Mining flame-proof and intrinsic safety type monitoring substation

Abstract

The invention discloses a mining flame-proof and intrinsic safety type monitoring substation which comprises a main shell and an intrinsic safety shell, one side of the main shell is fixedly connected with the intrinsic safety shell, the main shell comprises a panel, hinges and hexagon socket cap screws, the panel is arranged on one side of the main shell, the panel is connected to the main shell through the two hinges, and the panel is connected with the intrinsic safety shell through the two hinges. And a plurality of hexagon socket cap screws penetrate through the panel and are connected with the main shell. According to the intrinsic safety type monitoring substation, input and output holes are increased, communication interfaces are rich, many other devices can be connected, application scenes are rich, an installed displayer adopts a 10.1-inch high-definition color screen, display is clearer, operation is more convenient, the transmission distance of the device is long, the maximum transmission distance from the substation to a sensor is not smaller than 2 km, and the device is convenient to use. The maximum transmission distance between the substation and the control actuator is not less than 2km, the maximum transmission distance between the substation and the transmission interface is not less than 10km, and the maximum transmission distance between the substation and the mining network switch adopting an RS485 transmission mode is not less than 5km.

Description

technical field [0001] The invention relates to the technical field of mine explosion-proof monitoring, in particular to a mine explosion-proof and intrinsically safe monitoring substation. Background technique [0002] Mine flameproof and intrinsically safe monitoring substation (hereinafter referred to as substation) is an embedded control device with a 32-bit embedded microcontroller based on ARM core as the core. Various environmental parameters such as gas, wind speed, carbon monoxide, negative pressure, equipment start and stop status and other lower-level intelligent equipment are continuously monitored, with multi-channel and multi-standard signal acquisition and communication functions Various environmental parameters and equipment status are transmitted to the ground central station, and various commands issued by the central station are executed, and alarms and power-off control signals are issued in time. [0003] The explosion-proof and intrinsically safe monit...

Problems solved by technology

[0006] Aiming at the deficiencies of the existing technology, the present invention provides a mining explosion-proof and intrinsically safe monitoring substation, which solves the problem that the existing input and output holes are too few, and there are too few communication interfaces, and there are few other devices that can be connected, so rich scenarios cannot be applied. ;The current monitoring sub-station has no screen, cannot display the usage status, and the operation is complicated; when the device is far away, the transmission rate information cannot be received
