Description

1 The invention relates to an AB-1 tomato-and-machine technique, namely, multi-channel signaling devices with an individual light and general sound notification. A device is known. An emergency warning system that contains a sensor, elements OR-LE, a test button, an acknowledgment button, a pulse generator, a fl warning light. The disadvantage of this device is the loss of information of intermittent disconnection of the 5 X sensor contact. The closest in technical terms to the invention is an emergency warning device, containing in each sensor a sensor and a test button, the outputs of which are connected to the component in the "inputs of the first OR-NOT element, the output of which is connected to the first input of the second element OR-NOT and to the first input of the third element OR NOT, the output of which is connected to the second input of the second element. and with the first input of the fourth element OR NOT; the second input of which is connected to the output of the signal pickup button, the output of the fourth element OR is NOT connected to the second input of the third element OR NOT; the output of the pulse generator is connected to. third of it is the input of the second element OR NOT, the output of the amplifier is connected to the signal lamp, the first input of the first element is AND-NOT connected to the output of the first element OR NOT, the output of the first element OR is NOT connected to the first input of the second element AND-NOT, the second input of which is connected to the output of the reset button, the output of the second element AND-NOT is connected to the second input of the first element AND-NOT and to the first input of the additional element OR NOT, the output of which is connected to the amplifier input, the second input of the additional ale cient NOR is connected to the output of the second OR-NO element and to one of the inputs of OR gate common to all channels, the output of which is connected to the audible alarm f 2. The disadvantage of the device is that it does not signal the return of the sensor to its initial state. The purpose of the invention is the expansion of the area of application of the device. The goal is achieved by the fact that an alarm device containing a sensor and a test button in each channel, the outputs of which are connected to the corresponding inputs of the first element OR NOT, the output of which is connected to the first input of the first element NAND, to the nepBCftiy input the second element OR NOT and to the first input of the third element OR-NOT, the Vyosode of which is connected to the second input of the second element OR-NOT and to the first input of the fourth element OR-NOT, the output of which is connected to the second input of the third element That OR NOT, acknowledgment button, the output of which is connected to the second input of the fourth element OR NOT, the reset button, the output of which is connected to the first input of the second NAND element, the output of which is connected to the first input of the fifth OR element NOT and to the second the input of the first element IS-NOT, the output of which is connected to the Second input of the second element, the output of the second element OR NOT is connected to the corresponding input of the element OR common to all channels, the output of which is connected to the audible alarm, a pulse generator and a signal lamp, each The first channel is entered by a squared element OR-NOT, the output of the third element OR-NOT is connected to the first input of the squaring element OR-NOT, the output of which is connected to the second input of the fifth element OR-NOT, the output of which is connected to the signal lamp, and the code of the pulse generator is connected to the second input of the generic element OR NOT. The drawing shows the electrical circuit of the proposed device. The device contains sensors 1, elements 2-7 OR-NOT, elements 8 and 9 AND-NOT, element 10 OR, common to all channels, test buttons 11, acknowledgment buttons 12, reset buttons 13, warning lights 14, buzzer 15, 16 pulse generator. Items 3 and 4 OR-NOT make up the first memory node, items 8 and 9 AND-NOT are the second memory node. The device for each of the channels works as follows. In the initial state, the contact of sensor 1 is closed, and the memory nodes are set so that at the output of element 9 AND-NO there is a single signal (high potential), and at the output of element 6 OR NO (low) potential, the signal lamp 14 is dimmed , at the output of element 4 OR is NOT the first memory node, the zero potential. At the output of element 2 OR-NOT there is a single signal, resulting in the output of element 5 31 (OR-NOT sets zero potential: dial, and does not turn on the sound signaling plug 15. When contact 1 is opened, the output of element 2 OR NOT is set the lower potential, and at the output of element 5 YLI-NOT is a single signal, the acoustic signal 15 is turned on, the second memory node is not switched off, and a zero potential is output at the output of element 9 AND-NOT. The pulse signal from the pulse generator 16 passes through elements and 6 OR-41E on signal lamp 14, it blinks. If the contact of sensor 1 remains in the open state, the operator pushes the first memory node into a disconnect state, at which the signal at the output of the OR-NOT element becomes single, and the signal lamp 14 goes to in the mode of blood luminosity. In addition, a single signal from the output of element 4 W-N-arrives at the input of element 5 OR the NO signal horn 15 stops oTK7no4aTbcjc. In this state, the device remains until the contact of sensor 1 is open, when the contact returns to a closed state after; repairing the damage, the first node of the transmitter is returned to its initial state {signal at the output of element 4 OR -NO disappears, element 7 OR-NOT passes the pulse signal from the generator 16. and the warning light 14 flashes again. The buzzer does not work here. The economic effect of using the invention is due to its technical features.
