PC 104 总线是国际上最早的嵌入式计算机总线标准,是一种专门为嵌入式控制而定义的工业控制总线,它采用ISA总线架构,其总线之间的互联使用了104根信号线,包括地址线、数据线、控制线、时钟线、电源线。 PC 104 is the world's first bus embedded computer bus standard, specifically for embedded control is defined industrial control bus, which uses the ISA bus architecture, which is interconnected between the bus use signal line 104, an address comprising lines, data lines, control lines, clock lines, power lines. 在《中国铁路》杂志2005年第12期中一篇名为"电力机车远程实时监控系统的研究"的文章中介绍的车载数据采集单元的设计采用了与本发明近似的技术方案。 In the article "China Railway" magazine in 2005 the first period 12 article entitled "study of power real-time monitoring system of remote locomotive" in the design of on-board data acquisition unit described in the present invention uses a similar technology programs. 该方案提出:车载数据采集单元采集电力机车运行信息、状态信息及各种设备的状态信息。 The solution proposed: a data acquisition unit onboard electric locomotive information, status information and various status information of the device. 电力机车的运行、状态参数及故障信息主要来自机车控制系统。 Electric locomotive operating state parameter and fault information from the main locomotive control system. 其系统结构见图l:车载数据采集单元通过CPU卡管理其内部总线,控制各子模块的工作, 通过内部的接口转换模块将从微机控制拒、机车逻辑控制单元(LCU)和机车安全信息综合监测装置(TAX)取得的数据进行甄别、分类等预处理后经通信接口发送到卫星通讯单元,从而使地面中心通过卫星通信和GPRS通信与车载进行双向数据传输,地面中心将实时传回的机车运行状态信息及机车设备信息存储在地面中心数据库,供地面中心进行综合分析。 The system structure shown in Figure l: vehicle data acquisition unit through the internal bus CPU card management, control operation of each sub-module, the interior of the refuse through the interface conversion module from the computer control locomotive logic control unit (LCU) and security information integrated locomotive after the data transmission monitoring means (of TAX) were obtained by screening, classification pretreatment via the communication interface to the satellite communication unit, so that the center of the ground via two-way satellite communications and data transmission GPRS communication with the vehicle-mounted, the center ground return real-time locomotive operational status information and device information is stored in the ground locomotive central database, a comprehensive analysis for the center ground. 上述方案不足之处在于:(1) 不能记录机车的运行数据车载数据采集单元虽能实时向地面发送信息,但是受数据传输量的限制, 也只能从大量信息中提取必要的小容量信息传输,很可能使一些有用的机车运行数据忽略掉而没有记录存储下来,这就大大减少了提供给地面系统故障诊断的依据。 The above-described embodiment in that the shortcomings: (1) not recording data onboard the locomotive runs in real time, although the data acquisition unit transmits information to the ground, but by limiting the amount of data transmission, only a small capacity to extract the necessary information is transferred from the large amount of information it is likely to make some useful data locomotive ignored and no records stored, which greatly reduces the basis to provide ground fault diagnosis system. (2) 不能在线故障诊断车载数据采集单元本身不具备在线诊断功能,所有故障诊断只能通过地面系统进行处理,这样就降低了故障诊断的反应速度,同时也加大了地面系统的工作负担。 (2) can not fault diagnosis online vehicle data acquisition unit itself does not have line diagnostics, all faults diagnosis can only be processed by the ground system, thus reducing the reaction speed of fault diagnosis, but also increased the workload of the ground system. (3) 不能实时监测所有类型机车的运行状态信息。 (3) can not be real-time monitoring operational status information for all types of locomotives. 上述方案提到该车载数据采集单元只从微机控制拒、机车逻辑控制单元(LCU)和机车安全信息综合监测装置(TAX)采集信息。 The above-mentioned embodiment controls only the vehicle data acquisition unit refuse from the microcomputer, the locomotive logic control unit (LCU) and security information locomotive integrated monitoring means (of TAX) collection of information. 由此可以看出它采集的信息不够全面,对机车车载设备不具备开放性,无法满足各种车型信息化改造的需求。 It can be seen that the information collected is not comprehensive enough, locomotive onboard equipment is not open, unable to meet the needs of various models of information reform. (4)没有采用冗余设计机车车载数据采集单元的基本特性是对大量数据的高速处理,由于没有采用冗余设计, 一旦出现故障,数据的可靠性和连续性就无法得到保障了。 The basic characteristic (4) onboard a locomotive without redundant design data acquisition unit is a high-speed processing of large amounts of data, since no redundant design, once the failure, reliability and continuity of data can not be guaranteed. 发明内容有鉴于此,本发明解决的问题是提供一种机车状态信息检测与诊断记录的方法及装置,可以客观真实的记录机车运行状态数据并实现在线诊断。 SUMMARY OF THE INVENTION Accordingly, the present invention is to provide a problem detection and diagnosis of locomotive status information recording method and apparatus, can record the real objective locomotive status data and for online diagnostics. 为此,本发明提供的技术方案如下:一种机车状态信息检测与诊断记录的装置,该装置包括:数据采集单元和数据处理单元;所述数据采集单元用于与机车的车载设备进行实时数据通信,釆集机车的运行数据;所述数据处理单元用于读取数据采集单元采集的数据,并通过对所述数据按不同机车事件类型进行分类逻辑判断得到机车发生的各种事件,并将机车发生的所有事件及相关参数写入记录文件并存储,同时与地面实时通信, 完成车地之间数据的双向传输。 To this end, the present invention provides the following technical solution: an apparatus for detection and diagnosis of locomotive status information recorded, the apparatus comprising: a data acquisition unit and a data processing unit;

determining if the vehicle-mounted device via the information or not sent back, returning the error message, the main frame is re-transmitted query, the query again. 此外还可以在接收状态接收其它车载设备发送给自己的查询帧,经判断该查询帧有效后立即置为发送状态,并从数据存储器中读取相关数据发送给相应的车载设备,之后重新置为接收状态,准备接收车载设备的运行数据。 Furthermore the reception state may also receive other-vehicle device sends a query to its own frame, immediately after the query is determined by the effective frame set to the transmission state, and read data is sent to the corresponding vehicle device from the data memory, then reset to receiving state, ready to receive operational data on-board equipment. 还可以在接收状态实时侦听总线上的通信,并接收需要的数据,经判断数据有效后将数据存储在数据存储器的相应位置。 May also listen for the reception state in real time on the communication bus, and receives the desired data, the data is judged valid data is stored after the corresponding location in the data store. 通过上述三种方式实现与车载设备的通信并采集数据后存储,但本发明不局限于只通过以上方式来采集lt据。 Communication is achieved by way of the three-vehicle device after collection and data storage, but the present invention is not limited only to data collected in the above manner lt. 在采集数据并存储后,对所有数据按照不同机车事件类型进行分类处理:① 数字量事件处理:对数据中所有的数字量事件进行——判断,判断依据是数字量事件发生从0到1或从1到0的变化,如果本次判断出来至少有一个数字量事件发生了变化就将这些发生变化的数字量事件以及相关参数(如日期时间、公里标等)按照统一规范的格式写到记录文件中。 After the data collected and stored all the data processed according to different classification locomotive event types: ① Digital Event Processing: All of the digital data events - determination, it is determined based on the digital event occurred or from 0 to 1 change from 1 to 0, it is determined if the current digital event at least one of a change event will these and related digital parameters (e.g., date and time, and other standard km) is changed in accordance with a standardized format written record file. ② 定时事件处理:对数据中的定时事件进行一一判断,判断依据是定时事件在其规定的时间间隔点上(如时间变化5秒)发生了变化,若本次判断出至少有一个定时事件发生变化就把这些定时事件以及相关参数按照统一规范的;格式写到记录文件中。 ② the timing of the event processing: timing of the event data is determined one by one, is determined based on a timing event (e.g., time, 5 seconds) has changed at the point of its predetermined time interval, if it is determined that this has at least one timing event these changes put the timed events and related parameters in accordance with the unified standard; written to a log file format. ③ 模拟量事件处理:对数据中所有的模拟量事件进行一一判断,判断依据是模拟量事件大于、等于或小于阈值点(如机车速度变化5公里),如果本次判断出来至少有一个模拟量事件发生变化就将这些发生变化的模拟量事件和相关参数(如日期时间、公里标等)按照统一规范的格式写到记录文件中。 ③ analog event processing: the data for all analog events eleven judgment, judge based analog event is greater than, equal to or less than the threshold point (e.g., locomotive speed change 5 km), if the current is determined out of at least one analog these events will change the amount of change of analog and event-related parameters (such as date and time, mileage and other standard) written in accordance with a standardized format log file. ④ 故障事件诊断处理:故障事件可以分为两类,即部件级故障和整车级故障。 ④ diagnosis and treatment failure event: fault events can be divided into two categories, namely component level fault and vehicle-level failures. 部件级故障是其它车载设备对自身能够诊断出的故障,本装置识别后不做诊断处理;整车级故障是需要综合相关机车状态信息进行诊断的故障, 故障诊断的过程是根据故障征兆,运用规则库和推理机按一定的推理策略逐步完成的。 Level fault other member of its own vehicle-mounted device can diagnose the fault, the diagnosis process is not the unit identification; fault is a need for a comprehensive vehicle-level state information related to the locomotive, the failure diagnosis process is diagnosed according to the fault symptom, the use of rule base and inference engine according to a certain gradual completion of reasoning strategies. 规则库是基于故障树设计实现的。 Rule base is based on the fault tree design implementation. 故障树模型是一个基于研究对象结构、功能特征的行为模型,是一种定性的因果模型,以系统最不希望发生的事件为顶事件,以可能导致顶事件发生的其它事件为底事件,并用逻辑门表示事件之间关联的一种倒树状结构的逻辑。 Fault tree model is a behavioral model based on the study structure, function features, is a qualitative causal model to the system most do not want the incident to the top events to other events that may lead to top event for the end of the event, and with correlation between logic gate represents a logical tree structure down. 故障树定性分析的目的是寻找导致顶事件发生的原因或原因组合,识别导致顶事件发生的所有故障模式。 Fault tree qualitative analysis purpose is to find the cause or causes of the top event of a combination of reasons, identify all failure modes lead to top event. 每个故障现象对应一种故障树;例如:如无压无流作为故障树的顶事件, 底事件预备及预备形成的各种逻辑构成了该树的一条枝叶,底事件牵引命令及牵引命令形成的各种逻辑构成了该树的另一条枝叶。 Fault A fault corresponding to each tree; example: If no pressure no flow fault tree as the top event, event preparation and preliminary bottom is formed constitute a logical various branches of the tree, and pulling the end of the event command commanded traction formed various constitute another logical branches of the tree. 推理机控制协调规则库的运行。 Inference engine controls the operation of the coordination rule base. 电力机车系统复杂,情况多变,故障识别的复杂程度不能一概而论,故而在对机车故障进行推理诊断时,采用正向推理与反向推理相结合的办法,既保证了故障推理的准确性又保证了系统运行的高效性:针对一些只需少数规则就能表达清楚的故障,系统采用正向推理的方法,即系统将规则库中已有的信息与规则的前提条件进行匹配,再把匹配成功的规则所对应的结论作为新的事实进行下一轮的规则匹配,直到推导出最终结论。 Electric locomotive Complex systems, the situation is changing, the complexity of the fault identification can not be generalized, and therefore in the locomotive fault diagnosis reasoning, using way forward reasoning and backward reasoning combination of both to ensure the accuracy of fault reasoning and ensure efficient operation of the system: for some of the rules will be able to articulate just a few failures, system uses a forward inference, that the system will be a prerequisite for the rule base in existing information and rules to match, then the match is successful rules corresponding to the conclusions of the fact that as a new rule for the next round of matches until the final conclusion is derived. 在判断机车电气设备是否过载时,都是采用正向推理的方法。 When determining whether locomotive electrical equipment overload, is the forward inference method. 对于复杂故障则采用反向推理方法,这种推理方式,通常是先根据原始信息, 提出一个结论,然后,再用反向推理倒过来查找支持这个结论的证据,反复这个过程,直到得出结果。 For complex fault backward reasoning method is used, this line of reasoning, is usually the first based on the original information, make a conclusion, then, then backward reasoning upside down to find evidence to support this conclusion, repeat this process until the outcome . 具体的,对于所有整车级故障诊断的依据是对导致该故障发生的其它事件按照先后顺序进行逻辑判断,如果每个事件都符合规定的逻辑就可以诊断出发生了某一故障,否则判断为无故障发生;如果本次判断出机车发生了至少1个部件级或整车级的故障,就立即将故障事件和相关参数(如故障发生前后某时间段内相关参数的瞬变数据信息、日期时间、公里标等)按照统一M^范的格式写到记录文件中。 Specifically, for vehicle-level fault diagnosis based on all that other events leading to the failure of logical judgment in accordance with the order, if each event logical provisions can diagnose a fault occurs, otherwise judged no failure; if it is determined that this has occurred the locomotive level or at least one vehicle component level faults on the fault event and related parameters (e.g., data relating to transient fault parameters before and after a certain period of time immediately information, date time, kilometer mark, etc.) written to a log file in accordance with the unified M ^ range of formats. 如以牵引风机继电器故障为例,牵引风机继电器动作过程:当牵引风机断路器闭合、牵引风机隔离开关处于运行位和牵? As an example to traction fan relay failure, pulling the fan relay process: When the circuit breaker is closed fan traction, pulling the fan in a running position disconnector and the retractor? 1风机接触器吸合三个条件成立时,牵引风机即会启动起来,当风机达到一定的转速时,就能使牵引风机继电器达到其最低额定动作值,使其闭合。 1 fan contactor closed three conditions are satisfied, i.e., pulling the fan starts up, when a certain rotational speed of the fan, the fan will be able to relay the traction action reaches its minimum rated value, causing it to close. 牵引风机继电器故障是以牵引风机启动信号和牵引风机继电器的动作反馈信号来综合判断的,先对牵引风机启动信号的三个必要条件进行判断,如果确定牵引风机已经启动,再判断牵引风机继电器的动作反馈信号,如果未收到牵引风机继电器闭合的信号,则可以确定出现了牵引风机继电器故障。 Traction fan is pulling air blower relay fault operation start signal and the feedback signal to the traction fan relay comprehensive judgment, the first of three necessary conditions traction fan start signal is judged, if it is determined traction fan has started, then the fan is determined traction relay operation of the feedback signal, if the traction fan relay closure signal is not received, it can be determined that a traction fan relay failure. ⑤特殊事件处理:特殊事件记录是一些无规律输入的单个数据或多项数据的数据记录,该事件记录的内容可以不受限制,可用于系统的初始化阶^a、故障信息产生之时、某一事件发生之时或有地面请求之时。 Special event process ⑤: special event is a single data record number or irregular input data record items of data, which is recorded content event may not be limited, can be used for the generation of the initialization order of the system ^ a, failure information, a when the occurrence of an event or the ground of the request. 如果本次判断出来至少有一个特殊事件发生就将这些特殊事件和相关参数(如日期时间、公里标等)按照统一规范的格式写到记录文件中。 If it is determined this time that at least one of these special events will special events and associated parameters (e.g., date and time, and other standard km) in accordance with a standardized format written to the log file. 在记录文件后,机车如有故障事件发生,立即将故障信息按照严重等级从高到低依次发送到车地无线传输装置和司机室显示屏显示。 After the log file, if the locomotive fault event occurs, immediately turn the failure information is sent wirelessly to the vehicle transmission device and the display shows the driver's cab in accordance with the severity level from high to low. 同时定时判断从地面发送的点播信息,并回送相应的数据(包括状态信息、记录文件、故障发生前的历史数据)给地面;还可以实时接收地面发送来的故障处理建议,送到显示器显示。 While the timing is determined on-demand information transmitted from the ground, sending back the corresponding data (including state information, log file, historical data prior to the failure) to the ground; may also receive troubleshooting recommendations ground transmitted in real time to the monitor. 以上所述的实施例仅为本发明的较佳实施例而已,并不用以限制本发明, 凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。 Merely the preferred embodiment of the present invention, the above-described embodiment embodiments only, not intended to limit the present invention, any modifications within the spirit and principle of the present invention, the, equivalent substitutions, improvements should be included in the within the scope of the present invention.
