Converter 6 parallel code in a sequential contains the input unit 22, the register 23 of the reception code commands, the register 24 of the reception code address register 25 of the code issuing addresses, block 26 control, eight-bit register 27 of the code issuing commands, sixteen-bit register 28 issuing consistent is consistent code the decoder 31 addresses of subscribers receiving serial code amplifiers 32.

The system works as follows. In accordance with a set program of tests in the PC 16 is loaded packages test programs in computers 9 input the input to the program. In accordance with these programs are sampled control points of the test object 21 and compared with the allowable limits. The results of the measurements and the control algorithm is checking the operation of the test object 21. The control system incorporated in the personal computer 16 provides as managing direct hardware control object 21, and management simulators environment, causing the impact on the test object 21 close to the real conditions of operation. Converter 2 collects information from various sensors of the test object 21: sensor output voltage from 0 to 6, a temperature sensor, a signal in the form of a circuit dry contact or an electronic key. The information obtained is converted into a digital code. The voltage sensors are encoded in eight-bit parallel code using a Converter 2 analog-code, and the signal sensors are combined in volmerswerth 6. Inverter output 2 information supplied to the Converter 6 with a frequency of 80 or 40 kHz, where it is converted into a serial code. The control signals by the Converter 6 come from the PC 16 via the transceivers 14 and 13, the connection unit 12, the unit 10 I / o through line sharing 18. The information obtained in the Converter 6 is supplied through the block 10 in DCM 9, where the comparison of obtained data with the reference. According to the results obtained information the CVM 9 through the block 10 in accordance with the selected algorithm generates control signals to the inverter 6, which issues control commands in the form of codes to the decoder 7, which then issues control commands to the test object 21 in the form of a relay closure time of 0.1-0.9 with directly through the switch 1 or through the block 8 electronic keys with controlled duration outputs through which the switch is connected to the corresponding inputs of the test object 21. The team managed duration comes to amplifiers commands the test object 21, and then directly into the system. Commands in the control object may also be sent directly via the information channel from the CVM 9 through the block 10, the highway interchange at highway interchange 20, unit 17 pairing, which converts the code interface type Manchester-2" in the code interface type "salute" and then through line sharing 18, block 10, DCM 9. Highway exchange 20 and the block 17 pairing is required in this system for application in the object control interface, Manchester-2" (the Interface of the ice GOST 2676552-87), which currently has a wide application in space communication systems. Machine-to-machine communication on-Board computers control object and CUM ASC is provided through a buffer storage unit 5, which represent two halves of a RAM write access to which is made only from its zone. The information read from the block 5 is provided with any of the computers on both halves of RAM. Communication on-Board computers of the test object 21 (not shown) and DCM 9 ASC with a personal computer 16 through the block 12 pair, in which the conversion interfaces "salute" from the onboard computers of the test object 21 and the CVM 9 ASC in a single interface "Q-BAS". The converted information on the General highway interchange 19 is supplied to the transmitting part of the transceiver 13 is converted into an optical fibre-optic 15 is transmitted to the transceiver 14, where the inverse transform in elektricheskaya means test. Block 11 receives a frequency of 1 Hz and 125 Hz in the block 10 and a frequency of 1 Hz in block 12 pair for the current time and the integral time. Blocks 3 and 4 are required for amplification of the signals of the interface "salute" from the test object 21 to the ASC and Vice versa, because the ASC is located at a distance of 30 m from the test object 21. FOCL 15 transceivers 13 and 14 is applied to increase the noise immunity of the signals from the PC 16 and remove the PC 16 from the test object.

The operation of the transducer 6 of the parallel code in the serial is the following. Information word in the form of bipolar parallel two-byte words transmitted from the unit 10 on the transformer inputs driver input unit 22, where the formation of the signal amplitude 4-6 in patibility unipolar signal. The generated signal is sent to the registers 23 and 24, the output of which command codes are received at the register 27 and output in the form of successive eight-bit code is supplied to the amplifier 32, where increases from 5 to 6-10, and formed a duration of 1.5 to 4 MS. The generated signal from the output of block 22 through the register 24, the register 28 is supplied to the decoder 30, which signal control unit 26 issues with the, the.E. two signals are input to the decoder 7, and one signal of the control input of the Converter 2 analog-code. Inverter output 2 signal as a sequence of sixteen-bit code is supplied to the inputs of the respective amplifier 32 and through the decoder 31 under the control block 26 control is transferred to the input register 29, the output of which through the register 25 is supplied to the inputs of the input unit 22, where the gain of the signal output circuits for dual transformer output and then double-byte parallel code is supplied to the unit 10.

This ASC is built on the principle of multi-machine exchange, which greatly improves the reliability of process control, diagnostics and control. The number of removed points of control can be more than 4096. Proposed ASC also has self-control. Each block ASC made in the form of a module that provides the change in the number of monitored parameters as in the direction of increase and decrease, depending on the configuration. The advantage of this system is that as the PC uses a personal computer wide application type VMRS/ATA developed peripheral is currently has wide application in the system space objects.
