal, generating a fault handling measure based on the self-check data and giving an alarm.

[0070] Exemplarily, if an abnormality occurs during the self-check process, it is judged as an alarm or a fault according to the fault level, and the corresponding processing flow is started. If it is at the alarm level, a prompt message is given without affecting the further operation of the centrifuge, and the system enters the standby state. If it is at the fault level, the centrifuge cannot be operated until the fault is eliminated.
