Description

 The invention relates to simulator building, and in particular to optical-electric systems simulating the external environment, and can be used to visualize a picture of the environment presented to the driver during training in driving skills and control a tracked vehicle.

 The practice of teaching caterpillar driving in difficult road and weather conditions has shown that driver mechanics do not have the skill to use a hydropneumatic cleaning system (GPO), which leads to a decrease in the average speed. Therefore, there was a need to create a simulator that would allow to develop the appropriate skill.

 There is a well-known unified trainer of the TTV type for learning how to drive combat vehicles (see. Learning how to drive combat vehicles on educational and training means. - M .: Voenizdat, 1992, p. 28 - 32), consisting of a cabin, a cradle and a frame, with movement controls , a button mounted in the right turn control lever, a driver’s observation device, a driver’s seat, a film projector and an instructor’s console. The disadvantage of this simulator is that it does not simulate conditions that impede the visibility of the driver while driving, such as contamination of the exit window of the viewing device, rain, fog, which does not allow the student to get driving skills in difficult road and weather conditions and skills using the GPO system during training.

 The objective of the invention is to increase the efficiency of existing simulators for driving training of driver-mechanics of tracked vehicles by simulating poor visibility conditions to achieve the simulator’s adequacy to a real tracked vehicle, as well as to develop the learner’s skill in driving a tracked vehicle in difficult terrain conditions and when poor visibility.

 This problem is solved by introducing into the well-known driving simulator an additional device consisting of the following elements: a converter, an electric motor, a limit switch block, a drive and a driven pulley, a frame with an inserted organic glass coated with a special coating, a lever connecting the driven pulley and the frame. All of the listed elements of this device are fixed on a plate, which in turn is installed and mounted outside the simulator’s cabin, in front of the driver’s observation device.

 In addition, a button is connected to the device via limit switches to turn on the GPO system, which is mounted in the right rotation control lever.

The invention is illustrated in figures 1 and 2:

FIG. 2. Driving simulator. Structural and functional diagram of a device for simulating poor visibility.

 A low visibility simulator 6 is included in the driving simulator; a functional block diagram is shown in FIG. 1, which includes: a cabin with a cradle and a frame 1, a driver’s seat 2, a driver’s observation device 3, traffic controls 4 with a GPO button 5 mounted in the right rotation lever, an instructor remote 8, a movie projector 9, and a converter 7 electrically connected to the instructor's remote control, film projector and GPO button.

 The composition of the device for simulating poor visibility, the structural-functional diagram of which is presented in FIG. 2, a plate 10 is included, which is installed on the simulator’s cabin in front of the driver’s observation device, on which are mounted: an electric motor 11, a drive pulley 12, a driven pulley 14, a frame 15 made in the form of a frame with an inserted organic glass having a special coating, a lever 16, thread 13 connecting the leading and driven pulleys, the limit switch block 17.

 A PT-27 type converter containing a step-down transformer, a rectifier bridge and a time relay; electric motor - any, for example MN-145 (27 V); limit switch block, for example D-703; drive and driven pulleys - standard; frame - is made in the form of a frame with an inserted organic glass having a special coating, the lever connecting the driven pulley and the frame is made.

The visual environment simulation device operates as follows:
27 V voltage is supplied through the converter 7 to the instructor 8 remote control, which is designed to control the simulator and, in particular, the simulation device 6. The instructor’s control panel has an error recording unit and a switch that supplies and disconnects 27 V voltage to the simulation device. In addition, a voltage of 27 V is supplied from the instructor's remote control to the GPO 5 button and film projector 9.

 When a voltage of 27 V is applied from the instructor’s remote control to the simulation device 6, the frame is lowered, which, having lowered in front of the monitoring device 3, the driver mechanics simulates poor visibility of the driving route, which forces the driver to react in a certain way (stop the driving simulator or turn on the GPO system). In the case when no response occurred from the driver side, within 10 seconds, the time relay, included in the general circuit of the converter 7, trips, turning off the power of the movie projector 9, and an error is recorded on the operator panel 8.

 In the event that the driver has responded correctly and pressed the GPO button, a circuit closes, a voltage of 27 V is supplied to the electric motor of the simulation device 10, the device frame rises, closes the limit switch 17 and the motor stops. Using the light indication, a signal is sent to the instructor’s console about the correct completion of this task by the driver.

 In the process of practicing a driving exercise on a simulator with an installed simulation device, the instructor can issue commands to the simulation device several times, depending on the route shown by the training film. This in turn will contribute to the development of certain skills in working with the GPO system when driving in conditions of poor visibility.
