Coal cutter shutdown control system based on USB flash disk authentication

Abstract

The invention relates to a coal mining machine shutdown control system based on USB flash disk authentication, which comprises a unique authentication USB flash disk which is internally provided with authentication information and cannot be copied, and a USB flash disk reading device, an authentication judgment device and a coal mining machine shutdown control device which are in communication connection in sequence, a USB flash disk interface unit is arranged in the USB flash disk reading device, the authentication USB flash disk is connected and communicated with the USB flash disk reading device through the USB flash disk interface unit, and after the coal mining machine system is powered on, the USB flash disk reading device reads authentication information from the authentication USB flash disk and transmits the authentication information to the authentication judgment device; the authentication and judgment device compares the unique machine identification code of the coal mining machine according to the read authentication information, judges whether the USB flash disk is an effective authentication USB flash disk or not, sends a judgment result to the coal mining machine shutdown control device, and controls to turn off the power supply of the whole coal mining machine when the judgment result is invalid. According to the invention, the coal mining machine can be controlled to be continuously started or stopped at proper time after the identity of a starting person is identified.

Description

technical field [0001] The invention relates to a coal shearer shutdown control system, in particular to a system for coal shearer shutdown control through U disk authentication. Background technique [0002] The shearer is a large electromechanical device, and its opening must follow the relevant safety procedures. The existing management methods of shearer startup are mainly through mechanical locks and password locks. Specifically, before the startup of the shearer, someone who has the relevant key or password will open the starter button cover or isolating switch wrench of the shearer, and then start coal mining. machine. There are also ways to turn on the shearer through iris recognition, inputting the power-on password, etc. The characteristics of these methods are that the people with power-on authority are relatively fixed, so they are more suitable for the management of shearers within the coal mine. [0003] However, more and more coal machines now belong to min...

Problems solved by technology

[0003] However, more and more coal machines now belong to mining groups or coal machine leasing companies, and coal machines often need to be transferred between different coal mines. The above-mentioned traditional start-up management method cannot adapt to this situation well, and there are many disadvantages

For example, regarding the mechanical lock method, the key is easy to be copied. At the same time, the key has a variety of styles, which is easy to be confused with other keys and is inconvenient to manage. Regarding the password lock method, the password needs to be passed on by word of mouth, and it is easy to spread when there are many people in contact. Decrease; Regarding the iris method, it is limited to specific personnel. Once the personnel is temporarily busy, it will cause the shearer to fail to start

In addition, all the above-mentioned methods are restricted before starting the coal mining machine, and can be used normally after starting up, and cannot realize the function of starting up for a trial run for a period of time and then shutting down
