The invention relates to the field of computing technology and can be used for receiving telemetry information.

According to the main author. St. Ms 529454 Iave-rno input device ..

However, it is not reliable enough.

The aim of the invention is to increase the reliability of the device.

The goal is achieved by introducing a time selector and a quantizing signal generator, the input of which is connected to the output of the synchronization unit, and the output to the first control input of the input register. The input of the time selector is connected to the B1 formation input of the device, and the output is connected to the IEN formation input of the input register.

FIG. 1 shows a structural scheme of the device; in fig. 2 -. temporary chart of his work.

The device contains an input register 1, a channel selection block 2, an output register 3, a recording block 4, a synchronization block 5, a switch 6, a quantizing signal generator 7 and a time selector

The device provides the input of telemetric signals with time pulse modulation (VIM) to the recorder without intermediate, conversion of signals into a digital code.

The device works as follows.

The full telemetry signal (PTS) is fed to the information input .9 of the device, and the synchronization signals are fed to inputs 10 and 11. Input 10 receives a clock signal following information (Fig. 2), and input 11 receives a phasing marker,

During the operation of the device, the channel selection block 2 selects at the output the strokes of the channels selected for registration. FIG. 2p gate stub when selecting one of the channels. Such gates will arrive at the first input of reading the register information 1.

The input of the selector 8 receives the pulses of the TCP and interference. FIG. 2, two are shown: so-called and one measuring pulses, between them, square-shaped PTS pulses and one pulse — interfering-form pulses. The selector 8 selects pulses at the output (FIG. If) corresponding to the temporary fronts of the input pulses, Pulses c the output of the selector 8 is successively fed to the information input of register 1, the information that enters the input input of register 1, is entered into it in cycles of input pulses, which are generated by the quantization signal 7 formed (Fig 2). From the timing charts of FIG. 2, b and 2, d it can be seen that the duration of interference pulses can overlap 2-3 data input cycles in register 1 and, therefore, one pulse can be registered 2-3 times. Selecting only the front (} device input pulse times ensures unambiguous input of information into register 1. To eliminate device malfunctions, when changing input impulses for forms 1 of the transducer 7, information input of register 1 is closed. In this case, the formation is entered into register 1 with a delay of time duration of short pulses, After time tj (fig, 2f) driver 7 generates a polling pulse of register 1 (fig,;), the coincidence of the polling pulse with the strobe of the selected channel block 2 leads to the transfer of the first part of information, t, e, info from the register 1 to the register 3, under the influence of the signals of the synchronization unit 5 and the switch 6, the first part of the ilformapin ffxrue; block 1 perHcri.-iiiini, at the time of the registration of the juvenile section Cj (4ng, 2, 3) per-ifcrp 1 enters the nformaip of the T section after which the transfer of the third part of the information, and then the transfer of the third part of the information, etc. follows, etc. In FIG. 2, e shows four sections of t - 4 channel interval T of the selected canape. The information of each site according to the order of their follow-up is recorded by the registration unit 4 at the addresses that the synchronization unit 5 sets. The proposed device makes it possible to increase the reliability of the input of information by eliminating possible loss of information and its distortion due to impulse noise. formula of invention Device dp input information on the author. St. J 529454, characterized in that, in order to increase the reliability of the device, it introduced time selector and quantizing signal generator, the input of which is connected to the output of the synchronization unit, and the output - with the first control input of the input register, the input of the time selector is connected to information axo at the device, and the output - to the information input of the input register.
