Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention is further illustrated.
As shown in figure 1, in the distributed monitor system of the present invention in the method and apparatus embodiment of Backup Data, monitoring
The data backup of instrument and server comprises the following steps：
Step S11 determines that the connection between patient monitor and server disconnects：In the present embodiment, distributed monitor system
Including multiple servers and multiple patient monitors, these servers and patient monitor are connected on same network, wherein, each monitoring
Instrument passes through network connection with one in the multiple server（In the presence of or establish interface channel）And obtained monitoring
Data are uploaded in connected server；The connection inventory of patient monitor is stored with server, specifies the server can be with
The patient monitor mark of connection；The patient monitor mark can be title, network address, identity code or the position of setting of patient monitor
Put etc. parameter.In the present embodiment, when being electrically connected to network on patient monitor（I.e. patient monitor initial connection server when）, it is
The connection server inventory being stored therein by transferring, according to the order of server in the inventory, connection request is sent one by one,
If successful connection, attempt to connect following server.I.e. obtain patient monitor storage, be provided with the order of connection in advance
Server list；According to the order of server in the server list, each server pair in the list is obtained successively
The address answered, connection request is sent to the server one by one；As server allows to connect, then establish and connect with the server, and
Upload monitoring data；Otherwise, repeated the above steps using different server address, connected until establishing always（Be probably and
Any one server in above-mentioned inventory establishes connection）.In the inventory, including the title of server, address and its it is used for
The port of connection；Can sends connection request to server after patient monitor obtains these parameters, when server allows connection,
The two establishes interface channel, and the monitoring data that patient monitor obtains will be formed packet and upload to the server and store；Work as clothes
When business device often receives the packet that a patient monitor is sent, one determination signal of the patient monitor can be all returned, represents server
Receive the packet.But for various reasons, the connection of the server and patient monitor may be interrupted, particularly in server
In the case of failure.In general, the performance of this failure is that server is not responded to the packet that patient monitor uploads,
I.e. server will not send the determination signal for receiving packet.When there is above-mentioned interruption situation, this step is performed, it is determined that monitoring
Instrument and the interface channel of its server being originally connected are already off, and patient monitor does not receive the determination signal that server is beamed back.
Can also it not received accordingly in scheduled duration by central station further, it is also possible to be detected and whether connected according to network signal
Packet judges whether that central station and patient monitor disconnect.
Step S12 obtains the server list of storage, sends connection request one by one：In this step, as in previous step
The patient monitor of description be initially connected to it is operated during network as, obtain be previously stored in patient monitor can connection server
Server inventory, and send each server in connection request to the inventory one by one according to the inventory；Please when sending connection
When asking to a server, the server may allow to connect or not allow to connect or not respond, and allow the situation of connection
Under, patient monitor attempts to connect next server, performs next step；When server reply does not allow to connect or does not have back
When multiple（Within the time of a setting）, patient monitor is to the server transmission connection request on next inventory, repetition the above；
If the server on whole inventories had all tried, but all then repeated this step without in connection.
The server for allowing connection of the first reply of step S13 connections：In this step, due to the connection request of transmission
Being serviced device receives and allows to connect, and in this step, will connect the server（Even if there are multiple servers to connect, but
Being replied at first due to the server allows to connect, and patient monitor will not attempt to connect other servers）With the patient monitor, at the two
Between establish interface channel.After having performed this step, next step is performed.
Step S14 uploads data：In this step, the service by being originally stored in the connection inventory in patient monitor
The mode of device address, the patient monitor go offline and then secondary connection on another be connected to server on network.Therefore,
The monitoring data currently obtained is uploaded on the server and stored.In some cases, can also be by the patient monitor most
Current monitoring data is arrived after once going offline afterwards（Or it is historical data）The server is uploaded to, to ensure the complete of monitoring data
Whole property.
Generally, when the server in the server list stored in patient monitor can connect, above-mentioned steps are enough
The patient monitor to go offline is connected in secondary and online server and carries out data backup.But answering due to network environment
Polygamy, in the present embodiment, it is also possible to another situation occur, i.e., the server in the patient monitor server list is due to kind
Kind reason can not all connect.Now, after the S12 setting times that repeat the above steps, the patient monitor still can not connect, and show this
Server in server list is likely to occur problem, therefore, in the present embodiment, can perform following steps（Refer to figure
2）：
Whether step S21 receives broadcast message, performs next step in this way；Otherwise, it is initial to perform above-mentioned patient monitor
Connection Step, until establishing connection with any one server in the server inventory in above-mentioned patient monitor, that is, jump to step
Rapid S25.
Whether this patient monitor mark is carried in step S22 broadcast messages：In this step, the broadcast received is judged
Whether the mark of this patient monitor is carried in information.Specifically, exactly the broadcast message received is unpacked, taking-up is wherein set
What carrying was put in positioning can be with the server（Send the server of the broadcast message）The mark of the patient monitor of connection, and with
The mark of this patient monitor is compared, if identical, is judged as carrying the mark of this patient monitor, the clothes in the broadcast message
Business device can connect with this patient monitor, perform next step；If it is not the same, then it is judged as that the server can not be with this patient monitor
Connection, jumps to step S25.
Step S23 obtains the server address in the broadcast message, sends connection request：In this step, broadcast is taken out
Server address and connectivity port in message send connection request as destination address to the server.In the present embodiment,
Above-mentioned server address and connectivity port are also in the specified location in the broadcast message, as long as broadcast message is unpacked simultaneously
Read the data of specified location, you can obtain above-mentioned server address and connectivity port.It is noted that in the present embodiment
In, patient monitor is likely to be received multiple broadcast messages from different server, in this case, according to the priority received
Order carries out above-mentioned judgement to multiple broadcast messages, only when all broadcast messages are all without the mark of this patient monitor,
Step S24 can be performed；When wherein there is the mark that this patient monitor is carried in multiple broadcast messages, by according to the order received
Next step is performed one by one, i.e., according to reception order, takes out the server address in broadcast message respectively, and send connection one by one
Request, until connection is established.
Whether step S24 servers allow to connect：After patient monitor sends connection request, begin to listen on network
Information, is waited and what the reception server was sent allows the echo message of connection, if receive that the server sends allows to connect
The information connect, then it is judged as that server allows to connect, performs next step；If above-mentioned clothes are not received by setting time
The information for allowing connection that business device is sent, then be judged as that server does not allow to connect, and performs step S25.Similarly, in this implementation
In the case of this patient monitor mark being present in the above-mentioned broadcast message that multiple servers be present and send in example, when judging that one services
, it is necessary to which another server sends connection request when device does not allow to connect, and wait its response；Only carrying is sent all
The server of the broadcast message of patient monitor mark is all judged as in the case of not allowing connection, can just jump to step S17
Perform.
Step S25 when patient monitor initial access network by the way of connection server：In this step, according to above-mentioned
The mode that patient monitor initially connects, connection request is sent to the server connected on inventory stored in the patient monitor one by one, and
Its response is waited, until connection is established.In fact, in the present embodiment, this step and above-mentioned steps S12 are roughly the same.
After having performed this step, step S26 is performed.
The server and the patient monitor that step S26 connections are replied：In this step, due to the connection request bedding and clothing of transmission
Business device receives and allows to connect, and in this step, will connect the server and the patient monitor, and it is logical to establish connection between
Road.In fact, in the present embodiment, this step and above-mentioned steps S13 are roughly the same.After having performed this step, it will redirect
Go to perform to step S14.
Fig. 3 shows that patient monitor is when obtaining a server address carried by broadcast message in the present embodiment, with this
Server establishes the specific steps of connection.In figure 3, the step of patient monitor establishes connection with server is as follows：
Step S31 obtains the server address in broadcast message：In this step, the broadcast that patient monitor is received disappears
Breath unpacks, and the specified location of the information after unpacking obtains sending the address and its connection end of the server of the broadcast message
Mouthful.
Step S32 sends connection request：In this step, by the server address obtained in above-mentioned steps and connection end
Mouth is used as destination address, is formed and sends connection request to above-mentioned server.
Step S33 takes out the patient monitor mark in connection request, is searched in inventory：In step, in server reception
The connection request that patient monitor is sent is stated, and takes out the patient monitor mark carried in the connection request, the patient monitor is the company of sending
Connect the patient monitor of request；Afterwards, the patient monitor mark is searched in the patient monitor inventory of its own storage, if the patient monitor mark
Know in the patient monitor inventory of server, identify the server and be set and can be connected with the patient monitor, then the server is sent out
Go out echo message, expression allows to connect, and then performs step S35；If the patient monitor mark in above-mentioned inventory, does not service
Device does not send the response for allowing connection.
Step S34 is opened and is intercepted port, the echo message of the reception server：In this step, when patient monitor transmission is above-mentioned
After connection request, that opens its mixed-media network modules mixed-media intercepts port, to receive the echo message of server.It is noted that
Because step S34 and S33 occur on different physical supports, so, from the time, actually step S34 is hair
Life is preceding, and the arrangement mode of the two steps is not offered as step S34 mono- and is scheduled on step just for the sake of the convenience of narration herein
Occur before rapid S33.
Step S35 establishes connection：In this step, patient monitor and server establish connection, in order to which patient monitor can incite somebody to action
The monitoring data that historical data after going offline currently obtains is transferred to above-mentioned server and carries out data backup.
Step S36 is managed to patient monitor：In this step, due to having been built between patient monitor and server
Connection is stood, it is possible to which certain management is carried out to above-mentioned patient monitor by server.Such as, it is desirable to patient monitor uploads history
Data etc..
Fig. 4 shows in the present embodiment how by current monitoring data bags to obtain the flow of historical data.In Fig. 4, should
Flow includes：
Step S41 is by obtaining its package number in current data packet：As described above, when patient monitor and a new clothes
It is engaged in after device foundation connection, patient monitor starts currently available monitoring data uploading to the server.In the present embodiment, each
The packet that patient monitor is sent is provided with package number, and it is demonstrated by the order of packet.In this step, there is above-mentioned prison
Shield instrument establishes after connection first packet transmitted with new server and obtains the numbering of the packet.
The package number is subtracted one by step S42, it is required that package number, and the packet of the requirement is compiled
Number it is sent to patient monitor：The numbering of packet obtained above is subtracted one, a packet before obtaining current data packet is compiled
Number, that is, the package number required, the packet is historical data, i.e., in patient monitor go offline after and the new server of connection it
Preceding packet.The packet is not transferred to server holding due to going offline.
Step S43 obtains the model of historical data bag by the package number of go offline time and the above-mentioned requirements of last time
Enclose：In this step, the time point to be gone offline by patient monitor and the package number of above-mentioned requirements, obtain the patient monitor and going offline it
Afterwards, the physiological parameter data bag gathered before the connection with server is re-established.In the present embodiment, because starting time is
It is known.The time interval for sending packet is known, meanwhile, the numbering of current data packet（Or the packet of above-mentioned requirements
Numbering）It is known, so the data for being not difficult to obtain therebetween included by how many packet are not delivered to server.
Step S44 judges whether historical data bag is sent completely, and in this way, performs lower step S46, otherwise, performs step
S45：In this step, due to obtaining needing to send multiple packets in above-mentioned steps, so judging above-mentioned go through in this step
Whether history packet is sent, and in this way, performs step S46；Otherwise step S45 is performed.
Step S45 is searched and is concurrently sent packet corresponding to the package number of above-mentioned requirements：In this step, due to still
Need to send historical data and the package number of known requirement, so searching the packet of the numbering on patient monitor, find
After be sent to server.It is noted that the packet is not current data.But historical data, so servicing
It is labelled on device, it is historical data to show it.After performing this step, using the package number of above-mentioned requirements as currently
Numbering, jumps to step S42；
Step S46 exits historical data transmission, only sends current data packet：In this step, it is all due to having sent
Historical data（Gone offline by patient monitor last time to all packets current data packet）, gone through so not retransmiting
History packet, and current monitoring data is only sent to above-mentioned server.
In the present embodiment, above-mentioned distributed monitor system needs the central station of 2 and more than 2（Server）, often
Individual central station can both access patient monitor in real time, other can also be waited to allow the patient monitor of access to access at any time, so as to realize
There is the target of multiple backup central stations.For example, in the case where there is two central stations, central station 1 is intercepted specific using Socket
Port waits patient monitor connection.The central station address that patient monitor configures according to itself is connected to central station 1.How many patient monitor
Central station 1 is connected to, there is the TCP of respective numbers（Transmission Control Protocol）It is connected to central station 1
Between patient monitor；Central station 2 intercepts particular port using Socket and waits patient monitor connection.Patient monitor configures according to itself
Central station address is connected to central station 2.How many patient monitor is connected to central station 2, and the TCP that there is respective numbers is connected to
Between central station 2 and patient monitor.In the present embodiment, above-mentioned patient monitor with central station is connected by Ethernet under normal conditions
's；But in some cases, patient monitor may also be non-Ethernet interface, at this time, it may be necessary to the patient monitor and central station it
Between connect a non-Ethernet AM access module so that should be linked into without patient monitor of Ethernet interface by virtual mode
On above-mentioned central station.After non-Ethernet AM access module starts, according to the central station address of its configuration, non-Ethernet will be linked into and connect
Enter the patient monitor of module virtually and be connected to central station, can be central station 1 or central station 2.Deposited under non-Ethernet AM access module
In how many individual patient monitors, then the TCP that respective numbers are there is between non-Ethernet AM access module and central station is connected.
The example of one reality is, the TCP that central station 1 and central station 2 first start socket intercepts access service, waits
Come from the patient monitor connection of network；Then UDP is started（User Datagram Protocol）Address broadcast service, it is generally every
The broadcast once available link address of itself, port and the additional monitoring for allowing to be connected to central station by broadcast address in 3 seconds
Instrument is numbered.The content format of broadcast message is：
| Central station IP address | Central station port numbers | Allow the patient monitor numbering of access |
The patient monitor numbering of access is wherein allowed to be pre-configured with central station.
According to the central station IP address information of configuration after patient monitor startup, central station is attempted to connect to socket TCP
1.Start address broadcast simultaneously and intercept, for etc. the address broadcast message to be received from central station；Central station 1 receives connection
Searched with patient monitor numbering in the accessible patient monitor list of this central station, if allowing access just the connection IP of patient monitor
Location information and patient monitor numbering are added to the start-up operation such as managing listings, device data analysis service, and patient monitor is on central station
Line.If not allowing, patient monitor is disconnected.
If patient monitor successful connection is put into normal work stage.If patient monitor is disconnected, in the present embodiment.It can adopt
With a kind of access for realizing patient monitor in following 3 kinds of modes：
Static backup：Patient monitor can use the address of the central station address list of default configuration, attempt one by one and center
Stand connection, until can be connected to work(.Here address is pre-configured with patient monitor, preserves these ground for a long time by patient monitor
Location, to complete to automatically switch using these addresses when breaking down.This mode is the most frequently used, is easiest to realize
Backup mode.
Dynamic backup：Patient monitor is attempted to connect using the central station broadcast address received.Patient monitor is first from address
The numbering of this patient monitor is searched whether in message, if in the presence of the central station address and port that connect in this message, it is no
Then just abandon using the address in the message.When multiple central stations broadcast address message simultaneously be present, using first first
Principle, message is attempted one by one.If message addresses are all attempted to be all connected with unsuccessful, patient monitor automatically attempts to connect default configuration
Central station address, until can be with normal work.
Quiet dynamic combination：Patient monitor first attempts the central station of connection backup, if unsuccessful, prison using first way above
Shield instrument continues to use the broadcast address in the second way to attempt to be connected with central station, until success.In superincumbent description, adopt
It is exactly this connected mode.
When central station receives patient monitor connection request, first lookup patient monitor is numbered from the list of devices for allowing access.
If allowing the numbering of access, access the patient monitor and do corresponding management work, otherwise disconnect.Accessed in the patient monitor
Management work in, judged whether patient monitor is in the patient monitor list from backup before this.If the patient monitor of backup, center
Stand and first access patient monitor.So far, patient monitor has accessed central station, and in the present embodiment, backing up in realtime for data can adopt
Take one kind in following method：
Only focus on current latest data：Patient monitor only sends current real time data, and central station is exposed directly to user, right
