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 performing heat dissipation treatment on the data storage device according to the current internal temperature and a preset internal temperature upper limit.
It will be appreciated that the data storage device to be tested is connected in the master device prior to testing. In the process of testing by using the test system, the main control device can test the data storage device by adopting a plurality of test modes, wherein the test modes can comprise a single read-write-erase test mode, a read-write mode with a certain mixing proportion and the like, and can also be other modes. The master control device adopts the modes to carry out testing one by one, thereby realizing the testing of the data storage device in multiple aspects.
After the test is completed, the main control device can generate a test report according to the test condition and further inform a 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 a cloud platform of the breathing machine, so that the cloud platform can know the test condition and further provide reference for updating the 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 can also be used for storing a software update package and the like sent to the breathing machine by the cloud platform. The data storage device generates corresponding metadata during data processing, 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 state data generated by the data storage device in the test process according to a certain time interval and further send the state data to the heat dissipation device, and the heat dissipation device can predict the temperature in the data storage device according to the state data so as to judge whether the current internal temperature exceeds the preset internal temperature upper limit or not, and heat dissipation treatment is needed when the 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 process.
The data storage device can store the breathing state data of the patient besides the operation data, the fault data, the configuration parameters and the system software package of the breathing machine, 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 process plays an important role, so the reliability of the data storage device is critical.
In specific implementation, the master control device may be further configured to: when the test mode is switched in the test process, sending a mode switching notice to the monitoring device; correspondingly, the monitoring device is further configured to: and when the mode switching notification is received, acquiring the state data of the data storage device in the testing process from the main control device, and sending the state data to the heat dissipation device so that the heat dissipation device can perform heat dissipation treatment on the data storage device according to the state data.
That is to say, when the master 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 processing on the data storage device immediately.
It can be understood that, in different test modes, the heat value of the data storage device may be different, so that the degree of heat dissipation required in different test modes is different, for example, in a certain test mode, the heat generated by the data storage device is less, and the heat dissipation capability of the heat dissipation measure adopted at this time may be lower. However, in a certain test mode, the data storage device generates a large amount of heat, and the heat dissipation capability of the heat dissipation measures adopted at this time needs to be high. Therefore, corresponding heat dissipation measures need to be switched when the test modes are switched, so that the test device can adapt to different test modes in real time.
Further, the heat dissipation device may be specifically configured to: calculating the current internal temperature using a first calculation formula, the first calculation formula including:
Tin＝q*√P+Tk
where Tin is the current internal temperature, P is the power consumption data, Tk is the correction temperature, q is a state representation value of the data storage device in the current test mode, and v is an arithmetic square root symbol.
It can be appreciated that the heat sink employs the first calculation formula to predict the current internal temperature of the data storage device, and a plurality of factors, such as test mode, power consumption data, etc., need to be considered when predicting the current internal temperature. In the first calculation formula, P represents power consumption, and an arithmetic square root operation is performed on the power consumption, and the higher the power consumption is, the higher the current internal temperature of the data storage device is. and a represents a state representation value corresponding to the test mode, the state representation values of the data storage device in the test mode are different and can reflect the influence of different test modes on the data storage device, and the larger the influence is, the higher the q value is, and the higher the internal temperature is at the moment. Tk is a correction temperature, and a specific value of the correction temperature may be obtained by calibration in an actual scene, and may be different for different types of data storage devices.
Further, the state characterizing value may specifically be calculated by using a second calculation formula, where the second calculation formula includes:
q＝e*(1/r)*C*Tf
wherein e is a data exchange rate in the current test mode, and the data exchange rate is the data exchange amount between the data storage device and the external equipment in unit time; c is the test complexity level under different test modes, and different test modes correspond to different test 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 an external device (e.g., an external storage device) per unit time in a certain test mode, and the larger e, the larger q. And C is the complexity corresponding to different test modes, and if the test flow of a certain test mode is more complex, C is higher, the test flow is simpler, and C is smaller. r represents the heat exchange capability of the data storage device and the external device in the test mode, and the stronger the heat exchange capability, the smaller q. Also considering the ambient temperature, the higher q. It can be seen that the second calculation formula can specifically characterize the test states of the data storage device in different test modes.
The main control device, the heat dissipation device and the like can be realized in various structural forms, and an optional structural form is provided as follows: the main control device comprises a semi-closed cubic shell made of metal and a PCB arranged on the opening side of the cubic shell, wherein the PCB is provided with an interface connected with the data storage device, and the PCB is provided with a program for testing the data storage device; correspondingly, the heat dissipation module comprises a fan arranged inside the cubic shell and heat absorption plates arranged on the inner side walls of the cubic 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.
Wherein, the cube casing is the one side is uncovered, and is the metal material, is convenient for like this dispel the heat. The PCB board is arranged on one side of the opening, the PCB board can be connected with a data storage device through an interface, a test program is arranged on the PCB board, the test program can execute testing in multiple test modes, a test report is generated, and a controller of the breathing machine is informed.
The heat dissipation module comprises a fan arranged inside the cubic shell, and when the internal temperature of the data storage device is high, the fan can be controlled to work at a high rotating speed. And when the internal temperature of the data storage device is low, the fan can be controlled to work or stop working at a low rotating speed. 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 the zero-clearance fit is carried out, air does not exist 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 fitting, 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 cubic shell through the surrounding locking devices, so that zero-clearance fitting 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 absorbing component is arranged in contact with one surface of the U-shaped heat pipe component, the second heat absorbing component is arranged in contact with the other surface of the U-shaped heat pipe component, the heat conducting pad is clamped between the second heat absorbing component and the inner side wall, and the first heat absorbing component is used for being attached to the outer surface of the data storage device in a zero-clearance mode; a supporting member is disposed between the first heat absorbing member and the second heat absorbing member to prevent the first heat absorbing member and the second heat absorbing member from pressing the U-shaped heat absorbing member.
That is, the order of the components in the absorber plate is, in turn: the heat absorption device comprises a first heat absorption component, a U-shaped heat pipe component, a second heat absorption component and a heat conduction pad, wherein the first heat absorption component is in contact with the outer surface of the data storage device, and the heat conduction pad is in contact with the inner side wall of the cubic shell. Because the U-shaped heat pipe part is easy to deform due to extrusion, in order to avoid the first heat absorbing part and the second heat absorbing part from extruding the U-shaped heat pipe part, the supporting part is arranged between the first heat absorbing part and the second heat absorbing part, so that the U-shaped heat pipe part can be prevented from deforming, and the stability and the reliability of the heat absorbing plate are improved.
Therefore, in the heat dissipation device in the embodiment of the invention, the heat generated in the test 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 effectiveness of the test process are ensured.
In specific implementation, the data storage devices for which the test of the embodiment of the present invention is performed may be various, and one of the structures of the data storage devices is described below:
the data storage device may include M logical module groups, each logical module group includes L logical modules, each logical module includes a first structure, a second structure, and a third structure, each structure includes W blocks, the number of blocks included in the first structure, the second structure, and the third structure is the same and corresponds to one another, a first physical page in each block includes N logical pages, and each logical 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 piece of metadata of each block in a second unit of each logical page of a first physical page of each block, wherein the N logical pages of the first physical page of the block correspond to the N metadata of the block in a one-to-one manner, and the metadata stored in the corresponding logical pages in the first physical page 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 a corresponding block in each of other logical modules except the logical module in which the block is located in the logical module group in which the block is located; the other physical pages except the first physical page in each block 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, and 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 is in one-to-one correspondence. The method comprises the steps that each block comprises a plurality of physical pages, a first physical page comprises 4 logical pages, each logical page is divided into a first unit, a second unit and a third unit, and 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 metadata of the located block, and the four logical pages in the first physical page of one block can store the 4 metadata of the located block in the first physical page of one block. The metadata stored in the corresponding logical page in the first physical page in the corresponding block in the first structure, the second structure and the third structure are the same, because the first structure, the second structure and the third structure are used synchronously, i.e. one block is used when the data storage device is used for data storage, and therefore the generated metadata is the same. The information stored in the third unit is metadata of a corresponding block in each other logical module except the logical module in the logical module group in which the block is located. And the other physical pages in a block except the first physical page are used to store failure data, configuration data, operational data, software datagrams, etc.
It can be seen that different units in a logical page store different information, one unit stores identification information of the logical page, one unit stores metadata of the block where the unit is located, and one unit stores metadata of corresponding blocks of other logical modules in the logical module group where the unit is located. When an abnormal condition occurs, the data before the abnormal condition occurs can be recovered according to the storage information of each unit in each logical page in the first physical page. Wherein the metadata may include: type of block, read-write error information, etc.
When abnormal power failure occurs, or when power failure notification is received but data is not received and stored, metadata stored in each logical page can be read through each logical page in the first physical page of the scanning block, data recovery is performed through the metadata, information before power failure is quickly recovered, data loss of a user is reduced, the data storage device continues to work, and follow-up 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 performing parameter adjustment on the breathing machine according to the stored configuration parameters;
wherein the fault data comprises on-off fault data of a ventilator, fault data of a humidifier in the ventilator, fault data of a sensor in the ventilator, and a ventilator fault in the ventilator; the cloud platform is configured to calculate the aging speed condition by 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 condition, s1 is the frequency of the on/off faults occurring in the past month, x1 is the frequency of the on/off faults occurring in the past year, and a1 is the weight of the on/off; s2 frequency of occurrence of humidifier malfunction over the past month, x2 frequency of occurrence of humidifier malfunction over the past year, a2 weight of the humidifier; s3 frequency of occurrence of the sensor failure over the past month, x3 frequency of occurrence of the sensor failure over the past year, a3 weight of the sensor; s4 frequency of occurrence of the fan failure in the past month, x4 frequency of occurrence of the fan failure in the past year, a4 weight of the fan.
It can be understood 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, the new data storage device may be replaced by the ventilator. If the operating state is acceptable, further processing may be performed on the basis of this data storage device, for example, updating of configuration parameters, updating of system software, and the like.
Aiming at the update of the configuration parameters, the cloud platform can calculate the aging speed condition of the breathing machine according to fault data generated in the operation process of the breathing machine, then adjust the corresponding configuration parameters according to the aging speed condition, and send the adjusted configuration parameters to the breathing machine, so that a controller of the breathing machine can replace old configuration parameters with new configuration parameters, cover the old configuration parameters, and then adjust the parameters according to the new configuration parameters.
In one embodiment, since a plurality of modules such as a switch, a humidifier, a sensor, a fan, etc. are included in the ventilator, the aging speed condition can be calculated from the fault data of the modules. The aging state can be calculated according to a third calculation formula, wherein the frequency of faults in the past year is taken as a basis, and if the frequency of faults in the past month is obviously increased, the aging of the breathing machine is obviously accelerated. And if the failure frequency in the past month is not much different from the failure frequency in the past year, the aging of the breathing machine is not accelerated obviously, and the aging speed is slow. It will be appreciated that the aging speed of different functional modules affects the aging speed of the ventilator to a different extent, and therefore different weights are set for different functional modules.
It will be appreciated that the patient's spontaneous breathing level is generally considered in the configuration of the ventilator, and that if the patient gradually increases in spontaneous breathing level during use of the ventilator, the ventilator configuration may need to be continually adjusted. In the invention, the aging speed condition of the breathing machine is also considered when the configuration parameters are adjusted, if the aging speed is too high, the adjusting frequency of the configuration parameters can be increased, and if the aging speed is slower, the current adjusting frequency of the configuration parameters can be kept unchanged. Besides updating the adjustment frequency, the specific configuration parameters may also be updated, for example, if the current aging speed calculated by the third calculation formula is faster, some configuration parameters may be increased or decreased appropriately to adapt to the aging speed of the ventilator, so as to improve the reliability of the ventilator.
It is worth noting that the respirator in the embodiment of the invention can be applied to epidemic prevention control, and because the embodiment of the invention tests the data storage device in the respirator and controls the internal temperature of the data storage device in the test process, the reliability of the test result can be ensured. According to the test result, whether the data storage device of the current respirator needs to be replaced or not can be determined, and the reliability of the respirator in the epidemic prevention use process can be further ensured.
