Abstract

The present invention discloses a distributed data acquisition device based on a microprocessor. The distributed data acquisition device based on the microprocessor comprises a plurality of distributed prepositive workstations, an RS232 bus, and a simulation multi-path switch control unit connected with a PC. Each distributed prepositive workstation is composed of a signal conditioning circuit, the microprocessor with a multi-channel A / D converter and an RS232 communication interface, and the simulation multi-path switch control unit comprises a communication interface expansion circuit, the microprocessor and the RS232 communication interface. The data acquisition device can obtain the multi-channel data synchronously and real-timely, adopts a distributed structure, forms a data detection network by the cooperation of the plurality of workstations, is flexible in system layout, simple and convenient in channel expansion, low in cost and good in low power consumption performance, at the same time, avoids the resource waste effectively, and also has the very high reliability and the good data real-time performance on the condition of many channels, and can satisfy the actual application requirement.

Description

technical field [0001] The invention relates to data acquisition technology, in particular to a microprocessor-based distributed data acquisition device. Background technique [0002] At present, in industrial production and many other occasions, considering product quality, equipment performance and other issues, it is usually necessary to monitor some parameters on site, and data collection is essential in this process. The application data acquisition device can obtain the instantaneous information of the measured object in real time, can effectively monitor the changes of the measured object, and reflect the equipment failure or product performance influencing factors, etc., which is beneficial to the observer to make reasonable arrangements for the on-site situation. Therefore, the data acquisition device has more and more extensive application fields, providing convenient conditions for humans to effectively obtain various information. [0003] However, traditional da...
