Problems solved by technology

Although the above can be achieved by employing standard protocols and corresponding hardware, the chosen protocol then limits the number of possible addressable devices, since the address space of the chosen protocol does not allow the definition of a sufficient number of unique addresses and thus device identifier for

Embodiment Construction

[0027] Figure 1A A schematic diagram of a data collection system according to an embodiment of the present invention is shown. The data collection system includes a central entity, a data collection device, and a data collection device, and implements data frame transmission. Specifically, the data collection system according to this embodiment comprises a central entity 10, a data collection device in the form of one or more data collection units 30, 30', and a data collection device in the form of one or more data collection units 40, 40' device. The central entity 10 can exchange data with the data collection units 30, 30' using some kind of network or network system 20, which can include the Internet, one or more corporate networks, and / or public networks such as telephone or mobile communication network.

[0028] As an example, a first link 91 couples the central entity 10 to the Internet 20 and a second link 92 couples at least one data collection unit 30 to the Intern...

Abstract

A data frame is transmitted from a source device to a target device, wherein the source device and the target device use a protocol defining a request command frame for polling pending data. The method comprises the steps of: obtaining data to be transmitted to the target device in the source device; generating, at the target device, a request command frame for polling data pending for the sourcedevice; allocating data to be sent in the request command frame; and transmitting the request command frame having the allocation data to be transmitted to the target device.

Description

[0001] This application is a divisional application of the patent application with the same name filed on December 11, 2013 with the application number 201380081504.4. technical field [0002] The invention relates to the field of data transmission between a source device and a destination device, wherein the devices employ a protocol defining request command frames. In particular, the invention relates to a method of transmitting data frames, and a corresponding device configured to transmit data frames. More specifically, the present invention relates to the field of distributed data collection as part of facility management. Background technique [0003] There are many established protocols for data exchange and communication. Some protocols are adapted to the specific characteristics of the communication channel employed, since the protocol specification takes into account, among other things, the data rate of the channel, whether the channel is shared, the channel leng...
