SEMI-PASSIVE MOBILE OBJECT IDEPTIFICATION SENSOR

The proposed utility model relates to the field of control and management and can be used to obtain information from moving objects.

It is known that the outdoor device containing the power supply and generator control unit with an information output unit connected to it consisting of a generator and a receiver with a receiving antenna, and an inductor with a transmitting antenna connected to a generator (US Pat. RF No. 20033544, cl. IPC B61L25 / 02, published on November 30, 93, Bulletin No. 43-44).

The disadvantages of this device are the possibility of failure of the power supply due to long operating modes, as well as the possibility of causing damage to the health of others.

The technical task of the proposed device is to increase the reliability of the device and eliminate hazards to human health.

This object is achieved in that in a semi-passive code sensor for identifying a moving object, comprising a power and control unit connected to an information unit equipped with a transmitting antenna, a receiving antenna, a voltage converter is connected in series, to which a receiving antenna, a detector, an information processing unit connected to the power and control unit; wherein the information extracting unit includes a series-connected code generating and recording unit and a transmitter, in which case the code generating and recording unit is connected to a power and control unit, and the transmitter is connected to a transmitting antenna; at the same time, the information block consists of a code generation and recording unit, a transmitter, and a transponder with a constant code connected to the power and control unit; wherein the information output unit is designed as a transponder with a permanent code.

IPC class G01S13 / 79

The proposed utility model is illustrated using the schemes shown in figures 1,2,3.

In FIG. 1,2,3 the following designations are accepted: receiving antenna 1, voltage converter 2, detector 3, information processing unit 4, power and control unit 5, information transmitting unit 6, transmitting antenna 7, code generating and recording unit 8, transmitter 9, transponder 10c with a constant code.

In FIG. 1 shows a semi-passive object identification code encoder, FIG. 2 and 3 show embodiments of block 5 of information.

A semi-passive code sensor for object identification works as follows. The receiving antenna 1 receives an encoded signal from the outside (for example, infrared, high-frequency or some other), voltage converter 2 and detector 3 process the received signal and transmit it to the information processing unit 4. The information processing unit 4 compares the received code signal with the code command signal for turning on this particular sensor and, if they are identical, provides a power-on signal to the power and control unit 5. A small battery can be used as a power source in unit 5. The power supply and control unit 5 generates and transmits an information command to the information processing unit through the transmitting antenna 7 of a certain encoded signal or a group of signals that can be repeated at a certain frequency during a given time interval. In FIG. 2 shows an information block 6 consisting of a code generation and recording unit 8 and a transmitter 9 that can transmit a code signal that is variable in content and wave characteristics (for example, frequency, phase, etc.). Block 8 of the formation and recording of the code can change the old and generate a new code in the process of moving the object. In FIG. 3 shows an information block 6 consisting of a code generation and recording unit 8, a transmitter 9 and a constant-code transponder 10 in which, in addition to the variable part of the code signal generated by the block 8, it contains an unchanged carrier which is the transponder 10. The transponder 10 contains information (for example, factory or registration number, etc.) which cannot be changed without mechanical impact. When

if it is necessary to receive only an unchanged signal, the information output unit 6 is implemented as a transponder 10 with a constant code.

Thus, due to the introduction of a voltage converter, detector, and information processing unit into the device, a semi-passive code sensor for identifying a moving object will be included in the operation only from its personal command signal. And due to the introduction of a transmitter into the product, a semi-passive code sensor for identifying a moving object can provide a code signal with various wave characteristics that are not dangerous to human health.
