Description

(54; READING DEVICE OF INFORMATION from mobiles The invention relates to automation and telemechanics in transport and can be used for automatic reading of information from transport objects. A device for reading information from mobile objects containing code elements mounted on a mobile object and executed in the form of a matrix of permanent magnets, fitted with control magnets, sensitive elements, made in the form of a set of vertically oriented information and control magnets Circuits are connected to a logical signal processing unit, and a decoder with an indication unit Cl. A disadvantage of the known device is that when a large amount of information is read, the dimensions of the code matrix and the increase of OBJECTS increase, the accuracy of the read information increases. the readability of information. The goal is achieved by the fact that the block of logical information signal processing consists of serially connected memory registers and, comparison blocks and triggers connected by outputs to the decoder of blocks of information and control signals, an adder, a pulse generator, a row row counter of the matrix connected to one trigger inputs, and logic elements AND and OR, the output of which is connected to the counter input, and the inputs to the outputs of the And elements connected by the inputs to the corresponding outputs of the selection blocks of the control signals, while the outputs of the allocation blocks of the information signals are connected to an adder, the output of which is connected to the third inputs triggers and memory registers.

the other inputs are associated with a pulse generator connected to the output of the OR element, the control magnets are installed at the ends of each row of the matrix, and the information flux-probes are arranged in one row and connected respectively to blocks of information and control signals.

FIG. 1 is a block diagram of the device; in fig. 2 - location of the code matrix magnets.

The device includes a matrix 1 fixed on a movable object, containing code elements of permanent information magnets 2 and control magnets 3 located along the edges of each row of the matrix with a drawn polarity.

Vertically oriented informational 4 and control fluorescent readout 5 sensing elements) are arranged in one row and connected to the allocation units of informational 6 and 7 coarse signals.

The blocks 6 are connected to the registers 8 of the memory of the block 9 of the logical signal processing. The registers 8 of the memory are connected to the decoder 12 connected to the display block 13 via the comparison blocks and the flip-flops 11.

The control signal extraction units 7 are connected by AND gates and 14 and 15, the outputs of which through the OR 16 element are connected to a counter -17 rows of matrices and a pulse generator 18. The outputs of the blocks 6 are also connected to the inputs of the modulator 2 operating adder 19, the output of which is connected to the corresponding inputs of the flip-flops 11.

The device works in the following way.

When the flux-gates 4 and 5 are moving over the code matrix 1, the control flux-gates 5 determine the moment of coincidence with the row of magnets. At the time of combining, the signals of the control flux probes 5 through the signal extracting units 7, the elements 14 and 15 and OR 16 arrive at the input of the counter 17 lines and the generator 18 clock pulses.

A generator 18 starts operating, controlling the shift of registers 8 into which information is recorded from informational flux probes 4.

Recorded three times in the register 8 memory information line code

Matrix 1 is compared and entered into triggers I1 to the maximum of the same readings. The adder 19 monitors the information in the parity line and, if an error is detected, prohibits the recording of information in the triggers 1 1.

The row counter 17 controls the triggers 11, allowing sequential input of information from each row of matrix 1.

Thus, the operation algorithm of the device allows a parallel-serial method to read information from the code matrix, and with each, and the second row, the information is read three times by a parallel method and statistically processed. From all lines, the information is read in a sequential manner and when an error is detected in reading from an element. 4 is reflected in indicatry 13.
