Problems solved by technology

[0002] At present, green building monitoring equipment mainly includes a signal transmitter, a signal receiver, and a controller. The signal sent by the signal transmitter is transmitted by a carrier signal, and the carrier signal will accumulate noise during transmission. When the noise accumulation is too large, it will cause data The signal is lost, resulting in a decrease in the accuracy of the signal received by the control terminal, or even an error signal, which seriously affects the analysis and data monitoring of the data signal by the controller

Abstract

The invention discloses green building monitoring equipment based on big data. The equipment comprises a waveform detection module, a signal conditioning module and an operational amplifier transmitting module; the waveform detection module uses a detector J1 with the model of AD 8313 to collect carrier waveforms when the signal emitter works. The signal conditioning module uses an operational amplifier AR2, an operational amplifier AR3 and a diode D3 to form a pulse width amplification circuit. Capacitors C3 to C7 and a triode Q3 are used to form a frequency modulation circuit to select the frequency of the signal. Finally, the triode Q1 and a triode Q2 are used to form a push-pull circuit to prevent signal crossover distortion, and the operational amplifier transmitting module performs in-phase amplification by using an operational amplifier AR1 and then transmits the amplified signal to a green building monitoring controller through a signal transmitter E1, so the accuracy of an error reference signal of the controller is improved, and the controller can analyze whether a data signal is accurate or not conveniently.
