Description

Autonomous fingerprint pedal lock Equipped with camera and shock system

The innovation refers to an advantageous technology in in the field of Electrical Engineering, Security .

In the previous technical knowledge, a kind of wooden lock was used in China and Egypt more than four thousand years ago. Later, with the development of industry in Europe, these locks were built in a simple form made of metal and more secure than wooden locks. At that time, Germany had a particular expertise in making delicate locks that made the keys and moving parts of the lock extremely prolific and tangled and toughened the toggles and beautifully decorated the appearance of the locks. But at that tumultuous time, the need for secure locks was felt that much progress was never achieved in the lock mechanism. Tangling of the toggles and hiding of the keyhole were the only safety means.

Differentiating with existing and recorded samples:

ELECTRIC LOCK FOR BRAKE, CLUTCH, AND/OR ACCELERATOR PEDAL OF AN AUTOMOBILE - US 2004/0163432 A1

1- all control actions of pedal lock can be done for wireless and remote control such as the exact date and time of the user, or the creation of user limits for using the pedal lock by admin, or the reset of the pedal lock circuit or the alarm system independent of the pedal lock and the AUTOMOBILE ECU performance control system, as well as awareness of damage to AUTOMOBILE lock and theft by sending a message or phone calling and locating by mobile application, and upgrading pedal lock firmware and such actions, while the invention, when failing pedal lock electronic circuit, is designed through a key and padlock to release the clutch and brake pedal of AUTOMOBILE, which this lowers the pedal lock safety factor, as well as the design of the applications and other above actions have not been stated.

2- A rechargeable lithium polymer battery with repeated recharging has been applied in my designed system that it can be used for 1 year with a 2 hour charging time, and when the battery is over, it is alerted either through the electronic pedal lock system and through sending data to mobile app, and while connecting, it's possible to know when the battery charge is finished, while there is no such thing in the invention.

3- An electric shock system and an images recording system during robbery has been used in my designed pedal lock circuit that the electric shock system is activated and applies a high voltage to the lock body while damaging the shackle and the body of the pedal lock; meanwhile the image recording system records a burglar's image and saves it on its SD card, it sends all data through serial communication when connected to the mobile app, while the invention does not have such a design.

4- In the lock made by me, considering the items and components used in the circuit, as well as the speed of better performance and greater accuracy, and in terms of its dimensions and its circuit size, and most importantly, optimizing the parts used inside the lock and its body and the high safety factor of the lock is remarkable, but none of the above statements can be observed in the invention.

5- In addition to using in an automobile, my designed lock can be used in motor vehicles and even installing it on a bicycle with the same high safety factor with a slight change in the appearance of the pedal lock, while such a thing is not possible in this design performed.

autonomous fingerprint pedal lock with capability to record images and equipped with electric shock system , The technical background of pedal lock designed is in the field of electrical engineering and security. In the previous technical knowledge, key pedal locks with a high safety factor were invented, but their safety factor decreased very soon using tricks to steal these types of locks or problems such as forgetting or breaking the key or cutting the pedal lock shackle, and people's attention was drawn to intelligent electronic locks that an anti-theft intelligent pedal lock with a high safety factor and fingerprint recording and processing capabilities were designed and manufactured as quickly as possible with the advancement of industry and technology, which could be a good alternative for key pedal locks and associated with easy to use. The applications of anti-theft intelligent pedal lock are in the closing of the car pedal and, with a slight change, in the apparent structure of lock used for the motorcycles and bicycles.

With the advancement of industry and technology, password and key pedal locks and with a high safety factor were invented and were able to allocate a special place in the industry, but the use of tricks used to open and close the locks reduced their safety factor soon, and humans always think that intelligent electronic pedal locks with better capability and higher safety factors can be a good alternative to password and key locks. The technical problem that is common in password and key pedal locks is that their safety factor is very low and their most fundamental problem is breaking or forgetting the key or password of lock. The purpose of the invention of intelligent electronic pedal locks is to upgrade the safety factor of locks and to eliminate problems such as breaking or forgetting the keys and making it possible to advance in science and technology electronics.

Expression of Invention Objectives :

1-The purpose of the invention of pedal lock designed is that, by removing the key and putting the fingerprint sensor, due to the improvement of the safety factor and the speed of unfastening and fastening the lock to reduce the performance error, as well as placing the electric shock system and image recording system inside the pedal lock circuit system, as well as by designing an alarm system independent of pedal lock and a system disrupting the AUTOMOBILE ECU performance, all of these systems will be activated when stealing occurs and the connection between them is carried out for wireless, and it does not allow the robber to have enough time to launch and steal AUTOMOBILE that the restoration of all these actions to normal mode is only possible by the mobile application.

2- Another purpose of the invention is that, by designing an application made for mobile, we can talk about the information of pedal lock electronic system such as battery charge level and limiting users using the lock by admin, as well as finding full awareness during the stealing of AUTOMOBILE and locating and sending an alert message, such as text message or telephone call with the owner of the AUTOMOBILE, and most importantly resetting the pedal lock electronic circuit in case of system performance problems or resetting the alarm system independent of pedal lock and the system disrupting the AUTOMOBILE ECU performance.

The solution provided to the existing technical problem with the old and key locks is that the use of electronic pedal locks with capability to record and process fingerprint can change the locking industry and increase the safety factor and make it easy to use.

In general, the operation of the circuit is as follows:

A fingerprint sensor is placed in the circuit to detect fingerprints of the user and when the fingerprint is properly detected, the DC motor is activated and the lock is opened, but if the fingerprint was incorrectly entered more than 3 times, or the pedal lock shackle were broken or cut, according to the planning done and the embedding of image recording camera and electric shock system in the circuit, the lock allows the camera to initially record and capture the image of the intended person in memory placed on the board and send it through the serial communication to the application designed for mobile and the electric shock system is activated in the unit and the pedal lock body becomes shocker and the thief is also electrocuted and the electric shock system is cut off after 5 minutes and the lock body restores to its original state as well as, buzzer is activated at the same time and the lock circuit sends a frequency to receiver of the lock siren remote system from the pedal lock through the transmitter placed on the pedal lock circuit and the alarm system starts to siren with an audible and loud voice and sends a message through the WIFI module to the car ECU system at the same time and completely disables the car's power system and prevents the car from starting that resetting and restoring to the initial state of ECU system is only possible through the mobile app, otherwise ECU system cannot be manipulated anyway. Because this circuit works in a certain temperature range, a heat and humidity sensor is placed in the circuit for the user’s knowledge of ambient temperature. A RTC module is placed in the circuit to record and report the time and date of the person using the lock. To set up the circuit, a rechargeable lithium polymer battery is also embedded in the circuit. This capability exists in the circuit that when pedal lock was not with us or was not available for any reason, the car's power system can be completely cut off and the car is no longer able to move through the mobile app, which plays the role of wireless hidden switch for us, and the vehicle restart is possible only by resetting the car's ECU system and restoring to its original state through the mobile app.

1- Easy and quick operation of pedal lock unfastening and fastening because of the key removal and placement of capacitive fingerprint sensor instead due to the high speed of fingerprint image processing and reduction of performance error during the lock unfastening and fastening.

2- High safety factor during the theft due to wireless transmission of all connections between the electronic system of pedal lock and the alarms system independent of pedal lock and the system disrupting automobile ECU's performance.

3- Being stainless and styling, as well as tightness of pedal lock body and its shackle due to the use of existing alloys.

DETAILED DESCRIPTION OF THE DRAWINGS

With the practical design of the circuit made, it can be mass-produced, and taken advantage of in the locking industry.

In the following detailed description, a reference is made to the accompanying drawings that form a part hereof, and in which the specific embodiments that may be practiced is shown by way of illustration. The embodiments are described in sufficient detail to enable those skilled in the art to practice the embodiments and it is to be understood that the logical, mechanical and other changes may be made without departing from the scope of the embodiments. The following detailed description is therefore not to be taken in a limiting sense.

FIG. 1 expresses the technical drawing of the pedal lock electronic circuit where in , 1 3.7 Volt Lithium Polymer Battery (LiPo Battery) is responsible for storing the system's internal application settings, setting up the DC motor when unlocking and feeding internal components (such as microcontroller and fingerprint scanner). It has the capacity of 1200 mAh with frequent charging capability. 2 Charger module and battery saver (lipo Protector), When charging the battery by the USB input port, this module monitors and controls the flow rate. To prevent damage to the battery when the voltage is applied improperly, the module automatically disconnects the power supply, and protects the battery against abrupt changes of current in the circuit. 3 Battery Power Meter Module (Power Gauge) , This module measures the amount of battery power at the reading moment by the microcontroller precisely. When connecting mobile app, the information recorded is displayed as a percentage. 4 Battery Charger Module (Battery Charger) , This module is responsible for voltage stabilization and control of the current required to charge the battery. When charge of the battery was finished, it can be recharged by connecting the charger port (located at the bottom part of the lock body). 5 Diode Bridge (Bridge) , In the design of input power supply lock, a 4-pin magnetic connector is used to charge the battery. In the event of a power cable connection in the wrong direction, a diode bridge is used to neutralize the input polarity, which allows battery charging in both directions. 6 Voltage transducer 3.7 volts to 3.3 volts (3v3 regulator) , Some parts (including fingerprint scanners, Wi Fi modules, and time holders) are only launched by applying a voltage of 3.3 V, and applying higher voltages leads to the loss of these components and modules. This voltage regulator (voltage stabilizer) is used to prevent this event, and to apply the appropriate and necessary voltage and voltage for the parts. As the linear regulator is not used in the circuit design, there is no loss of energy and generally provides appropriate optimization for the circuit. 7 WIFI-ESP8266 Module , This multi-functional module includes microcontroller integrated circuit and WIFI connection in the form of an IC and is used as the main core of the lock circuit. The Wi-Fi connection capability of this module is used to send data (via the serial port) to the mobile application; as well as, the internal memory of this module is used as a microcontroller flash memory.

Note: The Bluetooth module can be also used instead of the WIFI module to perform this process in the lock circuit. This does not require an external microcontroller when using the ESP-32 module, but the use of modules such as HC-05 creates the need for using an external microcontroller (such as ATMEGA328p in the circuit).

8 RTC Module: (Module Holding the Device Time) , This module is used to record the current time and date of the circuit; in addition, when the user uses the system, report of person using the lock (including the exact date and time of use) is recorded in the device memory. This information can be accessed and used when the mobile app is connected. 9 LED (RGB) , To display different states of lock (off, on, ready to connect, logged in, logged off), a super-bright three-color LED with various color output capabilities has been used that the user can get information from the current status of lock by reading the color displayed. To display the actions taken, such as correct or incorrect detection of fingerprints or the WIFI connection of the device to the mobile, different colors are used in the circuit.10 BUZZER , A small buzzer has been used for tasks such as the response to a WIFI connection, confirmation of unlocking, and alarm during the lock theft in the internal circuit of lock.(See item 15 for more information). 11 Temperature and humidity sensor (TEMPERATURE) , Because the designed lock is applicable to a certain temperature range, so a temperature and humidity sensor is intended to detect the temperature and humidity of the environment. Information of the sensor is also accessible by the mobile app.12 Fingerprint Sensor , The main piece opening the lock circuit is a fingerprint scanner (FPC-1075) that is used to detect the fingerprint of the person using the lock for opening and closing the lock. The sensor can store more than 200 fingerprints in its internal memory. To set up the lock and put it in standby mode, a micro-switch (push button) is placed under the sensor to remove the circuit lock from the standby mode, which is visible with the name of wake up in the technical drawing.13 Electric shock system (SHOCKER CIRCUIT) , An electric shock system is embedded in the circuit, which is activated when theft of lock is done, and the lock body and bracelet become the shocker and the thief is subject to electric shock.14 CAMERA , A camera is used in the circuit, which is activated when lock is unlocked and stores the user's image on the internal memory in order to display in future uses.In the case of lock theft, the thief's picture is taken and stored in the memory of SD card placed on the main board. Images are visible when connecting to the mobile app via the serial port.15 Anti-Theft System , An anti-theft system is designed in the shackle part of lock. In this design, one side of the shackle to short circuit GND in normal mode and its other side to one of the microcontroller bases and a pull-up resistor are connected. When the lock shackle is cut off, since the GND connection to the Sense pin is disconnected from the microcontroller, and the level of the input voltage is high through the resistance, and the part connected to the microcontroller is noticed by the cutting of shackle. At this time, the microcontroller sends a message to the alarm system and activates the siren and causes the escaping thief. Also, report of this performance is visible on the mobile app.16 FILTERING circuit , When the shocker system is activated, this system causes the creation of noise and disturbance in the circuit. Because the WIFI module has an operating frequency sensitive to the disturbance, the noise will cause the failure of it. Hence, a filtering circuit is embedded to prevent disruption with the WIFI connection and to stabilize the operation of lock circuit in the system.17 SIREN REMOTE , A lock siren remote system is designed, the transmitter part of which is placed on the main board and the receiver part is displayed in Fig. 2. By triggering the buzzer, the microcontroller sends the frequency to the receiver of the lock siren remote system circuit, using a transmitter placed on the lock circuit, and activates the lock siren remote system and runs away thief by creating high-power sound, which can also turn it off using the remote control or via the mobile app.18 MECHANICAL MOTOR , A 3-volt DC motor is placed in the circuit for opening and closing the lock that is activated by the detection of fingerprint accuracy and lock is opened.

FIG. 2 shows the technical drawing of the lock siren remote system circuit where in 19 12V DC Car Battery , The power supply of the lock siren remote system can be permanently and continuously operated in this way. 20 Three-cell (12v) rechargeable lithium polymer battery , The battery as a backup battery is embedded in the lock siren remote system that the car's battery as an alternative source of power prevents the failure of alarm system when the power is interrupted. 21 Battery Charger, By connecting to the car battery, the battery is constantly charging, and by placing the battery protector in the circuit when the battery is fully charged, the battery charging is automatically cut off to prevent damage to the battery. 22 Alarm System Receiver , This piece is responsible for receiving the activation code of the alarm from the lock and transmits the data between the two pieces, the transmitter part of which is on the lock circuit and its receiver inside the system circuit of the siren remote separated from the lock. 23 VOICE AMPLIFICATION MODULE , When the siren sounded, it amplifies the sound and generates high-power sound.24 Speaker, The siren sound can be heard through the alarm system.
