The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to be used to explain the present invention, but should not be construed as a limitation of the present invention. Based on the embodiments of the present invention, those of ordinary skill in the art will not make any creative work. All other embodiments obtained under the premise belong to the protection scope of the present invention.
本发明提出一种基于无线局域网的通信方法，应用于由无线局域网设备以及多个移动终端构建的无线局域网系统，其中无线局域网设备可以是无线路由器，如图1所示，该通信方法包括：The present invention proposes a communication method based on a wireless local area network, which is applied to a wireless local area network system constructed by a wireless local area network device and a plurality of mobile terminals, wherein the wireless local area network device may be a wireless router, as shown in FIG. 1 , the communication method includes:
步骤S10A，第一移动终端开启UDP协议并向无线局域网设备发送接收地址为预设地址的广播包。Step S10A, the first mobile terminal enables the UDP protocol and sends a broadcast packet whose receiving address is a preset address to the wireless local area network device.
本步骤中，开启UDP协议的方式可以是用户在第一移动终端的软件上进行启动，当然也可以是UDP协议处于常开状态，在需要进行通信时，用户直接在软件上输入预设地址后即可自动生成广播包。其中广播包的内容可以是第一移动终端的特定编号。In this step, the way of enabling the UDP protocol may be that the user starts the software on the first mobile terminal, and of course, the UDP protocol may also be in a normally open state. When communication is required, the user directly enters the preset address on the software after The broadcast package can be automatically generated. The content of the broadcast packet may be the specific number of the first mobile terminal.
步骤S20A，第一移动终端接收由第二移动终端发送的应答包，并根据所接收的应答包与第二移动终端建立通信通道。Step S20A, the first mobile terminal receives the response packet sent by the second mobile terminal, and establishes a communication channel with the second mobile terminal according to the received response packet.
本步骤中，第一移动终端接收第二移动终端(即无线局域网内除第一移动终端外的所有移动终端)发送应答包并识别该应答包内的信息，然后根据该信息与第二移动终端建立通信通道，从而第一移动终端与第二移动终端即可通过通信通道进行通信。其中，第一移动终端接收无线局域网发送的应答包，具体数据传输的方式参照现有局域网传输数据的形式进行即可。In this step, the first mobile terminal receives a response packet sent by the second mobile terminal (that is, all mobile terminals in the wireless local area network except the first mobile terminal) and identifies the information in the response packet, and then communicates with the second mobile terminal according to the information. A communication channel is established, so that the first mobile terminal and the second mobile terminal can communicate through the communication channel. The first mobile terminal receives the response packet sent by the wireless local area network, and the specific data transmission method may refer to the existing local area network data transmission form.
本实施例中，通过将多个智能设备在无线局域网内建立通信通道，以此即可利用通信通道进行数据传输，由于该数据传输仅在无线局域网内进行，因此并不需要产生费用，从而有利于降低短距离的通信成本。同时现有的无线路由器的覆盖范围以及数据传输速度不断提高，因此该通信方法特别适用企业内部通信。In this embodiment, by establishing a communication channel in the wireless local area network with a plurality of smart devices, the communication channel can be used for data transmission. Conducive to reducing the cost of short-distance communication. At the same time, the coverage and data transmission speed of the existing wireless routers are continuously improved, so the communication method is especially suitable for the internal communication of enterprises.
在一较佳实施例中，第一移动终端开启UDP协议并向无线局域网设备发送接收地址为预设地址的广播包的步骤包括：In a preferred embodiment, the step of the first mobile terminal enabling the UDP protocol and sending a broadcast packet whose receiving address is a preset address to the wireless local area network device includes:
生成含有第一移动终端IP地址的广播包；generating a broadcast packet containing the IP address of the first mobile terminal;
获取预设的公共地址；Get the default public address;
向公共地址发送广播包。Send a broadcast packet to the public address.
本步骤中，由于每个移动终端连入无线局域网后均会得到一个特定的IP地址，因此第一移动终端可在生成广播包时，将第一终端的IP地址设置在广播包内。然后第一移动终端获取预设的公共地址，从而向无线局域网发送接受地址为公共地址的广播包，以便于第二移动终端接收广播包。其中，公共地址的IP一般为255.255.255.255。当然，还可以是第一移动终端在提前获取第二移动终端的IP地址后直接将广播包通过无线局域网设备发送至第二移动终端上。In this step, since each mobile terminal will obtain a specific IP address after connecting to the wireless local area network, the first mobile terminal can set the IP address of the first terminal in the broadcast packet when generating the broadcast packet. Then, the first mobile terminal acquires a preset public address, so as to send a broadcast packet whose acceptance address is the public address to the wireless local area network, so that the second mobile terminal can receive the broadcast packet. Among them, the IP of the public address is generally 255.255.255.255. Of course, the first mobile terminal may also directly send the broadcast packet to the second mobile terminal through the wireless local area network device after acquiring the IP address of the second mobile terminal in advance.
在一较佳实施例中，第一移动终端接收由第二移动终端发送的应答包，并根据所接收的应答包与第二移动终端建立通信通道的步骤包括：In a preferred embodiment, the first mobile terminal receives the response packet sent by the second mobile terminal, and the steps of establishing a communication channel with the second mobile terminal according to the received response packet include:
第一移动终端识别应答包内的IP地址；The first mobile terminal identifies the IP address in the response packet;
根据应答包内的IP地址与第二移动终端建立通信通道。Establish a communication channel with the second mobile terminal according to the IP address in the response packet.
本步骤中，第一移动终端识别应答包内的信息为IP地址或拒接标识符中的哪一种，若为拒接标识符则代表建立通信通道失败，从而第一移动终端自动退出通信模式；若为IP地址，则与第二移动终端形成TCP长连接，以此在第一移动终端与第二移动终端之间建立通信通道，从而构成了进行通信的必要条件。In this step, the first mobile terminal identifies whether the information in the response packet is the IP address or the rejection identifier. If it is the rejection identifier, it means that the establishment of the communication channel fails, so that the first mobile terminal automatically exits the communication mode. If it is an IP address, a long TCP connection is formed with the second mobile terminal, thereby establishing a communication channel between the first mobile terminal and the second mobile terminal, thus constituting a necessary condition for communication.
在一较佳实施例中，在第一移动终端接收由第二移动终端发送的应答包，并根据所接收的应答包与第二移动终端建立通信通道的步骤之后还包括：In a preferred embodiment, after the first mobile terminal receives the response packet sent by the second mobile terminal and establishes a communication channel with the second mobile terminal according to the received response packet, the method further includes:
第一移动终端采集通讯信息；The first mobile terminal collects communication information;
将通讯信息转换成二进制数据串；Convert communication information into binary data strings;
将二进制数据串发送至通信通道内。Send a string of binary data into the communication channel.
本步骤中，第一移动终端采集的通讯信息可以是文字、图像以及声音中的一种或多种，具体采集的方式参照现有的方式进行即可。同时，为了方便通讯信息在通信通道内传输，还需将上述通讯信息转换成二进制数据串，然后将转化后的二进制数据串发送到通信通道内，具体转换的方式也可参照现有方式。In this step, the communication information collected by the first mobile terminal may be one or more of text, image and sound, and the specific collection method may refer to the existing method. At the same time, in order to facilitate the transmission of communication information in the communication channel, the above communication information needs to be converted into a binary data string, and then the converted binary data string is sent to the communication channel. The specific conversion method can also refer to the existing method.
在一较佳实施例中，在第一移动终端接收由第二移动终端发送的应答包，并根据所接收的应答包与第二移动终端建立通信通道的步骤之后还包括：In a preferred embodiment, after the first mobile terminal receives the response packet sent by the second mobile terminal and establishes a communication channel with the second mobile terminal according to the received response packet, the method further includes:
第一移动终端读取通信通道内的二进制数据串；The first mobile terminal reads the binary data string in the communication channel;
将读取的二进制数据串转换成可显示或播放的信息。Convert the read binary data string into information that can be displayed or played.
本步骤中，在第一移动终端读取到通信通道内的二进制数据串(非第一移动终端自身发送的二进制数据串)后进行转换，以得到第一移动终端可播放或显示的信息。其中，当第二移动终端为多个时，建立的通信通道可以为由第一移动终端分别与多个第二移动终端分别建立单独的通信通道，而其中任意一个第二移动终端可以是无法获取另外第二移动终端的发出的通讯信息，也可以是通过以第一移动终端为中转站获取其余第二移动终端发出的通讯信息，即第一移动终端在收到其中一个第二移动终端发送的通讯信息后还将该通讯信息发送至其余的第二移动终端，优选这两种状态可以通过第一移动终端的用户自由切换。In this step, after the first mobile terminal reads the binary data string in the communication channel (not the binary data string sent by the first mobile terminal itself), the conversion is performed to obtain information that can be played or displayed by the first mobile terminal. Wherein, when there are multiple second mobile terminals, the established communication channels may be separate communication channels established by the first mobile terminal and multiple second mobile terminals respectively, and any one of the second mobile terminals may be unavailable for acquisition. In addition, the communication information sent by the second mobile terminal can also be obtained by using the first mobile terminal as a transfer station to obtain the communication information sent by the other second mobile terminals, that is, the first mobile terminal receives the communication information sent by one of the second mobile terminals. After the communication information, the communication information is also sent to the remaining second mobile terminals. Preferably, the two states can be freely switched by the user of the first mobile terminal.
在一较佳实施例中，优选第二移动终端为具备通无线功能的机器人，如现有工厂内的协作机器人，从而便于管理用户与操作协作机器人的普通用户进行通信。In a preferred embodiment, preferably, the second mobile terminal is a robot with wireless communication function, such as a collaborative robot in an existing factory, so as to facilitate communication between management users and ordinary users who operate the collaborative robot.
在上述第一移动终端与第二终端构建通信通道的过程中，第二终端则按照如下方式进行：In the above-mentioned process of building a communication channel between the first mobile terminal and the second terminal, the second terminal performs as follows:
第二移动终端根据接收到的广播包开启TCP协议并向无线局域网设备发送应答包。The second mobile terminal starts the TCP protocol according to the received broadcast packet and sends a response packet to the wireless local area network device.
第二移动终端与接收到应答包的第一移动终端建立通信通道。The second mobile terminal establishes a communication channel with the first mobile terminal that has received the response packet.
本步骤中，第二移动终端接收广播包并进行识别后即可开启TCP协议，然后再向无线局域网发送应答包。其中，应答包包含的内容可以是第二移动终端的特定编号。其中，第二移动终端可在连接无线局域网后随时接收无线局域网内的所有广播包，当然，此时第二移动终端只是代称，并不只是一个移动终端，也可以是多个移动终端同时接接收广播包。最后，第二移动终端在第一移动终端接收到应答包后即可与第一移动终端形成TCP长连接，以此在第二移动终端与第一移动终端之间建立通信通道，从而构成了进行通信的必要条件。In this step, after receiving the broadcast packet and identifying it, the second mobile terminal can start the TCP protocol, and then send a response packet to the wireless local area network. The content contained in the response packet may be a specific number of the second mobile terminal. The second mobile terminal can receive all broadcast packets in the wireless local area network at any time after connecting to the wireless local area network. Of course, the second mobile terminal is just a proxy name at this time, not just a mobile terminal, but also a plurality of mobile terminals receiving and receiving at the same time. broadcast packets. Finally, after the first mobile terminal receives the response packet, the second mobile terminal can form a long TCP connection with the first mobile terminal, thereby establishing a communication channel between the second mobile terminal and the first mobile terminal, thereby forming a communication channel.

生成含有第二移动终端IP地址的应答包并开启TCP协议；Generate a response packet containing the IP address of the second mobile terminal and open the TCP protocol;
向广播包内的IP地址发送应答包。Send a reply packet to the IP address in the broadcast packet.
本步骤中，第二移动终端识别广播包内的IP地址后，第二移动终端随即生成含有其IP地址的应答包并同步开启TCP协议，最后第二移动终端向无线局域网设备发送接受地址为广播包内的IP地址的应答包。当然，第二移动终端在接收到广播包后，若用于不想接听，则可通过拒接操作向接受地址为广播包内的IP地址发送拒接包。其中，拒接包内含有预设表示拒接含义且第一移动终端可识别的标识符。In this step, after the second mobile terminal identifies the IP address in the broadcast packet, the second mobile terminal immediately generates a response packet containing its IP address and starts the TCP protocol synchronously, and finally the second mobile terminal sends the acceptance address to the wireless local area network device as broadcast The reply packet of the IP address in the packet. Of course, after receiving the broadcast packet, if the second mobile terminal does not want to answer the broadcast packet, it can send the rejection packet to the IP address whose accepting address is in the broadcast packet through a rejection operation. Wherein, the rejection packet contains a preset identifier indicating rejection and identifiable by the first mobile terminal.
在一较佳实施例中，在第二移动终端与接收到应答包的第一移动终端建立通信通道的步骤之后还包括：In a preferred embodiment, after the step of establishing a communication channel between the second mobile terminal and the first mobile terminal that has received the response packet, the method further includes:

In addition, the communication information sent by the first mobile terminal can also be obtained by using the second mobile terminal as a transfer station to obtain the communication information sent by the other first mobile terminals, that is, the second mobile terminal receives the communication information sent by one of the first mobile terminals. After the communication information, the communication information is also sent to the remaining first mobile terminals. Preferably, the two states can be freely switched by the user of the second mobile terminal.
