摘　　要

運輸是實現(xiàn)人或物空間位置變化的活動，與人類的生產生活息息相關；因此，自鐵路誕生以來，就因其運量大、速度快、安全可靠、方便快捷等優(yōu)點，成為交通運輸的主要力量。隨著經濟的發(fā)展，對鐵路的要求愈來愈高，特別是隨著信息化進程的加快，各行各業(yè)對速度的要求逐年增加，催生了高速鐵路的產生。
高速鐵路的發(fā)展離不開制動控制系統(tǒng)性能的提高；沒有高效、安全、快速的制動系統(tǒng)，高速鐵路是不可能發(fā)展起來的。因此，研制新的、性能優(yōu)良的列車制動控制系統(tǒng)是當前發(fā)展高速鐵路運輸的關鍵。
制動控制系統(tǒng)是列車制動系統(tǒng)的核心部分，只有更好的控制才能實現(xiàn)更好的制動，因此，本文結合實際對制動控制系統(tǒng)中的制動控制單元進行了研究設計。目前的制動控制單元多采用微機控制，來實現(xiàn)制動控制的精確度、平穩(wěn)性、安全性；因此本文也選用了LPC1768工控微處理器作為制動控制單元的主控芯片，來實現(xiàn)系統(tǒng)設計。
制動控制單元設計包括了硬件和軟件設計。硬件設計主要包括中央處理器模塊、DA/AD轉換模塊、開關量輸入/輸出模塊、PWM波輸出模塊、顯示模塊、通信模塊的設計；軟件設計包括算法實現(xiàn)的軟件設計、主控制程序設計、通信程序設計等。制動控制單元的控制算法采用的是模糊自適應PI控制算法。
論文對制動控制單元設計的相關理論進行了研究，在此基礎上，進行了制動控制單元的軟硬件設計，最后對制動控制單元的部分模塊進行了驗證性試驗，試驗結果表明符合設計要求，能夠滿足制動控制試驗系統(tǒng)的性能要求。

關鍵詞　制動控制單元；模糊自適應PI；CAN總線；電空制動




































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.
