The invention relates to quichemical engineering, in particular, to information Tsatsiorsho-measuring systems for oceanographic research, and 1 in the improvement of the device according to the author, no. 1277164.

The purpose of the invention is to increase the information content of the device. The drawing shows the function-1 | ion scheme of the device. I The device contains a switch 5 ,. register 2, fixed memory block 3 ;, n | first 4 and second 5 and third 6 comparison block 1, performed on the comparison element TJe 7 and HE element 8, NJeHT element 9, block 10 g (pulses executed on the forma- tion of 4 x 11 and 12 single pulses, bilok 13 RAM, arithmetic block 1, 14, and block 15 buffer ijoft memory.

1 The device works as follows.

 Switch 1, according to a preset program, connects the connected channels to register 2, which digitally records the current readings of the sensors. In addition, the switch 1 generates an address, according to i oTopoMy in block 3, the upper - and lower limits of measurement of a given physical quantity are recorded. The parameter value from the output of register 2 is supplied first, the inputs of blocks 4-6. At the second inputs of blocks 4 and 5, the comparison with the tynaroT terminal from block 3 is the upper and lower limit values of the change of the pa-) meter. To the second input of block 6, compare Yeni from the output of block 13 enters. The value of the previous count of the next sensor. If more than the current count, recorded in register 2j does not exceed the upper and lower limits of change, as well as the difference from the previous one, then at the outputs of the corresponding 4-6 comparison blocks, one-to-one signals are formed that arrive at the inputs of element I and 9 At the output of the element AND 9, a single signal is generated by the B-signal, by which the pulse shaper 1 generates a pulse that permits recording in

block 15 of the buffer memory received from the output of the arithmetic unit 14 is the difference between the current value of the reference, coming from the output of the register 2 to one input of the arithmetic eBlock 14, and the previous value of the reference coming from the output of the block.13 RAM to another input of the arithmetic block 14 ,,

On the trailing edge of the pulse generated by the shaper 11, the shaper 12 generates a pulse that permits the recording of the current reference value to the information block 13, which enters the information input of the main memory unit 13 from the register output 2, E (whether the current count received from sensor exceeds the upper or lower limits of change or does not differ from the previous value of the count, the difference between the current value and the previous value is not recorded in the block 15 of the buffer memory, and L is the value of the current parameter zanosits unit 13 RAM memory.

Thus, the proposed device registers not the absolute value of the parameter, but the value of its increment relative to the previous value, which significantly reduces the redundancy of information and improves the information content of the device.

 Arithmetical: the device is built on the IC 56 IPP, 564 IP4, configured to perform the subtraction operation.

The preloaded device allows a significant gain in saving the buffer storage unit.
