Abstract
The utility model discloses a remote electric energy quality monitoring system, which comprises microprocessors of a plurality of electric energy quality monitors and further comprises a concentrator, a second modulator-demodulator and a plurality of first modulator-demodulators, wherein the first modulator-demodulators and the microprocessors of the electric energy quality monitors are as many as each other in quality and are connected correspondingly one by one; a plurality of first modulator-demodulators are connected with an input interface of the concentrator by a public fixed-line telephone network; an output interface of the concentrator is connected with the second modulator-demodulators; and the second modulator-demodulators are further connected with a communication interface of a computer. The remote electric energy quality monitoring system can directly perform real-time monitoring on a plurality of electric energy quality monitors in a remote computer without using labor cost, so the monitoring cost is low. The remote electric energy quality monitoring system has good real-time performance due to the direct on-line communication monitoring.
Description
Technical field
The utility model relates to a kind of equipment for monitoring power quality on a plurality of nodes in the electrical network that is installed in, and specifically is a kind of Long-distance monitoring for electric power quality system.
Background technology
At present, in electric energy quality monitoring system, electric energy quality monitor is on any node that is arranged in the electrical network in use, and a plurality of nodes generally can be set on the electrical network, so the difference of electric energy quality monitor is very wide.Because electric energy quality monitor is generally on-the-spot on-Line Monitor Device, so each node all must arrange two or three people to carry out on-site supervision, so not only monitors the cost height, and real-time is relatively poor.
The utility model content
The technical problem that the utility model will solve is, overcomes the defective of above prior art, provides a kind of real-time the good and low Long-distance monitoring for electric power quality system of monitoring cost.
The technical scheme of the utility model is; A kind of Long-distance monitoring for electric power quality system is provided; The microprocessor that comprises a plurality of electric energy quality monitors; It also comprises a hub, a second modem and a plurality of first modulator-demodulator, and described first modulator-demodulator equates with the quantity of the microprocessor of electric energy quality monitor and connects one to one; Be connected through public fixed-line telephone network between the input interface of described a plurality of first modulator-demodulator and hub; The output interface of said hub is connected with second modem; Described second modem also is connected with the communication interface of computer.
The communication interface of the interface of the interface of the microprocessor of said a plurality of electric energy quality monitors, the communication interface of said computer, hub, said first modulator-demodulator and second modem is the RS232 communication interface.
After adopting above structure, the utility model compared with prior art has the following advantages:
The utility model Long-distance monitoring for electric power quality system can directly carry out the real-time monitoring of a plurality of electric energy quality monitors at long-range computer, owing to do not need cost of labor, it is low therefore to monitor cost.Owing to be direct online communication monitoring, so real-time is good.

Accompanying drawing is the system construction drawing of the utility model Long-distance monitoring for electric power quality system.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Shown in accompanying drawing; A kind of Long-distance monitoring for electric power quality of the utility model system; The microprocessor that comprises a plurality of electric energy quality monitors; It also comprises a hub, a second modem and a plurality of first modulator-demodulator, and described first modulator-demodulator equates with the quantity of the microprocessor of electric energy quality monitor and connects one to one; Be connected through public fixed-line telephone network between the input interface of described a plurality of first modulator-demodulator and hub; The output interface of said hub is connected with second modem; Described second modem also is connected with the communication interface of computer.The Modem that modulator-demodulator is promptly commonly used, that use in the present embodiment is the TW-EC5658V of TPLINK.
The communication interface of the interface of the interface of the microprocessor of said a plurality of electric energy quality monitors, the communication interface of said computer, hub, said first modulator-demodulator and second modem is the RS232 communication interface.
The dialer software of electric energy quality monitor is housed in the computer.
The computer that controller programming software is housed promptly can carry out remote monitoring to the real time status in the electric energy quality monitor.
Confirming that connection connects under the normal situation; And then open the computer that the electric energy quality monitor communication software is housed; Modulator-demodulator Modem, public telephone network through the warp of the dialer software in the computer second; The first modulator-demodulator Modem to assigned number dials, and sets up communication channel.Through this communication channel of setting up, the data in the electric energy quality monitor are monitored, thereby learnt the operation conditions of electric energy quality monitor.
Below only be described, but can not be interpreted as it is restriction claim with regard to the most preferred embodiment of the utility model.The utility model is not limited only to above embodiment, and its concrete structure allows variation.In every case the various variations of in the protection range of the utility model independent claims, being done are all in the protection range at the utility model.
