Description
Technical field
The present invention relates to field of automobile control, be specifically related to a kind of automobile overload real-time control system.
Background technology
Along with Chinese society economy more and more develops, highway construction paces are constantly accelerated, and mileage in highway open to traffic is constantly increased, and category of highways also improves constantly.But because increase interests are sought by driver or enterprise, the reasons such as awareness of safety is low, it is day by day serious that highway in China is transported the phenomenon transfiniting, Road Overload has become the key factor that Highway Pavement Structures damages, traffic accident takes place frequently, and this will become the persistent ailment that affects social economy's harmonious development undoubtedly.According to incomplete statistics, national highway division every year because of overload transportation produce extra roadupkeep cost of upkeep up to hundred million yuan of hundreds ofs.In order to administer Road Overload, highway administration department is check implement in the toll station of key road segment is provided with axle, but this method of inspection belongs to passive detection, and has artificial intervention.Need the strong and automobile overload real-time control system fast and accurately of stable a, antijamming capability for this reason.
Summary of the invention
For overcoming above-mentioned deficiency, technical matters to be solved by this invention is to provide strong, easy to operate, the full automatic automobile overload of a kind of antijamming capability real-time control system.
The present invention completes by the following technical solutions:
Automobile overload real-time control system, comprise detection module, radio receiving transmitting module, Single Chip Microcomputer (SCM) system, control alarm module and LCD display module, wherein detection module is connected with the wireless sending module in radio receiving transmitting module, the wireless receiving module of radio receiving transmitting module is connected with the input end of Single Chip Microcomputer (SCM) system, controls alarm module and is connected with the mouth of micro controller system with LCD display module.
In such scheme, the input end of described Single Chip Microcomputer (SCM) system is also connected with a keyboard release circuit.
In such scheme, described detection module comprises pressure sensor, Signal Collection and amplify circuit, signal conversion read module and collection point treater, wherein the input end of Signal Collection and amplify circuit is connected with pressure sensor, the input end of its mouth and signal conversion read module is connected, the mouth of signal conversion read module is connected with the input end of collection point treater, and the mouth of collection point treater is connected with wireless sending module.
In such scheme, described Signal Collection and amplify circuit can be instrument amplifier AD620.
In such scheme, the analogue to digital conversion that described Single Chip Microcomputer (SCM) system mainly realizes each node completes obtaining with data communication and the master control system of radio receiving transmitting module of weight information the weighted count of each point load carrying ability and overload is controlled.For meeting system requirements, described Single Chip Microcomputer (SCM) system is preferably C8051F330 micro controller system.
Beneficial effect of the present invention is:

Accompanying drawing explanation
Fig. 1 is the block diagram of automobile overload real-time control system of the present invention.
Fig. 2 is master control program FB(flow block).
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present invention and feature are described, illustrated embodiment is only for explaining the present invention, the scope being not intended to limit the present invention.
As shown in Figure 1, automobile overload real-time control system, comprise detection module, radio receiving transmitting module, Single Chip Microcomputer (SCM) system, control alarm module and LCD display module, wherein detection module is connected with the wireless sending module in radio receiving transmitting module, the wireless receiving module of radio receiving transmitting module is connected with the input end of Single Chip Microcomputer (SCM) system, controls alarm module and is connected with the mouth of micro controller system with LCD display module.The input end of described Single Chip Microcomputer (SCM) system is also connected with a keyboard release circuit.
Described detection module comprises pressure sensor, Signal Collection and amplify circuit, signal conversion read module and collection point treater, wherein the input end of Signal Collection and amplify circuit is connected with pressure sensor, the input end of its mouth and signal conversion read module is connected, the mouth of signal conversion read module is connected with the input end of collection point treater, and the mouth of collection point treater is connected with wireless sending module.In the present embodiment, described pressure sensor is selected the resistance strain weighing transducer based on metal strain effect, the built-in electric balance of this sensor, thus complete the conversion of resistance variations to change of voltage.Described Signal Collection and amplify circuit consists of instrument amplifier AD620, the small signal (voltage) of sensor bridge output is amplified to the identification so that micro controller system is sampled.Described signal is changed read module into the built-in A/D sample circuit of C8051F330 micro controller system.In the present embodiment, described radio receiving transmitting module is monolithic radio frequency transceiving chip.
During the work of automobile of the present invention overload real-time control system, after system powers on, first initialization and the self check of C8051F330 micro controller system, LCD MODULE, radio receiving transmitting module, pressure sensor etc.Then enter detected state, node load cell signal is carried out to sampling processing, sampled data and nodal information are sent to main frame by wireless module.Main frame receives load-carrying data and deposits reception buffer zone in and record nodal information, i.e. whether normally node identification number carries out identification number scanning and judge data reception when receiving 4 minor node data aft engines.If system check point is dismantled or the unexpected impaired data that make main frame not receive this check point, the locked system of this node number of liquid crystal display, carries out autobrake and prevents artificial intentional dismounting and consequent system mistake measurement.After confirming that each check point is normal, main frame computes weighted to each node data, specifies the loading condition of vehicle whether normal and load carrying ability is shown in real time; If any extremely, overload behavior is carried out to alarm and complete stop action and demonstration.
