(54) DEVICE FOR INDICATION

one

The invention relates to monitoring and signaling and can be used in emergency protection systems and other tux areas where indication and storage of the order of arrival of signals in time is necessary.

A device for signaling is known, which contains sensors that indicate a signal that arrives first, by flashing the corresponding pump on the display, and the subsequent signals that come — by steady burning of the corresponding signal lamps.

However, in the known device, it is impossible to establish the root cause and the course of development of the emergency process over time, based only on the order in which the sensors are triggered without taking into account the time delays of the emergency protection device.

The closest to the invention in its technical essence is a display device comprising sensors, the outputs of which are connected to a sensor unit, voltage sources, the negative terminals of which are combined and connected to a power supply circuit, a blocking relay element, one output connected to one of the inputs the display unit, the output of each bit of which is connected to the output of the corresponding sensor through the divider unit; the outputs of the block of sensitive elements are connected to the corresponding 40 inputs of the blocking relay element, the other output of which is connected to the second input of the block of sensitive elements; positive terminal of the first voltage source

t5 is connected via a switch to the voltage input of the storage of the display unit, and the positive terminal of the second voltage source is connected to the voltage input of the memory of the sensitive element unit.

The known device does not allow to determine the sequence in which 9 signals from the sensors appeared in time, which does not allow seeing and evolving the cause of the occurrence and development of an emergency situation. The chain of the invention is to expand the functionality of the device. The supplied circuit is achieved by including in the display device, sensors, blocks; indications, the first inputs of which are combined, a reset signal control unit, a priority code generator, an indicator activation unit, delay blocks, emergency protection blocks, the output of each sensor is connected to the first input of the corresponding delay unit and to the input of the corresponding emergency protection unit, the output of which is connected to the second input of the delay unit, the output of each delay unit is connected to the second input of the corresponding about the display unit and the first inputs of the sequence code, the output of the control reset control signal unit is connected to the third inputs of the delay units, the third inputs of the display units and the second input of the priority code generator, the output of which is connected to the fourth inputs of the display units and to the input of the indicator on unit, the output of which is connected to the first inputs of the display units. The drawing shows a block diagram of the device. The device contains sensors ki of object kontrop, blocks of y, emergency protection, blocks of delays, indication blocks, as well as block 5 of generating a reset signal, a priority code generator 6, block 7 of switching on indicators, corresponding to the number of sensors. The device works as follows. In all blocks 3 -3 delay set the same value of the delay time of the signals from the sensors, -. The time delay value is chosen to be greater than the maximum delay time value of the sensor signals by blocks of 2–2 j emergency protection. When the device is switched off with a control signal from the output of the reset signal control unit 5, the device is reset. In this case, the signal from the output of the signal control unit 5 is fed to one of the inputs of the generator 6 of the priority code and sets 1 4 in it the code O. The same signal is applied to the corresponding inputs of all delay locks and 4f-4y blocks, indication, while unlocking all blocks of delays and installation of the code O in all blocks of indication. The signal of code O from the output of the formaker b of the priority code comes in and the input of the indicator off block 7 generates a signal in it which from the output of block 7 goes to the corresponding inputs of all the blocks, the display cuts off the indicator power, sets the device to its initial state. The job description is given for one channel. In this case, the signal from sensor 1 is fed to one of the inputs of delay unit 3, including the delay of the signal for a set time. In addition, the signal from sensor 1 is fed to the input of the emergency protection unit 2, at the output of which a signal is generated that is fed to another input of the delay unit 3. This signal is simultaneously controlling for the executive bodies of the object under control (not shown in the drawing). After the set delay time has elapsed in the delay unit 3, the presence of a signal at the input connected to the output of the emergency protection unit 2 is checked. If the specified signal is present, a pulse signal is output at the output of the delay unit 3, which is fed to one of the inputs of the sequencer 6 of the priority code and one of the inputs of the display unit 4. At the same time, the repeated formation of the output signal by the delay unit 3 is blocked. On the leading edge of the delay unit 3, the order code generated in the driver 6 is increased by one, and on the falling edge of the same image, only the indication of the order code in the display 4, coming from the driver form 6 of the priority code for one of the inputs of block 4 of indication. At the same time, the sequence code from the output 6 of the imager enters the input of the indicator switching on unit 7, and in the case where the priority code is different from zero, the indicator switching unit produces an output signal to the corresponding input of the display unit 4 and turns on the power to the indicators 7. the indicator 4 of the display unit is indicated by a figure indicating the alarm sequence of the arrival

napa on the described channel, and the number of the display unit 4 corresponds to the number of the sensor G, which caused the emergency protection.
