Product Description

TimeWave Cat.1 communication module-TW-Cat1 based on edge computering to realize independent installation of smart meter


TW-Cat1 is a communication module for single and three-phase smart watt hour meters based on edge computing. Realize independent installation of single and three-phase intelligent energy meters. The electrical interface is unified, avoiding the secondary development of the electric energy meter.

Cat1 (4G) smart meter communication module is embedded with a network communication module with LET Cat.1 and GPRS dual-mode and a high-speed 32-bit microprocessor. As long as the use environment of smart electricity meters is within the scope of Cat1 communication network, the instant access management platform of electricity meters can be realized. Receive and respond to the reading/control instructions issued by the platform. At the same time, it can automatically acquire various data of the electric energy meter by effectively controlling the upload cycle and reporting tasks and other operating parameters within the communication module. Regularly and actively upload to the cloud platform. The communication module can directly replace the PLC module or small wireless module of the current electricity meter. Realize Cat.1 network access and establish connection with the specified server platform through TCP protocol.


Main functions and features

  • The standard smart meter communication interface and module box design of the State Grid are adopted. It is suitable for most smart meters. It can be replaced directly (hot plug).
  • The communication module has the ability to automatically obtain the unique communication address information of the currently equipped smart meter after power-on. It is bound to its own remote communication address.
  • The communication module configures the operation parameters such as upload task list and upload cycle time. It can automatically read the specified data of the electricity meter and upload it to the service platform;
  • Professional interface data flow automatic control technology. Give priority to the instruction frame issued by the platform gateway to complete real-time two-way transparent transmission;
  • The status indication of communication module is rich. The working status of the module can be determined by the status indicator on site.
  • The configured parameters can be saved when the communication module is powered down. Automatic recovery when power is restored.
  • Low latency, 4G network bearer. Millisecond delay experience.
  • Based on the existing operator network. Wide coverage and high stability.
  • SIM card plug and play. Support the 4G networks of three operators, namely, China Telecom, China Mobile and China Unicom;
