Description

one

The invention relates to magnetic measurements, namely, devices for measuring magnetic field parameters. Magnet-variance stations and K T Mr 5 are known with a setup for storing digital data from the ATRTGP I. These instruments are magnetometers with a record of the total value of the magnetic field and time / adapted to measure variations of the magnetic field.

A disadvantage of the known device is low speed.

The closest in technical essence to the proposed device is an MMVS marine magnetic variation station, containing a series-connected magnetically sensitive block. Amplifier - measuring unit with an output register, ape counter, program device, electron switch, and recorder 2.

However, in this device a large amount of data is recorded on the tape of the recorders, carrying almost no information. So, for the MBC and iAMBC stations, in each cycle it is necessary to register 8 or 12 binary information, the corresponding bits, respectively, while the information in most

The cases from cycle to cycle only change by one to two binary bits. The redundancy of information organizes, on the one hand, speed, and, on the other hand, the time of continuous recording of information without changing the tape recorder.

The purpose of the invention is to increase speed.

This goal is achieved by the fact that a magnetically sensitive unit and an amplifier - measuring unit with an output register, a time counter, a serially connected program block, an electronic switch and a recorder are connected in series to a magnetic variational device with digital information recording, a second unit of the program device is connected to sequentially connected census register, a block for detecting changes to information, a counter and a block to mmutatsii with register memory, wherein the output unit changes the detection information is connected to the second input unit KSM mutations with register memory whose output is coupled to the input elektronku switch, and an input unit

the initial data, the first input of the last is connected, with the output of the amplifier measuring unit with the output register to the input of the census register

codes - and the output of the input block initial

The data is connected to the third input of the commutation unit with a memory register.

The drawing shows a block diagram of the device.

The device contains a magnetosensitive unit 1 amplifier-meter; ШW unit 2c output register 3 ,. code census register 4, block 5 for detecting information changes, counter 6, initial data block 7: switching unit 8 with memory register, program block 9, time counter 10, electronic switch 11 and recorder 12,

The device works as follows.

The magnetically sensitive unit 1 and the measuring unit 2, the components of the magnetometer itself, convert the values of a measurable magnetic field into a digital code. Yagnito meter & pushes off - Data at the end of a clock is rewritten to the output register 3 and stored there about receiving new data at the end of the next clock. The operation of the magneto-magnetic: -th station is controlled by a program block.

9, which is also available in the emeinka label, received by the time counter

10, Information is recorded in arrays. At the beginning of the beginning of the array, the service information, the start time of the array and the complete start, the HSMepssKoro field of the magnetic field, are recorded. This initial information is framed using the initial input data block 7, which is sent by the command from the program block 9 to transmit the data from the switch block 8 to the memory transmitter to the recorder 12. Simultaneously with the transmission of the code 1 value The measured magnetic field from the output register of page 3 is transmitted to the initial data input unit 7 at the end of the first clock of this array, the same code is written to the register 4. After the second clock is completed, the block 5 detects information about changes in a--. of conducts a comparative analysis of the nn-formation recorded in registers 3. 4p i. information received in the first and second bars. Block 5 you can see the Research Institute of Information Changes can be performed, for example, from comparison schemes of codes (by the number of bits of registers 3 and 4), matching schemes on .O and. by 9 {when the device is operating in a double-decimal code), memory cells and logic circuits. If, according to the results of analysis4, it turns out that in the second cycle, compared with the first one, the information has changed only in the last lower order bit, then the code of the lower bit of register 3 through block 5 and further through block 8 of switching with memory register and electronic switch I ne is transmitted to the recorder 12 .;

If the Changes in information occur in the penultimate or penultimate and last bits, then the data of the two lower bits and the like are transmitted to the recorder. Upon completion of the analysis and transmission of data to switchboard unit 8 with a memory register, the code from register 3 is rewritten to register 4. At this, the cycle of analysis and transfer of codes in this cycle is completed,

In the third and subsequent cycles, the indicated operations of analyzing and transmitting codes are repeated, the information obtained in this clock is compared with the information received in the previous clock, and data from those bits in which, compared to, are transmitted to pei HCTpatop by the preceding measure, npoHSOTffliH changes.: The initial information and the information obtained) in separate cycles, are separated by a special separator character, the fuzz edge by the 8 cmmutation unit with the memory register
