Description

Networking method of central monitoring system and medical equipment
Technical Field
The invention relates to the technical field of central monitoring systems, in particular to a networking method and medical equipment of a central monitoring system.
Background
Networking of the central monitoring system as shown in fig. 1, after the monitor is connected to the central station, the central station consumes certain resources for processing real-time monitoring data and services sent by the monitor. Thus, when a new monitor subsequently requests access to the central station, the central station needs to determine whether the new monitor is accessible. That is, the central monitoring system needs to control the number of monitors that are accessible at the central station when networking.
For example, the number of monitors accessible at the central station may be in several ways: (1) fixed number: the method comprises the steps that the maximum number of monitors allowed to be accessed is preset on a central station, and when the monitors request to be accessed, the central station can judge whether the number of the monitors currently accessed reaches the set maximum number or not, so that available resources of the central station are ensured; (2) countless limitations but manual confirmation: the maximum number of monitors which are allowed to be accessed is not limited on the central station, but when the monitors request to be accessed, the central station prompts that the monitors need to be accessed, and then whether the monitors are allowed to be accessed is manually confirmed; (3) fixed number and need manual confirmation: the method comprises the steps that the maximum number of monitors allowed to be accessed is preset on a central station, when the monitors request to be accessed, the central station prompts that the monitors need to be accessed, then whether the monitors are allowed to be accessed is confirmed manually, and when the monitors are confirmed to be allowed to be accessed manually, whether the number of the monitors which are accessed currently reaches the set maximum number is judged.
However, the above 3 schemes all have a certain problem, and in the first scheme, since the set maximum number is the tested engineering value, the number of accessed devices and the stability of the system can be ensured, but the maximum number is generally conservative, and even if the central station can also access more devices, the system resource can be wasted under the influence of the threshold value; in the second scheme, the number of monitors currently accessed by the central station is not known during manual confirmation, so that the system is allowed to be accessed to the monitors again under the condition that the central station is already in high-load operation, the overload operation of the system is caused, and the stability of the system is further influenced; in the third solution, the maximum number of monitors is set, which may also result in waste of resources.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. 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.
Fig. 1 shows an alternative application scenario of the central monitoring system according to an embodiment of the present invention. As shown in fig. 1, the central station 2, the management server and the monitors are allowed to be one network segment or different network segments, but the nodes are mutually communicated. The management server is used for completing configuration of the central station, manual management of the monitor, checking of patient monitoring data and the like.
The networking is that the monitor is accessed to the central station, and whether the central station allows the monitor to be accessed, in this embodiment, a dynamic networking mode is adopted. Specifically, the networking method of the central monitoring system utilizes the real-time system resource utilization rate of each central station to carry out networking, namely, each central station in the central monitoring system firstly acquires the respective system resource utilization rate and determines the respective running state based on the system resource utilization rate; and broadcasting the running state, so that the monitor can know the running state of each central station in the central monitoring system, and the central station with smaller load can be screened out from the monitoring system to access the monitoring system based on the running state of each central station. Therefore, the networking method of the central monitoring system in the embodiment of the invention is a dynamic access process, and networking is performed based on the real-time system resource utilization rate of the central station, so that the stability of the central monitoring system and the utilization rate of the system resource can be ensured.
In accordance with an embodiment of the present invention, a networking method embodiment of a central monitoring system is provided, it being noted that the steps shown in the flowchart of the figures may be performed in a computer system, such as a set of computer executable instructions, and that, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order other than that shown or described herein.
In this embodiment, a networking method of a central monitoring system is provided, which may be used in the central station, and fig. 2 is a flowchart of the networking method of the central monitoring system according to an embodiment of the present invention, as shown in fig. 2, where the flowchart includes the following steps:
s11, acquiring the local system resource utilization rate.
The system resource utilization rate comprises at least one of CPU utilization rate, memory utilization rate and network bandwidth utilization rate.
During the networking process, all central stations in the central monitoring system acquire respective system resource utilization rates at regular intervals, for example, the system resource utilization rates can be 3S, 5S, 10S or the like. The time interval for specifically acquiring the local system resource utilization rate can be set correspondingly according to the actual situation, and the numerical value of the time interval is not limited.
A system operational status monitoring service may be initiated at the central station and periodically run in a recurring manner. That is, the detection service program circularly detects the use condition of the CPU, the memory, and the network on the current operating system in the central station, for example, once in 5S.
The central station may create a data table for storing local system resource utilization. For example, after the local system resource utilization is obtained, the newly obtained system resource utilization is replaced with the existing system resource utilization in the data table, so as to update the data table, so that the system resource utilization in the data table is the current system resource utilization of the central station. Of course, the central station may also use other forms to store the obtained system resource utilization, and the storage form is not limited in any way.
The system resource utilization rate obtained by the central station can be CPU utilization rate, memory utilization rate, network bandwidth utilization rate or any combination of the three. Of course, other attributes local to the device may be included, etc.
S12, determining a local running state based on the local system resource utilization rate.
The central station may determine a local operating state using the obtained system resource utilization, where the local operating state may be whether a new monitor is currently allowed to be accessed locally, or may indicate that the current system load of the central station is low, medium, high, or the like.
The obtained resource utilization may be compared with various thresholds to determine a local operating state. For example, 3 thresholds may be set corresponding to respective system resource utilization rates, corresponding to low, medium, and high utilization rates, respectively. Then, accordingly, the local operating state may be determined as low, medium, or high system load. Or corresponding to each system resource rate, setting corresponding 1 threshold value, and accordingly, determining whether to allow access to a new monitor locally.
The corresponding threshold value may be determined based on empirical values, and may need to be evaluated based on the risk that the central station user and the central monitoring system may be exposed to.
S13, broadcasting the local running state to a network of the central monitoring system.
After the central station determines the local operating state in S12, the operating state may be broadcast to the network of the central monitoring system. This is because each device in the central monitoring system is in the same local area network, and each monitor in the local area network can acquire the operating status of each central station after the central station broadcasts the operating status to the network of the central monitoring system.
The local running state broadcasted by the central station can be whether the local allows to access a new monitor or not, or can be that the local current load is low, medium or high; the two conditions can also be respectively combined with the utilization rate of system resources and the like, namely, whether the local running state allows to be accessed to a new monitor or not and the utilization rate of the local system resources; alternatively, the local operating state is the local current load and the local system resource utilization.
S14, receiving the access request determined by the monitor based on all the received operation states.
The central station in the central monitoring system monitors the access request of the monitor in real time so as to ensure that the access request of the monitor can be processed in time. Specifically, the access request is screened by the monitor after the monitor receives the operation states of all the central stations, and the central station with the lowest current load can be screened, or the central station which is allowed to be accessed to the monitor currently can be screened. Which will be described in detail later.
S15, according to the local running state, whether the monitor is allowed to be accessed to the local or not is confirmed.
After receiving the access request of the monitor, the central station combines the local running state to determine whether to allow the access of the monitor. This step will be described in detail later.
According to the networking method of the central monitoring system, the local running state is determined by utilizing the local system resource utilization rate, and the local running state is broadcasted, namely when a new monitor is connected to the central station, the new monitor is used for determining a proper central station to send an access request based on the received running states of all the central stations; therefore, the networking method is based on the real-time system resource utilization rate of the central station, and when the load of a certain central station is heavy, the monitor is not allowed to be accessed, so that the system downtime caused by overload operation of the central station can be avoided, and the stability of the central monitoring system can be ensured; when the load of a certain central station is smaller, the monitor is allowed to be accessed, and the resource utilization rate of the central monitoring system is improved.
In this embodiment, a networking method of a central monitoring system is provided, which may be used in the central station, and fig. 3 is a flowchart of the networking method of the central monitoring system according to an embodiment of the present invention, as shown in fig. 3, where the flowchart includes the following steps:
s21, acquiring the local system resource utilization rate.
The system resource utilization rate comprises at least one of CPU utilization rate, memory utilization rate and network bandwidth utilization rate.
In this embodiment, the system resource utilization rate is described by taking as an example the CPU utilization rate, the memory utilization rate, and the network bandwidth utilization rate. Please refer to S11 in the embodiment shown in fig. 2, which is not described herein.
S22, determining a local running state based on the local system resource utilization rate.
The central station determines the local operation state by using the local system resource utilization rate obtained in S21. In this embodiment, taking the example of determining whether to allow access to the monitor locally by using the local system resource utilization, the first access permission flag may be used to indicate whether to allow access to the monitor locally. For example, when the value of the first allowed access flag is 0, it indicates that the local access to the monitor is not allowed; when the value of the first access permission flag is 1, this indicates that the local access is permitted to the monitor. Of course, the value of the first access permission flag may also be expressed in other forms, and the specific expression form is not limited herein, and only needs to ensure that whether the access to the monitor is permitted can be distinguished by using the value of the first access permission flag.
Specifically, the step S22 includes the following steps:
s221, comparing the local system resource utilization with a corresponding system resource threshold.
The local is provided with thresholds corresponding to the system resource utilization one by one, for example, the CPU utilization corresponds to the threshold a, the memory utilization corresponds to the threshold B, and the network bandwidth utilization corresponds to the threshold C.
For example, a CPU idle rate of 80%, memory remaining 50%, and network bandwidth remaining 30% may be one configuration. When the CPU idle rate is 60%, the memory is not idle, and a new monitor cannot be accessed at this time.
The central station compares the obtained resource utilization rate of each system with the corresponding threshold value to calculate whether the current system is allowed to be accessed to the monitor or not, namely, the value of the first allowed access mark is updated. The principle is that any one of the three items of CPU, memory and network is smaller than the corresponding threshold value, namely, the access of a new monitor is considered not to be allowed any more.
S222, determining the value of the first allowed access mark by using the comparison result.
After the comparison, the central station updates the value of the first allowed access representation. As described above, when the value of the first allowed access flag is 0, it indicates that the local is not allowed to access the new monitor; when the value of the first access permission flag is 1, it indicates that access to the new monitor is permitted locally.
S223, forming a local running state based on the local system resource utilization and the value of the first allowed access flag.
The central station combines the value of the first access grant flag with the local system resource utilization to form a local operating state. The local operating state includes local identification information, an IP address, a port number, a system resource utilization, and a value of a first allowed access flag.
Wherein the local flag information indicates identification information of the central station to distinguish the respective central stations. For example, can be represented as DCS1, etc.
IP is an address group of the central station server, that is, the central station has a plurality of network cards, and then the IP address of each network card is included in the IP address.
The port number is a development port on the central station that waits for monitor access to be listened to, and for descriptive convenience, it is assumed that multiple central stations provide the same monitor protocol access, i.e., only one port.
S23, broadcasting the local running state to a network of the central monitoring system.
After the local operating state is formed in S223, the central station broadcasts the operating state in the form of a data packet (referred to as a system operating state data packet) to the network of the central monitoring system. For example, the system operational status data packet may be represented in the form of table 1:
Table 1 System operational status data packet
Figure GDA0002387149510000111
Wherein the checksum is used to validate the system operational status packet to determine if it is valid. The central station, after encapsulating the local operating state into the system operating state data packet described in table 1, broadcasts it into the network of the central monitoring system.
Referring to fig. 1, a system operation status packet broadcast on the central station 1 is received by a monitor on the central station 2, whether or not the central station 1 and the central station 2 are in the same network segment. That is, the system operation status data packet broadcast by the central station is received by all monitors in the central monitoring system.
S24, receiving the access request determined by the monitor based on all the received operation states.
After broadcasting the local system operation status data packet to the network, the central station may initiate a waiting monitor connection service to monitor whether there is a current access request of the monitor.
Please refer to S14 in the embodiment shown in fig. 2 for the rest details, which will not be described herein.
S25, according to the local running state, whether the monitor is allowed to be accessed to the local or not is confirmed.
After receiving the access request of the monitor, the central station performs confirmation again on the basis of the local operation state whether the monitor is allowed to access the local. Specifically, the step S25 includes the following steps:
S251, based on the local running state, judging whether the local allows the access of the monitor.
After receiving the access request of the monitor, the central station first uses the value of the local first permission access flag to judge whether the local permission access of the monitor is available. For example, when the value of the first allowed access flag is 0, it indicates that the local is not allowed to access the monitor; when the value of the first allowed access flag is 1, this indicates that the local allowed monitor is accessed.
Specifically, when the local access of the monitor is not allowed, S252 is performed; otherwise, the monitor is allowed to be accessed.
S252, waiting for manual confirmation to allow the monitor to access the local.
Because the system running state data packet broadcast to the network by the central station already comprises the local system resource utilization rate and the first access permission mark, the monitor screens which central station to send the access request to based on all running states.
If the monitor already knows that the local high load is still requesting, it will be explained that the local is the lowest load in the whole central monitoring system. Thus, it is necessary to wait for a manual confirmation of whether the monitor is allowed to access the local.
When the manual confirmation allows the monitor to be accessed to the local, allowing the monitor to be accessed; and when the manual confirmation allows the monitor to be accessed to the local, rejecting the monitor.
According to the networking method of the central monitoring system, the local system resource utilization rate is compared with the corresponding system resource threshold value to determine the value of the first access permission mark, the follow-up monitors can determine whether the central station is permitted to access the monitors or not by using the value of the first access permission mark, and networking efficiency of the central monitoring system is improved. The monitor determines the central station which is accessed based on all the received operation states, and even if the central station does not allow the access, the central station is the most suitable for the access in all the central stations, so that the secondary confirmation is performed manually to ensure the efficiency of the system networking.
As an optional implementation manner of this embodiment, S25 further includes:
transmitting corresponding response information to the monitor based on the confirmation result; the response information comprises an IP address of the local access of the monitor and a second permission access mark, and the value of the second permission access mark corresponds to the confirmation result.
Specifically, after confirming whether the monitor is accessible, the central station forms corresponding response information and sends the response information to the monitor. For example, the response information may be represented in the form of table 2:
TABLE 2 response information
IP address Second allowed access flag Checksum
The IP address is the local IP address of the monitor, and the value of the second permission access mark corresponds to the confirmation result. When the local monitor is not allowed to be accessed, the value of the second access permission mark is 0; the value of the second access permission flag is 1 when access to the monitor is locally permitted. Of course, the second allowed access flag may also be expressed in other forms, so long as it is guaranteed that it can distinguish between local confirmation results.
Optionally, after the central station does not allow the monitor to be connected and sends corresponding response information to the monitor, waiting for a certain time, if the monitor is not disconnected yet, the central station actively disconnects from the monitor. The purpose of waiting for a certain time is to ensure that the monitor receives the response information. The specific waiting time can be set correspondingly according to the actual situation, and can be 3S, 4S and the like.
In accordance with an embodiment of the present invention, a networking method embodiment of a central monitoring system is provided, it being noted that the steps shown in the flowchart of the figures may be performed in a computer system, such as a set of computer executable instructions, and that, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order other than that shown or described herein.
In this embodiment, a networking method of a central monitoring system is provided, which can be used for the above-mentioned monitor, and fig. 4 is a flowchart of the networking method of the central monitoring system according to an embodiment of the present invention, as shown in fig. 4, where the flowchart includes the following steps:
s31, receiving the operation state of each central station broadcasted in the network of the central monitoring system.
The running state of the central station is determined by the central station based on respective system resource utilization rates, wherein the system resource utilization rates comprise at least one of CPU utilization rate, memory utilization rate and network bandwidth utilization rate.
Each monitor in the central monitoring system initiates a service for listening to the UDP broadcast from the central station, which is used to listen to the operating status sent from the central station. After receiving the operation state of the central station, the monitor analyzes the operation state to obtain the system resource utilization rate of each central station.
For example, the monitor may store the operating states of the received central stations in the form of a data table, and the subsequent monitor may determine the target central station to be accessed by comparing the values in the data table.
The above S31 corresponds to S13 in the embodiment shown in fig. 2, please refer to S13 in the embodiment shown in fig. 2 in detail, and the detailed description is omitted herein.
S32, screening the central stations by using the received running states of the central stations, and determining the target central station.
The monitor screens the central stations from the received running states of the central stations to screen the central station with the smallest current load as the target central station.
S33, sending an access request to the target central station.
After determining the target central station, the monitor sends an access request to the target central station to request access to the target central station. This step corresponds to S14 of the embodiment shown in fig. 2, and reference may be made to S14 of the embodiment shown in fig. 2.
Before the monitor accesses the central station, the networking method of the central monitoring system provided by the embodiment determines that the appropriate central station sends an access request based on the received running states of all the central stations; therefore, the networking method is based on the real-time system resource utilization rate of the central station, and when the load of a certain central station is heavy, the monitor can not send an access request to the central station, so that the system downtime caused by overload operation of the central station can be avoided, and the stability of the central monitoring system can be ensured; when the load of a certain central station is smaller, the monitor can send an access request to the central station, so that the resource utilization rate of the central monitoring system is improved.
In this embodiment, a networking method of a central monitoring system is provided, which can be used for the above-mentioned monitor, and fig. 5 is a flowchart of the networking method of the central monitoring system according to an embodiment of the present invention, as shown in fig. 5, where the flowchart includes the following steps:
s41, receiving the operation state of each central station broadcasted in the network of the central monitoring system.
The running state of the central station is determined by the central station based on respective system resource utilization rates, wherein the system resource utilization rates comprise at least one of CPU utilization rate, memory utilization rate and network bandwidth utilization rate.
Corresponding to S23 of the embodiment shown in fig. 3, please combine S23 of the embodiment shown in fig. 3, the monitor receives the system operation status data packet for each central station, and after receiving the system operation status data packet for each central station, the monitor analyzes the system operation status data packet to obtain the operation status and checksum of each central station, and confirms whether the system operation status data packet is valid or not by using the checksum.
For example, a list of the operating states of the central station is maintained in the memory of the monitor, and the list contains content in a format similar to that shown in table 3 below:
TABLE 3 list of run states
Figure GDA0002387149510000151
After analyzing the operation state of each central station, the monitor fills the corresponding values into the corresponding positions in table 3, as shown in table 4:
table 4 list of running states
Figure GDA0002387149510000152
At the same time, the monitor updates the table 4 at regular intervals, so that the table 4 can represent the current operation state of each central station. The update time interval corresponds to a transmission time interval of the central station, for example, the central station transmits the system operation status data packet every 3S, and the monitor updates the table 4 every 3S.
S42, screening the central stations by using the received running states of the central stations, and determining the target central station.
The monitor finds itself not connected to the central station, and immediately uses the received operation states of the central stations to screen the central station, that is, uses the values in table 3 to perform comparison operation, and screens the target central station. The screening principle is to look at the first allowed access mark, select more idle CPU, compare memory and reference network.
S421, judging whether a first permission access mark exists in the running state of each central station.
When the first access permission flag is present in the operation state of the central station, S422 is performed; otherwise, S423 is performed.
S422, the target central station is determined based on the system resource utilization in the operation state of each central station.
Specifically, the process of determining the target central station may be expressed as follows:
(1) The value of the first allowed access flag in the running state table is checked first, and if the value of the first allowed access flag is 0, a central station with the value of the first allowed access flag being 1 is selected for comparison. Taking table 4 as an example, where the value of the first allowed access flag corresponding to the central station 2 is 0, the selection of the target central station is performed from the central station 1 and the central station 3.
(2) Since the central station 1 has a larger idle rate than the central station 2, the central station 1 is selected as the target central station.
(3) As shown in table 5, when the idle rate is the same, the memory is used for comparison:
TABLE 5 running State Table
Figure GDA0002387149510000161
As shown in table 5, the idle rates of the central station 1 and the central station 3 are the same, and the central station 3 is selected as the target central station because the memory idle rate of the central station 3 is large.
And sequentially screening the CPU utilization rate, the memory utilization rate and the network bandwidth utilization rate in the system resource utilization rate of each central station to determine the target central station.
S423, sequentially screening the CPU utilization rate, the memory utilization rate and the network bandwidth utilization rate in the system resource utilization rate of each central station to determine the target central station.
In case the value of all first allowed access flags is 0, it is still necessary to select one central station with the smallest load. As shown in table 6, when the values of the first access permission flags are all 0, the CPU idle rate, the memory utilization rate, and the network bandwidth idle rate are sequentially used for comparison.
TABLE 6 running State Table
Figure GDA0002387149510000171
As shown in table 6, if the CPU idle rates of the 3 central stations are the same and the memory idle rate of the central station 2 is large, the central station 2 is selected as the target central station.
S43, sending an access request to the target central station.
The monitor, after determining the target central station, sends an access request thereto. This step corresponds to S24 of the embodiment shown in fig. 3.
According to the networking method of the central monitoring system, the monitors judge whether the central stations are allowed to be accessed to the monitors or not by using the first permission access marks in the running states of the central stations, and when the first permission access marks are not present in the running states of all the central stations, the system resource utilization rate of each central station is used for screening again so as to improve the networking efficiency of the system.
As an alternative implementation manner of this embodiment, the step S43 further includes:
(1) Waiting for receiving the response information sent by the target central station, and displaying the accessed target central station on a local interface.
The response information comprises an IP address of the local access target central station and a second access permission mark, and the value of the second access permission mark corresponds to the result of whether access is permitted or not.
The monitor waits to receive the response message from the target central station after sending the access request to the target central station. The response information sent by the target central station is shown in table 2, and includes an IP address, a second allowed access flag, and a checksum.
The monitor displays the accessing target central station on its interface during the waiting process, optionally, the monitor sends a heartbeat packet to the target central station during the waiting process to maintain the connection with the target central station.
(2) And prompting whether the target central station needs to wait for manual confirmation or not on a local interface based on the first access permission mark corresponding to the target central station.
Meanwhile, if the value of the first permission access flag corresponding to the target central station screened by the monitor is 0, the interface of the monitor is also used for prompting whether the target central station needs to wait for manual confirmation.
After receiving the response information of the target central station, the monitor analyzes the response information to obtain the value of the second permission access flag. When the value of the second access permission flag is 1, indicating that the target central station permits access to the monitor, then the monitor maintains a connection with the target central station and communicates with the target central station using the connection; when the value of the second access permission flag is 0, which indicates that the target central station does not permit the participation of the monitor, the monitor needs to immediately disconnect from the target central station and resume the collection of connectable central stations.
