BE1015702A6 - Parking brake unlocking system for trailer, has unlocking unit that sends electrical current to circuits to open solenoid valves after identifying authorized person, where valves are opened to unlock parking brake - Google Patents

Abstract

The system has an unlocking unit (8) sending an electrical current to circuits (9, 10) to open solenoid valves (11, 12), after identifying the authorized person. The unlocking unit receives information and a signal from a unit (15) or a processor (6). The solenoid valves are opened to unlock a parking brake. The units, processor, circuits, and valves are placed in a hard resin. The unit (15) communicates with the authorized person through a code entered on a keyboard, by presentation of a magnetic badge, through a radio signal transmitted from a remote control, through a signal transmitted from a GSM or through a signal transmitted via satellites from a central control. The processor analyze information, received by digital fingerprint sensors (1, 2), of finger (5) of the authorized person.

   Trailer park brake release device, operating either by code, magnetic badge, radio signal, GSM signal, satellite signal or by fingerprint recognition of the authorized person.



   DESCRIPTION The locking device of the brake system is contained in the housing 3. After analyzing the information received, the unlocking unit 8 will send an electric current in the circuits 9 & 10, opening the solenoid valves 11 & 12.



  The unlocking unit receives information and signals, namely: # of the unit 15 which communicates with the authorized person by code formed on a keyboard, by presentation of a magnetic badge, by a radio signal transmitted from a remote control, by signal sent from a GSM or by signal transmitted via satellites, from a central control.



     Processor # 6, embedded which analyzes the information collected by the fingerprint sensor 1 & 2, from the finger
5, of the authorized person.



   The image of the imprints or the capacitive effect generated by the circulation of blood in the fingerprints of the authorized person is compared to the memories at 7 and if the person is recognized, the unlocking unit will allow the opening of solenoid valves as explained above, and therefore the unlocking of park brakes.



   All the elements described above and contained in the housing 3 are embedded in a hard resin, preventing access to wiring. In this way, any attempt to intrude into the system is made impossible.



   On the other hand, the principle has been studied so as to keep the brakes locked if there is destruction of one of the elements contained in the brain box.

   INTRODUCTION This invention relates to the anti-theft safety of trailers when they are detached from their tractor.



  There are known devices for holding trailers in place, in particular by blocking the mooring pin preventing the attachment of a tractor.



  The present invention of which I am the author, consists in the impossibility of unlocking park brakes by someone other than the authorized one. It consists of a brain box that identifies and gives permission to unlock. It uses a high-tech electronic device using the most advanced techniques today Identification of the authorized person can be achieved in several ways, either - - by a code formed on a keyboard affixed to the brain housing, by passing a magnetic badge affixed to the brain case, by transmitting a signal encoded by a radio remote control, by receiving a signal transmitted from a GSM to the brain box,

   - by receiving a signal transmitted via satellites to the brain box - by recognizing the image of the fingerprints of the authorized person, when placing a finger on a sensor, - by the recognition of the capacitive effect caused by the circulation of blood in the internal fingerprints of the authorized person, when he puts his finger on a sensor.



  The invention will be better understood with reference to FIG. 1 and the attached description


    

Claims (7)

 1. Unblocking trailer park brakes detached from their tractor by identifying the authorized person with a secret code formed on a keyboard affixed to the brain box. 2. Release of trailer park brakes detached from their tractor by the identification of the authorized person, whose identification system is a magnetic badge slipped into a reader affixed to the brain case. 3. Release of trailer park brakes detached from their tractor by the identification of the authorized person identified by a proximity badge or a remote control transmitting a coded radio signal. 4. Release of trailer park brakes detached from their tractor by identifying the authorized person whose identification is made using a code transmitted to the brain box using a GSM. 5. Release of trailer park brakes detached from their tractor by the identification of the authorized person whose identification is carried out using a coded signal transmitted to the brain box using the satellites, at the start a control center. 6. Release of trailer park brakes detached from their tractor by the identification of the authorized person by the recognition of the image of the fingerprints, previously stored in the system. 7. Release of trailer park brakes detached from their tractor by the identification of the person authorized by the recognition of the capacitive effect generated by the blood circulation in the internal imprints of a finger and previously stored in the system.
