The utility model discloses the early warning that can accurately, effectual carry out the freight train and turn on one's side.
Description
Technical field
The utility model belongs to field of traffic safety, relates to a kind of lorry rollover early warning system.
Background technology
In recent years, along with the fast development of logistics transportation, goods stock cumulative year after year, particularly shipping growth rate in western mountainous areas is swift and violent, but due to the restriction of landform, economic dispatch factor in mountain road, inevitably take some limit index in highway layout, various sharp turns steep slope road section occurs again and again.Truck due to its center of gravity high, the large and feature of hurrying up in conjunction with China driver Duola of load-carrying, the major accidents such as bend section sideslip, rollover take place frequently, and bring huge loss to the people's lives and property.Based on this, the lateral stability of Real-Time Monitoring bend section truck, takes effective safety practice to seem particularly important in time.
At present, the measure adopted for truck bend section rollover accident is both at home and abroad the facility such as mounting vehicle anti-rollover control system (as: four-wheel steering, Active suspension, active lateral stabilizator and differential braking), the equipment detecting road information or navigational system in lorry mainly, the cost of each lorry promotes on the one hand, driver is difficult to accept,, above the lorry had, this type systematic or this system malfunctions are not installed on the other hand, make such mode costly, efficiency is low, effectively can not avoid accident.And at present domestic and international for heavy vehicle rollover evaluation index mainly side rake angle, side acceleration and transverse load transfer ratio three kinds, because the side rake angle of lorry rollover and the type of side acceleration threshold value and vehicle have larger relation, be difficult to direct mensuration, therefore the serious accuracy that have impact on mensuration, thus the early warning that lorry rollover can not be carried out accurately and effectively.
Utility model content
The purpose of this utility model is the shortcoming overcoming above-mentioned prior art, provides a kind of lorry rollover early warning system, the early warning carrying out lorry rollover that this system can be accurate and effective.
For achieving the above object, lorry described in the utility model rollover early warning system comprises single-chip microcomputer, variable information advices plate and some to pressure transducer, each pair of pressure transducer is located on bend section along lorry direct of travel successively, two pressure transducers in each pair of pressure transducer lay respectively on the road surface of both sides, bend section, the output terminal of each pair of pressure transducer is connected with the input end of single-chip microcomputer, and the output terminal of single-chip microcomputer is connected with the control end of variable information advices plate.
Variable information advices plate is mounted on the side in bend section, and single-chip microcomputer is fixed on the back side of variable information advices plate.
Spacing in each pair of pressure transducer between two pressure transducers is identical with the spacing between two wheel centers that axletree same in lorry is connected.
Spacing in lorry between adjacent two axletrees is the integral multiple of spacing between adjacent two pairs of pressure transducers.
Described single-chip microcomputer is MSP430 single-chip microcomputer.
When lorry normally travels, the font of variable information advices plate display is green; When lorry is driven over the speed limit, the font of variable information advices plate display is red.
The utility model has following beneficial effect:
Lorry rollover early warning system described in the utility model is by the pressure information of each wheel of pressure transducer Real-time Obtaining, then the pressure information of each wheel is forwarded in single-chip microcomputer, single-chip microcomputer obtains the lateral load transfer ratio of lorry according to the pressure information of each wheel, then judge whether lorry occurs risk of turning on one's side according to the lateral load transfer ratio of described lorry, when lorry vehicle insurance rollover risk, then inform driver by variable information advices plate, thus realize the early warning of lorry rollover, alarming effect is reliable, react fast, highly sensitive, and cost is lower, maintenance is convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is vertical view of the present utility model.
Wherein, 1 be pressure transducer, 2 be lorry, 3 be variable information advices plate, 4 for single-chip microcomputer.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to figure 1 and Fig. 2, lorry described in the utility model rollover early warning system comprises single-chip microcomputer 4, variable information advices plate 3 and some to pressure transducer 1, each pair of pressure transducer 1 is located on bend section along lorry 2 direct of travel successively, two pressure transducers 1 in each pair of pressure transducer 1 lay respectively on the road surface of both sides, bend section, the output terminal of each pair of pressure transducer 1 is connected with the input end of single-chip microcomputer 4, and the output terminal of single-chip microcomputer 4 is connected with the control end of variable information advices plate 3.
Need to illustrate be, variable information advices plate 3 is mounted on the side in bend section, and single-chip microcomputer 4 is fixed on the back side of variable information advices plate 3; Spacing in each pair of pressure transducer 1 between two pressure transducers 1 with and two wheel centers that same axletree in lorry 2 is connected between spacing identical; Spacing in lorry 2 between adjacent two axletrees is the integral multiple of spacing between adjacent two pairs of pressure transducers 1; Single-chip microcomputer 4 is MSP430 single-chip microcomputer; When lorry 2 normally travels, variable information advices plate 3 shows green normal driving information; When lorry 2 is driven over the speed limit, when lateral direction of car roll stability is poor, variable information advices plate 3 shows red information warning.
Specific works process of the present utility model is:
Lorry 2 is along in the runway direction running of bend, pressure transducer detects the pressure information of freight car wheel, the pressure information detected is forwarded in single-chip microcomputer 4 by each pair of pressure transducer 1, if the pressure information that two pressure transducers 1 in i-th pair of pressure transducer 1 detect is respectively F
1iand F
2i, single-chip microcomputer 4 is by pressure information F
1iwith pressure information F
2ithe result of additive operation is divided by pressure information F
1iwith pressure information F
2imake the result of sum operation, then by the results added of the division arithmetic of each pair of pressure transducer 1 correspondence, obtain lorry 2 lateral load transfer ratio LTR, when | when LTR| is more than or equal to preset value, then single-chip microcomputer 4 controls described variable information advices plate 3 and shows information warning in the mode of red font, thus remind the current lorry 2 of driver to have the risk of rollover, when | when LTR| is less than preset value, single-chip microcomputer 4 controls variable information advices plate 3 and shows in the current normal traveling of lorry 2 in the mode of green font, preferably, described pre-set threshold value equals 0.75.
