Description

The invention relates to information-measuring equipment and can be used in operational control systems' aircraft.

. The purpose of the invention is to provide an increase in the amount of information recorded during the flight.

The drawing shows a block diagram of the proposed device for collecting and recording flight information ..

The device contains a block of 1 sensors, a block of 2 analog-to-digital converters, a block of 3 synchronization, a group of 4 elements OR, an element OR 5, a group of 6 elements AND, an element AND 7 _; +1) -bit shift

register 8. The outputs 9 of the sensor unit are connected to the information inputs of the unit 2 analog-to-digital converters, the control input 10 of which is connected to the first output of the synchronization unit 3. The first inputs of the elements of OR group 4 are connected to the corresponding bits of the output 11 of block 2 of analog-digital converters, the second input of the first element OR of group 4 is connected to the second output 12 of block 3 of synchronization, the second inputs of the remaining elements of OR of group 4 are connected to the bus 13 of zero potential of the device . The third 14 and fourth 15 outputs of the synchronization unit 3 are connected respectively to the first and second inputs of the element OR 5, the output 16 of which is connected to the first input of the element 7. 7. The fifth output 17 of the synchronization unit 3 is connected to the first inputs of the elements

And group 6, the second input element And 7 and the input entry (<| +1) -bit shift register 8. The outputs of the 18 elements OR group 5 is connected to the second inputs of the elements And group 6, the outputs '19 of which are connected to <| information inputs (<[+1) -bit shift register 8 (<} +1) -th information input of which is connected to the output 20 of the element And 7, the output shift - with the sixth output 21 of the synchronization unit 3, and output 22 with the output of the device.

The structure of the data formation at the output of the device is constructed so that each of them is accompanied by a clock sync signal, the beginning of each measurement cycle was distinguished by a frame "Sync signal, the beginning of each. The tenth measurement cycle is marked with a subframe sync signal, and the change is a minute time mark.

The device works in the following 5 ways.

In block 3 of synchronization, the code of the number of the connected measuring channel (sensor) is formed, the information necessary for identifying flight data in the form of clock, frame and subframe clock pulses, a minute time stamp, and shift frequency pulses.

channel, the value of the parameter obtained from one of the sensors of the Sensor 1 block is converted in block 2 analog-digital converters into parallel-digit digital code _l which from the output 11 of block 2 analog-digital converters goes to the first inputs of the elements of OR group 4. tied

25 to a strictly defined position in the frame and appears at the output 11 simultaneously with the clock synchronization signal at the output 17 of the synchronization unit 3. The minute time mark from the output 12

30 is fed to the second input of the first element OR of group 4 and is entered into the free position of a position in the frame containing the code of units and tens of hours. The second inputs of the remaining elements OR of group 4 are connected to the bus 13 of the zero potential of the device. The frame and subframe sync signals are assigned to different positions, spaced apart in time and collected from

df outputs 14 and 15 of block 3 synchronization element OR 5, from the output 16. which these signals are fed to the input element And 7, in which they are gated using a clock sync signal obtained from the output 17 of block 3 synchronization. Ana-. logical gating is performed with a data code and a minute time stamp using AND elements located in the element group

5 ° AND 6, where the information comes from the output of the 18th group of 4 elements OR. Thus, the stage ends with the conversion of a (^ 4-η) -bit parallel code into +1) -bit.
