Explosion-proof remote wireless data acquisition substation RTU internally equipped with solar cell

Abstract

The invention discloses an explosion-proof remote wireless data acquisition substation RTU internally equipped with a solar cell. The explosion-proof remote wireless data acquisition substation RTU comprises a box body and a box cover, wherein the box body comprises an infrasonic sensor, a pre-amplifier, a safety barrier, data acquisition equipment, a safety switch, a charge control module and a battery; the box cover comprises a cover body, a gland, a transparent piece and a solar panel; the infrasonic sensor receives an infrasonic signal in a pipeline in real time and converts the infrasonic signal into an electric signal; the pre-amplifier processes the electric signal and transmits the signal to the data acquisition equipment; the data acquisition equipment converts the electric signal into data and sends the acquired infrasonic signal to a data terminal; the data acquisition equipment is powered by the battery, and luminous energy is obtained from solar energy, so that the whole substation works continuously, safely and effectively without environmental influence. The substation is explosion-proof and guarantees safety when used in hazardous environments with other explosive gases other than coal mine gas, and unnecessary potential safety hazards are reduced.

Description

technical field [0001] The invention relates to a flameproof remote wireless data acquisition substation RTU with a built-in solar cell. The flameproof remote wireless data acquisition substation RTU can be used in a dangerous environment of explosive gases other than coal mine gas. Detect the leakage signal of various conveying medium pipelines such as oil transportation and gas transportation. Background technique [0002] At present, the mileage of pipelines in my country has reached more than 100,000 kilometers. As time goes by, corrosion and perforation of pipelines, leakage pollution, blockage and bursting of pipelines may occur, causing heavy losses of life and property. In order to provide timely and effective measures for accidents, it is necessary to collect acoustic signals in the pipeline in real time and make timely and effective early warning of leakage signals. However, since the environment where the pipeline is located is usually a dangerous environment of ...

AI Technical Summary

Problems solved by technology

However, since the environment where the pipeline is located is usually a dangerous environment of explosive gases other than coal mine gas, there are strict requirements on the safety of the equipment used in this area, and the minimum standard is the explosion-proof level. According to this safety standard, when the equipment fails, it may cause an explosion, causing huge losses to the safety of personnel and national property.

[0003] At present, there are many explosion-proof equipment for pipeline leakage detection in the world, mainly including non-rechargeable sealed battery type and safe area power supply type. Due to the limitation of power supply mode, the application of these equipment is not wide, and it is necessary to replace the battery regularly or repair the equipment. There are requirements for the installation location, which indirectly leads to the inability to install equipment at some key detection points, resulting in blind spots in the entire leak detection system.
