Multifunctional (autodyne) application of Gann diodes allows to considerably simplify the schematic and design representation of devices. It means that the transmitter and transformer functions are provided at the same time with the amplification of useful .

Different working modes and frequency ranges allow to get an information about the kinetic and dynamic parameters and characteristics of moving objects with high precision when the autodyne signal is properly treated. The radio-wave autodyne EHF-band sensors with the length of 30-300 Hz on the high-effective Gann diodes and the production of the devices on their base with the consumer's properties hold much promise for the control systems (sub-systems) and for the control of moving objects.

The EHF-band sensors is used extensively in technological control process, metrology, EHF-radiography and science research by virtue of its contract-free design and high precision. [1-6].

The research and development results for the test-sample of radio-wave device vehicle for the movement parameters control “Express-TC” are given in the report. This device is designed for the express control of vehicle brake system in stationary (in the car repair stations, automobile factories) as well as in the road conditions.

The autonomous device consists of a portable receiving - transmitting three-beam monounit, brake pedal pressure sensor and central unit.

The radar monoumit is made on the basis of the autodyne receiving-transmitting modules [1] which are connected with the megaphone axis-symmetric antenna with 60 slope to every underlying surface and 35 turn of the second antenna from the plane passing through the first and the third antenna. The antenna aperture diameter is 50 mm. The dielectric lenses are hermetically installed in their opening which form the phase front of probing signals. The resonance system of autodynes is made on the segments of oval wave-transmitter. The high-efficiency Gann diodes “OXPA” (AAÝ768-D ADBK 432130.343 TU) are used as active elements with the low power consumption about 0,3 Wt in the power circuit. The working frequency of autodynes is set within the 41,3-43,4 hHz range which corresponds to the GOST 23450 - 79 (page 13).

As a sensitive element in the brake pedal pressure control, the tenzobridge ??? is used. Its signal increases and is transferred to the comparators that define the threshold signals for different brake modes (beginning of braking - the pedal pressure is no moreis transfsigsignals for different brake modes (beginningsigsignals for different brake modes (beginning of braking - the pedal pressure is no moreis transferred to the comparators that define the threshold ls for different brake modes (beginning of braking - the pedal pressure is no moreis transferred to the comparators that define the threshold tion at the end of the braking as well as the following characteristics: readiness (non-readiness) of the device to changes, speed correspondence to the normative value of movement; the control function of the device; execution of the re-recording for the normative value in the memory device or in the external IBM PC with the help of the connection unit. The control results of every vehicle are recorded by a recording register. This way it enables to input the data with the keyboard and print the vehicle model as well as its identification number. The central unit computer at the changing stage (for braking) receives the information about the doppler frequency of every channel. After the vehicle is stopped, the testing results are treated and documented as a record of the recording register with the summary characteristics of the braking system according to GOST 25478-91. It is done during the technical examination or under the road conditions, the record with the full characteristics of the braking system can be obtained including the print-outs of the brake diagram in the longitudinal and cross sections to analyze in greater detail the braking efficiency.

The design of the device “Express - TC” is done as follows: pressure sensor is superimposed and fixated on the brake pedals, the monounit of three beam autodyne radio-locator is hitched to the side surface of the vehicle body with a help of the magnetic system. The central unit and the autonomous feeding source are placed in the case.

According to the authors, the mentioned-above device with a corresponding design refinement offers a great promise for the cartography of the automobile and railway nets as well as for the design of transport taxographers to control the vehicle traffic schedule. It can also be a part of the locomotive autopilot on the basis of the overboard itinerary computer. It should be noted that the control of the movement parameters can be exercised during the movement even after it is stopped.
