Abstract

The invention discloses a multiple-serial-port bus system based on AT91M40800, which includes a micro-controller unit, an Ethernet interface unit, a CANBUS interface, a RS-485 interface unit, and an infrared remote interface unit. The Ethernet interface unit and CANBUS interface unit are connected with the micro-controller unit through a parallel bus, the RS-485 interface unit connected with the micro-controller unit through a serial bus, and the infrared remote interface unit connected with the micro-controller unit through parallel I / O interface. A third-party device is connected with the current inspection and monitor network through the multi-port system, which keeps clear of varied site networks of network interface type and protocol type, thus effectively solving the difficulty that the third-party device can not find access to the present network due to undisclosed techniques, and also the problems of the maintenance, upgrading, supplementation, and selection of inspection and monitor system in coal mines. The invention can avoid repeated purchase of system and equipment, lower investment and repair expense, and improve inspection and monitor system in coal mines. Therefore, the invention is particularly suitable for network connection equipment of inspection and monitor system in coal mines.

Description

technical field [0001] The invention relates to a network connection device of a coal mine underground monitoring and monitoring system, in particular to a multi-serial port bus system based on AT91M40800, which can enhance the network compatibility of the monitoring and monitoring system. technical background [0002] With the popularization and application of coal mine monitoring and monitoring systems, the efficiency and level of mine safety production management have been greatly improved. However, due to the non-uniform technical standards of coal mine monitoring and monitoring systems and the variety of communication interfaces and protocols, the communication between systems and equipment of domestic and foreign manufacturers cannot be achieved. compatible phenomenon. It is the method adopted by most manufacturers to expand the compatibility of the network as much as possible through the intelligent substation or to improve the intelligent substation and third-party e...
