Abstract

A road vehicle system has a micro controller system 1 that provides both vehicle control functions and provides protection against theft. Coupled to the controller is an input keyboard 3, a ROM memory for programme storage, an EEPROM 4 that is used for storage of identification codes and a serial interface 5. The identification data can be in the form of the vehicle owners name, chassis and engine numbers and the correct registration number. This data can be read and transferred to an output port for checking on the validity of any documents when a sale is made.

Description

Goal setting

Our goal is to fight the existing crime. Our invention cannot prevent arbitrary car theft. But our goal should be

• a) the discovery of unauthorized drivers,
• b) the discovery of forged documents,
• c) prevent the sale of stolen vehicles.

Problems can only be solved if they are discovered, specifically the causes are researched to counteract with the appropriate means to step. If we want to fight crime successfully, we have to we make changes in today's system.

Step 1 for problem solving

The extension of the document template for approvals with driver's license and Passport (for everyone). Official withdrawal of vehicle documents - vehicle registration and vehicle registration. The vehicle registration documents are declared invalid! Of the Vehicle registration is kept at the district office for safekeeping. As a replacement a copy of the vehicle registration document will be given. Through the mentioned Action could be taken from the criminals on the basis that they Cannot manipulate vehicle documents.

In the future, only the original vehicle registration certificate and one would remain at the district office Photocopy at the vehicle owner. By announcing and implementing this Criminal organizations could also make a decision from day X onwards individuals their stolen, manipulated and blanco Throw away or burn vehicle documents. By arrangement and Dutiful introduction of the electronic identification device could be a new control and security system is introduced, with which the Vehicle registration can be replaced.

Step 2 for problem solving (driving licenses)

Electronic storage of driver's license data. The driver's license number must match the number that appears on the display. So that in Future the authenticity of the driver's license will be checked.

Step 3 for problem solving (registration number)

Registration of the registration number. This means that the official License plate can be compared with the stored data. So that in In the future, the license plate cannot be exchanged or manipulated at will.

Step 4 for problem solving (outdated control system)

The display attached to the windscreen, which is connected to the circuit of the Vehicle is connected will light up when the MDAKS is started up. This enables controls without stopping the vehicles. Through this optical Unauthorized drivers can be recognized immediately.

The aforementioned procedure enables the police or border guards to do so in a targeted manner to search for unauthorized drivers or stolen vehicles. This  Proof of authorization through the illuminated display on the vehicle is unique in traffic history.

The problems like car theft, car pushing or insurance fraud cannot be solved without the MDAKS.

Our identification device is not suitable to prevent theft, but that, what we want to achieve with our system is: "Stolen vehicles and discovering fake documents and thereby selling them To prevent vehicles ".

We have now presented our invention almost completely. It consists of two Parts that must be purchased from the district office for a double receipt. It is designed with a data program at the registration offices programmed. The data can be shown on the display on the windscreen will.

An arrangement is also necessary

The illuminated display must always be carried and every time you drive to be on.

What we haven't reported yet is the secret code, which everyone Receives vehicle owner upon delivery of an MDAKS. (The code is the Key to the device !!) The code number is entered before the start and that Device will check the number combination entered and at Approve the system. This doesn't just mean that the display lights up, but that all programmed data depending on the entered number can appear on the display.

What are the key security features of the new system with MDAKS?

• 1. Unauthorized drivers are discovered
• 2. Identity determination possible without stopping the vehicles
• 3. Crossing the border is not possible without MDAKS (this will execute a stolen vehicles prevented.)
• 4. By electronically storing personal data such as: Guide note number, The documents can no longer be used for the chassis number, registration number, etc. be faked.
• 5. Vehicles without MDAKS cannot be sold !!

How is the device itself protected?

• 1. The two-part MDAKS is not functional separately.
• 2. It cannot be used without a secret code
• 3. It is worthless without a double receipt
• 4. Changes can only be made by the approval bodies.

Here we see that our security measures are selected and varied are secured. We can also with our car control - and Security system prevent criminal acts.  

The procedures: withdrawal of vehicle documents and introduction of the new invention, will make car theft pointless and useless.

With our idea as well as procedures and arrangements we can achieve our goal realize.

This means:
Detection of forged documents and license plates.
Detection of unauthorized drivers.
Preventing the sale of stolen vehicles.
It is no longer possible to deport stolen vehicles abroad.

This will all be possible if we put the security system we have created into the Implement practice.

By this prevention reasons z. B.

• 1. Nobody buy a vehicle without an original vehicle registration document, because without it a vehicle cannot be registered.
• 2. Without a functional and programmed MDAKS, none could Border crossings take place in both directions.
• 3. Without proof of purchase (double receipt) the MDAKS becomes invalid and worthless.
• 4. Without MDAKS and double receipt, a vehicle cannot be deregistered or re-registered and not reprogrammed.
• 5. Without a double receipt and keyboard, the insurance will not be a premium Pay off in case of theft.
• 6. The MDAKS cannot be operated without a secret code.

These procedures are sufficient to sell and manipulate absolutely prevent stolen vehicles.

Industrial applicability

The MDAKS device is a road traffic control and security system built, as well as to prevent forged documents and stolen This device is useful for vehicles. It is inexpensive and only for certain Institutions available. Every vehicle should be equipped with this invention. The construction of these devices creates new jobs in the electrical industry created. It is a useful product and is used to fight criminals Actions. (A prototype of the MDAKS is available for demonstrations).

Summary

The MDAKS is classified in the stress category "Devices and processes" submitted.

Our device has its multifunction in that it has a uniform "Program procedure" is equipped. So identity and Security measures initiated and implemented. Unauthorized detection Vehicle drivers, detection of forged documents. It also prevents the sale of stolen vehicles and their deportation abroad. All processes, changes and applications are internationally practicable. Our control system offers a uniform program with which language barriers can be overcome. Our code system with stored data and information in our MDAKS are synchronized, which means that program content is connected with numbers. So z. B. in the program driving license number can be called up with the code number 5. This  Process and the meaning is such. B. in China, Albania or France understood the same way. All information can be called up individually manually but are also used by the traffic police or border guards handy infrared device.

Technical description of the "Multifunctional digital car control and security system"

The system consists of two units, the input and the output part.

Hardware of the input part: (see block diagram input unit)

The core of the input unit is a microcontroller (i) from the 8051 family. An EPROM or ROM is connected as program memory ( 2 ) via port 0 and port 2 of the microcontroller, the address and data bus. A keypad ( 3 ) with a 3 × 4 matrix is used to enter the data. This is connected to an 8 bit port of the microcontroller. A serial EEPROM ( 4 ) is used to store the personal data and the identification code. The connection to the output unit is established via a serial interface. A standard module of the MAX-xxx family ( 5 ) is used for level conversion. The vehicle electrical system (12 volts) is used to power the input unit. These 12 volts are controlled via a standard series regulator, e.g. B. with a 7805, converted to 5 volts. With the switch S1, which is connected to an I / O port of the microcontroller, you can jump to the program part "program EEPROM".

Software of the input part: (see flow chart input)

When switching on the supply voltage, e.g. B. when pressing the ignition key, a hardware reset is carried out on the input unit. This guarantees a safe start of the software. First, it is checked whether the program should branch to programming mode or normal program execution. If switch 1 is activated, the system branches to the EEPROM programming mode. If switch 1 is not actuated, the 6-8 digit ID code entered via the input keyboard is requested first. If the identification code entered does not match the code stored in the EEPROM, a flag is set and a new ID entry is expected. If 3 incorrect entries are made, the system is locked and can only be reactivated by a reset. If the code entered is identical to the code stored in the EEPROM, the system waits for a so-called function number. Function numbers and the identification code begin with an asterisk and end with the double cross. Any number of function numbers can thus be entered. If the microcontroller recognizes a valid function number, 16-digit information (e.g. name of the owner or chassis number of the vehicle etc.) is read from the EEPROM and sent to the output unit via the serial interface.

Each function number occupies a starting address for the data in the EEPROM. The program is now in a loop and waits for the next function number. In addition to the ID code for the owner also has an ID code for second users. Will the ID code for the second user are recognized Function numbers assigned to other EEPROM addresses. This z. B. necessary for rental vehicles.

Hardware of the output part: (see block diagram output part)

As with the input unit, the core of the output unit is a microcontroller ( 6 ) from the 8051 family. An EPROM or ROM is connected as a program memory ( 7 ) via port 0 and port 2 of the microcontroller, the address and data bus. To start a special program part, a coded infrared receiver ( 8 ) is connected via an I / O port of the microcontroller. The connection to the input unit is made via the serial interface of the microcontroller. A standard module of the MAX family ( 9 ) is used for level conversion for the V24 levels. A 16 × 1 display ( 10 ) with the corresponding digit height is used for data display. The display occupies 11 I / O ports of the microcontroller and can be addressed directly by it. The display requires a 5 volt supply voltage, just like the other modules. This is generated by the board network using a standard series regulator. A serial EEPROM ( 11 ) is used to store the data. With the switch S2, which is connected to an I / O port of the microcontroller, you can jump to the program part "program EEPROM".

Software of the output section: (see flowchart output)

When switching on the supply voltage, e.g. B. when pressing the ignition key, a hardware reset is carried out on the input unit. This guarantees a safe start of the software. The first step is to check whether the program should branch to programming mode or normal program execution. If switch 2 is activated, the system branches to the EEPROM programming mode. If switch 2 has not been activated, the program checks whether a special edition is necessary. This is queried by a coded infrared transmitter via the infrared receiver on an I / O port of the microcontroller. A special edition can e.g. B. be special data for the police, which can be started directly by the infrared transmitter. After checking whether a special edition is necessary, the sent ID code, which is sent by the input unit, is compared with the ID code which is stored in the output unit. If the ID code is not correct, the program always runs in a loop, special edition desired, new ID code correct. If a correct ID code has been recognized, the program checks which function number is desired. The input unit sends the data to be displayed after the function number. This data is now compared with the data stored under the function number on the output unit. If the data are identical, they are shown on the display. This data remains on the display until a special edition or a new function is requested. The system is now in a loop that continuously asks whether a new function is pending or whether a special edition is required.

Programming the EEPROM on the input and output unit. (see flow chart Program data)

The programming of the EEPROM's is done via the serial Interface of a personal computer. Was the S1 or S2 Input or output unit programming the EEPROM's requested, an identification number is first sent from the PC. This is checked for correctness by the respective unit. Is the Identification number wrong, the programming mode canceled. If the ID number is correct, the respective unit requests the data to be filed and then describes that EEPROM at the corresponding addresses. After transferring the the program runs in an endless loop and the last data Programming mode has ended.

Claims (7)

Car pushing and insurance fraud The idea: Invention and construction of an electronic identification device as multifunctional digital car control and security system "MDKAS". The invention is for a new modern control and security system in the Road traffic thought. The construction of the "MDAKS" was made possible by the high level and versatile use of electronics, but also by the use of digital display systems. Thanks to the possibility of combining both techniques, we have succeeded in developing the device mentioned. The device consists of two parts (units).

• a) The input unit with the input keyboard and
• b) The output unit with display for data output.

Input and output unit form one unit. Have separated from each other they have no function. The device can be used for proof of purchase (double receipt) can be purchased from the district office or from the border guard. This fact encourages us in our decision to file a patent application put! The existing problem (criminal acts)
The problem we want to tackle does not consist of phantom images or hypotheses. The criminal acts (car pushing) do a lot of material damage. We find that our complex of problems is diverse, explosive but not unknown. There is a reason why we still cannot fight vehicle crime decisively. According to our research, it is:

• 1) Vehicle documents in circulation, original, forged, manipulated and imitated blank documents.
• 2) Driver's licenses existing in the same way.
• 3) The official license plates (number plates) that can be faked and easily removed and attached to other vehicles.
• 4) The outdated, confusing control system with which controls can only be carried out sporadically. The current control system is not adapted to today's mass traffic.

The defective components mentioned above are actually the cause, that "car theft can happen". Despite all efforts, official Persecutions but also the setting up of insurance agents do not succeed to successfully tackle organized criminals. We claim that our Invention can help to overcome the complex of problems mentioned.
