Product Introduction

The TLY2290 concentrator is an important component of the low-voltage centralized meter reading system, which can communicate with the main station through 4G/3G/GPRS/CDMA, Ethernet/fiber optic, and other methods; RS485 communication is used to achieve functions such as receiving, storing, summarizing, and transmitting electricity meter data. Mainly used in various levels of power companies, public utilities, public buildings, residential areas, and other places.

Product features/main functions

● Terminal communication failures: Terminal not online (poor signal strength), Ethernet module failure, unstable installation of SIM card, SIM card damage, poor contact of communication module, abnormal GPRS communication.

● Terminal parameter faults:

Terminal uplink communication parameter errors: incorrect main station IP address, incorrect main station port number, incorrect terminal IP address, incorrect terminal administrative area code, incorrect terminal address, and incorrect terminal uplink communication protocol.

Terminal downlink communication parameter error: The information of the terminal measurement point and the energy meter under the measurement point are inconsistent, the communication address of the energy meter under the measurement point is inconsistent with the actual corresponding energy meter address, the communication baud rate of the energy meter under the measurement point is inconsistent with the meter baud rate, the communication protocol of the energy meter under the measurement point is inconsistent with the meter communication protocol, and the access circuit of the energy meter under the measurement point is inconsistent with the actual access circuit of the meter.

Terminal hardware failures: terminal failure to start, terminal white screen, terminal black screen, terminal splash screen, etc.

Adopting industrial grade Cortex-M3 series controllers and embedded operating systems.

Excellent electromagnetic compatibility performance, able to resist interference from high voltage spikes, strong magnetic fields, strong static electricity, lightning surges, and has strong environmental adaptability.

The uplink communication with the main station adopts wireless public network mode, compatible with communication methods such as GPRS/CDMA/4G.

The downlink communication is carried out using RS485 bus, etc.

The wide voltage range design makes it more reliable and adaptable to the working environment.

Main technical parameters

Typical applications

Used for low-voltage electricity information collection simulation training system, the simulation concentrator is used as a training device with special teaching functions. It can set terminal error parameters, simulate terminal operation faults, and set terminal abnormalities through the internal terminal. By cooperating with fault setting software, terminal fault points can be set. It can be used for student training, skill assessment, skill competitions, etc. in power harvesting systems.
