具体实施方式
体现本发明特征与优点的典型实施方式将在以下的说明中详细叙述。应理解的是本发明能够在不同的实施方式上具有各种的变化,其皆不脱离本发明的范围,且其中的说明及图示在本质上是当作说明之用,而非用以限制本发明。
如前所述的,通信应用的某些持续变化的信息将是通过采集得到的,例如,GPS应用中的全球定位信息,是随着所在通信设备的移动而持续变化的,通过数据传输使得其它通信设备得以获知相关的情况,例如,当前所在的具体位置、移动的速度、所在具体位置的海拔高度等,具体内容将由全球定位信息中定义的内容确定。
然而,通信设备之间对全球定位信息所进行的传输中,通常需要对全球定位信息进行压缩,以支持全球定位信息的大容量高频率传输。现有的由全球定位信息所实现的通信方式常见的有两种,一为DMR(数字移动无线)标准,另一则为摩托罗拉所提供的基于NMEA(National Marine Electronics Association,美国海用电子设备制定的标准格式)格式的压缩通信过程。
其中,DMR标准是通过UDT(UDP-based Data Transfer Protocol,基于UDT的数据传输协议)数据承载全球定位信息,即便最短的格式也需要两帧数据,即1个UDT数据头和1个UDT数据块,这将无法实现较高压缩效率,并且其所对应的数值范围也无法适用于进行高速移动的通信设备。
而摩托罗拉所提供的基于NMEA格式的压缩通信方式虽可对全球定位信息实现压缩,但由于其为了解决压缩过程中产生的各种问题而不断的延长了压缩后的信息宽度,进而难以得到数据的边界线,从而导致压缩效率不高的局限性。
鉴于此,本发明提供了一种实现信息压缩的通信方法,以实现通信设备中信息的更高效的压缩。
在一个实施例中,具体的,该方法如图1所示,包括:
步骤S110,提取应用信息中的采集信息,将采集信息进行转换,获得二进制数据的采集信息。
应用信息为通信设备中任一通信应用所产生的,用于准确提供当前所对应的状态,如,位置、移动状态等。相对应的,应用信息中包含了一种或者多种采集信息,采集信息将是对当前所对应的状态进行采集所得到的,如,位置采集、速度采集等。
例如,该应用信息可为GPS应用产生的全球定位信息,或者,北斗装置的全球定位信息等,全球定位信息中包含了一种或者多种采集信息,其中,该采集信息可为其中一种,例如位置信息;采集信息也可根据需要设置多种,例如除了位置信息之外,还设置了速度信息、海拔高度信息等。
应用信息除了包含采集信息之外,其根据定义的信息格式还包含了其它的一些信息,为保证信息的有效性,将提取应用信息中的采集信息,并转换得到二进制数据的采集信息,以屏蔽无用信息,减少冗余数据,提高压缩处理的针对性。
其中,所进行的转换为格式转化等,以得到适于传输的二进制数据的采集信息。
需要说明的是,通信设备之间的通信定义的信息格式将是无符号的二进制形式的,因此,预处理得到的二进制数据的采集信息也将是无符号的二进制形式的。
例如,对于采集信息是位置信息的本次传输信息而言,其可完整表示了所在的地理位置,而对于采集信息是速度信息、海拔高度信息等线性变化信息时,本次传输的则其变化信息,例如,表示了速度的变化信息等。
步骤S130,比对获得的二进制数据的采集信息和存储的基准信息得到信息差分,信息差分携带有获得的二进制数据的采集信息相对存储的基准信息的低位变化信息。
将选取某次传输作为后续信息传输和信息接收中进行还原所对应的参考点。其中,该参考点可以是首次传输,也可以是上一次传输,还可以是在后续传输中再次选定的,该参考点所对应的二进制数据的采集信息即为基准信息,并对基准信息进行存储,以供后续传输和信息接收中使用。无论如何选取参考点,对于发送端和接收端而言,所采用的参考点必须一致,以为信息的压缩传输提供准确性保障。
如若参考点为首次传输,则在通信设备开机时将首次传输的二进制数据的采集信息进行存储。
如若参考点为上一次传输,则在每次进行传输的过程中,将本次传输的二进制数据的采集信息存储为基准信息,以便于下一传输过程读取。
此基准信息的设置可以如约定进行灵活地设置。根据基准信息所得到的信息差分可以是相对参考点发生变化的低位变化部分,也可以是相对变化的差值。
若信息差分是相对基准信息发生变化的低位变化部分,则读取存储的基准信息,将获得的二进制数据的采集信息和存储的基准信息逐位进行二进制位的比对,得到本次传输中相对存储的基准信息的低位变化部分,该低位变化部分即为信息差分。
若信息差分是相对基准信息的差值,即相对基准信息进行比对计算即可得到。
信息差分指示了应用信息中持续变化信息所对应的动态变化,例如,若本次传输和基准信息发生了偏离,则该信息差分即为本次传输中相对基准信息的偏离部分;二进制数据的采集信息和读取的基准信息未发生变化,则该信息差分将为0。
例如,若该采集信息为位置信息,该位置信息包含了经度信息和纬度信息,经度信息是完整表示经度的二进制数据,纬度信息是完整表示纬度的二进制数据。由此所得到的信息差分即为相对存储的基准信息中发生变化的二进制数据,或者差值,其是与经度和纬度相对应的。
若采集信息为速度信息,则为实现该速度信息的传输,每一次所进行传输的将是对应的速度变化信息,也就是说,由此所得到的信息差分即为本次传输的速度变化信息中相对作为基准信息存在的速度变化信息发生了变化的二进制数据。
为得到相对参考点发生了变化的二进制数据,在存储的基准信息的基础之上对提取的二进制数据 的信息逐位进行二进制位的比对,以得到本次传输的信息差分,该信息差分为本次传输信息相对参考点发生了变化的二进制数值。
步骤S150,根据信息差分得到本次传输的信息子帧。
信息差分包含了二进制数据的采集信息相对基准信息的低位变化部分。对于提取所获得的采集信息,从高位至低位包括了若干二进制数据,随着采集信息相对存储的基准信息之间由小到大或由大到小的持续变化,比对所得到的信息差分将是本次传输中发生变化的部分。
根据信息差分得到承载信息变化的信息子帧,信息子帧将使得信息差分得以通过一个或者多个帧的形式传输出去。对于多个连续的信息子帧而言,接收端其可根据所在二进制数据的采集信息中的顺序拼装在一起形成本次传输中二进制数据的采集信息发生变化的部分。
步骤S170,传输得到的信息子帧。
得到承载信息变化的信息子帧之后,将其传输至相应的接收端。在优选的实施例中,将对其进行按序传输,例如,可根据其在采集信息中的顺序进行传输,以保证后续接收的有序性。
在一个实施例中,承载了信息变化的信息子帧所进行的传输可由通信信元实现。其中,该通信信元的数据格式可包括信元头和信元体,该信元体中容纳了若干个承载信息变化的信息子帧,即,若干个信息子帧将在信元体中按照高位至低位的顺序进行设置,进而通过该通信信元实现信息子帧的传输。
在一通信信元无法容纳多个信息子帧时,各信息子帧按照高位至低位的顺序进行多次通信信元的独立传输来完成所有信息子帧的传输。
通过将如上所述的过程应用于作为发送端的通信设备,使得应用信息中采集信息相关内容的传递仅需要通过承载信息变化的信息子帧实现,而不需要对整个采集信息进行传输,大为提高了信息压缩效率和传输效率,进而避免传输过程中的控制信道拥塞。
需要说明的是,本申请所说的信息子帧的传输是在发送端和接收端之间进行的,也就是说,本发明所说的信息子帧的发送是由发送端执行的,信息子帧的接收则是由接收端执行的。
并且相对于每次传输当次数据与上次传输数据的差值,可能由于丢失数据,导致接收端回复数据出现偏差,本申请由于每一次传输均只是通过信息子帧传输低位变化信息,再通过一个基准信息进行恢复,即便发生一次或多次信息子帧的丢失或者出现其它错误,由于接收端再次接收到正确的信息子帧时,都可以直接使用基准信息进行恢复,获得正确的采集信息,传输的准确性有很大提高。
进一步本申请中,所有二进制数据,如二进制数据的采集信息及存储的基准信息,都可以是紧缩格式的二进制数据。
进一步,在如上所述的传输过程中,通过信息子帧来对采集信息的低位变化信息进行传输,在接收端使用基准信息进行恢复,在某些场景下可能出现以下情况。
当发送端当前的采集信息相对于基准信息相差越来越大后,当前提取的采集信息相对存储的基准信息,发生变化的低位数据也变得越来越大,原来可能只需要两个帧就能装下的变化数据,需要三个帧才能装下,导致压缩效率越来越低,以位置信息为例:
基准信息为:经度:1010100001000101001001102
           纬度:100000001110001100011112
发送端在小范围内移动时,可能发生变化的只是最后8位数,两个子帧就可以放下,当发送端经度从1010100001000101111111112向1010100001000110000000002变化时,数值上只加了“1”,但发生变化的位数已经变成了10位,经度和纬度一起导致必须用四个帧才能装下,压缩效率一下子降的很低,不能满足有些需要很高效率压缩的场景。
因此,为改善在这种情况下的压缩效率,本申请提供了两种实施方式:
1、根据实际情况,例如终端的移动速度等信息估计终端最快过多长时间会到达临界值,预设一个时间周期,定时更新基准信息,预设时间周期到达即使用发送端当前的二进制数据的采集信息更新发送端以及接收端存储的基准信息,那么相对于新的基准信息,又可以进行高效的压缩。
2、预先根据压缩效率的实际需要,设置一个边界值,采集信息相对基准信息的变化达到边界值,那么即说明,继续使用旧的基准信息,压缩效率将会大大降低。发送端每次获得二进制数据的采集信息后,都进行判断,判断所述二进制数据的采集信息相对于所述存储的基准信息的变化是否达到预设的边界值,若为是,则使用发送端当前的二进制数据的采集信息更新发送端以及接收端存储的基准信息,以保持数据压缩的高效,若为否,则继续比对获得的二进制数据的采集信息和存储的基准信息得到信息差分,传输信息差分。
进一步,本申请提供了三种不同的更新方法:
第一种:
发送端向接收端传输完整的二进制数据的采集信息;
接收端接收到该完整的二进制数据的采集信息后,将存储的对应发送端的基准信息更新为该完整的二进制数据的采集信息,并向发送端发送传输成功确认;
发送端在收到接收端的传输成功确认后,将存储的基准信息更新为所述完整的所述二进制数据的采集信息。需要说明的是,在其他实施例里,发送端也可以在收到接收端的传输成功确认前,将存储的基准信息更新为所述完整的所述二进制数据的采集信息,只是等待传输成功确认,再进行携带信息差分的信息子帧的传输。
需要说明的是,发送端可以直接在向接收端传输完整的二进制数据的采集信息的消息里增加到达边界指示,以使接收端可以直接通过读取该指示,将存储的对应发送端的基准信息更新为该完整的二进制数据的采集信息;也可以直接发送完整的二进制数据的采集信息,接收端在收到后判断该信息为完整的二进制数据时,判断需要将存储的对应发送端的基准信息更新为该完整的二进制数据的采集信息。
进一步,如果发送端没能收到传输成功确认,那么说明可能出现了数据丢失,那么可以再次重传当前的完整的二进制数据的采集信息。
第二种:
由接收端判断还原获得的二进制数据的采集信息与存储的相应发送端的基准信息相比,变化是否达到预设的边界值,若达到,则将存储的对应发送端的基准信息更新为还原获得的二进制数据的采集信息,并向发送端发送传输成功确认;
发送端在传输得到所述信息子帧之后,判断是否收到接收端的传输成功确认,若为是,则认为接收端已经更新成功,并将存储的基准信息更新为当前获得的完整二进制数据的采集信息。需要说明的是,在其他实施例里,发送端也可以在收到接收端的传输成功确认前,将存储的基准信息更新为当前获得的完整的二进制数据的采集信息,只是等待传输成功确认,再进行携带信息差分的信息子帧的传输。
第三种:
发送端在传输的信息子帧中增加到达边界指示;
接收端获取到到达边界指示后,则将存储的对应发送端的基准信息更新为还原获得的二进制数据的采集信息,并向发送端发送传输成功确认;
发送端在传输得到所述信息子帧之后,判断是否收到接收端的传输成功确认,若为是,则认为接收端已经更新成功,并将存储的基准信息更新为当前获得的完整二进制数据的采集信息。需要说明的是,在其他实施例里,发送端也可以在收到接收端的传输成功确认前,将存储的基准信息更新为当前获得的完整的二进制数据的采集信息,只是等待传输成功确认,再进行携带信息差分的信息子帧的传输。
以上只是三种实施方式的举例,实际使用中还会有其他传输完整的二进制数据的采集信息的方式。
基于如上所述的实施方式,将设置边界值,在持续进行的传输中,如上所述的方法还包括:
在获得二进制数据的采集信息之后,判断二进制数据的采集信息相对于存储的基准信息的变化是否达到预设的边界值,若为是,则在传输得到的信息子帧之后,判断是否接收到接收端的传输成功的确认,在收到接收端的传输成功的确认后,将存储的基准信息更新为完整的二进制数据的采集信息,若为否,则执行步骤130。
通过边界值来进行传输控制,一方面的,以边界值作为依据,一旦本次传输中二进制数据的采集信息相对存储的基准信息的变化达到边界值,则对作为参考点而存储的基准信息进行更新;并且对于远端的接收而言,达到边界值的此次传输必须在传输成功后进行确认,以便于发送端能够接收到接收端的传输成功的确认,进而确认当前所进行的传输未发生丢失或者其它错误,由此保证传输的可靠性和基准信息的准确性。
另一方面的,如前所述的,存储的基准信息是某一次的二进制数据的采集信息,即该次传输中,都将存储的基准信息更新为本次传输的二进制数据的采集信息,以供后续传输使用。
对于二进制数据的采集信息和存储的基准信息之间,将直接比对得到二进制数据的采集信息和存储的基准信息之间的变化,以根据该变化和边界值来控制发送端中基准信息的更新和发送端所进行的传输成功的确认,进而也将相应控制接收端中为此发送端存储的基准信息的更新。
通过上述预设的边界值的控制,将间隔地在传输中进行可靠性的确认以及通过确认无误的二进制数据的采集信息来更新基准信息,实现了发送端和接收端中基准信息的校正,保证了发送端和接收端之间传输的一致性,避免可能存在的误差放大问题。
在边界值的控制下,对于发送端而言,只有在接收到接收端的传输成功的确认之后,方可继续进行信息子帧的传输,而对于相应基准信息的更新,可以在接收端传输成功的确认之前执行,也可以在接收端传输成功的确认之后执行,在此不进行限定。
在二进制数据的采集信息达到预设的边界值时,二进制数据的采集信息的传输方式可以是进行二进制数据的采集信息的完整传输,但也可以是其他的传输方式。例如,也可以是直接传输以差值形式存在的信息差分,还可以仍然采用低位变化信息的形式,甚至于在低位变化基础上增加几个高位来进行传输,在此不进行限定,只需要在成功完成传输后返回确认即可。
因此,在一个实施例中,如上所述的方法还包括:
在获得二进制数据的采集信息之后,判断二进制数据的采集信息相对于存储的基准信息的变化是否达到预设的边界值,若为是,则在传输得到的信息子帧之后,判断是否接收到接收端的传输成功的确认,在收到接收端的传输成功的确认后将存储的基准信息更新为完整的二进制数据的采集信息。
进一步的,在一个实施例中,相对于存储的基准信息,如果二进制数据的采集信息存在高位变化,即如前所述的,发送端当前的采集信息相对于基准信息相差越来越大,进而达到或者超出了预设的边界值,因此,本次传输中,应当对存储的基准信息进行更新,以避免高位变化所带来的占用帧数量较多的问题。
在本发明的方案中,仅通过配置边界值,在采集信息和基准信息之间的变化达到边界值的情况下接收端向发送端返回确认即可确保传输的可靠性和准确性,并且也避免了采集信息中高位变化所造成的帧浪费的问题,通过保证很高的压缩率。如上所述的过程将适用于位置信息和各种线性变化信息的传输,以为此类信息的传输提供了高的压缩率和传输效率,线性变化信息包括了诸如速度信息、温度信息、海拔高度信息等。
进一步的,在本实施例中,如上所述的方法还包括:
在获得二进制数据的采集信息之后,判断二进制数据的采集信息相对于存储的基准信息的变化是否达到预设的边界值,若为是,则在信息子帧中增加采集信息到达边界值指示。
通过信息子帧中存在的到达边界值指示,使得接收端获知需对当前信息子帧的成功传输向发送端发送传输成功确认,并且在通过信息子帧所进行的还原获得二进制数据的采集信息之后,更新本接收端为发送端存储的基准信息,使存储的基准信息更新为还原获得的二进制数据的采集信息。
在此需要特别说明的是,二进制数据的采集信息及存储的基站信息均为紧缩格式的二进制数据。
如图2所示,在一个实施例中,如上所述的采集信息为位置信息,该步骤S110包括:
步骤S111,提取应用信息中的位置信息。
若应用信息中包含了位置信息,将直接由应用信息提取出位置信息,其中,该位置信息包括经度信息和纬度信息,以通过经度和纬度实现定位。
步骤S113,通过位置信息中经度信息和纬度信息的转换,以获得二进制数据的采集信息。
如前所述的二进制数据的采集信息为紧缩格式的二进制数据。在进行位置信息的转换即为紧缩格式的转化,以适应于位置信息的传输。其中,紧缩格式的转化包括平面化处理位置信息中经度信息和纬度信息的过程,以及精度调整运算的过程。
由位置信息中获取得到经度信息和纬度信息,并分别将经度信息和纬度信息转化为紧缩格式,以形成紧缩格式的位置信息,即二进制数据的采集信息。
紧缩格式指的是无符号整数的数据形式,也就是说,分别将获取得到的经度信息和纬度信息转化为无符号整数的数据形式,进而由转化得到的一串无符号整数形成本次传输信息。
通过紧缩格式的转化,将对位置信息进行了优化压缩,从而有效地摈弃了无用信息,提高了后续信息传递的有效性,有助于提升位置信息传输容量。
需要说明的是,由于应用信息中可包含了多种采集信息,因此,除了位置信息之外,采集信息还可为线性变化信息,例如,速度信息、海拔高度信息,对于此类采集信息,其所进行的转换过程为:运算线性变化信息和上一采集的线性变化信息之间紧缩格式的变化信息,该变化信息即为二进制数据的采集信息。
与位置信息的复杂程度所不同的是,在应用信息中,该线性变化信息本身即为紧缩格式的,因此,并不需要进行紧缩格式转化,而只需要获取两个线性变化信息之间发生的变化,即变化信息。
进一步的,在本实施例中,如图3所示,该步骤S113中涉及的平面化处理包括:
步骤S1131,由位置信息得到经度信息和纬度信息。
步骤S1133,平面化处理经度信息和纬度信息得到无符号初始经度信息整数和无符号初始纬度信息整数。
基于地理特性,经度信息和纬度信息是与球面相符的,也就是说各种经度、纬度是布设于地球所在的球面的,因此,经度信息和纬度信息的数据构成将较为复杂,其包含的信息量也非常多。
平面化处理经度信息和纬度信息,以将对应于球面的经度信息和纬度信息转化为对应于平面的无符号初始经度信息整数和无符号初始纬度信息整数,通过二维球面至一维平面的转换实现经度信息和纬度信息的压缩,该无符号初始经度信息整数和无符号初始纬度信息整数即为压缩所得到的。
具体的,平面化处理过程可通过如下公式实现,即:
Ljo=Ew*108*106+EDEG*6*105+EMINmm*104+EMINF
Lwo=Ns*54*106+NDEG*6*105+NMINmm*104+NMINF
其中,Ljo为无符号初始经度信息整数,Lwo为无符号初始纬度信息整数,Ew为东西经标识;EDEG为经度;EMINmm为经分的整数部分;EMINF为经分的小数部分;NDEG为纬度;NMINmm为纬分的整数部分;NMINF为纬分的小数部分;Ns是南北纬标识。
需要说明的是,有多种信息格式表示不同精度,用于表示经度和纬度的位置信息,以上是采用常用的NMEA格式进行说明,其可根据具体的信息格式进行调整。
步骤1135,通过无符号初始经度信息整数和无符号初始纬度信息整数生成二进制数据的采集信息。
由如上所述的紧缩格式的定义可知,无符号初始经度信息整数和无符号初始纬度信息整数即为紧缩格式的,因此,通过无符号初始经度信息整数和无符号初始纬度信息整数所构成的二进制数据的采集信息也将是紧缩格式的。
二进制数据的采集信息可以是直接由无符号初始经度信息整数和无符号初始纬度信息整数构成,其也可对无符号初始经度信息整数和无符号初始纬度信息整数进行优化压缩后得到,这将根据实际需求灵活确定。
进一步的,在本实施例中,如图4所示,该步骤S1135包括:
步骤S11351,根据所需精度对应的信息压缩宽度对无符号初始经度信息整数和无符号初始纬度信息整数进行精度调整运算,以得到无符号紧缩经度信息整数和无符号紧缩纬度信息整数。
所需精度是进行位置定位所设定的精度,其可用分辨率进行表征,例如,对于一维平面的无符号紧缩经度信息整数和无符号紧缩纬度信息整数而言,其所对应的精度通过一维分辨率表征;对于二维球面的无符号初始经度信息整数和无符号初始纬度信息整数而言,其所对应的精度将通过二维分辨率表征。
基于二进制数据的特征,不同的精度将对应了信息中不同的二进制位数。因此,可根据精度对无符号初始经度信息整数和无符号初始纬度信息整数进行位数缩减。
例如,对于28位的无符号初始经度信息整数和27位的无符号初始纬度信息整数而言,其所对应一维分辨率约0.1852米;而经过如上所述的精度调整运算所得到的24位无符号紧缩经度信息整数和23位无符号紧缩纬度信息整数则对应了约2.9634米的一维分辨率,对应的二维分辨率约4.1909米。
因此,通过这一方式,可对传输的信息进行精度的大小调整,具备了精度的可调性。
具体的,根据无符号初始经度信息整数和无符号初始纬度信息整数,可通过如下公式进行精度调整运算,以得到无符号紧缩经度信息整数和无符号紧缩纬度信息整数,具体公式如下:
Lj=Ljo/2n
Lw=Lwo/2n
其中,Lj为无符号紧缩经度信息整数;Ljo为无符号初始经度信息整数;Lw为无符号紧缩纬度信息整数;Lwo为无符号初始纬度信息整数,参数n的取值则由所需精度和信息压缩宽度进行设置,例如,其可为4。
通过如上所述的过程,在实现精度可调的情况下使得实际应用中只需要要设置合适的精度即可, 而不需要局限于最高精度,进而将得以对无符号初始经度信息整数和无符号初始纬度信息整数实现进一步的压缩,可进一步提高压缩效率,并且得以提升信息传输容量。
步骤11353,由无符号紧缩经度信息整数和无符号紧缩纬度信息整数形成二进制数据的采集信息。
基于此,进一步的,在一个实施例中,采集信息为位置信息,位置信息包含经度信息和纬度信息,存储的基准信息包含基准经度信息和基准纬度信息,步骤S150包括:
将信息差分中经度对应的低位变化部分和纬度对应的低位变化部分按照预设的帧位数拼接后填充到信息子帧里,获得为本次传输的信息子帧,帧位数用于控制信息子帧的长度。
位置信息所包括的经度信息和纬度信息是通过经度和纬度的定位所得到的。
由于信息差分是通过帧的形式进行传输的,每一帧都是用于实现位置信息中有效内容传输的子帧,其数量将根据信息差分的二进制数据位数以及预设的帧位数决定。
信息差分包括了二进制数据的采集信息中经度对应的低位变化部分和纬度对应的低位变化部分。按照预设的帧位数分别对两个低位变化部分中包含的若干位数据进行操作,以得到数量与帧数量相符的信息子帧,该信息子帧中的位数则与预设的帧位数相一致。
这里将以4个信息子帧进行举例说明。在此例子中,信息差分别包括了24位经度所对应的低位变化部分,如24位无符号紧缩经度信息整数,以及23位纬度所对应的低位变化部分,如23位无符号紧缩纬度信息整数。
对于24位无符号紧缩经度信息整数Lj,预设的帧位数为6位,将形成4个均为6位的信息子帧,分别用Lj0、Lj1、Lj2和Lj3表示,并按如下公式计算得到:
Lj0=Lj&0x00003F(即Lj0为Lj的低位0到5位的值)
Lj1=(Lj>>6)&0x00003F(即Lj1为Lj的低位6到11位的值)
Lj2=(Lj>>12)&0x00003F(即Lj2为Lj的低位12到17位的值)
Lj3=(Lj>>18)&0x00003F(即Lj3为Lj的低位18到23位的值)
对于23位无符号紧缩纬度信息整数Lw,一个信息子帧所对应的帧位数为5位,其余均为6位,分别用Lw0、Lw1、Lw2和Lw3表示,并按如下公式计算得到:
Lw0=Lw&0x00003F(即Lw0为Lw的低位0到5位的值)
Lw1=(Lw>>6)&0x00003F(即Lw1为Lw的低位6到11位的值)
Lw2=(Lw>>12)&0x00003F(即Lw2为Lw的低位12到17位的值)
Lw3=(Lw>>18)&0x00001F(即Lw3为Lw的低位18到22位的值)
此外,信息子帧除了包含如上所述计算得到了的数值之外,还包括帧标识,以便于实现后续的传输。
例如,若无符号经度信息整数为1010100001000101001001102,无符号纬度信息整数为100000001110001100011112,相应信息子帧如下表所示:
Figure PCTCN2016090245-appb-000001
表1
通过如上所述的信息子帧生成过程,其也为信息的颗粒化过程,将有效避免了空间的浪费。
上述过程中,对二进制数据的采集信息中低位变化部分,即信息差分进行了拆分和填充,以得到用于传输的信息子帧;而对于差值形式的信息差分而言,其在传输中也将通过拆分和填充的方式得到相应的帧,进而实现传输,其过程将上述与低位变化的信息差分相同。
进一步的,在本实施例中,如图5所示,将信息差分中经度对应的低位变化部分和纬度对应的低位变化部分按照预设的帧位数拼接后填充到信息子帧里,获得为本次传输的信息子帧,帧位数用于控制信息子帧的长度包括:
步骤S151,比对获得的二进制数据的采集信息和存储的基准信息,得到二进制数据的经度信息与基准经度信息相同部分二进制的位数,和二进制数据的纬度信息与所述基准纬度信息相同部分的二进制的位数。
如前所述的,信息差分包括了位置信息中经度对应的低位变化部分和纬度对应的低位变化部位,该低位变化部分是相对存储的基准信息所得到的,并且是二进制数据的形式,其所对应的二进制的位数是位置信息中发生了变化的二进制数据的位数,而剩下的即为位置信息中未发生变化的二进制的位数,即相对基准经度信息和基准纬度信息,经度相同部分的二进制的位数和纬度相同部分的二进制的位数。
步骤S153,根据二进制的位数得到低位变化部分二进制位数的最值,根据最值和预设的帧位数进行传输所需要的帧数量的运算,运算得到的数值是本次传输对应的帧数量。
预先设置了帧位数,以定义信息子帧中二进制数数据的所对应的二进制的位数,进而由此确定了实现位置信息的发送所需要的帧数量。
具体的,按照如下公式对低位变化部分二进制位数的最值和预设的帧位数进行运算即可得到对应的帧数量,即:
N=(Nmax+F-1)/F
其中,N为帧数量,Nmax为低位变化部分二进制位数的最值,帧位数F的取值可为6。
也就是说,预先设置了实现位置信息中有效内容传递的帧位数,根据信息差分得到存储的基准信息和本次传输的二进制数据的位置信息之间经度相关的信息中相同部分的二进制的位数Nj和纬度相关的信息中相同部分的二进制的位数Nw,具体过程如下所述:
存储的基准信息包含基准经度信息Lj1和基准纬度信息Lw1,本次传输中采集信息和存储传输信息均为二进制形式,二进制数据的位置信息中包含了二进制数据的经度信息与基准信息的相同部分Lj和二进制数据的纬度信息与基准信息的相同部分Lw,其也均为二进制的数据形式,则
a)根据信息差分,找出Lj1和Lj的相同部分二进制的位数Nj;
b)根据信息差分,找出Lw1和Lw相同部分二进制的位数Nw;
c)读取经度信息二进制的位数A以及纬度信息二进制的位数B,并分别计算其与对应相同部分二进制的位数之间的差值,并取其中的低位变化部分二进制位数的最值Nmax,即:
取(A-Nj)和(B-Nw)中的最值Nmax。
d)根据该最值Nmax和预设的帧位数F进行传输所需要的帧数量的运算,运算得到的数值即为本次传输中承载信息变化所需要的帧数量,具体公式如下所示:
N=(Nmax+F-1)/F
其中,N为承载信息变化的帧数量,F的取值可为6。
步骤S155,按照预设的帧位数分别将信息差分中经度对应的低位变化部分和纬度对应的低位变化部分拼接后填充到信息子帧里,得到本次传输的与帧数量相符的信息子帧。
可以理解的,如上所述的信息差分可以是由本次传输中相对发生变化的低位所得到的,也可以是相对变化的差值,这两种方式可在实际场景中根据需要组合使用。
在一个实施例中,步骤S130包括:
将获得的二进制数据的采集信息和存储的基准信息逐位进行二进制位的比对,得到获得的二进制数据的采集信息相对存储的基准信息发生变化的部分,该变化部分即为比对得到的信息差分。
或,将获得的二进制数据的采集信息和存储的基准信息进行运算,获得二进制数据的采集信息和存储的基准信息的差值,该差值即为比对得到的信息差分。
对于以差值形式存在的信息差分,可通过下述公式得到:
LjDiff=Lj-Lj1;
LwDiff=Lw-Lw1;
其中,LjDiff为经度对应的差值;Lj为二进制数据的采集信息中的经度信息;Lj1为基准经度信息;
LwDiff为纬度对应的差值;Lw为二进制数据的采集信息中的纬度信息;Lw1为基准纬度信息。
通过如上所述的任意方式,得以运算得到以差值形式存在,或者,以变化部分形式存在的信息差分,进而得到可用于进行传输信息差分,由此实现信息的压缩以及大容量传输。
在一个实施例中,应用信息中采集信息为线性变化信息,信息差分包括获得的二进制数据的采集信息相对存储的基准信息的变化值和变化趋势标识,该步骤S110进一步运算得到线性变化信息和基准的线性变化信息之间紧缩格式的变化信息,该变化信息为获得的二进制数据的采集信息。
如图6所示,该步骤S150包括:
步骤S151b,根据信息差分得到获得的二进制数据的采集信息相对存储的基准信息的变化值和变化趋势标识。
线性变化信息可以采集得到的持续发生线性变化的信息,其可以为速度信息、温度信息、海拔高度信息等,如前所述的,线性变化信息中的传输信息将为变化信息,如速度的变化信息、海拔高度的变化信息,由本次传输所得到的信息差分即为与存储的基准信息进行比对所得到的变化值,此外,还根据本次传输的采集信息和存储的基准信息的比对得到了相应的变化趋势标识,该变化趋势标识用于指示变化值的增或减。
步骤S153b,由变化值和变化趋势标识生成承载线性变化的信息子帧。
通过如上所述过程,基于本次传输中相对基准信息的低位变化部分实现信息压缩,进而大为提高了可进行信息压缩的采集信息种类,极大地扩充了应用场景。
需要说明的是,对于首次进行的信息传输而言,由于并不存在存储的传输信息,也就是说,并不存在参考点,因此,可将存储的基准信息置零。
也就是说,如前所述的,对于线性变化信息而言,是对变化值进行传输,而不会对具体的完整值进行传输,仅仅是通过这一相对值实现完整值的传递,从而不需要浪费空间,保证了压缩效率;对于位置信息而言,其虽然也是通过信息差分实现的信息压缩和传输,但是其仅仅对低位变化部分进行传输,大大减少了传输的数据量,提高了传输的有效性,并且由于所得到的数值是绝对值,极大地避免了位置偏差的出现。
需要说明的是,在如上所述的过程中,对于所进行的采集信息首次传输,其可直接传输完整信息,即二进制数据的采集信息,例如,其可由无符号紧缩经度信息整数和无符号紧缩纬度信息整数,共计47位组成;也可按序传输若干帧数据,例如,若仅对位置信息进行传输则可通过传输若干帧数据实现首次传输。
在一个实施例中,如图7所示,在一个实施例中,一种实现信息压缩的通信方法包括:
步骤S310,接收发送端传输的信息子帧。
如前所述的,在一个实施例中,所得到的信息子帧可由高位至低位的顺序从发送端进行传输以到达接收端,接收得到最低位的信息子帧即可确认接收完毕。
步骤S330,对接收的信息子帧进行恢复得到信息差分,信息差分携带有发送端获得的二进制数据的采集信息相对存储的基准信息的低位变化信息。
步骤S350,根据信息差分和存储的发送端的基准信息还原得到发送端的二进制数据的采集信息。
信息子帧对应了需要进行位拼接的绝对值低位,则将接收的信息子帧全部进行依序拼装等处理得 到信息差分,并在存储的基准信息对该处理得到的数据进行替换,从而恢复得到二进制数据的信息。
若信息子帧对应的信息差分是相对变化的差值,则在由接收的信息子帧得到该差值之后,只由存储的基准信息和该差值之和即可得到当前所接收的二进制数据的采集信息。
对于线性变化信息所对应的信息子帧,由接收的信息子帧提取得到变化值和变化趋势标识,进而以存储的基准信息为参考,恢复得到本次接收得到的线性变化信息。
在另一个实施例中,如上所述的方法还包括:
接收端在接收到发送端发送的完整的二进制数据的采集信息时,将存储的发送端的基准信息更新为完整的二进制数据的采集信息,并向发送端发送传输成功确认。
或,在接收端从信息子帧获得采集信息到达边界指示后,将存储的发送端的基准信息更新为还原获得的二进制数据的采集信息,并向发送端发送传输成功确认。
或,接收端在判定还原获得的二进制数据的采集信息与存储的发送端的基准信息相比,变化达到预设的边界值时,将存储的发送端的基准信息更新为还原获得的二进制数据的采集信息,并向发送端发送传输成功的确认。
对于接收端所接收的二进制数据的采集信息是否为完整的二进制数据采集信息的判断,可以由接收端执行,也可以是发送端在自身发送的消息里直接指示所携带的采集信息为完整的二进制数据的采集信息,进而接收端在接收到该指示后直接保存接收到的采集信息。
在接收端中,与发送端相对应的,为保证高效率压缩,以满足需要很高效率压缩的场景,本申请在接收端提供了如下两种实施方式进行基准信息的更新。
一方面,接收端为发送端预设相应的时间周期,以定时更新基准信息,在预设时间周期到达时,使用接收端当前获得的发送端的二进制数据的采集信息更新自身为此发送端存储的基准信息,进而相对于新的基准信息进行后续的还原。
需要说明的是,如前所述的,发送端也预设了相同的时间周期。
另一方面,接收端也设置了发送端的边界值,接收端当前获得的二进制数据的采集信息在相对存储的基准信息达到边界值,则需要进行存储的基准信息的更新,以保持数据压缩的高效性。
与前述相类似的,发送端也预设了相同的边界值。
进一步的,对于接收端的更新方法,与发送端相对应的,本申请提供了三种不同的更新方法。
第一种:
接收端接收发送端发送的完整的二进制数据的采集信息;
接收端在接收到发送端发送的完整的二进制数据的采集信息时,将存储的发送端的基准信息更新为完整的二进制数据的采集信息,并向发送端发送传输成功确认。
第二种:
接收端接收发送端发送的信息子帧,此时通过信息子帧恢复得到信息差分,并根据信息差分和存储的基准信息还原来获得二进制数据的采集信息;
接收端在判还原获得的二进制数据的采集信息与存储的发送端的基准信息相比,变化达到预设的边界值时,将存储的发送端的基准信息更新为还原获得的二进制数据的采集信息,并向发送端发送传输成功的确认。
第三种:
接收端接收发送端发送的信息子帧,且信息子帧中携带有采集信息到达边界指示;
在接收端从信息子帧获得采集信息到达边界指示后,将存储的发送端的基准信息更新为还原获得的二进制数据的采集信息,并向发送端发送传输成功确认。
通过上述任意一种实施方式都能够完成接收端中存储的发送端的基准信息的更新,并向发送端发送传输成功确认,以继续进行其与发送端之间携带信息差分的信息子帧的传输。
需要说明的是,接收端由此所还原获得的二进制数据的采集信息可以是位置信息,也可以是线性变化信息。
需要特别说明的是,二进制数据的采集信息和存储的基准信息为紧缩格式的二进制数据。
进一步的,在本实施例中,如图8所示,该步骤S330包括:
步骤S331,拼装接收的信息子帧得到信息差分。
在进行信息的还原中,首先对接收的信息子帧进行拼装,以得到紧缩格式的信息差分。其中,相对应的,由此拼装得到的信息差分可为无符号紧缩经度信息整数和无符号紧缩纬度信息整数。例如,对于位数为6的信息子帧拼装过程可如以下公式所示:
Lj=Lj0|(Lj1<<6)|(Lj2<<12)|(Lj3<<18)
Lw=Lw0|(Lw1<<6)|(Lw2<<12)|(Lw3<<18)
步骤S333,根据信息差分以存储的基准信息为参考进行还原得到二进制数据的采集。
对于作为位置信息的采集信息而言,所得到的二进制数据的采集信息将最终进行球面化处理,进而得到应用信息中包含的采集信息。
接收端中,该采集信息信息是为一维平面形式的,需将其还原为二维球面形式,以得到作为发送端的通信设备所发送的位置信息。
具体的,与作为发送端的通信设备中其所进行的平面化处理相对应的,通过球面化处理转化得到初始的采集信息,即位置信息。
例如,得到初始的位置信息的详细过程如下述公式所示:
Ljo小于108*106时Ew等于0,否则Ew等于1
EDEG=Ljo%(108*106)/(6*105)
EMINmm=Ljo%(108*106)/(104)
EMINF=Ljo%104
Lwo小于54*106时Ns等于0,否则Ns等于1
NDEG=Lwo%(54*106)/(6*105)
NMINmm=Lwo%(54*106)/(104)
NMINF=Lwo%104
其中,Ljo为二进制数据的采集信息中经度信息,例如,无符号初始经度信息整数;Lwo为二进制数据的采集信息中的纬度信息,例如,无符号初始纬度信息整数;Ew为东西经标识;EDEG为经度;EMINmm为经分的整数部分;EMINF为经分的小数部分;NDEG为纬度;NMINmm为纬分的整数部分;NMINF为纬分的小数部分;Ns是南北纬标识。
通过如上所述的过程,将无符号初始经度信息整数和无符号初始纬度信息整数还原为初始的位置信息。进一步的,在本实施例中,接收端接收传输的信息子帧,承载本次传输中绝对低位发生变化的数据,则该步骤S333包括:在接收端存储的基准信息中在绝对低位替换对应数据为信息差分,替换后完整信息对应的数值即为恢复的二进制数据的采集信息信息。
进一步的,在另一个实施例中,采集信息为位置信息,位置信息包含经度信息和纬度信息,发送端的基准信息包含基准经度信息和基准纬度信息,则如图9所示,该步骤S330包括:
步骤S3311,由接收的信息子帧得到每一信息子帧中经度对应的二进制数据和纬度对应的二进制数据。
传输信息的接收将使得接收端接收得到与发送端确定的帧数量相符的若干个信息子帧。
步骤S3313,根据信息子帧中的帧标识拼装每一信息子帧中经度对应的二进制数据,以得到经度对应的低位变化部分,根据信息子帧中的帧标识拼装每一信息子帧中纬度对应的二进制数据,以得到纬度对应的低位变化部分。
由每一信息子帧得到经度对应的二进制数据和纬度对应的二进制数据,因此,将由若干个每一信息子帧所得到的若干个经度对应的二进制数据拼装在一起即可得到发送端在本次传输中发送的经度对应的变化部分;与之相对应的,将由若干个每一信息子帧所得到的若干个纬度对应的二进制数据拼装在一起即可得到发送端发送的本次传输中纬度对应的变化部分。
步骤S3315,拼装得到的经度对应的低位变化部分和纬度对应的低位变化部分构成信息差分。
与发送端所运算得到的信息差分过程相逆的,例如,若采集信息为位置信息,则接收得到经度和纬度对应的差值,此差值与读取的基准信息之和即可得到采集信息。
具体的,将计算经度对应的差值和读取的基准信息中经度相关的信息之和,所得到的二进制数值即为恢复的采集信息中经度相关的信息;
对应的,计算纬度对应的差值和读取的基准信息中纬度相关的信息之和,所得到的二进制数据即为恢复的采集信息中纬度相关的信息。
所对应的详细计算公式如下所示:
Lj=Lj1+LjDiff;
Lw=Lw1+LwDiff;
其中,Lj为恢复的采集信息中经度相关的信息;Lj1为读取的基准信息中经度相关的信息;LjDiff为经度对应的差值;
Lw为恢复的采集信息中纬度相关的信息;Lw1为读取的基准信息中纬度相关的信息;LwDiff为纬度相关的差值。
在一个实施例中,步骤S350包括:
接收端将存储的发送端的基准信息的绝对低位的数据替换为信息差分,替换后获得的数据即为二进制数据的采集信息。
或,将信息差分和存储的发送端的基准信息进行运算,得到信息差分和存储的发送端的基准信息之和,获得的数据即为发送端的二进制数据的采集信息。
通过如上所述的过程,将使得接收端中能够通过信息差分快速进行恢复,进而保证了信息压缩过程中的处理效率。
在另一个实施例中,采集信息为线性变化信息,如图10所示,上述对接收的信息子帧进行恢复得到信息差分,根据信息差分和存储的发送端的基准信息还原得到发送端的二进制数据的采集信息包括:
步骤S501,根据信息子帧中的帧标识拼装接收的信息子帧得到相对存储的基准信息的变化值和变化趋势标识,变化值和变化趋势标识即为信息差分。
对于速度信息、海拔高度信息等线性变化信息而言,接收端在接收得到若干信息子帧时,直接根据帧标识对其进行拼装,相对基准信息的变化值和变化趋势标识。
步骤S503,根据变化趋势标识对变化值和存储的基准信息进行运算,以得到发送端的二进制数据的采集信息。
在另一个实施例中,如上所述的得到二进制数据的采集信息之后,该方法还包括:
根据所需精度对应的信息压缩宽度对二进制数据的采集信息进行精度还原运算得到还原了精度的采集信息。
与前述相对应的,二进制数据的采集信息包括了无符号紧缩经度信息整数和无符号紧缩纬度信息整数,因此,将对其根据精度和信息压缩宽度对其进行还原,以得到还原了原始精度的采集信息,该采集信息包括无符号初始经度信息整数和无符号初始纬度信息整数。
接收端通过这一方式,将使得紧缩格式的采集信息得到还原出来,以便于后续球面化处理后输出完整的位置信息,进而实现通信应用的各种功能。
通过如上所述的过程,对于运行于通信设备中的各种通信应用可进行各种采集信息的传输,并且保证了传输效率和压缩效率,有效提升了信息传输容量。
需要说明的是,如上所述的过程适用于全球定位信息的传输,该全球定位信息的初始格式可为NMEA格式,也可以是其它的一些格式,对此不进行限定。
通过如上所述的过程,使得进行信息传输的承载空间是动态可变的,而避免了固定完整的信息传 输,从而将极大地提高信息压缩效率,避免造成空间的浪费。
下面结合一个具体的实施来详细阐述本发明的方法。该实施例中,下述表2、表3和表4示出了作为发送端的通信设备需要按序发送的位置信息,即第一次位置信息、第二次位置信息和第三次位置信息。

第三次位置信息
表4
其中,该第一次位置信息是初次传输的信息,第二位置信息是第二次传输的信息,而第三位置信息则是第三次传输的信息。
1)作为发送端的通信设备将初始的位置信息转化为紧缩格式,即对位置信息进行平面化处理后根据精度进行运算,即可得到紧缩格式的位置信息,具体如下述公式所述:
第一次位置信息:
Lj=Ljo/24=(Ew*108*106+EDEG*6*105+EMINmm*104+EMINF)/24
=(1*108*106+114*6*105+4*104+4000)/24=11027750=0xA84526
Lw=Lwo/24=(1*54*106+22*6*105+37*104+4000)/24=4223375=0x40718F
第二次位置信息:
Lj=Ljo/24=(Ew*108*106+EDEG*6*105+EMINmm*104+EMINF)/24
=(1*108*106+114*6*105+4*104+6000)/24=11027875=0xA845A3
Lw=Lwo/24=(1*54*106+22*6*105+37*104+2000)/24=4223250=0x407112
第三次位置信息:
Lj=Ljo/24=(Ew*108*106+EDEG*6*105+EMINmm*104+EMINF)/24
=(1*108*106+114*6*105+4*104+6450)/24=11027903=0xA845BF
Lw=Lwo/24=(1*54*106+22*6*105+37*104+1750)/24=4223234=0x407102
通过上述运算,将分别得到共计47位的无符号紧缩经度信息整数和无符号紧缩纬度信息整数。
2)对于第一次位置信息所对应的初次发送,由于当前存储的上一传输信息为空,则按下述47位的4个信息子帧发送相关完整的经纬信息,即
Nj=24,(24-Nj)=24
Nw=23,(23-Nw)=23
Nmax=24
N=(Nmax+5)/6=4
其中,在此公式N=(Nmax+F-1)/F中,预设的帧位数F的取值为6。
由此将分别运算得到第一次传输所对应的信息子帧,即
a)最低位的信息子帧运算:
Njw=002
Lj0=Lj&0x00003F=0xA84526&0x00003F=0110102
Lw0=Lw&0x00003F=0x40718F&0x00003F=0011112
所形成的信息子帧为00100110001111;
b)次低位的信息子帧运算:
Njw=012
Lj1=(Lj>>6)&0x00003F=(0xA84526>>6)&0x00003F=0101002
Lw1=(Lw>>6)&0x00003F=(0x40718F>>6)&0x00003F=0001102
所形成的信息子帧为010100000110;
c)次高位的信息子帧运算:
Njw=102
Lj2=(Lj>>12)&0x00003F=(0xA84526>>12)&0x00003F=0001002
Lw2=(Lw>>12)&0x00003F=(0x40718F>>12)&0x00003F=0001112
所形成的信息子帧为000100000111;
d)最高位的信息子帧运算:
Njw=112
Lj3=(Lj>>18)&0x00003F=(0xA84526>>18)&0x00003F=1010102
Lw3=(Lw>>18)&0x00003F=(0x40718F>>18)&0x00001F=100002
所形成的信息子帧为10101010000。
其中,Njw为信息子帧中的帧标识,将按照帧标识顺序发送信息子帧。
3)以紧缩格式存储发送的第一次发送的信息,将第一次位置信息所对应的Lj=11027750=0xA84526和Lw=4223375=0x40718F存储为上一次发送的位置信息。
4)第二次位置信息的发送中,Lj=11027875=00xA845A3、Lw=4223250=0x407112,
Nj=16,(24-Nj)=8
Nw=15,(23-Nw)=8
Nmax=8
N=(8+5)/6=2
故,只需要发送如下2个低位的信息子帧;
a)最低位的信息子帧运算
Njw=002
Lj0=Lj&0x00003F=00xA845A3&0x00003F=1000112
Lw0=Lw&0x00003F=0x407112&0x00003F=0100102
所形成的信息子帧为00010110010010;
b)次低位的信息子帧运算

所形成的信息子帧为010110000100。
在此第二次位置信息的发送中,也可通过如下过程进行运算:
LjDiff=Lj-Ljl=0xA845A3-0xA84526=0x7d=125=0000011111012
LwDiff=Lw-Lwl=0x407112-0x40718F=-0x7d=-125=1000011111012
Nmax=7,N=2
由LjDiff低6位和LwDiff低6位组成最低位的信息子帧如下:
LjDiff0=Lj-Ljl=0xA845A3-0xA84526=0x7d=125=1111012
LwDiff0=Lw-Lwl=0x407112-0x40718F=-0x7d=-125=1111012
所形成的信息子帧为00111101111101;
由LjDiff高6位和LwDiff高6位组成次低位的信息子帧如下:
LjDiff1=Lj-Ljl=0xA845A3-0xA84526=0x7d=125=0000012
LwDiff1=Lw-Lwl=0x407112-0x40718F=-0x7d=-125=1000012
所形成的信息子帧为01000001100001。
5)第三次位置信息的发送中,Lj==11027903=0xA845BF、Lw==4223234=0x407102。
Nj=19,(24-Nj)=5
Nw=18,(23-Nw)=5
Nmax=5
N=(5+5)/6=1
故,只需要发送如下1个低位的信息子帧:
a)最低位的信息子帧运算
Njw=002
Lj0=Lj&0x00003F=0xA845BF&0x00003F=1111112
Lw0=Lw&0x00003F=0x407102&0x00003F=0000102
所形成的信息子帧为00111111000010。
在此第三次位置信息的发送中,信息差分也可为相对变化的差值,即通过帧的形式传输,因此也可通过如下过程进行运算:
LjDiff=Lj-Ljl=0xA845BF-0xA845A3=0x1C=0111002
LwDiff=Lw-Lwl=0x407102-0x407112=-0x10=1100002
Nmax=6,N=1
由LjDiff低6位和LwDiff低6位组成最低位的信息子帧如下:
LjDiff0=Lj-Ljl=0xA845BF-0xA845A3=0x1C=0111002
LwDiff0=Lw-Lwl=0x407102-0x407112=-0x10=1100002
所形成的信息子帧为00011100110000;
6)接收端第一次接收到发送端以信息子帧形式发送的位置信息时,
Lj0=0110102,Lw0=0011112
Lj1=0101002,Lw1=0001102
Lj2=0001002,Lw2=0001112
Lj3=1010102,Lw3=100002
按照如下公式实现进行恢复计算,以得至位置信息Lj和Lw,
Lj=Lj0|(Lj1<<6)|(Lj2<<12)|(Lj3<<18)=11027750=0xA84526
Lw=Lw0|(Lw1<<6)|(Lw2<<12)|(Lw3<<18)=4223375=0x40718F
并保存为该发送端上一次接收的基准信息Ljl和Lwl。
7)接收端第二次接收得到2个信息子帧时,一方面所接收得到的信息子帧和进行的恢复计算如下:
Lj0=1000112,Lw0=0100102
Lj1=0101102,Lw1=0001002
Ljl=11027750=0xA84526
Lwl=4223375=0x40718F
使用Lj0、Lw0、Lj1和Lw1替换上一次接收的基准信息Ljl和Lwl中的对应内容还原为紧格式的位置信息,即Lj=11027875=00xA845A3、Lw=4223250=0x407112,并存储为上一次接收的基准信息Ljl和Lwl。
另一方面,所接收得到的信息子帧中经度对应的二进制数值和纬度对应的二进制数值如下:
LjDiff0=Lj-Ljl=0xA845A3-0xA84526=0x7d=125=1111012
LwDiff0=Lw-Lwl=0x407112-0x40718F=-0x7d=-125=1111012
LjDiff1=Lj-Ljl=0xA845A3-0xA84526=0x7d=125=0000012
LwDiff1=Lw-Lwl=0x407112-0x40718F=-0x7d=-125=1000012
由此拼装接收得到的信息子帧得到信息差分,即经度对应的差值LjDiff和纬度对应的差值LwDiff:
LjDiff=LjDiff1&LjDiff0=0000011111012=0x7d
LwDiff=LwDiff1&LjDiff0=0000011111012=-0x7d
进行恢复运算,即:
Lj=LjDiff+Ljl=0x7d+0xA84526=0xA845A3
Lw=LwDiff+Lwl=-0x7d+0x40718F=0x407112
用LjDiff0、LwDiff0、LjDiff1、LwDiff1和上次位置信息中的Ljl、Lwl按上述公式计算位置信息Lj=11027875=00xA845A3、Lw=4223250=0x407112。并保存为该发送端上一次接收得到的基准信息Ljl和Lwl。
8)接收端第三次接收得到1个信息子帧时,一方面所接收得到的信息子帧和进行的恢复计算如下:
Lj0=1111112,Lw0=0000102
Ljl=11027875=00xA845A3
Lwl=4223250=0x407112
使用Lj0和Lw0替换上一次接收的基准信息,Ljl和Lwl中的对应内容还原为紧格式的位置信息,即Lj=11027903=0xA845BF、Lw=4223234=0x407102,并存储为上一次接收的基准信息Ljl和Lwl。
另一方面,所接收得到的信息子帧中经度对应的二进制数值和纬度对应的二进制数值如下:
LjDiff0=Lj-Ljl=0xA845BF-0xA845A3=0x1C=0111002
LwDiff0=Lw-Lwl=0x407102-0x407112=-0x10=1100002
由此拼装接收得到的信息子帧得到信息差分,即经度对应的差值LjDiff和纬度对应的差值LwDiff:
LjDiff=LjDiff0
LwDiff=LwDiff0
进行恢复运算,即:
Lj=LjDiff+Ljl=0x1C+0xA845A3=0xA845BF
Lw=LwDiff+Lwl=-0x10+0x407112=0x407102
用LjDiff0、LwDiff0和基准信息中的Ljl、Lwl按上述公式计算位置信息Lj=0xA845BF、Lw=0x407102。并保存为该发送端基准信息Ljl和Lwl。
9)接收端通过如下公式对二进制数据的采集信息,即位置信息进行球面化处理以及精度还原运算,以实现恢复计算。

通过对比可得知,第三次位置信息中纬度还原误差为0.0006纬分,约1.1米,经度还原误差为0.0002经分,约0.4米。
下面以采集信息为线性变化信息为例来说明本发明的方案,其中:
一应用场景中,该线性变化信息为速度信息,在其所进行的首次传输中,上一传输信息为静止速度,通过二进制数据的采集信息与静止速度的变化部分,即变化信息实现信息压缩,以传输得到的信息子帧。
在此信息子帧中,最高位为变化趋势标识,用于指示速度的增减,例如,1表示减少,0表示增加。随后n位则指示了速度变化值,所使用的帧位数是根据所需的精度和范围进行选择的,例如,其可为6。
由此可知,本次传输将以7个位的信息子帧的形式进行传输,并且后续传输中以基准信息为参考进行传输。
与之相对应的,接收端将以基准信息为参考对接收的信息子帧进行恢复计算,以还原得到应用信息包含的速度信息。
另一应用场景中,该线性变化信息也为速度信息,则在其所进行的首次传输中,发送端包含变化值ef、变化趋势标识为0x,即增加的低位帧0xef,接收端将以静止为参考运算得到接收端当前时速为64公里/每小时。
发送端第二次发送变化值8f,变化趋势标识为0x,即减少的低位帧0x8f,该变化值是以64公里/每小时为参考指示速度减少的,其所对应的时速为39公里/每小时。
接收端第二次接收到该信息子帧时,将以65公里/每小时为参考,根据变化值和变化趋势标识恢复得到当前时速为39公里/每小时。
另一应用场景中,该线性变化信息为海拔高度信息,所对应的信息子帧中变化趋势标识指示了海拔高度相对参考点的变化,即增或减,其中,1为减少,0为增加。以n位二进制数值指示海拔高度变化,n的取值可根据精度和压缩数据宽度进行选择,下面以n=14,单位为米进行说明。
在其所进行的首次传输中,上一传输信息为海拔1000米。
另一应用场景中,该线性变化信息也为海拔高度信息,若发送端发送低位帧0x32,则说明当前发送端以海拔高度1000米为参考增加50米。
相对应的,接收端接收到该信息帧后,通过恢复计算即可得获知发送端当前所在海拔高度为1050米。
在一个实施例中,还提供了一种实现信息压缩的通信装置,如图11所示,包括:
步骤S610,提取应用信息中的采集信息,将所述采集信息进行转换,获得二进制数据的采集信息。
如前所述的,应用信息是通信设备中任一通信应用所产生的,以用于提供当前所对应的状态,如,位置、移动状态等,可用于输出所在位置、速度、海拔高度等信息,具体输出的信息根据具体运营的需要配置。采集信息将是对当前所对应的状态进行采集所得到的,如,位置采集、速度采集、海拔高度采集等。
不同的采集信息均有其特定的信息格式,并且根据定义的信息格式还包含了其它的一些信息,为了保证信息的有效性,在应用信息中提取得到采集信息之后,将其转换成为二进制数据的形式,进而屏蔽无用信息,减少冗余数据,提高压缩处理的针对性和有效性。
其中,根据采集信息的不同,其所进行的转换也将各不相同,例如,如果采集信息是位置信息,则所进行的转换过程为格式转化。
需要说明的是,通信设备之间进行通信所定义的信息格式是无符号的二进制形式,因此,预处理得到的二进制数据的采集信息也必将是无符号的二进制形式的。
一方面,采集信息是位置信息,该位置信息完整表示了当前所在的地理位置;另一方面,采集信息是速度信息、海拔高度信息等线性变化信息时,则在对提取的采集信息进行转换的过程中,将首先对其进行变化信息的运算,对获得的变化信息进行格式转化,进而得到二进制数据的采集信息。
步骤S630,在二进制数据的采集信息中提取低位部分的二进制数据。
如前所述的,二进制数据的采集信息即为由应用信息中提取的采集信息转换所得到的二进制数据。可以理解的,此二进制数据包括高位部分的二进制数据和低位部分的二进制数据,其中,高位部分和低位部分在此二进制数据中的分界可根据实际运营的情况进行配置。
作为发送端的通信设备进行采集信息的传输中,直接对转换所得到的二进制数据进行低位部分的提取,获得低位部分的二进制数据。
步骤S650,填充低位部分的二进制数据至信息子帧里,获得本次传输的信息子帧。
使用低位部分的二进制数据进行帧的填充,以将其填充至信息子帧里,由此获得的信息子帧承载了持续进行的信息采集中发生的信息变化。通过获得的信息子帧,使得低位部分的二进制数据能够通过一个或者多个帧的形式传输出去。
步骤S670,传输获得的信息子帧。
获得承载信息变化的信息子帧之后,将其传输至相应的接收端。接收端在接收到发送端向其传输的信息子帧,并通过对信息子帧中填充的二进制数据进行顺序拼装即可得到本次传输的采集信息中低位部分的二进制数据。
在优选的实施例中,发送端中信息子帧的传输将是按序进行的,例如,根据其对应于采集信息中的顺序进行传输,以保证接收端中接收和处理的有序性。
发送端中采集信息的传输仅与二进制数据的采集信息中低位部分的二进制数据相关,而并不需要对高位部分的二进制数据进行传输,由此,对于发送端和接收端之间频繁的数据传输而言,将大为降低了传输的数据量,进而提高了可传输容量,由此也将得到很高的压缩率,实现高效率压缩。
另外,发送端中传输的实现只需要直接提取二进制数据和填充数据即可,过程简单,易于实现,由此将使得无论何种硬件条件的通信设备,即任意通信设备都能够采集如上所述的过程实现传输,进而使得如上所述的过程在具体实现中不受限制,且能够保证高压缩率。
通过将如上所述的过程应用于通信设备,使得应用信息中采集信息相关内容的传递不需要对整个采集信息进行传输,提高了传输效率,避免传输过程中的控制信道拥塞。
在此需要说明的是,二进制数据的采集信息及存储的基准信息均为紧缩格式的二进制数据。
因此,在此基础上,在上述采集信息的转换包括了紧缩格式的转化,以适应于信息的传输。其中,如果采集信息是位置信息,则紧缩格式的转化包括平面化处理位置信息中经度信息和纬度信息的过程,以及精度调整运算的过程。
由位置信息中获取得到经度信息和纬度信息,并分别将经度信息和纬度信息转化为紧缩格式,以形成紧缩格式的位置信息,即二进制数据的采集信息。
紧缩格式指的是无符号整数的数据形式,也就是说,分别将获取得到的经度信息和纬度信息转化为无符号整数的数据形式,进而由转化得到的一串无符号整数形成本次传输信息。
通过紧缩格式的转化,将对位置信息进行了优化压缩,从而有效地摈弃了无用信息,提高了后续信息传递的有效性,有助于提升位置信息传输容量。
需要说明的是,由于应用信息中可包含了多种采集信息,因此,除了位置信息之外,采集信息还可为线性变化信息,例如,速度信息、海拔高度信息,对于此类采集信息,其所进行的转换过程为:运算线性变化信息和上一采集的线性变化信息之间紧缩格式的变化信息,该变化信息即为二进制数据的采集信息。
与位置信息的复杂程度所不同的是,在应用信息中,该线性变化信息本身即为紧缩格式的,因此,并不需要进行紧缩格式转化,而只需要获取两个线性变化信息之间发生的变化,即变化信息。
进一步的,在本实施例中,所涉及的平面化处理过程包括:由位置信息得到经度信息和纬度信息,平面化处理经度信息和纬度信息得到无符号初始经度信息整数和无符号初始纬度信息整数,通过无符号初始经度信息整数和无符号初始纬度信息整数生成二进制数据的采集信息。
基于地理特性,经度信息和纬度信息是与球面相符的,也就是说各种经度、纬度是布设于地球所在的球面的,因此,经度信息和纬度信息的数据构成将较为复杂,其包含的信息量也非常多。
平面化处理经度信息和纬度信息,以将对应于球面的经度信息和纬度信息转化为对应于平面的无符号初始经度信息整数和无符号初始纬度信息整数,通过二维球面至一维平面的转换实现经度信息和纬度信息的压缩,该无符号初始经度信息整数和无符号初始纬度信息整数即为压缩所得到的。
具体的,平面化处理过程可通过如下公式实现,即:
Ljo=Ew*108*106+EDEG*6*105+EMINmm*104+EMINF
Lwo=Ns*54*106+NDEG*6*105+NMINmm*104+NMINF
其中,Ljo为无符号初始经度信息整数,Lwo为无符号初始纬度信息整数,Ew为东西经标识;EDEG为经度;EMINmm为经分的整数部分;EMINF为经分的小数部分;NDEG为纬度;NMINmm为纬分的整数部分;NMINF为纬分的小数部分;Ns是南北纬标识。
需要说明的是,有多种信息格式表示不同精度,用于表示经度和纬度的位置信息,以上是采用常用的NMEA格式进行说明,其可根据具体的信息格式进行调整。
由如上所述的紧缩格式的定义可知,无符号初始经度信息整数和无符号初始纬度信息整数即为紧缩格式的,因此,通过无符号初始经度信息整数和无符号初始纬度信息整数所构成的二进制数据的采集信息也将是紧缩格式的。
二进制数据的采集信息可以是直接由无符号初始经度信息整数和无符号初始纬度信息整数构成,其也可对无符号初始经度信息整数和无符号初始纬度信息整数进行优化压缩后得到,这将根据实际需求灵活确定。
进一步的,在本实施例中,通过无符号初始经度信息整数和无符号初始纬度信息整数生成二进制数据的采集信息的过程包括:
(1)根据所需精度对应的信息压缩宽度对无符号初始经度信息整数和无符号初始纬度信息整数进行精度调整运算,以得到无符号紧缩经度信息整数和无符号紧缩纬度信息整数。
(2)由无符号紧缩经度信息整数和无符号紧缩纬度信息整数形成二进制数据的采集信息。
所需精度是进行位置定位所设定的精度,其可用分辨率进行表征,例如,对于一维平面的无符号紧缩经度信息整数和无符号紧缩纬度信息整数而言,其所对应的精度通过一维分辨率表征;对于二维球面的无符号初始经度信息整数和无符号初始纬度信息整数而言,其所对应的精度将通过二维分辨率表征。
基于二进制数据的特征,不同的精度将对应了信息中不同的二进制位数。因此,可根据精度对无符号初始经度信息整数和无符号初始纬度信息整数进行位数缩减。
例如,对于28位的无符号初始经度信息整数和27位的无符号初始纬度信息整数而言,其所对应一维分辨率约0.1852米;而经过如上所述的精度调整运算所得到的24位无符号紧缩经度信息整数和23位无符号紧缩纬度信息整数则对应了约2.9634米的一维分辨率,对应的二维分辨率约4.1909米。
因此,通过这一方式,可对传输的信息进行精度的大小调整,具备了精度的可调性。
具体的,根据无符号初始经度信息整数和无符号初始纬度信息整数,可通过如下公式进行精度调整运算,以得到无符号紧缩经度信息整数和无符号紧缩纬度信息整数,具体公式如下:
Lj=Ljo/2n
Lw=Lwo/2n
其中,Lj为无符号紧缩经度信息整数;Ljo为无符号初始经度信息整数;Lw为无符号紧缩纬度信息整数;Lwo为无符号初始纬度信息整数,参数n的取值则由所需精度和信息压缩宽度进行设置,例如,其可为4。
通过如上所述的过程,在实现精度可调的情况下使得实际应用中只需要要设置合适的精度即可,而不需要局限于最高精度,进而将得以对无符号初始经度信息整数和无符号初始纬度信息整数实现进一步的压缩,可进一步提高压缩效率,并且得以提升信息传输容量。
在一个实施例中,步骤S670之前,如图12所示,如上所述的方法还包括:
步骤S710,在二进制数据的采集信息中提取高位部分的二进制数据,并存储为自身的基准信息。
发送端获得的二进制数据的采集信息中,如前所述的,低位部分的二进制数据将被传输至接收端。而在信息的采集和传输中,由于是持续进行的,在一定范围内信息之间的变化较小,即仅限于低位部分,而高位部分的二进制数据是在此范围内保持不变的,因此,可根据高位部分的二进制数据配置发送端自身的基准信息。
发送端中,可将高位部分的二进制数据直接存储为基准信息,也可将高位部分的二进制数据作为基准信息的高位部分,基准信息的低位部分则使用区别于高位部分的二进制数据进行填充,具体按约定即可,例如,可将基准信息的低位部分全部以0填充,由此获得发送端自身的基准信息,并存储。
可以理解的,对于接收端,其必将进行发送端的基准信息的存储,以用于还原得到发送端的二进制数据的采集信息,而随着每次传输中采集信息的不断发生变化,相对原有的基准信息,即接收端存在的发送端的基准信息,二进制数据的采集信息的变化将不再仅限于低位部分,其高位部分也发生了变化,因此,为保证准确性,此时需要进行基准信息的更新。
由此可知,发送端中存储的自身的基准信息用于评估是否需要对其在接收端所存储的基准信息进行更新,以保障后续得以继续进行信息子帧的传输。
步骤S730,向信息子帧的接收端传输高位部分的二进制数据,高位部分的二进制数据的传输用于在接收端进行基准信息的存储。
在发送端进行信息子帧的传输,以将二进制数据的采集信息中低位部分的二进制数据传递至接收端之前,需要先向接收端进行高位部分的二进制数据的传输,以便于接收端在接收到发送端的信息子帧时能够还原得到发送端的二进制数据的采集信息。
接收端中为发送端所进行的基准信息存储与发送端所进行的自身的基准信息存储中,所使用的高位部分的二进制数据相一致。
在优选的实施例中,发送端所进行的高位部分的二进制数据传输将是有确认的传输,在高位部分的二进制数据的成功传输之后接收端向发送端发送传输成功确认,以过两端之间高位部分二进制数据的可靠性传输,来保证两端存储的高位部分的二进制数据的一致性。
通过上述过程,使得发送端在向接收端传输信息子帧之前,首先在接收端中存储发送端的基准信息,由此保障发送端能够通过信息子帧承载并传输信息变化,进而也保障了接收端获得二进制数据的采集信息的准确性。
在一个实施例中,如图13所示,如上所述的方法还包括:
步骤S810,在获得二进制数据的采集信息之后,判断二进制数据的采集信息中高位部分的二进制数据相对于存储的自身的基准信息是否存在变化,若为是,则执行步骤S830,若为否,则执行步骤S670。
接收端获得二进制数据的采集信息,并相对存储的自身的基准信息,进行高位部分的比对,以判断二进制数据的采集信息中高位部分的二进制数据是否发生了变化,若为是,则说明二进制数据的采集信息变化较大,需要对原有的基准信息进行更新,以存储新的基准信息。
如果相对存储的自身的基准信息进行高位部分比对所得到的判断结果指示了二进制数据的采集信息中高位部分不存在变化,是与存储的自身的基准信息相一致的,则继续进行信息子帧的传输。
步骤S830,在信息子帧的传输之前,传输高位部分的二进制数据,并在接收到接收端的传输成功的确认之后,再进行信息子帧的传输。
二进制数据的采集信息发生了高位部分二进制数据的变化时,向信息子帧的接收端传输高位部分的二进制数据,以向接收端更新存储的发送端的基准信息。
接收端在完成发送端的基准信息更新和向接收端所进行的传输成功的确认之后,发送端方可进行信息子帧的传输,由此将保证了基准信息的及时更新,并使得远端的接收端能够适应于采集信息的变化,提高了发送端和接收端之间信息传输的自适应程度。
需要说明的是,在发送端的基准信息更新中,接收到发送端传输的高位部分的二进制数据的接收端将涉及到发送端的基准信息更新和向发送端所进行的传输成功的确认,这两个执行过程可不限定于先后顺序,对于发送端而言,只要接收端完成这两个执行过程即可继续进行信息子帧的传输;对于接收端而言,只要完成这两个执行过程即可进行发送端的二进制数据的采集信息的还原。
进一步的,在本实施例中,采集信息为位置信息,位置信息包含经度信息和纬度信息,存储的基准信息包括基准经度信息和基准纬度信息,则步骤S810所执行的二进制数据的采集信息中高位部分的二进制数据相对于存储的自身的基准信息之间是否存在变化的判断包括:
对经度信息和存储的自身的基准经度信息、纬度信息和存储的自身的基准纬度信息进行二进制数据比对,判断经度信息和基准经度信息之间、纬度信息和基准纬度信息之间是否存在高位部分的变化,以得到高位部分是否变化的判断结果。
相对应的,位置信息、位置信息中的经度信息和纬度信息、基准信息中的基准经度信息和基准纬度信息均为二进制数据,因此,都存在着高位部分的二进制数据和低位部分的二进制数据。
基于比对于对应性,将在经度信息和基准经度信息之间、纬度信息和基准纬度信息之间进行比对,以判断经度信息和基准经度信息之间是否存在高位部分的变化,纬度信息和基准纬度信息之间之间是否存在高位部分的变化,任意一高位部分变化的存在都得到高位部分发生变化的判断结果。
如果经度信息和基准经度信息之间高位部分不存在变化,并且纬度信息和基准纬度信息之间高位 部分也不存在变化,则得到高位部分未发生变化的判断结果。
需要说明的是,具体实现中,信息之间的比对和变化的判断可以是通过直接进行二进制数据的逐位比对过程。
在一个实施例中,如上所述的方法还包括:
在获得二进制数据的采集信息,且判断二进制数据的采集信息中高位部分的二进制数据相对于存储的自身的基准信息发生变化时,根据高位部分的二进制作数据进行存储的基准信息的更新。
如前所述的,发送端存储了自身的基准信息,随着与接收端之间持续进行的信息子帧传输,相对存储的自身的基准信息,二进制数据的采集信息中发生变化的位数越来越多,即二进制数据的采集信息和基准信息之间相差越来越大,此时将进行接收端中存储的发送端的基准信息进行更新。
但是,由于发送端也存储了自身的基准信息,以用于控制其在接收端中存储的基准信息的更新,在判断到二进制数据的采集信息中高位部分的二进制数据相对于存储的自身的基准信息发生变化时,也对其存储的自身的基准信息进行更新,以保证后续控制接收端中基准信息更新的即时性和准确性,进而提高了基准信息的可靠性。
在一个实施例中,采集信息为位置信息,位置信息包含经度信息和纬度信息,步骤S630包括:在经度信息和纬度信息中进行二进制数据的提取得到经度信息中低位部分的二进制数据和纬度信息中低位部分的二进制数据。
如前所述的,发送端转换所获得的二进制数据的采集信息是位置信息,则与之相对应的,位置信息是二进制数据,位置信息包含的经度信息和纬度信息也是二进制数据,更进一步的,经度信息包括高位部分的二进制数据和低位部分的二进制数据,纬度信息也包括高位部分的二进制数据和纬度部分的二进制数据。
由此,在二进制数据的采集信息中进行的低位部分的二进制数据提取中,包括了经度信息中低位部分的二进制数据提取和纬度信息中低位部分的二进制数据提取。
在一个实施例中,还相应提供了一种实现信息压缩的通信方法,该方法如图14所示,包括:
步骤S910,接收端接收发送端传输的信息子帧。
接收端将接收到发送端传输的一个或者多个信息子帧,该信息子帧中填充了发送端中二进制数据的采集信息中低位部分的二进制数据。
与发送端所进行的信息子帧传输相对应的,信息子帧由高位至低位的顺序到达接收端,在接收到最低位的信息子帧时即可确认接收完毕。
步骤S930,对接收的信息子帧进行恢复得到低位部分的二进制数据,低位部分的二进制数据是发送端获得的二进制数据的采集信息中低位部分的二进制数据。
将接收的信息子帧全部进行依序拼装等处理即可得到采集信息中低位部分的二进制数据。
步骤S950,根据低位部分的二进制数据和存储的发送端的基准信息还原得到发送端的二进制数据的采集信息。
接收端存储了发送端的基准信息,该基准信息为接收端当前通过信息子帧所恢复得到的低位部分二进制数据提供了高位部分的二进制数据,因此,通过根据存储的发送端的基准信息便可对当前恢复得到的低位部分的二进制数据进行还原,即直接拼接即可。
由此将使得接收端得到了发送端的二进制数据的采集信息,进而实现了此二进制数据的采集信息由发送端传输至接收端,在实现了传输中高压缩率的同时,也保证了接收端中获得信息的完整性和准确性。
在一个实施例中,如上所述的过程还包括:接收端在接收到发送端发送的高位部分的二进制数据时,根据接收的高位部分的二进制数据进行发送端的基准信息的存储。
发送端在进行信息子帧的传输之前,将向接收端发送高位部分的二进制数据,以用于进行接收端中发送端的基准信息的存储。
相对应的,接收端在接收到发送端发送的高位部分的二进制数据时,为发送端进行基准信息的存储,使后续接收端与发送端之间的传输中,接收端能够随时获得发送端的基准信息。
其中,接收端中基准信息的存储将如约定进行。一方面,可将接收的高位部分的二进制数据直接存储为基准信息;另一方面,将接收的高位部分的二进制数据作为基准信息的高位部分,基准信息的低位部分则使用区别于高位部分的二进制数据进行填充。
接收端可以使用上述任意一种实现方式进行基准信息的存储。需要说明的是,对于接收端和发送端所进行的基准信息存储,其可以采集同一实现方式实现,也可以采集不同的实现方式实现,只需要保证实现基准信息存储的高位部分的二进制数据是一致的即可。
进一步的,在本实施例中,接收端在接收到发送端发送的高位部分的二进制数据时,根据接收的高位部分的二进制数据进行发送端的基准信息的存储的步骤包括:
接收端接收发送端发送的高位部分的二进制数据,将高位部分的二进制数据存储为发送端的基准信息,并向发送端发送传输成功确认。
或,接收端接收发送端发送的高位部分的二进制数据,区别于高位部分的二进制数据,对高位部分的二进制数据进行低位填充,将获得的二进制数据存储为基准信息,并向发送端发送传输成功确认。
也就是说,高位部分的二进制数据的传输中,接收端在成功接收此高位部分的二进制数据之后,向发送端发送传输成功确认。
此传输成功确认的发送并不限于在完成了基准信息的获得和存储之后,只要在成功接收高位部分的二进制数据之后即可执行。
在一个实施例中,采集信息为位置信息,位置信息包括经度信息和纬度信息,步骤S930如图15所示,包括:
步骤S931,从接收的信息子帧得到每一信息子帧中经度对应的二进制数据和纬度对应的二进制数据。
发送端所进行的低位部分的二进制数据提取是针对经度信息和纬度信息进行的,即所提取得到的低位部分的二进制数据包括经度信息中低位部分的二进制数据和纬度信息中低位部分的二进制数据,因此,由每一信息子帧所填充的将是经度对应的二进制数据和纬度对应的二进制数据。
步骤S933,根据信息子帧的帧标识拼装每一信息子帧中经度对应的二进制数据,以得到经度信息中低位部分的二进制数据,根据信息子帧的帧标识拼装每一信息子帧中纬度对应的二进制数据,以得到纬度信息中低位部分的二进制数据。
通过简单的拼装即可在接收端中恢复得到发送端所传输的采集信息中低位部分的二进制数据,对于接收端而言,易于实现。
在一个实施例中,基准信息包括基准经度信息中高位部分的二进制数据和基准纬度信息中高位部分的二进制数据,则步骤950包括:
将恢复得到的经度信息中低位部分的二进制数据、纬度信息中低位部分的二进制数据与发送端的基准经度信息中高位部分的二进制数据、基准纬度信息中高位部分的二进制数据拼装为发送端的二进制数据的采集信息。
通过恢复得到的经度信息中低位部分的二进制数据、纬度信息中低位部分的二进制数据在存储的发送端的基准信息中进行低位部分的替换或者直接拼装得到发送端的二进制数据的采集信息。
也就是说,与通过信息子帧进行的低位部分的二进制数据的恢复相类似的,所进行的低位部分的替换和直接拼装也是按照经度和纬度所分别进行的,进而最终获得的二进制数据即为发送端的二进制数据的采集信息。
需要说明的是,二进制数据的采集信息和存储的基准信息均为紧缩格式的二进制数据。
对于作为位置信息的采集信息而言,所得到的二进制数据的采集信息将最终进行球面化处理,进而得到应用信息中包含的采集信息。
接收端中,所得到的二进制数据的采集信息是一维平面形式的,需要将其还原为二维球面形式,以得到作为发送端的通信设备所发送的位置信息。
具体的,与作为发送端的通信设备中其所进行的平面化处理相对应的,通过球面化处理将二进制数据的采集信息转化为初始的采集信息,即位置信息。
其详细过程可如下述公式所示:
Ljo小于108*106时Ew等于0,否则Ew等于1
EDEG=Ljo%(108*106)/(6*105)
EMINmm=Ljo%(108*106)/(104)
EMINF=Ljo%104
Lwo小于54*106时Ns等于0,否则Ns等于1
NDEG=Lwo%(54*106)/(6*105)
NMINmm=Lwo%(54*106)/(104)
NMINF=Lwo%104
其中,Ljo为二进制数据的采集信息中的经度信息,例如,无符号初始经度信息整数;Lwo为二进制数据的采集信息中的纬度信息,例如,无符号初始纬度信息整数;Ew为东西经标识;EDEG为经度;EMINmm为经分的整数部分;EMINF为经分的小数部分;NDEG为纬度;NMINmm为纬分的整数部分;NMINF为纬分的小数部分;Ns是南北纬标识。
通过如上所述的过程,将无符号初始经度信息整数和无符号初始纬度信息整数还原为初始的位置信息。
在另一个实施例中,在对二进制数据的采集信息进行球面化处理之前,如上所述的方法还包括:
根据所需精度对应的信息压缩宽度对二进制数据的采集信息进行精度还原运算得到还原了精度的采集信息。
与发送端相对应的,二进制数据的采集信息包括了无符号紧缩经度信息整数和无符号紧缩纬度信息整数,因此,将对其根据精度和信息压缩宽度对其进行还原,以得到还原了原始精度的采集信息,该采集信息包括无符号初始经度信息整数和无符号初始纬度信息整数。
接收端通过这一方式,将使得紧缩格式的采集信息得到还原出来,以便于后续球面化处理后输出完整的位置信息,进而实现通信应用的各种功能。
通过如上所述的过程,对于运行于通信设备中的各种通信应用可进行各种采集信息的传输,并且保证了传输效率和压缩效率,有效提升了信息传输容量。
需要说明的是,如上所述的过程适用于全球定位信息的传输,该全球定位信息的初始格式可为NMEA格式,也可以是其它的一些格式,对此不进行限定。
通过如上所述的过程,使得进行信息传输的承载空间是动态可变的,而避免了固定完整的信息传输,从而将极大地提高信息压缩效率,避免造成空间的浪费。
在一个实施例中,还相应的提供了一种实现信息压缩的通信装置,如图16所示,包括提取模块110、比对模块130、差分处理模块150和传输模块170,其中:
提取模块110,用于提取应用信息中的采集信息,将采集信息进行转换,获得二进制数据的采集信息。
比对模块130,用于比对获得的二进制数据的采集信息和存储的基准信息得到信息差分,所述信息差分携带有获得的二进制数据的采集信息相对存储的基准信息的低位变化信息。
具体的,比对模块130进一步用于将获得的二进制数据的采集信息和基准信息逐位进行二进制位的比对,得到采集信息相对存储的基准信息的低位变化部分,低位变化部分即为比对得到的所述信息差分。
差分处理模块150,用于根据信息差分得到本次传输的信息子帧。
提取模块110进行所得到的二进制数据的采集信息从高位至低位包括了若干二进制数值,随着本 次传输信息和上一传输信息之间由小到大或由大到小的持续变化,比对所得到的信息差分将是低位变化部分。
根据信息差分,其所对应的低位变化部分即为相对基准信息发生了变化的部分,因此,差分处理模块150由对应的低位部分得到承载信息变化的信息子帧。对于多个连续的信息子帧而言,其可根据所在本次传输中的顺序拼装在一起形成信息差分。
传输模块170,用于传输得到的信息子帧。
通过将如上所述的提取模块110、比对模块130、差分处理模块150和传输模块170应用于作为发送端的通信设备,使得应用信息中采集信息相关内容的传递仅需要通过承载信息变化的信息子帧实现,而不需要对整个采集信息进行传输,大为提高了信息压缩效率和传输效率,进而避免传输过程中的控制信道拥塞。
在另一个实施例中,如上所述的装置还包括传输切换模块,其中:
传输切换模块用于在获得二进制数据的采集信息之后,判断二进制数据的采集信息相对于存储的基准信息的变化是否达到预设的边界值,若为是,则传输完整的二进制数据的采集信息,并在接收到接收端的传输成功的确认后,将存储的基准信息更新为完整的二进制数据的采集信息,若为否,则通知比对模块130。

在一个实施例中,比对模块130进一步用于将获得的二进制数据的采集信息和存储的基准信息逐位进行二进制位的比对,得到获得的二进制数据的采集信息相对存储的基准信息发生变化的部分,变化部分即为比对得到的所述信息差分;
或,比对模块130进一步用于将获得的二进制数据的采集信息和存储的基准信息进行运算,获得获得的二进制数据的采集信息和存储的基准信息的差值,差值即为比对得到的信息差分。
在一个实施例中,采集信息为线性变化信息,该提取模块610进一步用于运算得到线性变化信息和基准的线性变化信息之间紧缩格式的变化信息,该变化信息为获得的二进制数据的采集信息。
如图18所示,在一实施例中,采集信息为线性变化信息,信息差分包括获得的二进制数据的采集信息相对存储的基准信息的变化值和变化趋势标识该差分处理模块150包括变化获取单元151b和低位帧生成单元153b,其中:
变化获取单元151b,用于根据信息差分得到二进制数据的采集信息相对存储的基准信息的变化值和变化趋势标识;
帧生成单元153b,用于由变化值和变化趋势标识生成承载线性变化的信息子帧。
通过如上所述的装置,基于线性变化信息相对传输的变化部分实现信息压缩,进而大为提高了可进行信息压缩的采集信息种类,极大地扩充了应用场景。

需要说明的是,接收模块210、恢复模块230和还原模块250将配置于作为接收端的通信设备中。
在另一个实施例中,如上所述的装置还包括更新确认模块。
更新确认模块用于接收端在接收到发送端发送的完整的二进制数据的采集信息时,将存储的发送端的基准信息更新为完整的二进制数据的采集信息,并向发送端发送传输成功确认。
或,更新确认模块用于接收端在判定还原获得的二进制数据的采集信息与存储的发送端的基准信息相比,变化达到预设的边界值时,将存储的发送端的基准信息更新为还原获得的二进制数据的采集信息,并向发送端发送传输成功的确认。
或,更新确认模块用于在接收端从信息子帧获得采集信息到达边界指示后,将存储的发送端的基准信息更新为还原获得的二进制数据的采集信息,并向发送端发送传输成功确认。
需要特别说明的是,二进制数据的采集信息及存储的基准信息为紧张格式的二进制数据。
进一步的,在另一个实施中,如图20所示,采集信息为位置信息,位置信息包含经度信息和纬度信息,发送端的基准信息包含基准经度信息和基准纬度信息;恢复模块230包括数据提取模块231、数据拼装模块233和接收信息形成模块235,其中:
