brief introduction
Install a non-contact IC card machine linkage controller on the tanker, which can realize data communication with the tanker, and link the tanker card-machine linkage controllers to a network through the RS485 bus (or other data bus) , Through the gas station data concentrator to connect with the management computer placed in the gas station business room. Install IC card card machine linkage tanker information management system software on the management computer. The radio frequency IC card card machine linkage controller can complete various data communication functions with the tanker, and can control the refueling process of the entire tanker to realize the linkage of “card” and “machine”.
Contactless IC card, also known as radio frequency card, is a new technology developed in the world in recent years. The data in the card can be read and written when the card is close to the surface of the reader. It successfully integrates radio frequency identification technology. Combined with IC technology, it solves the problem of passive (no power in the card) and contact-free. It is a breakthrough in the field of electronic devices. Compared with contact IC cards, non-contact IC cards have the following advantages:
High reliability There is no mechanical contact between the non-contact IC card and the reader, avoiding various failures due to contact reading and writing. For example: failure due to rough card insertion, non-card foreign object insertion, poor contact caused by dust or oil stains, etc. In addition, there is no exposed chip on the surface of the non-contact IC card, so there is no need to worry about chip falling off, electrostatic breakdown, bending, damage, etc., which not only facilitates the printing of the card, but also improves the reliability of the card.
Convenient and fast operation. Due to the use of radio frequency communication technology, the reader can read and write the card within 10cm, without the action of inserting or removing the card. The non-contact IC card has no directionality when it is used. The card can be swept across the surface of the reader in any direction, and the reading and writing time is no more than 0.1 seconds, which greatly improves the speed of each use.
Security and anti-conflict The serial number of the non-contact IC card is unique. The manufacturer has solidified this serial number before the product leaves the factory and cannot be changed. No two cards in the world have the same serial number. A two-way verification mechanism is adopted between non-contact IC card readers, that is, the reader verifies the legitimacy of the IC card, and the IC card also verifies the legitimacy of the reader. The non-contact IC card must be mutually authenticated with the reader three times before operation, and all data is encrypted during the communication process. Each sector in the card has its own operating password and access conditions.
The radio frequency IC card machine linkage tanker information management system is equipped with a radio frequency IC card machine linkage controller on each tanker. Each refueling can be completed with a card, and the fixed customer or internal oil can be directly used for transactions with the issued card, which can realize the integrated high-level management of people-vehicle-oil. For mobile customers, fueling personnel can use their employee cards to complete transactions, making the employee management and assessment system more complete. This system is particularly suitable for the management of petroleum retailers and internal gas stations of enterprises and institutions with high management requirements.
The main modules and functions of this system: real-time monitoring, data query, report generation, parameter setting, oil product restriction, identification, card machine linkage, permission setting, offline refueling, receipt printing, invoice printing, data backup, vehicle verification, On-site recharge, customer information registration, recharge information management, report summary, receipt printing, etc.
