Abstract

The invention can be used to switch three arbitrarily supplied signals to the input buses 1-3 of the switch in a predetermined order. The switchboard also contains output buses 4-6, counting trigger 7, counters 8-10, blocks 11-13 keys. Each of the blocks contains keys 14-16, the control input of each of which is connected to the output of the corresponding counter. The control input of the counter 8 receives signals from the control strip 17. In this case, the counter 8 switches to the next state, the key 15 closes and the key 14 opens. At the same time, the trigger 7 and the counter 9 close and the key 15 closes, and the key 14 opens. The technical effect of using the three signals switch is the ability to automatically create all the options commutations of three input and output buses, as well as in the increased speed. 1 il. 1СЛ with ГЧЭ ёо :: JV CO

Description

The invention relates to switching devices used in electrical engineering, in particular for switching three arbitrarily supplied signals to input buses in a predetermined order.

The purpose of the invention is to increase the speed due to the automatic reassembly of switching options.

The drawing shows the functional diagram of the switch of the three signals.

The switch of three signals contains three input 1-3 and three output 4-6 buses, counting trigger 7, counters 8-10, blocks

the counter 8 switches to the next state, the key 15 closes and the key 14 of the key block 11 is opened. At the same time, the trigger 7 is triggered, with a positive voltage drop at the output of the latter, and a negative voltage at the inverse output. In this case, the counter is triggered. 9 and closes the key 15, and opens the key 14.

Thus, after the first, with respect to the received initial state, a positive voltage drop, tires 3–6, 2–4, and 1–5 are closed together.

With a second positive voltage drop on bus 17, counters 8 and 10 and input and output buses SoE11 -13 keys operate, each of which contains keys 14–16, the control input of each 15 dn-tc between them in the variant: 1–5, 2-6 of this key is connected to the output of 3-4, respectively, similarly after the third differential

The control input of the counter 8 is connected to the control bus 17 and the counting input of the trigger 7, the output and inverse output of which are connected respectively to the control inputs of the counters 9 and 10, the input bus 1 is connected to the input of the key 14 of the block 11 of the keys, the input of the key 15 block 12 keys and key input 16 block

The technical effect of using the proposed three-signal switch consists in the possibility of automatic 13 keys, the input bus 2 is connected to the input and output buses.

The three-signal switch works barely, blowingly.

For the initial state, any of the six states of the trigger 7 and the counters 8-10 indicated below can be assumed (the setup diagram of the switch to the initial state is not shown).

The initial state of the switch is such that the keys of all 14 key blocks are closed, while the input bus 1 is connected to the output bus 4, the input bus 2 is connected to the output bus 5, and the input bus 3 is connected to the output bus 6.
