Embodiment
The invention discloses a kind of breaker point continuous transmission method of data, as shown in Figure 1, the networking schematic diagram between patient monitor and central monitoring system, connected mode is that the wired of Ethernet can or wireless.
Describe by 2 patient monitors the pattern be connected with the network of central monitoring system in Fig. 1, patient monitor 1 and patient monitor 2 must be the patient monitors achieving breakpoint transmission function.
In order to realize breakpoint transmission function, each patient monitor has unique monitoring numbering, each monitoring data bag not only has the data serial number (carrying out layout) of time sequencing generation per second that is unique, that produce according to data, and has attached unique monitoring numbering above.
After patient monitor is connected to the real time data receiving port of central monitoring system, when central monitoring system judges to be the same monitoring numbering of again reaching the standard grade after broken string, the data serial number of broken string to the packet be not transmitted again reaching the standard grade is calculated by central monitoring system, then the data serial number needing again to transmit is organized into breakpoint transmission request data package and is sent to patient monitor, patient monitor according to request data package by the data packet transmission of reference numeral to the breakpoint transmission port of central monitoring system, finally from real-time monitoring data and breakpoint transmission data, data stored by central monitoring system or draw.As shown in Figure 2, central monitoring system performs following steps:
Step S1, receiving step, central monitoring system receives the monitoring data bag that patient monitor sends, and then performs step S2, and described monitoring data bag comprises data serial number and monitoring numbering;
Step S2, identification determining step, judge whether consistent the monitoring numbering in the monitoring data bag received numbers with the monitoring in the monitoring data bag broken, if inconsistent, so perform real-time data memory and drafting, otherwise carry out real-time data memory and drafting and perform step S3, create breakpoint transmission request data package step.
In described real-time data memory, in the data space that the drafting service that the monitoring data bag received is stored into central monitoring system can be had access to by the real time data processing thread of central monitoring system.
In step s 2, central monitoring system is verified monitoring data bag the good according to the rules packet length of the monitoring data bag received and check digit algorithm, and judge that the new monitoring numbering connected is numbered with the monitoring in the monitoring data bag broken (as, monitoring numbering before last broken string) whether consistent, it is new monitoring that inconsistent words then can identify, if newly guard, so the monitoring data bag received is stored in the service of the drafting data space that can have access to; If not newly guard, be namely the monitoring at monitoring process interrupt line, the serial number of the first bag data after again reaching the standard grade is defined as A here, monitoring number definition is PID, and flow processing just walks the "Yes" branch in Fig. 2.
Step S3, establishment breakpoint transmission request data package step, central monitoring system starts the thread that performs breakpoint transmission task, this thread creates breakpoint transmission request data package according to last monitoring data bag before breaking and first monitoring data bag after again reaching the standard grade, and then performs step S4, forwarding step.
In step s3, cross-thread is independent of each other owing to can work alone, the monitoring that the thread of breakpoint transmission task is current according to central monitoring system is numbered, find the data serial number of last monitoring data bag before breaking, here defining this serial number found is B, according to the B at PID and A in flow process above and this place, breakpoint transmission request data package can be organized into following 2 kinds of forms, the all data serial numbers (comprising B and A) be about between last packet before breaking to the first bag data after again reaching the standard grade are written in breakpoint transmission request data package in order.
The first is according to A and B, calculates concrete breakpoint serial number and is organized into packet again, and comprise the information such as length and data check position, bed label of packet in its middle wrapping head, bag tail refers to the end-of-packet mark of regulation.As follows:
The second only adopts A and B to be organized into packet, namely calculates concrete breakpoint serial number from B to A by central monitoring system according to A and B in packet.
| Packet header | PID | A | B | Bag tail |
When being judged as not being new monitoring, central monitoring system starts to calculate, organize breakpoint transmission request, real-time process and monitoring are carried out to the data after again reaching the standard grade simultaneously, breakpoint data can be processed while draw the data of new monitoring, can the transmission of real-time monitoring data do not affected and realize data integrity reparation under drawing.
Step S4, forwarding step, be sent to patient monitor by the breakpoint transmission request data package of generation.
Central monitoring system also comprises the steps:
Breakpoint transmission receives data packets step, central monitoring system receives the breakpoint transmission packet of patient monitor transmission and stores;
Breakpoint repairs step, in the intermittent phase that real time data is drawn, carries out breakpoint reparation.
The intermittent phase that real time data is drawn comprises any one situation following: when waveform drawing interface is refreshed automatically, manually the refreshing of dragging waveform drawing interface, user check monitoring history and retrospective analysis care situations.
As shown in Figure 3, in the breaker point continuous transmission method of these data, patient monitor performs following steps:
Step Q1, intercept step, intercept the breakpoint transmission request data package that central monitoring system sends, then perform organising step;
Step Q2, organising step, according to breakpoint transmission request data package, patient monitor is inquired about corresponding data, organizes data into breakpoint transmission packet;
Step Q3, patient monitor forwarding step, by breakpoint transmission Packet Generation to central monitoring system.
In step Q1, patient monitor can listening port be breakpoint transmission work upon actuation, and service here can adopt TCP or UDP to carry out communication, as long as central monitoring system adopts corresponding mode breakpoint transmission request data package to be sended over.
In step Q2, organize data into breakpoint transmission data and be surrounded by 2 kinds of modes, the first to need the breakpoint transmission packet sent to send to central monitoring system one by one, and similar form is as follows:
The second to need the breakpoint transmission packet data sent to mix, and once sending how many data volumes can determine according to maximum transmission length.Be organized into following form:
The first organizational form is the same with the packet sent in real time, and codes implement is easy; The second way sends can reduce transmission times, also can reduce the data volume of transmission.
Data volume in breakpoint transmission packet refers to the monitoring data produced when real-time monitoring, these data are just used on central monitoring system, be shown as waveform, curve or care situations binary data, as long as have broken string on waveform or curve, the data in these data volumes are lacked exactly.
In step Q3, patient monitor by breakpoint transmission Packet Generation to the breakpoint transmission serve port of central monitoring system (this port and real time data receiving port are not two independent hardware interfaces, but by two data-interfaces of software simulating).Here communication also can adopt TCP or UDP to carry out communication, and this is determined by central monitoring system, as long as adopt corresponding mode request msg to be sent.
As shown in Figure 4, as one embodiment of the present of invention, effective data authentication step is also comprised in step Q1 and step Q2, in valid data verification step, judge whether the breakpoint transmission request data package received has completeness and efficiency, if so, so perform step Q2, otherwise the breakpoint transmission request data package received directly is abandoned, then continues to perform step Q1.
Whether central monitoring system can make regular check on data has breakpoint, namely judges whether data serial number exists discontinuous situation, if any breakpoint, automatically breakpoint transmission request data package can be created, repair, do the process can avoided a large amount of abnormal conditions like this, raise the efficiency.
As shown in Figure 5, in described breakpoint transmission receives data packets step, specifically comprise the steps:
Step W1, receives breakpoint transmission packet;
Breakpoint transmission data are stored in memory by step W2.
Memory comprises database and breakpoint transmission data queue, that is, in step W2, breakpoint transmission data can be stored and be stored in breakpoint transmission data queue in a database or by breakpoint transmission data.
Benefit breakpoint transmission data stored in a database to store more data, is that storage is fast, reading is fast, is beneficial to refreshing by the breakpoint transmission data advantage be stored in breakpoint transmission data queue.
Wherein, in step W2, breakpoint transmission packet storage mode has two kinds, and the first is breakpoint location place breakpoint transmission data being stored into the monitoring data bag in data space, and the second is that breakpoint transmission data are stored in data space; So when the first storage mode, generate continuous print waveform in the intermittent phase that real time data is drawn (when such as checking monitoring history or retrospective analysis care situations) meeting according to the partial data after supplementing and show complete waveform, like this, user can obtain the complete data not having breakpoint when checking monitoring history or retrospective analysis care situations, improves Consumer's Experience; So when the second storage mode, read data in the intermittent phase (such as when review history) that real time data is drawn according to the order of data serial number and show complete waveform.
Wherein, in step W2, the third mode that breakpoint transmission packet stores is: need form required for drawing waveforms by data transaction, then being placed on one draws in the memory space of serving and can access, namely breakpoint transmission data queue is cached to, waiting system reads data, and the benefit done like this does not affect current monitoring data drawing waveforms, and the Wave data after broken string can not cause interference to real-time monitoring data.
As shown in Figure 6, as one embodiment of the present of invention, between step W1 and step W2, also comprise effective data authentication step, in valid data verification step, judge whether the breakpoint transmission packet received has validity, if, so perform step W2, otherwise perform step W1.If the length of breakpoint transmission packet not, check digit can't pass verification or bag tail is incorrect etc. all can not be thought effective, like this, avoid the process to invalid data, prevent system fault, increase work efficiency.
As shown in Figure 5, repair in step at breakpoint, specifically comprise the steps:
Step V1, judges whether the intermittent phase being in real time data drafting, if so, so performs the breakpoint location that the breakpoint transmission packet stored is added to monitoring data bag by step V2., otherwise proceeds real time data drafting;
In real time data drawing process, judge that whether the data serial number of monitoring data bag is continuous, if continuously, so waveform is drawn continuously, otherwise in drawing waveforms process, reserves the ignore corresponding with the data serial number lacked at breakpoint location place or draw continuously at breakpoint location place in drawing waveforms process.
Be specially, in real time data drawing process, if when being judged as that the data serial number of monitoring data bag is discontinuous, comprising two kinds of real time datas and draw mode.
After data are taken in drafting service, during waveform in drafting first packet, need the dummy section vacating certain distance between the last point data of previous monitoring, and the icon representation drawing a newly monitoring herein is newly guarded.New monitoring is done calculating to data serial number and is judged whether continuously in monitoring process, if the serial number calculated is discontinuous, the first real time data draws mode: in the drafting of waveform, just vacate corresponding position, lacks several serial number just empty several point.The second real time data draws mode: in the drafting of waveform, need not vacate the point lacked, waveform is drawn continuously at breakpoint place.
Clinically, monitoring data comprises two classes, the first kind is the initial data (comprising through preliminary treatment as the initial data after filtering) that patient monitor gathers, Equations of The Second Kind is by the process of primary sources and the various physiological parameter standard values that calculate, as pulse frequency, respiratory rate, blood oxygen saturation etc.
Generally speaking, in waveform drawing and display mode, primary sources adopt the mode of cover type to show, the region of a regular length is plotted in by monitoring data, when the waveform current location of drawing reaches can drawing area length, need from starting position, region covering and drawing, the data be capped directly can abandon and not preserve; Secondary sources adopt the mode of extension, and namely monitoring data is plotted in a region that can extend continuously.This is because the data volume of the initial data gathered is larger, preservation meaning is smaller, is applicable to the mode of cover type; And by primary sources process and the physiological parameter data data volume that calculates smaller, preservation meaning is larger, is applicable to the mode of extension.
Further, in step W2, preferably, send to the packet identification information of central monitoring system according to custodial care facility, if primary sources, then store in a database; If secondary sources, be then stored in breakpoint transmission data queue.Reason is that the data volume of primary sources is larger, carry out memory capacity in a database and can reach requirement, and the data volume of secondary sources is less, can store in breakpoint transmission data queue, and access data is fast in breakpoint transmission data queue, be convenient to carry out supplementing to data in the short and small time slot refreshed repair.
Refreshing comprises waveform drawing interface and automatically refreshes or manually drag the refreshing of waveform drawing interface.
Waveform drawing interface is refreshed automatically also can be called as the call that refreshing " paper feed " here that waveform drawing interface automatic carriage causes is a kind of custom in this area, paper feed operation when " paper feed " does not refer to that printer prints, and refer to the movement of window interface, such as drag scroll bar and interface is moved.
In the waveform display mode of extension, particularly, waveform drawing draws according to parameter value in the X and Y coordinates of paper, if X-coordinate is first plotted to 40, Y from 0 and is plotted to 30 from 0, so just obtains the paper that 40 is multiplied by 30 here.Often carry out a parameter, just need to draw a point on waveform, counter so in X-coordinate will add 1, when counter is added to 40 time, X is just needed to extend to 80 (paper feed step-length adjustable) from 40, the waveform of above 0 to 40 can move to the opposite direction of the paper newly extended out, similar computer window interface, below there will be scroll bar, so now just obtain the paper that 80 is multiplied by 30, and need 0 to have refreshed rear all data points to current paper feed and redraw above, and just the Plotting data of breakpoint transmission is employed in redrawing specifically.
Artificial dragging waveform drawing interface refresh be medical personnel look back above care situations time, drag the refreshing that scroll bar or interface etc. cause.
When waveform drawing refreshes, utilize the time slot that paper feed refreshes, just can complete breakpoint data restore.
In the present invention, for primary sources, selecting to repair breakpoint data when refreshing, in the time slot that Wave data can utilize paper feed to refresh, repairing breakpoint, and the partial data after repairing is preserved, check after being convenient to.For secondary sources, select to repair breakpoint data when checking monitoring history or retrospective analysis care situations, thus view complete waveform.
As shown in Figure 6, as one embodiment of the present of invention, also comprise between step V1 and step V2 and call breakpoint transmission packet step and valid data verification step, in valid data verification step, judge whether the breakpoint transmission packet fetched has data, if so, so perform step V2, otherwise perform real time data plot step.Like this, avoid the process to invalid data, prevent system fault, increase work efficiency.
Central monitoring system is in real time data drawing process, whether the data serial number of periodic detection drawing waveforms is continuous, if discontinuous, then carries out real-time data memory and drafting and perform creating breakpoint transmission request data package step, otherwise, carry out real time data and draw storage and draw.
