Description

Background of the invention

The invention relates to a device for identifying an object, collecting data and controlling work processes, comprising: a workwear part for carrying on the arm and / or on the hand, a receiving unit integrated in the workwear part, in particular an RFID antenna, for receiving signals from the Object and a reader for reading the signals received by the receiving unit.

Such a device is known for example from DE 10 2015 111 56 A1 RFID reading systems are used to identify objects (eg goods or containers for goods) and are used, among other things, to automate logistical movements. The objects are provided with an RFID transponder, which can be read by means of an RFID reader. The collected information is z. B. used to put the objects in the right storage racks.

DE 10 2015 111 56 A1 discloses a workwear unit comprising a wristband with an integrated control unit and a glove with an integrated RFID reader and an antenna, the reader being connectable to the control unit. The reader identifies workpieces and determines the position of the user. The glove includes sensors on the fingertips that serve as switches to activate the reading function of the reader. The control unit comprises a microcomputer, with the aid of which the antenna is controlled and data detected by the antenna are transmitted to a higher-level system. The information obtained is subjected to a plausibility check in order to give the user feedback.

Although a handy device is provided by the known workwear, which reduces the time required for data acquisition; However, the data recording and battery capacity are correspondingly low, so that a review of the collected data regarding prescribed processes, in particular logistical processes can only take place in connection with an external computer. Accordingly, the feedback can only be made if there is a data connection of workwear to the external computer. In the case of a missing connection to this external computer, there can be no immediate control and therefore no timely feedback. In addition, there is a risk that the user forgets to activate the reading function by means of the sensors. Both can lead to an increased error rate. Another problem is that to change the control unit at least the bracelet must be completely replaced. For reasons of hygiene, therefore, at least two of these bracelets with integrated control unit must be provided for each user.
