SU731449A1 - Multichannel signalling device - Google Patents

Description

The invention relates to the field of automation of technological processes and can be used for signaling and reporting information on the deviation of the parameters from the norm.

Multichannel devices for signaling the inaccuracy of a monitored object are known, containing audible alarms (garibor, multivibrator with electromagnetic relay - as load, "switch off the sound, test button for warning lamps and. For each channel of signalization the closing contact of the sensor, relay for switching the instrument, alarm lamia and relays. switching the mode of burning the signal lamp and turning off the sound device and the multivibrator 1.

: The disadvantages of the known devices are their low reliability, since they do not both store the signal that caused the alarm elements to work.

The closest to the technical solution of the invention is a device for signaling the unlawfulness of a monitored object, in which there are two relays in each "alarm signaling channel", one of which serves only to switch on the multivibr and sound

signal tribo. At the same time, in each cell there is one 1VY alarm (water of the relay coil is connected to one end of the signal lamp, with the sensor iKOHTajKTOM and through the first diode with its own disconnecting relay contact, and the other terminal of the relay coil is connected with one of its own contact and anode of the second diode, the other The end of the signal lamp is connected to another disconnecting contact of the relay, and the switching cell of the sound element, to which the multi output; of the vibrator through E) is connected to the load relay, a test switch, which through the third diode 15 in each cell Aliza-Ching. Connected: to one .LO1VO.CON of the alarm relay, and the switch-off key, of the audio element, which is connected to the cathode of the second D1 ioda, alarm relay, control relay, two of which are connected to the output of the multivibrator and sound element; for: a load relay contact is connected to another disconnecting circuit of a relay. Each alarm cell 2.

The disadvantages of the prototype device include the absence of elements for storing the incoming signal after it disappears, which makes it impossible to use coiBMecTHo with protection and blocking devices for IB information transfer systems (all 1-III signals on the burner and all the lighting systems. at least one contact of the sensor, which makes it difficult to search for the signal that has been again burned, i.e., the reliability of operation is low. The purpose of the image, the retentivity: - increases the reliability of operation j CTipoftcTiBa. In the multichannel signaling device. In the cell of switching on the sound element, a key is additionally inserted with latching positions and memory reset connected to each cell of the alarm through another closing contact of the relay and an additional fourth diode, the key from the fiber | Key 011K | Lucheni of the sound element, and winding of the relay} 1 is connected with disconnecting contact / relay of the alarm cell relay. The scheme of the multichannel device is shown in the drawing. The device starts to interrupt the cells il n 2 alarms by numbers (for the monitored parameters and the common cell 3 for switching on 3BjiKOB0 .ro elements. The alarm cells have one relay 4 with closing contacts; кm мИИ 5 -and 6h break contacts 7 п 8, м A rotary lamp 9, tlO-13 diodes, sensor 14 contact. The cell of the sound element switches on the multivibrator 16, the load relay 1 with the closing contact, 17, the relay 18 controls with the closing contacts 19 and 20, and the sound the first element 21, the key 22 of the memory reset, the key 23 in, poiBeipiK "alarms, the key 24 off 31c element and key 25 with latching positions. The device works as follows: In case of deviation from the monitored tare meter of the circuit / sensor / 4 contact and to the positive terminal of the power source 26 through (sensor contact 1К1а /, diode 12, the opening contact in, the relay 4 is connected to the relay 18 for switching on the sound element and the multivibrator; the second end of this winding is relay 18 (connected to the negative terminal of the power supply source 26. After activating, relay 18 with BOTH short-circuited pins 19 and 20 zazzkaet (multivibrator 15, the load of which includes a load-carrying relay 16, and sound element 2.1. After zayuoka multivibrator 15 Hainpiy3O4Hoe | relay 16 on (fixes zvkkat and razmat. Contact. ignition signal lamp 9. flashing light. After closing the contact. key 24 disconnecting / wiring 31 ovuzh: ovogo.go element and a multi-vibrator triggers the relay and BOOM for the hinge contacts 5 and 5 becomes on self-vat, disconnecting pin 8 turns off the relay 18 f. of turning on the 31wy1CYu1 of the elec a multi element and a multivibrator, a sound element and a multiwire 15. With it, the switching contact 7; the first gives the warning lamp 9 for burning in a steady light. Thus, the 31V1 element is disconnected, the information about the parameter disconnection from the norm is presented equal to of the common signal lamp of the corresponding channel, relay 4 (In cell 7 there were alarms for (remembered a signal of abnormality and if that (alarm signaling triggers protection, leading to the disconnection of technical equipment), the signal which caused this is not vanishes. Circumferential production (with key 22. All cells 1, 2 alarms work in the same way as described by I, (P. When closing the contact of the corresponding sensor. (Checking the accuracy of cells / and 2 alarms are checked by closing the KOHTaiKTa key., and 23, and the warning lamps of all 1K / 2 alarms, relay 18, multivibrator 15, load relay 16, and conforming element 2 / are checked. With the contact of the key 23 pro closed, check the alarm cells and close the contact (Key 24 deviations from a sound element are further / verified by operation The elements of the signaling device, and the signal l.mpy horns / t even Ovet, turn off the multiviewer 15 and the sound element 21. After the contacts of the keys 23, 24 and 22 are opened, the circuit returns to its original state. The capabilities of the multichannel signaling device into the common cell 3 of the sound element switch-on, a key 25 is inserted with fixed-section positions, which allows the L 2 signaling cells to operate in (signal storage mode as follows). When the contact of the key 25 is closed, all the cells /, 2 alarms latch the positions start working in the standby mode, because when a signal appears in the form of a sensor 14 contact, relay 4 is triggered in the alarm cell and the alarm l.mpu I do not turn on the multivibrator J5 and the sound element 2il, and the response time of the relay is 4 01 Gy. m (at a minimum. the duration of the signal that is memorized. - The circuit records the deviation of the parameter from the pitch, not distracting the operator with an audible signal. If necessary, the operator can verify the presence of the signal that caused the L 2 signal to work). from .. the aza11nu1 contact of the key 23 for resetting pa.m and, (at the same time it is up to the ALARM condition (signal 9) it is possible to determine the presence of the signal 1B current moment, because in this case the amine does not go out. Signalization in aiKOM mode. I praised the work of the teacher, increases the reliability of the slob and is provided and eco information
