Device for monitoring operation speed of power line type fieldbus belt conveyor

Abstract

The invention discloses a device for monitoring an operation speed of a power line type fieldbus belt conveyor, comprising a belt conveyor operation speed detection and treatment device and a dynamic power-supply system connected with the belt conveyor operation speed detection and treatment device, wherein the belt conveyor operation speed detection and treatment device comprises a sensor detection unit and an electric cabinet matched with the sensor detection unit; the electric cabinet comprises a control cabinet body, a signal conditioning circuit connected with the sensor detection unit, a microprogrammed control unit (MCU) processor and an input / output (I / O) communication interface connected with the MCU processor; the sensor detection unit comprises a tape speed sensor and / or rotate speed sensor; and the MCU processor is connected with a main programmable logic controller (PLC) control system through the I / O communication interface and a cable. The device is simple in structure, small in volume and convenient for installation, signal transmission is stable, intelligent level is high, operation and maintenance work load is less; and by using the device, the problems, existing in the current belt conveyor operation speed monitoring device in a thermal power plant, such as fussy wiring, far cable distance, extremely difficult construction and the like, are solved.

Description

technical field [0001] The invention belongs to the technical field of belt conveyor running speed monitoring, in particular to a power line type field bus belt conveyor running speed monitoring device. Background technique [0002] At present, there are a large number of belt conveyors in the coal transportation system of thermal power plants. Therefore, when monitoring the working status of each belt conveyor, especially when monitoring the running speed, there are a lot of data to be monitored and the detection process is cumbersome. The traditional monitoring and control method of monitoring and controlling the running speed of the belt conveyor and the monitoring device used in conjunction with it generally have a large amount of cables, cumbersome wiring, long preset cable distances, high one-time investment costs, and long construction periods. There are many practical problems such as long construction time, difficulty in on-site construction, difficulty in system op...
