Analysis of Function Characteristics of GPRS Remote Meter Reading System
With the rapid development of communication technology, people have put forward higher requirements for the services provided by the mobile network. The GPRS remote meter reading system (General Radio Packet Service) provides end-to-end, wide-area wireless IP connectivity. GPRS has the advantages of wide coverage, fast data transmission, real-time online, free sending and receiving, and fast login.
The GPRS remote meter reading system connects the meter reading equipment with the main station equipment through the GPRS network. The data is processed by the GPRS module and sent to the main station through the base station with the agreement to realize real-time monitoring of user energy consumption data. GPRS is used in the remote meter reading system, and the data is aggregated to the server through GPRS, which can quickly produce the characteristics of electricity statistical analysis, payment receipts, etc., and also provides equipment management functions.
1. The GPRS remote meter reading system adopts high reliability and low power consumption microprocessor, which has stable operation and long service life.
2. The terminal immediately logs in to the data server, establishes a TCP connection, goes online, and automatically reconnects when disconnected.
3. Support real-time data copy function: three-phase voltage, three-phase current, active power, reactive power, etc.
4. Support frozen data collection function: daily freeze power.
5. Support curve data acquisition function: record a data point every few minutes.
6. Support remote valve control function: The management party can remotely open the gate and adjust the load through the background management software according to the user's cost and the size of the load.
7. Support remote closing function: The management party can send electricity through the background remote control according to the user's payment, load size, etc.
8. Support remote setting of basic parameters of measuring points (voltage, current transformation ratio, etc.) and power purchase control, reminder alarm, terminal power protection input and release, terminal power protection time, automatic power protection time, etc.
9. Support equipment reminders: out-of-box warnings, over-temperature warnings, over-voltage warnings, overload warnings and other danger warnings.
The GPRS remote meter reading system implements data collection in different ways for different application scenarios and fields. As an industrial-grade data collector, wireless data collectors are used in complex and harsh industrial environments and have a high protection level. They are durable, stable, low power consumption, and long battery life.
