Product Introduction

The DJTL33-YBFD201 intelligent simulation concentrator is a 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. The main application is to collect system training equipment and simulate scenarios such as power companies, public utilities, public buildings, and residential areas at all levels. When used as a training function, the concentrator has special teaching functions and can achieve functions such as setting terminal error parameters, simulating terminal operation faults, and setting terminal abnormalities through the internal terminal.

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 indicator light malfunction, etc.

Adopting industrial grade ARM9 series system motherboard and LINUX operating system.

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

Upstream communication adopts communication methods such as GPRS/CDMA/4G, Ethernet, fiber optic, etc.

The downlink communication adopts 485 bus communication.

Main technical parameters

Typical applications

The DJTL33-YBFD201 intelligent simulation concentrator is widely used in online loss training, equipment management, low-voltage collection and reading training equipment. At the same time as centralized meter reading, it completes functions such as monitoring and data statistics of distribution transformers in the substation area, and cooperates with the main station system to form a remote centralized meter reading system for electricity automation. This has positive significance for training and research on how to improve the efficiency of centralized meter reading in residential areas and reduce line losses.
