摘 要
运输是实现人或物空间位置变化的活动，与人类的生产生活息息相关；因此，自铁路诞生以来，就因其运量大、速度快、安全可靠、方便快捷等优点，成为交通运输的主要力量。随着经济的发展，对铁路的要求愈来愈高，特别是随着信息化进程的加快，各行各业对速度的要求逐年增加，催生了高速铁路的产生。
高速铁路的发展离不开制动控制系统性能的提高；没有高效、安全、快速的制动系统，高速铁路是不可能发展起来的。因此，研制新的、性能优良的列车制动控制系统是当前发展高速铁路运输的关键。
制动控制系统是列车制动系统的核心部分，只有更好的控制才能实现更好的制动，因此，本文结合实际对制动控制系统中的制动控制单元进行了研究设计。目前的制动控制单元多采用微机控制，来实现制动控制的精确度、平稳性、安全性；因此本文也选用了LPC1768工控微处理器作为制动控制单元的主控芯片，来实现系统设计。
制动控制单元设计包括了硬件和软件设计。硬件设计主要包括中央处理器模块、DA/AD转换模块、开关量输入/输出模块、PWM波输出模块、显示模块、通信模块的设计；软件设计包括算法实现的软件设计、主控制程序设计、通信程序设计等。制动控制单元的控制算法采用的是模糊自适应PI控制算法。
论文对制动控制单元设计的相关理论进行了研究，在此基础上，进行了制动控制单元的软硬件设计，最后对制动控制单元的部分模块进行了验证性试验，试验结果表明符合设计要求，能够满足制动控制试验系统的性能要求。

Abstract
Transportation is an activity of realizing the variation of people and things space position, and it is closely linked with people’s production and life. Since the birth of railway, it has become the main power in the transportation because of its big traffic volume, fast speed, safety, and convenience etc. With the development of economy, the requirements for railway is higher and higher, especially with the quickening of the process of informatization , the requirements of all walks of life for the speed increase year by year ,and give birth to the generation of high speed railway.
High speed railway development is due to the improvement of the performance of the brake control system; No efficient, safe, fast brake system, high-speed rail is impossible develops. Therefore, the development of new and good performance of the train brake control system is the key of current development of high-speed railway transportation.
Braking control system is the core of the train brake system parts. Only better control to achieve better braking, therefore, this paper combining with the practice gives the research and design for the brake control unit of braking control system. The current braking control unit is more controlled by computer, to realize the brake control accuracy, stability and safety, therefore, this paper chooses the LPC1768 industrial control microprocessor as the braking control unit of the main control chip, to realize the system design.
Braking control unit design includes the hardware and software design. The hardware design includes the CPU module, DA/AD conversion module, switch input/output module, PWM wave output module, display module, and communication module design. The software design includes the algorithm of software design, master control program design, and communication program design, etc. Braking control unit control algorithm is adaptive fuzzy PI control algorithm.
The paper detailed analyzes the theory of design the brake control unit firstly, and on this basis, designs the hardware and software of brake control unit, and finally does the experiments on the modules of the brake control unit. The experimental results show that the braking control unit design gave in this paper accords with the design requirements, and can satisfy the performance requirements of the brake control test system.
