1. System Overview
This rice selling system uses the radio frequency function of the ID card to store the recharge amount in the system through a read-write device. When consuming, set the consumption amount on the charging device, and put the ID card close to the induction loop of the card reader, and the charging machine will transmit the corresponding consumption amount of the ID card to the system for deduction, thereby completing the consumption process. It has the characteristics of simple, fast, clean and sanitary to avoid the possibility of pollution and human error; this rice selling system has a password protection function to ensure that the card of the outside unit cannot be consumed in the unit to avoid losses; it can realize ordinary charges, fixed value, and A variety of charging methods such as counting, accounting, counting + charging, fixed value, etc., and can set the maximum consumption amount according to needs, or implement limit and limit consumption; the system can use both real-time and non-real-time methods (when real-time network fails Can be manually set to switch to non-real-time accounting), the machine and database are redundantly backed up to ensure that data is not lost; the system can complete various functions such as card issuance, recharge, consumption, subsidies, card refund, statistics, query, and loss reporting. Provide a variety of simple operation, complete functions of the report; the rice selling system at the same time random consumption and fixed-value consumption two consumption modes can be set and switched through the machine keyboard, convenient and fast, can meet the different requirements of different consumption modes at different times; this system group The network adopts the traditional RS485 network, and the local area network communication can also be realized through the TCP/IP-485 converter. This system supports both ACCESS and SQL databases; the recharge operation of this system for ID card can be recharged on the computer through the card issuer, or an additional recharge machine can be configured for recharge.
2. System composition
This system is composed of the following equipment: computer or server, RS485 converter (or TCP/IP-485 converter), card issuer, charging machine, recharge machine. The system network is as follows:
instruction
This system is an ID consumption model (that is, the amount is not stored in the card, but in the database).
The consumer machine is required to be an ID consumer machine.
IC card or ID card can be used, but only one of them can be used, and the two cannot be used at the same time.
The card must be equipped with equipment to use, with IC card equipped with IC card reading equipment, and ID card equipped with ID card reading equipment.
The optional equipment is as follows:
install equipment
The system design scheme follows the principles of the most advanced technology, high-quality equipment, optimal cost performance, and the equipment used for 10 years without lagging behind. In order to achieve the purpose of simple and quick construction, avoiding repeated wiring, saving costs, and easy system expansion in the future, it is in the networking scheme On the one hand, we suggest adopting the Ethernet/RS485 networking solution. The system network structure is divided into two layers. The upper layer is an enterprise LAN based on the TCP/IP protocol, that is, the system topology is a first-level subnet (Ethernet). The lower layer is a bus control network based on the RS485 communication protocol.
1. For 485 communication, a shielded twisted-pair network cable (usually 8-core) must be used, and the shielding layer must be connected to the ground (GND) of the converter.
2. Do not share the trunking with other strong wires for communication lines. Avoid fluorescent lamps (because there are ballasts in fluorescent lamps, electromagnetic interference will occur).
Precautions:
The 8-core communication cable uses only two of the cores, and the other 6-cores should not be short-circuited with each other. They must be wrapped separately, otherwise, the charging opportunity will display “123456” and cannot be used normally.
