Description

iSt) MONITORING DEVICE

 , OBJECTS,

one

The invention relates to the technical means of operational dispatch control and monitoring of technological objects.

A device is known comprising a power source, a buzzer, an activation button (position switch), and individual alarm cells containing a sensor, a signal lamp, diodes, and a Cl relay.

The drawbacks of the device are the lack of ability to check the health of signal lamps and fuzzy operation in the period when the sensor of another object is triggered when the quit button is pressed.

Closest to the proposed technical entity is a device for monitoring the state of objects, containing signal cells, each of which is made on diodes and signal relays, one output of which is connected to the contact

the sensor and through its own closing contact and the first diode with the contact for the common signal cell of the memory reset key, through the second diode with the contact of the test button, through its own closing contact and the third diode with the first quit relay, the second output of the alarm relay is yuchen to the second own closing contact and through the fourth diode to the contacts of the quit button and the memory key, a buzzer connected to one of the closing contacts of the first quotation relay, a multivibrator connected to the other the first acknowledgment relay and the indication cell on the signal lamps, the second quit relay through the make contact of the first quit relay and the fifth diode are connected to one output of the signal relay, the first signal lamps are connected to the power source via the corresponding second contact of the queuing relay, the second signal The lamp is connected through an additional diode and a closing contact of the corresponding signal relay to the corresponding C2J button.

A disadvantage of the known device is low accuracy in the periods when, after pressing the quit button, the sensor of another object is triggered, after pressing the lamp test button, the sensor of any object is triggered.

The purpose of the invention is to improve the accuracy of the device.

The goal is achieved by the fact that the device for monitoring the state of objects containing signal cells, each of which is made on the quit relay, the first signal relay, the first winding terminal of which is connected to the anode of the first diode and connected to the first power supply bus through the first sensor through the second sensor is connected to the anode of the second diode and the first terminal of the winding of the second signal relay, the second terminal of which is connected to the anode of the third diode and through its own first closing contact is connected to the second bus power source, which through the first closing contact of the first signal relay is connected to the second terminal of the winding of this relay and to the anode of the fourth diode, the cathode of which is connected to the cathode of the third diode, the cathode of the first diode is connected to the cathode of the second diode, two signal lamps, the first terminals of which are connected with the tire of signal lamps, an indicator, the first output of which is directly, and the second through the first parallel contacts of the switching terminal of the signal for each signal cell connected in parallel to the power supply source and quittance button, a first terminal of which is connected with the second power source bus, the first button pro-. The test button is connected to the first output of the quit button and connected to the first output winding of the receipt relay, the second output of which is connected to the cathodes via its own second closing contact and the series-connected first disconnecting contacts. first

The second diodes, the cathodes of the third and fourth diodes are connected to the second power supply bus through the third make contact, the second output of the first signal lamp is connected through the second contact contacts of the first and second signal relays connected in series to the second output of the second signal lamp, which the second closing contact of the second alarm relay and the first test button are connected to a flat light bus, which through the second button connected in series checking in the second break contact of the first relay signalimogo connected to the second terminal of the first signal light, the second point of connection of the switching contacts of the first and second signal relay through fourth normally open relay contact connected to quittance flashing rail, and through the break contact rel

quitations - to the tire of even light.

FIG. 1 is a schematic diagram of the device; in fig. 2 - timing diagrams for the operation of the device.

The device contains plus 1, minus 2 tires, as well as tires 3 blinks, steady burning 4 and warning lights 5 quotation button B, check buttons 7 and 8, buzzer 9 and signal cells 10 ... 10 Each signal cell contains the first alarm relay 11 with the closing contact 12, the opening contact 13 and the switching contact 1, the second signal relay 15 with the closing contact 16, the closing 17 and switching 18, and also the relay 19 with closing contacts 20-22 and the switching contact 23, diodes 2-227 / sensors 28 and 29, signal lamps 3 0 and 31.

In the device, the first output of each winding of the signal relay 11 and 15 is connected to the positive bus 1 via the closing contact of its sensor 28 and 29, and the second terminals of the windings 11 and 15 are connected to the negative bus 2 via the closing contacts 12 and 16 of these relays.

The device works as follows.
