Field calculation, reading and writing system and method for rail freight metering and safety information

Abstract

The invention relates to a field calculation, reading and writing system and method for rail freight metering and safety information. The system is composed of an electronic tag, a data management platform and a handheld mobile reading-writing device. The handheld mobile reading-writing device consists of a verification module, a metering module, a transmission module and a calculation module. An electronic product code zone and a user zone inside the electronic tag carries out sharing; and the electronic tag is used for storing railway tanker information, cargo information and monitoring results. The handheld mobile reading-writing device is used for capturing the electronic tag, obtaining an electronic tag identifier and railway tanker information stored into the electronic tag, metering, verifying, and calculating the railway tanker information, and then writing cargo information and a monitoring result that are obtained by analyzing the railway tanker information into the electronic tag. The data management platform in communication connection with the transmission module is used for storing the monitoring result, the railway tanker information stored into the electronic tag and data after electronic tag identifier binding. Therefore, security application of rail freight metering on complex work conditions especially an explosion-proof environment can be realized.

Description

technical field [0001] The invention relates to the field of railway freight safety measurement, in particular to a system and method for on-site calculation and reading of railway freight measurement safety information. Background technique [0002] At present, as the railway develops towards the direction of modern logistics, its railway cargo transportation, measurement, safety, management and other related technologies have also been developed rapidly, especially the measurement safety information of liquid dangerous goods is very important. In my country, 90% of liquid dangerous goods are transported by railways, and 90% of railway dangerous goods are transported by railway tank cars. There are more than 120,000 railway tank cars in my country, accounting for about 15% of the total railway freight cars. They are the main means of transportation for bulk liquid goods such as petroleum, chemical products, and vegetable oils, and they are also capacity measuring instrument...

AI Technical Summary

Problems solved by technology

[0004] At present, when national petroleum, chemical and other railway tank car user companies obtain the above information, they need to manually check and record the volume table information, and manually enter the computer software to calculate the weight of the loaded product. Due to too many intermediate links, it is easy to cause the volume table number and other marks to be smeared. Making mistakes and obtaining wrong information will eventually lead to inaccurate trade settlement, affect corporate profits, and cause trade disputes

On the other hand, railway tank car user enterprises and railway transportation enterprises use manual inspection of verification certificates and related materials, and on-site verification to determine and control the loading capacity and information related to the transportation of dangerous goods. This method has high manual dependence, many error links, and Disadvantages such as low work efficiency and affecting transportation and production
