Embodiment 1

[0022] Such as figure 1 As shown, the present embodiment provides a conveyor belt tear-resistant monitoring system, including STC12C5A60S2 single-chip microcomputer, storage unit, KB1-40 current-voltage converter, HK4100 relay, motor power supply unit, motor and voice alarm, STC12C5A60S2 single-chip microcomputer and storage Unit, KB1-40 current-voltage converter, HK4100 relay and voice alarm signal connection, KB1-40 current-voltage converter is electrically connected to the motor power supply unit, HK4100 relay is connected to the motor signal, and the motor is connected to the conveyor belt power. Specifically, the first pin P1.0 / T2 of the STC12C5A60S2 single-chip microcomputer is connected to the motor power supply unit through the KB1-40 current-voltage converter, the second pin P3.6 / WR of the STC12C5A60S2 single-chip microcomputer is connected to the motor through the HK4100 relay, and the first pin of the STC12C5A60S2 single-chip microcomputer The three-pin P4.0 is conn...

Embodiment 2

[0024] The difference between this embodiment and Embodiment 1 is that the conveyor belt tear prevention monitoring system also includes a flashing light, which is connected to the signal of the STC12C5A60S2 single-chip microcomputer. During the normal operation of the conveyor belt, the flashing light is off or always on. When the single-chip microcomputer controls the motor to stop working through the HK4100 relay, the flashing light keeps flashing to visually notify the operator.

Embodiment 3

[0026] The difference between this embodiment and Embodiment 1 is that the conveyor belt anti-tear monitoring system also includes a display screen, which is connected to the signal of the STC12C5A60S2 single-chip microcomputer, and the display screen is used to display the operating status of the conveyor belt anti-tear monitoring system for convenience. Operators operate, inspect and maintain. The STC12C5A60S2 MCU detects that the current fluctuation of the motor power supply unit in the working mode exceeds the data of the current fluctuation of the motor power supply unit recorded in the learning mode. When the STC12C5A60S2 MCU controls the motor to stop working through the HK4100 relay, the STC12C5A60S2 MCU sends a signal to the display screen. The signal is transmitted to the computer, and the operator observes the display screen to confirm the operation data information of the conveyor belt tear prevention monitoring system.

Abstract

The invention discloses an anti-tearing monitoring system for a conveying belt. The anti-tearing monitoring system comprises a single-chip microcomputer, a storage unit, a current and voltage conversion unit, a relay, a motor power supply unit and a motor. The single-chip microcomputer is in signal connection with the storage unit, the current and voltage conversion unit and the relay. The current and voltage conversion unit is electrically connected with the motor power supply unit. The relay is in signal connection with a motor. The motor is in power connection with a conveying belt. The anti-tearing monitoring system has the beneficial effects that physical hardware of an original conveying belt does not need to be greatly modified, so that the input cost is relatively low; longitudinal tearing of the conveying belt is prevented by monitoring the current fluctuation condition of the motor power supply unit, and the motor can stop working in time so as to prevent the conveying belt from being torn longitudinally.

Description

technical field [0001] The invention relates to the technical field of conveyor belt control, in particular to a conveyor belt tear prevention monitoring system. Background technique [0002] In industrial production activities, belt conveyors are commonly used industrial equipment. The conveyor belt is an important part of the belt conveyor, and the cost of the conveyor belt accounts for 30%-50% of the cost of the whole machine. However, longitudinal tearing accidents of conveyor belts occur from time to time, causing huge property losses to users. There are many reasons for the longitudinal tearing of the conveyor belt. Among them, the unstable running current of the conveyor leads to the abnormal movement of the conveyor belt and the longitudinal tearing of the conveyor belt is a reason with a high probability of occurrence. [0003] The Chinese patent document with the publication number CN105692120A discloses a conveyor belt longitudinal tear monitoring device and mon...
