Abstract
The invention discloses an explosion-proof IP telephone terminal. The explosion-proof IP telephone terminal comprises a computer server, a routing board, a voice board, a keyboard, a sound amplification board, a microphone and an explosion-proof camera. According to the adopted technical scheme, an explosion-proof cavity is adopted: a single board in the cavity is partitioned into the voice board, the sound amplification board and the routing board; the voice board is used for converting a pickup signal in the microphone into a digital signal and converting the digital signal into an Ethernet packet to be transmitted to the routing board through an AD chip; meanwhile, an external Ethernet packet transmitted by the routing board is converted into a digital signal to be transmitted to a DA signal and converted to sound, and the sound is transmitted to the microphone or the sound amplification board to realize sound amplification; the routing board is used for transmitting the Ethernet packet through an optical fiber, and receiving the Ethernet packet transmitted by the optical fiber; the sound amplification board is used for realizing a sound amplification function; and a digital signal of the explosion-proof camera (7) is also transmitted to a computer server (1) through the routing board (2). The explosion-proof IP telephone terminal has the advantages of high electromagnetic interference resistance, long transmission distance, simple connection way and flexibility in control.
Description
Technical field
The present invention relates to a kind of telephone terminal, particularly the explosion-proof IP phone terminal of one, belongs to communication technique field.
Background technology
Analog communication mode electromagnetism interference under existing explosion gas environment is poor, and transmission range is short, and only in several kilometers, and connected mode is complicated, and between each explosion-proof videotelephone station, wiring trouble, controls dumb.In addition, general explosion-proof public address system, does not have amplify technology and video monitoring of realization to combine in real time.
Summary of the invention
For solving prior art problem, the invention discloses a kind of explosion-proof IP phone terminal, comprise computer server, route plate, voice plate, keyboard, the plate that amplifies, microphone and Explosionproof camera, adopt explosion-resistant enclosure, be connected with server by the simple optical fiber mode of handing in hand between the terminals, after voice signal is changed by modulus (AD), by ether IP data packet transmission to server or next terminal.
The technical solution adopted in the present invention is: adopt explosion-proof cavity; In cavity veneer be divided into voice plate, the plate that amplifies, route plate; Explosionproof camera is connected with voice plate, and the two realizes converting the signal of the pickup signal in microphone and Explosionproof camera to digital signal by A/D chip, then digital signal is converted to Ethernet bag and be sent to route plate; Simultaneously also convert the external ethernet packet that route plate is sent here to digital signal, send to DA signal, convert sound to, deliver to microphone or the plate that amplifies realizes amplifying; Route plate realizes Ethernet bag to be sent by optical fiber, also receives the Ethernet bag that optical fiber is sent here simultaneously; The plate that amplifies realizes sound amplification function.
Between the explosion-proof terminal of the present invention and between explosion-proof terminal and computer server, adopt a Fiber connection.Transmission means is full Ethernet data packet mode; Server can monitor each terminal call state; Point-to-point call, multicast, broadcast, warning, sound amplification function can be realized.
Beneficial effect: the present invention is scientific and reasonable for structure, electromagnetism interference is strong, and transmission range is long, and connected mode is succinct, controls flexibly.

Embodiment
By reference to the accompanying drawings, the present invention is described in further details.
As shown in the figure, the invention provides a kind of explosion-proof IP phone terminal, comprise computer server (1), route plate (2), voice plate (3), keyboard (4), the plate that amplifies (5), microphone (6) and Explosionproof camera (7), adopt explosion-resistant enclosure, be connected with server by the simple optical fiber mode of handing in hand between the terminals, after voice signal is changed by modulus (AD), by ether IP data packet transmission to server or next terminal.
The technical solution adopted in the present invention is: adopt explosion-proof cavity; In cavity, veneer is divided into voice plate (3), the plate that amplifies (5), route plate (2); Explosionproof camera (7) is connected with voice plate, pass through A/D chip, realize converting the signal of the pickup signal in microphone and Explosionproof camera (7) to digital signal, then digital signal is converted to Ethernet bag and be sent to route plate (2); Simultaneously also convert the external ethernet packet that route plate (2) is sent here to digital signal, send to DA signal, convert sound to, deliver to microphone (6) or the plate that amplifies (5) realizes amplifying; Route plate (2) realizes Ethernet bag to be sent by optical fiber, also receives the Ethernet bag that optical fiber is sent here simultaneously; The plate (5) that amplifies realizes sound amplification function; The digital signal of camera (7) in addition, is also sent to server by route plate (2).
Between the explosion-proof terminal of the present invention and between explosion-proof terminal and computer server, adopt a Fiber connection.Transmission means is full Ethernet data packet mode; Computer server (1) can monitor each terminal call state; Point-to-point call, multicast, broadcast, warning, sound amplification function can be realized, by camera (7), realize video monitoring function.
Above-mentioned embodiment is only for example of the present invention is clearly described, and the restriction not to execution mode.For those of ordinary skill in the field; can also make other changes in different forms on the basis of the above description; here exhaustive without the need to also giving all execution modes, and thus the apparent change of amplifying out or variation be still in protection scope of the present invention.
