Description

Personnel positioning early warning terminal based on UWB technology for open pit coal mine

Technical Field

The utility model relates to a location early warning device technical field specifically is a personnel location early warning terminal based on UWB technique in opencut coal mine.

Background

The UWB technology is a wireless carrier communication technology, which does not use a sinusoidal carrier, but uses nanosecond-level non-sinusoidal narrow pulses to transmit data, and thus occupies a wide frequency spectrum. UWB is essentially a carrierless spread spectrum technique with very low duty cycle impulse as the information carrier by direct modulation of impulse pulses with very steep rise and fall times. The typical UWB transmits bursts directly, no longer having the traditional concept of intermediate frequency and radio frequency, when the transmitted signal can be seen as either a baseband signal (in the case of conventional radio) or a radio frequency signal (from the spectral content of the transmitted signal). The UWB technology is commonly used at present to carry out positioning early warning on an open pit coal mine so as to prevent accidents from happening, and a positioning early warning terminal adopting the UWB technology is needed.

The positioning early warning terminal that adopts at present is more similar to the cash dispenser of bank, can have the computer that has early warning locate function to realize early warning information's demonstration and alarming function at the internally mounted of the cabinet body, and because this terminal equipment generally all installs and use in the open air when in-service use, and opencut coal mine environment is comparatively abominable, can meet often that strong convection strong wind weather extremely easily leads to device itself to appear empting, and the display screen part receives the interference influence in-service use of dust easily simultaneously.
