In block 14 is introduced conditional number N of the mobile station, the control which must be done, and the current value of the sign of the presence of cycle control SK. If SK = 0 (loop control not), and introduced the conditional number of the mobile station N, it generates a command to activate the transmitting device 1 VR and signal station numbers SN are received by the input unit 14 and are inserted in the transmitting device 1.

A simplified block diagram of the speed meter 25 is shown in Fig. 3. The speed meter 25 is composed of series-connected first formirovaniia device 27, schema matching 28, the pulse counter 29. Crystal oscillator 31 through the second formirovanie device 30 is connected with the second input circuit 28 matches.

Adders parameter values 33 and 38 are connected by cross-links between them. The outputs of the first and second channels connected to the first and the second input of the adder with a threshold device 42. The identification block 26 operates as follows. The signals at its input comes from measuring the power level of 21 and a speed meter 25. Amplifiers with adjustable gain Ky132 and Ky237 are configured in accordance with the magnitude of the correlation coefficient between traits. In the adders parameter values 33 and 38 characteristic values are summed, and then averaged in the equalization tank parameter values 34 and 39, amplified quadratic amplifiers 35 and 40, are normalized relative to the reference characteristic values Zi and Zj in amplifiers with normirovanie coefficientsa comparison operation with a threshold decision. At the output of the identification block 26 are formed components of the vector characterizing the value function of the distance Yong. Estimation of the probability of parametric protection controlled radios can be determined on the basis of the ratio

PPZ= 1-[Pto01]Yong(1-Pto01)n-Yong,

where P01the probability that K-th digit code sequence consisting of n bits, at a given point in time or information item, or null.

Pto01= Pm1(1-P1)1-m,

where P1- the probability of unit K-th category m is a number equal to one or zero.

For the case when the estimates of the parameters of the radio are represented in digital form in the form of n-bit code identifying the characteristics of the controlled radio, you need to compare code sequences of estimated information parameters radios and reference radios and on the basis of the linear crucial functions to decide the similarity of these code sequences.

In Fig. 4 presents the dependence of PPZ= f(EN) for n=5 and Tr is the metric of security radios increases with decreasing function EN.

The device operates as follows. In the initial state of the second driver control signal 6 outputs control input of the second control attenuator 4 signal at which its attenuation is minimal. When applying a control signal to the driver of the start signal 20 (to be carried out by the operator of the mobile station enables transmitting device 15. The power and frequency of the signal emitted by the radio device 15 is measured by measuring the power level of 21 and a speed meter 25. Power value and frequency meter power level 21 and speed meter 25 is fed to the input of the identification block 26, in which the evaluation of the measured information of the parameters of the controlled wireless device 15 and a decision is made by comparing the results of the mathematical descriptions of the controlled and reference radios. From the output of the identification block 26, a signal is generated on the imaging unit to run 20, which generates a command signal as a function of the system. The signal containing information about the serviceability of radio transmitting device 15 from the output of the shaper teams start 20, via the OR element 18, is fed to mouchiroud receiving device 2 fixed station, outstanding receiver commands 10 and the control transmitting device 15 is recorded in the recording unit 13. Then, the control unit 9 is transmitted command, which enables the driver control signal 8, and the power command control signal 8 is also provided on the processing unit numbers station 14 and the first driver control signal 5, and through the delay times TD, determined by the delay element 7, is included in the second driver control signal 6. Driver control signals 8 includes a radio transmitting device 1, the carrier frequency which is modulated by the control signal. The output voltage of the first driver control signal 5 linearly increases, this decreases the attenuation of the first controlled attenuator 3, and thus gradually increases the size of the emitted stationary power station. The control signal is received radio receiving unit 23 of the mobile station, the receiver control signal 16, and upon reaching the input signal level sufficient to trigger the threshold unit 17, the output of the last, and therefore on the output element And 22 receive the signal including the driver signal of the first driver control signal 5 through time, determined by the delay element 7, includes a second driver control signals 6. The delay time should correspond to the sum of the time required by the mobile station to switch from receive mode to transmit mode, and the operation of the receiver station numbers 12. The output voltage of the second driver control signal 6, is regulated by attenuation of the second controlled attenuator 4, that is, the change ratio of the transmission signal from the antenna to the receiving device 2. If the gain-controlled radio receiving device 23 corresponds to the norm, the number of the mobile station is received at the stationary station and decoded by the receiver station numbers 12 with the high value of attenuation of the second controlled attenuator 4, which with proper transmitting device 15 corresponds to the signal level at the input of a receiving device 2, below threshold threshold unit 11. In this case, the recording unit 13 records the health of the receiving device 23 and the check number of the mobile station. If the sensitivity of the receiving device 23 is below normal, the tripping threshold of the block 17 is at a higher level CSOs controlled attenuator 4 in this case is smaller and decoding non mobile station at the output of the threshold unit 11, a signal is generated, proving fault check receiving device 23, which is recorded in the recording unit 13. In addition, room controlled at a given time station from the output of the signal receiver station numbers 12 enters the processing unit numbers station 14, where it is stored. This is how the inventive device when removing control from the mobile station control on the initiative of the mobile station). When the control from the fixed station device operates as follows. In the processing unit numbers station 14 is introduced through the third entrance) conditional number of the station, the control which must be done. Block number generation station 14 monitors the presence of a signal at the output of the driver control signal 8 (sign SK). In the absence of the control loop (SK=0), the output processing unit number signal station 14 to the input of the transmitting device 1 receives a command to activate the transmitting device 1 to the radiation (VR) and introduces a number signal controlled station (SN). The number signal controlled station output radio transmitting device 1 through the first controlled attenuator 3, corresponding to an antenna device and station 24, where there is a comparison of the received identification numbers with the number assigned to the mobile station. If the numbers match, then the receiver output signal station numbers formed the team that arrives at the input of the shaper run 20 and includes it. Further, the device operates as well as in the management control of the mobile station.

In the case of cycle control (SK <>0), the block number generation station 14 through the delay times TD" provides a new cycle control characteristic SK. And if SK=0, then the operation of the device is performed as described above. The delay times TD" is selected equal to the maximum cycle time control of one of the rolling object.

Feasibility advantage of the claimed device in comparison with the prototype is to improve the quality of functioning of a radio communication system on the basis of the estimation using the block identification parameters and the structure of the system by a set of signals emitted by a radio station. And technical state controlled radio stations quantified. The results of the quantitative evaluation can be taken concrete measures to enforce compliance of izmest radio exclude mutual interference.
