The remote meter reading control and management system mainly consists of electric energy meters, relay distributors, transmission networks, communication adapters or communication machines, Wangkong computers, and management software.
Computers exchange data with energy meters through transmission networks, and perform calculations, queries, statistics, printing, parameter settings, and power outage control to achieve functions such as electricity bill settlement and control.
The electric energy meter is equipped with a dedicated communication interface, which can be connected to A485 bus network, local area network, wireless network, telephone network and other transmission networks through a communication adapter or communication machine. The connection methods are diverse and the project cost is low.
※ Electric energy meter: Select the DDSH1899 series electric energy meter produced by Shanghai Huile Electric Co., Ltd.
The communication adapter selected is the HLTXSB-1 type communication adapter produced by Shanghai Huile Electric Co., Ltd. Its main function is to connect multiple energy meter collectors to remote computers through RS485 bus or other transmission networks to achieve data network transmission.

★ Technical indicators:
※ Capacity: 32 devices (electric meter or collector)
※ Communication distance: 1200 meters
※ Power supply: 5V
※ Power consumption: ≤ 1W
Enhanced relay distributor: HL485 relay distributor produced by Shanghai Huile Electric Co., Ltd. should be selected. When the distance between the communication adapter and the remote meter or collector exceeds 1200 meters, a relay distributor should be added to amplify the communication signal and extend the communication distance.

★ Technical indicators:
※ Capacity: Each channel contains 32 485 devices (electric meters or collectors), divided into 1-channel type (HL485-H1), 2-channel type (HL485-H2), and 4-channel type (HL485-H4)
※ Extended distance: 1200 meters
※ Power supply: 5V
※ Power consumption: ≤ 1W
Central management computer: Windows platform, Pentium multimedia computer. Centralize the management of data transmitted through electric energy meters or collectors
※ Communication cable: It is recommended to use Category 5 UTP cable (Ethernet cable):
Management software: The management software mainly realizes data communication between devices and monitors, manages, stores, records and other functions of the entire system's operation status.
※ Transmission network equipment: Common transmission network equipment includes RS-485/Ethernet network adapters, wireless data transmission terminals, GPRS wireless meter reading terminals, wired telephone communication adapters, etc. Please refer to the "Introduction to Common Devices in Transmission Networks" for details.
※ Display and prompt devices: LED dynamic information display screen, SMS reminder MODEM, etc. Please refer to the "Introduction to Common Devices in Transmission Networks" for details.

★ Characteristics and main functions of management software
Meter reading and electricity sales function: By using management software in the management center, the system can read data from various electricity meters and sell electricity with an accuracy of 0.01 degrees.
※ Parameter setting function: Various parameters can be set according to different types of energy meters through the management software in the management center.
※ Control function: Control the user's power on/off status through the computer.
※ Modification function: The system has functions such as resident information modification and setting.
※ Cost settlement: The system calculates the user's fees based on meter reading or electricity sales records, and implements the average or proportional allocation of public energy losses to each household, automatically calculating the fees payable by each household, in order to charge the user.
※ Query function: (1) Single household query: You can query the sales records or remaining electricity of any household at any time.
(2) Query on each floor: You can check the electricity sales records or remaining electricity of all residents on any floor at any time.
※ Printing function: It can print electricity sales records for each user, as well as a total list of all users and a single user list.
※ Data backup function: The system has a data storage set backup function.
※ Anti cheating function: The system implements authorized password operations, and a dedicated person can operate with the password. The system also has a running log that can record the operator's operation process in detail.
※ Account opening and closing function: The system implements management functions such as opening and closing accounts, changing rooms, and refunding fees for users.
※ Data filtering function: The system can filter and analyze the remaining power of users based on the set value, reminding users to purchase electricity in a timely manner.
