Description

one

The invention relates to devices for recording, processing and transmitting information in telecontrol and telemetry systems and can be applied to compact the stored information in computers.

Devices are known for recording, processing and transmitting information about how long an object has been in possible discrete states, for example, for an object with n mechanisms in states: 5 °, all n mechanisms are working. Si - only one mechanism does not work, Sz - only two mechanisms do not work, and 5 - all mechanisms do not work, in which: signals of individual events determining the state of an object (an event, for example, consists in disabling any object mechanism), They are transmitted continuously from event sensors, for example, individual mechanisms, via several channels, the number of which is equal to the number of event sensors, to a device determining the residence time of an object in a particular state located at the receiving end; signals of individual events are sent to a device for forming possible states of pulses, which produces pulses of object states transmitted by pre-storing for a time interval in (n + 1) memory devices and sequential reading using a switch along a single channel.

A disadvantage of the known devices is either the need to transfer information simultaneously over several channels, which, with an extended communication line and a significant number of channels, makes the device more difficult and expensive, reducing reliability, or the need for simultaneous pre-storing, which requires a large number of memory devices and sequential reading. and the transmission of information causing some distortion of information.

The aim of the invention is to provide a device for the remote transmission of information on the duration of an object in discrete states, having a small number of channels and memory devices.

This goal is achieved by representing an object with a discrete set of inconsistent states, having a Poisson stream of events defining a particular state, like a waiting system with a single service channel, using a circuit at the transmitting end of the communication line. samples, the total number of events, the service time (time of occurrence of events), and at the receiving end of the device - a circuit for calculating using the above indicators of the object's residence time during the sampling interval GOVERNMENTAL discrete state x, connected to the recording instruments. The drawing shows a block diagram of the proposed device. The device includes equipment status sensors 1, drivers 2, first circuit OR 3, first counter 4, second circuit OR 5, pulse generator 6, second counter 7, reading unit 8, time sensor 9, analysis unit 10 , computing unit 11 and the registration unit 12. The device operates as follows. When signals are received from the sensors of the state of equipment 1 on one or several channels, simultaneously the driver 2 of each channel generates event pulses that through the OR 3 circuit arrive at counter 4, summing the number of event pulses. At the same time, using the imaging unit 2 and the second "OR 5" circuit, the presence of events are pulsed, which are quantized in time in the pulse generator 6 and then stored in counter 7. After the sampling time has expired, the time sensor 9 generates a pulse, which causes The readout unit 8 of the above indicators is operational, which provide data transmission to the receiving end of the communication line and resetting the readings of counters 4 and 7. At the receiving end of the communication line using the analysis unit 10 and calculating tion block 11 a determination probability, and hence, at a known sampling duration, the duration of residence of the object in a particular discrete state. In this case, in the case of the steady state mode, i.e., the constant mean values of A, i) 1, the computing device operates according to the algorithm for solving the formulas: I, ,, P ,, (k 2,3 p), Then in 6 PO TI Tai fi S w fs / i. where A, is the average number of events per unit of time, n is the number of possible discrete states of the object, q, is the inverse of the average duration of the event, PO is the probability of no event during the sampling interval, PI is the probability of the existence of a single event at the same time. The poison ft-likelihood of simultaneous k events; Tvb - the duration of the sample. Go is the duration of the object being in the absence of events, TI is the duration of the object being in the state when there is one event, TS is also when there are k events. From the computing unit 11, information about the values of To, T, TS is fed to the recording unit 12.
