Example Embodiment

[0028] The present invention will be further described below in conjunction with accompanying drawing.

[0029] see figure 1 , the user electricity consumption information collection system 100 is a system for collecting, processing and real-time monitoring of electricity consumption information of electric power users, and realizes automatic collection of electricity consumption information, abnormal measurement monitoring, power quality monitoring, power consumption analysis and management, and related information Publishing, distributed energy monitoring, information interaction of intelligent electrical equipment and other functions. The system mainly has three communication transmission lines, one is the GPRS data transmission channel 101, that is: the data transmission between the concentrator and the main station network; the other is the low-voltage power line carrier data transmission channel 102, that is: the concentrator and the collector ( or carrier meter); the t...

Abstract

The invention discloses a testing and debugging system for low-voltage meter concentrated reading districts. The testing and debugging system comprises a microprocessor, as well as a GPRS channel monitoring unit, a power line channel monitoring unit, an RS485 channel monitoring unit, an electric energy meter data collecting unit, an electric energy meter running state monitoring unit, an alternating current sampling unit, a parameter setting unit, an initializing unit, a data storing unit, a data transmitting unit and an interacting unit that are connected with the microprocessor respectively. According to the invention, the testing and debugging system can simultaneously monitor three communication layers of GPRS, carrier waves and RS485, and provides powerful technical supports for correctly and reasonably locating a concentrator and improving the success rate of meter reading; meanwhile, by the data monitoring of each communication channel in knotty districts, problems existing in the field can be judged comprehensively in order to devise reasonable solutions.

Description

technical field [0001] The invention relates to the field of electric meter reading and debugging, in particular to a testing and debugging system for a low-voltage centralized meter reading area. Background technique [0002] With the development of the electricity market, the power load has increased sharply, and marketing measures such as "one household, one meter" and direct supply to households have continued to deepen, and the workload of power supply companies' electricity transcription has expanded rapidly. The traditional way of meter reading is to manually copy the indications of the user's electric energy meter. There are many links of manual intervention, and it is inevitable that there will be "wrong copying, missing copying, and estimated copying". Therefore, using remote meter reading technology to improve power consumption management and optimize power market services is an urgent need for power supply companies. [0003] However, in the construction process...
