Coal mine underground comprehensive data acquisition substation

Abstract

The present invention provides a coal mine comprehensive data collection substation, including a button module and an LCD display module for human-computer interaction; an RS485 driver module, a CAN driver module, a Zigbee module, an RFID module, a Wave Mesh module and an LCD display module for data communication. Ethernet module; open-in module and open-out module for connecting sub-equipment of coal mine underground application system; embedded system microprocessor for data processing and control of other modules and power supply module for providing working power; The embedded system microprocessor built-in embedded operating system platform realizes the integration of the functions of the existing coal mine underground systems. The invention can greatly reduce the number of underground coal mine substations, reduce the complexity of installation and wiring, reduce the workload of maintenance personnel and coal mine construction and operation costs, and truly realize "one network and one station" for coal mine underground data collection.

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.
