1. Adopt flame-retardant shell, light in size and easy to install
2. Modular design, CDMA module and GPRS module are interchangeable, automatic identification
3. Three-phase power supply, the terminal works normally under the condition of arbitrarily breaking the two-phase voltage
4. Collect real-time energy indication value of each energy meter, daily zero-point frozen energy indication value, meter reading day zero-point frozen energy indication value
5. The meter reading scheme can be set and inquired remotely or locally
1. Data collection
The concentrator collects the real-time energy indication value of each energy meter, daily zero-point frozen energy indication value, and meter reading day-zero frozen energy indication value. Energy data should be saved with a time icon.
2. Data storage
The concentrator can classify and store the collected data as required, such as daily frozen data, meter reading daily frozen data, curve data, historical monthly data, etc.
3. Parameter setting
Clock call measurement and timing function: Correct time for the system and the energy meter.
Terminal parameter setting and query: remote query from the master station or local setting and query from the handheld device
Meter reading parameters: remote or local setting and query meter reading scheme
4. Event record
The concentrator is divided into important events and general events according to the set event attributes. Events include terminal parameter changes, meter reading failure, terminal power off / on, energy meter clock out of tolerance, etc., and can save the latest 500 event records.
5. Local functions
The concentrator has a local maintenance interface, supports handheld device setting parameters and on-site reading of electrical energy data, and has security measures such as authority and password management to prevent operation by unauthorized personnel.
The concentrator has a local communication interface, can read the data of the assessment table in the station area, and can support the communication of the mining equipment and reactive power compensation device for distribution transformer monitoring.
