Fecha de publicación: 23/10/2020 Fuente: Wipo "BigData" The invention discloses a data acquisition and processing device based on big data. The data acquisition and processing device comprises an outer protection shell body and a PLC circuit board which islocated in the outer protection shell body and is provided with an acquisition module, wherein ventilation and heat dissipation mechanisms are installed on the two sides of the interior of the outerprotection shell body correspondingly; and each ventilation and heat dissipation mechanism comprises an openable plate and a driving part, each driving part comprises a motor, each openable plate comprises a bottom outward-overturning side plate and a top inward-overturning side plate, and the bottom outward-overturning side plates and the top inward-overturning side plates are located in the twoside walls of the outer protective shell body. According to the data acquisition and processing device, the bottom outward-overturning side plates and the top inward-overturning side plates which aredriven by the motors are arranged, when the motors rotate, the bottom outward-overturning side plates overturn towards the outer side, and the top inward-overturning side plates overturn towards the inner side, such that the air inlet amount of the device can be increased, further upward moving heat can be guided when the top inward-overturning side plates overturn towards the inner side, and heatcan be discharged conveniently.
