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 ea

Embodiment 1

[0034] The electric meter data remote management system of the present embodiment is as shown in Figure 7, mainly due to the meter reading terminal for reading the electric meter, the concentrator for receiving and uploading the reading and transformer data in the station area, and the computer as the main station of the management center constitute. The meter reading terminal can use various existing similar devices for carrier data transmission. Its signal acquisition end is connected to an external meter through an interface circuit, and its signal output end is coupled to the power supply line through a carrier modulation and demodulation circuit. The concentrator contains a microprocessor, the signal receiving end of the microprocessor is coupled and connected with the power supply line through the carrier modulation and demodulation circuit, and the communication end is connected with the remote channel through the communication interface. The master station computer can...

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...
