The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Example 1

The invention provides an interactive care billboard system, which comprises the following modules:

the interactive care sign system of the present invention comprises at least a care sign application and an Android system, the care sign application running on the Android system, in a more specific embodiment, the interactive care sign system comprises a processor, a memory, a display, an Android system, and a care sign application. The nursing billboard application is shown in fig. 1, and in one embodiment, the nursing billboard application is an APP and mainly comprises four parts, wherein the first part is an APP profile part, the second part is patient statistics information, the third part is patient profile information, and the fourth part is an on-duty doctor and on-duty nurse part; the third part is composed of a plurality of patient profile units, clicking or remote control selects patient profile information, as shown in fig. 1, the remote control or touching number 10 will display the selection, when the determination or double clicking touch screen on the remote control is clicked, the third part jumps to the patient detailed information page, which includes but is not limited to personal information of the patient, doctor's advice, nursing record, etc. The patient profile unit is a patient Item for displaying summary information of the patient, such as patient bed number, patient name, patient age, stay in hospital, allergy history, diet, etc.

In the operation of the care sign application, since each patient Item displays the same content, the heap memory occupied by each patient Item is the same, i.e., it is mainly related to the number of patient items, and the patient items generally exist for the same time as the patient is in hospital, usually for several days. In garbage collection (GC, garbage Collection), objects corresponding to patient items are put into old age (oldce) after several Young GCs, and each time Young GC, objects corresponding to patient items move between survivinr 0 and survivinr 1, resulting in lower efficiency.

According to the invention, after the profile information of one patient is added, namely one patient Item is added, and the objects corresponding to the patient Item are determined, the objects are directly added to the old age, so that repeated copying between the survivinr 1 and the Servivor1 is avoided. Similarly, when deleting one patient Item, the corresponding object is directly deleted from the aged without GC, so that the management efficiency of the heap area is improved.

GC is divided into Young GC, major GC and Full GC, wherein Young GC is used for recycling Young generation garbage, major GC is used for recycling old generation garbage, and Full GC is used for recycling garbage in a heap area and also used for recycling garbage in a method area of a memory. Since the time consumed by the Major GC and the Full GC is several times that of the Young GC, STW (Stop The World) appears in the Major GC and the Full GC, and if the STW time of the Major GC and the Full GC is too long, the user may feel a noticeable click. When the STW time exceeds the threshold, the heap memory area bound to the patient is skipped when the Major GC or Full GC is performed, so that the STW time can be reduced.

When the user views the detailed information of the patient, the detailed information of the patient comprises more contents, the occupied heap memory is larger, and when the STW exceeds the threshold value, the invention further reconfigures the heap memory according to the change condition of the heap memory after the Major GC or the Full GC.

When adding or deleting patient profile information, there are other objects besides the object corresponding to the patient Item, for example, the object instantiated by the adding operation process or the object instantiated by the deleting operation process, and other objects related to the instantiated object, these objects will not be permanently replaced after adding or deleting one patient profile information, and will be removed from the Young generation after several Young GCs, which requires the object corresponding to the patient Item to be stored in the old generation in the heap for a long time. In a specific embodiment, the first preset method increases or recovers heap memory, specifically:

The present invention configures a heap memory area for each patient profile information, that is, each patient Item, as shown in fig. 3, and stores the object corresponding to the patient Item in the persistent generation, wherein the object corresponding to the patient Item is the object of the same life cycle as the patient Item, and is created along with the creation of the patient Item, and is deleted along with the deletion of the patient Item. When the patient is detected to be deleted from the nursing billboard application program, the Young GC is triggered once, so that objects which possibly exist in the Young generation and correspond to the patient are deleted, active recycling of the Young GC is realized, and in addition, the heap memory area bound with the patient is recycled. The problem of STW time course at one time of Major GC or Full GC is avoided. The heap memory region is a block of contiguous regions. In one embodiment, the object corresponding to the patient refers to an object corresponding to the patient Item, and the object is the same as the life cycle of the patient Item.

When the Major GC or Full GC occurs, most of the cases are due to insufficient storage space in the heap, and especially when medical staff views patient details, a plurality of patient details are also viewed later, and if the heap storage space is insufficient, each view details will be jammed. The heap memory configured by the JVM is adjusted according to the heap memory change condition, specifically:

When medical staff looks at details, two cases occur due to the action of the Major GC or the Full GC, the first is that the Major GC or the Full GC is performed, but the first is that the objects in the old are still increased, that is, the objects stored in the old are mostly reachable by GC Roots, and the second is that the objects stored in the old are decreased after the Major GC or the Full GC. In the first case, OOM is very likely to occur if no adjustment is made to the heap memory.

Since the occupied space of the heap memory is increased or decreased after the details are checked and the Major GC or the Full GC is judged, if the occupied space is decreased, the OOM is not generated this time, the OOM is not generated next time, and the heap memory is not required to be adjusted.

However, if the occupied space of the senior citizen after the Major GC or the Full GC increases, if detailed information of a plurality of patients is continuously checked, the OOM is likely to occur, and in order to prevent the OOM, the heap memory needs to be adjusted, specifically, the heap memory configured by the JVM is increased according to the number of patients, the increased occupied space, and the heap memory size corresponding to each Item. In a specific embodiment, the adjusting the heap memory configured by the JVM according to the patient number, the H, and the heap memory size specifically includes:

Calculating increased age size H _add The method comprises the steps of carrying out a first treatment on the surface of the Wherein N is _patien Representing the number of patients, heap _patien Representing the stackMemory size, heap Memory age size, memory for JVM configuration _idle And the memory idle rate of the equipment where the nursing board application program is located is set.

Since the old age has not only the object bound with the user but also other objects, the space allocated for the old age and half of the first occupied space are set as judgment standards, so that the OOM is prevented, and attacks are reserved for other objects, when

When the elderly age is increased, the Memory is replaced _idle ·N _patien H, e.g. N _patien H is 500M, and the memory idle rate of the device is 40%, 400M is added. In another embodiment, set H _add The range of (2) is related to the memory of the device where the Android system is located, e.g. H _add Is (0, memory 0.05)]The operation fault of the Android system caused by excessive memory allocation to the old age is avoided, and the calculated H is calculated _add When the above range is exceeded, it is set as the maximum value of the range

In another embodiment, the adjusting the heap memory configured by the JVM according to the patient number, the H, and the heap memory size specifically includes: if the set age size-patient number x (H + the heap memory size) is less than a preset value, the age space of patient number x H is increased. In one embodiment, increasing the older age refers to maintaining the size of the younger age unchanged, increasing the older age, rather than assigning the younger age to the older age.

In a specific embodiment, the detail viewing module further includes a Young age threshold adjustment module for adjusting the Young age threshold according to the number of times Young GC occurs when the profile information of the first patient is added to the care sign application. Frequent occurrences of Young GCs also affect performance, and in one embodiment, a step value is set, and Young age thresholds are adjusted based on the number of Young GCs and the step value. For example, set the step value as: 5,10,15 when adding profile information for a patient, i.e. adding an Item in the care sign application, 14 Young GCs occur, the next time the age threshold is adjusted to 10, and so on.
