The invention relates to the automation of electric transport and can be used, for example, to address and control electric freight carriers of monorail roads.

The purpose of the invention is to increase productivity by increasing the number of transmitted addresses without increasing the number of control trolleys.

FIG. 1 shows a block diagram of the device; in fig. 2 - the same, with the disclosure of blocks located on the vehicle and at the workplace; in fig. 3 is a diagram of an address setting unit with a switch and control buttons; in fig. 4 is a block diagram of an address reading unit; in fig. 5 is a block diagram of an addressing unit with memory elements and keys.

The device (Figs. 1 and 2) contains the address reading unit 2 with the nodes 2.1-2.3, the address unit 3, the switching unit 4 with the control 4.1 and the switching 4.2 and 4.3 elements located on the vehicle 1 (the number of which depends on the traffic flow of the route) , electric drive control unit 5. The current collectors b, 7 and 8 of the vehicle 1 are moved along the power trolls 9, 10 and 11, the current collectors 12, 13 and 14 - along the control trolls 15, 16 and 17. A three-phase mains voltage is applied to the power trolley. The electric drive control unit 5 is connected to the current collectors 6, 7 and 8 of the power supply trolls 9, 10 and 11 and the address reading unit 2. The addressing unit 3 contains memory elements 18.1-18.18 (FIG. 5), performed, for example, on remote switches, and keys 19.1-19.18. Instead of keys 19.1 - 19.18, in this example, the contacts of remote switches 18.1-18.18 are used. The keys 19.1-19.18 are connected to each current collector b, 7, and 8 of the power supply trolls 9, 10, and 11 directly, through diodes 20-25 in the forward and reverse directions. The inputs of the address unit 3 are connected to the outputs of the address reading unit 2, and the outputs, via switching elements 4.2 and 4.3, to the current collectors 13 and 14 of the control trolleys. Block 2 (FIG. 4) of the address reading consists of three nodes 2.1; 2.2 and 2.3 readout of the address, the inputs of this unit are directly connected to current collectors b, 7 and 8 of trolls 9, 10 and 11 of the power supply and with one current collector 12 of the control trolley 15 and through switching elements 4.2 and 4.3 of the switching unit 4 with other current collectors 13 and 14 trolleys 16 and 17 controls.

The address setting unit 26 (Fig. 3), located at the workplace (Fig. 2), consists of switches 27.1 and 27.2 and control buttons 28. The address setting unit 26 is connected (FIG. 2) to each power supply trolley 9, 10, and 11 directly.

through the diodes 29-34 in the forward and reverse directions, and the outputs - directly to the control sections 35, 36 and 37 of the trolleys 15, 16 and 17.

Block 38 address reading is located on the path of movement of the rolling object in the workplace, on switches and on the lifting and lowering sections, similar to block 2 address reading, located on the vehicle 1 and

0 consists of two address reading nodes 38.1 and 38.2. The address read address block 38 is connected (Fig. 2) to control sections 36 and 37 of trolls 16 and 17 and to power supply trolls 9, 10 and 11, and outputs to block 39

r control mechanisms of the route (a switch, lifting and lowering section, etc.).

Each of the nodes 2.1; 2.2; 2.3; 38.1 and 38.2 address readouts include resistors 40-

0 45 (fig. 4), diodes 46-51, 52-57 and relay 58 with contacts 58.1; 58.2 and 58.3; relay 59 with contacts 59.1; 59.2 and 59.3; relay 60 with contacts 60.1; 60.2 and 60.3; relay 61 with contacts 61.1; 61.2; 61.3; relay 62 with contacts 62.1; 62.2 and 62.3 and relay 63 from contact 5 and 63.1; 63.2 and 63.3.

The block 39 is located at workplaces in the movement path of the movable object and is performed at the comparison node, unit code and ten code setters, one-shot and amplifier, relay with closing contacts, relay with switching contacts, diode and power supply unit (not shown).

The control unit 39, designed to control the switch, is located on the switch points in the path of movement of the movable object and has two modifications - the switch control unit for branching and the switch control unit for merging. Block 39 of the control. The switch to branching also contains a comparison node, a code setter, a power supply unit, OR-NOT, AND-NO elements, an output signal relay, a diode, and an arrow motor K1-K4.

, manual translation buttons, operating mode selection switches (automatic and manual control) (not shown). The block 39 for controlling the switch for the fusion differs from the block of the switch for the switch for branching in that there is no comparison node in it. The lifting and lowering section is a switch to several directions, therefore the control unit of the lifting and lowering section does not differ significantly from the unit

5 control switch.

The device works as follows.

At the address assignment site (at work

place) diodes 29-34 form nine code combinations from a three-phase network voltage. Each code pattern can be connected to any of the three control trolls 15, 16 and 17. Two troll controls 16 and 17 are used to transmit address information, and the third of the trolls (15) is used to send control commands to the mobile unit 1. Before sending the vehicle 1, the operator of one of the buttons 28 ("Reset) resets the old address, and the switches 27.1 and 27.2 and another button 28 enters a new address and presses button 28 “Departure. The reset signal from the troll 11 directly through the disconnecting contacts of the buttons enters the section 35 of the troll control 15, and then to the input of the address reading unit 2.1. Each of the nodes 2.1; 2.2 and 2.3 readout of the address selects one of the nine code combinations received by one trolley. When the Reset signal at node 2.1 of the address reading arrives, relays 60 and 63 are triggered (Fig. 4), which connect the reset windings of remote switches acting as memory elements 18.1-18.18 of the addressing unit 3 with their serially connected make contacts 60.2 and 63.3. The new address is recorded when the corresponding button 28 is pressed. Through the closing contacts of the other buttons, recording and address information signals are sent to the control sections 35, 36 and 37 of the terminals 15, 16 and 17. The signal "Record from section 35 of the troll" is fed to the input of node 2.1 of reading the address. In node 2.1 of the reading, relays 58 and 61 are triggered. A signal appears from the output, which turns on control element 4.1 of switching unit 4. Switching elements 4.2 and 4.3 of switching unit 4 connect sections 36 and 37 to corresponding inputs of nodes 2.2 and 2.3 of reading addresses. The address information, depending on the position of the switches 27.1 and 27.2, is read by the readout unit 2 and stored by the remote switches 18.1-18.18 in the addressable unit 3. Remote switches 18.118 .18, with their contacts 19.1-19.18, acting as keys, connect one of the code combinations specified by diodes 20-25 (Fig. 5) to the control troll 16 and 17 in accordance with the recorded address information after releasing the button 28 " Record. Moving along the track, the means 1 on the move successively connects its address to the address read blocks 38 located in the work stations of the turnouts to the ramification and lift sections. When a moving object passes through the workplace, the address information from the current collectors 13 and 14 through the partitioned sections 36 and 37 enters the address reading block 38. The read address information enters the comparison node, located in the workplace management unit 39, and is compared with the address of the workplace, which is fixed for each workplace, from the setters of the code. The comparison is made with two four-bit comparators, one of which compares the bits of the units, and the other of the bits of the tens. When the address of the means 1 coincides with the address of the workplace at the output of the comparison node, a coincidence signal appears, including a one-shot and a relay, which sends to the control section 35 of the troll 15 a short stop command formed by connecting the power troll 11 to the current collector 12 of the means 1 via a diode, included in the opposite direction. In the tool 1, the readout node 2.1 reads the stop command and issues it to the drive control unit 5, where the movement drive is disconnected by this command. Further control of the vehicle 1 at the workplace is performed from the address setting unit 26 by means of switches and control buttons. The operator using the buttons “Forward and“ Back stops the moving object exactly at the position. The Down button will release the container on the vehicle, then the container will be loaded or unloaded, after which the operator will lift the container and send the vehicle with the Up button. When a moving object is in the workplace, there is a signal at the output of the comparison node, which activates the relay through an amplifier, blocking the next vehicle's approach with the command "Stop while the first vehicle is in the workplace area, and when leaving the workplace area, the last relay turns off and the “Departure” command allows the approach of the next vehicle. If the address does not match the addresses of the next workplace, the vehicle passes through it without stopping. When it approaches the switch, the object address code enters the control sections 36 and 37 of the trolleys 16 and 17, is read by the readout node 38.2, and then enters the comparison node of the switch control unit 39. If the first digit of the vehicle address is the same as the branch address, a matching signal appears at the output of the comparison node of the corresponding block 39. The switch can be in any position: "Forward or" Rotated. If the switch in the position "Direct and a match signal appears, the relay is activated, removing the signal" Departing from section 35, formed by connecting the trolley 9 to the power supply to the current collector 12 of the moving object 1, and sends the command "Stop and thus blocks the approach to the switch of funds means 1 at the time of its transfer. Reading and setting the address can be done without stopping the moving object, which shortens the addressing time.

Reading and setting the address can be done on the same part of the route. In this case, it is possible to control the recorded address information.

From the switches, workplaces, lifting and lowering sections, you can implement any configuration of the route (monorail).
