DE19504493A1 - Wireless measurement data exchange method e.g. for remote measurement values - Google Patents

Abstract

The data exchange is carried out between spatially separated measurement or communication units and makes use of an existing digital telephone network. Equipment used includes a communication device (4), which can be a commercially available radiotelephone for the D- or E-networks. The actual measurement unit (20) is based on an analysis device (1), a measurement device, an environment monitoring station and/or a multi-parameter device.

Description

The invention relates to a method and an apparatus for wireless data exchange between spatially separated measuring and / or communication facilities.

Wireless data exchange via a radio link between a central query and control device and decentralized Measuring systems, especially on remote, difficult to access Locations or in mobile measuring devices without connection to the Fixed telephone network is known in principle. The disadvantage here when special transmitters / receivers are required that are on due to the low number of pieces, high production costs as well as cumbersome to use.

The invention seeks to remedy this.

The invention has for its object the manufacturing cost of the device for performing the method according to significantly reduce the preamble of claim 1 and the ease of use and data transmission security noticeably increase.

This object is achieved by the features of patent claim 1 solved, while the claims 2-9 devices for Implement the method according to the invention.

The invention enables wireless digital data transmission transfer between measuring systems or remote control of the same, especially from mobile environmental measuring stations, far from the Development through the telephone line network, on inexpensive Way if a high-frequency digital telephone network is available is available. This has been recently through that  D-Netz in Germany, while the E-Netz in the brisk Structure is understood. This is also the possibility created by means of a radio telephone or by means of a a modem or a computer equipped with a radio telephone to operate such environmental measuring systems from a distance, which otherwise most contain no controls.

Due to the proliferation of radio telephones in the youngest Past and the clear that this made possible Price reduction opens up an inexpensive way to wireless data transmission z. B. in the field of environmental protection Measuring technology.

The invention will now be described with reference to the drawing explained.

This shows a device which comprises at least one measuring device 20 , equipped with a remote data transmission interface 3 and a communication device 4 , and at least one separate communication device 4 for a generally accessible digital high-frequency telephone network. A commercially available radio telephone for the D or E network can serve as the communication device 4 . As a remote data transmission interface 3 , a commercially available standard product can be used, so that a separate technical acceptance test, as has been customary up to now, can be omitted.

The measuring device 20 consists of a measuring system 1 , z. B. an analysis device, a measuring device, an environmental monitor station and / or a multi-parameter device. The measuring device 20 is further preferably equipped with a control computer 2 and corresponding software for capturing and / or evaluating data from the measuring system 1 and / or for controlling and regulating the same. The control computer 2 communicates with the interface 3 for high-frequency digital radio data transmission via the communication device 4 .

The measuring device 20 can be installed in a vehicle, for example, and can thus be operated in a variable position.

The data generated by the measuring device 20 , digitized and high-frequency emitted data can be received by a communication device 4 and / or by a central device 10 . This preferably has a central computing system 5 with computer programs for collecting and / or evaluating the data transmitted by the measuring device 20 and / or for generating the control pulses required for remote control of the measuring system 1 , and via an interface 3 for high-frequency digital data transmission by means of communication device 4 .

In an optional embodiment, the communication of the central device 10 is not limited to that with a single measuring device 20 , which can optionally also be linked via the digital telephone network.

In a further embodiment, the central device 10 can optionally have an interface to the telephone line network 6 , e.g. B. with a modem or an ISDN card, to be connected to the fixed telephone network 7 .

At least one further portable communication device 4 can be provided in order to be able to query or operate the one measuring device 20 and / or the central device 10 from a distance.
