Description

Technical Field

[0001] This invention relates to the field of radio communication technology, specifically to a walkie-talkie and its anti-crosstalk method. Background Technology

[0002] Skiing is a popular outdoor sport that can be enjoyed both competitively and as a recreational activity. Around the world, skiing has become a popular leisure and social activity, attracting a large number of enthusiasts. To facilitate communication and coordination among skiers, walkie-talkies are playing an increasingly important role in the sport. Walkie-talkies help skiers communicate promptly, exchange important information, and improve both safety and enjoyment.

[0003] Walkie-talkies in the current technology are generally divided into analog walkie-talkies and digital walkie-talkies. Digital walkie-talkies use digital signal processing technology for signal transmission and have more secure and private communication functions. However, digital walkie-talkies are expensive, so analog walkie-talkies are usually used in skiing.

[0004] Currently, analog walkie-talkies on the market typically require manual setting of frequencies and sub-tone codes. This manual setting process is cumbersome and time-consuming. Furthermore, within a certain range after setting, frequency crosstalk issues can easily occur, affecting the user experience. Summary of the Invention

[0005] In view of the above-mentioned deficiencies in the prior art, the present invention provides a wireless walkie-talkie and a method for preventing crosstalk, so as to solve at least one of the above-mentioned technical problems.

[0006] Specifically, a method for preventing crosstalk in walkie-talkies includes the following steps:

[0007] The system locates the intercom position of the walkie-talkie using a positioning system, and sends the intercom position and the intercom configuration request of the walkie-talkie to a preset server.

[0008] After the server receives the intercom configuration request, it parses the maximum communication range of the intercom and determines whether there is an intercom area defined around the intercom location.

[0009] If it does not exist, a circular area covering the maximum communication range is defined as the intercom area, with the intercom location as the center and a preset distance as the radius.

[0010] The intercom configuration information that the server has sent to other intercoms in the intercom area within a preset time period is filtered out to obtain an intercom configuration information set.

[0011] When the set of intercom configuration information does not completely cover all intercom configuration information, the intercom configuration information that is not in the set of intercom configuration information is filtered out to obtain the set of available intercom configuration information.

[0012] The server selects intercom configuration information from the available information set and configures it into the intercom via a wireless transmission module.

[0013] In the above technical solution, preferably, after obtaining the intercom location:

[0014] If there is an intercom area defined around the intercom location, the server determines whether the intercom area is larger than the maximum communication range.

[0015] If so, the server does not define an intercom area;

[0016] If not, it is considered that there is no intercom area defined around the intercom location.

[0017] In the above technical solution, preferably, when the intercom configuration information set completely covers all intercom configuration information:

[0018] The intercom configuration information provided by the server is given in a preset order.

[0019] In the above technical solution, preferably, when the walkie-talkie does not have the positioning system installed:

[0020] The location of the intercom is located by calling the positioning system of the external intelligent electronic device through the APP in the external intelligent electronic device.

[0021] The external smart electronic device sends the intercom configuration request and the intercom location to the server.

[0022] After receiving the intercom configuration request, the server selects intercom configuration information from the available information set and sends it to the external smart electronic device.

[0023] The intercom configuration information is configured into the intercom via the near-field wireless module in the external intelligent electronic device.

[0024] In the above technical solutions, preferably, the near-field wireless module includes: a Bluetooth module, a WIFI module, or an NFC module.

[0025] In the above technical solution, preferably, when the positioning system is installed in the walkie-talkie:

[0026] The location of the walkie-talkie is determined by the positioning system in the walkie-talkie.

[0027] The walkie-talkie sends the walkie-talkie configuration request and the walkie-talkie location to the server via the wireless transmission module in the walkie-talkie.

[0028] After receiving the intercom configuration request, the server selects intercom configuration information from the available information set and configures it into the intercom via the wireless transmission module.

[0029] In the above technical solutions, preferably, the wireless transmission module includes: an IoT module, a LoRa module, or a UV standard module.

[0030] In the above technical solution, preferably, the intercom configuration information includes: frequency point and / or sub-audio code, wherein the frequency point belongs to the U / V band.

[0031] The present invention also provides a wireless walkie-talkie for implementing a wireless walkie-talkie anti-crosstalk method as described in any of the above technical solutions, including a walkie-talkie module, a near-field wireless module, a main control module, and a power management module for power supply.

[0032] The intercom module includes: an intercom chip, a wireless communication device, and an electro-acoustic converter. The intercom chip is connected to the wireless communication device and the electro-acoustic converter, and is used to decode the signals received by the wireless communication device and to encode the electrical signals output by the electro-acoustic converter and transmit them through the wireless communication device.

[0033] The near-field wireless module is used to configure the intercom configuration information into the intercom.

[0034] In the above technical solution, preferably, it also includes a wireless transmission module and the positioning system;

[0035] The positioning system is used to locate the intercom location, and the wireless transmission module is used to send the intercom configuration request and the intercom location of the intercom to the server.

[0036] In summary, the wireless walkie-talkie and its anti-crosstalk method of the present invention have the following beneficial effects: The present invention avoids crosstalk phenomena that occur when the walkie-talkie configuration is the same as that of other walkie-talkies, prevents communication with other walkie-talkies, and improves the privacy of walkie-talkie calls within the team. Simultaneously, by wirelessly transmitting the walkie-talkie configuration information, the user is spared the need to manually set the configuration, reducing the difficulty of operating the walkie-talkie, saving operation time, and improving the user experience.

[0050] Example 1

[0051] This embodiment provides a method for preventing crosstalk in walkie-talkies, avoiding interference with signals from other walkie-talkies, such as... Figure 1 As shown, the specific steps include:

[0052] Step 101: Locate the intercom position of the walkie-talkie using the positioning system, and send the intercom position and the intercom configuration request of the walkie-talkie to the preset server.

[0053] The intercom location is the location of the positioning system, or it can be a location selected by the user on a map according to their needs. The preset server can be a network server set up in the cloud or a ground service center. In one specific embodiment, the ground service center and the network server are used in conjunction. The positioning system includes: GPS (Global Positioning System), BDS (China's BeiDou Navigation Satellite System), or GLONASS (Russia's Global Navigation Satellite System).

[0054] Step 102: After the server receives the intercom configuration request, it parses the maximum communication range of the intercom and determines whether there is an intercom area defined around the intercom location.

[0055] The maximum communication range of a walkie-talkie is typically 2-7 km in radius, varying depending on the usage scenario. In open environments, the communication range can be even greater. Walkie-talkie configuration information includes the frequency and sub-tone code. The frequency refers to the radio wave frequency used; different frequency bands have different usable frequency ranges. Commonly used walkie-talkie frequency bands are VHF (Very High Frequency) and UHF (Ultra High Frequency), also known as the U / V band. The number of usable frequencies in the U / V band is limited, generally 16-20. When manually setting frequencies, crosstalk can easily occur. Users need to select the appropriate frequency to avoid interference with other wireless devices. Sub-tone code (CTCSS) is an encoding method that transmits audio signals using a specific frequency encoding method. Only walkie-talkies with the same encoding method can receive the signal. Sub-tone codes effectively reduce interference between different users, improving the confidentiality and stability of the walkie-talkie. Users can also set multiple sub-tone codes as needed to achieve wireless communication between different groups. In one specific embodiment, parameters such as frequency point and sub-tone code are set simultaneously to reduce interference with other wireless devices.

[0056] Step 103: If it does not exist, define a circular area with the intercom location as the center and a preset distance as the radius to cover the maximum communication range as the intercom area.

[0057] Preferably, the preset distance is 10 km, meaning the intercom area is a circle with a radius of 10 km centered on the intercom position. In other embodiments, the intercom area can be changed according to actual needs and can be triangular or square, etc.; the range of the intercom area is larger than the communication range of the walkie-talkie to reduce signal interference from other walkie-talkies. For example, when the maximum communication range of the walkie-talkie is a circle with a radius of 3 km, the intercom area is a circle with a radius of 10 km. If the intercom area is a circle with a radius less than 3 km, crosstalk may occur when the walkie-talkie moves outside the intercom area while communicating with other walkie-talkies.

[0058] Step 104: Filter out the intercom configuration information that the server has sent to other intercoms in the intercom area within a preset time period, and obtain the intercom configuration information set.

[0059] Step 105: When the intercom configuration information set does not completely cover all intercom configuration information, filter out the intercom configuration information that is not in the intercom configuration information set to obtain the available intercom configuration information set.

[0060] Step 106: The server selects intercom configuration information from the available information set and configures it into the intercom via the wireless transmission module.

[0061] Preferably, the preset time is 24 hours, meaning that the intercom configuration information provided by the server is not repeated within 24 hours in the intercom area, and the preset time can be changed according to needs.

[0062] When the server's intercom configuration information is insufficient:

[0063] The server provides intercom configuration information in a preset order. Preferably, the preset order is arranged in chronological order, meaning the server remembers each set of intercom configuration information. When the server lacks sufficient intercom configuration information, it provides the first set of intercom configuration information, then the second, the third, and so on, until the last set returns to the first set, and so on, in a loop.

[0064] like Figure 2 As shown, when the walkie-talkie does not have a positioning system, the following steps are included (201, 202, 203, and 204):

[0065] Step 201: Use the APP in the external smart electronic device to call the positioning system of the external smart electronic device to locate the intercom location.

[0066] Preferably, external smart electronic devices include electronic devices with intelligent systems and positioning systems, such as mobile phones, smartwatches, and laptops.

[0067] Step 202: Send an intercom configuration request and intercom location to the server via an external smart electronic device.

[0068] Step 203: After the server receives the intercom configuration request, it selects intercom configuration information from the available information set and sends it to the external smart electronic device.

[0069] Step 204: Configure the intercom configuration information into the intercom via the near-field wireless module in the external smart electronic device.

[0070] Near-field wireless modules include: Bluetooth modules, WIFI (wireless network) modules, or NFC (near-field communication) modules. Near-field wireless modules belong to the category of wireless transmission modules.

[0071] Figure 3 As shown, when the positioning system is installed in the walkie-talkie, the following steps (301, 302, and 303) are included:

[0072] Step 301: Locate the location of the walkie-talkie using its positioning system;

[0073] Step 302: Send a walkie-talkie configuration request and walkie-talkie location to the server via the wireless transmission module in the walkie-talkie;

[0074] Step 303: After the server receives the intercom configuration request, the server selects intercom configuration information from the available information set and configures it into the intercom via the wireless transmission module.

[0075] Preferably, the wireless transmission module includes: a LoT (cellular data, such as 2G / 3G / 4G / 5G, etc.) module, a LoRa (long-range wireless transmission technology) module, or a UV (ultra-high frequency and very high frequency) standard module.

[0076] Example 2

[0077] This invention also provides a walkie-talkie for implementing any of the above-mentioned methods for preventing crosstalk in walkie-talkies, such as... Figure 4 As shown, it includes an intercom module, a near-field wireless module, a main control module, and a power management module for power supply. The near-field wireless module is used to configure intercom configuration information into the intercom.

[0078] The intercom module includes an intercom chip, a wireless communication device, and an electro-acoustic transducer. Preferably, the wireless communication device is an antenna, and the electro-acoustic transducer is a speaker and a microphone. The intercom chip includes an encoder and a decoder. The intercom chip connects to the wireless communication device and the electro-acoustic transducer, and is used to decode the signals received by the wireless communication device, and to encode the electrical signals output by the electro-acoustic transducer before transmitting them through the wireless communication device.

[0079] Preferably, the walkie-talkie in Embodiment 2 further includes a wireless transmission module and a positioning system. The positioning system is used to locate the preset intercom location, and the wireless transmission module is used to send an intercom configuration request and the preset intercom location to the server.

[0080] The present invention provides a wireless walkie-talkie and its anti-crosstalk method, which has the following beneficial effects: The present invention avoids crosstalk caused by identical walkie-talkie configuration information with other walkie-talkies within the communication area, preventing the overhearing of other walkie-talkie conversations and the leakage of conversation information from the user's own walkie-talkie, thus improving the privacy of walkie-talkie calls. Simultaneously, by wirelessly transmitting the walkie-talkie configuration information, the user is spared the need for manual configuration settings, reducing the operational difficulty of the walkie-talkie, saving operation time, and improving the user experience.

[0081] The above is a detailed description of the preferred embodiments of the present invention. However, the present invention is not limited to the embodiments described.

All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
