Description

Technical Field

[0001] The present invention relates to the field of control of a multi-standard intercom system for mining, and in particular to a method, a device and a terminal for integrating a mining intercom system. Background Art

[0002] Intercom systems are widely used and popular. There are many types of intercom systems in coal mines, including PDT (Professional Digital Trunking), DMR (Digital Mobile Radio), ad hoc networks, and other non-standard types. Each type has its own private protocol and frequency, and cannot be interconnected. In response to this technical problem, a fusion intercom voice terminal is studied to achieve interconnection between different intercom systems, give full play to the advantages of each intercom system, achieve the best communication effect, and solve the communication problem in coal mines.

[0003] There are many types of existing intercom systems for mines. Intercom devices with different protocols cannot communicate with each other. The star networking system has a short communication distance but low cost and clear voice. The self-organizing network system has a high cost but can relay multiple times and has a long transmission distance. The leakage communication system requires a long leakage cable to communicate. In order to give full play to the advantages of each intercom system and make up for the shortcomings of each other, multiple types of intercom systems will be used in mines. However, each system is currently a separate system, which is easy to form information islands and lack of mutual communication means. In order to make up for the shortcomings of this technology, a fusion communication voice terminal is studied to realize the interconnection of different types of intercom systems.

[0050] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0051] The present disclosure provides a method for integrating a mine intercom system. Figure 1 As shown, the data transmission method includes the following steps:

[0052] 101. The fusion voice terminal interface of any intercom system can be connected to n interfaces. When the audio information accessed by the nth interface meets the conditions, the fusion voice terminal interface accesses the nth target audio signal, and at the same time encodes the nth target audio signal to form the nth target audio digital signal and transmits it to the nth ARM processor;

[0053] In one embodiment, the access audio information satisfies the condition, which means that the converged voice terminal interface accesses the nth target audio signal access range of unbalanced 600 ohms, the sound signal level range of -26 dBm to +12 dBm, and the frequency range of 100 Hz to 1500 Hz;

[0054] Alternatively, when the nth interface end is connected, it is detected that the COR (Call out Request) detection level signal changes in the range of 0V-5V; when the integrated voice terminal interface accesses the audio information and meets the conditions, the control instruction is output and transmitted to the nth ARM processor at the same time;

[0055] 102. The nth ARM processor detects that the audio input meets the above conditions, and transmits the nth target audio digital signal and the control instruction to the core ARM processor through interface A;

[0056] In one embodiment, the nth ARM processor detects the audio input sound frequency and signal amplitude range through the IO interface, and transmits the nth target audio digital decoding signal and control instructions to the core ARM processor;

[0057] Alternatively, after the nth ARM processor detects that the COR detection level signal is 0V-5V and the communication control PTT (Push to Talk) level is 0V-5V, the nth target audio digital decoding signal and the control instruction are transmitted to the core ARM processor.

[0058] After receiving the nth target audio digital signal and the nth ARM processor control instruction, the core ARM sends the control instruction to the other n-1 communication interfaces of the fusion voice terminal. At the same time, after decoding the nth target audio digital signal, the nth target audio digital decoded signal is obtained and transmitted to the n-1 ARM processor. The n-1 ARM processor transmits the nth target audio digital decoded signal to the fusion voice terminal.

[0059] After receiving the nth target audio digital decoding signal and control instruction, the core ARM transmits the control instruction to the other n-1 communication interfaces B of the converged voice terminal, so that the PTT level range corresponding to the n-1 interface is 0V to 5V, and at the same time sends the nth target audio digital decoding signal through the audio output interface.

[0060] 103. When the other n-1 communication interfaces B of the fusion voice terminal receive the control instruction and meet the PTT communication control preset value, the fusion voice terminal sends out the nth target audio digital decoding signal through the audio output terminal.

[0061] When the audio input of the converged voice terminal stops being connected, the COR level returns to normal, the core ARM processor releases the PTT communication control level, and the communication link returns to the idle state.

[0062] The disclosed embodiment provides a method for integrating a mine intercom system, which uses a set of integrated voice terminals to realize the integrated application of multiple types of intercom terminals corresponding to multiple standards, without the need to transform and upgrade the original system, thereby achieving the effect of integrated interconnection of multi-standard intercom systems and improving work efficiency.

[0067] When the first voice call is initiated, the audio input by the converged voice terminal is converted into a digital signal through digital coding. The first ARM processor detects the audio input sound frequency and signal amplitude range through the IO (I / O Input / Output) interface, which is unbalanced 600ohms, the sound signal level range is -26dBm to +12dBm, and the frequency range is 100Hz to 1500Hz.

[0068] Or after detecting that the COR level changes high or low, the COR level is 0V-5V, the ARM1 processor sends the voice digital signal and the control instruction to the core ARM. After the core ARM receives the voice digital signal and the ARM1 control instruction, it decodes the first voice digital signal to obtain the first voice digital decoding signal, and sends it. The ARM1 processor also sends the control instruction to the other four communication interfaces B2, B3, B4, and B5 of the fusion voice terminal, so that the corresponding PTT levels change. At the same time, ARM1 processes to obtain the first voice digital decoding signal through the audio output interface B, and the fusion voice terminal sends the first voice digital decoding signal at the voice output terminal 2 to the voice output terminal 5 respectively.

[0069] When the audio at the input stops, the COR level returns to normal, the core ARM releases the PTT control, and the communication link returns to the idle state.

[0070] The disclosed embodiment provides a method for integrating a mine intercom system, which uses a set of integrated voice terminals to realize the integrated application of multiple types of intercom terminals corresponding to multiple standards, without the need to transform and upgrade the original system, so as to achieve the effect of integrating and interconnecting the multi-standard intercom systems, reduce communication costs, and enable timely communication in various situations encountered in mines, thereby improving work efficiency.

Figure 3 The connection relationship can evolve into multiple intercom voice signal access, such as Figure 5 middle,

[0073] The third access end of the fusion voice terminal detects that there is voice information and meets the preset conditions (the access voice range is unbalanced 600ohms, the sound signal level range is -26dBm to +12dBm, and the frequency range is 100Hz to 1500Hz; or, the COR detection level signal change range detected when the nth interface is accessed is 0V-5V.), the third PTT communication control sends a control instruction to the ARM3 processor, and at the same time, the voice codec of the third interface encodes the third voice signal, obtains the third voice digital information and transmits it to the ARM3 processor, the ARM3 processor receives the third voice digital information and the communication control instruction and transmits them to the core ARM processor, the core processor obtains the third voice digital decoding signal after decoding and transmits it to the ARM3 processor, and at the same time sends the communication control instruction to the 1st, 2nd, 4th, and 5th B interfaces, and the 1st, 2nd, 4th, and 5th interfaces of the fusion voice terminal send 3 voice digital decoding signals.

[0074] The disclosed embodiment provides a method for integrating a mine intercom system, which uses a set of integrated voice terminals to realize the integrated application of multiple types of intercom terminals corresponding to multiple standards, without the need to transform and upgrade the original system, so as to achieve the effect of integrating and interconnecting the multi-standard intercom systems, reduce communication costs, and enable timely communication in various situations encountered in mines, thereby improving work efficiency.
