Abstract
Abstract of Disclosure Method and arrangement for operating a communication system for communication between a central station (10) and one or a plurality or remote objects (20 to 25), as well as such an object, wherein at least one object is operated in a battery saving mode in which it is switched alternatively between a wake period for conducting communication between the object and the central station and a sleep period in which communication is inactive. Each object is designated a predetermined first time (t0) and a time interval (Dt), wherein each object initiates the wake periods at times t0+n (Dt) with n=0, 1, 2, ... and wherein the time interval is longer than the wake period.
Claims16
A method for operating a communication system for communication between a central station and a plurality of remote objects, the method comprising:
- operating said objects in a battery saving mode in which an object is switched alternately between a wake period for conducting communication between the object and the central station and a sleep period in which communication is inactive, each of the objects being designated a predetermined first time (t0) and a predetermined time interval (Dt), for initiating the wake periods at times t0 + n (Dt), where n equals increasing integer numbers beginning from zero.
An arrangement for operating a communication system for communication between a central station and a plurality of remote objects, the arrangement comprising:
- a control unit means for operating power consuming electric and/or electronic devices in a battery saving mode in which said devices are alternately switched between a wake period for conducting communication between an object and a central station and a sleep period in which communication is inactive and for initiating the wake periods at times t0 + n (Dt), wherein n equals increasing integer numbers beginning from zero, wherein t0 is a designated and predetermined first time, and wherein Dt is a predetermined time interval.
A computer program comprising computer program code run on a programmable microprocessor means for operating a communication system for communication between a central station and a plurality of remote objects by operating the objects in a battery saving mode in which an object is switched alternately between a wake period for conducting communication between the object and the central station and a sleep period in which communication is inactive, each of the objects being designated a predetermined first time (t0) and a predetermined time interval (Dt), for initiating the wake periods at times t0 + n (Dt), where n equals increasing integer numbers beginning from zero when the computer program code is run on the programmable microprocessor means.
A computer program product stored on a computer usable medium, comprising:
- computer program code means run on a programmable microprocessor means for operating a communication system for communication between a central station and a plurality of remote objects by operating the objects in a battery saving mode in which an object is switched alternately between a wake period for conducting communication between the object and the central station and a sleep period in which communication is inactive, each of the objects being designated a predetermined first time (t0) and a predetermined time interval (Dt), for initiating the wake periods at times t0 + n (Dt), where n equals increasing integer numbers beginning from zero when loaded into internal memory of the programmable microprocessor means.
A method for operating a communication system for communication between a central station and a plurality of remote objects, the method comprising:
- operating a system of a plurality of objects, said objects including at least one remotely traveling vehicle that carries electricity consuming devices on-board, in at least two modes including (1) a battery saving mode in which each of the plurality of object is switched alternately between a wake period during which communications are conducted between the object and a central station and (2) a sleep mode in which communication is inactive;
- and
- designating to each of the objects a predetermined first time (t0) and a predetermined time interval (Dt) for initiating the wake periods at regular intervals.
