SU382121A1 - DEVICE FOR SIGNALING ABOUT AN EMERGENCY OF OBJECTS - Google Patents

Description

one

The alarm condition device is used at various process and industrial installations to alert about the emergency condition when the parameters reach their limit values.

Devices are known for signaling the emergency state of objects, containing sensors of signals, an indicator of the sequence of signals, whose inputs are connected to the outputs of a storage unit, one input of which is connected to a signal pickup unit.

The proposed device differs from the known fact that a differentiating unit, an in-phase pulse distributor and a decoder are entered into it, one of the inputs of the descrambler is connected to the output of the differentiating unit, the input of which is connected to the signal sensor, another input of the decoder is connected to the output of the blue-phase pulse distributor, one whose inputs are connected to the output of the differentiating unit, and the other is connected to the signal pickup unit, and the output of the decoder is connected to another input of the storage unit.

This allows to increase the reliability of the device.

The proposed device for signaling the emergency state of objects is shown in the drawing and contains signal sensors /, differentiating unit 2, in-phase pulse distributor 3, decoder 4, memory, device 5, signal succession indicator 6, signal acquisition unit 7.

The device works as follows. In the initial state of the signaling device, the common-mode pulse distributor

3 prepares the first channel of the decoder

4k to receive the signal of the sensor that worked first. When any sensor signals (and the appearance of the first signal) is triggered, a voltage is applied to one of the inputs of the differentiating unit 2 and from there to the decipheror 4.

From the decoder, the signal on the first channel enters the memory 5, and then on the output-to the indicator 6 of the sequence of signals, where it is recorded by the first indicator, in the first place.

The rear edge of the pulse, separated by differentiating unit 2 from the signal of the first sensor, prepares the second one using the common-mode pulse distributor 3.

decoder channel 4 to receive the next signal of any sensor. From the sensor that triggered the second, the Xishal hits the second indicator, with its falling edge, the signal prepares the third channel of the descrambler to receive the next sensor signal, etc.

To bring the alarm device back to its original state, they act on the pickup device. This removes the memory from all elements of the memory device and returns to the initial position the common-mode pulse distributor.

The alarm device can operate from any number of sensors and indicate the sequence number of their queue.

The speed of the entire alarm device depends on the speed of the elements included in it. Thus, the alarm device on contactless logic elements of the series “Logic T, can clearly distinguish two signals, one after the other after 0.0004 seconds.

The speed can be even greater with the use of special micromodular high-speed elements.

Subject invention

A device for signaling the emergency state of objects, containing sensors of signals, an indicator of the sequence of signals, whose inputs are connected to the outputs of a storage unit, one input of which is connected to a signal pickup unit, characterized in that, in order to increase the reliability

devices, a differentiating unit, an in-phase pulse distributor and a decipher are entered into it, one of the inputs of the decipher is connected to the output of the differentiating unit, the input of which is connected to signal sensors, another input of the decoder is connected to the OUTPUT of the in-phase distributor of pulses unit, and the other - with the block removal of signals, and the output of the descrambler is connected to another input of the storage unit.
