Description

The utility model relates to means of ensuring traffic safety at railway crossings and can be applied in the transport industry.

A control device for crossing signaling (PS) and railway crossing barrier devices (UZP) is known, containing a housing inside which the control controller of the PS and UZP is located, and also containing an interface for connecting to an external electronic computing device connected to the controller [RU2565159C2, publication date : 11/20/2013, IPC: B61L 23/16; B61L 29/00].

The disadvantage of the known technical solution is its limited functionality, due to the fact that the ability to control and manage the SS and SPD is carried out only by connecting the control device to an electronic computing device (personal computer) located inside the building of the crossing post. Thus, the duty officer at the crossing does not have the ability to monitor and control the substations and SPDs directly from the control device, and the failure of a personal computer can lead to a complete loss of the ability to control and manage the substation and SPDs, which reduces traffic safety at the railway crossing.

As a prototype, the control panel of the PS and SPD was selected, containing a housing inside which the PS and SPD control controller is located, while the housing contains a control panel and control of the PS and SPD connected to the controller [Internet resource: https://web.archive.org /web/20220121044508/https://alfazhat.ru/catalog/pereezdnoe-oborudovanie/shchitki-signalizatsii/shchps-uzp-1-4/, accessed 21.01.2022].

The advantage of the prototype over the well-known technical solution is the ability to control and manage the PS and SPD directly from the shield due to the remote control and control of the PS and SPD, which contains the shield. However, the disadvantage of the prototype is still its limited functionality, due to the ability to control and manage the PS and SPD only through direct interaction of the duty officer with the shield. Thus, the duty officer at the crossing does not have the ability to remotely monitor and control the substation and UZP, which requires the person on duty to be directly near the shield, and if access to the shield is impossible or the shield is mechanically damaged due to exposure to adverse weather conditions and other environmental factors, can also lead to a complete loss of the ability to control and manage the substations and SPDs and reduce traffic safety at a railway crossing.

In view of the indicated shortcomings of the analogue and the prototype, which do not provide the ability to control and control the shield simultaneously from the electronic computing device and from the shield itself, its functionality is significantly narrowed, as a result of which it is required to develop a solution that would provide such an opportunity and at the same time would increase fault-tolerance of the shield due to the possibility of redundant control and monitoring elements of the PS and SPD.

The technical result, which the utility model is aimed at, is to increase the fault tolerance of the control panel of the substation and the SPD.

The essence of the utility model is as follows.

The PS and SPD control panel contains a housing, inside which the PS and SPD control controller is located, made with the ability to connect to the PS and SPD, and also contains a monitoring and control panel connected to the controller. Unlike the prototype, the housing contains an interface for connecting to an external electronic computing device connected to the controller.

The control panel provides the possibility of monitoring and controlling the substation and UZP railway crossing barrier devices. Management means both monitoring the state of the substation and SPD, and direct control of the substation and SPD in normal mode and in the mode of occurrence of malfunctions and emergencies. SPD can be represented by barrier platforms, electric drives for raising platforms, vehicle detection sensors and other means designed to automatically guard the carriageway at railway crossings by raising barrier platforms. PS can be represented by crossing and barrier traffic lights, electric barriers, as well as elements of sound notification.

The interface for connecting to an external electronic computing device provides the possibility of electrical connection of an external electronic computing device with the controller and remote control and monitoring of the PS and SPD, which allows you to expand the functionality of the panel by monitoring and controlling the PS and SPD both through the remote control and through external electronic computing device. The interface can be made in the form of a connector or an electrical connector, while the connector, due to its high fault tolerance, is the most preferred interface for connecting to an external electronic computing device.

The monitoring and control panel provides the possibility of continuous monitoring of the state of the substation and SPD and their control directly from the panel. The console contains controls and monitoring tools.

In this case, the controls can be implemented in the form of single-position switches, such as mechanical buttons or two-position toggle switches, as well as multi-position switches, such as cam switches or three-position toggle switches. The console can be made in the form of a separate unit attached to one of the walls of the housing using known means of movable and fixed connections, or it can be installed in one of the walls of the housing.

The monitoring means may be in the form of indicator lights, such as individual diodes, diode strips or displays, as well as in the form of text labels printed on the console to identify the corresponding indicator lights. The inputs and outputs of the console are connected to the controller and an interface for connecting to an external electronic computing device using electrical connection means.

The PS and SPD control controller is located inside the housing and can be made in the form of a microcontroller or a microprocessor with peripheral devices connected to it. The controller contains inputs and outputs for connection to PS and SPD. The controller also contains inputs and outputs for connection to the monitoring and control panel, as well as inputs and outputs for connection to an interface for connection to an external electronic computing device. The controller is configured to convert the signals coming from the control means of the console or from an external electronic computing device into commands for the PS and SPD. Also, the controller is configured to convert the signals coming from the PS and SPD into indications for the control means of the console or for an external electronic computing device.

As electrical connection means for connecting the above components, wires, cables or contact plates can be used.

A utility model can be made from known materials using known means, which indicates its compliance with the patentability criterion "industrial applicability".

The utility model is characterized by a set of essential features previously unknown from the prior art, characterized in that the housing contains an interface for connecting to an external electronic computing device connected to the controller, thereby providing access from this device to the controller, which eliminates the loss of control and control of PS and SPD in case of failure of the console or external electronic computing device, while allowing the controller to transmit and receive signals both from the console and from the external electronic computing device.

This ensures the achievement of the technical result, which consists in increasing the fault tolerance of the shield, thereby expanding its functionality and improving its performance.

The utility model is characterized by a set of essential features previously unknown from the prior art, which indicates its compliance with the “novelty” patentability criterion.

The utility model is illustrated by the following figures.

To illustrate the possibility of implementation and a more complete understanding of the essence of the utility model, an embodiment of its implementation is presented below, which can be modified or supplemented in any way, while the present utility model is by no means limited to the presented embodiment.

The PS and SPD control panel contains a housing 1, inside of which there is a microcontroller 2 for controlling the PS and SPD with a connection interface 3. On the body there is also a panel 4 for monitoring and controlling the shield, connected to the microcontroller 2 and containing switches and light indicators, and an interface 5 for connecting to a personal computer 6. At the same time, crossing signaling devices, represented by crossing and barrier traffic lights 7 and 8, are connected to interface 3 respectively, electric barriers 9, as well as crossing barrier devices represented by barrier platforms 10, and vehicle detection sensors 11.

The utility model works as follows.

The crossing duty officer monitors the situation at a single-track railway crossing by visually checking the performance and maintenance of devices 7-11, as well as by monitoring the parameters on the remote control 4 located on the shield, or remotely using computer 6 located in the building of the crossing post.

When controlling devices 7-11, control actions are taken into account both from the console 4 and from the computer 6. This means that after the transfer of the control action to devices 7-11, the state parameters of these devices are transmitted via interface 3 to the microcontroller 2, after which the converted signal is transmitted to the console 4 and to the interface 5. This allows you to display up-to-date information about the status of devices 7-11 on the control console 4 and computer 6, as well as provide the ability to control the panel in case of failure of the console 4 or computer 6, as a result of which improves traffic safety at the crossing.

In the event of a malfunction that threatens traffic safety, an indicator lights up on the remote control 4 indicating the presence of a malfunction, and a similar notification is displayed on computer 6. Emergency commands are activated by the duty officer using the remote control 4 or computer 6. This allows the activation of emergency control commands regardless of where the operator is located: in the building of the crossing post or outside it, which also increases traffic safety at the crossing. In this case, in the event of a failure of the console 4, it is possible to control and control the devices 7-11 by means of an electronic computing device.

Thus, the achievement of the technical result is ensured, which consists in increasing the fault tolerance of the panel, thereby expanding the functionality and improving the performance of the control panel of the PS and SPD.
