(54) SOFTWARE CONTROL DEVICE

The device for software control contains a power source 1, a shaper 2 pulses, an element OR 3, a generator of 4 pulses, an element BANE 5, a decimal t-time counting counter 6, an inverter 7, an element BANE 8, a display unit 9, an n-input element OR 10, sensor 11 of object control parameter 12, AND element 13, AND-NO element 14, BAN 15 element, trigger 16, BAN 17 element, switch 18 of the program set.

The device works as follows.

When the power source I is turned on by shaper 2, a pulse is generated to set the counter n of all the device triggers to the zero state. In the absence of a signal from the sensor AND the control parameter of the object at the output of the element BAN 8, there is a logical zero ("O), hence the output of the element I 13 -" O. This signal is fed to one of the inputs of the OR 10 element, the number of inputs of which is determined by the number of channels, control objects 12. From the output of an element 10 or 10, the signal "O prohibits the passage of pulses from the generator 4 through the element BAN 5 to the counting input of counter b, is inverted and fed to the information input of the BAN 17, the control signal of which is the zero output of counter 6 -" 1. As a result, “1” appears at the output of the BAND 17, therefore, the indication block 9 informs about the zero state of the counter.

When a signal is received from the sensor 11 of the control parameter of the object, the output of the BAN 8 item is set to "1, because its control input is" 1. At the output of the element AND NOT 14 there is " 1, therefore, " b. This signal, having passed through the element OR 10, opens the BANE element 5, i.e. the counting input of the counter 6 is open, the output of the inverter 7 is set to "O" and the O input appears at the control input of the BANE element 17 9 informs about the operation of the counter. ,

The required time delay is set on the program set switch 18. When appearing at all inputs of the element AND-NOT 14, “I at its output is set to“ O. The difference from "1 to, prokd through the element LOCK 15, switches the trigger 16 to the second steady state and includes the object 12. The appearance of" O at the input of the element And 13 changes its output state to "O, and this leads to the closure of the element. 5 and, consequently, the counter 6. The difference from "1 to" O, having passed through the element OR 3, sets the counter to the zero state, the display unit 9 informs about the zero state of the counter.

When a signal is received from the sensor 11 of the control parameter on the second channel, the principle of operation of the device is the same as that discussed above on the first channel. But in the case of the occurrence of the signal "1 on all inputs of the element AND-NO 14 of the first channel at the output of this

element is set to "O, because after working on the first channel at the control input of the element BAN 8," O, therefore, "O at the output of the element And 13 of the first channel does not change.

When the signal is turned off by the sensor of the control parameter on the first channel, the difference from "G to" O arrives at the zero input of the trigger 16 and transfers it to the zero state; object 12 is turned off.

The sensor of the control parameter of the first channel does not output a signal, but the second channel is operating. In the case of the occurrence of the signal "1" on all inputs of the element AND-HE 14 of the first channel at the output of this element a difference is formed with "1. on "O. This differential does not pass through the element BAN 15. As its control input has "O", therefore, the trigger 16 does not switch. "O at the output of the element And 13 does not change, since at the information input of the element is BAN 8 - O.

;

Independent time management of p channels from control parameter sensors, automatic shutdown and reset of the counter to the zero state after each channel operation, indication of the counter status increases the reliability of the device operation, and significantly increases the range of time exposures.
