Explosion-proof built-in IC (Integrated Circuit) card batch control instrument system

Abstract

The invention discloses an explosion-proof built-in IC (Integrated Circuit) card batch control instrument system, applicable to loading management systems for loading process control and informatization construction in a petrochemical refinery, an oil depot, a dangerous cargo warehouse and the like. The explosion-proof built-in IC card batch control instrument system comprises a batch control instrument, an IC card reader-writer and a server side, wherein the server side stores loading information into a database, and encrypts and writes the loading information in an IC card; the batch control instrument comprises an anti-collision module, a cryptographic check module, a PLC (Programmable Logic Controller) register and a batch control instrument built-in IC card reader-writer; the IC card in which the loading information is written is in radio-frequency communication with the batch control instrument built-in IC card reader-writer; the batch control instrument starts the anti-collision module and performs cryptographic check on the loading information in the IC card; the loading information in the IC card is stored in the PLC register of the batch control instrument; the batch control instrument built-in IC card reader-writer changes the loading information in the IC card to a loading state; and after loading is completed, the batch control instrument built-in IC card reader-writer changes the loading information in the IC card to a loading-completed state.

Description

technical field [0001] The invention relates to a loading management system used for loading process control and information construction of petrochemical refineries, oil depots, dangerous goods warehouses, etc., in particular to an explosion-proof built-in IC card batch controller system. Background technique [0002] At present, in the process control of tank truck loading in chemical tank farms, the loading batch controller and IC card reader are used independently, and communication between the two cannot be realized. When loading, the operator first reads the IC card The card reader swipes the card, and the content in the card is transmitted to the computer in the control room through RS485. The operator in the control room recognizes the content of the card by operating the computer software, and then sends instructions to the loading batch controller through the computer software. The vehicle batch controller only allows the vehicle to be loaded after seeing the recei...

[0002] At present, in the process control of tank truck loading in chemical tank farms, the loading batch controller and IC card reader are used independently, and communication between the two cannot be realized. When loading, the operator first reads the IC card The card reader swipes the card, and the content in the card is transmitted to the computer in the control room through RS485. The operator in the control room recognizes the content of the card by operating the computer software, and then sends instructions to the loading batch controller through the computer software. The vehicle batch controller only allows the vehicle to be loaded after seeing the received instructions. In this loading mode, the on-site operator cannot timely display whether the card is successfully swiped after swiping the card. The loading efficiency is low and the operation is troublesome. In addition, each set of IC card read The card reader needs to put cables to the control room. If there are multiple sets of car cranes, multiple sets of IC card readers are needed, and a lot of communication cables need to be placed on the control computer, which adds a lot of cost to the entire system.
