The invention relates to telephony, in particular to schemes of combined installations for calling, negotiating and unlocking a lock in residential buildings, and is an improvement of the device according to the author. No. 1131042.

The purpose of the invention is to expand the functionality by controlling the lighting in the stairwell.

FIG. 1 shows a structural electrical circuit of the device; Fig. 2 is a structural electrical circuit of a lighting control unit.

The device for calling, bargaining and unlocking the entrance door of the entrance contains a call unit 1, a control unit 2, an apartment code definition unit 3, apartment blocks 4, a unit

connection, block 7 number selection apartment, the converter 8 position code in binary-decimal code, speaker 9, converter 10 binary-decimal code in decimal code, block 1 1 coding apartment number, blocks 1 2 code identification, switching keys 13, lighting control unit 14, lighting control line 15 and p diodes 16, Each apartment unit 4 contains a loudspeaker 17, first 18 and second 19 pins, resistor 20 and a capacitor 21. Broadcast control unit 14 contains a pulse shaper 22, first 23 and second 24 trigger Generator 25, a clock counter 26, a switch 27, the electronic key 28 and relay 29 incorporating the illumination.

The device works as follows.

To call the tenant of the desired apartment, you must alternately press the buttons from 0 to 9 on block 7 of the choice of the apartment measure of the node of the 1st call. The number of buttons pressed when the apartment is called is determined by the maximum number of bits in the apartment number. If there are no bits in the apartment number, then they are replaced by pool when dialing the apartment number. When you press the first button with the digit corresponding to the hundreds of bits in the apartment number, a signal in the form of a voltage corresponding to logic 1 is fed to the input of the converter 8, the position code in the binary-decimal code 10, for

It is transmitted to the inputs of converters 1 0 of a binary-decimal code into a decimal code located at the nodes 3 of the definition of the apartment code. At the same time, at the output of converters 10 of a binary-decimal code, a signal appears in the form of a logical 1 on one and outputs from

0 to 9, corresponding to the dialed digit of the apartment number, and through the block 1, the flat number is encoded to the input of the code recognition units 12. And the first counting unit

The code recognition 12 is connected to the output of the converter 10 of the binary-decimal code to the decimal code, which corresponds to the digit of the hundreds in the apartment number. The second counting input of the code recognition unit 2 is connected with the discharge of tens, and the third counting input of the code recognition unit 12 is connected with the discharge of units.

The inputs of the code recognition units 12 to the outputs of the converters 10 of the binary-decimal code to the decimal one are performed in the unit 1 1 for coding the apartment number with the help of coding jumpers. After three logical 1, corresponding to a certain apartment number, appear at the input of the code recognition unit 12, the logical signal 1, including a switching key 13, which connects the communication line 6 to the apartment block 4 is normalized at the output. pressing any button of the block 7 for selecting the apartment number on the bus. The control appears a voltage that turns on the tone call generator. After dialing the apartment number to the line 6, the corresponding apartment block 4 is connected via the closed switching key 13, while a dialing tone is heard in the head of the loudspeaker 17. Pressing the Talk button in the apartment block 4 corresponds to the inclusion of an additional resistor in the communication line 6, and a signal is formed in the communication line 6 that disconnects the tone generator and turns on the conversation amplifiers. Thus, when the Talk button (contact 19) in the apartment block 4 is pressed, the dwellings can speak, and the visitor can listen, and when pressed, vice versa. If necessary, turn on

Block 5 unlocks the entrance door of the dwelling and presses the Jamoq button (pin 18). In this case, the communication line 6 is short-circuited, the control unit 2 senses this signal and turns on the power supply circuit of the unit 5 unlocking the entrance door. When opening the entrance door, the device returns to its original state.

The lighting control unit 14 operates as follows.

The voltage from the splitter divider 22 of the pulses is fed through a resistor to the light control line 15 and to the bat of the transistor Lormiator 22 pulses. When the contacts 18 and 19 are open in the apartment block 4, the Lormier transistor 22 of the light control pulses is in the open state, and the voltage on its collector has a low potential that is applied to the C inputs of the first 23 and second 24 triggers. The low potential of the output of the first trigger 23 keeps the generator of 25 clock pulses in an idle state, and the electronic switch 28 is turned on, 1 the power supply of the coil of the lighting-switching relay 29 is open, and the entrance lighting lamps are turned off.

When pressing the Lock button (closing contact 18) in any of the apartment blocks 4, the voltage on the base of the transistor Shaper 22 of the pulses decreases, it closes, and the voltage on its collector acquires a high potential that goes to the C inputs of the first 23 and second 24 the flip-flops and flips them to the state corresponding to logic 1. The voltage from the output of the first flip-flop 23 is fed to an electronic switch 28, which triggers and disconnects the power supply circuit of the winding of the lighting switch-on relay 29, which in turn It energizes the power supply lamps, lights the lamps and burns for a time determined by the parameters of the RC circuit of the clock generator 25, which starts operating, and the position of the switch 27. The first flip-flop 23 remains on until will not come to signal

Zeroes from the output of the counter 26 through the switch 27, and the second trigger 24 is transferred to the state of logical 1 for the time required to reset the counter 26, after which it returns to the initial state.
