Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to an electronic seal and a remote monitoring method,

The present invention relates to an electronic seal and remote monitoring method and apparatus for a lubrication apparatus capable of monitoring whether a lubrication apparatus operated by software is sealed electronically and whether the lubrication apparatus is arbitrarily operated on a site or a remote site.

In general, lubricators that are supplied to the domestic market are strictly managed and operated as legitimate lubricators according to the 'Law on Weighing' in order to establish a fair trading base.

The recently released gas lubrication apparatus is an electronic metering apparatus, and the software of the lubrication apparatus processing the raw data is very important factor for determining the quantity and performance of the lubrication apparatus.

In accordance with this trend, the International Organization of Legal Metrology (OIML) has adopted the 'General requirements for software-controlled meters (OIML D 31: 2008)' as a reference standard.

On the other hand, in the case of a gas pump capable of illegal operation, the program or the circuit is manipulated so as to be less than a certain amount in some workplace. In other words, at some workplaces, the flow rate is tricked and sold to consumers based on program manipulation or circuit change of the lubricator.

For example, pulse amplifier and remote control, encoder modulation, and software modulation in the main board can be distinguished.

First, in case of the pulse amplifier and the remote controller, a modulator is installed on the line between the pulse generator and the main board, and the pulse transmitted from the pulse generator to the main board is modulated. The pulse generator is remotely controlled using a wired or wireless remote controller This is the case.

In the case of encoder modulation, a method of replacing an encoder provided in a pulse generator with an encoder that is modulated similar to a normal component so as to feed less than an actual amount of gasoline, is a method in which the power of the lubricator is turned on / off, .

Further, in the case of software modulation in the main board, as a method of modulating the operation by removing the program of the main board, downloading the modulated program, and adding a variable (K-factor) (Preset device).

However, the above-described conventional operation examples of the lubricators and the like are not getting smaller and are becoming more and more advanced, and various methods are used to prevent this, but it is still necessary to precisely detect the operation of the lubricator, There is no solution available.

In addition, in the conventional lubricators, since the structure of the lubricator is digitized due to the development of information communication, and the application of the network interlocking technology is increasing, there is a concern that the operation program is manipulated. , There are no processors and applications that are supported for security, and there is a problem that security is largely lacking.
