Non-safety power supply signal processor

Abstract

The invention relates to a non-safety power supply signal processor which comprises a shunting device, a rectifier, a step-down transformer and a wave filter, wherein the input end of the shunting device is the input end of a non-safety power supply signal, and the output end of the shunting device is the output end of an intrinsic safety communication signal; a middle port for outputting a direct current signal is arranged on the input end of the shunting device; the input end of the rectifier is connected with a middle port on the input end of the shunting device; the output end of the shunting device is connected with the input end of the step-down transformer; the output end of the step-down transformer is connected with the wave filter; and the output end of the wave filter is the output end of a direct current intrinsic safety power supply signal. The invention has the advantage of separating a carrier power supply signal input to a base station into the intrinsic safety communication signal and the intrinsic safety power supply signal, can be directly applied to the base station, enables the base station to achieve intrinsic safety without explosion isolation processing, greatly reduces the weight of the intrinsic safety base station, is convenient for installation and fixation, can improve the reliability of fixation to a great extent and greatly save the manufacture cost of an intrinsic safety base station because of omitting an explosion isolating shell, and is convenient for popularization and application.

Description

Non-safe power signal processor technical field The invention relates to a signal processor, in particular to a non-safe power signal processor for intrinsically safe processing of carrier power supply signals of wireless communication base stations used in coal mines and similar dangerous places with explosive mixtures. Background technique At present, the explosion-proof type of base station products used in coal mines adopts explosion-proof design. The power module and function module of the base station are placed inside the steel explosion-proof enclosure, and the remote power supply of the carrier is used to provide signals and power for the base station. Due to the heavy weight of the flameproof shell, the weight of the underground base station can reach about 25kg. However, the installation requirements of coal mine underground equipment usually require the base station to be suspended and fixed on the roadway wall. The heavy base station not only brings great incon...

Problems solved by technology

The purpose of the present invention is to solve the problem that the existing base station described in the background technology adopts the explosion-proof design, which leads to the heavy weight of the base station, which makes the installation and debugging of the base station inconvenient and the reliability of the fixation after installation is poor, and provides a solution for the base station.
