Abstract

The invention relates to a heading machine control and protection technology and especially relates to a heading machine control and protection device. By using a current heading machine control and protection technology, reliability of the control and protection is poor. By using the device of the invention, the above problem is solved. The heading machine control and protection device comprises a digital quantity input plate, a digital quantity output plate, an analog quantity input plate, a DSP control panel, a first power plate, a second power plate and a mother board. The mother board comprises a power supply bus and a CAN bus. A power supply input terminal of the digital quantity input plate, a power supply input terminal of the digital quantity output plate, a power supply input terminal of the analog quantity input plate, a power supply input terminal of the DSP control panel and a power supply output terminal of the first power plate are connected with the power supply bus. A signal transmission terminal of the digital quantity input plate, a signal transmission terminal of the digital quantity output plate, a signal transmission terminal of the analog quantity input plate and a signal transmission terminal of the DSP control panel are connected with the CAN bus. The device of the invention is suitable for the control and protection of the heading machine.

Description

technical field [0001] The invention relates to a roadheader control and protection technology, in particular to a roadheader control and protection device. Background technique [0002] The roadheader is an important equipment for underground operations in coal mines. During the operation of the roadheader, it is necessary to control and protect the various components of the roadheader to ensure the normal operation of the roadheader, thereby ensuring the safe and efficient production of the coal mine. Under the existing technical conditions, the control and protection of the roadheader are mainly realized through the PLC control and protection system. PLC control and protection system mainly includes PLC controller and a large number of modulus protection modules. When the PLC control and protection system is used to control and protect the roadheader, each quantity that needs to be controlled and protected is first converted into a switch digital quantity through the mo...
