Description
Technical field
The utility model relates to sensing device, especially relates to a kind of sensing device that is applicable to the overload of vehicle monitoring.
Background technology
In the very flourishing China of logistics transportation, the lorry long-distance transport becomes indispensable low-cost logistics distribution means, under economic interests drive, the phenomenon of overweight overload is very general, the traffic hazard that this is arranged and cause is of common occurrence especially, and personnel and social economy have been caused great injures and deaths and loss.Because the very serious overload of high capacity waggon has also produced serious damage to highway bridge, also brought extremely dangerous potential safety hazard for other passing vehicles.Although relevant management law enforcement agency has strengthened the dynamics of law enforcement, the overload phenomenon still remains incessant after repeated prohibition, and shows according to related data, and the lorry accident more than 30% is owing to the overload transportation causes, and the direct economic loss proportion is especially up to more than 50%.The monitoring of overload of vehicle is always perfect, from static state to dynamically, from the platform truck scale that passes through the earliest, the real-time monitoring of the overload of vehicle of vehicular till now can't allow the people very satisfied for the management and the control of overload of vehicle all the time.The detection of present existing overload of vehicle all exist many problems.Crossing weighbridge is the simplest mode, but can not effectively monitor in real time, because the limitation of Weight Station can cause the obstruction of traffic when a large amount of vehicles need detect.A weight of compartment loading is mainly measured in monitoring for the overload of vehicle in fact, and this measurement can be divided into direct measurement and measure indirectly, directly measuring is exactly the weight of directly measuring the compartment by the sensor of the dynamometry of weighing, all there is proposition in this scheme several well-known manufacturing enterprise at home, and the sensor of the dynamometry of weighing is installed between compartment and car beam exactly.And weighing and force-measuring transducer will reach accurate weighing is that certain requirement and circumscribed is arranged.At first require all gravity of compartment load-carrying all must be pressed onto on the sensor, require compartment self can be as much as possible movable and be not subjected to the constraint of external force value.This mounting means has just produced three problems, if first compartment requires not to be subjected to the influence of boundary limitation power relatively more movable, spacing between compartment and the car beam just had problem so, for vehicle the compartment should with being connected of the complete close and firm of vehicle, this is the basic demand of vehicle safety.The second, because the height factor of the size sensor of sensor, the compartment will be by bed hedgehopping, and the center of gravity of vehicle also just is elevated, and this has just caused potential safety hazard to vehicle in turning and climb and fall; The 3rd, because the size restrictions of sensor, the contact pressure-bearing surface of the sensor of the existing dynamometry of weighing is all smaller, this also is because the cost factor of sensor production is limited to, so just changed the original stressed distribution in compartment, power all was directly delivered on 2 girders of car after originally the compartment loaded weight, be that the line face is stressed, and on girder, adorned several sensors now, just become several points stressed, in the process of long-term loading weight, the compartment can produce deformation, so the compartment also must be through very strict reinforcing and repacking, this is not paid attention to by present producers.This also will bring great potential safety hazard.More than 3 vehicle structures that all shown change that this mounting means is serious, must have the vehicle production producer of specialty and the vehicle technology administrative authority of specialty to install and verification, detect again and examine and could implement.This is exactly a baseless gossip for installing additional of used car fully.
Chinese patent 200410083020.6 discloses a kind of vehicle carried dynamic detector for automobile loading weight, by loading body, force cell, accelerograph, the control display keyboard is formed, the automaticity height, easy and simple to handle, only need driver one people just can finish the direct measurement to actual pay load, the self-monitoring and the overload early warning of dead weight capacity in the pilothouse under steam.This device can be used as the functional devices equipment automobile of modern truck indispensability.The described sensor of this patent application just is mounted between compartment and the crossbeam, and there is above-mentioned shortcoming in the complete pressure-bearing in compartment on sensor.
