The invention relate to communication technology and can be used for automatic control communication systems and communication channels for various purposes.A device for control of the communication channel, on the transmission side of which stands datalayer, the output block, shaper pulses of the frequency divider, the selector of the sixth pulse.The known device is used in the control system that is designed for calculation of the generalized parameters and assess the quality of the communication channel, but it is difficult to adapt to verify real communication systems in terms of real work.Known sensor control signal containing the pulse generator, the output of which through a distributor connected to the inputs of the decoder, amplifier, connected in series synchronization unit, generator control frequency switching unit and the adder, and block program management, and the outputs of the decoder through the block management software is connected to the other inputs of the switching unit, the output of the adder connected to the input of the amplifier and the other output of the pulse generator is connected to the input of the synchronization unit.However, the known device does not provide full control of modern communication systems.The objective of the invention is to enhance the functionality of the sensor control signals and improving the reliability of control.This object is achieved in that the sensor control signal is I and connected in series reference generator the synchronization unit and the synthesizer control frequency, the entered frequency Converter, the first input connected to the output of the synthesizer control frequency, and the output connected to the input of the amplifier, the attenuator high frequency signals, the input connected to the output of the amplifier, and the output is the output of the high frequency sensor control signal, connected in series modulator first input connected to the third output of the synchronization unit, the switch, attenuator intermediate frequency signals and the block matching, the outputs of the intermediate frequency which are the outputs of the intermediate frequency sensor control signals, the probing signal, the first input connected to the second output of the synchronization unit, and the output is connected to the second input of the switch block manipulation, an input connected to the first output of the synchronization unit, and the outputs from the second inputs of the modulator and probing signals connected to the system main unit programs the memory block tests, the display unit and remote control unit, input-output channels remote control and outputs readiness which are external inputs to the fourth output of the synchronization unit and the first output switch connected to the second and third inputs of the frequency Converter, respectively, and control outputs block the implementation of the programmes connected to the control inputs of the block manipulation synthesizer control frequency modulator, probing signals, the attenuator high frequency signals, switch and attenuator intermediate frequency signals.The proposed solution meets the criteria of the invention "novelty" because it differs from the prototype by the presence of new functionalities and new relationships between the elements.The sensor control signals can be used in the complexes due to the formation of the control signal (a control message, which in its structure coincides with the working radiogram) in real conditions of operation of the equipment, as well as for the organization of an automated health monitoring of technical means of communications systems and channels of communication for different purposes.In Fig. 1 shows the structural electrical diagram of the device of Fig. 2 is a plot of the voltages at the inputs and outputs of the individual elements of the device: (a) on the clock input of block manipulation; b) - the run command in the block of manipulation of the block the implementation of the programmes; - interrupt requests from the block manipulasi interrupt from the block manipulation when working in the mode of operation of the probing signal; W), and inputs a manipulation of the probing signal; C), K) outputs of the inverter-probing signal.The sensor control signal contains the reference oscillator 1, block 2 synchronization synthesizer 3 control frequency Converter 4 frequency amplifier 5, the attenuator 6 high frequency signals (HF), block 7 manipulation, the modulator 8, the switch 9, the attenuator 10-signal intermediate frequency (if) block 11 of the agreement, the imaging unit 12 of the probe signals, block 13 program implementation unit 14 local control unit 15 of the memory test block 16 of the display unit 17 of the remote control. All these units are connected as follows: 1-2-3-4-5-6, 2-4, 2-8-9-10-11, 9-4, 2-12-9, 2-7-8, 7-12, 13-14, 13-15-16-17, 13-7, 13-3, 13-8, 13-12, 13-9, 13-6, 13-11.The sensor control signal (BCS) is as follows.At power-BCS program starts self-control and after its implementation on the light display of the display unit and the output unit remote control (RC), you may receive the signal READY. When no signal is READY, you can run the program control unit (keypad of the local controls or through any channel remote control), which allows you to detect defective block is having a remote control. Channel group control allows you to connect to DKS multiple channels of interaction with various technical means complex communication, and when working with one of the technical means, which captured the interaction with the DQS on one channel control signals READY in the rest of the lines DN are removed, the remaining channels remote control can be operated only after the release of the previously used channel.At the beginning of the work vehicle, seized the canal DU BAC, enters a message on the control frequency, mode and speed, the magnitude of attenuation of the attenuators, test, the number of repetitions of the test case.The structure of the control signal issued by the BCS, is determined by the structure of the control test, previously entered in the BCS, and mode set, so before radiation it is necessary to prepare the test. For example, in the modes relative phase shift keying test is converted, it introduces relativity, in the modes intended for admission to the printing apparatus, the test structure added special characters, such as start and stop.The run command on output is ensured, the run command is removed.Channel DN is connected to the BCS technical tools, you can make a request and get the message about the installed options DKS, and to obtain evidence about the suitability of the BCS or failure of a particular unit.Block the implementation of the controller based on the serial microprocessor and comprising directly microprocessor, random-access memory in which is recorded the program, and random access memory, which is used by the microprocessor during operation of the program. At the outputs of block implementation of programs programmatically generates a set of control signals to the blocks DKC: sets the operating frequency synthesizer control frequency, the mode of operation of the modulator and probing signals, the attenuation of the attenuators RF signals and the inverter, the switching of the switch in the block manipulation code is set corresponding to the required speed Telegraph signal or the duration of the probing signal. The interaction of block programs with the remote control unit is performed by interrupt: any access to the BCS through the channels of the remote control which is abotu received messages. To the system main unit programs connected to the display unit, the remote control unit and the memory unit tests.On the light display unit display shows the current status of the BCS is the frequency value, the name of the mode and the speed or duration of the signal, the magnitude of attenuation of the attenuators, settings, control tests, information about the results of self-control.The remote control unit is made on the basis of serial transceiver designed for hardware implementation of the Protocol exchange with external technical resources, and interrupt controller interacting with the microprocessor unit program implementation. External inputs and outputs of the remote control unit and outputs readiness have galvanic isolation.In DKC unit installed memory tests, performed on the basis of the serial programmable permanent memory device, which allows a further stage of manufacture DKS to write tests for the most common and widely used control signals. In the process, it is sufficient to indicate the test number and the specified test will be prepared for radiation. Thus, to enter in the BCS control a TEC is t external hardware and keyboard of the local controls.Local controls allows you to set the parameters of the BCS directly from the keyboard, and the list of parameters of local governance coincides with the list of options remote control, including realized the opportunity for the input of control tests.The synchronization unit, the input of which is applied the reference signal generator generates the reference and clock signals to all units of the BCS, while providing high accuracy (better than the accuracy of the reference oscillator) all components of the output signal DQS: carrier if and RF signals and signal manipulation, which is especially important when using BCS in the complexes due to the formation of control signals in real conditions of operation of the equipment.The synthesizer control frequency, which is built according to the method of active digital synthesis on the basis of the rings phase-locked loop and managed dividers, forms a discrete grid of frequencies, which ensures the receiving the RF DQS signals, the carrier frequency of which varies in a large range and with a sufficiently small step, and the change range of the output frequency DQS corresponds to the frequency range of communications systems in cost, the designated use of the reference generator.In block manipulation of clock pulses (Fig. 2A) with an accuracy of the reference oscillator are formed timestamps that define the speed of Telegraph signal or the duration and repetition period of the probing signal for a specific operation. The START command (Fig. 2B) block manipulation generates a query (Fig. 2B, 2E) to block the implementation of the programs used in the block manipulation begins to receive a byte (with modulator) or bit (when operating with probing signals) test, which strobiles exact time stamps are converted to serial code and outputted to the modulator (Fig. 2G) or probing signals (Fig. 2ZH, 2i). The input control test query block manipulation continues until the end of the test and removing the run command.The modulator provides the formation of signals of the frequency, phase and amplitude telegraphy with various deviations and speed, as well as multi-frequency signal frequency and phase - frequency inverter. The list of modes of operation of the modulator covers the needs of the modern, as well as previously developed complexshape manipulation (Fig. 2G) at the output of the modulator is formed by amplitude-shift keyed signal at a frequency FC (Fig. 2D), where f1 is the carrier frequency of the output oscillations. In other modes of interaction with the block manipulation is analogous to the mode amplitude telegraphy.The probing signals provides at the output of the frequency-time structure of the probing signals that can be used to obtain information about the propagation conditions of the radio signals, which need to connect the output of the RF DKS at the input of the transmitter, available in complex communication, which will emit a short sounding radio (series of oscillations of high frequency), separated by large time intervals (pauses). The structure of the pulsed probe signal can be described by the following parameters: the duration of the pulse packet (t), the repetition period of packs (T), the number of pulses in a packet. The duration and repetition period of the probing signal with the required accuracy are formed in the block manipulation. The modulation signal enters the probing signals (Fig. 2ZH, 2i), which produces a pulse width modulation signal at frequency FC (Fig. 2H, 2K), where f2, f3...f6 - bearing Chav (Fig. 2i) with smoothly varying linearly with frequency, i.e., a bundle of impulses may consist of multiple short pulses, emitted at different frequencies (Fig. 2K). Changing the frequency of the if signal during receipt of each of the short pulses produced by the control commands received in the probing signals from the block of program implementation. The probing signals installed in the BCS, its structure is the high speed frequency synthesizer operating according to the method of direct digital synthesis, f3... f6 - changing signal frequency at the output.The spectrum generated in the modulator signals in the operating frequency range RF is transferred to the frequency Converter using the reference signal received from the synchronization unit. The frequency Converter consists of two categories: the first mixer between the output signal of the modulator and the synchronization unit, the second output of the first mixer and the output signal from the synthesizer control frequency. After the frequency Converter are broadband amplifier and attenuator RF signals, which provides a discrete signal attenuation of the RF.The group of outputs of the inverter intended the ditch, for their control, and, if necessary, for the analysis failed the technical means by changing the parameters of the control signal BCS. The block matching provides branching and electrical coupling of the outputs of the inverter DKS with external devices.DKS can be used to test communications systems do not have their own automated control. When this signal outputs the RF and if sections DKS are connected to the corresponding inputs of the inspected equipment, and control of the BCS is made with keyboard local controls.Thus, the proposed device allows the formation of the control signal, the same structure with the actual radiographs, pre (before the session) to check the operability of the equipment and the communication channel in real conditions, which increases the accuracy of control of complex communication.In addition, the ability to connect ABAC on the TV remote control to the automated communication system, and a discrete signal attenuation RF and if, the formation of Telegraph signals with different modulation types, including multi-frequency, formation of probing signals is o tests extend its own functionality. The sensor control signals containing the amplifier, connected in series local controls and block the implementation of the programmes and connected in series reference oscillator, the synchronization unit and the synthesizer control frequency, characterized in that it introduced the frequency Converter, the first input connected to the output of the synthesizer control frequency, and the output connected to the input of the amplifier, the attenuator high frequency signals, the input connected to the output of the amplifier, and the output is the output of the high frequency sensor control signal, connected in series modulator first input connected to the third output of the synchronization unit, the switch, the attenuator intermediate frequency signals and the block matching, the outputs of the intermediate frequency which are the outputs of the intermediate frequency sensor control signals, the probing signal, the first input connected to the second output of the synchronization unit, and the output connected to the second input of the switch block manipulation, an input connected to the first output of the synchronization unit, and the outputs from the second inputs of the modulator and probing signals connected to the system mA is s-outputs channel remote control and outputs readiness which are external inputs-outputs channel remote control and outputs the readiness of the sensor control signals, thus the fourth output of the synchronization unit and the first output switch connected to the second and third inputs of the frequency Converter, respectively, and control outputs block the implementation of the programmes connected to the control inputs of the block manipulation synthesizer control frequency modulator, probing signals, the attenuator high frequency signals, switch and attenuator intermediate frequency signals.
