本发明实施例提供的射频信号接收模块控制方法，射频信号接收模块获取到的射频信号通过局部连接网络LIN总线发送至车身控制器，即射频信号接收模块与车身控制器之间通过LIN总线进行通讯。由于LIN总线结构简单、配置灵活，从而能够实现射频信号接收模块与车身控制器的分离设置，这样一来，可以有效避免由于射频信号接收模块所处无线电环境不佳而造成的射频信号接收灵敏度下降的问题，显著提高了射频信号接收的灵敏度。The radio frequency signal receiving module control method provided by the embodiment of the invention sends the radio frequency signal obtained by the radio frequency signal receiving module to the vehicle body controller through the local connection network LIN bus, that is, the communication between the radio frequency signal receiving module and the vehicle body controller through the LIN bus . Due to the simple structure and flexible configuration of the LIN bus, the separation of the RF signal receiving module and the body controller can be realized, so that the receiving sensitivity of the RF signal due to the poor radio environment of the RF signal receiving module can be effectively avoided. The problem has significantly improved the sensitivity of RF signal reception.
需要说明的是，车载LIN总线通常主要用作控制器局域网络CAN(英文：Controller Area Network)等高速总线的辅助网络或子网络。在带宽要求不高、功能简单、实时性要求相对较低的场合，如车身电器的控制等方面。LIN总线是一种低成本的串行通信网络，其基于通用的异步串行通讯收发接口(英文：Universal Asynchronous Receiver/Transmitter，简称：USRT)，几乎所有微控制器都具备LIN必需的硬件。
It should be noted that the onboard LIN bus is usually mainly used as an auxiliary network or subnetwork of a high speed bus such as a controller area network CAN (English: Controller Area Network). In areas where bandwidth requirements are low, functions are simple, and real-time requirements are relatively low, such as the control of body appliances. The LIN bus is a low-cost serial communication network based on the universal asynchronous serial communication transceiver interface (English: Universal Asynchronous Receiver/Transmitter, referred to as: USRT). Almost all microcontrollers have the necessary hardware for LIN.
在本发明实施例中，射频信号接收模块与车身控制器分离设置。通过将射频信号接收模块从车身控制器中分离出来单独成为一个LIN控制器，在实际应用的过程中，可以将射频信号接收模块布置在车身A柱或C柱上，或者也可集成于顶灯或布置在顶棚上。布置在这些位置空间高、开阔且附近也没有很多的用电设备，从而对射频信号的吸收微弱，有效提高了接收灵敏度，遥控接收效果也随之大大改善。另一方面，针对不同车型，遥控接收的一致性也可以得到很好地保证。In an embodiment of the invention, the radio frequency signal receiving module is disposed separately from the body controller. By separately separating the RF signal receiving module from the body controller into a LIN controller, in the actual application process, the RF signal receiving module can be arranged on the A-pillar or C-pillar of the vehicle body, or can be integrated into the ceiling light or Placed on the ceiling. Arranged in these locations, the space is high, open and there are not many electrical equipment in the vicinity, so that the absorption of the RF signal is weak, the receiving sensitivity is effectively improved, and the remote control receiving effect is also greatly improved. On the other hand, the consistency of remote control reception can be well guaranteed for different models.
其中，射频信号接收模块通过LIN总线将获取到的射频信号发送至车身控制器可以包括：The radio frequency signal receiving module sends the acquired radio frequency signal to the vehicle body controller through the LIN bus, which may include:
当+15节点线路关闭时，车身控制器向射频信号接收模块发送报文以告知射频信号接收模块遥控门禁RKE(英文：Remote Keyless Entry)开始工作，射频信号接收模块收到报文后向车身控制器发送反馈信息，告知已经收到，否则车身控制器继续发送报文，直到射频信号接收模块回复为止。When the +15 node line is closed, the body controller sends a message to the RF signal receiving module to inform the RF signal receiving module that the remote access RKE (English: Remote Keyless Entry) starts to work, and the RF signal receiving module receives the message and then controls the body. The device sends a feedback message to inform that it has been received, otherwise the body controller continues to send the message until the RF signal receiving module replies.
具体的，上述过程可以通过车身控制器与射频信号接收模块之间通讯特定的报文一实现，该报文一的LIN报文ID为0xBA，该报文的作用如表1所示：Specifically, the foregoing process may be implemented by communicating a specific message between the body controller and the radio frequency signal receiving module. The LIN message ID of the message 1 is 0xBA, and the role of the message is as shown in Table 1:
表1Table 1
相应的，当+15节点线路打开时，车身控制器向射频信号接收模块发送报文以告知射频信号接收模块RKE停止工作，射频信号接收模块收到报文后向车身控制器发送反馈信息，告知已经收到，否则车身控制器继续发送报文，直到射频信号接收模块回复为止。Correspondingly, when the +15 node line is opened, the body controller sends a message to the radio frequency signal receiving module to inform the radio frequency signal receiving module RKE to stop working, and the radio frequency signal receiving module sends a feedback message to the body controller after receiving the message, to inform Already received, otherwise the body controller continues to send messages until the RF signal receiving module replies.

此外，车身控制器与射频信号接收模块之间的通讯信号还可以包括：In addition, the communication signal between the body controller and the RF signal receiving module may further include:
报文三，其LIN报文ID为0x39，如表3所示，报文三的信号主要实现射频信号的定义。由于射频信号接收模块的10个Byte中信息是经过加密的射频信号，本身杂乱无序，没有任何意义，无法给予详细的定义，至于RF On Response，只有1个bit是有效的，可以在文档中定义，如为1即RF Msg Valid即当前反馈帧为新接收到的有效帧，车身控制器应作出相应动作，如为0即RF Msg Invalid即当前反馈帧不是新接收到的帧，车身控制器可以忽略掉这帧数据。In message 3, the LIN message ID is 0x39. As shown in Table 3, the signal of message 3 mainly implements the definition of the radio frequency signal. Since the information in the 10 Bytes of the RF signal receiving module is an encrypted RF signal, it is disorderly and disorderly, and has no meaning and cannot be defined in detail. As for RF On Response, only 1 bit is valid and can be in the document. Definition, if 1 is RF Msg Valid, that is, the current feedback frame is the newly received valid frame, the body controller should make corresponding action, such as 0, ie RF Msg Invalid, ie the current feedback frame is not the newly received frame, the body controller This frame of data can be ignored.

具体的，如图2所示，射频信号接收模块向车身控制器发送的唤醒信号可以为250μs-5ms的显性电平。例如，当唤醒信号为250μs的显性电平时，LIN报文ID为在20Kbit/s波特率下的0x0F，当唤醒信号为5ms的显性电平时，LIN报文ID为在1Kbit/s波特率下的0x0F。
Specifically, as shown in FIG. 2, the wake-up signal sent by the radio frequency signal receiving module to the vehicle body controller may be a dominant level of 250 μs to 5 ms. For example, when the wake-up signal is at a dominant level of 250 μs, the LIN message ID is 0x0F at a 20 Kbit/s baud rate, and when the wake-up signal is at a dominant level of 5 ms, the LIN message ID is at 1 Kbit/s wave. 0x0F under the rate.
进一步的，当射频信号接收模块向车身控制器连续发送预设个数的唤醒信号，且未唤醒车身控制器时，射频信号接收模块等待预设时间后再次发送唤醒信号。Further, when the radio frequency signal receiving module continuously sends a preset number of wake-up signals to the vehicle body controller, and the vehicle body controller is not awake, the radio frequency signal receiving module waits for the preset time and then sends the wake-up signal again.
具体的，在图2所示的唤醒信号中，若LIN总线上有干扰等原因而使唤醒不成功，例如可以将预设个数定为3，预设时间定为1.5s，这样当射频信号接收模块向车身控制器连续发送3个的唤醒信号，且未唤醒车身控制器时，射频信号接收模块等待1.5s后再次发送唤醒信号。其中，预设个数与预设时间可以根据实际需要进行相应的设定，本发明实施例对此并不做限定。Specifically, in the wake-up signal shown in FIG. 2, if there is interference on the LIN bus, etc., the wakeup is unsuccessful. For example, the preset number can be set to 3, and the preset time is set to 1.5s, so that the RF signal is used. The receiving module continuously sends three wake-up signals to the body controller, and when the body controller is not awake, the RF signal receiving module waits for 1.5 seconds and then sends the wake-up signal again. The preset number and the preset time may be set according to actual needs, which is not limited by the embodiment of the present invention.
相应的，为了使得射频接收模块在非工作状态下处于睡眠状态，当车身控制器处于唤醒状态时，方法还可以包括：Correspondingly, in order to make the radio frequency receiving module be in a non-operating state, when the vehicle body controller is in the awake state, the method may further include:
当车身控制器处于唤醒状态，且没有收到射频接收模块发送信号的时间间隔大于等于睡眠时间阈值时，车身控制器向射频接收模块发送睡眠信号以使得射频接收模块进入睡眠状态。When the body controller is in the awake state and the time interval for not receiving the signal sent by the radio frequency receiving module is greater than or equal to the sleep time threshold, the body controller sends a sleep signal to the radio frequency receiving module to cause the radio frequency receiving module to enter a sleep state.
具体的，可以当从唤醒后1min内若没有收到射频接收模块的信号，则车身控制器发送一帧ID为0x3c的LIN报文，该报文可以形如图3所示，其中，第一个字节为零的主请求帧来使处于工作状态的射频信号接收模块进入睡眠。该帧报文即为睡眠信号，射频信号接收模块在接到睡眠信号之后即进入睡眠状态，或者，在接收到睡眠限号后射频信号接收模块也可以选择不进入睡眠状态而继续工作，具体可以根据应用层协议而定。在本发明实施例中，是以1min为睡眠时间阈值为例进行的说明，该时间阈值同样可以根据实际需要进行相应的设定，本发明实施例对此并不做限定。Specifically, if the signal of the radio frequency receiving module is not received within 1 min after waking up, the body controller sends a LIN message with a frame ID of 0x3c, and the message can be shaped as shown in FIG. 3, where the first A primary request frame with zero bytes to put the active RF signal receiving module into sleep. The frame message is a sleep signal, and the radio frequency signal receiving module enters a sleep state after receiving the sleep signal, or the radio frequency signal receiving module may choose not to enter the sleep state and continue to work after receiving the sleep limit number, specifically Depending on the application layer protocol. In the embodiment of the present invention, the description is made by taking the value of the sleep time threshold as an example. The time threshold is also set according to actual needs, which is not limited by the embodiment of the present invention.
进一步的，若射频接收模块没有接收到睡眠指令，且当总线空闲4s-10s时，同样可以设定射频接收模块必须进入睡眠状态。Further, if the radio frequency receiving module does not receive the sleep instruction, and when the bus is idle for 4s-10s, the radio receiving module must also be set to enter a sleep state.
需要说明的是，总线空闲的定义是指该总线上没有显性位和隐性位之间的转换。It should be noted that the definition of bus idle means that there is no conversion between dominant and recessive bits on the bus.
