Description

一种确保电力工程车辆行驶安全的方法及装置A method and device for ensuring driving safety of electric engineering vehicles

技术领域technical field

本发明属于电力工程作业车辆领域,尤其涉及一种用于消除驾驶员视野盲点的方法及其装置。The invention belongs to the field of electric engineering operation vehicles, and in particular relates to a method and a device for eliminating blind spots in the driver's field of vision.

背景技术Background technique

在实际工作中,各种电力设备有很多都是安装在作业环境复杂,无良好道路条件或地面条件复杂的地点。In actual work, a lot of various electrical equipment are installed in places with complex working environment, no good road conditions or complicated ground conditions.

随着机械化施工的应用和发展,越来越多的大型电力工程车辆(包括电力抢险车辆)被用于日常电力施工、巡检或现场设备维护、抢修工作中,大大提高了现场室外施工、抢修工作的工作效率。With the application and development of mechanized construction, more and more large-scale electric power engineering vehicles (including electric emergency vehicles) are used in daily power construction, patrol inspection or on-site equipment maintenance and repair work, which greatly improves the field outdoor construction and repair work. work efficiency.

同时,随着工作环境的复杂多样化,电力工程车辆所发生的各种行驶/驾驶类事故也随之增多。At the same time, with the complexity and diversification of the working environment, various driving/driving accidents of electric engineering vehicles have also increased.

为了保证车辆的行驶安全,各汽车生产厂家大量采用了各种主动安全、被动安全系统,最大可能地提高汽车的驾驶安全性能,在这些安全技术中,熟知的有安全带、安全气囊、安全头枕、防抱死制动系统等;目前处于推广应用或已经大规模使用阶段的技术有电子制动力分配系统、牵引力控制系统、电子稳定控制系统、盲点信息系统、碰撞警示系统等。In order to ensure the driving safety of vehicles, various automobile manufacturers have adopted a variety of active safety and passive safety systems to maximize the driving safety performance of automobiles. Among these safety technologies, seat belts, airbags, safety head Pillow, anti-lock braking system, etc.; technologies that are currently in the stage of promotion and application or have been used on a large scale include electronic brake force distribution system, traction control system, electronic stability control system, blind spot information system, collision warning system, etc.

在一些中、高档汽车上,配有一种盲点监测系统。所谓盲点监测系统,就是通过雷达、摄像头等装置,在车辆行驶时对车辆两侧的盲区进行探测,如果有其他车辆进入盲区,会在后视镜或其他指定位置对司机进行提示,从而告知司机何时是“并线”的最好时机,大幅度降低了因“并线”而发生的事故。On some medium and high-end cars, it is equipped with a blind spot monitoring system. The so-called blind spot monitoring system is to use radar, camera and other devices to detect the blind spots on both sides of the vehicle when the vehicle is driving. If another vehicle enters the blind spot, it will prompt the driver in the rearview mirror or other designated positions to inform the driver. When is the best time to "merge" and greatly reduce the accidents caused by "merge".

例如,沃尔沃的BLIS(BlindSpotInformationSystem)盲点信息系统,是在两个外后视镜下各安装有一个摄像头,可以监测到车后9米,两侧各宽3.5米的区域,这正是车辆行驶中,从内后视镜和外侧后视镜中看不见的一个视觉死角,称之为盲区,如果盲区内有车辆行驶,对本车“变线”形成危险,车辆A柱(车辆前挡风玻璃和前车门之间的立柱)上的一个红灯就会闪烁,并发出嗡鸣警报,对驾驶员进行提示,此时“变线”危险。For example, Volvo's BLIS (BlindSpotInformationSystem) blind spot information system is equipped with a camera under the two exterior rearview mirrors, which can monitor the area 9 meters behind the car and 3.5 meters wide on both sides. , a visual blind spot invisible from the inside rearview mirror and outside rearview mirror is called a blind spot. If there is a vehicle driving in the blind spot, it will pose a danger to the car's "lane change". The A-pillar of the vehicle (the front windshield and A red light on the pillar between the front doors) will flash and a buzzing alarm will alert the driver that "changing lanes" is dangerous.

但是,出于制造成本的考虑,这些主、被动安全技术通常都是配备在一些中、高档轿车或越野车上,对于电力工程车辆这样的现场施工作业车辆,鲜有配置。However, due to manufacturing cost considerations, these active and passive safety technologies are usually equipped on some medium and high-end cars or off-road vehicles, and are rarely configured for on-site construction vehicles such as electric engineering vehicles.

而且,在实际现场驾驶操作作业过程中,由于内、外后视镜观察盲区的存在,驾驶人员通常是无法观察到车辆右前轮前方或侧方位(即右侧A柱的侧方位)的实际地面情况的,这给电力工程车辆在地面条件复杂的地点的移动和行驶带来极大困难和不便,亦影响到现场施工作业的安全和顺利、快速进行。Moreover, during the actual on-site driving operation, due to the existence of blind spots in the interior and exterior rearview mirrors, the driver is usually unable to observe the actual position of the front or side of the right front wheel of the vehicle (that is, the side of the right A-pillar). This brings great difficulty and inconvenience to the movement and driving of electric engineering vehicles in places with complex ground conditions, and also affects the safety, smooth and rapid progress of on-site construction operations.

若对于现有的电力工程车辆加装上述的盲点信息系统,一是改装成本较高,且只能对车辆两侧中、后方向的盲区进行示警,无法解决车辆右侧前方的视野观察难题;二是这种改装往往需要涉及到汽车原有控制线路部分的改动,而且对车辆的改装,还受到公安机关车辆管理部门各种规定的限制,车辆管理职能部门对改装车设置了很高的门槛,如何使对车辆的改装符合车辆管理部门各种规定的限制,也是实际车辆设备管理中的一个难点。If the above-mentioned blind spot information system is installed on the existing electric power engineering vehicle, firstly, the modification cost is relatively high, and it can only warn the blind spots in the middle and rear directions on both sides of the vehicle, which cannot solve the problem of visual field observation in front of the right side of the vehicle; The second is that this kind of modification often involves the modification of the original control circuit of the car, and the modification of the vehicle is also restricted by various regulations of the vehicle management department of the public security organ. The vehicle management functional department sets a high threshold for the modified car , How to make the refitting of the vehicle conform to the various regulations of the vehicle management department is also a difficult point in the actual vehicle equipment management.

如何在现有车辆所配备的各种辅助驾驶装置(例如倒车雷达、内/外后视镜等)的条件下,花费最小的成本,帮助驾驶员观察到车辆右前轮前方或侧方位的实际地面情况,使其尽可能全面地掌握车辆外部(特别是车辆右前轮的前、侧方位)的现场地面情况,是实际现场工作中迫切需要解决的问题。How to help the driver observe the actual position in front of the right front wheel or side of the vehicle at the minimum cost under the conditions of various auxiliary driving devices (such as reversing radar, interior/exterior mirrors, etc.) equipped with existing vehicles It is an urgent problem to be solved in actual on-site work to make it possible to grasp the on-site ground conditions outside the vehicle (especially the front and side orientation of the right front wheel of the vehicle) as comprehensively as possible.
