Abstract

Radio clocking-in system, in which a location code is coupled from a clocking-in point (ST) into a mobile radio device (MF) and is transmitted to a central station (Z) for display and documentation (DOK). The clocking-in point (ST) has, for example, an electronic location code generator component. Through simultaneous pressing of an actuation button (AT) and the speech button (T) of the radio device, acoustic coupling of the location code from a loudspeaker (LSP) of the clocking-in station (ST) to the microphone (MIK) of the radio device (MF) and transmission to the central station (Z) are performed. In a different embodiment, the clocking-in station (ST) comprises only one bar code strip which is read with a bar-code reader (L) and is coupled into the radio device (MF). <IMAGE>

Description

Radio time clock system

The invention relates to a radio time clock system according to the preamble of claim 1. Such a system is from prospectus no. EK-VKD 8 699 921 152 (041/5) known from Bosch.

A security guard who conducts a patrol and various In this known system, a handheld radio is used usual kind with you. This is for interacting with the puncture points with equipped with a manual control unit and additional logic. The stinging points exist from a wall box, which has a special coding key with a magnetic code contains. To "pierce" the coding key is taken from the wall box into a Reading device on the hand-held control unit of the radio device pushed in as far as it will go inserted and withdrawn again. The code of the key read and together with the identification of the handheld radio to a radio center transfer. In the headquarters there are facilities for display and documentation. This known system makes it possible to determine precisely and quickly which Expert is where and when. However, the lancing process is still quite cumbersome and time consuming.

The object of the invention is therefore to provide a further system of the initially specified type, which with comparable or: less effort a Relief of the lancing process results.

The invention is described in claim 1. The subclaims include advantageous embodiments of the invention.

The invention is explained in more detail below with reference to the figures.

FIG. 1A shows a first embodiment of the invention.

A block diagram for the associated puncture point ST is shown in FIG. 2. This embodiment has the advantage that any conventional mobile radio without any retrofitting or additions can be used. Operation by a security guard is extremely easy. The entire system can be made up of devices and components Programs are built.

The puncture point ST has a location code encoder module CODE, which a location code telegram when a release button AT is pressed via an NF amplifier NFV on a speaker LSP there. The telegram can be FSK or five-tone modulated. There are z. B. Identifier, the used in taxi radio networks will. The location code telegram is automatically repeated once or several times if necessary. The operator simultaneously presses the talk button T on their mobile radio device MF. If this device has an identification (man identification), this first becomes Central Z transmitted and only then released the microphone MIK. Now is on acoustically the location code telegram from the loudspeaker LSP of the piercing point ST coupled to the microphone MIK and transmitted from the mobile radio device MF to the center Z. Their stationary radio station OF receives the transmissions and forwards them a device for displaying and documenting DOK. It makes sense to send the head office if the reception is correct, an acoustic acknowledgment is sent to the mobile radio device MF. The power supply the lancing point can, for. B. be guaranteed via an accumulator, with the one Charge control indicator K is connected.

Transmission errors are almost impossible because the location code telegram is recorded at a distance of up to 1 meter. If the audio level is sufficient and high microphone sensitivity (as found in common handheld radios) the telegram is operated and displaced fully within the limits of the modulator any environmental noise.

FIG. 1B shows another embodiment of the invention.

The piercing point ST only consists of a barcode strip, which is attached so that it is protected against dirt and damage. The coupling on the mobile radio device MF takes place via a reading pen L. Its output signal is given to the audio input of the device; if necessary, an implementation in a telegram acceptable to the radio is sent. This embodiment is particularly cost-effective with a high number of stitch points.

Claims (3)

Claims radio time clock system, where a location code of a Lancing point (ST) coupled to a mobile radio device (MF) and from this to a Central (Z) is transferred which facilities for evaluation and documentation (DOK), characterized in that the coupling between the puncture point (ST) and mobile radio (MF) takes place acoustically or optically. 2. Radio time clock system according to claim 1, characterized in that the puncture point (ST) has an electronic location code transmitter module (CODE), a loudspeaker (LSP) and a release button (AT), and that the coupling of the Location codes from the loudspeaker (LSP) to the microphone (MIK) of the mobile radio device (MF) as well as the transfer of the location code takes place by pressing the talk button at the same time (T) of the mobile radio device (MF) and the trigger button (AT). 3. Radio - time clock system according to claim 1, characterized in that that the piercing point (ST) is a barcode strip, and that the coupling to the mobile radio (MF) via a barcode scanner (L).
