Description
技术领域technical field
本发明实施例涉及通信技术领域，尤其涉及一种天线切换方法及接收装置、终端。Embodiments of the present invention relate to the field of communication technologies, and in particular, to an antenna switching method, a receiving device, and a terminal.
背景技术Background technique
在移动终端领域，为了获得更佳的外观设计，越来越多的厂商使用金属外壳，用户手握移动终端的位置的不同或者金属外壳会对移动终端的天线性能产生影响，为了解决这个问题，通常都会在移动终端上设置主天线及副天线协同工作，有的甚至是三天线、四天线。而且，随着长期演进(LongTerm Evolution，简称：LTE)数据业务的发展，多天线技术可以提供丰富的通信业务。In the field of mobile terminals, in order to obtain a better appearance design, more and more manufacturers use metal casings. Different positions of users holding mobile terminals or metal casings will affect the antenna performance of mobile terminals. In order to solve this problem, Usually, a main antenna and a secondary antenna are set on the mobile terminal to work together, and some even have three or four antennas. Moreover, with the development of Long Term Evolution (LTE for short) data services, the multi-antenna technology can provide rich communication services.
对于多天线移动终端，目前主要采用天线寻优算法来进行天线的选取，具体的，需要通过比较天线的信号接收质量找到信号接收质量较大的天线，现有的天线寻优算法一般包括评估、比较、冻结三个阶段。以四根天线为例，首先在评估阶段，对多天线移动终端中当前正在实现通信的天线进行评估处理，如果当前正在实现通信的天线的信号接收质量小于门限值，则进入比较阶段。在比较阶段，通过依次对四根天线的信号接收质量进行比较，找到四根天线中信号接收质量最大的一根天线，切换并工作在该天线上，即进入冻结阶段。为了防止天线频繁比较切换，设置一个天线工作时间，整轮比较阶段结束后，切换并工作在信号接收质量最高的天线上，进入冻结阶段。天线工作时间结束后再继续进入评估阶段。继续对当前正在实现通信的天线的信号接收质量进行评估。For multi-antenna mobile terminals, the antenna optimization algorithm is currently used to select antennas. Specifically, it is necessary to find the antenna with higher signal reception quality by comparing the signal reception quality of the antennas. The existing antenna optimization algorithms generally include evaluation, Compare and freeze three stages. Taking four antennas as an example, firstly, in the evaluation stage, evaluate the antennas that are currently communicating in the multi-antenna mobile terminal. If the signal reception quality of the antennas that are currently communicating is less than the threshold value, enter the comparison stage. In the comparison stage, by comparing the signal reception quality of the four antennas in turn, find the antenna with the highest signal reception quality among the four antennas, switch and work on this antenna, that is, enter the freezing stage. In order to prevent frequent comparison and switching of antennas, set an antenna working time. After the whole round of comparison phase is over, switch and work on the antenna with the highest signal reception quality, and enter the freezing phase. Continue to the evaluation phase after the antenna working time is over. Continue to evaluate the signal reception quality of the antenna that is currently communicating.
在比较阶段，若第一轮比较出的天线的信号接收质量已经可以满足通信的要求，但是按照上述的天线寻优算法，仍然需要等所有的天线都比较完才能结束，耗时较长。In the comparison stage, if the signal reception quality of the antennas obtained in the first round of comparison can meet the communication requirements, but according to the above antenna optimization algorithm, it still needs to wait for all antennas to be compared before ending, which takes a long time.

具体实施方式detailed description
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明实施例一部分实施例，而不是全部的实施例。基于本发明实施例中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明实施例保护的范围。In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of the embodiments of the present invention, but not all of them. Based on the embodiments in the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the embodiments of the present invention.
本发明实施例提供的天线切换方法及接收装置、终端，可用于多天线终端中，由于金属外壳或用户手握终端的位置的不同会对终端的天线性能产生影响，从而引起多天线之间的切换的场景，或者其它原因造成的天线性能变差需要切换的场景，为了保证终端正常的通讯功能，需要尽快的找到可用的天线，基于对天线稳定性的考虑，需要尽量减少天线切换的次数。下面结合附图详细说明本发明实施例提供的天线切换方法及接收装置、终端。The antenna switching method, receiving device, and terminal provided by the embodiments of the present invention can be used in a multi-antenna terminal. Since the difference in the position of the metal casing or the user's hand holding the terminal will affect the performance of the antenna of the terminal, it will cause the difference between the multiple antennas. In the switching scenario, or the scenario where the antenna performance is degraded due to other reasons and needs to be switched, in order to ensure the normal communication function of the terminal, it is necessary to find an available antenna as soon as possible. Based on the consideration of antenna stability, it is necessary to reduce the number of antenna switching as much as possible. The antenna switching method, receiving device, and terminal provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
图1为本发明天线切换方法中天线切换过程的各个阶段示意图，如图1所示，包括评估阶段、比较阶段、冻结阶段三个阶段，终端在评估阶段对当前天线做评估，如果当前处于工作状态的天线的信号接收质量小于门限值，则进入比较阶段。在比较阶段通过依次与终端的其它天线的信号接收质量做比较，比较出信号接收质量较好的天线并切换到该天线上。为了防止天线频繁比较切换，设置一个天线工作时间，整轮比较阶段结束后，工作在比较出的信号接收质量较好的天线上，进入冻结阶段。天线工作时间结束后再继续进入评估阶段，对当前工作的天线做评估，若当前工作的天线的信号接收质量不小于门限值，则继续停留在当前工作的天线上。Figure 1 is a schematic diagram of each stage of the antenna switching process in the antenna switching method of the present invention. As shown in Figure 1, it includes three stages: the evaluation stage, the comparison stage, and the freezing stage. The terminal evaluates the current antenna in the evaluation stage. If it is currently working The signal receiving quality of the antenna in the state is less than the threshold value, and then enters the comparison stage. In the comparison stage, by comparing with the signal reception quality of other antennas of the terminal in turn, an antenna with better signal reception quality is compared and switched to the antenna. In order to prevent frequent comparison and switching of antennas, set an antenna working time. After the whole round of comparison phase is over, it will work on the antenna with better signal reception quality compared and enter the freezing phase. After the antenna working time is over, continue to enter the evaluation stage, and evaluate the currently working antenna. If the signal reception quality of the currently working antenna is not less than the threshold value, it will continue to stay on the currently working antenna.
现有技术中，依次比较终端的所有天线的信号接收质量，确定出所有天线中信号接收质量最大的天线为第一天线，由于每次在比较阶段，对所有的天线都进行比较，则整个比较过程持续的时间较长，图2为现有的天线切换方法中比较切换的流程示意图，如图2所示，以四根天线为例，初始位置在天线(ANT)2，天线(ANT)0的信号接收质量最好。当天线2的信号接收质量变差，开始进入比较阶段，进行一轮比较。首先进行左右旋比较，切换到天线0，然后进行上下切比较，维持在天线0，接着进行对角切比较，仍然维持在天线0，四根天线比较完，确定出了信号接收质量最好的天线，将会冻结在天线0上一段时间。从上述过程可以发现，天线0的信号接收质量已经足够好，但是现有技术中仍然需要等所有天线都比较完才能结束，耗时较长。为解决这一问题，本发明实施例提出下述解决方法，可提前退出比较阶段，缩短比较时间，即缩短天线选择的时间。In the prior art, the signal reception quality of all antennas of the terminal is compared in turn, and the antenna with the highest signal reception quality among all antennas is determined to be the first antenna. Since all antennas are compared each time in the comparison stage, the entire comparison The duration of the process is relatively long, and Fig. 2 is a schematic diagram of a comparative switching process in an existing antenna switching method. As shown in Fig. 2, taking four antennas as an example, the initial position is antenna (ANT) 2, antenna (ANT) 0 The best signal reception quality. When the signal reception quality of antenna 2 deteriorates, a comparison phase is started and a round of comparison is performed. First, compare left and right, switch to antenna 0, then compare up and down, keep it at antenna 0, then perform diagonal comparison, still keep it at antenna 0, after comparing the four antennas, the antenna with the best signal reception quality is determined , will freeze on antenna 0 for a while. From the above process, it can be found that the signal reception quality of antenna 0 is good enough, but in the prior art, it still needs to wait for all antennas to be compared before ending, which takes a long time. In order to solve this problem, the embodiment of the present invention proposes the following solution, which can exit the comparison stage in advance and shorten the comparison time, that is, shorten the antenna selection time.
图3为本发明天线切换方法实施例一的流程图，本实施例的方法应用于多天线装置，多天线装置包括接收机，第一天线以及至少一个第二天线，接收机当前耦合至第一天线，并通过第一天线接收无线信号，如图3所示，本实施例的方法可以包括：3 is a flow chart of Embodiment 1 of the antenna switching method of the present invention. The method of this embodiment is applied to a multi-antenna device. The multi-antenna device includes a receiver, a first antenna, and at least one second antenna. The receiver is currently coupled to the first antenna, and receive a wireless signal through the first antenna, as shown in Figure 3, the method of this embodiment may include:
S1、测量第一天线的信号接收质量。S1. Measure the signal reception quality of the first antenna.
S2、在确定第一天线的信号接收质量小于预设的第一门限的情况下，从至少一个第二天线中确定信号接收质量大于第一天线的信号接收质量的目标天线，目标天线为首次比较出的信号接收质量大于第一天线的信号接收质量的天线。S2. When it is determined that the signal reception quality of the first antenna is less than the preset first threshold, determine the target antenna whose signal reception quality is greater than the signal reception quality of the first antenna from at least one second antenna, and the target antenna is the first comparison An antenna whose signal reception quality is greater than that of the first antenna.
其中，第一门限满足多天线装置的最低工作信号接收质量。Wherein, the first threshold meets the minimum working signal receiving quality of the multi-antenna device.
S3、将接收机当前耦合的第一天线切换到目标天线，以通过目标天线接收无线信号。S3. Switch the first antenna currently coupled to the receiver to the target antenna, so as to receive wireless signals through the target antenna.
也就是说，天线切换之前，接收机耦合到第一天线，天线切换之后，接收机耦合到目标天线。That is, before the antenna is switched, the receiver is coupled to the first antenna, and after the antenna is switched, the receiver is coupled to the target antenna.
具体地，在评估阶段评估第一天线的信号接收质量，小于第一门限时，则进入比较阶段，从至少一个第二天线中确定出目标天线，只要比较出目标天线的信号接收质量大于第一天线，即可退出比较阶段，目标天线的信号接收质量大于第一天线有多种可能，可能目标天线的信号接收质量大于第一门限，也可能小于第一门限，但是通过这种方式，在终端天线数目较多时，不用将所有的天线都比较完，因此可提前退出比较阶段，缩短比较时间，即缩短天线选择的时间。Specifically, in the evaluation stage, the signal reception quality of the first antenna is evaluated, and when it is less than the first threshold, then enters the comparison stage, and the target antenna is determined from at least one second antenna, as long as the signal reception quality of the target antenna is greater than the first threshold. Antenna, that is, exit the comparison stage. There are many possibilities that the signal reception quality of the target antenna is greater than the first antenna. The signal reception quality of the target antenna may be greater than the first threshold or less than the first threshold. When the number of antennas is large, it is not necessary to compare all the antennas, so the comparison stage can be exited in advance to shorten the comparison time, that is, shorten the antenna selection time.
较优的，目标天线的信号接收质量大于第一门限。在评估阶段评估第一天线的信号接收质量，小于第一门限时，则进入比较阶段，从至少一个第二天线中确定出目标天线，只要比较出目标天线的信号接收质量大于第一门限，也就是只要比较出可用的天线即可退出比较阶段，不用将所有的天线都比较完，因此可提前退出比较阶段，缩短比较时间，即缩短天线选择的时间，这样就可尽快的找到可用的天线，保证了多天线装置正常的通讯功能。Preferably, the signal reception quality of the target antenna is greater than the first threshold. In the evaluation stage, the signal reception quality of the first antenna is evaluated, and if it is less than the first threshold, then enter the comparison stage, and the target antenna is determined from at least one second antenna, as long as the signal reception quality of the target antenna is greater than the first threshold, it is also That is, as long as the available antennas are compared, the comparison stage can be exited. It is not necessary to compare all the antennas. Therefore, the comparison stage can be exited in advance, and the comparison time can be shortened, that is, the antenna selection time can be shortened, so that the available antennas can be found as soon as possible. The normal communication function of the multi-antenna device is guaranteed.
具体来说，在比较阶段根据至少一个第二天线的信号接收质量确定出目标天线，图4为一种根据至少一个第二天线的信号接收质量确定出目标天线的方法流程图，如图4所示，具体可以为：Specifically, in the comparison stage, the target antenna is determined according to the signal reception quality of at least one second antenna. FIG. 4 is a flowchart of a method for determining the target antenna according to the signal reception quality of at least one second antenna, as shown in FIG. 4 Specifically, it can be:
S21、将接收机当前耦合的第一天线切换到某一天线上。S21. Switch the first antenna currently coupled to the receiver to a certain antenna.
具体来说，该天线是随机比较的多天线装置的天线中除当前工作的第一天线之外的一根天线，要获取天线的信号接收质量，必须先切换到天线上，然后获取该天线的信号接收质量。Specifically, this antenna is an antenna other than the currently working first antenna among the antennas of the multi-antenna device for random comparison. To obtain the signal reception quality of the antenna, you must first switch to the antenna, and then obtain the Signal reception quality.
S22、确定所切换到的天线的信号接收质量是否大于第一门限，若是，执行S23。若否，执行S24。S22. Determine whether the signal reception quality of the switched antenna is greater than the first threshold, and if so, perform S23. If not, execute S24.
S23、则比较阶段结束。第一门限满足多天线装置的最低工作信号接收质量，也就是确保找到可用天线，不一定是最优的天线。此时已确定出目标天线，则直接工作在目标天线上。S23, the comparison phase ends. The first threshold satisfies the minimum working signal receiving quality of the multi-antenna device, that is, to ensure that an available antenna is found, not necessarily an optimal antenna. At this point, the target antenna has been determined, then work directly on the target antenna.
S24、进入下一轮比较，执行类似S21-S23的过程。S24. Go to the next round of comparison and perform a process similar to S21-S23.
类似地，切换到下一个天线上，比较下一个天线与第一轮切换的天线的信号接收质量，若该轮切换的天线的信号接收质量大于第一门限，则比较阶段结束。否则继续下一轮。Similarly, switch to the next antenna, and compare the signal reception quality of the next antenna with the antenna switched in the first round. If the signal reception quality of the antenna switched in this round is greater than the first threshold, the comparison phase ends. Otherwise continue to the next round.
通过本实施的上述方法，可以实现在确保找到可用天线的前提下，提前退出比较阶段，缩短比较时间，进而缩短了天线选择的时间，可快速找到可用的天线。Through the above method of this implementation, it can be realized that the comparison stage can be exited in advance under the premise of ensuring that an available antenna can be found, the comparison time can be shortened, and the antenna selection time can be shortened, and an available antenna can be quickly found.
下面采用一个具体的实施例，对图4所示方法实施例的技术方案进行详细说明。A specific embodiment is used below to describe the technical solution of the method embodiment shown in FIG. 4 in detail.
图5为本发明天线切换方法中比较切换的流程示意图，如图5所示，以四根天线为例，其中各个天线的信号接收质量分别为：QANT0＝-80dB，QANT1＝-70dB，QANT2＝-90dB，QANT3＝-60dB，且第一门限Qthreshold为-75dB。Fig. 5 is the flowchart schematic diagram of comparison switching in the antenna switching method of the present invention, as shown in Fig. 5, is example with four antennas, wherein the signal reception quality of each antenna is respectively: Q ANT0 =-80dB, Q ANT1 =-70dB, Q ANT2 =-90dB, Q ANT3 =-60dB, and the first threshold Q threshold is -75dB.
首先，初始ANT2信号接收质量小于第一门限，进入比较阶段。First, the receiving quality of the initial ANT2 signal is less than the first threshold, and enters the comparison stage.
在比较阶段，首先进行左右旋比较，比较QANT2和QANT0，通过天线采样测量，切换到ANT0，但是QANT0小于Qthreshold，继续比较。In the comparison stage, firstly perform left-right rotation comparison, compare Q ANT2 and Q ANT0 , switch to ANT0 through antenna sampling measurement, but Q ANT0 is smaller than Q threshold , and continue the comparison.
接着，将QANT0和QANT1进行比较，切换到ANT1，此时QANT1大于Qthreshold，则退出比较阶段，提前进入冻结阶段，工作在ANT1上。Next, compare Q ANT0 and Q ANT1 , switch to ANT1, and at this time, Q ANT1 is greater than Q threshold , then exit the comparison phase, enter the freezing phase in advance, and work on ANT1.
显然，上述方法可以实现在确保找到可用天线的前提下，提前退出比较阶段，缩短比较时间，进而缩短了天线选择的时间，可快速找到可用的天线。Apparently, the above method can exit the comparison stage in advance under the premise of ensuring that an available antenna can be found, shortening the comparison time, thereby shortening the antenna selection time, and quickly finding an available antenna.
需要说明的是，多天线装置可根据不同业务类别的需求选择采用两种比较阶段中确定出目标天线的方法，当某类业务对时间要求高，需要快速找到可用天线，对天线的性能要求不是很高，则采用提前退出比较阶段的方法，当某类业务对天线的性能要求很高，则采用一般的比较方法，即确定出所有天线中性能最好的天线作为目标天线。It should be noted that the multi-antenna device can choose to use two methods of determining the target antenna in the comparison stage according to the requirements of different service categories. When a certain type of service has high time requirements and needs to quickly find an available antenna, the performance requirements of the antenna are not If it is very high, adopt the method of exiting the comparison stage ahead of time. When a certain type of service requires very high antenna performance, use the general comparison method, that is, determine the antenna with the best performance among all antennas as the target antenna.
本发明实施例还提供一种天线切换方法及接收装置、终端，用于解决现有的天线切换方法中，冻结阶段的天线工作时间是固定设置的，无论天线信号接收质量的好坏都是不变的，因此当所有天线信号接收质量都小于评估阶段的门限(简称评估门限)时，就会重复不停地进入比较阶段，造成天线频繁比较切换，稳定性较差。本发明实施例通过判定在比较阶段比较出的信号接收质量最好的天线的信号接收质量还是小于该评估门限时，天线工作时间延长，工作在比较阶段比较出的信号接收质量最好的天线上的时间延长，天线工作时间结束后再继续进入评估阶段，这样就减少了天线比较的次数，提高了天线的稳定性。下面结合附图详细说明。The embodiment of the present invention also provides an antenna switching method, a receiving device, and a terminal, which are used to solve the problem that in the existing antenna switching method, the working time of the antenna in the freezing stage is fixed, and it does not matter whether the quality of the antenna signal reception is good or bad. Therefore, when the receiving quality of all antenna signals is less than the threshold of the evaluation stage (referred to as the evaluation threshold), it will repeatedly enter the comparison stage, resulting in frequent antenna comparison switching and poor stability. In the embodiment of the present invention, by judging that the signal reception quality of the antenna with the best signal reception quality compared in the comparison stage is still lower than the evaluation threshold, the working time of the antenna is extended, and the antenna works on the antenna with the best signal reception quality compared in the comparison stage. The time of the antenna is extended, and the antenna will continue to enter the evaluation stage after the working time of the antenna is over, which reduces the number of antenna comparisons and improves the stability of the antenna. Describe in detail below in conjunction with accompanying drawing.
图6为本发明天线切换方法实施例二的流程图，本实施例的方法应用于多天线装置，多天线装置包括接收机，第一天线以及至少一个第二天线，接收机当前耦合至第一天线，并通过第一天线接收无线信号，如图6所示，本实施例的方法可以包括：6 is a flow chart of Embodiment 2 of the antenna switching method of the present invention. The method of this embodiment is applied to a multi-antenna device. The multi-antenna device includes a receiver, a first antenna, and at least one second antenna. The receiver is currently coupled to the first antenna, and receive a wireless signal through the first antenna, as shown in Figure 6, the method of this embodiment may include:
S1、测量第一天线的信号接收质量。S1. Measure the signal reception quality of the first antenna.
S2、在确定第一天线的信号接收质量小于预设的第一门限的情况下，从至少一个第二天线中确定出目标天线，目标天线的信号接收质量为至少一个第二天线中信号接收质量最大的天线。S2. When it is determined that the signal reception quality of the first antenna is less than the preset first threshold, determine the target antenna from at least one second antenna, and the signal reception quality of the target antenna is the signal reception quality of at least one second antenna largest antenna.
具体来说，在评估阶段对当前工作的第一天线做评估，确定第一天线的信号接收质量小于第一门限时，进入比较阶段，在比较阶段依次比较多天线装置的所有天线的信号接收质量，确定出所有天线中信号接收质量最大的天线为目标天线，其中的第一门限是评估阶段设置的门限，可根据现有技术中的值设置。Specifically, in the evaluation stage, the first antenna currently working is evaluated, and when it is determined that the signal reception quality of the first antenna is less than the first threshold, the comparison stage is entered, and the signal reception quality of all antennas of the multi-antenna device is compared sequentially in the comparison stage , the antenna with the highest signal reception quality among all the antennas is determined as the target antenna, and the first threshold is the threshold set in the evaluation stage, which can be set according to the value in the prior art.
其中，从至少一个第二天线中确定出目标天线，具体可以为：依次比较多天线装置的第一天线与至少一个第二天线的信号接收质量，确定出所有天线中信号接收质量最大的天线为目标天线。以多天线装置有四根天线为例，依次比较四根天线的信号接收质量，确定出四根天线中信号接收质量最大的天线，将该天线作为目标天线。具体如何获得每根天线的信号接收质量，可以是通过天线切换，切换到某一根天线上时，由处理器对切换到的天线进行采样测量，获取该天线的信号接收质量。Wherein, determining the target antenna from at least one second antenna may be specifically: comparing the signal reception quality of the first antenna of the multi-antenna device and at least one second antenna in turn, and determining the antenna with the highest signal reception quality among all antennas is target antenna. Taking the multi-antenna device with four antennas as an example, the signal reception quality of the four antennas is compared in turn, and the antenna with the highest signal reception quality among the four antennas is determined, and this antenna is used as the target antenna. Specifically, how to obtain the signal reception quality of each antenna may be through antenna switching. When switching to a certain antenna, the processor samples and measures the switched antenna to obtain the signal reception quality of the antenna.
S3、将接收机当前耦合的第一天线切换到目标天线。S3. Switch the first antenna currently coupled to the receiver to the target antenna.
S4、判断目标天线的信号接收质量是否小于第一门限。S4. Determine whether the signal reception quality of the target antenna is less than a first threshold.
若是，即目标天线的信号接收质量小于第一门限，则在第一时间结束后，重新确定目标天线的信号接收质量与第一门限的关系(返回执行S2)，即就是再次进入评估阶段，继续执行上述操作，第一时间大于第二时间。If so, that is, the signal reception quality of the target antenna is less than the first threshold, then after the end of the first time, re-determine the relationship between the signal reception quality of the target antenna and the first threshold (return to execute S2), that is, enter the evaluation stage again, continue Executing the above operations, the first time is greater than the second time.
其中，第二时间为预设的天线工作时间，当目标天线的信号接收质量还是小于第一门限，也就是说所有天线的信号接收质量均不好时，则按照第一时间工作在目标天线上，第一时间结束后再继续进入评估阶段。即就是在循环执行评估阶段-比较阶段-冻结阶段的过程中，若满足第二时间延长的条件，则按照延长的天线工作时间工作在所切换的天线上，这样就减少了天线比较的次数，提高了天线的稳定性。Wherein, the second time is the preset antenna working time, when the signal reception quality of the target antenna is still lower than the first threshold, that is to say, when the signal reception quality of all antennas is not good, then work on the target antenna according to the first time , continue to enter the evaluation stage after the end of the first time. That is, in the process of cyclically executing the evaluation stage-comparison stage-freeze stage, if the second time extension condition is satisfied, the antenna will be switched according to the extended antenna working time, thus reducing the number of antenna comparisons, Improved antenna stability.
若目标天线的信号接收质量大于或等于第一门限，则在第二时间结束后，重新确定目标天线的信号接收质量与第一门限的关系(返回执行S2)，即就是再次进入评估阶段，继续执行上述操作。也就是说，判断出并非所有的天线信号接收质量均不好时，按照预设的第二时间工作。If the signal reception quality of the target antenna is greater than or equal to the first threshold, then after the second time ends, re-determine the relationship between the signal reception quality of the target antenna and the first threshold (return to execute S2), that is, enter the evaluation stage again, continue Do the above. That is to say, when it is judged that not all antennas have poor signal reception quality, work according to the preset second time.
进一步地，作为一种可实施的方式，预先设置的第一时间等于自适应系数A乘以第二时间，其中1≤A≤Amax，A与循环次数成正比，Amax为预设值。例如，A按照循环次数逐级加1，第一轮A为1，第二轮A为2，第三轮A为3……，又如，A按照循环次数逐级加0.5，第一轮A为1，第二轮A为1.5，第三轮A为2……，还可以是别的方式逐级增加，具体可按照实际的应用场景进行设置，当然，逐级增加后的A的值也不能太大，需满足不大于Amax，Amax为根据实际场景或经验值做出的预设值。Further, as an implementable manner, the preset first time is equal to the adaptive coefficient A multiplied by the second time, where 1≤A≤Amax, A is proportional to the number of cycles, and Amax is a preset value. For example, A increases by 1 step by step according to the number of cycles, the first round of A is 1, the second round of A is 2, the third round of A is 3..., and for another example, A is incremented by 0.5 according to the number of cycles, the first round of A is is 1, the second round A is 1.5, the third round A is 2..., and it can also be increased step by step in other ways, which can be set according to the actual application scenario. Of course, the value of A after the step-by-step increase is also It should not be too large, and must not be greater than Amax. Amax is a preset value based on actual scenarios or empirical values.
本实施例提供的天线切换方法，通过确定在比较阶段比较出的信号接收质量最好的目标天线的信号接收质量还是小于第一门限时，则按照第一时间工作在第一天线上，第一时间结束后再继续进入评估阶段，第一时间大于第二时间，第二时间为预设的天线工作时间，即在循环执行评估阶段-比较阶段-冻结阶段的过程中，若满足预设的天线工作时间延长的条件，则按照延长后的第一时间工作在所切换的天线上，当所有天线的信号接收质量都小于第一门限时，这样就减少了天线比较的次数，提高了天线的稳定性。The antenna switching method provided in this embodiment works on the first antenna according to the first time by determining that the signal reception quality of the target antenna with the best signal reception quality compared in the comparison stage is still lower than the first threshold. Continue to enter the evaluation stage after the time is over. The first time is greater than the second time. The second time is the preset antenna working time. If the working time is extended, it will work on the switched antenna according to the first time after the extension. When the signal reception quality of all antennas is less than the first threshold, this reduces the number of antenna comparisons and improves the stability of the antenna. sex.
下面采用一个具体的实施例，详细说明本发明天线切换方法中预先设置的第一时间等于自适应系数A乘以第二时间，其中1≤A≤Amax，A与循环次数成正比，Amax为预设值时的详细过程。以Amax＝3为例，图7为本发明天线切换方法实施例二的流程图，如图7所示，本实施例的方法包括：A specific embodiment is used below to describe in detail that the preset first time in the antenna switching method of the present invention is equal to the adaptive coefficient A multiplied by the second time, where 1≤A≤Amax, A is proportional to the number of cycles, and Amax is the preset The detailed process when setting the value. Taking Amax=3 as an example, FIG. 7 is a flow chart of Embodiment 2 of the antenna switching method of the present invention. As shown in FIG. 7, the method of this embodiment includes:
S31、在评估阶段确定当前工作的第一天线的信号接收质量小于第一门限。S31. In the evaluation phase, determine that the signal reception quality of the currently working first antenna is less than a first threshold.
S32、依次比较多天线装置的第一天线与至少一个第二天线的信号接收质量，确定出所有天线中信号接收质量最大的天线，作为目标天线，同时将接收机当前耦合的第一天线切换到目标天线上。S32. Comparing the signal reception quality of the first antenna of the multi-antenna device and at least one second antenna in turn, determining the antenna with the highest signal reception quality among all antennas as the target antenna, and simultaneously switching the first antenna currently coupled to the receiver to on the target antenna.
S33、判断目标天线的信号接收质量是否小于第一门限，是则执行S34，否则执行S35。S33 , judging whether the signal reception quality of the target antenna is lower than the first threshold, if yes, execute S34 , otherwise execute S35 .
S34、A++，A不大于3，第一时间＝第二时间×A。S34, A++, A is not greater than 3, first time=second time×A.
S35、A＝1，第一时间＝第二时间×A。S35, A=1, first time=second time×A.
S36、在第一时间结束后，进入评估阶段，循环执行上述操作。S36. After the end of the first time period, enter the evaluation stage, and perform the above operations in a loop.
本实施例中，天线工作时间的延长是随着循环次数逐级增加的。相比较而言，自适应延长天线工作时间的效果更好。In this embodiment, the prolongation of the working time of the antenna increases step by step with the number of cycles. In comparison, the effect of adaptively extending the working time of the antenna is better.

The switching device 13 switches between different antennas according to the instructions of the processor 12 .
较优地，目标天线的信号接收质量大于第一门限。也就是只要比较出可用的天线即可退出比较阶段，不用将所有的天线都比较完，因此可提前退出比较阶段，缩短比较时间，即缩短天线选择的时间。Preferably, the signal reception quality of the target antenna is greater than the first threshold. That is, as long as the available antennas are compared, the comparison stage can be exited, and it is not necessary to compare all the antennas. Therefore, the comparison stage can be exited in advance, and the comparison time can be shortened, that is, the antenna selection time can be shortened.
本发明实施例提供的接收装置，可以执行图3所示方法实施例，其实现原理类似，在此不再赘述。The receiving device provided by the embodiment of the present invention can execute the method embodiment shown in FIG. 3 , and its implementation principle is similar, so it will not be repeated here.
本实施例提供的接收装置，在比较阶段，只要确定出大于当前处于工作状态的天线的信号接收质量的天线，则退出比较阶段，进入冻结阶段工作在确定出的目标天线上，这样可提前退出比较阶段，缩短比较时间，进而缩短了天线选择的时间，可快速找到可用的天线。In the receiving device provided by this embodiment, in the comparison phase, as long as an antenna whose signal receiving quality is greater than that of the currently working antenna is determined, it exits the comparison phase and enters the freezing phase to work on the determined target antenna, so that it can exit in advance In the comparison stage, the comparison time is shortened, thereby shortening the antenna selection time, and the available antenna can be quickly found.

The processor 22 is also used for: when it is judged that the signal reception quality of the target antenna is less than the first threshold, then after the end of the first time, re-determine the relationship between the signal reception quality of the target antenna and the first threshold, and the first time is greater than the second threshold. time, the second time is the preset antenna working time.
即就是说，当目标天线的信号接收质量还是小于第一门限，也就是说所有天线的信号接收质量均不好时，则按照第一时间工作在目标天线上，第一时间结束后再继续进入评估阶段。在循环执行评估阶段-比较阶段-冻结阶段的过程中，若满足第二时间延长的条件，则按照延长的天线工作时间(即第一时间)工作在所切换的天线上，这样就减少了天线比较的次数，提高了天线的稳定性。That is to say, when the signal reception quality of the target antenna is still lower than the first threshold, that is to say, when the signal reception quality of all antennas is not good, work on the target antenna according to the first time, and continue to enter after the first time is over. evaluation stage. In the process of cyclically executing the evaluation phase-comparison phase-freeze phase, if the second time extension condition is satisfied, the antenna will be switched according to the extended antenna working time (i.e. the first time), thus reducing the number of antennas The number of comparisons improves the stability of the antenna.
若目标天线的信号接收质量大于或等于第一门限，则处理器22在第二时间结束后，重新确定目标天线的信号接收质量与第一门限的关系。即就是再次进入评估阶段，判断出并非所有的天线信号接收质量均不好时，按照预设的第二时间工作。If the signal reception quality of the target antenna is greater than or equal to the first threshold, the processor 22 re-determines the relationship between the signal reception quality of the target antenna and the first threshold after the second time elapses. That is, when entering the evaluation stage again and judging that not all the antenna signal reception quality is poor, work according to the preset second time.
进一步地，第一时间等于自适应系数A乘以第二时间，其中1≤A≤Amax，A与循环次数成正比，Amax为预设值。Further, the first time is equal to the adaptive coefficient A multiplied by the second time, where 1≤A≤Amax, A is proportional to the number of cycles, and Amax is a preset value.
