Taser - Stungun Semi-Automatic Advanced Security System Concept Test for Volvo FH - 12

Truck theft in Peru is ranked among the 10 most dangerous countries in the world. In that sense, the registered cases of vehicle theft in the year 2012 were a total of 16 357 and in the year 2019 was 20 159 stolen vehicles increasing a percentage of 18.89% in only 7 years. This paper shows as an objective, the development of the Proof of Concepts of an Advanced Security System Taser - Stungun semi-automatic for Volvo FH - 12. In this system, a TTL device (PIC) is used as hardware and a voltage booster from 5v to 5000v generating protection for the easiest and most valuable parts to steal. The proof of concept is activated by the user by buttons and sensors assigned for the protection of the truck, since the installed devices will be aesthetically located in the truck to not be found by the thief, besides being very reliable so that the driver can use it, also in its installation. The prototype will use a shock as self-defense since the system will generate an electric shock of 10 mA with a frequency of 2 seconds, which can immobilize or temporarily paralyze the thief. Therefore, it will analyze the alternatives with the help of the morphological matrix to choose the ideal solution, then we will design the electrical circuit, the programming in pseudocode, validating the proof of concepts, and the selection of the insulator. Finally, it must consider the correct selection of sensors and actuators thus allowing security reliability in different circumstances of the theft.


Introduction
Today, security is the greatest concern of all human beings living in South American countries with the highest crime rate, according to the UNODC.In this regard, the latest yearbook published by the Ministry of Transport and Communications on the vehicle fleet informs us that between trucks, tug, trailers, and semi-trailer amounts to 298 013 units that have been stolen in 2018, from these figures we can see the highest rate in complaints about theft of cargo trucks being 6 982 units only in Metropolitan Lima, which highlights one of the many problems that Peru is going through [1].Since this alarm system being used is only for warning, but not for action.To avoid these major challenges created by criminals, modern technology and devices must be used to protect the vehicle and its most expensive components, therefore, the vehicle defense strategy needs to have a new inventiveness [2].Today, alarm systems commonly known as GPS can be installed in vehicles.The project that we support will serve to provide more security to vehicles that are parked or moving, of course, it is not the only solution that will exist over time, but it will not have limitations in its installation [3].These security devices are practical devices that can be used by the driver, being that GPRS module is used to give messages and warning calls to the numbers previously assigned by the vehicle owner, this includes monitoring the instant real-time location of the vehicle unit, also the panic buttons will be distributed discreetly to avoid any suspicion of the thief.[4] Figure 1.Important parts of VDI2206 Methodology [15] The Mechatronics methodology [15] developed by "The Association of German Engineers" (Verein Deutscher Ingenieure, VDI) (VDI-RICHTLINIEN, 2004), was considered suitable for the execution of this research work, which is a practical guide for the systematic development of innovative mechatronic products.

Technical Analysis of Solution Concepts
At this stage an evaluation of the numerous alternatives is required, among them we have safety, easy handling, quality of work and the list of requirements must be fulfilled [17].Table N°2 shows the content of 3.3 that was evaluated to find the value of (Xi), which had several important points.

Table 2. Technical Analysis Economic Analysis of the Solution Concepts
The economic issue plays a very important role since the viability of the design depends on it.Therefore, it is very important to consider some aspects such as the number of components or parts, ease of construction or assembly, producibility, costs, and operation annexes, as well as a minimum of waste.
Table N°3 shows the content of 3.3 of title 3.3 that was evaluated to find the technical value of (Yi) which had several important points.

Figure 2. Final evaluation of optimal solution concept
For the design of the proof of concept was taken into account the analysis of the function which is delimited to adapt the other advantages, the size to be part of the advantages it should have, also security also plays an important role to avoid damaging the hurtador, the energy reused from the alternator and when you turn on the track is recharged, ergonomics is an advantage that must be met to be installed and mounted on the truck, the response time must be taken into account because with that advantage ensures fast operation, Another point is the knowledge of the product since there are predetermined integrated which are already coupled to the design, also the maintenance since as any electronic and mechanical device requires preventive or corrective maintenance, in that circumstance the type of technology is chosen to meet the different situations while maintaining ergonomics, flexibility and materials and finally the type of assembly that ensures proper installation is taken into account.The results of this analysis are shown in Table 4.

Technological Information
The Pseudocode has three buttons which two are interlocking, one-stop.Followed by a timeout that takes to turn on the PIR sensors, finally, the actuators are independent for each sensor, and finally the user interaction as the mechatronic self-defense device that protects the vehicle.The flowchart shown in Figure N°3 shows the actuation of three buttons, six sensors and their respective actuator which are cascaded and feedback with condictionals at a given time to ensure its operation.

Mechanical Design
The mechanical design is a complex task that allows establishing a transformation process, in that sense, the insulators that will be in the handles were designed to be glued with a special glue to not deteriorate and not get in the way of the handle, on the other hand, the nuts as both will be printed in 3D with PLA material, as it is more used in printers for its low cost and high durability and finally does not conduct electricity.In addition, they were taken into account the adaptation perfectly to human sight. Part 1 of the mechanical system located in Figure 4 is the box that will contain the control board and its components as well as the M8 and M12 connector outputs. Part 2 of the mechanical system located in Figure 4 is the PIR sensor bracket for easy addition to the truck. Part 3 of the mechanical system located in Figure 4 is the electrical discharge isolator that must be placed on each truck handle. Part 4 of the mechanical system located in Figure 4 is the electric shock isolator that must be placed as a washer on the truck drive unit adjusting bolts.

Electronic and Electronic Design
The electrical design is part of the process of planning and of electrical and electronic equipment, in that perspective electrical system, several criteria were taken to size the cables, such as environmental factors and the structure of the chassis of the Volvo, in addition to the output of the consumption of the sensors will be enhanced.
The input and output connections such as single contact, double contact, limit switch, sensor input, Taser connections, microcontroller reset button, microcontroller power supply are used to make the connections correctly and to activate the 8 actuators.[20].
Figure 5. Electronic System Design The material used to reproduce is resistant to vibration, weather precipitation.Consequently, the most important device is the TTL (PIC) which consists of a circuit of inputs and outputs creating an adjustable source of Taser modules in the PIR sensors.Figure N°05 shows the electronic design for the PCB board fabrication.

Proposed System
The material used and recommended that are resistant to vibration, weather precipitation, is the TTL device (PIC) which consists of a circuit of inputs and outputs with an adjustable source, Taser modules, and PIR sensors allow the system to have an estimated response time of 1.95 seconds calculated and have been made by other research resulting at the same time.[21] Figure 6.Wiring harness layout with their respective input, output, and control circuit connections.
The vulcanized cable will transmit 5 lines of cable of different colors to be used in the data transmission and power points, being necessary for the sensors and actuators, on the other hand, the cable diameter was determined according to the power required by the actuators which are N°16, the central box is an isolator of noise that is caused by the other mechanical and electrical accessories of the Volvo.Figure N°6 shows a schematic for a feasible installation where the different inputs (sensors) and outputs (actuators) can be observed.

Conclusions
The invention of this security system was determined by the insecurity that afflicts different parts of Latin America, due to the high numbers of theft to vehicle units, therefore, through this work is intended to develop an advanced device Taser -Stungun Semi-Automatic for Volvo FH -12, to provide greater protection to the vehicle unit and its parts.Consequently, as already observed in the course of this article, the proof of concept has addressed basic problems about the security system of the vehicles, being these elaborated with basic and compact mechatronic equipment that comply in providing necessary security but not the ideal and desired, since the proposed system improves the state of confidence of the owner establishing a safe condition for the truck in any public environment or criminal circumstance, therefore, the main objective is focused on providing security to the semi-trailers in an effective manner.In this context, it has been evidenced that the mechanical, electrical, and electronic design fulfills the purpose of creating security to heavy units, also the proposed mechanism leads us to the technical-economic feasibility that suits the purpose, therefore, the feasibility of the operability of this protection system in heavy vehicles was evidenced.On the other hand, it has been possible to compare the electronic system with other existing ones, being that the proposed offers greater security and that its configuration is based on the cost and benefit, this for the versatility at the time of installation as well as for the manipulation of the drivers, in that sense, the vehicle that is in danger the driver can activate the semi-automatic device to secure the vehicle with which an SMS will be sent to the pre-determined number, being this security system a reliable mechanism against the gadgets of criminals.In conclusion, the proof of concept will work to provide greater security to the vehicle since in the market there are different security devices against theft, but there is no specific one for heavy vehicles, in that context the system proposed by its delineation offers a comprehensive security mechanism that has been based on calculations and designs reaching to determine its effectiveness in any circumstance.Likewise, the system gives the possibility of being able to be conditioned to the different vehicle units, due to its mechanical and electrical structure, which are similar and should be a matter of another more exhaustive investigation.
