Intelligent filled gas cylinder detection system and method

Abstract

The invention discloses an intelligent filled gas cylinder detection system and method. The system comprises an image acquisition unit, an image recognition unit, a filling weighing position, a to-be-filled gas cylinder and a processing unit. The image acquisition unit is used for acquiring an image of a working area of the filling weighing position, and the image recognition unit is used for recognizing a working time point when the to-be-filled gas cylinder is filled at the filling weighing position according to the image of the working area of the filling weighing position. The processing unit is used for identifying and judging the consistency between the working time point when the to-be-filled gas cylinder is filled at the working area of the filling weighing position and the gas cylinder filling record time point uploaded by the weighing position, and if the working time point when the to-be-filled gas cylinder is filled at the working area of the filling weighing position is identified and judged to be inconsistent with the gas cylinder filling record time point uploaded by the weighing position, it is determined to be illegal filling. According to the technical scheme, theworking time point is obtained by identifying the image of the working area, so that other gas cylinders are prevented from being filled at the filling weighing position by using a non-working time point, and the technical problem of monitoring illegal filling is solved.

Description

technical field [0001] The invention relates to the technical field of intelligent monitoring and management of gas cylinder filling, in particular to an intelligent monitoring and management method for illegal filling behaviors at filling stations of gas cylinders (including liquefied petroleum gas cylinders, industrial gas cylinders, and vehicle-mounted gas cylinders). Background technique [0002] At present, the operators of gas cylinder filling units illegally fill non-company-owned property cylinders or illegal gas cylinders for personal gain. The lack of security inspection of gas cylinders and their use environment leads to leakage and deflagration accidents of illegally filled gas cylinders. , A direct threat to the safety of the public's personal and property. [0003] As we all know, the current policy documents of the gas cylinder supervision department (the State Administration for Market Regulation or the local market supervision bureau) require the filling sca...

[0002] At present, the operators of gas cylinder filling units illegally fill non-company-owned property cylinders or illegal gas cylinders for personal gain. The lack of security inspection of gas cylinders and their use environment leads to leakage and deflagration accidents of illegally filled gas cylinders. , a direct threat to the safety of the public's personal and property

[0003] As we all know, the current policy documents of the gas cylinder supervision department (the State Administration for Market Regulation or the local market supervision bureau) require the filling scales of the gas cylinder filling enterprises to implement "interlock filling" control (that is, the filling unit implements "interlock filling" control). "Controlled filling scales can only fill qualified self-owned property bottles technically, and cannot fill unqualified gas cylinders or non-self-owned property right bottles). When filling gas cylinders, the filling unit must, in principle, communicate with the local After the qualified gas cylinder file data in the gas cylinder safety supervision system (hereinafter referred to as the supervision system) of the supervision department is compared successfully, the gas cylinder filling record is uploaded in real time; The gas cylinder file data of the filling scale system is remotely controlled and the gas cylinder filling record is uploaded, but because the filling system of the filling unit’s filling scale is deployed on the computer of the filling unit, based on the current enterprise filling scale equipment hardware There are deficiencies or defects in management and control, and the actual situation of "subjective illegal operation" of the enterprise. The filling unit can artificially "unlock the filling" and modify the local filling system by artificially unplugging the battery on the filling scale or closing the solenoid valve. "technical back door" and other violations, evade the supervision of "interlock filling", make the filling scale work in a single machine mechanically, separate from the verification data of the gas cylinder file in the filling system, and fill any "gas cylinders uncontrollably". "Cylinders", including non-free property rights cylinders or illegal gas cylinders that have not been inspected within the time limit, will not upload gas cylinder filling records to the supervision system; thus, from the current technical level, the supervision system will not "unlock and fill" artificially. The filling scales that violate the regulations are out of control, and there is a lack of corresponding monitoring methods. It is impossible to prevent the filling units from filling non-company-owned property cylinders or illegal gas cylinders in violation of regulations. The foundation of cylinder safety traceability brings hidden dangers of gas cylinder safety to the public
