Power supply line current signal wireless acquisition three-phase synchronous circuit

Abstract

The invention discloses a power supply line current signal wireless acquisition three-phase synchronous circuit, the output end of a transformer is connected with a power supply line, a detection module is communicated with the power supply circuit through the three-phase synchronous circuit, the three-phase synchronous circuit is provided with a current induction resistor and an ammeter, and thecurrent induction resistor and the ammeter are connected in series. A signal transmission module is further arranged in the detection module, a signal receiving module is arranged in the signal receiver, the signal transmission module transmits electric signals to the signal receiving module, a signal converter and a PLC control module are further arranged on the signal receiver, and the signal converter converts the transmitted electric signals into digital signals. The digital signal is transmitted to the PLC control module. The detection module transmits current data to the signal receiverin a wireless mode, the signal receiver feeds back current signals to the transformer through the PLC control module, the transformer changes the voltage class according to the received data, and stable power output of the executing mechanism is guaranteed.

Description

technical field [0001] The invention relates to the field of signal acquisition, in particular to a three-phase synchronous circuit for wireless acquisition of current signals of power supply lines. Background technique [0002] Electric energy has become an important energy source that cannot be obtained in the current industrial development, and has become an important resource for the healthy development of industry, agriculture, national defense and people's livelihood. With the development of the country's industry, there are a large number of high-power devices at the execution end. These devices need to ensure sufficient output power during use. Once the voltage is unstable, such as the voltage is too small, the output power will be reduced. When the equipment is shut down and restarted, higher power input is required, resulting in waste of electric energy. When the voltage is too high, it is easy to burn the equipment and cause economic losses. Therefore, it is neces...
