Abstract

The invention relates to a system for providing a combined monitoring over a toll-container sealing, weighing-container sealing, or border crossing-container sealing, which comprises: (a) a plurality of combined toll-seal, weighing-seal or border crossing-seal interrogators, which are mounted along highways, said interrogators transmitting a same interrogating signal in a same standardized communication protocol and at the same operating frequencies, by all interrogators; (b) a plurality of toll, weighing, or border crossing, whichever is the case, transponders which are installed in vehicles, and a plurality of container sealing transponders which are installed in containers, said sealing transponders by receiving interrogation signal transmit a sealing response signal which is distinct from corresponding toll, weighing, or border crossing response signals transmitted by toll, weighing, or border crossing transponders; (c) decoding means within each interrogator for receiving and decoding response signals, and for separating response signals coming from sealing transponders from those coming from toll, weighing, or border crossing transponders, whichever is the case; and (d) an analyzing unit within each interrogator for analyzing the status of each decoded response signal coming from a sealing transponder, and for transmitting a status of the sealing transponder, as included in the decoded signal, or the decoded signal itself to a control center.

Claims

1. A system for providing a combined monitoring over a toll-container sealing, weighing-container sealing, or border crossing-container sealing, which comprises:

a plurality of combined toll-seal, weighing-seal or border crossing-seal interrogators, which are mounted along highways, said interrogators all transmitting a same interrogating signal in a same standardized communication protocol and at the same operating frequencies;

a plurality of toll, weighing, or border crossing, whichever is the case, transponders which are installed in vehicles, and a plurality of container sealing transponders which are installed in containers, said sealing transponders by receiving an interrogation signal transmit a sealing response signal which is distinct from corresponding toll, weighing, or border crossing response signals transmitted by toll, weighing, or border crossing transponders;

decoding means within each interrogator for receiving and decoding response signals, and for separating response signals coming from sealing transponders from those coming from toll, weighing, or border crossing transponders, whichever is the case; and

an analyzing unit within each interrogator for analyzing the status of each decoded response signal coming from a sealing transponder, and for transmitting a status of the sealing transponder, as included in the decoded signal, or the decoded signal itself to a control center;

2. System according to claim 1, wherein the interrogators and each of the electronic seal transponders communicate by using a standardized protocol, which is commonly used by weighing, border crossing, or toll systems.

3. System according to claim 2, wherein the interrogators and each of the electronic seal transponders communicate by using an ASTMv6 protocol.

4. Method for performing combined toll-container sealing, weighing-container sealing, or border crossing-container sealing, comprising the steps of:

assigning in each container sealing transponder response signal a field which distinguishes the signal from a response signal of a toll transponder, weighing transponder or border crossing transponder, whichever is the case;

transmitting an interrogation signal from a combined toll-container sealing interrogator, weighing-container sealing interrogator, or border crossing-container sealing interrogator, whichever is the case;

upon receipt of a response signal at the interrogator, analyzing said field in order to determine whether the response signal comes from a container sealing transponder;

if, based on said analysis, it has been found the response signal comes from a container sealing transponder, processing it as such;

otherwise, processing the response signal as coming from toll transponder, weighing transponder, or border crossing-transponder, whichever is the case.
