The structural scheme of the device represented in figure 1. Device modeling multimodal system includes a shaping unit operation program multimode system 17, control trigger 1, the block of the first operating mode of the simulated multi-mode system 2, the block of the second working mode of the simulated multi-mode system 4, block technological mode fashion the dummy multimode system 6, three meter operating time 3, 5, 7, block specify the duration of the technological mode of the simulated multi-mode system 8, the first and second blocks of generators of the random pulses 9, 10 (model failure when the multi-mode system in the first work and the second operating modes, respectively), the first random event generator 11 (models the occurrence of a failure when the multi-mode system in the technological mode), OR unit 12, the second random event generator 13 (simulates a random moment of recovery mode and multi-mode system), three counter failures 14, 15, 16.

The output of block job operation program 17 is connected to the input of the control trigger 1, the first output control trigger 1 is connected to the first input of the first operation mode 2, and the second output to the first input of the block second operating mode 4. The first output unit 2 is connected to the input of the first counter operating time 3, the second output unit 2 - a to the input of the first counter bounce 14. The signal from the third output unit 2 is input to the first block of random event generator 9. The first output unit 4 is connected to the input of the second counter operating time 5 and the input unit of assignment duration of the technological mode 8, the second output unit 4 with the input of the second counter from the Azov 15. The signal from the third output unit 4 is input to the second block of the random event generator 10. The first output unit 6 is connected to the input of the third counter operating time 7, the second output unit 6 - input of the third counter bounce 16. The signal from the third output unit 6 is supplied to the random pulse 11. The output unit 8 is connected with the fourth input unit 4 and the first input unit 6. The outputs of blocks of generators of the random pulses 9, 10 and the first random event generator 11 is connected with the second inputs of the blocks of the first and second operating mode and block technological mode, respectively, and the inputs of the block, OR 12. The output of block 12 is input to the second random event generator 13. The output of generator 13 random pulses is connected to third inputs of the blocks 2, 4 and 6, respectively.

The device operates as follows. The output of block 17 generates pulses whose shape is presented in figure 2, where τP1- the residence time of the system in the first operating mode, and τP2- in the second operating mode.

On the leading edge of the pulse control trigger 1 is activated and at its second output a signal, which is supplied to the first input unit 4 and translates it into an active state (thereby simulating the presence of multi-mode system in the second operating mode is IU). On the trailing edge of this pulse signal appears at the first output control trigger 1, which is supplied to the first input unit 2. When this unit 2 enters the active state, the signal on the first input unit 4 disappears and the unit 4 becomes inactive (thus simulating the transition multimode system from the second to the first operating mode). When transferring blocks of 2 or 4 in the active state at the first outputs of these blocks of a signal, which is fed to the inputs of counters operating time of 3 or 5. Counters operating time can be implemented as counters time intervals. In addition, when the activation unit 4 signal with the first output is to the input unit 8. The output of block 8 is formed by a rectangular pulse with a delay, the form of which is represented in figure 3, where τC- the length of the delay, τTr- the duration of the technological mode.

This signal is applied to the fourth input of the unit 4 and the first input unit 6. The leading edge of the pulse translates a block of 4 in the inactive state, and activates the block 6. When the transfer unit 6 in the active state at the first output signal appears at the input of the counter operating time 7, the purpose of which is similar to the counters 3 and 5. The rear edge of the pulse generated at the output of block 8, translates the block 6 in the inactive status is of and activates the block 4.

When you activate the block 2 from the third output of this block receives the signal on the input unit of the random event generator 9. At a random point in time at the output of the generator unit 9 a signal simulating a failure occurs in the first operating mode, which is supplied to the second input unit 2 and the first input unit OR 12. This stops the counter developments 3 and runs counter bounce 14.

When activated, unit 4 from the third output of this block receives the signal at the input of the generator unit 10. At a random point in time at the output of the generator unit 10 a signal simulating a failure occurs in the second operating mode, which is supplied to the second input unit 4 and the second input unit OR 12. This stops the counter developments 5 and runs counter bounce 15.

When you activate the block 6 with the third output of this block receives the signal at the input of the generator 11. At a random point in time at the output of the generator 11 a signal simulating a failure occurs in the technological regime, which is supplied to the second input unit 6 and the third input unit OR 12. This stops the counter time between 7 and runs counter bounce 16.

When the signal on any one of the inputs of the block 12 at its output a signal, which is fed to the input of the generator 13. At a random point in time is and the output of the generator 13, a signal occurs, simulating the time of recovery. This signal is applied to the third inputs of the blocks 2, 4 and 6, but is perceived only those of them, which is currently active. This stops the corresponding failure counter 14, 15 or 16 and starts the corresponding counter operating time 3, 5 or 7.

FIELD: measurement technology.

SUBSTANCE: method can be used for criminal and official inquires of road accidents. Method is based upon measurement of speed of pedestrian and calculation its arithmetical mean. Method differs from known ones, as speed of motion is measured experimentally 10 to 30 times with three different pedestrians having like age and physical condition as victim of run-over. Results are processed as small sample by using central deviations and those deviations are used to determine average meaning of speed of motion, standard deviation, error and truth of the average mean. Upon finding truth of average mean the necessary number of trials is calculated which number has to be compared with real number of trials. Additional trials are conducted if necessary. Factor of truth of experimental data is calculated from speeds of motion of pedestrians taking part in experiment. Probability and factor of confidence is determined accordingly to speed of motion of injured person and speeds of motion of pedestrians involved into experiment, as well as according to truth of preset limit values of this parameter. If values of preset factors correspond to legitimate values or limits admitted for investigation of road accidents, statistically true minimal and maximal values of speed of motion of injured pedestrian are calculated on the base of normal distribution law by means of subtraction the speed from its average value and addition of product of factor of confidence with standard deviation. Limit values of speed of motion of injured pedestrian are presented for forensic examination to make calculations determining availability or lack of availability of prevention of run-over. For this purpose the statistically truthful minimal and maximal values of speed of motion of injured pedestrian should be calculated in relation to accessible values or limits of probability which is higher than 0,95 and if confidence with speed of motion of injured pedestrian and pedestrians involved into experiment correspond to each other. Preset precision of pedestrian's speed of motion should be within limits of +-0,5 km/hour.

EFFECT: improved precision of measurement; higher probability of prevention of road accident.
