Problems solved by technology

(3) There is basically no contact and interaction between the systems: the communication systems that have been built in coal mines are different due to different construction times, different technical methods, and various reasons that actually existed during construction. System "islands" where systems do not communicate and interact with each other
Moreover, several communication systems may exist at the same time in a mine, but each system is independent of each other, and cannot communicate and communicate at critical moments, lacks unified dispatching and command, and does not meet the requirements of the Safety Supervision Bureau's "Coal Mine Emergency Communication Guarantee System"

Embodiment 1

[0024] Embodiment one: see figure 1 , figure 2 . The mine emergency communication system of the present invention includes an integrated command and rescue call center server, an IP telephone exchange (IPPBX), a voice gateway, a dispatch switch, an underground dispatching amplified telephone, an underground amplified broadcast telephone, the integrated command and rescue call center server, an IP The telephone switch and the voice gateway are interactively connected through an industrial Ethernet switch, the voice gateway is connected to the dispatching switch at the same time, and the dispatching switch is connected to the underground IP telephone switch, the voice gateway adopts a mining integrated IP voice access gateway, and the mining integrated The IP voice access gateway adopts a 32-bit embedded microprocessor, and the protocol conversion address of the microprocessor is connected to the system interface module. The field bus protocol conversion module (RS485 or CAN...

Embodiment 2

[0027] Embodiment two: see figure 1 , figure 2 , image 3 , Figure 4 , The mining emergency communication system of this embodiment is different from Embodiment 1 in that it further illustrates a kind of underground broadcast telephone structure adopted.

[0028] see image 3 , the downhole broadcast telephone includes a user interface circuit and a media stream IP processing digital circuit, and the media stream IP processing digital circuit receives the data transmitted from the analog bus connector, and outputs it to the A / D conversion module and the A / D conversion module after being processed by the CPU. Codec MC14LC5480, finally through the power amplifier to the loudspeaker to realize the loudspeaker broadcast; the digital voice signal of the digital circuit conversion port of the media stream IP processing through the EP2C8Q208C8 type FPGA chip microprocessor, unpacking and extracting the voice data to send Enter the VS1003B to decompress and decode it, and then ...

Embodiment 3

[0031] Embodiment three: see figure 1 , figure 2 , image 3 , Figure 4 The mine emergency communication system of this embodiment is different from embodiment one or embodiment two in that it contains a PHS wireless communication system, a PHS switch is connected to an Ethernet switch through a voice gateway, and wireless base stations are provided on the well and underground. The PHS realizes wireless communication through the wireless base station, and the underground PHS uses an intrinsically safe PHS.

Abstract

The invention relates to a mine communication system, in particular to an emergency communication support system of coal mines. The emergency communication support system comprises an integrated command rescue call center server, an IP (Internet Protocol) telephone switchboard and an voice gateway, which are interactively connected through Ethernet, wherein the voice gateway is simultaneously connected to a dispatching switchboard, an integrated IP voice access gateway for mine is adopted as the voice gateway, a 32-bit embedded microprocessor is adopted for the voice access gateway, a protocol conversion address of the microprocessor is connected with a system interface module, a serial port of the microprocessor is connected with a field bus protocol conversion module, the field bus protocol conversion module is connected with an underground dispatching amplified phone, an MAC (Media Access Control) address of the microprocessor is connected with a network module, and the microprocessor is connected with an Ethernet switchboard through the network module. The microprocessor is provided with a corresponding data interface for connecting an optical fiber transmission module, the microprocessor is accessed to an underground industrial optical fiber ring net through the optical fiber transmission module, and the underground loud-speaking phone is accessed to the underground industrial optical fiber ring net through a converter. According to the mine communication system disclosed by the invention, a difficult problem of the speed bottleneck in the wide-band network underground communication of a mine area is solved, and a way is paved for networking and informatizing of a mine monitoring system.

Description

technical field [0001] The invention relates to a mine communication system, in particular to a mine emergency communication guarantee system. Background technique [0002] Coal is the main energy source in my country, accounting for about 70% of the primary energy. About 95% of my country's coal mines are underground mines, and the mining conditions are complex. With the increase of mining depth, disasters such as coal mine gas, flooding, and rock bursts are becoming more and more serious. It is easy to cause a major accident. In recent years, the "12.7" particularly serious gas explosion accident at the Liuguantun Coal Mine in Tangshan, Hebei Province killed 108 people; the "12.5" particularly serious gas explosion accident at the Ruizhiyuan Coal Mine in Linfen, Shanxi Province killed 105 people; The major gas explosion accident killed 78 people; the "9.8" extremely serious gas explosion accident at Xinhua No. 4 Mine in Pingdingshan City, Henan Province killed 79 people; t...
