For above-mentioned weak point of the prior art, this utility model aims to provide a kind of collection accurate information, can control in real time and the information acquisition system communicated。
For solving above-mentioned technical problem, information acquisition system of the present utility model, including host computer, A/D change-over circuit, cpu chip, PWM outfan and analog input end, its described host computer is connected with cpu chip, driven by a communication chip between described cpu chip and host computer and be connected, described cpu chip is connected with PWM outfan, and described analog input end is connected with cpu chip by A/D change-over circuit, and described cpu chip and one On-off signal/output circuit connect。
Amplifying circuit and filter circuit it is disposed with between described analog input end and A/D change-over circuit。
Described A/D change-over circuit is AD976 transducer。
Described analog input end is made up of pressure transducer, pulling force sensor。
Described On-off signal/output circuit is velocity sensor。
Information acquisition system of the present utility model, it is connected with communication chip owing to driving between host computer and CUP chip, can realize controlling in real time and communicating, the voltage signal that the collection of information is gathered by pressure, pulling force sensor, input a/d converter after the amplification of amplified circuit, filter circuit filtering, then it is input in cpu chip again, then calculating corresponding with the data that user demarcates, just can obtain the weight of this detection object；The signal gathered by velocity sensor, corresponding speed is obtained after chip decodes, in this utility model, A/D change-over circuit adopts AD976 transducer, has 16 conversion accuracies, 100us conversion speed and 8 tunnel synchronous acquisition functions, substantially increases acquisition precision and collecting efficiency。
Accompanying drawing explanation
Fig. 1 is system block diagram of the present utility model。
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described。
As shown in Figure 1, information acquisition system of the present utility model, including host computer, A/D change-over circuit, cpu chip, PWM outfan and analog input end, its described host computer is connected with cpu chip, driven by a communication chip between described cpu chip and host computer and be connected, described cpu chip is connected with PWM outfan, and described analog input end is connected with cpu chip by A/D change-over circuit, and described cpu chip and one On-off signal/output circuit connect。The instruction sent by host computer, and the data that analog input end, On-off signal/output circuit and PWM outfan collect all are sent to cpu chip, it is analyzed calculating by cpu chip, then send to host computer, PWM outfan, On-off signal/output circuit and analog input end again and perform operation accordingly, it is connected with communication chip owing to driving between host computer and CUP chip, can realize controlling in real time and communicating。
Further, amplifying circuit and filter circuit it are disposed with between described analog input end and A/D change-over circuit。Adopt PID control method, make cpu chip output pulse signal control to the constant speed and permanent torsion reaching environment-friendly function。
Further, described A/D change-over circuit is AD976 transducer。
Further, described analog input end is made up of pressure transducer, pulling force sensor。The voltage signal that the collection of information is gathered with pulling force sensor by pressure transducer, input a/d converter after the amplification of amplified circuit, filter circuit filtering, then it is input in cpu chip again, then calculating corresponding with the data that user demarcates, just can obtain the weight of this detection object。
Further, described On-off signal/output circuit is velocity sensor。On-off signal connects remote signal, photosignal, is mainly used in remote control configuration and process judges, output switch parameter includes the output of ac/dc voltage, switching signal output and the PWM output that user sets；The signal gathered by velocity sensor, obtains corresponding speed after chip decodes。In this utility model, A/D change-over circuit adopts AD976 transducer, has 16 conversion accuracies, 100us conversion speed and 8 tunnel synchronous acquisition functions, substantially increases acquisition precision and collecting efficiency。
