Description
Technical field:
The present invention relates to a kind of controller of vehicle, particularly relate to a kind of control setup of discharging vehicle.
Background technology:
Current China is in the period of large-scale city construction, no matter be road construction, still the construction in house, in the urban construction process, can produce a large amount of building waste Loaded goodss inevitably, topple in the place that these building waste Loaded goodss need rely on self-unloading earthwork car to be transported to appointment, because the environmental pollution that the noise that disturbs residents that self-unloading earthwork car brings and Loaded goods are unrestrained, and to the infringement of road, there is concrete requirement in each city to stroke route and the dumping ground of the dumping car of transportation building waste Loaded goods.And the chaufeur of self-unloading earthwork car is because self interest relations, and the constraint in the place of the time of often deliberately ignoring and not abiding by the regulations, the route of regulation, regulation stealthily is poured over Loaded goods spacious unserviced place nearby.Disorderly the Loaded goods of toppling over causes the obstruction of road, the pollution of environment, the injury of the person, and the problem that Loaded goods is disorderly toppled over has become a troubling persistent ailment in all urban construction.
In order to renovate random upside-down mounting loading phenomenon, each relevant department and agency has strengthened the method for management and the dynamics of punishment.Work at a selected spot in relevant highway section such as sending someone and to wait for, camera system is installed, minitrack is installed.Set up the news file of the fleet, license plate number, chaufeur etc. of Loaded goods car; To information such as the course in the vehicle traveling process, stop situation and berthing times, carry out synchronization monitoring by means such as gps satellite position fixing system, pick up cameras.Relevant information also in time transmits by monitor terminal, and relevant department rely on existing technology to be strictly on guard against the Loaded goods car in violation of rules and regulations, and in time mal-practices such as random upside-down mounting loading is handled in evidence obtaining by information sharing.
But there are the deficiency of four aspects in above-mentioned means and method.
1, prevent from disorderly toppling over and of overall importancely systematically to arrange net, equipment and personnel's investment cost is huge, and the phenomenon of disorderly toppling over has interim and zonal characteristics, concentrate and occur in around the preliminary stage and building site of construction, if spend the facility that huge fund construction one cover needs all roads of covering of long-time maintenance, whether be worth.
2, all facilities need dumping car, road, communication, each supervisory management zone closely and actv. cooperates, because relate to the difference of vehicle subordinate relation, the difference of personnel's subordinate relation, the difference of ability to shoulder economically, the difference in geographic position, the difference of weather condition, the difference of dumping ground environment, the difference of dumping ground management condition, the difference of dumping ground distance, the kind difference of toppling over, can not various aspects cooperate flawlessly, dead angle and leak are arranged unavoidably.Simultaneously, all equipment and method have limitation separately, and technological means can not be exhaustive, must have to allow the unrest person of toppling over who considers economic interests that the gap that can bore is arranged.
3, above-mentioned all equipment and method are the character of monitoring, just finishing the tracking of vehicle route can not control behavior in real time, implement quite difficulty of monitoring, disorderly topple over and catch that disorderly the person of toppling over is more difficult from monitoring out disorderly to be poured into to prevent, because disorderly the place of toppling over generally is the location part of the unmanned monitoring of remote emptying aperture, the time generally is in night and morning, so the unrest person of toppling over that can catch is quite difficult.
4, even the energy that costs a lot of money and material resources are caught the dumping car of disorderly toppling over, also want follow-up inputs manpower financial capacity punish processing because existing law not have direct clause of toppling at unrest, often can only be carelessly it, can not deal with problems.
So we think: because the difference of each urban construction scale, the difference of construction period, each city is in different periods, stroke route to the dumping car of transportation building waste Loaded goods is different with dumping ground, there is no need to spend huge investment go to build one may the efficient system facility.
Because it is many-sided producing the reason of disorderly toppling over, it also is many-sided disorderly toppling over the reason that can not prevent, there is not a kind of all-round way can solve all problems, prevent and disorderly topple over the problem concrete analysis of wanting concrete, will be at concrete situation, adopt most economical and actv. corresponding method solves.
Such as: it is far away to topple over the place, does not allow disorderly to topple over outside, topples in the place in and disperses greatly, and different kinds must be poured over different pour(ing) points, topples over the place and is provided with operating personal.
The situation that picture is above-mentioned, it is a local problem, the road and the zone that relate to minority, do not relate to all roads and zone, as long as the startup power of the lifting device of dumping car is grasped in the hand of the operating personal of toppling over the place, the chaufeur of dumping car can not start the lifting device of dumping car, has just thoroughly stopped random possibility of toppling over, there is no need to set up huge monitoring system, more there is no need to arrange long-term monitoring strength.
