Remote wireless monitoring method for thickener

Abstract

The invention discloses a remote wireless monitoring method for a thickener. The method is applied to that a DCS (distributed control system) system or a PLC (programmable logic controller) system performs remote wireless monitoring on the thickener. The wireless monitoring method comprises the following steps of: erecting an outdoor antenna and installing a feed line nearby a remote controller and a thickener controller at first; then respectively installing data transfer radios on the thickener controller and the remote controller; connecting the data transfer radios and the antenna via the feed line, and setting parameters of the data transfer radios; and according to different communication interfaces and different communication protocols of the remote controller, finally setting interface parameters on a DCS controller or a PLC, the data transfer radios and the thickener controller, and writing programs and setting communication areas in the controllers to enable the DCS controller or the PLC controller to perform data exchange with one or more thickener controllers, thus realizing the remote monitoring on the thickener. Via the remote wireless monitoring method for the thickener, disclosed by the invention, the problem of remote monitoring on the thickener in the case that the wiring can not be realized is solved.

Description

technical field [0001] The invention is applied to the remote wireless monitoring of the thickener by a DCS or PLC system. Background technique [0002] As the main equipment for thickening pulp, thickener is widely used in mineral processing industry. The purpose of the thickener in the production process is to provide pulp with a qualified concentration for the subsequent process to ensure that the flow rate of the pulp meets the production demand. Due to its complex process, harsh operating environment, and frequent changes in the nature of the incoming materials from the superior process, in order to effectively operate the equipment and improve the process accuracy, the automatic control system has gradually replaced the on-site manual operation on the medium and large thickeners. Mainstream control method. The application of the automatic control system in the thickener not only improves the process characteristics of the system, but also can become a part of the PCS...

Problems solved by technology

However, due to the unique structure and working method of the thickener, especially for the thickener with the surrounding transmission structure, the on-site controller of the equipment is often installed on the walking bridge. Although this setting method is convenient for direct control of the equipment on the bridge, However, since the bridge frame will rotate clockwise around the center of the thickener when the thickener is running, it is very difficult to directly connect the thickener to the remote control equipment.

In order to meet the needs of remote equipment to receive the status information of the thickener and control the operation of the thickener, a new control method is needed to solve the industrial production requirements of the large data volume control of the thickener that cannot be met by the traditional wiring method
