The invention relates to the field of railway automatics, telemechanics and communication and can be used for application on all types of locomotives to improve security and control of traffic, and in the interval regulation on railway lines.

The known display Device for locomotives, which, in addition to the actual speed display other parameters of the vehicle.

You know the invention of the Readout signal in the cab (see UK patent GB No. 2363235 CL 61 L 3/12). The invention relaying signals passing lights in the cab using an infrared transmitter located on the tracks, sufficient for safe braking distance to the traffic light. The transmitter is connected by electrical wire to each lamp of the traffic light.

A disadvantage of this device is the lack of integrity of the lamps. It is unclear what signal will be displayed on the LCD driver in the case of blown any lamp lights. Failure of the signal indications leads to lower reliability in traffic management, reduces the efficiency in decision making by the driver.

Closest to the claimed invention, the essential features and functional ability which is a display Device for displaying vehicle speed (see German patent DE No. 19901808 A1 class. G 08 G 1/0967). The device determines the vehicle speed based on the data speed sensors, determines the speed limits of the vehicle on the basis of the scan traffic signs and displays this information on the dashboard.

The disadvantages of this device are the lack of warning the driver (the driver) on the approximation of the actual speed to the maximum allowable sound or light signal, which significantly reduces the reaction time of the driver (the driver), as well as limited use of the existing means of display (dashboard) for use only road signs.

The essence of the claimed invention to provide devices of the locomotive display that displays to the operator the maximum possible amount of information required for the safe operation of trains, namely the indication of a traffic light, the value of the actual and allowable speed, direction of motion, the name of the obstacles and distance, using a variety of display types, colors, discrete and range values and provide light and sound alarm enabled by changing the most important from the point of view of security settings.

Comparison savlon the th technical solutions with analogue and prototype allowed us to establish its compliance with the criteria of novelty, since it is not known from the prior art.

The proposed device is industrially applicable and existing technical equipment meets the criterion of inventive step, since it is not obvious from the prior art.

This latter does not identify any transformations, characterized by distinctive features of the prototype the essential features to achieve the technical result.

Thus, the proposed technical solution meets the conditions of patentability result.

The technical result is achieved by the fact that the Locomotive indicating unit is a functionally complete device associated with the devices of the security system through the CAN interface.

The device provides input by the driver with necessary data, and registration of parameters of movement of trains on the built-in cassette registration status of the locomotive safety devices, keeping it in the de-energized condition and subsequent playback.

The cassette registration provides a record of the received information in the nonvolatile memory with the control of records, preservation of recorded information when the power is turned off in a period of time not less than 500 hours, reading the previously recorded information and PE is edacho it in system recovery, a self-test and transfer its current state upon request.

Hardware implementation of the cassette has a watchdog timer to avoid "freezing" of the program tape when the failure of the program. The communication channel enables the serial exchange one wire in both directions.

The locomotive display device displays the information with the possibility of a comfortable reading distance up to 1.5 m with regard to the external light. The brightness of the display elements is adjusted depending on light conditions. In the dark lighting is provided on the label on the front panel, which has anti-reflective coating, protection from direct sun exposure, and provided visibility into the health of display elements.

The locomotive display device has the following modes of operation:

- indication (main);

input locomotive characteristics;

- train input characteristics;

control code waiver;

test.

Together with the locomotive system security device provides the following functions:

- preparation of system information needed by the driver, to indicate;

- display information on the monitor system indicator;

- reception and processing of pressing buttons and rocoto is;

- receive input locomotive and train parameters and their display;

- preparing and disseminating timely information about the movement of trains, diagnosis system, locomotive and train characteristics in a removable cassette registration.

The list of displayed parameters, type of display and color light indicators shown in the Table.

Locomotive indicating unit is presented in figure 2.

Structurally, the device is designed as a unit and consists of a locomotive scoreboard display connected to the encryption module and display with the input of the driver with necessary data and connected to the control module, cassette registration connected with the module coding and registration, which is connected to the control module which controls the operation of the device and connected to the system interface.

All modules are designed with modern components. Software modules written in Assembly language and hardware-oriented high-level language for Cu microcontrollers family INTEL51. For broadcast program files written in the language of Cu was used, the compiler Cu Micro Series 8051 V4.02E/DOS firm IAR Systems. To assemble files written in Assembly language, was used Micro assembler 8051 Series V2.02/DOS firm IAR Systems. To create zagruza the different modules used by the linkage editor Micro Series Universal Linker V4.28/DOS firm IAR Systems.

Figure 1 shows the block diagram of the device containing the locomotive scoreboard display (1), an input connected to the first output of the encryption module and display (2), the first input of which is intended for input of data required by the driver, and the second input is connected to the first output of the control module (3), the first input connected to the second output of the encryption module and display (2). The second output of the control module (3) connected to the first inputs of the module coding and registration (4), and the second input with the second output module coding and registration (4). The third input of the control module (3) connected to the system interface (6), the output of the cassette registration (5) is connected with the second input module coding and registration (4), and input with the first output of the control module and registration (4).

The device operates as follows.

The device of the locomotive display starts immediately after power up. Information from the security system via the system interface (6) is fed to the control module (3)where it is converted to the proper format for transmission in the modules encoding and display (2) and coding and registration (4). Next, the data for display in the module coding and display (2) is encoded and sent to the locomotive scoreboard display (1), and the data for registration in the module coding and registration(4) are encrypted and recorded on the cassette registration (5). Input driver settings through the encryption module and display unit (2) receives the control module (3) for processing and transmission to the system interface (6) and the encryption module and registration (4) for recording on the cassette registration.

The power supply of the device is performed according to the following principle: the power supply from the vehicle is supplied to the secondary power supplies that perform the conversion level of the battery voltage in each module voltage level.
