The output of the second 10 and 11 third memory elements through a third element OR 31 connected to the fourth input of the encoder 8.

The device operates as follows.

If you need to check the condition of the distributor 4 with block 1 in the dispenser 2 is written formalized test message of the first type. It enters the distributor 4, and then in the channel module 5. Here it detected and deleted. At the same time this message comes in the key of employment of unit 6, where the data is stored on the degree of filling of the drive by categories of urgency that is part of the distributor 4. Upon detection of the first type a test message identifier in the employment unit 6 is formed of the signal that enters the encoder 8, and through the distributor 2 in block 1. By the received signal, the operator of block I / o 1 determines the state of the distributor 4. If you need to control the state of the channel module 5 unit 1 is formed a test message of the second kind. Channel module 5 detects this type of message and through the distributor 2 redirects it to the block 1. After passing the test message, the operator will make a conclusion about the defect is s five drives 15-19 and five drives 20-24. The original data in the drives 15-19 are entered by the operator. In the drive 15 is introduced encoded the period of time during which you want to block the source of the information block I / o 1. In the drive 16 is entered code sequence corresponding to the categories of urgency messages to be blocked with block 1 if overflow memory block into the distributor 4.

In the drive 17 is entered code sequence corresponding to the situation of unauthorized exposure to the distributor 4. In the drive 18 is entered code sequence corresponding to the situation of the accident (fault) in the dispenser in channel 4 or module 5. In the drive 19 is entered code sequence corresponding to the situation of accidents in the communication channel.

Source lock information for the specified operator of the program and the inclusion of spare blocks to repair the link is as follows.

In the drive 14 with the sensor 13 periodically (for example, with an interval of 1 sec) records the current time in the form of digital sequences in the binary code. At the transition point time values read IKI and unlock block 1. When matching the current time with the given work unit 12, the input signal which is recorded in the memory 20. In the proposed version of the drive 20 is presented in the form of a trigger, one input of which receives the signal of the beginning of the time block, to the second input - end blocking time. Therefore, the drive describe the situation contains two time values with signs "beginning" and "end". When the first coincidence signal output from the drive 20 blocks block 1, when the second coincidence happens unlock block 1 (see Fig. 3). This planned latch contribute to the smooth passage of, for example, messages from the other party involved in the control and management of communication that ultimately leads to the prevention of blocking of the network and, consequently, reducing recovery time communication. An embodiment of the drive control commands, including the drive 20 may be other, more complicated. The drive 20 may be implemented as a shift register connected to the decoder. The operator, having the ability to write to the drive 20 different code sequence (command) signal from the unit 12 may change direction is about to apply to drives 21-24.

Increasing information load messages of different categories of urgency is logged determinant of employment of unit 6. Let is sending messages to two categories of urgency is critical filling the drive into the distributor 4. In this case, the output of the determinant of employment of unit 6 produces a signal which is supplied to the first input of the encoder 8, where it is converted into a specific code sequence stored in the block 12. In the presence of this sequence in the memory 16 of the block 12 generates a signal for recording in the memory 21, the output of which is connected with one input element And 26. When passing through the distributor 2 messages of the second category the urgency of this message is detected by the analyzer 27, the output of which is connected with the second input element And 26. Element And 26 is triggered and produces a lock of this type of message in block 3. Unlock misconfiguring message is either to signal the operator that deletes the originally recorded information in the register 16, or at least release the drive into the distributor 4. Thus, in the interests of passing vysokokalorijnyh messages, the device blocks the entry in sector 4 the alarm will be triggered, as a result, the signal to its third output will be written into the element 9. Under the influence of this signal encoder 8 will produce a code sequence similar to the recorded in the memory 17. Will match two numbers and, as a result, the start of the drive 22. The drive 22 depending on the requirements of the system will generate 1 or N signals to run the shaper 32. In more detail the operation of the imaging unit 32 shown in Fig. 5. Service message with the specified address through the element OR 33 and the switch 30 is transmitted to the communication channel 1 or N times. Simultaneously with the formation of a service message through the element 25 is locked unit 1. Termination of the lock will either happen after you erase the information in the memory 17, or after resetting the alarm into the distributor 4. The distributor 4 and the block diagram is similar to the prototype. The third output of the distributor 4 (alarm) is associated with the design, and not with the logic of this dispenser. The signals from the fourth output of the distributor 4 and the control output channel of module 5 appear only in case of accidents of these blocks, so if a fault occurs in the distributor or channel 4 module 5 to the fourth input shirato in the memory 18. When the coincidence of these sequences in the unit 12 starts the drive 23, the output signal which will cause the trigger block 3 so that the information from the distributor 2 will backup path: allocator message 28, the channel module 29, the element OR 33, the switch 30. The translation device in the initial state according to the signals of the operator, after recovery (fault) in the distributor or channel 4 module 5. Hold switch 3 in a standby state at the expense of the trigger in the memory 23, the reset can be made only after recovery blocks 4, 5.

When determining the emergency channel, which is detected by the unit 7, the signal supplied to the second input of the encoder 8, formed a code sequence similar to the code sequence recorded in the memory 19. The coincidence of these code sequences starts the drive 24, the output signal of which, by acting on the switch 30, ensuring the passage of information through the reserve channel.

An example implementation of the memory 14 shown in Fig. 3. Suppose that a survey of situations is determined by three younger rogene at least one of the triggers 34, 35, 36, which are fixed in one of the schemes allocation fronts 38, 39, 40. This change is in this case time through the element OR 41 is transmitted to the input circuit And 37, which transmits the input information to the block 12. The principle of operation of the unit 12 (fragment) for the drives 15 and 34, 20 shown in Fig. 4. The memory 15 is a memory to record two time values and characteristics "start", "end" block. The latest signs provides a start or reset of the trigger 43. Interaction drives 16-19 with information received at the input unit 12 from the drive 14, is implemented via a scheme of coincidence (Fig. 4 not shown).

An example implementation of the imaging unit 32 shown in Fig. 5. The sensor 47 is triggered by the output signal from the memory 22, working a certain time, the duration of which is set by the timer 49. The sensor 48 generates a code sequence and through the element And 51 writes it in the register 50. A continuous sequence of pulses provides information read from register 50. The number of transmission retries is determined by the number of pulses from the second output of the timer 49, the input element And 51. In the proposed version of the drive 15-19 presented in the form of triggers, vosprinimaut the trigger.

An example of performing channel module 5 shown in Fig. 6. The selector 52 detects the messages belonging to a given channel, and the block error 54 has an output drive capacity of equal to the header of the formalized messages. Upon detection of a test message of the second type will trigger the analyzer 53, and will provide a channel switching unit output 54 or 55 to the input of the OR element 56. If a fault occurs in blocks 54 or 55 will control scheme 57 and failure alarms these blocks through the element OR 58 will enter the encoder 8.

The determinant of employment of unit 6 for two categories of urgency (Fig. 7) works as follows.

The analyzer 67 defines the category of urgency transmitted to the communication channel messages, making work relevant memory elements 65, 66, the output signal from which is fed to one input of reversible counter 59 or 60. To the second input of the reversible counter 59 and 60 receives signals read generated by the valve 4 when reading data in the communication channel, and trigger the reversible counter, category urgency message which will be read to that point. Actuation of the reversible counter 59, 60 on wnia amount of information in the memory allocator message 4 to the critical value will trigger the analyzer status of the counter 63 or 64 and the corresponding code sequence through the element OR 68 will enter the encoder 8.

An example run of the dispenser 2 is shown in Fig. 8. Test message with block I / o 2 through the register transfer 69 will go to block 3. With the appearance of the message in the register 69 analyzer 27 determines the category of the urgency of messages. The test message is passed along the transmission path through the distributor 4, channel module 5 through the OR element 73 is recorded in the register 70 reception. The analyzer 72, having found such a message, opens the key 71, providing output information in block 1.

The sensor local time 13 hours. Output signals in the form of an encrypted sequence current time enter in block 12. (56) USSR Author's certificate N 1197124, CL N 04 3/24, 1984.
