Problems solved by technology

However, with the continuous increase in the use of gas cylinders and the drive of interests, the safety of gas cylinders has become the most important problem to be solved in this field.
[0005] At present, there are many safety hazards in the actual use of CNG gas cylinders in China, mainly in the three major links of installation, filling and use: for example, some people without professional skills use simple facilities to carry out CNG gas cylinders under the drive of interests. Illegal modification, which is far below the requirements of the corresponding safety technical specifications for the installation of CNG gas cylinders; during the filling process of CNG gas cylinders, due to the lack of feasible testing measures, there are also cases where the gas filling stations do not review the safety performance of the gas cylinders Just add gas directly or continue to add gas knowing that there are safety problems, so that some gas cylinders with expired inspections or substandard safety performance are still in use; at the same time, the serial number, production date and inspection time during use of CNG gas cylinders Such data are very important information. The gas station should check these data before each refueling. Vehicles with unqualified gas cylinders will not be refueled. The management department also needs to update the data in real time to keep abreast of the gas cylinders. The specific use of the specific use, in order to clean out unqualified gas cylinders at any time, reduce the hidden dangers of installation
[0006] In order to deal with the above problems, there are currently some technical measures for the supervision of vehicle gas cylinders, but the effect is not ideal, such as "network + remote database mode", which follows the current mainstream control method "embedded + communication", through the field terminal The ID number of the device identification tag is integrated by means of communication to the remote database for comparison, and then the value is returned. At the same time, the system is manually unlocked in the offline state, and then local operations are performed through manual intervention. The technology is mature and stable, and the local computing environment is simple. Deployment is easy; but this technical solution is not compatible with gas dispensers; if full data monitoring (gas filling records, quantity, time, gun number) is required, manufacturers must be required to provide private protocol docking, gas dispenser manufacturers are out of their own knowledge For the protection of property rights, it is difficult to provide in-depth data interfaces, and management loopholes are relatively large; at the same time, system manufacturers in various cities are not unique, and monitoring data is inconsistent. In a multi-system environment, data integration and business docking are very difficult and consume a lot of manpower and material resources; and The operation and maintenance of the basic network and on-site equipment is very difficult. Under the existing technical framework, the provincial bureau cannot guarantee that the gas filling station will not stop production due to the provincial bureau system, network environment, and monitoring equipment, and does not have the ability to resist counterfeiting labels, etc.
[0007] Another technical solution is to adopt the method of "distributed data + incremental synchronization + online comparison". From the perspective of current supervision, this solution has the lowest risk in theory; it can effectively solve the problem of offline verification; but it carries distributed databases for computing The environmental requirements are high, and embedded systems are not recommended to carry high-volume tasks. If X86 or other RISC environments are used to support database operation, the on-site power consumption will exceed 100 watts. After the equipment is explosion-proof, fan heat is a problem, and additional CAN expansion is required. Or 485 and other communication interfaces to solve the legalization problem. At the same time, the availability of embedded databases, equipment operating systems, and peripheral infrastructure (power, network) cannot be guaranteed; for vehicles in other provinces, the ability to deal with emergency refueling events is weak (the database does not include this part of the information) and cannot resist copying labels, cloning labels and exposing regulatory loopholes, etc.

Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0038] In order to effectively solve many deficiencies in the field of existing vehicle gas cylinder supervision, the present invention makes technical improvements from the following multiple angles, so as to realize efficient dynamic monitoring of vehicle gas cylinders, specifically including:

[0039] 1. Signature verification process: Before refilling or filling the vehicle gas cylinders, each gas dispenser at the gas filling station needs to use the handheld terminal of the gas filling station to scan the electronic label on the vehicle gas cylinder, and check the label itself. The legality and validity of the content contained in the label are verified, and the verification methods can include two modes: CA signature verification and local data verification. ...

Abstract

The invention discloses a vehicle gas cylinder dynamic monitoring system and a monitoring method. The system includes an electronic label for storing label plaintext information and anti-counterfeit signature information corresponding to the vehicle gas cylinder; The handheld terminal of the gas station and the gas filling station that controls the gas filling machine to allow gas filling or terminate the gas filling operation according to the type of the verification message received, and sends the gas filling record information to the provincial monitoring center after the gas filling operation is completed. control system. The present invention cannot provide gas refueling service when the legal electronic label is not scanned; and when the legal label is scanned, the central control system of the gas filling station also performs double verification of the authenticity of the local label and comparison of the local database. Provide gas refilling service; the invention not only ensures the speed of inspection and release and offline verification, but also solves the problem of dynamic information supervision of gas cylinder attributes during use; at the same time, it adopts the heartbeat protocol mechanism to maximize system availability.

Description

technical field [0001] The invention relates to a data monitoring technology, in particular to a dynamic monitoring system and a monitoring method for a vehicle gas cylinder. Background technique [0002] At present, gas energy (especially CNG, LPG, LNG, etc.) has become an important type of energy in the development of modern science and technology. Alternative Energy, [0003] The following is an example of compressed natural gas (CNG). CNG has quickly become an ideal alternative energy source for vehicles due to its characteristics of no pollution, high safety, and low cost, and is increasingly showing strong development potential. In view of the above advantages of CNG, compared with existing fuel vehicles, vehicles using CNG fuel have the advantages of saving fuel costs, high safety, good environmental performance, and long engine maintenance cycles, and have broad development prospects. [0004] At the same time, in view of the fact that CNG gas cylinders are special...
