Abstract

The solution is from the field of electronics. It concerns the connection of multiple signaling and registration of two-value monitored states. The essence is that the input is connected to both a shaping circuit and a signaling circuit, which is further connected to a power supply and a filter, while the shaping circuit is connected to an evaluation circuit with signaling, which is connected to the power supply via a switching circuit.

Description

The invention relates to the connection of multiple signaling and registration of two-valued monitored states in dispatcher traffic control.

So far, in the short-term duration of the monitored status, the dispatcher is often not able to register the signal and arrange for correction. · To capture these short-term signals, a complex relay circuit is required when using classical relay evaluation ·

These disadvantages are overcome by the wiring of multiple signaling and registration of two-valued monitored states comprising the forming, evaluating and switching circuits according to the invention, characterized in that the forming circuit is connected to the input and the signaling circuit is connected to the power supply. · Two-valued monitored states are evaluated by circuits consisting of semiconductor discrete and integrated elements. This means that the monitored 8-state of any duration is registered and signaled to the dispatcher. until the responder reacts to it and cancels the registration · This signaling lasts only for the duration of the guarded state · If the guarded state has already disappeared before canceling the registration, the signaling is canceled immediately after canceling the registration ·

The advantages of this multiple signaling system are its low production and space requirements, increased service life and thus operational reliability compared to the method used so far, eliminating possible faults when using interchangeable modules.

The attached drawing shows an exemplary embodiment of the connection of multiple signaling and registration of two-valued monitored states, where 1. the signaling circuit is formed by a thyristor switching unit and a signal. 4 of the filter 6 is connected to the power supply 5, block 7 is the actual signaling

- 2? .

• An undesired status signal of any length is applied to the input of the forming circuit 2, where it is shaped to the required pulse for the evaluation logic circuit 3, which processes the pulse and closes the switching circuit 4 with its output signal. which, by connecting the filter 6 to the power supply 5, changes the power supply. voltage at the source from unfiltered to filtered · The undesired status signal is also switched on by the signaling circuit JL and since it is connected to the filtered voltage, it is switched on until the dispatcher registers the signaling and before resetting the evaluation logic circuit 3. After that, the signaling circuit JL only signals if it insists on the input of the signaling circuit

1_ unwanted state signal · Number of forming circuits 2 and signaling circuits JL is equal to β number of monitored process states · Evaluation logic circuit 3 is common for several monitored states - N - input gate evaluates N - 1 different monitored states · The switching circuit of the filter 4, the power supply 5 and the filter 6 are common for any number of monitored states. The circuits of the evaluation logic 3 can be connected in parallel to increase the number of monitored states.

The invention can be advantageously used in all areas of the industry controlled by the dispatching facility.
