Description
Technical field
The present invention relates to a kind of monitoring device for power user power consumption information acquisition system.
Background technology
Power user power consumption information acquisition system (power user electric energy data acquire system) is the system gathering the power information of power consumer, process and monitor in real time, realizes the functions such as the automatic collection of power information, metering exception monitoring, electric energy quality monitoring, electrical energy consumption analysis and management, relevant information are issued, distributed energy is monitored, the information interaction of intelligent power equipment.
Refer to Fig. 1, the concentrator 2 that power user power consumption information acquisition system generally comprises main website 1, several one_to_one corresponding are installed in each small area, several to be installed near electric energy meter in each described small area 4 and the collector 3 be connected with at least one electric energy meter 4.Power user power consumption information acquisition system mainly contains three communications circuits (i.e. communication channel), and one is GPRS data transmission channel, the transfer of data namely between concentrator and main website networking.Two is low voltage power line carrier data transmission channels, the transfer of data namely between concentrator and collector.Three is RS485 data transmission channels, the transfer of data namely between collector and electric energy meter.
GPRS is communicated, the height of GPRS signal strength signal intensity, the direct rate of reaching the standard grade affecting concentrator, ensure that the concentrator rate of reaching the standard grade is the necessary condition ensureing stable success rate of checking meter, because of concentrator erecting bed more complicated, lack necessary means of testing, be difficult to the signal strength signal intensity determining infield in a pre-installation, only can after concentrator be installed, judged by " concentrator reach the standard grade rate ", as signal strength signal intensity is too low, just need by reload signal amplifier, the method of extension antenna or replacing concentrator position solves, extra equipment will be increased like this, also add a lot of debugging cost, for low-voltage powerline carrier communication, power line communication (Power line communications, PLC) is a kind of communication mode using power line as communication medium.Power line is not a kind of desirable communication media at all times, but along with the continuous progress of technology, the particularly development of modulation technique and microelectric technique, the practical of PLC is made to become possibility, because power line is non-dedicated communication line, wherein the feature such as time variation, randomness of various interference, selects suitable carrier communication chip to seem even more important; For RS485 communication, the quality of 485 ports (namely showing meter 485 port) of electric energy meter directly will affect success rate of checking meter, and how his-and-hers watches meter 485 port fast detecting is just particularly important.
In power user power consumption information acquisition system process of construction, lack relevant monitoring device, power user power consumption information acquisition system construction is only constructed by rule of thumb, the only construction and installation by rule of thumb of the installation phase place of the installation site collector of such as concentrator and position, the quality of table meter 485 port cannot be determined in advance.Because impact is checked meter, success rate is a lot of with the factor of stability of checking meter, and site installation test workload is very big, and the monitoring device substantially not having power user power consumption information acquisition system special.
