Description

The invention relates to radio electronics and can be used in monitoring the parameters of autonomous objects for registering irregular and relatively rarely repeating processes or modes of operation under conditions of time and number of communication sessions with means of control and management. A device for selectively monitoring telemetric parameters is known, comprising a switch, the output of which is connected to the first input of the comparison unit and the first input of the message recording unit, the second input of which is connected to the output. The resolution of the comparison unit, the second input of which is connected to the first output of the memory unit, the second output of which is connected to the first input of the decoder and the third input of the message registration unit, the fourth input of which is connected to the output of the time sensor, the third output of the memory unit is connected to the input Switch ij. The disadvantage of this device is the impossibility of making more detailed measurements of telemetry parameters after they go beyond the limits (control levels). The device for selective control of telemetry (TM) parameters containing a switch, the output of which is connected to the first input of the comparator and to the first input of the message logger, the second input of which is connected to the output of the comparison block, the memory block, the first output of which is connected to the first input of the desh and the third input of the message recorder, the fourth input of which is connected to the output of the time sensor, and the second output of the memory unit is connected to the input of the switch, AND elements, delay elements and key elements f2l However, the known device also has a low control accuracy due to the fact that, providing control of TM parameters on the principle of a norm is not a norm, it does not allow making more detailed measurements of them, for example, after going beyond the limits of norms (after crossing the Komol levels), the need for such control occurs, for example, when the telemetry object has a repeat to cix with relatively short-term modes of operation or when measuring transients. Providing a more detailed than the norm-not-norm parameter control parameter requires the installation of an additional TM device at the facility, which is not always advisable. The purpose of the invention is to improve the control accuracy by taking into account changes in parameters outside the control levels. The goal is achieved by the fact that a device for selective monitoring of telemetric parameters, containing a switch, the output of which is connected to the first input of the comparator and to the first input of the message recorder, the second input of which is connected to the output of the comparison block, memory the output of which is connected to the first input of the decoder and to the third input of the message recording unit, the fourth input of which is connected to the output of the time sensor, and the second output of the memory unit is connected to the input of the switch, S, AND, delay elements and key elements, a control level change block is entered, the first input of which is connected to the third output of the memory block, the output is connected to the second input of the comparison block, the input Extend extension is with the output of the comparison block, the input Decreases the tolerance - with the key outputs elements, whose control inputs are connected to the inputs of the delay elements, with the first inputs of the elements And, and with the outputs of the decoder, while the I1 inputs of the key elements are connected to the outputs of the delay elements, the reset inputs of which are connected the outputs of AND gates, whose second inputs are connected to the output e of comparator unit, and a second input of the decoder - a second vkodom memory block. FIG. Figure 1 shows the structural electrical circuit of the device for selective control; Fig. 2 shows the time diagrams of its operation (Fig. 2a shows the polling pulses; Fig.26 changes the monitored parameter and its tolerances; Fig. 2c shows the recorded values of the parameter). The device contains a switch 1 / block 2 of memory, block 3 comparison. 3, sensor 4, time, block 5, registration of messages, block 6, changes in koiterrol levels, decoder 7, elements AND 8, delay elements 9, key elements 10. The device operates as follows. A program from the second output of memory 2 to switch 1 and decoder 7 interrogates the sensors connected to the inputs of switch 1. The memory of decoder 7 stores the addresses of those parameters that are subject to more detailed control than the norm control. - not the norm. The distribution of the polling pulses according to the outputs of the decoder 7 is performed depending on the addresses received at its other input from the first output of the memory block 2. The address of a certain parameter corresponds to one specific chain, consisting of AND 8, delay element 9, and key element 10. The event sensors are shown from the output of the switch. 1 is fed to the 3 comparison input and compared there with the corresponding control levels coming from memory block 2 via block 6 of changing control levels to another input of comparison block 3, When the control crosses its control level (Ut, jo), comparison block 3 extracts the resolution signal, . arriving at block 5 of the registration of messages, at the input of the extension of the tolerance of block 6 of the change in control levels and at the first inputs of the elements OF; In block 5, the registration of the event occurred with recording the time coming from the sensor 4 time. Block 6 of the Change of Control Levels by Signal Resolution provides an increment (Fig. 26 of the corresponding control level coming from memory block 2, t, e, in the next polling cycle (Fig. 2a) the current value of the parameter will be compared with the increased by some predetermined discrete 55 - 4 value by the control level (,). When the parameter crosses the control level U | fu, block 6 provides an increase in the control level to and (|, Oh, etc., until the intersection of changes changes to admission The parameter of the tracking level of the control level, All intersections of the control level are recorded in message recording block 5 (FIG. 2b). On the And 8 elements, the signals coincide. Resolution with the output signals from the decoder 7, resulting in a signal from the output of the corresponding And 8 element to the reset input of delay element 9 performed, for example, in the form of a shift register, will reset it to the zero state. The magnitude of the time delay is chosen based on the required accuracy of control of the corresponding parameter. By filling in the delay element 9, a signal appears at its output, which opens the key element 10 and passes the next interrogation signal from the output of the decoder 7 to the input. value for each polling pulse to its intersection with the parameter level. The moment this is recorded in block 5, and the control level by signal. The resolution is increased by one artifact value. The moment the parameter enters the limits of the norm (intersection) of the KOHTpoJibHoro level) is also recorded, after which no further change in the control level for this parameter is made. Thus, by registering a change in a certain number of parameters outside the stationary control levels U | f, | corresponding to them, an increase in the accuracy of the controlled object is provided.
