2. Communication majors may include: closed-circuit television, broadcasting, clock, power supply, PIS, official telephone, special dispatching telephone, special wireless dispatching telephone, transmission system, public security fire control system, public network system, etc. There are many majors.
3. Signal major: a very professional system with only a few textbooks. Because of their strong pertinence, most of them are books compiled by the national railway subway.
4. If you are a part-time professional, the personal recommendation primer is as follows. In particular, professional books are written for equipment and need to be combined with equipment learning, so they are not recommended.
1) operation and maintenance of urban rail transit communication signal system/edited by He, Wang Songzi and He. The editor-in-chief is the former technical manager of Guangzhou Metro and an expert in the domestic subway industry. A good primer. City libraries with subways can borrow them.
2) Technical Manual for Installation of Communication Signal System of Urban Rail Transit/edited by Qin Zhao, Liu Ping and Niu Xuezhong. This book mainly describes the principle of installation procedures, emphasizing the pertinence, practicability and effectiveness of construction technology, installation quality and safety precautions.
3) Railway Communication Signal/edited by Li. : Southwest Jiaotong University Press, 20 1 1 year. This book systematically introduces the basic concepts, basic knowledge and equipment principles of railway communication signals. The book consists of eight chapters, including: signaling, railway signaling infrastructure equipment, interval blocking equipment, station interlocking equipment, centralized dispatching and dispatching supervision, hump signaling equipment, crossing signaling, etc.
4) Communication Technology of Urban Rail Transit/Shanghai Shentong Metro Group Co., Ltd. Rail Transit Training Center, China Railway Press.
5) Full-time specialized courses (including technical secondary school to undergraduate course), including circuit theory foundation, electronic circuit, advanced mathematics, microcomputer principle and interface technology, urban rail transit signal and communication system, digital communication, program-controlled exchange foundation, optical fiber communication application, train automatic control technology, automatic block foundation, digital communication system, basic circuit analysis, etc.
In some places, customized classes (specialized courses) include: circuit foundation, electronic circuit, signal and system, microcomputer principle and interface technology, computer communication, station signal, interval signal, hump signal, railway signal remote control signal measurement and processing, computer foundation, circuit foundation and computer communication.
