1. A container, comprising:
- a container body including a container frame with an open side, and a door unit for closing and opening said open side of said container frame; and
an anti-theft system includinga detecting device that is mounted on said container body, and that includes first and second detecting units each capable of signal transmission and reception, said first detecting unit being operable so as to transmit a first signal for reception by said second detecting unit, said second detecting unit being operable so as to transmit a second signal for reception by said first detecting unit in response to the first signal received from said first detecting unit when said door unit closes said open side of said container frame,a processing unit that is coupled electrically to said first detecting unit, and that monitors reception of the second signal by said first detecting unit and that controls transmission of the first signal by said first detecting unit, andan alarm unit that is coupled electrically to and that is controlled by said processing unit to generate an alarm signal upon detection by said processing unit of irregularity in reception of the second signal by said first detecting unit.

Abstract
An anti-theft system includes a detecting device, a processing unit, and an alarm unit. The detecting device includes a first detecting unit that is operable so as to transmit a first signal, and a second detecting unit that transmits a second signal to the first detecting unit in response to the first signal. The processing unit verifies the second signal, and enables the first detecting unit to continue to transmit the first signal upon successful verification of the second signal. The alarm unit generates an alarm signal upon unsuccessful verification of the second signal. A container that is safeguarded by the anti-theft system is also disclosed.

13. An anti-theft system for a container body that includes a container frame with an open side, and a door unit for closing and opening the open side of the container frame, said anti-theft system comprising:
-
a detecting device adapted for mounting on the container body, said detecting device including first and second detecting units each capable of signal transmission and reception, said first detecting unit being operable so as to transmit a first signal for reception by said second detecting unit, said second detecting unit being operable so as to transmit a second signal for reception by said first detecting unit in response to the first signal received from said first detecting unit when the door unit closes the open side of the container frame; a processing unit coupled electrically to said first detecting unit, said processing unit monitoring reception of the second signal by said first detecting unit and controlling transmission of the first signal by said first detecting unit; and an alarm unit coupled electrically to and controlled by said processing unit to generate an alarm signal upon detection by said processing unit of irregularity in reception of the second signal by said first detecting unit.
