Comprehensive data acquisition substation for underground coal mine

Abstract

The invention provides a comprehensive data acquisition substation for an underground coal mine. The comprehensive data acquisition substation includes: a button module and an LCD display module for man-machine interaction; RS485 drive modules for data communication, CAN drive modules, a Zigbee module, an RFID module, a Wave Mesh module and Ethernet modules; a switch-in module and a switch-off module for being connected to an application system subset in an underground coal mine; an embedded system microprocessor for data processing and control for other modules; and a power supply module for providing a work power supply. The embedded system microprocessor is equipped with a built-in embedded operation system platform so that all application system functions for a current underground coal mine are combined as a whole function. The number of substations in the underground coal mine is greatly reduced, the complexity of mounting wiring is minimized, the workload for maintenance workers is reduced, the coal mine construction and operation costs are cut, and data acquisition in the underground coal mine can be truly achieved by one network and one station.

Description

technical field [0001] The invention relates to the technical field of coal mine communication equipment, in particular to an underground coal mine comprehensive data collection substation. Background technique [0002] At present, there are many types of application systems in use in coal mines, including comprehensive coal mine monitoring system, mine roof pressure monitoring system, rubber-tyred vehicle transportation monitoring system, mine rail transportation monitoring system, mine logistics management system and mine multimedia comprehensive information release system, etc. etc., there may be multiple types of substations in each system. Substations in each system, even if they use the same signal transmission method, cannot use the same hardware to connect to the network due to differences in transmission protocols. This makes it possible that there are multiple substations of multiple systems at the same installation site underground in the coal mine, and each subs...

Problems solved by technology

Substations in each system, even if they use the same signal transmission method, cannot use the same hardware to connect to the network due to differences in transmission protocols

This makes it possible that there are multiple substations of multiple systems at the same installation site underground in the coal mine, and each substation has at least one communication interface connected to its sub-equipment through a cable, and a cable (or transmission line such as an optical cable) directly or indirectly connected to the Ground computer, resulting in low utilization rate of substation resources, repeated laying of cables, resource redundancy and waste

The status quo of multiple systems, multiple substations, and multiple cables not only causes a waste of resources such as substation equipment and transmission cables in the coal mine underground system, but also increases the disorder of the multi-system topology and the complexity of the installation process, which poses a threat to the staff The maintenance work brings great difficulties and duplication of labor

[0003] In response to the above problems, in recent years, the coal mine system has proposed a new concept of "one network and one station" for underground data collection sub-stations. In the shell, it is essentially just a simple pile of substations of various application systems in the mine. The hardware resources of different substations in the "one station" are not shared. Although this kind of underground data acquisition substation can be used to a certain extent It reduces the complexity of underground system connection, but still does not fundamentally solve the problem, and cannot meet the business needs of users in flexible addition, deletion, and improvement of application systems.
