Detailed Explanation of The Principle of Remote Power Meter Reading Collector

To achieve remote power meter reading, a smart meter needs to use a third-party device to transmit the meter data to the remote meter reading system platform. The collector plays exactly this role. Through the collector, the automatic collection, storage and forwarding functions of various electric energy can be realized. Then, the system automatically processes and generates various types of data reports, which can be viewed by managers through a computer or mobile phone. Does the function of the collector look very intelligent, but the principle is not complicated. Let me explain it to you below.

Introduction to the principle of the collector

The collector adopts advanced 32-bit ARM hardware platform and RTOS operating system platform as the core and uses LoRa wireless and RS-485 as data link. It is an embedded collector product with stable performance and reliable operation.

The collector communicates with the meter's RS-485 interface through its own RS-485 interface. After collecting the relevant data of the meter, the carrier/wireless channel transmits the collected data to the concentrator, and finally to the background system. The instructions or parameters of the background management system can also be downloaded to the meter according to the system function.

Simply put, the collector is the "middleman" between the meter and the concentrator (meter-collector-concentrator), and it needs to be connected to the top. It can not only upload data in response to the command of the concentrator, but also download and execute commands to the meter.

The main function

* Collection: Automatically collect energy meter data according to the collection period set by the concentrator.

* Storage: classify and store data and save the total active energy data of key user energy.

* Event record: record events such as parameter change, meter reading failure, terminal shutdown/power-on, etc.

* Parameter setting: Communication parameters can be set through LoRa wireless and RS-485, including LoRa wireless communication frequency, LoRa network address, LoRa node address, 485 interface baud rate, etc.

* Data transmission:

a) Communicate with the concentrator, receive, and respond to the command of the concentrator, and transmit data to the concentrator.

b) Relay forwarding, which supports communication relay forwarding between the concentrator and other collectors.

c) Communication conversion, the collector can convert the communication mode and communication protocol of the upper and lower channels.

d) For collectors with storage function, security measures should be taken for the transmission of important data.
