[0055] In the description, claims and the above drawings of the present invention, terms such as "first", "second", "third", "fourth", etc. (if any) are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances so that the embodiments described herein can be implemented in an order different from that illustrated or described herein. In addition, the term "comprising" or "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that comprises a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0056] For ease of understanding, the specific process of the embodiments of the present invention will be described below. Please refer to Figure 1 , a first aspect of the present invention provides a communication method for a radio group, including:

[0057] S100. Receive a group entry request from a radio device; in an optional embodiment of the present invention, the radio device may include an antenna, a PCBA circuit board, a display screen, a housing, a button, a power supply / battery; wherein the PCBA board includes a radio frequency module, a control module, a power module, an audio module, a display module, etc. The radio device can be configured as an administrator role and a general user role based on needs. In the present invention, the device that receives the group entry request from the radio device can be the device of the group administrator or the total management device of all radio devices, and the group entry information requested by the radio device is carried in the group entry request.

[0058] S200. Analyze the group entry request to obtain the group entry information of the radio device; in the present invention, the group entry information includes the device information of the radio device (including role information and hardware information) and the group information of the group to be joined. The present invention mainly generates the radio coding information (all groups and contacts) of the system and the communication frequency bands of each group through the management terminal, and then activates the local machine as a specific use coding information of the system and synchronizes the radio coding and communication frequency bands of the system contacts and groups through the management terminal. When communicating across groups, a common frequency band is used, otherwise the communication frequency band of the current group is used.

[0059] S300. Generate the communication code of the radio device based on the enrollment information. In the present invention, the role of the communication code is to identify the identity of the radio device. In each group, the communication codes of each radio device are different. In an optional implementation manner of step S300 of the present invention, generating the communication code of the radio device based on the enrollment information includes: obtaining the identity type of the radio device from the enrollment information; obtaining the identity code of the radio device based on the identity type; obtaining the target group of the radio device from the enrollment information; obtaining the group code of the radio device based on the target group; and combining the identity code and the group code to obtain the communication code of the radio device. Briefly speaking, the communication code of the radio device in the present invention is mainly composed of group code information (i.e., group code) and device code information (i.e., identity code), and there is a mapping relationship between the group code and the role, which can be set as follows. For example, for the four-digit code 0011, 00 is the group code and it is the administrator group, and 11 is the personal code of the administrator; for example, 0122, 01 is the user group code, and 22 is the personal code of the user. After the communication code of the device is generated, the communication code will be stored in the memory of the radio device.

[0060] S400. Obtain the communication frequency band information of the radio device, where the communication frequency band information includes a public communication frequency band and an intra-group communication frequency band. In the present invention, the public communication frequency band is mainly used for the radio device to perform cross-group or all-group communication, and the intra-group communication frequency band is mainly used for the radio device to perform intra-group communication. And in the present invention, different radio frequency bands are allocated to different groups, aiming to prevent the communication frequency band from being occupied, resulting in abnormal termination, retransmission, and delay of communication. The definition of the communication frequency point is on the radio device where the administrator is located, and the configuration is synchronized by the administrator to other radio devices. The identity verification is also configured by the administrator's radio device and then distributed and synchronized to other radio devices. The networking configuration information, such as the allocation of group frequency bands, group and personal communication codes, etc., is synchronized by the device where the administrator is located to the relevant devices through a radio / wired interface (such as a serial port). The relevant configuration information cannot be modified or the configuration permission cannot be modified by other devices. The device identity information / communication code is set by the device where the administrator is located through a radio / wired interface (such as a serial port). This information cannot be modified on the device.

[0061] S500. When the radio device conducts in-group communication, it transmits and receives information based on the communication code and through the in-group communication frequency band. As mentioned in step S400 above, the radio device of the present invention mainly uses the in-group communication frequency band for in-group communication. For example, the communication among administrators in the administrator group can be set to frequency point F1, and the internal communication within the user group can be set to frequency group F2. The radio device uses its communication code as the identity identifier of the device to conduct communication within the group.

[0062] In an optional implementation manner of step S500 of the present invention, the step of when the radio device conducts in-group communication and transmits and receives information based on the communication code and through the in-group communication frequency band includes:

[0063] S501. Occupy the in-group communication frequency band in advance through an empty carrier signal. In the present invention, for information communication, there is a section of empty carrier in the initial stage of the carrier to occupy the frequency, improve communication reliability, and the length of the empty carrier wave is automatically adjusted according to the quality of the communication network, with low latency so as not to affect the user experience. The empty carrier outputs an empty analog signal for broadcasting at the corresponding frequency point to occupy this frequency point and notify other radio devices in the standby state of the following information: there is already a device transmitting, it is necessary to disable transmission and receive the analog signal in the carrier wave, and wait for the analog signal and digital information to be encoded and decoded.

[0064] S502. Package and encapsulate the information to be sent based on the in-group communication protocol to obtain a digital communication signaling set. In an optional implementation manner of the first aspect of the present invention, the step of packaging and encapsulating the information to be sent based on the in-group communication protocol to obtain a digital communication signaling set includes: obtaining the protocol layer information of the in-group communication protocol; obtaining the information frame format based on the protocol layer information, and the information frame format includes source code, destination code, communication number, service protocol type, information packet index, number of information packets, information packet length, information packet content, and frame check code; obtaining the size of the information to be sent, and obtaining the number of sub-packets of the information to be sent based on the size; sub-packaging the information to be sent based on the number of sub-packets and encapsulating it based on the information frame format to obtain a digital communication signaling set. In the present invention, the source and destination codes in the information frame can be used for point-to-point, point-to-group, and point-to-whole-network scenario communication information frames at the service layer. The packet index and number of packets can be used for sub-packaging processing when transmitting a large amount of information data. The content can be set with data content at the service layer, and can include various forms of digital information such as digital voice information, text information, and picture information, and also includes the response code for the information packet.

[0065] S503. Sequentially send the digital communication signaling set to the target devices within the group; in the present invention, the digital communication signaling set can be sequentially sent to the target devices within the group according to the order of the packet index, and then the target devices restore the messages according to the packet index. When the carrier is sent in the present invention, redundant propagation is performed on the information content. The redundancy mechanism of the present invention will carry the number of the information digits in the frame header of the carrier protocol, and the protocol layer can perform duplicate removal processing according to the information number; due to the relevant characteristics of analog signals, frames are easily lost in the carrier (the impact is not obvious in analog voice communication, and the voice can still be normally played even if frames are lost), so "incomplete information" is more likely to occur during the transmission of digital information, and the transmitting device needs to retransmit. Under the redundancy mechanism, the information packets to be transmitted are transmitted multiple times in the carrier (single communication), and the protocol layer reorganizes the transmitted information in order to obtain a complete information packet in a single communication, reduce the retransmission rate, and have a low information packet delay rate (retransmission requires waiting for a response and retransmission again, two communications). In order to better perform signaling communication, the digital communication signaling of the present invention can perform FSK modulation and demodulation on the analog signal 1200 - 2400.

[0066] S504. Receive the response information returned by the target device; in the present invention, after each digital communication signaling in the digital communication signaling set is sent to the target device or when the target device does not receive subsequent digital communication signaling within a certain time interval, the target device will return a response information, which will record whether the digital communication signaling is successfully received, and which digital communication signaling sets the target device has received currently, etc., so that after the radio device receives the response information, corresponding measures can be enabled for processing, such as instruction retransmission.

[0067] S505. Adjust the occupancy duration of the empty carrier signal based on the response information, and retransmit the missing sub-packets of the digital communication signaling. In the present invention, the occupancy duration of the empty carrier signal can be automatically adjusted. That is, during the communication process, when it is found that the signal with "retransmission required" appears multiple times in the response, it indicates that the current network signal quality is poor, and the occupancy duration of the empty carrier frequency is automatically adjusted to be slightly longer. For example, at the initial communication, the empty carrier duration is 100 ms. Subsequently, when more than 3 "retransmission required" signaling are received, within a certain period of time, the occupancy duration of the empty carrier is 200 ms. When the network returns to normal and the "retransmission required" signaling is reduced to 2 times or less, the occupancy duration of the empty carrier is reduced to 150 ms and 100 ms in sequence. That is, in an optional implementation manner of this step of the present invention, the adjusting the occupancy duration of the empty carrier signal based on the response information includes: counting the number of retransmissions in the response information; determining whether the number is greater than a preset threshold; if the number is less than or equal to the preset threshold, the occupancy duration of the next empty carrier signal maintains the default value; if the number is greater than the preset threshold, the occupancy duration of the next empty carrier signal is increased to a preset value.

[0068] In an optional implementation manner of the first aspect of the present invention, the retransmitting the missing sub-packets of the digital communication signaling includes: obtaining the index of the missing information packet from the response information; determining the digital communication signaling to be retransmitted based on the information packet index; and retransmitting the digital communication signaling. In the present invention, the response information can be the entire response information returned once after all the digital communication signaling are sent, or the response information is returned once for each digital communication signaling received by the target device, or the response information is returned once when no next digital communication signaling is received within a preset time interval after receiving a digital communication signaling. The technical solution of the present invention will retransmit the failed digital communication signaling after the digital communication signaling fails to improve the reliability of the digital communication signaling transmission.

[0069] In an optional implementation manner of the first aspect of the present invention, after retransmitting the digital communication signaling, it includes: parsing the digital communication signaling set in the target device to obtain the information packet index and information packet content of each digital communication signaling; and sequentially reorganizing the information to be sent in the target device based on the information packet index and the information packet content of each digital communication signaling. In the present invention, when the information to be sent is sub-packaged, corresponding information packet indexes will be generated. The information packet index records the information and order of each information packet. Each time the target device receives a digital communication signaling, it can parse the carried information packet index and information packet for subsequent restoration.

[0070] S600. When the radio device conducts public communication, it transmits and receives information based on the communication code through the public communication frequency band. In the present invention, when the radio device conducts public communication, it also has the means of "idle carrier frequency occupation", "digital signaling transmission", and "digital signaling redundancy" used in step S500 of the present invention. The steps of public communication of the radio device in the present invention are similar to those of intra-group communication, and the only difference lies in the different communication frequency bands used. Therefore, the present invention will not elaborate on this here.

[0071] The main features of the communication method of the radio group in the present invention are the mapping mechanism of communication frequency points and group communication, the setting of communication codes, the setting of communication carrier frequency occupation, and the setting of redundancy mechanisms. The communication method of the radio group in the present invention greatly reduces costs compared to radio digital communication systems, innovatively designs in terms of communication reliability and availability, and improves the availability and reliability of radio analog communication. While bringing a convenient experience to the majority of users, the present invention can also bring economic value with lower costs.
