REMOTE OPERATION AND CONTROL SYSTEM FOR PRESSURE FILTER

摘要

A remote operation and control system for a pressure filter; a PLC controller (2) in a pressure filter (1) body is connected to the interface of a GPRS-DTU communication network (3); the aerial (4) of the GPRS-DTU communication network (3) is linked to a communication tower (5) via a signal; the communication tower (5) is connected to a GGSN communication interface (6) and an SGSN communication interface (7), forming a GPRS communication network; the GPRS communication network is connected to the wiring port of a router (8); a wire connects to a firewall (9) via the router (8), and enters the wiring port of a switch (10); an industrial Ethernet (11) is configured to connect to the wiring port of the switch (10). The remote operation and control system for a pressure filter achieves unattended operation on the working site of the pressure filter, thus improving the technical level of the control system.
