Trailer locking system
First Claim
1. A trailer locking system for securing a trailer having a door and a braking system, said braking system having a brake line configured to pneumatically interconnect a supply of compressed air to one or more air-operated brakes on said trailer, said trailer locking system comprising:
- a power supply;
a brake lock device in operative communication with said braking system, said brake lock device configured to selectively place said brakes in a locked condition and prevent movement of said trailer;
a door lock device in operative communication with said door, said door lock device configured to selectively prevent the opening of said door when said door lock device is in a locked condition;
a controller unit connected to said power supply and in operative communication with said brake lock device and said door lock device, said controller unit having computer circuitry and componentry configured to control the operation of said brake lock device and said door lock device; and
a control mechanism in communication with said controller unit, said control mechanism configured to transmit operational instructions to said controller unit.

Abstract
A locking system having a brake lock device for automatically immobilizing trailers to prevent unauthorized movement of the trailer and a door lock device for automatically locking the doors to prevent unauthorized entry into the trailer. The brake lock device vents compressed air from the brake line through a control valve connected to a controller unit. A keypad, transmits operational instructions to the controller unit. The door lock device has an electromechanical device, such as a linear actuator, connected to the controller unit to engage a receptor in or on a tubular frame member of the trailer to prevent the opening of the trailer doors. A position switch indicates the door status so the controller unit can automatically engage the locking mechanism. A radio in the controller unit permits wireless communication to report status and to allow central command control over the entire trailer locking system.

21. A trailer locking system for securing a trailer having a door and a braking system, said braking system having a brake line configured to pneumatically interconnect a supply of compressed air to one or more air-operated brakes on said trailer, said trailer locking system comprising:
-
a brake lock device in operative communication with said braking system, said brake lock device configured to selectively place said brakes in a locked condition and prevent movement of said trailer, said brake lock device having a control valve pneumatically connected to said brake line, said control valve configured to open to allow compressed air from said brake line to vent to maintain said brakes in said locked condition and to close to prevent compressed air from venting to place said brakes in an unlocked condition;
a door lock device in operative communication with said door, said door lock device having an actuator configured to operatively actuate a locking member so as to selectively lock said door, said locking member configured to prevent the opening of said door when said door lock device is in said locked position;
a controller unit connected to a power supply and in operative communication with said control valve of said brake lock device and said door lock device, said controller unit having computer circuitry and componentry configured to control the operation of said brake lock device and said door lock device; and
a control mechanism in communication with said controller unit, said control mechanism configured to transmit operational instructions to said controller unit. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A trailer locking system for securing a trailer having a door and a braking system, said braking system having a brake line configured to pneumatically interconnect a supply of compressed air to one or more air-operated brakes on said trailer, said trailer having a frame comprising one or more tubular frame members, said trailer locking system comprising:
-
a brake lock device in operative communication with said braking system, said brake lock device configured to selectively place said brakes in a locked condition and prevent movement of said trailer, said brake lock device having a control valve pneumatically connected to said brake line and one or more pressure sensors operatively engaged with said control valve to measure the air pressure at said control valve, said control valve configured to open to allow compressed air from said brake line to vent to maintain said brakes in said locked condition and to close to prevent compressed air from venting to place said brakes in an unlocked condition;
a door lock device in operative communication with said door, said door lock device having an actuator configured to operatively actuate a locking member so as to selectively lock said door, said locking member configured to be slidably received in a receptor disposed in one of said one or more tubular frame members and cooperatively engaged therewith to prevent the opening of said door until an open command is received from said controller unit;
a controller unit connected to a power supply and in operative communication with said control valve of said brake lock device and said door lock device, said controller unit having computer circuitry and componentry configured to control the operation of said brake lock device and said door lock device;
a control mechanism in communication with said controller unit, said control mechanism configured to transmit operational instructions to said controller unit; and
a communication system for the transmission of signals across a wireless communication network, said communication system comprising a communication device operatively connected to said controller unit. - View Dependent Claims (32, 33, 34)
