Embodiment 1
[0029] The system is mainly composed of ground broadcast master control equipment 1, intelligent intrinsically safe repeater 2, and underground broadcast substation 3. The intelligent intrinsically safe repeater 2 of the design scheme includes a server forwarding function module, which is used to realize the scheduling and broadcasting functions through the downhole handheld device when the ground server cannot be connected. There are two sets of services, high-level and low-level configuration, and seamless switching , improve system reliability. At the same time, the intelligent intrinsically safe repeater 2 adopts multi-port cascading technology, which can realize any topology of the network, such as a single ring topology. The system capacity of the repeater 2, each intelligent intrinsically safe repeater 2 can carry 20 units to broadcast 3 in underground broadcast sub-stations. At the same time, the expansion telephone can also form a single ring topology to improve reli...

The invention discloses a mining emergency broadcasting phonetic system. The mining emergency broadcasting phonetic system comprises ground broadcasting main-control equipment, at least one intelligent intrinsically-safe repeater and at least one underground broadcasting substation, wherein the ground broadcasting main-control equipment is used for acquisition and control dispatching of ground broadcasting voice; the intelligent intrinsically-safe repeaters are used for communication forwarding, audio encoding and decoding, compression and uncompression between the ground broadcasting main-control equipment and the underground broadcasting substations; the underground broadcasting substations are used for being connected with broadcasting expansion telephones to achieve phonic compression, uncompression and playback; and each intelligent intrinsically-safe repeater comprises a server forwarding functional module for achieving dispatching and broadcasting expansion functions through underground handheld equipment when the server forwarding functional module can not be connected with a ground server. The mining emergency broadcasting phonetic system provided with a backup battery can be continually used for 12 hours in case of power-off, and can be used for coal mine enterprises encountering sudden incidents to achieve efficient emergency broadcasting.
Description
technical field [0001] The invention relates to the field of security technology, in particular to a mining emergency broadcast voice system. Background technique [0002] Safety accidents in traditional coal mines occur frequently. Due to backward equipment, there is no effective emergency broadcasting and voice system. The original extensive personnel management mode in coal mines lacks the ability of underground personnel to respond to emergencies, cannot effectively protect the life safety of underground personnel, and cannot make timely and effective responses to accidents that may occur at any time. Contents of the invention [0003] The technical problem solved by the invention lies in how to improve the ability to deal with emergencies and how to make timely and effective responses to sudden accidents. [0004] In order to solve the above problems, the present invention provides a mine emergency broadcast voice system, comprising: [0005] Terrestrial broadcast m...
