Abstract
The utility model discloses a novel explosion-proof industrial mobile phone, including a front shell and a back shell which is sealed and fixed to the front shell. The novel explosion-proof industrial mobile phone is characterized in that an explosion-proof chamber formed by the front shell and the back shell is inside provided with a PCB, the PCB is provided with an RFID reader chip, the back shell is provided with an external antenna, and the external antenna is electrically connected with the RFID reader chip on the PCB. The explosion-proof industrial mobile phone is simple and solid in structure, good in sealing performance, can effectively prevent combustible gases into the explosion-proof chamber of the mobile phone shell, and prevent a circuit in the explosion-proof chamber producing sparks and further fire or explosion, being safe to use. Through the RFID reader chip set on the PCB and the external antenna on the back shell, a location is obtained by using RFID data registration, fine location is achieved and the strength of transmitted and received signals is enhanced.
Description
[technical field]
The utility model relates to a kind of explosion-proof communication apparatus, particularly a kind of new type explosion proof industry mobile phone.
[background technology]
To be material sharply become another kind of state and discharge the process of large energy from a kind of state through physics or chemical change in blast.Blast must possess three conditions: 1, explosive substance: can with the material of oxygen (air) reaction, comprise gas (such as hydrogen, acetylene, methane etc.), liquid (such as alcohol, gasoline etc.) and solid (such as dust, fibre dust etc.).2, oxygen, air.3, ignition source: comprise naked light, electric spark, mechanical spark, electrostatic spark, high temperature, chemical reaction, luminous energy etc.When explosive substance and airborne oxygen mix, when concentration is in the explosion limit scope, if there is ignition source, will blast.In inflammable and explosive place (such as the mining area, methane, coal-dust explosion mixture are arranged but in the environment of apodia with the corrosive gas that destroys metal and insulation and steam), the product that can become ignition source generally needs technological processing for explosion protection feature, not so can produce huge threat to people's lives and properties, and regular handset belongs to electric equipment, want in these inflammable and explosive places, to use, must do first technological processing for explosion protection feature.
[summary of the invention]
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of new type explosion proof industry mobile phone of the RFID of having positioning function is provided.
The purpose of this utility model is achieved in that and comprises that fore shell and sealing are fixed on the back cover on the fore shell, it is characterized in that: be provided with pcb board in the flame proof cavity that forms between described fore shell and the back cover, be provided with the rfid interrogator chip on the described pcb board, be provided with external antenna on the described back cover, the rfid interrogator chip that arranges on external antenna and the pcb board is electrically connected.
In the said structure, be provided with display screen and keyboard holder between described fore shell and the pcb board, described keyboard holder is fixed on the pcb board, and the both sides of keyboard holder upper end raise up respectively and are useful on the fixed part that display screen is installed; Mobile phone key is installed on the surface of keyboard holder by button FPC.
In the said structure, corresponding display location is set up and is provided with the observation port that matches with display screen on the described fore shell, covers the transparent glasses lens that is provided with for the protection of display screen on the described observation port.
In the said structure, described display screen is the LCD screen, and it is fixed on the face-piece or on the pcb board, lower end abutment is on the keyboard holder top.
In the said structure, be provided with camera and loudspeaker between described back cover and the pcb board, described loudspeaker are fixed on the inner surface of back cover by horn bracket.
In the said structure, described back cover is provided with battery compartment, and battery cover in battery compartment, and is fixed by screws in cell package on the back cover, and the corresponding battery compartment edge of battery cover is provided with waterproof apron between the position.
In the said structure, fix by screw between described fore shell and the back cover.
Compared with prior art, the beneficial effects of the utility model are: simple in structure firm, good seal performance prevents that effectively fuel gas from entering in the flame proof cavity of handset shell, avoid the spark that the circuit in the flame proof cavity produces and caused on fire or blast, used safety; By the external antenna that the rfid interrogator chip that arranges at pcb board and back cover arrange, utilize the registration of RFID data to draw the position, realize small location, and strengthened the intensity of sending and receiving signal.
