Embodiment Construction

[0045] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0046] According to the relevant provisions of the national motor vehicle driver examination evaluation standard, the present invention designs a set of electronic examination venues, and designs and implements an assessment method corresponding to the examination venues. The site signal settings of the test site are as follows figure 2 as shown, figure 2 Among them, 21 is a photoelectric sensor transmitting end, 22 is a photoelectric sensor receiving end, 23 is a boom, 24 is a pressure-sensitive cable lead wire, and 25 is a pressure-sensitive cable. Hall sensors are installed on the boom, such as Figure 4As shown, 51 is a rod, 52 is a wire, 53 is a Hall sensor, and 54 is a strong magnet. The definition of switch signal in the venue is shown in Table 1:

Abstract

The invention provides a system and a method of detecting reverse shift of a tractor, which belongs to the field of traffic control. The system comprises photoelectric sensors, pressure-sensitive cables, hanging rods and a signal acquisition board, wherein each hanging rod is provided with a Hall sensor; each photoelectric sensor comprises a photoelectric sensor transmitting end and a photoelectric sensor receiving end; signals generated by the photoelectric sensors, the pressure-sensitive cables and the Hall sensors enter the signal acquisition board, and the signal acquisition board carries out data acquisition and forwarding; a first photoelectric sensor transmitting end is arranged at the left end of the left line of a road, and the right end is provided with a first photoelectric sensor receiving end; a second photoelectric sensor receiving end is arranged at the left end of the middle line of the road, and the right end is provided with a second photoelectric sensor transmitting end; and a third photoelectric sensor transmitting end is arranged at the left end of the right line of the road, and the right end is provided with a third photoelectric sensor receiving end.

Description

technical field [0001] The invention belongs to the field of traffic management, in particular to a system and method for detecting the reversing displacement of a tractor. Background technique [0002] The tractor is commonly known as a semi-trailer. The front and the body are separated, and a rotatable rigid connection is used between the two. The test site and test essentials for the reversing shift are very different from those of the vehicle with the front and the body as a whole, and the test requirements are also different. Big difference. The purpose of the test is to "assess the ability of the motor vehicle driver to control the tractor to move forward, reverse, correctly judge the wheel trajectory, and correctly park the vehicle in a limited area." The venue of the test subject is as follows: figure 1 shown. [0003] figure 1 Middle 1 is the length of a warehouse, and its length is the length of the tractor plus 1 meter. 2 is the road length from library A to l...
