一、系统功能
1， 本系统采用单片机技术结合收钞机实行自动收费与硬币壹元找另。
（收钞机有纸币5-50元，硬币壹元）
2， 采用五英寸液晶显示和按键进行人机对话
3， 外壳采用立柜式，即有防水结构
4， 外围电路控制64个车位锁分别工作
5， 系统最多可控制32个车位锁工作，分别进行计费，计费方式以时长为单位 （分别为30分、1小时，2小时、3小时以上按每小时计费，１０－２４小时按天结算五钟计费单位）五，种计费单位和费率机外可以修改，不到计费单位按计费单位计费。
6， 本系统控制64个车位锁，64个车位锁进行编号1-64号 系统在液晶显示器上显示64个车位锁的计费和没计费状态，（T64个车位锁状态可减少在机外可修改）。用户用按键输入，查询信息和交钱。
7，系统和收钞机有识别****的功能并退还****。
8，系统有详细记录信息
9，系统有自动生成日、旬、月、年报
10、系统设有串行口或ＵＳＢ接口可输入输出信息。
11、系统设网络接口进行远程维护
二、系统功能分析
1、系统对32个车位锁各自分开实行自动计费，汽车开进车位后，等待五分钟 （五分钟时长机外可修改）后系统开始进行计费（计费时间按车开进来时为起始时间）到用户用手指触摸，或用按键输入他的编号，系统显示该编号的计费金额，显示时为终止时间交钱，用户交了钱后系统马上将车位锁开锁。系统就结费保持原状。
2、如果汽车开进车位后，等待五分钟 （五分钟时长机外可修改）内汽开走了系统就不计费，保持原状。
3、客户向系统交了钱，客户车不开走系统等待10分钟后将原来的计费延续下来，在已交的钱用完后再将车锁住，等待客户下次来交钱，第二次交钱后客户车又不开走，系统等待10分钟后将原来的计费延续下来，再将车锁住，在已交的钱用完后再将车锁住，第三次交钱后客户车又不开走，系统等待10分钟后将原来的计费延续下来，再将车锁住，在已交的钱用完后再将车锁住，以上类推最后结费将总交的钱合计，时长合计，根据计费标准结费。
The A SY-1228 car lock automatically charges system
A, system function
1, this system adoption list the slice machine technique combine to accept the Chao machine execution auto charge and coin 1 dollars seek another.
(Accept Chao machine to have the banknotes 5-50 dollars, coin 1 dollars)
2, adopt five inch LCDs to show to carry on person's machine to have a conversation with key
3, the outer shell adoption signs a cabinet type, then have waterproof structure
4, the outer circle electric circuit controls 64 cars lock to work respectively
5, the system at most can control 32 cars lock work, carry on a charge respectively, charge a way with long is unit(distinguish to 30 for cents and an hour, 2 hour, for more than 3 hours press the per hour charge, settle accounts five clocks charge unit by the sky for 10-24 hours) five, growing to charge unit and fee rate machine outside can modify, not arrive charge unit press charge unit charge.
6, this system controls 64 cars lock, 64 car locks carry on the serial number No.1-64 the system show 64 cars on the liquid crystal display the charge of the lock and don't charge status, .(the T64 car lock status can reduce outside the machine can modify)The customer uses a keystroke, search information and hand over money.
7, system and accept Chao machine have already identified****Of the function combine to send back****.
8, the system has a detailed record information
9, the system has automatically born day, a period of 10 days, month and annual report
10, the system establish in a string of line or ＵＳＢ to connect to input an exportation information.
11, the system establish a network to connect to carry on a long range maintenance
Two, the system function is analytical
1, the system respectively and separately practice an automatic charge to the 32 cars lock, the car after opening into the car waits for after five minutes(five minutes leader plane the outside can modify) system starting carrying on a charge(account to take a lot of time to press the car to open to come in for start time) to arrive a customer to by hand point a touch, or using keystroke his serial number, system shows the charge amount of money of the serial number, show in order to terminate time to hand over money, the customer handed over after money system right away car the lock opens a lock.The system knots a fee to keep original shape.
2, if the car after opening into the car waits for a vapor driving away system not to charge and keeping original shape in five minutes(five minutes leader plane the outside can modify).
3, the customer handed over money to the system, customer's car not drive away system wait for continuing an original charge down after 10 minutes, after money having been already handed over is used up lock a car again, wait for customer handing over money next time, for the second time hand over after money customer's car again not drive away, the system waits for continuing an original charge down after 10 minutes, again lock a car, after money having been already handed over is used up again lock a car, for the third time hand over after money customer's car again not drive away, the system waits for continue an original charge down after 10 minutes, again lock a car, after money having been already handed over is used up again lock a car, above type push the end knot fee will always hand over of aggregate money, long add up, according to charge standard knot fee.
