Abstract
The invention discloses a power line carrier meter reading system including a power distribution transformer and a low-voltage power line, and is characterized in that the system also includes a concentrator, a power supply module, a current mutual inductor, a signal conditioning circuit, an analog-digital converter, a communication module and an acquisition terminal, wherein the acquisition terminal is connected with an electric meter and collects information, and the concentrator controls and collects the information of the acquisition terminal and sends the information through the communication module. The power line carrier meter reading system has the beneficial effects that the stability of the carrier current is controlled through the current mutual inductor, a signal processing circuit and a digital-analog converter, a carrier current signal is not damped during the electricity usage peak of users, and thus the carrier communication distance is increased, and carrier communication is more reliable.
Description
Technical field
The present invention relates to a kind of power line carrier meter reading system, belong to the application of the communication system of power line carrier data transmission.
Background technology
At present, traditional pattern of checking meter is that craft is checked meter, handheld terminal is checked meter and vehicular radio is checked meter, but increasing automatic meter reading system is automatically by extensive practicality at present, traditional pattern of checking meter efficiency, artificial on just there is larger waste, also have some carrier wave data sampling device for electric meters at present, this device is usually relatively simple for structure, by the humorous wave interference that consumer produces, carrier signal to noise ratio reduces greatly, and communication distance obviously reduces, even can not communication.
Summary of the invention
The object of the invention is just to overcome above-mentioned deficiency, provides the power line carrier meter reading system that a kind of communication is reliable and stable.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of power line carrier meter reading system, comprise substation transformer and low-voltage power line, also comprise concentrator, power module, current transformer, signal conditioning circuit, analog to digital converter, communication module and acquisition terminal, described acquisition terminal is connected with ammeter and Information Monitoring, and described concentrator is controlled the information of collection acquisition terminal and sent by communication module.
Further, described power carrier line is provided with repeater.
Further, described communication module is built-in with wireless communication unit and SIM card
The beneficial effect of power line carrier meter reading system of the present invention is: control the stable of carrier current by current transformer, signal processing circuit and digital to analog converter, carrier current signal decay when can not be subject to the peak of power consumption of user, and then carrier communication distance is increased, carrier communication is more reliable.
Accompanying drawing explanation
Fig. 1 is the present invention's electricity structural schematic block diagram;
Embodiment
As shown in Figure 1, current transformer is installed on a line of electric force, carrier current signal for carrier processor being sent is coupled to line of electric force, realize the series coupled of carrier current signal and power frequency current signal, acquisition terminal is connected with the ammeter of user, be sent to after collecting data in carrier processor, signal conditioning circuit comprises bandpass filter, for demodulating carrier current signal, its output terminal is connected with the input end of analog to digital converter, analog to digital converter is converted to the data of carrier current signal and is sent to carrier processor, by carrier processor, the data processing received is obtained to the communication data of carrier communication, the output terminal of carrier processor is connected with the input end of concentrator, concentrator is collected several acquisition terminals and is sent and sent by communication module after the signal processed.
