Now illustrate the course of work of this parking recording display (1) with the process flow diagram of Figure 11:

The single-chip microcomputer of serving as control circuit (11) is behind power connection, by external RC circuit reset.After detection has IC-card (3), relatively the storage volume of IC-card (3) whether＞minimum value? if not glittering and hummer (19) sound of LED (18) if pointed out enough 10 seconds or pressed and wake up and cancel key (12c), is then shut down, and is entered park mode.If the storage volume is＞minimum value; the storage amount of money that then shows IC-card (3); detect again the numeral input arranged on the keyboard? do not have; then check options button (12b) input arranged? no, check that then coloured rate plate (13) is dug? no, then get back to detect and check on the keyboard that the numeral input is arranged? so circulation; all there is not input; circulate after 60 seconds, shut down dormancy, get back to and wait for that keyboard wakes up and cancel key (12c) input wakes up.

As waking up and cancel key (12c) when input, the storage volume that flow process enters IC-card (3) whether＞minimum value? if not, equally handle with above-mentioned.If then detecting has the numeral input on the keyboard? if have, then the numeral of this input is stored and demonstration as the car item.

Check the button input that stores remaining sum in the demonstration IC-card (3) that whether has in the options button (12b); Whether requirement shows the button input of last time from the amount of money of IC-card (3) deduction; Require the park button input of institute's time-consuming of last time? if have, then show selected data.Check the button input that the ground area code in the options button (12b) is arranged then? does then checking have rate to select input if do not have?

If the button input of the requirement demonstration ground area code in the options button (12b) is arranged, flow process enters the sub-process of checking and can rewrite the ground area code.After showing the ground area code, whether reach 60 seconds through checking circulation, whether examination wakes up and cancel key (12c) input, if having, then cancels the ground area code of original or firm input.Whether examination has the button input again of selecting to show the ground area code again, if having, flow process is walked out sub-process.Does then detecting have the numeral input if do not have on the keyboard? if have, then all be regarded as ground area code input and be stored and show.If do not have, then still get back to demonstration ground area code.This sub-process allows the driver check and rewrites the ground area code.Checking wherein whether circulation reaches 60 seconds, is that both no longer operations are not pressed again when selecting to show the button of ground area code again for after allowing the driver check or having rewritten the ground area code, fullly walks out sub-process automatically after 60 seconds.

Does flow process enter inspection and has or not rate to select? if do not have, then check through this step, whether circular wait 60 seconds? if mistake not also, then whether examination wakes up and cancel key (12c) input, if have, the then car item numeral imported of front, or the car item that was stored originally is cancelled, and getting back to detect to have on the keyboard does not have the numeral input.Can see that have 2 places on the process flow diagram and detect to have on the keyboard and do not have the numeral input, the numeral input in the sub-process is to change and input ground area code, the outer numeral input of sub-process be for a change with input car item.

After the inspection, if coloured rate plate (13) is dug, then for there being rate to select input, corresponding rate LED is bright.Is inspection support (1b) opened? if be opened, then enter accounting routine.If be not opened, still get back to then and checked whether circular wait 60 seconds? if spent 60 seconds, support (1b) is not opened yet, just is used as the driver and just checks data, auto stop.

If described support (1b) is opened, then enter accounting routine.Showing the car item in turn, does the ground area code from 5 minutes amount of money of IC-card (3) button, check whether the amount of money was enough deducted 5 minutes by rate? if not enough, then shut down, enter park mode.If the amount of money enough deducted 5 minutes, whether reach 5 minutes after then checking amount deducted? if full 5 minutes, then get back to by 5 minutes amount of money of rate button.If less than 5 minutes, check that then support (1b) is closed? if do not close, continue to check and whether reach 5 minutes.If support (1b) closed, then stop to charge, the car item that this time berthed, rate, amount deducted, the time on date deposits in the IC-card (3) the correspondingly store files of area code (RF) lining in, shows that IC-card stores remaining sum 30 seconds, shuts down then, enters park mode.

Driver's operating process is: before leaving car, click waking up and cancel key (12c) of parking recording display (1), display (1) promptly shows the storage amount of money of IC-card (3).According to the ground colour code input in parking stall car item, dig coloured rate plate (13), open support (1b), display (1) is placed on automobile front glass window inwall, and display (1) begins to charge.Before the driver drove to leave the parking stall, (1b) closed support, stopped to charge.

After waking up, it is preceding to open support (1b), and the driver can import the car item by numerical key, can press cancel key (12c) cancellation, presses numerical key input car item more again.

3 keys that the driver can press respectively in the options button (12b) are checked storage remaining sum in the IC-card (3); Last time is from the amount of money of IC-card (3) deduction; The institute's time-consuming of parking last time.Can press the button that shows the ground area code and check the ground area code that has stored.Check in the ground area code process, can press cancel key (12c) cancellation, press numerical key input ground area code more again.As previously mentioned, at areal, need not to park at every turn and all will import the ground area code, only need enter this area, input gets final product when using for the first time.If glittering and hummer (19) sound of LED (18) is arranged, illustrate that the interior amount of money of IC-card (3) is not enough, need supplement with money near the agency that supplements with money.

The batch valency of the IC-card socket (16) in the parking recording display of present embodiment (1) is several yuans, and just than single interface IC card expensive several yuans of the costs of double-interface IC card, the active wireless transmitting-receiving equipments of a cover is much lower more than also increasing, no matter this active radio transceiver is to adopt radio, infrared still microwave.The price of described non-contact reader-writer is 400～800 yuans, thereby adopts the cost of the vehicle parking charge system of the utility model Data acquisition, supervision facility, and is lower than upright charge time set and other vehicle-mounted charge time set.The cost of parking recording display can be collected to the car owner with lower down payment form, is convenient to promote.
