Portable emergency communication system with multiple service interfaces

Abstract

The invention discloses a portable emergency communication system with multiple service interfaces, which can realize the purposes of flexible service configuration, flexible and convenient interfacesand communication after plugging. The system comprises an MPU main control module (101), an EML16 E1 interface module (102), an FE8 Ethernet module (103), a PCM voice module (104) and an AC / DC unit (105). SDH / MSTP and IP full-digital processing technologies are adopted; wherein the MPU main control module (101) is connected with the EML16 E1 interface module (102), the FE8 Ethernet module (103) and the PCM voice module (104) through an SERDES bus; and the AC / DC unit (105) supplies power to the MPU main control module (101), the EML16 E1 interface module (102), the FE8 Ethernet module (103) and the PCM voice module (104).

Description

technical field [0001] The invention belongs to the technical field of communication, in particular to an emergency communication system with a portable multi-service interface. Background technique [0002] At present, various professional business systems along the railway line, such as microcomputer monitoring, CTC, passenger ticket, traction telecontrol, electric power telecontrol and other business channel communication systems, use wired communication to support the network and use SDH / MSTP technology equipment networking, although in infrastructure The project provides an emergency communication system, but it cannot meet the needs of the railway communication maintenance department in dealing with emergency communication scenarios. [0003] Sudden emergency failures in railway communication transmission equipment, data equipment, access equipment, and power supply equipment, such as: software and hardware failures in main boards such as equipment power boards and cro...
