Problems solved by technology

Since the Enet-B device is solidified into the Master mode, and the on-site BSC serial device protocol is often solidified into the Master mode, in use, due to the relatively large amount of communication data, a large number of frequent conflicts in the communication process may easily cause protocol conflicts so that the communication Interruption, cannot solve the communication problem between BSC serial device and Ethernet device in many enterprises

Embodiment Construction

[0025] The present invention is to realize the communication of Ethernet and BSC serial device in the field environment, an embodiment is as follows Figure 7 As shown, use Enet-B for physical link conversion, use the RS232 interface of the serial port cable to connect the BSC serial communication device and Enet-B, and use the twisted pair RJ45 interface to connect Enet-B and the Ethernet device application server (can be directly connected or through Switch), and set the transmission mode of Enet-B equipment to one-by-one conversion mode A, based on the TCP / IP protocol, develop the protocol communication module XCOM, analyze the state of the BSC protocol, perform state conversion, and realize the configuration of Master / Slave , the protocol communication module XCOM sets its own priority, and exchanges data with the application program of the Ethernet device through the application program database. A message configuration table and a message interface table are created in th...

Abstract

This invention disclose a system and method for Ethernet device communicating with BSC serial port device, using an Enet-B device to connect an Ethernet device and a BSC serial port device, further comprising a protocol communication module XCOM. The transmission mode of the Enet-B device is set as a gradually converting mode A; the protocol communication module XCOM is used for realizing the communication conversion of the serial port device and the Ethernet device via the Enet-B device. A TCPDUMP program is used for capturing a TCP / IP protocol and filtering a bottom layer answer signal; and the protocol communication module XCOM is informed by a UNIX signal so as to guarantee the synchronous transmission and avoiding the automatic packing of the TCP / IP protocol. This invention uses the Enet-B device to realize the communication between the Ethernet device and the serial port device, without the communication interruption caused by the collision protocol in the communication process.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a system and a method for communicating between an Ethernet device and a serial port device. Background technique [0002] Since the enterprise started the process of informatization at an early stage, it is inevitable that some network environments and system environments in different periods will be left behind. Since the data provided by different users may come from different ways, this even includes production control in non-network environments System, its data content, data format and data quality vary widely, and sometimes even encounter difficult problems such as data format cannot be converted or data is lost after format conversion. Therefore, in the process of implementing data integration, a severe test is put forward for the flow and sharing of data in each host system and each software system. [0003] Many early information systems in enterprise...
