Description

This invention relates to a technique for contactless magnetic addressing of goods transported on overhead and pusable conveyors. There are known devices that contain magnetic address media mounted on the moving part and recording devices, and read addresses that are installed directly on the conveyor route. Addressing takes place at the points of loading and unloading, the address is read at the junction points of the route, as well as at the points of loading and unloading. At the same time, the address is written on magnetic media in binary code. The write and read operations of the address are performed by various devices, each with its own circuit and vice versa of the equipment providing this operation. All known devices do not provide sufficiently broad functionality for writing and reading multi-bit addresses. . The closest technical solution to an image is a device for recording and combining a multi-threaded address, containing a folder for selecting and setting an address, connected via an encoder to one of the inputs of the signal matching unit, a reading unit, a memory unit, an address writing unit, and the starting element 23. However, the storage of the selected address in the binary code is performed by means of the charge of the capacitors. Capacitors are charged only in those bits in which this address corresponds to the state}. Thus, an address can consist, regardless of the number of bits, of only one significant bit. / I The chain containing the switch contact, diodes, resistors, charging capacitors, is constantly under voltage. Thus, capacitors, serving as the memory of the selected addresses, cannot perceive other information. In addition, the write and read operations of the address are performed once by individual devices, each with its own circuit and set of equipment providing this operation. 1532 The purpose of the invention is to increase the reliability of a device by performing read and write address operations using one set of elements by separating these operations in time. This goal is achieved by the fact that a device for recording and reading a multi-bit cargo address contains a button selection data and an address setting connected through an encoder to one of the inputs of the signal matching unit, a reading unit, a device block, an address writing unit, and a trigger , sensors of beginning and end of recording are entered,. read end sensor, forced reset button, adder, amplifiers, decoder, address selection indicator and read address selection keys, the read block is connected to one of the inputs of the signal matching unit, the other inputs of which are connected respectively to the start sensor and end sensor a record whose input is connected to the inputs of the sensor of the end of reading and the forced reset button :, the outputs of the signal conditioning unit are connected to one of the inputs of the memory unit and one of the starting element, the other output of the signal conditioning unit is connected to other inputs of the memory unit and the trigger element, the output of which is connected to one of the inputs of the adder, the outputs of which are connected through the first amplifier to the address- sa recording unit, while the outputs of the memory unit are connected to other inputs of the adder and the inputs of the decoder, the outputs of which through the second amplifier are connected to the address selection indicator and the keys of the selection of the read address. Figure 1 shows the functional diagram of the device; figure 2 - layout of devices. one. . The device comprises a keypad 1 for selecting and setting an address, an encoder 2, a signal matching unit 3, a memory block 4, triggered on triggers, a recording start sensor 5, a recording termination sensor 6, a trigger element 7 trigger, a decoder 8, an amplifier 9, an indicator 10 address selection, the adder P, amplifier 12, block 13 of the recording address, button 14 forced reset, block 15

The proposed device performs the tasks of writing and reading the address. Install the addressers, readers and sensors on the conveyor track; on the rolling stock -; address carriers, and in the workplace - consoles, in which mounted: we are the circuit elements

Record and scoring addresses I

The carrier is

a plate of magnetic material on which information is recorded in the form of magnetized sections according to the number of bits of the information being transferred. : The addresser consists of electrostromagnets that create an electromagnetic field. The number of electromagnets is determined by the number of bits written to the information carrier. . .

The reader contains induction sensors-flux-probes, according to the number of bits of the information read from the address carrier.

When the rolling stock moves, when the address carrier passes by the addressee, the address is recorded, and when the address carrier passes by the reader, the address is read.

When recording the device works as follows.

One of the buttons on panel 1 is the address. This signal is converted by the diode matrix of the encoder 2 into a group of signals which, through the signal corjia block 3, reach the memory block 4 executed on triggers.

The number of triggers, and consequently, the correctness of the address chosen by the operator, is controlled by the corresponding lamp on the indicator panel 10. This lamp is switched on by its decoder channel 8 through one of the amplifiers 9. At the operator's command, the carriage with the load starts to exit from the stop. In its movement, the trolley acts on the sensor 5 start recording. This signal includes a trigger element 7 (trigger) through a signal matching unit. The block triggers of blocks 4 and 7 are summed on adder 1, where write commands are generated in all bits, the signals can be direct (,) or

inverse (O). Through the appropriate amplifier I2, the magnets of the address writing unit 13 are turned on. At this time, the address carrier passes by the addressee and receives information - the address.

Continuing to move, the cart will act on the sensor 6 of the end of the address recording. In this case, all the triggers of blocks 4 and 7 are returned to the initial position, the blocks of P13 are turned off, the recording of the address is stopped.

The device, when reading the address, works in the following way. With the passage of the address carrier, it is only that the block 15 reads at the outputs

signals appear last. These signals, the diode array of the cipher 2, pass through one bit through

a block 3 of matching signals to a block of 4 memory, where it is stored ..

Signals from the outputs of the triggers of block 4 are converted by a decoder 8 into one signal, which appears on one of the outputs of the decoder 8 and is amplified by the corresponding channel of amplifier 9. This signal falls on one of the indicator panel lamps 10. If this high If the phone 9 is connected by one of the keys 17 to the decoder 8, then the last one will receive the signal of the selected address matching. Readout done.

In its subsequent movement, the carriage acts on the sensor 16 for the end of reading. If the signal is through

its channel formers returns. triggers of block 4 in the initial position; blocks 8, 9, 10, 7 and 18 are turned off. The device is ready for the operation - write the address.

In addition, since the readable address., I.e. the address is arriving at the working place of the trolley, and the set up addresses for sending from this work place are always different, the address matching signal; and the signaling indicator of the address given is passed through different channels of amplifier 9.
