Wireless monitoring system of oil outlet relief valve of oil tank truck (TMS system)

Abstract

A fully-automatic wireless monitoring system (TMS system) which can perform non-artificial interference of an oil outlet relief valve of an oil tank truck. The invention is a wireless monitoring system developed by using sensor technology, embedded computing technology, modern network and wireless communication technology, and distributed information processing technology. A monitoring element of the system is directly and rigidly connected to a monitored valve by a shaft coupling and a valve stem. The monitoring element measures the angle displacement of the valve stem; data collection, recording, storage, wireless transmission, data uploading, and report formation are performed by the TMS system; and an alarm is provided by the TMS management software finally. Problems of easy forgery and easy substitution of currently-used mechanical lead sealing, artificial intervention of electronic lead sealing, unreliability of information collecting points, and dependence of power supply by vehicle power supply are prevented. Non-artificial interference of overall monitoring is realized, and the authenticity, reliability and integrity (no lost data) of the recorded data are ensured; therefore the generation of invalid oil stealing behaviors from oil tank trucks is effectively prevented. All the hardware forming the TMS system passes the ATEX explosion-proof certification, and can ensure the safe utilization of the system in dangerous areas.

Description

Technical field [0001] The patent of the present invention relates to a wireless monitoring system for an oil port discharge valve of a tank truck composed of wireless sensor technology, embedded computing technology, modern network and wireless communication technology, and distributed information processing technology. In particular, it can effectively prevent oil tank trucks from stealing oil illegally. Background technique [0002] At present, there are mainly two types of known oil tanker monitoring means: mechanical seals and electronic seals. [0003] Mechanical lead seals have poor anti-counterfeiting performance because of their simple structure and sealing marks, and are easy to copy. It is impossible to fundamentally solve the problem of being counterfeited or replaced by the same type of seal. The same type of seal is easy to obtain from internal managers, manufacturers or the market, and it is relatively easy to imitate by general technological means. [0004]...

Problems solved by technology

Similarly, its closing and unlocking actions still require personnel to operate, which increases a lot of uncertain factors caused by human intervention.

In addition, since the system needs the power supply on the tank truck, once the power is lost, the system will be paralyzed and cannot be monitored.
