【摘要】：經(jīng)過多年的發(fā)展,中國鐵路運(yùn)營里程數(shù)已經(jīng)達(dá)到12.4萬公里,位居世界前列。隨著“一帶一路”、“高鐵外交”戰(zhàn)略的實(shí)施,中國研發(fā)的軌道交通產(chǎn)品大量出口海外。列車作為鐵路相關(guān)設(shè)施的基礎(chǔ),是體現(xiàn)鐵路系統(tǒng)服務(wù)水平的載體。塞拉門作為列車的通道,其性能的優(yōu)劣直接影響列車運(yùn)行的安全性。我國塞拉門系統(tǒng)研究起步較晚,因此研究和開發(fā)滿足國內(nèi)列車發(fā)展需求、擁有自主知識(shí)產(chǎn)權(quán)的塞拉門控制器具有重大意義和實(shí)際應(yīng)用價(jià)值。本文根據(jù)項(xiàng)目需求設(shè)計(jì)一種基于DSP28335的塞拉門控制系統(tǒng),由帶霍爾無刷直流電機(jī)實(shí)現(xiàn)塞拉門的打開和關(guān)閉。根據(jù)功能說明書,塞拉門系統(tǒng)應(yīng)具有開關(guān)門、聲光報(bào)警、障礙物檢測、緊急解鎖、故障診斷、通信等功能。本文結(jié)合功能需求和列車實(shí)際情況對(duì)驅(qū)動(dòng)電機(jī)進(jìn)行選型,確定使用帶霍爾無刷直流電機(jī)。電機(jī)選型完成后,比較其幾種調(diào)速方法,最終確定了采用雙閉環(huán)直流調(diào)速系統(tǒng)控制無刷直流電機(jī)。本文經(jīng)過對(duì)單片機(jī)DSP2812和DSP28335的比較,設(shè)計(jì)了以DSP28335為核心的硬件電路。除了主控制電路,硬件電路還包括電源濾波、SRAM外部存儲(chǔ)、時(shí)鐘及EEPROM存儲(chǔ)、輸入輸出、模擬量采集、電機(jī)驅(qū)動(dòng)、顯示、通信等電路。為了門控器硬件電路維護(hù)方便,將輸出電路和主控電路設(shè)計(jì)成子板,通過連接器與主板相連。以硬件電路為基礎(chǔ),參照EN50128軟件標(biāo)準(zhǔn),本文設(shè)計(jì)了門控器軟件。該軟件包括了門功能邏輯控制、通信和故障處理三個(gè)模塊。門功能邏輯控制模塊以電機(jī)驅(qū)動(dòng)為基礎(chǔ),實(shí)現(xiàn)了車門打開和關(guān)閉;通信模塊實(shí)現(xiàn)了門控器數(shù)據(jù)的接收和發(fā)送;故障處理模塊對(duì)車門故障進(jìn)行診斷和處理,保護(hù)列車的行駛安全。最后利用塞拉門系統(tǒng)工裝和調(diào)試工具,對(duì)控制器的硬件和軟件進(jìn)行調(diào)試。為了保證調(diào)試結(jié)果的可靠性,本文設(shè)計(jì)大量測試案例,模擬了車門運(yùn)行過程中各種狀況的發(fā)生條件。根據(jù)實(shí)際測試情況,不斷優(yōu)化塞拉門控制器各項(xiàng)參數(shù)。長期的實(shí)驗(yàn)結(jié)果表明,本文設(shè)計(jì)的控制器達(dá)到預(yù)期的設(shè)計(jì)要求,可很好的應(yīng)用于車門控制。
[Abstract]:After years of development, China's railway operation mileage has reached 124,000 kilometers, ranking among the top in the world. With the implementation of the strategy of "Belt and Road" and "high-speed rail diplomacy," The rail transit products developed by China are exported overseas in large quantities. As the basis of railway related facilities, trains are the carriers of the service level of the railway system. The performance of the system directly affects the safety of the train operation. The study of the plug door system in China started late, so the research and development to meet the needs of domestic train development, It is of great significance and practical application value to control the plug door with independent intellectual property. According to the project requirement, this paper designs a control system of the plug door based on DSP28335. The opening and closing of the plug door is realized by the brushless DC motor with Hall. According to the function specification, the plug door system should have opening and closing, acousto-optic alarm, obstacle detection, emergency unlock, fault diagnosis, In this paper, the driving motor is selected according to the function requirement and the actual situation of the train, and the brushless DC motor with Hall is selected. After the motor selection is completed, several speed regulation methods are compared. Finally, the double closed-loop DC speed regulation system is used to control brushless DC motor. After comparing the single chip microcomputer DSP2812 and DSP28335, the hardware circuit based on DSP28335 is designed, except the main control circuit. The hardware circuit also includes external storage of power filter, clock and EEPROM storage, input and output, analog acquisition, motor drive, display, communication and so on. The output circuit and the main control circuit are designed as sub-boards, which are connected to the main board through connectors. Based on the hardware circuit and referring to the EN50128 software standard, the software of gate controller is designed in this paper. The software includes the logic control of gate function. The logic control module of door function is based on motor drive to realize the door opening and closing, and the communication module realizes the data receiving and sending of gate controller. In order to ensure the reliability of the debugging results, the fault handling module diagnoses and handles the door faults, and protects the safety of the train. Finally, the hardware and software of the controller are debugged by using the tool of the plug door system and the debugging tools. In this paper, a large number of test cases are designed to simulate the occurrence conditions of various conditions during the running of the door. According to the actual test conditions, the parameters of the plug door controller are continuously optimized. The long-term experimental results show that, The controller designed in this paper meets the expected design requirements and can be applied to door control.
