Устройство для технологической сигнализации содержит элемент ИЛИ-НЕ 1, элементы И-НЕ 2 и 3, Элементы ИЛИНЕ 4 и 5, элемент ИЛИ 6, сигнальную лампу 7 и размыкающий контакт 8 дат- ⁴⁰чика. Центральный блок содержит звуковой сигнализатор 9, генератор 10 импульсных сигналов, кнопку 11 опробования и кнопку 12 съема сигнала.The device for technological signaling contains an OR-NOT 1 element, AND-NOT 2 and 3 elements, ORINE 4 and 5 elements, an OR 6 element, a signal lamp 7 and an NC contact 8 of the sensor- ⁴⁰ . The central unit contains a sound detector 9, a pulse generator 10, a test button 11 and a signal pickup button 12.

Устройство действует следующим об- ⁴⁴разом.The apparatus ⁴⁴ operates as follows ob- time.

В исходном состоянии контакт 8 и кнопка 11 замкнуты, на выходе элемента 1 имеется единичный сигнал, вследствие этого на выходе элемента 50 6, связанного с элементом 4, устанавливается нулевой сигнал. Выходной сигнал элемента 3 равен 1, поэтому выходной сигнал элемента 5 равен О, в результате сигнальная лампа 7 не .55 горит и звуковое устройство 9 не звучит. При размыкании контакта 8 датчика или(кнопки 11 опробования) выходной сигнал элемента 3 становится нулевым, благодаря чему через элемент 5 проходит сигнал генератора 10 импульсов. В результате действует $ звуковой сигнализатор 9. Сигнал генератора 10 импульсов проходит также через элемент 6, в результате сигнальная лампа 7 мигает.In the initial state, contact 8 and button 11 are closed, at the output of element 1 there is a single signal, as a result of this, at the output of element 50 6 associated with element 4, a zero signal is set. The output signal of element 3 is 1, so the output signal of element 5 is O, as a result, the signal lamp 7 is not .55 lit and the sound device 9 does not sound. When the contact 8 of the sensor or (test button 11) opens, the output signal of the element 3 becomes zero, due to which the signal of the pulse generator 10 passes through the element 5. As a result, an audible signaling device 9 acts. The signal of the pulse generator 10 also passes through element 6; as a result, the signal lamp 7 flashes.

При возврате контакта 8 датчика в замкнутое состояние элементы 2 и 3 остаются в прежнем состоянии, и поэтому сигналы, поступающие на сигнальную лампу 7 и звуковой сигнализатор 9, не меняются, они продолжают сигна»5 лизировать, обеспечивая,тем самым, запоминание срабатываемого канала. £сли теперь оператор нажимает кнопку 12 съема сигналов, на входе элемента 5 устанавливается сигнал 1, а на вы_м ходе - О. В результате световая и звуковая сигнализации прекращаются. Если же при срабатывании, т.е. разомкнутом контакте 8 датчика, оператор нажимает кнопку 12, на выходе элемента 2 устанавливается сигнал 0“, в результате нулевые сигналы устанавливаются на обоих входах элемента 4, на его выходе - единичный сигнал. Сигнальная лампа 7 переходит в режим ровного свечения. На входе элемента 5, связанном с элементом*3> устанавливается сигнал 1 , а на его выходе сигнал 0. В результате звуковое устройство 9 перестает действовать. При возврате датчика на входе элемента 4 возникает сигнал 1, на выходе - Q и лампа гаснет.When the contact 8 of the sensor returns to the closed state, the elements 2 and 3 remain in the previous state, and therefore the signals coming to the signal lamp 7 and the audible signaling device 9 do not change, they continue to signal »5 to lyse, thereby providing a memorization of the triggered channel. £ If now the operator presses the button 12 pickoff signals at the input member 5 is set signal 1, and the course you _m - O. As a result, light and sound signaling terminated. If, when triggered, i.e. open contact 8 of the sensor, the operator presses the button 12, the signal 0 “is set at the output of element 2, as a result, zero signals are set at both inputs of element 4, and a single signal is output. The signal lamp 7 goes into a steady light mode. At the input of element 5, associated with element * 3>, signal 1 is set, and at its output, signal 0. As a result, the audio device 9 ceases to act. When the sensor returns at the input of element 4, signal 1 appears, at the output - Q and the lamp goes out.

Таким образом, в предлагаемом устройстве сработавший канал запоминается, так как лампа продолжает.мигать после возврата датчика до приема сигнала оператором. В результате оператор имеет возможность знать, в* каком месте возникло нарушение, а не только то, что оно где-то было. Это позволяет своевременно предпринять профилактические мероприятия и предупре- . дить наступление повреждения.Thus, in the proposed device, the triggered channel is remembered, since the lamp continues to blink after the sensor returns before the operator receives the signal. As a result, the operator has the opportunity to know * where the violation occurred, and not just that it was somewhere. This allows timely preventive and preventive measures to be taken. Continue damage.

Claims

The invention relates to automation technology, in particular to multi-channel signaling devices with individual light and general sound alerts, and can be used to monitor equipment parameters, such as marine diesel units. The known device of multichannel signaling on logic elements, designed to monitor technological parameters, has the following functionality: the appearance of a blinking light when a sensor is triggered; testing lamp health; manual activation of the horn warning sound signal closest to that proposed by the technical entity is a device for signaling the deviation of the technological parameter, containing an inverter connected via an amplifier to the signal lamp, a rectifier connected to the inverter and the output of the third circuit OR NONE, a sensor and a test button connected to the inputs of the first OR-NOT circuit, the output of which is connected to one of the inverter inputs, one of the inputs of the second OR-NOT circuit, and the first input of the third OR-NOT circuit, the second input of which oh is connected to the pulse generator, and the signal pickup button is connected to one of the inputs of the fourth OR circuit, whose output is connected to another input of the second OR-NOT circuit, and the other input of the fourth OR circuit is NOT connected to the output of the second OR circuit and NOT the third input of the third OR-NOT 2 circuit. The disadvantage of this device is the loss of information about short-term violations, i.e. if the sensor returns to its original state after triggering before the operator presses the Power button, the lamp goes out, and the operator cannot determine which channel signaled the damage. 38 The purpose of the invention is to increase the reliability and expand the functional capabilities of the device. This goal is achieved by the fact that a technological signaling device containing a pulse generator, a warning lamp, a buzzer, a signal pickup button, NRNI elements, a sensor output and a check button, the output of the first element OR are connected to the corresponding inputs of the first one. NOT connected to the first input of the second element OR NOT, entered the element OR and the elements AND-NOT, the first input of the first element AND-NOT connected to the output of the first element OR-NOT, the output of the first element AND-NOT connected to the second input of the second about the OR-NOT element and the first input of the second AND-NOT element, the second input of which is connected to the output of the signal pickup button, the output of the second AND-NOT element is connected to the second input of the first AND-NOT element and the first input rubs its OR-NOT element, the second input of which is connected to the output of the pulse generator; the output of the third element ORINE is connected to the first input of the OR element, the second input of which is connected to the output of the second element OR NOT, the output of the OR signal signal is connected to the output of the third element OR-IE In the drawing is shown coupled audio circuit logic elements on each channel. The device for technological signaling contains the element OR-NOT 1, the elements AND-NOT 2 and 3, the elements ILINE 4 and 5, the element OR 6, the signal lamp 7 and the disconnecting contact 8 of the sensor. The central unit contains a buzzer 9, a generator of 10 pulse signals, a test button 11 and a signal pickup button 12. The device operates as follows. In the initial state, the contact 8 and the button 11 are closed, at the output of the element 1 there is a single signal, as a result, at the output of the element 6 connected with the element, a zero signal is set. The output signal of element 3 is equal to 1, therefore the output signal of element 5 is equal to O ,, as a result, the signal lamp 7 does not light up and the sound device 9 does not sound. When contact 8 of the sensor or (test button 11) is opened, the output signal of element 3 becomes zero, whereby element 5 of the pulse generator 10 passes. As a result, a buzzer 9 acts. The signal of the pulse generator 10 also passes through element 6, as a result the signal lamp 7 flashes. When the contact 8 of the sensor returns to the closed state, elements 2 and 3 remain in the same condition, and therefore the signals to the warning lamp 7 and the acoustic warning lamp 9 do not change, they continue to signal, thus ensuring that the activated channel is memorized. | If the operator now presses the button 12 removal of signals at the input element. 5, the signal t is set and the output is O. As a result, the light and sound alarms are stopped. If it is triggered, i.e. open sensor contact 8, the operator has button 12, signal O is set at the output of element 2, as a result, zero signals are set at both inputs of element k, and a single signal at its output. The signal lamp 7 enters a steady glow mode. At the input of element 5, connected with element 3, a signal 1 is set, and at its output a signal O. As a result, the sound device 9 becomes inactive. When the sensor returns to the input of element 4, a signal 1 appears, at the output - O and the lamp goes out. Thus, in the proposed device, the activated channel is memorized, as the lamp continues to flash after the sensor returns until the operator receives the signal. As a result, the operator has the opportunity to know where the violation occurred, and not only that it is somewhere. This allows timely preventive measures and warnings. to advance on & Apparatus for technological signaling, comprising a pulse generator, a signal lamp, a buzzer, a pickup button, OR-NOT elements, to the corresponding inputs of the first of which the sensor output and the check button output are connected, the output of the first element ORINE is connected to the first input of the second element OR-NOT, in order to increase reliability and enhance functionality, the OR element and the AND-NOT elements are entered into it, the first input of the first AND-NOT element is connected the output of the nepBofo of the element OR NOT, the output of the first element NAND is connected to the second input of the second element; OR NONE and the first input of the second element NAND, the second input of which is connected to the output of the signal pickup button, the output of the second element NANDINE is connected to the second input of the first NAND element and the first input of the third ILIO element B
