In this application, the first low-frequency communication module installed at the entrance and exit of the road is used to send the first information to the on-board device of the vehicle within its low-frequency coverage through the low-frequency channel, and the first radio frequency communication module corresponding to the road receives the first information from the on-board device through the radio frequency. The second information returned by the channel according to the first information enables the management module to perform preset management on the vehicle according to the second information according to preset rules. In this process, the vehicle does not stop, but receives information through the low-frequency channel while driving. After receiving at least two second pieces of information, the first radio frequency communication module recognizes the vehicle's entry time point and departure time point according to the received second information, and calculates the parking time of the vehicle according to the time point, thereby charging. The charging process does not require manual participation. How the management module identifies the entry time point and the departure time point according to the second information will be described in detail in the following embodiments.
为使本发明的技术方案和优点更加清楚，下面通过具体实施方式结合附图对本发明作进一步详细说明。In order to make the technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.
请参考图3，在本申请中提供一种车辆管理装置10，其包括：设置在道路出入口的第一低频通信模块101、与所述道路对应的第一射频通信模块102，以及管理模块103。其中，第一低频通信模块101用于通过低频通道向道路上车辆的车载装置发送第一信息，具体为向驶过车辆的车载装置发送第一信息；第一射频通信模块102用于接收车载装置通过射频通道根据第一信息返回的第二信息；管理模块103用于按照预设规则根据第二信息对所述车辆进行预设管理。在图3中，只是以一个第一低频通信模块101进行说明，并没有限定第一低频通信模块101的个数，在本申请中，在收费区间中，各出入口都设置有相应的第一低频通信模块101，用于把该路段围城一个封闭的停车区间，而本申请的出入口可以指仅为出口或者仅为入口的单边道路，只需在对应的入口和出口设置相应的第一低频通信模块101。也可以为双向通行的道路，及该道路的入口也即是出口，在该处也可以设置对应的第一低频通信模块101。Please refer to FIG. 3 . This application provides a vehicle management device 10 , which includes: a first low-frequency communication module 101 installed at a road entrance, a first radio frequency communication module 102 corresponding to the road, and a management module 103 . Among them, the first low-frequency communication module 101 is used to send the first information to the vehicle-mounted device of the vehicle on the road through the low-frequency channel, specifically, to send the first information to the vehicle-mounted device passing the vehicle; the first radio frequency communication module 102 is used to receive the first information from the vehicle-mounted device The second information returned through the radio frequency channel according to the first information; the management module 103 is configured to perform preset management on the vehicle according to the second information according to preset rules. In Fig. 3, only one first low-frequency communication module 101 is used for illustration, and the number of first low-frequency communication modules 101 is not limited. In this application, in the toll interval, each entrance and exit is provided with a corresponding first low-frequency The communication module 101 is used to enclose the road section into a closed parking area, and the entrance and exit of this application can refer to only the exit or only the unilateral road of the entrance, only need to set the corresponding first low-frequency communication at the corresponding entrance and exit Module 101. It can also be a two-way road, and the entrance of the road is also the exit, where the corresponding first low-frequency communication module 101 can also be installed.
而具体的，在一个实施例中，第一低频通信模块101发送的第一信息可以为当：前时间信息；即车辆驶过该第一低频通信模块101的时间点信息。对应的第一射频通讯模块接收的第二信息包括：所述当前时间信息和车辆身份信息。车载装置除了将当前的时间信息发送给射频通道之外，还需要将车辆信息进行发送。从而使管理模块103获得车辆驶过该第一低频通信模块101的时间信息以及其车辆信息。Specifically, in one embodiment, the first information sent by the first low-frequency communication module 101 may be current time information; The second information received by the corresponding first radio frequency communication module includes: the current time information and vehicle identity information. In addition to sending the current time information to the radio frequency channel, the vehicle-mounted device also needs to send vehicle information. Thus, the management module 103 obtains the time information of the vehicle passing the first low-frequency communication module 101 and its vehicle information.
请参考图2，在本实施例中，管理模块103还包括：识别单元1031和交易单元1032；其中识别单元1031用于根据预设规则识别车辆驶入时间点和驶离时间点；交易单元1032用于根据驶入时间点和驶离时间点按照预设收费标准对车辆进行收费管理。在本实施例中，管理模块103中的识别单元1031对接收的两次不同的时间点信息的第二信息进行识别，获得车辆在该收费区间中的驶入时间点和驶离时间点，而交易单元1032获得两个时间点信息后，计算其在该收费区间中的时间段信息，并按照预设的收费标准对车辆进行收费。较优的，本实施例中，交易单元1032还可以通过设置一个允许时间段，该时间段应大于等于车辆在该收费区间内的标准行驶时间。交易模块将计算得到的时间段信息减去允许时间段之后得到车辆在该收费区间中实际停车时间，并根据该时间进行收费。具体的，本申请中交易模块对车辆进行收费的方式可以有很多种，例如，可以采用射频读卡的方式，修改车载装置中对应账户信息中相应的停车金额；也可以根据计算得到的停车金额，在后台用户存储的账户信息中进行修改，还可以将收费信息通过短信或者其他通知方式告知车主。Please refer to FIG. 2 , in this embodiment, the management module 103 also includes: an identification unit 1031 and a transaction unit 1032; wherein the identification unit 1031 is used to identify the vehicle entry time point and the departure time point according to preset rules; the transaction unit 1032 It is used to manage the charging of vehicles according to the preset charging standard according to the time point of entry and departure. In this embodiment, the identification unit 1031 in the management module 103 identifies the second information of the received two different time point information to obtain the entry time point and departure time point of the vehicle in the toll interval, and After obtaining the information of the two time points, the transaction unit 1032 calculates the time period information in the toll interval, and charges the vehicle according to the preset toll standard. Preferably, in this embodiment, the transaction unit 1032 can also set an allowable time period, which should be greater than or equal to the standard travel time of the vehicle within the toll interval. The transaction module subtracts the allowable time period from the calculated time period information to obtain the actual parking time of the vehicle in the charging interval, and charges according to this time. Specifically, there are many ways in which the transaction module can charge the vehicle in this application. For example, the radio frequency card reading method can be used to modify the corresponding parking amount in the corresponding account information in the vehicle-mounted device; it can also be based on the calculated parking amount. , modify the account information stored by the background user, and also inform the owner of the charging information through SMS or other notification methods.
在本申请一较优的实施例中，识别单元1031主要通过以下方式对车辆驶入时间点和驶离时间点进行识别：对接收的同一车载装置发送的第一个第二消息标记为未处理消息，并在接收该车载装置发送的第二个不同的第二消息时，将第一个第二消息中的当前时间信息作为驶入时间点，将第二个第二消息中的当前时间信息作为驶出时间点；并将两个第二消息标记为已处理消息。在该实施例中，识别单元1031通过标志位的方式来对进出时间点进行识别，具体的进出时间点为两个不同的时间点，所以识别单元1031只需要识别两个不同时间点的信息即可判断进出时间点，但为了排除将上一次的驶出时间作为本次驶入时间，而将本次驶入时间作为驶出时间。所以增加标志位，来标识一次收费操作，对两次时间点信息进行收费操作之后，将两个时间点对应的第二消息都标识为已处理消息，不再对该消息进行收费处理。而在下一次收到一个第二消息时，将该消息标记为未处理消息，并等待下次消息，将两个消息作为一次交易需要的数据，并将第一个第二消息中的当前时间信息作为驶入时间点，将第二个第二消息中的当前时间信息作为驶出时间点即可。In a preferred embodiment of the present application, the recognition unit 1031 mainly recognizes the time point when the vehicle enters and the time point when the vehicle departs in the following manner: mark the first and second messages received from the same vehicle-mounted device as unprocessed message, and when receiving a second different second message sent by the vehicle-mounted device, use the current time information in the first second message as the entry time point, and use the current time information in the second second message as the exit time point; and mark the two second messages as processed messages. In this embodiment, the identification unit 1031 identifies the entry and exit time points by means of flag bits. The specific entry and exit time points are two different time points, so the identification unit 1031 only needs to identify the information of two different time points, that is, The entry and exit time points can be judged, but in order to exclude the last entry time as the current entry time, the current entry time is used as the exit time. Therefore, a flag bit is added to identify a charging operation. After the charging operation is performed on the information of two time points, the second message corresponding to the two time points is marked as a processed message, and no charging process is performed on the message. When a second message is received next time, mark the message as an unprocessed message, and wait for the next message, use the two messages as the data required for a transaction, and store the current time information in the first second message As the entry time point, the current time information in the second second message may be used as the exit time point.
此外，在本申请另一实施例中，识别单元1031还可以通过以下方式对车辆驶入时间点和驶离时间点进行识别：识别单元1031判断在接收的两个不同的第二消息之间，第一射频模块是否一直都有收到车载装置返回的车辆身份信息或第二信息；若是，则将两个不同的第二信息中时间靠前的当前时间信息作为驶入时间点，将时间靠后的当前时间信息作为驶出时间点。此处的第一射频模块设置在收费区间内，其可以为一个或者多个，其一个或者多个第一射频模块的整体射频覆盖范围包括整个收费区间。在本实施例中，可以不对收到的信息进行标记，仅需要判断车辆在两个时间点之间是否一直都在停车区间内，这样的设置需要在整个停车区间内设置射频覆盖范围包括整个收费区间的多个第一射频通信模块102，而通过不停的读取车载装置的信息来判断车辆是否一直处于收费区间内。在本实施例中，除了在第一次收到第一信息之后，车载装置上传第二信息之外，后续的上传数据可以仅为车辆身份信息，当然也可以一直上传第二信息。而在车载单元下次经过第一低频通信模块101之前，第一射频通信模块102收到的第二信息都是同一个第二信息，里面的时间点信息相同。当第一射频通信模块102收到两个不同的第二信息之后，判断两个时间点之间，车辆是否一直处于收费区间，若是，则将两个不同的第二信息中时间靠前的当前时间信息作为驶入时间点，将时间靠后的当前时间信息作为驶出时间点。In addition, in another embodiment of the present application, the identification unit 1031 can also identify the time point when the vehicle enters and the time point when the vehicle leaves in the following manner: the identification unit 1031 judges that between two different second messages received, Whether the first radio frequency module has received the vehicle identity information or the second information returned by the vehicle-mounted device all the time; The latest current time information is used as the departure time point. Here, the first radio frequency module is set in the toll interval, and there may be one or more first radio frequency modules. The overall radio frequency coverage of one or more first radio frequency modules includes the entire toll interval. In this embodiment, the received information may not be marked, and it is only necessary to judge whether the vehicle has been in the parking area between two time points. Such a setting needs to set the radio frequency coverage in the entire parking area including the entire charging Multiple first radio frequency communication modules 102 in the interval, and judge whether the vehicle has been in the toll interval by continuously reading the information of the vehicle-mounted device.

而具体的，在一个实施例中，第一低频通信模块101发送的第一信息可以为当：前时间信息；即车辆驶过该第一低频通信模块101的时间点信息。Specifically, in one embodiment, the first information sent by the first low-frequency communication module 101 may be current time information;
步骤506：与道路对应的第一射频通信模块接收车载装置通过射频通道根据第一信息返回的第二信息；进入步骤506；Step 506: The first radio frequency communication module corresponding to the road receives the second information returned by the vehicle-mounted device through the radio frequency channel according to the first information; enter step 506;
在本步骤中，由第一射频通信模块102负责接收车载装置通过射频通道根据第一信息返回的第二信息。一实施例中，第一射频通讯模块接收的第二信息包括：所述当前时间信息和车辆身份信息。车载装置除了将当前的时间信息发送给射频通道之外，还需要将车辆信息进行发送。从而使管理模块103获得车辆驶过该第一低频通信模块101的时间信息以及其车辆身份信息。In this step, the first radio frequency communication module 102 is responsible for receiving the second information returned by the vehicle-mounted device through the radio frequency channel according to the first information.

步骤508：管理模块按照预设规则根据第二信息对所述车辆进行预设管理。Step 508: The management module performs preset management on the vehicle according to the second information according to preset rules.
在本实施例中，由管理模块103根据接收的第二信息对车辆进行管理，该管理可以有多种形式，如记录车辆的车辆信息，提供用户查询功能，或者对车辆进行停车收费等功能，而具体的，请参考图6，本申请中的步骤508，还可以具体包括步骤5081和步骤5082；In this embodiment, the management module 103 manages the vehicle according to the received second information. The management can take various forms, such as recording the vehicle information of the vehicle, providing a user query function, or charging the vehicle for parking, etc. Specifically, please refer to FIG. 6, step 508 in this application may also specifically include step 5081 and step 5082;
步骤5081：根据预设规则识别车辆驶入时间点和驶离时间点；进入步骤5082；Step 5081: Identify the vehicle entry time point and departure time point according to preset rules; enter step 5082;
在本步骤中，由识别单元根据第二信息识别车辆的驶入时间点和驶离时间点，具体可以采用下面的方式：In this step, the recognition unit recognizes the entry time point and the departure time point of the vehicle according to the second information. Specifically, the following methods can be used:
对接收的同一车载装置发送的第一个第二消息标记为未处理消息，并在接收该车载装置发送的第二个不同的第二消息时，将第一个第二消息中的当前时间信息作为驶入时间点，将第二个第二消息中的当前时间信息作为驶出时间点；并将两个第二消息标记为已处理消息。在该实施例中，识别单元1031通过标志位的方式来对进出时间点进行识别，具体的进出时间点为两个不同的时间点，所以识别单元1031只需要识别两个不同时间点的信息即可判断进出时间点，但为了排除将上一次的驶出时间作为本次驶入时间，而将本次驶入时间作为驶出时间。所以增加标志位，来标识一次收费操作，对两次时间点信息进行收费操作之后，将两个时间点对应的第二消息都标识为已处理消息，不再对该消息进行收费处理。而在下一次收到一个第二消息时，将该消息标记为未处理消息，并等待下次消息，将两个消息作为一次交易需要的数据，并将第一个第二消息中的当前时间信息作为驶入时间点，将第二个第二消息中的当前时间信息作为驶出时间点即可。Mark the first second message sent by the same vehicle-mounted device as an unprocessed message, and when receiving a second different second message sent by the vehicle-mounted device, the current time information in the first second message As the entry time point, the current time information in the second second message is used as the exit time point; and the two second messages are marked as processed messages. In this embodiment, the identification unit 1031 identifies the entry and exit time points by means of flag bits. The specific entry and exit time points are two different time points, so the identification unit 1031 only needs to identify the information of two different time points, that is, The entry and exit time points can be judged, but in order to exclude the last entry time as the current entry time, the current entry time is used as the exit time. Therefore, a flag bit is added to identify a charging operation. After the charging operation is performed on the information of two time points, the second message corresponding to the two time points is marked as a processed message, and no charging process is performed on the message. When a second message is received next time, mark the message as an unprocessed message, and wait for the next message, use the two messages as the data required for a transaction, and store the current time information in the first second message As the entry time point, the current time information in the second second message may be used as the exit time point.
此外，在本申请另一实施例中，识别单元1031还可以通过以下方式对车辆驶入时间点和驶离时间点进行识别：识别单元1031判断在接收的两个不同的第二消息之间，第一射频模块是否一直都有收到车载装置返回的车辆身份信息或第二信息；若是，则将两个不同的第二信息中时间靠前的当前时间信息作为驶入时间点，将时间靠后的当前时间信息作为驶出时间点。此处的第一射频模块设置在收费区间内，其可以为一个或者多个，其一个或者多个第一射频模块的整体射频覆盖范围包括整个收费区间。在本实施例中，可以不对收到的信息进行标记，仅需要判断车辆在两个时间点之间是否一直都在停车区间内，这样的设置需要在整个停车区间内设置射频覆盖范围包括整个收费区间的多个第一射频通信模块102，而通过不停的读取车载装置的信息来判断车辆是否一直处于收费区间内。在本实施例中，除了在第一次收到第一信息之后，车载装置上传第二信息之外，后续的上传数据可以仅为车辆身份信息，当然也可以一直上传第二信息。而在车载单元下次经过第一低频通信模块101之前，第一射频通信模块102收到的第二信息都是同一个第二信息，里面的时间点信息相同。当第一射频通信模块102收到两个不同的第二信息之后，判断两个时间点之间，车辆是否一直处于收费区间，若是，则将两个不同的第二信息中时间靠前的当前时间信息作为驶入时间点，将时间靠后的当前时间信息作为驶出时间点。In addition, in another embodiment of the present application, the identification unit 1031 can also identify the time point when the vehicle enters and the time point when the vehicle leaves in the following manner: the identification unit 1031 judges that between two different second messages received, Whether the first radio frequency module has received the vehicle identity information or the second information returned by the vehicle-mounted device all the time; The latest current time information is used as the departure time point. Here, the first radio frequency module is set in the toll interval, and there may be one or more first radio frequency modules. The overall radio frequency coverage of one or more first radio frequency modules includes the entire toll interval. In this embodiment, the received information may not be marked, and it is only necessary to judge whether the vehicle has been in the parking area between two time points. Such a setting needs to set the radio frequency coverage in the entire parking area including the entire charging Multiple first radio frequency communication modules 102 in the interval, and judge whether the vehicle has been in the toll interval by continuously reading the information of the vehicle-mounted device. In this embodiment, except that the vehicle-mounted device uploads the second information after receiving the first information for the first time, the subsequent upload data may be only the vehicle identity information, and of course, the second information may also be uploaded all the time. Before the vehicle-mounted unit passes the first low-frequency communication module 101 next time, the second information received by the first radio frequency communication module 102 is the same second information, and the time point information in it is the same. After the first radio frequency communication module 102 receives two different second messages, it is judged whether the vehicle has been in the toll zone between two time points, and if so, the current time earlier in the two different second messages is The time information is used as the entry time point, and the current time information with a later time is used as the exit time point.
此外，本申请中，还提供另外一种识别车辆驶入时间点和驶离时间点的方式：在第一信息和第二信息中还包括：与第一信息对应的第一低频通信模块101的标识信息。而识别单元1031则根据接收的同一车辆两个相邻且当前时间信息不同的第二信息中第一低频通信模块101的标识信息，识别车辆进出的出入口，并将进出口为入口且时间靠前的当前时间信息作为驶入时间点，将进出口为出口且时间靠后的当前时间信息作为驶出时间点。在本实施例中，第一低频通信模块101发送的第一信息以及车载终端返回的第二信息中还带有第一低频通信模块101自身的标识信息，管理模块103通过提取该标识信息，判断第一低频通信模块101对应的是出口还是入口，若为入口，而且其时间在接收的两个时间点中为靠前的时间点，则将该时间点作为驶入时间点；若识别该标识信息为出口标识，且对应的时间点信息为两个时间点中靠后的时间点，则将该时间点作为驶出时间点。本实施例中的识别方式适用于出口和入口分开设置的路段。In addition, in this application, another way of identifying the time point of vehicle entry and departure is provided: the first information and the second information also include: the first low-frequency communication module 101 corresponding to the first information Identification information. The identification unit 1031 identifies the entrance and exit of the vehicle according to the identification information of the first low-frequency communication module 101 in the received second information of two adjacent and different current time information of the same vehicle, and regards the entrance and exit as the entrance and the time is earlier. The current time information of is used as the entry time point, and the current time information with the import and export as the exit and later time is used as the exit time point. In this embodiment, the first information sent by the first low-frequency communication module 101 and the second information returned by the vehicle-mounted terminal also include the identification information of the first low-frequency communication module 101 itself, and the management module 103 judges by extracting the identification information Whether the first low-frequency communication module 101 corresponds to an exit or an entrance, if it is an entrance, and its time is the earlier time point in the two received time points, then this time point is used as the time point of entry; if the identification is identified If the information is an exit sign, and the corresponding time point information is the later time point of the two time points, then this time point is taken as the exit time point. The identification method in this embodiment is applicable to road sections where exits and entrances are set separately.
步骤5082：根据驶入时间点和驶离时间点按照预设收费标准对车辆进行收费管理。Step 5082: Carry out charging management for the vehicle according to the preset charging standard according to the time point of entry and departure.
在本步骤中，由交易单元1032根据驶入时间点和驶离时间点按照预设收费标准对车辆进行收费管理。较优的，本实施例中，交易单元1032还可以通过设置一个允许时间段，该时间段应大于等于车辆在该收费区间内的标准行驶时间。交易模块将计算得到的时间段信息减去允许时间段之后得到车辆在该收费区间中实际停车时间，并根据该时间进行收费。具体的，本申请中交易模块对车辆进行收费的方式可以有很多种，例如，可以采用射频读卡的方式，修改车载装置中对应账户信息中相应的停车金额；也可以根据计算得到的停车金额，在后台用户存储的账户信息中进行修改，还可以将收费信息通过短信或者其他通知方式告知车主。In this step, the transaction unit 1032 manages the charging of the vehicle according to the preset charging standard according to the driving-in time point and the driving-out time point. Preferably, in this embodiment, the transaction unit 1032 can also set an allowable time period, which should be greater than or equal to the standard travel time of the vehicle within the toll interval. The transaction module subtracts the allowable time period from the calculated time period information to obtain the actual parking time of the vehicle in the charging interval, and charges according to this time. Specifically, there are many ways in which the transaction module can charge the vehicle in this application. For example, the radio frequency card reading method can be used to modify the corresponding parking amount in the corresponding account information in the vehicle-mounted device; it can also be based on the calculated parking amount. , modify the account information stored by the background user, and also inform the owner of the charging information through SMS or other notification methods.
