in one embodiment, described control module 14 also is configured to identify according to pre-defined rule the priority level of each data, for example distribute the priority level of each data according to Data Source or data class, or distribute the priority level of each data according to data importance or real-time property, then control module 14 is added other data of same priority to the transmit queue corresponding with this priority level, control module 14 sends to communication apparatus 20 according to the transmission policy corresponding with each transmit queue with the packing of the data in transmit queue, communication apparatus 20 will be given long-range receiving terminal (for example central control system in institute 200) by wired or wireless Internet Transmission about patient's the transmission of data.
In a kind of instantiation, as shown in Figure 2, control module 14 comprises queue assignment unit 141 and transmission unit 142, queue assignment unit 141 is used for obtaining data from functional module 11 and/or memory module 12, identify the priority level of each data according to the real-time of Data Source, data type, data importance or data, and add other data of same priority to the transmit queue corresponding with this priority level 143.Transmission unit 142 is used for inquiring about pre-stored at the transmission policy of memory module 12 and the corresponding table 121 of priority level, according to the transmission policy corresponding with each transmit queue, the data in transmit queue is sent to communication apparatus 20.
Based on the structure of this specific embodiment, when carrying out transfer of data, its flow process comprises the following steps as shown in Figure 3:
Step S11, the data that the control module Real-time Obtaining of Medical Devices need to be uploaded, the data that the needs that obtain are transmitted are divided into different priority levels according to pre-defined rule.priority level has a plurality of, for the pre hospital care system, the transmission of data can be divided into 4 grades, it is the important real-time Transmission that needs, the important real-time Transmission that do not need, inessential real-time Transmission and the inessential data that do not need real-time Transmission of needing, for example the important data of real-time Transmission that need comprise electrocardio real-time waveform data, breathe at least one in real-time waveform data gps data, the important data of real-time Transmission that do not need comprise the ecg analysis report, case history, at least one in audio, video data and treatment data, the inessential data of real-time Transmission that need comprise blood oxygen Wave data, at least one in blood pressure data and temperature data, the inessential data of real-time Transmission that do not need comprise machine parameter etc.The sequence of its priority level reduces successively, does not need the data of real-time Transmission＞inessential data that do not need real-time Transmission for: important data that need real-time Transmission＞important do not need the data of real-time Transmission＞inessential.
Step S12 adds other data packing of same priority to the transmit queue corresponding with this priority level; Be that other data arrangement of same priority is a formation, this formation also has and the equal priority level of data wherein.
Step S13 when needs send data, carries out reading and sending to communication apparatus to the data in transmit queue according to each self-corresponding transmission policy.Transmission policy can be set to different strategies according to actual conditions, or is suitable for multiple transmission policy simultaneously.In the present embodiment, for different priority level transmit queues distributes different Transmission Time Intervals, be that the Transmission Time Interval Priority-based is not set, the Transmission Time Interval of the formation that priority level is high is less than the Transmission Time Interval of the low formation of priority level, for example, be pre-created the corresponding table of Transmission Time Interval and priority level, priority level is higher, Transmission Time Interval is less, priority level is the highest is set as real-time Transmission, the Transmission Time Interval of each priority level can be fixed, and can be also adjustable.In the correspondence table, no matter the Transmission Time Interval of each priority level is fixing or adjustable, and clock keeps the Transmission Time Interval of the high formation of priority level less than the Transmission Time Interval of the low formation of priority level.Control module obtains the Transmission Time Interval of individual queue by reading corresponding table, and fetches data from individual queue according to the time interval, and sends the data to communication apparatus.
Step S14, communication apparatus sends to receiving terminal with the packet that receives by wired or wireless network.
in improved embodiment, described communication apparatus 20 receives the response message that is returned by receiving terminal, and response message is returned to control module 14, in a kind of instantiation, as shown in Figure 4, described control module 14 also comprises response message processing unit 144, described communication apparatus 20 receives the response message that is returned by receiving terminal, and response message is returned to the response message processing unit 144 of control module, described response message processing unit 144 judges whether to receive response message in setting-up time, if do not receive response message in setting-up time, controlling transmission unit stops sending to the data in transmit queue according to priority level order from low to high.Transmit queue is stopped after transmission wherein, and the packet of buffer memory continues buffer memory or is dropped.
the transmission of medical treatment Wave data is stopped up, frequent appearance networking is interrupted, the phenomenon that waveform pauses or loses, take massive band width in the transmission tone video information, affect the defectives such as transmission of other important medical informations, the present embodiment distributes priority level with different data based pre-defined rules, (for example occur congested at network in the situation that network is bad, in the situation that network signal is bad or bandwidth is not enough), for guaranteeing almost real-time and the reliability of transfer of data, the priority relation that the Various types of data transmission keeps certain to set in advance, such as: vital sign, treatment data＞GPS locator data＞audio, video data＞machine data, the first aid end stops the transmission to the low data of priority level, thereby reduced the data volume of uploading, reduced the probability of network congestion, the transmission of the data that are conducive to guarantee that priority level is high.
In another kind of embodiment, when the Internet Transmission quality is good, can again recover the transmission of some data.Therefore, described control module 14 also is configured to postpone less than setting-up time when the data packet acknowledgement of the current transmission of judgement, or the packet loss retransmission rate is lower than setting thresholding, and during the current state that has transmit queue to be in to stop transmitting, according to priority level order from high to low, the formation that is stopped at present transmission is restarted to set Transmission Time Interval according to it and carry out transfer of data.
The high priority data ordinal relation can be adjusted according to data significance level and concrete application scenarios.The high priority data that wherein priority is high sends, and can occupy even to stop transmitting the low data of other priorities, transmits smoothly to guarantee the high data of priority.On the basis that the highest priority data can be transmitted smoothly, then guarantee that the data of time high priority send, by that analogy.
in certain embodiments, in formation according to the character of data, sample rate that can be by reducing some data or video resolution or frame rate reduce the data volume of uploading data, for example for the inessential formation that needs the Wave data of real-time Transmission of buffer memory, can inessentially need the sample rate of the Wave data of real-time Transmission to be set to adjustable, make it can be according to predetermined condition transformed samples rate, for example, (for example do not receive replying of returning or network packet loss rate in setting-up time and surpass setting threshold) when the Internet Transmission poor quality or the data volume of transmission when surpassing a certain setting threshold, reduce the sample rate of these class data of this formation institute buffer memory.And for example, for the inessential formation that does not need the audio, video data of real-time Transmission of buffer memory, can inessentially not need resolution and/or the frame rate of the audio, video data of real-time Transmission to be set to adjustable, make it can be according to predetermined condition conversion resolution and/or frame rate, for example, (for example do not receive replying of returning or network packet loss rate in setting-up time and surpass setting threshold) when the Internet Transmission poor quality or the data volume of transmission when surpassing a certain setting threshold, reduce resolution and/or the frame rate of these class data of this formation institute buffer memory.
Structure based on above-described embodiment, can be suitable for simultaneously multiple transmission policy when the application transport strategy, below with applicable different Transmission Time Interval simultaneously and reduce sample rate or the resolution explanation when carrying out transfer of data, it stops the flow process of transfer of data and resume data transmission, as shown in Figure 5, comprise the following steps:
Step S21 according to the Transmission Time Interval that arranges separately reading out data and send to communication apparatus from individual queue, is uploaded to receiving terminal by communication apparatus by network.In an instantiation, control module is adopting the Packet Generation in transmit queue during to communication apparatus the mode with the multiple-transmission-line journey of packet piecemeal to send, and the real-time of transfer of data is provided from optimized transmission agreement aspect.
Step S22, control module receives the response message that is returned by receiving terminal.
Step S23 judges whether to receive response message in setting-up time.Receiving terminal receives and returns about receiving the response message of this packet after communication apparatus sends packet, communication apparatus sends to control module with response message, control module judges whether the time of reception of this response message surpasses the threshold time of setting, if, execution in step S24, if the time of reception of this response message does not surpass the threshold time of setting, continue execution in step S21.
Step S24, control module stops sending to the packet in transmit queue according to priority level order from low to high, then execution in step S25.Transmit queue is stopped after transmission according to circumstances wherein the packet of buffer memory to be continued buffer memory and waits for transmission next time or directly be dropped.
Step S25, if the inessential Wave data that needs real-time Transmission is arranged in the formation of current transmission, control module can be controlled the sample rate that reduces medical waveform (for example blood pressure waveform or body temperature waveform), if the inessential audio, video data that does not need real-time Transmission is arranged in the formation of current transmission, control module can also reduce video resolution and/or frame rate.Generally, for obtaining high-quality medical waveform, it is higher that the sample rate of medical treatment waveform all arranges, because some Wave data is not very important, and doctor's key is to see the trend of medical waveform, so after suitably reducing sample rate, can't affect the effect of medical waveform, therefore in the present embodiment, exchange the decline of transmitted data amount for the display quality of sacrificing medical waveform or video image, to guarantee the transmission of crucial and significant data.
Step S26, control module judges whether the current network transmission quality is enough good, the data packet acknowledgement that specifically judges current transmission postpones less than setting-up time, or the packet loss retransmission rate is lower than setting thresholding, if it is execution in step S27, otherwise continue to fetch data from the formation of current permission the transmission of data.
Step S27 restarts to set Transmission Time Interval according to it according to priority level order from high to low to the formation that is stopped at present transmission and carries out transfer of data.
In the present embodiment, in the measured situation of Internet Transmission matter, can restart transmission to the data in the formation that is stopped at present transmission according to priority level order from high to low, thereby make the lower data of priority level also can be transferred to receiving terminal, for the medical worker of receiving terminal provides more medical data and field data, be conducive to the doctor patient of first aid end is made diagnosis more accurately.
The pre hospital care system also comprises receiving terminal, central control system for example, and receiving terminal is used for receiving the data block that system sends before institute, is usually located in hospital or first-aid centre.In one embodiment, receiving terminal is recombinated according to the sequence notation of the data block that the first aid end sends the data block that receives, and the data that needs are shown send to display end and show.The described data that need to show comprise the real-time waveform data, for the real-time waveform data, receiving terminal is configured to allow the data of the current time that will not be transferred to when waveform shows to abandon and continues to show next data constantly, and require on its backstage the current time that is not transferred to data re-transmission until transmission success or retransmit set point number after still unsuccessful stopping retransmit, preserve complete data or preserve incomplete data in historical waveform.For showing the situation of real time medical information waveform almost or data in user interface, the handling process of receiving terminal comprises the following steps as shown in Figure 6:
Step S31, receiving terminal receives on its backstage the real-time waveform data that the first aid end transmits, and the sequence notation according to data block is set up data queue after receiving the real-time waveform data, make data block be combined into chronological Wave data in formation, after the data buffering in formation is a certain amount of, Wave data in formation is sent to display end together show, the discontinuity that can avoid like this display end waveform to show.
Step S32 judges that whether the data block quantity that lacks in formation is lower than setting threshold.In the present embodiment, the data block quantity that lacks in the length of data queue (being the quantity of data block in formation) based on data formation is variable, when data queue meets the data block quantity term (be lack in formation data block quantity lower than setting threshold) of disappearance, execution in step S33, otherwise continue execution in step S31.
Step S33 sends to display end with the real-time waveform data in data queue and shows.
At receiving terminal, the data of the current time that permission will not be transferred to when waveform shows abandon and continue to show the data in next moment, be in wait state thereby avoid when the data of current time are not transferred to waveform to show, can't show next data constantly, thereby cause the sense that pauses.By the quantity of missing data piece in the restriction formation, guaranteed the continuity that user interface waveform or data show in addition.
Transmission policy for individual queue, because control module is divided into different priority levels with data based real-time and importance, so transmission policy can also be set to for retransmitting after important data demand bust this, only to transmission success, for retransmitting after unessential data demand bust this, still unsuccessful after retransmitting set point number, stop transmission.Can also require after bust this whole re-transmission the again for the important data that do not need real-time Transmission, only to transmission success, for namely requiring the packet of a bust this after the important data transmission fails that needs real-time Transmission.
Data check information and important physical signs of patient information can adopt the TCP/IP mode to transmit, guarantee data integrity, other information adopt the UDP mode to transmit to improve transmission speed, and according to data check information, missing data are required to retransmit, and make up the UDP transmission and produce the defective of loss of data.
Above content is in conjunction with concrete execution mode further description made for the present invention, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
