Remote Prepaid Water Sales Management System
System Overview
SH-METERS wireless remote centralized meter reading system uses the latest Internet of Things technology to automatically transmit the data of water meters and other meters to the server, and operate the meters through the application side to realize remote management of meters.
This system is suitable for various environments such as factory buildings, office parks, residential buildings, commercial markets, campuses, white-collar apartments, water affairs/municipalities, hospitals, ports and docks, and is not affected by distance and on-site environment.
The remote pre-paid water sales management system is mainly aimed at merchants’ water use, and realizes the intelligent management of merchants’ water. Kerui terminal prepaid water energy meter to independently measure the water consumption of each user.
The communication management machine collects the data of all terminal internal control prepaid water meters through the RS485 bus. The communication management machine transmits the data to the remote management computer through a dedicated network or local area network composed of optical fibers. The system management software stores and processes the data to form files in the form of graphics, text, etc. required by the property management party, so as to realize the intelligent management of the water used by the merchants in the entire farm.
System Design Plan
Overall system plan
2. the characteristics of the system
2.1 Independent measurement control
The metering unit corresponding to each user unit in the water meter is independent to ensure measurement accuracy; the control unit is independent to ensure control reliability.
2.2 Data Collection
The management software automatically collects the water energy data of each user, and has the functions of single point, unit, and group collection.
2.3 Separation of communication management
The information collection of the water meter data is realized through the communication management machine embedded with the operating system, so that the information collection is implemented hierarchically, and the real-time data collection is guaranteed.
2.4 Multi-channel remote recharge
The user can recharge remotely by logging in to the recharge website using a mobile phone or bank card. If necessary, the user can also go to the property for cash recharge. The APP is compatible with both Android and Apple mobile operating systems.
2.5 Meet the prepaid requirements
Prepay for water energy, pay first and use water later, eliminating the need for manual meter reading, reminder payment and other tedious tasks. There is no need to configure an IC card. Each user has an independent account, which is convenient and easy to manage.
2.6 Remote control
It can remotely control the opening and closing of each metering unit, and remotely perform parameter setting function and user information modification and setting for each prepaid water energy meter.
2.7 SMS alarm
When the user's water bill is lower than the set alarm value, the system will send a prompt message to the user to remind the user to recharge as soon as possible.
2.8 Consolidated measurement
When a tenant needs to rent multiple stores, multiple stores can be merged through software. The user only needs to recharge one of the water meters, and only if the total remaining water is greater than 0, there will be no water cut in any way.
2.9 Users can query by themselves
Users can inquire about personal information, balance, recharge records, water usage records, etc., by logging into the mobile website.
2.10 Printing function
Can print each user's monthly energy consumption expense report and single household expense list.
2.11 Data is safe and reliable
The database adopts a high-precision database, which is stable in operation, high in security, and strong in scalability. Non-operators can not change it at will to ensure data security. It provides historical water consumption data for each user, including previous water purchase dates, water purchase records, monthly water consumption records, etc. .
System Analysis
1. system function
1.1. Reading function: Automatically read the accumulated water energy and other information of each user's water energy meter of the central device according to the set reading interval and meter reading cycle, and has the functions of real-time random reading and selection by address.
1.2. Setting function: You can set the initial parameters of the device, you can set the automatic meter reading cycle, the reading interval, etc. for the concentrator, and you can also set various parameters of the water meter.
1.3. Time calibration function: It can realize the system time calibration and the time calibration of the system to the concentrator.
1.4. Self-diagnosis and analysis functions: It can prompt users who may be faulty or suspected of water theft; and alarms for over-load limit and abnormal water consumption.
1.5. Data security protection function: Realize user management and system management through passwords or passwords, and set permissions to prevent unauthorized personnel from operating. The collection terminal and the carrier water meter are equipped with lead seals.
1.6. Extended functions: Freeze commands can be issued to freeze the accumulated water volume of the water meter at a specified time.
1.7. Data processing function: Including statistics of water meter data, such as calculation of line loss, report generation, etc.
1.8. Public database interface can be provided: water supply fee accounting, water management and other information system access
1.9. Data storage function
2. Project Features
2.1. Set the operating parameters of the concentrator: The system realizes the configurability of the management of the concentrator parameters, and the operation is more flexible and convenient.
2.2. Remote centralized reading of user water meter consumption: The concentrator automatically reads the water meter data during working hours, and saves and processes the reading data. When the concentrator completes meter reading, the main station establishes communication with the centralized and reads the concentrator directly Water meter data within.
2.3. Storing and counting user water data can generate reports and print them: The system saves various meter reading data and provides corresponding reports.
2.4. Analyze the user's water meter data in the distribution transformer station (small) area: Analyze the user's water meter data in various ways to fully grasp the operating status of the station's water meter, and deal with any abnormal problems in time.
2.5. Analyze the line loss of the station (small) area: The system provides a variety of line loss reports, including the daily, monthly, quarterly, and annual line loss of the station area, and the line loss of the day, month, quarter and annual phase. Segment line loss. To
2.6. Statistics station (community) area water consumption and user water consumption: Count the corresponding daily, monthly, and annual water consumption by station (small) area and user.
2.7. Security management: using Oracle or Microsoft SQL
The Server database guarantees the safe and stable operation of data, and encrypts and stores the password of the system operator. Data backup: regularly back up the database to ensure data security. Provides import and export functions for the basic file information of the system, and realizes the portable processing of data. Management authority setting: The system provides complete authority management, which realizes the function module level authority assignment; assigns corresponding management authority to different operators, and realizes the data layer authority control. System log: The system records the operation log of each operator, which provides a basis for troubleshooting.
2.8. Anti-stealing water function: Directly read the reading changes of the previous user's meter through the meter monitoring function, so as to achieve the effect of combating water theft
2.9. Automatic meter reading: The meter reader first sets the meter reading task. After the system detects that the task start conditions are met, it automatically performs meter reading and saves the corresponding data. To
2.10. Seamless connection with the hydraulic marketing system: User information can be obtained directly from the hydraulic marketing system and kept synchronized with the hydraulic marketing system. The meter reading results can be manually or automatically imported into the hydraulic marketing system for marketing charge statistics.
2.11. System flexibility: This system comprehensively applies multiple communication methods such as wireless communication, low-voltage carrier communication, and wired network data communication to the entire management system.
