Laboratory rack management control server

Abstract

The invention relates to a laboratory rack management control server which comprises a casing, and a mainboard and a power supply module which are arranged in the casing. The mainboard is provided with a CPU module, and a storage module, an RS232 interface module, a wireless communication module, a USB interface, a plurality of internet access transformers and a plurality of parallel port-to-serial port modules which are electrically connected with the CPU module. The RS232 interface module is connected with a serial port interface, each internet access transformer is correspondingly connectedwith an Ethernet interface, each parallel port-to-serial port module is respectively connected with a plurality of parallel port-to-serial port interfaces, and the power supply module supplies powerto the modules on the mainboard. The server is large in number of serial ports and rich in interfaces, has a wireless communication function, can manage and control a plurality of network devices, andis flexible in field installation and application.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a laboratory rack management control server. Background technique [0002] The laboratory rack management control server is a communication device that provides serial port to network function, which can convert RS-232 / 485 / 422 serial port into TCP / IP network interface, and realize RS-232 / 485 / 422 serial port and TCP / IP The data of the IP network interface is bidirectionally transparently transmitted, so that the serial device can immediately have the function of the TCP / IP network interface, connect to the network for data communication and effectively extend the communication distance of the serial device. Serial servers are widely used in many fields such as access control systems, attendance systems, vending systems, POS systems, building automation systems, self-service banking systems, telecommunications room monitoring, and power monitoring. At present, in serial commu...

AI Technical Summary

Problems solved by technology

At present, in serial communication technology, serial devices and network devices are often used synchronously, but the current serial servers have fewer serial ports, which need to be realized by connecting multiple external switches, which not only increases the cost, but also is inconvenient for multiple network devices on site. manage

In addition, the interface is not rich enough, the serial port circuit is inconvenient to use, and the interface forms of different serial devices in different industrial sites are not considered.

In addition, the current common serial servers do not have wireless communication functions, so they can only be used in places covered by wired networks, which greatly limits their applications.
