The invention relates to a maritime alarm system that regulates the movement of water transport and the prevention of collisions of vessels, in particular, the control of electric fires of navigation signs and buoys.

According to the main author. St. N 207О79 known contactless electric glitter. apparatus for automatic control of shore-fire electric lights, navigation signs and buoys. This unit reproduces the flashing, group-flashing and eclipsed characteristics of fire with durations of light and darkness that are multiples of the period of fire, automatically turns off for daylight and turns on for the dark time of day, and also ensures that the goboard lamp turns on when the active lamp is turned off and off. in the installation of the re-2d of the servo lamp into the operating position. The functional diagram of the apparatus contains a generator that is connected to a group of triggers connected in series,

But the known device is unreliable.

The purpose of the invention is to increase the reliability of the device.

The goal is achieved by introducing a second (triggered) frequency divider, a second de-blocker, a prohibition element, an AND element, a control trigger, a video signal converter onto the receiving unit, a clock generator output connected to the first i inputs of the prohibition element and the I element. , the output of the receiving unit is connected to the second inputs of the prohibition element and the element I, and to the input of the video signal converter, the output of the prohibition element is connected to the control inputs of the second (trigger) frequency divider, the counting input of which Connected with the output element And, the codes of the second (trigger) frequency separator and the output of the video signal converter are connected to the inputs of the decoder, the outputs of which are connected to the inputs of the control trigger, the output of which is connected to the actuator trigger input of the light switch. The drawing shows a functional diagram of the described apparatus. It consists of a clock generator 1, a group of successively connected triggers 2-51, which represent a trigger frequency divider, and a decoder b, a reset unit 7, an executive, trigger 8, power amplifier 9 in the lamp 10, light switch 11, element OR 12, lamppoles of bodies 13, prohibition element 14, element AND 15, converter 16. (end) of video signal 17, coming from (ext., It) receiving unit 18, group of flip-flops 19-22, representing a second trigger frequency divider, decryptor 23 and control trigger 24. The clock generator 1 generates rectangular pulses that, after differentiation, arrive at the input of a chain of successively connected triggers 2-5, as well as prohibition element 14 and element 15. Triggers 2-5 operate in the frequency division mode of the clock generator 1 and issue of their outputs, potential signals in a deif (a ra- tor 6, which forms pulses distributed in time, corresponding to the characteristics of the fire according to the duration of light flashes and pauses. The period of fire is continuously repeated through the feedback action provided by the reset unit 7, which, after each light signal ends, triggers 2-5 to the initial state. The impulses of fire characteristics from the output of the decoder 6 through the executive trigger 8 arrive at the amplifier 9 The power which controls the gadget 10. The light switch 11, which is a trigger circuit with a photoelectric sensor at the input, pulses the actuating trigger 8, providing a non-contact switch ix elektroprbbleskovogo apparatus in the daytime and its inclusion in the nighttime. The element OR 12 turns on the lampspace of bodies 13 only when the masking lamp 10 is blown. The inputs of the prohibition element 14, element 15 and converter 16 can receive video signals 17 from an external receiving device 18, which is shown in dotted lines in the diagram. If there is no external signal, then the pulses of the clock generator 1, the passage through the prohibition element 14, hold triggers 19-22.In the initial state. With the advent of video signal 17, prohibition element 14 does not let through, and element 15 transmits clock pulses to the chain of triggers 19-22, which, working in the frequency division mode of clock generator 1, count the time of action of the external video signal 17. With the end of the signal 17 The signal converter 16 generates an acute pulse to the decoder 23. In the latter, according to the matching scheme, compare: The duration of the external video signal 17 with the specified time settings generated by the trigger 19-22 (provided three time settings). If the video signal 17 matches the first time setting, the decoder 23 outputs a signal to the reset unit 7, which returns the triggers 2-5 to the initial state. This external signal provides the in-phase operation of a group of navigation lights equipped with the proposed electric probes. When the video signal 17 coincides with the second or third time setting of the decoder 23, the control trigger 24 is switched, the output of which is connected to the executive trigger 8. As a result, it opens or closes the path to the signals of the decoder 6 to the power amplifier 9 and the pump control 10. These external signals ensure the operational control of the navigation lights at any time I eat days. invention Contactless electric blasting machine according to ed.
