1.1. Surveillance systems characterized by checking, on demand, the relative position and, if applicable, state parameters of selected objects of a mobile user and reporting their availability status.

Description

General problem and solution description

In everyday life, our attention is often distracted and entrained values are lost to us, eg. B. the mobile data storage in the computer of an Internet cafe can be forgotten, the keychain slips unnoticed in an armchair or even the bag with valuable content can be withdrawn unnoticed by a thief.

To avoid such losses, the portable monitoring system checks at adjustable intervals whether the position of the values marked with simple sensors changes relative to the user and warns them if the availability of the value objects is jeopardized.

System description and applications

• • einer kompakten Überwachungseinheit beim Benutzer (z. B. auch in Schmuckform) und
• • unterschiedliche, einfache Sensoren angebracht an den gekennzeichneten Objekten.

The portable surveillance system works by:

• • a compact monitoring unit at the user (eg also in jewelery form) and
• • different, simple sensors attached to the marked objects.

The user monitoring unit periodically transmits electromagnetic monitoring signals to the sensors registered in the system on the value objects and checks their electromagnetic response signal, its signal characteristics (eg, signal strength), as well as the data content encoded in the signal.

If the electromagnetic response signal of one of the sensors registered in the monitoring system differs from or even misses the reference signal at registration or at the previous test, the user will be notified accordingly.

The notification of the user takes place either visually, acoustically, mechanically (vibration) or by means of a combination of these signals in order to clearly transmit the warning effect depending on the environment.

After confirming a warning, the user can also suppress the notifications for selected sensors or values: partially, temporarily or completely, so as not to be disturbed in an undesirable manner, eg if the user has been warned. B. he has deliberately stored or removed individual objects marked with sensors.

The sensors are simple passive and / or active sensors, equipped with a wireless transmitting and receiving module, which are mounted by the user on the marked objects and automatically registered in the monitoring system.

In this case, for each of the sensors, the respective monitoring field is defined in the sensor registration, based on reference values of the electromagnetic response signal of a sensor relative to the monitoring unit at the user, based on the usual positions of the marked value object.

It can be used for different sensors on the objects, z. B. inductive sensors, as well as the commercial RFID sensors.

The relative monitoring field can be determined according to the peculiarities of the value object, by an appropriate choice of the attached sensor, depending on its size and the strength of its nominal response signal, z. B .:
An active sensor (with its own power supply) can, for. B. be attached to a bicycle that is parked outside the room in which the user usually resides, so as to ensure the monitoring of the object bike at a distance of several meters.
A passive sensor, attached z. B. on a mobile phone, a mobile data storage, a wallet or a credit card can be used in the meter range, so that the monitoring unit signals the user when the objects marked with such sensors are already removed at a short distance outside the Verfügbarbeitsweite of the user ,
Should it be z. B. come to the fact that the user has stayed away from a computer in which his designated memory module, the monitoring unit signals this clearly. Even if the user moves away from his tagged cell phone that he may forget, this distance is signaled to him.
A small passive sensor, with short signal range, can be used for small monitoring distances in the centimeter range.
So z. For example, if the monitoring unit is attached to the belt or at the pocket level, a small passive sensor attached to the zipper pull may be interrogated, and if the closure remains open for a fixed amount of time, the user would be warned considerately to avoid loss of personality.

With this means, the system can also check and warn the user as soon as z. As a child or a dog, the z. B. carries on a piece of clothing or jewelry, undesirably removed from the supervisor and thus could lose in a crowd.

• • zu prüfen ob man all die notwendigen persönlichen Objekte bei sich hat, bevor man einen Ort verlässt (z. B. die Wohnung oder ein besuchtes Lokal),
• • zur Prüfung der Verfügbarkeit der beim Einsatz benötigten Werkzeuge, bevor sich ein Techniker zu einer Dienstaufgabe begibt oder
• • zur Prüfung der Vollständigkeit der Einsatzausrüstung, bevor Sicherheitskräfte in einer Mission starten.

The portable monitoring system can check the availability of all the objects to be monitored automatically, time-controlled or position-controlled, but also at the user's request, and report this back. This function can be advantageous as a "system check" if the user wants to check promptly on an upcoming activity, if all his required objects are available, eg. B .:

• • to check if you have all the necessary personal items with you before leaving a place (eg the apartment or a visited place),
• • to check the availability of the tools needed during deployment, before a technician commits to a service assignment or
• • to check the completeness of the deployment equipment before security forces start in a mission.

• – den induktiv gemessenen Ladezustand eines Objektes mit Akku,
• – der kapazitiv gemessenen Mindestfüllgrad eines Flüssigkeitsbehälters,
• – den kapazitiv oder rezistiv gemessenen Sicherungszustand einer Waffe.

In this case, it is also possible case-related that the sensors attached to the value objects transmit current properties or state parameters of the marked objects, for. B .:

• - the inductively measured state of charge of an object with battery,
• The capacitively measured minimum filling level of a liquid container,
• - The capacitive or rezistiv measured security state of a weapon.

State of the art

• • die Überwachung der Waren im Handel (auch mit RFID-Sensoren),
• • die Überwachung von Straftätern mit elektronischen Fesseln oder
• • die GPS-Überwachung von Objekten (z. B. PKW oder auch Personen).

There are various monitoring systems on the market that issue warnings when objects leave a defined environment, such as For example:

• • the monitoring of goods in the trade (also with RFID sensors),
• • monitoring criminals with electronic restraints or
• • GPS monitoring of objects (eg cars or even persons).

However, such systems are controlled by a fixed, localized surveillance system and sometimes available only as a cost-based services such. B. GPS surveillance services.

On the other hand, there are also GPS tracking systems for appropriately marked, mostly large objects, the search area resolution, however, due to the technology is in the range of about 5 to 50 meters and are designed for use outside of buildings.

Another category of systems available on the market is to retrieve lost items equipped with an active sending and receiving unit. The search environment is usually on range of some rooms possible and their application is the search of objects that have been moved in a common environment.

The RFID platform developed for the merchandise management system also uses mobile readers that emit electromagnetic signals and evaluate the data content of the response signals, so that even without visual contact (as for barcode readers) data on goods in a defined environment (eg in the warehouse) and provide for a higher-level logistics system. However, they are not designed to monitor the relative distance to objects, but for the purpose of data collection.

comparison

However, a portable monitoring system that monitors the availability of mobile values, as illustrated in the description, is not yet known, although the benefit is unambiguous.

For a mobile surveillance system, the RFID platform can also be used as the basis for signal transmission. Another advantage when using the RFID platform would be that the electromagnetic signals used worldwide standardized and the sensors in different model variants due to the mass production are cheap, which can promote the worldwide use of their own monitoring system.
