Description: 毕业设计时制作的一套水位遥测自控系统,本系统以AT89S51单片机为主控单元，通过超声波传感器和液位变送器实现液位实时数据的检测和自动控制。系统分主控站与测控站，通过主控站的键盘可以实现对测控站的水位上下限的控制和显示。主控站与测控站之间的无线实时数据传输的解决方案采用广泛应用于无线抄表、工业数据采集系统和水文气象监控等领域的无线通信芯片nRF24L01组成无线高速数据收发模块。系统实现对所监控水位的短矩离无线测量与自动控制，利用GFSK实现数据高速传送以及较低的功耗。从测控站传送过来的数据通过人性化人机交换界面LCD1602实现数据的实时数据显示以及实现相应的报警提示。本系统通过单片机串口与电脑串口的通讯功能和利用互联网可以实现水位的远程测量与自动控制，这对江河水位的实时监控非常实用。本系统可能通过简单地调整就可以移植到其它物位系统与无线抄表系统，非常有研究价值。系统利用功能强大的C语言开发，并在软硬件设计中分别使用了Protel 99se 、keilC51开发平台。结果表明，该系统具有有性价比高、操作简便、可视化操作等优点.-The system main control unit MCU AT89S51 by ultrasonic liquid level sensors and liquid level transmitter implementation of real-time data detection and automatic control. System sub-master control station and the monitoring and control station, through the master control station s keyboard can be achieved on the water level monitoring station on the lower limit of the control and display. Master control station and the monitoring and control station in real time between the wireless data transmission solutions are widely used for wireless meter reading, industrial data acquisition systems and hydro-meteorological monitoring in areas such as wireless communications chip component nRF24L01 wireless high-speed data transceiver module. System monitoring the water level on the implementation of the short moments away from the wireless measurement and automatic control, the use of GFSK achieve high-speed data transmission and lower power consumption. From the monitoring station to send back

Description: 功能简介：
1 住户管理 住户基本数据管理，缴费状态查询，数据结转。
2 单价设置 分区设置水电单价，也可以单独设置
3 费用查询 只需输入本月抄表数，自动与上月相减计算出本月应缴额。
4费用查询、统计及单据显示 可进行单月收取和双月收取得查询及收费单据显示：编号、年份、月份自由组合查询。查询前应进行数据排序。
5 可根据实际需要，对该系统进行修改。
提示：
1 需求分析
实现住户等级
功能，要提供结构体得输入操作；实现统计功能，要提供相应得统计操作；；实现修改功能，要提供实现查询功能，要提供查找操作修改操作；另外还要提供键盘是选择菜单以实现功能选择。
2 总体分析
整个系统应设计为住户登记模块、统计模块、查询模块、排序和修改模块。
叫“小区水电费信息管理系统”-Features:
A basic household management household data management, payment status inquiries, data carried forward.
2 hydro unit price set partition settings can also be set individually
3 month fee simply enter the number of inquiries meter automatically subtract the previous month to calculate the amount payable for the month.
4 cost of inquiries, statistics and documents display a single month can be charged and received bimonthly made inquiries and toll receipts Show: number, year, month free combination inquiries. The data should be sorted before the inquiry.
5 according to the actual needs of the system to be modified.
Tip:
A needs analysis
Achieve household level
Function was to provide a structure input operation achieve statistical functions, have to provide the appropriate statistical operations realize modify the function to provide an implementation of the inquiry, to provide lookup operations modify operations Also provided is a se

Description: 数据查询修改:
模块主要是对小区里面的资料如用户资料，水电表资料进行查询、修改。具有保存、删除、修改、打印功能。
收费管理:
主要是对本公司的水电抄表、抄表后收费、财务收费等数据进行处理。
水费抄表：[客户，表编号，表读数，用量，单价，人工分摊系数，]
收费查询：[客户，收费员，收费日期，电用量，电费，已交电费，电欠费，水用量，水费，已交水费，水欠费，合计费用.]
交费通知单:[交费的或者没交费的通知单打印,可以全部客户打印，个人，自定义三种打印]
系统维护:
主要有数据备份、恢复等功能，是为了保持系统的正常运行。
1.清除历史数据
2.增加、修改操作员,修改密码
3.用户权限设定
4.选择某一个操作员，将相应的显示此用户所具有的权限，打上钩说明可以用，否则不可用。“全部”将权限全部选择上。选择一个操作员后，把所要分配给此操作员的权限钩上即可。
5.更换用户-Data query modification: the cell module is inside information, such as user data, water table data query modifications. With a save, delete, modify, print function. Management fees: mainly on the company' s hydro meter after meter charges, finance charges and other data processing. Water meter: [customer table number, meter reading, consumption, price, labor allocation coefficient] fees query: [customers, toll charges date, electricity consumption, electricity, have to pay electricity bills, electricity arrears, water consumption , water, had to pay water charges, water arrears, the total cost] payment notice: [notice pay or not pay for printing, you can print all the customers, personal, custom three print] System Maintenance : There are data backup, recovery and other functions, in order to maintain the normal operation of the system. 1. Clear 2. Increased historical data, change the operator, user permissions are set to change the password 3. 4. Choose one operator, the correspo
