Description

one

The invention relates to information transmission systems and can be used in adaptive telemetry systems.

Telemetry information transmission devices are known that contain an analogue converter — a code whose outputs are connected to a transmitter through a controlled buffer storage unit and directly to a controlled switch, as well as a synchronizer.

In order to increase the efficiency of using communication channels, in the proposed device, the outputs of a controlled switch are connected to the inputs of a level indication unit, the output of which, in turn, is connected to the inputs of the control signal generating unit directly and through a memory cell the memory cell is connected to the synchronizer, and the output of the control signal forming unit is connected to the control input of the buffer memory unit.

The drawing shows a functional diagram of the device.

The device contains an analogue-to-code converter 1, a transmitter 2, a buffer storage unit O, a controlled switch 4, a block 5 for determining the level feature, a block 6 for generating a control signal, a memory cell 7 and a synchronizer 8.

The signal about the simultaneous filling of several specific bits of the counter of the converter 1, corresponding to a certain number (level number), goes to

the transmitter 2 through the buffer storage unit 3, and through the controlled switch 4- to the level attribute detection unit 5, made in the form of a matching stage, the output of which is connected to the generation unit 6

directly and through memory cell 7 controlled by a synchronizer. The forming unit 6, in turn, controls the operation of the buffer storage unit 3. The operation of the device is as follows.

With the start of the measurement cycle of this parameter under the influence of a control pulse from memory cell 7, the signal of the cascade of coincidence obtained in the previous cycle arrives at the input of the forming unit 6.

At the end of the measurement cycle, the newly formed signal from the converter 1 through the controlled switch 4 and the matching stage enters the formation unit 6 and is simultaneously recorded in the memory cell 7.

Moreover, at the output of the forming unit 6, the signal controlling the buffer storage unit 3 is generated only when one of its inputs from the memory cell 7 receives the signal "O (in the previous

The measurement step of filling all "k controlled bits was not), and the other input from the cascade of the joint receives a signal" 1 (in this measure of measurement all "k bits are filled).

The proposed device provides for obtaining various and independent laws of the distribution of transmitted levels in the range of possible values, since this law depends on the specific switching of the controlled bits for each of the parameters. In this case, the transmitted levels can be located in this region both uniformly and with concentration in some zones. Changing the law is accomplished by selecting the appropriate transducer counter bits / by cross-cutting and can be automated, which allows this operation to be carried out during the measurement process.

The device can be used in existing telemetry systems for their

upgrades to provide automatic rejection of redundant information.
