Definitions
- the invention relates to a data bus for several subscribers that are connected to one another via a star coupler.
- a data bus is known from the unpublished German patent application 19720401.
- the subscribers are connected to the data bus via transmission / reception modules.
- Optical bus systems can cause the aging of the transmitter diodes or frequent bending changes the fiber optic cable or its damage to reduce the light output at the receiving diode and thus lead to disturbances in bus traffic. Such an error cannot be automatically recognized and diagnosed
- the invention has for its object to provide a data bus of the type mentioned, which offers the possibility of recognizing a deterioration in the transmission quality
- An advantageous embodiment of the invention is described in claim 2 This enables the frequency of incorrect data transmission to be determined
- a further advantageous embodiment of the invention is specified in claim 3.
- the addressability of the memory element makes it easy to identify which subscriber is the cause of faulty data transmission. For example, the state of the memory element can be determined via a fast interface (e.g. B SPI) can be read out by a microcontroller assigned to the star coupler
- the memory element can be reset, for example, after an error-free transmission or also after reading out by the microcontroller. A faulty data transmission that occurs again afterwards can be recognized and distinguished from the previous error
- two subscribers T n and T n + 1 are connected to a data bus D via S / E (transmit / receive) modules S / E n and S / E n + 1.
- the modules S / E n and S / E n +1 convert from the participants T n and T n + 1 coming optical telegrams into electrical form and pass these signals D ⁇ n , D ⁇ n + 1 as input signals to a logic decision element (AND gate 1) as a central component of a stem coupler K.
- the number of inputs and outputs of the AND gate 1 corresponds to the number of bus users.
- the output of the AND gate drives all inputs (Do n , Do n + 1 ) of the modules S / E n and S / E n + 1 These convert convert these electrical signals into optical signals and transmit these optical signals to the subscribers T n and T n + 1 via optical transmission links (not shown )
- any deterioration in the optical transmission quality can be detected by the transmitter / receiver module S / E n or S / E n + 1.
- a detected error is caused by a low level at the optical data input of the module a short low pulse at the data output is reported to the star coupler as an additional input signal D ⁇ _n, D ⁇ _n + 1
- This error state is stored in a buffer (7) at each input of the star coupler.
- a counter (8) is assigned to each signal input, which is incremented by one during a transmission frame if an error is reported by the associated S / E module.
- the described counter can Read out and reset by a microcontroller via a serial interface (e.g. SPI) With this function, the optical transmission paths can be diagnosed by all bus users
