Example Embodiment

[0016] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0017] The whole system is like figure 1 As shown, the scheme of the present invention is as follows: In a passenger train 110 alarm system, the entire communication system A is composed of a main station C and n alarm stations B1, B2, B3,..., Bn, and all communication equipment B / C forms a bus-type communication system A through the power line.

[0018] Such as figure 2 As shown, the alarm station B is composed of a wired spread spectrum transmission module 1, a control module 2, a voice compression module 3, and a line coupling module 4. External microphone MIC, speaker SPK, alarm button, check button, train axle temperature detector, smart card ( (Commonly known as IC card) police management system. Such as image 3 As shown, the main station C is composed of a wired spread spectrum transmission module 1, a control module 2, a v...

Abstract

The present invention discloses a passenger train alarm communication system. It is a communication system using broadcasting line or power line of passenger train to implement digital spread spectrum communication. Said system is formed from several alarm stations and a chift station, the alarm station and chief station include wired spread spectrum transmission module, control module, speech compression module and line coupling module respectively, and the alarm station also has microphone, loudspeaker, alarm button and review button, and is parallel-connected with train shaft temp. detector and intelligent card railway polizeman management system, and its chief station also is connected with radio station and train shaft temp. monitoring alarm device.

Description

Technical field: [0001] The invention relates to a passenger train alarm communication system. Background technique: [0002] my country is a continental country with a vast territory, and the distribution of resources, industrial allocation, land development, and economic development are still uneven. Railway transportation has the industrial characteristics of large transportation capacity, low energy consumption, low cost, all-weather, and light pollution; compared with other transportation methods, railway is superior in terms of regularity, accuracy, and safety. Railway transportation has obvious advantages in bulk cargo transportation, medium and long-distance passenger transportation, commuting and school transportation between big cities and suburbs, and tourist transportation in areas with dense natural and cultural landscapes. [0003] At present, my country's national operational railway mileage has more than 70,000 kilometers, including 20,000 kilometers of doub...
