CN102147950A - Antitheft and anti-leakage monitoring method and system for fuel tank trunk - Google Patents

Abstract

The invention relates to an antitheft and anti-leakage monitoring method and an antitheft and anti-leakage monitoring system for a fuel tank trunk. In the method and system, when the fuel tank trunk carries fuel or chemicals, fuel or chemical leakage or theft can be found instantly by acquiring data such as pressure and temperature of the fuel tank vehicle, recording and analyzing the data and giving a remote alarm. Thus, the atmosphere is protected against pollution and the benefit of the cargo owner company is protected.

Description

Tank wagon is antitheft, leakproof method for supervising and supervisory system

Technical field

The present invention relates to a kind of method for supervising and supervisory system that is used for tank wagon in antitheft, the leakproof of transportation.Especially; a kind of tank wagon that is used for is when transporting oil products or chemicals; can be by gathering data such as tank wagon pressure, temperature; in time find oil product or chemical spill or stolen in the mode of record analysis and remote alarms, thereby effectively protect the interests of the not contaminated and owner of cargo company of atmospheric environment.

Background technology

At present, tank wagon often takes place to leak or the stolen imagination in the way from the origin to the destination, causes very big loss to the owner of cargo, has also caused pollution to large natural environment.In order to stop the generation of this type of incident, tank wagon has been adorned leakproof, antitheft equipment mostly.This kind equipment mainly contains watch-dogs such as electronic lead sealing, liquid level instrument.The advantage of electronic lead sealing is to utilize satellite communication can realize the target real-time and precise is monitored, shortcoming is if the oil-out by the electronic lead sealing monitoring not during stolen, then can't monitor the stolen behavior, because the design reasons electronic lead sealing also can't monitor the leakage of oil situation, and the system cost height, maintenance and repair complexity (as shown in Figure 1).The advantage of liquid level instrument is accurately to monitor the variation of oil mass under quiescent conditions, shortcoming be can not be under dynamic complex road condition as: climb and fall, the road surface of jolting accurately monitor the variation (as shown in Figure 2) of oil mass.

Summary of the invention

The present invention attempts to solve the defective of leakproof as mentioned above, burglary-resisting system device, the purpose of invention provide a kind ofly be used for that tank wagon is antitheft, leakproof method for supervising and supervisory system, that the tank wagon of delivery oil product or chemicals takes place in transit is stolen, when leaking, this supervisory system can Realtime Alerts.

This method for supervising be tank wagon when transporting oil products or chemicals, can in time find oil product or chemical spill or stolen in the mode of record analysis and remote alarms by gathering data such as tank wagon pressure, temperature.This supervisory system comprises three pack modules composition: detecting module, processing module, execution module, detecting module comprise pressure transducer, temperature sensor.Processing module comprises single-chip microcomputer, registering instrument, and execution module has gsm module.Detecting module is contained on the tank wagon inner wall of oil tank top, and processing module and execution module are contained in the pilothouse.The course of work of this supervisory system is described below: the tank wagon that loads oil product or chemicals is pressed into a certain amount of inert gas (as: nitrogen or carbon dioxide) when the origin, the original pressure value is input to single-chip microcomputer through pressure transducer, the oil product temperature value is also imported single-chip microcomputer and registering instrument simultaneously, tank wagon is when starting, supervisory system is also started working, in transportation, if the liquid of tank wagon leaks, when stolen, pressure in the oil tank changes, behind the force value input single-chip microcomputer of this variation, single-chip microcomputer can be according to current temperature signal input value, after calculating judgement, confirm whether to belong to abnormal signal, if belong to abnormal signal with regard to output alarm signal, gsm module receives the report for police service and just sends short message (as shown in Figure 3) to the owner of cargo's mobile phone behind the signal.Tank wagon temperature and pressure value in the oil filling in the whole way of transportation all is recorded instrument and notes, and after tank wagon arrived the destination, the owner of cargo also can be printed the curve of temperature and pressure value, watches in the tank wagon transportation having or not abnormal conditions.

As mentioned above; the present invention's antitheft, the leakproof method for supervising and the tank wagon of supervisory system equipment have been used; when oil product or hazardous chemical leak in transit, when stolen, can the real-time informing owner of cargo, thus effectively protected the physical environment and the owner of cargo's interests.

Embodiment

Describe that tank wagon of the present invention is antitheft, before the concrete structure of leakproof supervisory system, at first describe tank wagon structure commonly used at present down: tank wagon has transport vehicle (shown in Fig. 5-1.) and storage tank (shown in Fig. 5-2.) composition, storage tank has the oil-in (shown in Fig. 5-3.) of bottom and oil-out (shown in Fig. 5-4.), the top cover at top (shown in Fig. 5-6.), vacuum pressure valve (shown in Fig. 5-7.), gauge hatch (shown in Fig. 5-5.) composition.

Pressure transducer of the present invention and temperature sensor are installed as shown in Figure 4, pressure transducer (shown in Fig. 4-1.) and temperature sensor (shown in Fig. 4-2.) are contained in tank wagon inwall top and go up the position, single-chip microcomputer (shown in Fig. 3-1.) and registering instrument (shown in Fig. 3-2.) are installed in the pilothouse, the tank wagon that loads oil product or chemicals is pressed into a certain amount of inert gas (as: nitrogen or carbon dioxide) when the origin, the original pressure value is input to single-chip microcomputer through pressure transducer, ambient temperature value is also imported single-chip microcomputer simultaneously, in transportation, oil mass can not change under the normal condition, if the liquid of tank wagon leaks, when stolen, pressure in the oil tank changes, behind the force value input single-chip microcomputer of this variation, single-chip microcomputer can be according to current temperature signal input value, after calculating judgement, if belong to abnormal signal with regard to output alarm signal, gsm module receives the report for police service and just sends short message to the owner of cargo's mobile phone behind the signal.
