Systems and methods to prevent hot-wiring of electronic gun racks
A system includes a controller in communication with a transmission device. The system further includes a gun rack that includes a locking mechanism. The controller is configured to release the locking mechanism in response to receiving, from the transmission device via modulation on a power wire that powers the controller, a pattern that corresponds to a predetermined pattern.
1. A system comprising:
an electronic gun rack comprising a controller and a solenoid;
a signal generator that is distinct from the gun rack and is configured to couple to a vehicle power source and configured to generate a pattern;
a first wire coupled between the electronic gun rack and the signal generator, the signal generator configured, upon activation, to send both a direct current voltage and the pattern to the electronic gun rack via the first wire coupled between the electronic gun rack and the signal generator that is distinct from the gun rack; and
a second wire coupled between the electronic gun rack and the signal generator, the second wire providing a ground reference to the electronic gun rack.
2. The system of claim 1 , wherein the controller is positioned within a tamper-resistant container.
3. The system of claim 1 , wherein the direct current voltage is a 12-volt drive voltage.
4. The system of claim 1 , further comprising:
a power storage device configured to store electrical energy from the direct current voltage and provide the stored electrical energy to power to the controller.
5. The system of claim 1 , wherein the signal generator is configured to maintain the direct current voltage for a predetermined duration of time.
6. The system of claim 1 , wherein the signal generator sends the pattern to the electronic gun rack by modulating the direct current voltage.
7. The system of claim 1 , wherein the controller includes a demodulator to demodulate the direct current voltage to retrieve the pattern.
8. The system of claim 1 , wherein the solenoid is configured to unlock a locking mechanism in response to the direct current voltage and in response to the pattern corresponding to a predetermined pattern.
9. The system of claim 1 , wherein the pattern includes an analog frequency pattern, a digital coded pattern, or a combination thereof.
10. The system of claim 1 , wherein the controller is further configured to monitor an electrical characteristic of the first wire and to detect whether the wire is severed based on changes to the electrical characteristic.
11. A vehicle-based weapon retention system comprising:
an electronic gun rack configured to be mounted within a vehicle and comprising a controller and a solenoid;
a signal generator configured to be mounted in the vehicle and configured to generate a pattern; and
a single power wire coupled between the electronic gun rack and the signal generator, the signal generator configured, upon activation, to modulate a power signal on the single power wire to encode a pattern therein and to send both the power signal and the pattern to the electronic gun rack via the single power wire.
12. The system of claim 11 , further comprising:
a ground wire coupled between the electronic gun rack and the signal generator.
13. The system of claim 11 , further comprising:
a tamper-resistant container enclosing the controller and the solenoid.
14. The system of claim 11 , wherein the power signal is a 12-volt drive voltage.
15. The system of claim 11 , further comprising:
a capacitor configured to store electrical energy from the power signal and to provide the stored electrical energy to power to the controller.
16. The system of claim 11 , wherein the signal generator is configured to maintain the power signal for a predetermined duration of time.
17. The system of claim 11 , wherein the controller includes a demodulator to demodulate the power signal to retrieve the pattern.
18. The system of claim 11 , wherein the solenoid is configured to unlock a locking mechanism in response to the power signal and in response to the pattern corresponding to a predetermined pattern.
19. The system of claim 11 , wherein the pattern includes an analog frequency pattern, a digital coded pattern, or a combination thereof.
20. The system of claim 11 , wherein the controller is further configured to monitor an electrical characteristic of the power wire and to detect whether the wire is severed based on changes to the electrical characteristic.
