    Preface

    According to the statistics of the Ministry of Public Security, in the first half of 2011, there were 1840998 road traffic accidents in China, an increase of 18502 cases over the same period of last year, with direct property losses of 440 million yuan. Indirect losses are even more incalculable. Traffic accidents are causing road congestion and disturbing people's travel every day. How to deal with traffic timely, accurately and quickly? The key to traffic accident scene disposal is to keep the road unblocked. At the same time, in the process of accident disposal, we should embody the guiding ideology of scientific and technological policing, use high-tech means to improve the efficiency of traffic accident scene disposal, and electronic management of traffic accident cases is also an urgent need of traffic police departments.

    Traffic Accident Site Drawing System in the past can only draw by computer from the original drawing standards of paper and pen, which makes the drawing standardized and unified. However, the drawing process is cumbersome, and it does not solve the problem of on-site investigation and measurement, and can not improve the speed of dealing with accident scene by traffic police, thus increasing the intensity and complexity of the work of traffic police. It also requires a long training process in computer graphics.

    "Photogrammetry System" also can not solve the problem of traffic accident scene investigation and survey, which is complicated in operation, weather-constrained, unable to use at night, unable to deal with large-scale traffic accident scene, can only carry out plane measurement, has large errors, and can not produce the detection report of measurement department, and the technical level of users. It's too demanding.

    The Traffic Accident Scene Survey System developed by our company in 2013 has fundamentally solved the problems of traffic accident scene investigation and mapping. It can not only realize standardization, integration and electronic management, but also be free from weather, light, waterproof, shockproof, dust-proof, industrial product design and use environment. Low requirements; easy to use; first-time users will; do not need a long training process; just click the button, you can accurately measure and plot; so that the survey of traffic accident scene becomes accurate, fast, easy and convenient. Improve the efficiency of dealing with traffic accidents, quickly dismantle accident sites, avoid traffic congestion and relieve traffic pressure, thereby reducing social and economic losses.

    (2) Surveying the scene of road traffic accidents

    1. Start on-site investigation of traffic accidents

    After the probe is turned on, click on the Smart Draw icon on the touch screen. The screen shows the start-up interface of road traffic accident scene investigation, as shown in the following figure (left). After that, it will automatically enter the traffic accident scene investigation guide, as shown in the following (right) chart:

    In the right picture, click the "OK" button at the top corner, which means that the current operation steps are completed and the next step can be performed.

    2. Procedures for scene investigation of traffic accidents

    In the following exploration and acquisition steps, all the symbols and roads follow the three principles of red, yellow and green. Red means: initial state, yellow means: selected state, green means: acquisition completed state.

    (1) Selection and acquisition of locating points

    When the traffic accident scene investigation guide is opened, no operation judgment is needed. The survey instrument will automatically guide the exploration steps. First, the screen shows the following picture:

    Select the location point to be collected directly by clicking on the touch pen. Take the street lamp as an example. The touch pen clicks on the street lamp icon. The screen shows as follows:

    Touch pen clicks on the red dot under the street lamp, the red dot becomes red to indicate that it can be collected. Workers go to the street lamp and close the top of the prospector to the street lamp (the closer the top of the prospector is to the pre-collection point, the more accurate the location of the collection) press the "ENT" key (or click "collection" with the touch pen), and the successful collection is yellow. When the display turns green, the acquisition is completed, and the touch pen clicks "OK" to enter the next exploration link.

    (2) Selection and acquisition of locating lines

    After collecting the locating points, the screen will automatically guide to the next step, select and collect the locating lines, as shown in the following figure:

    The locating lines are "straight line locating line" and "arc locating line", while the touch pen clicks "straight line locating line" as shown in the following figure (left); the touch pen clicks "arc locating line" as shown in the following figure (right):

    Taking the selection of "straight line positioning line" as an example, the touch pen clicks on any red dot (before and after the position part) and the red dot clicked turns yellow. This means that it can be collected. The staff go to the position of the pre-collection positioning line, press the "ENT" key (or click "collection" with the touch pen), and the yellow dot turns green. The second red dot is also collected.

    After the acquisition, the touch pen clicks "OK" and enters the next exploration stage.

    (3) Selection and collection of vehicle symbols

    After collecting the positioning line, the screen will automatically guide to the next link, select and collect the fixed icons, as shown in the following figure:

    The library is divided into eight categories: motor vehicle, non-motor vehicle, human body, livestock, dynamic traces, blood traces, safety facilities. Click on the menu of each category to show the thumbnails in the categories below.

    Under the thumbnail, there are four options: normal, left-turn, right-turn and overturn, which correspond to different shapes of icons respectively.

    Take the choice of "car" as an example, as shown in the following figure:

    The screen shows the car plane charts, the top is the front end of the car, and the bottom is the rear. Four red dots appear on the car charts. Two points can be selected arbitrarily as the acquisition points. The acquisition method is the same as the acquisition of the positioning point and the positioning line.
