The following describes the scheme provided in the present specification with reference to the drawings.
In a first aspect, an embodiment of the present invention provides a testing system for a data storage device of a ventilator.
Referring to fig. 1, a test system provided in an embodiment of the present invention includes: main control device, heat abstractor and monitoring device, wherein:
the main control device is connected with the data storage device and the controller of the breathing machine and is used for: testing the data storage device by adopting a plurality of test modes, generating a test report after the test is completed, and sending a report generation notice to a controller of the breathing machine after the test report is generated, so that the controller sends the test report to a cloud platform of the breathing machine to update configuration parameters of the cloud platform; the data storage device is used for storing fault data generated in the operation process of each functional module of the breathing machine and configuration data sent to the breathing machine by the cloud platform;
the monitoring device is connected with the main control device and the heat dissipation device and is used for: acquiring state data of the data storage device in the testing process from the main control device according to a preset time interval, and sending the state data to the heat dissipation device; wherein the status data includes current test mode and power consumption data;
The heat dissipation device is used for: and when the state data is received, predicting the current internal temperature of the data storage device according to the state data, and carrying out heat dissipation treatment on the data storage device according to the current internal temperature and a preset internal temperature upper limit.
It is understood that the data storage device to be tested is connected in the master device prior to testing. In the testing process by using the testing system, the main control device adopts a plurality of testing modes to test the data storage device, wherein the testing modes can comprise a single read-write erasing testing mode, a read-write mode with a certain mixing proportion and the like, and can also be other modes. The master device will test in these modes one by one, thereby enabling testing of the data storage device in a number of ways.
After the test is completed, the main control device generates a test report according to the test condition, and then informs the controller of the breathing machine, and after the controller of the breathing machine receives the notification, the controller of the breathing machine can send the test report to the cloud platform of the breathing machine, so that the cloud platform can know the test condition, and further provide a reference for updating configuration parameters.
The data storage device of the breathing machine is used for storing various operation data generated in the operation process of each functional module of the breathing machine and configuration data sent to the breathing machine by the cloud platform, and certainly, software update packages and the like sent to the breathing machine by the cloud platform can also be stored. The data storage device generates corresponding metadata when data processing is performed, and the metadata is also stored in the data storage device.
In order to reduce the interference caused by high temperature, the embodiment of the invention adopts the monitoring device and the heat dissipation device, wherein the monitoring device can acquire the state data generated by the data storage device in the test process according to a certain time interval and then send the state data to the heat dissipation device, and the heat dissipation device can predict the temperature inside the data storage device according to the state data so as to judge whether the current internal temperature exceeds the preset upper limit of the internal temperature and needs heat dissipation treatment when the current internal temperature exceeds the upper limit. In this way, the internal temperature of the data storage device can be controlled within a certain range, thereby ensuring the reliability of the test procedure.
The data storage device stores the operation data, fault data, configuration parameters and system software packages of the breathing machine, and also can store the breathing state data of the patient, so that the configuration parameters of the breathing machine can be further adjusted according to the breathing state data of the patient. The respiratory state data of the patient during the treatment plays an important role, so the reliability of the data storage device is critical.
In specific implementations, the master device may also be configured to: when the test mode is switched in the test process, a mode switching notification is sent to the monitoring device; correspondingly, the monitoring device is further used for: when the mode switching notification is received, state data of the data storage device in the testing process is obtained from the main control device, and the state data is sent to the heat dissipation device, so that the heat dissipation device dissipates heat of the data storage device according to the state data.
That is, when the main control device switches the test mode in the test process, the monitoring module needs to be notified immediately, and after receiving the notification, the monitoring module can acquire the current state data of the data storage device in the test process immediately, and then send the current state data to the heat dissipation device, and the heat dissipation device performs heat dissipation treatment on the data storage device immediately.
It will be appreciated that the heat generated by the data storage device may be different in different test modes, and thus the degree of heat dissipation required in different test modes may be different, for example, the heat generated by the data storage device may be less in a certain test mode, and the heat dissipation capacity of the heat dissipation measures taken at this time may be lower. In a certain test mode, the data storage device generates more heat, and the heat dissipation capacity of the heat dissipation measures adopted at the moment needs to be higher. Therefore, when the test mode is switched, the corresponding heat dissipation measures are required to be switched, so that the method is suitable for different test modes in time.
Further, the heat dissipation device may be specifically configured to: calculating the current internal temperature using a first calculation formula comprising:
Tin＝q*√P+Tk
wherein Tin is the current internal temperature, P is the power consumption data, tk is the corrected temperature, q is the state representation value of the data storage device in the current test mode, and V is an arithmetic square root symbol.
It is appreciated that the heat sink employs the first computational prediction of the current internal temperature of the data storage device, and that a number of factors, such as test patterns, power consumption data, etc., need to be considered in predicting the current internal temperature. In the first calculation formula, P represents power consumption, and the higher the power consumption is, the higher the current internal temperature of the data storage device is. a represents a state representation value corresponding to a test mode, and the state representation values of the data storage device in the test mode are different, so that the influence of different test modes on the data storage device can be reflected, the larger the influence is, the higher the q value is, and the higher the internal temperature is. Tk is a corrected temperature, a specific value of the corrected temperature can be obtained through calibration in an actual scene, and specific values of the corrected temperature can be different for different types of data storage devices.
Further, the state representation value may be specifically calculated by using a second calculation formula, where the second calculation formula includes:
q＝e*(1/r)*C*Tf
e is the data exchange rate in the current test mode, wherein the data exchange rate is the data exchange amount between the data storage device and external equipment in unit time; c is the testing complexity level under different testing modes, and the different testing modes correspond to different testing complexity levels; r is the heat exchange capacity level of the data storage device and the external environment in the current test mode; tf is the ambient temperature.
It is understood that e represents the amount of data exchange between the data storage device and the external device (e.g., external storage device) per unit time in a certain test mode, the larger e, the larger q. C is the complexity corresponding to different test modes, the test flow of a certain test mode is complex, C is higher, the test flow is simpler, and C is smaller. r represents the heat exchange capacity of the data storage device and the external device in the test mode, and q is smaller as the heat exchange capacity is stronger. And meanwhile, the environment temperature is also considered, and the higher the environment temperature is, the higher q is. It can be seen that the second calculation formula may specifically characterize the test state of the data storage device in different test modes.
Wherein, main control device, heat abstractor etc. can adopt multiple structural style to realize, provide an optional structural style below: the main control device comprises a semi-closed cube shell made of metal and a PCB (printed circuit board) arranged on the opening side of the cube shell, an interface for connecting the data storage device is arranged on the PCB, and a program for testing the data storage device is arranged on the PCB; correspondingly, the heat dissipation module comprises a fan arranged inside the cube shell and heat absorption plates arranged on the inner side walls of the cube shell; when the data storage device is connected with the PCB through the interface, the outer surface of the data storage device is attached to the heat absorption plate in a zero-clearance mode.
The cube shell is open on one surface and made of metal, so that heat dissipation is facilitated. The open side is provided with the PCB board, and the PCB board can be connected with the data storage device through the interface, and the PCB board is provided with a test program which can be executed to test in a plurality of test modes, generate a test report, and inform a controller of the breathing machine and the like.
The heat dissipation module comprises a fan arranged inside the cube shell, and when the internal temperature of the data storage device is higher, the fan can be controlled to work at a higher rotating speed. And when the internal temperature of the data storage device is lower, the fan can be controlled to work at a lower rotating speed or stop working. The heat dissipation module further comprises a heat absorption plate arranged on the inner side wall, and when the data storage device is connected with the PCB, the outer surface of the data storage device is just attached to the heat absorption plate in a zero-clearance mode. When zero clearance is pasted, no air exists between the data storage device and the heat absorption plate, and the heat conduction effect can be greatly improved.
In order to realize zero-clearance fit, locking devices can be arranged on four sides of the data storage device, and after the data storage device is connected with the PCB, the data storage device can be locked on the inner side wall of the cube shell through the locking devices around, so that zero-clearance fit is realized.
The heat absorption plate comprises a first heat absorption part, a second heat absorption part, a U-shaped heat pipe part and a heat conduction pad; wherein: the first heat absorption part is in contact with one surface of the U-shaped heat pipe part, the second heat absorption part is in contact with the other surface of the U-shaped heat pipe part, the heat conduction pad is clamped between the second heat absorption part and the inner side wall, and the first heat absorption part is used for being in zero-clearance fit with the outer surface of the data storage device; and a supporting part is arranged between the first heat absorption part and the second heat absorption part so as to prevent the first heat absorption part and the second heat absorption part from extruding the U-shaped heat absorption part.
That is, the order of the respective components in the absorber plate is in turn: the heat pipe comprises a first heat absorption part, a U-shaped heat pipe part, a second heat absorption part and a heat conduction pad, wherein the first heat absorption part is contacted with the outer surface of the data storage device, and the heat conduction pad is contacted with the inner side wall of the cube shell. Because the U-shaped heat pipe component is easy to be extruded and deformed, in order to avoid the extrusion of the first heat absorption component and the second heat absorption component to the U-shaped heat pipe component, a supporting component is arranged between the first heat absorption component and the second heat absorption component, so that the U-shaped heat pipe component can be prevented from being deformed, and the stability and the reliability of the heat absorption plate are improved.
Therefore, in the heat dissipation device provided by the embodiment of the invention, heat generated in the testing process of the data storage device is dissipated through the fan and the heat absorption plate, so that the internal temperature of the data storage device is reduced, and the reliability and the effectiveness of the testing process are ensured.
In specific implementation, the data storage device for which the embodiment of the present invention performs the test may be various, and the structure of one of the data storage devices is described below:
the data storage device may include M logic module groups, each logic module group includes L logic modules, each logic module includes a first structure, a second structure, and a third structure, each structure includes W blocks, the number of the blocks included in the first structure, the second structure, and the third structure are the same and correspond to each other one by one, a first physical page in each block includes N logic pages, and each logic page includes a first unit, a second unit, and a third unit; storing identification information corresponding to each logical page in a first unit of each logical page of a first physical page of each block; storing one metadata of each logical page in the first physical page of each block in the second unit of the block, wherein the N logical pages of the first physical page of the block and the N metadata of the block are in one-to-one correspondence, and the metadata stored in the corresponding logical pages in the first physical pages in the corresponding blocks of the first structure, the second structure and the third structure are the same; the third unit of each logical page of the first physical page of each block stores metadata of corresponding blocks in all other logical modules except the logical module of the block in the logical module group where the block is located; the other physical pages in each block, except the first physical page, are used for storing the fault data and the configuration data; wherein M, N, L and W are positive integers.
For example, the data storage device includes 3 logic module groups, referring to fig. 2, each logic module group includes 2 logic modules, and each logic module includes a first structure, a second structure, and a third structure, and the number of blocks included in the three structures is the same and corresponds to one. Each block comprises a plurality of physical pages, wherein 4 logical pages are contained in a first physical page of the block, and each logical page is divided into a first unit, a second unit and a third unit, and the information stored in the three units is different, wherein the information stored in the first unit is identification information corresponding to the located logical page, the information stored in the second unit is one metadata of the located block, and the four logical pages are contained in the first physical page of one block, so that 4 metadata of the located block can be stored in the first physical page of one block. The metadata stored in the corresponding logical pages in the first physical pages in the corresponding blocks in the first, second and third structures are identical because the first, second and third structures are used synchronously, i.e. one block is used, when data storage is performed using the data storage device, and the metadata thus generated are identical. The information stored in the third unit is metadata of the corresponding block in each of the other logical modules except the logical module where the block is located in the logical module group where the block is located. While other physical pages than the first physical page in a block are used to store fault data, configuration data, operational data, soft datagram, etc.
It can be seen that different information is stored in different units in a logical page, one unit stores identification information of the logical page, one unit stores one metadata of a block where the unit is located, and one unit stores one metadata of a corresponding block of other logical modules in the group of logical modules where the unit is located. When an abnormal situation occurs, the data before the abnormal situation occurs can be recovered according to the storage information in the first physical page for each unit in each logical page. Wherein the metadata may include: the type of block, read-write error information, etc.
When abnormal power failure occurs or data is received but not yet obtained and stored, metadata stored in each logical page can be read through scanning each logical page in the first physical page of the block, and data recovery is carried out through the metadata, so that information before power failure is quickly recovered, data loss of a user is reduced, the data storage device continues to work, and subsequent use is not affected.
In particular implementations, the cloud platform may be configured to: when the test report is received, determining the working state of the data storage device according to the test report; if the working state is qualified, acquiring fault data of the breathing machine; calculating the aging speed condition of the breathing machine according to the fault data; adjusting corresponding configuration parameters for the breathing machine according to the aging speed condition; sending the configuration parameters to the breathing machine so that a controller of the breathing machine stores the configuration data in the data storage device to cover the stored configuration parameters, and carrying out parameter adjustment on the breathing machine according to the stored configuration parameters;
The fault data comprise switching on and off fault data of a breathing machine, fault data of a humidifier in the breathing machine, fault data of a sensor in the breathing machine and fault of the fan in the breathing machine; the cloud platform is configured to calculate the aging speed condition using a third calculation formula, where the third calculation formula includes:
g 2 ＝[a1*(s1-x1)+a2*(s2-x2)+a3*(s3-x3)+a4*(s4-x4)] 2 /4
wherein g is the aging speed, s1 is the occurrence frequency of the switching on/off fault in the past month, x1 is the occurrence frequency of the switching on/off fault in the past year, and a1 is the weight of the switching on/off; s2 the occurrence frequency of the humidifier faults in the past month, x2 the occurrence frequency of the humidifier faults in the past year, and a2 the weight of the humidifier; s3 the frequency of occurrence of the sensor failure in the past month, x3 the frequency of occurrence of the sensor failure in the past year, a3 the weight of the sensor; s4, the occurrence frequency of the fan faults in the past month, x4 the occurrence frequency of the fan faults in the past year, and a4 the weight of the fan.
It can be appreciated that when the cloud platform receives the test report, the working state of the data storage device can be known according to the test report. If the operating state is not acceptable, a new data storage device may be updated by the ventilator. If the operating state is acceptable, further processing can be performed on the basis of the data storage device, for example, updating configuration parameters, updating system software and the like.
Aiming at updating the configuration parameters, the cloud platform calculates the aging speed condition of the breathing machine according to fault data generated by the breathing machine in the operation process, adjusts the corresponding configuration parameters according to the aging speed condition, and sends the adjusted configuration parameters to the breathing machine, so that a controller of the breathing machine can replace the old configuration parameters with the new configuration parameters, cover the old configuration parameters, and then carry out parameter adjustment according to the new configuration parameters.
In one embodiment, since a plurality of modules including switches, humidifiers, sensors, fans, etc. are included in the ventilator, the aging rate condition can be calculated from the failure data of these modules. In calculating the aging body, the aging of the ventilator may be significantly accelerated according to a third calculation formula in which the frequency of failures in the past year is taken as a basis, if the frequency of failures in the past month increases significantly. If the frequency of faults in the past month is not much different from the frequency of faults in the past year, the aging of the breathing machine is not obviously accelerated, and the aging speed is slow. It is understood that the aging speed of different functional modules has different degrees of influence on the aging speed of the ventilator, and thus different weights are set for the different functional modules.
It will be appreciated that the patient's spontaneous breathing level is generally considered in the case of the configuration parameters, and if the patient's spontaneous breathing level increases gradually during use of the ventilator, the ventilator configuration parameters will also need to be continually adjusted. In the invention, when the configuration parameters are adjusted, the aging speed condition of the breathing machine is considered, if the aging speed is too high, the adjusting frequency of the configuration parameters can be increased, and if the aging speed is relatively low, the current adjusting frequency of the configuration parameters can be kept unchanged. Besides updating the adjustment frequency, specific configuration parameters can be updated, for example, if the current aging speed is calculated to be faster through the third calculation formula, certain configuration parameters can be increased or decreased appropriately at this time, so that the configuration parameters are adapted to the aging speed of the breathing machine, and thus the reliability of the breathing machine can be improved.
It is worth noting that the breathing machine in the embodiment of the invention can be applied to epidemic prevention control, and the reliability of the test result can be ensured because the embodiment of the invention tests the data storage device in the breathing machine and controls the internal temperature of the data storage device in the test process. According to the test result, whether the data storage device of the current breathing machine needs to be replaced or not can be determined, and further the reliability of the breathing machine in the epidemic prevention use process can be guaranteed.
In a second aspect, an embodiment of the present invention provides a method for testing a data storage device of a ventilator, the method being implemented based on the test system provided in the first aspect, referring to fig. 2, the method including:
