At the same time, the term "and / or" used in this specification includes any and all combinations of the relevant listed items.

[0037] In an exemplary embodiment, see Figure 1 The present application provides a portable intercom communication device for image transmission in a network-free scenario based on LPWAN autonomous network technology, referred to as an intercom communication device. The intercom communication device includes: a first communication module 1, a data processing module 2, and a second communication module 3.

[0038] Among them, the first communication module 1 is used to receive the first intercom data sent by the other intercom communication devices in the intercom group, and each intercom communication device in the intercom group is suitable for supporting LPWAN autonomous network technology and belongs to the same low-power wide area network, wherein the first intercom data includes at least one of voice data and image data.

[0039] The data processing module 2 is connected to the first communication module 1, and is used to determine the target intercom data from each first intercom data and process the target intercom data. The target intercom data is the intercom data sent by the intercom communication device in the same target intercom group in the intercom group as the intercom communication device.

[0040] The second communication module 3 is connected to the data processing module 2, and is used to connect to the communication device and to send the processed target intercom data to the communication device.

[0041] In this embodiment, the communication device can be a mobile phone. When the intercom communication device of the present application is used, the second communication module 3 can be connected to the mobile phone first. The first communication module 1 in the intercom communication device can form an intercom group by self-organizing the network through LPWAN (Low-Power Wide-Area Network) technology, so that each intercom communication device in the intercom group can be connected and communicated with each other, and there is no need to pre-configure a central node. Furthermore, the relevant technicians can obtain the information of each intercom communication device in the intercom group through the mobile phone, and divide the intercom group according to specific needs, and then send intercom data to members in the same intercom group, and receive intercom data sent to members in the same intercom group.

[0042] When the second communication module 3 is connected to the communication device, the first communication module 1 can receive the first intercom data sent by the remaining intercom communication devices in the intercom group, and send the received first intercom data to the data processing module 2. After receiving the first intercom data, the data processing module 2 can verify the first intercom data, and determine the target intercom data sent by the intercom communication device in the same target intercom group in the intercom group from each first intercom data to ensure that only the target recipient can read the intercom data.

[0043] Exemplarily, assuming that the intercom group includes intercom communication device a, intercom communication device b, intercom communication device c and intercom communication device d, each intercom communication device can be connected to the mobile application in the corresponding communication device through the second communication module, and the relevant technical personnel can configure the intercom group through the mobile application, for example: configure intercom communication device a, intercom communication device b and intercom communication device c in the same intercom group A, configure intercom communication device b, intercom communication device c and intercom communication device d in the same intercom group B, when intercom communication device b sends intercom data in intercom group A, intercom group A is the target intercom group, and the remaining intercom communication devices in the intercom group can receive the first intercom data sent by intercom communication device b. Taking intercom communication device a as an example, the first communication module in intercom communication device a receives the first intercom data. After receiving the first intercom data, the first intercom data can be verified, and after the verification is passed, the first intercom data can be determined as the target intercom data, and the target intercom data can be sent to the mobile application in the communication device through the second communication module, and then, the holder of the intercom communication device a can read the intercom data sent by the holder of the intercom communication device b; taking the intercom communication device d as an example, after receiving the first intercom data, the first communication module in the intercom communication device a can verify the first intercom data. Since the intercom communication device b sends the intercom data in the intercom group A, the intercom communication device d is not in the target intercom group, that is, the intercom group A, the verification of the first intercom data of the intercom communication device d will not pass, thereby ensuring that the holder of the intercom communication device d cannot read the intercom data sent by the holder of the intercom communication device b, thereby ensuring the security of the intercom data transmission.

[0044] The above-mentioned intercom communication device includes a first communication module, a data processing module and a second communication module, wherein the first communication module can receive the first intercom data sent by the remaining intercom communication devices in the intercom group, and each intercom communication device in the intercom group belongs to the same low-power wide area network. Based on the low-power wide area network, long-distance communication between each intercom communication device in the intercom group can be realized; after receiving the first intercom data sent by the remaining intercom communication devices in the intercom group, the first communication module can determine the target intercom data sent by the intercom communication devices in the same target intercom group in the intercom group from each first intercom data, and process the target intercom data, and then send the processed target intercom data to the communication device through the second communication module, such as a mobile phone, and read the target intercom data through the mobile phone. The intercom communication device of the present application can build its own communication network based on the low-power wide area network to realize long-distance communication and intercom, which is more in line with the actual use needs of relevant technical personnel.

[0045] In an exemplary embodiment, the data processing module is further used to receive an identification code sent by the communication device through the second communication module, and the identification code is used to determine the intercom data sent by the intercom communication device belonging to the same intercom group as the intercom communication device.

[0046] In the application, when a communication device is used to divide an intercom group in an intercom group, the communication device can send an identification code to the data processing module 2 through the second communication module 3. One intercom group shares one identification code. When the intercom communication device sends intercom data to the outside, it can carry the corresponding identification code. After receiving the first intercom data sent by other intercom communication devices, the intercom communication device can determine whether the first intercom data is the target intercom data according to the identification code carried in the first intercom data.

[0047] In an example, it is assumed that the intercom group includes intercom communication device a, intercom communication device b, intercom communication device c and intercom communication device d, intercom communication device a, intercom communication device b and intercom communication device c are in the same intercom group A, and the intercom communication device a, intercom communication device b and intercom communication device c in intercom group A share an identification code X; intercom communication device b, intercom communication device c and intercom communication device d are in the same intercom group B, and intercom communication device b, intercom communication device c and intercom communication device d share an identification code Y. When intercom communication device b sends intercom data in intercom group A, intercom group A is the target intercom group, and the intercom data carries identification code X. The remaining intercom communication devices in the intercom group can all receive the first intercom data carrying identification code X sent by intercom communication device b. Taking intercom communication device a as an example, after receiving the first intercom data, the first communication module in intercom communication device a can parse out the identification code X carried in the first intercom data. Since the identification code X carried in the first intercom data is the same as the identification code X of intercom communication device a, the first intercom data is verified, and the first intercom data can be determined as the target intercom data. The target intercom data is transmitted through the second communication module. The communication module sends the first intercom data to the mobile application in the communication device, and then the holder of the intercom communication device a can read the intercom data sent by the holder of the intercom communication device b; taking the intercom communication device d as an example, after receiving the first intercom data, the first communication module in the intercom communication device a can parse out the identification code X carried in the first intercom data. Since the identification code X carried in the first intercom data is different from the identification code Y of the intercom communication device d, the verification of the first intercom data by the intercom communication device d will not pass, thereby ensuring that the holder of the intercom communication device d cannot read the intercom data sent by the holder of the intercom communication device b, thereby ensuring the security of intercom data transmission.

[0048] In an exemplary embodiment, the data processing module 2 is further used to demodulate the first intercom data, obtain an identification code of the first intercom data, and determine the first intercom data whose identification code meets a preset condition as the target intercom data.

[0049] In this embodiment, after receiving the first intercom data, the first communication module 1 needs to convert the first intercom data of the analog signal into a digital signal, that is, demodulate the first intercom data so as to be able to perform subsequent processing. After converting the first intercom data of the analog signal into a digital signal, the data processing module 2 can read the identification code from the first intercom data, and verify whether the corresponding first intercom data is the target intercom data according to the identification code.

[0050] In an exemplary embodiment, see Figure 2The first communication module 1 includes: a communication antenna 11 and a self-organizing network unit 12. The self-organizing network unit 12 is used to support a low power wide area network LPWAN so that the intercom communication device belongs to an intercom group, and the communication antenna 11 is used to receive the first intercom data sent by the other intercom communication devices in the intercom group.

[0051] In the application, the self-organizing network unit 12 can automatically form and maintain a wireless network, namely an intercom group, so that the intercom communication devices in the intercom group can be connected and communicated with each other without the need to pre-configure a central node.

[0052] In an exemplary embodiment, see Figure 3 The intercom communication device of the present application further includes: a housing 4 , wherein the first communication module 1 , the data processing module 2 and the second communication module 3 are all arranged inside the housing 4 .

[0053] In this embodiment, the communication antenna 11 is also arranged inside the shell 4. By arranging the communication antenna inside the shell 4 to transmit and receive wireless signals, compared with the external antenna in the related technology, the communication antenna 11 is arranged inside the shell 4 in this application, which can improve the communication antenna 11. The anti-interference ability has better, thereby adapting to the complex electromagnetic environment in the professional power grid scenario.

[0054] The present application can further improve the performance and reliability of the wireless communication system by also arranging the communication antenna 11 inside the housing 4 and combining it with the self-organizing network unit 12. The built-in communication antenna 11 is responsible for the efficient transmission of signals, while the self-organizing network unit 12 is responsible for the automatic establishment and maintenance of the network, so that multiple intercoms can be seamlessly connected to form an efficient and reliable network.

[0055] In an exemplary embodiment, see Figure 4 The intercom communication device of the present application also includes: at least one electrical interface 5, the electrical interface 5 is respectively connected to the first communication module 1, the data processing module 2, and the second communication module 3, and the electrical interface 5 is used to connect to the communication equipment to power the first communication module 1, the data processing module 2, and the second communication module 3 through the communication equipment.

[0056] In the application, the electrical interface 5 is a Type-C power supply interface and / or a Lighting power supply interface. By setting the Type-C power supply interface and the Lighting power supply interface, the intercom communication device can be connected to the communication equipment, so that the communication equipment serves as an external power supply for the intercom communication device to power the intercom communication device. The present application reuses the communication equipment so that the communication equipment simultaneously serves as a power supply for the intercom communication device and enables the communication equipment to receive and display or play intercom data, thereby realizing the intercom communication device as a peripheral of the communication equipment. After the intercom communication device is connected to the communication equipment through the electrical interface 5, under the power supply of the communication equipment, the second communication module in the intercom communication device can be communicated with the communication equipment, and the first communication module can also be powered by the communication equipment to perform self-organizing networking and receive the first intercom data sent by other intercom communication devices in the intercom group, thereby realizing plug-and-play of the intercom communication device and the communication equipment, and improving the convenience of use.

[0057] In an exemplary embodiment, the second communication module 3 is also used to receive the second intercom data sent by the communication device, the data processing module 2 is also used to modulate and encrypt the second intercom data, and the first communication module 1 is also used to send the second intercom data after modulation and encryption to the remaining intercom communication devices in the intercom group.

[0058] In one example, the communication device has a display screen and may also be equipped with peripherals such as earphones and headphones. The intercom data transmitted between the intercom communication devices may be at least one of voice data, text data, and image data. In the application, after the communication device receives the target intercom data through the second communication module, if the target intercom data is voice data, the relevant technicians can receive the target intercom data through the earphone; if the target intercom data is text data and / or image data, the relevant technicians can read the target intercom data through the display screen.

[0059] Similarly, the communication device can send the second intercom data to the second communication module 3, and the second intercom data can be at least one of voice data, text data and image data. After receiving the second intercom data, the second communication module 3 can transmit the second intercom data to the data processing module 2, and the data processing module 2 can first encrypt the second intercom data. In one example, the data processing module 2 has multiple encryption technologies, and the multiple encryption technologies include at least part of AES256 encryption technology, WMT256 encryption technology, KET256 encryption technology, custom baseband protocol encryption technology and vocoder encryption technology to ensure the security and privacy of the communication content during the transmission process, prevent unauthorized personnel from intercepting or eavesdropping on the communication content, protect sensitive information from being leaked, and meet the communication security requirements of specific industries or fields. Afterwards, the data processing module 2 can modulate the encrypted second intercom data, convert the digital signal second intercom data into the analog signal second intercom data, so as to convert the second intercom data into a signal suitable for wireless transmission, and send it to the intercom group through the first communication module 1. It can be understood that the second intercom data carries an identification code so that the second intercom data can only be read by the other intercom communication devices belonging to the same target intercom group as the intercom communication device sending the second intercom data, so as to prevent the second intercom data from being intercepted or eavesdropped, thereby protecting sensitive information from being leaked.

[0060] In an exemplary embodiment, see Figure 5 The data processing module 2 includes: a modulation and demodulation unit 21 and an encryption and decryption unit 22.

[0061] The modulation and demodulation unit 21 is connected to the first communication module 1 and the second communication module 3 respectively, and is used for demodulating the first intercom data.

[0062] The encryption and decryption unit 22 is connected to the modulation and demodulation unit 21, the first communication module 1 and the second communication module 3 respectively, and is used to determine the target intercom data from each first intercom data after demodulation, and decrypt the target intercom data according to a preset encryption and decryption algorithm.

[0063] In a detailed embodiment, for an intercom communication device, the intercom data it receives is the first intercom data, and the intercom data it sends out is the second intercom data. When the first communication module 1 receives the first intercom data sent by the other intercom communication devices in the intercom group, the first communication module transmits the first intercom data to the modulation and demodulation unit 21 of the data processing module 2. The modulation and demodulation unit 21 can convert the first intercom data of the analog signal into a digital signal, that is, demodulate the first intercom data. After that, the encryption and decryption unit 22 can obtain the identification code from the demodulated first intercom data, and verify whether the corresponding first intercom data is the target intercom data according to the identification code. In the case of verifying that the first intercom data is the target intercom data, the encryption and decryption unit 22 can decrypt the target intercom data according to the preset encryption and decryption algorithm, and send the decrypted target intercom data to the communication device through the second communication module. The second communication module can be Bluetooth, and the communication device can be a mobile phone. Then, the holder of the intercom communication device can read the content of the target intercom data through the display screen and earphone of the mobile phone.

[0064] Then, the holder of the intercom communication device can send out intercom data through the communication device and the intercom communication device. Specifically, the communication device can send the second intercom data to the data processing module 2 through the second communication module 3. After receiving the second intercom data, the encryption and decryption unit 22 of the data processing module 2 can first encrypt the second intercom data, and then the modulation and demodulation unit 21 can modulate the encrypted second intercom data to convert the second intercom data of the digital signal into an analog signal suitable for wireless transmission, and send it to the intercom group through the first communication module. It can be understood that the second intercom data carries an identification code so that the second intercom data can only be read by the remaining intercom communication devices in the same target intercom group as the intercom communication device sending the second intercom data, so as to prevent the second intercom data from being intercepted or eavesdropped, thereby protecting sensitive information from being leaked.

[0065] In one example, the intercom communication device of the present application adopts the nationally produced, leading large-capacity narrowband wireless Internet of Things / LPWAN (low-power wide area network) communication technology. The working frequency band of the intercom communication device of the present application is 50MHz ~ 1040MHz, the bandwidth of the communication system is 125 kHz, the bandwidth of a single user is 2 ~ 125 kHz, the transmission rate is 0.1 kbps ~ 85.1 kbps, the receiving sensitivity is -150 dBm ~ -121 dBm, the duplex mode is TDD, and it supports high-concurrency random access based on mMIMO (TDMA + FDMA + SDMA). The intercom communication device of the present application has the characteristics of anti-interference and strong coverage. It can realize long-distance wireless intercom of 5~6km and has a flexible time slot structure. The time division technology adopted in the communication process supports point-to-point (multi-point) communication, supports LAN networking (including relay) and Mesh networking, realizes metropolitan-level wireless voice transmission applications, can realize one-to-many or many-to-many efficient voice transmission, and supports half-duplex and full-duplex intercom modes.

[0066] The modulation and demodulation unit of the present application has a built-in Codec circuit, which directly simulates the input and output of voice signals, and uses DPSFK and polarization code technology to modulate and demodulate the intercom data. The optional voice coding rate is 2.0Kbps~9.6Kbps, the optional forward error correction (FEC) rate is 50bps~7.2Kbps, and it supports DTMF detection and generation, voice activation detection (VAD) and comfort noise insertion (CNI). The encryption and decryption unit of the present application has five encryption technologies: AES256 encryption technology, WMT256 encryption technology, KET256 encryption technology, custom baseband protocol encryption technology and vocoder encryption technology, which ensures the security and privacy of communication content during transmission, prevents unauthorized personnel from intercepting or eavesdropping on communication content, protects sensitive information from being leaked, and meets the communication security needs of specific industries or fields.
