Description

一种遥控信号的处理方法、遥控设备及遥控系统Remote control signal processing method, remote control equipment and remote control system 技术领域Technical field
本发明涉及通信技术领域,尤其涉及一种遥控信号的处理方法、遥控设备及遥控系统。The present invention relates to the field of communication technology, in particular to a remote control signal processing method, remote control equipment and remote control system.

The remote control device corresponding to the movable platform can transmit remote control signals to the movable platform through an analog remote control link or a digital remote control link. The analog remote control link has weak anti-interference ability and cannot realize long-distance transmission, but there is no delay and jitter. The digital remote control link has the advantages of high accuracy, long transmission distance, and strong anti-interference ability, but the delay jitter is large, and packet loss occurs in a low signal-to-noise ratio environment.

具体实施方式detailed description
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,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
下面结合附图,对本发明的一些实施方式作详细说明。在不冲突的情况下,下述的实施例及实施例中的特征可以相互组合。Hereinafter, some embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.
在控制系统中,可移动平台对应的遥控设备可以通过模拟遥控链路或者数字遥控链路向可移动平台传输遥控信号。模拟遥控链路抗干扰能力弱,无法实现远距离传输,但是不存在延时抖动的情况。数字遥控链路具备精度高,传输距离远,抗干扰能力强等优点,但是延时抖动较大,低信噪比环境下有丢包现象。为了兼顾遥控信号的精确性和鲁棒性,本发明实施例提出一种遥控信号的处理方法,该方法可在数字系统的基础上,通过信道编码的方式获取第一遥控信号,并通过信号调制的方式获取第二遥控信号,使得第一遥控信号有较高的精确性,第二遥控信号有较高的鲁棒性,以兼顾遥控信号的精确性和鲁棒性。In the control system, the remote control device corresponding to the movable platform can transmit remote control signals to the movable platform through an analog remote control link or a digital remote control link. The analog remote control link has weak anti-interference ability and cannot realize long-distance transmission, but there is no delay and jitter. The digital remote control link has the advantages of high accuracy, long transmission distance, and strong anti-interference ability, but the delay jitter is large, and packet loss occurs in a low signal-to-noise ratio environment. In order to take into account the accuracy and robustness of the remote control signal, the embodiment of the present invention proposes a remote control signal processing method, which can obtain the first remote control signal through channel coding based on the digital system, and modulate the signal. The second remote control signal is acquired in a way, so that the first remote control signal has higher accuracy, and the second remote control signal has higher robustness, so as to take into account the accuracy and robustness of the remote control signal.
本发明实施例提供一种遥控系统,如图1所示,该遥控系统包括遥控设备和电子设备。其中,遥控设备是具有遥控功能的一种设备(如遥控器、手机、平板电脑、地面控制站等),用于通过向电子设备发送遥控信号以控制电子设备的移动以及执行相关的功能操作。例如,遥控设备可以控制电子设备的移动方向(如向左移动或向右移动),还可以控制电子设备的移动速度(如以20公里/小时移动)。又例如,当电子设备具备拍摄功能时,遥控设备可以控制电子设备进行图像拍摄。An embodiment of the present invention provides a remote control system. As shown in FIG. 1, the remote control system includes a remote control device and an electronic device. Among them, a remote control device is a device with a remote control function (such as a remote control, a mobile phone, a tablet computer, a ground control station, etc.), which is used to control the movement of the electronic device and perform related functional operations by sending a remote control signal to the electronic device. For example, the remote control device can control the moving direction of the electronic device (such as moving to the left or right), and can also control the moving speed of the electronic device (such as moving at 20 km/h). For another example, when the electronic device has a shooting function, the remote control device can control the electronic device to perform image shooting.
可移动平台是被所述遥控设备控制的设备,用于根据遥控设备的遥控信号进行移动或执行相关的功能操作。例如,可移动平台根据接收到的遥控设备的遥控信号确定向前移动或向后移动。又例如,当遥控设备的遥控信号包括执行定点悬停时,可移动平台根据接收到的遥控设备的遥控信号在指定的定点停止移动。其中,可移动平台可以为无人机、无人车或者移动机器人等。可以理解 的是,遥控设备和被遥控的可移动平台可以是一一对应的关系,也可以是一个遥控设备对应多个被遥控的可移动平台,通过在遥控设备上切换控制以实现对多个可移动平台的遥控控制。图1所示的遥控系统仅为一种示例,该遥控系统还可以包括多个遥控设备和多个可移动平台,本实施例不作限制。The movable platform is a device controlled by the remote control device, and is used to move or perform related functional operations according to the remote control signal of the remote control device. For example, the movable platform determines to move forward or backward according to the received remote control signal of the remote control device. For another example, when the remote control signal of the remote control device includes the execution of fixed-point hovering, the movable platform stops moving at the designated fixed point according to the received remote control signal of the remote control device. Among them, the movable platform can be an unmanned aerial vehicle, an unmanned vehicle, or a mobile robot. It is understandable that the remote control device and the remotely controlled movable platform can have a one-to-one correspondence, or one remote control device corresponds to multiple remotely controlled movable platforms. By switching control on the remote control device to achieve multiple Remote control of movable platform. The remote control system shown in FIG. 1 is only an example, and the remote control system may also include multiple remote control devices and multiple movable platforms, which is not limited in this embodiment.
在本发明实施例提供的遥控系统中,遥控设备和可移动平台之间采用数字系统,例如正交频分复用技术(Orthogonal Frequency Division Multiplexing,OFDM)系统。数字系统可以包括数字遥控链路。通常来讲,数字遥控链路包括以下几个部分:遥杆,采集,数模/模数转换,编码,发送,接收,解码和输出。数字遥控链路中传输的遥控信号的遥控信号负载通常包括遥控通道数、杆量位宽或杆量频率中的一个或多个。其中,遥控通道数对应了遥控设备可以实现的多种遥控功能,包括不同用途的遥杆、拨杆、开关和按键等,遥控通道数越多,遥控设备的功能越丰富。杆量位宽表示遥控设备传输的控制杆量对应的比特数,当杆量位宽越高(比特数越多)时,遥控设备可以实现更微小精确的操作,当杆量位宽越低(比特数越少)时,遥控设备的操作越粗糙,可能出现遥控不到位的情况。杆量频率表示遥控杆量的发送频率,当杆量频率越高时,遥控设备的控制手感越灵敏,当杆量频率越低时,遥控设备的控制手感越迟钝。通常来讲,遥控设备的杆量频率在50Hz-200Hz之间,遥控设备具备较好的操控性。In the remote control system provided by the embodiment of the present invention, a digital system is adopted between the remote control device and the movable platform, such as an orthogonal frequency division multiplexing (OFDM) system. The digital system may include a digital remote control link. Generally speaking, a digital remote control link includes the following parts: remote control, acquisition, digital-analog/analog-to-digital conversion, encoding, sending, receiving, decoding and output. The remote control signal load of the remote control signal transmitted in the digital remote control link usually includes one or more of the number of remote control channels, the position width of the rod, or the frequency of the rod. Among them, the number of remote control channels corresponds to the multiple remote control functions that the remote control device can achieve, including remote sticks, levers, switches, and buttons for different purposes. The more remote control channels there are, the more functions the remote control device has. The rod amount width represents the number of bits corresponding to the amount of control rod transmitted by the remote control device. When the rod amount width is higher (the number of bits is more), the remote control device can achieve a more minute and precise operation. When the rod amount width is lower ( When the number of bits is less), the operation of the remote control device is rougher, and the remote control may not be in place. The lever frequency represents the sending frequency of the remote control lever. When the frequency of the lever is higher, the control feel of the remote control device is more sensitive, and when the frequency of the lever is lower, the control feel of the remote control device is more sluggish. Generally speaking, the lever frequency of the remote control device is between 50Hz-200Hz, and the remote control device has better controllability.
本发明实施例提供一种遥控信号的处理方法,请参见图2,该方法可以应用于图1所示的遥控系统中,具体包括以下步骤:The embodiment of the present invention provides a remote control signal processing method. Please refer to FIG. 2. The method can be applied to the remote control system shown in FIG. 1, and specifically includes the following steps:
S201,遥控设备基于遥控信号负载采集遥控信号。S201: The remote control device collects a remote control signal based on the remote control signal load.
遥控设备可以基于遥控信号负载采集遥控信号,其中,遥控信号负载可以包括遥控通道数、杆量频率以及杆量位宽中的一种或多种。The remote control device may collect remote control signals based on the remote control signal load, where the remote control signal load may include one or more of the number of remote control channels, the frequency of the lever, and the width of the lever.
举例来说,假设遥控通道数包括3个遥杆和5个控制按键,则遥控设备可以采集用户对遥控设备中3个遥杆和5个控制按键中的部分或者全部进行操作时生成的遥控信号。假设杆量频率为50Hz,则遥控设备可以每间隔0.02秒(s)采集一次遥控信号。假设杆量位宽为128比特,则遥控设备可以生成比特数为128比特的遥控信号。For example, assuming that the number of remote control channels includes 3 joysticks and 5 control buttons, the remote control device can collect the remote control signals generated when the user operates some or all of the 3 joysticks and 5 control buttons in the remote control device . Assuming that the lever frequency is 50 Hz, the remote control device can collect a remote control signal every 0.02 second (s). Assuming that the rod measurement bit width is 128 bits, the remote control device can generate a remote control signal with a bit number of 128 bits.
S202,遥控设备对遥控信号进行信道编码得到第一遥控信号,并对遥控信号进行信号调制得到第二遥控信号。S202: The remote control device performs channel coding on the remote control signal to obtain a first remote control signal, and performs signal modulation on the remote control signal to obtain a second remote control signal.
遥控设备可以在数字系统对遥控信号进行数字信号处理,例如对遥控信号进行信道编码得到第一遥控信号,第一遥控信号包括校验码。可移动平台接收到第一遥控信号之后,可以通过校验码对第一遥控信号进行校验,若校验成功,则可移动平台确定成功接收到第一遥控信号;若校验失败,则可移动平台确定未成功接收到第一遥控信号,即可移动平台不能对第一遥控信号进行处理。由此可知,第一遥控信号的精确度较高。The remote control device may perform digital signal processing on the remote control signal in the digital system, for example, perform channel coding on the remote control signal to obtain the first remote control signal, and the first remote control signal includes a check code. After the mobile platform receives the first remote control signal, the first remote control signal can be verified by the check code. If the verification is successful, the mobile platform determines that the first remote control signal is successfully received; if the verification fails, it can The mobile platform determines that the first remote control signal is not successfully received, that is, the mobile platform cannot process the first remote control signal. It can be seen that the accuracy of the first remote control signal is relatively high.
遥控设备还可以在数字系统对遥控信号进行模拟信号处理,例如对遥控信号进行信号调制得到第二遥控信号。由于第二遥控信号不包括校验码,那么可移动平台接收到第二遥控信号之后,不会对第二遥控信号进行校验,而是直接存储第二遥控信号,传输延时较小,即第二遥控信号的鲁棒性较高。The remote control device can also perform analog signal processing on the remote control signal in the digital system, for example, perform signal modulation on the remote control signal to obtain the second remote control signal. Since the second remote control signal does not include the check code, after the mobile platform receives the second remote control signal, it will not check the second remote control signal, but directly store the second remote control signal, and the transmission delay is small, that is, The robustness of the second remote control signal is relatively high.
S203,遥控设备将第一遥控信号和第二遥控信号通过数字系统发送给可移动平台。S203: The remote control device sends the first remote control signal and the second remote control signal to the movable platform through the digital system.
在一种实现方式中,遥控设备可以将所述第一遥控信号和所述第二遥控信号通过数字遥控链路发送给所述可移动平台。In an implementation manner, the remote control device may send the first remote control signal and the second remote control signal to the movable platform through a digital remote control link.
S204,可移动平台对第一遥控信号进行信道解码,得到第三遥控信号。S204: The movable platform performs channel decoding on the first remote control signal to obtain a third remote control signal.
可移动平台接收到第一遥控信号之后,可以对第一遥控信号进行信道解码,得到第三遥控信号。After receiving the first remote control signal, the movable platform can perform channel decoding on the first remote control signal to obtain a third remote control signal.
在一种实现方式中,若可移动平台未成功接收所述第一遥控信号或者对所述第一遥控信号解码失败,则对所述第二遥控信号进行信号解调,得到第四遥控信号,存储所述第四遥控信号。In an implementation manner, if the movable platform fails to receive the first remote control signal or fails to decode the first remote control signal, then perform signal demodulation on the second remote control signal to obtain a fourth remote control signal, Store the fourth remote control signal.
在该实施例中,若可移动平台未成功接收所述第一遥控信号或者对所述第一遥控信号解码失败,则可移动平台无法使用第一遥控信号,也就无法通过第一遥控信号对可移动平台进行控制。由于第二遥控信号不包括校验码,则可移动平台接收到第二遥控信号之后,可对所述第二遥控信号进行信号解调,得到第四遥控信号,存储所述第四遥控信号,进而通过第四遥控信号对可移动平台进行控制,提高第二遥控信号的鲁棒性。In this embodiment, if the movable platform does not successfully receive the first remote control signal or fails to decode the first remote control signal, the movable platform cannot use the first remote control signal, and cannot use the first remote control signal to pair The movable platform can be controlled. Since the second remote control signal does not include the check code, after receiving the second remote control signal, the movable platform can demodulate the second remote control signal to obtain a fourth remote control signal, and store the fourth remote control signal, Furthermore, the movable platform is controlled through the fourth remote control signal, which improves the robustness of the second remote control signal.
S205,可移动平台对第二遥控信号进行信号解调,得到第四遥控信号。S205: The movable platform performs signal demodulation on the second remote control signal to obtain a fourth remote control signal.
S206,可移动平台将第三遥控信号和第四遥控信号进行关联存储。S206: The movable platform associates and stores the third remote control signal and the fourth remote control signal.
在一种实现方式中,可移动平台将第三遥控信号和第四遥控信号进行关联存储之后,可以获取当前业务需求,若当前业务需求为第一业务需求,可移动平台可以对第三遥控信号进行处理。若当前业务需求为第二业务需求,可移动平台可以对所述第四遥控信号进行处理。例如,可移动平台可以响应第三遥控信号或者第四遥控信号改变可移动平台的姿态信息、移动速度或者进行图像拍摄等。In one implementation, after the mobile platform associates and stores the third remote control signal and the fourth remote control signal, the current business demand can be obtained. If the current business demand is the first business demand, the mobile platform can respond to the third remote control signal To process. If the current service requirement is the second service requirement, the movable platform may process the fourth remote control signal. For example, the movable platform may respond to the third remote control signal or the fourth remote control signal to change the posture information, moving speed, or image shooting of the movable platform.
其中,第一业务需求可以为远距离传输或者高精度传输。第二业务需求可以为低延时传输或者高频度传输。Among them, the first service requirement may be long-distance transmission or high-precision transmission. The second service requirement can be low-delay transmission or high-frequency transmission.
例如,在遥控设备控制可移动平台进行图像拍摄的场景中,对遥控信号的精度需求或者远距离传输需求较高,则可移动平台可以确定当前业务需求为第一业务需求。那么可移动平台接收到第一遥控信号之后,可以对第一遥控信号进行信道解码,得到第三遥控信号,进而对第三遥控信号进行处理。For example, in a scene in which a remote control device controls a movable platform for image shooting, the accuracy requirement of the remote control signal or the requirement for long-distance transmission is high, the movable platform can determine that the current service requirement is the first service requirement. Then, after receiving the first remote control signal, the movable platform can perform channel decoding on the first remote control signal to obtain a third remote control signal, and then process the third remote control signal.
又如,在穿越机竞赛场景中,对遥控信号的低延时需求或者高频度需求较高,则可移动平台可以确定当前业务需求为第二业务需求。那么可移动平台接收到第二遥控信号之后,可以对第二遥控信号进行信号解调,得到第四遥控信号,进而对第四遥控信号进行处理。For another example, in a traversing machine competition scenario, where the low-latency or high-frequency requirements of remote control signals are high, the mobile platform can determine that the current business demand is the second business demand. Then, after receiving the second remote control signal, the movable platform can demodulate the second remote control signal to obtain a fourth remote control signal, and then process the fourth remote control signal.
本发明实施例提供一种遥控信号的处理方法,遥控设备基于遥控信号负载采集遥控信号,对遥控信号进行信道编码得到第一遥控信号,并对遥控信号进行信号调制得到第二遥控信号,将第一遥控信号和第二遥控信号通过数字系统发送给可移动平台,可移动平台对第一遥控信号进行信道解码,得到第三遥控信号,对第二遥控信号进行信号解调,得到第四遥控信号,然后将第三遥控信号和第四遥控信号进行关联存储,可兼顾遥控信号的精确性和鲁棒性。The embodiment of the present invention provides a remote control signal processing method. The remote control device collects the remote control signal based on the remote control signal load, performs channel coding on the remote control signal to obtain the first remote control signal, and performs signal modulation on the remote control signal to obtain the second remote control signal. A remote control signal and a second remote control signal are sent to the mobile platform through the digital system. The mobile platform decodes the first remote control signal to obtain the third remote control signal, and demodulates the second remote control signal to obtain the fourth remote control signal. , And then the third remote control signal and the fourth remote control signal are associated and stored, which can take into account the accuracy and robustness of the remote control signal.
