Example one

Fig. 1 is a flow chart of the intercom communication method provided in the first embodiment of the present invention. This embodiment is applicable to the communication data transmission between interphones. The method can be executed by the intercom communication device and includes the following steps:

S110. The first walkie-talkie sends a communication request on a common channel to control at least one second walkie-talkie to jump to a preset channel, the communication request includes at least a target address and communication parameters, and the target address is preset to at least one second walkie-talkie The identification code of, the communication parameter includes a preset channel;

It should be noted that the common channel refers to a channel including all walkie-talkies, and all walkie-talkies will be in the common channel.

A communication request refers to a request sent when it needs to communicate with other walkie-talkies. The communication request includes at least the target address and communication parameters. "At least" means that the target address and communication parameters are necessary, but the communication request can also include other content. For example, the sending address, sending time, etc., can be increased as needed to realize the richness of the content contained in the communication request.

The target address refers to the address that can locate the target walkie-talkie. The target walkie-talkie is the walkie-talkie that needs to communicate. Exemplarily, the target address can be provided by the application layer. Optionally, the calculation formula of the target address can be a 7-digit number generated from the identification code of the user associated or using the walkie-talkie, such as 1234567, and then converted into hexadecimal 0x12D687 Generate 3 bytes of data.

The communication parameters include a preset channel. The preset channel refers to a communication channel established between walkie-talkies to communicate with the target walkie-talkie only. Exemplarily, if walkie-talkie A wants to communicate with walkie-talkie B, walkie-talkie A and walkie-talkie B enter the preset channel, A and B can communicate in the preset channel, and walkie-talkies that are not in the preset channel cannot see A The communication content of the walkie-talkie and the B walkie-talkie. The number of channels can be multiple to satisfy communication between different walkie-talkies. The channel in this embodiment can include 302 channels.

In one embodiment, each walkie-talkie pre-stores an identification code corresponding to a user name or user identity, and the identification code of each walkie-talkie is inconsistent. Therefore, through the identification code, it is possible to determine which walkie-talkie the walkie-talkie is. The target address is preset to the identification code of at least one second walkie-talkie, which means that the target address can be set to one identification code or multiple identification codes. When the target address is set to an identification code, the walkie-talkie that controls the identification code jumps to the preset channel, then there are only two walkie-talkies in the preset channel. When the target address is set to multiple identification codes, the multiple walkie-talkies corresponding to the multiple identification codes are controlled to enter the preset channel, and multiple walkie-talkies in the preset channel can communicate with multiple parties. For example, the multiple walkie-talkies in this embodiment can One-to-many sending messages for full chat interaction. The communication request sent by the first walkie-talkie in the public channel in this embodiment may be generated based on the buddy list or group name pre-stored by the first walkie-talkie, and the buddy names in the buddy list are preset to be used by friends during the process of adding friends. The identification code of the walkie-talkie.

In an alternative embodiment, the identification code on the walkie-talkie may be determined by the user, regardless of the identification of the walkie-talkie, and the identification code is determined according to the user's identity. The identification code corresponding to each user may be fixed or not. Optionally, the identification code corresponding to each user is fixed. Exemplarily, the identification code corresponding to user A is 1234, and the identification code corresponding to user B is 4321. When user A uses intercom C, the corresponding identification code of intercom C is set to 1234, and when user B uses intercom D, the corresponding identification code of D intercom is The identification code is set to 4321. If user A uses walkie-talkie D, the identification code of walkie-talkie D will be set to 1234. Optionally, if no user uses the walkie-talkie, the walkie-talkie has no identification code. Optionally, set a memory chip in the walkie-talkie. When the user uses the walkie-talkie, the user name or user ID in the mobile phone will be sent to the walkie-talkie after connecting to the walkie-talkie through the mobile phone’s Bluetooth. The walkie-talkie pre-stores the user name or user ID as the walkie-talkie’s Identification code to determine the identification code corresponding to the walkie-talkie. When the user is not using the walkie-talkie, disconnect the Bluetooth connection between the mobile phone and the walkie-talkie. At this time, the walkie-talkie will store the user name or user ID stored in the chip as the identification code of the walkie-talkie Delete, the walkie-talkie enters the standby state. Other methods that can realize the identification of the user by the walkie-talkie can be substituted. In this alternative embodiment, the identification code on the walkie-talkie is determined according to the user ID of the user, ensuring that when the user uses different walkie-talkies or the same walkie-talkie is used by different users, the communication data can be received by the user corresponding to the user ID. More convenient.

S120: The first walkie-talkie jumps to the preset channel after sending the communication request;

After controlling at least one second walkie-talkie to jump to the preset channel, the first walkie-talkie will also jump to the preset channel. Only the walkie-talkies in the same preset channel can communicate.

S130: The first walkie-talkie sends communication data to at least one second walkie-talkie on the preset channel based on the target address.

It should be noted that the communication data refers to the data sent by the first walkie-talkie to the second walkie-talkie. Exemplarily, the communication data may include text, pictures, voice, video, files, etc., and different communication data may be sent according to different needs. If the target address is set as an identification code, the first walkie-talkie can send communication data to the walkie-talkie corresponding to an identification code in the preset channel according to the target address. If the target address is set to multiple identification codes, the first walkie-talkie can send communication data to multiple walkie-talkies corresponding to the multiple identification codes in the preset channel according to the target address.

In the technical solution of the embodiment of the present invention, after a communication request is sent through the walkie-talkie, a preset channel is established between the walkie-talkies, and only the walkie-talkie whose target address is set to the identification code can enter the preset channel, and only in the same preset channel Only the intercom inside can see the communication data, which solves the insecurity of intercom communication and realizes the effect of improving the confidentiality of the intercom communication. In an embodiment, since the communication request prepared before sending the message in this embodiment can be directly generated by selecting the sender from the friend list, the target selection of the intercom communication is convenient and the communication method is simple.

Example two

Fig. 2 is a flowchart of an intercom communication method according to the second embodiment of the present invention. This embodiment is a further refinement of the above technical solution, and is suitable for the scenario of communication data transmission between walkie-talkies. The method can be executed by an intercom communication device and includes:

S210. The first walkie-talkie sends a communication request on the common channel to control at least one second walkie-talkie to jump to a preset channel, the communication request includes at least a target address and communication parameters, and the target address is preset to at least one second walkie-talkie The identification code of, the communication parameter includes a preset channel;

S220: The first walkie-talkie jumps to the preset channel after sending the communication request.

S230: The first walkie-talkie judges whether the response information sent by the at least one second walkie-talkie from the preset channel is received;

It should be noted that the response message refers to the response of the walkie-talkie confirming to enter the preset channel. For example, it can be words such as "XX walkie-talkie has joined the preset channel". XX represents a two-way radio, which can be set according to requirements. If the first walkie-talkie receives the response message, it means that the second walkie-talkie has entered the preset channel and can send communication data to the second walkie-talkie. Similarly, if the target address is set to an identification code, at most only one walkie-talkie can send a response message. If the walkie-talkie does not enter the preset channel, there is no response message. If the target address is set to multiple identification codes, for example, 10 identification codes, only the walkie-talkie corresponding to 10 identification codes can send 10 response messages at most, and the step of sending response messages can also be omitted in the alternative embodiment.

S240. The first walkie-talkie sends communication data to at least one second walkie-talkie on the preset channel based on the target address.

As shown in FIG. 3, in an alternative embodiment, step S210 can be replaced by:

S211: The first walkie-talkie sends a communication request to the third walkie-talkie on the common channel to control the third walkie-talkie to control at least one second walkie-talkie to jump to a preset channel;

It should be noted that when the distance between the first walkie-talkie and the second walkie-talkie is too far to establish communication normally, the third walkie-talkie can be used to establish normal communication. Exemplarily, the first walkie-talkie searches for a third walkie-talkie within a preset range (the preset range can be 1 km or 2 km, and the acceptable range is determined according to the hardware of the walkie-talkie), the third walkie-talkie and the first walkie-talkie The distance to the second walkie-talkie is within the preset range. Through the third walkie-talkie, bridge the first walkie-talkie to the second walkie-talkie. The first walkie-talkie first sends the communication request or communication data to the third walkie-talkie, and the third walkie-talkie sends the communication request or communication data to the second walkie-talkie, thereby increasing the communication distance between the first walkie-talkie and the second walkie-talkie. Optionally, a fourth walkie-talkie and a fifth walkie-talkie can also be added to make the communication range wider. Optionally, when the third walkie-talkie is in a working state, the communication request or communication data sent by the first walkie-talkie will be cached on the first walkie-talkie, and the working state of the third walkie-talkie will be continuously monitored. When the third walkie-talkie is in a non-working state, the first walkie-talkie sends the buffered communication request or communication data to the third walkie-talkie, thereby controlling the third walkie-talkie to send the communication request and communication data to the second walkie-talkie.

Correspondingly, when step S210 is replaced with step S211, step S240 can be replaced with:

S241. The first walkie-talkie sends communication data to a third walkie-talkie on the preset channel to control the third walkie-talkie to send communication data to at least one second walkie-talkie on the preset channel based on the target address.

It should be noted that the preset channels of the first walkie-talkie and the third walkie-talkie, and the preset channels of the third walkie-talkie and the second walkie-talkie are one preset channel. When it is a preset channel, the first walkie-talkie and the second walkie-talkie can communicate in a preset channel through the third walkie-talkie. Optionally, it can also be different preset channels. For different preset channels, for example, a preset channel can be established between the first walkie-talkie and the third walkie-talkie, and after the communication data is transmitted to the third walkie-talkie, the walkie-talkie will establish another preset channel with the second walkie-talkie , So as to transmit the communication data to the second walkie-talkie on another preset channel. Optionally, selecting a preset channel can reduce resource waste in the communication process.

As shown in FIG. 4, in another alternative embodiment, step S240 can also be replaced by:

S242. After the first walkie-talkie determines that the response information sent by the at least one second walkie-talkie from the preset channel is received, the first walkie-talkie sends communication data to the at least one second walkie-talkie on the preset channel based on the target address. Otherwise, the first walkie-talkie cancels sending communication data to at least one second walkie-talkie based on the target address on the preset channel.

It should be noted that only when the first walkie-talkie receives the response message, the second walkie-talkie has entered the preset channel, and the communication data sent by the first walkie-talkie can be received by the second walkie-talkie. If the response message is not received, it means that the second walkie-talkie has not entered the preset channel. At this time, the communication data sent by the first walkie-talkie cannot be received by the second walkie-talkie, so cancel the communication data transmission, otherwise it will occupy the resources of the preset channel .

As shown in FIG. 5, in another alternative embodiment, step S230 can also be replaced with:

S231. The communication request further includes confidential information, and the communication data is encrypted based on an encryption method defined by the confidential information.

It should be noted that confidential information can be a rule or method for encrypting communication data. Encrypting communication data can improve the security of communication data. Correspondingly, in step S240, the encrypted information must be decrypted before it can be acquired by the second walkie-talkie.

As shown in FIG. 6, optionally, after step S240, it may further include:

S250: The first walkie-talkie judges whether to receive data reception confirmation information sent by at least one second walkie-talkie from a preset channel;

It should be noted that the confirmation message refers to the confirmation that the second walkie-talkie receives the signal of the communication data sent by the first walkie-talkie. If the first walkie-talkie can receive the confirmation message, it means that the second walkie-talkie has received the communication data sent by the first walkie-talkie, and step S260 is executed to prompt that the data transmission is normal. Exemplarily, the prompt that the data is sent normally may be "the other party has received the communication data", which is not displayed here.

If the first walkie-talkie cannot receive the confirmation message, it means that the second walkie-talkie has not received the communication data, and S270 is executed to prompt the data transmission failure. Exemplarily, the prompt of data transmission failure may be "the other party did not receive communication data".

Optionally, the communication data or communication request further includes one or more of the data header, the sending address, the data type, the data length, the encryption information, and the checksum data.

In one embodiment, the data header is a fixed value, such as 0x5a in hexadecimal notation. The sending address is the address of the first intercom, and the identification code (Identity, ID) of the first intercom can be used. The ID calculation formula of the first walkie-talkie can be a 7-digit number generated from the user identification code or user name, such as 1234567, and then converted to hexadecimal 0x12D687 to generate 3 bytes of data. Data types may include communication guidance, text data, voice data, SOS data, communication data, and so on. You can perform different operations for different data according to different data types. Exemplarily, low-speed transmission is used for text data, and high-speed transmission is used for voice data, which can be set as required. The data length can include two aspects, the data protocol part and the user data part. The encrypted information is used as a secondary AES128 encryption. When sending communication data, first verify the validity of the communication data. Data refers to user data, optional, the data does not exceed 120 bytes, which has reduced the pressure of the communication process.

In the technical solution of the embodiment of the present invention, by adding the judgment of whether the first walkie-talkie receives the response information before sending the communication data, it will enter the preset channel after the second walkie-talkie confirms, preventing the user from maliciously sending a communication request to make the second walkie-talkie enter The dangerous communication data is sent after the channel is preset, which improves the safety of the communication process.

Example three

Fig. 7 is a flow chart of an intercom communication method provided in the third embodiment of the present invention. This embodiment is further modified on the basis of the above-mentioned embodiment, and is suitable for a scenario before sending a request. As shown in Figure 7, the method can be executed by an intercom communication device, including:

S310. The first walkie-talkie selects the friend name or group name to be called from the friend list;

In a specific implementation, the verified friends or groups will be displayed in the friends list. When you need to communicate, select the name of your friend or group in the friend list, and then you can communicate after entering the same preset channel.

S320. Obtain one or more preset identification codes of the second walkie-talkie corresponding to the friend name or group name;

In this embodiment, the identification code of one or more second walkie-talkies is acquired as the target address, and the identification code of the second walkie-talkie in this embodiment is preset by the selected friend name or group name.

It should be noted that the friend name and group name are used to facilitate target search when communication is required. However, when communicating, the identification code of the walkie-talkie is still needed to establish the same preset channel for communication data transmission. By pre-associating the friend's name or group name with the identification code of the walkie-talkie, it is convenient to search during communication. In this embodiment, the name of the friend in the friend list is pre-associated with the identification code of the walkie-talkie used by the friend during the process of adding the friend.

S330. Select a preset channel according to the identification code of the one or more second walkie-talkies;

It should be noted that before the communication data transmission, the walkie-talkie needs to be in the same preset channel. Therefore, only by selecting a preset channel according to the identification code of the two-way radio can the communication between the two-way radios be realized. In this embodiment, if there are few communication objects (only communicating with one second walkie-talkie), the low-speed channel can be selected as the preset channel. If there are many communication objects (communication with multiple second walkie-talkies), the high-speed channel can be selected as Preset channels.

S340: Generate the communication request according to the identification code of the one or more second walkie-talkies and the preset channel;

S350. The first walkie-talkie sends a communication request on a common channel to control at least one second walkie-talkie to jump to a preset channel, the communication request includes at least a target address and communication parameters, and the target address is preset to at least one second walkie-talkie The identification code of, the communication parameter includes a preset channel;

S360. The first walkie-talkie jumps to the preset channel after sending the communication request.

S370. The first walkie-talkie sends communication data to at least one second walkie-talkie on the preset channel based on the target address.

As shown in FIG. 8, optionally, after step S330, it may further include:

S331. The first walkie-talkie jumps to the selected preset channel for occupation detection;

It should be noted that due to the large number of people using walkie-talkies and the limited number of channels, the preset channel requested for communication may not be usable. When the preset channel is occupied, other walkie-talkies cannot use the preset channel. Therefore, after the first walkie-talkie selects the preset channel, in order to prevent unavailability, it jumps to the preset channel in advance to perform occupation detection. Exemplarily, when preset channel 1 is occupied, other walkie-talkies can no longer enter preset channel 1, and can only enter after preset channel 1 is used. If the first intercom can jump to the preset channel, it means that the preset channel is not occupied and can be used. Otherwise it cannot be used.

S332: If the selected preset channel is occupied, the first intercom selects another preset channel;

It should be noted that if the preset channel is occupied, it cannot be used, so another preset channel needs to be selected. The other preset channel can only be used when it is not occupied. In an alternative embodiment, the selection of the preset channel can be automatically determined by a random algorithm.

In an alternative embodiment, step S331 and step S332 can also be replaced with:

The communication parameter also includes a communication speed. The communication speed is set according to different types of communication data. The type of communication data includes one or more of communication guide data, text data, voice data, and SOS data.

It should be noted that the communication speed refers to the speed of sending communication data. Different communication data types have different requirements for communication speed. Text data may require a lower communication speed because of the short data length. Voice data may require a higher communication speed. The communication speed can be set as required.

As shown in FIG. 9, optionally, before step S310, it may further include:

S301. Receive the friend name or group name input from the first walkie-talkie;

It should be noted that the friend name is associated with the identification code of the walkie-talkie. The walkie-talkie with the identification code associated with the friend's name can be found through the friend's name. In this embodiment, the friend identification code corresponding to the friend name is preset as the identification code of the walkie-talkie.

In an embodiment, the group name may correspond to multiple friend names.

S302: The first walkie-talkie generates a friend addition request according to the friend name or group name, and sends the friend addition request on a public channel;

S303: The first walkie-talkie receives the friend confirmation information sent by the second walkie-talkie on the public channel to complete the friend addition action, where the friend confirmation information includes the identification code of the second walkie-talkie.

The technical solution of the embodiment of the present invention adds a step of adding a friend name or group name before sending a communication request, so that only friends or group names in the friend list can establish a preset channel, and not a friend or group name in the list. Establish the same preset channel to complete fast communication, which greatly facilitates the use of intercom communication.

Example four

FIG. 10 is a flowchart of an intercom communication method provided by Embodiment 4 of the present invention. This embodiment is a further refinement of the above-mentioned technical solution, and is suitable for a scenario where a walkie-talkie receives communication data. The method can be executed by an intercom communication device and includes:

S410.
