Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a communication device with multiple frequencies online simultaneously and having multiple group call communication functions. Background Art

[0002] Communication is a process of information transmission and exchange, which aims to transfer information from one entity (human or machine) to another entity to achieve information sharing and understanding. The basic elements of communication include information source, information, channel and receiver. Among them, the information source is the entity that generates information, which can be an individual, organization or machine; information is the core content of communication, which can be in various forms such as text, image, sound, video, etc.; the channel is the medium for information transmission, which can be physical media such as wires, optical fibers, radio waves, or digital media such as social media and e-mail; the receiver is the recipient of the information and is responsible for decoding and understanding the transmitted information. In the prior art, walkie-talkie communication technology, as an important branch of communication technology, is a technology used to achieve short-range wireless communication, which is widely used in public safety, military, emergency rescue, commerce, transportation, medical care, education and other fields.

[0003] For example, the invention patent with application number 201710788469.X discloses a communication method of a walkie-talkie system, wherein the walkie-talkie system includes a master unit and at least one slave unit, and is characterized in that the master unit can switch between normal communication mode and pairing communication mode, and at least one of the slave units can only work in the pairing communication mode. However, the application requires the master unit to monitor and switch frequencies, and when the master unit detects that the frequency of the slave unit has changed, it re-pairs by changing the frequency. This is a time-sharing switching frequency.

[0004] For another example, the patent document with publication number CN118660274 A discloses a communication management method and system for a walkie-talkie group. The invention relates to the technical field of walkie-talkie communication management. The communication management method for the walkie-talkie group includes the following steps: Step (a), grouping: users can establish fixed groups or dynamic groups in the walkie-talkie system as needed. The communication management method and system for the walkie-talkie group can trigger an emergency alarm system when the walkie-talkie encounters an emergency, the vibration frequency of the walkie-talkie suddenly increases, or it is hit violently. The emergency alarm system sends an alarm signal to the walkie-talkie group user and automatically turns on the GPS positioning system of the alarming user, which is convenient for determining the location of the emergency alarm and can quickly locate the specific user; improve the privacy of the walkie-talkie user. Except for the emergency alarm function caused by the occurrence of an emergency, if the walkie-talkie user turns off the GPS positioning system, the group user cannot view the location information of the setting user. This patent belongs to a transit management system.

[0005] However, in the prior art, the walkie-talkie communication technology similar to the above-mentioned patent is often used in a group of a certain size, and different groups have different work natures. If each group sets a different frequency point, each group can talk freely within it, but cannot communicate with members of other groups; if the entire group shares a frequency point, irrelevant noise will cause great interference to the work, work efficiency will be reduced, and confidentiality cannot be maintained.

[0006] Therefore, it is urgent to improve this shortcoming. The present invention studies and improves the existing technology and its shortcomings, and provides a communication device with multi-frequency simultaneous online and multiple group call communication functions. Summary of the invention

[0007] The object of the present invention is to provide a communication device with multi-frequency simultaneous online and multiple group call communication functions to solve the problems raised in the above background technology.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a communication device with multiple frequencies online at the same time and multiple group call communication functions, the communication device has and has at least one frequency point, and the frequency point is used as the basis for dividing the communication device groups, each frequency point is an independent communication channel, and only communication devices on the same channel can communicate with each other, and it supports multiple frequency points to be online at the same time, and the group division rule of the communication device is: communication devices with the same frequency point are divided into one group, and the same communication device can belong to multiple groups.

[0009] Furthermore, the communication device has a scanning function, which allows the device to quickly switch between the set frequency points to find an available communication channel. Specifically, when the device scans a signal on a certain frequency point, it will automatically stop scanning and lock on to the frequency point for communication.

[0010] Furthermore, the scanning process of the communication device includes the following steps:

[0011] S1. Setting frequency points: Users set the frequency points to be scanned on the communication device according to actual needs. These frequency points can be preset common channels or user-defined channels;

[0012] S2. Start scanning: The user starts the scanning function through the button or menu on the communication device, so that the communication device switches between the set frequency points in a preset order or a random order;

[0013] S3, receiving signal: when the device scans a frequency point and finds a signal, it will automatically stop scanning and lock on the frequency point. At this time, the user can hear the communication content from the frequency point;

[0014] S4. Talk: Once the communication device is locked on a certain frequency point, the user can start the call, and during the call, the device will remain on that frequency point until the call ends or the user manually switches to another channel.

[0015] Furthermore, the communication equipment frequency point setting method includes factory setting and customer free setting, and when setting the frequency point, it must be ensured that the selected frequency band complies with local radio management regulations to avoid using illegal frequency bands;

[0016] Factory settings: The communication equipment is preset with one or more frequency points when it leaves the factory, and the preset frequency points are set based on common communication needs and frequency band regulations, which can meet the basic communication needs of most users. When using the communication equipment, the user does not need to perform complex frequency settings, but only needs to select the appropriate channel according to actual needs. This setting method simplifies the operation process and makes the walkie-talkie easier to use;

[0017] The customer freely sets the frequency point, and provides two modes: manual frequency adjustment and programmed frequency adjustment. This setting mode is suitable for users who need flexible communication needs.

[0018] Furthermore, the manual frequency modulation is used to quickly switch the communication equipment to a specific frequency for communication. The specific operation is: the user manually selects or adjusts the frequency point through the buttons or knobs on the walkie-talkie, and provides a digital input function, allowing the user to directly input the required frequency value.

[0019] Furthermore, the programmed frequency modulation is aimed at users who need to set frequency points more accurately and flexibly. The specific operation is as follows: the user uses special programming software and a walkie-talkie connection cable to connect the walkie-talkie to the computer, and then enters the required frequency value and other communication parameters in the software. After the setting is completed, these parameters will be written into the walkie-talkie to achieve accurate frequency point setting.

[0020] Furthermore, the communication device needs to select the same frequency point as the receiver when sending voice. Only when both parties are at the same frequency point can the sent voice signal be correctly received and decoded by the receiver. Processing of other frequency points: If the device is not currently at the frequency point of the relevant group, but at other frequency points, then the sent voice signal will not be received by other users at the frequency point.

[0021] Furthermore, the communication device uses encryption technology or communication protocol during call communication to ensure that the communication content is not eavesdropped or tampered with during transmission.

[0022] Furthermore, the encryption technology specifically includes:

[0023] Analog encryption: Information is encrypted using analog signal processing techniques, including frequency domain scrambling (such as frequency inversion, band shift inversion, and frequency band splitting). In analog encryption, the original voice information is first converted into analog signals, and then these analog signals are processed using encryption algorithms to change their characteristics, making it difficult for unauthorized receivers to extract the original information from them.

[0024] Digital encryption: Digitizing voice signals and then encrypting them can provide higher confidentiality and reliability. In digital encryption, voice coding technology and data encryption technology are used to encrypt the user's initial plain speech, and then the secret speech is handed over to the intercom for conventional processing before transmission.

[0025] Furthermore, the communication protocol is specifically the HTTPS protocol, which is based on the HTTP protocol of SSL. It uses the HTTP protocol and adds an encryption and identity authentication layer between HTTP and TCP. During the HTTPS communication process, the client and the server will perform an SSL handshake, negotiate the security level, and establish a session key to ensure the secure transmission of the communication content.

[0026] The present invention provides a communication device with multiple frequencies online at the same time and multiple group call communication functions, which has the following beneficial effects:

[0027] The present invention uses multiple frequency points to be online at the same time, each frequency point can be factory set or freely set by the customer, and devices with the same frequency point are automatically divided into a group, and the communication devices within the same group can communicate and talk freely, but cannot communicate and talk with the communication devices of other groups. This group division method allows the devices in the same group to communicate and talk without obstacles without going through a transfer or management system, which makes the communication process simpler and more efficient, reduces the communication cost, and can prevent noise interference from irrelevant communications, truly realizing free communication and calls between terminals. On this basis, the present invention further uses encryption technology or communication protocols to keep the call communication process confidential to ensure that the communication content is not eavesdropped or tampered with during the transmission process. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 1 The present invention is a prior art schematic diagram of a communication device with multiple frequencies online simultaneously and having multiple group call communication functions. DETAILED DESCRIPTION

[0029] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0030] like Figure 1, a communication device with multiple frequencies online at the same time and multiple group call communication functions, the communication device has and has at least one frequency point, and the frequency point is used as the basis for dividing the communication device group, each frequency point is an independent communication channel, only the communication devices on the same channel can communicate with each other, and supports multiple frequency points to be online at the same time, the group division rule of the communication device: the communication devices with the same frequency point are divided into one group, and the same communication device can belong to multiple groups; at the same time, the communication device has a scanning function, which allows the device to quickly switch between the set frequency points to find an available communication channel, specifically, when the device scans a signal at a certain frequency point, it will automatically stop scanning and lock on the frequency point for talking; the scanning process of the communication device includes the following steps:

[0031] S1. Setting frequency points: Users set the frequency points to be scanned on the communication equipment according to actual needs;

[0032] S2. Start scanning: The user starts the scanning function through the button or menu on the communication device, so that the communication device switches between the set frequency points in a preset order or a random order;

[0033] S3, receiving signal: when the device scans a frequency point and finds a signal, it will automatically stop scanning and lock on the frequency point. At this time, the user can hear the communication content from the frequency point;

[0034] S4. Talk: Once the communication device is locked on a certain frequency point, the user can start the call, and during the call, the device will remain on that frequency point until the call ends or the user manually switches to another channel.

[0035] In this embodiment, the communication equipment frequency point setting methods include factory setting and customer free setting, and when setting the frequency point, it is necessary to ensure that the selected frequency band complies with local radio management regulations to avoid using illegal frequency bands;

[0036] Factory settings: The communication equipment is preset with one or more frequency points when it leaves the factory. The preset frequency points are set based on common communication needs and frequency band regulations, which can meet the basic communication needs of most users. When using the communication equipment, users do not need to perform complex frequency settings, but only need to select the appropriate channel according to actual needs. This setting method simplifies the operation process and makes the walkie-talkie easier to use;

[0037] Customers can freely set the frequency point: Users can freely set the frequency point, and two methods are provided: manual frequency adjustment or programmed frequency adjustment. This setting method is suitable for users who need flexible communication needs. Manual frequency adjustment is used to quickly switch the communication equipment to a specific frequency for communication. The specific operation is: the user manually selects or adjusts the frequency point through the buttons or knobs on the intercom, and provides a digital input function, allowing the user to directly enter the required frequency value. Programmed frequency adjustment is for users who need to set the frequency point more accurately and flexibly. The specific operation is: the user uses a dedicated programming software and an intercom cable to connect the intercom to the computer, and then enters the required frequency value and other communication parameters in the software. After the setting is completed, these parameters will be written into the intercom to achieve accurate frequency point setting.

[0038] In this embodiment, the communication device needs to select the same frequency point as the receiver when sending voice. Only when both parties are at the same frequency point can the sent voice signal be correctly received and decoded by the receiver. Processing of other frequency points: If the device is not currently at the frequency point of the relevant group, but at other frequency points, then the sent voice signal will not be received by other users at the frequency point. In addition, during the call communication process, the communication device uses encryption technology or communication protocol to ensure that the communication content is not eavesdropped or tampered with during the transmission process. Encryption technology specifically includes:

[0039] Analog encryption: Information is encrypted using analog signal processing techniques, including frequency domain scrambling (such as frequency inversion, band shift inversion, and frequency band splitting). In analog encryption, the original voice information is first converted into analog signals, and then these analog signals are processed using encryption algorithms to change their characteristics, making it difficult for unauthorized receivers to extract the original information from them.

[0040] Digital encryption: Digitizing voice signals and then encrypting them can provide higher confidentiality and reliability. In digital encryption, voice coding technology and data encryption technology are used to encrypt the user's initial plain speech, and then the secret speech is handed over to the intercom for routine processing before transmission. In this way, whether it is malicious interception or intentional or unintentional "third-party co-frequency / cross-frequency", what they hear is the invalid "noise" after modulation, thus eliminating the risk of intentional eavesdropping or information leakage caused by cross-frequency.

[0041] The communication protocol is specifically the HTTPS protocol. The HTTPS protocol is based on the HTTP protocol over SSL. It uses the HTTP protocol and adds an encryption and authentication layer between HTTP and TCP. During the HTTPS communication process, the client and the server will perform an SSL handshake, negotiate the security level, and establish a session key to ensure the secure transmission of the communication content.

Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
