Abstract

The invention discloses a mining intelligent control switch based on the Internet of Things technology. The switch comprises a data acquisition unit and a soft start-stop unit, the comprehensive working condition of the intelligent control switch is analyzed according to various acquired data by arranging the data acquisition unit and a data analysis unit, the acquired data are compared with limited data or a threshold value to determine whether the state of each index is normal, and a control unit is used for corresponding processing, thereby enabling a monitoring platform to master the working state of the intelligent switch circuit in real time, improving the safety factor, reducing the labor intensity of a worker, and saving the cost. The soft start-stop unit is arranged to control conduction of a three-phase silicon controlled rectifier module, and the output voltage is limited by utilizing the change of the conduction angle of the three-phase silicon controlled rectifier, so that the damage caused by repeated contact of switch contacts is avoided, the service life of the intelligent control switch is prolonged, the soft start and stop of the control switch are realized, sparks are prevented from being generated in the on-off process of the switch, and the safety is improved.

Description

technical field [0001] The invention relates to a control switch, in particular to a mining intelligent control switch based on Internet of Things technology. Background technique [0002] As the start-stop control part of the terminal equipment, the control switch has a wide range of applications. The most commonly used control switch (also known as mine electromagnetic vacuum starter) is mainly composed of isolation reversing switch, vacuum contactor, comprehensive protector, button and other components. [0003] Ordinary control switches have the characteristics of complex structure, large amount of maintenance, poor reliability, and uncontrollable operating status, and the control switches are generally located at the end of the mine. The current control methods of manual control, manual inspection and maintenance are gradually unable to meet the requirements. The production needs of the mine, and the existing control switch cannot realize soft start and stop, and the s...
