Remote management system for ammeter data

Abstract

This invention relates to a remote management system for ammeter data. With power line carrier as main communication channel, the system comprises a meter reading terminal, a concentrator with a transformer electrical-energy acquisition module composed by a current / voltage sample circuits, and a main-station computer. This invention realizes both remote communication and the combination of integrated meter reading and monitor control, and improves department management level greatly.

Description

technical field [0001] The invention relates to a remote management system for electric meter data, in particular to a remote reading, monitoring and management system for electric meter data with power line carrier as the main communication channel, belonging to the technical field of power supply monitoring and management. Background technique [0002] The current power supply system supplies power to various users in the area through the transformer in the area. The electricity consumption of each user can be recorded by the household electricity meter. Through long-term relevant practice and in-depth research, the applicant of this patent realized that the total power consumption of each user should be equivalent to the power output of the transformer in the station area in theory. Therefore, in order to carry out scientific supervision and management of power supply, it is necessary to While mastering the metering data of each meter, real-time monitoring is performed o...

AI Technical Summary

Problems solved by technology

[0005] 1. The system does not have a master station, it can only collect data, and does not have data management and analysis functions;

[0006] 2. The second demodulation is fundamentally the modulation of data by frequency modulation. When the amplitude of the interference signal is larger than the signal amplitude, the data cannot be successfully transmitted (if the success rate of communication is to be ensured, the transmission power must be increased, and the result is The interference generated by the power grid will exceed the standard);

[0007] 3. The data acquisition terminal collects the meter data by accumulating pulses, and the pulse signals are easily lost when transmitted on long-distance wires

[0011] 2. Resources cannot be shared - the reading and management of residents' electric meters, the operation status of distribution transformers, the management of power consumption of large users, and the line loss of transformers in the station area are all very important to the power supply marketing department and are relatively independent The system prevents on-site data from being shared, which is very cumbersome to use and difficult to meet the needs of modern management

[0012] 3. Waste of channel resources - a relatively independent system, channels cannot be shared, increasing system operating costs
