Power transmission real-time monitoring system

Abstract

The invention discloses a power transmission real-time monitoring system, which comprises a signal frequency acquisition circuit, a phase shift feedback circuit and a frequency selection output circuit, and is characterized in that the signal frequency acquisition circuit adopts an SJ-type; A signal frequency collector J1 of the ADC collects the frequency of a data signal received by a control terminal in the power transmission real-time monitoring system. The phase shift feedback circuit uses an operational amplifier AR1, resistors R5 to R8 and a capacitor C3. the capacitor C4 forms a phase shift circuit to adjust the signal pulse width; A triode Q1 and a voltage-regulator tube D7 are used for voltage stabilization and then input into the in-phase input end of an operational amplifier AR4, a triode Q2 and a capacitor C6 are used for feeding back signals to the base electrode of a triode Q3, a triode Q4 is used for feeding back signals to the emitting electrode of the triode Q3. Finally, the frequency selective output circuit uses a resistor R16-resistor R18 and a capacitor C8-capacitor C10 to form a frequency selective circuit to screen out a single frequency signal output., so that the frequency of a data signal received by a control terminal in the power transmission real-time monitoring system can be monitored in real time, and signal frequency modulation and voltage stabilization are carried out.

The power industry provides a steady stream of electric energy for the development of the social economy. Its transmission lines, high-voltage towers, substations and other facilities all over the country are in daily operation. At present, the application of real-time monitoring system for power transmission has developed accordingly, which greatly saves It saves manpower and material resources and improves the efficiency of power energy detection. However, in practice, due to the variety of environments in the power transmission process, the data signals collected by the acquisition module of the power transmission real-time monitoring system are in the wireless transmission process, especially when encountering strong magnetic fields. When the frequency hopping and attenuation often occur, it will seriously affect the results of the analysis data of the control terminal in the power transmission real-time monitoring system
