Abstract

the present invention provides a method of detecting that a shipping container has been tampered with by unlawful opening of its doors, and a method of ensuring that patrolmen on duty are both safe and are patrolling their appointed route. Tags which are activated to transmit a signal as a result of an activating unit being brought into proximity thereto, or separated therefrom, are used. In protecting a shipping container the tag forms part of a detector structure which stores and transmits data which data changes when the container doors are opened and closed. In protecting premises, the patrolman activates each tag as he passes it to cause signals to be transmitted back to a control room. This indicates that the patrolman is moving from tag to tag in accordance with his schedule.

Claims

1. A method of enhancing security which comprises distributing tags throughout an area to be protected, each tag transmitting an identification signal, bringing a tag reader into said area, the reader picking up the signals transmitted by the tags, and downloading from the reader to a remote location the signals picked up by the reader from the tags.

2. A method as claimed in claim 1, wherein the tags transmit their identification signals at radio frequency.

3. A method as claimed in claim 1, wherein the reader transmits to the remote location at radio frequency.

4. A method as claimed in claim 1, wherein the signal transmitted by each tag includes data indicative of the status of the tag.

5. A method as claimed in claim 4, wherein the status indicating data transmitted is compared with stored data and a determination made as to whether there has been a change in the status of the tag.

6. A method as claimed in claim 1, wherein the reader is carried by a patrolman patrolling said area, the signal from each tag which the patrolman passes being picked up by the reader and transmitted to said remote location whereby the progress of the patrolman is tracked.

7. A method as claimed in claim 4, wherein said area is one having shipping containers therein and the tags are fitted to the containers, said data changing upon a door of the container to which the tag is fitted being opened whereby unauthorized door opening can be detected when the signal from that tag is read.

8. A method of determining whether a door of a shipping container has been opened, the method comprising applying a tag to one component of a shipping container, there being a tag operating means which moves with another component of the shipping container, said components being ones that move relatively to one another during opening of said door of the container, storing a signal on said tag as said components move together on door closing, changing said stored signal upon said tag and its operating means being separated during door opening, downloading the signal stored in the tag at the time the door is lawfully closed, and accessing said stored signal on the tag before the door is lawfully opened to verify that said signal has not changed due to unlawful door opening.

9. A method as claimed in claim 8 and including the step of applying a tag operating device to the other component of the container.

10. A method as claimed in claim 9 and which comprises the steps of fitting said tag or device to a handle constituting said one of said components, said handle being moved to unlock the container, and fitting the device or tag to a further component with respect to which said one component moves during opening.

11. A method as claimed in claim 9, wherein said tag and device are fitted one to said door and one to the frame of the container so that the device and tag are separated as the container door is opened.

12. A method as claimed in claim 8 and including the step of transmitting, at timed intervals and at radio frequency, the signal stored in the tag.

13. A method as claimed in claim 12, and including the further step of storing a unique tag identification signal in the tag, and transmitting, at timed intervals and a radio frequency, the unique identification signal stored in the tag.

14. A method of monitoring a patrolman'"'"'s progress which method comprises distributing tags along the patrolman'"'"'s route, each tag transmitting a unique identification signal, providing the patrolman with a reader for receiving said identification signals upon any of the tags and said reader being brought into sufficiently close proximity, and transmitting the tag identification signals picked up by the reader to a control room thereby to permit the patrolman'"'"'s progress from tag-to-tag to be monitored.
