High-stability positioning device for transportation of domestic liquefied natural gas tank

Abstract

The invention discloses a high-stability positioning device for transportation of domestic liquefied natural gas, and belongs to the technical field of positioning and monitoring of LNG (liquefied natural gas) transportation vehicles, the high-stability positioning device comprises an anti-explosion solar panel and an anti-explosion box consisting of a box body and a cover plate, the anti-explosion solar panel and the anti-explosion box are both mounted on an LNG vehicle, a lead-acid battery, a PWM intelligent controller and a GPS / GPRS dual-mode positioning module are arranged in the explosion-proof box, a plate, sleeved with an explosion-proof threading pipe, of the outer surface of the explosion-proof solar panel penetrates through and extends into the box body through a wire and is connected with a solar wiring port of the PWM intelligent controller, and the lead-acid battery is connected with a storage battery wiring port of the PWM intelligent controller; and the problem that a traditional GPS positioning module needs external power supply is solved, sufficient energy supply can be guaranteed through the photovoltaic power generation technology, meanwhile, a lead-acid battery is arranged to serve as energy storage and buffering equipment, and under the severe conditions such as cloudy days, at least energy used in cloudy and rainy days can be stored.

Description

technical field [0001] The invention belongs to the technical field of positioning and monitoring of LNG transport vehicles, and in particular relates to a high-stability positioning device for filling and transporting liquefied natural gas for domestic use. Background technique [0002] LNG is liquefied natural gas, the main component is methane, which is recognized as the cleanest fossil energy on earth. Colorless, odorless, non-toxic and non-corrosive, its volume is about 1 / 625 of the same volume of gaseous natural gas, and the quality of liquefied natural gas is only about 45% of the same volume of water. Purification treatment, after a series of ultra-low temperature liquefaction, transported by liquefied natural gas ships. Liquefied natural gas causes very little air pollution after combustion and releases a lot of heat, so liquefied natural gas is a relatively advanced energy source. Liquefied natural gas is compressed and cooled to its freezing point (-161.5°C) and ...

Problems solved by technology

[0004] 1. The GPS module draws power from the car body. If it is idle for a long time, it will easily cause the battery to lose power, which will affect the monitoring operation and vehicle driving. Moreover, the GPS module can be removed at any time, and there are loopholes in management

[0005] 2. The GPS module is installed separately for power supply. In order to achieve the rainproof effect, this method is generally installed at the bottom of the vehicle, which will cause large GPS positioning deviation or even positioning failure, and the battery needs to be replaced regularly
