Description

The invention relates to radio electronics and can be used in control equipment of communication systems, in automation and computer technology for training operators, control systems,

The purpose of the invention is the expansion of functional capabilities by providing a mode for learning operators.

FIG. Figure 1 shows the electrical circuit diagram of a device for controlling the sequence of alternating analog signals; in fig. 2 - timing diagrams for the operation of the device.

A device for controlling the sequence of alternating analog signals contains N. blocks 1-1 ... processing analog signals, including) fourth elements AND-NOT, ... , fifth elements 3-1 ... .. 3-N, the first elements AND-NOT 4-1,., ... 4-N, the second elements AND-NOT 5-1 ... ... 5-H and the third elements H-HE6-1 ... , ..6-Н, information display unit 7, generator 8 and pulses and inverter 9.

The device works as follows. ,

By applying to the input P (Fig. 2 (x) high level of the signal, the self-learning mode is activated, by applying a low level signal to the input of the P circuit, it switches to the control mode.

In the initial state, in the first mode, the C-1 -1 signal is received at the first input of the .f-ro block 1-f of processing analog signals, and the signal Ci is shown at the second input (Fig.). Thus, a low-frequency pulse signal from the output of the generator 8 (FIG. 25) passes through quartier | (fig. 2e) and nepBfjM (fig. 2i) AND – NE 2– elements (, 4-1) and is fed to one of the inputs of the third element AND-H 6-1, to another input of which the signal is inverted from the output of inverter 9 (Fig. 2c.), passed through the FIRST element AND-HE 3 t (Fig. 2H and the second element IS-NOT 5-i (Fig.) In this case, the output of the third element IS-HE 6- / forms a high signal level (Fig. 2n),, j, Ha, information display unit 1, the 7th display element is canceled. 1 device bottom Whose level of the signal at the output of the first element AND-NOT 4-t appears high

the potential allowing the passage of a low-frequency pulsed signal from the output of the second element AND-NOT 5-t, through the third element AND-NOT 6-, i to the input of the block. 7 display information, the corresponding display element of which starts operating in intermittent mode.

When a signal is applied after this low level to Cj, the input of the device at the output of the second element IS-NE 5-g also forms a high signal level, and at the output of the third element IS-NOT 6-i a logic zero signal, under the action of which the corresponding indication element is activated block 7 display information.

Thus, in the first mode, when the pre-signal is applied to the information display unit, the corresponding display element is switched on and the display element, which corresponds to the next signal in the interrupted mode, allows the operator to determine the signal switching sequence,

In the second mode, in the initial state, the C i-1 and C inputs of the device receive high-level signals, and the input - a low-level signal.

As a result, the output of the first element AND-NOT 4-1 of the 1-L block for processing the analog signal through the fourth element IS-NOT 2-j. a low-frequency pulse signal comes from the generator output, and the output of the second element is NOT-5-1 under the action of the zero signal from the P input and the high level signal from the C input, a logical zero signal is generated that blocks the third AND-NE element 6-L. The corresponding indication element in the information display unit 7 is thus turned off.

When a low level signal is applied to the input CL -1 of the device, the output of the first AND-NO 4- element (. A signal of a logical unit is formed, and the third element of the AND-HE 6-i remains blocked by the signal from the output of the second element AND-NOT 5-L and - The display indicator block 7 is turned off.

When a low level signal is applied to C after this (the input of the device at the output of the second AND-NOT element is a signal of a logical unit, which enters the input of the third AND-NOT 6-i 5 element, switching

in O and includes the.-and the display element on the information display unit 7.

If, when a low-level signal is applied to the GI input of a device, a low-level signal on the C 1-1 input of the device is absent, then the logical unit signal from the output of the second element IS-NOT 5-.1 permits the passage of a low-frequency pulse signal from the output of the first element AND-NOT 4 -t Through the third AND-NOT element, on the information display unit 7, whose IH element begins to operate in intermittent mode.

Thus, in the second mode, if any analog signals C1 ... CN fall out of a predetermined sequence of their arrival, the disturbances in the sequence of alternation of signals are determined by the flashing indicator of the display unit.

In addition, the first mode of operation of the device can be used to test the performance of the control equipment itself, mainly constantly working in the second mode.

The device returns to the initial state by applying to all the inputs of blocks 1-1 ... 1 No. of processing the analog signals of high levels of signals C1 ... С№.
