The system develops the plain chart to explain that,
Gas station: Is the Chinese petrification refined oil retail sales service occurrence place, directly faces the customer to provide refuels the service.
Sends the card mesh point: Provides opens a bank account, to send the card, the sufficient value, the circle for the user saves, reports a loss, service and so on inquiry.
Level pretage system: Is sending the card mesh point and the gas station and the provincial level data central provides the data to retransmit the function.
Provincial level data central: The establishment user account, carries on refuels the card transaction clear minute, criticizes, is the business management and the data processing core.
China petrifies the total center: Is responsible to refuels the card different transaction clear to divide and the dispute arbitration, to based on refuels the IC card transaction system retail sales service to carry on the management
Provincial level administrative center: Carries on the management to the provincial level petroleum company respective gas station retail sales service.
Level administrative center: (City) the level petroleum company respective gas station retail sales service carries on the management to the place.
County level management terminal: Carries on the management to the county level petroleum company respective gas station retail sales service.

2. Center petrifies to the tube controls the PC hardware the request

Entire will refuel in the IC card project 25,000 gas stations all to dispose a steady pipe to control PC to do for the service terminal. The tube controls PC to be responsible for the quantity and the amount statistics which the daily IC card refuels, the transaction bill printing, the accelerator monitoring, will sell the transaction to send out the province data central every day, and will download the national IC card user the account management information and the most fresh oil price and so on. Below is the tube controls the PC function schematic drawing:

The gas station tube controls PC to play the count for much role, once the tube controls PC to break down, the gas station normally transports about to comes under the influence. China petrifies 25,000 gas stations distributions quite are dispersible, the majority of gas stations are far away the town center, very many service stations are located the mountainous area, once the tube controls PC to break down, the service replacement can extremely trouble. Therefore, China petrifies to the tube controls PC the most important request is the system reliability. Next, the accelerator controls PC through the string mouth and the tube connected, the gas station accelerator number is different from 2 to 30, therefore requests the tube to control PC to have the stronger function extension. In order to guarantee the tube controlled the PC system the stable movement, China petrifies selects Turbolinux Data Server to do for the tube controls PC the operating system, therefore requested the tube to control PC to be completely compatible on the hardware with Turbolinux, and could smoothly move.
Controls at the beginning of the PC equipment shaping in the tube, altogether has 10 commercial PC and the industry PC factory participation shaping. After in every way comparison, center petrifies finally controls the tube PC to decide as industry PC. Industry PC was enhancing the system reliable aspect to make many special designs, its reliability greatly surpassed commercial PC. Under is the commercial PC system structure drawing:

This kind of structure we called it the big motherboard structure, this kind of structure extremely does not suit the field use and maintains the request. On the motherboard integrated the north and south bridge control chip and so on the active device. The active device compares to the electric capacity resistance and so on the passive component is easy to damage. Once the female board damage, carries on the replacement to be able extremely to trouble: After the on-site maintenance personnel first needs to capture on the motherboard all data lines, needs to draw out inserts on the motherboard all periphery card, the criss-crossed card, reveals the card and so on, finally needs to fix the motherboard the bolt 11 to download, can dismantle the motherboard. Exchanges a new motherboard also to take 11 repetitions above processes. Like this replaces a damage the motherboard, needs to spend 30 minutes time. Such long MTBF (average breakdown maintenance time) is does not permit regarding the gas station actual use. Moreover, commercial PC quakeproof has not made the special design to the system, has the vibration disturbance in periphery the situation, is very easy the breakdown which appears the hard disk damage and the card jumps out. The hard disk once damages, a day-long transaction data completely will lose.
Was opposite to commercial PC, industry PC has made the very big improvement in the structure, below was the industry PC structure schematic drawing:

The industry PC motherboard makes inserts the card the form, inserts in the passive ledger wall (passive backplane) on. On the passive ledger wall only has ISA, the PCI main line meets the plug-in unit as well as the electric capacity resistance and so on the passive component, therefore the passive ledger wall damages the probability is extremely low, usually does not have sorrow of the replacement. If the motherboard damage, only needs the motherboard to draw out then. Therefore the system MTBF time greatly reduces. In addition the system motherboard and the periphery card have special is fixed 压条, prevented the board card jumps out. The hard disk driver has the hard disk to evade inspires and the absorption of shock rubber packing, can reduce the vibration to the hard disk damage. In order to enable industry PC reliably to work under the high dust environment, enters the gusty area in industry PC front, has 可更�?dust screen. The following chart shows:
