Talkback and warning voice broadcast system suitable for overhaul train operation vehicle

Abstract

The invention provides a talkback and warning voice broadcast system suitable for an overhaul train operation vehicle, and belongs to the technical field of rail transit communication. The system mainly comprises a multi-party voice talkback and automatic warning voice broadcast function, and is used for meeting the requirements of multi-party voice intercom of platform personnel, driver personneland command room personnel of the maintenance train operation vehicle and voice coverage of all operation platforms, personnel on the operation platforms can conveniently answer operation instructions sent by personnel in the vehicle in real time, and the purposes of instant communication and rapid communication can be achieved. The system has the advantages of low operation cost, no call chargeconsumption and the like, and the reliability, stability, safety and intelligent level of the system are improved. Moreover, an automatic warning voice broadcasting function and a talkback function are integrated into a structure, the integrated structure design is more convenient to install and fix, shunt processing is carried out on signals of the two functions, when one path of signals breaks down, work of the other path of signals cannot be affected, and the integration degree is high.

Description

technical field [0001] The invention belongs to the technical field of rail transit communication, and in particular relates to an intercom and warning voice broadcast system suitable for maintenance train operation vehicles. Background technique [0002] In recent years, my country's railways have achieved leapfrog development. By 2020, the operating mileage of national railways will reach 120,000 kilometers. The rapid development has also put forward higher requirements for the operation safety of railway power supply equipment. The good condition of electrified railway catenary is the basis for railway safety and high-speed operation. Therefore, higher requirements have been put forward for the quality of track equipment maintenance. The railway maintenance train is the main vehicle to ensure the maintenance of track equipment. However, the existing maintenance trains are difficult to meet the high-speed, high-efficiency and high-reliability maintenance requirements under ...

AI Technical Summary

Problems solved by technology

The railway maintenance train is the main vehicle to ensure the maintenance of track equipment. However, the existing maintenance trains are difficult to adapt to the high-speed, high-efficiency and high-reliability maintenance requirements under the new situation. The maintenance trains are generally longer, including The driver's cab, command vehicle and multiple work vehicles are not connected to each other. There is no voice broadcast warning system connected to each other. Get reminded in time, which will affect the implementation of maintenance instructions and reduce work efficiency
