Description

 The device relates to telecommunication technology and can be used in monitoring and control systems of automated objects connected to the telephone network.

 To connect the object to the telephone network, a device capable of transmitting and receiving discrete information is required. Due to the fact that subscriber telephone sets of various types are connected to the telephone network, the device in question must be universal, which necessitates its implementation in the form of a set-top box connected in parallel with the telephone set (TA). This will allow subscribers to offer additional paid services for automated monitoring of sensors located at the facility, and remote control of actuators with which the same facilities are equipped.

 The existing equipment for monitoring and backup control of automated radio broadcasting nodes implements the transmission of telemechanical codes on a conversational loop formed between SLTs and does not use the possibility of generating and transmitting discrete information embedded in the telephone network itself.

 These features include the following.

 1. The transmission of discrete information by telephone codes formed by rupturing a voice cable between two SLTs using their disk or keypad dialer.

 2. The transfer of discrete information by the inductor of the automatic telephone exchange (PBX) to the formation of a voice loop by sending a certain number of call signals and call confirmation, with the call signals being sent to the called object and call confirmation to the calling object.

 The formation of the two types of the above discrete information using any type of SLT in manual mode does not require additional devices.

 The use of TA at automated facilities for these purposes is difficult. A TA with a disk dialer is generally not suitable, and a TA with a push-button dialer requires equipping it with additional devices. The reception of the information in question from the telephone network and its indication also require the availability of appropriate additional devices.

 The closest in technical essence to the claimed device is a device selected as a prototype, located on an automated object of a control and monitoring system for transmitting commands over telephone lines.

 The device includes a telephone with a keypad and memory 2, a control unit 4, a decoder 6, a telephone unit for pairing and simulating telephone buttons 8, a control object 9, a call receiving unit 10, a handset lifting simulator 11, a telephone code signal receiving unit 13.

 Block 8 for pairing and simulating buttons TA contains a block 19 for receiving signals from control and control commands, a block 20 for receiving signals from a control unit, and block 21 for receiving signals from a control object.

 The device allows pre-recording in the TA memory of the telephone code of the subscriber number of the control room and the telephone codes encoding the object number and the number of the triggered sensor at the control object.

 When one of the sensors is triggered, a button is pressed to select the subscriber number of the control room from the TA memory and a button to select a situation code. The transfer of a subscriber number to the PBX forms a line (conversation line) between the control room and the control object, with the help of which the device transmits a reporting code to the control room, thereby the device in the system implements the automatic transmission of emergency situations.

 On the other hand, the device receives command codes from telephone lines represented by similar signals, decrypts them, and transmits signals to the object. After the object executes the received command, the device generates and transmits a report on the execution of the command. This is the mode of receiving commands.

 When receiving commands, the device operates as follows: from the communication line, TA2 receives a call signal, which is fixed by the call receiving unit 10, the latter transmits a signal to the handset lifting simulator 11, which simulates picking up the handset on TA2. Between the control room and TA2, a conversation loop was formed, flowed around by a direct current U = 4 V. In this circuit, a telephone code receiver 13 is turned on, which sends a signal to decoder 6 at each line break, and to the control unit 4 when it is closed. The command coming from the communication line is encoded with a code 1-9. Therefore, the public key K17 in the counter CT17 will record the code 0001. After determining the first inter-series pause, the control unit 4 will close the key K17 and send a signal to enable decryption of the DS17, at the first output of which a control signal is generated that will open the key K18. The next digit of the code of nine pulses is recorded by the counter CT18 (1001), which after the second inter-series pause will be decrypted by DS18, on the ninth output of which a single signal will appear, which will be amplified and fed to relay P 1-9 of the unit 8 for pairing and simulating the TA buttons. The relay contact R 1-9 will give a control signal to the control object, the control unit 4 will turn off the power from the receiver 13 telephone codes.

 The control object 9, having executed the command, closes the contact of the relay report relay for a period of up to 1 s. In block 21 of receiving signals from the control object, relays PH and PC are activated, the contacts of which simulate the pressing of buttons B1. This will lead to the reading of the code 8-9 from the memory cell, which TA2 will transfer to the control center by breaking the existing voice loop.

In the mode of transmitting emergency reports, the device operates as follows:
The “dry contact” of the emergency relay RA _{1 has} closed at the control object. In block 8, the pairing and simulation of the TA buttons are triggered by relay RP ₁ , PH ₁ , RP ₁ . Relay contacts rn1 and rp1 formed a signal supply circuit for buttons B1, and the RAS relay simulates the pressing of buttons A16 and includes a call receiving unit, which, through control unit 4, includes a tube lifting simulation unit 11. The subscriber number of the control room is read from cell A16 and TA2 is transmitted to the telephone network. After the conversation line is formed, the emergency code (8-9) will be read out from the corresponding memory cell by the signals from the B1 buttons, which will be transmitted to the control center using breaks in the conversation loop.

 The known device has the following disadvantages.

 1. The equipment is sold only on the basis of telephones with a keypad and memory. TA with disk dialers is not suitable for creating a device.

 2. It forms the final equipment for equipping only control objects; the device does not perform the functions of a control room.

 The present invention is aimed at solving the problem of creating a universal device for monitoring and controlling automated objects suitable for working with telephone sets of any type and made separately from them.

 This goal is achieved by the fact that in the device for monitoring and controlling automated objects, containing a control unit, a continuous monitoring circuit, a keyboard equivalent unit, a call receiving unit, a telephone code receiver and a decoder, the input of the continuous monitoring circuit is information of the input device, the first output of the circuit continuous monitoring is connected to the first input of the keyboard equivalent unit, the second input of which is connected to the first output of the control unit, the first and second inputs of which are connected with the first outputs of the call receiving unit and the telephone code receiver, the first input of which is connected to the second output of the control unit, the third output of which is connected to the first input of the decoder, the second input of which is connected to the second output of the telephone code receiver, a switch, a transmitter, a programmable chopper are introduced, a call acknowledgment unit, an indication unit, and a decoder and a keyboard equivalent unit are tunable, while the corresponding inputs / outputs of the switch are inputs / outputs The device’s odes for the subscriber line and telephone, respectively, the first, second, third and fourth outputs of the switch are connected respectively to the third input of the decoder, to the second input of the telephone code receiver, to the input of the call acknowledgment block and to the input of the call reception block, the second output of which is connected to the first input of the programmable chopper, the second and third inputs of which are connected respectively to the second output of the continuous monitoring circuit and to the fourth output of the control unit, the third, fourth the fifth, fifth and sixth inputs of which are connected respectively to the output of the programmable chopper, to the output of the call acknowledgment block, to the first output of the decoder and to the first output of the keyboard equivalent block, the second output of which is connected to the first input of the transmitter, the second input of which is connected to the fifth output of the block control, the sixth output of which is connected to the first input of the switch, the second input of which is connected to the output of the transmitter. The second output of the decoder is the control output of the device, and the third output of the decoder is connected to the input of the display unit.

 Distinctive features from the prototype are the introduction of a switch, a transmitter, a programmable interrupt and a block for acknowledging a call and the execution of a block of keyboard and decoder equivalents that are tunable, which, together with new connections between the blocks, makes it possible to claim that the invention meets the “Novelty” criterion.

 The use of distinctive features in the known monitoring and control devices of automated objects, allowing to achieve the goal, the authors do not know, which suggests that the proposed invention meets the criterion of "Significant differences".

In FIG. 2 shows functional diagrams of continuous monitoring and a programmable chopper; FIG. 3 is a functional diagram of a transmitter and a tunable keyboard equivalent in conjunction with a call receiving unit, a call confirmation receiving unit, a telephone code receiver and switching unit elements.

 In FIG. 4 shows a diagram of a tunable decoder in conjunction with a display unit and actuators.

 In FIG. 5 shows a diagram of a device connecting to a telephone network.

 The device for monitoring and controlling automated objects over telephone networks contains (Fig. 1) a switch 1, a transmitter 2, a tunable keyboard equivalent unit 3, an indication unit 4, a tunable decoder 5, a telephone code receiver 6, a call confirmation receiving unit 7, a call receiving unit 8 , control unit 9, programmable chopper 10 and continuous monitoring circuit 11.

 The first output of the continuous monitoring circuit 11 is connected to the first input of the keyboard equivalent unit 3, the second input of which is connected to the first output of the control unit 9. The second and third outputs of the control unit 9 are connected to the first inputs of the telephone code receiver 6 and tunable decoder 5. The first and second inputs of the control unit 9 are connected to the first outputs of the call reception unit 8 and telephone code receiver 6, the second output of which is connected to the second input tunable decoder 5.

 The first, second, third and fourth outputs of the switch 1 are connected respectively with the third input of the tunable decoder 5, with the second input of the receiver 6 telephone codes, with the input of the call acknowledgment block 7 and with the input of the call reception block 8, the second output of which is connected to the first input of the programmable breaker 10.

 The second and third inputs of the programmable chopper 10 are connected respectively to the second output of the continuous monitoring circuit 11 and to the fourth output of the control unit 9. The third, fourth, fifth and sixth inputs of the control unit 9 are connected respectively to the output of the programmable chopper 10, to the output of the call acknowledgment unit 7, to the first output of the decoder and to the first output of the keyboard equivalent unit 3, the second output of which is connected to the first input of the transmitter 2. The second output of the transmitter 2 is connected to the fifth output of the control unit 9, the sixth output of which is connected to the first input of the switch 1. The second input of the switch 1 is connected to the output of the transmitter 2.

 The corresponding inputs / outputs of the switch 1, which are the inputs / outputs of the device, are connected respectively to the telephone set 12 and to the automatic telephone exchange 13.

 The input of the continuous monitoring circuit 11, which is the information input of the device, is connected to the output of the sensor unit 14.

 The second output of the tunable decoder 5, which is the control output of the device, is connected to the input 15 of the Executive elements.

The third output of the tunable decoder 5 is connected to the input of the display unit 4. The continuous monitoring circuit 11 (Fig. 2) for five sensors contains five electronic keys K ₁ - K ₅ , five RS triggers T ₁ - T _5, and an OR circuit. The key inputs are connected to sensors, when triggered, the corresponding trigger is set to a single state, the key closes and disconnects the sensor from further continuous monitoring. Through the circuit OR, an alarm signal is supplied to the control unit 9.

A single signal from the outputs T ₁ - T ₅ opens the corresponding key of the programmable chopper 10. Keys K ₁₁ - K _{15 are} connected to the outputs of the register RG. The keys program and memorize the situation, which allows, when fixed by the call signal receiving unit, to start shifting information to RG through input C. The sequential appearance of a single signal at the outputs of the register continues until the signal from the output through the public key and the OR circuit arrives at the control unit 9, which, through the switch 1, breaks the circuit for receiving call signals, the ATC 13 inductor stops their supply. This allows the person who has dialed the subscriber number of the object TA to determine the number of the triggered sensor by the number of audit confirmation signals, and when redialing the number, bring the register to the final (eighth) position and disconnect the call receiving unit from the line and connect the receiver 6 telephone codes through the control unit 9.

If none of the sensors works, then the signal supply circuit to input C will be broken (key K), and the programmable chopper will not accept incoming call signals. This condition ensures the normal functioning of the telephone network in the regular call mode. Block 3 of the tunable keyboard equivalent (Fig. 3) includes a rectangular pulse generator, keys K ₁ , K ₂ , K ₂₁ - K ₂₅ , register RG ₁ with a removable insert encoding the subscriber's telephone number, register RG ₂ with a removable insert encoding a protective number and number of triggered sensor, CT counter of the number of dialing subscriber numbers.

When the sensor is triggered (say N 5), a high level signal is supplied to the VK ₂₅ input from the continuous monitoring circuit 11, the key K ₂₅ will open and prepare a signal supply circuit for the fifth input of the electronic dialer of the transmitter 3.

The control unit 9 will turn on the generator G and open the key K ₁ . The formation of a single signal begins sequentially at the outputs of RG ₁ . These signals through the coding insert will be supplied to the corresponding inputs of the electronic dialer of the transmitter 2.

A report code is generated in the same way when applying pulses through K ₂ to input C of RC ₂ register. The reporting code contains a protective part (in our case 31) and an information part (5).

 The tunable keyboard equivalent unit 3 works in conjunction with the transmitter 2, which is represented by the standard circuit of a telephone set or set-top box with a keypad [3]. The transmitter includes a diode bridge, an IR pulse switch, an electronic dialer, an RK spoken key, and resistance R (equivalent of a spoken node). The transmitter using the NK transmits the subscriber number of the dispatcher to the PBX, and after establishing a conversational loop by breaking it, it transmits a reporting code to the paired object.

The switch 1 has a manual switch for connecting to the subscriber line either TA 12 or the device (Fig. 5), as well as a group of relays P ₁ , P ₂ , P ₃ (Fig. 3), which are controlled by the control unit 9 and connect their contacts and the call signal receiving unit 5 (p1) is disconnected from the communication line, the call receiving acknowledgment unit (p2) 7, the telephone code receiver 6 (p3).

 The tunable descrambler 5 (Fig. 4) differs from the decryptors of the prototype by the presence of a decoding removable insert that controls the presence of a protective number in the report and gives the permission to decode the information part through the control unit. If in the adopted codogram the protective number (in our case 31) does not coincide with the number recorded by the decoding insert, the information is rejected and not accepted.

 The device for monitoring and controlling automated objects over telephone networks implements three operating modes.

 1. Automatic transmission of reports to the mating object (control room).

 2. Reception of the report at the control room in the presence of the operator.

 3. Automatic receipt of the request and control commands.

The first mode implements two operations sequentially:
dialing the subscriber number of the mating object and the formation of a conversational loop;
reporting code transmission.

In the automatic reporting mode, the device is turned on from the moment the sensor is triggered in the block 14 (Fig. 1) of the sensors. The signal is fed to the input of continuous monitoring circuit 1 (for example, at T ₂ — FIG. 2). The trigger T ₂ will work, the signal from which through the OR circuit will turn on the control unit 9 and open the key K ₁₂ in the programmable chopper 10, as well as the key K ₂₂ in block 3 of the tunable keyboard equivalent. The control unit 9 includes a pulse generator (Fig. 3), and the key K ₁ disconnects the call receiving unit 8 from the communication line. The shift register RG ₁ through the coding insert will record the subscriber number in the electronic dialer of the transmitter 2, which using the IR transmits a seven-digit code (2314106) to the PBX 13. After dialing the number, the control unit 9 will connect the call confirmation receiving unit 7 to the communication line. From the PBX 13, call confirmation signals will be sent through the switch to the call acknowledgment block 7, and through it to the control unit 9. If a paired object is formed (picking up the handset with a dispatcher), the receipt of call confirmation signals will stop. The control unit 9 disconnects from the communication line the call acknowledgment unit 7 and opens the key K ₂ in block 3 of the tunable keyboard equivalent, and closes the key K ₁ . RG ₂ begins to generate a reporting code (312), which the transmitter 2 will transmit the floor of the communication line. If, after the first transmission, the voice loop is not broken, then transmitter 2 will retransmit the message. After that, the device circuit is restored to its original state. In the programmable chopper 10, by opening the key K ₂₂ , the fact of the operation of the sensor N 2 is recorded.

In the case of occupying the number of the mating subscriber, the dialing and transmission of the subscriber number will be repeated a certain number of times (in our case 16), which is fixed by the counter CT. Each cycle ends in the 24th position of RG ₁ by applying a signal to the input of the dialer (#).

 If the line is not formed in a certain number of cycles, the transmission of the message stops.

 The second mode of operation of the device is implemented when the mating object performs the functions of a control center. The mode makes sense only in the presence of an operator who, using the key K (Fig. 5), is connected to the TA12 LAN.

 Having heard the ringing signals in TA12, the operator picks up the phone. Having heard the clicks in the phone, the dispatcher, after they are finished, disconnects from the TA12 LAN and connects the device by pressing the "Receive" button on the prefix. This operation is connected to the LAN by the control unit 9 through the switch 1 receiver 6 telephone codes.

The receiver together with the control unit 9 receives the telephone code signals bit by bit, but also the signals are fed to the input of the tunable decoder 5, the latter will fix the protective part of the reporting code (31), after this number coincides with the number encoded by the decoding insert, through the And circuit to the control unit 9 a signal will be given, the control unit 9 will open the key K, and the information part of the report will be received and decoded by DC ₃ . In this case, the corresponding LED (N 2) will light up on the display unit 4.

 A request and a control command are received by the device in the same sequence as when receiving a report, but the control command will be received only if there is a working sensor (for example, N 2).

 The request signals in the form of call receiving pulses are sent to the call receiving unit 8, to the output of which the input C of the programmable breaker 10 is connected. This connection is made only when the sensor is triggered. Otherwise, the reception signals of the call to the input from the programmable chopper 10 will not be received (key K of Fig. 2 is in the closed state). When four call signals arrive, the programmable chopper 10 will break the reception circuit using the control unit 9, and when they are received again in the eighth position of the chopper, the telephone code receiver 6 will be connected to the communication line, which will transmit the received signals to the tunable decoder 5, which will enable the corresponding decryption actuating element (Fig. 4).

 Thus, the device for monitoring and controlling automated objects is made in the form of a prefix, is connected to the subscriber line in parallel with any type of TA, and is used both at the control room and at the control object. The subscriber, having bought such a set-top box, is connected to the telephone network, to the sensors and actuators (Fig. 5). This allows him to organize mutual control and management with another facility equipped in the same way, using telephone network elements: telephone sets, automatic telephone exchanges, and communication lines.

 The presence in the device of the tunable block of the equivalent of a keyboard and a tunable decoder allows you to include n (n> 2) automated objects in the control and control loop, each of which can perform the functions of both a control room and a control object.

 The cost of the device (set-top box) does not exceed the cost of the telephone.
