Application of Lora Energy Meter in Substation
Although the technology level of today is high than yesterday, electricity is still an important source of national development and social stability. The rapid growth of power distribution has also brought many problems. In the case of the wide distribution of meter installation sites or tight wiring, the traditional wired communication method is far from meeting customer needs. With the vigorous development of wireless communication, as a device that can provide data viewing and reference in times when equipment and lines are inconvenient to connect and obtain data, it is particularly convenient and important to use in these special places. And LoRa is common in wireless communication technology. Remote meter reading has become an important part of the smart grid.
Compared with the complex and troublesome wiring of traditional meters and reading data, the demand for wireless technology has emerged as the times require. With the development of low-power wide-area connectivity requirements of the Internet of Things, LoRa technology has also brought new opportunities to our meter's IoT wireless solutions. Due to the openness of LoRa, various business models have been formed in market applications.
The existing electric meter communication mode is mainly through RS485, Ethernet, or Profibus communication. This communication method requires a special line connection, and the high cost of wiring is not conducive to large-scale popularization and use. Relying on 4G, NB, and other wireless communication technologies can reduce wiring costs. AS its communication range is only suitable for base station wireless communication and the cost is high, it is not suitable anywhere that meter installation sites are widely distributed.
Using LoRa communication meter, not only has the characteristics of wide coverage, low communication cost, high efficiency, real-time transmission, etc. but also improves the standardization of management of meter reading business, solves the weak point of cumbersome wiring, and solves the problem of difficult management of distribution and distribution.
The LoRa communication instrument can not only be connected to the monitoring host through wired communication but also can be connected to the safety power management cloud platform or other cloud platforms through LORA communication, which is convenient for managers to maintain all places where electrical safety products are installed.
The LoRa communication instrument is installed in the drawer cabinet of the substation, which can not only detect the electrical parameters and electric energy of each circuit in real-time, but also eliminate the communication connection with the back of the system, communicate with the gateway of the incoming cabinet through LoRa, and upload it to the background.
We have a Din rail Lora WAN energy meter, single-phase wall-mounted Lora WAN electric meter, three-phase Lora WAN electric meter, etc. Our Lora WAN electric meter can monitor electric parameters in real-time and send data to the backend and cloud platform through a gateway or Lora WAN wireless communication technologies. There is no complex communication line. When the electricity consumption is abnormal, the user can directly check the data and analyze and troubleshoot.
