WE-KT700 helps mining explosion-proof switch remote networking monitoring

I: Overview note

       In recent years, China's rapid economic development, and mine development as one of the main lifeblood of global economic development, more economic development provides most of the energy and industrial raw materials. Mining mobile substation is responsible for the entire mine power transmission and distribution of the core equipment, determines the source of all the equipment under the mine with electricity, underground electricity safety is a major event related to the safety of mine workers' lives, and thus as a mining mobile substation on the safety control of electricity explosion-proof high and low voltage switches is particularly important, its performance directly affects and determines the entire coal mine safety accident probability of high and low, is the various mine It is an important mining equipment that every coal mine should carefully choose and buy.

II: Industry status and needs

        With the development of industrial automation and IoT application technology, mining is also toward unattended, industrial robots instead of traditional mine workers, remote large screen monitoring and other direction of the development of intelligent mining mining. Intelligent mining technology will bring unprecedented opportunities to the development of the world's mining industry, the traditional mining technology will gradually exit the stage, intelligent, informationized, automated mining technology is about to open a new and dynamic field of scientific and technological development. 2021, the National Energy Group and Huawei jointly released the mine Hong operating system is for China's intelligent mining mining to provide systematic support, perhaps the near future. In the near future, moving a finger to mine coal is no longer a dream.

        Although Huawei's mine system formulates unified data standard (HCP) protocols, builds an industrial Internet ecosystem, effectively breaks down the "data barriers" and "information chimneys" of coal mining enterprises, and realizes data fusion, sharing, and intelligent applications, creating a solid cornerstone for the intelligent construction of coal mines, it also requires electrical and mechanical control equipment in the mines to have network communication capabilities. Construction to create a solid cornerstone, but also need to mine under the power and mechanical control equipment have the ability to network communication access, and traditional such as mining explosion-proof switches and other power protection equipment are only commonly used in industrial communication RS485 communication interface, can not be connected to the cloud server side of the mine Hong system communication, the development of this smart mine and the promotion of the mine Hong has brought obstacles and limitations, the Hainan Shidian and a large mining equipment manufacturers to communicate and understand the After communicating with a large mining equipment manufacturers to understand the pain points and problems they encountered, for the mining shift switch in the mine under the industry networking application needs, successfully developed a RS485 to Ethernet / fiber / WiFi multi-function networking converter WE-KT700, so that the traditional shift switch instantly has a network interface communication capabilities, to facilitate the monitoring parameters of the mining shift switch access to the mine Hong and other smart Mining monitoring platform.

III: Product Introduction & Application Methods

WE-KT700 is an industrial-grade serial RS485 network converter, can simultaneously support the realization of wired Ethernet; fiber optic and wireless WiFi three communication modes, you can quickly achieve the traditional serial device networking function through plug-and-play.

• Support Ethernet; WiFi; fiber optic three network communication methods
• Supports both AP and STA modes
• Supports 2 RS485 ports, serial rate up to 460800bps
• Supports multiple working modes: network pass-through mode; Modbus RTU to Modbus TCP Modbus TCP to Modbus TCP to Modbus RTU

• Supports WiFi communication with the accompanying mobile app (Modbus TCP)
• Support serial port, network OTA firmware upgrade
• Supports hardware Reset to restore factory values with one key.
• Supports industrial grade operating temperature -40~+85
• Supports wide power supply 5~36V
• Strict industrial reliability design, can resist 10KV arc interference
• Stable and reliable FC fiber optic interface, single mode fiber up to 20km long

        By adding an RS485 3-in-1 converter WE-KT700 to each mine explosion-proof high-explosive switch, the traditional explosion-proof switches become intelligent high-explosive switches with network communication capability, and the two are connected through the RS485 interface, and the monitoring parameters of the high-explosive switches can be transmitted to the well by borrowing any of the Ethernet/fiber-optic/WiFi interfaces of WE-KT700. Application server platform software, timely control of underground electricity status and safety, the application of the entire system topography is shown below:
