Description

The invention relates to a data acquisition device for implementation surveys and data processing in real time. The data capture device can display data on a screen and using a keyboard to record this information via a communication network to a remote computer terminal forward, which carries out the processing of the data. The device was specially designed to be compared to others Devices available on the market are the same or comparable To provide clear benefits.

There are currently numerous stationary or mobile data users known devices that are used to record data and then take them to a computer terminal transferred, which in turn evaluates the data and on this way new information is generated. All of these devices exhibit  a view screen with keyboard on, are over a specific electronic card and software controlled and are in housed in a thermoplastic housing.

As examples of the known devices mentioned above, the Data acquisition devices are listed, the beverages ver drive or during material control in factories or warehouses Find use, as well as other comparable devices. All Data acquisition devices can use a keyboard or through reading a bar code stores certain information, which then either through a direct connection a PC or, with the help of a modem, to a computer terminal be transferred, the processing of the data and the Creation of the results resulting from this information carries out.

All systems described and known to date have one concrete scope. The amount of information stored is always the same. It is not an external interaction possible and the devices can neither automatically with others, in a network connected peripheral devices occur, still a multi-sectoral and multi-conceptual Information offering that a variety of quantitative, satisfies qualitative or survey-specific questions, to offer.

In general, the devices known to date were used for a very specific use and as mobile devices wraps, making them difficult to change conditions can be fitted, such as in the case of a fastening to the seats of an event location where it pays off stop rich people to get an opinion.

The data acquisition device, which is the subject of the present Invention is, has a new arrangement of elements,  in such a way that it itself becomes a remote computer terminal becomes. This enables opinion polls to be conducted in real time and with a for the interaction between the user and the one on the Software displayed on the screen leads. Overall, it can be said that the device is out Basic elements of a largely known technology, but has a configuration of these elements that makes it a remote computer terminal that is simple Installation and handling as well as great connectivity net. This makes it unique compared to other data recording devices currently used for comparable purposes on the Market can be found.

To achieve this goal, the data acquisition device is included a visual screen for displaying the messages and also has an ergonomic keyboard, the one Entry as on a computer terminal enables, via a specially designed electronic card with its own Software and standard communication protocols. The stock parts are in a housing made of thermoplastic material housed, which has the required properties owns. The device described here can be Easy to install and remove systems on any external element and can also be attached to an internal one Network of the building can be connected, which is possible is connected to an external network, so that a Connection for the interaction between the devices and one internal or external remote computer center can; the connection to the data acquisition device can both with and without cables. With wireless off the devices are designed in such a way that they compliance guidelines.

Due to the above, data acquisition is the link between opinion studies and the per  those who express their opinions act as what the Companies, in turn, have the opportunity to do so, as desired conduct all types of surveys, a service sub take for surveys or just take theirs organize your own opinion polls.

In view of the presented invention, it is fundamental legendary meaning that the device has an interactive user surface and has all the necessary components are so that a person can express their opinion on various topics can express a quantitative and qualitative view, and so messages or pictures appear on the screen can; it can be used in a wide variety of places where optional audiovisual media may be available so that consequently the device must work clearly self-sufficient to this Conduct surveys.

The invention is based on a preferred embodiment further explained and described. Show it

Fig. 1 is a perspective view of the data acquisition device, wherein the most important components are shown pulled apart, and

Fig. 2 is a front view of the inner element of the data acquisition device.

The data acquisition device for carrying out surveys and for data processing in real time has an outer closure housing 1 and a fastening device 2 . Inside, a screen 3 is shown for displaying messages or questions. Keyboards 4 and 5 are used for functional interaction. An electronic card 6 is also provided.

The end housing has recesses 7 on the front through which the keyboard 4 is accessible from the outside. The keyboard 4 can be tilted forward using an electric motor 8 ge. A cutout 9 enables the keyboard 5 to be operated . A recess 10 gives a free top view of the screen 3 .

A battery 11 can be attached to the end housing 1 in order to be able to use the data acquisition device even when it is not directly connected to a power supply with an electrical cable. The data acquisition device has a microphone 12 , an output connection 13 for a headphone and an output 14 in order to produce a good infrared or high-frequency connection. At the lower end of the end housing 1 , projections are provided in which interfaces 15 and 16 are provided for connection to a closed or open internal or external network.

The screen 3 can display both dynamic and static messages and images. It is an LCD screen that can be optionally illuminated and can produce any color or combination of colors.

The keyboard 4 is alphanumeric and enables the transmission of both word expressions and numerical expressions, and there is also the advantageous possibility of including the Braille system. The keyboard 4 can be reprogrammed and configured according to the interests and needs of each application. It can be pivoted with the help of the electric motor 8 , as described above, and can also be illuminated if desired, in order to enable the keys to be identified even in poorly lit locations.

The keyboard 5 has keys for complete or partial deletion of the entered text, a correspondingly marked key for transmitting information and a warning buzzer for error messages or key presses, which also has the option of storing melodies that the sponsor of the event or Characterize rooms in which the data acquisition device is located. An undefined number of function keys is available for assignment, whereby these function keys can be configured in solidarity with the alphanumeric keyboard or independently of it.

The electronic card 6 mainly represents a carrier for a microprocessor 17 and for storage units RAM 18 and ROM 19 , the latter having the original operating software and standard communication software and furthermore being equipped with processors for video / audio and for microphones 20 are. The electronic card 6 is also equipped for controlling the interfaces 15 and 16 , the output connector 13 for the headphones, the output 14 for a data receiving unit for infrared rays or high-frequency waves, and the microphone 12 for multimedia applications.

The end housing 1 , the fastening device 2 and the cabling meet the requirements for the fulfillment of all applicable provisions with regard to the various venues, which are logically public in nature and where the data acquisition device described here is used for the purpose of opinion polling with an indefinite number of people in real time will be required.
