Description

The invention relates / to the means of automation of intra-factory transport, such as cargo trucks overhead conveyors. To increase accuracy and simplify

The device's addressors 3 are made in the form of vertical plates equally distant from each other reflecting ultrasound, which are located at equal distances also in the direction of travel of the vehicle 1, on which the transceiver 2 of ultrasonic signals is installed. When the vehicle is moving, the signals emitted by the transceiver 2 are reflected from the plates of the address carriers 3. Address carriers 3 are made in the form of a necessary set - a combination of plates reflecting ultrasound. The received signal corresponds to the code of the address position, since the reflected signals record the presence or absence of plates in the address set at each location. 2 Il.

The invention relates to the automation of intra-factory transport and can be used to address freight vehicles, such as cargo carriages for overhead conveyors.

The aim of the invention is to simplify the addressing device and increase its reliability.

The principle of operation of the device is based on the use of radiation by an ultrasonic transmitter of a short probe pulse and a time separation of the reflected ultrasonic vibrations from the code-information and service reflective plates due to the arithmetically progressive distance from the transceiver of the ultrasonic vibrations to each code plate.

Serially arranged vertically and equidistant from each other in a direction perpendicular to the direction of movement of the vehicle, the plates provide a sequence of reflection of ultrasonic signals, which will be the address information. The plate placement structure at each unloading-unloading position is different and corresponds to the address code of this position.

FIG. 1 shows the structure of the device; in fig. 2 is a view A of FIG. one.

A device for automatically addressing a vehicle contains an ultrasonic signal transceiver 2 installed on a vehicle 1 and address carriers installed at the unloading-loading position and made in the form of plates 3 reflecting ultrasound. 3 The plate placement structure corresponds to the position address code.

The proposed device works as follows.

On the information-master unit (not d shown), the moving address of the vehicle 1 is set, which has transceiver 2 ultrasonic signals. The vehicle 1, moving, at the approach to the addressing position, radiates a probe ultrasonic pulse cyclically and receives signals reflected from the plates 3 in a certain sequence. Moreover, the receiver, taking 5 hence the reflected signals, captures the absence and presence of reflecting plates 3 at each information site. The amplified and formed pulses are transmitted to the transceiver ultrasound device into the software device, which is also located on board the vehicle 1 (not shown).

If the service signals that are reflected from the corresponding plates correspond, the program code stores 5 information codes. At the same time, the vehicle control device will know the position of the position on the road and can make the necessary decision - either to continue driving, or to start braking, or to stop, • θ The arrangement of the reflecting plates in space is three-dimensional, i.e. they are equally spaced horizontally and verticals, allows you to encode information by the absence of any plates in the adressor. This eliminates the influence of changes in the speed of movement of the vehicle and external factors. The code signals of the address points correspond exactly to the code pattern of the plate placement.
