本发明涉及通信技术领域，具体提供一种超宽带通信装置、控制方法、***、控制装置及介质。
超宽带(Ultra Wide Band，UWB)技术是一种无线载波技术，其不采用正弦载波，而是利用纳秒级的非正弦模窄脉冲传输数据。现有技术中的超宽带通信装置，由于法规限制了其发射功率，因而需要尽量提升其接收灵敏度，来扩展超宽带通信装置的应用距离。而为超宽带通信装置设置双接收通道以获得合并增益就是其中一个可以提升其接收灵敏度的方法。
同时，由于超宽带通信装置的工作频率较高，其发射的信号很容易受到外界遮挡的影响，现有技术中，一般是通过接收信号的RSSI(Received Signal Strength Indication，接收信号强度指示)来判断接收信号的质量，从而实现智能切换发射天线，来确保发射信号的质量。
为了同时确保超宽带通信装置的接收灵敏度和发射信号的质量，目前行业内多采用多发射多接收的方案。但是，针对双天线方案而言，现有技术中只能实现双通道接收，无法实现发射通道的切换，因而不能够基于接收信号的RSSI实现智能切换发射通道。只能够使用超过三个天线及相应发射通道的方案才能够实现双通道接收和智能切换发射
通道两个功能。这样的方案，不论结构，还是控制逻辑都较为复杂。

参阅附图1，图1是根据本发明的一个实施例的超宽带通信装置的主要组成结构示意图。如图1所示，本发明实施例中的超宽带通信装置主要包括：

效确保超宽带通信装置的应用距离。同时，在进行信号发射时，本发明实施例的超宽带通信装置还能够通过切换开关模块2实现通过第一天线3进行信号发射或通过第二天线4进行信号发射，能够实现信号发射过程中的发射通道的切换。通过上述配置方式，本发明实施例能够只应用两个天线和两个信号接收端，就能够实现信号的双通道接收以及信号发射通道切换的功能，实现了超宽带通信装置的结构的简化。
下面继续参阅附图1，对本发明的超宽带通信装置的具体结构进行进一步地说明。
如图1所示，在本发明实施例的一个实施方式中，切换开关模块2可以包括第一开关单元21、第二开关单元22和第三开关单元23。第一开关单元21的第一端与信号发射端11连接，第一开关单元21的第二端与第二开关单元22的第二端连接，第一开关单元21的第三端与第三开关单元23的第一端连接；第二开关单元22的第一端与第一信号接收端12连接，第二开关单元22的第三端与第一天线3连接；第三开关单元23的第二端与第二信号接收端13连接，第三开关单元23的第二端与第二天线4连接。
在本实施方式中，可以通过第二开关单元22建立第一信号接收端12和第一天线3之间的连接；通过第三开关单元23建立第二信号接收端13和第二天线4之间的连接；通过第一开关单元21和第二开关单元22建立信号发射端11与第一天线3的连接；通过第一开关单元21和第三开关单元23建立信号发射端11与第二天线4的连接。
一个实施方式中，第一开关单元21、第二开关单元22和第三开关单元23可以为SPDT(Single Pole Double Throw，单刀双掷)开关。即，如图1所示，第一开关单元21为SPDT1，第二开关单元22为SPDT2，第三开关单元23为SPDT3。
在本发明实施例的一个实施方式中，超宽带通信转置还可以包括第一滤波模块5和第二滤波模块6。第一滤波模块5的第一端与切换开关模块2连接，第一滤波模块5的第二端与第一天线3连接；第二滤波模块6的第一端与切换开关模块2连接，第二滤波模块6的第二端与第二天线4连接。
在本实施方式中，在进行信号发射时，可以通过第一滤波模块5和第二滤波模块6实现对发射信号的滤波，以提升发射信号的抗干扰能力。
一个实施方式中，超宽带通信装置还可以包括第一取样测试模块7和第二取样测试模块8。第一取样测试模块7的第一端与第一滤波模块5的第二端连接，第一取样测试模块7的第二端与第一天线3连接；第二取样测试模块8的第一端与第二滤波模块6的第二端连接，第二取样测试模块8的第二端与第二天线4连接。
在本实施方式中，在进行信号发射时，可以通过第一取样测试模块7和第二取样测试模块8对发射信号进行取样，以有效监测发射信号的信号质量。
进一步，本发明还提供一种超宽带通信装置的控制方法。
参阅附图2，图2是根据本发明的一个实施例的超宽带通信装置的控制方法的主要步骤流程示意图。如图2所示，本发明实施例中的超宽带通信装置的控制方法主要包括下列步骤S101-步骤S102。
步骤S101：获取超宽带通信装置的工作模式。
在本实施例中，超宽带通信装置的工作模式可以包括信号接收模式和信号发射模式。
步骤S102：根据工作模式，控制切换开关模块2的连接状态，以实现超宽带通信装置的信号发射或接收。
在本实施例中，可以基于超宽带通信装置的工作模式来控制切换开关模块2的连接状态，以实现信号的发射和接收。
通过上述步骤S101和步骤S102，本发明实施例能够实现对超宽带通信装置的有效控制，使得其在不同的工作模式下，实现不同的连接状态，以实现超宽带通信装置在信号接收时实现双通道接收，以及在信号发射时，实现信号发射通道切换的功能。
下面对步骤S102作进一步地说明。
在本发明实施例的一个实施方式中，步骤S102可以进一步包括以下步骤S1021：
步骤S1021：当超宽带通信转置工作在信号接收模式时，控
制切换开关模块2的连接状态，使得第一信号接收端12与第一天线3连接，第二信号接收端13与第二天线4连接，以根据第一天线3获取的第一接收信号和第二天线4获取的第二接收信号，获取最终接收信号，并获取第一天线3和第二天线4的接收信号强度。
在本实施方式中，当超宽带通信装置工作在信号接收模式时，可以通过切换开关模块2建立第一信号接收端12与第一天线3之间的连接，并建立第二信号接收端13与第二天线4之间的连接，从而使得第一天线3接收第一接收信号，第二天线4接收第二接收信号，可以通过叠加第一接收信号和第二接收信号来获取最终接收信号，这样最终接收信号的天线增益就是第一接收信号和第二接收信号的合并增益，从而提升了最终接收信号的信号强度，提升了超宽带通信装置接收信号的接收灵敏度，能够有效扩展超宽带通信装置的应用距离。
同时，超宽带通信装置在接收第一接收信号和第二接收信号时，还能够获取第一天线3和第二天线4的接收信号强度。其中，可以通过RSSI(Received Signal Strength Indication，接收信号强度指示)来确定第一天线3和第二天线4的接收信号强度。RSSI是无线信号收发过程中的一个可选参数，其可以用于判断信号的强度，RSSI越高，说明对应的信号强度越高，信号质量越好。
一个实施方式中，步骤S102除了可以包括上述步骤S1021外，还可以包括以下步骤S1022和步骤S1023：
步骤S1022：当超宽带通信装置工作在信号发射模式时，比较当前信号发射模式的前一个信号接收模式获得的第一天线3和第二天线4的接收信号强度。
步骤S1023：控制切换开关模块2的连接状态，使得信号发射端11与第一天线3和第二天线4中接收信号强度高的天线连接，以将信号发射出去。
在本实施方式中，当超宽带通信装置工作在信号发射模式时，则可以根据前一个信号接收模式获得的接收信号强度来对第一天线3和第二天线4进行选择，选择接收信号强度较高的天线进行信号发射。
可以继续参阅图1，在超宽带通信装置工作在信号接收模式
时，可以控制SPDT2和SPDT3，使得RX1与第一天线3连接，RX2与第二天线4连接，SPDT3状态不限。在超宽带通信装置工作在信号发射模式时，可以控制SPDT1，将TX1与信号较好的天线连接起来，从而通过信号较好的天线将信号发射出去。
需要指出的是，尽管上述实施例中将各个步骤按照特定的先后顺序进行了描述，但是本领域技术人员可以理解，为了实现本发明的效果，不同的步骤之间并非必须按照这样的顺序执行，其可以同时(并行)执行或以其他顺序执行，这些变化都在本发明的保护范围之内。
进一步，本发明还提供了一种超宽带通信装置的控制***。

进一步，应该理解的是，由于各个模块的设定仅仅是为了说明本发明的装置的功能单元，这些模块对应的物理器件可以是处理器本身，或者处理器中软件的一部分，硬件的一部分，或者软件和硬件结合的一部分。因此，图中的各个模块的数量仅仅是示意性的。
本领域技术人员能够理解的是，可以对装置中的各个模块进行适应性地拆分或合并。对具体模块的这种拆分或合并并不会导致技术方案偏离本发明的原理，因此，拆分或合并之后的技术方案都将落入本发明的保护范围内。
