Distribution frame with intelligent port scanning device and distribution system

Abstract

The embodiment of the invention discloses a distribution frame with an intelligent port scanning device and a distribution system. In the distribution frame with the intelligent port scanning device, the scanning device comprises a field programmable gate array (FPGA), a monitoring port, an RS232 level conversion circuit group and a network module group, wherein the FPGA includes a universal asynchronous receiver / transmitter (UART) and an expanded UART; each port of the expanded UART is respectively connected with each RS232 level conversion circuit of the RS232 level conversion circuit group; each RS232 level conversion circuit is respectively connected with each corresponding network module of the network module group one by one; and the UART is connected with the monitoring port. The embodiment of the invention can achieve the concurrent scanning of the distribution frame during concurrently scanning the port of each network module of the distribution frame by transmitting the jumper connection information of each network module of the distribution frame to the FPGA, thereby improving the port scanning efficiency.

Description

technical field [0001] The invention relates to the field of intelligent management of wiring systems, and more specifically relates to a distribution frame and a wiring system with an intelligent port scanning device. Background technique [0002] With the continuous development and progress of the intelligent management of the wiring system, the electronic distribution frame has been more and more widely used. [0003] At present, commonly used electronic distribution frames usually use a port detection method or a link detection method to scan the ports of switches. Among them, the principle of the link detection method is to add one or two wires to the ordinary jumper. This kind of jumper is generally called a 9-core or 10-core jumper. The electronic distribution frame based on the link detection method uses the extra wires to determine the connection status of the port. When this 9-core or 10-core jumper is connected to two ports, the system will detect the link relat...

Problems solved by technology

[0004] In the electronic distribution frame system of the link detection method, the link relationship is obtained by scanning the link. In the prior art, the scanning link is carried out by port-by-port scanning, and its disadvantage is that the scanning speed is slow , when the number of ports in the distribution frame system is large, the scanning time is too long, which affects work efficiency
