Abstract

A remote operation and control system for a pressure filter; a PLC controller in a pressure filter body is connected to the interface of a GPRS-DTU communication network; the aerial of the GPRS-DTU communication network is linked to a communication tower via a signal; the communication tower is connected to a GGSN communication interface and an SGSN communication interface, forming a GPRS communication network; the GPRS communication network is connected to the wiring port of a router; a wire connects to a firewall via the router, and enters the wiring port of a switch; an industrial Ethernet is configured to connect to the wiring port of the switch. 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.

Claims

1. A remote operation and control system, comprising:

a pressure filter for solid-liquid separation and filtering materials containing a caustic chemical gas;

a general packet radio service-data transfer unit (GPRS-DTU) communication network provided in the pressure filter;

a Programmable Logic Controller (PLC) controller provided in the pressure filter and connected to the GPRS-DTU communication network;

a signal antenna provided for the GPRS-DTU communication network, wherein the antenna communicates with a communication tower;

a gateway GPRS support node (GGSN) communication interface and a serving GPRS support node (SGSN) communication interface, which form a GPRS communication network, wherein a signal from the communication tower is transmitted to the GPRS communication network and the GPRS communication network utilizes GPRS Access Point Name (APN);

a router connected to the GPRS communication network, wherein the signal is transmitted from a connection port of the GPRS communication network to the router;

a firewall connected to the router and a switch connected to the firewall, wherein the signal is transmitted to the firewall via the router and then to the switch;

a data center server receiving data contained in the signal from the firewall and sending instructions for controlling the PLC controller;

an industrial Ethernet connected to the switch, wherein a computer in the industrial Ethernet is connected to the switch and a PLC control system, and the computer receives the data from the data center server and provides a human-machine interface for monitoring the PLC controller; and

a fiber transceiver connected to the switch and the PLC control system.

2. The remote operation and control system for the pressure filter according to claim 1, wherein the computer in the industrial Ethernet comprises a workstation for an operator of the pressure filter.

3. The remote operation and control system for the pressure filter according to claim 1, wherein the computer in the industrial Ethernet comprises a workstation for an engineer of the pressure filter.

4. The remote operation and control system for the pressure filter according to claim 1, wherein the industrial Ethernet comprises an uninterruptible power system (UPS) power supply.

5. The remote operation and control system for the pressure filter according to claim 1, wherein the industrial Ethernet comprises a printer.

6. The remote operation and control system for the pressure filter according to claim 1, wherein the fiber transceiver is connected to the switch to form a Local Area Network for a company.
