Embodiment Construction

[0012] refer to figure 1 , the present invention is mainly made up of embedded micro-controller U1, storage chips U2, U3, U5, network module U9, fieldbus protocol conversion modules U7, U8 and AD module U6, etc., using an embedded real-time operating system. To realize the conversion of bus protocol and Ethernet signal, the integrated access gateway can collect various sensors (analog quantity), controller (switch quantity), RS485 / CAN bus signal and other system data, and then carry out the agreement through the core control board convert.

[0013] Such as figure 2 As shown, among them, U1: Embedded microcontroller, which is the core part of the circuit, mainly implements the conversion of the data received by the peripheral modules into Ethernet signals suitable for network transmission through the internal software protocol conversion part or converts Ethernet signals into other protocol signals.

[0014] U2, U3, U5: U2 is SDRAM memory chip, adopts HY57V641620 type, and ...

Abstract

The invention relates to a mine-used safety integrated access gateway, which comprises an embedded processor, an embedded real-time operating system and software technique, to realize the access function of variable substations and the linkage between variable detecting systems, to complete the protocol transformation of industrial Ethernet used in mine, while it can directly be connected to the under-mine safety detecting sensor. The invention, via industrial Ethernet or the optical fiber, collects the on-site data to the mine main communication network. The inventive gateway can be used in the message transfer and transmission under the mine and the ground detection distribution.

Description

technical field [0001] The present invention relates to a mining monitoring and monitoring system, specifically a mining explosion-proof and intrinsically safe integrated access gateway, and further a device that converts various field bus information data into Ethernet signals through protocols , convenient for mine industrial Ethernet or optical fiber transmission, especially suitable for use in the dangerous, flammable and explosive environment of underground coal mines with a lot of gas and coal dust. Background technique [0002] At present, there are many types of underground safety production monitoring and monitoring systems in my country. Most of the monitoring and monitoring systems used were developed before the 1990s. They are mainly based on 8 / 16-bit single-chip microcomputers and serial data links, and the communication rate is low. Various monitoring systems and control systems are independent systems, incompatible with each ot...
