SU708520A1 - Device for selective monitoring telemetry parameters of stationary and moving objects - Google Patents

Description

the torus, the second input of which is connected to the second output of the memory unit, the output of the decoder and the output of the switch are connected to the first and second inputs of the memory of the address code, the first output of which is connected to the fifth input of the message recording unit, the sixth input of which is connected with the output of the additional Switch, the input of the latter is connected to the second output of the memory of the parameter address codes.

The drawing shows a structural electrical circuit of the device for the selective monitoring of telemetric parameters of fixed and moving objects ..,

A device for the selective monitoring of telemetric parameters of stationary and mobile objects contains switchboard 1, memory block 2, block 3 is compared with r. time sensor 4, message recording block 5, additional switch 6, memory block 7 of parameter address codes, decoder 8 and switch 9.

The device works as follows.

From block 2 of memory, switch 1 receives a sequence of addresses (polling program / ma), B according to which switch 1 performs a sequential interrogation of telemetry sensors (not shown) connected to its inputs, and issuing a value of the next telemetric parameter to the input block 3 comparison. At the same time, control levels corresponding to this telemetry parameter are received at the other input of comparator unit 3 from memory unit 2.

In the case of detection by block 3 of the comparison of the fact of a transition by the signal of the control level, it generates a resolution signal issued to the message recording block 5, which, by this signal, goes into the message generation mode. Simultaneously with the signal the resolution of unit 3 of the comparison 4 normalizes and outputs the signal processing to the switch 9 and decipher 1xp 8.

By this signal, the decoder 8 decrypts the address of the parameter currently being analyzed coming from block 2 of memory to the decoder 8, and switch 9 issues a signal to block 7 of memory of the parameter address codes. which organizes a subroutine of selection of related parameters, for which it issues to the additional switch 6 the codes of the addresses of the parameters contained in the organized subroutine.

At the same time, these address codes of the corresponding parameters are received in message registration block 5 for issuing them as part of a message. From the additional switch 6, the values of the accompanying parameters, which are also INPUTTED to the message, also arrive at the message registration block 5. The message structure also provides for the time code, which is entered into the message by the message recording unit 5 from the time sensor 4 by a resolution signal.

Thus, the signal message generated by the device consists of the code of the parameter address, which went beyond the control norm, the time code of fixing the fact of the parameter’s exit for the check norm, and the codes of the values of the accompanying parameters with their addresses.

Introduction to the message of the accompanying parameters, selected in accordance with special programs, allows using the extremely limited amount of telemetry information to quickly and fairly fully determine the reason for the output of the analyzed parameter for the reference rate | make control, groups of parameters defined by the program, when one of them changes; to have additional data to the sensor information of the operating state of the object, which allows the prediction of the state of the object as a whole.
