Abstract

Disclosed are a collision detection method, a magnetic radio frequency device and a communication system. A first magnetic radio frequency device performs magnetic communication access with a second magnetic radio frequency device using a magnetic channel; and the first magnetic radio frequency device further emits a collision detection request signal via the magnetic channel and judges whether there are a plurality of second magnetic radio frequency devices colliding with each other according to whether a response signal of the collision detection request signal is received or according to the received response signal. During the whole process of collision detection, the interaction between relevant instructions is performed via the magnetic channel without the participation of a radio frequency module and independent of a radio frequency channel, so the radio frequency interaction time will not be affected, improving the communication efficiency of the first magnetic radio frequency device and the second magnetic radio frequency device to a certain extent; furthermore, the situation where relevant instructions for detecting collisions on the radio frequency channel interfere with the application data can be avoided, thus the accuracy of collision detection results and the reliability of radio frequency communication can be improved.

This RF data exchange method has been widely used in many fields such as electronic wallet payment, bus credit card printing and the like.
在磁通信为单向通信的射频通信***中，作为第一磁射频装置的读卡器发送磁信息，作为第二磁射频装置的装在手机的SIM卡或SD卡通过检测耦合到的磁信号强度及接收磁信息，来激活SIM卡或SD卡上的射频通信模块，以便进行射频接入。在接入完成后，第一磁射频装置在磁信道上发送冲突检测请求，以检测是否有多个第二磁射频装置相冲突，并周期性地在射频信道上查询接收是否有冲突响应。假设此时有两个第二磁射频装置A和B相冲突，其中第二磁射频装置A已与第一磁射频装置完成接入，因此第二磁射频装置A接收到该冲突检测请求时，忽略该冲突检测请求；而第二磁射频装置B未与第一射频装置建立连接，因此第二磁射频装置B接收到该冲突检测请求时，认为发生了冲突，在射频信道上回复冲突响应。In a radio frequency communication system in which magnetic communication is one-way communication, a card reader as a first magnetic radio frequency device transmits magnetic information, and a SIM card or an SD card mounted on a mobile phone as a second magnetic radio frequency device detects a coupled magnetic signal. Intensity and receiving magnetic information to activate the RF communication module on the SIM card or SD card for RF access. After the access is completed, the first magnetic radio frequency device transmits a collision detection request on the magnetic channel to detect whether there are multiple second magnetic radio frequency devices colliding, and periodically polls the radio frequency channel for whether the reception has a conflict response. Suppose that there are two second magnetic RF devices A and B colliding at this time, wherein the second magnetic RF device A has completed access with the first magnetic RF device, so when the second magnetic RF device A receives the conflict detection request, The conflict detection request is ignored; and the second magnetic radio device B does not establish a connection with the first radio frequency device. Therefore, when the second magnetic radio device B receives the collision detection request, it considers that a collision has occurred and replies a collision response on the radio frequency channel.
由上可见，在磁通信为单向通信的射频通信***中，采用的冲突检测方法，冲突的检测必须是在建立好射频通信连接后进行的，冲突响应通过射频信道进行反馈，第一磁射频装置则需周期性地在射频信道上查询是否有接收到冲突响应，从而占用了射频通信资源和正常的射频交互时间，且易对射频通道上的其他应用数据的传送造成干扰，导致第一磁射频装置与第二磁射频装置进行刷卡交易的时间变长的同时，降低了冲突检测结果的准确率和射频通信的可靠性。It can be seen from the above that in the radio communication system in which the magnetic communication is one-way communication, the conflict detection method is adopted, and the collision detection must be performed after the RF communication connection is established, and the conflict response is fed back through the radio frequency channel, the first magnetic RF The device needs to periodically check whether the radio frequency channel receives the conflict response, thereby occupying the radio frequency communication resource and the normal radio frequency interaction time, and easily causing interference to the transmission of other application data on the radio frequency channel, resulting in the first magnetic field. The time for the RF device and the second magnetic RF device to perform the card transaction becomes longer, and the accuracy of the conflict detection result and the reliability of the RF communication are reduced.

第二处理子模块212接收到第二磁信号接收子模块213发送的身份认证请求信息后，对其进行处理生成身份认证响应信息，并通过第二磁信号发送子模块214发送出去，以与发送该请求信息的第一磁射频装置建立磁通信接入，也即第一磁射频装置约定与该第二磁射频装置进行通信；还用于接收到第二磁信号接收子模块213发送的冲突检测请求信号后，根据预设规则判断是否通过第二磁信号发送子模块214向发送该冲突检测请求信号的第一磁射频装置反馈冲突检测请求的响应信号。After receiving the identity authentication request information sent by the second magnetic signal receiving sub-module 213, the second processing sub-module 212 processes the identity authentication response information, and sends the identity authentication response information to the second magnetic signal transmitting sub-module 214 for transmission and transmission. The first magnetic radio frequency device of the request information establishes a magnetic communication access, that is, the first magnetic radio frequency device agrees to communicate with the second magnetic radio frequency device; and is further configured to receive the conflict detection sent by the second magnetic signal receiving sub-module 213 After the signal is requested, it is determined according to a preset rule whether the response signal of the collision detection request is fed back to the first magnetic RF device that transmits the collision detection request signal by the second magnetic signal transmission sub-module 214.
在本实施例中，该预设规则可为：接收到的冲突检测请求信号是与自身进行磁通信连接的第一磁射频装置发送的时，不发送该冲突检测请求的响应信号；否则，发送该冲突检测请求的响应信号。此时，第二处理子模块212判断是否向发送冲突检测请求的第一磁射频装置反馈响应消息则包括：判断该第一磁射频装置是否与自身进行磁通信连接，具体为：判断接收到的冲突检测请求信号包括的身份信息（该身份信息是第一磁信号产生子模块111所添加的）是否与自身的身份信息相匹配，如匹配，判断为该冲突检测请求信号是与自身磁通信连接的第一磁射频装置发送的；否则，判断为该冲突检测请求信号不是与自身磁通信连接的第一磁射频装置发送的。在判断出冲突检测请求信号不是与自身磁通信连接的第一磁射频装置发送时，第二处理子模块212不向发送请求消息的第一磁射频装置反馈冲突检测请求的响应消息；否则，向发送请求消息的第一磁射频装置反馈冲突检测请求的响应消息。In this embodiment, the preset rule may be: when the received conflict detection request signal is sent by the first magnetic radio frequency device that is in magnetic communication connection with itself, the response signal of the conflict detection request is not sent; otherwise, the sending The response signal of the conflict detection request. At this time, the second processing sub-module 212 determining whether to feed back the response message to the first magnetic RF device that sends the conflict detection request includes: determining whether the first magnetic RF device is in magnetic communication connection with itself, specifically: determining the received Whether the identity information included in the conflict detection request signal (which is added by the first magnetic signal generating sub-module 111) matches the identity information of the self, and if the matching is matched, it is determined that the conflict detection request signal is connected to the magnetic communication itself.

基于上述预设规则，第一磁射频装置的第一处理子模块112则根据第一磁信号接收子模块114是否接收到第二磁射频装置反馈的冲突检测请求信号的响应信号判断是否存在相冲突的第二磁射频装置；因为基于上述预设原则，如果接收到冲突检测请求的响应消息，则该响应消息一定不是与自身磁通信接入的第二磁射频装置反馈的，因此一定存在相冲突的第二磁射频装置；具体判断过程如下：The first processing sub-module 112 of the first magnetic radio frequency device determines whether there is a conflict according to whether the first magnetic signal receiving sub-module 114 receives the response signal of the conflict detection request signal fed back by the second magnetic radio frequency device. The second magnetic radio frequency device; because based on the above preset principle, if the response message of the conflict detection request is received, the response message must not be fed back with the second magnetic RF device accessed by its own magnetic communication, so there must be a conflict The second magnetic RF device; the specific judgment process is as follows:

Different identity information, if any, that is, other second magnetic RF devices are determined to have conflicting second magnetic RF devices within the effective communication distance of the first magnetic RF device; otherwise, it is determined that there is no conflict The second magnetic radio frequency device can directly establish a radio frequency communication connection with the second magnetic radio frequency device, specifically, the first processing sub-module 112 sends the first magnetic signal when it is determined that there is no conflicting second magnetic radio frequency device The sub-module 114 sends a radio frequency communication connection request message to the second magnetic radio frequency device connected to the magnetic communication for radio frequency communication connection therewith.
为了更好的理解本发明，本发明的另一实施例中以更为具体的例子做进一步的说明。In order to better understand the present invention, another embodiment of the present invention will be further described in more specific examples.
本实施例中，第一磁射频装置1可以为读卡器件；第二磁射频装置2可以是置于移动终端中或者置于移动终端内的各种射频卡，例如可为射频SIM卡、射频UIM卡、射频USIM卡、射频TF卡或射频SD卡中，其中，所述移动终端是指可以移动的终端，可以是手机、个人数字助理PDA或者笔记本电脑等。此处的读卡器件和射频SIM卡、射频UIM卡、射频USIM卡、射频TF卡或射频SD卡都具有上述磁通信模块和射频通信模块。请参见图5，该图所示的通信***包括一个第一磁射频装置1和两个第二磁射频装置2，两个第二磁射频装置2都在第一磁射频装置1的有效通信距离内。第一磁射频装置1发射磁信息，第二磁射频装置2通过检测耦合到的磁信号强度而接收磁信息，并对接收到的磁信息解析后通过磁信道发送反馈信息至第一磁射频装置100，以使得准备进行射频通信的双方在接入射频通信前利用磁场信号进行双向通信而确定通信双方的身份合法，即完成磁通信接入。但是，由于磁信号强度是在空间中传播的，因此，如果在第一磁射频装置1的有效通信范围内同时聚集了多个第二磁射频装置时，将会导致无法判断哪一个第二磁射频装置被第一磁射频装置100感应到并将与其进行射频数据交互，这种情况就是本发明中的冲突；如图5中的两个第二磁射频装置都在第一磁射频装置1的有效通信范围内，则持有第二磁射频装置2和持有第二磁射频装置3的两位用户将无法判断到底是哪一个第二磁射频装置被第一磁射频装置1感应到并将与其进行交易。In this embodiment, the first magnetic radio frequency device 1 may be a card reading device; the second magnetic radio frequency device 2 may be a radio frequency card placed in the mobile terminal or placed in the mobile terminal, for example, a radio frequency SIM card, a radio frequency The UIM card, the radio frequency USIM card, the radio frequency TF card or the radio frequency SD card, wherein the mobile terminal refers to a mobile terminal, which may be a mobile phone, a personal digital assistant PDA or a notebook computer. The card reading device and the radio frequency SIM card, the radio frequency UIM card, the radio frequency USIM card, the radio frequency TF card or the radio frequency SD card have the above-mentioned magnetic communication module and radio frequency communication module. Referring to FIG. 5, the communication system shown in the figure includes a first magnetic RF device 1 and two second magnetic RF devices 2, and the two second magnetic RF devices 2 have effective communication distances at the first magnetic RF device 1. Inside. The first magnetic RF device 1 transmits magnetic information, and the second magnetic RF device 2 receives magnetic information by detecting the intensity of the coupled magnetic signal, and parses the received magnetic information and sends feedback information to the first magnetic RF device through the magnetic channel. 100, so that both parties preparing to perform radio frequency communication use the magnetic field signal to perform two-way communication before accessing the radio frequency communication to determine the identity of the two communication parties, that is, complete the magnetic communication access. However, since the magnetic signal strength propagates in space, if a plurality of second magnetic RF devices are simultaneously collected within the effective communication range of the first magnetic RF device 1, it will be impossible to determine which second magnetic The radio frequency device is sensed by the first magnetic radio frequency device 100 and will interact with the radio frequency data, which is a conflict in the present invention; as shown in FIG. 5, the two second magnetic radio devices are all in the first magnetic radio device 1 Within the effective communication range, the two users holding the second magnetic RF device 2 and holding the second magnetic RF device 3 will not be able to determine which second magnetic RF device is sensed by the first magnetic RF device 1 and will Trade with it.
为了解决上述技术问题，设第一磁射频装置1与第二磁射频装置2之间利用磁双向通信进行身份确认，完成磁通信接入；然后在第一磁射频装置1与第二磁射频装置2之间建立射频通信前，第一磁射频装置1通过磁信道发射冲突检测请求信号，并根据通过磁信道是否接收到冲突检测请求信号的响应信号或根据接收到的冲突检测请求信号的响应信号判断是否有多个第二磁射频装置相冲突；如果第一磁射频装置1在检测到冲突后，将与已建立磁通信连接的第二磁射频装置2断开连接，停止交易，以避免因用户无法判断是哪一个第二磁射频装置被感应并交易而产生的损失。In order to solve the above technical problem, it is assumed that the first magnetic RF device 1 and the second magnetic RF device 2 use the magnetic two-way communication for identity confirmation to complete the magnetic communication access; and then the first magnetic RF device 1 and the second magnetic RF device Before establishing the radio frequency communication between the two, the first magnetic radio frequency device 1 transmits the collision detection request signal through the magnetic channel, and according to whether the response signal of the collision detection request signal is received through the magnetic channel or the response signal according to the received collision detection request signal Determining whether there are multiple second magnetic RF devices colliding; if the first magnetic RF device 1 detects a conflict, disconnecting the second magnetic RF device 2 that has established the magnetic communication connection, stopping the transaction to avoid the cause The user cannot determine which of the second magnetic RF devices is sensed and traded for loss.
另外需要说明的是，第二磁射频装置2与第二磁射频装置3在结构、资源上可以是对等的，可以认为是两个功能完全相同的装置，只是各自的持有人不同而已。请参见图6，上述过程具体如下：It should be noted that the second magnetic RF device 2 and the second magnetic RF device 3 may be equivalent in structure and resources, and may be considered as two devices having the same function, but the respective holders are different. Referring to Figure 6, the above process is as follows:
步骤601：图5中第一磁射频装置1与第二磁射频装置2建立磁通信接入，具体为：Step 601: In FIG. 5, the first magnetic RF device 1 and the second magnetic RF device 2 establish magnetic communication access, specifically:
步骤6011：第一磁射频装置1的第一磁信号产生子模块111生成身份认证请求信息，通过第一磁信号发送模块114发送给第二磁射频装置2；Step 6011: The first magnetic signal generating sub-module 111 of the first magnetic RF device 1 generates identity authentication request information, and is sent to the second magnetic RF device 2 through the first magnetic signal transmitting module 114;
步骤6012：第二磁射频装置2的第二磁信号接收子模块213接收来自第一磁射频装置1的身份认证请求信息，并将其发送给第二处理子模块212，第二处理子模块212接收到第二磁信号接收子模块213发送的身份认证请求信息后，对其进行处理生成身份认证响应信息，并通过第二磁信号发送子模块214发送给第一磁射频装置1；Step 6012: The second magnetic signal receiving sub-module 213 of the second magnetic radio frequency device 2 receives the identity authentication request information from the first magnetic radio frequency device 1 and sends it to the second processing sub-module 212. The second processing sub-module 212 After receiving the identity authentication request information sent by the second magnetic signal receiving sub-module 213, it is processed to generate identity authentication response information, and sent to the first magnetic RF device 1 through the second magnetic signal transmitting sub-module 214;
步骤6013：第一磁射频装置1的第一磁信号接收到模块113接收到该响应消息后，将其发送给第一处理子模块112，完成与第二磁射频装置2的磁通信接入。Step 6013: After receiving the response message, the first magnetic signal receiving module 113 of the first magnetic RF device 1 sends the response message to the first processing sub-module 112 to complete the magnetic communication access with the second magnetic RF device 2.
步骤602：第一磁射频装置1通过双向通信的磁信道发射冲突检测请求信号，具体为：Step 602: The first magnetic radio frequency device 1 transmits a collision detection request signal by using a magnetic channel of two-way communication, specifically:
第一磁射频装置1的第一磁信号产生子模块111接收到第一处理子模块112发送的磁接入成功消息后，生成冲突检测请求信号，通过第一磁信号发送子模块113发送出去。After receiving the magnetic access success message sent by the first processing sub-module 112, the first magnetic signal generating sub-module 111 of the first magnetic radio frequency device 1 generates a collision detection request signal, which is sent by the first magnetic signal transmitting sub-module 113.
步骤603：第二磁射频装置2通过磁信道接收到第一磁射频装置1冲突检测请求信号，根据预设规则判断是否向第一磁射频装置1反馈响应信号；Step 603: The second magnetic RF device 2 receives the first magnetic RF device 1 collision detection request signal through the magnetic channel, and determines whether to feed back the response signal to the first magnetic RF device 1 according to a preset rule.
由于第二磁射频装置2和第二磁射频装置3都处于第一磁射频装置1的有效交易距离内，因此第二磁射频装置2和第二磁射频装置3的第二磁信号接收到模块213都会接收到冲突检测请求信号并将其发送给相应的第二处理子模块212；第二处理子模块212则可根据预设规则判断是否反馈响应信号。为了提高资源的利用率，简化方案，本实施例中可优选预设规则为：接收到的冲突检测请求信号是与自身磁通信连接的第一磁射频装置发送的时，不发送所述冲突检测请求的响应信号；否则，发送所述冲突检测请求的响应信号。此时，第二处理子模块212根据第一磁射频装置1是否与自身对应的第二磁射频装置2磁通信接入判断是否反馈响应信号。Since both the second magnetic RF device 2 and the second magnetic RF device 3 are within the effective transaction distance of the first magnetic RF device 1, the second magnetic signals of the second magnetic RF device 2 and the second magnetic RF device 3 are received by the module. The 213 will receive the conflict detection request signal and send it to the corresponding second processing sub-module 212. The second processing sub-module 212 can determine whether to feed back the response signal according to a preset rule. In order to improve the utilization of resources and simplify the solution, in this embodiment, the preset rule may be: when the received conflict detection request signal is sent by the first magnetic radio frequency device connected to its own magnetic communication, the conflict detection is not sent. The requested response signal; otherwise, the response signal of the conflict detection request is sent. At this time, the second processing sub-module 212 determines whether to feed back the response signal according to whether the first magnetic RF device 1 is in magnetic communication with the second magnetic RF device 2 corresponding to itself.
步骤604：第一磁射频装置1通过磁信道判断是否接收到冲突检测请求的响应信号，如是，转至步骤605；否则，转至步骤606；Step 604: The first magnetic RF device 1 determines whether the response signal of the conflict detection request is received through the magnetic channel, and if so, proceeds to step 605; otherwise, proceeds to step 606;
第二磁射频装置2的第二处理子模块212判断出第一磁射频装置1是与自身磁通信接入的第一磁射频装置1，因此不反馈响应信号；而第二磁射频装置3的第二处理子模块212判断出第一磁射频装置1未与自身磁通信接入，因此通过磁通道向第一磁射频装置1反馈响应信号。The second processing sub-module 212 of the second magnetic RF device 2 determines that the first magnetic RF device 1 is the first magnetic RF device 1 that is in magnetic communication with itself, and therefore does not feed back the response signal; and the second magnetic RF device 3 The second processing sub-module 212 determines that the first magnetic RF device 1 is not in magnetic communication with itself, and therefore feeds back a response signal to the first magnetic RF device 1 through the magnetic channel.
步骤605：第一磁射频装置1断开与第二磁射频装置2之间的磁通信连接；然后还可进行重复的进行上述连接、检测的过程，直到检测到没有相冲突的第二磁射频装置为止。Step 605: The first magnetic RF device 1 disconnects the magnetic communication connection with the second magnetic RF device 2; then, the process of repeatedly performing the above connection and detection may be performed until it is detected that there is no conflicting second magnetic RF Until the device.
步骤606：第一磁射频装置1建立与第二磁射频装置2之间的射频通信连接。Step 606: The first magnetic RF device 1 establishes a radio frequency communication connection with the second magnetic RF device 2.
由上可见，本发明中的第一磁射频装置和第二磁射频装置之间在进行冲突检测的过程中，与冲突检测相关的指令都是通过磁信道进行的交互的，并不需要射频模块参与，也并不依赖于射频通道，因此不会影响射频交互的时间，在一定程度上提高了第一磁射频装置和第二磁射频装置的通信效率；还可避免现有技术中射频通道上的应用数据与冲突检测的相关指令相互相互干扰的情况发生，可提升冲突检测结果的准确率和射频通信的可靠性。It can be seen that, in the process of performing collision detection between the first magnetic radio frequency device and the second magnetic radio frequency device in the present invention, the instructions related to the collision detection are all interacted by the magnetic channel, and the radio frequency module is not needed. Participation does not depend on the RF channel, so it does not affect the time of RF interaction, and improves the communication efficiency of the first magnetic RF device and the second magnetic RF device to some extent. It can also avoid the RF channel in the prior art. The application data and the conflict detection related instructions interfere with each other, which can improve the accuracy of the conflict detection result and the reliability of the radio communication.
