Abstract
The invention relates to a computer-controlled system for the overload of automobiles. The computer-controlled system comprises a pressure sensor, an alarm and a central processing unit which consists of an A/D converter (analog to digital converter), a central processor, a liquid crystal display and a D/A converter (6) (digital to analog converter), wherein the pressure sensor (1) which is arranged under the ground is connected with the input end of the A/D converter, the output end of the A/D converter is connected with the central processor (4) which is connected with the alarm (2) via the D/A converter (6), and the central processor (4) is also connected with the liquid crystal display (5). Through the adoption of the computer-controlled system, the problems that time and manpower are wasted and efficiency is low because the overload phenomena of the automobiles are stilled controlled by manpower at present can be solved.
Description
Technical field
The invention belongs to automobile technical field, relate to a kind of automobile overloading system, especially a kind of computer control system for overload of automobile.
Background technology
Along with the development of forwarding business, security becomes the focus of people's common concern.A lot of drawbacks of having travelled overload, especially can cause many injuries to automobile, for example, shorten automotive service life and accelerate the aging of parts, accelerate wearing and tearing and the variation of tire, acceleration motor damages, hard steering, and centrifugal force increases, affect the maneuvering performance of automobile, reduce braking ability, increase non-security offset from, shorten the steel spring plate life-span.When automobile is worn and torn, the probability that traffic hazard occurs is also greatly to increase.Automobile overload is overweight is the one of the main reasons that causes traffic hazard, it has a strong impact on the safety of national wealth and people's life, data show according to investigations, annual China reaches 10,000,000,000 more than because of overweight the suffered direct economic loss that overloads, and obviously shorten the overweight serviceable life that has also caused the vehicles such as automobile of overloading, therefore, how to judge that automobile overloading is a problem demanding prompt solution.At present when lade, whether overload monitoring is mostly to monitor by manual observation or by weighbridge to automobile, and this monitoring method has that feasibility is not high, lifting record is inaccurate, cannot realize the shortcomings such as remote monitoring.
But, still there is no a kind of device that automobile overload is monitored in real time at present, in a lot of situations, must need police to strengthen the dynamics of manpower monitoring, therefore, a lot of vehicles can select overload at night to travel, dangerous large.Therefore, need to invent a kind of perception in time report to the police and identify the computer control system for overload of automobile of car plate in the time of automobile overload.
Summary of the invention
The object of the invention is to still be controlled by manpower for current automobile overload phenomenon, waste time and energy, the deficiency of inefficiency, provides the computer control system for overload of automobile of a kind of automatic accurate induction, warning and identification information of vehicles.
To achieve these goals, the present invention has adopted following technical scheme:
A kind of computer control system for overload of automobile, wherein: this system comprises pressure transducer, central processing unit, alarm lamp, hummer and by A/D converter, monitoring device, liquid crystal display, D/A converter and car plate automatic identifier; Described pressure transducer is arranged on below ground and is connected with the input end of A/D converter; The output terminal of described A/D converter connects monitoring device; Described monitoring device is connected with hummer and alarm lamp respectively by D/A converter; Described liquid crystal display connects monitoring device and is connected with car plate automatic identifier.
Described monitoring device is also connected with infrared inductor, and infrared inductor is connected with the input end of A/D converter.
Described force-sensing resistor strain gauge pressure sensor.
Described car plate automatic identifier comprises signal judgement module, processing module, and signal judgement module is connected with processing module.
Principle of work: when work, more than pressure transducer is embedded in to ground, be convenient to vehicle from road by time sensed pressure, infrared inductor can be arranged on the side on road surface, for passing through of perception vehicle.Display is arranged in pulpit, is convenient to staff and observes at any time.In the time that a car passes through, first be that pressure transducer is experienced after weight signal, pass to A/D converter, A/D converter is passed to monitoring device after simulating signal is changed into digital signal, meanwhile, and the time that infrared inductor can perception vehicle passes through, signal is passed to monitoring device by A/D converter, monitoring device calculates after vehicle commander, and the normal load of judging vehicle according to different vehicle commanders is how many, then compares with the signal of pressure transducer impression.If when the signal of pressure transducer impression is greater than normal load, overload of vehicle is described, then monitoring device can be controlled hummer and report to the police with alarm lamp, and by car plate automatic identifier identification information of vehicles, finally information of vehicles and weight information is presented in liquid crystal display.Whole process realizes robotization completely, and whether staff can observe at any time vehicle and overload and information of vehicles.
Beneficial effect of the present invention:
The present invention introduces computer system in the monitoring of automobile overload, has saved the step of hand inspection, and automobile overload can be found in time, prevents that illegal vehicle from overloading and travelling to hide the phenomenon of inspection at night; The present invention is simple in structure, and sensitivity is higher, runs into overloaded vehicle and gets final product alarm, time saving and energy saving; Owing to also comprising infrared inductor, calculate the load condition of different vehicle according to vehicle commander, monitor at any time the overloading of various vehicles; Adopt car plate automatic identifier the information of vehicle can be shown to staff intuitively.

Accompanying drawing 1 is system control flow chart of the present invention.
In figure: 1. central processing unit, 2. display, 3. car plate automatic identifier, 4. infrared inductor, 5. pressure transducer, 6. A/D converter, 7. hummer, 8. alarm lamp, 9. D/A converter.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
Embodiment:
As shown in Figure 1, a kind of computer control system for overload of automobile, is characterized in that: this system comprises pressure transducer 5, alarm lamp 8, hummer 7 and by A/D converter 6, monitoring device, liquid crystal display 2, D/A converter 9 and car plate automatic identifier 3; Described pressure transducer 5 is arranged on below ground and is connected with the input end of A/D converter 6; The output terminal of described A/D converter 6 connects monitoring device; Described monitoring device is connected with hummer 7 and alarm lamp 8 respectively by D/A converter 9; Described liquid crystal display 2 connects monitoring device and is connected with car plate automatic identifier 3.
