Novel intelligent liquid level measuring instrument based on machine vision

Abstract

The invention discloses a novel intelligent liquid level measuring instrument based on machine vision. The novel intelligent liquid level measuring instrument comprises an industrial liquid level meter, a CMOS camera module and a PC client side; and the CMOS camera module collects liquid level images of the industrial liquid level meter and is connected with an Internet gateway and a data server through a local network, the Internet gateway is connected with a cloud server, the PC client side is connected into the local network, the CMOS camera module is connected with a PLC, and the PLC is connected with a DCS. According to the novel intelligent liquid level measuring instrument, the inherent defects of poor reliability, low precision, no visibility, poor networking capability and the like when the liquid level is measured through traditional physical technologies such as ultrasound are overcome; the inherent defects that system adopting a PC technology to measure the liquid level islarge, complex, poor in realtime performance, low in integration degree, large in mounting difficulty, low in economic efficiency, low in reliability and the like can be overcome; and in addition, thenovel intelligent liquid level measuring instrument adopts system architecture design based on IP protocol, the configuration, management, data storage and historical reference modes of a traditionalliquid level measuring instrument are overturned, and the novel management and configuration mode conforming to IT characteristics are added.
