Problems solved by technology

[0002] In recent years, with the continuous deepening of project lean management requirements, the original manual estimation method can no longer meet the current business requirements. Therefore, combined with the current information technology, the engineering project bidding information management system based on big data is The future development trend is to establish a standardized and scientific production project cost index calculation system to solve the current production projects that are characterized by large quantities, many types, scattered projects, and non-centralized business data. It is difficult for non-technical personnel to quickly, Accurately calculate the estimated amount of the production project. However, due to the complexity of the project cost information and the limitations of big data information transmission, there will be frequency hopping during the transmission process, and even strong magnetic interference, resulting in signal loss or signal distortion. , which will cause the engineering project cost information management system to bring unpredictable losses to the engineering project

Embodiment 1

[0012] Embodiment 1, an engineering project bidding information management system based on big data, including a signal sampling module and a calibration comparison module, the signal sampling module samples the signal of a big data node in the engineering project bidding information management system, and the signal sampling module Connect the calibration comparison module, and the output signal of the calibration comparison module is sent to the terminal of the engineering project bidding information management system based on big data through the signal transmitter E1;

[0013] Since the sampling signal of the big data node in the engineering project bidding information management system is a small signal, it is unstable. Distortion will not occur, so the calibration comparison module first uses the op amp AR1, the op amp AR2, the diode D2, and the diode D3 to form a conditioning circuit to adjust the signal waveform, and the capacitor C2 prevents the output signal from the ...

Embodiment 2

[0015] Embodiment 2. On the basis of Embodiment 1, the signal sampling module selects the signal sampler J1 of the model DAM-3056AH, and uses the inductor L1 and the capacitor C1 to filter out signal clutter at the same time, and performs preprocessing for the next step of signal adjustment. , the power supply terminal of the signal sampler J1 is connected to the power supply +5V, the ground terminal of the signal sampler J1 is grounded, the output terminal of the signal sampler J1 is connected to the negative pole of the voltage regulator D1 and one end of the resistor R1 and the capacitor C1, and the voltage regulator D1 The positive pole is grounded, the other end of the resistor R1 is connected to the other end of the capacitor C1, the resistor R2, and one end of the inductor L1, and the other end of the resistor R2 is connected to the other end of the inductor L1 and the signal input port of the calibration comparison module.

Abstract

The invention discloses an engineering project bidding informatization management system based on big data. The device comprises a signal sampling module and a calibration comparison module, the signal sampling module samples big data node signals in the engineering project bidding informatization management system. The signal sampling module is connected with the calibration comparison module; the calibration comparison module firstly uses an operational amplifier AR1, an operational amplifier AR2, a diode D2 and a diode D3 to form a conditioning circuit to adjust a signal waveform. Then, anoperational amplifier AR2 is used for further following the signal; meanwhile, a diode D2 and a diode D3 are used for limiting an output signal peak value of the operational amplifier AR2; precise calibration of signals, an operational amplifier AR4, a diode D4 and a diode D5 are used to form a peak detection circuit to screen abnormal signal peaks. And finally, a signal is fed back to the inverting input end of the operational amplifier AR3, so that the effect of two-stage calibration of the output signal of the engineering project bidding informatization management system terminal based on big data is achieved, and the engineering project bidding informatization management system terminal analyzes and responds in time.
