Problems solved by technology

When in use, the staff needs to switch between the receiving state and the sending state. If both parties are in the receiving state or in the sending state at the same time, they will not be able to communicate normally. Real-time voice intercom
[0003] At present, there are dedicated mining mobile phones, but it is necessary to lay a special wireless signal transceiver base station underground. This method is expensive, and the wireless signal is easily interfered, and there are signal blind spots.

no. 1 example

[0026] Such as figure 1 As shown, a mining intrinsically safe voice system includes an intrinsically safe power supply, a communication data transmission medium, a data processing unit and a voice device, and is characterized in that: it also includes an Ethernet switch unit, and the voice device connects to the Ethernet switch unit interface The set network transformer is connected with the Ethernet switch unit;

[0027] The data processing unit has a core processing unit, a microphone unit, a preamplifier unit, a hardware encoding unit, a hardware decoding unit, a loudspeaker unit, buttons, and a display unit; the Ethernet switch unit communicates with the core processing unit, and the buttons and The display unit is connected to the core processing unit, and the voice signal is input to the core processing unit through the microphone unit, the preamplifier unit, and the hardware encoding unit in turn, and the core processing unit outputs the signal through the hardware deco...

[0036] Such as figure 2 As shown, this embodiment is basically the same as the first embodiment, except that an echo cancellation circuit is connected between the hardware decoding unit and the pre-amplification unit. It can eliminate echo interference, ensure sound quality, and ensure that there is no interference in the case of two-way intercom.

[0037] The core processing unit adopts AVR ATmega64 single-chip computer, and configures corresponding data storage module and program storage module.

[0038] AVR ATmega64 single-chip computer greatly improves the function, precision and quality of the whole system, and has simple circuit, low failure rate, high reliability and low cost.

no. 3 example

[0040] Such as image 3 As shown, this embodiment is basically the same as the second embodiment, the difference is that there is a power amplification unit between the pre-amplification unit and the loudspeaker unit.

[0041] The signal output by the hardware decoding unit passes through the pre-amplification unit and then is transmitted to the loudspeaker unit for output through the power amplification unit, and the output current signal is further amplified. Because the underground mine is noisy, it can be guaranteed that the recipient can hear the instructions clearly.

[0042] As a further improvement, the Ethernet switch unit is equipped with an Ethernet network port and an optical fiber port; when the distance between the two voice devices is less than 100 meters, the Ethernet network port is selected; the distance between the two voice devices is not Choose the optical fiber port when the distance is less than 100 meters.

[0043] Each voice device has a fixed static...

Abstract

The invention relates to a voice conversation system and a voice device, and particularly relates to a mining intrinsic safety type voice system and a voice device thereof. The system comprises an intrinsic safety power supply, a communication data transmission medium, a data processing unit, an ethernet switch unit and voice devices. The data processing unit is provided with a core processing unit, a microphone unit, a pre-amplification unit, a hardware encoding unit, a hardware decoding unit, a power amplification unit, a loudspeaker unit and a button and display unit. The voice devices are communicated via an ethernet, and each voice device is allocated with one IP address. The switch unit supports a full duplex working mode. The mining intrinsic safety type voice device is the voice device adopting the system. A full duplex conversation between any two voice devices or the full duplex conversation with ground dispatching can be realized by the system and the voice device so that dispatching of working personnel under mines can be conveniently realized, and thus coal mine safety production efficiency can be enhanced.

Description

technical field [0001] The invention relates to a voice communication system and a voice device thereof, in particular to a mine intrinsically safe voice system and a voice device thereof. Background technique [0002] Coal mine safety production has always been a major issue in the coal mine field. With the development of modern communication technology, devices with voice communication functions have begun to be used in mines. At present, domestic mining voice devices generally transmit signals through audio. Most of the voice devices can only realize the broadcasting from the dispatching room above the mine to the underground, and some of them can realize half-duplex dialogue between two voice devices, that is, the voice device at the same time Only one of sending or receiving voice can be realized. When in use, the staff needs to switch between the receiving state and the sending state. If both parties are in the receiving state or in the sending state at the same time,...
