UDS作为一种标准的诊断协议,定义了一套统一的服务和数据标识方法,其中DID就是其中之一,用于标识和访问特定的诊断数据。数据标识符(Data Identifier,简称DID)是一个关键概念。它不仅仅是一串数字或代码,更是连接着我们与车辆内部数据之间的桥梁。通过DID,技师们能够准确获取和诊断车辆各种重要信息,比如发动机状态、传感器...
所以,理论上讲,快照数据的采样可以在故障事件(Event)的任何时刻采集,即使Event没有异常也可以采集。具体来说,在一个驾驶循环内(One Operation Cycle),只要满足采样触发条件,即可对数据采样,也就是冻结目标快照组(Snapshot Group #n)中的多个DID(Data Identifier),示意如下: 而且,快照数据的采样可以只采样第一次,也...

DID占2字节,取值范围为0x00-0xFF,根据ISO14229-1规范,定义了诸多只能用于特定场合的DID,也就意味着大家都不能随意乱用DID,在使用DID Number应充分考虑到14229的要求,防止出现跟客户扯皮的现象。 如下图所示简要列举了较为常见的DID种类及其含义: 4 请求和响应 4.1 Single DID Format请求与正响应 以读取单个DID ...

You’d have to query DocumentDB with a known identifier—database or collection name or the identity value of a document—in order to get its selfLink so you could perform other operations. SelfLinks are still there, but you no longer need them to interact with an object. If you know ...
Enter an identifier of the style or classification of data, such as numeric, alphabetic, and date. Do not change the DD item data type if it is used within an existing application. Data types include these: Character: A single letter, always the size of one. ...
If you don’t have in mind a column or set of columns that might make a good primary key, consider using a column that has the AutoNumber data type. When you use the AutoNumber data type, Access automatically assigns a value for you. Such an identifier is factless; it contains no factu...
