DE202010011660U1 - RFID tag controlled universal power plug to equip portable electrical appliances with a programmable switch identification device - Google Patents

Abstract

RFID tag controlled universal power plug for equipment portable electrical appliances with a programmable switch identification device characterized in that an integrated electronics in conjunction with a detected in the detection area code card, the socket unlocks when this code is recognized in the authorization memory of the electronics.

Description

State of the art

The electrical connection more mobile Electrical appliances with the electricity grid over flexible connection cable is usually made by corresponding standard socket connections different Design type. It is well known in the art that in the cavity of the connected plug also directly switching devices different Art be integrated. In particular, mechanical rocker or Toggle switch, remote controllable switch and electronic Dimmer as well as various protective relay versions known. These known Switches can be operated by anyone and therefore do not provide protection against unauthorized activation of the connected to the plug Equipment. In general practice, however, there are cases in which and security reasons It is not allowed for anyone to connect the connected electrical appliances without enable the appropriate authorization. There are also in these cases known solutions, by using key switches in the outlet circuits or by fixed switch-on codes in the devices directly, so-called parental controls, prevent unauthorized use can.

Object of the invention

Of the The invention is based on the idea to create a possibility People accessing a device to allow others to exclude, but in turn, rights have other personalized electronic devices in the same workspace to use.

The solution for that is the integration of an intelligent switching device in the interior the plug housing, so that only authorized persons have access to it the connected device to have. By using the device-neutral plug As an intelligent switching element, it is possible by exchange a normal power plug against the intelligent switching plug according to the invention any Eltelrogerät to retrofit with an individual switching device.

The Switching is wireless through use of the state of the art belonging RFID technology implemented. The authorized persons are in possession of suitable RFID tags different Design type. The authorization for the respective connector and thus also for later use of the connected device, done preparatory by approach a "learning card", which the internal plug electronics converted into the required learning readiness. The next now in the vicinity led of the plug RFID card is used as switch authorization in the plug electronics permanently saved.

Description of an embodiment

In a plastic housing ( 1 ) are located at the bottom according to the structural design of the respective connection system, the plug contacts ( 2 ) for the intended introduction to the current-carrying socket. The contacting of a flexible cable ( 5 ) to the power supply of the connected electrical device is carried out by releasable screw or clamp connection ( 4 ) also in the interior of the connector housing. The electronics box ( 8th ) as part of the invention includes the code memory for the switching permissions and the communication unit for the wireless bidirectional connection to the externally approximated code card. The data communication takes place via a transmitting-receiving coil ( 7 ). The respective switching state is 2 as an optical LED signal ( 6 ) is displayed. By operating the service switch not accessible under operating conditions ( 9 ) can be made by an administrator certain preferences. For practical use, the intelligent plug is introduced in a known manner in the power socket. The electronics box ( 8th ) has an automatic permanent memory function, which always activates the same switching state as it was activated before the respective mains disconnection when reinserting the plug after previous mains disconnection. If now in the ready state, the authorized person their individual code card ( 10 ) brings in the vicinity of the plug, the opposite switching state is triggered. In order to extend the circle of persons with switching authority, the so-called "learning card" ( 11 ) brought near the plug. This is the electronics box ( 8th ) temporarily in a learning and memory state in which they receive the recognized code of the subsequently approached new user card ( 10 ) adds to the circle of entitled persons.
