Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
In the utility model embodiment, a kind of high-precision transmission line of electricity electric current on-Line Monitor Device is provided, as shown in Figure 1, this device comprises measurement mutual inductor, gets energy mutual inductor, responds to electricity-fetching module, current measurement module, main control unit, GPRS communication module, get and can be connected with the input end of induction electricity-fetching module by mutual inductor, measure mutual inductor to be connected with one end of current measurement module, the output terminal of induction electricity-fetching module is connected with one end of current measurement module, main control unit, GPRS communication module respectively, and the other end of current measurement module is connected with main control unit; GPRS communication module is connected with main control unit; Induction electricity-fetching module is used for for current measurement module, main control unit, GPRS communication module are powered; Current measurement module is for gathering current signal; The current signal that main control unit is used for current measurement module to send is sampled and is calculated, and obtains primary current value, and communicates with GPRS communication module, obtains current time and address information; GPRS communication module is used for the data of main control unit to be sent to background system or portable equipment by GSM network.
Wherein, current measurement module comprises filtering circuit, power chip, MCU, and measure the output terminal of mutual inductor and be connected with one end of filtering circuit, the other end of filtering circuit is connected with one end of power chip, and the other end of power chip is connected with MCU, as shown in Figure 2.
Induction electricity-fetching module part, is designed to carry out energy storage within the free time of measuring interval, even if to ensure when primary side current is less, also has enough energy to carry out primary current and measures and data transmission.
Main control unit adopts high-performance processor, and the current signal sent by current measurement module sampling and calculating, obtain primary current value, and communicate with GPRS communication module, obtains current time and address information.Wherein current measurement module part is primarily of measurement mutual inductor, filtering circuit, power chip, MCU composition.As shown in Figure 3, primary side big current changes into less secondary side current through high-precision measurement mutual inductor, because power chip, single-chip microcomputer all can only process the electric current of milliampere level, so add a high-precision sample circuit in the design, secondary side current is changed into the manageable electric current of power chip.Power chip needs to calibrate before use, and in order to improve precision, the calibration instrument precision that we use is 0.1%.Then, MCU reads current value from power chip, carries out the data processing of being correlated with, finally obtain precision up to 0.1% current value.Main control unit also possesses power management function, when measuring interval, the power supply of other modules such as GPRS communication module can be cut off, enter park mode, only recover normal mode of operation when current measurement time arrives, complete current measurement, open GPRS module transmission data, again enter park mode afterwards, to reduce power consumption.
The utility model mainly obtains the real-time current on transmission pressure by the current measurement integrated circuit designing a kind of high precision (measuring error is lower than 0.1%) low-power consumption, then communicated by GPRS.The effect of electricity getting device is the voltage providing+5V to main control unit, and the effect of GPRS communication module is that the data recorded are sent to background system or portable equipment by GSM network.When the current value that backstage or portable equipment monitor is unreasonable, monitor staff just can carry out the process of being correlated with according to the position of trouble spot in time.This apparatus design is advanced, rational in infrastructure, and safety and stability is reliable, and prediction is accurate, is very good transmission line of electricity current monitoring device.
