Introduction:

GPRS smart meter is a new generation of network remote cost control smart energy meter specially designed based on embedded software and hardware development platform using large-scale integrated circuits. We have adopted advanced technologies such as microelectronics, computer chip technology, and modern communication technology. It integrates advanced GPRS technology in the industry, combines our company's years of experience in GPRS remote meter reading and GPRS data transmission, and is a large-scale GPRS remote meter reading system with low cost and operating expenses, convenient networking, and strong scalability.

GPRS smart meter technical parameters:

Advantages of GPRS smart meter:

Communication mode: The communication channel adopts high-speed full duplex industrial grade GPRS/GSM/CDMA modules, supporting TCP/UDP/SMS wireless network communication mode;

Communication module: The wireless communication module adopts modular design and supports live hot plug and unplug. After replacing the communication module, no manual settings are required, and it can automatically recognize the wireless MODEM type and automatically switch on.

Acquisition module: Embedded with high-speed and high-precision AC voltage and current acquisition module, with high sampling accuracy and real-time and accurate energy measurement.

Measurement function: It can measure the combined active power, positive and negative active power, demand, combined reactive power, and four quadrant reactive power in a time-sharing manner, and has functions such as 485 communication and infrared communication.

Protector:

Embedded with highly confidential ESAM module to achieve secure authentication process between the electricity meter and the system master station, ensuring the security and integrity of data exchange with the system master station.

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

Three phase power supply (i.e. line power supply method), when any phase of the three-phase three wire or any two phases of the three-phase four wire are disconnected, the energy meter can still work normally.

In the absence of AC power, the energy meter can maintain data and keep the clock chip working.

Support online upgrade of local/remote software, limited to wireless communication modules, without affecting meter measurement.

GPRS smart meters can not only solve the problems of low efficiency, missed readings, estimated readings, and safety hazards in manual meter reading work. And it can also improve the management of the power sector; Not only does it save manpower and material resources, but it also improves work efficiency, providing real-time data for achieving off peak power dispatch, and providing accurate, efficient, and safe data information for improving the level of energy metering management. The entire system consists of two main parts, namely the building electrical energy information collection system and the meter reading management center system. The building electrical energy information collection system consists of two parts: smart meters and data collectors.
