Figure 1 shows the structural 1-3 are received in a certain sequence of the proposed device; on the veracity. When changing the direction of the figure 2, the time diagram of the movement of the monitored object is shown by the device's operation (if two dimensions are possible when changing the direction of movement after the direction of movement does not occur, the signals alternate the signal arrives at the moment of changing the direction on one of the information buses), or the movement on one of the information fig. 3 is the same, if the change in the front busbars 1-3 there is a signaling voltage of the movement accompanied by, or at this moment on all tires Poithor Niemi signal on. one of the information 1-3 signals are missing. In the first case, if, at the time of the reverse tp, the signal device contains informational cash, for example, on the busbar (-3, trigger register 4-6, not 3 (Figure 2b), then after the reverse, 7–10, elements 11–20, a pulse on bus 2, AND-HE 21 and 22, circuit 23 is formed (figure 2b), the second — on bus 1 (figure 2a) , vanilla pulses and strobe, reset, and the third - on bus 3 (Figure 2b), etc. records and fast trigger 24.

The installation of the output trigger 24 according to the result of the comparison operation is performed using the trigger elements AND 20 and AND-NOT 21 and 22 when the strobe pulses arrive at their second inputs (fig.2d, rear). Setting the triggers of the register 4-5 to the zero state is performed by applying reset pulses to the S-inputs (Figs. 2e, Ze). Writing information about the current status of information buses 1-3 to the trigger register 4-6 is done using write pulses (Fig. 2g, G), and the total duration of the pulses produced by circuit 23 is chosen from the condition where T - the duration of the clock pulses corresponding to the maximum speed

At the same time, the output of the trigger circuit IS-NOT 22 produces a constant positive voltage (Fig. 2p), with the result that after the reverse this output does not affect the state of the output trigger 24

After the reverse of the monitored object, let the change in the order of alternation of pulses on information buses 1–3 correspond to the indicated second case (Fig. 3a, 3b, Sv). The order of operation of the device before the reverse is no different from the specified order for the first case. However, after the reverse, i.e. at t tp, with the arrival of the first

At the same time, the output of the trigger circuit IS-NOT 22 produces a constant positive voltage (Fig. 2p), with the result that after the reverse this output does not affect the state of the output trigger 24 After the reverse of the monitored object, let the change in the order of alternation of pulses on information buses 1–3 correspond to the indicated second case (fig.Za, Zb, Sv). The order of operation of the device before the reverse is no different from the specified order for the first case. However, after the reverse, i.e. at t tp, with the arrival of the first the sync pulse, the order of operation changes — at the output of the element OR 8 along impulse. At the output of the AND 20 circuit, a positive pulse also appears (Fig. 3m), which, acting on the C input of the output trigger 24, is The pulse with (FIG. 3L), the action time of which coincides with the action time of the corresponding strobe 25, pulse.

In this case, from the outputs of the circuits AND-NE 21 and 22, during the action of a given pulse, the R and S - inputs of the trigger 24 are supplied with a voltage corresponding to 1 35 (Fig. 3, 3). Starting from the second clock pulse after the reverse, the device works in the same way as the first case. Thus, if, after a change in the direction of motion of the object being monitored, a pulse appears first on the same information bus on which it passed last before by changing the direction of motion, the proposed device allows you to capture the moment of change by changing the direction of motion, the proposed device allows you to capture the moment of change control of the movement of the controlled object immediately on the first pulse. appearing on information tires after changing the direction of motion.
