探讨计算机操控汽车检测的三种体系 探讨计算机操控汽车检测的三种体系汽车的布局变得越来越杂乱，主动化程度也越来越高。不过关于汽车行业来说，从微观视点来看计算机操控体系体现最为杰出的是在：汽车出厂前的功用测验、汽车出厂后的监控及汽车检测三大方面。下面咱们首要来看一下：Auto layout becomes more and more complex, increasingly high degree of automation. But the auto industry, from the microscopic point of view of computer control system of the most outstanding is embodied in three aspects: function test, car before leaving the car factory monitoring and detection. Lets first look at:1计算机操控体系在汽车功用测验方面的使用The use of 1 computer control system in automobile function test因为电子技能的飞速开展，测验技能一日千里。使用领先、老练的测验技能，是成功开发功用优秀、经济实用的汽车功用测验体系的基本原则。在汽车功用的测验方面，最常见的计算机操控体系包含：Because of the rapid development of electronic technology, test skills of a thousand li a day. The use of advanced, sophisticated testing skills, is the successful development of excellent performance, motor function test system of economic and practical principles. In the aspect of automobile function tests, including computer control system the most common:1.1 PLC操控体系1.1 PLC control system可编程序操控器PLC(Programmable Logic controller)操控体系:PLC是重要的机电一体化产物，其首要功用是开关量操控。起先首要用于代替继电器操控，当前已开展到具有模仿操控功用，因此使用规模也有所扩大，构成了以PLC为中间的操控体系模型。Programmable controller PLC ( Programmable Logic controller ) control system of electromechanical integration products: PLC is important, its main function is the switch quantity control. At first the first used to replace the relay control, the current has been carried out to imitate the control function, so the use of scale is expanded, which takes PLC as the central control system model.1.2 面向目标操控体系1.2 object oriented control system面向目标的操控体系是使用典型根底操控产物，对于特定使用目标进行体系描绘和二次开发，二次开发的重点是体系布局、专用体系或部件以及使用软件的开发。这种体系因为其对于性强，因此能够做到体系紧凑、价格低廉，并能完成EIC（电控、仪控、计算机）一体化。Goal oriented control system is a typical product of basic control, system description and the two development for specific target, key two times development is the development of system layout, special system or component as well as the use of software. This system because the strong, therefore can do system compact, low price, and can complete the EIC ( electronic control, instrument control, computer ) integration.1.3 DCS操控体系1.3 DCS control system分布式操控体系DCS(Distributed control of system)，DCS是当今汽车进程工业主动化的主控体系，特点是操控涣散、操作显现会集、体系具有很高的可靠性和很强的功用。Distributed control system ( Distributed DCS control of system ), DCS is the main control system of the automobile industrial process automation, control and operation characteristics, show gathered, system has very high reliability and strong function.1.4 模块化操控体系1.4 modular control system这些年操控模块和模块化操控体系得到开展。模块化操控体系是以模块为根底，组成高度可装备的、分布式收集操控体系，这种体系当I/O呈现毛病时，只需要互换毛病的模块，而不需交换整个体系。模块化操控体系的持点是：布局简略、装置便利、安排灵敏、可扩大性较好、可靠性高、保护便利。These control modules and modular control system have been carried out. Modular control system is based on module as the foundation, distributed highly equipment, collection control system, this system when the I/O fault, swap faulty module only needs, without exchange of the entire system. Modular control system features: simple structure, convenient device is arranged, sensitive, scalability, high reliability, good protection facilities.2.计算机操控体系在汽车监控方面的使用The use of computer control system in 2 aspects of the vehicle monitoring从上世纪末90年代，电子信息技能越来越多地进入交通运输部分，并逐步构成一个簇新的工程范畴，即智能交通体系ITS(Intelligent Trans Portation System)。所谓智能交通体系，就是经过选用领先的电子技能、信息技能、通讯技能等高新技能，对传统的交通运输体系及管理体制进行改造，然后构成一种信息化、智能化、社会化的新式现代交通体系。From the end of the last century 90s, electronic information technology more and more into the transportation sector, and gradually formed a new engineering category, namely the intelligent transportation system ( Intelligent ITS Trans Portation System ). The so-called intelligent traffic system, is through the electronic skill, the leading information skills, communication skills and other high-tech, transformation of transportation system and the management system of the traditional and modern traffic system, form a kind of information, intelligence, social.2.1车载端计算机操控体系的功用概括2.1 on-board computer control system function summary车载端计算机操控体系的功用可概括为：首要，准确定位:车载监控终端全天候24小时接二连三的接纳GPS卫星信号，然后为体系供给车辆的方位和速度，定位精度可达10米。其次，回忆功用:车载监控终端具有存储车辆方位/模仿量/反常信息的功用，并且可存储长达两个月的车辆方位/模仿量信息。第三，操控功用:车载监控终端接纳到监控中间的操控指令后，对车辆履行操控举措。第四，通讯功用:在GSM网络覆盖规模内，车载监控终端可与监控中间进行数据交换。最终，防劫报警功用:在车辆遭受掠夺时，驾驶员牵动一个荫蔽报警按钮，即可在自保的一起等候帮助。On-board computer control system functions can be summarized as: first, accurate positioning: vehicle monitoring terminal all-weather 24 hours one after another admission GPS satellite signal, then the system supply vehicle range and speed, positioning accuracy can reach up to 10 meters. Secondly, memory function: the vehicle monitoring terminal has the function of storage vehicle range / imitation / abnormal information, and can be stored for as long as the direction of the vehicle / two months of analog information. Third, control function: the vehicle monitoring terminal admission to monitoring the control instruction to perform, vehicle control measures. Fourth, communication function: in the GSM network cover scope, vehicle monitoring terminal and monitoring center for data exchange. Finally, anti-robbery alarm function: in the vehicle the plunder, the driver touches a silent alarm button, can be in the waiting to help themselves.2.2监控端计算机操控体系的功用概括2.2 the monitoring terminal computer control system function summary监控端计算机操控体系的功用能够概括为：首要，数据预处置:通讯服务器从Internet上接纳到车辆的信息之后对信息进行初始的验证、校验、数据日志处置。并将待处置的信息分发给有处置才能的监控终端。其次，数据盯梢:将移动车辆的实时方位以列表的方法显现出来。第三，盯梢监控功用:服务器端能够完成对多终端的盯梢监控，体系完成选用TCP/IP协议，选用此协议是因为该协议能够确保信息传输的可靠性和实时性。第四，报警功用:终端设备报警分为预告警，实践报警，以及报警免除三级报警状况，这首要为了防止误报警状况发作，当服务器端收到终端设备预告警信息，则弹出报警对话框，并且在预告警车号列表框中列出宣布预告警信息的车号，双击其车号能够使体系定位到该车上，预告警状况不会使体系主动定位该车号的终端。The monitoring terminal computer control system can be summarized as : the primary function, data pre-processing: after receiving communication server from the Internet to the vehicle information on the information for the initial verification, validation, data log disposal.
