Description

用于生理参数监测的一对多无线数据采集通讯方法 Many physiological parameter monitor for wireless data communication method of collection

技术领域 FIELD

[0001] 本发明涉及无线通讯技术领域,具体涉及一种用于生理参数监测的一对多的无线数据采集通讯方法。 [0001] The present invention relates to wireless communication technologies, and particularly relates to a physiological parameter monitoring for many wireless communication method of data collection.

背景技术 Background technique

[0002] 随着人们的健康意识和保健要求的日益增强,医疗模式由对症治疗向预防为主转变,对于人体健康状况监测的需求越发迫切。 [0002] With the growing awareness of people's health and health care requirements, mainly medical model to prevent changes from symptomatic treatment for the condition monitoring of human health needs more urgent. 伴随而来的网络的发展与嵌入式技术的普及,多生理参数监护系统与远程医疗领域迎来了一个快速发展的阶段。 Popularization and development of embedded technology accompanied by networks, multiple physiological parameter monitoring systems and telemedicine ushered in a stage of rapid development. 人体生理参数的监测主要是针对血压、脉搏、心电和体温等各种能够衡量人体健康状况的重要参数进行信息采集和数据分析,从而对疾病的诊断和预防提供重要的依据。 Monitor physiological parameters of the human body is mainly collect information and data for a variety of blood pressure, pulse, ECG and body temperature and other important parameters can measure the health status of the analysis to provide an important basis for the diagnosis and prevention of disease. 小型化,无线技术是未来监护系统发展的一个趋势。 Miniaturization, wireless technology is a trend of the future development of the monitoring system. 因此,嵌入式系统与无线技术在医疗监护系统领域的应用越来越广泛。 Therefore, the application of embedded systems and wireless technologies in the field of health care system more widely.

[0003] 针对多生理参数的无线数据传输方案,目前主流的选定RF射频无线数据通讯技术。 [0003] wireless data transmission scheme for multiple physiological parameters, the current mainstream of the selected RF radio frequency wireless data communications technology. RF射频模块接收生理参数检测节点发送的实时数据,并且将数据通过系统的无线局域网卡发送至无线终端的计算机上,同时实现数据的实时存储。 RF module RF receiver node detects physiological parameters of real-time data transmission, and transmits the data via the wireless LAN card on the computer system to the wireless terminal, while real time data is stored. 采用RF射频无线传输方案的系统能够期望实现诸如心电参数、血氧饱和度、血压、呼吸和体温等生命体征参数的多种生理信号的点对点实时无线传输,同时通过无线局域网完成数据的实时存储。 Real-time storage system using radio frequency wireless RF transmission scheme can be expected, such as real-time multiple point wireless transmission of physiological signals vital signs parameters ECG parameters, oxygen saturation, blood pressure, respiration and body temperature, while the completion of data over a wireless local area network .

[0004] 传统的一对多芯片的传输协议如图1所示,图中示意性地示出了一个接收端六个发射端的一对六形式的终端。 [0004] The conventional chip-to-many transmission protocols shown in Figure 1, is schematically illustrates a receiving end in the form of six six transmitter terminal couple. 在传统的传输协议下,接收端对发射端没有实际控制,发射端可以随时发射数据包,这导致了这种类型的芯片在应用多生理参数收集和监测方面具有以下不足之处: In the conventional transmission protocol, the receiver is not practical to control the transmitter, the transmitter may transmit a packet at any time, which led to this type of chip has the following shortcomings in application of physiological parameters and monitoring of the collection:

[0005] 1.由于无线通讯存在丢包情况,所以通常每次通讯无论是接收还是发射都是双向的,也就是接收端在接到信号以后还会自动回复一个确认信息。 [0005] 1. The packet loss due to radio communication, it is usually each correspond either receiving or transmitting are bidirectional, i.e. the receiving terminal after receiving a confirmation signal also automatically reply message. 如果没有收到确认信息,系统会自动重新发送几次。 If the acknowledgment is not received, the system will automatically resend several times. 尽管可以通过修改单片机的寄存器来修改重新发送确认信息的次数使重新发送的次数降低,但也会造成通信效率的降低。 Although it is possible to modify the number of re-send a confirmation message that the number of retransmissions is reduced, but will result in reduced communication efficiency by modifying the MCU register.

[0006] 2.无线通讯在传输信号时,接收端和发射端都必须在同一个物理频段上,比如2.45GHz,否则天线无法收到数据。 [0006] 2. The wireless communications signal transmission, the receiver and transmitter must be on the same physical frequency band, such as of 2.45 GHz, the antenna can not receive data otherwise. 当天线收到数据后,射频芯片会自动判断信号包里的地址位,如果地址是自己期待的就会接收数据包,如果不是就放弃。 After receiving the data antenna, RF chip will automatically determine the address signal of the bag, if the address is looking forward to their own will receive data packets, if not to give up. 这种单一物理频段的限制使得应用的局限性较大。 This limitation single physical limitations of the application such that the band is large.

[0007] 3.由于同时有多个发射端在一个网络里面,且不同发射端的数据包可能在同一个时间向接收端发送数据,因此增加了数据包在传输过程中相互影响的可能性。 [0007] 3. Since a plurality of simultaneously transmitting terminal inside a network, and packets of different transmitting end to the receiving end may transmit data at the same time, thus increasing the possibility of mutual influence packet during transmission. 并且,一个接收端在一个时间点只能处理一个数据包,第二个数据包会自动放弃,这样严重影响了信息传输的速率和成功率。 And, a receiving side can handle at one time point a data packet, the second packet will be automatically released, and this seriously affected the rate of information transfer success rate.

[0008] 为了解决上述问题,需要一种能克服上述缺点的新的一对多通讯方法,解决传输效率低下、成功率低的问题,以更好的实现在应用于多生理参数收集和监测领域。 [0008] To solve the above problems, a new-to-many communication method overcomes the aforementioned disadvantages, transmission inefficiencies solve the problem of low success rate, it is applied to achieve a better collection and monitoring physiological parameters in the art .

[0028] 无线收发模块211用于接收来自接收端220的控制指令,并通过无线通道向接收端220返回一个表示收到控制指令的确认信息包,并且,该确认信息报中还包括存储于缓存模块212的生物数据。 [0028] The wireless transceiver module 211 for receiving control commands from a receiving terminal 220, and returns the acknowledge packet received represents a control command to the receiving terminal 220 through a wireless channel, and the acknowledgment message further comprises information stored in the buffer biological data module 212.

[0029] 缓存模块212,用于临时保存数据采集电路213输出的生物数据,并且在无线收发模块211收到接收端220的控制信号时,将临时保存的生物数据加入上述确认信息包中。 [0029] The cache module 212, a biometric data acquisition circuit 213 temporarily stores the data output, and when the radio transceiver module 211 receives a control signal receiving terminal 220, the temporarily stored biometric data added to the confirmation packet.

[0030] 数据采集电路213,根据前端处理电路214的输出结果得到生物数据。 [0030] The data acquisition circuit 213, a front-end to obtain biometric data processing circuit 214 outputs the result.

[0031] 前端处理电路214,用于将传感器215采集到的生物数据进行前期处理。 [0031] The front-end processing circuit 214 for the sensor 215 to collect biological data pre-processing.

[0032] 传感器215,用于采集生物数据,可选用本领域常用的各自生物特征或体征数据采集的传感器。 [0032] The sensor 215, for collecting biological data, the choice of the respective sensor commonly used in the art or signs of the biometric data acquisition.

[0033] 接收端220用于按照预先设置的数据索取顺序,向发射端索取并存储数据。 [0033] The receiving terminal 220 to obtain the order for the data set in advance to obtain and store data to the transmitting end. 在接收端220中: At the receiving end 220:

[0034] 无线收发模块221,用于按照索取顺序设置模块222中的数据索取顺序,向发射端发送控制指令,来索取收到控制指令的发射端所采集的生物数据。 [0034] The wireless transceiver module 221 for setting data obtained from the sequence block 222 in accordance with the order request, transmits a control command to the control command request received biometric data acquired transmitting end to the transmitting end.

[0035] 索取顺序设置模块222,用于设置接收端220向各发射端索取数据的顺序。 [0035] The request module 222 sequentially disposed, is provided for each receiving terminal 220 to obtain the data transmitting end sequence. 设置索取数据的顺序的方法例如是由工作人员进行设置。 Set the order request data is set, for example, methods by the staff.

[0036] 优选地,索取顺序设置模块222根据各个发射端的数据采集频率,设置索取数据的顺序。 [0036] Preferably, the setting module 222 sequentially obtain the data acquisition rate of each transmitting end is provided in order to obtain data. 具体地,在数据索取开始之前,索取顺序设置模块222获取每个发射端的传感器的采样率(数据采集频率),并根据采样率来设定采取数据的顺序。 Specifically, before the start request data, the setting module 222 acquires order to obtain the sampling rate for each sensor transmitting end (data acquisition rate), and sets the data sequence taken in accordance with the sampling rate. 比如,有的传感器的采样频率为2000Hz,即一秒钟采集2000个数据,有的传感器一秒钟只采集1000个数据,这样,2000Hz采样率的发射端就会比1000Hz采样率的发射端采集数据更频繁2倍。 For example, the sampling frequency is 2000Hz and some sensors, i.e., a second data acquisition 2000, a second sensor only some 1000 data collected, so the transmitter will capture 2000Hz sampling rate than the sampling rate 1000Hz transmitting end 2 times more frequent data. 若不考虑采样频率而按顺序索取,则会降低数据传输的效率。 Irrespective of the sampling frequency in order to obtain, data transmission efficiency will decrease.

[0039] 根据本发明的传输通讯方法,数据接收端能控制数据发射端的发射顺序和时机,即数据接收端同时也行使了发射的功能,而数据发射端也同时行使了接收的功能。 [0039] The transmission communication method of the present invention, the data receiving side can control the data transmission order and timing of transmitting end, i.e., the data receiving end also functions exercised transmitted, the data transmitter also exercise the function of receiving. 具体而言,对于一个接收端和一个发射端之间的通讯,当发射端发送一个信息包给接收端后,接收端会自动回复一个确认信息包以确认收到该信息包。 Specifically, for a communication between the receiving end and a transmitting end, when the transmitting terminal transmits a packet to the receiving end, the receiver will automatically return an acknowledgment packet to confirm receipt of the packet. 根据本发明的通讯方法,将要通讯的信息包加载到该确认通信包中进行传输,换言之,将发送端通过传感器采集到的数据以确认信息包的形式从发射端传输到接收端。 The communication method of the present invention, the communication packet to be loaded into the communication packet for transmission confirmation, in other words, the transmitting end in the form of acknowledgment packets transmitted from the transmitting end to the receiving end of the data collected by the sensor. 例如,在医疗参数采集的应用中,传感器采集到的生理数据即为要传输的数据。 For example, in medical applications the acquisition parameters, physiological data collected by the sensor is the data to be transmitted.

[0040] 图3示出了根据本发明的一对多无线数据传输通讯方法。 [0040] FIG. 3 shows a data transmission in accordance with multiple wireless communication method of the present invention.

[0041] 首先在步骤300,当数据传输开始之前,数据接收端设置从数据发射端索取数据的顺序。 [0041] First, in step 300, when the data transfer starts before, the data receiving end terminal disposed sequentially from the data request transmitting data. 根据本发明的方法适用于具有多个数据发射端的系统,因此需要对数据发射端的索取顺序进行预先设定。 The method of the present invention is applicable to a plurality of data transmitting end system, it is necessary to obtain the data transmitting end a predetermined order. 例如,可以按照数据发射端的编号顺序索取,或者按照其他任意设定的规则进行索取。 For example, the sequential order to obtain the data transmitting end, according to the request or by other rules arbitrarily set. 可以通过设定数据发射端的数据地址或通道的顺序来设定索取的顺序。 It may be set in order to obtain data by sequentially setting addresses or data channel of the transmitting end.

[0042] 在步骤310,当数据传输开始后,数据接收端开始先对所设置的索取顺序中的第一数据发射端发送一个控制指令。 [0042] In step 310, when the data transmission begins, the data receiver to start to obtain a first sequence of data provided in the transmitting end transmits a control instruction. 该控制指令可以是一个很短的信息包及其他获得信息的指令。 The control command may be a very short packet and other instructions for obtaining the information. 例如,首次发射一个OxFC指令到发射端,发射端将反馈给接收端其所在的独特ID信息,如OXOlo For example, a first launch OxFC instruction to the transmitting end, the transmitting end is fed back to its unique ID information in the receiving terminal, such as OXOlo

[0043] 接着在步骤320,该第一数据发射端收到该数据接收端发送的控制指令后,发送确认信息包,该信息包中包含了该第一数据发射端之前采集到的数据,如生理数据等。 After [0043] Next, at step 320, the first data transmitting end receives a control instruction transmitted from the data receiving terminal, sending an acknowledgment packet, the packet contains data collected prior to the first data transmitting end, such as physiological data. 所采集到的数据加入到该确认信息包中后,连同确认信息一起返回给数据接收端; After the collected data is added to the acknowledgment packet, together with the acknowledgment information returned to the data receiving terminal;

[0044] 在步骤330,数据接收端收取到第一数据发射端发出的包含采集到的数据的确认信息包后,修改其数据地址或通道,以改变索取数据的对象为索取顺序中的下一个发射端。 After [0044] In step 330, the data reception side receive the acknowledgment packet comprising a first data collection to data sent by the transmitter, or modify the address data channel, the data request to change the object to obtain a sequence of The transmitting end. 根据本发明的每个数据发射端均有其自己唯一的地址,因此每个数据发射端相互之间没有影响; According to the present invention each data transmitter has its own unique address, so that each data between the transmitting end does not influence each other;

[0045] 在步骤340中,数据接收端向下一个数据发射端,即第二数据发射端发送索取数据指令,该指令与步骤310中第一次发射的指令相类似,但所针对指令对象不同,如发射端产生了反馈信号,则同时登记与第一次数据发射不同的地址信息; [0045] In step 340, the data receiving side down a data transmitting end, i.e. a second data transmitting end transmits the data request command, the command instruction transmitted in step 310 is similar to the first, but with different instructions for the objects , such as the transmitter generates a feedback signal, with the first registered simultaneously transmit different data address information;

[0046] 在步骤350,该第二数据发射端收到该数据接收端发送的控制指令后,发送确认信息包,该信息包中包含了该第二数据发射端之前采集到的数据,如生理数据等。 After [0046] In step 350, the second data transmitting end receives a control instruction transmitted from the data receiving terminal, sending an acknowledgment packet, the packet contains data collected prior to the second data transmitting end, such as a physiological data. 所采集到的数据加入到该确认信息包中后,连同确认信息一起返回给数据接收端; After the collected data is added to the acknowledgment packet, together with the acknowledgment information returned to the data receiving terminal;

[0047] 在步骤360,判断数据的数据传输是否完毕,例如是否到达了所设置的索取顺序中的最后一个数据发射端,或者是否按照预先设定的规则完成了数据传输的任务。 [0047] In step 360, the data transmission is determined whether the data is completed, for example, it has reached the last data request transmitting end disposed in the order, or whether or not the data transfer tasks in accordance with predetermined rules. 例如,已经传输了所设定的数据量或经过了所设定的传输时间等等。 For example, the amount of data transmission has been set has elapsed or the transmission time is set and the like. 如果数据未传输完毕,则返回步骤330,数据接收端修改其数据地址或通道,向下一个数据发射端发射控制信号索取数据。 If the data is not transmitted, the process returns to step 330, the data receiving end or modify the address data channel, the next data transmission side transmits the control signal to obtain data. 重复步骤330-350直到数据传输完毕。 Repeat steps 330-350 until the data transmission is completed.

[0048] 图3中示出的第一数据发射端、下一数据发射端和第二数据发射端只是示意性地命名,数据发射端的选择可以按照接收端索取的需要进行任意设定。 [0048] FIG. 3 shows a first data transmitting end, the next data transmitting end and a second data transmitting end only schematically name, select the data transmitting end can be arbitrarily set as required to obtain the receiving end.

[0049] 根据本发明的一对多通讯方法,不仅可以解决现有技术中一对多通讯的问题,而且完全消除了数据发射端相互影响的可能性,从而提高了通讯速率和通讯质量。 [0049] The to-many communication method of the present invention, not only can solve many problems of the prior art communications, and completely eliminates the possibility of the influence of the data transmitting end to each other, thereby increasing communication speed and communication quality. 并且,每个数据发射端都有各自的时钟和缓存系统,即使该发射端采集完数据后,数据接收端还没有索取到该发射端时,该发射端可以对采集到的数据进行缓存,避免了数据丢失和数据延时。 Then, the data transmitting end each has its own clock and the cache system, even after the transmitting end collecting the data, the data receiver has not request to the transmitting end, the transmitting end may buffer data collection to avoid data loss and data latency. 当轮到该数据发射端时,它会把存在缓存里的数据和自己的时钟信息一起返回给数据接收端。 When the turn data transmitting end, it will present the data in the cache and returned with its own clock information to the data reception terminal.

[0050] 特别地,数据的延时是通过缓存和时间点来复原的,延时时间大约为发射端的数量*lms。 [0050] In particular, the delay through the buffer and the data is restored to the point in time, the delay time is about the number of transmitting end * lms. 即,当有十个发射端时,每个发射端可能存在的最大延时应该是1ms0 That is, when the ten transmitting end, the transmitting end each maximum possible delay should be 1ms0

[0051] 根据本发明的一个优选实施例,本发明的一对多通信方法特别适用于包含多个具有不同采样频率的发射端系统。 [0051] According to a preferred embodiment of the present invention, many communication method of the present invention is particularly suitable for systems having a transmitter comprising a plurality of different sampling frequencies. 在这种情况下,在数据传输开始之前,接收端获取每个发射端的传感器的采样频率,并根据采样率来设定采取数据的顺序。 In this case, before data transmission begins, the receiver acquires a sampling frequency of each sensor the transmitting end, and to set the order of the data taken according to a sampling rate. 比如,有的传感器的采样频率为2000Hz,即一秒钟采集2000个数据,有的传感器一秒钟只采集1000个数据,这样,2000Hz采样率的发射端就会比1000Hz采样率的发射端采集数据更频繁2倍。 For example, the sampling frequency is 2000Hz and some sensors, i.e., a second data acquisition 2000, a second sensor only some 1000 data collected, so the transmitter will capture 2000Hz sampling rate than the sampling rate 1000Hz transmitting end 2 times more frequent data. 若不考虑采样频率而按顺序索取,则会降低数据传输的效率。 Irrespective of the sampling frequency in order to obtain, data transmission efficiency will decrease.

[0052] 图4示出了示例性的一个系统里有两个2000Hz和两个1000HZ的数据发射端的索取顺序。 [0052] FIG 4 illustrates an example of a system has two data and two 2000Hz 1000HZ order to obtain emission end. 如图4所示,数据接收端通过收集所有数据发射端的采集频率后,计算分配的数据索取顺序如下: 4, the data receiver all the data collected by the acquisition frequency of the transmitting end, the data obtained from the distribution is calculated in the following order:

[0053] 首先索取高频率的2000Hz采集频率的第一发射端,然后索取低频率的1000Hz采集频率的第二发射端,然后再索取高频率的2000Hz采集频率的第三发射端,之后再索取高频率的2000Hz采集频率的第一发射端,然后索取另一低频率的1000Hz采集频率的第四发射端,然后索取高频率的2000Hz采集频率的第三发射端,完成一个数据索取周期。 A third acquisition frequency transmitter 2000Hz 2000Hz the transmitting end a first acquisition frequency of the [0053] first obtain a high frequency and a low frequency to obtain a second acquisition frequency of 1000Hz transmitting end, and then to obtain a high frequency, then after high Request a first acquisition frequency 2000Hz frequency transmitter and obtain other low frequency 1000Hz fourth transmitter frequency acquisition, and then collected to obtain a high frequency of 2000Hz third frequency transmitter, to complete a data request cycle. 这样,高采集频率(2000Hz)的发射端大约4ms后循环扫描一次,而低采集频率(1000Hz)的发射端大约8ms循环扫描一次,高频采集的发射端的采集频率是低频发射端的两倍。 Thus, the transmitting end high acquisition frequency (2000Hz) of a scan cycle after approximately 4ms, low acquisition frequency (1000Hz) is about 8ms transmitting end a scanning cycle, a high-frequency transmitter acquisition frequency is twice the acquisition of low frequency transmitter. 同时,因为采样率越高,准备好数据包的速度也就越快,因此同一个传感器的两次索取指令之间的时间,高频发射端也比低频发射端的缩短了一半。 Meanwhile, since the higher the sampling rate, good speed packet ready sooner, the time difference between the same two instructions to obtain a sensor, a high-frequency transmitter transmitting the low-frequency side than halved.

[0054] 特别地,根据本发明的无线传输协议,并不仅仅适用于nRF芯片,对于所有能进行双向通讯的无线通讯,使用该协议都可以实现一对N的通讯。 [0054] In particular, according to the wireless transmission protocol of the present invention is not only applicable to nRF chip, capable of two-way communication to all wireless communication, the protocol can be implemented using a pair of N communication. 特别地,根据本发明的无线传输协议不局限于无线传输系统。 In particular, according to the wireless transmission protocol of the present invention is not limited to a wireless transmission system. 凡是能实现一对一传输的通讯,都可以通过使用该协议,在不增加接收端和保证即时性的情况下,实现一对多传输。 One who can achieve communication transmission, are available through the use of this protocol, without increasing the receiving end of the case and ensure real-time, to achieve many transmission.
