Embodiment Construction

[0028] System composition:

[0029] (1) Microcontroller module U_1: composed of ARM7 processor LPC2214 produced by Philips, LPC2214 is based on a 16 / 32-bit ARM7TDMI-STMCPU microcontroller that supports real-time simulation and tracking, and has a 256kB embedded high-speed Flash memory. The 128-bit wide memory interface and unique acceleration structure enable 32-bit code to run at the maximum clock rate, and the maximum CPU operating frequency of 60MHz can be realized through the on-chip PLL. LPC2214 has a 144-pin package and provides 3 sets of 32-bit ports for use by peripheral equipment, meeting the interface requirements for A / D conversion and Ethernet communication of parallel processing of high-speed vibration signals. ARM7TDMI-S is a general-purpose 32-bit microprocessor with a port voltage of 3.3V and a core voltage of 1.8V. It has high performance and low power consumption, and can easily meet the intrinsically safe requirements of coal mines. The ARM architecture is...

Abstract

The invention relates to an embedded system based intrinsic safety type coal mining machine state monitoring and analyzing device. In the invention, a high-performance industrial grade ARM embedded processor and a system are used for forming a complete coal mining machine working condition signal monitoring, analyzing and processing system, and the device is designed on the basis of the general requirement GB3836.1-2000 of electrical equipment for explosive gas atmosphere and the intrinsic safety type requirement GB3836.4-2000 and mainly applied to monitoring and analyzing the working condition signals of an underground coal mining machine of a coal mine. The device comprises a microcontroller module (U_1), an RS232 serial communication module (U_2), a vibration signal and conventional analog quantity acquisition and analysis module (U_3), an Ethernet communication module (U_4), a power supply module (U_5), a data storage module (U_6) and a sensor module (U_7). The invention improves the state monitoring and fault diagnosing level of the coal mining machine; and by utilizing the system, the running condition and the working load condition of the coal mining machine can be monitored in real time on line, which provides reliable data for realizing the high-efficiency automatic mining, the remote operation and the fault diagnosis of the coal mining machine.

Description

technical field [0001] This device adopts a high-performance industrial-grade ARM embedded processor and system to form a complete monitoring, analysis and processing system for the working condition signal of the coal shearer. The device is based on the general requirements for electrical equipment used in explosive gas environments GB3836. And the design of intrinsically safe requirements GB3836.4-2000 is mainly used in the monitoring and analysis of working condition signals of coal mining machines in underground coal mines. Background technique [0002] At present, the state monitoring of the coal mining machine is to install a programmable logic controller (PLC) in its explosion-proof chamber, through which the conventional analog quantities (current, voltage, temperature, flow, pressure, traction speed, position, etc.) are monitored. Acquisition and simple logic overrun alarm, and then displayed on the display. Due to the speed limit of PLC execution instructions and ...
