An industrial multi-parameter data remote transmission device

Abstract

The invention discloses an industrial multiple-parameter data remote transmission device which comprises a PLC, an industrial data collector, a transformer, an uninterruptible power supply (UPS), a wireless data remote transmission unit DTU and a touch screen, wherein the PLC is connected with the wireless data remote transmission unit DTU, the industrial data collector and the touch screen; the transformer and the UPS are connected with the PLC, the industrial data collector, the wireless data remote transmission unit DTU and the touch screen respectively. With the adoption of the industrial multiple-parameter data remote transmission device, collection, remote transmission and intelligent monitoring of a monitoring device on field data can be realized, a developable intelligent control platform is realized, working personnel can perform visual monitoring conveniently on the field condition of the overall area in one monitoring center; besides, the VPN technology is adopted for remote transmission, and undistorted bidirectional data transmission between the remote monitoring center and the monitoring spot is realized through the GPRS network and internet.

Description

technical field [0001] The invention relates to remote monitoring technology, in particular to an industrial multi-parameter data remote transmission device aimed at industrial site operating conditions. Background technique [0002] At present, most enterprises pay more attention to production automation. They either use DCS (including PLC) or use CP bus-based industrial computer to form a simple distributed measurement and control system. But in reality, the automation system is scattered on each device, and there is no means of interconnection among the automation devices in the enterprise, so it is difficult to realize real-time information sharing. Most of the current PLC control systems use the field control bus. The network based on this bus is closed and the openness is not good. The workstations need to be equipped with special communication cards to communicate with each other, and the cost is very high. Located at the field control layer, it cannot be uploaded to...
