Description

 The proposed device relates to the field of automation and computer technology and can be used for training in traffic rules.

A device for studying traffic rules at intersections is known, comprising a panel on which a map with a picture of task conditions is located, mock-ups of vehicles, control knobs for entering task conditions and entering a student’s answer, a logical circuit is located on the back of the panel [1]
However, the device does not have enough information for the learning process.

 The closest in technical essence (prototype) to the proposed device for modeling traffic rules for teaching traffic rules is a device for teaching traffic rules at regulated intersections [2] containing a distributor of traffic options, the output of which through the switching unit is connected to the first input of the commander of traffic options, the output which is connected to the input of the display unit.

 The disadvantage of this device is the lack of information and the lack of the ability to quickly change the traffic situation in the learning process.

 The aim of the invention is to expand the functionality of the device to increase the visibility of learning and expand the didactic capabilities of the device.

 This goal is achieved by the fact that a data input unit, a data control unit, a unit for simulating the movement of dynamic objects, a first and second memory unit, a comparison circuit, and an output of a unit for distributing movement options and a first are introduced into a device containing a distributor of motion options, a switching unit and an indication unit the output of the data unit is connected to the input of the data control unit, the first output of which is connected to the first input of the display unit, and the second to the input of the switching unit, the output of which is connected to the first input with comparison with the inputs of the first and second memory blocks, the output of the first memory block is connected to the second input of the display unit and the first input of the block for modeling the movement of dynamic objects, the second input of the comparison circuit is connected to the output of the second memory block, the output of the comparison circuit is connected to the second input of the block simulation of the motion of dynamic objects, the third input of which is connected to the second output of the data input unit, and the output of the block of motion simulation of dynamic objects is connected to the third input of the display unit.

 The introduction of distinguishing features made it possible to create any traffic situation for the selected type of intersection, set traffic for vehicles, create road signs and marking lanes, introduce any kind of transport, and also visually simulate the current situation in dynamics from the point of view of correct decision making.

To explain the invention, the following is a description showing, by way of example, an embodiment of a device with reference to the accompanying drawings in which:
figure 1 functional diagram of the device,
figure 2 an example of the execution of data control blocks,
figure 3 an example of the execution of the block modeling the movement of dynamic objects.

 The proposed device (Fig. 1) contains a data input unit 1, a data control unit 2, a switching unit 3, a first memory unit 4, a dynamic object motion modeling unit 5, an indication unit 6, a second memory unit 7, a comparison circuit 8 and a distribution unit 9 movement options, the first output of the data input unit 1 and the output of the motion option distribution unit 9 are connected to the input of the data control unit 2, the first output of which is connected to the first input of the display unit 6, and the second output to the input of the switching unit 3, the output of which is connected from the first m is the input of the comparison circuit 8 and with the inputs of the first 4 and second 7 memory blocks, the output of the first memory block 4 is connected to the second input of the indicating unit 6 and to the first input of the motion simulation block 5 of dynamic objects, the second input of the comparison circuit 8 is connected to the output of the second block 7 memory, and the output of the comparison circuit 8 is connected to the second input of the dynamic object motion modeling block 5, the third input of which is connected to the second output of the data input unit 1, and the output of the dynamic object motion simulation block 5 is connected to the third Odom display unit 6.

 The data input unit 1 is intended for entering codes and parameters into the device of images selected by the operator (modes of transport and their parameters, types of signs, types of markings and obstacles, etc.), as well as a signal for activating the movement of objects (vehicles).

 Unit 2 data control monitors the correctness of the entered data (compliance with the entered data codes and their parameters).

 The switching unit 3 performs switching of the entered information depending on the code of the entered image with the first 4 and second 7 memory blocks and a comparison circuit 8.

 The memory unit 4 is intended for storing images of information by mode of transport, types of crossroads, marking of lanes, obstacles, road signs, etc.

 Block 5 modeling the movement of dynamic objects organizes the computing process for displaying dynamic information on the display unit (traffic).

 The indicating unit 6 is intended for visual display of static and dynamic information (coordinate-sign indicator).

 Block 7 memory is designed to store codes for standard situations of wiring vehicles.

 Comparison scheme 8 is intended for comparing codes of standard situations of wiring of vehicles with codes of wiring of vehicles entered from the input panel.

 Block 9 distribution of traffic options is designed to select the types of intersections (can be structurally performed in one block with block 1 data input).

 The device operates as follows.

 The operator using the block 9 distribution of options for movement enters the code of the selected type of intersection and its parameters. In the data control unit 2, the entered code values are compared with the possible ones and a signal is generated that, in the case of incorrectly entered data, comes from the first output of the data control unit 2 to the first input of the display unit 6, where the code of the entered intersection is displayed. In this case, the data entry must be repeated. Otherwise, the information entered using the switching unit 3 is connected to the corresponding segments of the first 4 and second 7 memory blocks.

 In the first memory unit 4, information is selected in accordance with the entered code of the type of intersection and is fed to the second input of the indication unit 6 to display static information (type of intersection). Then the operator sequentially enters from the data input unit 1 (if necessary) the codes of the type of transport, signs, striping, type of interference, the sequence of the wiring of vehicles, etc. which are sequentially checked in block 2 of the data control, similar to the control of codes of types of intersections. The information entered using the switching unit 3 is connected with the corresponding segments of the first 4 and second 7 memory blocks and the first input of the comparison circuit 8. Static information is read from the first memory block 4, which is transmitted to the indication block 6 and simultaneously to the first input of the dynamic motion simulation block 5 objects (type of transport code, direction code, initial location coordinates, speed, intersection type code). The code of the type of transport is also fed to the input of the second memory unit 7. The codes of the transport wiring sequence are sent to the first input of the comparison circuit 8. From the second memory block 7, the sequence of codes of the standard wiring of the transport is received to the second input of the comparison circuit 8 (in accordance with the entered codes of the type of intersection and type of transport). If the entered transport wiring order does not correspond to the standard one, then in the comparison circuit 8 a signal is generated that goes to the second input of the block 5 for modeling the movement of dynamic objects.

 After entering all the static information and if there are no messages about incorrectly entered data on the display unit 6, the operator by the "start" command, entered from the data input unit 1, initiates the start of the computational process of moving dynamic objects. This signal from block 1 data input is fed to the third input of block 5 modeling the movement of dynamic objects. From the output of the block 5 modeling the movement of dynamic objects, dynamic information about the state of vehicles (their movement along the indicator is the new location coordinates) and, in the case of an error in the order of the wiring of vehicles, an error sign (a circle with a red cross superimposed on the emergency objects) is sent to the third input block 6 indication to display them. The rate of delivery of dynamic information is set by the pulse generator, which is located in block 5 modeling the movement of dynamic objects.

 These blocks and nodes can be performed on known elements of digital technology.

 The data input unit 1 and the motion option distribution unit 9 are standard digital information input panels.

 Block 2 data control (figure 2) can consist of two registers 10 and 11, a decoder 12, a memory node 13, a comparison circuit 13, a block of elements And 15 and a block of keys 16.

 From the output of the data input unit 1 or the motion variant distribution unit 9 (Fig. 1), information is input to the data control unit 2 (Fig. 2). And on the register 10 the code of the input data is received, and on the register 11 the data itself. From the output of the register 10, the data code is sent to the decoder 12, which, in accordance with the entered code, connects the necessary sector of the memory node 13, in which the standard data set assigned to the specific code is pre-recorded. From the memory node 13, a standard data set is fed to the first input of the comparison circuit 14, the second input of which receives data from the register 11. In the case of correctly entered data, the signal generated in the comparison circuit 14 opens the key block 16 and the information from both registers 10 and 11 arrives at the second output of the data control unit 2 for further processing. In the event of an error during data entry, the signal generated in the comparison circuit 14 is fed to the second input of the AND block of elements 15, the first input of which receives the code of the entered data and the data code for which the data set is incorrect, is fed to the first output of the data control unit 2 for display in the future on the display unit 6.

 Block 5 modeling the movement of dynamic objects (Fig. 3) may consist of 9 memory registers (from 17 to 25), two current time sensors (26, 27), a pulse generator 28, a memory block 29, two memory nodes (30, 31) , four adders (32 to 35), four multipliers (36 to 39), two subtractors (40, 41), eight keys (42 to 49), an And 50 element, two key blocks (51, 52), a block comparison 53, comparison circuit 54, comparison element 55.

 Block 5 modeling the movement of dynamic objects works as follows.

The key blocks 51 and 52 are in the open state. The input 1 of the block 5 of modeling the movement of dynamic objects from the output of the block 4 of the memory (Fig. 1) receives the following data: code of the selected direction of traffic (K _n ), code of the form of the intersection (K _p ), coordinates of the initial location of the transport (X _n , Y _m ) and the components of the speed of transport (V _x , V _y ), the code of the type of transport (K _t ), which are recorded respectively in seven memory registers from 17 to 23 (Fig. 3).

 At the input 2 of the block for modeling the movement of dynamic objects, a signal is received if it is developed in the comparison circuit 8 (Fig. 1) about an error in the alleged wiring of vehicles.

 The input 3 of the block for modeling the movement of dynamic objects receives a signal from the data input unit 1 (Fig. 1), which starts the pulse generator 28 and the first current-time sensor 26 (Fig. 3).

The pulse generator 28 periodically polls the first current time sensor 26 and the current time (T _tech ) is regularly updated and fed to the first inputs of the multipliers 36 and 37, the second inputs of which, respectively, also receive information from the memory registers 21 and 22 (V _x , V _y ).

From the outputs of the multipliers 36 and 37, the signals corresponding to the increments of the path (D _x V _x * T _tech , D _y V _y * T _tech ), traveled by the dynamic object along the coordinates X and Y, are respectively supplied to the first inputs of the adders 32 and 33, to the second whose inputs are the initial values of the coordinates of the location of dynamic objects (vehicles) X _n and Y _n from the registers 19 and 20, respectively, also with the pace of the pulse generator 28. From the outputs of the adders 32 and 33 the current values of the coordinates of the dynamic objects (X _tech X _n + D _x , Y _tech Y _n + D _y ) with the pace of the generator An array of pulses 28 are supplied to the inputs of the comparison unit 53, to the register 24 (X _tech ) and the register 25 (Y _tech ), and then, with the update rate of the information in the pulse generator 28, they are output to the block 5 of modeling the movement of dynamic objects through key blocks 51 and 52 . At the same rate, the code of the mode of transport from registers 23 is also issued.

The output of the registers 24 (X _tech ), in addition, is connected to the first inputs of the adder 34 and the subtractor 40, and the output of the registers 25 (Y _tech ) with the first inputs of the adder 35 and the subtractor 41. In the comparison block 53, the values of the current coordinates of the object (X _tech , Y _tech ) with the coordinates of the center of the intersection (X _c , Y _c ) received with the update rate of the information in the pulse generator 28 from the memory unit 29, the input of which is a signal corresponding to the code of the intersection, arriving at the same rate from register 18. When achievement of equality of values (when coinciding with coordinates, that is, when the dynamic object reaches the center of the intersection) in the comparison unit 53, a signal is generated that enters the control input of the key 42 and opens it, which starts the second current-time sensor 27, which enters the control input of the key block 51 and closes it and arrives at the first input of the And 50 element. This is due to the fact that when the dynamic object reaches the center of the intersection, the wiring of vehicles introduced by the operator must be implemented, and the dynamic object must change its movement accordingly There is a direction entered.

The increment of the coordinates of dynamic objects D _x1 , D _y1 after they pass the center of the intersection are obtained at the outputs of the multipliers 38 and 39 (which implement the expression V _x * T _tech1 D _x1 , V _y * T _tech1 D _y1 , where T _{tech1 is the} current time value after passing the intersection obtained from the second current-time sensor 27, which starts after the dynamic object passes through the center of the intersection, and V _x , V _y are the velocity components obtained respectively from the memory registers 21 and 22).

Then, depending on the direction of movement of the vehicle chosen by the operator (the value of which is read from the register 17 to the input of the comparison circuit 54), a signal is generated in the comparison circuit 54 that opens the keys 48, 49, 45, 47 (if the vehicle turned right or continues to move up on the screen) or keys 48, 49, 44, 46 (if the vehicle turned left or turned 180 ^o ). The newly obtained vehicle coordinates (X _tech X _cn ± D _x1 , Y _tech Y _cn ± D _y1 , where X _cp , Y _cp 1 are the coordinates of the dynamic object at the time it passes the center of the intersection, received from registers 24 and 25, respectively, are received on a key block 52, which is open in the normal state and, thus, the coordinates of the dynamic object with the update rate specified by the clock pulse generator 28, are output from the block 5 simulating the movement of a dynamic object.

 If there is a signal at the input 2 of the block 5 simulating the movement of a dynamic object that enters the second input of the And 50 element and after the vehicle passes the center of the intersection (there is a signal at the first input of the And 50 element), a signal is generated in the And 50 element that opens the key 43 and the error sign code (red cross in the circle) is received from the memory node 31 through the key block 52 to the output of the block 5 modeling the movement of a dynamic object.

 The memory node 30 is designed to store the maximum value of the display time of a dynamic object after passing through the intersection, which is periodically (with the pace of the pulse generator) compared in comparison element 55 with the current time of the second current-time sensor 27, launched after the dynamic object passes the intersection.

 When these values are equal, a signal is generated that enters the control input of the keys 52 and closes it. This operation of block 5 modeling the movement of a dynamic object ends.

 The remaining elements and blocks are standard, known in digital technology and can be performed, for example, on elements of the K-155 series.

 The application of the proposed device allows you to create a variety of traffic situations with various modes of transport from a set of standard elements and images and have a complete set of all standard situations and their wiring according to the requirements of the "Rules of the Road", which can significantly increase the functionality of the device and expand its didactic capabilities.
